[0002] In modern industrial production, customers have increasingly higher requirements for equipment, and a single piece of equipment needs to perform multiple functions. In the glass processing industry, especially in the production of thick glass such as furniture glass, the processing process requires the use of large-diameter grinding wheels for edge grinding. After edge grinding, a smaller grinding head needs to be replaced for drilling. In the market, tool magazines are generally installed on machine tools. However, because the spindle power used for large-diameter grinding wheels is high and the speed is low, the effect of drilling may not be ideal. A high-speed spindle is required for drilling. Therefore, in the existing technology, edge grinding and drilling operations are generally carried out by two separate devices. This process requires repeated transfer and positioning of the workpiece, resulting in a large overall equipment size and low processing efficiency. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0030] Reference Figures 1 to 3As shown, this utility model discloses a dual-spindle Z-axis slide plate structure. In this embodiment, the dual-spindle Z-axis slide plate structure includes a first drive assembly 10, a spindle mounting plate 20, a grinding spindle 30, a second drive assembly 40, a drilling spindle slide plate 50, and a drilling spindle 60. The first drive assembly 10 has a first drive end, and the spindle mounting plate 20 is connected to the first drive end so that the spindle mounting plate 20 reciprocates in the vertical direction, that is, it realizes lifting and lowering motion in the Z-axis direction. Furthermore, the second drive assembly 40 is disposed on the outer surface of the spindle mounting plate 20. The second drive assembly 40 has a second drive end. The drilling spindle slide plate 50 is slidably mounted on the spindle mounting plate 20 and connected to the second drive end, so that the drilling spindle slide plate 50 reciprocates in the vertical direction. The edge grinding spindle 30 is fixedly mounted on the outer surface of the spindle mounting plate 20, and the drilling spindle 60 is fixedly mounted on the outer surface of the drilling spindle slide plate 50. The edge grinding spindle 30 and the drilling spindle 60 are arranged side by side.

[0031] Based on the above structure, we will explain in detail the working principle of the dual-spindle Z-axis sliding plate structure of this utility model. The first drive assembly 10 drives the spindle mounting plate 20 to reciprocate vertically, thereby driving the grinding spindle 30 to achieve lifting and lowering motion. A grinding wheel 301 is installed at the bottom end of the grinding spindle 30, allowing for the grinding of the workpiece. The grinding wheel 301 can be replaced to meet the needs of different processes. The second drive assembly 40 drives the drilling spindle sliding plate 50 to slide up and down on the spindle mounting plate 20, driving the drilling spindle 60 to achieve lifting and lowering motion. A drilling head is installed at the lower end of the drilling spindle 60 to drill holes in the workpiece. It should be noted that during the edge grinding process, the second drive assembly 40 retracts the drilling spindle 60 so that the horizontal height of the drilling head is higher than that of the grinding wheel 301; during the drilling process, the second drive assembly 40 moves the drilling spindle 60 downward so that the horizontal height of the drilling head is lower than that of the grinding wheel 301, thus avoiding mutual interference between the edge grinding spindle 30 and the drilling spindle 60. This dual-spindle Z-axis slide plate structure of the present invention designs one spindle for edge grinding and one for drilling. The two spindles are driven by different power mechanisms, enabling drilling operations after workpiece grinding, eliminating the need for repeated workpiece transfer and positioning, thus improving workpiece processing efficiency. By replacing the grinding wheel 301 or the drilling head, different processing requirements can be met.

[0032] Regarding the first driving component 10, combined with Figure 1 , Figure 2As shown, this utility model provides a specific embodiment in which the dual-spindle Z-axis slide plate structure further includes a fixed base plate 70; the first drive assembly 10 includes a lifting drive motor 101, a motor lead screw 102, a first linear guide rail 103, and a first slider 104; the lifting drive motor 101 is fixed to the outer surface of the fixed base plate 70, and one end of the motor lead screw 102 is connected to the motor shaft of the lifting drive motor 101; two first linear guide rails 103 are fixed side by side to the outer surface of the fixed base plate 70, and the first slider 104 is slidably disposed on the first linear guide rail 103, and the inner surface of the spindle mounting plate 20 is fixedly connected to the first slider 104; a lead screw nut (not shown in the figure) is also fixedly disposed on the inner surface of the spindle mounting plate 20, and the motor lead screw 102 passes through the lead screw nut. Therefore, the rotation of the lifting drive motor 101 can drive the motor lead screw 102 to rotate. Through the cooperation between the motor lead screw 102 and the lead screw nut, the spindle mounting plate 20 can slide on the first linear guide rail 103, thereby driving the grinding spindle 30 on the spindle mounting plate 20 to achieve lifting and lowering movement.

[0033] In addition, the first drive assembly 10 also includes a motor mounting base 105, which is fixed to the outer surface of the fixed base plate 70. The lifting drive motor 101 is mounted on the motor mounting base 105. A bearing seat (not shown in the figure) is also provided on the outer surface of the fixed base plate 70. This bearing seat contains a rotating bearing, and the other end of the motor lead screw 102 is connected to the rotating bearing. The design of the bearing seat and the rotating bearing improves the stability of the motor lead screw transmission.

[0034] Regarding the second driving component 40, in conjunction with Figure 1 , Figure 2As shown, this utility model provides a specific embodiment where the second drive assembly 40 includes a lifting cylinder 401, a drilling linear guide rail 402, and a second slider 403. The lifting cylinder 401 is fixedly installed on the outer surface of the spindle mounting plate 20, and the two drilling linear guide rails 402 are installed parallel to each other on the outer surface of the spindle mounting plate 20. The second slider 403 is slidably disposed on the drilling linear guide rail 402. The drilling spindle slide plate 50 is fixedly connected to the second slider 403, and the top end of the cylinder rod of the lifting cylinder 401 is connected to the slider of the drilling spindle 60. Additionally, the second drive assembly 40 also includes a cylinder fixing block 404, which is fixedly installed on the outer surface of the spindle mounting plate 20, and the lifting cylinder 401 is mounted on the cylinder fixing block 404. With this structure, driven by the lifting cylinder 401, the drilling spindle slide plate 50 can slide on the drilling linear guide rail 402, thereby driving the drilling spindle 60 on the drilling spindle slide plate 50 to achieve lifting and lowering motion. The drilling spindle 60 and the grinding spindle 30 are side by side, and both of them reciprocate in the vertical direction.

[0035] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model.
