Abstract:
A workpiece holding device includes a main body having a groove and a bearing plate configured to receive a workpiece; an elastic member mounted in the groove at an angle relative to the bearing plate, and having an engaging portion protruding beyond the groove; and a resisting member having an inclined surface received in the groove. The inclined surface can abut the elastic member. When the resisting member rises it forces the engaging portion of the elastic member to move toward the bearing plate, thus securing the workpiece when present. When the resisting member lowers the elasticity of the engaging portion causes it to move away from the bearing plate, thus releasing the workpiece when present.
Abstract:
A waste collection device configured to remove magnetically-sensitive particles from the air includes a main body, a collection mechanism, an air inlet mechanism, an air exhaust mechanism, and a discharge mechanism. The main body includes a cover, an electric controller, a partition, and a cavity. The partition divides the cavity into a first cavity and a second cavity. The collection mechanism includes a plurality of dust deposition portions received in the first and second cavities. Each dust deposition portion is electrically powered and includes a plurality of dust deposition plates. The air inlet mechanism includes a first wind shield coupled to the first cavity and a second wind shield coupled to the second cavity.
Abstract:
A rotary driving mechanism includes a support stand, an air feeding assembly, and a driver. The air feeding assembly includes a bearing base, a rotating member, two first ventilating joints, and two second ventilating joints. The bearing base is coupled to the support stand and defines an inner circular surface. The rotating member is rotatably received in the bearing base and resists the inner circular surface. The rotating member defines two circular grooves at an outer periphery thereof and two channels therein. Each circular groove is in fluid communication with one of the channels. The first ventilating joints are coupled to the bearing base and respectively in fluid communication with the circular grooves. The second ventilating joints are coupled to the rotating member and respectively in communication with the channels. The driver is coupled to the rotating member and in communication with the second ventilating joints.
Abstract:
A detecting device for detecting damage to a blade includes a transmission mechanism and a conducting mechanism engaged with the transmission mechanism. The transmission mechanism includes a transmission member, a sliding member coupled to the transmission member, and a support base. The conducting mechanism includes a contacting member and a cable. The transmission member includes a pressing portion and a threaded rod connected to the pressing portion. The blade resists against the pressing portion to move the threaded rod toward the sliding member. The sliding member slidingly cooperates with the support base and presses against the contacting member, and the cable can transmit an electrical signal when the blade is in non-operative state.
Abstract:
A shock absorber includes a push rod, a first piston, a cylinder, a piston rod, a second piston, and a third piston. The cylinder and the first piston cooperatively define a first oil cavity. The second piston, the first piston, and the cylinder cooperatively define a second oil cavity. The third piston and the cylinder cooperatively define a gas cavity. The first piston is configured to urge the hydraulic oil of the second oil cavity to flow into the first oil cavity and the third oil cavity in event the push rod is pushed. The third piston is configured to compress the gas in the gas cavity in event the third piston is urged toward the gas cavity, thereby creating a damping effect.
Abstract:
A processing device includes a mounting base, a cutter holder, and a brake. The brake includes a driving member, a resisting member, and an elastic member. The driving member includes a main body and a driving shaft movably placed in the main body. The driving shaft is driven to move in a straight line by the main body. One end of the driving shaft is movably coupled to the cutter holder, and another end of the driving shaft is coupled to the resisting member. The elastic member is positioned between the main body and the resisting member. The driving shaft is configured to move toward one side of the driving member adjacent to the elastic member under an elastic restoring force of the elastic member, whereby the cutter holder moves with the driving shaft toward one end of the driving member adjacent to the elastic member.
Abstract:
A tool clamping device for holding a cutting tool includes a holder having a holding cavity, a lock nut engaged with the holder, and a collet. The collet includes a collet body and a nut mounting part separated from the collet body by an annular concave part. The collet is tapered and has an axle hole in a central portion thereof, and the axle hole running through the collet body, the annular concave part, and the nut mounting part. The collet further includes a plurality of slots extending along an axial direction of the collet. The collet has an inner wall with a plurality of grooves defined therein. A collet is also provided.
Abstract:
The present disclosure provides a machining equipment which includes a seat, a plurality of electrodes, and a machining assembly assembled on the seat. The machining assembly includes a pole mounted on the seat, a machining tool mounted on the pole, and two protrusions formed on the pole. The pole defines a channel. Each protrusion defines an opening communicated with the channel. The two openings of the two protrusions face the machining tool.
Abstract:
A fixture includes a housing and a gas valve. The housing defines a receiving chamber and a suction hole communicating with the receiving chamber on an end. The gas valve includes a valve body and a piston. The valve body partially resists an inner surface of the receiving chamber to divide the receiving chamber. The valve body defines a first channel, and a first and second through holes respectively communicating with the first channel. The piston is movably received in the first channel, and capable of being pushed to lead the first connecting hole to communicate with the second through hole by gas flowing into the hole, and block a communication between the first connecting hole and the second through hole by gas flowing into the first channel.
Abstract:
A press mechanism includes a driving mechanism, a connecting plate connected to the driving mechanism, an installation plate, and a press assembly. The press assembly includes a base defining at least one first resisting groove, at least one first press block and at least one second press block positioned on the base. The first press block includes at least one first elastic member and a first connecting block defining at least one second resisting groove. A predetermined distance is defined between the first connecting block and the base, and the first elastic member is received in the first resisting groove and the second resisting groove.
