Description

Technical Field

[0001] This utility model relates to the field of clamping fixture technology, and in particular to a positioning fixture for fixing the H-arm of an automobile. Background Technology

[0002] The automotive H-arm itself has four docking arms, and the heights of the docking arms are not on the same plane. Conventional clamping fixtures use four clamping cylinders to clamp and fix the four docking arms of the product. However, this clamping method has a problem: it cannot clamp the H-arm quickly and accurately. In order to improve clamping efficiency, it is necessary to fix the positioning fixture. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a positioning fixture for fixing the H-arm of an automobile, which has the characteristics of improving the clamping efficiency of the H-arm, improving the positioning accuracy of the product, and facilitating worker operation.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A positioning clamp for fixing an H-arm of an automobile is provided, including a clamp base plate, a rear oil supply panel, and an oil reservoir; a first clamping cylinder is installed at the front left of the upper end face of the clamp base plate, a second clamping cylinder is installed at the front right of the upper end face of the clamp base plate, a third clamping cylinder is installed at the rear left of the upper end face of the clamp base plate, and a fourth clamping cylinder is installed at the rear right of the upper end face of the clamp base plate. The clamping end of the first clamping cylinder is horizontally facing right, the clamping end of the second clamping cylinder is facing right rearward, the clamping end of the third clamping cylinder is horizontally facing left, and the clamping end of the fourth clamping cylinder is horizontally facing right. A vertically upward clamping base is installed below the clamping ends of the first and second clamping cylinders. A vehicle inspection base is installed below the clamping end of the oil cylinder. The vehicle inspection base includes a vertical column, a support head, and a vehicle inspection hole. The support head is installed at the middle of the upper end of the vertical column. A vehicle inspection hole is provided at the middle of the upper surface of the support head. A grid pattern is provided on the upper surface of the support head, surrounding the vehicle inspection hole. An air passage communicating with the vehicle inspection hole is provided in the clamp base plate and the vertical column. A rear oil supply panel is installed on the rear side of the clamp base plate. The upper end of the rear oil supply panel extends forward. An oil storage tank is installed at the front of the upper end of the rear oil supply panel. Oil supply pipes communicating with the first clamping oil cylinder, the second clamping oil cylinder, the third clamping oil cylinder, and the fourth clamping oil cylinder are installed in the rear oil supply panel and the clamp base plate. Several oil circuit valves are installed side by side on the front of the upper part of the rear oil supply panel.

[0005] In this technical solution, a clamping base plate is provided to facilitate the installation of the first, second, third, and fourth clamping cylinders. The first, second, third, and fourth clamping cylinders are used to fix the four support arms of the product. A clamping base is installed to support the lower side of the product. An inspection base is installed to detect whether the product is in the correct installation position.

[0006] When testing a product using the vehicle inspection base, one end of the product needs to be placed on the support head, and the product needs to block the air inspection port. When the product is placed in place without any deviation, the product will block the air inspection port, and gas will be ejected from the air inspection port. When the gas cannot be ejected and forms a certain air pressure, it means that the product is installed correctly; otherwise, it means that the product is not installed correctly.

[0007] Meanwhile, the crisscross pattern is used to increase the friction between the product and the support head, preventing the product from shifting during clamping.

[0008] As a supplement to this technical solution, a fixed column is installed below the clamping end of the fourth clamping cylinder. The installation of the fixed column is used to improve the clamping firmness of the fourth clamping cylinder on the product.

[0009] As a supplement to this technical solution, the first clamping cylinder, the second clamping cylinder, the third clamping cylinder and the fourth clamping cylinder all adopt the same cylinder structure, including a cylinder body, a clamping rod and a buffer pad. The clamping rod is installed on the main shaft of the cylinder body, and a buffer pad corresponding to the clamping rod is installed on one side of the cylinder body. In this technical solution, the buffer pad is set to reduce the impact force when the clamping rod is running.

[0010] As a supplement to this technical solution, the clamping base includes a support column and a side baffle. The support column is vertically installed on the clamp base plate. A side baffle is installed on one side of the support column. The side baffle is L-shaped and surrounds the support column. A spherical support head is installed at the upper end of the support column.

[0011] In this technical solution, spherical support heads are installed to support both ends of the product.

[0012] As a supplement to this technical solution, a cylindrical guide post is installed on the rear side of the first clamping cylinder.

[0013] As a supplement to this technical solution, a product side baffle with its right end tilted backward is installed on the left side of the second clamping cylinder.

[0014] Beneficial effects: This utility model relates to a positioning fixture for fixing H-arms of automobiles. A fixture base plate facilitates the installation of the first, second, third, and fourth clamping cylinders. These cylinders are used to fix the four support arms of the product. A clamping base provides support to the lower side of the product. A vehicle inspection base is installed to check whether the product is properly installed. This invention improves the efficiency of H-arm clamping, enhances product positioning accuracy, and facilitates worker operation. Attached Figure Description
