Description

Technical Field

[0001] This invention relates to the field of steel ring polishing technology, specifically to a smoothness treatment device based on steel ring production. Background Technology

[0002] A steel rim is a cylindrical metal component that supports the tire and is centrally mounted on the axle. It is also called a wheel rim, wheel hub, or wheel rim. In a wheel, it bears both axial and radial loads. It was developed based on standard angular contact ball bearings and tapered roller bearings, integrating the two sets of bearings into one unit. It has advantages such as good assembly performance, no need for clearance adjustment, and large load capacity. It is widely used in passenger cars and is gradually expanding its application in heavy-duty trucks.

[0003] Polishing is a processing method that uses mechanical, chemical, or electrochemical processes to reduce the surface roughness of a workpiece in order to obtain a bright and smooth surface. Polishing the surface of a steel ring can improve the smoothness of the steel ring surface, making it easier for the steel ring to be used in the future.

[0004] In existing technologies, when grinding steel rings, rollers are typically used to limit and fix the steel ring, while the rotational driving force of the rollers drives the steel ring to rotate at a constant speed. Based on this, symmetrically arranged grinding wheels work together to achieve synchronous grinding of the inner and outer rings of the steel ring. However, in the actual grinding process, continuous grinding resistance is generated when the grinding wheels contact the surface of the steel ring. This resistance is transmitted through the steel ring to the driving roller, forming a reverse torque. Since the frictional force transmission between the steel ring and the roller has certain limitations, when the reverse torque exceeds the contact friction threshold, it will cause a slight slippage of the steel ring relative to the roller. This unstable motion state not only causes deviations in the grinding trajectory and uneven surface roughness of the steel ring, but may also cause over-grinding or under-grinding in local areas, thus adversely affecting the geometric accuracy and surface quality of the steel ring, ultimately affecting the overall performance and service life of the product.

[0009] Preferably, the drive assembly includes a cylinder fixedly installed on the outer wall of the fixed ring, with the cylinder output end extending to the inner wall of the fixed ring and fixedly connected to a movable block. An arc-shaped block and a friction block are fixedly connected to the top two sides of the movable block, respectively. Guide rods are fixedly connected to the two sides of the movable block below the arc-shaped block and the friction block. A through groove is opened on the surface of both the arc-shaped block and the friction block, and both sets of guide rods are inserted into the inner wall of the through groove.

[0010] Preferably, one end of the bidirectional threaded rod extends to the outer wall of the fixed block and is connected to a friction wheel via a torsion spring. The friction wheel contacts the upper surface of the friction block during rotation. An inclined block is fixedly connected to the side of the upper surface of the T-shaped seat away from the limiting rod. An inclined surface a is provided on the upper surface of the inclined block, and an inclined surface b is provided on the lower surface of one end of the arc-shaped block.

[0013] Preferably, the upper surface of the fixed plate is fixedly connected with multiple sets of locking blocks, the lower surface of the rotating block is provided with multiple sets of locking slots that match the locking blocks, the inner wall of the base plate is equipped with a motor, and the output end of the motor extends to the inner wall of the fixed ring and connects with the turntable.

[0014] In summary, the present invention has the following main beneficial effects:

[0015] 1. This invention achieves stable clamping and fixing of the steel ring through clamping blocks in three sets of clamping components. The turntable drives the entire clamping component to rotate, thereby causing the steel ring to rotate synchronously. During this process, a grinding wheel polishes the inner and outer rings of the steel ring, improving its smoothness. In the clamping operation, two sets of clamping components maintain continuous clamping of the steel ring. When the friction wheel in the remaining clamping component contacts the friction block, the friction block, in conjunction with the bidirectional threaded rod, drives the two sets of moving blocks to move synchronously, releasing the clamping effect on the steel ring. Then, the T-shaped seat moves downwards under the resistance of the arc-shaped block, causing the clamping block to descend and separate from the steel ring. This allows the grinding wheel to grind the original clamping area of ​​the steel ring, performing all-round grinding. When the friction wheel separates from the friction block, the friction wheel resets under the combined action of the torsion spring and the damping shaft, causing the clamping block to slowly return to its original position. When the inclined block separates from the arc block, the T-shaped seat resets under the elastic force of the spring. At this time, the clamping block resumes its clamping and limiting function for the steel ring, and the friction wheel of the next set of clamping components is just about to contact the friction block. This ensures that there are always two sets of clamping components that maintain clamping and limiting the steel ring during the grinding process, thereby preventing the steel ring from shifting during grinding and avoiding deviations in the grinding trajectory. This improves the grinding quality and effect of the steel ring to a certain extent.

[0016] 2. This invention allows for flexible adjustment of the initial position of the clamping block within the cavity of the moving block via a screw, thereby achieving stable clamping of steel rings of different thicknesses and improving the versatility of the device. When the diameter of the steel ring to be processed is large, the rotating block can be manually rotated. The interaction between the arc-shaped groove on the surface of the rotating block and the limiting groove on the surface of the fixed plate drives the connecting rod to move within the limiting groove, thereby simultaneously adjusting the initial positions of the three clamping components. This allows the device to adapt to the processing of steel rings of different widths, exhibiting high overall flexibility and a wide range of applicability. During the adjustment of the clamping component positions, the moving block can be translated by a cylinder, simultaneously adjusting the spatial positions of the arc-shaped block and the friction block. At the same time, the sliding cooperation between the guide block and the guide groove allows for adaptive bending correction of the posture of the arc-shaped block and the friction block, ensuring that the adjusted clamping components still maintain precise contact with the arc-shaped block and the friction block.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The embodiments of the present invention will now be described.

[0027] Smoothing treatment devices based on steel ring production, such as Figure 1 - Figure 7 As shown, it includes a base plate 1, a mounting base 2 is fixedly connected to the upper surface of the base plate 1, an electric telescopic rod is fixedly installed on the inner wall of the mounting base 2, and a mounting plate 21 is fixedly connected to the top of the electric telescopic rod. The height of the grinding wheel 22 can be adjusted by raising and lowering the mounting plate 21 through the electric telescopic rod.

[0028] For example, two sets of grinding wheels 22 for grinding the inner and outer rings of the steel ring are movably mounted on the lower surface of the mounting plate 21. The two sets of grinding wheels 22 are connected to the mounting plate 21 through an adjustment assembly. The adjustment assembly includes two sets of threaded rods. The positions of the two sets of grinding wheels 22 can be adjusted by the two sets of threaded rods, so as to adapt to steel rings of different sizes.

[0029] For example, a fixed ring 3 is fixedly connected to the upper surface of the base plate 1. A transmission assembly is provided on the inner wall of the fixed ring 3. The transmission assembly includes a turntable 41 rotatably connected to the inner wall of the fixed ring 3. Three sets of clamping assemblies for clamping the steel ring are slidably connected to the upper surface of the turntable 41. By driving the turntable 41 to drive the clamping assemblies to rotate, the steel ring can be driven to rotate and be polished in conjunction with the grinding wheel 22.

[0030] See Figure 3 - Figure 5 It is known that the clamping assembly includes a T-shaped seat 51, a fixed block 54 is fixedly connected to the top of the T-shaped seat 51, and a bidirectional threaded rod 55 is rotatably connected to the inner wall of the fixed block 54 through a damping shaft. One end of the bidirectional threaded rod 55 extends to the outer wall of the fixed block 54 and is connected to a friction wheel 551 through a torsion spring. During the rotation of the friction wheel 551, it contacts the upper surface of the friction block 63. When the clamping assembly rotates, the friction generated by the friction wheel 551 contacting the friction block 63 drives the bidirectional threaded rod 55 to rotate. The bidirectional threaded rod 55 can then drive the two sets of moving blocks 56 to move, causing the clamping block 57 to separate from the steel ring. When the friction wheel 551 separates from the friction block 63, the friction wheel 551 resets under the action of the torsion spring. By setting the damping shaft, the friction wheel 551 has a certain resistance when rotating, which slows down the reset time of the friction wheel 551. When the inclined block 53 on the T-shaped seat 51 separates from the arc block 62, the friction wheel 551 is just fully reset, and the steel ring is clamped and limited again.

[0031] For example, the outer wall of the bidirectional threaded rod 55 is threaded with two sets of moving blocks 56, and the inner walls of the two sets of moving blocks 56 are slidably connected with clamping blocks 57. One side surface of the clamping block 57 is provided with anti-slip texture. The steel ring can be limited and clamped by the clamping block 57. The anti-slip texture on the clamping block 57 can improve the fixing effect of the clamping block 57 on the steel ring to a certain extent.

[0032] For example, the inner walls of both sets of movable blocks 56 are rotatably connected with screws 571 that are threadedly connected to clamping blocks 57. One end of the screws 571 extends to the outer wall of the movable blocks 56. When it is necessary to clamp steel rings of different sizes, the initial position of clamping blocks 57 can be adjusted by rotating the screws 571, thereby facilitating the limiting and fixing of steel rings of different sizes.

[0033] See Figure 3 - Figure 5 It can be seen that a fixed disk 42 is fixedly connected to the center of the upper surface of the turntable 41, and a rotating block 43 is rotatably connected to the upper surface of the fixed disk 42. The surface of the fixed disk 42 has three sets of limiting grooves 421 corresponding to the clamping components, and the surface of the rotating block 43 has three sets of arc-shaped grooves 431. A limiting rod 511 is fixedly connected to the upper surface of the T-shaped seat 51 below the fixed block 54. A connecting rod 52 is sleeved on the outer wall of the limiting rod 511, and the end of the connecting rod 52 away from the limiting rod 511 extends... Extending to the inner wall of the arc groove 431 and the limiting groove 421, when it is necessary to adjust the initial position of the clamping assembly, since the fixed plate 42 is fixed and one end of the connecting rod 52 is sleeved on the inner wall of the arc groove 431 and the limiting groove 421, when the rotating block 43 is rotated, the T-shaped seat 51 can be pushed to move through the cooperation of the connecting rod 52 and the limiting rod 511 under the mutual cooperation of the arc groove 431 and the limiting groove 421, thereby facilitating the adjustment of the initial position of the clamping assembly and adapting to steel rings of different specifications and sizes.

[0034] For example, multiple sets of locking blocks are fixedly connected to the upper surface of the fixed disk 42, and multiple sets of locking slots matching the locking blocks are opened on the lower surface of the rotating block 43. A motor is installed on the inner wall of the base plate 1, and the output end of the motor extends to the inner wall of the fixed ring 3 and connects to the turntable 41. After the position of the clamping component is adjusted, the rotating block 43 stops rotating, and the locking blocks are inserted into the inner wall of the locking slots, which limits the position of the rotating block 43 and fixes the position of the clamping component.

[0035] See Figure 6 and Figure 7It is known that a drive assembly is provided on one side of the turntable 41, located on the inner wall of the fixed ring 3. The drive assembly includes a cylinder fixedly installed on the outer wall of the fixed ring 3, and the output end of the cylinder extends to the inner wall of the fixed ring 3 and is fixedly connected to a movable block 61. An arc-shaped block 62 and a friction block 63 are fixedly connected to the two sides of the top of the movable block 61, respectively. Guide rods 611 are fixedly connected to the two sides of the movable block 61 below the arc-shaped block 62 and the friction block 63. The surfaces of the arc-shaped block 62 and the friction block 63 are both provided with through grooves. The two sets of guide rods 611 are inserted into the inner wall of the through grooves. When it is necessary to adapt to steel rings of different sizes, after adjusting the position of the clamping assembly through the transmission assembly, the cylinder is started. The cylinder pushes the movable block 61 to move. The movable block 61 drives the arc-shaped block 62 and the friction block 63 to move simultaneously, so that after the position of the clamping assembly is adjusted, the clamping assembly can still contact and cooperate with the drive assembly.

[0036] For example, a second fixing plate 65 parallel to the cylinder is fixedly connected to the inner wall of the fixing ring 3, and a first fixing plate 64 perpendicular to the cylinder is fixedly connected to the side of the inner wall of the fixing ring 3 away from the second fixing plate 65. Guide grooves 66 are provided on the surfaces of the first fixing plate 64 and the second fixing plate 65. Guide blocks sleeved on the inner wall of the guide grooves 66 are fixedly connected to the top of the arc-shaped block 62 and the bottom of the friction block 63. When the arc-shaped block 62 and the friction block 63 are adjusted, the arc-shaped block 62 and the friction block 63 are deformed by the mutual cooperation of the guide blocks and the guide grooves 66, so that the friction wheel 551 and the inclined block 53 can still make precise contact with the arc-shaped block 62 and the friction block 63 after the position is moved.

[0037] See Figure 3 - Figure 5 It is known that a wedge block 53 is fixedly connected to the side of the upper surface of the T-shaped seat 51 away from the limit rod 511. The upper surface of the wedge block 53 is provided with a wedge a, and the lower surface of one end of the arc block 62 is provided with a wedge b. The wedge a and the wedge b match. When the turntable 41 drives the T-shaped seat 51 to move, the wedge a on the wedge block 53 contacts the wedge b on the arc block 62. Under the pressure of the arc block 62, the T-shaped seat 51 can be driven to move downward, so that the clamping block 57 is separated from the steel ring, which makes it easier for the grinding wheel 22 to grind the part covered by the clamping block 57, thereby making it easier to grind the inner and outer rings of the steel ring completely.

[0038] See Figure 4 and Figure 5 It can be seen that a fixing rod 58 is inserted at the bottom end of the T-shaped seat 51 near the limiting rod 511. A spring 581 is sleeved on the outer wall of the fixing rod 58. The bottom end of the spring 581 is fixedly connected to the fixing rod 58, and the top end of the spring 581 is fixedly connected to the bottom end of the T-shaped seat 51. The setting of the spring 581 can drive the T-shaped seat 51 to reset after the arc block 62 and the inclined block 53 are separated.

[0039] The upper surface of the turntable 41 is provided with three sets of sliding grooves 411. The bottom end of the fixing rod 58 is slidably connected to the inner wall of the sliding groove 411. The setting of the sliding groove 411 can limit the fixing rod 58, so that the fixing rod 58 can move parallel to the inner wall of the sliding groove 411.

[0040] The working principle of this invention is as follows: When grinding the steel ring, the rotating block 43 is manually rotated. The arc groove 431 on the surface of the rotating block 43 and the limiting groove 421 on the surface of the fixed plate 42 cooperate with each other to drive the connecting rod 52 to move in the inner wall of the limiting groove 421. When the locking block is locked into the inner wall of the locking groove, the position of the rotating block 43 can be fixed, thereby facilitating the synchronous adjustment of the position of the three sets of clamping components to adapt to steel rings of different sizes.

[0041] When the cylinder is restarted, the cylinder drives the movable block 61 to move. The movable block 61 drives the arc block 62 and the friction block 63 to move simultaneously. Since the positions of the first fixed plate 64 and the second fixed plate 65 are fixed, when the arc block 62 and the friction block 63 move, they deform due to the cooperation between the guide block and the guide groove 66 and the assistance of the guide rod 611. This ensures that the friction wheel 551 and the inclined block 53 are still in precise contact with the arc block 62 and the friction block 63 after the position is adjusted.

[0042] Then rotate screw 571 to adjust the position of clamping block 57 on the inner wall of cavity of moving block 56, place steel ring on the upper end of moving block 56, and then clamp steel ring by clamping block 57. After clamping, adjust the height of mounting plate 21 by electric telescopic rod, and at the same time adjust the distance between two sets of grinding wheels 22 with adjustment component so that the two sets of grinding wheels 22 are in contact with the bottom of inner and outer ring of steel ring. Then drive turntable 41 to rotate by motor, turntable 41 drives three sets of clamping components to rotate at the same time, start grinding wheel 22, and then grind steel ring by grinding wheel 22.

[0043] During the grinding process, the friction wheel 551 in one of the three clamping assemblies contacts the friction block 63 during rotation. The friction between the friction block 63 and the friction wheel 551 drives the friction wheel 551 to rotate, which in turn drives the bidirectional threaded rod 55 to rotate. The bidirectional threaded rod 55 drives the two sets of moving blocks 56 to move simultaneously, causing the clamping block 57 to release its clamping limit on the steel ring. When the friction wheel 551 separates from the friction block 63, the inclined block 53 just comes into contact with the arc-shaped block 62. When the inclined surface a and the inclined surface b are in contact, since the height of the arc-shaped block 62 is fixed, when the clamping assembly rotates, the pressure of the arc-shaped block 62 on the inclined block 53 causes the T-shaped seat 51 and the fixed block 54 to move downward, separating the clamping block 57 from the steel ring, allowing the grinding wheel 22 to move freely. The steel ring clamping area is polished. After the inclined block 53 separates from the arc block 62, the T-shaped seat 51 resets under the elastic action of the spring 581, driving the fixed block 54 to move upward, so that the top of the moving block 56 contacts the bottom of the steel ring. At this time, the friction wheel 551, under the action of the torsion spring and the damping bearing, just drives the bidirectional threaded rod 55 to reset, and clamps the steel ring again. At this time, under the rotation of the turntable 41, the friction wheel 551 in the next set of clamping components will contact the friction block 63, thereby ensuring that there are always two sets of clamping components to keep the steel ring clamped and limited during the polishing process, preventing the steel ring from shifting during polishing, and significantly improving the polishing quality and effect of the steel ring to a certain extent.
