Description

Technical Field

[0001] The invention relates to the technical field of steel rim polishing, in particular to a smoothness processing device based on steel rim production. Background Art

[0002] The rim is a cylindrical metal component whose center is mounted on an axle and whose inner profile supports the tire. It is also called a wheel rim, wheel, or hub. It bears both axial and radial loads in the wheel. It is developed based on standard angular contact ball bearings and tapered roller bearings, integrating the two sets of bearings into one. It has the advantages of good assembly performance, the ability to omit clearance adjustment, and large load capacity. It has been widely used in cars and is also showing a trend of gradually expanding its application in heavy-duty trucks.

[0003] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. Polishing the surface of the steel ring can improve the smoothness of the steel ring surface and facilitate the subsequent use of the steel ring.

[0004] In the prior art, when grinding the steel rim, rollers are usually used to limit and fix the steel rim, and the steel rim is driven to rotate at a uniform speed by the rotating driving force of the roller. On this basis, the symmetrically arranged grinding wheels work together to achieve synchronous grinding of the inner and outer rings of the steel rim. However, in the actual grinding process, continuous grinding resistance is generated when the grinding wheel contacts the surface of the steel rim. This resistance is transmitted to the driving roller through the steel rim, forming a reverse torque. Since the friction force transmission between the steel rim and the roller has certain limitations, when the reverse torque exceeds the contact friction force threshold, it will cause the steel rim to slide slightly relative to the roller. This unstable motion state will not only cause deviations in the grinding trajectory and uneven surface roughness of the steel rim, but may also cause over-grinding or under-grinding in local areas, thereby adversely affecting the geometric accuracy and surface quality of the steel rim, and ultimately affecting the overall performance and service life of the product.

[0014] In summary, the present invention mainly has the following beneficial effects: 1. The present invention achieves a firm clamping and fixing of the steel ring through the clamping blocks in the three groups of clamping assemblies, and cooperates with the turntable to drive the clamping assembly to rotate as a whole, thereby driving the steel ring to rotate synchronously. In this process, the inner and outer rings of the steel ring are polished by the grinding wheel to improve the smoothness of the steel ring. During the clamping operation of the clamping blocks on the steel ring, two groups of clamping assemblies maintain a continuous clamping state on the steel ring. When the friction wheel in the remaining group of clamping assemblies contacts the friction block, the friction block cooperates with the bidirectional threaded rod to drive the two groups of moving blocks to move synchronously, releasing the clamping effect of the clamping blocks on the steel ring. Then, the T-shaped seat moves downward under the resistance of the arc block, thereby driving the clamping block to descend and separate from the steel ring. , so that the grinding wheel can grind the original clamping part of the steel ring and grind the steel ring in all directions. When the friction wheel is separated from the friction block, the friction wheel is reset under the joint action of the torsion spring and the damping shaft, driving the clamping block to slowly return to its position. When the oblique block is separated from the arc block, the T-shaped seat is reset under the elastic force of the spring. At this time, the clamping block resumes its clamping and limiting function on the steel ring, and the friction wheel of the next set of clamping components is about to contact the friction block, ensuring that there are always two sets of clamping components to maintain the clamping and limiting function on the steel ring during the grinding process, thereby preventing the steel ring from shifting during grinding and avoiding deviation in the grinding trajectory, thereby improving the grinding quality and effect of the steel ring to a certain extent. 2. The present invention can flexibly adjust the initial position of the clamping block on the inner wall of the cavity of the movable block through a screw, so as to achieve stable clamping of steel rings of different thicknesses and specifications, thereby improving the versatility of the device. When the diameter of the steel ring to be processed is large, the rotating block is manually rotated, and the arc groove opened on the surface of the rotating block cooperates with the limit groove opened on the surface of the fixed disk to drive the connecting rod to move on the inner wall of the limit groove, and then the initial positions of the three groups of clamping assemblies are adjusted at the same time, so that the device can adapt to the processing of steel rings of different sizes and widths. The overall flexibility is high and the adaptability range is wide. During the position adjustment process of the clamping assembly, the movable block is driven to move horizontally by the cylinder, so that the spatial position of the arc block and the friction block can be synchronously adjusted. At the same time, with the help of the sliding cooperation between the guide block and the guide groove, the posture of the arc block and the friction block is adaptively bent and corrected, so that the adjusted clamping assembly can still maintain precise contact with the arc block and the friction block.

[0017] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 understood as limiting the present invention.

[0018] The following describes an embodiment of the present invention based on its overall structure.

[0019] Smoothness processing device based on steel ring production, such as Figure 1 - Figure 7 As shown, it includes a base plate 1, the upper surface of the base plate 1 is fixedly connected to a mounting base 2, the inner wall of the mounting base 2 is fixedly installed with an electric telescopic rod, and the top of the electric telescopic rod is fixedly connected to a mounting plate 21. The electric telescopic rod drives the mounting plate 21 to move up and down, so as to adjust the height of the grinding wheel 22; 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 separately through the two sets of threaded rods, so as to facilitate adaptation to steel rings of different sizes. For example, a fixing ring 3 is fixedly connected to the upper surface of the base plate 1, and a transmission assembly is provided on the inner wall of the fixing ring 3. The transmission assembly includes a turntable 41 rotatably connected to the inner wall of the fixing ring 3, and three groups 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 assembly to rotate, the steel ring can be driven to rotate and grind it in conjunction with the grinding wheel 22.

[0020] See Figure 3 - Figure 5 The two sets of movable blocks 56 are driven by the two-way threaded rod 55 to move, so that the clamping block 57 is separated from the steel ring. When the friction wheel 551 and the friction block 63 are separated, the friction wheel 551 is completely reset, and the steel ring is clamped and limited again. For example, the outer wall of the bidirectional threaded rod 55 is threadedly connected to two groups of moving blocks 56, and the inner walls of the two groups of moving blocks 56 are slidably connected to clamping blocks 57. One side surface of the clamping blocks 57 is provided with anti-slip grooves, and the clamping blocks 57 can be used to limit and clamp the steel ring. The setting of the anti-slip grooves on the clamping blocks 57 can improve the fixing effect of the clamping blocks 57 on the steel ring to a certain extent. Exemplarily, the inner walls of the two groups of movable blocks 56 are rotatably connected to a screw 571 threadedly connected to the clamping block 57, and one end of the screw 571 extends to the outer wall of the movable block 56. When it is necessary to clamp steel rings of different sizes, the initial position of the clamping block 57 can be adjusted by rotating the screw 571, thereby facilitating the limiting and fixing of steel rings of different sizes.

[0021] 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. Three groups of limiting grooves 421 corresponding to the clamping components are opened on the surface of the fixed disk 42, and three groups of arc grooves 431 are opened on the surface of the rotating block 43. The upper surface of the T-shaped seat 51 is fixedly connected to the limiting rod 511 below the fixed block 54. The outer wall of the limiting rod 511 is sleeved with a connecting rod 52. The end of the connecting rod 52 away from the limiting rod 511 extends Extending to the inner walls 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 walls of the arc groove 431 and the limiting groove 421, when the rotating block 43 is rotated, the arc groove 431 and the limiting groove 421 can be cooperated with each other by the connecting rod 52 and the limiting rod 511 to push the T-shaped seat 51 to move, thereby facilitating the adjustment of the initial position of the clamping assembly and adapting to steel rings of different specifications and sizes.

[0022] For example, the upper surface of the fixed disk 42 is fixedly connected with multiple groups of card blocks, and the lower surface of the rotating block 43 is provided with multiple groups of card slots matching the card blocks. A motor is installed on the inner wall of the bottom plate 1, and the output end of the motor extends to the inner wall of the fixed ring 3 and is connected to the turntable 41. When the position adjustment of the clamping assembly is completed, the rotating block 43 stops rotating, and the card blocks are stuck into the inner wall of the card slot to limit the rotating block 43, thereby fixing the position of the clamping assembly. See Figure 6 and Figure 7 It can be seen that a driving assembly located on the inner wall of the fixed ring 3 is provided on one side of the turntable 41. The driving assembly includes a cylinder fixedly mounted 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. The two side surfaces of the top of the movable block 61 are respectively fixedly connected to the arc block 62 and the friction block 63. The movable block 61 is located below the arc block 62 and the friction block 63. The two side surfaces are fixedly connected to the relatively arranged guide rods 611. The arc block 62 and the friction block 63 are provided with through grooves on the surfaces. The two sets of guide rods 611 are inserted into the inner walls of the through grooves. When it is necessary to adapt to steel rings of different sizes, after the position of the clamping assembly is adjusted by the transmission assembly, the cylinder is started, and the cylinder pushes the movable block 61 to move. The movable block 61 drives the arc block 62 and the friction block 63 to move at the same time, so that after the clamping assembly adjusts its position, the clamping assembly can still contact and cooperate with the driving assembly. Exemplarily, the inner wall of the fixing ring 3 is fixedly connected to a second fixing plate 65 arranged parallel to the cylinder, and the inner wall of the fixing ring 3 is fixedly connected to a first fixing plate 64 arranged perpendicular to the cylinder on the side 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. The top end of the arc block 62 and the bottom end of the friction block 63 are fixedly connected to guide blocks that are sleeved on the inner wall of the guide groove 66. When the arc block 62 and the friction block 63 adjust their positions, the arc block 62 and the friction block 63 are deformed by the mutual cooperation between the guide block and the guide groove 66, so that the friction wheel 551 and the inclined block 53 can still be in precise contact with the arc block 62 and the friction block 63 after moving their positions.

[0023] See Figure 3 - Figure 5 It can be seen that the upper surface of the T-shaped seat 51 is fixedly connected to the side of the limit rod 511 away from the inclined block 53, the upper surface of the inclined block 53 is provided with an inclined surface a, and the lower surface of one end of the arc block 62 is provided with an inclined surface b, and the inclined surface a matches the inclined surface b. When the turntable 41 drives the T-shaped seat 51 to move, the inclined surface a on the inclined block 53 contacts the inclined surface b on the arc block 62. Under the extrusion 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 is convenient for the grinding wheel 22 to grind the blocked area of ​​the clamping block 57, thereby facilitating the complete grinding of the inner and outer rings of the steel ring.

[0024] See Figure 4 and Figure 5 It can be seen that a fixing rod 58 is inserted into the side of the bottom end of the T-shaped seat 51 near the limit 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 arrangement 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. Three groups of slide grooves 411 are provided on the upper surface of the turntable 41 , and the bottom end of the fixing rod 58 is slidably connected to the inner wall of the slide groove 411 . The setting of the slide groove 411 can limit the fixing rod 58 , making it easy for the fixing rod 58 to move parallel to the inner wall of the slide groove 411 .

[0025] The working principle of the present invention is as follows: when grinding a steel ring, the rotating block 43 is manually rotated, and the arc-shaped groove 431 formed on the surface of the rotating block 43 cooperates with the limiting groove 421 formed on the surface of the fixed plate 42 to drive the connecting rod 52 to move along the inner wall of the limiting groove 421. When the clamping block is engaged with the inner wall of the clamping groove, the position of the rotating block 43 can be fixed, thereby facilitating the synchronous adjustment of the positions of the three groups of clamping assemblies to adapt to steel rings of different sizes. The cylinder is started again, and the cylinder drives the movable block 61 to move, and 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, the arc block 62 and the friction block 63 are deformed when they move through the mutual cooperation between the guide block and the guide groove 66, and with the assistance of the guide rod 611, so 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; Then, the screw rod 571 is rotated to adjust the position of the clamping block 57 on the inner wall of the cavity of the moving block 56, and the steel ring is placed on the upper end of the moving block 56. The steel ring is then limited and clamped by the clamping block 57. After the clamping is completed, the height of the mounting plate 21 is adjusted by the electric telescopic rod, and the distance between the two sets of grinding wheels 22 is adjusted by cooperating with the adjustment component so that the two sets of grinding wheels 22 fit the bottom ends of the inner and outer rings of the steel ring. The turntable 41 is then driven by the motor to rotate, and the turntable 41 drives the three sets of clamping components to rotate simultaneously. The grinding wheel 22 is started, and the steel ring can be ground by the grinding wheel 22. During the grinding process, the friction wheel 551 in one of the three groups of clamping assemblies contacts the friction block 63 during the rotation process, and the friction wheel 551 is driven to rotate by the friction force between the friction block 63 and the friction wheel 551, thereby causing the friction wheel 551 to drive the bidirectional threaded rod 55 to rotate, and the bidirectional threaded rod 55 drives the two groups of moving blocks 56 to move at the same time, so that the clamping block 57 cancels the clamping limit on the steel ring. When the friction wheel 551 is separated from the friction block 63, the inclined block 53 just contacts the arc block 62. When the inclined surface a is fitted with the inclined surface b, since the arc block 62 is at a fixed height, when the clamping assembly rotates, the arc block 62 squeezes the inclined block 53, which can drive the T-shaped seat 51 and the fixed block 54 to move downward, separating the clamping block 57 from the steel ring, so that the grinding wheel 22 The steel ring clamping part is polished. When the inclined block 53 is separated from the arc block 62, the T-shaped seat 51 is reset under the elastic action of the spring 581, driving the fixed block 54 to move upward, so that the top of the movable block 56 contacts the bottom end 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 re-clamp the steel ring. At this time, under the rotation of the turntable 41, the friction wheel 551 in the next group of clamping assemblies is about to contact the friction block 63, thereby ensuring that there are always two groups of clamping assemblies to maintain the clamping limit of the steel ring during the polishing process, preventing the steel ring from displacing during polishing, and significantly improving the polishing quality and effect of the steel ring to a certain extent.
