[0002] In order to correct the stability and accuracy of the indexing of the tool rest during operation or indexing, it is necessary to configure a signal acquisition device for the tool rest to monitor its motion state; the conventional structure is to set a mutually matching induction block and an induction switch at the rear of the tool rest spindle, and form a tool rest clutch state determination device through relative or absolute coding forms. This structure requires more parts, occupies a large space, has a complex manufacturing process, and its overall cost is relatively high.

[0003] Therefore, there is a need for a method or device that can solve the above problems now. Summary of the Invention

[0008] The clutch signal acquisition device with this structural form for the tool rest has a simple structure, ingenious design, and reasonable layout. Aiming at the problems existing in the traditional clutch state monitoring and signal acquisition devices during use, it designs a special structure. It designs a set of mechanisms directly connected to the positioning end gear disc, which can directly use the positioning end gear disc on the tool rest to drive the trigger piece to move and trigger two induction switches respectively. Compared with the traditional method, the signal source of this structure is more direct, so the detection effect is more accurate. At the same time, it has a compact structure, small size, does not occupy too much installation space, and its manufacturing process is simple and the manufacturing cost is low.

BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 is the front view of the embodiment of the present invention.

[0010] Figure 2 is the top view of the embodiment of the present invention.

[0011] Figure 3 is the schematic diagram of the movement process of the swing piece in the embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] The following will describe the specific embodiments of the present invention in conjunction with the drawings. As Figure 1 , Figure 2 , Figure 3 shown: A clutch signal acquisition device for a tool rest, which includes a fixed base connected to the tool rest. A bushing 1 is arranged in the middle of the fixed base. A trigger shaft 2 is rotatably connected in the bushing 1. The top end of the trigger shaft 2 is fixedly connected to the center of a trigger piece 3. The signal acquisition device further includes an induction switch bracket 4 also connected to the tool rest. A first induction switch 5 and a second induction switch 6 are symmetrically arranged on the induction switch bracket 4, and the two ends of the trigger piece 3 respectively match the detection positions of the first induction switch 5 and the second induction switch 6.

[0013] The bottom end of the trigger shaft 2 is fixedly connected to a first connection hole 8 on a swing piece 7. A second connection hole 9 is opened at the end of the swing piece 7. A connecting shaft 10 is movably connected in the second connection hole 9, and the connecting shaft 10 is arranged on the top surface of a positioning end gear disc 11.

[0014] The working process of the clutch signal acquisition device for the tool rest in the embodiment of the present invention is as follows: During operation, the positioning end gear disc 11 will make a reciprocating linear motion relative to the tool rest, and the two extreme positions where the positioning end gear disc 11 is located respectively correspond to two states of the clutch. Therefore, this device uses the positioning end gear disc 11 to determine the current state of the clutch.

[0015] When the positioning end gear disk 11 moves linearly, since the connecting shaft 10 provided on its top end is movably inserted into the second connecting hole 9 opened at the end of the swing piece 7, it will drive the swing piece 7 to swing around the center of the first connecting hole 8. Since the swing piece 7 is fixedly connected to the trigger shaft 2 through the first connecting hole 8, when the swing piece 7 swings, it will drive the trigger shaft 2 to rotate along its own axis, and the rotation angle is the swing angle of the swing piece 7;

[0016] When the trigger shaft 2 rotates, the trigger piece 3 at its top end also swings accordingly. When the end of the trigger piece 3 approaches the first induction switch 5, the first induction switch 5 is triggered and sends a signal to the control system, and the control system can then judge the current state of the clutch;

[0017] By the same token, when the positioning end gear disk 11 moves in the reverse direction, it will drive the trigger shaft 2 to rotate in the reverse direction through the swing piece 7, and then drive the trigger piece 3 to swing in the reverse direction. The other end of the trigger piece 3 approaches the second induction switch 6, the second induction switch 6 is triggered and sends a signal to the control system, and the control system can then judge the current state of the clutch.
