Description

Technical Field

[0001] The utility model relates to the technical field of automotive shock absorbers, in particular to the electrode test of automotive shock absorbers. Background Technique

[0002] In the new energy vehicle industry, automotive shock absorbers are assembled using an automated production line. Due to frequent production line changeovers, if the tooling needs to be replaced and debugged each time there is a changeover, it will greatly increase the changeover time, reduce production efficiency, and there is a possibility of scrapping the first batch of debug samples, increasing production costs. Compatible tooling can achieve rapid changeovers on the automated production line and ensure stable performance and convenient maintenance.

[0003] Figure 1 As shown in the front left type shock absorber, the shock absorber includes a body 61 and an electrode 62. Since it is necessary to test the continuity of the shock absorber electrode to determine whether the product is qualified, in order to make a production line compatible with the assembly of different models of shock absorbers, it is necessary to optimize the design of the tooling for loading and placement, which can at least meet the placement and electrode continuity testing of the existing four models of shock absorbers (front left type, front right type, rear left type, rear right type). Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to design an electrode test device for automotive shock absorbers that can meet the electrode tests of different models of shock absorbers in view of the defects existing in the prior art.

[0005] The utility model solves the above technical problems through the following technical solutions: An electrode test device for automotive shock absorbers includes a detection table, a clamping mechanism, a calibration mechanism, a probe test mechanism, and a photoelectric detection mechanism. The clamping mechanism, calibration mechanism, probe test mechanism, and photoelectric detection mechanism are all fixed on the detection table. The calibration mechanism is located between the clamping mechanism and the probe test mechanism. The probe test mechanism pushes the probe vertically into the shock absorber electrode. Support platforms are respectively fixed on both sides of the probe test mechanism. One end of the support platform is fixed on the detection table, and the other end of the support platform is V-shaped or U-shaped. A guide seat is fixed between the clamping mechanism and the support platform.

[0006] The utility model can place and test shock absorbers of different models. When the optoelectronic detection mechanism detects the presence of a shock absorber, the clamping mechanism clamps and fixes the electrode, and the correction mechanism corrects and finely adjusts the position of the end of the electrode, making the electrode parallel to the detection table. The probe testing mechanism pushes the probe in the vertical direction to closely contact the electrode, triggering the detection sensor. If the detection sensor is triggered and conducts, it is determined that the shock absorber is qualified; if the detection sensor does not conduct, it is determined that the shock absorber is unqualified. If the model of the shock absorber to be tested changes, only by reversing the direction of the shock absorber or rotating the shock absorber so that the electrode of the shock absorber can pass through the guiding seat, the on-off test of the shock absorber electrode can still be achieved. The probe testing mechanism pushes the probe into the shock absorber electrode in the vertical direction, which can avoid the problem of probe damage caused by probe floating.

[0007] The support table can be set in a V shape or a U shape, both of which can stably place the shock absorber. To better fix the shock absorber, the support table can be set in a V shape. Under the action of gravity, the shock absorber will be stuck in the V-shaped groove and its position will not shift.

[0008] Preferably, the clamping mechanism includes a first cylinder assembly, a first slider, and a first jaw. There is a chute in the first cylinder assembly, the first slider is located in the chute, and the first jaw is fixed on the first slider.

[0009] Preferably, the guiding seat includes a guiding hole and supporting ears on both sides of the guiding hole. The first side of the guiding hole fits with the side of the first jaw, and the second side of the guiding hole fits with the body of the shock absorber.

[0010] Preferably, there is a first groove on the first slider, and a first convex block at the end of the first jaw. The first convex block is clamped in the first groove.

[0011] Preferably, the end of the first jaw is in an arc shape, matching the profile of the shock absorber electrode, and a polyurethane gasket is also installed at the end of the first jaw.

[0012] Preferably, a throttle valve is installed at the air inlet and outlet of the first cylinder assembly.

[0013] By adjusting the air intake and exhaust of the cylinder through the throttle valve, the speed and tension when the first jaw clamps or releases can be controlled, and the problem that the probe cannot be sent in place due to the vibration driving the shock absorber to tilt when the first jaw clamps or releases caused by the air pressure being too large or unstable can be avoided.

[0014] Preferably, the correction mechanism includes a second cylinder assembly, a second slider, and a second jaw. There is a chute in the second cylinder assembly, the second slider is located in the chute, and the second jaw is fixed on the second slider.

[0042] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the following describes the technical solutions of the present utility model clearly and completely in combination with specific embodiments and with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0043] As Figure 2-3 shown, this embodiment provides an electrode testing device for an automotive shock absorber, which includes a detection table 10, a clamping mechanism 20, a calibration mechanism 30, a probe testing mechanism 40, and a photoelectric detection mechanism 50. The clamping mechanism 20, the calibration mechanism 30, the probe testing mechanism 40, and the photoelectric detection mechanism 50 are all fixed on the detection table 10. The calibration mechanism 30 is located between the clamping mechanism 20 and the probe testing mechanism 40. The probe testing mechanism 40 pushes the probe into the shock absorber electrode in the vertical direction. Support platforms 11 are respectively fixed on both sides of the probe testing mechanism 40. One end of the support platform 11 is fixed on the detection table 10, and the other end of the support platform 11 is V-shaped or U-shaped. A guiding seat 12 is fixed between the clamping mechanism 20 and the support platform 11.

[0044] Referring to Figure 1-3 , the other end of the support platform 11 in this embodiment is V-shaped. During actual operation, the body 61 of the shock absorber 60 is placed on the two V-shaped support platforms 11, and the electrode 62 of the shock absorber 60 passes through the guiding seat 12 and faces the calibration mechanism 30. Under the action of gravity, the shock absorber will be stuck in the V-shaped groove and its position will not shift, which can play a good fixing role. When the photoelectric detection mechanism 50 detects the presence of the shock absorber 60, the clamping mechanism 20 clamps and fixes the electrode 62 of the shock absorber 60. The calibration mechanism 30 corrects and finely adjusts the position of the end of the electrode 62 to make the electrode 62 parallel to the detection table 10. The probe testing mechanism 40 pushes the probe in the vertical direction to make close contact with the electrode 62, triggering the detection sensor. If the detection sensor is triggered and conducts, it is determined that the shock absorber is qualified; if the detection sensor does not conduct, it is determined that the shock absorber is unqualified. If the model of the shock absorber to be tested changes, only by reversing the direction of the shock absorber or rotating the shock absorber so that the electrode of the shock absorber can pass through the guiding seat, the on-off test of the shock absorber electrode can still be realized, thereby meeting the electrode testing of shock absorbers of different models.

[0045] As Figure 4As shown, the guiding base 12 includes a guiding hole 121 and supporting lugs 122 located on both sides of the guiding hole 121. Mounting holes are provided on the supporting lugs 122. When the body 61 of the shock absorber 60 is placed on the supporting platform 11 and the electrode 62 passes through the guiding hole 121, the body 61 is in contact with the second side surface 1212 of the guiding hole 121. When the clamping mechanism 20 clamps and fixes the electrode 62, the side surface of the clamping jaw of the clamping mechanism 20 is in contact with the first side surface 1211 of the guiding hole 121, ensuring stable placement of the shock absorber during electrode testing.

[0046] As Figure 5-8 shown, the clamping mechanism 20 includes a first cylinder assembly 21, a first slider 22, and a first clamping jaw 23. A sliding groove 211 is provided in the first cylinder assembly 21. The first slider 22 is located in the sliding groove 211, and the first clamping jaw 23 is fixed to the first slider 22. The two first sliders 22 slide in the sliding groove 211, driving the two first clamping jaws 23 to move towards or away from each other. By adjusting the distance between the two first clamping jaws 23, the fixation and clamping of the shock absorber electrode are achieved.

[0047] During actual installation, the first end face 221 of the first slider 22 is in contact with the sliding groove 211. A first groove 222 is provided on the first slider 22, and a first protrusion 231 is provided at the end of the first clamping jaw 23. The first protrusion 231 is clamped in the first groove 222. Threaded holes are provided on both the first slider 22 and the first clamping jaw 23, and the first clamping jaw 23 and the first slider 22 are fixedly installed through a bolt assembly.

[0048] The first cylinder assembly 21 intakes or exhausts air when the solenoid valve is energized or de-energized, thereby driving the first clamping jaw 23 to clamp or loosen. There is a sensor to detect when the clamping or loosening is in place. To control the speed and tension when the first clamping jaw 23 clamps or loosens, a throttle valve is additionally installed at the air inlet and outlet of the first cylinder assembly 21. The throttle valve can adjust the air pressure of the cylinder's inlet and outlet, and can avoid the problem that when the first clamping jaw 23 clamps or loosens due to the air pressure being too large or unstable, the vibration drives the shock absorber to tilt, resulting in the probe not being able to be inserted in place.

[0049] Refer to Figure 8 , the end of the first clamping jaw 23 is arc-shaped and matches the electrode profile of the shock absorber. A polyurethane gasket is also provided at the end of the first clamping jaw 23, which can prevent damage to the surface of the shock absorber when the first clamping jaw 23 clamps the electrode and plays a good buffering role.

[0050] As Figure 9-11As shown in the figure, the calibration mechanism 30 includes a second cylinder assembly 31, a second slider 32, and a second jaw 33. A chute is provided in the second cylinder assembly 31. The second slider 32 is located in the chute, and the second jaw 33 is fixed to the second slider 32. The two second sliders 32 slide in the chute, driving the two second jaws 33 to move towards or away from each other. By adjusting the distance between the two second jaws 33, fine adjustment and calibration of the position of the shock absorber electrode are achieved.

[0051] During actual installation, the second end face 321 of the second slider 32 is attached to the chute of the second cylinder assembly 31. A second groove 322 is provided on the second slider 32, and a second protrusion 331 is provided at the end of the second jaw 33. The second protrusion 331 is snap-fitted into the second groove 322 to achieve the fixed installation of the second jaw 33 and the second slider 32. When the end 332 of the second jaw 33 calibrates the electrode 62, the end 332 is located on the stepped surface at the end of the electrode 62.

[0052] As Figure 12-14 shown in the figure, the probe testing mechanism 40 includes a pushing cylinder assembly 41, a connecting plate 42, a guide rail 43, a third slider 44, a connecting block 45, and a probe 46. The pushing cylinder assembly 41 is fixed on the testing table 10. The output end of the pushing cylinder assembly 41 is connected with a connecting plate 42. The guide rail 43 is fixed on the connecting plate 42. The third slider 44 is installed on the guide rail 43. The connecting block 45 is installed on the third slider 44. The probe 46 is fixed to the connecting block 45 through a mounting seat.

[0053] During actual operation, the probe may float. Once the probe floats, the probe cannot accurately extend into the electrode, and the probe may get stuck in the electrode. In the present utility model, the probe testing mechanism is arranged to push the probe vertically into the shock absorber electrode, which can avoid the problem of probe damage caused by probe floating.

[0054] It further includes a grasping mechanism 70. The grasping mechanism 70 includes a third cylinder assembly 71 and a third jaw 72. The third jaw 72 is installed on the fourth cylinder assembly 71. During actual operation, the grasping mechanism 70 is fixedly installed on the robot through the front end of the robot. The forward and backward movement of the third cylinder assembly 71 drives the third jaw 72 to move towards or away from each other, realizing the clamping or loosening of the shock absorber, so that the shock absorber can be placed on the testing table.

[0055] Working principle: The automobile shock absorber electrode testing device of the present utility model can place shock absorbers of different models and complete the testing of shock absorber electrodes. Currently, shock absorbers mainly include four models: front left type, front right type, rear left type, and rear right type. First, take Figure 1Taking the front left type shock absorber shown as an example for illustration, the advancing and retreating movement of the third cylinder assembly 71 drives the third jaw 72 to clamp or loosen. The shock absorber is placed on the inspection table. The body 61 of the shock absorber is placed on two support platforms 10. The top of the support platform 10 is provided with a V-shaped or U-shaped groove, which can realize the stable placement of the shock absorber. The electrode 62 of the shock absorber passes through the guiding hole 121 on the guiding seat 12. At this time, the profile of the body 61 of the shock absorber fits well with the second side 1212 of the guiding hole. Then, the first cylinder assembly 21 intakes or exhausts air when the solenoid valve is energized or de-energized, thereby driving the first jaw 23 to clamp or loosen, realizing the fixed clamping of the shock absorber electrode. The size of the air intake and exhaust of the cylinder can also be adjusted by adjusting the throttle valve in the first cylinder assembly 21 to realize the stable clamping of the shock absorber electrode. When the first jaw 23 clamps the electrode, the arc-shaped end of the first jaw 23 matches the profile of the shock absorber electrode, and the side of the first jaw 23 fits with the first side 1211 of the guiding hole 121. Then, the second cylinder assembly 31 intakes or exhausts air when the solenoid valve is energized or de-energized, driving the second jaw 33 to clamp or loosen, realizing the fine adjustment and correction of the position of the shock absorber electrode. When the clamping-in-place sensor sends a signal and lights up and self-locks, the pushing cylinder assembly 41 moves out to make the probe in close contact with the shock absorber electrode. When the detection electrode conduction sensor is triggered, if the detection sensor is triggered and conducts, a qualified detection signal is output. After the solenoid valve of the second cylinder assembly 31 is de-energized and returns to the original position, the pushing cylinder assembly 41 then withdraws from the original position and self-locks and holds. The robot grabs the product and places it on the tray of the current line body, flowing into the next process for assembly, and so on in a cycle.

[0056] If the model of the shock absorber to be detected is changed to the front right type, the body of the shock absorber is still placed on two support platforms. By rotating the shock absorber, the shock absorber electrode passes through the guiding hole, and the test of the shock absorber electrode can also be realized. If the model of the shock absorber to be detected is changed to the rear left type or the rear right type, by reversing the direction of the shock absorber and rotating the shock absorber, the body of the shock absorber is placed on two support platforms, and the electrode passes through the guiding hole, and the test of the shock absorber electrode can also be realized.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
