Description

Technical Field

[0001] The utility model relates to the technical field of chuck disassembly and replacement, and particularly relates to a chuck quick-change assembly with a convenient disassembly function. Background Art

[0002] During the process of tooling processing, automatic welding technology is required. In automatic welding technology, some parts need to be precisely fixed to prevent shaking during the welding process. Therefore, the fixing module in automatic welding is widely used.

[0003] During the fixing operation of automatic welding, the chuck is placed on the chuck base and fixed by a nut. There will be a gap between the nut and the base of the chuck. A threaded hole is drilled at the gap, and a screw is driven into the threaded hole by a thread gun to achieve the effect of threaded fixation. During the disassembly process, only the nut needs to be driven by a thread gun to release the connection between the chuck and the chuck base, and then the disassembly and replacement can be carried out.

[0004] When disassembling the chuck, the disassembly process by removing the thread will be relatively long. The welding process needs to be stopped completely before disassembly. After the thread is removed, the screw is also likely to fall and be lost due to the worker's mistake, further affecting the working efficiency of the overall process. Therefore, there is a problem that the operation of replacing the chuck is relatively troublesome. Summary of the Utility Model

[0005] The purpose of the utility model is to set a detachable replacement structure, which can quickly replace the chuck without using a large number of nuts and improve the overall production efficiency.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a chuck quick-change assembly with a convenient disassembly function, including two symmetrically arranged replacement mechanisms. The replacement mechanism is divided into an upper replacement part and a lower replacement part. The lower replacement part includes a lower replacement base and lower symmetric columns opened on the lower replacement base. The upper replacement part includes an upper replacement base. A symmetric groove body matching the lower symmetric columns is opened on the upper replacement base. A rotating half shaft passes through the upper replacement base. A limiting blocking part is fixedly connected to the lower replacement base. One side of the rotating half shaft abuts against the limiting blocking part. The cross-section in the middle of the rotating half shaft is semicircular. The limiting blocking part and the lower symmetric columns form a limiting blocking groove in a straight line, and the rotating half shaft is clamped in the limiting blocking groove.

[0007] Preferably, one end of the rotating half shaft is rotatably connected to a rotating rod, and a limiting part is fixedly connected to the rotating rod. The limiting part is fixedly combined with the upper replacement base.

[0008] Preferably, a limit fixing groove is provided on the upper replacement base, and a limit nut that cooperates with the limit fixing groove is rotatably connected to the end of the limiting member.

[0009] Preferably, a half-axis groove body is provided on the rotating half-axis. When the rotating half-axis is clamped in the limit blocking groove, the bottom surface of the half-axis groove body is higher than the end of the blocking member.

[0010] Preferably, an upper connection threaded port is provided on the upper replacement base, and a lower connection threaded port communicating with the connection threaded port is provided on the lower replacement base.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. By setting the rotating half-axis structure, the effect of clamping and releasing the clamping state can be achieved through rotation. When installing and disassembling, only the rotating half-axis needs to be rotated, which improves the convenience of installing and replacing the chuck.

[0013] 2. By setting the limit fixing groove, nuts can be added in the limit fixing groove, and fixing is achieved through the installation method of a single nut, which greatly reduces the workload during disassembly and further improves the working efficiency of the automatic welding process.

[0021] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] Refer to Figures 1-3 , two symmetrical replacement mechanisms 1 are provided. Both of the two replacement mechanisms 1 can quickly replace the collet and can replace two collets. The replacement mechanism 1 is divided into an upper replacement part 3 and a lower replacement part 2. Among them, the upper replacement part 3 is the replacement part for fixing the collet, and the lower replacement part 2 is the part of the collet.

[0023] Refer to Figures 1-3 , the lower replacement part 2 includes a lower replacement base 21 and lower symmetrical columns 211 opened on the lower replacement base 21. The upper replacement part 3 includes an upper replacement base 31. A symmetrical groove body 311 matching the lower symmetrical columns 211 is opened on the upper replacement base 31. When the collet is installed, the symmetrical groove body 311 on the upper replacement base 31 cooperates with the lower symmetrical columns 211, and the lower symmetrical columns 211 are inserted into the symmetrical groove body 311 to form a limiting effect.

[0024] Refer to Figures 1-3 , a rotating half shaft 32 passes through the upper replacement base 31. The shape of the rotating half shaft 32 is in the shape of a semi-cylinder. A limiting blocking piece 22 is fixedly connected to the lower replacement base 21. One side of the rotating half shaft 32 abuts against the limiting blocking piece 22. When one end of the semi-circle rotates to one side of the lower blocking piece, a limiting relationship is formed between the rotating half shaft 32 and the limiting blocking piece 22. At this time, the collet cannot be replaced by applying a force in the vertical direction. The cross-section in the middle of the rotating half shaft 32 is semi-circular. The limiting blocking piece 22 and the lower symmetrical columns 211 form a limiting blocking groove 23. The rotating half shaft 32 is clamped in the limiting blocking groove 23, restricting the rotation space of the rotating half shaft 32.

[0025] Refer to Figures 1-3When the locking nut 323 is engaged with the locking nut 324, the locking nut 324 can be locked to the locking nut 324 when the locking nut 323 is engaged with the locking nut 324.

[0026] refer to Figures 1-3 An upper connecting threaded opening 33 is provided on the upper replacement base 31, and a lower connecting threaded opening 24 connected to the connecting threaded opening is provided on the lower replacement base 21. Through the two connecting threaded openings, a single threaded connection is performed after the chuck is successfully replaced, which saves the number of bolts and can enhance the fixing effect of the chuck.

[0027] The working principle of this mechanism is as follows: when replacing the chuck, the bolts in the two connecting threaded openings are screwed, and then the threaded connection effect of the limit nut 323 is released, and the limit piece 322 is rotated to drive the rotating half shaft 32 to rotate circumferentially, so that the semicircular part of the rotating half shaft 32 rotates to a part that does not conflict with the limit blocking piece 22. At this time, the upper replacement part 3 can be disassembled and the chuck part can be replaced. When the chuck is replaced, the upper replacement part 3 and the lower replacement part 2 are stacked so that the upper symmetrical groove body 311 and the lower symmetrical column 211 are mutually engaged, and the rotating half shaft 32 is rotated again, and the semicircular part of the rotating half shaft 32 conflicts with the limit blocking groove 23. The rotating rod 321 is rotated and the limit nut 323 at the end of the limit piece 322 is screwed into the limit fixing groove 312, and the operation of quickly replacing the chuck can be completed.

[0028] The above embodiments are used to further illustrate the present invention, but the present invention is not limited to these specific implementations. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention should be understood to be within the protection scope of the present invention.
