Description

Technical Field

[0001] This application relates to the field of bushing machining technology, and in particular to a bushing machining apparatus. Background Technology

[0002] A bushing is a component used in bearings. Typically, bushings are installed inside bearings to reduce friction and wear. Bushings are usually made of metal, plastic, or other wear-resistant materials, possessing good wear resistance and lubrication properties to ensure a smooth contact surface between the shaft and the bearing, reducing friction and providing protection and support during operation.

[0003] Chinese invention patent CN210908214U discloses a processing device for metal bushings, including a worktable and a fixed block. A bracket is fixedly installed on one side of the top of the worktable, and a threaded rod is rotatably connected to the inner wall of the bracket and a limit rod is fixedly installed. A slider is threadedly connected to the outer wall of the threaded rod, and the slider is also sleeved on the limit rod. A lower clamping plate is fixedly installed at the bottom of one side of the bracket, and an upper clamping plate located directly above the lower clamping plate is fixedly installed on one side of the slider.

[0004] In the aforementioned metal bushing processing device, the upper and lower clamping plates hold the bushing. When the drill bit processes the bushing, the bushing is prone to rolling on the lower clamping plate under the force applied by the drill bit, causing the bushing to deviate from the set position and thus affecting the processing quality of the bushing. Summary of the Invention

[0005] In order to make the bushing less prone to movement during processing and improve the stability of the bushing, this application provides a bushing processing device.

[0006] The present application provides a bushing processing device, which adopts the following technical solution:

[0007] A bushing processing apparatus includes a frame, with the bushing located on and connected to the frame. It also includes a vertical plate, a connecting ring, a drive mechanism, abutting plates, and abutting mechanisms. The vertical plate is disposed on and located on the frame, connected to the frame, and its sidewall contacts the bushing. The connecting ring is sleeved on the bushing, and its sidewall connects to the sidewall of the vertical plate. Multiple abutting plates are provided, all located within the connecting ring, and evenly distributed along the circumference of the connecting ring. The sidewall of the abutment plate is connected to the vertical plate, and each abutment plate abuts against the outer sidewall of the bushing. There are multiple driving mechanisms and abutment mechanisms, and each driving mechanism and abutment mechanism corresponds to a multiple abutment plate. Each driving mechanism is located on the connecting ring, and each driving mechanism is connected to the abutment plate and is used to drive the abutment plate to move radially along the connecting ring. Each abutment mechanism is located on the connecting ring, and each abutment mechanism is connected to the abutment plate and is used to drive the abutment plate to rotate.

[0008] By adopting the above technical solution, the vertical plate supports the connecting ring, the drive mechanism abutment plate, and the abutment mechanism. After the worker transfers the bushing to the vertical plate, the abutment plate is adjusted. First, the drive mechanism moves one end of the abutment plate along the connecting ring until one end of the abutment plate is transferred to the set position. Then, the worker adjusts the abutment mechanism so that the other end of the abutment plate is transferred to the set position, thereby abutting and limiting the bushing, thus improving the stability of the bushing and making it less prone to vibration during bushing processing, thereby improving the processing quality of the bushing.

[0009] Preferably, the vertical plate has multiple driving slots, which are evenly distributed along the circumference of the connecting ring. Each driving slot corresponds to each abutment plate. The driving mechanism includes a driving block, a driving motor, and a driving screw. One side of the driving block is connected to the side wall of the abutment plate, and the other side of the driving block extends into the driving slot and contacts the side wall of the driving slot. The driving motor is located on the vertical plate and connected to the vertical plate. The output shaft of the driving motor is coaxially connected to the driving screw. The driving screw is located on the vertical plate, and the axial direction of the driving screw is consistent with the radial direction of the connecting ring. One end of the driving screw is threaded through the connecting ring and connected to the driving block.

[0010] By adopting the above technical solution, the staff starts the drive motor, and the output shaft of the drive motor rotates, which drives the screw to rotate synchronously. Through the drive groove, the drive block moves along the length of the drive groove, so that one end of the abutment plate moves with the drive plate, which makes it convenient for the staff to adjust the position of the abutment plate, and thus facilitates the abutment plate to be abutted and limited.

[0011] Preferably, each of the abutting plates has an abutting groove on the end away from the bushing. The length direction of the abutting groove is consistent with the length direction of the abutting plate. The abutting mechanism includes an abutting block, an abutting rod, and an abutting screw. One side of the abutting block is located in the abutting groove and contacts the side wall of the abutting groove. The other side of the abutting block is connected to the abutting rod. The axial direction of the abutting rod is consistent with the radial direction of the connecting ring. The end of the abutting rod away from the abutting block is coaxially connected to the abutting screw. The axial direction of the abutting screw is consistent with the radial direction of the connecting ring. One end of the abutting screw is threaded through the connecting ring and extends to the outside of the connecting ring.

[0012] By adopting the above technical solution, when one end of the abutment plate is transmitted to the set position, the operator rotates the abutment screw, thereby driving the abutment rod and the abutment block to move along the axial direction of the abutment screw. Through the abutment groove, the other end of the abutment plate is transmitted to the set position, thereby enabling the abutment plate to abut and limit the bushing, improving the stability of the bushing.

[0013] Preferably, each of the abutting rods is provided with a connecting rod, the connecting rod being located at the end of the abutting rod away from the abutting block, and a connecting groove is coaxially formed on the connecting rod, the side wall of the connecting groove contacting the side wall of the abutting rod, and a limiting mechanism is provided in the connecting groove, the limiting mechanism being connected to the abutting rod and used to limit the abutting rod.

[0014] By adopting the above technical solution, the connecting groove on the connecting rod buffers the abutment rod. When the drive screw moves radially along the connecting ring, the abutment plate is not easily jammed through the connecting groove, which makes it convenient for the operator to adjust the abutment plate. At the same time, the abutment rod is abutted and limited by the limiting mechanism, so that after the abutment rod is transmitted to the set position, it abuts and limits the abutment rod, thereby limiting the abutment plate and improving the stability of the bushing.

[0015] Preferably, a transmission groove is formed on the side wall of the connecting groove, the length direction of the transmission groove is consistent with the axial direction of the connecting rod, a sliding groove is formed on the side wall of the abutting rod, the length direction of the sliding groove is consistent with the axial direction of the abutting rod, a limiting groove is formed on the side wall of the sliding groove, the length direction of the limiting groove is consistent with the radial direction of the abutting rod, the limiting mechanism includes a slider, a pushing member and a resetting member, the slider is located in the connecting groove, one side of the slider is in contact with the side wall of the sliding groove, the other side of the slider is in contact with the side wall of the transmission groove, the pushing member is located in the transmission groove, the pushing member is in contact with the slider and is used to drive the slider to be transmitted into the limiting groove, and the resetting member is connected to the slider and is used to drive the slider to be transmitted into the sliding groove.

[0016] By adopting the above technical solution, when the abutting rod moves in the connecting groove on the connecting rod, the slider moves in the transmission groove and the slide groove. When the abutting rod is transmitted to the set position, the operator adjusts the pushing component so that one side of the slider contacts the side wall of the limiting groove, thereby limiting the abutting rod and improving the stability of the abutting rod. At the same time, when the abutting rod moves, the operator adjusts the pushing component so that the slider disengages from the limiting groove, and through the reset component, the slider can be easily lifted and lowered in the slide groove.

[0017] Preferably, a pushing groove is formed on the side wall of the transmission groove, the length direction of the pushing groove is consistent with the radial direction of the connecting rod, the pushing component includes a pushing block and a cylinder, the pushing block is located in the pushing groove and is used to contact the slider, the cylinder is located on the connecting rod, the cylinder body of the cylinder is connected to the side wall of the connecting rod, the axial direction of the piston rod of the cylinder is consistent with the radial direction of the connecting rod, and the piston rod of the cylinder extends into the pushing groove after passing through the connecting rod and is connected to the pushing block.

[0018] By adopting the above technical solution, the operator starts the cylinder, and the piston rod of the cylinder extends and retracts, causing the push block to move synchronously in the push groove until the push block contacts the slider, and causes the slider to move radially along the abutment rod until one side of the slider extends into the limiting groove, thereby abutting and limiting the abutment rod and improving the stability of the abutment rod.

[0019] Preferably, the reset component includes a reset plate and a spring. The reset plate is located in the limiting groove and contacts the side wall of the limiting groove. The spring is located in the limiting groove, with one end of the spring connected to the side wall of the limiting groove and the other end of the spring connected to the side wall of the reset plate.

[0020] By adopting the above technical solution, when the piston rod of the cylinder moves away from the abutment rod, the reset plate moves along the side closer to the cylinder through the elastic potential energy of the spring, thereby driving the slider to move synchronously until one side of the slider disengages from the side wall of the limiting groove, thus facilitating the movement of the slider in the slide groove and the transmission groove.

[0021] Preferably, the frame is provided with a collection box, an adsorption tube and a negative pressure source. The collection box has an opening and is located at the bottom of the bushing. The bottom of the collection box is connected to the frame. One end of the adsorption tube is connected to the collection box and the other end of the adsorption tube is connected to the negative pressure source. The negative pressure source is located on one side of the collection box and is connected to the frame.

[0022] By adopting the above technical solution, the collection box is used to collect debris and other dirt on the bushing. When the staff starts the negative pressure source, the dirt is transferred to the collection box through the adsorption tank, which makes it convenient for the staff to centrally process the dirt on the bushing, saving time and effort.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The operator transfers the bushing to the vertical plate and adjusts the drive mechanism and the abutment mechanism so that the abutment plate is transferred to the set position. Through multiple abutment plates, the bushing is abutted and limited, so that the bushing is not easy to shake during the processing, thus improving the stability of the bushing and improving the processing quality of the bushing.

[0025] 2. By using the pusher, when the abutment rod is transmitted to the set position in the connecting groove, the operator adjusts the pusher so that one side of the slider is transmitted to the limiting groove, thereby limiting the abutment rod and improving the stability of the abutment rod, which in turn improves the stability of the abutment plate, thus improving the processing quality of the bushing.

[0026] 3. The collection box located below the bushing is used to collect debris and other dirt on the bushing. When the staff starts the negative pressure source, the dirt is transported to the collection box by its own gravity and the airflow, which makes it convenient for the staff to centrally process the dirt on the bushing, saving time and effort.

[0032] The present application will be further described in detail below with reference to all the accompanying drawings.

[0033] This application discloses a bushing processing apparatus.

[0034] Reference Figure 1 and Figure 2 A bushing processing device includes a frame 1, on which a vertical plate 2, a connecting ring 22, and an abutment plate 3 are mounted. The bottom of the vertically arranged vertical plate 2 is fixedly connected to the frame 1, and the bushing 14 is located on and in contact with the vertical plate 2. The vertical plate 2 has multiple drive grooves 21, specifically three, which are evenly distributed along the circumference of the bushing 14. The length direction of each drive groove 21 is consistent with the radial direction of the bushing 14, and each drive groove 21 is T-shaped.

[0035] A vertically arranged connecting ring 22 is fitted onto the bushing 14, and the side wall of the connecting ring 22 is fixedly connected to the side wall of the vertical plate 2. There are multiple abutment plates 3, specifically three, all located within the connecting ring 22. The three abutment plates 3 are evenly distributed along the circumference of the connecting ring 22, corresponding one-to-one with three drive grooves 21. The side wall of each abutment plate 3 is connected to the vertical plate 2, and each abutment plate 3 abuts against the outer side wall of the bushing 14. An abutment groove 31 is formed on the side of the abutment plate 3 away from the bushing 14, and the length direction of the abutment groove 31 is consistent with the length direction of the abutment plate 3. Each abutment groove 31 is T-shaped. The three abutment plates 3 are used to abut and limit the bushing 14, thereby improving the stability of the bushing 14 and thus improving the machining quality of the bushing 14.

[0036] Reference Figure 1 and Figure 2 The frame 1 is equipped with a collection box 11, an adsorption tube 12, and a negative pressure source 13. The collection box 11, with its opening, is located at the bottom of the bushing 14, and its bottom is detachably connected to the frame 1 by bolts. This allows waste and other contaminants on the bushing 14 to be transferred into the collection box 11 under the influence of their own gravity. One end of the adsorption tube 12 is connected to the bottom of the collection box 11, and the other end is connected to the negative pressure source 13, which includes a vacuum pump. The negative pressure source 13 is located on one side of the collection box 11 and is fixedly connected to the frame 1. Through the adsorption effect of the negative pressure source 13, contaminants are more easily transferred into the collection box 11 by the airflow, making it easier for staff to collect and process contaminants and improving the cleanliness of the frame 1.

[0037] Reference Figure 2 and Figure 3 Multiple drive mechanisms 4 and multiple abutment mechanisms 5 are installed on the connecting ring 22. Specifically, there are three drive mechanisms 4 and three abutment mechanisms 5, and the three drive mechanisms 4 and the three abutment mechanisms 5 are evenly distributed along the circumference of the connecting ring 22. Each drive mechanism 4 and each abutment mechanism 5 corresponds one-to-one with each abutment plate 3.

[0038] Each drive mechanism 4 includes a drive block 41, a drive motor 42, and a drive screw 43. The drive block 41 is T-shaped, with one side hinged to the side wall of the abutment plate 3, and the other side extending into the drive groove 21 and contacting the side wall of the drive groove 21. The drive motor 42 is located on the vertical plate 2 and fixedly connected to it. The output shaft of the drive motor 42 is coaxially fixedly connected to the drive screw 43. The drive screw 43 is located on the vertical plate 2, and its axial direction is aligned with the radial direction of the connecting ring 22. The end of the drive screw 43 away from the drive motor 42 is threaded through the connecting ring 22 and rotatably connected to the drive block 41.

[0039] The staff starts the drive motor 42, and the output shaft of the drive motor 42 rotates, which drives the drive screw 43 to rotate synchronously. Through the drive groove 21, the drive block 41 moves along the length direction of the drive groove 21, so that one end of the abutment plate 3 is transmitted to the set position under the drive of the drive block 41.

[0040] Reference Figure 2 and Figure 4 Each abutment mechanism 5 includes an abutment block 51, an abutment rod 52, and an abutment screw 53. The abutment block 51 is T-shaped, with one side of the abutment block 51 located within the abutment groove 31 and in contact with the side wall of the abutment groove 31. The other side of the abutment block 51 is hinged to the abutment rod 52. The axial direction of the abutment rod 52 is aligned with the radial direction of the connecting ring 22. A sliding groove 61 is provided on the side wall of the abutment rod 52, with the length direction of the sliding groove 61 aligned with the axial direction of the abutment rod 52. A limiting groove 62 is provided on the side wall of the sliding groove 61, with the length direction of the limiting groove 62 aligned with the radial direction of the abutment rod 52.

[0041] Each abutment rod 52 has a connecting rod 7 mounted on its end away from the abutment block 51. A connecting groove 71 is coaxially formed on the connecting rod 7, with its sidewall contacting the sidewall of the abutment rod 52. A transmission groove 72 is formed on the sidewall of the connecting groove 71, with its length aligned with the axial direction of the connecting rod 7. A pushing groove 73 is formed on the sidewall of the transmission groove 72, with its length aligned with the radial direction of the connecting rod 7. The end of the connecting rod 7 away from the abutment rod 52 is rotatably connected to the abutment screw 53 via a bearing. The axial direction of the abutment screw 53 is aligned with the radial direction of the connecting ring 22, and the end of the abutment screw 53 away from the connecting rod 7 is threaded through the connecting ring 22 and extends beyond it.

[0042] Each connecting groove 71 is equipped with a limiting mechanism 8, which includes a slider 81, a pushing member 82, and a resetting member 83. The slider 81 is located in the connecting groove 71, with one side of the slider 81 contacting the side wall of the slide groove 61 and the other side of the slider 81 contacting the side wall of the transmission groove 72. A baffle 9 is installed at one end of the connecting rod 7 near the abutting rod 52. The baffle 9 is fixedly connected to the bottom of the connecting rod 7, and the side wall of the baffle 9 is used to abut against the slider 81, thereby making it difficult for the slider 81 to detach from the slide groove 61 and the transmission groove 72.

[0043] The pusher 82 includes a push block 821 and a cylinder 822. The push block 821 is located in the push groove 73 and is used to contact the slider 81. The cylinder 822 is located on the connecting rod 7. The cylinder body of the cylinder 822 is fixedly connected to the side wall of the connecting rod 7. The axial direction of the piston rod of the cylinder 822 is consistent with the radial direction of the connecting rod 7. The piston rod of the cylinder 822 passes through the connecting rod 7 and extends into the push groove 73 and is fixedly connected to the push block 821.

[0044] The reset component 83 includes a reset plate 831 and a spring 832. The inclined reset plate 831 is located in the limiting groove 62 and contacts the side wall of the limiting groove 62. The spring 832 is located in the limiting groove 62, and one end of the spring 832 is fixedly connected to the side wall of the limiting groove 62, while the other end of the spring 832 is fixedly connected to the side wall of the reset plate 831.

[0045] The operator rotates the abutting screw 53, which moves radially along the connecting ring 22, thereby driving the connecting rod 7 to move synchronously. When the driving screw 43 rotates, the abutting screw 53 is not easily jammed through the connecting groove 71, thus making it convenient for the operator to adjust the abutting screw 53. Through the slide groove 61 and the transmission groove 72, the abutting rod 52 moves synchronously under the drive of the slider 81, thereby causing the abutting block 51 to move synchronously. Through the abutting groove 31, the end of the abutting plate 3 away from the driving block 41 is transmitted to the set position, thereby causing both ends of the abutting plate 3 to be transmitted to the set position. At this time, the operator adjusts the cylinder 822. The piston rod of the cylinder 822 extends and retracts, causing the pushing block 821 to move synchronously until the pushing block 821 contacts the slider 81 and pushes the slider 81 to move along the side away from the cylinder 822. The slider 81 drives the reset plate 831 to move in the direction away from the cylinder 822. The spring 832 is compressed until one side of the slider 81 contacts the side wall of the limiting groove 62, thereby abutting and limiting the abutting rod 52.

[0046] When the operator needs to adjust the position of the abutment rod 52, the operator starts the cylinder 822. The piston rod of the cylinder 822 moves along the end away from the limiting groove 62. At this time, the push block 821 moves synchronously. Through the elastic potential energy of the spring 832, the reset plate 831 moves in the direction away from the limiting groove 62, thereby driving the slider 81 to move synchronously until the slider 81 disengages from the limiting groove 62. This makes it convenient for the operator to adjust the position of the abutment rod 52, and then convenient for the operator to adjust the abutment plate 3. This allows multiple abutment plates 3 to abut and limit the bushing 14, making it less likely for the bushing 14 to move arbitrarily during processing, thereby improving the stability of the bushing 14.

[0047] The implementation principle of the processing device for bushing 14 in this application embodiment is as follows: the operator transfers the bushing 14 to the vertical plate 2, and then starts the drive motor 42. The output shaft of the drive motor 42 rotates and drives the screw 43 to rotate synchronously, thereby driving the drive plate to move synchronously. Through the drive groove 21, the drive block 41 moves along the length direction of the drive groove 21, thereby driving the abutment plate 3 to move synchronously until one end of the abutment plate 3 is transferred to the set position.

[0048] The operator rotates the abutting screw 53, which drives the connecting rod 7 to move radially along the connecting ring 22. The end of the abutting rod 52 contacts the top of the connecting groove 71, thereby driving the abutting rod 52 to move synchronously, which in turn drives the abutting block 51 to move synchronously. Through the abutting groove 31, the other end of the abutting plate 3, driven by the abutting block 51, is transferred to the set position away from the drive motor 42, ultimately causing the abutting plate 3 to be transferred to the set position. At this time, the operator starts cylinder 822 again. The piston rod of cylinder 822 extends and retracts, causing push block 821 to move along the direction close to limit groove 62, thereby causing slider 81 to move synchronously. After slider 81 contacts reset plate 831, slider 81 continues to move along the side away from cylinder 822 until the side wall of slider 81 contacts the side wall of limit groove 62, thereby making slider 81 abut against and limit the abutting rod 52, improving the stability of abutting rod 52, and thus improving the stability of abutting plate 3, thereby abutting and limiting the bushing 14, improving the stability of bushing 14, and thus making bushing 14 less prone to shaking during processing. At the same time, it is convenient for operators to operate, saving time and effort.

[0049] When the operator needs to adjust the abutment rod 52, the operator activates the cylinder 822. The piston rod of the cylinder 822 extends and retracts, causing the push block 821 to move away from the limiting groove 62. At this time, the push block 821 disengages from the slider 81. Through the elastic potential energy of the spring 832, the reset plate 831 moves towards the cylinder 822, thereby causing the slider 81 to move synchronously until the side wall of the slider 81 disengages from the limiting groove 62. This makes it convenient for the operator to adjust the position of the abutment rod 52, and thus convenient for the operator to adjust the position of the abutment plate 3.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
