DETAILED DESCRIPTION

[0026] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0027] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7As shown, it is a structural diagram of a surface treatment equipment for bearing production provided by an embodiment of the present invention, comprising a workbench 1, support legs 11 are fixedly installed around the bottom wall of the workbench 1, a processing cavity 13 is opened on the surface of the workbench 1, a bearing body is placed in the processing cavity 13, support rods 12 are fixedly installed around the surface of the workbench 1, a top plate 2 is fixedly installed on the top of multiple groups of support rods 12, a bearing plate 3 is arranged between the workbench 1 and the top plate 2, a grinder 5 is fixedly installed on the surface of the bearing plate 3, the output shaft of the grinder 5 extends to the bottom of the bearing plate 3 and is connected to a grinding disc 51, a lifting assembly 4 connected to the bearing plate 3 is arranged between the workbench 1 and the top plate 2, the lifting assembly 4 is used to control the bearing plate 3 to move in the vertical direction, and a control mechanism 6 that cooperates with the bearing body is arranged on the surface of the workbench 1, the control mechanism 6 includes a clamp 61, a positioning Component 62 and adjustment component 63, the clamp 61 is provided with two groups and has a semicircular structure, the positioning component 62 is located on the two opposite side walls of the processing chamber 13 and is connected to the clamp 61, the positioning component 62 is used to control the relative distribution of the two groups of clamps 61 and clamp and fix the bearing body, the adjustment component 63 includes a clamping portion 631 and a flipping portion 632, the clamping portion 631 is located on the surface of the workbench 1 and is connected to the positioning component 62, the clamping portion 631 controls the two groups of clamps 61 and the bearing body to maintain a horizontal state in the processing chamber 13 by cooperating with the positioning component 62, the flipping portion 632 is located on the bottom wall of the bearing plate 3 and is connected to the positioning component 62, when the bearing plate 3 moves in the vertical direction, the flipping portion 632 controls the clamp 61 and the bearing body to flip 180 degrees in the processing chamber 13 by cooperating with the positioning component 62.

[0029] When in use, the bearing body to be processed is placed in the processing cavity 13 and located between the two groups of clamps 61. The positioning assembly 62 adjusts the positions of the two groups of clamps 61 to squeeze and fix the bearing body. After the bearing body is fixed, the lifting assembly 4 controls the bearing plate 3 to move vertically downward, and the bearing plate 3 drives the grinder 5 and the grinding disc 51 to move downward synchronously. The grinder 5 controls the grinding disc 51 to rotate, and the grinding disc 51 can perform efficient grinding processing on the end face of the bearing. After the end face is polished, the lifting assembly 4 controls the bearing plate 3 and the grinder 5 to move upward synchronously. When the bearing plate 3 moves upward, the clamping portion 631 releases the positioning assembly 62. The flipping part 632 cooperates with the positioning assembly 62 to control the clamp 61 and the bearing body to flip 180 degrees in the processing cavity 13, so that the other unpolished end face of the bearing body rotates to the upper surface. At this time, the clamping part 631 restricts the positioning assembly 62 again, so that the two sets of clamps 61 and the bearing body remain in a horizontal state in the processing cavity 13. The lifting assembly 4 controls the supporting plate 3 and the grinder 5 to move downward again, and the grinding disc 51 can efficiently grind the end face of the upper surface of the bearing body. After the grinding is completed, the positioning assembly 62 adjusts the position of the clamp 61, so that the polished bearing body can be conveniently removed.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, as a preferred embodiment of the present invention, the lifting assembly 4 includes a plurality of groups of threaded rods 41 rotatably installed between the workbench 1 and the top plate 2, the threaded rods 41 are threadedly connected to the bearing plate 3, and a synchronous gear plate 42 is fixedly installed on the surface of the threaded rods 41. The plurality of groups of synchronous gear plates 42 are commonly connected to a synchronous belt 43, and the top end of a group of threaded rods 41 extends to the surface of the top plate 2 and is connected to a motor 44.

[0031] When in use, the motor 44 drives a group of threaded rods 41 to rotate and then drives the fixed toothed disc 42 to rotate. Multiple groups of fixed toothed discs 42 cooperate with the synchronous belt 43 to drive multiple groups of threaded rods 41 to rotate synchronously, thereby controlling the bearing plate 3 to move in the vertical direction, and the height of the grinder 5 and the grinding disc 51 can be conveniently adjusted.

[0032] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Fig.10As shown, as a preferred embodiment of the present invention, the positioning assembly 62 includes a supporting plate 621 rotatably installed on the opposite side walls of the processing cavity 13, and the two opposite side walls of the two groups of supporting plates 621 are respectively provided with a slide groove 622, and two groups of slide plates 623 extending to the outside of the supporting plate 621 are slidably installed in the slide groove 622, and the slide plates 623 on the surfaces of the two groups of supporting plates 621 are respectively connected to the two ends of the clamp 61, and the surface of the slide plate 623 is provided with a fixing bolt 624.

[0033] The slide plate 623 moves in the slide groove 622 to conveniently adjust the relative positions of the two groups of clamps 61, and the bearing body is placed between the two groups of clamps 61. The fixing bolts 624 and the slide plate 623 cooperate with each other to control the relative movement of the two groups of clamps 61. The two groups of clamps 61 squeeze and fix the bearing body, and then the bearing body is installed in the processing cavity 13. After grinding is completed, the fixing bolts 624 are removed, and the two groups of clamps 61 release the restrictions on the bearing body, so that the bearing body can be conveniently removed.

[0034] like Figure 1 , Figure 2 , Figure 6 , Figure 7 , Fig.10 As shown, as a preferred embodiment of the present invention, the clamping portion 631 includes two groups of relatively distributed clamping holes 6314 opened on the side wall of the carrier plate 621, and the side wall of the processing chamber 13 is provided with a receiving hole 6311 distributed relatively to the clamping hole 6314, and a clamping column 6313 cooperating with the clamping hole 6314 is slidably installed in the receiving hole 6311, and an extrusion spring 6312 is fixedly installed in the receiving hole 6311, and the telescopic end of the extrusion spring 6312 is connected to the clamping column 6313 Then, a wire groove 6315 connected to the storage hole 6311 is opened downward on the surface of the workbench 1, and a pulling rope 6316 is fixedly installed on one end of the clamping column 6313 located in the storage hole 6311. The end of the pulling rope 6316 away from the clamping column 6313 passes through the wire groove 6315 and extends to the surface of the workbench 1 and is fixedly installed with a control board 6317. The control board 6317 is made of magnetic material, and a magnetic plate 6318 that cooperates with the control board 6317 is fixedly installed on the bottom wall of the supporting plate 3.

[0035] Initially, the extrusion spring 5312 applies a thrust to the clamping column 6313, and the clamping column 6313 is inserted into the clamping hole 6314 on the surface of the carrier plate 621. The clamping column 6313 and the clamping hole 6314 cooperate with each other to fix the carrier plate 621, so that the two sets of clamps 61 and the bearing body are kept in a horizontal state in the processing cavity 13. When the carrier plate 3 moves downward to grind the bearing body, the magnetic plate 6318 on the bottom wall of the carrier plate 3 is connected to the control plate 6317 as a whole through the magnetic attraction force. After the end face grinding of the bearing body is completed, the carrier plate 3 moves upward and drives the control plate 6317 to move upward synchronously. The control plate 6317 cooperates with the pulling rope 6316 to pull the clamping column 6313 toward the storage hole 6311. At this time, the clamping column 6313 and the clamping hole 6314 are connected to the control plate 6317. The connecting holes 6314 are separated from each other, thereby releasing the restriction on the supporting plate 621. The flipping part 632 controls the supporting plate 621 to rotate one hundred and eighty degrees. The supporting plate 621 drives the two sets of clamps 61 and the bearing body to rotate synchronously one hundred and eighty degrees. When the supporting plate 621 rotates, after the control plate 6317 rises to the limit height, the supporting plate 3 continues to move upward, thereby separating the control plate 6317 and the magnetic plate 6318 from each other, and the control plate 6317 falls to the surface of the workbench 1. After the supporting plate 621 rotates one hundred and eighty degrees, the extrusion spring 5312 applies a thrust to the clamping column 6313, and the clamping column 6313 is inserted into the clamping hole 6314 on the surface of the supporting plate 621 again, and the supporting plate 621 is fixed again. The two sets of clamps 61 and the bearing body are kept in a horizontal state in the processing cavity 13 again.

[0036] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, as a preferred embodiment of the present invention, the flip part 632 includes a gear ring 6321 fixedly installed on the annular side wall of the carrying plate 621, a telescopic groove 6322 is opened on the bottom wall of the carrying plate 3, a sliding block 6324 is slidably installed in the telescopic groove 6322, the sliding block 6324 extends to the bottom of the carrying plate 3 and is fixedly installed with a vertical rod 6325, and a rack 6326 meshing with the gear ring 6321 is fixedly installed on the side wall of the vertical rod 6325, a return spring 6323 is fixedly installed in the telescopic groove 6322, the telescopic end of the return spring 6323 is connected to the sliding block 6324, and a guide part 7 cooperating with the sliding block 6324 is provided on the surface of the workbench 1. When the carrying plate 3 drives the sliding block 6324 to move in the vertical direction, the guide part 7 is used to control the sliding block 6324 to move in the horizontal direction in the telescopic groove 6322.

[0037] When the supporting plate 3 moves downward, it drives the vertical rod 6325 and the rack 6326 to move downward synchronously. At this time, the guide part 7 adjusts the position of the sliding block 6324 so that the sliding block 6324 squeezes the reset spring 6323 in the telescopic groove 6322. At this time, the rack 6326 does not contact the ring gear 6321 on the surface of the supporting disk 621 when it moves downward. When the supporting plate 3 moves upward, the guide part 7 adjusts the position of the sliding block 6324 again so that the vertical rod 6325 moves a certain distance toward the supporting disk 621. When the vertical rod 6325 drives the rack 6326 to move upward, the rack 6326 engages with the ring gear 6321 for transmission and drives the supporting disk 621 to rotate. After the supporting disk 621 rotates one hundred and eighty degrees, the rack 6326 that continues to move upward separates from the ring gear 6321.

[0038] like Figure 1 , Figure 2 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 As shown, as a preferred embodiment of the present invention, the guide portion 7 includes a vertical plate 71 fixedly installed on the surface of the workbench 1 and located outside the processing cavity 13, a first through hole 711 is provided on the surface of the supporting plate 3 to cooperate with the vertical plate 71, and a guide groove 72 is provided on the side wall of the vertical plate 71. The guide groove 72 is composed of an inner vertical groove 721, an outer vertical groove 722, a top groove 723 and a bottom groove 724. The top groove 723 is inclined and is respectively connected to the top ends of the inner vertical groove 721 and the outer vertical groove 722, the bottom groove 724 is inclined and is respectively connected to the bottom ends of the inner vertical groove 721 and the outer vertical groove 722, a baffle 725 is rotatably installed on one end of the top groove 723 close to the inner vertical groove 721 and an end of the bottom groove 724 close to the outer vertical groove 722, and a guide column 73 extending into the guide groove 72 is fixedly installed on the side wall of the sliding block 6324.

[0039] When the load-bearing plate 3 moves upward, the guide post 73 on the side wall of the sliding block 6324 moves upward synchronously in the inner vertical groove 721. When the load-bearing plate 3 moves to the highest point, the guide post 73 passes through the baffle plate 725 and moves into the top groove 723. When the load-bearing plate 3 moves downward, the baffle plate 725 restricts the guide post 73. The guide post 73 moves in the top groove 723 and further moves into the outer vertical groove 722 and continues to move downward. At this time, the vertical rod 6325 and the rack 6326 are both on the outside of the gear ring 6321. The load-bearing plate 3 moves to the highest point. When grinding at a low place, the guide column 73 passes through the baffle 725 and moves into the bottom groove 724. When the supporting plate 3 moves upward again, the baffle 725 restricts the guide column 73. The guide column 73 moves in the bottom groove 724 and further moves into the inner vertical groove 721 to continue moving upward. At this time, the guide column 73 cooperates with the sliding block 6324 to control the vertical rod 6325 to move toward the supporting plate 621. At this time, the rack 6326 on the surface of the vertical rod 6325 is engaged with the gear ring 6321 on the surface of the supporting plate 621.

[0040] like Figure 5 , Figure 8 , Fig. 9 As shown, as a preferred embodiment of the present invention, the bottom wall of the top groove 723 and the top wall of the bottom groove 724 are respectively provided with a pulling spring 8 connected to the baffle 725.

[0041] The pulling spring 8 positions the baffle 725, and the baffle 725 controls the guide column 73 to move only in one direction in the guide groove 72. The guide column 73 can only move from the top of the inner vertical groove 721 to the top groove 723 in one direction, and the guide column 73 can only move from the bottom of the outer vertical groove 722 to the bottom groove 724 in one direction.

[0042] like Figure 1 , Figure 3 , Fig.10 As shown, as a preferred embodiment of the present invention, a limit rod 10 is fixedly installed on the surface of the workbench, and the control plate 6317 is slidably installed on the outside of the limit rod 10. A shock-absorbing spring 101 located below the control plate 6317 is sleeved on the outside of the limit rod 10, and a second through hole 102 that cooperates with the limit rod 10 is opened on the surface of the supporting plate 3.

[0043] like Figure 1 , Figure 2 , Figure 7 As shown, as a preferred embodiment of the present invention, the bottom wall of the workbench 1 is provided with a dust collecting assembly 9, and the dust collecting assembly 9 includes a dust collecting box 91, and the top of the dust collecting box 91 is provided with an opening, and a top ring 92 is fixedly installed on the top wall of the dust collecting box 91, and the top ring 92 is made of magnetic material, and a magnetic strip 93 that cooperates with the top ring 92 is fixedly installed on the bottom wall of the workbench 1.

[0044] When in use, the magnetic strip 93 fixes the top ring 92 through magnetic attraction, thereby fixing the dust box 91 under the processing chamber 13, and the debris generated by grinding and polishing the bearing body can automatically fall into the dust box 91.

[0045] The working principle of the present invention is: when in use, the bearing body to be processed is placed in the processing cavity 13 and located between the two groups of clamps 61, the fixing bolts 624 and the slide plate 623 cooperate with each other to control the relative movement of the two groups of clamps 61, and the two groups of clamps 61 squeeze and fix the bearing body, and then install the bearing body in the processing cavity 13. The motor 44 drives a group of threaded rods 41 to rotate and then drives the fixed toothed disc 42 to rotate. Multiple groups of fixed toothed discs 42 and synchronous belts 43 cooperate with each other to drive multiple groups of threaded rods 41 to rotate synchronously, and then control the bearing plate 3 to move in the vertical direction, the bearing plate 3 moves vertically downward, the bearing plate 3 drives the grinder 5 and the grinding disc 51 to move downward synchronously, the grinder 5 controls the grinding disc 51 to rotate, and the grinding disc 51 can perform efficient grinding processing on the end face of the bearing.

[0046] The bearing plate 3 moves downward, driving the vertical rod 6325 and the rack 6326 to move downward synchronously. When the bearing plate 3 moves downward, the baffle 725 restricts the guide column 73, and the guide column 73 moves in the top groove 723 and further moves into the outer vertical groove 722 to continue moving downward. At this time, the vertical rod 6325 and the rack 6326 are both outside the gear ring 6321. When the bearing plate 3 moves to the lowest point and is polished, the guide column 73 passes through the baffle 725 and moves into the bottom groove 724. When the polishing of one end surface of the bearing body is completed, the bearing plate 3 moves upward, and the bearing plate 3 drives the control plate 6317 to move upward synchronously. The plate 6317 cooperates with the pulling rope 6316 to pull the clamping column 6313 to move toward the receiving hole 6311. At this time, the clamping column 6313 and the clamping hole 6314 are separated from each other to release the restriction on the carrier plate 621. The baffle 725 restricts the guide column 73, and the guide column 73 moves in the bottom groove 724 and further moves to the inner vertical groove 721 to continue to move upward. At this time, the guide column 73 cooperates with the sliding block 6324 to control the vertical rod 6325 to move toward the carrier plate 621. At this time, the rack 6326 on the surface of the vertical rod 6325 is meshed with the gear ring 6321 on the surface of the carrier plate 621. When the vertical rod 6325 drives the rack 6326 to move upward, the rack 6326 and the gear ring 6321 are meshed and driven to drive the carrier plate 621 to rotate.

[0047] After the control plate 6317 rises to the limit height, the bearing plate 3 continues to move upward, so that the control plate 6317 and the magnetic plate 6318 are separated from each other, and the control plate 6317 falls to the surface of the workbench 1. After the bearing plate 621 rotates 180 degrees, the rack 6326 that continues to move upward is separated from the gear ring 6321, and the extrusion spring 5312 applies thrust to the clamping column 6313, and the clamping column 6313 is inserted into the clamping hole 6314 on the surface of the bearing plate 621 again, and the bearing plate 621 is fixed again. The two sets of clamps 61 and the bearing body are kept in a horizontal state in the processing cavity 13 again. At this time, the bearing plate 3 drives the grinder 5 to move downward again, and the grinding disc 51 can efficiently grind the end face of the upper surface of the bearing body. After the grinding is completed, the position of the clamp 61 is adjusted, and the grinding bearing body can be conveniently removed.

[0048] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
