Description

Technical Field

[0001] This utility model relates to a positioning mechanism for a double-head CNC silicon rod cutting machine, and particularly to a positioning mechanism for a double-head CNC silicon rod cutting machine applied in the field of cutting machines. Background Technology

[0002] The dual-head CNC silicon rod cutting machine is a high-efficiency precision machining equipment based on CNC technology, mainly used for cutting silicon rods in the photovoltaic, semiconductor and other fields. Its core feature lies in its dual-head synchronous cutting design, combined with a CNC system to achieve automated operation, ensuring processing efficiency and precision.

[0003] The core functions of a dual-head CNC silicon rod cutting machine are: the dual-head design enables synchronous cutting or alternating processing at both ends, significantly improving processing efficiency per unit time; cutting parameters can be programmed and set through the CNC system, with errors controlled within 0.1mm, meeting the high precision requirements of silicon rod processing; it supports angle adjustment (e.g., 45°-90° range) and irregular shape cutting, adapting to the processing requirements of silicon rods of different specifications; and it integrates automatic positioning and programmed cutting processes, reducing manual intervention and lowering operational complexity.

[0004] When cutting materials, the cutting operator uses the cutting mechanism to clamp and position the workpiece. However, the existing positioning mechanism of the double-head CNC silicon rod cutting machine is mostly fixed in angle, so it is difficult to clamp and position workpieces of different shapes from multiple angles, and its applicability is not ideal. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that the positioning mechanism of the existing double-head CNC silicon rod cutting machine is difficult to clamp and position workpieces of different shapes from multiple angles because its angle is mostly fixed.

[0006] To solve the above problems, this utility model provides a positioning mechanism for a double-head CNC silicon rod cutting machine, including a cutting machine body, a cutting box fixedly connected inside the cutting machine body, a cutting mechanism fixedly connected to the inner top wall of the cutting box, an electric push rod fixedly connected to a pair of inner side walls of the cutting box, a connecting shaft fixedly connected to the telescopic end of the electric push rod, a pair of rectangular plates rotatably sleeved on the outer end of the connecting shaft, a common clamping plate fixedly connected to the side ends of the pair of rectangular plates, an installation groove opened at the adjacent ends of the pair of rectangular plates, an adjustment groove opened on the inner top wall of the installation groove, a lifting tube movably inserted inside the adjustment groove, a rectangular block fixedly connected to the lower end of the lifting tube, a limit tube fixedly connected to the lower end of the rectangular block, and a plurality of limit grooves movably inserted with the limit tube opened on the outer end of the connecting shaft.

[0007] In the aforementioned positioning mechanism for a double-headed CNC silicon rod cutting machine, it can clamp and position workpieces of different shapes from multiple angles, and its application range is relatively wide.

[0008] As a further improvement of this application, there is a gap between the lower ends of both the clamping plate and the rectangular plate and the inner bottom wall of the cutting box.

[0009] As a further improvement of this application, a spring is fixedly connected between the rectangular block and the mounting groove, and the spring is in a contracted state in the initial state.

[0010] As a further improvement of this application, a lifting block is fixedly connected to the side end of the rectangular block, and the outer end of the lifting block is engraved with anti-slip texture.

[0011] As a further improvement of this application, the diameter of the spring is larger than the diameter of the adjusting groove, and the outer end of the rectangular block is slidably connected to the inner wall of the mounting groove.

[0012] As another improvement of this application, a dust collection hole is provided on the inner bottom wall of the cutting box, and a rectangular groove communicating with the dust collection hole is provided on the side end of the cutting box. A dust collection box is movably inserted into the rectangular groove, and a stop bar is fixedly connected to the inner bottom wall of the cutting box.

[0013] As a further improvement to this application, a handle is fixedly connected to the side of the dust collection box, and the dust collection box is magnetically connected to the rectangular groove through a magnetic coating.

[0014] In summary, when clamping and positioning a workpiece, the rectangular block can be moved upwards according to the workpiece's shape and the suitable angle for fixing until the lower end of the limiting tube moves out of the limiting groove. Then, the clamping plate is rotated up and down to adjust its angle. Finally, under the action of the spring force, it will push the rectangular block and the limiting tube downwards, thereby fixing the connecting shaft. Finally, the electric push rod is activated to push the clamping plate to apply force to the workpiece, thus clamping and positioning the workpiece. Therefore, this mechanism can clamp and position workpieces of different shapes at multiple angles, and its application range is wide. Attached Figure Description

Detailed Implementation

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figure 1-5 A positioning mechanism for a double-headed CNC silicon rod cutting machine is shown, including a cutting machine body 1. A cutting box 2 is fixedly connected inside the cutting machine body 1. A cutting mechanism 3 is fixedly connected to the inner top wall of the cutting box 2. Electric push rods 18 are fixedly connected to a pair of inner side walls of the cutting box 2. A connecting shaft 4 is fixedly connected to the telescopic end of the electric push rod 18. A pair of rectangular plates 5 are rotatably sleeved on the outer end of the connecting shaft 4. The same clamping plate 6 is fixedly connected to the side ends of the pair of rectangular plates 5. A mounting groove 7 is opened at the end of the pair of rectangular plates 5 that is close to each other. An adjustment groove is opened on the inner top wall of the mounting groove 7. A lifting tube 8 is movably inserted into the adjustment groove. A rectangular block 9 is fixedly connected to the lower end of the lifting tube 8. A limit tube 10 is fixedly connected to the lower end of the rectangular block 9. A plurality of limit grooves 11 are opened on the outer end of the connecting shaft 4 and are movably inserted into the limit tube 10.

[0026] The lower ends of the clamping plate 6 and the rectangular plate 5 are both separated from the inner bottom wall of the cutting box 2. A spring 12 is fixedly connected between the rectangular block 9 and the mounting groove 7. In the initial state, the spring 12 is in a contracted state. A lifting block is fixedly connected to the side end of the rectangular block 9. The outer end of the lifting block is engraved with anti-slip texture. The diameter of the spring 12 is larger than the diameter of the adjusting groove. The outer end of the rectangular block 9 is slidably connected to the inner wall of the mounting groove 7.

[0027] The application is used in the following steps:

[0028] Step 1: When using, place the workpiece in the cutting box 2, so that it is directly below the cutting mechanism 3 and between a pair of clamping plates 6. Then start the electric push rod 18 to push the clamping plates 6 to apply force to the workpiece, so as to clamp and position the workpiece.

[0029] Step 2: When clamping and positioning the workpiece, the rectangular block 9 can be moved upward according to the shape of the workpiece and the angle suitable for fixing, so that it pushes the lifting tube 8 into the interior of the adjustment groove and continues to compress the spring 12. At the same time, the limiting tube 10 will move upward along with the rectangular block 9 until the lower end of the limiting tube 10 moves out of the limiting groove 11, so as to release the limiting effect of the limiting tube 10 on the connecting shaft 4.

[0030] Then, the clamping plate 6 is rotated up and down, causing the rectangular plate 5 to rotate together on the connecting shaft 4, thereby adjusting the angle of the clamping plate 6. Finally, under the action of the spring force 12, it will push the rectangular block 9 and the limiting tube 10 to move down, so that the lower end of the limiting tube 10 enters the corresponding limiting groove 11, thereby fixing the connecting shaft 4. Finally, the electric push rod 18 is activated to push the clamping plate 6 to apply force to the workpiece, so as to clamp and position the workpiece. Therefore, this mechanism can clamp and position workpieces of different shapes at multiple angles, and its application range is wide.

[0031] Second implementation method:

[0032] This embodiment adds the following structure based on the first embodiment, while the rest remains the same as the first embodiment, as detailed below:

[0033] Figure 6 The cutting box 2 has a dust collection hole 13 on its inner bottom wall and a rectangular groove 14 communicating with the dust collection hole 13 on its side. A dust collection box 15 is movably inserted into the rectangular groove 14. A stop bar 16 is fixedly connected to the inner bottom wall of the cutting box 2. A handle is fixedly connected to the side of the dust collection box 15. The dust collection box 15 is magnetically connected to the rectangular groove 14 through a magnetic coating 17.

[0034] After cutting is completed, the debris generated during the cutting process needs to be swept into the dust collection hole 13, so that the debris can fall into the dust collection box 15 through the dust collection hole 13. Finally, the dust collection box 15 is removed from the rectangular groove 14 and the debris is cleaned. Therefore, this mechanism facilitates the collection and cleaning of cutting debris, and the baffle 16 can block the cutting debris when cleaning, making it difficult for it to be moved out of the cutting box 2.

[0035] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
