Description

Technical Field

[0001] This application relates to the field of grinding equipment technology, and in particular to a thrust plate grinding device. Background Technology

[0002] Thrust washers are an important component of engines. They are generally made of thin metal sheets and are mostly circular or semi-circular in shape. Their surface is usually covered with a layer of anti-friction material, which can reduce the coefficient of friction and reduce wear. When installing, thrust washers need to fit tightly with components such as journals and bearing seats to effectively withstand axial forces.

[0003] After production, the surface of the thrust washers usually has burrs, unevenness, or scratches. Direct installation will result in poor fit, gaps, affect axial positioning accuracy, and even cause vibration and noise. Therefore, the surface of the thrust washers needs to be polished after production.

[0004] However, in the existing technology, workers usually use hand-held grinding tools to grind the surface of the thrust plate. The manual grinding method is time-consuming and labor-intensive, and the grinding efficiency of the thrust plate is low. It cannot meet the grinding needs of a large number of thrust plates and has obvious shortcomings. Utility Model Content

[0005] To improve the grinding efficiency of thrust plates, this application provides a thrust plate grinding device.

[0006] The thrust plate grinding device provided in this application adopts the following technical solution: A thrust plate grinding device includes a worktable with a turntable rotatably connected to it. Multiple placement plates are evenly arranged circumferentially around the turntable, and each placement plate has multiple placement slots for placing thrust plates. A support frame is provided on the worktable, and a grinding assembly is mounted on the support frame. The grinding assembly includes a mounting plate on the support frame, and a first motor is mounted on the mounting plate. A grinding shaft is coaxially mounted on the output shaft of the first motor, and a grinding disc for grinding the thrust plate is coaxially mounted at the end of the grinding shaft, with the grinding disc abutting against the surface of the thrust plate.

[0007] By adopting the above technical solution, when grinding thrust plates, workers place multiple thrust plates into the placement slot in sequence, and then start the turntable and the first motor. The turntable rotates, causing multiple thrust plates to rotate. The first motor drives the grinding shaft to rotate, which in turn drives the grinding disc. When the thrust plate rotates and contacts the grinding disc, the grinding disc grinds it. Afterwards, the worker removes the ground thrust plate. This achieves automatic grinding of multiple thrust plates on the turntable, eliminating the need for workers to manually grind with grinding tools, thus improving the grinding efficiency of thrust plates.

[0008] Optionally, a cleaning assembly is provided on the workbench. The cleaning assembly includes a water tank disposed on the workbench, which stores cleaning fluid inside. A water pump is fixedly installed on the outer surface of the water tank. The inlet and outlet of the water pump are respectively connected to an inlet pipe and an outlet pipe. The end of the inlet pipe away from the water pump is connected to the water tank, and the end of the outlet pipe away from the water pump is positioned towards the turntable.

[0009] By adopting the above technical solution, when the polished thrust plate rotates to the cleaning component under the drive of the turntable, the water pump starts and draws out the cleaning fluid in the water tank through the inlet pipe. The cleaning fluid is sprayed onto the thrust plate through the outlet pipe. The residual metal dust and grinding debris are removed from the surface of the thrust plate by the cleaning fluid, and the surface temperature of the thrust plate is reduced at the same time to prevent the material from deforming due to the high temperature generated by polishing, thus ensuring the polishing quality of the thrust plate.

[0010] Optionally, the support frame has an adjustment groove along its length, and an adjustment component is provided in the adjustment groove. The adjustment component includes an adjustment screw rotatably connected in the adjustment groove, and an adjustment block is threaded onto the adjustment screw. The cross-section of the adjustment block and the adjustment groove are both square. The mounting plate is disposed on the adjustment block, and a drive component for driving the adjustment screw to rotate is disposed on the worktable.

[0011] By adopting the above technical solution, when the thickness of the thrust plate changes, the drive assembly drives the adjusting screw to rotate. Under the cross-sectional constraints of the adjusting groove and the adjusting block, the adjusting screw drives the adjusting block to move along the adjusting groove. The adjusting block drives the grinding assembly on the mounting plate to move towards the turntable. When the grinding disc abuts against the surface of the thrust plate, the drive assembly is turned off. The setting of the drive assembly and the adjusting assembly realizes the adjustment of the position of the grinding disc, so that the grinding assembly can adapt to the grinding needs of thrust plates of different thicknesses and specifications, thus improving the applicability of the grinding assembly.

[0012] Optionally, the drive assembly includes a worm gear fixedly connected coaxially to the adjusting screw, a worm gear meshing with the worm gear is rotatably connected in the adjusting groove, and one end of the worm gear extends out of the support frame and is coaxially provided with a rotating wheel.

[0013] By adopting the above technical solution, when the position of the grinding component needs to be adjusted, the worker rotates the rotating wheel to drive the worm to rotate. The worm meshes with the worm wheel to drive the adjusting screw to rotate, so that the adjusting block drives the mounting plate to move along the adjusting groove. At the same time, the self-locking characteristics of the worm and worm wheel prevent the grinding component from being displaced due to vibration and other factors during the grinding process, thus ensuring the stability of the grinding work.

[0014] Optionally, each of the placement slots is provided with an ejection assembly, the ejection assembly including an ejection plate slidably connected in the placement slot, a sliding groove formed on the inner sidewall opposite to the placement slot to slide with the ejection plate, an electromagnetic block embedded in the bottom wall of the placement slot, a magnetic sheet embedded in the bottom wall of the ejection plate, and a spring provided in the sliding groove, one end of the spring being disposed on the ejection plate and the other end being disposed on the inner sidewall of the sliding groove away from the electromagnetic block. In the natural state of the spring, the bottom surface of the ejection plate abuts against the bottom wall of the placement slot. When the electromagnetic block is energized, the repulsive force generated by the electromagnetic block on the magnetic sheet is greater than the elastic force of the spring.

[0015] By adopting the above technical solution, after the thrust plate is polished, the electromagnetic block is energized. The repulsive force generated between the electromagnetic block and the magnetic plate overcomes the elastic force of the spring and pushes the ejector plate to slide upward along the sliding groove. The ejector plate pushes the thrust plate to move upward, so that the end of the thrust plate extends out of the placement groove, which makes it convenient for workers to quickly and easily remove the thrust plate without having to manually pick it out, thus improving the removal efficiency of the thrust plate. After the thrust plate is removed, the electromagnetic block is de-energized, the repulsive force between the electromagnetic block and the magnetic plate disappears, the spring returns to its original position and pulls the ejector plate back to its original position, so that the bottom surface of the ejector plate abuts against the bottom wall of the placement slot, preparing for the next placement of the thrust plate, thus ensuring the continuity of the ejector assembly's operation.

[0016] Optionally, the placement plate is detachably connected to the turntable by a plurality of connecting bolts.

[0017] By adopting the above technical solution, when the placement plate is worn or needs to be replaced with a placement plate of a different specification to fit the thrust plate of a different size, the placement plate can be quickly disassembled and replaced simply by unscrewing the connecting bolts, without having to replace the entire turntable.

[0018] Optionally, a square groove is provided on the workbench, and a counterweight is provided inside the square groove. The counterweight is made of cast iron.

[0019] By adopting the above technical solution, the counterweight increases the overall weight of the grinding device, reduces the vibration caused by the rotation of the turntable and the operation of the grinding components, avoids the vibration from causing a decrease in the grinding accuracy of the thrust plate or loosening of equipment parts, and improves the stability of the equipment during operation.

[0020] Optionally, a vision inspection module is provided on the workbench, and the vision inspection module is electrically connected to the electromagnetic block through a control system.

[0021] By adopting the above technical solution, the vision inspection module performs real-time image acquisition and analysis on the polished thrust plate to determine whether the polishing quality of the thrust plate meets the standard. When the vision inspection module detects that the thrust plate is polished to a qualified standard, the control system controls the electromagnetic block to be energized, and the ejection component ejects the thrust plate. If the thrust plate is found to be unqualified, the control system controls the electromagnetic block to be de-energized, and the unqualified thrust plate remains in the placement slot, waiting for manual processing or secondary polishing. This setting realizes the automatic detection of the thrust plate and further improves the polishing efficiency of the thrust plate.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This application, by setting up a grinding component, allows workers to place multiple thrust plates into the placement slot in sequence when grinding thrust plates. Then, the turntable and the first motor are started. The turntable rotates, causing multiple thrust plates to rotate. The first motor drives the grinding shaft to rotate, causing the grinding disc to work. When the thrust plates rotate and come into contact with the grinding disc, the grinding disc grinds them. Afterward, the worker removes the ground thrust plates. This achieves automatic grinding of multiple thrust plates on the turntable, eliminating the need for workers to manually grind with grinding tools, thus improving the grinding efficiency of thrust plates. 2. This application achieves the adjustment of the grinding disc position by setting up a drive component and an adjustment component, which enables the grinding component to adapt to the grinding requirements of thrust plates of different thicknesses and specifications, thereby improving the applicability of the grinding component. 3. By setting up an ejector assembly, after the thrust plate is polished, the electromagnetic block is energized, and the repulsive force generated between the electromagnetic block and the magnetic plate overcomes the spring force to push the ejector plate to slide upward along the sliding groove. The ejector plate pushes the thrust plate to move upward, so that the end of the thrust plate extends out of the placement groove, thereby making it convenient for workers to quickly and easily remove the thrust plate without the need for manual removal, thus improving the removal efficiency of the thrust plate.

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a thrust plate grinding device.

[0029] Reference Figure 1 and Figure 2 A thrust plate grinding device includes a worktable 1, on which a turntable 2 is rotatably connected. The working principle of the turntable 2 is existing technology and will not be described in detail here. Multiple placement plates 3 are evenly installed on the upper surface of the turntable 2 along the circumference. In this embodiment, there are three placement plates 3. Each placement plate 3 has multiple placement slots 5 for placing thrust plates. The placement slots 5 are the same shape and size as the thrust plates to be ground.

[0030] Reference Figure 1 and Figure 2 Each placement plate 3 is detachably connected to the upper surface of the turntable 2 by multiple connecting bolts 4. Workers can replace the placement plate 3 by removing and installing the connecting bolts 4 to accommodate thrust plates of different sizes.

[0031] Reference Figure 1 and Figure 2 A support frame 6 is fixedly installed on the workbench 1. The support frame 6 is vertically arranged and a grinding component 7 for grinding is provided on the support frame 6. An adjustment groove 61 is opened in the vertical direction of the support frame 6. An adjustment component 9 for adjusting the position of the grinding component 7 is provided in the adjustment groove 61. Before grinding, the grinding component 7 is adjusted to the grinding position by adjusting component 9. In this way, the grinding component 7 can adapt to the grinding needs of thrust plates of different thicknesses and specifications, thus improving the applicability of the grinding component 7.

[0032] Reference Figure 1 and Figure 2The adjusting assembly 9 includes an adjusting screw 91 rotatably connected in the adjusting groove 61, and an adjusting block 92 threadedly connected to the adjusting screw 91 and slidingly engaged with the adjusting groove 61. Both the adjusting block 92 and the adjusting groove 61 have square cross-sections. The grinding assembly 7 includes a mounting plate 71 fixedly connected to the adjusting plate, and a first motor 72 fixedly mounted on the mounting plate 71. The output shaft of the first motor 72 is coaxially fixedly connected to a grinding shaft 73, and the end of the grinding shaft 73 is coaxially fixedly connected to a grinding disc 74 for grinding the thrust plate. The adjusting assembly 9 adjusts the grinding disc 74 to abut against the surface of the thrust plate.

[0033] Reference Figure 1 and Figure 2 The workbench 1 is provided with a drive assembly 10, which includes a worm gear 101 that is coaxially fixedly connected to the adjusting screw 91. A worm 102 that meshes with the worm gear 101 is rotatably connected in the adjusting groove 61. One end of the worm 102 extends out of the support frame 6 and is coaxially fixedly connected to a rotating wheel 103.

[0034] Before grinding, the worker places multiple thrust plates into the placement groove 5 in sequence. Then, the worker rotates the rotating wheel 103 to drive the worm 102 to rotate. The worm 102 meshes with the worm wheel 101 to drive the adjusting screw 91 to rotate. Under the cross-sectional constraints of the adjusting groove 61 and the adjusting block 92, the adjusting screw 91 drives the adjusting block 92 to move along the adjusting groove 61. The adjusting block 92 drives the grinding assembly 7 on the mounting plate 71 to move toward the turntable 2. When the grinding disc 74 abuts against the surface of the thrust plate, the handwheel stops rotating. After adjustment, turntable 2 and first motor 72 are started. Turntable 2 rotates, driving multiple thrust plates to rotate. First motor 72 drives grinding shaft 73 to rotate, driving grinding disc 74 to work. When the thrust plates rotate and come into contact with grinding disc 74, grinding disc 74 grinds them. Then, the worker takes out the ground thrust plates. In this way, the automatic grinding of multiple thrust plates on turntable 2 is realized, without the need for workers to manually grind with grinding tools, thus improving the grinding efficiency of thrust plates.

[0035] Reference Figure 1 and Figure 2 To improve stability during grinding, a square groove 8 is provided on the worktable 1, and a counterweight 81 is placed inside the square groove 8. The counterweight 81 is made of cast iron. By equipping the counterweight 81, the overall weight of the grinding device is increased, and the vibration caused by the rotation of the turntable 2 and the operation of the grinding components 7 is reduced.

[0036] Reference Figure 1 and Figure 2A cleaning assembly 11 is provided on the workbench 1. The cleaning assembly 11 includes a water tank 111 fixedly installed on the outer surface of the workbench 1. The water tank 111 stores cleaning fluid inside. A water pump 112 is fixedly installed on the outer surface of the water tank 111. The inlet of the water pump 112 is connected to an inlet pipe 113, and the outlet is connected to an outlet pipe 114. The end of the inlet pipe 113 away from the water pump 112 is connected to the inside of the water tank 111, and the end of the outlet pipe 114 away from the water pump 112 is set toward the placement plate 3 on the turntable 2.

[0037] When the polished thrust plate rotates to the cleaning assembly 11 driven by the turntable 2, the water pump 112 starts and draws out the cleaning fluid in the water tank 111 through the inlet pipe 113. The cleaning fluid is sprayed onto the thrust plate through the outlet pipe 114. The residual metal dust and shavings are removed from the surface of the thrust plate by the cleaning fluid, and the surface temperature of the thrust plate is reduced to prevent the material from deforming due to the high temperature generated by polishing, thus ensuring the polishing quality of the thrust plate.

[0038] Reference Figure 2 and Figure 3 Each placement slot 5 is equipped with an ejection assembly 12. The ejection assembly 12 includes an ejection plate 121 that is slidably connected in the placement slot 5. The outer surface of the ejection plate 121 is in contact with the inner side wall of the placement slot 5. The inner side walls of the placement slot 5 are provided with sliding grooves 31 that are slidably engaged with the ejection plate 121. An electromagnetic block 123 is embedded in the bottom wall of the placement slot 5, and a magnetic sheet 122 is embedded in the bottom wall of the ejection plate 121.

[0039] Reference Figure 2 and Figure 3 A vision inspection module 13 is fixedly installed on the workbench 1. The vision inspection module 13 is an industrial camera or a laser scanner. The vision inspection module 13 is electrically connected to the electromagnetic block 123 through the control system.

[0040] Reference Figure 3 Each sliding groove 31 is equipped with a spring 124. One end of the spring 124 is fixedly connected to the ejector plate 121, and the other end is fixedly connected to the inner wall of the sliding groove 31 away from the electromagnetic block 123. In its natural state, the bottom surface of the ejector plate 121 abuts against the bottom wall of the placement groove 5. When the electromagnetic block 123 is energized, the repulsive force generated by the electromagnetic block 123 on the magnetic sheet 122 is greater than the elastic force of the spring 124.

[0041] The visual inspection module 13 performs real-time image acquisition and analysis on the polished thrust plate to determine whether the polishing quality of the thrust plate meets the standard. When a defect is detected, the control system controls the electromagnetic block 123 to de-energize, and the defective thrust plate remains in the placement groove 5, waiting for secondary polishing. When the visual inspection module 13 detects that the thrust plate has passed the grinding test, the control system controls the electromagnetic block 123 to be energized. The repulsive force generated between the electromagnetic block 123 and the magnetic sheet 122 overcomes the elastic force of the spring 124 and pushes the ejector plate 121 to slide upward along the sliding groove 31. The ejector plate 121 pushes the thrust plate upward so that the end of the thrust plate extends out of the placement groove 5, which makes it convenient for workers to quickly and easily remove the thrust plate. After the thrust plate is removed, the electromagnetic block 123 is de-energized, the repulsive force between the electromagnetic block 123 and the magnetic sheet 122 disappears, the spring 124 resets and pulls the ejector plate 121 to reset, so that the bottom surface of the ejector plate 121 abuts against the bottom wall of the placement groove 5, preparing for the next placement of the thrust plate, thus ensuring the continuity of the ejector assembly 12's operation.

[0042] The implementation principle of the thrust plate grinding device in this application embodiment is as follows: Before grinding, the worker puts multiple thrust plates into the placement groove 5 in sequence. Then, the worker rotates the rotating wheel 103 to drive the worm 102 to rotate. The worm 102 meshes with the worm wheel 101 to drive the adjusting screw 91 to rotate. Under the cross-sectional constraints of the adjusting groove 61 and the adjusting block 92, the adjusting screw 91 drives the adjusting block 92 to move along the adjusting groove 61. The adjusting block 92 drives the grinding component 7 on the mounting plate 71 to move toward the turntable 2. When the grinding disc 74 abuts against the surface of the thrust plate, the handwheel stops rotating. After adjustment, turntable 2 and first motor 72 are started. Turntable 2 rotates, driving multiple thrust plates to rotate. First motor 72 drives grinding shaft 73 to rotate, driving grinding disc 74 to work. When the thrust plates rotate and come into contact with grinding disc 74, grinding disc 74 grinds them. Then, the worker takes out the ground thrust plates. In this way, the automatic grinding of multiple thrust plates on turntable 2 is realized, without the need for workers to manually grind with grinding tools, thus improving the grinding efficiency of thrust plates.

[0043] 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.
