[0029] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] Please see Figures 1-12 This invention provides a technical solution: A mounting frame 1 includes a primary motor 2, a secondary motor 3, and a DC motor 4. The mounting frame 1 is cross-shaped. The outer wall of the top of the mounting frame 1 is fixedly connected to the outer wall of the bottom of the primary motor 2. One outer wall of the mounting frame 1 is fixedly connected to one outer wall of the secondary motor 3. A guide block 11 is fixedly connected to the middle of the interior of the mounting frame 1. A left-right moving mechanism is fixedly connected to the output end of the primary motor 2, and a right-down moving mechanism is fixedly connected to the output end of the secondary motor 3. The left-right moving mechanisms are used to drive the DC motor 4 to move left or right, facilitating the chamfering process of the compressor crankshaft. During the process, the generated tiny burrs or protrusions are polished to increase the burr removal effect. The left and right moving mechanism includes an arc ring 21. The output end of the first motor 2 passes through the inner wall of the top of the mounting frame 1 and is fixedly connected to the top of the arc ring 21. The arc ring 21 has a sliding groove 22 that connects the outer walls on both sides. The bottom of the arc ring 21 is rotatably connected to the lower part of the mounting frame 1. The middle position of the sliding groove 22 is hollow. The outer wall of the guide block 11 has grooves 112 in the horizontal and vertical directions. The outer wall of the guide block 11 has tracks 111 in the horizontal and vertical directions inside the grooves 112.

[0032] When the DC motor 4 drives the grinding blade to move left and right at an angle, it can effectively remove the tiny burrs or protrusions generated during the processing of the compressor crankshaft, thereby ensuring that the chamfer of the compressor crankshaft is ground evenly. This avoids the problem of unevenness or inconsistent roughness in the chamfer due to uneven grinding, and correspondingly increases the grinding effect on the compressor crankshaft, thus realizing the basic function of the grinding blade to smoothly grind the compressor crankshaft.

[0033] Example 2

[0034] Based on Embodiment 1, the up-and-down moving mechanism is used to drive the DC motor 4 to move up or down, which facilitates the change of radius according to the different curvatures of the compressor crankshaft, ensuring uniform grinding throughout the chamfer area and correspondingly increasing the uniformity of grinding. The up-and-down moving mechanism includes an arc ring 31. The output end of the second motor 3 passes through the interior of one side of the mounting frame 1 and is fixedly connected to the outer wall of one side of the arc ring 31. The outer wall of the other side of the arc ring 31 is rotatably connected to one side of the interior of the mounting frame 1. The middle position of the arc ring 31 is hollow, and a groove 32 is provided below the hollow part of the arc ring 31.

[0035] The vibrating housing 52 drives the mounting plate 41 to move up and down, and the movement of the mounting plate 41 causes the DC motor 4 to drive the grinding blade to move up and down. This allows for multi-directional adjustment of the grinding blade's angle, avoiding the grinding blade's inability to change angles by simply rotating. Consequently, the grinding blade becomes more adaptable to the different curvature radii of the compressor crankshaft, ensuring uniform grinding throughout the chamfered area. This facilitates targeted grinding of irregular surfaces, making them smoother and more rounded, and further achieving smooth grinding of the compressor crankshaft by the grinding blade.

[0036] Example 3

[0037] Based on Embodiment 2, a vibrating shell 52 is fixedly connected to one side of the connecting rod 62, and a mounting plate 41 is fixedly connected to one side of the vibrating shell 52. The outer wall of one side of the mounting plate 41 is fixedly connected to the outer wall of one side of the DC motor 4. A vertical rod is fixedly connected inside the vibrating shell 52, and a vibrating block 53 is slidably connected to the outer wall of the vertical rod. An L-shaped plate 5 is fixedly connected to the outer wall of one side of the vibrating shell 52, and a support rod 56 is fixedly connected to the outer wall of one side of the L-shaped plate 5. The outer wall of the support rod 56 is slidably connected to the outer wall of the slide groove 32. A vibrating motor 51 is fixedly connected to the inner wall of one side of the L-shaped plate 5. A gearless 55 is fixedly connected to the output end of the vibrating motor 51. A vibrating rod 54 is fixedly connected to the outer wall of the gearless 55 away from the axis. The outer wall of one side of the vibrating rod 54 is fixedly connected to the outer wall of one side of the vibrating block 53.

[0038] The slight vibration generated by the vibrating housing 52 can transmit the vibration force to the grinding blade on the DC motor 4 through the mounting plate 41, thereby causing the grinding blade to vibrate slightly. The slight vibration grinding can generate uniform pressure and grinding force on the surface of the compressor crankshaft, thereby achieving uniform treatment of the crankshaft surface. Furthermore, the slight vibration helps to eliminate friction and adhesion between the grinding blade and the compressor crankshaft, thereby improving cutting efficiency and chamfer smoothness.

[0039] Example 4

[0040] Based on Embodiment 2, a slider 6 is slidably connected inside the track 111, a limit block 61 is slidably connected inside the groove 112, a connecting rod 63 is fixedly connected to the middle of one side of the outer wall of the slider 6, the slider 6 is hollow inside, a limit rod 66 is movably inserted inside the slider 6, a return spring 69 is fixedly connected to the middle of the opposite side of the two limit rods 66, a handle 67 is fixedly connected to the outer wall of the top of the two limit rods 66, a connecting rod 62 is movably contacted to the outer wall of one side of the connecting rod 63, the outer walls of the connecting rod 62 and the connecting rod 63 are respectively threaded, the outer wall of the connecting rod 62 is threadedly connected to the limit block 61, and one side of the inner side of the limit block 61 is threadedly connected to one side of the outer wall of the connecting rod 63.

[0041] By moving the two handles 67 into the slider 6, the movement of the handles 67 can drive the two limit rods 66 to squeeze the return spring 69, thereby entering the interior of the slider 6. At this time, the width of the slider 6 is less than the width of the track 111, so the slider 6 can be taken out for maintenance or replacement, thus saving the replacement time of the slider 6.

[0042] Example 5

[0043] Based on Embodiment 2, a mounting rod 68 is fixedly connected to the middle position inside the slider 6, and a circular plate 65 is rotatably connected to the outer wall of one side of the mounting rod 68. The circular plate 65 has multiple square holes, and rollers 64 are rotatably connected inside the multiple holes.

[0044] When the slider 6 moves horizontally or vertically, the roller 64 drives the circular plate 65 to rotate on the mounting rod 68 according to the direction of the slider 6's movement. This makes the direction of the roller 64's movement consistent with the direction of the slider 6's movement, avoiding the roller 64's inability to move in only one direction. This increases the movement speed of the slider 6 and thus increases the flexibility of the roller 64.

[0045] In actual use, first, start the DC motor 4 on the mounting plate 41. Then, the movement of the DC motor 4 will drive the grinding blade to move. Then, the movement of the grinding blade will grind and chamfer the part of the compressor crankshaft that needs to be chamfered.

[0046] By starting the DC motor 4, the vibration motor 51 can be started to move. The movement of the vibration motor 51 will then cause the gearless 55 to drive the vibrating rod 54 to move. Since the vibrating rod 54 is installed on one side of the shaft of the gearless 55, when the gearless 55 moves, the vibrating rod 54 will drive the vibrating block 53 to move on the vertical rod inside the vibrating shell 52, thereby impacting the inside of the vibrating shell 52 and causing the vibrating shell 52 to vibrate slightly. This vibration force is then transmitted through the mounting plate 41 to the grinding blade on the DC motor 4, causing the grinding blade to vibrate slightly. This slight vibration grinding can generate uniform pressure and grinding force on the surface of the compressor crankshaft, thereby achieving uniform treatment of the crankshaft surface. Furthermore, the slight vibration helps to eliminate friction and adhesion between the grinding blade and the compressor crankshaft, thereby improving cutting efficiency and the smoothness of the chamfer.

[0047] It should be noted that the vertical rod is made of flexible material and can move with the vibration block 53.

[0048] When grinding the compressor crankshaft, to ensure the grinding blade can evenly grind the crankshaft, motor 2 is started. The movement of motor 2 causes the arc ring 21 to move, driving the vibrating housing 52. This movement of the vibrating housing 52 simultaneously causes the limiting block 61 and the slider 6 to move laterally within the groove 112 and track 111, respectively. The vibrating housing 52 then slides within the arc ring 31. This movement further causes the L-shaped plate 5 to slide, driving the support rod 56 within the sliding groove 32. The sliding groove 32 increases the support force on the vibrating housing 52, thereby enabling the mounting plate 41 to drive the DC... The grinding blade on motor 4 moves left and right at an angle to facilitate grinding the compressor crankshaft. The arc ring 31 allows the vibrating housing 52 to drive the DC motor 4, causing the DC motor 4 to move horizontally along the arc ring 31. This increases the stability of the DC motor 4 during left and right movements. The left and right angle movement of the grinding blade driven by the DC motor 4 effectively removes tiny burrs or protrusions generated during the machining process of the compressor crankshaft, ensuring uniform grinding of the crankshaft chamfer and avoiding unevenness or inconsistent roughness caused by uneven grinding. This, in turn, improves the grinding effect on the compressor crankshaft.

[0049] By stopping the movement of motor 2 and starting the movement of motor 3, the movement of motor 3 causes the slide 32 to drive the vibrating shell 52 to move up and down along the inside of the arc ring 21. At this time, the slider 6 and the limiting block 61 will move vertically inside the track 111 and the groove 112, thereby causing the vibrating shell 52 to drive the mounting plate 41 to move up and down. The movement of the mounting plate 41 then causes the DC motor 4 to drive the grinding blade to move up and down, which facilitates multi-directional adjustment of the grinding blade angle and avoids the grinding blade only rotating in one direction without being able to change the angle. Correspondingly, the grinding blade is more adaptable to the different curvature radii of the compressor crankshaft, thereby ensuring uniform grinding in the entire chamfer area. This facilitates targeted grinding of irregular surfaces, making them smoother and more rounded.

[0050] When the slider 6 moves inside the track 111, it drives the roller 64 on the circular plate 65 to rotate, thereby reducing the friction between the slider 6 and the track 111 and increasing the smoothness of the slider 6. Since the circular plate 65 and the mounting rod 68 are rotatably mounted, when the slider 6 moves horizontally or vertically, the roller 64 drives the circular plate 65 to rotate on the mounting rod 68 according to the direction of the slider 6's movement. This makes the direction of the roller 64's movement consistent with the direction of the slider 6's movement, avoiding the roller 64's inability to move in only one direction and thus increasing the flexibility of the roller 64.

[0051] The slider 6 is a crucial component that moves the vertical and horizontal mechanisms. During operation, the slider 6 experiences significant wear and tear. When replacement is needed, the limiting block 61 is rotated counterclockwise, causing it to move onto connecting rod 1 62. This separates connecting rod 1 62 from connecting rod 2 63. The operator then inserts their hand into the hollow of the slider 6, covering the handles 67 on both sides. Tightening the hand moves the handles 67 further into the slider 6. This movement of the handles 67 compresses the return spring 69, allowing it to enter the slider 6. Since the width of the slider 6 is now less than the width of the track 111, the slider 6 can be removed for maintenance or replacement, thus saving replacement time.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
