[0017] Compared with the related art, the fork durability test equipment has the following beneficial effects:

[0018] The fork durability test equipment can stably deliver the fork in the placing groove to the designated work station through the cooperation of the delivery assembly, the quick clamping assembly and the internal components, so that the work staff need only place the fork to be tested in the placing groove instead of placing and fixing the fork to the test work station one by one, thereby greatly improving the feeding efficiency and reducing the manual operation strength. The quick clamping assembly can quickly clamp and release the fork through the synergistic effect of the mounting shaft, the arc-shaped clamping plate, the movable seat, the power-on electromagnet and the first spring, and can ensure uniform and stable clamping force through the real-time monitoring of the pressure sensor, thereby avoiding damage to the fork due to excessive clamping or falling off due to insufficient clamping.

[0019] The adjustable oil injection assembly can freely adjust the oil injection angle of the oil injection pipe through the cooperation of the adjustable oil injection assembly, the oil supply assembly and the internal components, so as to avoid the lack of lubricating oil at the contact position between the fork and the simulation component, and to test the influence of different oil injection angles on the durability of the fork. The oil supply assembly can realize stable delivery of lubricating oil, and can control the oil injection speed and oil amount by adjusting the air supply pressure of the air pump and the gas delivery pipe, so as to ensure uniform and sufficient lubrication of the contact position between the fork and the simulation component and to reduce the wear of the components.

[0020] By coordinating the collection components, filtration components, and internal parts, the slag collection box, drain pipe, and scraper can quickly collect the mixture of iron filings and waste lubricating oil generated during the fork test. When the scraper rotates, it ensures that the mixture in the slag collection box does not accumulate, allowing it to flow quickly into the drain pipe, ensuring no residue is collected and improving collection efficiency. In the filtration component, the inclined plate, electromagnetic chuck, and filter screen can achieve preliminary separation of iron filings and lubricating oil. The electromagnetic chuck can quickly adsorb most of the iron filings, and the filter screen traps fine impurities, improving the separation effect. Secondly, the hydraulic cylinder, pressure plate, and filter cloth can deeply purify the lubricating oil after preliminary filtration, removing residual impurities and ensuring the cleanliness of the recovered lubricating oil. When the lubricating oil in the first tank is insufficient, the recovered clean lubricating oil can be drawn from the second oil cylinder, thereby achieving recycling. Attached Figure Description

[0043] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0044] First embodiment:

[0045] Please refer to the following: Figures 1-8 In the first embodiment of the present invention, the shift fork durability testing equipment includes: a workbench 1, a test chamber 2, a simulation component 10, and a second motor 11. The test chamber 2 is fixedly installed on the top of the workbench 1, the second motor 11 is fixedly installed on the top of the workbench 1, and the simulation component 10 is fixedly installed on the output shaft of the second motor 11. The simulation component 10 adopts the conventional design of the simulation component in the prior art of shift fork durability testing equipment, and mainly includes: a simulation gear, a transmission shaft, and a bearing seat, etc. Both the second motor 11 and the simulation component 10 are located inside the test chamber 2. A fixing frame 7 is fixedly installed on the top of the workbench 1. The simulation component 10 is rotatably connected to the fixed frame 7. A support platform 8 is fixedly installed inside the workbench 1. A collection box 9 is provided at the bottom of the support platform 8. A delivery component is provided at the top of the workbench 1. A movable frame 3 is slidably installed on the top of the workbench 1. Specifically, a transmission mechanism is installed on the top of the workbench 1. The movable frame 3 is slidably installed on the transmission mechanism. The transmission mechanism adopts the conventional design of the transmission mechanism in the prior art. It mainly includes: a motor, a guide rod and a screw, etc. A cylinder 4 is fixedly installed on the top of the movable frame 3. The telescopic end of the cylinder 4 extends to the bottom of the movable frame 3 and is fixedly installed with a quick clamping component.

[0046] The delivery assembly includes a first motor 6, a gear 13, a delivery plate 5, and a rack 14. A support platform is fixedly installed on the top of the worktable 1. The delivery plate 5 is slidably installed on the top of the support platform. The rack 14 is fixedly installed on the bottom of the delivery plate 5. The first motor 6 is fixedly installed on one side of the outer wall of the support platform. The gear 13 is fixedly installed on the output shaft of the first motor 6, and the gear 13 meshes with the rack 14. The top of the delivery plate 5 is provided with a placement groove 12. When the first motor 6 is started, the output shaft of the first motor 6 drives the gear 13 to rotate. Since the gear 13 meshes with the rack 14 at the bottom of the delivery plate 5, the rotation of the gear 13 will drive the delivery plate 5 to slide along the top of the support platform, delivering the shift fork in the placement groove 12 to directly below the moving frame 3. The placement groove 12 provides a placement space for the shift fork and can play a preliminary positioning role for the shift fork, ensuring that the shift fork will not deviate or slip during the delivery process.

[0047] The quick-clamping assembly includes a mounting shaft 16, three arc-shaped clamping plates 166, a movable seat 168, an iron block 167, and an electromagnet 161. The top of the mounting shaft 16 is fixedly mounted on the output shaft of the cylinder 4, and the bottom end of the mounting shaft 16 has a blind groove. The movable seat 168 is slidably mounted in the blind groove, and the outer wall of the movable seat 168 has a first inclined surface. A top post 15 is fixedly mounted on the bottom inner wall of the placement groove 12. The iron block 167 is fixedly mounted on the top of the movable seat 168. The outer wall of the mounting shaft 16 has an annular groove, and the three arc-shaped clamping plates 166 are all set in the annular groove. The three arc-shaped clamping plates 166 are symmetrically distributed at 120 degrees, clamping the shift fork from the circumference. Compared with the traditional two-point or single-point clamping, the clamping force on the shift fork is more uniform, avoiding deformation or damage to the shift fork due to uneven force. One of the arc-shaped clamping plates 166 has a mounting groove on its outer wall, and a pressure rod is fixedly mounted in the mounting groove. Sensor 162, and one end of a connecting plate is fixedly installed on the inner wall of each of the three arc-shaped clamping plates 166. The other end of each of the three connecting plates extends into the blind groove and is fixedly installed with a contact plate 163. The bottom inner wall of the contact plate 163 is provided with a second inclined surface. When the second inclined surface contacts the first inclined surface, the movable seat 168 can easily open the three contact plates 163. The inner wall of each of the three contact plates 163 contacts the outer wall of the movable seat 168. One end of a first spring 164 is fixedly installed on the outer wall of each of the three contact plates 163. The other end of the first spring 164 is fixedly connected to the inner wall of the blind groove. A limit seat is fixedly installed in the blind groove. Electromagnet 161 is slidably installed in the limit seat, and the adsorption end of the electromagnet 161 extends outside the limit seat. One end of a second spring 165 is fixedly installed on the end of the electromagnet 161 away from the adsorption end. The other end of the second spring 165 is fixedly connected to the limit seat.

[0048] In this embodiment:

[0049] Place the fork to be tested in the placement slot 12 of the delivery component, ensuring that the fork faces the position of the simulation component 10 and is placed stably. Then start the first motor 6. The output shaft of the first motor 6 drives the gear 13 to rotate. Since the gear 13 meshes with the rack 14 at the bottom of the delivery plate 5, the rotation of the gear 13 will drive the delivery plate 5 to slide along the top of the support platform, delivering the fork in the placement slot 12 to the bottom of the moving frame 3.

[0050] Then, cylinder 4 is activated, and its telescopic end drives the mounting shaft 16 downward until the three arc-shaped clamps 166 are inserted into the tail connection hole of the shift fork. At this time, the top column 15 at the bottom of the placement groove 12 pushes the movable seat 168 to slide upward along the blind groove of the mounting shaft 16. The movable seat 168 presses the three contact plates 163, causing the three arc-shaped clamps 166 to open outward and fit against the inner wall of the tail connection hole of the shift fork. At this time, the pressure sensor 162 contacts the inner wall of the tail connection hole of the shift fork, cylinder 4 stops driving the mounting shaft 16 downward, and at the same time, the electromagnetic switch is activated. When the iron block 167 is energized, the electromagnet 161 attracts the iron block 167, fixing the position of the movable seat 168. This allows the three arc-shaped clamps 166 to clamp the shift fork. After clamping, the cylinder 4 drives the shift fork to return to its original position. The transmission mechanism at the top of the workbench 1 is then activated, and the moving frame 3 slides along the top of the workbench 1 to the corresponding position in the test chamber 2. The cylinder 4 then fine-tunes the height of the shift fork to align it with the simulation component 10. Finally, the second motor 11 is activated, causing the simulation component 10 to rotate, thus beginning the durability test on the shift fork.

[0051] Second embodiment:

[0052] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0053] Please refer to the following: Figures 9-14 In the fork durability testing device provided in this embodiment, a lubrication mechanism is provided on the top inner wall of the movable frame 3.

A guide frame is provided on the top inner wall of the movable frame 3. One end of the bidirectional lead screw 20 is rotatably mounted inside the guide frame. The third motor 19 is fixedly mounted on one side outer wall of the guide frame, and its output shaft extends into the guide frame and is fixedly connected to the other end of the bidirectional lead screw 20. Both hinge seats 28 are threaded to the outside of the bidirectional lead screw 20, and both hinge seats 28 are slidably connected to the guide frame. Both rotating seats 21 are rotatably mounted on the top inner wall of the movable frame 3. The two fuel injection pipes 30 are respectively fixedly mounted on the two... At the bottom of each rotating seat 21, one end of a telescopic rod 29 is fixedly installed on the outer wall of each rotating seat 21 near the guide frame. The other ends of the two telescopic rods 29 are rotatably connected to two hinge seats 28 respectively. The telescopic rod 29 consists of a solid rod and a hollow limiting rod. The solid rod is slidably installed in the hollow limiting rod, and one end of the solid rod rotates on the hinge seat 28. Furthermore, since the two threads on the bidirectional lead screw 20 are arranged oppositely, when the third motor 19 is started, its output shaft drives the bidirectional lead screw 20 to rotate. The two hinge seats 28 slide in opposite or the same direction along the guide frame, and the rotating seats 21 are pulled to rotate by the telescopic rods 29, thereby adjusting the injection angle of the two injection pipes 30.

[0055] The oil supply assembly includes a first housing 17, an oil pump 26, a first oil cylinder 22, and an air pump 18. The first housing 17 is fixedly installed on one outer wall of the movable frame 3. The oil pump 26 is fixedly installed on the top of the first housing 17. A double-headed valve 25 is fixedly installed at the water inlet end of the oil pump 26. A second oil suction pipe 49 is provided inside the first housing 17. One end of the second oil suction pipe 49 extends to the outside of the first housing 17 and is fixedly connected to one end of the double-headed valve 25. The first oil cylinder 22 is fixedly installed on the top inner wall of the movable frame 3. A first one-way valve is fixedly installed on the outer wall of the first oil cylinder 22. One end of an oil delivery pipe 27 is fixedly installed at the water outlet end of the oil pump 26. The other end of the oil delivery pipe 27 is fixedly connected to the first one-way valve on the outer wall of the first oil cylinder 22. The first oil cylinder 22 is fixedly connected to a third check valve at its bottom. One end of each of the two oil supply pipes 24 is fixedly connected to the third check valve, and the other end of each of the two oil supply pipes 24 is fixedly connected to the two oil injection pipes 30 respectively. The air pump 18 is fixedly installed on the top of the movable frame 3. One end of the air supply pipe 23 is fixedly installed at the exhaust end of the air pump 18. The top of the first oil cylinder 22 is fixedly installed with a second check valve. The air pump 18 can adjust the air supply pressure according to the lubrication requirements to control the oil injection speed and oil quantity. The other end of the air supply pipe 23 is fixedly connected to the second check valve at the top of the first oil cylinder 22. The unidirectional conduction characteristics of the first check valve, the second check valve, and the third check valve can accurately control the flow direction and flow rate of the lubricating oil and prevent backflow or leakage of oil.

[0056] In this embodiment:

[0057] The third motor 19 is started, and its output shaft drives the bidirectional lead screw 20 to rotate. The two hinge seats 28 slide in opposite or the same direction along the guide frame. The telescopic rod 29 pulls the rotating seat 21 to rotate, thereby adjusting the oil injection angle of the two oil injection pipes 30. After the angle is adjusted, the oil pump 26 is started and one end of the double-headed valve 25 is opened. The oil pump 26 draws lubricating oil from the first housing 17 through the second oil pipe 49 and delivers it to the first oil cylinder 22 through the oil delivery pipe 27. Then the air pump 18 is started. The air pump 18 injects gas into the first oil cylinder 22 through the air delivery pipe 23 to increase the pressure inside the cylinder, so that the lubricating oil is quickly delivered to the two oil injection pipes 30 through the two oil supply pipes 24. The oil injection pipes 30 spray lubricating oil onto the contact part between the docked shift fork and the simulated component 10. The oil supply continues during the shift fork durability test.

The electromagnetic chuck 40 is fixedly installed in the first opening. The inclined plate also has a second opening, and the filter screen 39 is fixedly installed in the second opening. When the electromagnetic chuck 40 is activated, the mixture enters the separation box 33 and flows along the inclined plate. The electromagnetic chuck 40 adsorbs most of the iron filings in the mixture, and the remaining mixture is filtered through the filter screen 39 to further trap fine iron filings, thus performing preliminary filtration. The filter press 42 is fixedly installed at the bottom of the support platform 8. One end of a guide pipe 41 is fixedly installed at the bottom of the second opening, and the other end of the guide pipe 41 is fixed to the filter press 42. The separation box 33 is connected to a third opening. One end of the slag discharge pipe 43 is fixedly installed at the bottom of the third opening. The other end of the slag discharge pipe 43 extends to the top of the collection box 9. A hydraulic cylinder 44 is fixedly installed on one side of the outer wall of the filter press box 42. The telescopic end of the hydraulic cylinder 44 extends into the filter press box 42 and is fixedly installed with a pressure plate. A filter plate 48 is fixedly installed inside the filter press box 42. A filter cloth 47 is fixedly installed on the side of the filter plate 48 near the pressure plate. The second oil cylinder 32 is fixedly installed at the bottom of the support platform 8. One end of the oil discharge pipe 46 is fixedly installed at the bottom of the filter press box 42. The other end of the oil discharge pipe 46 is fixedly connected to the second oil cylinder 32. The second oil cylinder 32 is provided with a first oil suction pipe 31. One end of the first oil suction pipe 31 extends to the outside of the second oil cylinder 32 and is fixedly connected to the other end of the double-headed valve 25.

[0063] The filter press 42 has an inspection port on the side near the collection box 9. A maintenance door 45 for sealing the inspection port is also installed on one side of the filter press 42. After the test, the maintenance door 45 of the filter press 42 can be opened and the residual impurities on the filter cloth 47 and filter plate 48 can be cleaned through the inspection port to ensure the normal operation of the filter assembly in the future.

[0064] In this embodiment:

[0065] During the fork test, the iron filings generated will mix with the lubricating oil to form a mixture. At this time, the mixture will flow into the slag collection box 35 through the drain port 34 of the fixed frame 7. The second motor 11 is started, and the output shaft of the second motor 11 drives the fixed ring plate 38 to rotate synchronously. The two scrapers 37 on the fixed ring plate 38 rotate in the slag collection box 35, scraping the mixture into the two drain pipes 36. The mixture is transported to the separation box 33 through the drain pipes 36. Then, the electromagnetic chuck 40 is started. After the mixture enters the separation box 33, it flows along the inclined plate. The electromagnetic chuck 40 adsorbs most of the iron filings in the mixture. The remaining mixture is filtered through the filter screen 39 to further trap the fine iron filings. The lubricating oil after preliminary filtration flows into the filter press box 42 through the guide pipe 41. The iron filings adsorbed on the electromagnetic chuck 40 are periodically turned off by closing the electromagnetic chuck 40, so that they fall into the collection box 9 along the slag discharge pipe 43.

[0066] Then, the hydraulic cylinder 44 is activated. The telescopic end of the hydraulic cylinder 44 drives the pressure plate to move towards the filter plate 48, squeezing the lubricating oil in the filter box 42. The oil is then filtered through the filter cloth 47 to remove residual impurities. The filtered clean lubricating oil flows into the second oil cylinder 32 for storage through the oil drain pipe 46. When the lubricating oil in the first box 17 is insufficient, the double-headed valve 25 is closed at one end connected to the second oil extraction pipe 49, and the end connected to the first oil extraction pipe 31 is opened. The recovered clean lubricating oil is then extracted from the second oil cylinder 32 through the first oil extraction pipe 31 to achieve recycling.

[0067] After the test, open the maintenance door 45 of the filter press 42 and clean the residual impurities on the filter cloth 47 and filter plate 48 through the inspection port to ensure the normal operation of the filter assembly.
