Description

Technical Field

[0001] The present invention relates to the technical field of oil pump rotor processing, and specifically to a method for processing an oil pump rotor. Background Art

[0002] Existing automotive transmission oil pumps generally use rotor pumps, which have the advantages of small pump body volume and compact structure. At the same time, since the fluid is axially inhaled, under the action of the centrifugal force of the fluid, it is beneficial for the inhaled fluid to fill the tooth spaces, and it is not easy to generate the "cavitation" phenomenon. Moreover, within a certain rotational speed range, the higher the rotational speed, the better the inhalation characteristics and the higher the volumetric efficiency. Therefore, rotor pumps are widely used as lubricating oil pumps for automobiles, motorcycles, etc.

[0003] During the manufacturing process of rotor pumps, since it is difficult to process the inner wall of the rotor pump by means of a cutting tool, a method of metal powder extrusion is adopted to manufacture the rotor. For example, in the processing technology of the oil pump rotor with the publication number CN111979496B, during the manufacturing process, metal powder is put into a mold, and then a press is used to compact the metal powder in the mold to manufacture the initial shape of the rotor. At this time, although the metal product has the shape of a metal part, due to the difficulty of making the iron powder inside the metal fuse with each other by means of physical extrusion and shaping, the metal part at this time is still very fragile and cannot be put into use. At this time, the metal part still needs to be baked at a high temperature, so as to make the iron atoms inside the metal part fuse with each other by using chemical factors and become more stable.

[0004] However, due to the presence of excess metal powder around the mold during the pressing process, when the pressed metal part is taken out, part of the metal powder will adhere to the surface. In the existing processing technology, there is a lack of a device for cleaning the metal powder on the surface of the metal part, and manual cleaning is likely to cause the metal powder to be inhaled into the body of the worker. Then, the metal powder on the surface of the metal part will enter the high-temperature furnace together for high-temperature baking, so that the metal powder will fuse on the surface of the metal part, affecting the surface smoothness of the metal part and the yield rate of the metal part.

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] Embodiment 1. Please refer to Figures 1 to 8 , and a method for processing an oil pump rotor provided in this embodiment is as follows:

[0046] According to the metal powder compacting and forming device 1, the metal powder is pressed into a metal part, and then the second motor 6 rotates to drive the equipment box 2 to move towards the metal part formed on the metal powder compacting and forming device 1;

[0047] Then, when the equipment box 2 moves to the position of the metal part, the electric push rod 21 is started to drive the first straight tooth row 23 and the second straight tooth row 26 to move together, thereby driving the sliding rod 28 to start the clamping assembly to clamp the metal part, and under the action of the pressure fixing assembly, no additional pressure is applied to the metal part after clamping;

[0048] After clamping the metal part, start the blower 18 to blow off the metal dust on the surface of the metal part with wind;

[0049] While the blower 18 is running, start the rotating motor 33 to drive the metal part to rotate, so as to clean the metal part more comprehensively;

[0050] During the process of clamping the metal part and cleaning the surface of the metal part, make the second motor 6 rotate in the reverse direction. Further, the equipment box 2 can slide on the surface of the mounting frame 4, and then the metal part is transported to the transport assembly 7 to be transported into the high-temperature furnace for sintering to increase the strength of the metal part.

[0051] Please refer to Figure 3 、 Figure 4 and Figure 5 , in this embodiment, the processing method of the oil pump rotor involves using the following equipment:

[0052] It includes a mounting frame 4. The lower end surface of the mounting frame 4 is fixedly connected with a support rod 8. A metal powder compacting and forming device 1 is arranged on the left side of the mounting frame 4. A transport assembly 7 is arranged on the right side of the mounting frame 4. An equipment box 2 is also arranged on the mounting frame 4;

[0053] The equipment box 2 is provided with a pressure fixing assembly, and the pressure fixing assembly includes:

[0054] A moving frame 27. The inner wall of the moving frame 27 is rotatably connected with a toothed ring 22. The right end of the moving frame 27 is fixedly connected with a moving plate 25. An electric push rod 21 is also arranged in the equipment box 2. The end of the moving plate 25 is fixedly connected with the output end of the electric push rod 21;

[0055] A first straight tooth row 23. The non-toothed surface of the first straight tooth row 23 is slidably connected with a first sliding frame 20. The end of the first sliding frame 20 is fixedly connected with the inner wall of the equipment box 2. The toothed surface of the first straight tooth row 23 is meshed with the toothed surface of the toothed ring 22;

[0056] The straight-tooth row two 26 has a non-tooth surface of the straight-tooth row two 26 slidably connected with a sliding frame two 24. The end of the sliding frame two 24 is also fixedly connected to the inner wall of the equipment box 2. The tooth surface of the straight-tooth row two 26 is also meshed and connected with the tooth surface of the tooth ring 22. The end of the straight-tooth row two 26 is further fixedly connected with a sliding rod 28, and the surface of the sliding rod 28 slidably penetrates through the inner wall of the equipment box 2.

[0057] In this embodiment, when using this drill processing device to process the pressed metal part rotor, first start the motor two 6 to rotate and drive the equipment box 2 to move towards the metal part formed on the metal powder compacting device 1. When it moves to the position of the rotor, start the electric push rod 21. The electric push rod 21 moves to drive the moving plate 25 to move, thereby driving the moving frame 27 to move together, making the tooth ring 22 move, and thus driving the clamping assembly to clamp the rotor. Therefore, there are the following two motion states during the clamping process:

[0058] One: When there is no resistance on both the straight-tooth row one 23 and the straight-tooth row two 26, they will move together with the tooth ring 22.

[0059] Two: When the straight-tooth row two 26 clamps the rotor metal part, the straight-tooth row two 26 will be resisted during the movement and will not move. As a result, the tooth ring 22 will roll on the tooth surface of the straight-tooth row two 26, further causing the straight-tooth row one 23 to move.

[0060] The setting of this pressure fixing component makes the straight-tooth row two 26 not move with the tooth ring 22 after clamping, so that no additional pressure is generated on the metal part rotor after clamping, further solving the possibility that the metal part rotor formed by powder compacting is damaged due to excessive clamping pressure because its strength is insufficient. And this pressure fixing component can automatically clamp metal part rotors of different sizes, further improving the practicability of this device.

[0061] Embodiment two, on the basis of the above embodiment:

[0062] Please refer to Figure 3 、 Figure 6 and Figure 7 , in this embodiment, a clamping assembly is provided on the equipment box 2. The clamping assembly includes:

[0063] A double-sided straight-tooth row 30. The end of the double-sided straight-tooth row 30 is fixedly connected to the end of the sliding rod 28. The end of the double-sided straight-tooth row 30 is also slidably connected with a clamping frame mounting plate 31. The side of the mounting plate 31 is fixedly connected with a clamping frame 11. The end face of the clamping frame 11 is fixedly connected with a mounting rod 19. The other end of the mounting rod 19 is fixedly connected to the outer surface of the equipment box 2. A blower 18 is arranged on the upper end face of the clamping frame 11, and the output end of the blower 18 is fixedly connected with a collecting air duct 17.

[0064] The fan gear 29, the tooth surface of the fan gear 29 is meshed with the tooth surface of the double-sided spur gear row 30, the inner wall of the fan gear 29 is rotatably connected to the lower end surface of the mounting plate 31, the end of the fan gear 29 is also fixedly connected to a curved rod 1 44, the other end of the curved rod 1 44 is hinged to a clamping plate 32, the clamping plate 32, the end of the clamping plate 32 is also hinged to a curved rod 2 34, the other end of the curved rod 2 34 is hinged to the surface of the mounting plate 31, the side of the clamping plate 32 is fixedly connected to a dust cover 16, and the outer surface of the dust cover 16 is also rotatably connected to a clamping pad 12.

[0065] In this embodiment, the gear ring 22 drives the second spur gear row 26 to move, which drives the sliding rod 28 to move. The movement of the sliding rod 28 further drives the double-sided spur gear row 30 to move toward the device box 2, and then the double-sided spur gear row 30 drives the two fan gears 29 to deflect, thereby driving the first curved rod 44 and the second curved rod 34 to deflect. Through the joint deflection of the first curved rod 44 and the second curved rod 34, the two clamping plates 32 are driven to approach each other. After approaching, the clamping pad 12 can be further driven to clamp the metal part of the pressed blank, and then the blower 18 is started to blow off the dust on the surface of the metal part;

[0066] The setting of the clamping assembly replaces the traditional process of taking out the metal parts by hand by clamping the metal parts of the pressed blank, and moves the formed metal parts away from the drill on the metal powder pressed blank forming device 1, thereby reducing the metal powder blown away during dust removal and being inhaled by the workers, further improving the safety of production personnel when producing and processing drills.

[0067] Embodiment 3, based on the above embodiment:

[0068] See also Figure 6 , Figure 7 and Figure 8 In this embodiment, a rotating assembly is provided on the equipment box 2, and the rotating assembly includes:

[0069] A fixed plate 36, the lower end surface of the fixed plate 36 is fixedly connected to the upper end surface of the clamping plate 32, the upper end of the fixed plate 36 is rotatably connected to a rotating column, a rotating motor 33 is also provided on the lower end surface of the fixed plate 36, the output end of the rotating motor 33 is belt-driven with the surface of the rotating column through a belt, a cam 37 is also fixedly connected to the end surface of the rotating column, a sliding column 38 is fixedly connected to the end surface of the cam 37 away from the fixed plate 36, and a sliding frame 39 is slidably connected to the surface of the sliding column 38;

[0070] The straight-tooth row three 35 has its side surface fixedly connected to the side surface of the sliding frame 39. A sliding groove 40 is provided on the side surface of the straight-tooth row three 35 facing away from the sliding frame 39. The groove wall of the sliding groove 40 is slidably connected to a limiting frame 41. The lower end of the limiting frame 41 is fixedly connected to the side surface of the clamping plate 32. The tooth surface of the straight-tooth row three 35 is meshed with a second tooth ring 42. A second rotating rod 43 is fixedly connected to the inner wall of the second tooth ring 42. The surface of the second rotating rod 43 rotatably penetrates through the side surface of the clamping plate 32. The end surface of the second rotating rod 43 away from the second tooth ring 42 is fixedly connected to the end surface of the clamping pad 12.

[0071] In this embodiment, after clamping the metal part rotor, start the rotating motor 33 to drive the rotating column to rotate. The rotation of the rotating column further drives the cam 37 to rotate. The rotation of the cam 37 further drives the sliding column 38 to slide within the sliding frame 39, thereby driving the sliding frame 39 to reciprocate, so that the straight-tooth row three 35 moves on the limiting frame 41, thereby driving the second tooth ring 42 to rotate, causing the second rotating rod 43 to rotate, and enabling the clamping pad 12 to drive the metal part rotor to rotate.

[0072] The setting of this rotating assembly enables the clamping pad 12 to drive the metal part rotor to rotate during the clamping process, so that the wind generated by the blower 18 can blow on different surfaces of the metal part rotor to remove the attached metal powder, and further clean the attached metal powder on the surface more comprehensively.

[0073] Furthermore, please refer to Figure 2 and Figure 3 , in this embodiment, a moving assembly is further provided on the equipment box 2. The moving assembly includes:

[0074] A second sliding frame 5 has its outer lower surface fixedly connected to the inner upper surface of the mounting frame 4. A second motor 6 is further provided inside the mounting frame 4. The output end of the second motor 6 rotatably penetrates through the side surface of the second sliding frame 5, and the end surface of the output end of the second motor 6 is fixedly connected to a threaded rod 9.

The lower surface of the straight-tooth row four 15 is fixedly connected to the upper surface of the mounting frame 4. A guide plate 3 is further provided on the upper surface of the mounting frame 4.

[0076] In this embodiment, starting the second motor 6 can drive the threaded rod 9 to rotate. The rotation of the threaded rod 9 causes the sliding block 10 to slide within the second sliding frame 5, further driving the connecting column 14 to move. During the movement of the connecting column 14, the third toothed ring 13 fixedly connected thereto will also move. When the third toothed ring 13 meshes with the fourth straight toothed row 15 during movement, it will rotate, thereby driving the equipment box 2 to rotate 180 degrees, so as to achieve the purpose of transporting the metal parts on the metal powder compacting and forming device to the transportation component 7 for transportation to the high-temperature furnace for sintering.

[0077] The setting of this moving component automatically transports the metal parts on the metal powder compacting and forming device to the transportation component 7 for transportation to the high-temperature furnace for sintering, thereby improving the automation degree of this device and further enhancing the practicality during the processing of this rotor.

[0078] Working principle: When using this method for processing an oil pump rotor, it has the following steps:

[0079] S1: According to the metal powder compacting and forming device 1, the metal powder is pressed into a metal part. Then, the second motor 6 rotates to drive the equipment box 2 to move towards the metal part formed on the metal powder compacting and forming device 1.

[0080] S2: Then, when the equipment box 2 moves to the position of the metal part, start the electric push rod 21 to drive the first straight toothed row 23 and the second straight toothed row 26 to move together, thereby driving the sliding rod 28 to start the clamping component to clamp the metal part. And under the action of the pressure fixing component, no additional pressure will be applied to the metal part after it is clamped.

[0081] S3: After clamping the metal part, start the blower 18 to blow the metal dust on the surface of the metal part with air.

[0082] S4: While the blower 18 is operating, start the rotating motor 33 to drive the metal part to rotate, so as to clean the metal part more comprehensively.
