DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment 1. In Figure 1 a special disassembly fixture for a feeding screw rod includes a feeding screw rod body 1. A square reduction gearbox 2 is provided at the bottom of the feeding screw rod body 1. A fixed bracket 3 is provided above the square reduction gearbox 2. A chuck support plate 4 is provided at the top of the fixed bracket 3. A special chuck 5 is provided at the top of the chuck support plate 4. A support column 6 is provided at the top of the square reduction gearbox 2. A hydraulic head 7 is provided at the top of the support column 6. An insertion rod 8 is provided at the top of the square reduction gearbox 2.

[0020] The feeding screw rod body 1 is connected to the square reduction gearbox 2 through the insertion rod 8. The fixed bracket 3 is connected to the chuck support plate 4 through a card slot and a limit block. And through the limit of the fixed bracket 3, the positions of the chuck support plate 4 and the special chuck 5 are limited, so that the special chuck 5 fixes the position of the feeding screw rod body 1 through the clamping plate 506. When the hydraulic head 7 presses down to drive the square reduction gearbox 2 to move, the insertion rod 8 can be separated from the feeding screw rod body 1 to complete the disassembly.

[0021] Embodiment 2. In Figure 3 a fixing plate 501 is fixedly installed at the top of the chuck support plate 4. A limit rod 502 is fixedly installed inside the fixing plate 501. A bidirectional threaded rod 503 is rotatably installed inside the fixing plate 501. A threaded block 504 is threadedly connected to the outside of the bidirectional threaded rod 503. A micro motor 505 is fixedly installed outside the fixing plate 501. A clamping plate 506 is fixedly installed outside the threaded block 504.

[0022] The micro motor 505 drives the bidirectional threaded rod 503 to rotate. The threaded block 504 is threadedly connected to the outside of the bidirectional threaded rod 503. The clamping plate 506 is fixedly installed outside the threaded block 504. By adjusting the threaded block 504 through the bidirectional threaded rod 503, the distance between the two clamping plates 506 can be adjusted according to the size of the feeding screw rod body 1, so that the disassembly fixture can be adapted to feeding screw rod bodies 1 of different models. Anti-slip pads are fixedly installed on the opposite sides of the two clamping plates 506. By fitting the anti-slip pads with the outer wall of the feeding screw rod body 1, the clamping plate 506 can be clamped more stably when clamping the feeding screw rod body 1, preventing the feeding screw rod body 1 from falling off from the clamping plate 506.

[0023] In summary, for the special disassembly fixture of the feeding screw, after the feeding screw body 1 passes through the chuck support plate 4 and approaches the clamping plate 506, the micro motor 505 is turned on. The two clamping plates 506 are driven by the bidirectional threaded rod 503 to approach the two feeding screw bodies 1 simultaneously and clamp the feeding screw body 1. The chuck support plate 4 is clamped with the fixed bracket 3. The hydraulic head 7 drives the support column 6 to move downward. After the square reduction gearbox 2 moves downward, the insertion rod 8 disengages from the feeding screw body 1. Then, after the feeding screw body 1 is separated from the clamping plate 506 by the micro motor 505, the disassembly of the feeding screw body 1 can be completed in a simple, efficient and non-damaging way for the accessories, solving the problem that when the feeding screw has been used for a certain period of time and needs to be disassembled, repaired and replaced due to the wear of the feeding screw or the failure of the reduction gearbox, a disassembly tool for the feeding screw that is simple, efficient and does not damage the accessories is required.
