Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Example

[0069] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 9 and Figure 10 As shown, this embodiment provides a polishing machine, including a base frame 10, a clamping mechanism 20, a processing mechanism 30, and a wax supply mechanism 40. The top surface of the base frame 10 is provided with a cross guide unit 11 and a vertical frame 12. The vertical frame 12 is provided with vertical guide units 13 arranged towards or away from the cross guide unit 11. The clamping mechanism 20 is provided on the cross guide unit 11 and is used to clamp the workpiece. The processing mechanism 30 includes a polishing unit 31 provided on the vertical guide unit 13 and a power unit 32 that drives the polishing unit 31 to slide vertically. The wax supply mechanism 40 is provided on the frame 311 of the polishing unit 31 and is used to polish the polishing unit 31 with wax. The cross guide unit 11 can be a cross slide rail, and the vertical guide unit can be a slide rail.

[0070] Specifically, the power unit 32 can be a servo motor to drive the screw to rotate, while the frame 311 of the grinding unit 31, which is slidably mounted on the vertical guide unit 13, is threadedly engaged with the screw (that is, a protrusion can be designed on the grinding unit 31 to engage with the screw to drive it to move up and down), thus achieving the purpose of driving the grinding unit 31 to move up and down.

[0071] In use, the workpiece is mounted on the clamping mechanism 20, and the initial position between the grinding unit 31 and the workpiece is adjusted by the cross guide unit 11 and the vertical guide unit 13. Then, during grinding, the grinding unit 31 is ground according to its designed travel trajectory. During grinding, the wax supply mechanism 40 supplies wax to the grinding unit 31 to achieve the purpose of grinding and waxing the workpiece, thus achieving different grinding objectives.

[0072] Specifically, in this embodiment, the polishing unit 31 can be a multi-unit structure, matched with the same number of clamping mechanisms 20 and wax supply mechanisms 40, thus forming multiple polishing units side by side, improving the polishing effect of the cleaning machine. To facilitate understanding of the solution, the specific structure of a set of polishing units 31, clamping mechanisms 20, and wax supply mechanisms 40 will be described.

[0073] like Figure 6 , Figure 11 and Figure 12 As shown, in this embodiment, the wax supply mechanism 40 includes a fixed cylinder 41 with both ends open, a wax supply unit 42 disposed in the fixed cylinder 41, and a displacement unit 43 that drives the wax supply unit 42 to move toward or away from the polishing unit 31. The displacement unit 43 includes a slide 431 disposed in the fixed cylinder 41 and a displacement motor 432 disposed on the slide 431. The wax supply unit 42 is provided with a first protrusion 421 that moves back and forth on the output shaft of the displacement motor 432.

[0074] Specifically, the displacement motor 432 can be a servo motor, fixed inside the fixed cylinder 41. It can drive the first protrusion 421 to move axially along the fixed cylinder 41 through the structure of the threaded rod (the specific implementation method is explained in detail below). The wax supply unit 42 is fixedly installed with the first protrusion 421, so the wax supply unit 42 is driven to move synchronously to achieve the purpose of waxing the polishing wheel 3134 of the polishing unit 31.

[0075] like Figure 6 , Figure 11 and Figure 12As shown, in this embodiment, the wax supply unit 42 includes a conveying channel 422, a wax supply power unit 423 disposed at one end of the conveying channel 422, a limiting block 424 disposed at the other end of the conveying channel 422, a blocking power unit 425 that drives the limiting block 424 to be located at or away from the port of the conveying channel 422, and a pushing power unit 426 that pushes, clamps or separates the wax block in the conveying channel 422; the fixing frame of the blocking power unit 425 is disposed on the fixing cylinder 41, and the pushing power unit 426 is disposed at the other end of the conveying channel 422. The blocking power unit 425 can be a cylinder.

[0076] Specifically, the wax block in the wax supply unit 42 can be a long strip and placed in the conveyor channel 422. The wax supply power unit 423 pushes the wax block within the conveyor channel 422, thus moving the wax block to supply wax. Therefore, the wax supply power unit 423 can be a pneumatic cylinder or a hydraulic cylinder. This creates a linear movement of the wax block, which extends out from the other end of the conveyor channel 422 to achieve the wax supply effect.

[0077] Furthermore, to precisely control the length of the wax block extending from the conveyor channel 422, a limiting block 424 is installed at the other end of the conveyor channel 422. The limiting block 424 is driven by the blocking power unit 425 and is spaced apart from the outlet of the conveyor channel 422. The distance of the interval is manually designed, which is the set distance for each wax block push. This achieves limiting, blocking, and separation by driving the blocking block with the blocking power unit 425, so that when pushing wax, it is blocked to determine the extension distance, and the wax block is clamped and fixed by the blocking power unit 426. After separation, the conveyor channel 422 can be driven by the displacement motor 432 to move axially along the fixed cylinder 41 for waxing. The motor is driven by a threaded conveyor, which can provide precise wax supply, thus achieving the purpose of precise wax supply.

[0078] Specifically, a protrusion can be designed on the outside of the fixed cylinder 41. The central shaft of the limiting block 424 is hinged to the protrusion, and the blocking power unit 425 is set on the top surface of the protrusion. The driving end of the limiting block 424 is provided with an elongated hole, the length of which can be set according to the arc of the swing of the limiting block 424. The blocking end of the limiting block 424 is provided with an elbow structure, and the output shaft of the blocking power unit 425 is provided with a sliding shaft that is inserted into and slides through the elongated hole. The elbow structure design allows the abutting surface of the limiting block 424 to be parallel to the outlet of the conveyor 422, while reducing the length between the hinge shaft and the blocking end, facilitating avoidance by tilting the blocking end. The elongated hole is designed to accommodate the stroke of the output shaft of the blocking power unit 425 during linear movement, so as to achieve the purpose of being driven by a cylinder. The blocking power unit 425 can be a cylinder.

[0079] like Figure 6 , Figure 11 and Figure 12 As shown, in this embodiment, the slide 431 includes a first end plate 4311 and a second end plate 4312 slidably sleeved inside the fixed cylinder 41, and a connecting plate 4313 connected between the first end plate 4311 and the second end plate 4312; the side of the conveying channel 422 is provided with at least one plane, the displacement motor 432 is disposed on the first end plate 4311, and a first bearing is disposed between the output shaft of the displacement motor 432 and the first end plate 4311, a second bearing is disposed between the output shaft of the displacement motor 432 and the second end plate 4312, and a threaded structure is disposed between the output shaft of the displacement motor 432 and the first protrusion 421; a guide rod 4314 is also disposed between the first end plate 4311 and the second end plate 4312, the guide rod 4314 and the output shaft of the displacement motor 432 are symmetrically arranged with respect to the conveying channel 422, and a second protrusion 427 is disposed on the conveying channel 422 and slides and limits the guide rod 4314.

[0080] Specifically, taking a rectangular slide 431 as an example, when the connecting plates 4313 are two symmetrically arranged pieces, both sides of the slide 431 are open. Therefore, the conveyor channel 422 installed inside the slide 431 has at least two outer sides that communicate with the outside, that is, the open part is the position where the first protrusion 421 moves back and forth. The first protrusion 421 is fixed on the conveyor channel 422 or integrally formed; similarly, the second protrusion 427 is fixed on the conveyor channel 422 or integrally formed.

[0081] In use, the displacement motor 432 is turned on to drive the output shaft to rotate. Through the threaded structure, the first protrusion 421 moves back and forth linearly along the output shaft, simultaneously causing the conveyor 422 to move back and forth linearly. Because the conveyor 422, the first end plate 4311, and the second end plate 4312 can be designed with a non-circular contour (i.e., a planar design), the conveyor 422 and the first protrusion 421 will not rotate with the threaded structure, thus achieving the purpose of linear movement.

[0082] Furthermore, the guide rod 4314 provides a sliding support point, making the conveyor 422 move more smoothly along the slide 431. The increased structural stability helps improve the accuracy of wax block supply.

[0083] like Figure 5 , Figure 6 and Figure 8 As shown, in this embodiment, the grinding unit 31 includes a frame 311, a transmission gear 312, a power frame 313, and a swing guide unit 314. The frame 311 is mounted on the vertical guide unit 13. The transmission gear 312 includes an outer ring portion 3121, an inner ring portion 3122, and a bearing portion 3123 (e.g., ...) sleeved between the outer ring portion 3121 and the inner ring portion 3122. Figure 7As shown, the inner ring 3122 is disposed on the frame 311, and the inner ring 3122 is fitted onto the fixed cylinder 41 with a gap; the power frame 313 is disposed on the outer ring 3121, and the fixed cylinder 41 is provided with a protruding ring 411 mounted on the power frame 313 or the outer ring 3121; the swing guide unit 314 is disposed on the frame 311, and the swing guide unit 314 is disposed parallel to one of the guide units in the cross guide unit 11; the frame 311 is provided with a rack structure 3111 that meshes with the transmission gear 312, and a drive unit 3112 that drives the rack structure 3111 to move back and forth on the swing guide unit 314.

[0084] For example, a four-unit grinding unit 31 can be designed, in which the drive unit 3112 can be a servo motor or a servo motor, which can drive the rack structure 3111 to move back and forth (the drive unit 3112 can also be a cylinder or a hydraulic cylinder, which directly drives the rack structure 3111 to move along the swing guide unit 314), thereby causing the outer ring 3121 of the transmission gear 312 to rotate, so that the power frame 313 and the fixed cylinder 41 mounted on the outer ring 3121 rotate synchronously. In this way, the fixed cylinder 41 and the power frame 313 can be linked to achieve the effect of grinding the workpiece efficiently and with high quality.

[0085] Specifically, the transmission gear 312 is a gear with a bearing in the middle. Thus, the transmission gear 312 consists of an inner ring 3122 (annular structure) and an outer ring 3121 (annular structure with outer ring teeth), connected in the middle by a bearing. Therefore, the power frame 313 can be bolted to the outer ring 3121, and the convex ring 411 on the fixed cylinder 41 can be bolted to the power frame 313, achieving synchronous rotation with the outer ring 3121. Then, the inner ring 3122 is fixed to the frame 311 for installation. Next, the drive unit 3112 drives the rack to move, driving the outer ring 3121 to rotate. The rack structure 3111 can synchronously drive the four sets of transmission gears 312 to rotate, achieving linkage and ensuring that the four sets of transmission gears 312 perform the same actions, guaranteeing the quality of workpiece processing.

[0086] Furthermore, to facilitate the installation of the inner ring 3122, a bushing can be locked between the frame 311 and the inner ring 3122 to achieve connection. The bushing allows for flexible design of the spacing between the frame 311 and the inner ring 3122, improving design flexibility and practicality.

[0087] like Figure 9 and Figure 10As shown, in this embodiment, the rack structure 3111 includes a fixed plate 3113 and a rack plate 3114 disposed on one surface of the fixed plate 3113, and the rack plate 3114 is meshed with the transmission gear 312; the other surface of the fixed plate 3113 is disposed on the slider of the swing guide unit 314, and a drive rack 3115 parallel to the rack plate 3114 is disposed on the other surface of the fixed plate 3113; a drive gear 3116 meshing with the drive rack 3115 is disposed on the output shaft of the drive unit 3112; the drive unit 3112 can be a servo motor or a servo motor.

[0088] Specifically, the drive gear 3116 on the drive unit 3112 drives the drive rack 3115 to move back and forth, which in turn causes the fixed plate 3113 to move back and forth synchronously along the swing guide unit 314. Simultaneously, multiple rack plates 3114 on the fixed plate 3113 mesh with their corresponding transmission gears 312, that is, the rack plates 3114 drive the meshing transmission gears 312 to rotate, achieving the purpose of synchronously driving multiple transmission gears 312 to rotate, which in turn drives the motor frame to perform corresponding swinging movements. This allows for swinging during grinding, enabling grinding of different positions on the workpiece. The power frame 313 is equipped with a grinding wheel 3134 and a motor that drives the grinding wheel 3134 to rotate, thus achieving a coordinated grinding effect.

[0089] like Figure 8 As shown, in this embodiment, the power frame 313 includes a power compartment 3131 and a protective shell 3132 installed on one side of the power compartment 3131. One end of the power compartment 3131 is disposed on the outer ring portion 3121 of the transmission gear. A grinding motor 3133 (which can be a servo motor) with its output shaft disposed in the protective shell 3132 is disposed inside the power compartment 3131, and a grinding wheel 3134 is disposed on the output shaft of the grinding motor 3133.

[0090] Specifically, the grinding wheel 3134 can be installed inside the protective shell 3132 of the grinding wheel 3134, while the grinding motor 3133 is installed inside the power compartment 3131. The output shaft of the grinding motor 3133 passes through the power compartment 3131 and the protective shell 3132 of the grinding wheel 3134, and the grinding wheel 3134 is mounted on the output shaft of the motor for driving. The outer ring 3121 of the transmission gear 312 is mounted on one side of the power compartment 3131, thus achieving synchronous rotation, so that the grinding wheel 3134 can swing and grind at different angles.

[0091] In this embodiment, the protective shell 3132 is provided with a clearance opening (not shown) facing the center hole of the fixed cylinder 41 to supply wax to the grinding wheel 3134 while ensuring the protective effect of the protective shell 3132. The frame 311 is provided with a receiving cavity 3117 for accommodating the rack structure 3111 and the transmission gear 312. The receiving cavity 3117 is provided with a cover plate 3118 that can be opened or closed. The design of the receiving cavity 3117 ensures that the mating structure between the rack structure 3111 and the transmission gear 312 is covered within the receiving cavity 3117, preventing the accumulation of external dust from affecting the meshing of the gear and rack, thus forming a protective effect on the gear and rack and providing good performance.

[0092] like Figure 3 and Figure 4 As shown, in this embodiment, the clamping mechanism 20 includes a clamping base 21 and a plurality of linkage seats 22 arranged side by side within the clamping base. The linkage seats 22 are rotatably disposed between the clamping base 21 and the clamping base 21. The number of linkage seats 22 is the same as the number of grinding units 31. A vertical shaft 221 arranged in a vertical direction and a horizontal shaft 222 arranged in a horizontal direction are provided in the linkage seat 22. A first rotating gear seat 211 connected to the linkage seat 22 is provided in the clamping base 21. The driving end of the vertical shaft 221 passes through the first rotating gear seat 211. A second rotating gear seat 212 is provided on the 11th axis, meshing with the gear of the vertical shaft 221; a gear pair 223 with a 90-degree power transmission direction is provided between the vertical shaft 221 and the horizontal shaft 222; a clamping member 224 for clamping the workpiece is provided on the shaft end of the horizontal shaft 222; a first transmission shaft 213 and a first rotary motor 23 for driving the first transmission shaft 213 to rotate are provided between two adjacent first rotating gear seats 211; a second transmission shaft 214 and a second rotary motor 24 for driving the second transmission shaft 214 to rotate are provided between two adjacent second rotating gear seats 212. The clamping member 224 can be a sleeve-type clamp to achieve sleeve clamping.

[0093] Specifically, the first rotary motor 23 and the second rotary motor 24 can be servo motors or rotary cylinders. In conjunction with the transmission shaft, a single servo motor can simultaneously drive the rotation of multiple vertical shafts 221, as well as the rotation of the horizontal shaft. Bearings are provided between the horizontal shaft 222 and the vertical shaft 221 and the linkage seat 22 to ensure the rotation of the shaft structure.

[0094] In use, the first rotary motor 23 drives the entire linkage seat 22 to rotate on the vertical shaft 221, while the second rotary motor 24 drives the clamping member 224 to rotate, giving the workpiece fixed on the clamping member 224 two degrees of rotational freedom. This, combined with the movement of the cross guide unit 11, ensures that the workpiece fixed on the clamping mechanism 20 has good flexibility, preventing dead angles during grinding and improving grinding quality.

[0095] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
