Abstract: The disclosure is related to a clamp-type measuring device includes a clamp and an interval measuring module. The clamp includes a guiding rail and two holding arm. Each of holding arms includes a guide part, a connecting part, and a clamping part. The guide part is movably furnished on the guiding rail. Both ends of the connecting part are respectively connected to the guide part and the clamping part. The interval measuring module includes a first measuring element and a second measuring element. The first measuring element and the second measuring element are furnished on the two connecting parts respectively. The first measuring element and the second measuring element are slidable through the two guide parts respectively in order to measure an interval between the two clamping parts. In addition, the disclosure is also related to a measuring method of the clamp-type measuring device.

Abstract: A power and signal transmission device for a spindle of a machine tool is provided. The power and signal transmission device includes a spindle fixing portion, a shaft rotating portion, a power transmission component and a signal transmission component. The spindle fixing portion is provided with a power input end, a primary side power induction coil, a secondary side signal induction coil and at least one signal output end. The shaft rotating portion is provided with a joining end surface for bonding to a holder, a secondary side power induction coil and a primary side signal induction coil, and is rotatable with respect to the spindle fixing portion. The power transmission component transmits an electrical energy from the power input end. The signal transmission component transmits a holder signal to the signal output end. Each of the power and signal transmission components includes at least one elastic pogo pin.

Abstract: A clamping and positioning device includes a base, a rotary member, a moving assembly and an elastic member. The rotary member is rotatably disposed on the base and includes a stopping surface facing the base. The moving assembly includes a moving member movably disposed on the base to have a first and a second position. When being at the first position, the moving member is pressed against the rotary member to allow the stopping surface to apply a normal force to the base; when being at the second position, a gap is formed between the moving member and the rotary member so the normal force applied by the stopping surface of the rotary member is released from the base. The elastic member has two ends connected to the base and the moving member, respectively. The elastic member normally causes the moving member to be at the first position.
