Description

Technical Field

[0001] This utility model relates to the field of machining polishing and grinding technology, specifically to a fine polishing and grinding equipment for machining. Background Technology

[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical actions to reduce the surface roughness of a workpiece in order to obtain a bright and smooth surface. It involves using polishing tools and abrasive particles or other polishing media to modify the surface of a workpiece.

[0003] For example, a fine polishing and grinding equipment for machining, with announcement number "CN221871342U", places the metal pipe to be polished on an auxiliary support plate. The extension end of the cylinder is controlled to expand and move downward in the vertical direction. The upper pressure plate, in conjunction with the auxiliary support plate, clamps and fixes the pipe. After clamping, the grinding head is inserted into the pipe, thereby realizing automated grinding of the inner diameter of the pipe. It has a simple structure, high reliability, effectively reduces labor intensity, and can fully ensure the uniformity of grinding of the inner wall of the pipe, thus improving product quality. However, this precision polishing and grinding equipment for machining cannot adjust the grinding head according to the diameter of the metal tube, thus it can only process metal tubes of a fixed diameter. To process metal tubes of different diameters, the corresponding grinding head needs to be changed, and there is no guarantee that the corresponding grinding head will always be available, which has strong limitations. At the same time, this precision polishing and grinding equipment can only polish the inner wall of the metal tube. If the outer wall of the metal tube needs to be polished, it needs to be polished separately, which requires the operator to reposition and clamp it, which consumes the operator's time and reduces work efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing fine polishing and grinding equipment for machining, which cannot adjust the grinding head according to the diameter of the metal tube, thus limiting its processing to metal tubes of a fixed diameter. Processing metal tubes of different diameters requires changing the corresponding grinding head, and the availability of a suitable grinding head cannot be guaranteed, resulting in significant limitations. Furthermore, this equipment can only polish the inner wall of the metal tube; polishing the outer wall requires separate grinding, necessitating repositioning and clamping by the operator, consuming time and reducing work efficiency. Therefore, this invention proposes a fine polishing and grinding equipment for machining.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a fine polishing and grinding equipment for machining, including a base plate, a first outer shell fixedly connected to the upper left part of the base plate, an adjustment mechanism provided inside the first outer shell, two first cylinders fixedly connected to the middle part of the base plate, a lifting plate fixedly connected to the output end of each first cylinder, the inner wall of the lifting plate slidably connected to a sliding plate, a first motor fixedly connected to the upper end of the sliding plate, a second outer shell fixedly connected to the output shaft of the first motor, and a grinding mechanism provided inside the second outer shell.

[0007] Preferably, a multi-stage cylinder is fixedly connected to the protrusion on the right end of the lifting plate, and a sliding plate is fixedly connected to the output end of the multi-stage cylinder. A second cylinder is fixedly connected to the lower end of the left side support plate of the base plate, and an upper curved plate is fixedly connected to the output end of the second cylinder.

[0008] Preferably, the adjusting mechanism includes a third cylinder, the output end of which is fixedly connected to a rack, the outer wall of one rack meshes with a gear, the outer wall of the other end of the gear meshes with another rack, the protruding inner wall of the lower end of the rack is slidably connected to a first slide rod, both ends of the two first slide rods are fixedly connected to a first outer shell, and the upper outer ends of the two racks are fixedly connected to a slider.

[0009] Preferably, the upper ends of the two sliders are respectively fixedly connected to the lower curved plates, and the outer wall of the second cylinder is fixedly connected to the first outer shell.

[0010] Preferably, the inner walls of the bending plates are rotatably connected to rubber rollers via bearings, a fourth cylinder is fixedly connected to the middle of the base plate, a vertical block is fixedly connected to the output end of the fourth cylinder, a second motor is fixedly connected to the outer wall of the vertical block, a polishing roller is fixedly connected to the output shaft of the second motor, the right end of the polishing roller is rotatably connected to a sliding plate via a bearing, and the outer wall of the sliding plate is slidably connected to the base plate.

[0011] Preferably, the polishing mechanism includes a handle, a worm gear is fixedly connected to the rotating shaft of the handle, the worm gear meshes with a worm wheel, a turntable is fixedly connected to the rotating shaft of the worm wheel, a plurality of sliding grooves are machined on the inner wall of the turntable, the inner walls of the plurality of sliding grooves are slidably connected to a second sliding rod, and the outer walls of the second sliding rod are slidably connected to a limiting block.

[0012] Preferably, the outer walls of the limiting blocks are fixedly connected to the inner walls of the second housing, and the end of the worm gear is rotatably connected to the second housing via a bearing.

[0013] Preferably, a support plate is fixedly connected to the left side of the skateboard, and the inner wall of the support plate is rotatably connected to the first motor through a bearing.

[0014] This utility model proposes a fine polishing and grinding equipment for machining, which has the following advantages: Through the cooperation of the grinding mechanism and the first motor, the handle rotation drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel rotation drives the turntable to rotate, which in turn drives multiple sliding grooves to rotate. The sliding grooves drive multiple sliding rods to move outward. The sliding rods move linearly due to the limiting block, and thus move outward continuously as the turntable rotates. When the sliding rods move outward to the same diameter as the inner wall of the steel pipe, the handle rotation stops. The worm gear has a self-locking function, which keeps the position of the sliding rods unchanged. The ends of the sliding rods are all equipped with arc-shaped grinding strips that can cooperate with the inside of the steel pipe to achieve the purpose of grinding. This realizes a grinding mechanism that can be adjusted according to the diameter of the steel pipe, eliminating the need for operators to change different grinding heads each time. It can be adjusted according to the diameter of the steel pipe, thus reducing limitations.

[0015] Through the coordination of the adjustment mechanism and the polishing roller, the output end of the third cylinder extends, driving the upper rack to move to the left, which in turn drives the gear to rotate. The gear rotation drives the lower rack to move to the right. The two racks move at the same speed and distance. The rack movement is limited by the first sliding rod to move horizontally. The rack movement drives the slider to move inward. The movement of the two sliders drives the lower curved plate to move inward, which in turn drives the rubber roller to move inward. The distance between the two rubber rollers is adjusted according to the size of the steel pipe. The two rubber rollers serve to support the steel pipe. When the outer wall of the polishing roller is pressed against the outer wall of the steel pipe, the second motor is started. The output shaft of the second motor rotates, driving the polishing roller to rotate at high speed. The rotation of the polishing roller polishes the outer wall of the steel pipe, realizing the polishing of the outer wall of the steel pipe. This eliminates the need for workers to polish the outer wall of the steel pipe separately, saving time for re-clamping and fixing the steel pipe, thereby improving work efficiency.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] See attached document Figure 1-8 :

[0027] In this embodiment, a fine polishing and grinding equipment for machining is used to polish steel pipes. It includes a base plate 1, a first outer shell 3 fixedly connected to the upper left part of the base plate 1, an adjustment mechanism 4 inside the first outer shell 3, two first cylinders 2 fixedly connected to the middle part of the base plate 1, and lifting plates 15 fixedly connected to the output ends of the first cylinders 2. The inner wall of the lifting plate 15 is slidably connected to the slide plate 5. A first motor 6 is fixedly connected to the upper end of the slide plate 5, and a second outer shell 7 is fixedly connected to the output shaft of the first motor 6. A grinding mechanism 8 is provided inside the second outer shell 7. The extension and retraction of the output ends of the first cylinders 2 drives the lifting plate 15 to move. The movement of the lifting plate 15 drives the slide plate 5, the first motor 6, and the multi-stage cylinder 13 to move, thereby driving the second outer shell 7 and the grinding mechanism 8 to move up and down. A multi-stage cylinder 13 is fixedly connected to the protrusion on the right end of the lifting plate 15, and the slide plate 5 is fixedly connected to the output end of the multi-stage cylinder 13.

[0028] The output end of the multi-stage cylinder 13 extends and retracts, causing the slide plate 5 to slide within the lifting plate 15. Limited by the lifting plate 15, the slide plate 5 moves horizontally, driving the first motor 6 to move, which in turn drives the grinding mechanism 8. A second cylinder 9 is fixedly connected to the lower end of the left side support plate of the base plate 1. The output end of the second cylinder 9 is fixedly connected to the upper curved plate 12. The inner walls of the curved plate 12 are rotatably connected to the rubber roller 11 via bearings. A fourth cylinder 17 is fixedly connected to the middle of the base plate 1. A vertical block 19 is fixedly connected to the output end of the fourth cylinder 17. A second motor 10 is fixedly connected to the outer wall of the vertical block 19. The output shaft of the second motor 10 is fixedly connected to a polishing roller 14. The right end of the polishing roller 14 is connected to the slide plate 15 via a bearing. The movable plate 18 is rotatably connected, and the outer wall of the sliding plate 18 is slidably connected to the base plate 1. The output end of the fourth cylinder 17 extends and retracts, causing the vertical block 19 to move, which in turn drives the second motor 10 to move. The movement of the second motor 10 drives the polishing roller 14 to move, which in turn drives the sliding plate 18 to move. The sliding plate 18 is vertically moved by the limit of the base plate 1. The output shaft of the second motor 10 rotates, causing the polishing roller 10 to rotate. A support plate 16 is fixedly connected to the left side of the slide plate 5. The inner wall of the support plate 16 is rotatably connected to the first motor 6 through a bearing. The support plate 16 ensures the stability of the first motor 6 when it rotates, thereby reducing the vibration caused by the excessive length of the output shaft of the first motor 6 during rotation, thus improving the polishing accuracy and achieving fine processing.

[0029] See attached document Figure 1-2 6 and 8:

[0030] The adjusting mechanism 4 includes a third cylinder 401. A rack 402 is fixedly connected to the output end of the third cylinder 401. The extension and retraction of the output end of the third cylinder 401 drives the rack 402 to move. The outer wall of one rack 402 meshes with a gear 403. The outer wall of the other end of the gear 403 meshes with another rack 402. The movement of one rack 402 causes the gear 403 to rotate, thereby driving the other rack 402 to move in the opposite direction. The protruding inner wall of the lower end of each rack 402 is slidably connected to the first slide rod 405. The movement of rack 402 is limited by the horizontal movement of the first slide rod 405. Both ends of the two first slide rods 405 are fixedly connected to the first outer shell 3. The upper outer sides of the two racks 402 are fixedly connected to sliders 404. The two racks 402 move in opposite directions synchronously, driving the two sliders 404 to move in opposite directions synchronously. The upper ends of the two sliders 404 are respectively fixedly connected to the lower side bending plate 12. The two sliders 404 move in opposite directions synchronously, driving the lower side bending plate 12 to move in opposite directions synchronously. The outer wall of the second cylinder 9 is fixedly connected to the first outer shell 3.

[0031] See attached document Figure 1-5 And 7:

[0032] The grinding mechanism 8 includes a handle 801, with a worm gear 802 fixedly connected to the rotating shaft of the handle 801. The worm gear 802 meshes with a worm wheel 803. Rotation of the handle 801 drives the worm gear 802 to rotate, which in turn drives the worm wheel 803 to rotate. A turntable 804 is fixedly connected to the rotating shaft of the worm wheel 803. Multiple sliding grooves 805 are machined on the inner wall of the turntable 804. Rotation of the worm wheel 803 drives the turntable 804 to rotate, which in turn drives the multiple sliding grooves 805 to rotate. The inner walls of the multiple sliding grooves 805 are all slidably connected to the second sliding rods 806. Rotation of the multiple sliding grooves 805 drives the multiple second sliding rods 806 to move. The outer walls of the second sliding rods 806 are all slidably connected to the limiting blocks 807. The movement of the second sliding rods 806 is limited by the limiting blocks 807 to make them move linearly. The outer walls of the limiting blocks 807 are all fixedly connected to the inner wall of the second outer shell 7. The end of the worm gear 802 is rotatably connected to the second outer shell 7 through a bearing.

[0033] Working principle:

[0034] When fine polishing and grinding of steel pipes is required:

[0035] Preparation:

[0036] The staff started the third cylinder 401 (e.g.) Figure 6 The output end of the third cylinder 401 extends and drives the upper rack 401 to move to the left, thereby driving the gear 403 to rotate. The rotation of the gear 403 drives the lower rack 402 to move to the right. The two racks 402 move at the same speed and distance. The movement of the rack 402 is limited by the first slide rod 405 to move horizontally. The movement of the rack 402 drives the slider 404 to move inward. The movement of the two sliders 404 drives the lower bending plate 12 to move inward, thereby driving the rubber roller 11 to move inward. The distance between the two rubber rollers 11 below is adjusted according to the size of the steel pipe. After reaching the appropriate position, the third cylinder 401 stops so that the two rubber rollers 11 stop at that position.

[0037] Then start the second cylinder 9 (e.g.) Figure 2 The output end of the second cylinder 9 extends and drives the upper curved plate 12 to move the rubber roller 11 downward. The second cylinder 9 stops when the lower end of the rubber roller 11 is pressed against the steel pipe. The steel pipe is fixed by three rubber rollers 11, with their centers aligned with the center of the grinding mechanism 8. Then, the forward rotation handle 801 (as shown)... Figure 7 The handle 801 rotates, causing the worm gear 802 to rotate, which in turn drives the worm wheel 803 to rotate (e.g., Figure 5 The worm gear 803 rotates, driving the turntable 804 to rotate (e.g., Figure 3The rotation of turntable 804 drives multiple sliding grooves 805 to rotate, and the rotation of sliding grooves 805 drives multiple second sliding rods 806 to move outward. The second sliding rods 806 move linearly due to the limiting block 807, and thus move outward continuously as turntable 804 rotates. When the second sliding rods 806 move outward to the same diameter as the inner wall of the steel pipe, the rotation of handle 801 can be stopped. The worm gear 803 and worm 802 have self-locking properties, so that the position of the second sliding rods 806 remains unchanged. The ends of the second sliding rods 806 are all equipped with arc-shaped grinding strips, which can cooperate with the inside of the steel pipe to achieve the purpose of grinding. Reversing the handle 801 can drive the second sliding rods 806 to move inward. The working method is the opposite of the above, and it can be adjusted according to the diameter of the steel pipe.

[0038] Grinding and polishing process of the inner wall of steel pipe:

[0039] Start the first cylinder 2 (e.g.) Figure 2 The output end of the first cylinder 2 extends, driving the lifting plate 15 to move upward, which in turn drives the multi-stage cylinder 13 and the first motor 6 to move upward. The upward movement of the first motor 6 drives the grinding mechanism 8 to move upward. When the center height of the grinding mechanism 8 is the same as the center of the steel pipe, the first cylinder 2 stops, and then the output shaft of the first motor 6 is started. The rotation of the output shaft of the first motor 6 drives the second outer shell 7 to rotate, which in turn drives the grinding mechanism 8 to rotate. The multi-stage cylinder 13 is started, and the output end of the multi-stage cylinder 13 extends, driving the sliding plate 5 to move to the left, which in turn drives the grinding mechanism 8 to move to the left. The grinding mechanism 8 enters the inside of the steel pipe for grinding. When the grinding mechanism 8 extends from the other end of the steel pipe, the output end of the multi-stage cylinder 13 is controlled to retract back to its original position, driving the grinding mechanism 8 to move to the right and simultaneously grinding the inner wall of the steel pipe a second time, making the grinding more thorough and realizing the grinding of the inner wall of the steel pipe.

[0040] Grinding process of steel pipe outer wall:

[0041] When grinding the outer wall of the steel pipe, the fourth cylinder 17 is activated. The output end of the fourth cylinder 17 extends, causing the vertical block 19 to move upward, which in turn drives the second motor 10. The movement of the second motor 10 drives the polishing roller 14, which in turn drives the sliding plate 18. The sliding plate 18 is limited by the base plate 1 and moves vertically upward. When the outer wall of the polishing roller 14 is pressed against the outer wall of the steel pipe, the fourth cylinder 17 is stopped. The polishing roller 14 is directly below the steel pipe. Then the second motor 10 is activated (e.g., ...). Figure 1The output shaft of the second motor 10 rotates, driving the polishing roller 14 to rotate at high speed. The polishing roller 14 rotates to polish the outer wall of the steel pipe. During polishing, the steel pipe will rotate, so the entire outer wall of the steel pipe can be polished, thus realizing the polishing of the outer wall of the steel pipe. After polishing is completed, the power of the second motor 10 is turned off, and the output end of the second cylinder 9 is controlled to retract. The retraction of the output end of the second cylinder 9 drives the rubber roller 11 to move upward, thereby separating it from the steel pipe. The worker can then remove the steel pipe. After all is completed, all power is turned off. The polishing mechanism 8 can adjust its size according to the inner diameter of the steel pipe to match the inner wall of the steel pipe, making the processing of the steel pipe more precise.
