Description

Technical Field

[0001] The invention relates to the technical field of step pulley processing, in particular to a step pulley surface processing device. Background Art

[0002] The stepper is a mechanical transmission device, which is mainly used to adjust the speed of the equipment by changing the transmission ratio. Figure 8 As shown, the step pulley is composed of multiple wheels of different diameters fixed on the same shaft and arranged in a stepped manner.

[0003] During the production and processing of the step pulley, the step pulley needs to be surface treated, such as grinding, surface cleaning, etc. However, the following problems exist in the surface treatment of the step pulley: (1) Since the outer surface of the step shaft is conical and the diameter of each wheel disc is different, it is difficult for the existing grinding device to grind the outer wall of each wheel disc, and after grinding, the debris generated by grinding cannot be cleaned up immediately; (2) When grinding the outer wall, the inner wall cannot be polished at the same time, and the grinding efficiency is low; (3) When grinding the inner wall, if the diameter of the grinding block is large, it is difficult to insert it into the step pulley with a smaller inner diameter. If the diameter of the grinding block is small, after inserting it into the step pulley, the grinding block cannot contact the inner wall, resulting in the inability to grind, resulting in poor adaptability.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1

[0036] See also Figure 1-Figure 7 A step pulley surface treatment device includes a base 1, a processing table 2 is provided at the center of the base 1, and a rotating mechanism for driving the processing table to rotate is provided in the base. Specifically, the rotating mechanism includes a sixth motor 36 provided in the base, a transmission shaft connected to the sixth motor, a main gear 37 connected to the transmission shaft, a rotating column 38 connected to the bottom surface of the processing table, and a sub-gear 39 connected to the rotating column, wherein the main gear 37 and the sub-gear 39 are meshed. The sixth motor 36 is controlled to operate, and through the cooperation of the main gear 37 and the sub-gear 39, the rotating column 38 can be driven to rotate, thereby driving the processing table 2 to rotate.

[0037] The processing table 2 is provided with a plurality of grooves 3 with the center of the processing table as the center of the circle, and each groove 3 is provided with a positioning mechanism for fixing the step pulley at the center of the processing table. Specifically, the positioning mechanism includes a first cylinder 16 installed on the outer wall of the processing table 2 and corresponding to the groove, a clamping plate 17 connected to the telescopic end of the first cylinder, and a guide rail 18 provided in the groove. The clamping plate 17 is located in the groove 3 and is slidably connected to the guide rail 18. A V-shaped groove 19 is provided on the side of the clamping plate 17 facing the center of the processing table. When fixing the step pulley, the step pulley is placed on the processing table 2, and then all the first cylinders 16 are controlled to work at the same time, driving the clamping plate 17 to slide along the guide rail 18 in the groove 3, thereby clamping the lower part of the step pulley through the clamping plate 17. In addition, the telescopic strokes of all the first cylinders 16 are the same, and the first cylinders 16 work at the same time, so that after all the clamping plates 17 come into contact with the step pulley, the step pulley can be in the center position of the processing table 2.

[0038] The machine base 1 is connected to a frame 4 located on the periphery of the processing table. Both sides of the frame 4 are equipped with lifting mechanisms, and both lifting mechanisms are connected to a lifting seat 5 in a transmission manner. The lifting mechanisms can control the up and down movement of the lifting seat. Specifically, the lifting mechanism includes a vertical screw rod 20 that is rotatably connected to the frame, a first guide rod 21 that is connected to the frame and located on both sides of the screw rod, and a second motor 22 installed on the upper portion of the frame. The second motor 22 is in transmission connection with the screw rod 20, and the lifting seat 5 is threadedly connected to the screw rod 20. The lifting seat 5 is slidably connected to the first guide rod 21. Controlling the operation of the second motor 22 drives the screw rod 20 to rotate, which can drive the lifting seat 5 to rise and fall along the first guide rod 21.

[0039] One of the lifting seats 5 is equipped with an outer wall grinding mechanism. By controlling the lifting seat to descend one by one from top to bottom, each wheel of the step pulley can be ground by the outer wall grinding mechanism. The other lifting seat 5 is equipped with an outer wall cleaning mechanism. By controlling the lifting seat to descend one by one from top to bottom, each wheel of the step pulley can be cleaned by the outer wall cleaning mechanism. It should be noted that a touch screen display is also required on one side of the machine base for inputting set values so that the number of revolutions of the second motor each time can be set according to the width of the wheel, so that the lifting seat can descend the same distance each time, and after each descent, the outer wall grinding mechanism and the outer wall cleaning mechanism can be aligned with the corresponding wheel.

[0040] Specifically, the outer wall grinding mechanism includes a second cylinder 23 mounted on one of the lift bases 5, a third motor 24 connected to the telescopic end of the second cylinder, and a first transmission sleeve connected to the third motor via a coupling. The first transmission sleeve is splined with an outer grinding block 25. Once the outer wall grinding mechanism is aligned with the corresponding wheel disc, the second cylinder 23 is controlled to extend, driving the third motor 24 toward the processing table 2, bringing the outer grinding block 25 into contact with the sidewall of the wheel disc. The third motor 24 is then controlled to rotate, driving the outer grinding block 25. Simultaneously, the rotating mechanism drives the processing table to rotate, allowing the outer grinding block to grind the wheel disc.

[0041] The outer wall cleaning mechanism includes a third cylinder 26 mounted on another lifting seat 5, a fourth motor 27 connected to the telescopic end of the third cylinder, and a second transmission sleeve connected to the fourth motor through a coupling. The second transmission sleeve is splined with an outer cleaning brush 28. The third cylinder is controlled to work, which can drive the fourth motor to move toward the processing table so that the outer cleaning brush contacts the step pulley. When the outer wall cleaning mechanism is aligned with the corresponding wheel disc, the third cylinder 26 is controlled to extend, which can drive the fourth motor 27 to move toward the processing table 2 so that the outer cleaning brush 28 contacts the side wall of the wheel disc. Then, the fourth motor 27 is controlled to work, which drives the outer cleaning brush 28 to rotate. At the same time, the processing table 2 is driven to rotate by the rotating mechanism, so that the wheel disc can be cleaned by the outer cleaning brush 28.

[0042] A hydraulic cylinder 6 is fixed at the center of the upper part of the frame 4, and an inner wall grinding and cleaning integrated mechanism is installed at the telescopic end of the hydraulic cylinder 6; by controlling the extension of the hydraulic cylinder 6, the inner wall grinding and cleaning integrated mechanism can be driven to be inserted into the step pulley.

[0043] The inner wall grinding and cleaning integrated mechanism comprises a box body 7, a first motor 8 is installed in the box body 7, a transmission rod 9 is connected to the first motor 8 through a coupling, the lower end of the transmission rod 9 is connected to a first barrel 10, the outer wall of the first barrel 10 is connected to a plurality of inner brushes 11, the lower end of the first barrel 10 is connected to a second barrel 12, one side of the second barrel 12 is provided with an opening 13, a slide 14 is slidably connected in the opening 13, the outer side of the slide 14 is splined with an inner grinding block 15, the outer wall of the inner grinding block 15 is arc-shaped so that the inner grinding block can contact the inner wall of the step pulley, and in actual work, the corresponding inner grinding block 15 can be selected according to the model of the step pulley. A driving mechanism for driving the slide 14 to move in the second barrel is provided in the second barrel 12, and the inner grinding block 15 can be driven to make a linear motion in the opening by driving the slide 14. The driving mechanism includes a fifth motor 40 arranged in the second cylinder, a first rotating shaft 29 connected to the fifth motor through a coupling, and a first gear 30 connected to the first rotating shaft. The first rotating shaft 29 is rotatably connected to the second cylinder 12. The driving mechanism also includes a second rotating shaft 31 rotatably connected to the second cylinder, and a second gear 32 connected to the second rotating shaft. The first gear 30 is engaged with the second gear 32. Cams 33 are also connected to the first rotating shaft 29 and the second rotating shaft 31. The two cams 33 are controlled to rotate toward each other, which can push the slide 14 to move toward the outside of the second cylinder 12.

[0044] After the second cylinder 12 enters the step pulley 41, the fifth motor 40 is controlled to drive the first rotating shaft 29 and the second rotating shaft 31 to rotate toward each other through the cooperation of the first gear 30 and the second gear 32, thereby driving the two cams 33 to rotate toward each other, and the slide 14 is pushed by the cam 33 to make the slide 14 move toward the outside of the second cylinder 12, and the slide 14 drives the inner grinding block 15 to move outward until the inner grinding block 15 contacts the inner wall of the step pulley, and then the first motor 8 is controlled to work and drive the transmission rod 9 to rotate, which can drive the first cylinder 10 and the second cylinder 12 to rotate together, so that the inner wall of the step pulley is ground by the inner grinding block 15, and the inner wall of the step pulley is cleaned by the inner brush 11.

[0045] Example 2

[0046] Based on Example 1, second guide rods 34 are connected to the upper and lower ends of the second cylinder 12. Springs 35 are sleeved around the outer periphery of the second guide rods 34. The upper and lower sides of the slide 14 are slidably connected to the two second guide rods 34, respectively. One end of the spring 35 abuts against the inner wall of the second cylinder 12 on the side away from the opening, and the other end of the spring 35 is connected to the slide 14. The provision of the second guide rods 34 improves the stability of the slide 14 during movement. The first rotating shaft 29 and the second rotating shaft 31 rotate in opposite directions, causing the two cams 33 to rotate in opposite directions. Under the restoring force of the springs 35, the two slides 14 move into the second cylinder 12 until they abut against the cams 33, thereby causing the inner grinding block 15 to move into the second cylinder 12, thereby adjusting the outer length of the inner grinding block 15 to accommodate the step pulley with a smaller inner diameter.
