Description

Technical Field

[0001] This application relates to the field of bushing processing technology, and in particular to a grinding device for bushing processing. Background Technology

[0002] A related technology (publication number: CN221792227U) discloses a synchronous polishing device for the inner and outer rings of a bushing. After placing the bushing on two first rollers, activating a first electric cylinder drives a first slider to press down, causing the second roller to press the bushing tightly, thus fixing it in place. Then, activating a first stepper motor causes the first and second pulleys to rotate at the same speed and in the same direction, which in turn causes the two first rollers to rotate at the same speed and in the same direction, ultimately rotating the bushing above the first rollers. Finally, through two polishing rods that can move in opposite directions and rotate on their own axis, the inner and outer rings of the bushing are simultaneously polished, improving production efficiency.

[0003] In the process of implementing the technical solution disclosed herein, at least the following problems were found in the related technologies:

[0004] The synchronous polishing equipment for the inner and outer rings of this bushing is prone to slippage between the belt and pulley, making it difficult to achieve simultaneous rotation of the two first rollers at the same speed and in the same direction. Simultaneously, the second roller cannot drive the bushing to rotate, leading to slippage between the rollers and the bushing due to insufficient friction. Furthermore, since the polishing rods on both sides can only move in opposite directions, synchronous feeding is only possible, making it unsuitable for bushings with different inner and outer diameters.

[0018] This disclosure provides a grinding device for processing bushings, comprising a jig frame, a first electric push rod, a first bending plate, a first rotating shaft, a first rotating roller, a second rotating shaft, a second rotating roller, a driving component, and a grinding component. The jig frame includes a slotted hole formed in its vertical wall along its height direction, allowing relevant components of the device to pass through. The first electric push rod is mounted on the top wall of the jig frame along the height direction of the jig frame, providing driving force for linear movement. The first bending plate is mounted on the moving end of the first electric push rod and moves along the height direction of the jig frame under the drive of the first electric push rod. The first rotating shaft is rotatably mounted on the first bending plate along the length direction of the jig frame and passes through the slotted hole, supporting the first rotating roller.

Therefore, both the first rotating roller and the two second rotating rollers can provide driving force for the rotation of the bushing, thereby reducing slippage due to insufficient friction and improving the rotation effect of the clamped bushing. This also facilitates subsequent simultaneous grinding of the inner and outer surfaces of the bushing using grinding components.

[0037] Combination Figures 1 to 5As shown, this disclosure provides a grinding device for bushing processing, including a jig frame 1, a first electric push rod 2, a first bending plate 3, a first rotating shaft 4, a first rotating roller 5, a second rotating shaft 6, a second rotating roller 7, a driving component, and a grinding component. The jig frame 1 includes a strip-shaped hole formed in its vertical wall along its height direction, for the passage of relevant components of the device. The first electric push rod 2 is mounted on the top wall of the jig frame 1 along the height direction of the jig frame, providing driving force to achieve linear movement. The first bending plate 3 is mounted on the moving end of the first electric push rod 2 and moves along the height direction of the jig frame 1 under the drive of the first electric push rod 2. The first rotating shaft 4 is rotatably mounted on the first bending plate 3 along the length direction of the jig frame 1 and passes through the strip-shaped hole, supporting the mounting of the first rotating roller 5. The first rotating roller 5 is mounted on the first rotating shaft 4 and used to press the bushing. The second rotating shaft 6 is rotatably mounted on the vertical wall of the I-frame 1 along its length, and on both sides of the I-frame 1 along its width. Along the height of the I-frame 1, the two second rotating shafts 6 are located below the first rotating shaft 4, respectively, and are used to support the mounting of the second rotating rollers 7. The second rotating rollers 7 are respectively mounted on the two second rotating shafts 6, and together they support the bushing. A driving component is installed between the I-frame 1 and the first bending plate 3 to provide driving force, driving the first rotating shaft 4 to rotate in opposite directions to the two second rotating shafts 6. Grinding components are installed on the I-frame 1 and are used to grind the inner and outer surfaces of the bushing.

[0038] In this embodiment, after the bushing is placed on the two second rotating rollers 7 and sleeved outside the first rotating roller 5, the first electric push rod 2 is controlled to move the first bending plate 3 along the height direction of the I-beam frame 1, ultimately causing the first rotating roller 5 to press against the bushing placed on the two second rotating rollers 7. Then, the drive component is controlled to rotate the first rotating shaft 4 in the opposite direction to the two second rotating shafts 6, ultimately driving the two second rotating rollers 7 to rotate synchronously while simultaneously driving the first rotating roller 5 to rotate in the opposite direction. Therefore, both the first rotating roller 5 and the two second rotating rollers 7 can provide driving force for the rotation of the bushing, thereby reducing slippage caused by insufficient friction and improving the rotation effect of the clamped bushing. This facilitates subsequent grinding of the inner and outer surfaces of the bushing using a grinding component.

[0039] Optionally, combined Figure 1 , Figure 3 and Figure 4As shown, the driving component includes a third rotating shaft 8 and spur gears. The third rotating shafts 8 are rotatably mounted on the vertical wall of the I-frame 1 along its length and are evenly distributed along its width, located between the two second rotating shafts 6 on either side. Multiple third rotating shafts 8 can rotate relative to the vertical wall of the I-frame 1. Spur gears are respectively mounted on the multiple third rotating shafts 8 and the two second rotating shafts 6 on both sides, meshing sequentially to transmit driving force. Either second rotating shaft 6 can be controlled to rotate, causing the other second rotating shaft 6 to rotate synchronously.

[0040] In this embodiment, once the second rotating shaft 6 on either side is controlled to rotate, it can drive the spur gear connected to it to rotate. Then, supported by multiple third rotating shafts 8 and through inter-gear meshing, the remaining multiple spur gears can rotate continuously clockwise or counterclockwise. Ultimately, this drives the second rotating shaft 6 on the other side to rotate synchronously, realizing the synchronous rotation function of the two second rotating rollers 7.

[0041] Optionally, combined Figures 1 to 4 As shown, the driving component also includes a first seated bearing 9, a splined shaft 10, a first bevel gear, a second bevel gear, a second seated bearing 11, a splined sleeve 12, a third bevel gear, and a fourth bevel gear. The first seated bearing 9 is mounted on the first bending plate 3 to support the rotatable splined shaft 10. The splined shaft 10 is mounted on the first seated bearing 9 along the height direction of the I-beam frame 1 and can rotate under the support of the first seated bearing 9. The first bevel gear is mounted on the splined shaft 10, and the second bevel gear meshes with the first bevel gear and is mounted on the first rotating shaft 4. The first and second bevel gears jointly transmit driving force and change the direction of the force. The second seated bearing 11 is mounted on the vertical wall of the I-beam frame 1 to support the rotatable splined sleeve 12. The splined sleeve 12 is slidably fitted onto the splined shaft 10 and mounted on the second seated bearing 11. It can rotate under the support of the second seated bearing 11 and, together with the splined shaft 10, transmits torque. The third bevel gear is mounted on the outer wall of the spline sleeve 12. The fourth bevel gear meshes with the third bevel gear and is mounted on the corresponding third rotating shaft 8. The third and fourth bevel gears jointly transmit driving force and change the direction of the force. The second rotating shaft 6 on either side can be controlled to rotate, causing the first rotating shaft 4 to rotate in the opposite direction.

[0042] In this embodiment, after the second rotating shaft 6 on either side is controlled to rotate, the meshing of multiple spur gears will drive one of the third rotating shafts 8 to rotate synchronously. Then, under the meshing of the third and fourth bevel gears, the spline sleeve 12 will rotate, thereby driving the spline shaft 10 to rotate. Then, under the meshing of the first and second bevel gears, the first rotating shaft 4 will rotate in the opposite direction, ultimately driving the first roller 5 to rotate in the opposite direction.

[0043] Optionally, combined Figure 1 and Figure 4 As shown, the driving component also includes a motor 13 and a coupling 14. The motor 13 is mounted on the bottom wall of the I-beam frame 1 along the length of the frame and is used to provide driving force to achieve the rotational motion function. The coupling 14 is installed between the rotating end of the motor 13 and the second rotating shaft 6 on either side and is used to transmit the driving force.

[0044] In this embodiment, the control motor 13 operates, and through the coupling 14, it drives the second rotating shaft 6 on one side to rotate. Ultimately, this drives the second rotating shaft 6 on the other side to rotate in the opposite direction, and simultaneously drives the first rotating shaft 4 to rotate in the opposite direction, thus achieving the function of automatic synchronous rotation of the second rotating rollers 7 on both sides while the first rotating roller 5 automatically rotates in the opposite direction.

[0045] Optionally, combined Figure 1 As shown, the grinding component includes a second electric push rod 15, a second bending plate 16, a first drive motor 17, and a first grinding roller 18. The second electric push rod 15 is mounted on the top wall of the I-beam frame 1 along its height direction, providing driving force for linear movement. The second bending plate 16 is mounted on the moving end of the second electric push rod 15 and passes through a slotted hole, moving along the height direction of the I-beam frame 1 under the drive of the second electric push rod 15. The first drive motor 17 is mounted on the second bending plate 16 along the length direction of the I-beam frame 1, providing driving force for rotational movement. The first grinding roller 18 is mounted on the rotating end of the first drive motor 17 and rotates under the drive of the first drive motor 17.

[0046] In this embodiment, controlling the second electric push rod 15 to operate will drive the second bending plate 16 to move along the height direction of the I-beam frame 1, ultimately driving the first grinding roller 18 to move along the height direction of the I-beam frame 1. Controlling the first drive motor 17 to operate will drive the first grinding roller 18 to rotate. Therefore, by cooperating with the second electric push rod 15 and the first drive motor 17, the movement and rotation functions of the first grinding roller 18 can be realized, ultimately completing the grinding work on the outer surface of the bushing.

[0047] Optionally, combined Figure 1As shown, the grinding component also includes a third electric push rod 19, a third bending plate 20, a second drive motor 21, and a second grinding roller 22. The third electric push rod 19 is mounted on the top wall of the I-frame 1 along its height direction, providing driving force for linear movement. The third bending plate 20 is mounted on the moving end of the third electric push rod 19 and passes through a slotted hole, moving along the height direction of the I-frame 1 under the drive of the third electric push rod 19. The second drive motor 21 is mounted on the third bending plate 20 along the length direction of the I-frame 1, providing driving force for rotational movement. The second grinding roller 22 is mounted on the rotating end of the second drive motor 21 and rotates under the drive of the second drive motor 21. Along the height direction of the I-frame 1, the second grinding roller 22 is located below the first grinding roller 18.

[0048] In this embodiment, controlling the third electric push rod 19 to operate will drive the third bending plate 20 to move along the height direction of the I-beam frame 1, ultimately driving the second grinding roller 22 to move along the height direction of the I-beam frame 1. Controlling the second drive motor 21 to operate will drive the second grinding roller 22 to rotate. Therefore, by cooperating with the third electric push rod 19 and the second drive motor 21, the movement and rotation functions of the second grinding roller 22 can be realized, ultimately completing the grinding work on the inner side of the bushing.

[0049] Optionally, combined Figure 1 , Figure 2 and Figure 4 As shown, it also includes a third seated bearing 23. The third seated bearing 23 is fitted onto the first rotating shaft 4 and mounted on the first bending plate 3.

[0050] In this embodiment, a third bearing 23 with a mounting plate is also included, which is fitted onto the first rotating shaft 4 and mounted on the first bending plate 3. The third bearing 23 is used to reduce the friction between the first rotating shaft 4 and the first bending plate 3 and to improve the accuracy of the first rotating shaft 4 when rotating relative to the first bending plate 3.

[0051] Optionally, combined Figure 1 and Figure 4 As shown, it also includes a fourth seated bearing 24. The fourth seated bearing 24 is respectively mounted on the second rotating shafts 6 on both sides, and is installed on the vertical wall of the I-frame 1.

[0052] In this embodiment, a fourth bearing 24 with a mounting seat is further included, which is respectively fitted onto the second rotating shafts 6 on both sides and mounted on the vertical wall of the I-frame 1. The fourth bearings 24 on both sides are used to reduce the friction between the second rotating shafts 6 on both sides and the vertical wall of the I-frame 1, and to improve the rotational accuracy of the second rotating shafts 6 on both sides relative to the vertical wall of the I-frame 1.
