The top of the chassis is equipped with the positioning component, two slide rails, and a reference insertion block. One end of each slide rail is located at the edge of the chassis, and the other end extends towards the positioning component. The reference insertion block is located at the other end of the slide rail. Each slide rail has a slidable shape-changing block mounted on it. The V-shaped support component is vertically fixed to the top of the shape-changing block. Both ends of the movable insertion block are inserted into grooves on the top of the shape-changing block. One end of the shape-changing limit block passes through a through hole in the reference insertion block. The shape-changing limit block and the reference insertion block are connected by a shape-changing positioning pin. The other end of the shape-changing limit block is fixed to a groove at the bottom of the movable insertion block.

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] See Figure 1 , Figure 4This utility model is an assembly tray for a parallel-axis electronic power steering system, including a chassis, a positioning component, a V-shaped support component, slide rails, a changing block, a movable insertion block, a reference insertion block, a changing limit block, and a changing positioning pin. The top of the chassis 3 is equipped with a positioning component, two slide rails 8, and a reference insertion block 10. One end of the slide rail 8 is located at the edge of the chassis 3, and the other end of the slide rail 8 extends towards the positioning component. The reference insertion block 10 is located at the other end of the slide rail 8. Each slide rail 8 is equipped with a slidable changing block 6. The V-shaped support component is vertically fixed to the top of the changing block 6. The two ends of the movable insertion block 9 are respectively inserted into the grooves on the top of the changing block 6. One end of the changing limit block 11 passes through the through hole of the reference insertion block 10. The changing limit block 11 and the reference insertion block 10 are connected by a changing positioning pin 12. After the changing positioning pin 12 is vertically inserted into the round hole on the top of the reference insertion block 10, it is connected to the positioning round hole at one end of the changing limit block 11. The other end of the change-limiting block 11 is fixed to the groove at the bottom of the movable insertion block 9.

[0023] The chassis 3 has positioning holes 31 at its four corners. Each positioning hole 31 is an embedded pin sleeve structure, which is secured to the chassis 3 with a nut. The positioning holes 31 are used for positioning the chassis 3.

[0024] The positioning assembly includes a support block 5 and a positioning pin assembly 4. The support block 5 is fixed to the top of the chassis 3, and the positioning pin assembly 4 is inserted into the mounting hole on the top of the support block 5.

[0025] See Figure 2 The positioning pin assembly 4 includes a product positioning pin 41, a pull pin 42, and a connecting block 43. The product positioning pin 41 is fixed to the top of one end of the connecting block 43. The upper end of the pull pin 42 is embedded in a groove at the bottom of the other end of the connecting block 43. The pull pin 42 is fixed to the side of the connecting block 43 with a countersunk bolt. The lower end of the pull pin 42 is inserted into the mounting hole at the top of the support block 5. A suitable positioning pin assembly 4 can be replaced according to different steering gear products. When replacing, simply pull the pull pin 42 to disconnect the support block 5 from the positioning pin assembly 4, and then reinstall the suitable positioning pin assembly 4.

[0026] See Figure 3 The V-shaped support assembly includes a V-shaped support frame 1 and a base 2. The V-shaped support frame 1 is fixed to the top center of the base 2. Base 2 has base positioning pins 21 on both sides of its bottom, which are inserted into the positioning pin holes of the changing block 6. The V-shaped support assembly is used to support the housing of the steering gear product and can slide with the changing block 6 to adjust the distance between the V-shaped support assembly and the positioning assembly, adapting to the length of different steering gear products.

[0027] For ease of installation, the shape-changing block 6 is fixed to the top of the slider 7, and the slider 7 is slidably connected to the slide rail 8.

[0028] For ease of connection, fasteners are used to fix the shape-changing block 6 and the movable socket block 9, the shape-changing limit block 11 and the movable socket block 9, and the shape-changing block 6 and the slider 7.

[0029] To avoid interference, the change-fit limit block 11 and the reference socket block 10, and the change-fit positioning pin 12 and the reference socket block 10 are fitted with clearance.

[0030] Different changeover limit blocks 11 correspond to different steering gear product lengths. This invention allows for direct adjustment of the sliding block 45 based on the different lengths of the changeover limit blocks 11, ensuring efficiency and accuracy in changeover. After the sliding block 45 is adjusted to the correct position, it is fixed by connecting and securing the reference insertion block 10, changeover limit blocks 11, moving insertion block 9, changeover block 9, and V-shaped support assembly to prevent wobbling. After adjustment, the steering gear product is positioned using the product positioning pin 41, and the V-shaped support frame 1 provides support, ensuring stability and accuracy during assembly.

[0031] This invention, through its connection structure of a reference insertion block, a shape-changing limiting block, a movable insertion block, a shape-changing block, and a V-shaped support assembly, ensures the stability and accuracy of the assembly process.
