DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] Embodiment one, please refer to Figure 1 - Figure 6 In the embodiments of the present application, a high-precision numerical control machine tool control mechanism comprises a machine tool body 100, a safety door 110 is slidably connected to the outer side of the machine tool body 100, and a driving assembly 200 is arranged on the top of the machine tool body 100. The driving assembly 200 can drive the safety door 110 to automatically open and close. The driving assembly 200 comprises a motor 210 fixedly connected to the machine tool body 100, and the output end of the motor 210 is drivingly connected with a synchronous belt 220. The outer side of the synchronous belt 220 is detachably and fixedly provided with a fixing assembly 300. The fixing assembly 300 and the safety door 110 are provided with a linkage assembly 400 therebetween. The linkage assembly 400 comprises a sliding block 410 slidably connected to the safety door 110. The outer side of the sliding block 410 is fixedly provided with two pin shafts 411. The pin shafts 411 are detachably and fixedly inserted into the fixing assembly 300. The linkage assembly 400 further comprises a winding wheel 420. The outer side of the winding wheel 420 is wound and fixedly provided with a traction rope 421 capable of pulling the sliding block 410 to move. The traction rope 421 is fixedly connected to the sliding block 410. The outer side of the safety door 110 is fixedly provided with a handle assembly 500. The handle assembly 500 can assist the user to manually open the safety door 110.

[0035] Specifically, by installing the fixing assembly 300 on the synchronous belt 220 of the driving assembly 200, the safety door 110 is detachably and movably connected with the fixing assembly 300 through the pin shaft 411, when it is needed to automatically open and close the safety door 110, the pin shaft 411 is connected with the fixing assembly 300, the motor 210 drives the synchronous belt 220 to drive the fixing assembly 300 to move with the pin shaft 411, thereby enabling the safety door 110 to be automatically opened and closed, and by installing the existing travel switch 120 on one side of the fixing assembly 300, when the fixing assembly 300 moves to the position of the travel switch 120 along with the synchronous belt 220, the travel switch 120 can automatically control the motor 210 to stop, thereby achieving the effect that the safety door 110 stops moving after being closed.

[0036] When it is needed to manually open and close the safety door 110 to perform tool setting, the hand-held wheel 530 on the handle assembly 500 is rotated to rotate the shaft rod with the winding wheel 420 to wind the traction rope 421, the traction rope 421 pulls the sliding block 410 to make the pin shaft 411 separate from the fixing assembly 300, so that the safety door 110 separates from the fixing assembly 300, at this time, the safety door 110 can be manually opened and closed, thereby saving the cumbersome work of inputting the automatic opening and closing program of the safety door 110 into the computer system of the machine tool, and preventing the manual opening and closing of the safety door 110 from damaging the motor 210 on the driving assembly 200.

[0037] As shown in Figure 5 In this embodiment, the driving assembly 200 further comprises two supporting seats 230, and a belt wheel two 231 is rotatably arranged between the two supporting seats 230, and a belt wheel one 211 is fixed to the output end of the motor 210, and the belt wheel one 211 and the belt wheel two 231 are both in transmission connection with the synchronous belt 220.

[0038] In this embodiment, the motor 210 drives the belt wheel one 211 at the output end to rotate to drive the synchronous belt 220 to transmit between the belt wheel one 211 and the belt wheel two 231, thereby enabling the synchronous belt 220 to drive the fixing assembly 300 to move with the safety door 110 to perform the opening operation, wherein the synchronous belt 220 is in back-and-forth circulation transmission mode by the forward and reverse rotation of the motor 210 at the output end with the belt wheel one 211, thereby achieving the linear movement of the safety door 110 to the left and right to perform the opening operation.

[0039] As shown in Figure 5 In this embodiment, the fixing assembly 300 comprises a supporting plate 310 supported on the bottom surface of the synchronous belt 220, and a cover plate 311 is detachably fixed to the top surface of the supporting plate 310 through bolts, when the fixing assembly 300 is installed, the supporting plate 310 is first placed below the synchronous belt 220, then the cover plate 311 is placed above the synchronous belt 220, and then the cover plate 311 and the supporting plate 310 are fixed together by using the bolts, so that the fixing assembly 300 is clamped and fixed to the outside of the synchronous belt 220.

[0040] As Figure 5 shown in the embodiment, one end of the supporting plate 310 is provided with two pin holes 312, and one end of the supporting plate 310 is fixed with a connecting block 320. When the synchronous belt 220 moves with the fixed assembly 300 to the position of the travel switch 120, the connecting block 320 on the fixed assembly 300 will actuate the travel switch 120, and then the travel switch 120 controls the motor 210 to stop driving the driving assembly 200 to work, so that the driving assembly 200 stops driving the safety door 110 to move after the safety door 110 is closed. The travel switch 120 is a prior art, and the specific working principle is not described in detail.

[0043] In the embodiment, when the traction rope 421 pulls the sliding block 410 to move away from the fixed assembly 300, the sliding block 410 compresses the return spring 412. When it is needed to insert the pin shaft 411 into the pin hole 312 of the fixed assembly 300 again, the handheld wheel 530 is reversely rotated to make the shaft rod rotate the winding wheel 420 to release the traction rope 421, and the sliding block 410 can be slidably inserted into the pin hole 312 of the fixed assembly 300 again under the elastic force of the return spring 412.

[0044] As Figure 6 shown in the embodiment, the traction rope 421 between the winding wheel 420 and the sliding block 410 is inserted in the safety door 110, and the safety door 110 is provided with a rope groove for accommodating the traction rope 421.

[0045] In the embodiment, the sliding block 410 on the linkage assembly 400 is kept in position after moving.

[0046] As Figure 2 - Figure 4As shown, in the embodiment, the handle assembly 500 includes two support blocks 510 fixedly connected with the safety door 110, a shaft rod rotatably connected between the two support blocks 510, a hand wheel 530 fixedly arranged on the outer side of one end of the shaft rod, a threaded groove 520 arranged on the outer side of one end of the shaft rod, and the threaded groove 520 screw-coupled with the corresponding support block 510, and the threaded groove 520 on one end of the shaft rod fixedly connected with the winding wheel 420.

[0047] In the embodiment, the threaded groove 520 is arranged on one end of the shaft rod, the threaded groove 520 screw-coupled with the support block 510, the hand wheel 530 is rotated to rotate the shaft rod, and the winding wheel 420 on the shaft rod is rotated to wind the traction rope 421, the threaded groove 520 on the shaft rod is screw-coupled with the support block 510, so that the shaft rod is fixed at the rotated position by the self-locking characteristic of the thread after the shaft rod is rotated, the winding wheel 420 is kept at the rotated position after the winding wheel 420 is rotated to wind the traction rope 421, and the sliding block 410 at the other end of the traction rope 421 is kept away from the fixed assembly 300 with the pin shaft 411, a gap is reserved between one end of the hand wheel 530 and the support block 510 in the initial state, the gap meets the requirement that the shaft rod is screw-coupled and moved in position between the two support blocks 510 when the shaft rod is rotated, and the end of the shaft rod away from the threaded groove 520 is slidingly connected with the corresponding support block 510.
