Description

Technical Field

[0001] This utility model relates to the field of silicon rod feeding technology, specifically to a high-precision feeding platform for CNC machine tools. Background Technology

[0002] Photovoltaic industry production equipment, grinding and turning integrated machines, due to the special nature of their processing, usually require a feeding table to feed the crystal rods into the machine for processing.

[0003] The loading table is a fixed, integrated unit. When the crystal ingot surface has an inclination or the loading table plane has a height difference, it cannot automatically adjust to ensure the crystal ingot is on a horizontal line, resulting in uneven crystal ingots. This may lead to the scrapping of processed products. To ensure the quality of crystal ingot processing, the existing integrated fixed loading table structure lacks the ability to actively adjust its horizontal posture. When any factor exists, such as the ingot end face tilt angle or the height difference of the loading table, the support points of the crystal ingot are not equidistant from the processing reference plane after being placed on the loading table. The crystal ingot is fed into the processing area in a non-horizontal state, causing it to be uneven in the processing coordinate system. This initial posture error, including parallelism error and / or perpendicularity deviation, will be magnified many times over in the subsequent high-precision, high-feed grinding process, leading to the scrapping of processed products.

[0004] Therefore, it is necessary to invent a high-precision loading platform for CNC machine tools to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a high-precision loading table for CNC machine tools. This solves the problem that when using a fixed integrated loading table in actual use, if the crystal rod surface has a slope or there is a height difference on the loading table plane, it cannot automatically adjust to ensure that the crystal rod is on a horizontal line, resulting in uneven crystal rods and potentially scrapped processed products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-precision loading table for CNC machine tools includes a fixed base and a sliding base that is slidably connected to the fixed base.

The servo motor is fixedly installed on the outside of the mounting frame. The adjusting spindle is rotatably installed on the inside of the mounting frame via a bearing seat. The driven gear is sleeved on the outside of the adjusting spindle. The output end of the servo motor is connected to the drive gear, and the driven gear meshes with the drive gear. The synchronous adjusting block is sleeved on both ends of the adjusting spindle. A waist-shaped groove is opened on both sides of the synchronous adjusting block. A connecting shaft is fixedly installed at the end of the synchronous adjusting rod, and the connecting shaft slides inside the waist-shaped groove.

[0011] As a preferred embodiment of this utility model, the lateral angle adjustment assembly includes a sliding adjustment plate, an adjustment gear, a rack, and a second servo motor. The sliding adjustment plate is slidably mounted on the side of the mounting block, the rack is fixedly mounted on the inner side of the sliding adjustment plate, and the two ends of the sliding adjustment plate are provided with pressing end faces.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0022] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0023] This utility model provides, for example Figure 1-5 The high-precision loading table for CNC machine tools shown includes a fixed base 1 and a sliding base 2 slidably connected to the fixed base 1. A support component 3 is fixedly installed at the top of the sliding base 2. The support component 3 includes a mounting block 301. A slot is cut on one side of the mounting block 301, and an adjusting component 7 is rotatably installed in the slot. The adjusting component 7 includes a mounting frame 701. A clamping plate 5 is rotatably installed at the clamping end of the mounting frame 701. A longitudinal angle adjusting component is provided on the inner side of the mounting frame 701, and a transverse angle adjusting component is provided on one side of the mounting block 301. By setting the transverse and longitudinal angle adjusting components, when a large difference in the slope of the silicon block is detected during clamping, the transverse and longitudinal angles of the loading table can be adjusted based on the detection data, thereby adapting to silicon blocks of different specifications, improving the adaptability of the loading table, and reducing silicon block cutting losses.

[0024] A hinge block 501 is provided in the middle of the clamping plate 5, and the hinge block 501 is rotatably connected to the mounting frame 701. The clamping plate 5 rotates around the hinge block 501 and is pushed out by the ejector rod 706 on one side, so that the clamping plate 5 tilts to one side to achieve the purpose of longitudinal angle adjustment.

[0025] The longitudinal angle adjustment assembly includes a synchronous adjustment rod 704, a return spring 705, an ejector rod 706, and a longitudinal drive unit. Multiple ejector rods 706 are symmetrically arranged on both sides of the hinge block 501. The return spring 705 is sleeved on the outside of the ejector rod 706. The synchronous adjustment rods 704 are located on both sides of the hinge block 501 and are fixedly connected to each other. The return spring 705 is located inside the mounting frame 701. After adjustment, the force of the return spring 705 can restore the clamping plate 5 to a vertical state, facilitating the subsequent installation of the silicon block.

[0026] The longitudinal drive unit includes a servo motor 4, a drive gear 707, a driven gear 708, an adjusting spindle 709, and a synchronous adjusting block 710. The servo motor 4 is fixedly installed on the outside of the mounting frame 701. The adjusting spindle 709 is rotatably installed on the inside of the mounting frame 701 via a bearing seat. The driven gear 708 is sleeved on the outside of the adjusting spindle 709. The output end of the servo motor 4 is connected to the drive gear 707. The driven gear 708 meshes with the drive gear 707. The synchronous adjusting block 710 is sleeved on both ends of the adjusting spindle 709. The synchronous adjusting block 710 has a waist-shaped groove 712 on both sides. The end of the synchronous adjusting rod 704 is fixedly installed with a connecting shaft 711. The connecting shaft 711 slides inside the waist-shaped groove 712. By adjusting the settings of the main shaft 709, the synchronous adjustment blocks 710 at both ends can rotate synchronously to ensure the effect of angle adjustment. The opening of the waist-shaped groove 712 ensures that the synchronous adjustment rod 704 will not interfere with the synchronous adjustment block 710 during rotation.

[0027] The lateral angle adjustment assembly includes a sliding adjustment plate 302, an adjustment gear 303, a rack 304, and a servo motor 6. The sliding adjustment plate 302 is slidably mounted on the side of the mounting block 301, and the rack 304 is fixedly mounted on the inner side of the sliding adjustment plate 302. The sliding adjustment plate 302 has pressing end faces 305 at both ends. The two adjustment gears 303 mesh with the rack 304 respectively. The output end of the servo motor 6 is connected to one of the adjustment gears 303. When the silicon block at the detection point tilts along the length of the mounting block 301, the lateral angle adjustment assembly adjusts the tilt angle of the mounting frame 701, allowing the clamping plate 5 to fit against the silicon block, compensating for the lateral tilt and achieving adaptive adjustment of the loading platform.

[0028] One end face of the mounting frame 701 has a guide groove for the sliding adjustment plate 302 to slide. An adjustment curved surface 703 is also provided on the end face of the mounting frame 701. A pivot hole 702 is provided on the side of the mounting frame 701 corresponding to the adjustment gear 303. The adjustment curved surface 703 is symmetrically arranged on both sides of the pivot hole 702. By pressing the adjustment curved surface 703 with the pressing end face 305, the mounting frame 701 is offset to one side. The pivot hole 702 ensures that the mounting frame 701 remains in contact with the sliding adjustment plate 302, preventing the sliding adjustment plate 302 from separating from the mounting frame 701.

[0029] A rotating shaft is inserted into the rotating shaft hole 702, and both ends of the rotating shaft extend to the inner side of the mounting block 301. The top and bottom ends of the mounting frame 701 can be lubricated or have guide balls added to reduce friction and make angle adjustment easier.

[0030] This invention uses servo motor 4 and servo motor 6 to drive the longitudinal angle adjustment component and the transverse angle adjustment component, respectively. When the crystal ingot clamped by the loading table has a slant, the servo motor can adjust the deviation position by adjusting the range of the crystal ingot, thereby adjusting the position and angle of the clamping plate 5. This improves the accuracy of the loading table and solves the problems of quality abnormalities caused by height differences when the crystal ingot is slanted and the loading table is clamped. It also solves the problem of the difficulty in processing the slanted crystal ingot. At the same time, the adaptive clamping setting can reduce the size of the blank crystal ingot cut in the previous process, thereby reducing silicon consumption.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
