Description

Technical Field

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

[0002] As we all know, 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 active part and the driven part to transmit power or motion. Mechanical transmission is widely used in mechanical engineering, so the demand for mechanical transmission parts that constitute mechanical transmission is also very large. Most of the mechanical transmission parts are polished during the preparation process. Therefore, we proposed a polishing device and polishing process for mechanical transmission parts processing to achieve high-efficiency polishing of mechanical transmission parts.

[0003] After searching, the Chinese patent publication number CN208005429U discloses a polishing device for machining mechanical transmission parts, which is roughly described as including a device body, which is an L-shaped structure, a movable 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 movable seat and the device body, a fixed disk is provided on the other side of the movable seat, a plurality of threaded holes are opened on the surface of the fixed disk, and threaded columns are rotatably connected inside the threaded holes, a connecting hole is opened in the middle position of one side of the fixed disk, and spring cavities are provided on both sides of the connecting hole, one side of the spring cavity is connected to the threaded hole, and the other side of the spring cavity is connected to the connecting hole, a gear groove is opened 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 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 Chinese patent announcement number CN110270901B discloses a gear polishing machine for gear manufacturing, which is roughly described as including a foot cup, a base, a driving motor, a rotating device, a workbench, and a clamping device. The base is a concave circular structure and a foot cup is installed at the bottom. The driving motor is installed on the outer circle of the base and cooperates with the rotating device in transmission. 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, and the rotating motor makes the polishing wheel rotate at high speed. The six groups of polishing devices on the workbench move synchronously between the gear teeth to polish the tooth surface.

[0004] By analyzing the above-mentioned first prior art scheme in combination with the corresponding drawings, it can be obviously judged that the area that the polishing wheel can correspond to for a single polishing is limited. To achieve full coverage polishing of the parts, the polishing wheel needs to be moved to different areas of the parts to form a comprehensive polishing operation of the parts. Although the above-mentioned second prior art scheme introduces multiple polishing wheels, considering that the gear contains a large number of gear teeth, it is obviously impossible to achieve the equal setting of the number of polishing wheels and the number of gear teeth. In this way, the polishing wheel needs to polish one gear tooth first, and then polish the next gear tooth, that is, multiple gear teeth also need to be polished in sequence. Therefore, the polishing efficiency of the above-mentioned two technical schemes needs to be further improved, and both of them complete the polishing operation by rotating the polishing wheel, so the movement direction is single, and the polishing wheel is also consumed along with the polishing, so the stability of the polishing quality needs to be further improved.

[0026] The servo motor 4, electromagnet 10 and variable frequency motor 34 in this embodiment are all conventional devices purchased on the market and known to those skilled in the art. In the present invention, we only use them without improving their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged and operated according to the requirements of their instruction manual, and will not be described in detail here.

[0027] In summary, the working principle of the polishing device and polishing process for machining mechanical transmission parts is that, before use, a control circuit and a controller are first installed for the servo motor 4, the electromagnet 10 and the variable frequency motor 34. The controller combined with the control circuit can realize the coordinated operation control of the servo motor 4, the electromagnet 10 and the variable frequency motor 34. Since the servo motor 4 is powered on, the driving bevel gear 48 can be driven to rotate. Under the action of the meshing transmission of the two driven bevel gears 49 and the driving bevel gear 48, the rotation of the driving bevel gear 48 can realize the rotation drive of the two stepped shaft cylinders 3, and the rotation of the stepped shaft cylinder 3 realizes the rotation drive 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 two The rotation directions of the stepped shaft cylinder 3 are opposite, so the operation of the servo motor 4 can realize the alternating and repeated lifting and lowering of the two alternately installed cylinders 2, 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 form a synchronous rotation. Since a threaded connection is provided between the driving screw cylinder 18 and the traction slide rod 17, and a sliding connection is provided between the traction slide rod 17 and the main frame 1, the rotation of the driving screw cylinder 18 will cause the traction slide rod 17 to slide relative to the main frame 1, and the sliding of the traction slide rod 17 relative to the main frame 1 will cause the end ball rack 19 to change its position, and the end ball rack 19 will change its position during the movement. During the process, elastic traction is formed on the connecting spring 20, and the connecting spring 20 is pulled to transmit the force to the driving plate 21. The traction force borne by the driving plate 21 is transmitted to the first branch rope 23 and the second branch rope 24 respectively through the synchronous traction rope 22. Under the transmission action of the first branch rope 23 and the second branch rope 24, the corresponding traction force will be 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 will act on the linkage door 5. Due to the action of the reset tension spring 16, the linkage door 5 will be in a closed state relative to the alternate installation cylinder 2. Therefore, when the connecting spring 20 just begins to bear the pulling force given by the end ball rack 19, the linkage door 5 will not form a position movement relative to the alternate installation cylinder 2, and with the alternating installation As the rotation amplitude of the mounting tube 2 increases, the movement amplitude of the traction slide bar 17 and the end ball rack 19 also increases, which in turn increases 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 be opened relative to the alternate mounting tube 2. Since the first guide frame 11 and the second guide frame 12 are both provided with straight line segments and arc segments, during the opening process of the linkage door 5, the first insertion rack 14 will first pass through the straight line segment and then enter the arc segment relative to the first guide frame 11. Similarly, the second insertion rack 15 will first pass through the straight line segment and then enter the arc segment relative to the second guide frame 12. In this way, it is ensured that during the entire process of opening the linkage door 5, it will first be pulled out relative to the alternate mounting tube 2 and then rotated to open.Therefore, under the driving action of the rotating follower assembly, the linkage door 5 opens along with the rotation and fall of the alternating installation cylinder 2.

[0028] Furthermore, in order to load the mechanical transmission parts to be polished into the rotating and falling alternating installation cylinder 2, and to form auxiliary positioning of the mechanical transmission parts to be polished placed in the alternating installation cylinder 2 through the clamping structure, the positioning step of the clamping structure is to first push the insertion drive frame 35 upward relative to the driven shaft frame 32 to make the double limit spring 36 rotate and rise. During this process, the double limit spring 36 will be gradually compressed until it is compressed to the shortest length, and the double limit spring 36 will rotate and rise. Thereafter, the insertion drive frame 35 will be pushed upward by the double limit spring 36 to make the insertion drive frame 35 relative to the driven shaft frame 32 form a fully pulled out state. After that, multiple mechanical transmission parts to be polished are inserted into the gap between the insertion drive frame 35 and the driven shaft frame 32, and the relative positions of the mechanical transmission parts and the driven shaft frame 32 are 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 and inserted into the driven shaft frame 32 again. During the insertion process, the mechanical transmission parts sleeved on the driven shaft frame 32 are manually adjusted to auxiliary heights so that the multiple mechanical transmission parts are respectively at appropriate heights with the multiple round head frames 41. In order to facilitate the clamping and positioning of the multiple mechanical transmission parts, a cushion cylinder can be set between two adjacent mechanical transmission parts to It is convenient for multiple mechanical transmission parts to form height correspondence with multiple round head frames 41 with different heights, and then the insertion drive frame 35 is completely inserted into the driven shaft frame 32 again, so that the multiple first clamping frames 37 and the multiple second clamping frames 38 form synchronous pushing and tightening, so as to realize the tightening and positioning of multiple mechanical transmission parts to be polished, and then the servo motor 4 is operated again to realize the rotation and lifting of the alternating installation cylinder 2 on which the mechanical transmission parts have been installed. During the rotation and lifting process, the traction slide bar 17 will slide relative to the main frame 1. During this process, the traction force of the end ball frame 19 on the connecting spring 20 is reduced, and under the action of the corresponding reset tension spring 16 Under, the linkage door 5 is reset and closed relative to the alternating installation tube 2. During the closing process of the linkage door 5, the first insertion frame 14 will first cross the arc segment and then enter the straight segment relative to the first guide frame 11. Similarly, the second insertion frame 15 will first cross the arc segment and then enter the straight segment relative to the second guide frame 12, so that the linkage door 5 is first rotated and aligned relative to the alternating installation tube 2 and then inserted and closed relative to the alternating installation tube 2. That is, the servo motor 4 is running to control the alternating installation tube 2 in the originally raised state to rotate and fall, and at the same time control the alternating installation tube 2 in the fallen state to rotate and rise, and the linkage door 5 corresponding to the rotating and rising alternating installation tube 2 will rotate and close.

[0029] Furthermore, the electromagnet 10 in the fixed frame 8 and the electromagnet 10 in the sliding frame 9 corresponding to the alternating installation cylinder 2 in the horizontal posture are controlled to be energized, so that the electromagnet 10 is energized to generate an electromagnetic field acting on the iron sand. Under the action of the electromagnetic field, the iron sand will form an inner lining surrounding arrangement that fits the inner arm relative to the alternating installation cylinder 2, so that the iron sand corresponds to the mechanical transmission part to be polished, and the current direction of the electromagnet 10 in the sliding frame 9 adjacent to the fixed frame 8 is controlled. At the same time, with the sliding frame 9 adjacent to the fixed frame 8 as a reference, the electromagnet 10 in the sliding frame 9 that jumps one by one is selected and the direction of the current passed therein is controlled, so as to realize the magnetic regulation of the relative distance of multiple sliding frames 9. The principle of magnetic regulation is as shown in the attached Fig.17 As shown in FIG. 1 , during this process, when the magnetic poles of the two adjacent electromagnets 10 on the left and right sides are in opposite directions, the two electromagnets 10 will have a mutual magnetic attraction force, and at this time, the fixed frame 8 and the plurality of sliding frames 9 will be synchronously brought together and stored, as shown in FIG. Fig.17 As shown in the upper figure, when the magnetic poles of the opposite sides of the two adjacent electromagnets 10 are in the same direction, the two electromagnets 10 present a mutual magnetic repulsion force, and at this time, the fixed frame 8 and the plurality of sliding frames 9 are synchronously driven away, as shown in the attached figure. Fig.17As shown in the lower figure, through the alternating presentation of the two forms of synchronous approaching storage and synchronous moving away driving mentioned above, the reciprocating movement drive of the iron sand in the alternating installation cylinder 2 can be realized, thereby forming a polishing operation for the mechanical transmission parts. Since the iron sand is arranged around the inner lining of the inner arm of the alternating installation cylinder 2, the polishing coverage of the wheel surface of the gear teeth is good, and when the alternating installation cylinder 2 rotates and falls, the iron sand will enter the storage box 6 for storage under the action of its own gravity, and 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. In the process of the alternating installation cylinder 2 rotating from the horizontal posture to the vertical posture, since the linkage door 5 is not opened in the initial stage of rotation, that is, the traction force borne by the connecting spring 20 cannot overcome the elastic force of the reset tension spring 16 and causes the reset tension spring 16 to form elastic deformation, the linkage door 5 has a relatively stable closed posture relative to the corresponding alternating installation cylinder 2, so the iron sand in the alternating installation cylinder 2 can be controlled to fall into the storage box 6 first to realize the linkage door 5. Open to avoid the spillage of iron sand during the opening 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, each polishing operation will form a new layout of the iron sand in the alternating installation cylinder 2. 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 the replacement of the polishing wheel of the two sets of schemes in the background technology. In addition, during the polishing process, by starting the frequency conversion motor 34, the frequency conversion motor 34 is started to work to realize the rotation drive of the driving shaft sleeve 33. The driving shaft sleeve 33 rotates and drives the driven shaft frame 32 to rotate by inserting the driving frame 35. The driven shaft frame 32 rotates and drives the multiple mechanical transmission parts mounted thereon to rotate, so as to enrich the relative motion form between the mechanical transmission parts and the iron sand during the polishing process, and further improve the polishing coverage and polishing effect of the mechanical transmission parts.
