[0002] Glass edging equipment is one of the most widely used mechanical devices in glass processing, and its main function is to smooth the edges and corners of glass.

[0003] In the prior art, for example, the automatic glass edge grinding machine disclosed in CN213615769U describes that: a fixed frame is provided, and a grinding roller is provided inside the fixed frame. The grinding roller can move along a rectangular trajectory along the movable groove in the fixed frame, and can rotate axially during the movement. In this way, the rotating grinding roller can grind the edge of the glass. With the displacement of the rectangular trajectory, the four sides of the glass can be continuously ground. Thus, there is no need to rotate the glass multiple times during grinding, the degree of automation is high, the work efficiency is greatly improved, and the practicality is strong.

[0004] In actual use, the track of the above device is fixed, so the device can only grind glass of a single size and cannot change the shape and size of its grinding track according to different glass sizes; and the glass needs to be placed inside the device before grinding, but the glass is prone to displacement, that is, the device lacks a positioning structure inside. Utility Model Content

[0005] Technical problems to be solved

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Reference Figure 1-4 The first embodiment of this utility model provides an automatic glass edge grinding machine, including a base 1, a limiting rod 11 fixedly connected to the base 1, a disc on the upper side of the limiting rod 11 for engaging inside the bearing plate 12, so that the bearing plate 12 can rotate around the limiting rod 11, the bearing plate 12 is provided on the upper side of the limiting rod 11, and a top plate 13 is fixedly connected to the upper side of the base 1, the top plate 13 being fixedly connected to the base 1 through a column;

[0030] It also includes a positioning structure set in the base 1;

[0031] The positioning structure includes a lead screw 21 rotatably connected to the base 1, the lead screw 21 being set in a slot in the base 1, one end of the lead screw 21 being fixed to a first motor 22, and the other end being rotatably connected to the base 1, the first motor 22 being mounted on the lead screw 21, two threaded sleeves 23 being threadedly connected to the lead screw 21, the threads in the two threaded sleeves 23 being reverse threads, that is, when the lead screw 21 rotates, the two threaded sleeves 23 being brought closer to each other or moved away from each other, a positioning rod 24 fixed on the threaded sleeve 23, a support rod 25 fixed on the lower side of the positioning rod 24, the support rod 25 having rollers 28 inside for supporting the positioning rod 24 to maintain a certain height movement on the base 1, and a mounting slot 26 being opened on the positioning rod 24 for mounting the grinding structure.

[0032] The positioning rod 24 has a sliding groove 27, which is used for sliding connection of the connecting plate 39 in the grinding structure. The inner side of the support rod 25 is provided with a roller 28.

[0033] A cylinder telescopic rod 14 is fixedly connected to the top plate 13. A round pad 15 is fixedly connected to the lower side of the cylinder telescopic rod 14. The round pad 15 can fix the glass so that it will not move during processing. A grinding structure is provided on the inner side of the positioning rod 24.

[0034] During use, the glass is first placed on the support plate 12, with the two parallel sides of the glass roughly parallel to the positioning rod 24. Then, the first motor 22 is started to drive the lead screw 21 to rotate. The rotation of the lead screw 21 will cause the threaded sleeve 23 threaded to the lead screw 21 to move. The two threaded sleeves 23 move towards each other until they contact the grinding structure on the positioning rod 24, which is fixedly connected to the threaded sleeve 23, and fit against the glass. Then the first motor 22 is stopped. At this time, the positioning of the two sides of the glass is completed. Because the initial positions of the two threaded sleeves 23 are the same and the movement amplitude is the same, the glass can be positioned in the middle of the support plate 12, so that the subsequent grinding will not be offset. During the process, the support rod 25 provides support force, while the roller 28 makes the movement of the positioning rod 24 smoother and avoids the resistance causing the two threaded sleeves 23 to have different displacements. During the grinding process, the cylinder telescopic rod 14 needs to be activated to extend so that the round pad 15 presses the glass before the grinding process can begin.

[0035] When the other two sides of the glass need to be processed, the first motor 22 needs to be started to rotate in the opposite direction so that the threaded sleeves 23 are far apart from each other, so that they do not affect the rotation of the glass. The bearing plate 12 rotates 90°, and the first motor 22 is started again to position the glass with the positioning rod 24. Then the cylinder extension rod 14 is started to press the round pad 15 against the glass, and then the subsequent grinding process begins.

[0036] Example 2

[0037] Reference Figure 1-6 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the grinding structure includes a rack 31 disposed inside the positioning rod 24, the rack 31 being fixed in the inner wall of the mounting groove 26, a displacement gear 32 disposed on one side of the rack 31, the displacement gear 32 meshing with the rack 31, a first transmission gear 33 fixed on the upper side of the displacement gear 32, the first transmission gear 33 being fixedly connected to the displacement gear 32 via a shaft, a second transmission gear 34 disposed on one side of the first transmission gear 33, the second transmission gear 34 meshing with the first transmission gear 33, and a grinding wheel 35 fixed on the lower side of the second transmission gear 34, the grinding wheel 35 being fixedly connected to the second transmission gear 34 via a shaft.

[0038] A first bevel gear 36 is fixedly connected to the upper side of the first transmission gear 33. The first bevel gear 36 is fixedly connected to the first transmission gear 33 through a shaft. A second bevel gear 37 is provided on one side of the first bevel gear 36. The first bevel gear 36 and the second bevel gear 37 mesh.

[0039] A second motor 38 is provided on one side of the second bevel gear 37. The second motor 38 can directly drive the second bevel gear 37 through the shaft. A connecting plate 39 is provided on the upper side of the second transmission gear 34. The second transmission gear 34 and the grinding wheel 35 are rotatably connected inside the two connecting plates 39 through the shaft. The connecting plates 39 can slide in the slide groove 27.

[0040] During use, when polishing is required, the second motor 38 is started. The second motor 38 will drive the second bevel gear 37 to rotate. Because the first bevel gear 36 and the second bevel gear 37 are meshed, and the first bevel gear 36 is fixedly connected to the first transmission gear 33 and the displacement gear 32 through the shaft, the rotation of the second bevel gear 37 drives the first bevel gear 36, the first transmission gear 33, and the displacement gear 32 to rotate at the same angular velocity. Among them, the first transmission gear 33 and the second transmission gear 34 are meshed, which can drive the polishing wheel 35, which is fixedly connected to the second transmission gear 34, to rotate, thereby polishing the glass. During the process, the displacement gear 32 and the rack 31 are meshed, so that the whole device can rotate and move at the same time. That is, the polishing wheel 35 polishes and moves at the same time. The second motor 38 has a carriage that can move the second motor 38 along the positioning rod 24. The carriage on the second motor 38 has an extended shaft that is sleeved on the shaft on the lower side of the first bevel gear 36, so the position between the first bevel gear 36 and the second bevel gear 37 does not change and always remains meshed.

[0041] After one side is polished, the polishing structure reaches the other side of the positioning rod 24. Then, the second motor 38 is rotated in the opposite direction to make the polishing structure move in the opposite direction to complete the second polishing process.

[0042] The remaining structure is the same as that in Example 1.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
