When positioning plungers of different sizes, the bolts need to be disassembled and then reinstalled, which takes a long time and is not convenient enough, reducing the processing efficiency. However, the existing positioning tooling for large plunger processing does not have a component for conveniently positioning plungers of different sizes. Therefore, a positioning tooling for large plunger processing is specifically proposed to solve the above problems. Content of the Utility Model

The positioning tooling for large plunger processing is a special tool used to fix and position the plunger during the processing to ensure processing accuracy and improve production efficiency.

When positioning plungers of different sizes, the bolts need to be disassembled and then reinstalled, which takes a long time and is not convenient enough, reducing the processing efficiency.

The surface of the extrusion control plate is in contact with the surface of the moving extrusion column. The top of the extrusion control plate penetrates through the adjusting shell and extends to the outside of the inner cavity of the adjusting shell. By setting the moving extrusion column and the extrusion control plate, when the extrusion control plate moves, it can generate an extrusion force on the moving extrusion column, and the moving extrusion column subjected to the extrusion force can drive the adjusting block to move.

[0007] Preferably, a limiting rod used in cooperation with the extrusion control plate is fixedly connected to the inner cavity of the adjusting shell.

Usually, the positioning tooling positions the plunger by adjusting the position of the clamping member with bolts. When positioning plungers of different sizes, the bolts need to be disassembled and then reinstalled, which takes a long time and is not convenient enough, reducing the machining efficiency. However, the positioning tooling used in the existing large-sized plunger machining does not have a component for conveniently positioning plungers of different sizes.

[0021] As Figures 1 to 4 shown, a positioning tool for large plunger processing provided by the embodiment of the present utility model includes a base bracket 1 and a rotating shell 2. The bottom of the rotating shell 2 is fixedly connected to the top of the base bracket 1. A rotating block 3 is movably connected to the inner cavity of the rotating shell 2.

A limit top ring 6 is arranged on the top of the limit bottom ring 5. An adjustment shell 7 is fixedly connected to the front side of the limit top ring 6. An adjustment frame 8 is movably connected to the surface of the adjustment shell 7. The bottom of the adjustment frame 8 is fixedly connected to the top of the rotating plate 4. An adjustment device 9 is arranged in the inner cavity of the adjustment shell 7. A positioning device 10 is arranged on the top of the base bracket 1.

[0022] Referring to Figure 4 , the adjustment device 9 includes two adjustment blocks 901. The opposite sides of the two adjustment blocks 901 both penetrate through the adjustment shell 7 and extend to the outside of the inner cavity of the adjustment shell 7. Two moving frames 902 are fixedly connected to the opposite sides of the two adjustment shells 7. Four moving clamping blocks 903 used in cooperation with the moving frames 902 are fixedly connected to the bottom of the inner cavity of the adjustment shell 7. The surface of the moving clamping block 903 is movably connected to the inner cavity of the moving frame 902. A spring 904 is fixedly connected to the opposite sides of the two adjustment blocks 901.

[0023] Adopting the above solution: By setting the adjusting device 9, when the limiting top ring 6 needs to move to an appropriate height according to the size of the plunger, the adjusting device 9 has an adjusting effect on the position of the limiting top ring 6.

[0024] Reference Figure 4 , a moving extrusion column 11 is fixedly connected to the surface of the adjusting block 901, and an extrusion control plate 12 that cooperates with the moving extrusion column 11 is movably connected to the inner cavity of the adjusting shell 7. The surface of the extrusion control plate 12 is in contact with the surface of the moving extrusion column 11, and the top of the extrusion control plate 12 penetrates through the adjusting shell 7 and extends to the outside of the inner cavity of the adjusting shell 7.

[0025] Adopting the above solution: By setting the moving extrusion column 11 and the extrusion control plate 12, when the extrusion control plate 12 moves, it can generate an extrusion force on the moving extrusion column 11, and the moving extrusion column 11 subjected to the extrusion force can drive the adjusting block 901 to move.

[0026] Reference Figure 4 , a limiting rod 13 that cooperates with the extrusion control plate 12 is fixedly connected to the inner cavity of the adjusting shell 7, and the surface of the limiting rod 13 is movably connected to the inner cavity of the extrusion control plate 12.

[0027] Adopting the above solution: By setting the limiting rod 13, pulling the extrusion control plate 12 will drive the extrusion control plate 12 to move along the surface of the limiting rod 13, and the limiting rod 13 has a limiting effect on the moving position of the extrusion control plate 12.

[0028] Reference Figure 3 , an adjusting groove 14 that cooperates with the adjusting block 901 is formed in the inner cavity of the adjusting frame 8. The surface of the adjusting block 901 is in contact with the inner cavity of the adjusting groove 14. The number of the adjusting grooves 14 is several and they are evenly distributed in the inner cavity of the adjusting frame 8.

[0029] Adopting the above solution: By setting the adjusting groove 14, when the adjusting shell 7 moves to an appropriate position and the extrusion control plate 12 is released, the restoring force generated by the spring 904 restoring its shape will drive the adjusting block 901 to snap into the inner cavity of the adjusting groove 14. The cooperation between the adjusting block 901 and the adjusting groove 14 has a limiting effect on the position of the adjusting shell 7.

[0030] Reference Figure 3 , a sliding frame 15 is fixedly connected to the surface of the adjusting shell 7, and two sliding holes 16 that cooperate with the sliding frame 15 are formed in the surface of the adjusting frame 8. The surface of the sliding frame 15 is movably connected to the inner cavity of the sliding hole 16.

[0031] Adopting the above solution: By setting the sliding frame 15 and the sliding holes 16, when the adjusting shell 7 moves, it will drive the sliding frame 15 to move along the inner cavity of the sliding holes 16. The cooperation between the sliding frame 15 and the sliding holes 16 has a limiting effect on the moving position of the adjusting shell 7.

[0032] Reference Figure 2 , the positioning device 10 includes a positioning plate 1001. A stable housing 1002 that cooperates with the positioning plate 1001 is fixedly connected to the top of the base bracket 1. The surface of the positioning plate 1001 is movably connected to the inner cavity of the stable housing 1002. A compression spring 1003 is fixedly connected to the surface of the positioning plate 1001, and the surface of the compression spring 1003 is fixedly connected to the surface of the stable housing 1002.

[0033] With the above solution: By setting the positioning device 10, when the adjusting housing 7 moves, it will drive the sliding frame 15 to move along the inner cavity of the sliding hole 16. The cooperation between the sliding frame 15 and the sliding hole 16 has a limiting effect on the moving position of the adjusting housing 7.

[0034] The working principle of the present utility model:

[0035] During use, when the positioning tooling for large plunger machining needs to conveniently position plungers of different sizes, first, the user places the plunger on the top of the limit bottom ring 5, and then pulls the extrusion control plate 12 forward, driving the extrusion control plate 12 to move along the surface of the limit rod 13. When the extrusion control plate 12 moves, the extrusion force generated on the two moving extrusion columns 11 will drive the two moving extrusion columns 11 to move towards the approaching side. When the moving extrusion columns 11 move, they will drive the two adjusting blocks 901 to move towards the approaching side. When the adjusting blocks 901 move, they will drive the moving frame 902 to move along the surface of the moving clamping block 903. At the same time, the extrusion force generated by the movement of the adjusting blocks 901 will cause the spring 904 to undergo elastic deformation. When the adjusting blocks 901 completely move into the inner cavity of the adjusting shell 7, pull the adjusting shell 7 towards the plunger, driving the sliding frame 15 to move along the inner cavity of the sliding hole 16, and at the same time driving the limit top ring 6 to move towards the plunger. When the bottom of the limit top ring 6 is in close contact with the surface of the plunger, release the extrusion control plate 12. The restoring force generated when the spring 904 resumes its shape will drive the adjusting blocks 901 to snap into the inner cavity of the adjusting groove 14. The combined use of the adjusting blocks 901 and the adjusting groove 14 restricts the position of the adjusting shell 7, and the combined use of the limit bottom ring 5 and the limit top ring 6 restricts the position of the plunger. Then, the positioning plate 1001 can be pulled to the right, driving the positioning plate 1001 to move along the inner cavity of the stable shell 1002. At the same time, the extrusion force generated by the movement of the positioning plate 1001 will cause the compression spring 1003 to undergo elastic deformation. When the positioning plate 1001 disengages from the positioning groove 1004 and the inner cavity of the rotating shell 2, the rotating plate 4 can be rotated to adjust the plunger to an angle convenient for machining. Then, release the positioning plate 1001, and the restoring force generated when the compression spring 1003 resumes its shape will drive the positioning plate 1001 to snap into the inner cavity of the positioning groove 1004. The combined use of the positioning plate 1001 and the positioning groove 1004 restricts the angular position of the rotating block 3 and the plunger, and machining can be carried out. At this time, the positioning tooling for large plunger machining has completed convenient positioning of plungers of different sizes.

[0036] To sum up: For this positioning tooling for large plunger machining, through the combined use of the adjustment device 9, the adjustment, the moving frame 902, the moving clamping block 903, and the spring 904, it solves the problem that during the existing large plunger machining process, it is necessary to ensure that the dimensional accuracy, surface quality, and mechanical properties of the plunger meet the design requirements. The positioning tooling for large plunger machining is a special tool used to fix and position the plunger during the machining process to ensure machining accuracy and improve production efficiency. Usually, the positioning tooling positions the plunger by adjusting the position of the clamping parts with bolts. When positioning plungers of different sizes, the bolts need to be disassembled and then reinstalled, which takes a long time and is not convenient enough, reducing the machining efficiency. However, the existing positioning tooling for large plunger machining does not have components for conveniently positioning plungers of different sizes.
