Description

Technical Field

[0001] The utility model relates to the technical field of vehicle test suspensions, and particularly relates to a jig tool for a vehicle KC single-axis test girder. Background Technique

[0002] The suspension system of a golf cart is a key factor affecting its comfort and handling performance. The K&C test is an important means to evaluate the performance of a vehicle's suspension. Good suspension comfort can reduce the bumpiness during vehicle driving and improve the ride smoothness and comfort. This mainly depends on the effective absorption and filtering ability of the suspension system for road unevenness. By simulating the kinematic and compliance characteristics of the vehicle under different working conditions, the performance of the suspension system can be comprehensively understood. As one of the core components of the suspension system, the design of the jig tool for the girder is directly related to the accuracy and reliability of the test.

[0003] For example, the Chinese patent with the application number 202121903487.6 discloses a general jig tool for a commercial vehicle KC test girder, which includes a girder connection back plate, a girder fixing plate, and a jig connection tooling connected in sequence, and also includes a first screw rod passing through the girder connection back plate and the girder fixing plate. Both ends of the screw rod are threadedly connected with first nuts; a second screw rod is provided between the girder fixing plate and the jig connection tooling, and the screw rod is threadedly connected with a second nut.

[0004] However, most of the existing jig tools have a simple structure. When sliding and adjusting the clamping distance between the girder connection back plate and the girder fixing plate, it is not convenient to limit the sliding of the girder connection back plate, and it is easy to produce the phenomenon that the girder connection back plate is misaligned with the girder fixing plate, resulting in inconvenient operation of clamping the girder by connecting the girder connection back plate and the girder fixing plate later, and thus reducing the test efficiency. Therefore, in view of the above technical problems, a jig tool for a vehicle KC single-axis test girder is proposed. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the utility model proposes a jig tool for a vehicle KC single-axis test girder, which is convenient to limit the sliding of the girder back plate when adjusting the clamping distance, avoids the phenomenon that the girder back plate is misaligned with the girder fixing plate, is convenient for clamping the test girder, and improves the test efficiency.

[0006] A jig tool for a vehicle KC single-axis test girder includes:

[0007] A jig assembly, including a girder fixing plate, a girder back plate, and a connecting member. The girder fixing plate and the girder back plate are arranged oppositely. The girder back plate slides closer to or farther away from the girder fixing plate to adjust the clamping distance, and the connecting member is used to connect the girder fixing plate and the girder back plate;

[0008] The positioning component includes a positioning member, which is arranged on one side of the girder fixing plate and is slidably connected to the girder back plate; and

[0009] The fixture connecting tooling can be fixed on the ground and is connected to the girder fixing plate.

[0010] The beneficial effects of the above-mentioned vehicle KC single-axis test girder fixture tooling are as follows:

[0011] The girder fixing plate is closely attached to the inner side of the test girder through the moving device, and then the girder back plate is slid along the positioning member to make the girder back plate closely attached to the outer side of the test girder. Then, the girder fixing plate and the girder back plate are connected through the connecting member to complete the clamping of the test girder. Finally, the fixture connecting tooling is fixed on the ground to conduct the test. By setting the positioning member to slidably cooperate with the girder back plate to limit the girder back plate, the phenomenon that the girder back plate is misaligned with the girder fixing plate when the clamping distance is adjusted by sliding is avoided. The operation of clamping the test girder is convenient, and the test efficiency is improved.

[0012] In one embodiment, the connecting member includes a first bolt; one end of the first bolt can penetrate through the girder back plate and is threadedly connected to the girder fixing plate. When the girder fixing plate and the girder back plate are respectively closely attached to the inner side and the outer side of the test girder, by penetrating one end of the first bolt through the girder back plate and then rotating the first bolt to be in threaded cooperation with the girder fixing plate, the girder fixing plate and the girder back plate can be connected and the test girder can be clamped, which is convenient for clamping the test girder.

[0013] In one embodiment, multiple groups of the connecting members are arranged at intervals along the length direction of the girder back plate. By setting multiple groups of connecting members, the connection stability between the girder back plate and the girder fixing plate can be improved, thereby improving the clamping stability of the test girder.

[0014] In one embodiment, the positioning member includes a rectangular block; a rectangular groove adapted to the rectangular block is opened at the bottom end of the girder back plate, and the rectangular groove is slidably sleeved on the rectangular block. Through the cooperation of the rectangular block and the rectangular groove, the sliding of the girder back plate can be guided, thereby avoiding the phenomenon that the girder back plate is misaligned with the girder fixing plate when sliding. The operation of clamping the test girder is convenient, and the test efficiency is improved.

[0015] In one embodiment, the fixture connecting tooling includes a bottom plate and a top plate; the bottom plate can be fixed on the ground, the top plate is connected above the bottom plate, the bottom end of the girder fixing plate is fixedly arranged on the top plate, the positioning member is detachably arranged on the top end of the top plate, and the bottom end of the girder back plate is attached to the top end of the top plate. The positioning member is detachably arranged, which is convenient for replacing the positioning member alone after it is damaged, reducing the use cost of the device. The bottom end of the girder back plate being attached to the top end of the top plate can further improve the stability of the girder back plate when sliding.

[0016] In one embodiment, a plurality of groups of first strip-shaped holes are spaced apart on the bottom plate, and one end of an external bolt can penetrate through the first strip-shaped holes and be threadedly connected to the ground. By threading the external bolt through the first strip-shaped holes and threadedly connecting it to the ground, the bottom plate can be fixed to the ground, and the external bolt can move along the length direction of the first strip-shaped holes, facilitating the adjustment of the screwing position of the bottom plate relative to the ground and improving the adaptability of the connection between the bottom plate and the ground.

The limit block facilitates the vertical parallel clamping of the test girder by the girder fixing plate and the girder back plate, improves the stability of clamping the test girder, and at the same time can prevent over-clamping of the test girder and avoid clamping damage to the test girder.

[0018] In one embodiment, the fixture connection tooling further includes a lifting assembly, and the top plate is connected to the bottom plate through the lifting assembly.

[0046] Then, place the limit block 303 on the top surface of the top plate 301 and between the girder fixing plate 10 and the girder back plate 101. Use the moving device to make the girder fixing plate 10 closely adhere to the inner side of the test girder. Then, slide the girder back plate 101 along the rectangular block to make the girder back plate 101 closely adhere to the outer side of the test girder. Then, pass one end of the first bolt through the girder back plate 101 and rotate the first bolt to be in threaded cooperation with the girder fixing plate 10 to connect the girder fixing plate 10 and the girder back plate 101 and clamp the test girder. It is convenient to clamp the test girder, and the sliding of the girder back plate 101 can be guided by the cooperation of the rectangular block and the rectangular groove, thus avoiding the phenomenon of dislocation between the girder back plate 101 and the girder fixing plate 10 when the girder back plate 101 slides.
