[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 4 In this embodiment, an intelligent wire-broken protection lock for an electric spark wire cutting machine includes a wire cutting machine body 1 and a support arm 2 arranged on the wire cutting machine body 1. Two limit plates 5 are fixedly connected to the right side of the support arm 2.

[0024] A mounting plate 3 is placed between the two limit plates 5. An infrared sensor 4 is fixedly installed on the left side of the mounting plate 3, with one end passing through the mounting plate 3 and extending to the right side thereof. Two clamping plates 7 are fixedly connected to the inside of the support arm 2. Two card slots 8 are opened on the left side of the mounting plate 3. The two clamping plates 7 extend to the inside of the two card slots 8 respectively. The outer peripheral walls of the two clamping plates 7 are fixedly covered with rubber rings 6.

[0025] The mounting plate 3 and the support arm 2 are in close contact with each other, the rubber ring 6 is a rectangular ring, and the rubber ring 6 and the slot 8 are in close contact with each other.

[0026] It should be noted that the infrared sensor 4 is a conventional device known to the public in the prior art, and its specific structure and working principle will not be described in detail herein.

[0027] Specifically, the infrared sensor 4 is fixedly installed on the mounting plate 3, and the mounting plate 3 is pushed so that the mounting plate 3 and the support arm 2 fit together. The card plate 7 is inserted into the card slot 8 to restrict the mounting plate 3. The card plate 7 is supported by the fit between the rubber ring 6 and the card slot 8. Under the action of the infrared sensor 4, the electrode wire is monitored and protected.

[0028] In this embodiment, a fixing assembly is provided between the two limit plates 5, and the fixing assembly includes two baffles 17. The two baffles 17 are respectively placed on the opposite side surfaces of the two limit plates 5. The opposite side surfaces of the two limit plates 5 are each provided with an installation groove 9. Telescopic rods 16 are fixedly installed inside the two installation grooves 9. The two telescopic rods 16 are respectively fixedly connected to the two baffles 17. The outer peripheral walls of the two telescopic rods 16 are each provided with springs 15 respectively fixedly connected to the installation groove 9 and the baffles 17. A placement groove 11 is provided on the side of the two limit plates 5 away from the installation plate 3.

[0029] Among them, the left sides of the two baffles 17 are both in contact with the right side of the mounting plate 3, and the telescopic rod 16 is composed of a sleeve and a moving rod. One end of the moving rod passes through and extends to the interior of the sleeve, and the outer side of the moving rod is fixedly connected to a limiting block located inside the sleeve, and a through hole adapted to the moving rod is opened on one side of the sleeve.

[0030] Specifically, the baffle 17 moves, squeezing the telescopic rod 16 and the spring 15, causing the telescopic rod 16 and the spring 15 to shrink, and the mounting plate 3 and the support arm 2 to fit together. The elasticity of the spring 15 pushes the baffle 17 to reset, and the baffle 17 and the mounting plate 3 fit together to fix the mounting plate 3.

[0031] In this embodiment, a driving assembly is provided between the two limit plates 5, and the driving assembly includes two pull plates 10, which are respectively placed inside the two placement grooves 11. Two connecting holes 13 are opened inside the two limit plates 5, and the opposite sides of the two pull plates 10 are fixedly connected with two moving rods 14 with one end passing through the connecting hole 13 and extending to the baffle 17. The outer peripheral walls of the four moving rods 14 are fixedly covered with rubber rings 12.

[0032] The moving rod 14 and the connecting hole 13 are clearance-fitted, the rubber ring 12 and the connecting hole 13 are in close contact, and the four moving rods 14 are respectively located on the left side and the right side of the two springs 15 .

[0033] Specifically, the pull plate 10 is pulled, so that the pull plate 10 drives the moving rod 14 to move, and the moving rod 14 drives the baffle 17 to move. The baffle 17 is supported by the clearance fit between the connecting hole 13 and the moving rod 14, thereby improving the stability of the baffle 17. The moving rod 14 is supported by the fit between the rubber ring 12 and the connecting hole 13, thereby improving the stability of the moving rod 14.

[0034] The working principle of the above embodiment is:

[0035] The elasticity of the spring 15 pushes the baffle 17 to reset, and the baffle 17 and the mounting plate 3 fit together to fix the mounting plate 3, thereby protecting the electrode wire.
