Description

Technical Field

[0001] The invention belongs to the field of wheel hub production and polishing, and in particular relates to a polishing device for automobile wheel hub production. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and flat surface. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of a workpiece, but is intended to obtain a smooth surface or mirror gloss, and is sometimes used to eliminate gloss.

[0003] There are usually multiple spokes on the wheel hub, and a fan-shaped area is formed between the spokes. Due to the different numbers of spokes, the angles of the fan-shaped areas are different. The more spokes there are, the smaller the angle of the fan-shaped area is, and a thinner polishing rod is required. Conversely, the fewer spokes there are, the larger the angle of the fan-shaped area is, and a thicker polishing rod is required. Therefore, polishing rods of different sizes are required to correspond to the angles between different spokes, which will not lead to waste of polishing rods. At the same time, it is necessary to constantly replace the polishing rods on the polishing equipment, thereby reducing the efficiency of existing polishing equipment in polishing spokes between hubs of different sizes.

Due to the different numbers of spokes, the angles of the fan-shaped areas are different. When the number of spokes is greater, the angle of the fan-shaped area is smaller, and a thinner polishing rod is required. On the contrary, when the number of spokes is smaller, the angle of the fan-shaped area is larger, and a thicker polishing rod is required. Therefore, polishing rods of different sizes are required to correspond to the angles between different spokes, which will not cause waste of polishing rods. At the same time, it is necessary to continuously replace the polishing rods on the polishing device, thereby reducing the efficiency of the existing polishing equipment in polishing the spokes between wheel hubs of different sizes.

[0016] Technical effects and advantages of the present invention: Compared with the prior art, the polishing equipment for automobile wheel hub production proposed by the present invention has the following advantages:

[0017] 1. The present invention polishes the fan-shaped angle A on the hub by setting an adjustable polishing assembly. When polishing hubs with different numbers of spokes, the adjustable polishing assembly can be appropriately adjusted to adapt to angles of different sizes. There is no need to replace the polishing assembly. The adjustable polishing assembly can replace a series of polishing rods of different specifications through adjustment, and there is no need to replace it, which is conducive to saving time and improving polishing efficiency.

[0018] 2. The present invention sets an electric push rod. In the process of adjusting the polishing component from the angle A to the inner arc surface B, the electric push rod pushes the arc plate to increase the distance between the arc plate and the vertical rod, so that the polishing plate contacts the side surfaces of the two spokes and performs rotational polishing to adapt to the increasing distance between the two hub spokes in the process from the angle A to the inner arc surface B. Compared with manual polishing, most of the manual polishing uses a polishing rod to stick to the side of the spoke and move for polishing, and the side surfaces of the two spokes need to be polished separately. The present device only needs to push the adjusted polishing component from the angle A to the position of the inner arc surface B, which is faster.

[0019] 3. The present invention provides a hinge seat on one side of the arc plate. When the adjustment polishing assembly moves to the inner arc surface B of the hub, the electric push rods on both sides extend to push the polishing plate to squeeze the spoke side point C, so that the adjustment polishing assembly is approximately elliptical. When the electric push rod moves the polishing plate to polish the inner arc surface B, the friction increases due to the squeezing of the polishing plate at point N, so that when the electric push rod moves the arc plate, the arc plate and the electric push rod rotate, so that the other end of the polishing plate is squeezed on the spoke side during rotation. As the arc plate continues to move, the position where the other end of the polishing plate is squeezed on the spoke side during rotation gradually changes and moves toward the inner arc surface B. When moving, the other end of the polishing plate polishes the angle F between the spoke and the inner arc surface B of the hub, and polishes the dead angle. After one rotation, the driving motor drives the adjustment polishing assembly to reverse and polish the angle on the other side to avoid omissions and make the polishing more comprehensive.

The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention provides Figure 1-8 The polishing equipment for automobile wheel hub production shown in the figure includes a workbench 1, the upper surface of the workbench 1 is fixedly connected to a vertical plate 11, one side of the vertical plate 11 is provided with a first slide groove, a slider 13 is slidably connected in the first slide groove, the upper surface of the vertical plate 11 is fixedly connected to a telescopic member 14, the telescopic member 14 is a cylinder or a hydraulic cylinder, the telescopic rod of the telescopic member 14 is fixedly connected to the slider 13, one side of the slider 13 is fixedly connected to a transverse plate 15, the transverse plate 15 is provided with an adjusting polishing assembly 2, the adjusting polishing assembly 2 is used for polishing wheel hub spokes with different angles, and the upper surface of the workbench 1 is provided with a rotating clamping device 4, the rotating clamping device 4 is used for clamping the wheel hub.

[0030] This device is used to polish the spokes 10 of the wheel hub. When polishing the angle A of the fan-shaped area E formed by two spokes 10, the staff puts the wheel hub on the workbench 1, so that the spokes 10 on the wheel hub 100 face upward, rotates the clamping device 4 to clamp the wheel hub 100, fixes the wheel hub 100 on the rotating clamping device 4, and the telescopic member 14 pushes the cross plate 15 downward, so that the adjustment polishing assembly 2 on the cross plate 15 is inserted downward into the fan-shaped area E on the wheel hub 100, as shown in FIG. Figure 2, adjust the polishing assembly 2 to polish the fan-shaped angle A on the wheel hub 100. After polishing is completed, the telescopic member 14 pulls the cross plate 15 upward through the telescopic rod, and the cross plate 15 drives the adjustment polishing assembly 2 upward and leaves the wheel hub 100 between the spokes 10; when it is necessary to polish the wheel hub 100 with different numbers of spokes 10, the telescopic member 14 pushes the cross plate 15 downward, so that the adjustment polishing assembly 2 on the cross plate 15 is inserted downward into the fan-shaped area E on the wheel hub 100, and the adjustment polishing assembly 2 can be appropriately adjusted to adapt to the angle between the spokes 10 on the wheel hub 100, and the angle of the wheel hub 10 is adjusted. After polishing, the telescopic member 14 pulls the horizontal plate 15 upwards through the telescopic rod, and the horizontal plate 15 drives the adjustment polishing assembly 2 upwards and leaves between the spokes 10 of the wheel hub 100. The adjustment polishing assembly 2 is adjusted to restore to its original state, and then the clamping device 4 is rotated to clamp the wheel hub 100 and rotate it to a certain angle, so that the next sector-shaped area above the wheel hub 100 is rotated to the bottom of the adjustment polishing assembly 2, and the above process is repeated to polish the sector-shaped area, and then the clamping device 4 is repeatedly rotated to continuously rotate the unpolished sector-shaped area to the bottom of the adjustment polishing assembly 2 for polishing until all the sector-shaped areas are polished;

[0031] In the prior art, when polishing wheel hubs 100 of different sizes or the angles of different numbers of spokes 10, the operator needs to replace polishing heads of different sizes, which is time-consuming. However, the present device is provided with an adjustable polishing assembly 2, which can be appropriately adjusted to adapt to the angles between the spokes 10 on the wheel hub 100. The adjustable polishing assembly 2 can replace a series of polishing rods of different specifications through adjustment, and no replacement is required, which is conducive to saving time and improving polishing efficiency.

[0032] A square through groove is provided on the surface of the horizontal plate 15, and a moving seat 16 is slidably provided on the upper surface of the horizontal plate 15. The lower end of the moving seat 16 is slidably provided in the square through groove. The upper surface of the horizontal plate 15 is fixedly connected to the cylinder 17, and the telescopic rod of the cylinder 17 is fixedly connected to the moving seat 16. The upper surface of the moving seat 16 is fixedly connected to the driving motor 18, and the main shaft of the driving motor 18 passes through the moving seat 16. The adjusting and polishing assembly 2 is installed on the main shaft of the driving motor 18.

[0033] The telescopic member 14 pushes the cross plate 15 downward, so that the adjustment polishing assembly 2 on the cross plate 15 is inserted downward into the position A in the sector area E on the wheel hub 100. When the adjustment polishing assembly 2 polishes the angle A of the sector area E, the drive motor 18 drives the adjustment polishing assembly 2 to rotate through the main shaft for polishing. When the polishing at the angle A is completed, the oil cylinder 17 drives the moving seat 16 to move, and the moving seat 16 drives the drive motor 18 to move from the angle A of the sector area E to the inner arc surface B of the wheel hub 100. The drive motor 18 drives the adjustment polishing assembly 2 installed on the main shaft of the drive motor 18 to move from the angle A of the sector area E to the inner arc surface B of the wheel hub 100, as shown in FIG. Figure 7During the movement, the driving motor 18 drives the adjusting and polishing assembly 2 to maintain a rotating state, and the adjusting and polishing assembly 2 rotates to polish the side surfaces of the spokes 10 of the wheel hub 100. During the movement of the adjusting and polishing assembly 2 from the angle A to the inner arc surface B, the adjusting and polishing assembly 2 is continuously adjusted to become larger, so that the adjusting and polishing assembly 2 always keeps in contact with the side surfaces of the two spokes 10, and the adjusting and polishing assembly 2 rotates to polish the side surfaces of the two spokes 10 to adapt to the increasing distance between the spokes 10 of the two wheel hubs 100 from the angle A to the inner arc surface B. When the adjusting and polishing assembly 2 rotates from the angle A to the inner arc surface B, the distance between the spokes 10 of the two wheel hubs 100 increases. After the polishing is moved to the inner arc surface B, the telescopic member 14 pulls the horizontal plate 15 upward through the telescopic rod, and the horizontal plate 15 drives the adjustment polishing assembly 2 upward to leave between the spokes 10 of the wheel hub 100. After leaving between the spokes 10 of the wheel hub 100, the adjustment polishing assembly 2 is adjusted again to restore the initial state, and the wheel hub 100 is clamped by the clamping device 4 and rotated at a certain angle, so that the next sector-shaped area above the wheel hub 100 is rotated to the bottom of the adjustment polishing assembly 2, and the above process is repeated to polish the sector-shaped area, and the wheel hub 100 is clamped by the clamping device 4 and rotated at a certain angle until all the sector-shaped areas are polished;

[0034] Compared with manual polishing, most of the time, a polishing rod is used to move along the side of the spoke 10 for polishing, and the sides of the two spokes 10 need to be polished separately. The present device only needs to push the adjustment polishing assembly 2 from the angle A to the position of the inner arc surface B, which is faster.

[0035] The adjustment polishing assembly 2 includes a vertical rod 21, which is fixedly connected to the main shaft of the driving motor 18. A plurality of adjustment parts 3 are provided on the outer side of the vertical rod 21. A curved plate 22 is provided on one side of the plurality of adjustment parts 3. A polishing plate 23 is fixedly connected to one side of the plurality of curved plates 22. The adjustment part 3 is used to adjust the distance between the polishing plate 23 and the vertical rod 21. The curved plate 22 is made of rubber and has a certain elasticity. The plurality of curved plates 22 are arranged in a circular ring around the vertical rod 21, and a folded polishing cloth 24 is fixedly connected between two adjacent curved plates 22.

[0036] The number of adjusting members 3 on the outside of the vertical rod 21 can be determined according to the situation. Four are taken as an example in this paper. The four arc-shaped plates 22 are on the same axis and form an approximate circle. The telescopic member 14 pushes the horizontal plate 15 downward, so that the adjusting polishing assembly 2 on the horizontal plate 15 is inserted downward into the point A in the fan-shaped area E on the wheel hub 100. The adjusting member 3 adjusts the distance between the polishing plate 23 and the vertical rod 21, so that the polishing plate 23 is closely attached to the side of the spoke 10 at point A, and point A is polished. During polishing, the driving motor 18 drives the vertical rod 21 to rotate, and the vertical rod 21 drives the adjusting member 3 and the arc-shaped plate 22 and the polishing plate 23 fixed on the outer arc surface of the arc-shaped plate 22 to rotate, and the polishing plate 23 rotates to polish the fan-shaped area E on the wheel hub 100;

[0037] After the polishing of point A is completed, the oil cylinder 17 pushes the moving seat 16 to move, and the moving seat 16 drives the polishing plate 23 to move from the angle A of the fan-shaped area E to the inner arc surface B of the wheel hub 100 through the driving motor 18. In the process of the polishing plate 23 moving from the angle A to the inner arc surface B, the driving motor 18 always rotates the polishing plate 23 fixed on the outer arc surface of the arc plate 22 through the vertical rod 21, the adjusting member 3 and the arc plate 22. At the same time, the adjusting member 3 continuously pushes the arc plate 22 away from the vertical rod 21, so that the radius of the circle formed by the four arc plates 22 is continuously increased, and keeps in contact with the side surfaces of the two spokes 10, and the polishing assembly 2 is adjusted to rotate and polish the two spokes. The side of the strip 10 is adapted to the increasing distance between the spokes 10 of the two hubs 100 from the angle A to the inner arc surface B. The folded polishing cloth 24 can connect the arc plates 22 to reduce the dust entering between the arc plates 22 and the vertical rods 21 during polishing. The distance between the vertical rods 21 and the arc plates 22 is adjusted by the adjusting member 3, and the radius of the circle formed by the four arc plates 22 is adjusted. When polishing a large-sized hub, the radius of the circle formed by the four arc plates 22 is adjusted to be larger for polishing, so that the device can polish hubs of different specifications, expand the use range of the device, and make the device more flexible. The adjusting member 3 includes an electric push rod 31, which is fixedly connected to the vertical rod 21. The inner arc surface of the arc plate 22 is provided with a mounting groove, and a hinge seat 32 is slidably connected in the mounting groove. The hinge seat 32 and the side wall of the mounting groove are fixedly connected to a first spring 33. The telescopic rod of the electric push rod 31 is hinged to the hinge seat 32, and a torsion spring is provided at the hinge. A plurality of separation grooves 34 are provided on the polishing plate 23. When the adjusting member 3 adjusts the radius of the circle formed by the four arc plates 22, the electric push rod 31 simultaneously pushes the arc plates 22 to move, changes the distance between the arc plates 22 and the vertical rod 21, so that the polishing plate 23 is always attached to the side of the spoke 100, and the first spring 33 plays a buffering role to prevent the electric push rod 31 from pushing too much, causing the polishing plate 23 to be squeezed on the side of the spoke and unable to move for polishing. The electric push rod 31 is used in conjunction with the controller, which is a prior art and will not be described in detail here; when the polishing assembly 2 is adjusted to move to the inner arc surface B of the wheel hub, one of the polishing plates 23 contacts the inner arc surface B such as Figure 7 At point D, the electric push rods 31 on both sides extend to push the polishing plate 23 to squeeze the side of the spoke 10. Figure 7 The polishing assembly 2 is shaped approximately elliptical. When the driving motor 18 drives the polishing assembly 2 to rotate and polish, the polishing plate 23 in contact with point C rotates toward point D, and the corresponding electric push rod 31 contracts. When one end of the polishing plate 23 is pressed against the inner arc surface B, as shown in FIG. Figure 8 Middle N point;

[0038] When the driving motor 18 drives the adjustment polishing assembly 2 to rotate and polish, and the electric push rod 31 moves the polishing plate 23 to polish the inner arc surface B, the friction increases due to the extrusion of the polishing plate 23 at point N, and there is resistance to block the arc plate 22 from moving forward, so that when the electric push rod 31 moves the arc plate 22, the arc plate 22 and the electric push rod 31 rotate, so that the other end of the polishing plate 23 is pressed against the side of the spoke 10 during the rotation, and the arc plate 22 is slightly deformed at this time, and the polishing plate 23 is deformed toward the angle F, so that the separation groove 34 becomes larger, as shown in FIG. Figure 8 At point M, as the arc plate 22 continues to move, the position M where the other end of the polishing plate 23 is squeezed on the side of the spoke during rotation gradually changes and moves toward the inner arc surface B. The polishing plate 23 grinds the hub during movement. When the other end of the polishing plate 23 slides over the angle F, the other end of the polishing plate 23 polishes the angle F between the spoke 10 and the inner arc surface B of the hub and polishes the dead angle. After one rotation, the driving motor 18 drives the adjustment polishing assembly 2 to reverse and polish the angle on the other side to avoid omissions and make the polishing more comprehensive.

[0039] The rotating clamping device 4 includes a rotating seat 41, a rotating cavity is opened on the workbench 1, and the rotating seat 41 is rotatably arranged in the rotating cavity through a bearing, two second sliding grooves are provided on the upper surface of the rotating seat 41, and sliding rods 42 are slidably connected in the two second sliding grooves, and two hydraulic cylinders 44 are fixedly connected to the upper surface of the rotating seat 41, and the telescopic rods of the two hydraulic cylinders 44 are respectively fixedly connected to the two sliding rods 42, and one side of the sliding rod 42 is fixedly connected to an arc-shaped extrusion block 43, and the arc-shaped extrusion block 43 is elastic. The lower end surface of the rotating seat 41 is located below the workbench 1, and a gear ring 45 is fixedly connected to the outer ring surface of the lower end of the rotating seat 41. A second motor 46 is fixedly connected to the workbench 1, and the main shaft of the second motor 46 is fixedly connected to a gear 47, and the gear 47 is meshed with the gear ring 45.

[0040] The two hydraulic cylinders 44 pull the two sliding rods 42 to slide in the two second sliding grooves, and at the same time, the two sliding rods 42 approach each other, and the wheel hub 100 is placed on the rotating seat 41. At this time, the two sliding rods 42 are located in the wheel hub 100, and the two hydraulic cylinders 44 push the two sliding rods 42 to slide toward the inner arc surface of the wheel hub 100 until the arc extrusion block 43 squeezes the inner arc surface B of the wheel hub 100 to fix the wheel hub 100. A shape recognition sensor is provided on the lower surface of the cross plate 15. This is a prior art and will not be described in detail here. The second motor 46 drives the rotating seat 41 to rotate through the gear 47 and the gear ring 45, and the rotating seat 41 drives the wheel hub 100 fixed on the rotating seat 41 to rotate. When the shape recognition sensor recognizes the fan-shaped area E on the wheel hub 100, the shape recognition sensor stops the second motor 46, stops the rotating seat 41 from rotating, and after stopping rotating, the fan-shaped area on the wheel hub 100 E is located below the polishing plate 23, and the telescopic member 14 pushes the horizontal plate 15 downward, so that the polishing plate 23 on the horizontal plate 15 is inserted downward into the fan-shaped area E on the wheel hub 100, so as to facilitate the insertion of the polishing plate 23 into the fan-shaped area E on the wheel hub 100, and polish the fan-shaped area E on the wheel hub 100. After the polishing is completed, the telescopic member 14 pulls the horizontal plate 15 and the polishing plate 23 upward through the telescopic rod, leaving between the spokes 10 of the wheel hub 100. After leaving between the spokes 10 of the wheel hub 100, the electric push rod 31 pulls the arc plate 22 close to the vertical rod 21 to restore the initial state, and the second motor 46 drives the rotating seat 41 to rotate through the gear 47 and the gear ring 45, and the rotating seat 41 drives the wheel hub 100 to rotate a certain angle, so that the next fan-shaped area above and below the wheel hub 100 rotates to the bottom of the polishing plate 23 for polishing, which plays the role of automatic position change, so that the rotating clamping device 4 and the adjusting polishing assembly 2 operate more coordinated.

[0041] When in use, the two hydraulic cylinders 44 pull the two sliding rods 42 to slide toward each other in the two second slide grooves, and the wheel hub 100 is placed on the rotating seat 41. The two hydraulic cylinders 44 push the two sliding rods 42 to slide toward the inner arc surface of the wheel hub 100 until the arc-shaped extrusion block 43 squeezes the inner arc surface B of the wheel hub 100, and fixes the wheel hub 100. The second motor 46 drives the rotating seat 41 to rotate through the gear 47 and the gear ring 45. After the shape recognition sensor recognizes the sector area E, the second motor 46 stops, so that the sector area E on the wheel hub 100 is located below the polishing plate 23, and the telescopic member 14 pushes the cross plate 15 downward, so that the polishing plate 23 on the cross plate 15 is inserted downward into the sector area E on the wheel hub 100;

[0042] The driving motor 18 drives the polishing plate 23 to rotate for polishing. When the polishing at the angle A is completed, the oil cylinder 17 drives the moving seat 16 to move, so that the polishing plate 23 moves from the angle A in the fan-shaped area E to the inner arc surface B of the wheel hub 100. When the polishing plate 23 moves to the inner arc surface B of the wheel hub, one of the polishing plates 23 contacts the inner arc surface B. Figure 7At point D, the electric push rods 31 on both sides extend to push the polishing plate 23 to squeeze the side of the spoke 10. Figure 7 The center point C makes the multiple polishing plates 23 approximately elliptical; when the electric push rod 31 moves the polishing plate 23 to polish the inner arc surface B, the arc plate 22 and the electric push rod 31 rotate, so that the other end of the polishing plate 23 is pressed against the side of the spoke 10 during the rotation. As the arc plate 22 continues to move, the position where the other end of the polishing plate 23 is pressed against the side of the spoke during the rotation gradually changes and moves toward the inner arc surface B. When moving, the other end of the polishing plate 23 polishes the angle F between the spoke 10 and the inner arc surface B of the hub, a fan-shaped After the regional polishing is completed, the telescopic member 14 pulls the horizontal plate 15 and the polishing plate 23 upward through the telescopic rod and leaves between the spokes 10 of the wheel hub 100. After leaving between the spokes 10 of the wheel hub 100, the electric push rod 31 pulls the arc plate 22 close to the vertical rod 21 to restore the initial state. The second motor 46 drives the rotating seat 41 to rotate through the gear 47 and the gear ring 45. The rotating seat 41 drives the wheel hub 100 to rotate a certain angle, so that the next sector-shaped area above the wheel hub 100 rotates to the bottom of the polishing plate 23 for polishing. The polishing is repeated many times until all sector-shaped areas E on the wheel hub 100 are polished.
