Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, specifically to a hydraulic cylinder-based polishing processing equipment. Background Technology

[0002] Hydraulic cylinders are hydraulic actuators that convert hydraulic energy into mechanical energy, and are widely used in engineering machinery, metallurgical equipment, aerospace and other fields. The surface quality of the inner and outer walls of the hydraulic cylinder barrel directly affects the sealing performance, service life and operational stability of the hydraulic system. Therefore, polishing is a key process in the manufacturing of hydraulic cylinders.

[0003] Currently, most existing hydraulic cylinder polishing equipment achieves polishing by using a rolling mechanism to rub against the cylinder wall. For example, utility model patent CN211760269U discloses a polishing device for cylinder processing, utility model patent CN224347522U discloses a surface treatment device for hydraulic cylinder production, and invention patent application CN121223622A discloses a hydraulic cylinder grinding device with a protective structure. Most of these solutions are single-sided operation types, meaning that the same equipment can only polish the inner or outer wall of the cylinder. This single-sided operation mode results in the inner and outer walls of the hydraulic cylinder being polished separately, requiring secondary positioning, adjustment, and clamping, which prolongs the processing cycle of a single piece and makes the polishing operation inefficient. Summary of the Invention

[0037] A control panel 52 is provided on the side of the base 1. Each electrical device is powered by an external power supply. The entire device is controlled by the control panel 52. Since the control panel 52 is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0038] The lower grinding assembly includes a first horizontal shaft 9, multiple first grinding wheels 10, multiple first pads 11, and two first locking nuts 12. The multiple first grinding wheels 10 and multiple first pads 11 are all sleeved on the first horizontal shaft 9.

The two second horizontal shafts 13 are on the same horizontal axis, and their close ends are respectively provided with matching locking blocks and locking holes. The locking blocks have rectangular cross sections, and the locking holes are rectangular holes. The locking blocks are inserted into the locking holes to transmit torque.

[0040] The sliding assembly includes a slide 20 and two retaining sleeves 21. Two longitudinal rails 22 are fixedly mounted horizontally on the base 1. The two sides of the slide 20 are slidably fitted onto the two longitudinal rails 22 respectively. The two retaining sleeves 21 are fixedly mounted horizontally on the top of the two sides of the slide 20 respectively. The upper and lower semicircles of the retaining sleeves 21 are hinged by a pin, and the opposite side of the pin is fastened by a screw. The two ends of the first horizontal shaft 9 are rotatably fitted into the two retaining sleeves 21 respectively. A second motor 23 is fixedly mounted on one side of the slide 20. A third gear 24 is fixedly mounted on the top output end of the second motor 23. A fourth gear 25 is fixedly mounted on the end of the first horizontal shaft 9. The fourth gear 25 is meshed with the third gear 24. The two slides 20 are connected by a linkage assembly, which drives the two slides 20 to move synchronously in opposite directions.

[0041] The linkage assembly includes a third motor 26, a bracket 27, a screw 28, and two screw sleeves 29. The bracket 27 is vertically fixedly installed in the middle of the front side of the base 1, and the third motor 26 is horizontally fixedly installed in the middle of the rear side of the base 1. The screw 28 is horizontally and longitudinally arranged, with its front end rotatably sleeved in the bracket 27 and its rear end fixedly connected to the output shaft end of the third motor 26 through a coupling. The two screw sleeves 29 are respectively fixedly sleeved in the two slides 20, and both are threaded onto the screw 28.

[0042] The lifting assembly includes a frame 30, a slider 31, and a second telescopic cylinder 32. Guide rails 33 are horizontally fixedly installed on both ends of the base 1. The bottom end of the frame 30 is horizontally slidably embedded in the guide rails 33. The slider 31 is vertically slidably embedded in the frame 30. The outer end of the second horizontal shaft 13 is rotatably sleeved in the slider 31. The second telescopic cylinder 32 is vertically fixedly installed inside the frame 30, and its top output end is fixedly connected to the bottom end of the slider 31. A fourth motor 34 is fixedly installed on the upper side of one of the sliders 31. A fifth gear 35 is fixedly installed on the output shaft end of the fourth motor 34. A sixth gear 36 is fixedly installed on the outer end of the second horizontal shaft 13. The sixth gear 36 meshes with the fifth gear 35. A pushing assembly is provided on the upper side of the guide rail 33. The frame 30 moves back and forth on the guide rail 33 under the drive of the pushing assembly.

[0043] The pushing component includes a fifth motor 37, a seventh gear 38, and a rack 39. The rack 39 is horizontally fixedly embedded in the middle of the guide rail 33. The fifth motor 37 is fixedly installed on the outside of the upright 30. The seventh gear 38 is fixedly installed on the output shaft end of the fifth motor 37 and meshes with the rack 39. The fifth motor 37 drives the upright 30 to slide on the guide rail 33 through the meshing of the seventh gear 38 and the rack 39. After sliding to the preset position, the fifth motor 37 self-locks, thereby fixing the upright 30.

[0044] The limiting mechanism includes a horizontal rail 40 and two sets of clamping components. The horizontal rail 40 is horizontally arranged and its two ends are respectively fixedly installed on the middle of the upper side of the two longitudinal rails 22. The clamping components include a clamping bracket 41, a sliding sleeve 42, a first fastening bolt 43, a pressure roller 44, and a second fastening bolt 45. The clamping bracket 41 is vertically arranged and its bottom end is horizontally slidably sleeved on the horizontal rail 40. The sliding sleeve 42 is vertically slidably sleeved on the clamping bracket 41. The first fastening bolt 43 is threaded on the outer side of the bottom of the clamping bracket 41. The second fastening bolt 45 is threaded on the outer side of the sliding sleeve 42. The pressure roller 44 is vertically rotatably installed on the inner side of the clamping bracket 41.

[0045] When using this equipment to grind and polish hydraulic cylinders, initially, the two uprights 30 are at their outer ends, meaning the two second horizontal shafts 13 are separated, and the two first horizontal shafts 9 are close to each other. Driven by the third motor 26 and the screw 28, the two slides 20 move to the appropriate position, ensuring the two first horizontal shafts 9 are sufficient to support the hydraulic cylinder to be polished. The hydraulic cylinder is then horizontally placed between the two sets of first grinding wheels 10, with the first grinding wheels 10 on both sides contacting the outer wall of the hydraulic cylinder. Then, the two fifth motors 37 start, and through the meshing of the seventh gear 38 and rack 39, the uprights 30 move, thereby moving the second horizontal shafts 13 via the slider 31. Finally, the two second horizontal shafts 13 are connected by locking blocks and locking holes. Then, the two second telescopic cylinders 32 shorten, causing the second horizontal shafts 13 to move downwards, ultimately... Multiple second grinding wheels 14 contact the inner wall of the hydraulic cylinder, and then push the two clamps 41 so that the two pressure rollers 44 contact the two ends of the hydraulic cylinder respectively. The height of the pressure rollers 44 is adjusted by the sliding sleeve 42 and locked by the second fastening bolt 45. Then the first fastening bolt 43 is tightened to fix the clamps 41, thereby realizing the axial positioning of the two pressure rollers 44 on the hydraulic cylinder and completing the clamping operation on the bottom side of the hydraulic cylinder. After the bottom side clamping is completed, the two first telescopic cylinders 3 extend, driving the support frame 4 to move down, so that the middle part of the bottom side of the transmission belt 8 contacts the upper side of the hydraulic cylinder. The middle part of the bottom side of the transmission belt 8 bends and fits tightly against the upper part of the top of the hydraulic cylinder. During the gradual bending of the transmission belt 8, the upper pulley 5 is pulled down by the tension, thereby driving the two support blocks 6 to move down, stretching the two tension springs 7, thereby generating elastic force to tighten the transmission belt 8.

[0046] Once the lower clamping is complete and the rotary mechanism is tightly fitted to the top of the hydraulic cylinder, start the first motor 17, the second motor 23, and the fourth motor 34. The first motor 17, through the meshing of the first gear 18 and the second gear 19, drives the upper pulley 5 to rotate, thereby causing the transmission belt 8 to rotate under the support of the three pulleys 5. Under the action of friction, the hydraulic cylinder rotates. The second motor 23, through the meshing of the fourth gear 25 and the third gear 24, drives the first horizontal shaft 9 to rotate. The first horizontal shaft 9 drives multiple first grinding wheels 10 to rotate. The fourth motor 34, through the meshing of the fifth gear 35 and the sixth gear 36, drives the second horizontal shaft 13 to rotate. The second horizontal shaft 13 drives multiple second grinding wheels 14 to rotate.

[0047] The transmission belt 8 is in surface contact with the outer wall of the hydraulic cylinder, while the first grinding wheel 10 and the second grinding wheel 14 are in line contact with the wall of the hydraulic cylinder. The transmission belt 8 provides sufficient friction to make the hydraulic cylinder rotate in the driving direction of the transmission belt 8. The first grinding wheel 10 and the second grinding wheel 14 rotate in opposite directions at the position of contact with the hydraulic cylinder, thereby generating sliding friction between the first grinding wheel 10 and the second grinding wheel 14 and the hydraulic cylinder, thus achieving the function of grinding and polishing, and polishing the hydraulic cylinder.

[0048] With the cooperation of the rotary mechanism, two sets of upper grinding components and two sets of lower grinding components, the inner and outer walls of the hydraulic cylinder can be ground simultaneously in a single clamping operation without changing positions, saving time and improving processing efficiency.

[0049] The hydraulic cylinder is supported and clamped by two sets of upper and lower grinding components. With the assistance of two sets of clamping components, no additional clamping force is required, which effectively reduces the wear of the hydraulic cylinder and ensures the grinding quality.

[0050] After grinding and polishing are completed, the equipment stops operating. The first telescopic cylinder 3 shortens, driving the transmission belt 8 to move upward and disengage from the hydraulic cylinder. Then, the second telescopic cylinder 32 extends, causing the second grinding wheel 14 to disengage from the inner wall of the hydraulic cylinder. At the same time, the fifth motor 37 starts, causing the stand 30 to move outward, driving the second horizontal shaft 13 and the second grinding wheel 14 to disengage from the inside of the hydraulic cylinder. Then, the ground hydraulic cylinder is moved out between the two sets of first grinding wheels 10 to complete the unloading.

[0051] Depending on the size and specifications of the hydraulic cylinder to be ground, the effective distance and effective length between the upper and lower grinding components can be adjusted to perform grinding and polishing operations on hydraulic cylinders of different sizes and specifications.

[0052] During adjustment, the fastening screws on the two retaining sleeves 21 are unlocked, the upper side of the retaining sleeves 21 is flipped open, and the first horizontal shaft 9 is taken out. The first locking nuts 12 on both sides are unscrewed. Then, the number of first grinding wheels 10 is adapted according to the length of the hydraulic cylinder. The requirement is that the total length of the multiple first grinding wheels 10 is not less than the length of the hydraulic cylinder. The total length of the multiple first grinding wheels 10 located on the same first horizontal shaft 9 is adjusted by cooperating with the first pad 11. The adaptation method for the multiple second grinding wheels 14 on the second horizontal shaft 13 is to directly remove or install them from the inner end of the second horizontal shaft 13 away from the slider 31. After the two second horizontal shafts 13 are connected by the retaining blocks and retaining holes, the multiple second pads 15 on both sides are pushed closer to each other and tightened by the second locking nuts 16. The requirement is that the total length of the multiple second grinding wheels 14 is not less than the length of the hydraulic cylinder.

[0053] For adjusting the distance between the two sets of lower grinding components and the two sets of upper grinding components, the third motor 26 drives the screw 28 to rotate through the coupling. The screw 28 drives the two screw sleeves 29 to move the two slides 20 closer or further apart through the thread, thereby realizing the adjustment of the distance between the two sets of lower grinding components. The two second telescopic cylinders 32 extend or shorten synchronously, thereby realizing the adjustment of the distance between the two sets of upper grinding components and the lower grinding components.

[0054] Cleaning components are provided on the sides of both upper and lower grinding components. Each cleaning component includes a suction tube 46 and a brush plate 47. Connecting brackets 48 are fixedly installed at both ends of the suction tube 46. In the two bottom cleaning components, two connecting brackets 48 are fixedly connected to the inside of both sides of the slide 20. Both ends of the brush plate 47 are fixedly connected to the two connecting brackets 48. In the upper cleaning component, two connecting brackets 48 are fixedly connected to the inside of the two sliders 31. The two suction tubes on the bottom... Both the suction tube 46 and the brush plate 47 are integrated. The suction tube 46 and the brush plate 47 on the upper side are disconnected in the middle and connected by a slot. Both ends of the suction tube 46 are slidably fitted with a sleeve 49. The outer ends of the sleeves 49 are fixedly connected to the inner side of the connecting frame 48. A vacuuming device 50 is installed inside the base 1. The ends of the three suction tubes 46 are fixedly connected to the input end of the vacuuming device 50 through a hose 51. The sides of the three suction tubes 46 are provided with suction ports, which are long and narrow and communicate with the inside of the suction tubes 46.

[0055] The brush plate 47 slides into contact with the adjacent first grinding wheel 10 or second grinding wheel 14, thereby brushing off the metal shavings adhering to the first grinding wheel 10 or second grinding wheel 14 after it leaves the grinding area. The metal shavings fall near the suction port of the suction tube 46. Under the negative pressure suction of the dust collection device 50, the metal shavings generated during the grinding process are cleaned up in time. The first grinding wheel 10 and second grinding wheel 14 are cleaned up in time after leaving the grinding area, ensuring that the surface is clean and has sufficient friction when entering the grinding area, thereby further ensuring the grinding quality.

[0056] Based on the length of the hydraulic cylinder, the sleeves 49 on both sides of the suction pipe 46 can be pulled to completely block the suction ports on both sides, thereby ensuring that the effective adsorption area matches the length of the grinding area.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
