Description

Technical Field

[0001] The utility model relates to the technical field of workpiece hole processing, in particular to a honing device for a cycloid wheel crankshaft hole. Background Art

[0002] RV reducers are widely used in industrial robots, medical equipment and other fields due to their wide transmission ratio range, strong torsional rigidity and high transmission efficiency. RV reducers have a set of cycloid wheels, consisting of cycloid wheel A and cycloid wheel B. The two cycloid wheels are assembled by three crankshafts through needle bearings. The two cycloid wheels are respectively mounted on the two eccentric shafts of the crankshaft. When the reducer is running, the three crankshafts rotate simultaneously to drive the two cycloid wheels to swing. This requires that the three bearing holes of each cycloid wheel have very high precision and hardness, and the position accuracy of the two cycloid wheels is also required to be very high. Only in this way can the cycloid wheels run smoothly.

[0003] At present, most of the processing of cycloid wheels still uses internal grinding. Internal grinding is a general-purpose machine tool. For this kind of part with an inner hole that is not in the center and three holes on a part, it is difficult to make fixtures. Moreover, the roundness and cylindricity of the three holes after grinding do not meet the requirements. Secondly, the use of internal grinding has high requirements on the operator, low processing efficiency and high scrap rate.

[0043] like Figure 3 As shown, the rough honing unit 2 includes a mounting frame 201 and a top box 12 mounted on the top of the mounting frame 201. A honing rotary motor 14 is mounted on one end of the top box 12, and a honing rotary spindle 92 is provided through the other end of the top box 12. Pulleys are provided at the output end of the honing rotary motor 14 and the outside of the honing rotary spindle 92. The honing rotary motor 14 and the honing rotary spindle 92 are connected to each other through the pulley inside the top box 12. The honing rotating spindle 92 is connected to the top box 12 through a pulley, and the pulley is rotatably arranged in the top box 12. The top end of the honing rotating spindle 92 passes through the top box 12 and does not contact it.

A honing expansion motor 11 is also provided on the inner side of the honing power seat 10. When the honing reciprocating screw 131 rotates, since it is threadedly connected to the honing power seat 10, the honing power seat 10 will drive the honing tool 9 to move up and down in a straight line on the honing reciprocating screw 131 to realize the honing processing of the workpiece hole. The honing power seat 10 is rotatably connected to the honing rotating spindle 92, and the honing power seat 10 is slidably connected to the vertical guide rail 8. The purpose of the vertical guide rail 8 is to improve the stability of the honing power seat 10 when it moves up and down, and an accordion cover is also provided on the outside of the vertical guide rail 8 for protection.

[0045] like Figure 4 and 5 As shown, the upper surface of the honing equipment base 15 is located below the rough honing unit 2 and the fine honing unit 5, and a honing unit mounting seat 151 is provided. The structures of the fine honing Y-axis slide 16 and the rough honing Y-axis slide 20, as well as the structures of the fine honing X-axis slide 17 and the rough honing X-axis slide 21 are the same. The rough honing slide 6 includes the rough honing Y-axis slide 20 installed on the upper surface of the honing unit mounting seat 151 and located below the rough honing unit 2, and the rough honing X-axis slide 21 movably provided on the rough honing Y-axis slide 20. The fine honing slide 7 includes a rough honing Y-axis slide 20 installed on the upper surface of the honing unit mounting seat 151 and located below the fine honing unit 5. The fine honing Y-axis slide 16 and the fine honing X-axis slide 17 movably arranged on the fine honing Y-axis slide 16, the rough honing unit 2 and the fine honing unit 5 are respectively fixed on the honing unit mounting seat 151 by bolts, and the two are arranged side by side. During honing processing, the rough honing workpiece positioning mechanism 22 can use the rough honing Y-axis slide 20 for Y-axis movement, and then use the rough honing X-axis slide 21 for X-axis movement, which is used to adjust the lateral and longitudinal position adjustment of the rough honing workpiece positioning mechanism 22. The adjustment principle of the fine honing unit 5 is the same as that of the fine honing unit 5. The movement principle of the X-axis and Y-axis slides adopts the existing screw motion principle, which will not be described in detail here.

[0046] The upper end of the rough honing X-axis slide 21 is slidably connected to a rough honing slide 211, and a rough honing workpiece positioning mechanism 22 for rough honing of the workpiece is installed on the upper surface of the rough honing slide 211. A rough honing workpiece axial clamping mechanism 23 located directly above the rough honing workpiece positioning mechanism 22 is fixed in the rough honing chamber. The upper end of the fine honing X-axis slide 17 is slidably connected to a fine honing slide 171, and a fine honing workpiece positioning mechanism 18 for fine honing of the workpiece is installed on the upper surface of the fine honing slide 171. A fine honing workpiece axial clamping mechanism 19 located directly above the fine honing workpiece positioning mechanism 18 is fixed in the fine honing chamber. During processing, the rough honing X-axis slide 21 and the rough honing Y-axis slide 20 are used to move the positioned workpiece to the rough honing unit 2 according to the set coordinate system parameters. When moving to the specified position, the center of the honing tool 9 of the rough honing unit 2 coincides with the center of the rough honing workpiece positioning mechanism 22 on the vertical center line, and then the rough honing workpiece axial clamping mechanism 23 is pressed down on the workpiece, and the rough honing unit 2 is used to start rough honing of the workpiece hole. After the three holes of the cycloid wheel are rough honed in turn, according to the same principle, the workpiece is loaded onto the fine honing workpiece positioning mechanism 18, and then the fine honing operation is carried out.

[0047] like Figure 6 and 7As shown, the structural principles of the fine honing workpiece positioning mechanism 18 and the rough honing workpiece positioning mechanism 22 are the same. The fine honing workpiece positioning mechanism 18 is now described in detail. The fine honing workpiece positioning mechanism 18 includes a fixture base plate 31 installed on the upper surface of the fine honing slide 171. A pad 30 is also provided between the fine honing slide 171 and the fixture base plate 31. A positioning plate washer 32 is installed on the upper surface of the fixture base plate 31. A positioning plate 33 is fixed to the middle of the upper surface of the positioning plate washer 32. The upper surface of the positioning plate 33 is stacked with a cycloid wheel A27 and a cycloid wheel B29. The two sides of the clamp base 31 are correspondingly installed with a positioning cylinder 24, and the two sides of the clamp base 31 are symmetrically installed with a fixed seat 252 near the top of the positioning cylinder 24. A lever 25 is rotatably provided at the middle of one end of the fixed seat 252. The telescopic end of the positioning cylinder 24 is movably connected to the bottom end of the lever 25. The top end of the lever 25 is movably connected to the push rod 251. The upper end of the fixed seat 252 corresponds to The push rod 251 is provided with a stopper at one end, and one end of the push rod 251 slides through the stopper and is connected to the positioning block 28. The end of the push rod 251 adjacent to the positioning block 28 is sleeved with a return spring 26, and the middle part of the push rod 251 is provided with a retaining ring for blocking the return spring 26. When the operator places the cycloid wheel A27 and the cycloid wheel B29 on the positioning plate 33, the processing program is started, the positioning cylinder 24 automatically extends, pushing the bottom end of the lever 25 to tilt outward, and the top end of the lever 25 pushes the push rod 251 toward the cycloid wheel. The push rod 251 will push the positioning block 28 to move and position the cycloid wheel, and at the same time squeeze the return spring 26. It should be noted that the positioning block 28 has a tooth groove on the surface corresponding to the cycloid wheel, which is convenient for the positioning block 28 to position it, so that it can be better stuck on the surface of the cycloid wheel. After the cycloid wheel is positioned, the clamping cylinder 38 can be used to push the part baffle 34 to perform axial clamping on the workpiece, which is convenient for honing the workpiece hole.

[0048] like Figure 8As shown, the structural principles of the axial clamping mechanism 19 for the fine honing workpiece and the axial clamping mechanism 23 for the rough honing workpiece are the same. The axial clamping mechanism 19 for the fine honing workpiece is now described in detail. The axial clamping mechanism 19 for the fine honing workpiece includes a baffle connecting plate 35 installed in the fine honing chamber by bolts. The upper surface of one end of the baffle connecting plate 35 is connected to a cylinder mounting plate 37 through a side pad 36. Two clamping cylinders 38 are symmetrically installed on both sides of the upper end of the cylinder mounting plate 37. The telescopic ends of the two clamping cylinders 38 are commonly connected to a part baffle 34 located below the baffle connecting plate 35. Both sides of the cylinder mounting plate 37 are slidably connected to a There are two guide slides 40 in each group, and they are symmetrically distributed on both sides of the clamping cylinder 38. A guide sleeve 39 is provided at the bottom end of each guide slide 40 corresponding to the upper surface of the part baffle 34. The top end of the guide slide 40 is fixed to the cylinder mounting plate 37, and the bottom end of the guide slide 40 is slidably set in the guide sleeve 39. After the workpiece is positioned, the clamping cylinder 38 can be controlled to extend so that it pushes the part baffle 34 down to clamp the workpiece. In addition, during the pressing process, the cooperation of the guide slide 40 and the guide sleeve 39 can improve the stability of the part baffle 34 when pressed down.

[0049] A honing tool guide hole 41 for guiding the honing tool 9 is provided in the middle of the surface of the part baffle 34, the baffle connecting plate 35 and the cylinder mounting plate 37, and they are all located on the vertical center line. The purpose is to facilitate the positioning and pressing of the workpiece so that the honing tool 9 can pass through the honing tool guide hole 41 to hone the workpiece hole.

[0050] Working principle of the utility model: During rough honing, the cycloid wheel A27 and the cycloid wheel B29 are first stacked on the positioning plate 33 of the rough honing workpiece positioning mechanism 22. The operator starts the processing program, and the positioning cylinder 24 automatically extends, pushing the lever 25 to drive the push rod 251 toward the cycloid wheel. The push rod 251 then pushes the positioning block 28 to move and position the cycloid wheel.

[0051] After the cycloid wheel is positioned, the rough honing X-axis slide 21 and the rough honing Y-axis slide 20 automatically move the positioned workpiece to the bottom of the rough honing unit 2 according to the set coordinate system parameters. When it moves to the specified position, the pressing cylinder 38 on the rough honing workpiece axial pressing mechanism 23 automatically extends to push the part baffle 34 to perform axial pressing operation on the workpiece;

[0052] After the clamping is completed, the center of the honing tool 9 of the rough honing unit 2 coincides with the center of the rough honing workpiece positioning mechanism 22 on the vertical center line, and then the rough honing unit 2 is used to start the rough honing process on one of the workpiece holes on the cycloid wheel. After one of the workpiece holes is processed, the axial clamping mechanism 23 releases the workpiece, and the rough honing X-axis slide 21 and the rough honing Y-axis slide 20 move horizontally and vertically so that the other workpiece hole of the cycloid wheel is directly below the honing tool 9. The axial clamping mechanism 23 clamps the workpiece, and then the rough honing process is automatically performed. Based on this reasoning, continuous rough honing of multiple holes on the cycloid wheel can be achieved;

[0053] After the rough honing process is completed, the workpiece is loaded onto the fine honing workpiece positioning mechanism 18 according to the same steps and principles as above, and then the fine honing process is carried out. In this way, the honing process of multiple workpiece holes of two workpieces can be completed at one time, and the accuracy of the size and position of the workpiece holes can also be guaranteed during honing.
