Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorbers, specifically to a machining and positioning fixture for an automotive shock absorber reservoir. Background Technology

[0002] In the production of automotive shock absorber reservoir assemblies, a type of V-block is frequently used. It is widely used in tooling and fixtures to fix and position the reservoir for processes such as welding, laser cutting, and alignment inspection. During processing, there is a requirement to fix the center height of the reservoir. Since the diameter of the reservoir often varies, conventional one-piece V-blocks cannot achieve a uniform center height and cannot be adjusted. Different models of V-blocks are required for reservoirs of different diameters, which greatly increases the changeover time and tooling and fixture costs.

[0003] Therefore, a positioning fixture that can meet the positioning requirements of different types of liquid storage cylinders is needed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a positioning fixture for machining automotive shock absorber reservoirs. This positioning fixture can meet the machining and positioning requirements of reservoirs of different models.

[0005] The purpose of this utility model is achieved by the following solution: a positioning fixture for processing automotive shock absorber reservoirs, including a mounting base, which is a U-shaped base. A linear slide rail is provided on the upper surface of the middle section of the mounting base. Two sliding blocks are arranged opposite each other on the left and right sides of the upper surface of the linear slide rail. The sliding blocks slide with the linear slide rail. A positive and negative lead screw is provided at the upper end of the mounting base. The two ends of the positive and negative lead screw are connected and fixed to the two sides of the mounting base. Sloping blocks are respectively provided at the left and right ends of the positive and negative lead screw. The inclined surfaces of the two sloping blocks are arranged oppositely to form a V-shaped positioning block. The lower end of the sloping block is connected and fixed to the sliding block. Sliding nuts are respectively provided between the two sloping blocks and the positive and negative lead screw. The threads of the two sliding nuts are turned in opposite directions. By rotating the positive and negative lead screw, the V-shaped positioning block is controlled to position shock absorber reservoirs of different specifications.

[0006] One end of the positive and negative lead screws is fixedly connected to the adjusting wheel.

[0007] A scale is provided on the front end face of the mounting base, and graduation lines are provided on the front end face of the scale. A height indicator is provided on the front end face of the slope block, and the lower end of the height indicator is in contact with the upper end face of the scale.

[0008] Locking bolts are installed on the slope block.

[0009] The two ends of the positive and negative lead screws are supported by bearings.

[0010] The advantages of this invention are that this positioning fixture has high versatility, can meet the positioning needs during the processing of shock absorber reservoirs of different specifications, improves the line change efficiency and processing efficiency during the processing of shock absorber reservoirs, and reduces production costs. Furthermore, this positioning fixture can also be applied to the fixing and positioning of other components. Attached Figure Description

[0014] like Figures 1 to 3 As shown, a positioning fixture for machining automotive shock absorber reservoirs includes a mounting base 1, which is a U-shaped base. A linear slide rail is provided on the upper surface of the middle section of the mounting base 1. Two sliding blocks 10 are arranged opposite each other on the left and right sides of the upper surface of the linear slide rail 6, and the sliding blocks 10 slide in contact with the linear slide rail 6. A positive and negative lead screw 8 is provided at the upper end of the mounting base 1. The two ends of the positive and negative lead screw 8 are connected and fixed to the two sides of the mounting base 1. Sloping blocks 5 are respectively provided at the left and right ends of the positive and negative lead screw 8. The inclined surfaces of the two sloping blocks 5 are arranged oppositely to form a V-shaped positioning block. The lower end of the sloping block 5 is connected and fixed to the sliding block 10. Sliding nuts 9 are respectively provided between the two sloping blocks 5 and the positive and negative lead screw 8. The threads of the two sliding nuts 9 are turned in opposite directions. The V-shaped positioning block is controlled by rotating the positive and negative lead screw 8 to position shock absorber reservoirs of different specifications. One end of the positive and negative lead screw 8 is connected and fixed to an adjusting wheel 7. The two ends of the positive and negative lead screw 8 are supported by bearings 11. A scale 2 is provided on the front end face of the mounting base 1, and scale lines are provided on the front end face of the scale 2. A height indicator 3 is provided on the front end face of the slope block 5, and the lower end of the height indicator 3 is in contact with the upper end face of the scale 2. A locking bolt 4 is provided on the slope block 5, and the position of the slope block 5 is locked by the locking bolt 4 after the slope block 5 reaches the designated position.

[0015] This positioning fixture is based on the principle that a lead screw can convert rotary motion into linear motion. It uses positive and negative lead screws to rotate the adjustment wheel to drive the slope block to move relative to each other, so that the V-block is adjustable and the center height of the liquid storage cylinder is consistent. After adjustment, the V-block can be fixed with locking bolts to ensure machining accuracy. Repeated adjustments can also be made by using a ruler and pointer to quickly determine various heights.
