[0028] like Figure 1-5 As shown, a self-lubricating bearing plate surface grinding device includes:

[0029] Support plate 1, support rod 15 is provided on the support plate 1;

[0030] The grinding unit 2 is slidably connected to the support rod 15 and includes a slider 21 and a grinding disc 291 disposed on the slider 21. The slider 21 is located on the support rod 15 and slides thereon.

[0031] The clamping unit 4 is arranged on the support plate 1, and the clamping unit 4 includes a second screw 42, a base plate 40 and a clamping portion 411 arranged in a linear array on the base plate 40, and a second clamping block 44 is provided on the clamping portion 411, and the second screw 42 is threadedly connected to a first clamping block 41 that cooperates with the second clamping block 44, the first clamping block 41 is located on the base plate 40 and slides, and the clamping portion 411 is located directly below the grinding disc 291.

[0032] Specifically, at least two support rods 15 are provided on the support plate 1, and the two support rods 15 serve as a guide for the grinding unit 2, so that the grinding unit 2 can only slide back and forth along the support rods 15, and the second screw 42 in the clamping unit 4 is rotatably connected to the two support plates 1. When the self-lubricating bearing plate needs to be polished, the self-lubricating bearing plates are placed one by one on the clamping part 411, and one side thereof is fitted with the second clamping block 44. After the placement is completed, the second screw 42 is rotated to drive the first clamping block 41 to slide toward the second clamping block 44 to complete the clamping and fixation of the self-lubricating bearing plate. The grinding unit 2 controls the rotation of the grinding disk 291 to make the grinding unit 2 reciprocate along the support rod 15, so that the grinding disk 291 contacts the self-lubricating bearing plate to complete the surface grinding, thereby completing the grinding of multiple self-lubricating bearing plates, thereby improving the grinding efficiency.

[0033] As an embodiment further provided by the present invention, a positioning plate 45 is symmetrically and slidingly arranged on the clamping portion 411, a rubber block 452 is arranged on the positioning plate 45, and a spring 43 is arranged between the positioning plate 45 and the clamping portion 411. When the self-lubricating bearing plate is fixed to the clamping unit 4, the two positioning plates 45 can be manually pushed to slide relative to each other so that the self-lubricating bearing plate is placed between the two positioning plates 45. At this time, under the elastic resistance of the spring 43, the self-lubricating bearing plate is limited and clamped, and then the second screw 42 can be rotated to fix the self-lubricating bearing plate through the first clamping block 41 and the second clamping block 44.

[0034] As an embodiment further provided by the present invention, an extension portion 451 is provided on the positioning plate 45, and the extension portion 451 and the clamping portion 411 form an accommodating space. The spring 43 is located in the accommodating space. The extension portion 451 is in the shape of a long rectangular block, which can reduce the dust generated by grinding from entering the accommodating space and affecting the elastic properties of the spring 43.

[0035] As an embodiment further provided by the present invention, a transmission rod 14 is provided on the support plate 1, and one end of the transmission rod 14 is fixed to the first motor 11 on the support plate 1. A transmission block 22 is threadedly connected to the transmission rod 14, and the transmission block 22 cooperates with the slider 21. The transmission rod 14 rotates to drive the grinding unit 2 to slide back and forth on the support rod 15. The first motor 11 and the second motor 23 are both model: MHMF042L1U4-1116, but the transmission power of the two motors is different. The first motor 11 is fixed to one side of the support plate 1 through the connecting frame 12, and the transmission rod 14 is controlled to rotate by the first motor 11. Since the transmission block 22 is threadedly connected to the transmission rod 14, the transmission block 22 is linked to the slider 21 to perform reciprocating motion on the support rod 15.

The bracket 26 is clamped on the slider 21, and a rotating rod 29 is provided at the axis of the second pulley 27. A grinding disk 291 is provided at one end of the rotating rod 29. When grinding is required, the second motor 23 runs so that the first pulley 231 controls the rotation of the second pulley 27 through the synchronous belt 28, that is, controls the rotation of the grinding disk 291 on the rotating rod 29, and grinds the surface of the self-lubricating bearing plate through the grinding disk 291. The grinding disk 291 is fixed to the rotating rod 29 by bolts and can be replaced after wear due to long-term use.

[0037] As an embodiment further provided by the present invention, a guide sleeve 24 is provided on the bracket 26, and a first screw 25 is provided at the axis of the guide sleeve 24. The first screw 25 cooperates with the rotating rod 29. A small motor can be provided at one end of the first screw 25 to control the forward and reverse rotation of the first screw 25. The screw is rotated to push the rotating rod 29 to slide axially through the first screw 25, so that the grinding disc 291 is close to the self-lubricating bearing plate on the clamping part 411.

[0038] As an embodiment further provided by the present invention, a guide plate 251 is provided at one end of the first screw 25, and a rotating sleeve 252 rotatably connected to the guide plate 251 is rotatably connected to the rotating rod 29. The guide plate 251 slides in the guide sleeve 24, and the guide plate 251 is rotatably connected to the first screw 25, so that the guide plate 251 can only slide axially to push the rotating rod 29, and the rotating sleeve 252 improves the rotation effect of the rotating rod 29.

[0039] As an embodiment further provided by the present invention, a triangular bracket 17 is provided on the support plate 1, and the triangular bracket 17 cooperates with the base plate 40.

The flap 32 is a transparent plate. One end of the protective cover 3 is clamped to the support plate 1, and the other end is fixed by magnetic attraction. When the self-lubricating bearing plate is clamped, the flap 32 can be flipped relative to the protective cover 3 so that the self-lubricating bearing plate can be assembled on the base plate 40. The flap 32 is made of a transparent material, and the polishing state of the self-lubricating bearing plate can be observed. Furthermore, hand-gripping grooves 33 are symmetrically opened on the protective cover 3 to facilitate manual separation of the protective cover 3 from the support plate 1.

[0041] As an embodiment further provided by the present invention, a magnetic block 13 is provided on the support plate 1, and the magnetic block 13 cooperates with the protective cover 3. The magnetic block 13 is inserted into the support plate 1, so that the protective cover 3 can better fit the outer wall of the support plate 1 through the support plate 1.

[0042] Working principle: First, push the two positioning plates 45 to slide relative to each other, place the self-lubricating bearing plate between the two positioning plates 45, and make one side of the self-lubricating bearing plate fit onto the second clamping block 44. According to the above installation process, the self-lubricating bearing plates are placed one by one on the clamping part 411. After all are installed, the second screw 42 can be rotated to control the first clamping block 41 located on the base plate 40 to slide toward the second clamping block 44 until the self-lubricating bearing plate is clamped. Then the second motor 23 runs to make the first pulley 231 drive the second pulley 27 to rotate through the synchronous belt 28, that is, to rotate the grinding disk 291 on the rotating rod 29. At the same time, the first motor 11 controls the transmission rod 14 to rotate, thereby controlling the grinding unit 2 located on the transmission rod 14 to slide back and forth left and right, so as to grind multiple self-lubricating bearing plates, thereby improving the grinding efficiency of the self-lubricating bearing plates.
