Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, specifically to an aluminum alloy automotive parts processing platform. Background Technology

[0002] The aluminum alloy automotive parts special processing platform is a special processing platform developed and designed to address the characteristics of aluminum alloy materials, such as low hardness, easy deformation during processing, and easy surface scratches.

[0003] Patent publication number CN221911648U relates to an aluminum alloy automotive parts processing platform, belonging to the field of automotive parts processing technology. It includes a base plate with a top plate mounted on top. A lifting mechanism and a control mechanism are installed between the base plate and the top plate. A clamping mechanism is mounted on the top of the top plate. The lifting mechanism includes a cylinder rotatably connected to the middle of the top of the base plate. A fixed plate is rotatably connected to the output end of the cylinder. This patent uses the cylinder to drive the first and second connecting arms to rotate, thereby raising and lowering the top plate. When not in use, it can be stored to save space; when needed, it can be opened for processing automotive parts. A motor drives a bidirectional threaded rod to rotate, thereby causing a threaded block to slide along a limiting post, which clamps and fixes the automotive parts.

[0004] In the aforementioned patent, a motor drives a bidirectional threaded rod to rotate, causing the threaded blocks to translate towards or away from each other, thereby clamping and fixing automotive parts and ensuring the positional stability of the parts during processing. However, since the clamping surface of the threaded blocks is a planar structure, when clamping round or arc-shaped automotive parts, the planar surface and the arc-shaped surface cannot form a close-fitting surface contact clamping, making it difficult to provide sufficient clamping force and achieve effective fixation. It is necessary for the operator to stop the machine and replace it with a special fixture adapted to the arc-shaped surface, which seriously reduces the overall processing efficiency. At the same time, during the process of the bidirectional threaded rod driving the threaded blocks on both sides to translate towards each other, it is necessary to avoid direct collision between the threaded blocks on both sides to prevent structural damage. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an aluminum alloy automotive parts processing platform, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an aluminum alloy automotive parts processing platform, comprising a base, a U-shaped bracket fixedly mounted on the top of the base for supporting automotive parts with a surface area larger than its top bearing surface, a mounting seat fixedly mounted on the top of the base, a linear guide rail provided on the mounting seat, a servo motor fixedly mounted on the surface of the mounting seat, and a lead screw rotatably mounted on the inner wall of the mounting seat. The output end of the servo motor is coaxially and fixedly connected to the lead screw via a coupling. Two slides are threadedly connected to the lead screw, which drives the two slides to perform opposite or opposite translational movements along the linear guide rail. Starting the servo motor drives the lead screw to rotate clockwise, thereby moving the two slides. The system also includes: a base plate, which is fixedly mounted on the top of the slide table; a rotating tube, which is rotatably mounted on the top of the base plate; a lifting tube, which is slidably mounted on the inner wall of the rotating tube; a mounting plate, which is fixedly mounted on the top of the lifting tube, and the lifting tube is used to drive the mounting plate to move vertically up and down along the axis of the rotating tube; the slide table drives the base plate to move towards the Z-shaped support direction; the base plate drives the lifting tube and the mounting plate to move synchronously through the rotating tube; a spring, which is disposed between the rotating tube and the mounting plate; a rectangular clamp, which is fixedly mounted on the top of the mounting plate, and the rectangular clamp is used to clamp rectangular structural components; and an arc-shaped clamp, which is fixedly mounted on the top of the mounting plate, and the arc-shaped clamp is used to clamp circular structural components.

[0007] According to the above technical solution, a rectangular guide groove is provided at the top of the rotating tube, and a protrusion adapted to the rectangular guide groove is fixedly installed on the circumferential surface of the lifting tube. The protrusion fits against the inner wall of the rectangular guide groove, and the lifting tube applies a lateral thrust to the rectangular guide groove of the rotating tube through the protrusion, driving the rotating tube to rotate synchronously with the lifting tube.

[0008] According to the above technical solution, four sleeves are fixedly installed on the top of the substrate, and four rods are fixedly installed on the bottom of the mounting plate. The four rods are arranged corresponding to the four sleeves. The rods are in contact with the inner wall of the sleeves. The rods move upward and gradually detach from the inner wall of the sleeves, thereby releasing the rotation constraint on the mounting plate.

[0009] According to the above technical solution, rubber anti-slip pads are provided on the clamping surfaces of both the rectangular clamp and the arc clamp. The rubber anti-slip pads are used to increase the friction of the clamping surface. The rubber anti-slip pads first make flexible contact with the side wall of the rectangular component, and then the rectangular clamp applies a controllable clamping force to it until it is clamped at the preset position on the top of the Z-shaped bracket.

[0010] According to the above technical solution, the insertion rod is provided with a protective device to improve the safety of clamp replacement, and the U-shaped bracket is provided with a limiting device to prevent excessive displacement of the clamp; the protective device includes a sleeve ring, a rubber buffer ring, a support plate and a main friction plate. The sleeve ring is fixedly installed on the circumferential surface of the insertion rod. When the mounting plate moves the insertion rod upward, the sleeve ring fixed to the insertion rod moves upward synchronously. The rubber buffer ring is located at the bottom of the sleeve ring. The support plate is fixedly installed on the surface of the sleeve ring. The main friction plate is located on the side of the support plate away from the sleeve ring. The bottom of the rubber buffer ring contacts the top of the sleeve, and the rubber buffer ring moves downward to flexibly contact the top of the sleeve.

[0011] According to the above technical solution, a positioning seat is fixedly installed on the top of the substrate. A circular hole is opened on the surface of the positioning seat. An insertion slot communicating with the circular hole is opened on the top of the positioning seat. An insertion plate is provided in the insertion slot. An internal threaded through hole is opened on the surface of the insertion plate. The insertion plate is fixedly connected to the positioning seat by fastening screws. By loosening the fastening screws and then pulling the round rod upward, the insertion plate can be removed to maintain or replace the secondary friction plate. Secondary friction plates are provided on both sides of the insertion plate. A round rod is fixedly installed on the surface of the insertion plate. The round rod contacts the inner wall of the insertion slot. The main friction plate and the secondary friction plate are in contact. The continuous static friction force generated between the main friction plate and the secondary friction plate is transmitted to the insertion rod through the support plate and the sleeve ring.

[0012] According to the above technical solution, the limiting device includes a loading frame, a moving rod, a limiting baffle, a pull rod, a tension spring, and a locking block. The positioning seat contacts the limiting baffle during displacement, and the limiting baffle effectively blocks it. The loading frame is fixedly mounted on the surface of the U-shaped bracket. The moving rod is slidably installed inside the loading frame. The limiting baffle is slidably mounted on one side surface of the loading frame. The limiting baffle is fixedly connected to the circumferential surface of the moving rod. The pull rod is slidably mounted on the inner wall of the moving rod. The tension spring is disposed between the moving rod and the pull rod. The tension spring is stretched during the movement of the pull rod, causing it to undergo elastic deformation. The locking block is fixedly mounted on the circumferential surface of the pull rod. The side of the loading frame near the locking block has several locking slots. The several locking slots are equidistantly distributed along the sliding direction of the moving rod. The locking block fits against the inner wall of the locking slot.

[0013] According to the above technical solution, a buffer sleeve is slidably installed on the side surface of the limiting baffle away from the moving rod, and an elastic rod is fixedly inserted through the side of the limiting baffle near the buffer sleeve. The elastic rod is fixedly connected to the inner wall of the buffer sleeve. When the buffer sleeve slides, it squeezes the elastic rod, causing the elastic rod to undergo elastic deformation.

[0014] This invention provides an aluminum alloy automotive parts processing platform. It has the following advantages:

[0015] (1) In this aluminum alloy automotive parts processing platform, the lifting tube drives the convex strip to move upward synchronously along the rectangular guide groove, while the insertion rod gradually separates from the inner wall of the sleeve. Through the cooperation of the insertion rod and the sleeve, it can not only provide accurate and reliable positioning for the clamping adjustment of the mounting plate, but also effectively enhance the stability of the mounting plate in the clamping operation, and ensure the accuracy of the aluminum alloy automotive parts in the processing. At the same time, the mounting plate rotates into place and controls its smooth downward movement, which can complete the replacement of the rectangular clamp and the arc clamp. Through standardized operation, the position of the rectangular clamp and the arc clamp can be quickly interchanged, so that the workers can flexibly switch the appropriate clamp according to the shape of the aluminum alloy automotive parts, effectively improving the flexibility of the processing operation.

[0016] (2) When the main friction plate and the secondary friction plate of the aluminum alloy automotive parts processing platform are in a stable contact state, the continuous static friction force generated between them, through the stable static friction force generated by the tight contact between the main friction plate and the secondary friction plate, combined with the elastic constraint of the spring, effectively suppresses the shaking of the mounting plate during the clamping operation. At the same time, the main friction plate moves down and the secondary friction plate continuously rubs to generate resistance. This frictional resistance can effectively slow down the downward movement speed of the insertion rod. Through the continuous friction between the main friction plate and the secondary friction plate, a stable resistance is generated to slow down the downward movement speed of the insertion rod, which can effectively avoid collisions caused by improper downward control during the clamping operation and effectively ensure the safety of the operation.

[0017] (3) The aluminum alloy automotive parts processing platform has a limit baffle that effectively blocks the positioning seat through a buffer sleeve. Through the flexible buffer of the buffer sleeve and the elastic rod, it can effectively block the positioning seat in case of an emergency, thereby avoiding damage and safety risks caused by the collision between the mounting plate and the Z-shaped bracket. At the same time, the limit baffle can be stored under the Z-shaped bracket. The activation and storage states of the limit baffle can be flexibly switched by pulling and translating the lever, effectively reducing the adjustment time to meet different processing needs.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1 - Figure 10One embodiment of the present invention is: an aluminum alloy automotive parts processing platform, including a base 1, a U-shaped bracket 2 fixedly mounted on the top of the base 1, the U-shaped bracket 2 being used to support automotive parts with a surface area larger than its top bearing surface, a mounting base 3 fixedly mounted on the top of the base 1, a linear guide rail provided on the mounting base 3, a servo motor 4 fixedly mounted on the surface of the mounting base 3, a lead screw 5 rotatably mounted on the inner wall of the mounting base 3, the output end of the servo motor 4 being coaxially fixedly connected to the lead screw 5 via a coupling, two slides 6 being threadedly connected to the lead screw 5, the lead screw 5 being used to drive the two slides 6 to achieve opposite or opposite translational movements along the linear guide rail, and further including: a base plate 7, the base plate 7 being fixedly mounted on the top of the slides 6; and a rotating tube 8, the rotating tube 8 being rotatably mounted on the base 1. The components include: a top plate 7; a lifting tube 9, which is slidably mounted on the inner wall of a rotating tube 8; a mounting plate 10, which is fixedly mounted on the top of the lifting tube 9 and drives the mounting plate 10 to move vertically up and down along the axis of the rotating tube 8; a spring 11, which is positioned between the rotating tube 8 and the mounting plate 10; a rectangular clamp 12, which is fixedly mounted on the top of the mounting plate 10 and is used to clamp rectangular structural parts; and an arc-shaped clamp 13, which is fixedly mounted on the top of the mounting plate 10 and is used to clamp circular structural parts. Through standardized operation, the positions of the rectangular clamp 12 and the arc-shaped clamp 13 can be quickly interchanged, allowing workers to flexibly switch between suitable clamps according to the shape of the aluminum alloy automotive parts.

[0031] The top of the rotating tube 8 is provided with a rectangular guide groove. A protrusion 14 that matches the rectangular guide groove is fixedly installed on the circumference of the lifting tube 9. The protrusion 14 fits against the inner wall of the rectangular guide groove. The fit between the protrusion 14 and the rectangular guide groove ensures that when the mounting plate 10 is rotated, the rotating tube 8 can rotate synchronously with the lifting tube 9, thus ensuring the stability of the spring 11.

[0032] Four sleeves 15 are fixedly installed on the top of the substrate 7, and four insertion rods 16 are fixedly installed on the bottom of the mounting plate 10. The four insertion rods 16 are correspondingly set with the four sleeves 15. The insertion rods 16 fit against the inner wall of the sleeves 15. Through the cooperation of the insertion rods 16 and the sleeves 15, not only can the clamping adjustment of the mounting plate 10 be provided with accurate and reliable positioning, but the stability of the mounting plate 10 in the clamping operation can also be effectively enhanced.

[0033] Both the rectangular clamp 12 and the arc-shaped clamp 13 are provided with rubber anti-slip pads on their clamping surfaces. The rubber anti-slip pads are used to increase the friction of the clamping surfaces and prevent damage to aluminum alloy automotive parts by setting the rubber anti-slip pads.

[0034] In this embodiment, when processing rectangular aluminum alloy automotive parts, the rectangular parts are first placed at the center of the top of the U-shaped bracket 2. Then, the servo motor 4 is started, driving the lead screw 5 to rotate clockwise, which in turn drives the two slides 6 to move towards each other along the linear guide rail. During this process, the slides 6 simultaneously drive the base plate 7 to move towards the U-shaped bracket 2. The base plate 7 drives the lifting tube 9 and the mounting plate 10 to move synchronously through the rotating tube 8. The mounting plate 10 then drives the rectangular clamp 12 and the arc clamp 13 to move synchronously, so that the rectangular clamps 12 on both sides of the U-shaped bracket 2 are in a state of moving towards each other. During the translation, the rubber anti-slip pads on the rectangular clamps 12 first make flexible contact with the side wall of the rectangular parts. Then, the rectangular clamps 12 apply a controllable clamping force to it until it is clamped at the preset position on the top of the U-shaped bracket 2. At this time, the servo motor 4 stops running, and the safe and reliable clamping operation of the rectangular aluminum alloy parts is completed.

[0035] When processing round aluminum alloy automotive parts, the round part is first placed at the center of the top of the Z-shaped bracket 2. Then, the mounting plate 10 is lifted upwards. As the mounting plate 10 moves upwards, the spring 11 is stretched, causing it to undergo elastic deformation. At the same time, the rectangular clamp 12 and the arc-shaped clamp 13 fixed to its top, as well as the lifting tube 9 and the insert rod 16 fixed to its bottom, move upwards synchronously. During this process, the lifting tube 9 drives the protrusion 14 to move upwards synchronously along the rectangular guide groove, while the insert rod 16 gradually disengages from the inner wall of the sleeve 15, releasing the rotational constraint on the mounting plate 10. Then, the... The mounting plate 10 rotates 180 degrees, allowing the rectangular clamp 12 and the arc-shaped clamp 13 to interchange positions. At the same time, the mounting plate 10 drives the lifting tube 9 and the insert rod 16 to rotate synchronously. During the rotation, the lifting tube 9 applies a lateral thrust to the rectangular guide groove of the rotating tube 8 through the protrusion 14, driving the rotating tube 8 to rotate synchronously with the lifting tube 9. Through the cooperation of the insert rod 16 and the sleeve 15, it can not only provide accurate and reliable positioning for the clamping adjustment of the mounting plate 10, but also effectively enhance the stability of the mounting plate 10 in the clamping operation and ensure the precision of aluminum alloy automotive parts in the processing.

[0036] Once the mounting plate 10 is rotated into position, it is controlled to move downwards smoothly, allowing the spring 11, which is in a state of tension deformation, to gradually return to its original state. During this process, the insertion rod 16 moves downwards synchronously with the mounting plate 10 and is precisely inserted into the corresponding sleeve 15. After the replacement of the rectangular clamp 12 and the arc clamp 13 is completed, the servo motor 4 is started to drive the lead screw 5 to rotate clockwise, thereby driving the two slides 6 to move towards each other along the linear guide rail. The slides 6 repeat the transmission described above, so that the arc clamps 13 on both sides of the Z-shaped bracket 2 are in a state of moving towards each other. During the movement, the rubber anti-slip pads on the arc clamps 13 first make flexible contact with the circumference of the circular part, and then the arc clamps 13 apply a controllable clamping force to it until it is clamped at the preset position on the top of the Z-shaped bracket 2, thus completing the safe and reliable clamping of the circular aluminum alloy part. Through standardized operation, the position exchange of the rectangular clamp 12 and the arc clamp 13 can be completed quickly, allowing the operator to flexibly switch the appropriate clamps according to the shape of the aluminum alloy automotive parts, effectively improving the flexibility of the processing operation.

[0037] Please see Figure 1 - Figure 10 Based on the above embodiments, in another embodiment of the present invention, the insertion rod 16 is provided with a protective device for improving the safety of clamp replacement, and the U-shaped bracket 2 is provided with a limiting device for preventing excessive displacement of the clamp; the protective device includes a sleeve ring 21, a rubber buffer ring 22, a support plate 23 and a main friction plate 24. The sleeve ring 21 is fixedly installed on the circumferential surface of the insertion rod 16, the rubber buffer ring 22 is disposed at the bottom of the sleeve ring 21, the support plate 23 is fixedly installed on the surface of the sleeve ring 21, and the main friction plate 24 is disposed on the side surface of the support plate 23 away from the sleeve ring 21. The bottom of the rubber buffer ring 22 contacts the top of the sleeve 15. By setting the rubber buffer ring 22, the safety of the sleeve ring 21 when it moves down with the insertion rod 16 is achieved.

[0038] A positioning seat 25 is fixedly installed on the top of the base plate 7. A circular hole is opened on the surface of the positioning seat 25. An insertion groove communicating with the circular hole is opened on the top of the positioning seat 25. An insertion plate 26 is provided in the insertion groove. An internal threaded through hole is opened on the surface of the insertion plate 26. The insertion plate 26 is fixedly connected to the positioning seat 25 by fastening screws. A secondary friction plate 27 is provided on both sides of the insertion plate 26. A round rod 28 is fixedly installed on the surface of the insertion plate 26. The round rod 28 contacts the inner wall of the insertion groove. The main friction plate 24 and the secondary friction plate 27 are in contact. The stable static friction force generated by the close contact between the main friction plate 24 and the secondary friction plate 27, combined with the elastic constraint of the spring 11, effectively suppresses the shaking of the mounting plate 10 during the clamping operation.

[0039] The limiting device includes a loading frame 31, a moving rod 32, a limiting baffle 33, a pull rod 34, a tension spring 35, and a locking block 36. The loading frame 31 is fixedly inserted through the surface of the Z-shaped bracket 2. The moving rod 32 is slidably installed inside the loading frame 31. The limiting baffle 33 is slidably inserted through one side surface of the loading frame 31 and is fixedly connected to the circumferential surface of the moving rod 32. The pull rod 34 is slidably installed on the inner wall of the moving rod 32. The tension spring 35 is disposed between the moving rod 32 and the pull rod 34. The locking block 36 is fixedly installed on the circumferential surface of the pull rod 34. Several locking slots are provided on the side of the loading frame 31 near the locking block 36. The several locking slots are equidistantly distributed along the sliding direction of the moving rod 32. The locking block 36 fits against the inner wall of the locking slot. By pulling and translating the pull rod 34, the activation and retraction states of the limiting baffle 33 can be flexibly switched, effectively reducing adjustment time and meeting different processing requirements.

[0040] A buffer sleeve 37 is slidably installed on the side of the limiting baffle 33 away from the moving rod 32. An elastic rod 38 is fixedly inserted through the side of the limiting baffle 33 near the buffer sleeve 37. The elastic rod 38 is fixedly connected to the inner wall of the buffer sleeve 37. Through the flexible buffering of the buffer sleeve 37 and the elastic rod 38, the positioning seat 25 can be effectively blocked in case of emergency, thereby avoiding damage and safety risks caused by the collision between the mounting plate 10 and the Z-shaped bracket 2.

[0041] In this embodiment, when clamping aluminum alloy automotive parts, the main friction plate 24 and the secondary friction plate 27 always maintain a stable contact. The continuous static friction force generated between them is transmitted to the insertion rod 16 through the support plate 23 and the sleeve ring 21, which can effectively improve the stability of the insertion rod 16 when it is in contact with the inner wall of the sleeve 15. In addition, with the spring 11 between the rotating tube 8 and the mounting plate 10, the resistance when the mounting plate 10 and the insertion rod 16 move upward can be effectively increased, avoiding the mounting plate 10 from moving upward unexpectedly during the clamping process. The stable static friction force generated by the tight contact between the main friction plate 24 and the secondary friction plate 27, combined with the elastic constraint of the spring 11, effectively suppresses the shaking of the mounting plate 10 during the clamping operation.

[0042] When the mounting plate 10 moves the insertion rod 16 upward, the sleeve ring 21 fixed to the insertion rod 16 moves upward synchronously. The sleeve ring 21 moves the rubber buffer ring 22 upward together, so that the rubber buffer ring 22 gradually separates from the top of the sleeve 15. At the same time, the sleeve ring 21 moves the main friction plate 24 upward synchronously through the support plate 23. During the upward movement, the friction between the main friction plate 24 and the auxiliary friction plate 27 generates resistance until the two completely disengage. At this time, the operator can smoothly perform the rotation operation of the mounting plate 10.

[0043] When the mounting plate 10 moves the insertion rod 16 downward, the sleeve ring 21 simultaneously moves the rubber buffer ring 22 and the support plate 23 downward. The support plate 23 then moves the main friction plate 24 downward. During this process, the main friction plate 24 first contacts the auxiliary friction plate 27, and then generates stable frictional damping during the continuous downward movement. This frictional damping can effectively slow down the downward movement speed of the insertion rod 16 until the insertion rod 16 moves to the bottom. The rubber buffer ring 22 is in flexible contact with the top of the sleeve 15. Through the continuous friction between the main friction plate 24 and the auxiliary friction plate 27, stable resistance is generated to slow down the downward movement speed of the insertion rod 16. This can effectively avoid collisions caused by improper downward control during the clamp replacement operation and effectively ensure the safety of the operation.

[0044] During the clamping phase, the lead screw 5 drives the two slides 6 to move in opposite directions. The slides 6 simultaneously drive the positioning seat 25 to move towards the Z-shaped bracket 2. During this process, if the aluminum alloy parts accidentally fall from the top of the Z-shaped bracket 2, the positioning seat 25 in displacement will first contact the buffer sleeve 37 and then apply a horizontal thrust to it, driving it to slide towards the limiting baffle 33. During the sliding, the buffer sleeve 37 will squeeze the elastic rod 38, causing the elastic rod 38 to undergo elastic deformation. The deformed elastic rod 38 will apply reverse elastic resistance to the buffer sleeve 37, gradually slowing down the displacement speed of the positioning seat 25 until the buffer sleeve 37 and the limiting baffle 33 are in contact. The limiting baffle 33 will effectively block the positioning seat 25 through the buffer sleeve 37. At the same time, the staff will shut off the servo motor 4 in time. Through the flexible buffer of the buffer sleeve 37 and the elastic rod 38, the positioning seat 25 can be effectively blocked in case of an emergency, thereby avoiding damage and safety risks caused by the collision between the mounting plate 10 and the Z-shaped bracket 2.

[0045] When the limit baffle 33 is not needed, the operator pulls the lever 34 outward. As the lever 34 moves, the tension spring 35 is stretched, causing it to elastically deform. Simultaneously, the lever 34 moves the locking block 36 away from the loading frame 31. The locking block 36 gradually disengages from the slot, releasing the constraint on the translation of the moving rod 32. Next, the operator controls the lever 34 to translate towards the center of the loading frame 31. The lever 34 drives the moving rod 32 and the locking block 36 to translate synchronously. The moving rod 32 then drives the limit baffle 33 to translate together until the locking block 36... 6. Align with the preset slot. At this time, the limiting baffle 33 is retracted under the Z-shaped bracket 2. The operator releases the pull rod 34, and the tension spring 35, which is in a deformed state, elastically recovers and drives the pull rod 34 to move back synchronously. The pull rod 34 then drives the locking block 36 to move closer to the loading frame 31 until the locking block 36 is in contact with the inner wall of the constraint slot, thus completing the translation constraint of the moving rod 32. By pulling and translating the pull rod 34, the activation and retraction states of the limiting baffle 33 can be flexibly switched, effectively reducing adjustment time and meeting different processing requirements.
