Description

Technical Field

[0001] The utility model belongs to the technical field of automobile installation, in particular to a positioning fixture for automobile parts. Background Art

[0002] A fixture is a device used to fix the workpiece in the mechanical manufacturing process so that it occupies the correct position for construction or testing. It is also called a clamp. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process can be called a fixture. Fixtures are widely used in various fields.

[0003] When maintenance personnel are installing and repairing tires, the car is supported in the air and usually needs to be manually carried to the designated location. Multiple people need to cooperate in the installation. This not only puts too much physical strain on the human body, but also easily causes shaking during the manual support process, resulting in deviation when docking with the car body, greatly reducing the installation efficiency. Therefore, we proposed an automobile component positioning fixture. Utility Model Content

[0004] The purpose of the utility model is to provide a positioning fixture for automobile parts. By setting a clamping component, the inner wall of the tire is fixed. The use of a clamping tool can reduce errors caused by human factors, such as deviation or shaking during manual alignment. This high-precision installation method helps to ensure a close fit between the tire and the wheel hub, ensures the quality of automobile parts installation, and improves the efficiency of installation. It solves the problem that the existing manual transportation of tires to a designated position and the coordinated installation of multiple personnel not only puts too much physical effort on the human body, but also easily causes shaking during the manual support process, thereby causing deviations when docking with the car body, greatly reducing the work efficiency of installation.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a positioning fixture for automobile parts, comprising a support, a square groove is provided inside the support, a motor is fixedly connected to the top of the support, a roller is rotatably connected to the bottom of the support, a support block is provided on the front of the support, and the roller facilitates the operator to adjust the position of the automobile parts during operation;

[0007] The surface of the support block is provided with a clamping assembly, and the clamping assembly includes a frame fixedly connected to the front of the support block, the inner wall of the frame is slidably connected to two arc rods, the interior of the two arc rods are provided with arc grooves, the inner walls of the two arc grooves are slidably connected to sliding rods, the outer surfaces of the two sliding rods are fixedly connected to support rods, and the sides of the two support rods close to each other are fixedly connected to a fixed block, and the side of the fixed block close to the support block is fixedly connected to a screw rod, the screw rod slides through the side wall of the support block and extends to the inside, and the extended end of the screw rod is fixedly connected to a limiting block. When the sliding rod is pulled, the arc rods on both sides expand outward away from the side of the fixed block to fix the inner wall of the tire. The use of clamping tools can reduce errors caused by human factors.

[0008] Furthermore, a lifting assembly is provided inside the square groove, and the lifting assembly includes a threaded rod fixedly connected to an output end of a motor, the top and bottom of the threaded rod are rotatably connected to the inner wall of the support, the outer surface of the threaded rod is threadedly connected to a moving block, the front of the moving block is fixedly connected to the back of the support block, and the support block can be effectively and smoothly driven to move upward through the rotation of the threaded rod.

[0009] Furthermore, the side of the moving block away from the supporting block is fixedly connected to a support plate, the top of the support plate is fixedly connected to a round rod, and the outer surface of the round rod is slidably connected to several counterweight blocks. The main function of the counterweight blocks is to balance the weight distribution, which can reduce the shaking or tilting caused by uneven weight distribution, thereby improving the stability of lifting.

[0010] Furthermore, the top of the support block is fixedly connected to motor 2, the output end of motor 2 is fixedly connected to a transmission shaft, the end of the transmission shaft away from motor 2 is fixedly connected to a main gear, the bottom of the main gear is meshed with a sub-gear, the inner wall of the sub-gear is threadedly connected to the outer surface of the screw rod, and the purpose of synchronous movement can be achieved by utilizing the mutual meshing transmission of the two gears.

The limiting ring provides support for the rotating secondary gear, so that the secondary gear can maintain an engagement state with the main gear, thereby enabling it to rotate stably.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model provides a clamping assembly. Specifically, the fixed block drives the support rods on both sides to pull the sliding rod to move during the movement toward the supporting block. The sliding rod slides on the inner wall of the arc groove opened inside the arc rod. When the sliding rod is pulled, the arc rods on both sides expand outward away from the side of the fixed block to fix the inner wall of the tire. The use of clamping tools can reduce errors caused by human factors, such as deviation or shaking during manual alignment. This high-precision installation method helps to ensure a close fit between the tire and the wheel hub, ensures the quality of automobile accessories installation, and improves installation efficiency.

[0014] 2. The utility model sets a lifting assembly, specifically, a starting motor drives the threaded rod to rotate clockwise. As the threaded rod rotates, the moving block is driven to move upward, and the moving block drives the support block to move upward, thereby driving the tire to move toward the installation position of the car. The moving block principle: A detachable counterweight block is set on one side of the support block. The number of counterweight blocks can be configured according to the weight of the car parts to be lifted. The main function of the counterweight block is to balance the weight distribution, which can reduce the shaking or tilting caused by uneven weight distribution, thereby improving the lifting stability. The support block steadily lifts the tire to an appropriate height, so that maintenance personnel can easily access the tire installation position, ensure the accuracy of the tire during installation, and avoid installation problems caused by inaccurate alignment.

The moving block 302 is provided with a detachable counterweight block 305 on one side of the support block 104. The number of counterweight blocks 305 can be configured according to the weight of the car parts to be lifted. The main function of the counterweight block 305 is to balance the weight distribution, especially in the process of lifting the tire, it can reduce the shaking or tilting caused by uneven weight distribution, thereby improving the lifting stability. The support block 104 steadily lifts the tire to an appropriate height, so that maintenance personnel can easily access the tire installation position, ensure the accuracy of the tire during installation, avoid installation problems caused by inaccurate alignment, and do not need to manually move the tire or use other tools for assistance, thereby greatly improving the efficiency of tire installation.
