Description

Technical Field

[0001] This utility model relates to the field of precision machining technology for automotive parts, and more specifically, to a precision grinding device for automotive parts. Background Technology

[0002] In the automotive manufacturing industry, the precision grinding process for parts faces multiple technical challenges. Existing grinding equipment has many shortcomings in practical applications, which seriously affect production efficiency and processing quality.

[0003] Firstly, in terms of the production process, existing equipment generally suffers from low automation. Most equipment still relies on manual labor for loading and unloading workpieces. This not only increases the labor intensity of workers but also leads to frequent interruptions in the production process. Operators need to perform physical labor repeatedly, which is not only inefficient but also prone to fatigue, affecting the quality of work.

[0004] Secondly, there are serious technical limitations in workpiece clamping. Automotive parts typically have complex geometries and irregular surface features, which places high demands on the clamping system. However, the pneumatically driven clamping block method commonly used in existing technologies is too simple and can only achieve single-point clamping. This single-point clamping method has obvious defects: due to the uneven distribution of clamping points, local stress concentration is prone to occur in the workpiece during processing, which not only affects the grinding accuracy but may also lead to workpiece deformation or damage. More importantly, the clamping system design of most equipment lacks flexibility and can only adapt to parts of specific specifications and shapes. When different models or specifications of parts need to be processed, the equipment cannot make effective adaptive adjustments. This limitation seriously restricts the application range of the equipment and reduces the flexibility of the production line.

[0005] Furthermore, while some improved equipment attempts to achieve stable clamping of parts of different shapes and specifications by adding adjustable mechanisms, these improved designs still have serious reliability issues. The structural design of these devices is too simple and lacks overall rigidity, often leading to problems during actual use. In particular, during high-speed grinding, continuous vibration and impact can easily cause the adjusted clamping structure to loosen. This instability directly affects the processing quality: a loose clamping structure may cause the workpiece to shift position, affecting processing accuracy; unstable clamping force may cause scratches or deformation on the workpiece surface, leading to product scrap. These problems not only reduce product quality but also increase production costs and rework rates, seriously affecting the company's production efficiency. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a precision grinding device for automotive parts, which has the following advantages:

[0019] 1. By setting a grinding device on the base, including a combination structure of lifting components, grinding assembly and mechanical claw assembly, the mechanical claw assembly is moved by the cooperation of longitudinal and transverse components. The parts to be processed are transported to the designated position by the conveyor, and then clamped and placed on the placement table by the mechanical claw assembly. Then, the grinding assembly performs precision grinding. After the processing is completed, the mechanical claw assembly transfers it to the other side of the conveyor for the next process. This realizes the automated loading and unloading and continuous operation of parts grinding processing, and effectively solves the problem of low production efficiency caused by the reliance on manual loading and unloading of traditional equipment.

[0020] 2. By setting up a clamping device, including the precise matching of components such as the control sleeve, connecting sleeve, clamping frame, fixing frame, adapting plate, adapting spring, adapting sleeve, adapting rod, inner sleeve, locking block, adjusting block and adjusting groove, the clamping frame is moved by the piston rod driven by the double-headed cylinder, so that the adapting rod contacts the surface of the part. The elastic action of the adapting spring and the adapting rod realize multi-point clamping. At the same time, with the help of the locking mechanism of the locking block and the adapting rod, as well as the inclined structure design of the adjusting block and the adjusting groove, multi-point adaptive clamping of irregularly shaped parts is realized. This not only solves the problem of uneven force in traditional single-point clamping, but also realizes flexible clamping of parts of different specifications.

[0021] 3. By setting up a locking mechanism, including a linkage structure of components such as a return plate, adapter plate, adapter rod, locking sleeve, adapter hole, return block, connecting block, adapter groove, and return spring, after clamping is completed, the rotation of the return plate drives the adapter hole and adapter groove to move. Utilizing the precise fit between the adapter rod and the adapter plate, as well as the elasticity of the return spring, the locking sleeve is limited by the limiting block and limiting groove, as well as the adapter rod and the adapter plate. At the same time, the locking sleeve limits the locking rod. Combined with the locking action of the locking rod and the locking groove, reliable fixation of the adjusted position is achieved. This completely solves the problem of structural loosening and unstable clamping that is prone to occur in traditional devices during high-speed grinding, and significantly improves the stability and reliability of the device.

Adapter groove 21 is opened on adapter plate 15. Both ends of return spring 22 are connected to return block 19 and connecting block 20 respectively. Return block 19 is fixedly connected to one side of return plate 14, and connecting block 20 is fixedly connected to the outside of connecting sleeve 3.

[0033] A hydraulic cylinder 23 is detachably mounted on the base 1. A hydraulic rod 24 is connected to the output end of the hydraulic cylinder 23. A placement platform 25 is detachably mounted on the top of the hydraulic rod 24.

[0034] A double-headed cylinder 26 is provided on one side of the placement platform 25. The double-headed cylinder 26 has piston rods 27 at both ends, and the other end of the piston rods 27 is connected to the clamping frame 4.

[0035] A linkage block 28 is connected to the other side of the locking block 11, and a linkage groove 29 is opened at one end of the inner sleeve 10. The linkage block 28 is slidably disposed in the linkage groove 29.

[0036] Multiple locking rods 30 are slidably provided on the side wall of the control sleeve 2. A cooperating spring 31 is provided on the outer side of the control sleeve 2. Multiple locking grooves 32 are opened on the outer wall of the connecting sleeve 3. One end of the locking rod 30 is connected to the outer wall of the control sleeve 2 through the cooperating spring 31, and the other end of the locking rod 30 is inserted into the locking groove 32. An adapter spring 33 is movably sleeved on the outer side of the adapter rod 16. The adapter spring 33 is connected to one side of the lock sleeve 17, and the other end of the adapter spring 33 is in contact with the return plate 14.

[0037] A limiting groove 34 is provided on the outer side of the connecting sleeve 3, and a limiting block 35 is fixedly provided on the inner side of the locking sleeve 17. The limiting block 35 is slidably disposed in the limiting groove 34.

[0038] In this embodiment, when it is necessary to clamp the parts, the parts to be ground are first placed on the placement table 25. Then, the hydraulic cylinder 23 is opened, so that the hydraulic cylinder 23 drives the placement table 25 to rise and fall through the hydraulic rod 24 connected to the output end, thereby adjusting the placement height of the parts. After the adjustment is appropriate, the hydraulic cylinder 23 is closed. Then, the return plate 14 is rotated, so that the return plate 14 drives the adapter hole 18 and the adapter groove 21 to rotate. At the same time, the return plate 14 drives the return block 19 to rotate. Then, the return block 19 cooperates with the connecting block 20 to compress the return spring 22. When the return spring 22 is compressed to the limit, the adapter hole 18 just rotates to the position concentric with the adapter plate 15. At this time, the locking sleeve 17 is pushed, and the locking sleeve 17 drives the limiting block 35 along the limiting groove. As the locking rod 34 slides, it causes the adapter rod 16 and adapter plate 15 to gradually slide into the adapter hole 18. The locking sleeve 17 and the return plate 14 cooperate to compress the adapter spring 33. When the adapter spring 33 is compressed to its limit, the adapter plate 15 near the locking sleeve 17 passes through the adapter hole 18 and reaches the other side of the return plate 14. At this point, the return plate 14 is released, and the return spring 22 pushes the return block 19 to rotate the return plate 14 in the opposite direction. Then, the return plate 14 causes the adapter hole 18 and the adapter groove 21 to rotate in the opposite direction. The adapter rod 16 then enters the adapter groove 21. The adapter rod 16 and the adapter plate 15 near the locking sleeve 17 cooperate to limit the locking sleeve 17 to the side of the return plate 14. Then, the locking sleeve 17 no longer limits the locking rod 30, and then... The control sleeve 2 moves multiple locking rods 30 that slide on its side wall. The inner wall of the locking groove 32 on the outer side of the connecting sleeve 3 then presses against the inner end of the locking rod 30. Due to the rounded corners at the edges of the locking groove 32 and the rounded corners at the ends of the locking rods 30, the inner end of the locking rod 30 slides out of the locking groove 32. The outer end of the locking rod 30 then stretches the cooperating spring 31. Simultaneously, the inner wall of the control sleeve 2 is connected to the outer wall of the inner sleeve 10 via threads, and the cooperation of the linkage block 28 and the linkage groove 29 limits the inner sleeve 10, preventing it from rotating. The inner sleeve 10 then moves the inner adapting sleeve 8, which in turn moves the linkage block 28 via the linkage groove 29 on one side. The linkage block 28 then locks... Block 11 drives adjusting block 12 to slide along adjusting groove 13. Due to the unique inclined structural design of adjusting block 12 and adjusting groove 13, adjusting block 12 drives locking block 11 to move outward while sliding along adjusting groove 13. Then, locking block 11 drives linkage block 28 to slide along linkage groove 29. Then, the inner wall of locking block 11 no longer clamps the outer end of adapting rod 9. Then, double-headed cylinder 26 is opened, causing double-headed cylinder 26 to drive piston rods 27 on both sides to move inward synchronously. Then, piston rods 27 drive clamping frame 4 and connecting sleeve 3 to move inward synchronously. Then, one end of adapting rod 9 will first contact the outer surface of the component. Then, clamping frame 4 continues to drive connecting sleeve 3 to move. Then, one end of adapting rod 9 is no longer moving due to force.And the corresponding adapting plate 6 no longer moves. Then the connecting sleeve 3 drives the inner sleeve 10, the adapting sleeve 8, and the fixing frame 5 to slide along the adapting rod 9. Then the fixing frame 5 drives the corresponding adapting spring 7 to stretch to different degrees. The adapting rod 9 that is not in contact with the outer surface of the part continues to move with the connecting sleeve 3. When the ball set at one end of all the adapting rods 9 contacts the outer surface of the part, the double-headed cylinder 26 is closed. Then the control sleeve 2 is rotated in the opposite direction. The control sleeve 2 will drive the locking rod 30 to rotate in the opposite direction. And the inner sleeve 10 is limited by the threads on the inner wall of the control sleeve 2 and the outer wall of the inner sleeve 10, as well as the linkage block 28 and the linkage groove 29. The fixing frame 5 and the adapting rod 9 limit the adapting sleeve 8. The inner sleeve 10 is positioned so that it does not rotate. Then, the inner sleeve 10 will drive the adapting sleeve 8 to slide and reset along the adapting rod 9. Then, one side of the inner sleeve 10 will push the locking block 11 to slide and reset, and the locking block 11 will drive the adjusting block 12 on one side to slide and reset along the adjusting groove 13. Then, the adjusting block 12 will drive the locking block 11 to converge and reset inward, and the locking block 11 will drive the linkage block 28 to slide and reset along the linkage groove 29. Then, the inner wall of the locking block 11 will lock the outer wall of the adapting rod 9 again. When the outer wall of the adapting rod 9 is completely locked, the cooperating spring 31 will just drive the locking rod 30 to slide and reset into the original locking groove 32. At this time, the rotation of the control sleeve stops. 2. Then, rotate the return plate 14 again, causing it to rotate the adapter groove 21, adapter hole 18, and return block 19. The return block 19 then engages with the connecting block 20 to press the return spring 22. When the adapter hole 18 rotates to a position concentric with the adapter plate 15, the adapter spring 33 pushes the locking sleeve 17 to slide the limiting block 35 along the limiting groove 34 to reset. The locking sleeve 17 also drives the adapter rod 16 and the adapter plate 15 to slide to reset. When the adapter spring 33 is fully reset, the adapter plate 15 at the top of the adapter rod 16 moves to the original side of the return plate 14. Then, release the return plate 14, and the return spring 22 pushes the return block. 19 is reset, and then the return block 19 will drive the adapter hole 18 and adapter groove 21 to rotate and reset via the return plate 14, so that the adapter groove 21 and adapter hole 18 move to a position not related to the adapter rod 16 and adapter plate 15. Then the adapter rod 16 and adapter plate 15 cooperate to support the lock sleeve 17 on one side of the return plate 14. With the upper limit block 35 and limit groove 34 limiting the lock sleeve 17, the lock sleeve 17 is locked. Then the inner wall of the lock sleeve 17 limits the outer end of the locking rod 30, so that the locking rod 30 cannot move. Then the locking rod 30 and the locking groove 32 cooperate to completely lock the control sleeve 2, thereby ensuring structural stability and thus ensuring stable clamping of the parts.

[0039] Please see Figures 1-3As one embodiment of the grinding device: the grinding device includes a lifting assembly 36, a grinding assembly 37 and a mechanical claw assembly 38, the grinding assembly 37 is installed on one side of one of the lifting assemblies 36 and the mechanical claw assembly 38 is installed on the other side of the lifting assembly 36.

[0040] A conveyor 39 is detachably mounted on the base 1. The conveyor 39 is located on both sides of the placement platform 25. A bracket 40 is detachably mounted on the base 1. A mounting bracket 41 is detachably mounted on the top of the bracket 40. A longitudinal moving component 42 is detachably mounted above the mounting bracket 41. A transverse moving component 43 is slidably mounted above the longitudinal moving component 42. Both lifting components 36 are mounted on one side of the transverse moving component 43.

[0041] More specifically, when the equipment is needed, the automotive parts to be ground are first placed on the conveyor 39 on the left side. The parts are then transported to the other end of the conveyor 39. Next, the longitudinal movement assembly 42 on the mounting bracket 41 is opened, allowing it to slide along the mounting bracket 41 via a drive mechanism. When it moves directly above the left conveyor 39, the drive mechanism of the longitudinal movement assembly 42 is closed, and the drive mechanism of the transverse movement assembly 43 is opened. This causes the transverse movement assembly 43 to move the mechanical gripper assembly 38 directly above the parts, and then drives the corresponding lifting assembly 36 to move... The lifting assembly 36 drives the mechanical gripper assembly 38 to descend, clamping the part. Then, the lifting assembly 36 is driven in reverse to raise the mechanical gripper assembly 38 and the clamped part. The transverse and longitudinal traverse assemblies 43 and 42 are then driven in reverse to move the mechanical gripper assembly 38 directly above the placement platform 25. The clamped part is then placed onto the platform 25 via the mechanical gripper assembly 38 and the lifting assembly 36 on one side. The lifting assembly 36 then raises the mechanical gripper assembly 38 again, and the clamping device stably holds the part. Then... The drive lateral movement component 43 moves the grinding assembly 37 and its side-mounted lifting component 36 directly above the placement table 25. Then, the grinding assembly 37 and its side-mounted lifting component 36 are engaged to perform precision grinding of the parts. After grinding, the grinding assembly 37 is closed, and the side-mounted lifting component 36 lifts the grinding assembly 37. The lateral movement component 43 is then driven again, causing it to move the mechanical gripper assembly 38 and its side-mounted lifting component 36 back to directly above the placement table 25. The clamping device then stops clamping the parts. The machine gripper assembly 38 and the lifting assembly 36 on one side of it clamp and pick up the polished parts. Then, through the cooperation of the transverse and longitudinal components 43 and 42, the machine gripper assembly 38 and the clamped parts are moved above the right conveyor 39. The machine gripper assembly 38 and the lifting assembly 36 on one side of it then place the polished parts onto the right conveyor 39. The machine gripper assembly 38 is then raised, and the right conveyor 39 is opened so that the right conveyor 39 transports the polished parts to the next process. By repeating the above steps, mechanized continuous polishing can be achieved.

[0042] In summary, when the entire equipment is in use or running: when it is necessary to clamp parts, first place the parts to be ground on the placement table 25, then open the hydraulic cylinder 23, so that the hydraulic cylinder 23 drives the placement table 25 to rise and fall through the hydraulic rod 24 connected to the output end, thereby adjusting the placement height of the parts. After the adjustment is appropriate, close the hydraulic cylinder 23, then rotate the return plate 14, so that the return plate 14 drives the adapter hole 18 and the adapter groove 21 to rotate. At the same time, the return plate 14 will drive the return block 19 to rotate, and then the return block 19 will cooperate with the connecting block 20 to compress the return spring 22. When the return spring 22 is compressed to the limit, the adapter hole 18 just rotates to the position concentric with the adapter plate 15. At this time, push the locking sleeve 17, and the locking sleeve 17 drives the limit block. As lock rod 30 slides along limiting groove 34, it causes adapter rod 16 and adapter plate 15 to gradually slide into adapter hole 18. Lock sleeve 17 and return plate 14 cooperate to compress adapter spring 33. When adapter spring 33 is compressed to its limit, adapter plate 15 near lock sleeve 17 passes through adapter hole 18 and reaches the other side of return plate 14. At this time, return plate 14 is released, return spring 22 pushes return block 19 to drive return plate 14 to rotate in the opposite direction. Then return plate 14 will drive adapter hole 18 and adapter groove 21 to rotate in the opposite direction. Then adapter rod 16 will enter adapter groove 21. Then adapter rod 16 and adapter plate 15 near lock sleeve 17 cooperate to limit lock sleeve 17 to return plate 14. Then lock sleeve 17 no longer limits lock rod 30. Then, the control sleeve 2 is rotated, which causes multiple locking rods 30 slidably mounted on the side wall to move. The inner wall of the locking groove 32 on the outer side of the connecting sleeve 3 then presses against the inner end of the locking rod 30. Due to the rounded corners at the edges of the locking groove 32 and the rounded corners at the ends of the locking rods 30, the inner end of the locking rod 30 slides out of the locking groove 32, and the outer end of the locking rod 30 stretches the cooperating spring 31. Simultaneously, because the inner wall of the control sleeve 2 is connected to the outer wall of the inner sleeve 10 via threads, and the cooperation of the linkage block 28 and the linkage groove 29 limits the inner sleeve 10, preventing it from rotating. The inner sleeve 10 then moves the inner adapting sleeve 8, which in turn moves the linkage block 28 via the linkage groove 29 on one side. The linkage block 28 then... The locking block 11 drives the adjusting block 12 to slide along the adjusting groove 13. Due to the unique inclined structural design of the adjusting block 12 and the adjusting groove 13, the adjusting block 12 drives the locking block 11 to move outward while sliding along the adjusting groove 13. Then, the locking block 11 drives the linkage block 28 to slide along the linkage groove 29. Then, the inner wall of the locking block 11 no longer clamps the outer end of the adapting rod 9. Then, the double-headed cylinder 26 is opened, so that the double-headed cylinder 26 drives the piston rods 27 on both sides to move inward synchronously. Then, the piston rods 27 drive the clamping frame 4 and the connecting sleeve 3 to move inward synchronously. Then, one end of the adapting rod 9 will first contact the outer surface of the component. Then, the clamping frame 4 continues to drive the connecting sleeve 3 to move. Then, one end of the adapting rod 9 will no longer move under force.And the corresponding adapting plate 6 no longer moves. Then the connecting sleeve 3 drives the inner sleeve 10, the adapting sleeve 8, and the fixing frame 5 to slide along the adapting rod 9. Then the fixing frame 5 drives the corresponding adapting spring 7 to stretch to different degrees. The adapting rod 9 that is not in contact with the outer surface of the part continues to move with the connecting sleeve 3. When the ball set at one end of all the adapting rods 9 contacts the outer surface of the part, the double-headed cylinder 26 is closed. Then the control sleeve 2 is rotated in the opposite direction. The control sleeve 2 will drive the locking rod 30 to rotate in the opposite direction. And the inner sleeve 10 is limited by the threads on the inner wall of the control sleeve 2 and the outer wall of the inner sleeve 10, as well as the linkage block 28 and the linkage groove 29. The fixing frame 5 and the adapting rod 9 limit the adapting sleeve 8. The inner sleeve 10 is positioned so that it does not rotate. Then, the inner sleeve 10 will drive the adapting sleeve 8 to slide and reset along the adapting rod 9. Then, one side of the inner sleeve 10 will push the locking block 11 to slide and reset, and the locking block 11 will drive the adjusting block 12 on one side to slide and reset along the adjusting groove 13. Then, the adjusting block 12 will drive the locking block 11 to converge and reset inward, and the locking block 11 will drive the linkage block 28 to slide and reset along the linkage groove 29. Then, the inner wall of the locking block 11 will lock the outer wall of the adapting rod 9 again. When the outer wall of the adapting rod 9 is completely locked, the cooperating spring 31 will just drive the locking rod 30 to slide and reset into the original locking groove 32. At this time, the rotation of the control sleeve stops. 2. Then, rotate the return plate 14 again, causing it to rotate the adapter groove 21, adapter hole 18, and return block 19. The return block 19 then engages with the connecting block 20 to press the return spring 22. When the adapter hole 18 rotates to a position concentric with the adapter plate 15, the adapter spring 33 pushes the locking sleeve 17 to slide the limiting block 35 along the limiting groove 34 to reset. The locking sleeve 17 also drives the adapter rod 16 and the adapter plate 15 to slide to reset. When the adapter spring 33 is fully reset, the adapter plate 15 at the top of the adapter rod 16 moves to the original side of the return plate 14. Then, release the return plate 14, and the return spring 22 pushes the return block. 19 is reset, and then the return block 19 will drive the adapter hole 18 and adapter groove 21 to rotate and reset via the return plate 14, so that the adapter groove 21 and adapter hole 18 move to a position not related to the adapter rod 16 and adapter plate 15. Then the adapter rod 16 and adapter plate 15 cooperate to support the lock sleeve 17 on one side of the return plate 14. With the upper limit block 35 and limit groove 34 limiting the lock sleeve 17, the lock sleeve 17 is locked. Then the inner wall of the lock sleeve 17 limits the outer end of the locking rod 30, so that the locking rod 30 cannot move. Then the locking rod 30 and the locking groove 32 cooperate to completely lock the control sleeve 2, thereby ensuring structural stability and thus ensuring stable clamping of the parts.

[0043] When the equipment is needed, first place the automotive parts to be ground onto the conveyor 39 on the left side. Then, transport the parts to the other end of the conveyor 39. Next, open the longitudinal movement assembly 42 on the mounting bracket 41, allowing the longitudinal movement assembly 42 to slide along the mounting bracket 41 via a drive mechanism. When it moves directly above the left conveyor 39, close the drive mechanism included in the longitudinal movement assembly 42, and then open the drive mechanism included in the transverse movement assembly 43. This causes the transverse movement assembly 43 to move the mechanical gripper assembly 38 directly above the parts, and then drive the corresponding lifting assembly 36 to operate, thus... The lifting assembly 36 drives the mechanical gripper assembly 38 to descend, clamping the part. Then, the lifting assembly 36 reverses direction, lifting the mechanical gripper assembly 38 and the clamped part. Next, the horizontal and vertical movement assemblies 43 and 42 reverse direction, moving the mechanical gripper assembly 38 directly above the placement platform 25. The clamped part is then placed onto the platform 25 via the mechanical gripper assembly 38 and the lifting assembly 36 on one side. The lifting assembly 36 then lifts the mechanical gripper assembly 38 again, stably clamping the part. Finally, the lifting assembly 36 drives the mechanical gripper assembly 38 to rise again. The lateral movement component 43 moves the grinding assembly 37 and its side-mounted lifting component 36 directly above the placement table 25. Then, the grinding assembly 37 and its side-mounted lifting component 36 are engaged to perform precision grinding of the parts. After grinding, the grinding assembly 37 is closed, and the side-mounted lifting component 36 lifts the grinding assembly 37. The lateral movement component 43 is then activated again, causing it to move the mechanical gripper assembly 38 and its side-mounted lifting component 36 back above the placement table 25. The clamping device then releases the parts from the gripper. The mechanical gripper assembly 38 and the lifting assembly 36 on one side clamp and pick up the polished parts. Then, through the cooperation of the transverse and longitudinal components 43 and 42, the mechanical gripper assembly 38 and the clamped parts are moved above the right conveyor 39. The mechanical gripper assembly 38 and the lifting assembly 36 on one side then place the polished parts onto the right conveyor 39. The mechanical gripper assembly 38 is then raised, and the right conveyor 39 is opened, so that the right conveyor 39 transports the polished parts to the next process. By repeating the above steps, mechanized continuous polishing can be achieved.
