Description

Technical Field

[0001] This invention relates to the field of hardness testing equipment technology, specifically to a hardness testing device for a shock absorber dust cover. Background Technology

[0002] Shock absorber dust boots are a crucial component of automotive suspension systems. Like a protective shield, they encase the shock absorber piston rod, effectively preventing mud, dust, gravel, and moisture from entering the shock absorber and extending its lifespan. The dust boots utilize a corrugated rubber structure, absorbing some minor vibrations during vehicle operation, reducing rigid collisions between metal parts, and improving ride comfort. Especially in low-temperature environments, they prevent the buffer rubber from hardening and causing abnormal noises. Dust boots are typically made of rubber or elastomer materials, and their hardness directly affects wear resistance, resilience, sealing performance, and temperature stability. The core purpose of hardness testing is to assess the material's aging degree, manufacturing process consistency, and durability in real-world usage environments. After processing and molding, the shock absorber dust boots require hardness testing equipment to verify their hardness.

[0003] During the demolding process of the dust cover for shock absorbers, a release agent will adhere to its surface. During testing, this release agent can easily adhere to the test head of the hardness testing equipment, leading to lower measured values ​​or data fluctuations, thus affecting the accuracy of the test. During the testing process, the release agent on the test points needs to be wiped clean manually. Since there are many test points selected during hardness testing, the cleaning process is time-consuming and labor-intensive. In addition, the corrugated surface of the dust cover is curved, and the test position at the trough is narrow, making it easy for release agent residue to remain during the wiping process, which in turn affects the test results. Summary of the Invention

[0004] This invention provides a hardness testing device for shock absorber dust covers. It features automatic cleaning capabilities and, with the assistance of two levers, can stretch the corrugated section testing area of ​​the dust cover. This facilitates the wiping block to clean and absorb the release agent on the corrugated section testing area, reducing wiping dead angles and improving the release agent wiping effect. This improves the hardness testing accuracy of the hardness tester for the corrugated section of the dust cover. It solves the problem mentioned in the background art where manual wiping of the release agent from the testing points is required during the testing process. Due to the large number of testing points selected during hardness testing, cleaning is time-consuming and labor-intensive. Furthermore, the corrugated surface of the dust cover is curved, and the testing area at the troughs is narrow, making it easy for release agent residue to remain during wiping, thus affecting the test results.

[0015] The present invention has the following beneficial effects:

[0016] 1. In this shock absorber dust cover hardness testing equipment, the mounting rod on the testing table provides support during the dust cover testing process. The clamping block is used to fix one end of the dust cover to the mounting rod, preventing displacement of the dust cover during testing. The electric slide can adjust the testing position of the hardness tester, and the second electric push rod can adjust the height of the hardness tester, so that the testing end can apply a certain pressure to the testing surface of the dust cover. The hardness value can be calculated by measuring the depth of the indenter. The mounting bracket of the moving end of the electric slide can move horizontally synchronously with the hardness tester, causing the wiping seat to move below the testing area of ​​the dust cover. When the first servo motor drives the mounting rod to rotate, it is convenient for the wiping block in the wiping seat to move up and contact the surface of the dust cover testing area, so as to clean the mold release agent on its surface and improve the accuracy of the hardness tester in testing the hardness of the dust cover. When the electric slide moves the hardness tester to the flat surfaces at both ends of the dust cover for hardness testing, the wiping seat moves synchronously, and the sealing cover opens accordingly. When the hardness tester moves down for testing, it causes the second contact strip to contact the first contact bracket, which in turn causes the second contact head to contact the first contact wedge. This causes the wiping block to automatically move up and fit against the circumferential surface of the dust cover. When the mounting rod rotates the dust cover, it is convenient to wipe and absorb the release agent adhering to the test area. This allows the hardness tester to perform multi-point testing on the test area after the release agent has been wiped off, which can improve the accuracy of hardness testing.

[0017] 2. In this shock absorber dust cover hardness testing equipment, a rotatable guide rod can drive two pull rods to deflect, allowing the two pull rods to be inserted into the troughs of the corrugated section of the dust cover. The two pull rods move synchronously in opposite directions, which can stretch the testing area of ​​the corrugated section of the dust cover, making the surface flat. This facilitates the wiping block to wipe and absorb the release agent on the testing area of ​​the corrugated section of the dust cover, reduces wiping dead corners, improves the wiping effect of the release agent, and improves the hardness testing accuracy of the hardness tester for the corrugated section of the dust cover. When the first contact support is moved by the contact, it causes the second contact wedge to contact the contact rod, causing the conical contact head to move down and simultaneously contact one end of the two pull rods. This causes the pull rods to move on the guide rod. On the one hand, this allows the dust cover corrugated section detection area to be in a stretched state, facilitating the wiping of the release agent. After the pull rods are reset, the detection is performed to improve the detection accuracy of this area. On the other hand, when the hardness tester moves up and down, it causes the pull rods to move back and forth on the guide rod, allowing for dynamic reciprocating stretching of the dust cover corrugated section detection area. This enables fatigue testing of the dust cover corrugated section detection area. When the hardness is measured again at the same location, it is possible to analyze whether the material has hardened or softened, thereby determining the long-term performance degradation trend.

[0018] 3. In this shock absorber dust cover hardness testing equipment, several rinsing nozzles inside the wiping seat can spray the treatment liquid onto the surface of the wiping block to quickly remove the residual release agent oil film on the surface of the wiping block, making it convenient for the next use of the wiping block. Through the cooperation of the rotating shaft, the third contact strip, the second contact bracket and the third contact head, during the dynamic reciprocating stretching of the dust cover, when the conical contact head moves down, it drives the first contact strip to contact the third contact head, causing the rinsing nozzle to deflect and reduce the rinsing dead angle. At the same time, when the first contact bracket moves back and forth, it can drive the second contact head to contact the first contact wedge, causing the filter mounting plate to move the wiping block up and press against the closed sealing cover plate, which can achieve the purpose of automatic reciprocating squeezing of the wiping block, so that the squeezed release agent and treatment liquid fall into the bottom of the wiping seat, improving the dryness of the wiping block and the adsorption effect of the release agent for the next use.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1, please refer to Figures 1 to 8A hardness testing device for a shock absorber dust cover includes a testing platform 1, a mounting rod 2 rotatably connected to the testing platform 1, an electric slide 3 fixed above the testing platform 1, a mounting bracket 4 fixed to the moving end of the electric slide 3, a liftable hardness tester 5 provided below the moving end of the electric slide 3, a second abutment strip 16 fixed to one side of the hardness tester 5, a wiping seat 6 fixed to the lower end of the mounting bracket 4, a liftable wiping block 7 provided inside the wiping seat 6, and a first abutment bracket 8 slidably connected to the mounting bracket 4. One side of the mounting bracket 4 is provided with a rotatable guide rod 9, and two pull rods 10 are slidably connected on the guide rod 9. A conical contact head 11 is provided above the pull rod 10.

[0030] A first servo motor 12 is fixed on the testing table 1. The motor shaft of the first servo motor 12 is fixedly connected to one end of the mounting rod 2. A first electric push rod 13 is fixed on the circumferential surface of one end of the mounting rod 2. A clamping block 14 is fixed on the piston rod of the first electric push rod 13.

[0031] A second electric push rod 15 is fixed on the moving end of the electric slide table 3. The lower end of the piston rod of the second electric push rod 15 is fixedly connected to the hardness tester 5. A first spring 17 is connected between the first contact bracket 8 and the mounting bracket 4.

[0032] A filter mounting plate 18 is fixed to the lower end of the wiping block 7. The filter mounting plate 18 is elastically connected to the wiping seat 6 through the second spring 19. A first abutting wedge 20 is fixed below the filter mounting plate 18. A second abutting head 21 abuts against the first abutting wedge 20. The second abutting head 21 is slidably connected to the wiping seat 6, and one end of the second abutting head 21 is fixedly connected to the first abutting bracket 8.

[0033] The wiping seat 6 has a sealing cover 22 at its opening, and a third electric push rod 23 is fixed on the wiping seat 6. The piston rod of the third electric push rod 23 is fixedly connected to the sealing cover 22.

[0034] refer to Figures 1 to 7 When the dust cover of the shock absorber is formed and hardness is tested, the dust cover is installed on the mounting rod 2. The piston rod of the first electric push rod 13 extends and drives the clamping block 14 to move, fixing one end of the dust cover on the mounting rod 2. The first servo motor 12 on the test table 1 drives the mounting rod 2 and the dust cover to rotate synchronously. The moving end of the electric slide table 3 moves horizontally, driving the hardness tester 5 to move towards the end of the dust cover, so that the test end is aligned with the flat test surface at its end. When the piston rod of the second electric push rod 15 initially extends, the hardness tester 5 moves down, causing the second contact strip 16 fixed on one side of the hardness tester 5 to contact the first contact bracket 8, so that the first contact bracket 8 slides horizontally on the mounting bracket 4, the first spring 17 stores force, and one end of the first contact bracket 8 drives the second contact head 21 to slide in the wiping seat 6 and contact the first contact wedge 20, so that the filter mounting plate 18 drives the wiping block 7 to move upward, the second spring 19 stores force, and at the same time, the piston rod of the third electric push rod 23 on the wiping seat 6 extends, causing the sealing cover plate 22 to move horizontally, opening the wiping seat 6, so that the wiping block 7 moves upward and abuts against the test surface of the dust cover. During the rotation of the dust cover, the wiping block 7 can wipe and absorb the release agent attached to its test surface, reduce residue, and improve the accuracy of hardness testing; After cleaning, the dust cover stops rotating so that the hardness tester 5 can continue to move down. The testing end can apply a certain pressure to the testing surface of the dust cover. The hardness value can be calculated by measuring the depth of the indenter. The rotation angle of the dust cover can be controlled by the first servo motor 12 so that the hardness tester 5 can test the dust cover at multiple points.

[0035] Example 2 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1 to 8 A mounting base 24 is fixed on one side of the mounting bracket 4. One end of the guide rod 9 is rotatably connected to the mounting base 24, and a second servo motor 25 is fixed on the mounting base 24. The motor shaft of the second servo motor 25 is fixedly connected to the guide rod 9. Two third springs 26 are fixed on the guide rod 9, and one end of the two third springs 26 is fixedly connected to two pull rods 10 respectively.

[0036] A contact rod 27 is fixed on the conical contact head 11. The contact rod 27 is elastically connected to the mounting bracket 4 through the fourth spring 28, and a first contact strip 29 is fixed at the lower end of the conical contact head 11.

[0037] One end of the first contact bracket 8 is provided with a first contact slope 30 and a second contact slope 31. The second contact slope 31 is located below the first contact slope 30, and the contact rod 27 abuts against a second contact wedge 32. The second contact wedge 32 is fixed on the first contact bracket 8.

[0038] refer to Figures 1 to 7When the hardness tester 5 performs multi-point testing on the troughs of the corrugated section of the dust cover, it is also necessary to wipe the release agent on the troughs. Due to the narrowness of the test troughs, it is inconvenient for the wiping block 7 to extend in, so the corrugated section of the dust cover needs to be stretched. At this time, the sealing cover 22 is in the reset state to avoid obstructing the deflection of the pull rod 10. The electric slide 3 drives the hardness tester 5 to move above the corrugated section of the dust cover, and the test end of the hardness tester 5 is aligned with the trough of the corrugated section of the dust cover. The second servo motor 25 on the mounting base 24 drives the guide rod 9 to rotate, causing the two pull rods 10 on the guide rod 9 to deflect and engage with the test rod. Within two adjacent troughs, the hardness tester 5 moves downward, which enables the second contact strip 16 to contact the first contact slope 30 of the first contact bracket 8, causing the first contact bracket 8 to drive the second contact wedge 32 to move horizontally and contact the contact rod 27. The first spring 17 initially stores force, and after the contact rod 27 is contacted, it drives the conical contact head 11 to move downward. The fourth spring 28 stores force, so that the conical contact head 11 contacts the movement of the two pull rods 10, so that the two pull rods 10 move synchronously in opposite directions on the guide rod 9. The third spring 26 stores force, so as to stretch the surface below the detection area of ​​the dust cover corrugated section, making the surface flat. When the second contact strip 16 contacts the second contact slope 31, the first spring 17 continues to store force. At this time, the sealing cover 22 opens so that the wiping block 7 moves up and abuts against the surface of the stretched corrugated section of the dust cover. When the dust cover rotates, it is convenient to wipe the release agent on the detection area, reduce the wiping dead angle, improve the wiping effect of the release agent and the detection quality of the hardness tester 5. After cleaning, the pull rod 10 is reset so that the trough of the corrugated section of the dust cover returns to its original state, so as to avoid affecting the accuracy of the hardness test results. When conducting fatigue tests on the corrugated section of the dust cover, the two pull rods 10 are engaged in the two adjacent troughs of the test trough. The second electric push rod 15 can drive the hardness tester 5 to move down reciprocally, causing the second contact strip 16 to reciprocate against the first contact slope 30 of the first contact bracket 8, so that the test area of ​​the corrugated section of the dust cover can be dynamically stretched. This achieves the purpose of conducting fatigue tests on the test area of ​​the corrugated section of the dust cover. When the hardness at the same location is measured again, it can be analyzed whether the material has hardened or softened, so as to determine the long-term performance degradation trend of the corrugated section.

[0039] Example 3 is an improvement upon Example 2. For details, please refer to [link / reference]. Figures 1 to 8 The wiping seat 6 is provided with several rinsing nozzles 33. The lower end of the rinsing nozzle 33 is fixed with a rotating shaft 34. The rotating shaft 34 is rotatably connected to the wiping seat 6, and a third contact strip 35 is fixed on the rotating shaft 34.

[0040] The wiping seat 6 is provided with a second contact bracket 36, and the second contact bracket 36 is provided with an i-shaped groove 37. One end of the third contact strip 35 is located in the i-shaped groove 37, and a third contact head 38 is fixed to one end of the second contact bracket 36. The third contact head 38 is elastically connected to the wiping seat 6 through a fifth spring 39.

[0041] refer to Figures 1 to 8 After use, the wiping block 7 needs to be cleaned for future use. When the detection area of ​​the corrugated section of the dust cover is dynamically stretched, the rinsing nozzle 33 is connected to the rinsing equipment to spray anhydrous ethanol treatment solution onto the surface of the wiping block 7, thereby removing the release agent and improving the performance of the wiping block 7. When the conical contact head 11 moves down, it can drive the first contact strip 29 to contact the third contact head 38, causing the second contact bracket 36 to move back and forth in the wiping seat 6. The fifth spring 39 continuously stores and releases its elasticity so that the third contact strip 35 located in the i-shaped groove 37, as the second contact bracket 36 moves horizontally back and forth, drives the rotating shaft 34 to move in the wiping seat 6. The wiping seat 6 deflects inward, causing the rinsing nozzle 33 to deflect synchronously, thereby reducing the rinsing dead angle and achieving the purpose of removing the residual mold release agent oil film on the wiping block 7. At this time, the sealing cover 22 is in a closed state. When the first contact bracket 8 slides horizontally on the mounting bracket 4, it can drive the second contact head 21 to contact the first contact wedge block 20, so that the filter mounting plate 18 drives the wiping block 7 to move up to a certain height, so that the wiping block 7 can press against the sealing cover 22, which can achieve the purpose of automatic reciprocating squeezing of the wiping block 7, so that the squeezed mold release agent and treatment liquid fall into the bottom of the wiping seat 6, improving the dryness of the wiping block 7 and the adsorption effect of the mold release agent for the next use.

[0042] The electric slide 3, hardness tester 5, first servo motor 12, first electric push rod 13, second electric push rod 15, third electric push rod 23 and second servo motor 25 are all electrically connected to the controller via wires.
