Detailed implementation mode

[0025] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will detail this application with reference to the drawings and in combination with the embodiments.

[0026] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0027] As Figures 1-4 shown, this application provides a new type of cylinder block processing fixture, including a workbench 1. Four legs 4 are fixedly connected to the bottom of the workbench 1. A clamping mechanism 2 is arranged on the workbench 1. The clamping mechanism 2 includes a moving block slidably connected to the workbench 1. A rotating connection shaft 21 is rotatably connected to the moving block. One end of the rotating connection shaft 21 is fixedly connected to a placement table 22. Four connecting pieces 23 are fixedly connected to the outside of the placement table 22. The inner wall of the connecting piece 23 is threadedly connected to a bolt rod 24. One end of the bolt rod 24 is rotatably connected to a limiting block 26. The end of the bolt rod 24 away from the limiting block 26 is fixedly connected to a rotating block 25. A plurality of rubber blocks 27 are fixedly connected to the limiting block 26. The cylinder block is clamped and limited by arranging the bolt rod 24 on the placement table 22.

[0028] By turning the rotating block 25, the rotation of the rotating block 25 will drive the bolt rod 24 to rotate on the connecting piece 23, thereby driving the limiting block 26 to move. The four limiting blocks 26 can clamp and limit the four sides of the cylinder block. At the same time, the limiting block 26 can rotate freely by 360 degrees on the bolt rod 24. According to the shape and size of the cylinder block, personnel can conveniently adjust the angle of the limiting block 26 and cooperate with the rubber block 27. The rubber block 27 can fill the gap between the limiting block 26 and the cylinder block to a certain extent, so as to achieve the limit of different cylinder blocks.

[0029] It should be supplemented that reinforcing ribs 28 are fixedly connected to both opposite sides of the connecting piece 23. The other side of the reinforcing rib 28 is fixedly connected to the placing table 22. A plurality of drawers 29 are slidably connected to the workbench 1. The setting of the reinforcing rib 28 can improve the connection stability between the connecting piece 23 and the placing table 22. At the same time, the setting of the drawer 29 can store small parts such as screws removed from the cylinder block and tools in an organized manner.

[0030] As Figure 2 and Figure 4 shown, an adjusting mechanism 3 is provided on the rotating connecting shaft 21. The adjusting mechanism 3 includes a plurality of positioning grooves 309 opened on the rotating connecting shaft 21. A fixed block 301 is fixedly connected to the workbench 1. A plug rod 302 is slidably connected inside the fixed block 301. One end of the plug rod 302 is fixedly connected to a positioning block 307. A spring 304 is sleeved on the plug rod 302. The two ends of the spring 304 are fixedly connected to the plug rod 302 and the fixed block 301 respectively. The size of the positioning block 307 is adapted to the size of the positioning groove 309. The plug rod 302 is inserted into the positioning groove 309 under the elastic force of the spring 304, so as to realize the limit of the rotation angle of the rotating connecting shaft 21. When the positioning block 307 is inserted into different positioning grooves 309, the limit of different rotation angles of the rotating connecting shaft 21 is realized.

[0031] Specifically, a limiting groove 305 is opened on the fixed block 301. A clamping block 306 is slidably connected to the inner wall of the limiting groove 305. The cooperation between the limiting groove 305 and the clamping block 306 can prevent the plug rod 302 from rotating at an angle during the insertion and extraction process. At the same time, in order to make it easier for the positioning block 307 to be inserted into the positioning groove 309, a convex block 308 is fixedly connected to the surface of the positioning block 307. The convex block 308 is a frustum of a pyramid.

[0032] At the same time, the clamping block 306 is fixedly connected to the surface of the plug rod 302. One end of the plug rod 302 away from the positioning block 307 is fixedly connected to a connecting rod 303. A socket block 310 is fixedly connected to the connecting rod 303. The setting of the connecting rod 303 can facilitate personnel to move the positioning block 307 in the case where the space under the workbench 1 is narrow and it is difficult to operate the positioning block 307.

[0033] Working principle: During actual use, when it is necessary to limit and clamp the cylinder block, the operator can place the cylinder block on the placement table 22 and drive the four limit blocks 26 through the bolt rod 24 to clamp the cylinder block, thus achieving the clamping of the cylinder block.

[0034] At the same time, to facilitate the operator to process the surface of the cylinder block, the operator can pull the connecting rod 303 to operate the movement of the positioning block 307. When the positioning block 307 is inserted into different positioning grooves 309, the different rotation angles of the workbench 1 are limited.

[0035] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
