摘要： A grinding wheel changing structure of grinding machines includes a base to which a clamping device, a grinding device, a storage device, a gripping device are mounted thereon. The clamping device clamps workpieces. The grinding device is movable along two axes and includes a grinding wheel and a guard. The grinding wheel is located inside the guard. A lid is pivotably connected to the guard. The storage device has multiple grinding wheels detachably stored therein. The gripping device is located between the grinding device and the storage device. The gripping device is linearly movable and includes a gripping unit which is rotatable. By using the gripping device with its gripping unit to grasp the grinding wheel and shuttle back and forth, rotate between the grinding device and the storage device, to load and unload the grinding wheel.

摘要： The present disclosure provides a spindle structure including a base, a spindle, a sliding member, a restoring mechanism, and a restriction member. The spindle is rotatably received in the base and forms a receiving room. An end of the receiving room is a blind end communicating exterior via a gas channel. The sliding member is slidably received in the receiving room, and two ends thereof are a piston and a driving portion respectively. A gas cavity is defined between the piston and the blind end. The sliding member tends to move toward the blind end due to the restoring mechanism. The restriction member is connected to the driving portion and radially deforms when the sliding member slides so as to fix or to release the tool-holder. The sliding member slides outward when the gas cavity is injected with gas via the gas channel.

摘要： The present disclosure provides a gripper module, including a base, an adapter holder, a collet holder, and an actuator. The base is adapted for an adapter to be detachably disposed thereon. The adapter holder is able to engage and to buckle the adapter. The collet holder is able to engage and to buckle a collet which is installed in the adapter. The actuator is connected to the collet holder. The actuator can pull the collet holder and the collet to move, causing pressing and retraction of the collet by the conical surface between the collet and the adapter. Therefore, sizes of collets may apply to the gripper module with the adapter. By sheathing the adapter, replacement and size alternation of the collets are made easier, and precisions of allocations of the collet and the gripped workpiece are improved.

摘要： A workpiece spindle comprises a spindle, a spindle motor and an actuator. The spindle is dynamically connected to the spindle motor and has a first channel and a second channel connected to the first channel. The first channel is assembled with a lathe center, the actuator is provided with an actuating rod disposed outside the spindle corresponding to the second channel. The workpiece spindle limits rotation of the spindle by displacing the actuating rod of the actuator by a first actuation distance relative to the second channel, and the workpiece spindle drives the lathe center to displace in the first channel by displacing the actuating rod of the actuator by a second actuation distance relative to the second channel. Thereby, machining statuses of the lathe center are integrated for convenient operation, and the lathe center is driven and displaced in the channel to facilitate replacement.

摘要： The present disclosure provides an automatic processing apparatus including a main body, a receiving portion, a working assembly, a workpiece magazine, a setting mechanism, a passivation bucket assembly, and a rotation driving assembly. The receiving portion is adapted for receiving a plurality of workpieces. The setting mechanism takes the workpieces to the receiving portion from the workpiece magazine. The working assembly is adapted for bringing the workpieces to the passivation bucket assembly for processing. The passivation bucket assembly includes a turning table and a plurality of passivation buckets moving when the turning table rotates. The rotation driving assembly drives one of the passivation buckets to rotate. Thereby, automatic processing can be achieved by the apparatus of the present invention, and the efficiency of processing is improved too.
