Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a shock absorber expansion and contraction life detection device. Background Art

[0002] Shock absorbers are widely used parts in automobiles. Their main function is to absorb impact force. For example, when closing a door, the shock absorber contracts to absorb the impact force of the door on the frame, thus preventing damage caused by the collision between the door and the frame. As a retractable part, the shock absorber has a certain service life. When the factory produces shock absorbers, it is necessary to test the life of the shock absorbers. After repeatedly retracting and retracting the shock absorbers a certain number of times, it is necessary to test whether the retracted shock absorbers can be completely reset to determine whether the service life meets the standard. Different shock absorbers have different retraction distances. The existing shock absorber retraction life detection equipment is for a single model of shock absorbers and cannot detect multiple models of shock absorbers. Therefore, a retraction life detection equipment that can adapt to different models of shock absorbers is needed. Utility Model Content

[0003] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0004] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a shock absorber expansion and contraction life detection device, including a base, a baffle fixed on the base, a driving mechanism fixed on the base, an electric control mechanism fixed on the base, and a detection mechanism fixed on the base; the driving mechanism includes a motor fixed on the base, a fixing component fixed on the base, an adjustment component fixed on the motor, and a pushing component fixed on the adjustment component. The base is placed on the ground; the driving mechanism is used to drive the adjustment component and the pushing component to perform a life test on the shock absorber; the electric control mechanism is used to control the operation of the motor and count the number of times the shock absorber is compressed; the motor speed is adjustable; the fixing component is used to fix the shock absorber; the adjustment component is used to adjust the movement stroke of the pushing component. Since the shock absorption stroke of different models of shock absorbers is different, the movement stroke of the pushing component needs to be adjusted to adapt to different models of shock absorbers; the pushing component is driven by the motor to repeatedly push the shock absorber to expand and contract for life testing.

[0005] Specifically, the electric control mechanism includes a first controller fixed on the base, a first display screen fixed on the first controller, a plurality of first buttons fixed on the first controller, a second controller fixed on the base, a second display screen fixed on the second controller, and a plurality of second buttons fixed on the second controller. The first controller is used to control the motor speed; the first display screen displays the current motor speed; the first button is used to adjust the motor speed. Different models of shock absorbers have different rebound speeds, so the motor speed needs to be adjusted to avoid the shock absorber being compressed again before it rebounds completely; the second controller is used to control the sensor; the second display screen is used to display the current number of shock absorber tests; the second button is used to set the number of tests.

[0006] Specifically, the fixing assembly includes a fixing seat fixed on the base, a fixing plate arranged on the fixing seat, and a shock absorber fixed on the fixing plate. The fixing seat is fixed on the base; the fixing plate is fixed on the fixing seat by screws; and the shock absorber to be tested is fixed on the fixing plate.

[0007] Specifically, the adjustment component includes a rotating rod fixed on the motor, a first sliding groove fixed on the rotating rod, an adjustment seat slidably arranged on the sliding groove, a threaded rod fixed on the adjustment seat, a nut rotatably arranged on the threaded rod, and a clearance groove fixed on the base. The rotating rod is fixedly connected to the motor shaft; the adjustment seat and the threaded rod can slide on the first sliding groove; the nut is used to fix the threaded rod and the adjustment seat; the clearance groove makes way for the rotating rod; loosen the nut, the threaded rod and the adjustment seat can slide on the first sliding groove, that is, change the rotation radius of the adjustment seat, and then adjust the movement stroke of the pushing component. After adjustment, rotate the nut so that the nut and the adjustment seat are clamped on the rotating rod. When the motor is working, it drives the rotating rod to rotate, and the rotating rod drives the adjustment seat to rotate. The adjustment seat is fixed on the rotating rod and does not rotate itself. The adjustment seat and the rotating rod rotate around the motor shaft together to push the pushing component sleeved on the adjustment seat to move.

[0008] Specifically, the pushing assembly includes a limit seat fixed on the baffle, a connecting rod rotatably sleeved on the adjustment seat, and a push rod penetrating the limit seat and rotatably sleeved on the adjustment seat. The limit seat limits the push rod; the connecting rod is sleeved on the adjustment seat, and when the adjustment seat rotates around the motor shaft, it pushes the connecting rod to rotate, the connecting rod pushes the push rod to move, and the push rod pushes the shock absorber to compress.

[0009] Specifically, the detection mechanism includes a second slide groove fixed on the base, a third slide groove fixed on the base, a sensor slidably arranged on the second slide groove, and a scale plate slidably arranged on the third slide groove. The sensor can slide along the second slide groove to record the number of times the push rod is pushed. Since the sizes and strokes of different types of shock absorbers are different, in order to push different types of shock absorbers, the stroke of the push rod needs to be adjusted, and then the sensor also needs to be adjusted so that the sensor is aligned with the push rod head; the scale plate is provided with a scale, after the shock absorber is fixed, the zero scale is aligned with one end of the shock absorber, and after the test is completed, the scale at one end of the shock absorber is observed to determine whether the shock absorber is attenuated and the degree of attenuation.

[0010] The beneficial effects of the utility model are:

[0011] (1) The movement stroke of the driving component can be adjusted to adapt to different types of shock absorbers.

[0012] (2) The number of times the push component is pushed can be set to estimate the expansion and contraction life of the shock absorber.

[0013] (3) The scale plate allows you to visually see whether the shock absorber is attenuating and the degree of attenuation. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] When in use, fix the shock absorber to be tested on the fixing plate, and then fix the fixing plate on the fixing seat with screws. Set the number of tests through the second button, set the motor speed through the first button, slide the scale plate, align the zero scale with one end of the shock absorber, slide the sensor, and move the sensor to the middle of the shock absorber and the push rod, close to the shock absorber. Then loosen the nut, the threaded rod and the adjustment seat can slide on the first slide slot, that is, change the rotation radius of the adjustment seat, and then adjust the movement stroke of the push rod.
