Description

Technical Field

[0001] This utility model belongs to the technical field of automotive four-link machining, specifically relating to a four-link machining positioning device. Background Technology

[0002] The four-link rear axle is a vehicle rear axle structure system consisting of a longitudinal tie rod and three lateral links. This system achieves a balance between driving dynamics and comfort through the special stiffness design of the front lower lateral link. The independent layout of the longitudinal tie rod and the lateral links allows for the use of soft bearings to improve comfort.

[0003] When clamping and positioning automotive four-link components, a positioning device is required. However, existing positioning devices have poor clamping performance, which leads to slippage and displacement of the four-link components during clamping and positioning. This causes the machining position of the four-link components to deviate, reducing the machining accuracy of the automotive four-link components. Therefore, the development of a four-link machining positioning device has significant practical importance and market demand. Utility Model Content

[0024] Example

[0025] Reference Figure 1-4 This is an embodiment of the present utility model. This embodiment provides a four-bar processing positioning device, including a positioning component 100. The positioning component 100 includes a base box 101. Support legs 102 are fixed at the four corners of the bottom of the base box 101. A placement platform 103 is fixed on the front side of the top of the base box 101.

[0026] The inner cavity of the placement platform 103 is provided with a first clamping assembly 200 for clamping the four-bar linkage parts, and the rear side of the top of the base box 101 is provided with a second clamping assembly 300 for clamping the four-bar linkage parts.

[0027] The first clamping assembly 200 includes a sliding groove 201, which is formed on the placement table 103. A drive cylinder 202 is fixed on both the front and back sides of the inner wall of the placement table 103. A moving block 203 is fixed at the output end of the drive cylinder 202. A sliding column 204 that is slidably connected to the sliding groove 201 is fixed at the top of the moving block 203. A first clamping plate 205 is fixed at the top of the sliding column 204. By setting the first clamping assembly 200, the front and rear sides of the four-bar linkage can be clamped and positioned to prevent the four-bar linkage from sliding forward and backward, thereby improving the machining accuracy of the four-bar linkage.

[0028] Specifically, the inner side of the first clamping plate 205 is provided with a first semi-circular groove to facilitate clamping of rectangular and cylindrical four-bar parts. By setting the first semi-circular groove on the first clamping plate 205, rectangular and cylindrical four-bar parts can be clamped, improving the usage effect.

[0029] Furthermore, the second clamping assembly 300 includes a mounting base 301. The bottom of the mounting base 301 is fixedly mounted to the top of the base housing 101 by bolts. A housing 302 is fixedly mounted to the top of the mounting base 301. A drive motor 303 is fixedly mounted to the rear side of the housing 302. The output end of the drive motor 303 extends into the inner cavity of the housing 302 and is fixedly mounted with a rotating lead screw 304. Semi-circular gears 305 mesh on both sides of the rotating lead screw 304. A fixing plate 306 is fixed to the outer side of the semi-circular gears 305. The outer end of the fixing plate 306 is connected by bolts. The active rod 307 is fixedly installed, and the front end of the active rod 307 is movably connected to the connecting rod 308 via a rotating shaft. The front side of the connecting rod 308 is fixed with a second clamping plate 309, and the inner side of the connecting rod 308 is movably connected to the driven rod 310 via a rotating shaft. The rear end of the driven rod 310 is rotatably connected to the top of the housing 302 via a rotating shaft. With the setting of the second clamping assembly 300, the two sides of the four-bar linkage can be clamped and positioned to prevent the four-bar linkage from sliding left and right, thereby improving the machining accuracy of the four-bar linkage.

[0030] Preferably, a bearing seat is sleeved at the front end of the rotating screw 304, and the front side of the bearing seat is fixed to the inner wall of the housing 302. By setting the bearing seat at the front end of the rotating screw 304, the rotating screw 304 plays a stabilizing role when rotating, thereby increasing the stability of the rotating screw 304 during use.

[0031] It should be noted that rotating rods are fixed at both the top and bottom of the semi-circular gear 305, and the outer end of the rotating rod is connected to the inner wall of the housing 302 through a bearing seat. By setting the rotating rod and bearing seat on the semi-circular gear 305, the rotation of the semi-circular gear 305 can be stabilized, which increases the stability of the semi-circular gear 305 during use.

[0032] The inner side of the second clamping plate 309 is provided with a second semi-circular groove to facilitate clamping of rectangular and cylindrical four-bar parts. By setting the second semi-circular groove on the second clamping plate 309, rectangular and cylindrical four-bar parts can be clamped, improving the usage effect.

[0033] In use, the four-bar linkage is first placed on top of the placement platform 103. Then, the drive cylinder 202 is started to push the moving block 203 to move. The moving block 203 causes the sliding column 204 to slide in the inner cavity of the sliding groove 201. The moving column 204 causes the first clamping plate 205 to move to clamp and position the front and rear sides of the four-bar linkage. Then, the drive motor 303 is started to drive the rotating lead screw 304 to rotate. The rotating lead screw 304 drives the meshing semi-circular gear 305 to rotate. The semi-circular gear 305 drives the fixed plate 306 and the driving rod 307 to rotate. The rotation of the driving rod 307 drives the connecting rod 308 to rotate through the rotating shaft. The rotation of the connecting rod 308 drives the front end of the driven rod 310 to rotate in a semi-circular shape through the rotating shaft. The rear end of the driven rod 310 starts to rotate through the rotating shaft. The movement of the connecting rod 308 drives the second clamping plate 309 to move to clamp and position the two sides of the four-bar linkage, preventing the four-bar linkage from sliding and improving the machining accuracy of the four-bar linkage.

[0034] In summary, by using the first clamping assembly 200 in conjunction with the drive cylinder 202, the moving block 203, the sliding column 204, and the first clamping plate 205, the front and rear sides of the four-bar linkage can be clamped and positioned to prevent the four-bar linkage from sliding forward and backward, thus improving the machining accuracy of the four-bar linkage. By using the second clamping assembly 300 in conjunction with the drive motor 303, the rotating lead screw 304, the semi-circular gear 305, the fixed plate 306, the driving rod 307, the connecting rod 308, the second clamping plate 309, and the driven rod 310, the two sides of the four-bar linkage can be clamped and positioned to prevent the four-bar linkage from sliding left and right, thus improving the machining accuracy of the four-bar linkage.
