Description

Technical Field

[0001] This invention relates to the field of pressure testing technology, and in particular to a pressure testing device for processing automotive shock absorbers. Background Technology

[0002] Automotive shock absorbers are core components of the automotive suspension system, belonging to vibration damping devices. Their main function is to attenuate vibrations caused by road impacts, improving ride comfort and handling safety. They convert mechanical energy into heat energy through hydraulic or gas damping, reducing resistance during the suspension's compression stroke to buffer impacts and increasing resistance during the extension stroke to suppress rebound, ensuring wheel grip. Currently, automotive shock absorbers are assembled on a workbench. Because of their critical role in automobiles, pressure testing is necessary before they leave the factory to ensure their performance.

[0003] Currently, when performing pressure testing on automotive shock absorbers, different types of shock absorbers are encountered. Since shock absorbers are available in different lengths for different car models, it is inconvenient to perform pressure testing on shock absorbers that are too long or too short, which affects the accuracy of the pressure test. Therefore, this invention proposes a pressure testing device for processing automotive shock absorbers. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing automotive shock absorbers, which come in different lengths for different car models. This makes it difficult to perform pressure testing on shock absorbers that are too long or too short, thus affecting the accuracy of pressure testing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pressure testing device for processing automotive shock absorbers, comprising a support base, an installation mechanism mounted on the support base, and a testing mechanism mounted on the support base, wherein the testing mechanism drives the installation mechanism to perform installation and testing of automotive shock absorbers; the testing mechanism comprises a slide rail, the slide rail being fixedly connected to one edge of the upper surface of the support base, and a motor being fixedly connected to the other edge of the upper surface of the support base, the output shaft of the motor being fixedly connected to a lead screw, and a connecting seat being rotatably mounted at one end of the lead screw, the connecting seat being fixedly connected to the upper surface of the support base.

[0006] In at least some embodiments, the mounting mechanism includes two sliders slidably mounted in a slide rail, with an inclined side plate fixed to one side of each slider, and a rotating shaft fixed to one side of the upper surface of the inclined side plate.

[0007] In at least some embodiments, a support plate is rotatably mounted on both of the two rotating shafts, an inclined side plate is fixedly connected to the upper end of each of the two support plates, and a mounting ring is fixedly connected to the upper surface of each of the two inclined side plates.

[0008] In at least some embodiments, a mating sleeve is engaged with the lead screw, a connecting block is fixedly connected above the surface of the mating sleeve, and a support rod is fixedly connected to one end of the connecting block.

[0009] In at least some embodiments, lower rollers are rotatably mounted at both ends of the support rod, the lower rollers are in close contact with the inner surface of the inclined side plate, and extension rods are fixedly connected to both ends of the outer wall of the support rod.

[0010] In at least some embodiments, one end of the extension rod extends to an inclined portion on one side of the inclined side plate, and an upper roller is rotatably mounted on the upper end of the extension rod, with the upper roller closely attached to the inclined portion on one side of the inclined side plate.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, starting the motor drives the lead screw to rotate. The motor provides driving force for the detection device and can also drive the installation mechanism to adjust the spacing, thus making it suitable for car shock absorbers of different lengths. When the lead screw rotates, it can drive the mating sleeve to move horizontally along the lead screw. At the same time, the support rod and the lower roller will also move horizontally with the mating sleeve. Since the support rod is fixed to the extension rod, the extension rod will move horizontally with the mating sleeve. The upper roller and the lower roller can contact the installation mechanism, thereby adjusting according to the length of the car shock absorber and performing pressure detection on the car shock absorber.

[0012] 2. In this invention, when the motor drives the upper and lower rollers to move horizontally, the lower roller contacts the inclined side plate, which in turn drives the slider to move horizontally along the slide rail, thereby adjusting the distance between the two mounting rings. This allows for positioning of car shock absorbers of different lengths. The upper roller contacts the inclined side plate, which in turn drives the mounting rings to rotate around the axis of rotation, thereby moving the two mounting rings to a parallel state. This allows the car shock absorber to be installed in the two mounting rings and enables pressure detection. Attached Figure Description

Detailed Implementation

[0015] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0017] In existing technology, automotive shock absorbers are core components of automotive suspension systems, belonging to vibration damping devices. Their main function is to attenuate vibrations caused by road impacts, improving ride comfort and handling safety. They convert mechanical energy into heat energy through hydraulic or gas damping, reducing resistance during the suspension compression stroke to buffer impacts and increasing resistance during the extension stroke to suppress rebound, ensuring wheel grip. Currently, automotive shock absorbers are assembled on a workbench. Because shock absorbers are crucial in automobiles, pressure testing is required before they leave the factory to ensure performance. However, pressure testing of shock absorbers involves various lengths available for different vehicle models. This makes pressure testing difficult with shock absorbers that are too long or too short, affecting the accuracy of the test results. Therefore, the present invention aims at least in that starting the motor 201 drives the lead screw 202 to rotate. The motor 201 provides driving force for the detection device and can also drive the mounting mechanism 300 to adjust the spacing, thus making it suitable for automotive shock absorbers of different lengths. When the lead screw 202 rotates, it drives the mating sleeve 203 to move horizontally along the lead screw 202. At the same time, the support rod 205 and the lower roller 207 also move horizontally with the mating sleeve 203. Since the support rod 205 is fixedly connected to the extension rod 206, the extension rod 206 will move horizontally with the mating sleeve 203. The upper roller 209 and the lower roller 207 can contact the mounting mechanism 300, thereby adjusting the spacing according to the length of the automotive shock absorber. The system adjusts and performs pressure testing on the car shock absorber. When the motor 201 drives the upper roller 209 and lower roller 207 to move horizontally, the lower roller 207 contacts the inclined side plate 303, which drives the slider 301 to move horizontally along the slide rail 210. This achieves the effect of adjusting the distance between the two mounting rings 306, allowing for positioning of car shock absorbers of different lengths. The upper roller 209 contacts the inclined side plate 305, which drives the mounting rings 306 to rotate around the rotation axis 302 via the inclined side plate 305. This causes the two mounting rings 306 to move to a parallel state, thereby enabling the car shock absorber to be installed in the two mounting rings 306 and for pressure testing.

[0018] Implementation examples, based on Figures 1-6 This invention provides a pressure testing device for processing automotive shock absorbers, comprising a support 100, an installation mechanism 300 mounted on the support 100, and a testing mechanism 200 mounted on the support 100. The testing mechanism 200 drives the installation mechanism 300 to perform installation and testing of the automotive shock absorber. Figure 5 As shown, the detection mechanism 200 includes a slide rail 210, which is fixed to one edge of the upper surface of the support 100. A motor 201 is fixed to the other edge of the upper surface of the support 100. A lead screw 202 is fixed to the output shaft of the motor 201. A connecting seat 211 is rotatably mounted on one end of the lead screw 202. The connecting seat 211 is fixed to the upper surface of the support 100. Starting the motor 201 can drive the lead screw 202 to rotate. The motor 201 can provide driving force for the detection device and can also drive the mounting mechanism 300 to adjust the spacing, thus making it suitable for automobile shock absorbers of different lengths.

[0019] like Figure 4As shown, the mounting mechanism 300 includes two sliders 301, which are slidably mounted in the slide rail 210. An inclined side plate 303 is fixedly connected to one side of each slider 301. A rotating shaft 302 is fixedly connected to one side of the upper surface of each inclined side plate 303. Support plates 304 are rotatably mounted on each of the two rotating shafts 302. An inclined side plate 305 is fixedly connected to the upper end of each of the two support plates 304. A mounting ring 305 is fixedly connected to the upper surface of each of the two inclined side plates 305. When the motor 201 drives the upper roller 209 and the lower roller 207 to move horizontally... The lower roller 207 contacts the inclined side plate 303, which drives the slider 301 to move horizontally along the slide rail 210, thereby adjusting the distance between the two mounting rings 306. This allows for positioning of car shock absorbers of different lengths. The upper roller 209 contacts the inclined side plate 305, which drives the mounting rings 306 to rotate around the rotation axis 302, thereby moving the two mounting rings 306 to a parallel state. This allows the car shock absorber to be installed in the two mounting rings 306 and performs pressure detection.

[0020] like Figures 5-6 As shown, a fitting sleeve 203 is engaged with the lead screw 202. A connecting block 204 is fixedly connected above the surface of the fitting sleeve 203. A support rod 205 is fixedly connected to one end of the connecting block 204. Lower rollers 207 are rotatably mounted on both ends of the support rod 205. The lower rollers 207 are in close contact with the inner surface of the inclined side plate 303. Extension rods 205 are fixedly connected to both ends of the outer wall of the support rod 205. One end of the extension rod 205 extends to the inclined side plate 303. An upper roller 209 is rotatably mounted on the upper end of the extension rod 205. The upper roller 209 is close to the inclined side plate 303. When the lead screw 202 rotates, it can drive the mating sleeve 203 to move horizontally along the lead screw 202. At the same time, the support rod 205 and the lower roller 207 will also move horizontally with the mating sleeve 203. Since the support rod 205 is fixedly connected to the extension rod 206, the extension rod 206 will move horizontally with the mating sleeve 203. The upper roller 209 and the lower roller 207 can contact the mounting mechanism 300, thereby adjusting according to the length of the car shock absorber and performing pressure testing on the car shock absorber.

[0021] The working principle of this invention is as follows: Starting the motor 201 drives the lead screw 202 to rotate. The motor 201 provides driving force to the detection device and also drives the mounting mechanism 300 to adjust the spacing, thus adapting to automotive shock absorbers of different lengths. When the lead screw 202 rotates, it drives the mating sleeve 203 to move horizontally along the lead screw 202. Simultaneously, the support rod 205 and the lower roller 207 also move horizontally with the mating sleeve 203. Since the support rod 205 is fixedly connected to the extension rod 206, the extension rod 206 moves horizontally along with the mating sleeve 203. Through the upper roller 209 and the lower roller 207, it can contact the mounting mechanism 300, thereby adjusting the spacing according to the length of the automotive shock absorber. The device performs pressure testing on the car shock absorber. When the motor 201 drives the upper roller 209 and the lower roller 207 to move horizontally, the lower roller 207 contacts the inclined side plate 303, which drives the slider 301 to move horizontally along the slide rail 210. This achieves the effect of adjusting the distance between the two mounting rings 306. It can position car shock absorbers of different lengths. Then, the upper roller 209 contacts the inclined side plate 305, which drives the mounting rings 306 to rotate around the rotation axis 302. This moves the two mounting rings 306 to a parallel state, thus installing the car shock absorber in the two mounting rings 306 and performing pressure testing.
