[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0019] according to Figure 1 、 2 As shown in Figures 3 and 4, this embodiment proposes a machine tool protection safety grating sensor structure that can be stably installed, including a grating sensor body 1, an assembly block 2 and a fixing rod 3, the top of the grating sensor body 1 is fixedly connected to the assembly block 2, one side of the grating sensor body 1 is provided with a fixing rod 3, the top and bottom ends of the fixing rod 3 are symmetrically provided with a clamp 4, one end of the clamp 4 is fixedly connected to one side of the grating sensor body 1, the bottom end of the grating sensor body 1 is provided with a connecting component 5, and the top end of the grating sensor body 1 is provided with a fixing component 6. When in use, the device is fixed to the machine tool through the connecting component 5, and then the grating sensor body 1 and the fixing rod 3 are connected as a whole through the clamp 4, wherein the fixing component 6 at the top of the fixing rod 3 can clamp the assembly block 2 on the top of the grating sensor body 1 to make the connection between the grating sensor body 1 and the fixing rod 3 more stable.

[0020] The fixing assembly 6 includes a fixing plate 7, a sliding groove 8, a No. 1 splint 9, a sliding rail 12, a No. 2 splint 13 and a rotating rod 14. The sliding grooves 8 are symmetrically provided on both sides of the fixing plate 7. The interior of the sliding groove 8 is slidingly connected to the No. 1 splint 9. The sliding rails 12 are symmetrically provided in the middle of the fixing plate 7. The two ends of the sliding rails 12 are symmetrically slidingly connected to the No. 2 splint 13. The No. 1 splint 9 is hinged to the No. 2 splint 13 through the rotating rod 14.

[0021] A support frame 10 is fixedly connected to the middle of the fixed plate 7, and a bidirectional screw rod 11 is rotatably connected inside the support frame 10. Both ends of the bidirectional screw rod 11 pass through the top of the No. 1 splint 9 and are threadedly connected thereto.

[0022] When the two first clamping plates 9 are close to each other, the two second clamping plates 13 are pulled close to each other, and the second clamping plates 13 clamp the other two sides of the assembly block 2, thereby improving the clamping effect of the fixing assembly 6 on the assembly block 2.

[0023] A crossbeam is fixedly connected between a group of No. 2 plywood 13, and a two-way telescopic rod 15 is fixedly connected between the two crossbeams. Springs 16 are symmetrically sleeved on both ends of the two-way telescopic rod 15. When the two groups of No. 2 plywood 13 approach each other, the two-way telescopic rod 15 and the spring 16 are in a compressed state. When the two No. 1 plywood 9 move away from each other, the No. 1 plywood 9 no longer applies pressure to the No. 2 plywood 13 through the rotating rod 14. The elastic force generated by the spring 16 cooperates with the two-way telescopic rod 15 to drive the No. 2 plywood 13 to reset.

[0024] The interior of the clamp 4 is provided with an arc-shaped groove matching the fixing rod 3, and connecting bolts are symmetrically penetrated at both ends of the clamp 4, and nuts are threadedly connected at both ends of the connecting bolts. Extension blocks are symmetrically provided at the top and bottom of one side of the grating sensor body 1. When the fixing component 6 clamps the assembly block 2, the two sets of clamps are respectively attached to the top and bottom ends of the fixing rod 3, wherein one end of the clamp clamps the extension block, and the two connecting bolts are respectively passed through the two ends of the clamp, and one of the connecting bolts also passes through the interior of the extension block. Then, nuts are tightened at both ends of the two connecting bolts to connect the fixing rod 3 and the grating sensor body 1 as one.

[0025] The number of the grating sensor bodies 1 is set to two, and a group of infrared transmitters and infrared receivers are respectively installed on one side of the two grating sensor bodies 1, and the positions of the two groups of infrared transmitters and infrared receivers are parallel to each other. The infrared transmitter emits infrared light beams or laser beams, which form a dense grating or light curtain in space. The infrared light beams are transmitted from the transmitter to the receiver to form a complete light beam path. This path is the area around the machine tool that needs to be protected. The receiver continuously receives and monitors the status of the light beam. If the light beam is blocked or interrupted by any object such as the operator's hand, tool or workpiece, the receiver will immediately sense this change. Once the receiver detects the interruption or obstruction of the light beam, it will immediately generate a safety signal, which will be sent to the safety control system of the machine tool or other related equipment. After receiving the safety signal, the safety control system of the machine tool will immediately trigger corresponding safety measures, such as stopping the movement of the machine tool, reducing the operating speed or issuing an alarm, etc., to prevent accidental injury.

[0026] The connecting assembly 5 includes a rotating arm 17, a rotating shaft 18, a damping sleeve 19 and a connecting seat 20. The bottom end of the fixed rod 3 is fixedly connected to the rotating arm 17, and one end of the rotating arm 17 is hinged to the rotating shaft 18 through the damping sleeve 19. The bottom end of the rotating shaft 18 is fixedly connected to the connecting seat 20. The mounting hole on the connecting seat 20 is aligned with the mounting hole on the machine tool. A fixing bolt is inserted into the inside of the mounting hole. The fixing bolt passes through the connecting seat 20 and is screwed into the inside of the machine tool to connect the connecting seat 20 to the machine tool as a whole. One end of the rotating arm 17 can rotate around the rotating shaft 18, and the other end of the rotating arm 17 is connected to the fixed rod 3, and the fixed rod 3 is connected to the grating sensor body 1. The position of the grating sensor body 1 can be adjusted. The damping sleeve 19 can increase the friction between the rotating shaft 18 and the rotating arm 17 to prevent relative movement between the rotating shaft 18 and the rotating arm 17, thereby maintaining a fastened state and locking the position of the grating sensor body 1.

[0027] The grating sensor fits the assembly block 2 on the top of the grating sensor body 1 to the bottom of the fixing component 6, and screws the bidirectional screw rod 11 to rotate inside the support frame 10. The bidirectional screw rod 11 is threadedly matched with the No. 1 clamping plate 9, and the slide groove 8 limits the movement trajectory of the No. 1 clamping plate 9 to drive the two No. 1 clamping plates 9 to move in a straight line along the slide groove 8, so that the two No. 1 clamping plates 9 approach each other to clamp the two sides of the assembly block 2, thereby strengthening the connection between the grating sensor body 1 and the fixing rod 3. In the process of the two No. 1 clamping plates 9 approaching each other, a group of No. 2 clamping plates 13 are pulled closer to each other through the rotating rod 14, and the No. 2 clamping plates 13 clamp the other two sides of the assembly block 2, thereby improving the clamping effect of the fixing component 6 on the assembly block 2, thereby making the connection between the grating sensor body 1 and the fixing rod 3 more stable.
