Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, specifically to a passivation treatment device for motor bearings. Background Technology

[0002] Bearings have a long history, evolving from early linear motion bearings to modern rolling bearings, with their structure and function continuously improving. Scientists and engineers such as Galileo, Vallo, and Worth made significant contributions to the development of ball bearings. With the continuous advancement of industrial technology, the design, manufacturing, and application levels of bearings have also been significantly improved. Bearings are widely used in various mechanical equipment, such as wine and beverage equipment, pharmaceutical equipment, crushing machinery, biotechnology industrial equipment, mining equipment, printing and packaging machinery, food industrial equipment, plastic machinery, chemical fiber machinery, toys, clocks, electronic components, audio-visual equipment, power plants, gas turbines, motor manufacturing equipment, textile products, dyeing and finishing equipment, shoemaking equipment, tobacco machinery, and machine tools. In machine tool bearings, the performance of the spindle bearing directly affects key parameters such as the machine tool's speed and rotational accuracy. Bearings are an important component in motor applications. Before use, bearings require passivation treatment. However, existing bearing processing equipment often results in significant rust marks on the bearing surface during rust removal. Furthermore, the unclear thread lines on the bearing surface can cause jamming between the bearing's outer surface and the inner surface of the mounting structure during use. Therefore, this application proposes a passivation treatment device for motor bearings. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a passivation treatment device for motor bearings. It has the advantage of adding a rust scraping structure to remove rust from the outer surface of the bearing, thus solving the problem that existing bearing processing devices may have a large number of rust marks on the outer surface of the bearing during actual use, which affects the processing.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a passivation treatment device for motor bearings, comprising a base plate, a first base fixedly mounted on the top of the base plate, a first electric telescopic rod fixedly mounted on the top of the first base, a toothed plate fixedly sleeved on the outer surface of the first electric telescopic rod, a first support plate fixedly mounted on the top of the base plate, a first rotating rod rotatably connected to the outer surface of the first support plate, a gear fixedly sleeved at the end of the first rotating rod near the toothed plate, three support rods fixedly connected to the outer surface of the first rotating rod, bearings fixedly connected to the outer surfaces of the three support rods, grinding rods fixedly connected to the inner surfaces of the three bearings, a first baffle fixedly mounted on the outer surfaces of the three support rods, friction blocks fixedly mounted at the ends of the three grinding rods away from the bearings, a second base fixedly mounted on the top of the base plate, a second electric telescopic rod fixedly mounted on the top of the second base, a transmission plate fixedly sleeved on the outer surface of the second electric telescopic rod, and a threaded plate fixedly mounted at the end of the transmission plate away from the second electric telescopic rod.

[0005] Preferably, the outer surface of the gear meshes with the outer surface of the gear plate.

[0006] Preferably, the outer surfaces of the three first baffles are fixedly connected to the outer surface of the grinding rod by an arc-shaped elastic plate.

[0007] Preferably, a first support plate and a second support plate are fixedly installed on the top of the base plate, and the outer surfaces of the first support plate and the second support plate are fixedly connected by a limiting rod. The outer surface of the limiting rod is fixedly connected to the outer surface of the transmission plate by a rotating cylinder.

[0008] Preferably, a second support plate is fixedly installed on the top of the base plate. A through hole is opened on the outer surface of the second support plate. A first sleeve is fixedly installed on the inner surface of the through hole. A second sleeve is fixedly connected to the inner surface of the first sleeve through a connecting plate. Three through blocks are fixedly inserted on the outer surface of the second sleeve. Sliding pins are movably inserted on the inner surfaces of the three through blocks. A clamping arm is fixedly connected to the end of each of the three sliding pins away from the through blocks. A clamping plate is fixedly installed at the end of each of the three clamping arms away from the second sleeve. A connecting rope is fixedly connected to the opposite end of each of the three sliding pins. The end of each of the three connecting ropes away from the three sliding pins is fixedly connected through a second rotating rod. A handle is fixedly installed at the end of the second rotating rod away from the connecting rope.

[0009] Preferably, the inner surface of the first sleeve is provided with three limiting grooves, and the outer surface of the second sleeve is fixedly connected with three second baffles, the outer surfaces of the three second baffles being adapted to the inner surfaces of the three limiting grooves respectively.

[0010] Compared with the prior art, the present invention provides a passivation treatment device for bearings used in motors, which has the following advantages: 1. This motor uses a bearing passivation treatment device. The workpiece presses against the friction block, causing it to expand outwards. The force on the friction block is transmitted to the inside of the grinding rod, causing the grinding rod to tighten towards the first baffle. Through the force applied by the arc-shaped elastic plate, the workpiece and the outer surface of the grinding rod are completely fitted together. The output end of the first electric telescopic rod drives the toothed plate to reciprocate, causing the toothed plate to drive the gear to rotate the first rotating rod. The gear then drives the first rotating rod to rotate along the center of the first support plate, causing the first rotating rod to drive the grinding rod to remove rust and grind the workpiece. Subsequently, the second electric telescopic rod drives the rotating cylinder to reciprocate along the outer surface of the limiting rod via the transmission plate. This causes the transmission plate to drive the threaded plate to perform grooving operations on the outer surface of the workpiece. This adds a rust scraping structure and a thread opening structure, solving the problem in existing bearing processing devices where a large amount of rust on the outer surface of the bearing affects subsequent processing.

[0011] 2. The motor uses a bearing passivation treatment device. By rotating the throttle, the second rotating rod is driven to rotate. During the rotation of the second rotating rod, the connecting rope is wound around the outer surface of the second rotating rod. Then, the connecting rope drives the sliding column to retract inward along the through block, which in turn drives the clamping arm to retract inward. At this time, the clamping arm drives the clamping plate to clamp the workpiece. Then, the throttle is pushed inward, which drives the second rotating rod to move forward. During the forward movement of the second rotating rod, the second baffle gradually fits into the inner surface of the limiting groove, thereby limiting the workpiece. The stepless size adjustment structure is added to adapt to the processing of bearings of different specifications. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figure 1-7 The system includes a base plate 1, a first base 2 fixedly mounted on the top of the base plate 1, a first electric telescopic rod 3 fixedly mounted on the top of the first base 2, a toothed plate 4 fixedly fitted on the outer surface of the first electric telescopic rod 3, a first support plate 5 fixedly mounted on the top of the base plate 1, a first rotating rod 6 rotatably connected to the outer surface of the first support plate 5, a gear 7 fixedly fitted on the end of the first rotating rod 6 near the toothed plate 4, three support rods 18 fixedly connected to the outer surface of the first rotating rod 6, bearings 21 fixedly connected to the outer surface of each of the three support rods 18, grinding rods 23 fixedly connected to the inner surface of each of the three bearings 21, a first baffle 19 fixedly mounted on the outer surface of each of the three support rods 18, friction blocks 20 fixedly mounted on the end of each of the three grinding rods 23 away from the bearings 21, a second base 8 fixedly mounted on the top of the base plate 1, a second electric telescopic rod 9 fixedly mounted on the top of the second base 8, a transmission plate 15 fixedly fitted on the outer surface of the second electric telescopic rod 9, and a threaded plate 16 fixedly mounted on the end of the transmission plate 15 away from the second electric telescopic rod 9.

[0016] Specifically, the outer surface of gear 7 meshes with the outer surface of gear plate 4.

[0017] According to the above technical solution, the first electric telescopic rod 3 can drive the toothed plate 4 to reciprocate along the outer surface of the gear 7, thereby driving the gear 7 to rotate.

[0018] Specifically, the outer surfaces of the three first baffles 19 are fixedly connected to the outer surface of the grinding rod 23 by arc-shaped elastic plates 22.

[0019] According to the above technical solution, the angle formed by the three grinding rods 23 can be adjusted by the arc-shaped elastic plate 22 in conjunction with the bearing 21, thereby adapting to more different types of metal parts.

[0020] Specifically, a first support plate 11 and a second support plate 12 are fixedly installed on the top of the base plate 1. The outer surfaces of the first support plate 11 and the second support plate 12 are fixedly connected by a limiting rod 14. The outer surface of the limiting rod 14 is fixedly connected to the outer surface of the transmission plate 15 by a rotating cylinder 13.

[0021] According to the above technical solution, the second electric telescopic rod 9 can drive the rotating drum 13 to slide back and forth along the outer surface of the limiting rod 14 through the transmission plate 15, thereby enabling the transmission plate 15 to drive the threaded plate 16 to perform grooving operations on the outer surface of the workpiece.

[0022] Specifically, a second support plate 10 is fixedly installed on the top of the base plate 1. A through hole 17 is opened on the outer surface of the second support plate 10. A first sleeve 26 is fixedly installed on the inner surface of the through hole 17. A second sleeve 27 is fixedly connected to the inner surface of the first sleeve 26 through a connecting plate 28. Three through blocks 32 are fixedly inserted on the outer surface of the second sleeve 27. Sliding columns 31 are movably inserted on the inner surface of the three through blocks 32. A clamping arm 29 is fixedly connected to the end of each of the three sliding columns 31 away from the through blocks 32. A clamping plate 33 is fixedly installed at the end of each of the three clamping arms 29 away from the second sleeve 27. A connecting rope 34 is fixedly connected to the opposite end of each of the three sliding columns 31. The end of each of the three connecting ropes 34 away from the three sliding columns 31 is fixedly connected through a second rotating rod 25. A handle 24 is fixedly installed at the end of the second rotating rod 25 away from the connecting rope 34.

[0023] According to the above technical solution, the connecting rope 34 can be pulled by the second rotating rod 25 to pull the sliding column 31 inward along the inner surface of the through block 32, thereby causing the clamping arm 29 to retract inward along the outer surface of the first sleeve 26. At this time, the clamping arm 29 drives the clamping plate 33 to clamp the workpiece to be processed.

[0024] Specifically, the inner surface of the first sleeve 26 is provided with three limiting grooves 30, and the outer surface of the second sleeve 27 is fixedly connected with three second baffles 35, the outer surfaces of the three second baffles 35 being adapted to the inner surfaces of the three limiting grooves 30 respectively.

[0025] According to the above technical solution, the second rotating rod 25 can be driven by the throttle 24 to move downward along the inner surface of the second sleeve 27 until the outer surface of the second baffle 35 is in contact with the inner surface of the limiting groove 30 and then stops.

[0026] In use, the workpiece presses against the friction block 20, causing it to expand outwards. The force on the friction block 20 is transmitted to the interior of the grinding rod 23, causing the grinding rod 23 to be compressed towards the first baffle 19. Through the force on the arc-shaped elastic plate 22, the workpiece is brought into complete contact with the outer surface of the grinding rod 23. The output end of the first electric telescopic rod 3 drives the toothed plate 4 to reciprocate, causing the toothed plate 4 to drive the gear 7 to rotate the first rotating rod 6. At this time, the gear 7 drives the first rotating rod 6 to rotate along the center of the first support plate 5, thus causing the first rotating rod 6 to drive the grinding rod 23. 3. Rust removal and grinding are performed on the workpiece. Then, the second electric telescopic rod 9 drives the rotating drum 13 to slide back and forth along the outer surface of the limit rod 14 through the transmission plate 15. This causes the transmission plate 15 to drive the threaded plate 16 to perform grooving on the outer surface of the workpiece. This adds a rust scraping structure and a thread opening structure, which solves the problem that in the actual use of the existing bearing processing device, when processing the outer surface of the bearing, there may be a lot of rust marks on the outer surface of the bearing and the thread lines on the outer surface of the bearing may be blurred, which may cause the outer surface of the bearing to jam with the inner surface of the installation structure during use. When the workpiece needs to be clamped, the second rotating rod 25 is rotated by turning the handle 24. During the rotation of the second rotating rod 25, the connecting rope 34 is wound around the outer surface of the second rotating rod 25. Then the connecting rope 34 drives the sliding column 31 to retract inward along the through block 32, thereby causing the sliding column 31 to drive the clamping arm 29 to retract inward. At this time, the clamping arm 29 drives the clamping plate 33 to clamp the workpiece. Then the handle 24 is pushed inward, and the handle 24 drives the second rotating rod 25 to move forward. During the forward movement of the second rotating rod 25, the second baffle 35 gradually fits into the inner surface of the limiting groove 30, thereby limiting the workpiece. The stepless size adjustment structure is added to adapt to the processing of bearings of different specifications.
