[0027] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to 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.
[0028] Refer to Figure 1 and Figure 5 , a tooling bottom plate 1 is provided, and a placing groove 11 is formed on the tooling bottom plate 1. The silencer can be placed in the placing groove 11. The placing groove 11 is circular and matches the shape of the silencer.
[0029] Refer to Figure 2A fixed structure 2 is provided on the tooling bottom plate 1. The fixed structure 2 can apply force to the surface of the muffler and fix and stabilize the muffler. The fixed structure 2 includes several fixed brackets 21 and a fixed shaft rotatably connected to the fixed bracket 21. The fixed shaft rotates relative to the fixed bracket 21. A first rotating member 22 is fixedly connected to the fixed shaft close to the placement slot 11, and a second rotating member 23 is fixedly connected to the fixed shaft far from the placement slot 11. The fixed structure 2 also includes a fixed contact plate 25. The fixed contact plate 25 contacts the surface of the muffler and matches the surface shape of the muffler. The surface array of the fixed contact plate 25 is provided with a plurality of contact convex strips 251, and the contact convex strips 251 have elastic deformation performance, which increases the pressure of contact with the surface of the muffler, improves the friction force, and prevents damage to the surface of the muffler. A fixed sliding member 12 is provided on the tooling bottom plate 1, and one end of the first rotating member 22 is rotatably connected to a fixed sliding rod 122, and the fixed sliding rod 122 is slidably connected in the fixed sliding port 121. The fixed contact plate 25 is fixedly connected to one end of the fixed sliding rod 122, and the first rotating member 22 can drive the fixed sliding rod 122 to move. The fixed sliding member 12 is provided with a fixed sliding port 121. 21, the fixed sliding rod 122 slides in the fixed sliding mouth 121, and a clearance slot 123 is provided at the top of the fixed sliding member 12. A linkage rod 124 is fixedly connected between the fixed sliding rod 122 and the fixed contact plate 25. The linkage rod 124 is slidably connected in the clearance slot 123. The fixed contact plate 25 is driven to slide along the length direction of the fixed sliding member 12 by the linkage rod 124. The sliding effect of the linkage rod 124 is achieved by the clearance slot 123. The shape of the fixed sliding rod 122 matches the shape of the fixed sliding mouth 121. The fixed structure 2 also includes a first rotating member 22 and a second rotating member 25, respectively. The movable members 23 are all rotatably connected to the fixed sliding rod 26, and the third rotating member 24 is rotatably connected between the fixed sliding rod 26 and the second rotating member 23. The fixed sliding rod 122 is rotatably connected to the sliding rod shaft 125 at one end close to the first rotating member 22. The sliding rod shaft 125 and the fixed sliding rod 26 are fixedly connected, thereby forming a linkage relationship between the three rotating members and driving the first rotating member 22, the second rotating member 23 and the third rotating member 24 to rotate through the fixed sliding rod 26, and pushing and pulling back the fixed sliding rod 122, so that the fixed sliding rod 122 can telescopically move in the fixed sliding mouth 121.
[0030] refer to Figure 3-4A scale table 3 is fixedly connected to the tooling base plate 1. The scale table 3 can adjust the rotation scale and control the telescopic distance of the fixed sliding rod 122. The fixed rotating shaft that drives the second rotating member 23 passes through the scale table 3, and a rotating handle 31 is fixedly connected at one end thereof. The movement distance of the fixed sliding rod 122 is much lower than the circumference distance of the rotating handle 31. Through the shunting of the second rotating member 23, the third rotating member 24 and the first rotating member 22, the effect of fine-tuning the position of the fixed sliding rod 122 by rotating the rotating handle 31 is achieved. By rotating the rotating handle 31, the second rotating member 23, the third rotating member 24 and the first rotating member 22 are driven A rotating member 22 rotates and drives the fixed sliding rod 122 to extend and retract. A plurality of graduated grooves 32 are arranged in an array on the scale table 3 to achieve quantitative control of the telescopic distance. A limit plate 13 is fixed on the tooling base plate 1. The limit plate 13 can form a counterposition relationship with the fixed structure 2 and abut against the surface of the muffler. The limit plate 13 is located on the side opposite to the placement slot 11 and the fixed structure 2. The inner wall of the limit plate 13 matches the outer contour of the placement slot 11. A limit guide surface 131 is provided on the top of the limit plate 13. The guide surface is convenient for placing the muffler, and the limit guide surface 131 is inclined toward the placement slot 11.
[0031] When using this mechanism, the silencer is placed on the surface of the tooling base plate 1. At this time, the side wall of the silencer will conflict with the surface of the limit plate 13, and the bottom surface of the silencer will be embedded in the placement groove body 11. The rotating handle 31 is rotated, and the rotating handle 31 will drive the first rotating member 22, the second rotating member 23 and the third rotating member 24 to rotate synchronously, and push the fixed slide bar 26 to move. The fixed slide bar 26 will push the fixed sliding rod 122 to slide toward the side wall of the silencer in the fixed sliding mouth 121. When the fixed contact plate 25 conflicts with the side wall of the silencer, stop rotating the rotating handle 31, and the side wall of the silencer will be fixed. At this time, the side wall of the silencer can be processed without shaking. When the silencer needs to be removed, the rotating handle 31 is rotated again, and the sliding contact plate will move slightly toward the side wall of the silencer and then move in the opposite direction, thereby releasing the conflict with the side wall of the silencer. The processed silencer can be taken out, the fine-tuning operation of the rotating handle 31 can be completed, and the process of fixing the silencer can be completed.
[0032] 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.
