Description

Technical Field

[0001] This utility model belongs to the field of automotive parts testing technology, and specifically relates to a semi-automatic torque testing device for the end of an active shock absorber. Background Technology

[0002] Active shock absorbers are a core component of modern automotive suspension systems, and the torque performance of their end connectors is crucial, directly affecting driving safety and comfort. Currently, torque testing of shock absorber ends is mostly performed using manual or fully manual fixtures.

[0003] Manual method: The operator uses a torque wrench to directly tighten or rotate the workpiece for testing. This method relies entirely on manual labor, is inefficient, and the test results are greatly affected by human factors (such as the angle of force, speed, and fatigue), resulting in poor repeatability, difficulty in guaranteeing data accuracy, and certain safety risks.

[0004] Fully automated method: This method uses industrial robots in conjunction with high-precision torque sensors and vision systems. It is extremely expensive, the equipment is complex, and maintenance is difficult. It is usually only suitable for production lines with large batches of single-model products. It lacks flexibility for R&D or quality inspection of multiple varieties and small batches, and has a low cost-performance ratio.

[0005] In summary, manual testing suffers from low efficiency, high labor intensity, and significant susceptibility to human error in accuracy and repeatability. Fully automated testing, on the other hand, is costly and lacks flexibility. A testing solution that balances efficiency, accuracy, cost, and ease of operation is currently lacking.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0028] like Figure 1-9 As shown, this utility model provides a semi-automatic torque testing device for the end of an active shock absorber, which includes: a stand 110, a mounting base 120, a first positioning base 130, a second positioning base 140, a first clamping mechanism 150, a second clamping structure 160, a bracket 170, a lifting mechanism 180, and a digital torque wrench 190.

[0029] The platform 110 has a horizontally positioned tabletop, and the mounting base 120 is fixedly mounted on the platform 110. The platform 110 serves as the supporting foundation for the entire fixture and is constructed from welded profiles or steel plates to ensure overall rigidity and stability. In this embodiment, the mounting base 120 includes a base plate 121 and a mounting base upright plate 122. The base plate 121 is parallel to the tabletop of the platform 110 and is fixedly connected to the tabletop of the platform 110 by bolts. The lower end of the mounting base upright plate 122 is fixedly connected to the base plate 121, and the mounting base upright plate 122 is vertically positioned and perpendicular to the base plate 121.

[0030] The first positioning seat 130 is bolted to the lower part of the mounting base 120. The bottom of the first positioning seat 130 abuts against the base plate 121, and one side abuts against the mounting base upright plate 122. The first positioning seat 130 has a first positioning groove 131. The first positioning groove 131 is a U-shaped groove with its opening facing away from the mounting base upright plate 122, and the size of the first positioning groove 131 matches the outer diameter of the shock absorber workpiece 200 (lower end) to be tested.

[0031] The second positioning seat 140 is bolted to the upper part of the mounting base 120, that is, the second positioning seat 140 is located above the first positioning seat 130; the second positioning seat 140 has a second positioning groove 141. The second positioning groove 141 is a U-shaped groove with its opening facing away from the mounting base upright plate 122, and the size of the second positioning groove 141 matches the outer diameter of the shock absorber workpiece 200 (upper end) to be tested. The center positions of the second positioning groove 141 and the first positioning groove 131 are aligned in the vertical direction.

[0032] The lower end of the shock absorber workpiece 200 to be tested is placed in the first positioning groove 131, and the upper end is placed in the second positioning groove 141. The distance from the top of the mounting base 120 to the top of the second positioning base 140 is less than the length of the shock absorber workpiece 200 to be tested, so that the end of the shock absorber workpiece 200 is located above the second positioning groove 141.

[0033] The first clamping mechanism 150 is detachably installed on one side of the first positioning seat 130. A first clamping block 151 is installed on the moving end of the first clamping mechanism 150, and the lower end of the shock absorber workpiece 200 is fixed in the first positioning groove 131 by the first clamping block 151.

[0034] In this embodiment, the first clamping mechanism 150 is a compact cylinder. The first clamping mechanism 150 is mounted on the left side of the first positioning seat 130 via a first cylinder mounting base 152. The first clamping block 151 is connected to the piston rod of the first clamping mechanism 150. A first slide rail 132 is provided in the first positioning seat 130 along its length direction. The first slide rail 132 is parallel to the table surface of the frame 110. The length direction of the first slide rail 132 is perpendicular to the central axis of the first positioning groove 131 (U-shaped groove), and the first slide rail 132 communicates with the first positioning groove 131. The first clamping block 151 is matched and disposed in the first slide rail 132. The first clamping block 151 is a V-shaped block (the clamping end is V-shaped). The first clamping mechanism 150 can drive the first clamping block 151 to reciprocate along the first slide rail 132, so that the first clamping block 151 moves into the first positioning groove 131 and abuts against one side of the shock absorber workpiece 200, thereby fixing the shock absorber workpiece 200 in the first positioning groove 131 and preventing the shock absorber workpiece 200 from moving or rotating during testing. In this embodiment, when the rod chamber of the first clamping mechanism 150 (cylinder) is supplied with air, the cylinder retracts, and at this time the first clamping block 151 (V-block) also retracts. When the rodless chamber of the first clamping mechanism 150 (cylinder) is supplied with air, it drives the first clamping block 151 (V-block) to push out and clamp the lower part of the shock absorber workpiece 200.

[0035] The second clamping mechanism 160 is detachably mounted on the second positioning seat 140, and the second clamping mechanism 160 is arranged on the same side as the first clamping mechanism 150. A second clamping block 161 is mounted on the moving end of the first clamping mechanism 160, and the upper end of the shock absorber workpiece 200 is fixed in the second positioning groove 141 by the second clamping block 161.

[0036] In this embodiment, the second clamping mechanism 160 employs a compact cylinder. The second clamping mechanism 160 is mounted on the left side of the second positioning seat 140 via a second cylinder mounting base 162. The second clamping block 161 is connected to the piston rod of the second clamping mechanism 160. A first slide rail 142 is formed along the length of the second positioning seat 140, parallel to the surface of the platform 110. The length of the second slide rail 142 is perpendicular to the central axis of the second positioning groove 141 (U-shaped groove), and the second slide rail 142 communicates with the second positioning groove 141. The second clamping block 161 is matched and disposed within the second slide rail 142, and the second clamping block 161 is a V-shaped block (with a V-shaped clamping end). The second clamping mechanism 160 can drive the second clamping block 161 to reciprocate along the second slide rail 142, so that the second clamping block 161 moves into the second positioning groove 141 and abuts against one side of the shock absorber workpiece 200, thereby fixing the shock absorber workpiece 200 in the first positioning groove 141 and preventing the shock absorber workpiece 200 from moving or rotating during testing. In this embodiment, when the rod chamber of the second clamping mechanism 160 (cylinder) is supplied with air, the cylinder retracts, and at this time the second clamping block 161 (V-block) also retracts. When the rodless chamber of the second clamping mechanism 150 (cylinder) is supplied with air, it drives the second clamping block 161 (V-block) to push out and clamp the upper part of the shock absorber workpiece 200.

[0037] The lifting mechanism 180 is fixed above the mounting base 120, and a digital torque wrench 190 is mounted on the moving end of the lifting mechanism 180. The lifting mechanism 180 can drive the digital torque wrench 190 to move up and down. When the digital torque wrench 190 moves down to the end of the shock absorber workpiece 200 to be tested, the sleeve of the digital torque wrench 190 engages with the end of the shock absorber workpiece 200.

[0038] In this embodiment, the lifting mechanism 180 is fixedly mounted on the mounting base 120 via a bracket 170. The bracket 170 includes a bracket upright plate 171 and a top plate 172; the lower end of the bracket upright plate 171 is fixedly connected to the mounting base upright plate 122, and the bracket upright plate 171 and the mounting base upright plate 122 are arranged parallel to each other; the top plate 172 is fixedly mounted on the upper end of the bracket upright plate 171 and is parallel to the bottom plate 121.

[0039] The lifting mechanism 180 employs a lifting cylinder, the base of which is fixedly installed on the lower side of the top plate 172. The lifting cylinder is vertically positioned, with its piston rod coaxially aligned with the shock absorber workpiece 200 to be tested, and the moving end of the piston rod facing the end of the shock absorber workpiece 200. In this embodiment, when air is supplied to the rod chamber of the lifting cylinder, it drives the digital torque wrench 190 upward; when air is supplied to the rodless chamber of the lifting cylinder, it drives the digital torque wrench 190 and the sleeve downward together into the internal hexagonal hole at the end of the shock absorber workpiece 200.

[0040] The digital torque wrench 190 is fixedly connected to the piston rod of the lifting cylinder by bolts. The sleeve of the digital torque wrench 190 is coaxially arranged with the piston rod of the lifting cylinder.

[0041] In this embodiment, both the first positioning seat 130 and the second positioning seat 140 are made of aluminum alloy. The cross-sections of the first slide rail 132 and the second slide rail 142 are both rectangular, and the cross-sectional dimensions of the first slide rail 132 and the second slide rail 142 are both 24mm × 20mm.

[0042] As a preferred embodiment, a nylon bushing 143 is detachably mounted in the second positioning seat 140, and a second positioning groove 141 is formed in the nylon bushing 143. Correspondingly, the nylon bushing 143 also has a slide rail of the same size that communicates with the second slide rail 142. The nylon bushing 143 reduces bumps and scratches on the shock absorber workpiece 200.

[0043] This utility model uses a lifting mechanism 180 to drive a digital torque wrench 190 to move up and down. In the "standby" position, the torque wrench is away from the clamping area, making it convenient for the operator to load and unload materials; in the "test" position, the cylinder moves downward, so that the end clamp (external hexagonal sleeve) engages with the end of the shock absorber workpiece.

[0044] The specific working process of the semi-automatic torque testing device for the end of the active shock absorber provided by this utility model is as follows: The operator places the lower end of the shock absorber workpiece to be tested into the first positioning groove 131 and the upper end into the second positioning groove. The first clamping mechanism 150 and the second clamping mechanism 160 respectively drive the first clamping block 151 and the second clamping block 161 to move and position and clamp the upper and lower ends of the shock absorber workpiece 200. The lifting mechanism 180 drives the digital torque wrench 190 to move downward, so that the outer hexagonal socket of the digital torque wrench 190 enters the inner hexagonal hole of the end of the shock absorber workpiece and engages. The pre-designed torque of the wrench is 70 N.M. The operator manually twists the digital torque wrench 190 until the torque reaches the preset value and a buzzer alarm sounds. The first clamping mechanism 150, the second clamping mechanism 160 and the lifting mechanism 180 return to the initial (standby) position, the shock absorber workpiece is taken out, and one work cycle is completed.

[0045] This invention provides a compact, easy-to-operate, cost-effective, high-precision, and repeatable semi-automatic torque testing device for active shock absorber ends. It combines manual loading and unloading with automatic loading testing, significantly improving testing efficiency and reducing operator workload while ensuring test quality. By changing the end clamp (external hexagonal sleeve) and adjusting the clamping mechanism, this invention can quickly adapt to testing different models of shock absorber ends, demonstrating strong versatility. Compared to fully automated production lines, costs are significantly reduced; compared to purely manual testing, the long-term benefits (efficiency, quality, and data management) are outstanding.

[0046] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
