Of course, they are only examples and are not intended to limit the present invention.

[0036] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0037] Example

[0038] In the prior art, a precision engraving machine is usually used to process circular glass. However, the commonly used precision engraving machine integrates multiple processing modes and multiple processing functions, resulting in complicated procedures and a long time for processing the diameter of circular glass. At the same time, the manufacturing and maintenance costs of the precision engraving machine itself are relatively high. It is not very appropriate to use the precision engraving machine alone in the diameter processing process of circular glass, which will cause problems of high cost and low efficiency.

[0039] This embodiment provides a grinding machine for processing the diameter of circular glass. The grinding machine is specially designed to use a grinding wheel for grinding according to the different diameters required for circular glass processing. It has a simpler structure and process, can improve processing efficiency, and reduce equipment and maintenance costs. Figure 1-Figure 6 The grinding machine mainly includes: a stand 100, a workbench 200 slidably arranged on the stand 100, and a frame 300 arranged at the other end of the stand 100.

[0040] The stand 100 is used to set the positions of the workbench 200 and the rack 300, and to provide a movable space for the workbench 200. Figure 1 , Figure 2As shown in the figure, the stand 100 is roughly in the shape of a relatively flat rectangular parallelepiped, and four legs 110 are arranged at the four corners of the lower surface of the stand 100 for supporting and fixing the entire grinding machine; a first groove 120 is arranged in the middle of the upper surface of the stand 100. The first groove 120 is mainly used to set the sliding mechanism 220, which is arranged between the stand 100 and the workbench 200 to drive the linear movement of the workbench 200. The sliding mechanism 220 of this embodiment mainly includes a first screw rod 221 and a first nut seat 223 arranged in the first groove 120, a first motor 224 arranged on a side surface of the stand 100, and a first mounting plate 226 arranged above the first groove 120. Among them, the first screw rod 221 is rotatably arranged in the first groove 120 at the positions near both ends through the bearing seat, and one end of the first screw rod 221 is connected to the output end of the first reducer 225 of the first motor 224 through the first coupling 222, and the first motor 224 and the first reducer 225 are both arranged on the side of the stand 100 close to the frame 300. At the same time, the middle part of the first screw rod 221 is sleeved with a first nut seat 223. The inner surface of the first nut seat 223 is threadedly connected with the outer side of the first screw rod 221, and the upper part of the first nut seat 223 is connected with the middle part of the lower surface of the first mounting plate 226. In addition, two first slide seats 227 are arranged on the upper surface of the stand 100 and located at the positions on both sides outside the first groove 120. The two first slide seats 227 are arranged parallel to the first screw rod 221, and two groups of first sliders 228 are arranged on both sides of the lower surface of the first mounting plate 226. The bottoms of the first sliders 228 are all concave inwards and are slidably sleeved on the first slide seats 227. Therefore, when the first motor 224 is working, the first mounting plate 226 can be driven to translate along the two first slide seats 227 through the first screw rod 221 .

[0041] The workbench 200 is arranged above the first mounting plate 226, and is used to carry the circular glass processing piece and can drive the rotation of the processing piece. The workbench 200 includes an external shell 240 and an internal first rotating mechanism 210. Among them, the shell 240 is roughly in the shape of a rectangular parallelepiped, and its interior is hollow. A circular mounting port is arranged on the upper surface for mounting the first rotating mechanism 210. The middle part where the first rotating mechanism 210 is connected to the circular mounting port is the second reducer 212. The second motor 211 is connected to the input end of the lower part of the second reducer 212. The second motor 211 is located inside the shell 240. The side of the shell 240 is also provided with heat dissipation holes to assist the second motor 211 in heat dissipation. At the same time, the upper output end of the second reducer 212 extends to the outside of the shell 240, and is connected to a support plate 213. The support plate 213 is roughly circular and horizontally arranged for placing circular glass processing pieces. When the second motor 211 rotates, the support plate 213 can be driven to rotate around the center, thereby driving the workpiece placed on the support plate 213 to rotate.

[0042] At the same time, in order to maintain the stability of the workpiece during rotation, a cylinder mounting frame 230 is provided above the first mounting plate 226 and at a position on one side of the workbench 200. The cylinder mounting frame 230 is roughly in the shape of an L-shaped square tube. The vertical portion of the cylinder mounting frame 230 maintains a certain distance from the workbench 200 to avoid affecting the placement of the circular glass workpiece on the workbench 200. The horizontal portion of the cylinder mounting frame 230 extends from the upper end of the vertical portion toward the center of the workbench 200. The horizontal portion of the cylinder mounting frame 230 is close to the center of the workbench 200. A lifting cylinder 231 is provided at one end of the center, and the telescopic rod of the lifting cylinder 231 is vertically downward and is arranged directly opposite to the center of the support plate 213 below, so that the telescopic rod of the lifting cylinder 231 is colinear with the rotation axis of the first rotating mechanism 210, and the lower end of the telescopic rod of the lifting cylinder 231 is connected to a pressure plate 232 through an ejector pin, and the ejector pin is inserted into the upper surface of the pressure plate 232. The lower surface of the pressure plate 232 can press the workpiece below, and the pressure plate 232 can be rotated relative to the telescopic rod of the lifting cylinder 231 through the ejector pin to adapt to the rotation of the workpiece below. In one or more other embodiments, the rotation connection between the pressure plate 232 and the lifting cylinder 231 can also be replaced by a bearing or other type of ejector pin instead of an ejector pin.

[0043] The frame 300 of this embodiment is used to set a grinding wheel 320 to grind the outer edge of a circular glass workpiece. The frame 300 is roughly in the shape of a rectangular parallelepiped and is vertically arranged at one end of the upper surface of the stand 100. On the side of the frame 300 facing the workbench 200, the position near the top is convex and is provided with a second rotating mechanism 310, and a lifting mechanism 330 is arranged between the second rotating mechanism 310 and the frame 300. Among them, the convex part of the top of the frame 300 is provided with a second groove 340 in a vertical direction, and the second screw rod 331 of the lifting mechanism 330 is arranged in the second groove 340, and the position of the second screw rod 331 near both ends is rotatably connected to the inner side surface of the second groove 340 through a bearing seat. The upper part of the lifting mechanism 330 is a third motor 334 and a third reducer 335, the input end of the third reducer 335 is connected to the output end of the third motor 334 above, and the input end of the third reducer 335 is connected to the upper end of the second screw rod 331 below. In addition, the middle of the second screw rod 331 is connected to the second mounting plate 336 through the sleeved second nut seat 333. The second mounting plate 336 is vertically arranged. Two sets of second sliders 338 are arranged on the side of the second mounting plate 336 close to the frame 300, and two second slide seats 337 are arranged in the vertical direction on both sides outside the second groove 340 on the frame 300. Several second sliders 338 are slidably sleeved on the second slide seats 337, so that the third motor 334 can drive the second mounting plate 336 to rise and fall when working. At the same time, the fourth motor 311 of the second rotating mechanism 310 is connected to the second mounting plate 336, and the output end of the fourth motor 311 is connected to the input end of the fourth reducer 312 below, and the output end of the fourth reducer 312 is downwardly connected to the grinding wheel 320 for grinding the edge of the workpiece.

[0044] A specific working method of this embodiment is:

[0045] Before use, the lifting cylinder 231 controls the pressure plate 232 to rise, and the circular glass workpiece to be processed is placed on the support plate 213 of the workbench, and the center of the circular glass workpiece is aligned with the rotation axis of the support plate 213; then, the lifting cylinder 231 controls the pressure plate 232 to be lowered, and the circular glass workpiece below is pressed tightly against the support plate 213; then, the second motor 211 and the fourth motor 311 are started to respectively drive the circular glass workpiece and the grinding wheel 320 on the support plate 213 to rotate, and the two rotate in opposite directions (i.e., one is counterclockwise). , the other clockwise) and then start the first motor 224 to control the sliding mechanism 220 to adjust the distance between the circular glass processing piece and the grinding wheel 320. On the one hand, the two can be brought close to start the grinding operation, and on the other hand, the required circular glass processing pieces of different diameters can be processed by freely adjusting the distance between the two. When the height of the grinding wheel 320 needs to be adjusted due to the different thickness of the circular glass processing piece, the fourth motor 311 can be started to control the lifting mechanism 330 to adjust the height difference between the circular glass processing piece and the grinding wheel 320.

[0046] In this embodiment, the grinding machine drives the circular glass processing piece and the grinding wheel 320 to rotate in opposite directions by setting a first rotating mechanism 210 on the workbench 200 and a second rotating mechanism 310 on the frame 300, and then cooperates with the sliding mechanism 220 on the stand 100 to adjust the distance between the workbench 200 and the frame 300 on the stand 100, so that the circular glass processing piece and the grinding wheel 320 are in contact for grinding, and the distance between the circular glass processing piece and the grinding wheel 320 can be freely adjusted, so that circular glass of the required diameter can be processed conveniently and quickly, and the overall equipment structure and operation are simple, achieving cost reduction and efficiency improvement, and solving the problems in the prior art that the process required for the precision engraving machine to process circular glass is complicated, time-consuming, and the manufacturing and maintenance costs are high, while the lathe has poor adaptability and insufficient precision in processing circular glass.

[0047] At the same time, in this embodiment, a lifting mechanism 330 is provided so that the height difference between the circular glass processing piece and the grinding wheel 320 can be adjusted, so that circular glasses of different thicknesses can be processed conveniently and quickly.

[0048] In addition, in this embodiment, a spray mechanism (not shown in the figure) facing the grinding wheel 320 is provided on the frame 300 for spraying grinding fluid to reduce dust and improve grinding efficiency. A mesh plate 130 is also laid on the upper surface of the stand 100 and located on both sides of the two first slides 227. The mesh plate 130 is connected to the internal pipeline of the stand 100 and is used to receive the grinding fluid flowing downward during the grinding process. In addition, two water tanks 140 are provided in the first groove 120 and located on both sides of the first coupling 222 of the first screw rod 221. The outward side of the two water tanks 140 is connected to the internal pipeline of the stand 100, so that the grinding fluid received by the mesh plates 130 on both sides can be collected and stored. At the same time, glass baffles 150 are also provided on the upper surface of the stand 100 and on both sides outside the mesh plate 130. Two glass baffles 150 are provided on each side to prevent glass chips generated during the grinding process from splashing. The glass baffles 150 are detachably inserted on the upper surface of the stand 100 to facilitate replacement. Furthermore, a hook 350 is also provided on the outer side of the rack 300 near the top. The hanging contact surface of the hook 350 is relatively wide and is used to hang spare glass baffles 150. A hanging opening 152 is provided near one end of the glass baffle 150. The hanging opening 152 is adapted to the hook 350, thereby making full use of the shape of the rack 300 and realizing the storage of spare parts of the glass baffle 150, which is more convenient and quick when replacement is needed.

[0049] Preferably, the first motor 224 and the third motor 334 in this embodiment are both servo motors to achieve precise distance control. At the same time, the first coupling 222 and the second coupling 332 in this embodiment are both preferably plum blossom couplings, so as to compensate for the relative offset of the two shafts and enhance shock absorption, wear resistance and buffering performance.
