At this time, disassembly is easy to pinch the fingers, which reduces the practicality of the device. At the same time, the pressing method of disassembly is cumbersome.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a jig for processing metal parts for engineering machinery, including a processing chassis and a push block disposed on one side of the processing chassis. A clamping mechanism is provided on one side of the push block, and the clamping mechanism is used to clamp and fix the material and to quickly disassemble it.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0025] Please see Figure 1 - Figure 3This utility model provides a technical solution: a jig for processing metal parts for engineering machinery, including a processing chassis 1, and a push block 2 disposed on one side of the processing chassis 1. A clamping mechanism is provided on one side of the push block 2, which is used to clamp and fix materials and for quick disassembly. The clamping mechanism includes a first limiting component 3 and a second limiting component 4. The first limiting component 3 includes a first clamping sleeve 301, which is disposed on the outer side of one end of the push block 2. A first connecting block 303 is fixedly connected to one side of the push block 2. The first clamping sleeve 301 is sleeved on the outer side of the first connecting block 303, and both ends of the first connecting block 303 are fixed on the outer side. A clamping sleeve 304 is connected, and a locking arm 305 is rotatably connected to the inner side of the top end of the clamping sleeve 304. A magnetic sheet 306 is fixedly connected to the upper surface of the locking arm 305. Limiting posts 302 are fixedly connected to the inner sides of both ends of the first clamping sleeve 301. A first sliding post 308 is slidably connected to the inner side of the top end of the first clamping sleeve 301. The end of the first sliding post 308 is made of magnetic material. A first spring 309 is fixedly connected to the outer side of the top end of the first clamping sleeve 301. The outer side of the end of the first spring 309 is fixedly connected to the inner side of one end of the first sliding post 308. A rubber sheet 307 is fixedly connected to the outer side of one end of the locking arm 305.

[0026] In this embodiment, when the user needs to disassemble the first clamping sleeve 301, they can first press the first sliding post 308 and simultaneously compress the first spring 309. The first sliding post 308 slides into the inner side of the first clamping sleeve 301. At this time, the magnetic material on the outer side of the end of the first sliding post 308 contacts the locking arm 305. Then, the pressure on the first sliding post 308 is released, and the first spring 309 releases its elastic potential energy, causing the first sliding post 308 to rise vertically. At this time, the end of the first sliding post 308 is magnetically connected to the magnetic sheet 306, causing the locking arm 305 to rotate to a certain extent. When the locking arm 305 rotates upward, the opening in the middle of the clamping sleeve 304 opens. At this time, the interface pulls out the first clamping sleeve 301 and pulls out the limiting post 302 from the middle of the clamping sleeve 304. When the first clamping sleeve 301 needs to be installed, simply put the first clamping sleeve 301 on the outside of the first connecting block 303. When the limiting post 302 abuts against the inclined structure on one side of the locking arm 305, it pushes the locking arm 305 to rotate upward. When the limiting post 302 moves to the inner side of the middle of the clamping sleeve 304, the locking arm 305 rotates downward under the action of gravity, closing the opening in the middle of the clamping sleeve 304. At the same time, the magnetic sheet 306 can limit the clamping sleeve 304, and the film 307 reduces the direct contact between the limiting post 302 and the locking arm 305, increasing the service life. Example

[0027] like Figure 4 - Figure 5As shown, the second limiting component 4 includes a second connecting block 401, which is fixedly connected to one side of the push block 2. A locking member 402 is fixedly connected to both sides of the second connecting block 401. A second clamping sleeve 403 is sleeved on the outer side of the second connecting block 401. A second sliding post 404 is slidably connected to the inner side of the top of the second clamping sleeve 403. A second spring 406 is fixedly connected to the upper surface of the second clamping sleeve 403. The outer side of the end of the second spring 406 is fixedly connected to the inner side of one end of the second sliding post 404. A handle 405 is fixedly connected to the outer side of the top of the second sliding post 404. A plurality of third springs 407 are fixedly connected to the outer side of one end of the second connecting block 401. A top plate 408 is fixedly connected to the outer side of the end of each third spring 407.

[0028] In this embodiment, the end of the second clamping sleeve 403 presses against the top plate 408 and stores elastic potential energy in the third spring 407. The user can pull the handle 405 upward, thereby driving the second sliding column 404 to move vertically upward, while stretching the second spring 406, so that the end of the second sliding column 404 disengages from the inclined structure on one side of the locking member 402. The elastic potential energy of the third spring 407 is released, pushing the top plate 408 and the second clamping sleeve 403, thereby directly popping out the second clamping sleeve 403. When the second clamping sleeve 403 is installed, the inclined structure on one side of the second sliding column 404 contacts the inclined structure on one side of the locking member 402 until the second sliding column 404 moves to the vertical structure on one side of the locking member 402.

[0029] Working principle: When the user needs to disassemble the first clamping sleeve 301, they can first press the first sliding post 308 and simultaneously compress the first spring 309. The first sliding post 308 slides into the inner side of the first clamping sleeve 301. At this time, the magnetic material on the outer side of the end of the first sliding post 308 contacts the locking arm 305. Then, the pressure on the first sliding post 308 is released, and the first spring 309 releases its elastic potential energy, causing the first sliding post 308 to rise vertically. At this time, the end of the first sliding post 308 is magnetically connected to the magnetic sheet 306, causing the locking arm 305 to rotate to a certain extent. After the locking arm 305 rotates upward, the clamping sleeve 301... The opening in the middle of 04 is open, at which point the first clamping sleeve 301 is pulled out of the interface, and the limiting post 302 is pulled out from the middle of the clamping sleeve 304. When the first clamping sleeve 301 needs to be installed, it is only necessary to put the first clamping sleeve 301 on the outside of the first connecting block 303. When the limiting post 302 abuts against the inclined structure on one side of the locking arm 305, the locking arm 305 is pushed to rotate upward. When the limiting post 302 moves to the inner side of the middle of the clamping sleeve 304, the locking arm 305 rotates downward under the action of gravity, closing the opening in the middle of the clamping sleeve 304. At the same time, the magnetic sheet 306 can limit the clamping sleeve 304, and the film 307 reduces the limiting post. Direct contact between 302 and the locking arm 305 increases lifespan. The end of the second clamping sleeve 403 presses against the top plate 408 and stores elastic potential energy in the third spring 407. The user can pull the handle 405 upward, thereby causing the second sliding column 404 to move vertically upward, while stretching the second spring 406, causing the end of the second sliding column 404 to disengage from the inclined structure on one side of the locking member 402. The elastic potential energy of the third spring 407 is released, pushing the top plate 408 and the second clamping sleeve 403, thus allowing the second clamping sleeve 403 to be ejected directly. When the second clamping sleeve 403 is installed, the inclined structure on one side of the second sliding column 404... The clamping head is replaced by a simple pulling action by the operator through the clamping mechanism. This greatly reduces the difficulty and labor intensity of the operator's work. The pull-type quick replacement allows the operator to complete the operation from a certain distance from the equipment. By setting a safe distance for the hand, the operator can effectively avoid finger injuries during replacement. Furthermore, the quick replacement achieved through the pulling operation can significantly reduce the time spent on the replacement process, allowing the equipment to return to the processing state more quickly and effectively improving the utilization rate of the equipment.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
