DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1-Figure 4 As shown, the shock absorber positioning assembly 1 includes a V-shaped seat 1-1 and a stop seat 1-2. The V-shaped seat 1-1 is used to position the outer circle of the shock absorber 3, and the stop seat 1-2 is used to position the end face of the shock absorber 3. The small piece detection assembly 2 includes a mounting plate 2-1 and an electric cylinder 2-2. The electric cylinder 2-2 is fixedly connected to the mounting plate 2-1. The front end of the electric cylinder 2-2 is connected to the pressure sensor 2-3. The front end of the pressure sensor 2-3 is connected to the detection head 2-4. The detection head 2-4 is cylindrical. One end of the shock absorber 3 can be inserted into the detection head 2-4. The end of the detection head 2-4 contacts the small piece 3-1.

[0020] A bottom plate 1-3 is provided below the V-shaped seat 1-1 and the stop seat 1-2, and a groove 1-3-1 is provided above the bottom plate 1-3. The bottom sides of the V-shaped seat 1-1 and the stop seat 1-2 are embedded in the groove 1-3-1.

[0021] Waist-shaped holes 1-4 are provided on both sides of the bottom of the V-shaped seat 1-1 and the stop seat 1-2, and a plurality of mounting holes 1-3-2 are provided in the groove 1-3-1.

[0022] A V-shaped block 1-2-1 is installed on one side of the stop seat 1-2.

[0023] The top of the mounting plate 2-1 is connected to the bracket 2-5, the bracket 2-5 is installed with a pressing cylinder 2-6, the pressing cylinder 2-6 is installed with a pressing block 2-7, and the pressing block 2-7 is used to press the shock absorber 3 during small piece detection.

[0024] The model of pressure sensor 2-3 is NS-WL5.

[0025] Two groups of shock absorber positioning components 1 are arranged in parallel, and the bottom of the mounting plate 2-1 is connected to the linear drive device.

[0026] The linear drive device includes a screw rod 2-9 and a motor 2-10. The nut of the screw rod 2-9 is connected to the sliding plate 2-8. The mounting plate 2-1 is fixedly connected to the sliding plate 2-8. The screw rod 2-9 is driven by the motor 2-10.

[0027] The linear drive device is installed on the base 2-11, and the lower sides of the sliding plate 2-8 are slidingly connected to the base 2-11 through the guide rail slider mechanism 2-12.

[0028] During use, the shock absorber positioning assembly 1 is used to position the shock absorber 3. The V-shaped seat 1-1 is used to position the outer diameter of the shock absorber 3. There can be more than one V-shaped seat 1-1. The stop seat 1-2 is used to position the end face of the shock absorber 3 and acts as a stop to prevent axial movement of the shock absorber 3 during strength testing. The shock absorber 3 can be placed on the V-shaped seat 1-1 for positioning manually or by a robot. During testing, the electric cylinder 2-2 pushes the test head 2-4 against the small piece 3-1 of the shock absorber 3. The cylindrical shape of the test head 2-4 ensures that the small piece 3-1 can contact the end face of the test head 2-4 regardless of its orientation. The applied pressure is detected by the pressure sensor 2-3. When the pressure reaches a set value, if the small piece 3-1 does not fail or fracture, the product is qualified. Alternatively, the electric cylinder 2-2 can be controlled to move a certain distance and then determine whether the pressure on the small piece 3-1 meets a set range to test the product. The specific model of the pressure sensor 2-3 can be NS-WL5, and the appropriate range can be selected according to the design requirements. During the test, the compression cylinder 2-6 can be used to drive the compression block 2-7 to press the shock absorber 3, making the test more stable.

[0029] The groove 1-3-1 on the base plate 1-3 facilitates the installation of the V-shaped seat 1-1 and the stop seat 1-2 in a straight line. The V-shaped seat 1-1 and the stop seat 1-2 can be fixedly connected to the base plate 1-3 by passing bolts through the waist-shaped hole 1-4 and the mounting hole 1-3-2. When the model needs to be changed, the V-shaped seat 1-1 and the stop seat 1-2 can be installed to the required position through the waist-shaped hole 1-4 and multiple mounting holes 1-3-2 to adapt to the rapid model change of products of different lengths. The V-shaped seat 1-1 and the stop block 1-2 can also be replaced to adapt to products of different diameters. Providing a V-shaped block 1-2-1 at one end of the stop seat 1-2 can position the outer circle of the shock absorber 3 near the end, so that only one V-shaped seat 1-1 is required to support both sides of the shock absorber 3.

[0030] To improve inspection efficiency, two sets of vibration damper positioning assemblies 1 can be installed. A motor 2-10 drives the screw 2-9 to rotate, thereby moving the sliding plate 2-8. This allows the small piece detection assembly 2 to align with the two vibration dampers 3 for inspection, allowing two products to be inspected in one loading. The two sides of the sliding plate 2-8 are slidably connected to the base 2-11 via a guide rail and slider mechanism 2-12, providing stable support and ensuring greater stability for the mounting plate 2-1 during inspection.
