Abstract
Description
Technical Field
[0001] The utility model relates to the field of bushing testing, and specifically relates to an automobile bushing testing tooling. Background Technique
[0002] An automobile bushing is an important component in an automobile suspension system, and it is usually made of materials such as rubber, plastic or metal. The main function of the bushing is to buffer, shock-absorb and absorb noise during vehicle driving. When an automobile is driving on the road, the road surface will continuously transmit various vibrations and noises to the vehicle body. Without the bushing, these vibrations and noises will be directly transmitted into the vehicle, making passengers feel uncomfortable and affecting the durability of the automobile. The bushing can effectively absorb and disperse these vibrations and noises, protecting the comfort of passengers in the vehicle and other components of the automobile from damage.
[0003] After retrieval, a Chinese utility model patent CN210347111U, an automobile bushing testing tooling, includes a base and a bottom plate arranged on the base. On both sides of the upper end of the bottom plate, columns are symmetrically arranged. The columns are inverted T-shaped, and their bottoms extend outwards and inwards respectively on both sides. Horizontal through grooves are opened along the length direction on both sides of the bottom plate. A first fixing bolt penetrates through the outer side edge, and the first fixing bolt is inserted into the corresponding horizontal through groove to fix the column on the bottom plate. A bushing to be tested is arranged between the two columns, and the bottom of the bushing to be tested is erected on the two inner side edges. An arc-shaped fastener is connected to the side of the column close to the bushing to be tested.
[0004] The following problems will occur when the existing device is in use: When performing a stiffness test on an automobile bushing, the automobile bushing is placed on the tooling, and then the limit component is manually adjusted. However, when manually adjusting the limit component, the automobile bushing needs to be manually held and fixed on the tooling, which is rather inconvenient to operate and reduces the test efficiency. Content of the Utility Model
[0005] The purpose of the utility model is to provide an automobile bushing testing tooling to solve the problems raised in the above background technique.
[0006] To achieve the above object, the utility model provides the following technical solution: An automobile bushing testing tooling, including a bottom plate, a control chamber, and an adjustment chamber. A control chamber is arranged inside the bottom plate. An electric push rod is installed in the control chamber. The output end of the electric push rod is tightly connected with a hinge block B. A connecting rod is hinged inside the hinge block B. The top end of the connecting rod is hinged with a hinge block A. A inner clamping block is fixedly connected to the top of the hinge block A. Starting the electric push rod drives the hinge block B to descend. The hinge block B drives the two connecting rods to move. Thus, the connecting rods cooperate with the hinge block A to drive the inner clamping block to move towards the inner wall of the bushing. The two inner clamping blocks are in an inverted V shape. The use of the teeth increases the contact area with the inner wall of the bushing, thereby limiting and fixing the bushing, reducing the operation time increased by manual holding. Adjustment chambers are arranged on both sides of the control chamber. A rotating motor is installed in the adjustment chamber. The output end of the rotating motor is tightly connected with a lead screw. A sliding seat is threadedly connected to the upper surface of the lead screw. A connecting block is fixedly connected to the top of the sliding seat. Starting the rotating motor in the adjustment chamber drives the lead screw to rotate. The lead screw cooperates with the sliding seat to drive the limiting clamping block at the top to move, thereby clamping and fixing the bushing. An electric telescopic rod is installed inside the connecting block. The output end of the electric telescopic rod is fixedly connected with a limiting clamping block. Starting the electric telescopic rod drives the limiting clamping block to rise, so that it can be adjusted according to the height of the bushing. A base is arranged at the bottom of the bottom plate.
[0007] In a further embodiment, a tooth is arranged on one side of the inner clamping block. The material of the tooth is set as rubber, increasing the anti-slip effect and improving the fixing strength.
[0008] In a further embodiment, a guide rod is arranged inside the adjustment chamber. The sliding seat is slidably connected to the guide rod, so that the sliding seat maintains a linear motion when moving.
[0009] In a further embodiment, a slider is arranged inside the limiting clamping block. The slider is slidably connected to a sliding rod. The sliding rod is located between the connecting block and the limiting clamping block, increasing the smoothness when the limiting clamping block moves.
[0010] In a further embodiment, a limiting top plate is arranged on one side of the limiting clamping block. The limiting top plate fixes one end of the bushing, improving the stability. An anti-slip pad is arranged on one side of the limiting clamping block, improving the anti-slip effect.
[0011] In a further embodiment, a notch is opened at the top of the bottom plate. A sliding seat is arranged inside the notch. The sliding seat moves inside the notch.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The connecting rod cooperates with the hinge block A to drive the inner clamping block to move towards the inner wall of the bushing. The two groups of inner clamping blocks are in an inverted V shape, and the clamping teeth are used to increase the contact area with the inner wall of the bushing, thereby limiting and fixing the bushing. Thus, the inner clamping block pre-fixes the bushing, avoiding manual holding during fixation and increasing the convenience of use.
[0014] Start the electric telescopic rod to drive the limit clamping block to rise. The limit block cooperates with the limit top plate to limit and fix the bushing, so that it can be adjusted according to the height of the bushing to meet the needs of different bushing tests and improve the practicability.

An electric telescopic rod 19 is installed in the connecting block 6. The output end of the electric telescopic rod 19 is fixedly connected with the limiting clamping block 3. A guide rod 10 is provided inside the adjustment chamber 20. The guide rod 10 is slidably connected with the sliding seat 9. Start the electric telescopic rod 19 to drive the limiting clamping block 3 to rise, so that it can be adjusted according to the height of the bushing to meet different bushing testing requirements. A notch is provided at the top of the bottom plate 1. The sliding seat 9 is arranged in the notch and moves in the notch. A limiting top plate 4 is provided on one side of the limiting clamping block 3. The limiting top plate 4 fixes one end of the bushing to improve stability. A slider 5 is provided inside the limiting clamping block 3. The slider 5 is slidably connected with a sliding rod 13.

[0023] Working principle: Connect the base 2 with the test equipment. Insert the bushing outside the inner clamping block 11. Start the electric push rod 17 to drive the articulated block B16 to descend. The articulated block B16 drives the two groups of connecting rods 15 to move. Thus, the connecting rods 15 cooperate with the articulated block A14 to drive the inner clamping block 11 to move towards the inner wall direction of the bushing. The two inner clamping blocks 11 are in an inverted V shape, and the clamping teeth 12 are used to increase the contact area with the inner wall of the bushing, thereby limiting and fixing the bushing. Start the rotating motor 7 in the adjustment chamber 20 to drive the lead screw 8 to rotate. The lead screw 8 cooperates with the sliding seat 9 to drive the top limiting clamping block 3 to move, thereby clamping and fixing the bushing. Start the electric telescopic rod 19 to drive the limiting clamping block 3 to rise, so that it can be adjusted according to the height of the bushing. The limiting top plate 4 fixes one end of the bushing to improve stability.
