Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and more specifically, to an automotive parts grinding system. Background Technology

[0002] In the existing automotive parts processing field, the axle sleeve is an important part in the assembly of automotive parts or drive axle assemblies. It is usually shaped like a shaft on the outside and hollow inside. Before assembling the assembly, long-stored inventory needs to be externally processed to improve production quality.

[0003] A search revealed a quicklime grinding mill with patent publication number "CN 117161934 A," comprising a base, a support arm, a processing box, a turntable, a connecting rod, and a rust removal mechanism. The support arm is fixedly connected to the upper end of the base; the processing box is fixed to the upper end of the support arm; a turntable rotats inside the processing box; a connecting rod is fixed to the side wall of the turntable; and a rust removal mechanism is installed at the end of the connecting rod furthest from the turntable. This invention, by setting up a turntable, connecting rod, and rust removal mechanism, allows the axle sleeve to be welded to be fed into the processing box. By driving the turntable to rotate, the circumferential outer wall of the axle sleeve can be ground and rust-removed, preventing the rust oxide layer from affecting the welding quality.

[0004] The above technical features have the following shortcomings: Firstly, while the device can be used to grind half-sleeves of different diameters by controlling components such as adjusting screws, nuts, and connecting plates before actual processing, both adjusting screws need to be manually adjusted each time, requiring a certain level of skill. If there is an error in adjusting one end of the screw, it will inevitably affect the final grinding effect of the grinding wheel on the outer surface of the sleeve. Secondly, the fixing mechanism composed of a lifting rack, gears, and a clamping plate can be used to fix sleeves of different diameters. However, in actual processing, the lifting rack is located inside the sleeve, and its travel is affected by the inner diameter of the sleeve, thus affecting the grinding effect during processing. When the diameters of the same pipe differ significantly, it is impossible to achieve the desired fixing effect on the bushing. Furthermore, while the device achieves fixing by moving the clamping plate in the opposite direction within the fixing mechanism to clamp the inside of the bushing, in actual processing, some bushings have different specifications. For some longer bushings, processing is only done by fixing one end, inevitably causing the end furthest from the fixed end to wobble during processing, affecting the final grinding quality. Finally, the device lacks a structure for handling metal shavings and particulate dust generated during grinding, impacting the actual processing environment and increasing the difficulty of subsequent equipment cleaning.

[0005] Therefore, in view of this, the inventor has studied and improved the existing structure and its shortcomings, and provided a grinding system for automotive parts in order to achieve a more practical value. Summary of the Invention

[0006] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide an automotive parts grinding system. Through a multi-set grinding wheel linkage telescopic mechanism within the processing shroud, the grinding diameter can be adjusted synchronously with a single button, completely eliminating the cumbersome operation of repeatedly manually turning the adjusting screw as required in the prior art. A second gear ring drives all driven wheels to rotate in the same direction as the adjusting screw, ensuring absolutely consistent radial displacement of each grinding wheel and avoiding uneven grinding caused by unilateral errors. This significantly improves the efficiency and processing consistency of changing bushings of different specifications, reducing reliance on operator skill. Pneumatic clamps and reciprocating screw linkage support mechanisms are provided at both ends of the channel. The sliding seat can quickly adjust its spacing according to the bushing length. The arc-shaped clamp expands synchronously outward under the drive of the pneumatic grippers, forming a double-end internal support rigid fixation. This eliminates cantilever vibration, accommodates changes in inner diameter, and ensures that the long bushing rotates coaxially throughout the entire process. The grinding roundness and surface quality are significantly improved, further enhancing the practicality of the device and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automotive parts grinding system, comprising a base and a mounting plate disposed thereon, wherein a processing cover is rotatably mounted inside the mounting plate, and multiple grinding wheels are laterally arranged along the outer surface of the bushing inside the processing cover. The outer walls of the multiple grinding wheels are connected to a telescopic mechanism, which can simultaneously control the extension and retraction of the multiple grinding wheels relative to the outer wall of the bushing to achieve surface grinding of bushings of different specifications. A transverse movement mechanism for controlling the horizontal movement of the mounting plate is connected to the outer wall of the mounting plate. Both ends of the processing cover are provided with support mechanisms for fixing the bushing, improving the fixing effect of the bushing during processing. A reciprocating screw is threadedly connected to the lower part of the support mechanisms. A processing channel is provided inside the processing cover, and a first dust suction pipe communicating with the inside of the processing channel is connected to the outer wall of the processing cover for discharging metal chips and dust generated during processing.

[0008] Preferably, a first toothed ring is installed on the outer side wall of the processing cover, and a drive wheel is meshed with the outer side wall of the first toothed ring. The drive wheel is rotatably mounted on the mounting plate, and a drive motor is connected to one side of the drive wheel to drive the drive wheel to control the rotation of the first toothed ring and the processing cover.

[0009] Preferably, the telescopic mechanism includes multiple mounting seats that are slidably installed inside the processing cover. Each of the multiple grinding wheels is connected to a corresponding mounting seat by a second bolt. Each of the multiple mounting seats is threaded with an adjusting screw. The rod walls of each of the multiple adjusting screws are rotatably installed inside the processing cover. The other end of each of the multiple adjusting screws is connected to a driven wheel. One side of each of the multiple driven wheels is engaged with a second toothed ring, which is rotatably installed inside the processing cover.

[0010] Preferably, one side of one of the driven wheels is connected to a drive shaft, the other end of the drive shaft passes through the processing cover and extends to the outside, and the other end of the processing cover is threaded with a locking bolt and abuts against the outer wall of the processing cover.

[0011] Preferably, the lateral movement mechanism includes movable arms that are fixedly mounted on the outer wall of the mounting plate, two movable arms that are slidably mounted inside the base, and a first lead screw that is threaded into the interior of each of the two movable arms, and two first lead screws that are rotatably mounted inside the base.

[0012] Preferably, each of the two first lead screws has a matching partition on its opposite side, and both partitions are fixedly installed above the inner wall of the base to prevent dust from contaminating the outer wall of the first lead screw.

[0013] Preferably, the support mechanism includes a reciprocating lead screw rotatably mounted inside the base. The wall of the reciprocating lead screw is threadedly connected to a sliding seat. Both sliding seats are slidably mounted inside the base. Pneumatic clamps are detachably mounted inside both sliding seats. Two relatively horizontally movable pneumatic grippers are movably connected to each of the two pneumatic clamps. One side of each of the pneumatic grippers is connected to an arc-shaped clamping plate by a first bolt. The outer walls of the arc-shaped clamping plates extend into the bushing tube and match the inner wall of the bushing end.

[0014] Preferably, the inside of the processing cover is threaded with a sealing cover near the entry and exit ends of the processing channel, and both of the insides are connected with a flexible sealing curtain. The bushing enters the processing channel through the flexible sealing curtain for grinding.

[0015] Preferably, both flexible sealing curtains are composed of multiple slender plastic fibers arranged circumferentially, and form a seal at both ends of the processing channel during processing, thereby improving the dust removal effect of the first suction pipe.

[0016] Preferably, an external processing box is installed on the top of the base. A sealing door is hinged to the front of the external processing box. The other end of the first suction pipe passes through the external processing box and is connected to an air pump. The other end of the air pump is connected to an air purification device. A second suction pipe is connected to the end of the first suction pipe near the input end of the air pump. The other end of the second suction pipe is connected to a control valve. The input end of the control valve is connected to a dust collection box. The dust collection box is fixedly installed inside the external processing box and is used to process the external ambient air of the processing channel.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. This invention achieves one-click synchronous adjustment of the grinding diameter by using a multi-set grinding wheel linkage telescopic mechanism inside the processing cover, completely eliminating the tedious operation of manually turning the adjustment screw multiple times in the prior art; the second gear ring drives all driven wheels to rotate in the same direction as the adjustment screw, ensuring that the radial displacement of each grinding wheel is absolutely consistent, avoiding uneven grinding caused by unilateral error, significantly improving the changeover efficiency and processing consistency of bushings of different specifications, and reducing the dependence on the operator's skill level;

[0019] 2. To address the problem of wobbling at the distal end of the long shaft sleeve caused by the existing device relying solely on internal clamping at one end, this invention sets up a support mechanism at both ends of the processing channel that links pneumatic clamps with reciprocating lead screws; the sliding seat can quickly adjust the spacing according to the length of the shaft sleeve, and the arc-shaped clamping plate expands outward synchronously under the drive of the pneumatic gripper, forming a rigid fixation with double-end internal support, which not only eliminates cantilever vibration, but also accommodates changes in inner diameter, ensuring that the long shaft sleeve rotates coaxially throughout the entire process, and significantly improving the roundness and surface quality of the grinding.

[0020] 3. The system constructs a flexible barrier with an adaptive pipe diameter at both ends of the processing channel through a flexible sealing curtain and a sealing cover. Together with the first dust suction pipe, the second dust suction pipe and the air pump, it forms a double-loop negative pressure collection system. Metal scraps and dust are sealed in the processing channel and then discharged after being coarsely filtered by the dust collection box and finely filtered by the air purification device. This avoids the problem of dust escaping and polluting the workshop in existing technologies, reduces the frequency of equipment cleaning, extends the service life of precision components such as lead screws and guide rails, and achieves green production.

[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] As attached Figures 1 to 7 The illustrated automotive parts grinding system includes a base 1 and a mounting plate 7 mounted on top of it. A processing cover 8 is rotatably mounted inside the mounting plate 7. Multiple grinding wheels 18 are arranged laterally along the outer surface of the bushing inside the processing cover 8. The outer walls of the multiple grinding wheels 18 are connected to a telescopic mechanism, which can simultaneously control the multiple grinding wheels 18 to extend and retract relative to the outer wall of the bushing tube, thereby achieving surface grinding of bushing tubes of different specifications. A transverse movement mechanism that controls the horizontal movement of the mounting plate 7 is connected to the outer wall of the mounting plate 7. Support mechanisms for fixing the bushing tube are provided at both ends of the processing cover 8 to improve the fixing effect of the bushing tube. Before operation, the bushing tube to be processed is fixed by passing through the center of the grinding wheel 18 and inserting it into the outside of the support mechanism. A reciprocating screw 2 is threadedly connected to the bottom of the support mechanism. A processing channel 21 is provided inside the processing cover 8. A first dust suction pipe 22 connected to the processing channel 21 is connected to the outer wall of the processing cover 8 to discharge metal chips and dust generated during processing.

[0031] A first toothed ring 11 is installed on the outer wall of the processing cover 8. A drive wheel 12 is meshed with the outer wall of the first toothed ring 11. The drive wheel 12 is rotatably mounted on the mounting plate 7. A drive motor 13 is connected to one side of the drive wheel 12. The drive wheel 12 drives the first toothed ring 11 and the processing cover 8 to rotate, so that the grinding wheel 18 connected to the telescopic mechanism rotates together and performs grinding operation on the outer wall of the bushing. At the same time, under the action of the transverse mechanism, the rotating grinding wheel 18 is driven to move horizontally along the axis of the bushing to realize the grinding operation.

[0032] like Figure 4 and Figure 5 As shown, the telescopic mechanism includes multiple mounting seats 17 that are slidably installed inside the processing cover 8. Multiple grinding wheels 18 are connected to the corresponding mounting seats 17 by second bolts. Adjusting screws 16 are threadedly connected inside the multiple mounting seats 17. The rod walls of the multiple adjusting screws 16 are rotatably installed inside the processing cover 8. The other end of the multiple adjusting screws 16 is connected to a driven wheel 15. One side of the multiple driven wheels 15 is engaged with a second toothed ring 14. The second toothed ring 14 is rotatably installed inside the processing cover 8.

[0033] However, when it is necessary to process bushings of different diameters, a drive shaft 23 is connected to one side of one of the driven wheels 15. The other end of the drive shaft 23 passes through the processing cover 8 and extends to the outside. The other end of the processing cover 8 is threaded with a locking bolt 24 and abuts against the outer wall of the processing cover 8. By loosening the locking bolt 24 and rotating the drive shaft 23, the corresponding driven wheel 15 is controlled to rotate. In conjunction with the second gear ring 14, multiple driven wheels 15 are driven to rotate together, thereby driving the corresponding adjusting screw 16 to rotate together. At the same time, the corresponding mounting seat 17 is controlled to move along the inside of the processing cover 8 towards the center in opposite or opposite directions, thereby driving the corresponding grinding wheel 18 to move together, so as to realize the processing of the outer wall of bushings of different specifications. At the same time, the operation is convenient and simple, and it is easy to get started.

[0034] like Figure 1 and Figure 3 As shown, the transverse mechanism includes two movable arms 9 that are fixedly mounted on the outer wall of the mounting plate 7. Both movable arms 9 are slidably mounted inside the base 1. Both movable arms 9 are threadedly connected to a first lead screw 10. Both first lead screws 10 are rotatably mounted inside the base 1. Each of the two first lead screws 10 has a matching partition 32 on its opposite side. Both partitions 32 are fixedly mounted above the inner wall of the base 1 to prevent dust from contaminating the outer wall of the first lead screw 10. The first lead screw 10 is also driven by an external motor. Both lead screws rotate simultaneously, thereby driving the movable arms 9 and the mounting plate 7 to move left and right together. At the same time, the grinding wheel 18 inside the mounting plate 7 moves and grinds along the outer wall of the bushing tube.

[0035] like Figure 4 and Figure 5As shown, the support mechanism includes a reciprocating screw 2 rotatably mounted inside the base 1. The walls of the reciprocating screw 2 are threadedly connected to sliding seats 3. Both sliding seats 3 are slidably mounted inside the base 1. Pneumatic clamping seats 4 are detachably mounted inside each of the two sliding seats 3. Two relatively horizontally movable pneumatic grippers 5 are movably connected to each of the two pneumatic clamping seats 4. One side of each pneumatic gripper 5 is connected to an arc-shaped clamping plate 6 via a first bolt. The outer walls of the arc-shaped clamping plates 6 extend into the bushing tube and are flush with the inner wall of the bushing end. Matching, the reciprocating screw 2 is controlled to rotate by an external motor or other equipment, thereby driving the corresponding sliding seat 3 to move in the opposite or opposite direction. This causes the arc-shaped clamping plate 6 on the pneumatic gripper 5 to be used for processing shaft sleeves or shaft-shaped hollow accessories of different lengths. During processing, the pneumatic gripper 5 on the pneumatic chuck 4 is opened to unfold outward, thereby driving the arc-shaped clamping plate 6 inside the shaft sleeve to press against its inner wall for fixation. At the same time, the arc-shaped clamping plates 6 at both ends are fixed simultaneously, improving the stability of the processing operation and improving the processing quality.

[0036] like Figure 4 and Figure 5 As shown, the inside of the processing cover 8 is threaded with a sealing cover 19 near the entry and exit ends of the processing channel 21. The threaded connection facilitates subsequent maintenance. Both are connected with a flexible sealing curtain 20. The bushing enters the processing channel 21 for grinding by passing through the flexible sealing curtain 20.

[0037] Both flexible sealing curtains 20 are composed of multiple slender plastic fibers arranged circumferentially, and form a seal at both ends of the processing channel 21 in the processing state, thereby improving the dust removal effect of the first suction pipe 22. At the same time, after the bushing passes through the flexible sealing curtain 20 composed of slender plastic fibers, it fits against the pipe wall, so that the processing channel 21 forms a relatively closed space, thereby improving the dust removal effect.

[0038] like Figure 1 and Figure 7As shown, an external processing box 25 is mounted on the top of the base 1. A sealing door 26 is hinged to the front of the external processing box 25. The other end of the first suction pipe 22 passes through the external processing box 25 and is connected to an air pump 30. The other end of the air pump 30 is connected to an air purification device 31. The end of the first suction pipe 22 near the input end of the air pump 30 is connected to a second suction pipe 27. The other end of the second suction pipe 27 is connected to a control valve 28. The input end of the control valve 28 is connected to a dust collection box 29. The dust collection box 29 is fixedly installed inside the external processing box 25. It is used to treat the external ambient air of the processing channel 21. The air pump 30 transports the dust and metal particles generated in the processing channel 21 and the external treatment box 25 to the air purification device 31 through the first suction pipe 22, the second suction pipe 27 and the suction box 29. It should be noted that there are various air purification devices 31 on the market for air purification, and they need to be set according to actual needs. At the same time, the suction volume of the first and second suction pipes can be controlled by the control valve 28, which is convenient for actual setting.

[0039] The working principle of this invention: In actual processing, the automobile bushing to be ground is first placed on the outside of the two arc-shaped clamping plates 6. Then, the reciprocating screw 2 is started, driving the left and right sliding seats 3 to move towards or away from each other to a position matching the length of the bushing. The pneumatic clamping seat 4 is simultaneously positioned with the sliding seat 3. Then, the pneumatic gripper 5 is started, causing it to move horizontally outward, pushing the arc-shaped clamping plate 6 to open radially, simultaneously tightening the bushing from the inner walls at both ends, forming a double-end inner support rigid fixation. At this time, the bushing has been completely positioned in the center of the processing channel 21, and the flexible sealing curtain 20 automatically retracts outside the tube wall, forming a relatively closed space. Then, the drive motor 13 is started, driving the processing cover 8 to rotate as a whole through the drive wheel 12 and the first gear ring 11. Before the processing cover 8 rotates, if it is necessary to adapt to the current outer diameter of the bushing, the operator loosens the locking bolt 24 and rotates the drive shaft 23, so that one of the driven wheels 15 drives all the driven wheels 15 and the adjusting screw 1 through the second gear ring 14. 6. Rotation drives each mounting base 17 to move radially synchronously, allowing multiple grinding wheels 18 to be adjusted into position and locked again. At this point, all grinding wheels 18 are in contact with the outer wall of the bushing and maintain equal pressure. Subsequently, the first lead screw 10 of the transverse mechanism rotates under the drive of an external motor, driving the moving arm 9 and the mounting plate 7 to move horizontally and reciprocally along the base 1. During the combined rotation and transverse motion of the processing cover 8, the grinding wheels 18 continuously grind the outer wall of the bushing in both circumferential and axial directions. Metal chips and dust generated during the grinding process are promptly sucked into the dust collection box 29 by the air pump 30 through the first dust collection pipe 22 and the second dust collection pipe 27, and then discharged after being purified by the air purification device 31. The flexible sealing curtain 20 and the sealing cover 19 together maintain negative pressure in the channel to prevent leakage. When the outer surface of the entire bushing is ground, the pneumatic gripper 5 retracts, the arc-shaped clamp 6 is released, and the bushing can be lifted away, completing a fully automatic, high-precision, and low-pollution automotive parts grinding process.

[0040] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
