Description

Technical Field

[0001] The present invention relates to the technical field of polishing devices, and particularly relates to a polishing device and a polishing process for machining mechanical transmission parts. Background Art

[0002] As is well known, mechanical transmission refers to the process of transmitting power and motion by mechanical means. It mainly relies on the friction between machine parts or the meshing between the driving part and the driven part to transmit power or motion. Mechanical transmission is widely used in mechanical engineering. Therefore, the demand for mechanical transmission parts that make up mechanical transmission is also very large. Most mechanical transmission parts will be polished during the preparation process. Therefore, we propose a polishing device and a polishing process for machining mechanical transmission parts to achieve high-efficiency polishing treatment of mechanical transmission parts.

[0003] After retrieval, the patent with the Chinese patent publication number CN208005429U discloses a polishing device for machining mechanical transmission parts. It is generally described as including a device body. The device body is an L-shaped structure. A moving seat, a sliding seat and a motor are installed on the top of the device body. A hydraulic cylinder is fixedly connected between one side of the moving seat and the device body. A fixed disk is provided on the other side of the moving seat. A plurality of threaded holes are formed on the surface of the fixed disk, and threaded columns are rotatably connected inside the threaded holes. A connection hole is formed in the middle position on one side of the fixed disk, and spring cavities are provided on both sides of the connection hole. One side of each spring cavity is communicated with the threaded hole, and the other side of each spring cavity is communicated with the connection hole. A gear groove is formed on the top surface of the sliding seat, and a support frame is fixedly installed on one side of the top of the sliding seat. When in use, the polishing wheel rotation switch and the motor are started, the fixed disk starts to rotate, and the polishing wheel starts to polish the parts. The patent with the Chinese patent publication number CN110270901B discloses a gear polishing machine for gear manufacturing. It is generally described as including foot cups, a base, a driving motor, a rotating device, a workbench and a clamping device. The base is an inwardly concave circular structure and foot cups are installed at the bottom. The driving motor is installed on the outer circle of the base and is in transmission cooperation with the rotating device. A workbench is provided in the middle of the base, and a clamping device is fixedly connected in the middle of the workbench. When in use, the moving seat drives the polishing device to approach the gear on the clamping shaft, the rotating motor makes the polishing wheel rotate at high speed, and the six groups of polishing devices on the workbench move synchronously between the teeth of the gear to polish the tooth surface.

[0004] Analyzing the above-mentioned previous prior art solution in combination with the corresponding attached drawings, it can be clearly judged that the area that the polishing wheel can polish at one time is limited. To achieve full-coverage polishing of the part, the polishing wheel needs to move to different areas of the part to form a comprehensive polishing operation of the part. Although the latter prior art solution mentioned above introduces multiple polishing wheels, considering that there are a large number of teeth on the gear, it is obvious that the number of polishing wheels cannot be set equal to the number of teeth. In this way, the polishing wheel needs to polish one tooth first and then polish the next tooth, that is, multiple teeth also need to be polished in sequence. Therefore, the polishing efficiency of the above two technical solutions needs to be further improved, and both of them complete the polishing operation by the rotation of the polishing wheel. Therefore, the movement direction is single, and at the same time, the polishing wheel is also consumed during the polishing process. Therefore, the stability of the polishing quality also needs to be further improved. Summary of the Invention

Through the cooperation of the electromagnets 10 and the iron sand, the distribution control and driving of the iron sand in the alternating mounting cylinders 2 are formed to correspond to the areas to be polished of the mechanical transmission parts, so as to realize the polishing operation with a large coverage rate of the mechanical transmission parts. Moreover, multiple mechanical transmission parts can be synchronously polished at one time, and the polishing efficiency is relatively high. The two clamping structures both include driven shaft frames 32, driving shaft sleeves 33 and variable-frequency motors 34. The two variable-frequency motors 34 are respectively installed on the two alternating mounting cylinders 2, the two driven shaft frames 32 are respectively rotatably connected in the two alternating mounting cylinders 2, the two driving shaft sleeves 33 are respectively rotatably connected in the two alternating mounting cylinders 2, and the output shafts of the two variable-frequency motors 34 are respectively connected to the two driving shaft sleeves 33.

Through the matching of the clamping structures, the auxiliary positioning of multiple mechanical transmission parts to be polished in the alternating mounting cylinders 2 can be realized, which is convenient for the subsequent polishing operation of the mechanical transmission parts and also convenient for the synchronous polishing operation of multiple mechanical transmission parts. One end of the double limiting spring 36 is fixedly connected to an insertion rotating connecting block 43, the other end of the double limiting spring 36 is fixedly connected to a placement shaft frame 44, and a lining rotating ring 45 is connected to the outside of the placement shaft frame 44.The inner lining swivel ring 45 is rotatably connected within the alternating mounting cylinder 2.

[0047] The servo motor 4, the electromagnet 10, and the variable frequency motor 34 in this embodiment are all conventional devices well-known to those skilled in the art and purchased on the market. In the present invention, we only use them without improving their structures and functions. Their setting methods, installation methods, and electrical connection methods can be debugged and operated by those skilled in the art as long as they follow the requirements of their user manuals, and will not be elaborated here.

[0048] In summary, the working principle of the polishing device and the polishing process for machining mechanical transmission parts is as follows. Before use, first install a control circuit and a controller for the servo motor 4, the electromagnet 10, and the variable-frequency motor 34. Through the controller combined with the control circuit, the coordinated operation control of the servo motor 4, the electromagnet 10, and the variable-frequency motor 34 can be achieved. Since the power-on operation of the servo motor 4 will drive the rotation of the driving bevel gear 48, under the action of the meshing transmission of the two driven bevel gears 49 with the driving bevel gear 48, the rotation of the driving bevel gear 48 can drive the rotation of the two stepped shaft cylinders 3, and the rotation of the stepped shaft cylinder 3 drives the rotation of the alternately installed cylinder 2 connected thereto. Since the driven bevel gears 49 are distributed on both sides of the driving bevel gear 48, the rotation directions of the two stepped shaft cylinders 3 are opposite. Therefore, by operating the servo motor 4, the alternately installed cylinders 2 can be alternately and repeatedly raised and lowered, that is, when one of the two alternately installed cylinders 2 rotates and rises, the other will rotate and fall, and when one of the two alternately installed cylinders 2 rotates and falls, the other will rotate and rise. And during the rotation of the stepped installation cylinder, the driving screw cylinder 18 will be driven to rotate synchronously. Since there is a threaded connection between the driving screw cylinder 18 and the traction slide bar 17, and there is a sliding connection between the traction slide bar 17 and the main frame 1, the rotation of the driving screw cylinder 18 will cause the traction slide bar 17 to slide relative to the main frame 1. The sliding of the traction slide bar 17 relative to the main frame 1 will cause the position of the end ball frame 19 to change. During the movement of the end ball frame 19, the connecting spring 20 is elastically pulled. When the connecting spring 20 is pulled, the force is transmitted to the driving plate 21. The traction force borne by the driving plate 21 is respectively transmitted to the first sub-rope 23 and the second sub-rope 24 through the synchronous traction rope 22. Under the transmission action of the first sub-rope 23 and the second sub-rope 24, the corresponding traction force is transmitted to the first insertion frame 14 and the second insertion frame 15. Finally, the traction force borne by the first insertion frame 14 and the second insertion frame 15 acts on the linkage door 5. Due to the action of the reset tension spring 16, the linkage door 5 is in a closed state relative to the alternately installed cylinder 2. Therefore, in the process of the connecting spring 20 just starting to bear the tension given by the end ball frame 19, the linkage door 5 will not move relative to the alternately installed cylinder 2. As the rotation amplitude of the alternately installed cylinder 2 decreases, the movement amplitudes of the traction slide bar 17 and the end ball frame 19 also increase, resulting in an increase in the tension borne by the connecting spring 20. When the tension borne by the connecting spring 20 can overcome the elastic force of the corresponding two reset tension springs 16, the linkage door 5 will open relative to the alternately installed cylinder 2. Since both the first guiding frame 11 and the second guiding frame 12 are provided with a straight section and an arc section, during the opening process of the linkage door 5, the first insertion frame 14 will first slide across the straight section and then enter the arc section relative to the first guiding frame 11. Similarly, the second insertion frame 15 will first slide across the straight section and then enter the arc section relative to the second guiding frame 12, so as to ensure that during the entire opening process of the linkage door 5, it will first be pulled out relative to the alternately installed cylinder 2 and then rotate and open.Therefore, under the driving action of the rotating follower assembly, the linkage door 5 is opened as it falls along with the rotation of the alternating mounting cylinder 2.

[0049] Further, a mechanical transmission part to be polished is loaded into one of the alternating mounting cylinders 2 that rotates and falls, and an auxiliary positioning of the mechanical transmission part to be polished placed in the alternating mounting cylinder 2 is formed through a clamping structure. The positioning steps of the clamping structure are as follows: First, the insertion drive frame 35 is pushed upward relative to the driven shaft frame 32 so that the double limit spring 36 rotates and rises. During this process, the double limit spring 36 will be gradually compressed until it is compressed to the shortest length, and then the double limit spring 36 will rotate and rise. After that, the insertion drive frame 35 will be pushed upward by the double limit spring 36 so that the insertion drive frame 35 maintains a completely pulled-out state relative to the driven shaft frame 32. After that, a plurality of mechanical transmission parts to be polished are placed in the gap between the insertion drive frame 35 and the driven shaft frame 32, and the relative position between the mechanical transmission parts and the driven shaft frame 32 is adjusted so that the driven shaft frame 32 is inserted into the intermediate shaft hole on the mechanical transmission parts. Then, the insertion drive frame 35 is adjusted to be inserted into the driven shaft frame 32 again. During the insertion process, manual auxiliary height adjustment is performed on the mechanical transmission parts sleeved on the driven shaft frame 32 so that the plurality of mechanical transmission parts respectively have appropriate heights with respect to the plurality of round head frames 41. To facilitate the clamping and positioning of the plurality of mechanical transmission parts, a spacer cylinder can be provided between two adjacent mechanical transmission parts to facilitate the height correspondence between the plurality of mechanical transmission parts and the plurality of round head frames 41 with different heights. Then, the insertion drive frame 35 is inserted into the driven shaft frame 32 completely again so that the plurality of first clamping frames 37 and the plurality of second clamping frames 38 are synchronously pushed and tightened to achieve the tightening and positioning of the plurality of mechanical transmission parts to be polished. After that, the servo motor 4 works again to realize the rotation and rising of the alternating mounting cylinder 2 on which the mechanical transmission parts have been installed. During the rotation and rising process, the traction slide rod 17 will slide and retract relative to the main frame 1. During this process, the pulling force of the end ball frame 19 on the connecting spring 20 decreases, and under the action of the corresponding return tension spring 16, the linkage door 5 is reset and closed relative to the alternating mounting cylinder 2. During the closing process of the linkage door 5, the first insertion frame 14 will first slide across an arc segment and then enter a straight segment relative to the first guiding frame 11. Similarly, the second insertion frame 15 will first slide across an arc segment and then enter a straight segment relative to the second guiding frame 12, realizing the rotational alignment of the linkage door 5 relative to the alternating mounting cylinder 2 and then the insertion and closing relative to the alternating mounting cylinder 2, that is, the servo motor 4 operates to control the alternating mounting cylinder 2 in the originally raised state to rotate and fall, and at the same time control the alternating mounting cylinder 2 in the fallen state to rotate and rise. The linkage door 5 corresponding to the rotating and rising alternating mounting cylinder 2 will rotate and close.

[0050] Further, energize the electromagnets 10 in the fixed frame 8 corresponding to the alternating mounting cylinder 2 for the horizontal posture and the electromagnets 10 in the sliding frame 9, so that the energized electromagnets 10 generate an electromagnetic field acting on the iron sand. Under the action of the electromagnetic field, the iron sand will form a lining around the inner side arm corresponding to the alternating mounting cylinder 2, so that the iron sand corresponds to the mechanical transmission parts to be polished. Control the current direction of the electromagnets 10 in the sliding frame 9 adjacent to the fixed frame 8. At the same time, taking the sliding frame 9 adjacent to the fixed frame 8 as a reference, select the electromagnets 10 in every other sliding frame 9 and control the direction of the current passing through them to achieve magnetic regulation of the relative distance of multiple sliding frames 9. The principle of magnetic regulation is as shown in the appendix Figure 17 shown. In this process, when the magnetic pole directions of the opposite sides between two adjacent electromagnets 10 on the left and right are opposite, a mutually magnetic attractive force will appear between the two electromagnets 10. At this time, the fixed frame 8 and multiple sliding frames 9 will be synchronously closed and stored, as shown in the upper side figure in the appendix Figure 17 shown. When the magnetic pole directions of the opposite sides between two adjacent electromagnets 10 on the left and right are the same, a mutually magnetic repulsive force will appear between the two electromagnets 10. At this time, the fixed frame 8 and multiple sliding frames 9 will be synchronously driven away, as shown in the appendix Figure 17As shown in the lower-side figure, through the alternating presentation of the two forms of synchronous approaching and receiving and synchronous moving away and driving described above, the reciprocating movement drive of the iron sand in the alternating installation cylinder 2 can be realized, so as to form a polishing operation on the mechanical transmission parts. Since the iron sand is arranged in a lining surrounding manner that fits the inner side arm of the alternating installation cylinder 2, the polishing coverage of the tooth surface of the gear teeth is relatively good. And when the alternating installation cylinder 2 rotates and falls, the iron sand will enter the storage box 6 under the action of its own gravity to form storage. When the alternating installation cylinder 2 rotates and rises, the iron sand in the storage box 6 will enter the alternating installation cylinder 2 again under the action of gravity. During the process of the alternating installation cylinder 2 rotating from the horizontal posture to the vertical posture, since the linkage door 5 does not open at the initial stage of rotation, that is, when the traction force borne by the connecting spring 20 cannot overcome the elastic force of the return spring 16 to cause the return spring 16 to form elastic deformation, the linkage door 5 has a relatively stable closed posture relative to the alternating installation cylinder 2 to which it is correspondingly installed. Therefore, it can control the iron sand in the alternating installation cylinder 2 to first fall into the storage box 6 before the linkage door 5 is opened, avoiding the spilling of the iron sand during the opening process of the linkage door 5. Since the alternating installation cylinder 2 needs to rotate and fall after each polishing is completed, the iron sand will fall into the storage box 6 from the alternating installation cylinder 2 after each polishing is completed. After the alternating installation cylinder 2 rotates and rises again, the iron sand will return to the alternating installation cylinder 2 from the storage box 6. Therefore, a new layout of the iron sand in the alternating installation cylinder 2 is formed for each polishing operation. This can not only transfer the powder under polishing, but also screen the iron sand to ensure the polishing effect and efficiency, which is equivalent to replacing the polishing wheel in the two sets of solutions in the background technology. And during the polishing process, by starting the variable-frequency motor 34, the variable-frequency motor 34 works to realize the rotational drive of the drive shaft sleeve 33. The rotation of the drive shaft sleeve 33 drives the driven shaft frame 32 to rotate through the inserted drive frame 35. The rotation of the driven shaft frame 32 drives the multiple mechanical transmission parts sleeved thereon to rotate, so as to enrich the relative movement forms between the mechanical transmission parts and the iron sand during the polishing process, and further improve the polishing coverage rate and polishing effect of the mechanical transmission parts.
