Description

Technical Field

[0001] The utility model relates to the technical field of automotive suspension accessory tests, and particularly relates to a test device for automotive suspension springs. Background Art

[0002] An automotive suspension refers to a connection structure system between the vehicle body, the frame and the wheels, which includes components such as shock absorbers, springs, anti-roll bars, suspension sub-beams, lower control arms, longitudinal rods, steering knuckle arms, rubber bushings and connecting rods. Among them, after the automotive suspension spring is processed, it usually needs to be tested to ensure the quality performance of the automotive suspension spring. In the process of using the existing automotive suspension spring test equipment, since it can only be used to test automotive suspension springs of a single diameter specification and cannot meet the test requirements of automotive suspension springs of different diameter specifications, the test application range is limited, affecting the applicability when testing automotive suspension springs. Therefore, we propose a test device for automotive suspension springs to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide a test device for automotive suspension springs to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A test device for automotive suspension springs includes a test bench. A carrier seat is fixedly installed on the surface of the test bench. Two sliders are symmetrically and slidably connected to the carrier seat. A positioning stop block is fixedly installed at the top of one end of each slider, and a transmission sleeve is fixedly installed at the other end of each slider. A bidirectional screw rod is rotatably connected to the test bench through a bearing seat. The two transmission sleeves are respectively threadedly sleeved on the front and rear sections of the bidirectional screw rod. A telescopic cylinder is fixedly installed on the upper end of the test bench through a vertical frame. The telescopic end of the telescopic cylinder is fixedly connected to a test pressure column. A guiding column is opened on the bottom surface of the test pressure column. A guiding slot is fixedly connected to the middle of the surface of the carrier seat. The guiding slot is adapted to the guiding column.

[0006] Preferably, a support seat is fixedly installed on one side of the test bench, and one end of the bidirectional screw rod movably penetrates through the support seat and extends to the outside.

[0007] Preferably, a screwing block is fixedly connected to the end of the bidirectional screw rod, and the cross-sectional shape of the screwing block is a regular hexagon.

[0008] Preferably, the cross-sectional shape of the carrier seat is circular, and the top surface of the carrier seat is flush with the top surface of the slider.

[0009] Preferably, a guiding seat is fixedly sleeved outside the test pressure column, and the guiding seat is slidably sleeved outside the vertical frame.

[0010] Preferably, a reinforcing seat is fixedly connected between the test bench and the vertical frame, and the cross-sectional shape of the reinforcing seat is triangular.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, according to the diameter specification of the automotive suspension spring to be tested, when it is necessary to adjust the relative distance between the two positioning blocks, the bidirectional screw is rotated by using the screwing block, which can drive the two sliders to slide closer to or away from each other along the carrier until the two positioning blocks are adjusted to the required relative distance, so that the end edges of the two positioning blocks are in contact with the inner circumferential surface of the automotive suspension spring. The telescopic cylinder is used to drive the test pressure column to slowly press down, and the automotive suspension spring contracts due to the pressure applied by the test pressure column. When the test pressure column descends to the required position, the telescopic cylinder is used to drive the test pressure column to slowly rise and reset, and then the recovery condition of the automotive suspension spring is checked to judge the test result. It can adaptively position and place the automotive suspension spring, which is convenient to meet the test requirements of automotive suspension springs with different diameter specifications, is beneficial to increasing the test use range, and improves the applicability when testing and processing automotive suspension springs.

Detailed Embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-4 as shown in the figure, a technical solution provided by the present invention:

[0020] An automotive suspension spring test device includes a test bench 1. A carrier 2 is fixedly installed on the surface of the test bench 1. Two sliders 3 are symmetrically and slidably connected to the carrier 2. A positioning block 301 is fixedly installed at the top of one end of the slider 3, and a transmission sleeve 302 is fixedly installed at the other end of the slider 3. A bidirectional screw 4 is rotatably connected to the test bench 1 through a bearing block 101. The two transmission sleeves 302 are respectively threadedly sleeved on the front and rear sections of the bidirectional screw 4. A telescopic cylinder 6 is fixedly installed at the upper end of the test bench 1 through a vertical frame 5. The telescopic end of the telescopic cylinder 6 is fixedly connected to a test pressure column 7. A guide post 701 is opened on the bottom surface of the test pressure column 7. A guide slot 201 is fixedly connected to the middle of the surface of the carrier 2. The guide slot 201 is adapted to the guide post 701. The guide slot 201 on the bottom surface of the test pressure column 7 is slidably inserted into the guide post 701 to guide the test pressure column 7.

[0021] As a preferred implementation manner in this embodiment, as Figure 3 shown, a support seat 102 is fixedly installed on one side of the test bench 1. One end of the bidirectional screw 4 movably penetrates through the support seat 102 and extends to the outside. The support seat 102 can effectively support the bidirectional screw 4.

[0022] As a preferred implementation manner in this embodiment, as Figure 3 shown, a screwing block 401 is fixedly connected to the end of the bidirectional screw 4. The cross-sectional shape of the screwing block 401 is a regular hexagon, achieving the purpose of facilitating the screwing and rotation of the bidirectional screw 4.

[0023] As a preferred implementation manner in this embodiment, as Figure 2 shown, the cross-sectional shape of the carrier 2 is circular, and the top surface of the carrier 2 is flush with the top surface of the slider 3, ensuring the flatness of the top surface of the overall appearance formed by the carrier 2 and the slider 3.

[0024] As a preferred implementation manner in this embodiment, as Figure 2 shown, a guide seat 8 is fixedly sleeved outside the test pressure column 7. The guide seat 8 is slidably sleeved outside the vertical frame 5, which is beneficial to ensuring the stability of the test pressure column 7 during the lifting movement.

[0025] As a preferred implementation mode in this embodiment, as Figure 4 shown, a reinforcing seat 103 is fixedly connected between the test bench 1 and the vertical frame 5. The cross-sectional shape of the reinforcing seat 103 is triangular, achieving the purpose of improving the connection structural strength between the test bench 1 and the vertical frame 5.

[0026] Working principle:

[0027] During use, place the automotive suspension spring 9 to be tested on the carrier seat 2. According to the diameter specification of the automotive suspension spring 9 to be tested, if it is necessary to adjust the relative distance between the two positioning blocks 301, use the screwing block 401 to screw and rotate the bidirectional screw rod 4, which can drive the two sliders 3 to slide closer to or away from each other along the carrier seat 2 until the two positioning blocks 301 are adjusted to the required relative distance, so that the end edges of the two positioning blocks 301 are in contact with the inner circumferential surface of the automotive suspension spring 9, thereby enabling the adaptive positioning and placement of the automotive suspension spring 9. Use the telescopic cylinder 6 to drive the test pressure column 7 to slowly press down. The guiding slot 201 on the bottom surface of the test pressure column 7 is slidably inserted into the guiding column 701, thereby guiding the test pressure column 7. The automotive suspension spring 9 undergoes a certain contraction under the pressure applied by the test pressure column 7. When the test pressure column 7 drops to the required position, use the telescopic cylinder 6 to drive the test pressure column 7 to slowly rise and reset, and then check the recovery condition of the automotive suspension spring 9 to judge the test result.
