[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1 - Figure 5 The device shown is a quality testing device for the front fork riser of an electric vehicle, including an operating table 1, a tensile testing component 3, and a pressure testing component 4. Control panel 1, used to support the entire device; like Figure 4As shown, the tension detection component 3 is used to perform quality inspection on the fork riser. It is equipped with a tension-compression sensor for detecting tension. The tension detection component 3 includes a base 31, which is used to connect various components. It is located on the right side of the operating platform 1. The base 31 is fixedly connected to the top of the operating platform 1. A hydraulic cylinder 32 is fixedly connected to the top of the base 31. The hydraulic cylinder 32 controls the movement of the mounting frame 33, so that the mounting frame 33 can pull the fork riser through two fixing parts 34, thereby detecting the connection stability between the riser and the fork shoulder. An output rod is provided on the left side of the hydraulic cylinder 32. The mounting frame 33 is fixedly connected to the left side of the hydraulic cylinder 32, which is used to connect various components. Fixing parts 34 are provided on both the upper and lower parts of the mounting frame 33. The two fixing parts 34 are symmetrically arranged.

[0018] The fixing component 34 includes a control rod 341, which is used to adjust the position of the clamping block 342. The control rod 341 passes through and is threadedly connected to the mounting frame 33. The lower part of the control rod 341 is rotatably connected to the clamping block 342, which is used to fix the riser. The top of the clamping block 342 is fixedly connected to two auxiliary rods 343, which are used to control the movement direction of the clamping block 342, so that the clamping block 342 can only move up and down. The two auxiliary rods 343 pass through and are slidably connected to the mounting frame 33. V-shaped grooves are opened on the side of the two clamping blocks 342 that are close to each other, so that the clamping block 342 can better fit the riser with the diameter of the body. Anti-slip pads are fixedly connected in the V-shaped grooves. The anti-slip pads can be made of rubber.

[0019] like Figure 1 - Figure 3 As shown, the pressure detection component 4 is used for pressure detection of the front fork riser. It is equipped with a pressure sensor, which can be model QTQ501. The pressure detection component 4 includes two guide rods 41. The two guide rods 41 are slidably connected to the outside of the two guide blocks 42. The top of the two guide blocks 42 is fixedly connected to the bracket 43. The guide rods 41 and guide blocks 42 are used to adjust the position of the bracket 43. The guide rods 41 and guide blocks 42 can be electrically driven. A hydraulic cylinder 44 is installed on the top of the bracket 43, which is used to drive the pressure block 45 to move. The output rod of the hydraulic cylinder 44 passes through and is movably connected to the bracket 43. The bottom of the output rod of the hydraulic cylinder 44 is fixedly connected to the pressure block 45, which is used to apply pressure to the front fork riser.

[0020] like Figure 5As shown, a fixing component 2 is provided on the top left side of the operating platform 1. It is used to fix the fork shoulder of the fork, so as to cooperate with the detection of the fork riser. The fixing component 2 includes a base 21, which is used to connect various components. A top plate 22 is provided on the upper part of the base 21. The front and rear parts of the top plate 22 are slidably connected to limit rods 24, which are used to limit the movement direction of the top plate 22, so that the top plate 22 can only move up and down. An adjusting rod 23 is rotatably connected to the left side of the base 21. The adjusting rod 23 is threadedly connected to the top plate 22 through a threaded sleeve. The threaded sleeve is fixedly connected to the top plate 22, so that when the adjusting rod 23 rotates, it can drive the top plate 22 to move up and down. Limiting blocks 25 are fixedly connected to the front and rear parts of the base 21 and the top plate 22 on the side close to each other. They are used to fix the fork shoulder. The two symmetrically arranged limiting blocks 25 are provided with V-shaped grooves on the side close to each other. Anti-slip pads, which can be made of rubber, are fixedly connected in the V-shaped grooves.

[0021] The working principle of this device is as follows: The electric vehicle front fork riser to be tested is placed on the testing device. The two sides of the fork shoulder, which is fixed to the riser, are respectively clamped into the V-shaped grooves of the two lower limiting blocks 25. Then, the adjusting rod 23 is rotated, causing it to move the top plate 22 downward through the screw sleeve. This causes the two upper limiting blocks 25 to cooperate with the lower limiting block 25, fixing the fork shoulder. Then, the output rod of the hydraulic cylinder 32 controls the movement of the mounting frame 33, which moves the two fixing parts 34 to the appropriate position. Then, the control rod 341 is rotated, causing the clamping block 342 to move towards the riser until the two clamping blocks 342 clamp the riser. Finally, the hydraulic cylinder 32 pulls the riser, thereby testing the connection quality between the riser and the fork shoulder. If a pressure test is required on the riser, follow the steps above: fix the fork shoulder with the fixing component 2, then move the bracket 43 by the guide rod 41 and guide block 42 to move the pressure block 45 to the appropriate position, then open the hydraulic cylinder 44 to drive the pressure block 45 down, so that the pressure block 45 applies pressure to the riser, thereby performing a quality test on the riser.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
