Description

Technical Field

[0001] This invention relates to the field of steering knuckle technology, and in particular to a steering knuckle testing mechanism and testing method. Background Technology

[0002] The steering knuckle is a key component in a car's steering system, connecting the wheels to the suspension system and serving to support the wheels and transmit steering forces. Its design and performance directly affect the vehicle's handling, safety, and comfort. The steering knuckle is typically connected to the front axle of the car using a pin, and also requires a thrust bearing. If the steering knuckle's machining precision is insufficient, it can easily cause problems such as pin hole cracking, thrust bearing damage, and abnormal noise. Therefore, it is necessary to inspect the steering knuckle during machining. Utility model CN210108723U discloses a steering knuckle testing device, including a connecting base plate, a fixed seat fixedly installed at the center of the top of the connecting base plate, a fixed threaded rod fixedly installed at the center of the top of the fixed seat, a fixed frame fixedly installed at the top of the connecting base plate, a hydraulic cylinder fixedly installed at the center of the top of the fixed frame, a detection motor fixedly installed through the hydraulic rod of the hydraulic cylinder passing through the plate wall at the center of the top of the fixed frame, and a detection plate corresponding to the fixed threaded rod fixedly installed on the drive shaft of the detection motor. This steering knuckle testing device, through the fixedly installed detection motor, facilitates the rotation of the detection plate to test the steering knuckle, avoiding the low efficiency and high labor intensity of manual testing, and improving the testing efficiency of the staff; the fixedly installed hydraulic cylinder facilitates the movement of the detection motor and the detection plate; and the fixed detection plate, the first fixed hole, the detection fixing rod, and the fixed threaded rod facilitate the fixing of the center of the steering knuckle.

[0003] In existing technologies, when inspecting steering knuckles in actual use, the dimensions of the inspection mechanism are usually fixed, while the dimensions of different steering knuckle models are not consistent. This leads to inconvenience in inspecting steering knuckles. Therefore, we propose a steering knuckle inspection mechanism and inspection method to solve the above-mentioned problems. Summary of the Invention

[0004] Based on the technical problems existing in the background art, the present invention proposes a steering knuckle detection mechanism and detection method.

[0005] This invention proposes a steering knuckle detection mechanism, comprising a base, a support frame fixedly connected to the top of the base, a lifting rod slidably connected to the inner wall of the support frame and passing through the support frame, a motor fixedly connected to the bottom of the lifting rod, a connecting sleeve fixedly connected to the bottom of the motor output shaft, a positioning mechanism on the top of the support frame, two clamping plates symmetrically slidably connected to the top of the base, each clamping plate having a limiting mechanism on its opposite side, a pressure block slidably connected to its opposite side, a threaded rod rotatably connected to the top of each pressure block, and a threaded sleeve on its opposite side, the inner wall of the threaded sleeve being threadedly connected to the outer wall of the threaded rod.

[0006] Preferably, the limiting mechanism includes: two support plates, two unlocking plates, two fixing rods, two pressure plates, two push rods, two connecting rods, two insertion rods, and two insertion plates; Two support plates are fixedly connected to the two clamping plates on opposite sides. Two unlocking plates are slidably connected to the two clamping plates on opposite sides. Two fixing rods are fixedly connected to the bottom of the corresponding support plates, and the fixing rods pass through the unlocking plates. Two connecting rods are slidably connected to the bottom of the corresponding unlocking plates. Two push rods are rotatably connected to the front of the corresponding connecting rods. Two pressure plates are rotatably connected to the rear of the corresponding push rods. Two insert rods are fixedly connected to the two connecting rods on opposite sides. Two insert plates are slidably connected to the two clamping plates on opposite sides. The tops of the two insert plates are fixedly connected to the bottoms of the unlocking plates. The top of the base has two symmetrical slots, which are compatible with the insert plates. Limiting grooves are provided on the opposite sides of the two fixing rods, and the limiting grooves are compatible with the insert rods.

[0007] Furthermore, by pushing the pressure plate upward, the pressure plate will push the push rod, and the push rod will move to the right, and the connecting rod will move laterally, thereby causing the insert rod to disengage from the limiting groove and thus unlocking the unlocking plate. At this time, the unlocking plate can be pushed upward to compress the positioning spring and drive the insert plate upward. The upward movement of the insert plate will disengage from the slot and thus unlock the clamping plate.

[0008] Preferably, the positioning mechanism includes: a control plate, a sliding frame, a sliding shaft, a sliding rod, a connecting block, and a positioning plate; The connecting block is slidably connected to the top of the support frame, the positioning plate is fixedly connected to the left side of the connecting block, the slide rod is fixedly connected to the right side of the connecting block, the slide shaft is fixedly connected to the front side of the slide rod, the slide frame is slidably connected to the outer wall of the slide shaft, the control plate is fixedly connected to the top of the slide frame, and a positioning groove is provided on the right side of the lifting rod, which engages with the positioning plate.

[0009] Furthermore, by pressing down on the control panel, the pressure plate moves, causing the sliding frame to move down. When the sliding frame moves, it pushes the sliding shaft to move. When the sliding shaft moves, it causes the sliding rod to move to the right. At this time, the sliding rod moves, causing the connecting block to move to the right. When the connecting block moves, it compresses the return spring. At the same time, the moving connecting block moves, causing the positioning plate to move. At this time, the moving positioning plate will disengage from the positioning groove, thereby unlocking the lifting rod.

[0010] Preferably, a positioning spring is fixedly connected to the bottom of the support plate, and the bottom of the positioning spring is fixedly connected to the top of the unlocking plate.

[0011] Furthermore, the spring force of the positioning spring facilitates the horizontal movement and reset of the unlocking plate.

[0012] Preferably, two springs are fixedly connected to the bottom of each of the two unlocking plates, and the bottom of each spring is fixedly connected to the top of the corresponding pressure plate.

[0013] Furthermore, the spring force facilitates the reset of the pressure plate, thereby resetting the insertion rod and engaging it with the limit groove to fix the unlocking plate in place.

[0014] Preferably, each of the two unlocking plates has a fixedly connected upright plate at its bottom, and the upright plate has a hollow structure. The side portions of the two upright plates that are far apart from each other are movably connected to the side portions of the two pressure plates that are far apart from each other. The inner walls of the two upright plates are movably connected to the outer walls of the corresponding connecting rods.

[0015] Furthermore, the upright plate facilitates the limiting of the pressure plate, enabling it to move stably vertically. The inner wall of the upright plate, in conjunction with the connecting rod, restricts the connecting rod, allowing it to move stably laterally.

[0016] Preferably, a hollow plate is fixedly connected to the top of the support frame, and the right side of the hollow plate is movably connected to the left side of the control panel.

[0017] Furthermore, the hollow plate facilitates the support of the control board, enabling it to move stably up and down.

[0018] Preferably, the inner wall of the hollow plate is movably connected to the outer wall of the slide rod, and a return spring is fixedly connected to the left side of the hollow plate. The left side of the return spring is fixedly connected to the right side of the connecting block.

[0019] Furthermore, the spring force of the reset spring facilitates the reset of the positioning plate and the control plate.

[0020] This invention also proposes a testing method for a steering knuckle testing mechanism, comprising the following steps: S1: First, install the appropriately sized connecting sleeve at the bottom of the motor output shaft; S2: Place the steering knuckle to be tested on the top of the base and position the steering knuckle between the two clamping plates. At this time, first push the pressure plate to unlock the unlocking plate, then push the unlocking plate to move so that the insert plate is disengaged from the slot to unlock the clamping plate. By pushing the clamping plate to move laterally, the steering knuckle is clamped and fixed. Then rotate the threaded rod to move the pressure block down to press and fix the steering knuckle. S3: By pushing the control panel down, the positioning plate moves laterally to unlock the lifting rod. At this time, pushing the lifting rod down will drive the motor down. The movement of the motor will drive the connecting sleeve down and engage with the top outer wall of the steering knuckle. At this time, the motor can be started to test the steering knuckle.

[0021] The beneficial effects of this invention are: 1. The lifting rod is supported and limited by the support frame. The lifting rod facilitates the movement of the motor and connecting sleeve for inspection of the steering knuckle. The clamping plate facilitates the clamping and fixing of the steering knuckle. The rotation of the threaded rod facilitates the movement of the pressure block to press and fix the steering knuckle. 2. By pushing the pressure plate upward, the pressure plate will push the push rod. The push rod will move the connecting rod to the right. The connecting rod will move the insert rod laterally, thereby disengaging the insert rod from the limiting groove and unlocking the unlocking plate. At this time, the unlocking plate can be pushed upward to compress the positioning spring and move the insert plate upward. The upward movement of the insert plate will disengage from the slot, thereby unlocking the clamping plate. 3. By pressing down on the control panel, the pressure plate moves and the slide frame moves down. When the slide frame moves, it pushes the slide shaft to move. When the slide shaft moves, it moves the slide rod to the right. When the slide rod moves, it moves the connecting block to the right. When the connecting block moves, it compresses the return spring. At the same time, the moving connecting block moves the positioning plate. When the positioning plate moves, it disengages from the positioning groove, thus unlocking the lifting rod. This invention uses a simple structure to fix or unlock the clamping plate and the lifting rod, thus facilitating the fixing of different models of steering knuckles according to usage requirements, so as to enable the testing of steering knuckles. The operation is simple and convenient, and it has good practicality. Attached Figure Description

[0024] The present invention will be further explained below with reference to specific embodiments. Example

[0025] refer to Figure 1-5 This embodiment proposes a steering knuckle detection mechanism, including a base 1, a support frame 2 fixedly connected to the top of the base 1, a lifting rod 17 slidably connected to the inner wall of the support frame 2, and the lifting rod 17 passing through the support frame 2, a motor 18 fixedly connected to the bottom of the lifting rod 17, a connecting sleeve 19 fixedly connected to the bottom of the output shaft of the motor 18, a positioning mechanism provided at the top of the support frame 2, two clamping plates 3 symmetrically slidably connected to the top of the base 1, and a limiting mechanism provided on the side of the two clamping plates 3 that are far apart from each other, a pressure block 5 slidably connected to the side of the two clamping plates 3 that are close to each other, a threaded rod 4 rotatably connected to the top of the two pressure blocks 5, and a threaded sleeve provided on the side of the two clamping plates 3 that are close to each other, with the inner wall of the threaded sleeve threadedly connected to the outer wall of the threaded rod 4.

[0026] The above-mentioned mechanism supports and limits the lifting rod 17 through the support frame 2, facilitates the movement of the motor 18 and the connecting sleeve 19 through the lifting rod 17 to inspect the steering knuckle, facilitates the clamping and fixing of the steering knuckle through the clamping plate 3, and facilitates the movement of the pressure block 5 through the rotation of the threaded rod 4 to press and fix the steering knuckle.

[0027] In this embodiment, the limiting mechanism includes: two support plates 6, two unlocking plates 7, two fixing rods 8, two pressure plates 10, two push rods 13, two connecting rods 14, two insertion rods 15 and two insertion plates 16. Two support plates 6 are fixedly connected to the two clamping plates 3 on opposite sides. Two unlocking plates 7 are slidably connected to the two clamping plates 3 on opposite sides. Two fixing rods 8 are fixedly connected to the bottom of the corresponding support plates 6, and the fixing rods 8 pass through the unlocking plates 7. Two connecting rods 14 are slidably connected to the bottom of the corresponding unlocking plates 7. Two push rods 13 are rotatably connected to the front of the corresponding connecting rods 14. Two pressure plates 10 are rotatably connected to the rear of the corresponding push rods 13. Two insert rods 15 are fixedly connected to the two connecting rods 14 on opposite sides. Two insert plates 16 are slidably connected to the two clamping plates 3 on opposite sides. The tops of the two insert plates 16 are connected to the unlocking plates 7. The bottom of plate 7 is fixedly connected, and the top of base 1 is symmetrically provided with two slots. The slots are adapted to insert plate 16. Limiting grooves are provided on the side of the two fixed rods 8 that are close to each other. The limiting grooves are adapted to insert rod 15. By pushing the pressure plate 10 to move upward, the pressure plate 10 will push the push rod 13. The push rod 13 will move to the right, and the connecting rod 14 will move laterally, thereby causing the insert rod 15 to disengage from the limiting groove and thus unlocking plate 7. At this time, the unlocking plate 7 can be pushed upward to compress the positioning spring 9 and drive the insert plate 16 to move upward. The upward movement of the insert plate 16 will disengage from the slot and thus unlock clamp 3.

[0028] In this embodiment, the positioning mechanism includes: a control plate 20, a sliding frame 22, a sliding shaft 23, a sliding rod 24, a connecting block 25, and a positioning plate 27; The connecting block 25 is slidably connected to the top of the support frame 2. The positioning plate 27 is fixedly connected to the left side of the connecting block 25. The slide rod 24 is fixedly connected to the right side of the connecting block 25. The slide shaft 23 is fixedly connected to the front side of the slide rod 24. The slide frame 22 is slidably connected to the outer wall of the slide shaft 23. The control plate 20 is fixedly connected to the top of the slide frame 22. A positioning groove is provided on the right side of the lifting rod 17. The positioning groove engages with the positioning plate 27. By pressing down the control plate 20, the pressure plate 10 moves and drives the slide frame 22 to move down. When the slide frame 22 moves, it pushes the slide shaft 23 to move. When the slide shaft 23 moves, it drives the slide rod 24 to move to the right. At this time, the movement of the slide rod 24 drives the connecting block 25 to move to the right. When the connecting block 25 moves, it compresses the return spring 26. At the same time, the movement of the connecting block 25 drives the positioning plate 27 to move. At this time, the movement of the positioning plate 27 will disengage from the positioning groove, thereby unlocking the lifting rod 17.

[0029] In this embodiment, a positioning spring 9 is fixedly connected to the bottom of the support plate 6. The bottom of the positioning spring 9 is fixedly connected to the top of the unlocking plate 7. The elastic force of the positioning spring 9 facilitates the horizontal movement and reset of the unlocking plate 7.

[0030] In this embodiment, the bottom of each of the two unlocking plates 7 is fixedly connected with a storage spring 11. There are two storage springs 11. The bottom of the two storage springs 11 is fixedly connected to the top of the corresponding pressure plate 10. Through the elastic force of the storage spring 11, the pressure plate 10 is easily pushed to reset, thereby driving the insertion rod 15 to reset and engage with the limiting groove to fix the unlocking plate 7.

[0031] In this embodiment, the bottom of each of the two unlocking plates 7 is fixedly connected to a vertical plate 12, and the vertical plate 12 is a hollow structure. The side of the two vertical plates 12 that is far apart from each other is movably connected to the side of the two pressure plates 10 that is far apart from each other. The inner wall of the two vertical plates 12 is movably connected to the outer wall of the corresponding connecting rod 14. The vertical plate 12 can conveniently limit the pressure plate 10, so that the pressure plate 10 can move vertically and stably. The inner wall of the vertical plate 12 and the connecting rod 14 cooperate to restrict the connecting rod 14, so that the connecting rod 14 can move horizontally and stably.

[0032] In this embodiment, a hollow plate 21 is fixedly connected to the top of the support frame 2. The right side of the hollow plate 21 is movably connected to the left side of the control plate 20. The hollow plate 21 facilitates the support of the control plate 20 so that the control plate 20 can move up and down stably.

[0033] In this embodiment, the inner wall of the hollow plate 21 is movably connected to the outer wall of the slide bar 24. A return spring 26 is fixedly connected to the left side of the hollow plate 21. The left side of the return spring 26 is fixedly connected to the right side of the connecting block 25. The elastic force of the return spring 26 facilitates the reset of the positioning plate 27 and the control plate 20.

[0034] This invention also proposes a testing method for a steering knuckle testing mechanism, comprising the following steps: S1: First, install the appropriately sized connecting sleeve 19 at the bottom of the output shaft of the motor 18; S2: Place the steering knuckle to be tested on the top of the base 1 and position the steering knuckle between the two clamping plates 3. At this time, first push the pressure plate 10 to unlock the unlocking plate 7, then push the unlocking plate 7 to move so that the insert plate 16 is disengaged from the slot to unlock the clamping plate 3. By pushing the clamping plate 3 to move laterally, the steering knuckle is clamped and fixed. Then rotate the threaded rod 4 to drive the pressure block 5 to move down and press and fix the steering knuckle. S3: By pushing the control plate 20 down, the positioning plate 27 is moved laterally to unlock the lifting rod 17. At this time, pushing the lifting rod 17 down will drive the motor 18 down. The movement of the motor 18 will drive the connecting sleeve 19 down to engage with the top outer wall of the steering knuckle. At this time, the motor 18 can be started to test the steering knuckle.

[0035] Working principle: In actual use, firstly, according to the size of the steering knuckle, corresponding slots, limiting slots, and positioning slots are made on the top of the base 1, the side of the fixed rod 8, and the side of the lifting rod 17. Then, the steering knuckle to be tested is placed on the top of the base 1, with the top of the steering knuckle aligned with the connecting sleeve 19, and the steering knuckle positioned on the side where the two clamping plates 3 are close to each other. Next, the pressure plate 10 is pushed upwards. The movement of the pressure plate 10 compresses the storage spring 11, and the movement of the pressure plate 10 pushes the push rod 13. The movement of the push rod 13 causes the connecting rod 14 to move to the right, and the movement of the connecting rod 14 causes the insertion rod 15 to move laterally, thereby disengaging the insertion rod 15 from the limiting slot and unlocking the unlocking plate 7. When the position spring 9 is compressed, the unlocking plate 7 can be pushed upwards, causing the insertion plate 16 to move upwards. The upward movement of the insertion plate 16 disengages from the slot, thus unlocking the clamping plate 3. Pushing the clamping plate 3 laterally allows the steering knuckle to be clamped and fixed. Once the clamping plate 3 is fixed to the steering knuckle, releasing the unlocking plate 7 causes the position spring 9 to push the unlocking plate 7 downwards, causing the insertion plate 16 to move downwards and reset, fixing the clamping plate 3. Then, releasing the pressure plate 10 causes the storage spring 11 to push the pressure plate 10 downwards and reset. The reset of the pressure plate 10 pulls the push rod 13 to reset, which in turn causes the connecting rod 14 to reset, allowing the insertion rod 15 to engage with the limiting groove and fix the unlocking plate 7. Moving the unlocking plate 7 will then move the insertion plate 16 upwards. 6. The downward movement engages with the slot to fix the clamping plate 3, thereby clamping and fixing the steering knuckle. At this time, rotating the threaded rod 4 causes the pressure block 5 to move downward, pressing and fixing the steering knuckle, thus stabilizing it. Then, pressing down on the control plate 20 causes the pressure plate 10 to move, which in turn moves the sliding frame 22 downward. The movement of the sliding frame 22 pushes the sliding shaft 23 to move, which in turn moves the sliding rod 24 to the right. The movement of the sliding rod 24 then moves the connecting block 25 to the right, which in turn compresses the return spring 26. Simultaneously, the movement of the connecting block 25 moves the positioning plate 27, which then disengages from the positioning slot, thus unlocking the lifting rod 17. At this point, pushing the lifting rod 17... The movement of the motor 18 causes it to move downwards, which in turn causes the connecting sleeve 19 to move downwards. The connecting sleeve 19 then engages with the top outer wall of the steering knuckle. At this point, the control plate 20 is released, and the return spring 26 pushes the connecting block 25 to move laterally to reset, which in turn moves the positioning plate 27 and the slide rod 24. The positioning plate 27 engages with the positioning groove to fix the lifting rod 17, thus fixing the connecting sleeve 19. Simultaneously, the movement of the slide rod 24 causes the slide shaft 23 to move, which in turn resets the slide frame 22, thereby resetting the control plate 20. At this point, the motor 18 is started, and the rotation of the output shaft of the motor 18 causes the connecting sleeve 19 to rotate, thereby rotating the steering knuckle and achieving the effect of detecting the steering knuckle.

[0036] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
