Description

Technical Field

[0001] The utility model relates to the technical field of quartz product processing, in particular to a positioning tool for cutting a quartz tail flange. Background Art

[0002] Quartz is a mineral with high hardness, high temperature resistance and strong chemical stability. Its products have extremely high optical transparency and thermal stability and are often used in high-end optical instruments, semiconductor manufacturing and special lighting equipment. With the development of the semiconductor industry, the processing of quartz products has gradually matured.

[0003] Figure 1 The present invention shows a simple positioning tool used by most quartz tail flange cutting equipment on the market, including a cross bar 16 installed on a frame and movable forward and backward, a roller shaft 34 fixed at one end of the cross bar, and a positioning roller 4 rotatably sleeved on the roller shaft. When in use, the cross bar is pulled by manpower to adjust the distance between the positioning roller and the tool of the cutting equipment to the finished product size, and then the raw material tube 15 is moved forward and abutted against the positioning roller through the supply screw, and finally the tool is pressed down for cutting.

[0004] In the above structure, the positioning roller is directly pulled out and adjusted by manpower, which not only limits the adjustment accuracy and easily produces large deviations, but also requires frequent position corrections, which is inefficient. Especially when pursuing direct cutting of the quartz tail flange to the precise size of the finished product, it can only rely on repeated rough adjustments, and the operation process is cumbersome and it is difficult to ensure processing accuracy. In addition, during the cutting operation, once a deviation is found, there is no direct and effective means of fine-tuning, which limits the further improvement of the overall processing quality and production efficiency.

[0026] [Example 1]

[0027] Please refer to Figure 2-3 A positioning tool for cutting a quartz tail flange comprises a coarse adjustment cross bar 1 which is installed on a frame of a cutting device and can move forward and backward along the length direction of the frame. A vertical positioning base 2 is fixedly provided at one end of the coarse adjustment cross bar 1 facing the cutting tool. A moving base 3 is provided between the positioning base 2 and the cutting tool. A vertical positioning roller 4 is rotatably installed on the moving base 3. A fine adjustment structure is provided between the moving base 3 and the positioning base 2. The fine adjustment structure is used to drive the moving base 3 to move forward and backward relative to the positioning base 2 along the length direction of the frame for adjustment.

[0028] The above-mentioned fine-tuning structure includes two guide rods 5 fixed to the rear of the mobile base 3, and a threaded adjustment rod 6 is provided between the two guide rods 5, and the guide rods 5 and the adjustment rod 6 are parallel to the coarse adjustment cross bar 1. The rear end of the adjustment rod 6 is provided with an end for easy rotation by the user, and the front end of the adjustment rod 6 is rotatably connected to the mobile base 3 (bearings, retaining rings and other common structures in the field can be used). The positioning base 2 is provided with an anti-rotation guide hole that matches the guide rod 5 and an adjustment threaded hole that matches the adjustment rod 6. In this way, when it is necessary to fine-tune the positioning roller 4, it is only necessary to rotate the adjustment rod 6 in the forward or reverse direction to pull or push the mobile base 3 so that it is close to or away from the positioning base 2 along the axial direction of the guide rod 5 to achieve fine-tuning.

[0029] In order to prevent the positioning roller 4 from deviating during use, a locking threaded hole leading to the anti-rotation guide hole is opened inwardly on the side of the positioning base 2, and a locking bolt 7 that can abut inwardly on the guide rod 5 is provided in each locking threaded hole. In this way, after the fine adjustment is completed, the movable base 3 can be locked through the guide rod 5 by turning the locking bolt 7, so that the positioning roller 4 is locked and positioned.

[0030] In the above structure, the mobile base 3 includes an upper plate 31, a lower plate 32 and a vertical plate 33, the vertical plate 33 is connected to the rear of the upper plate 31 and the lower plate 32, a roller shaft 34 is vertically penetrated between the upper plate 31 and the lower plate 32, and the positioning roller 4 is rotatably mounted on the roller shaft 34. Figure 2 As shown, the guide rod 5 and the adjustment rod 6 are both connected to the rear side of the vertical plate 33 .

[0031] In the above structure, refer to Figure 3 The positioning roller 4 includes a rotating body 41 and a dust cover 42. The dust cover 42 covers the two ends of the rotating body 41, and a bearing 43 is provided between each dust cover 42 and the rotating body 41. The dust cover 42 can effectively prevent debris from invading the bearing 43 during the cutting process and causing bearing abnormality.

[0032] In order to further improve the locking effect, a locking threaded hole leading to the anti-rotation guide hole is also opened downward on the upper part of the positioning base 2, and a locking bolt 7 that can abut inwardly on the guide rod 5 is also provided in the locking threaded hole.

[0033] [Example 2]

[0034] Reference Figure 4-5 , Example 2 makes further improvements on the coarse adjustment cross bar 1 on the basis of Example 1, so that it can work more efficiently and accurately, specifically including: a mounting base 8 mounted on the frame of the cutting equipment, the mounting base 8 is provided with two anti-rotation support seats 9, and the coarse adjustment cross bar 1 is inserted into the anti-rotation support seats 9. The anti-rotation support seats 9 allow the coarse adjustment cross bar 1 to move forward and backward only along its own axis, while limiting its relative rotation (such as the cross section of the coarse adjustment cross bar 1 is rectangular, and the anti-rotation support seats 9 are arranged corresponding to it). An auxiliary locking member 10 that can abut against the coarse adjustment cross bar 1 inward is provided on each anti-rotation support seat 9, and a driving mechanism for driving the coarse adjustment cross bar 1 to move forward and backward along the length direction of the frame is provided on the mounting base 8. The auxiliary locking member 10 is used for positioning after coarse adjustment to prevent the coarse adjustment cross bar 1 from deviating due to the vibration of cutting. In this embodiment, the structure of the auxiliary locking member 10 is the same as the locking bolt 7 in Example 1.

[0035] In the above structure, the driving mechanism can adopt common structures such as bevel gear system and worm gear. In order to pursue the adjustment efficiency of the coarse adjustment cross bar 1, an acceleration structure is set in the driving mechanism in this embodiment. Specifically, the driving mechanism includes a lower rack 11 fixedly set between two anti-rotation support seats 9, an upper rack 12 is correspondingly provided on the upper coarse adjustment cross bar 1, and a driving gear 13 that matches the upper rack 12 and the lower rack 11 is correspondingly provided between the upper rack 12 and the lower rack 11. A driving device for driving the driving gear 13 to move forward and backward along the length direction of the frame is provided on one side of the lower rack 11. The driving device can be a driving cylinder 14 (or a driving oil cylinder). In this way, the coarse adjustment cross bar 1 can move twice the cylinder stroke per unit time, which not only increases the coarse adjustment range of the positioning roller 4 and adapts to diversified product structures, but also speeds up its adjustment speed and improves the overall work efficiency.

[0036] Working principle: The utility model is a positioning tool for cutting quartz tail flange. When in use, first visually determine the approximate target position of the positioning roller 4, and operate the output end of the driving cylinder 14 to extend, and quickly move the coarse adjustment cross bar 1 to the above-mentioned target position through the coordination of the gear rack, so that the distance between the positioning roller 4 and the cutting tool is close to the finished product size, and then the auxiliary locking piece 10 is screwed inward to lock it, and the coarse adjustment cross bar 1 is positioned, and then the adjustment rod 6 is rotated to slowly push or pull the mobile base 3 forward, and a measuring tool is used to measure the distance between the positioning roller 4 and the cutting tool. When it completely meets the finished product size, stop rotating, and screw the locking bolt 7 inward to position the mobile base 3. At this point, the positioning is completed, and the raw material tube can be moved forward and abutted against the positioning roller 4 through the supply screw, and the cutting tool is pressed down to cut the finished product.

[0037] The utility model realizes rapid positioning and fine adjustment of the positioning roller 4 by providing a coarse adjustment cross bar 1 and a fine adjustment structure, so that the positioning roller 4 can be adjusted in one step, effectively improving the adjustment efficiency and adjustment accuracy of the positioning roller 4, avoiding the errors and cumbersome steps caused by repeated coarse adjustment correction, and ensuring the processing accuracy of the product; the fine adjustment structure allows the positioning roller 4 to achieve a small forward and backward displacement. When in use, it is only necessary to loosen the locking bolt 7 and turn the adjusting rod to achieve fine adjustment of the front and rear position of the positioning roller 4 without stopping the machine, thereby further improving the overall processing quality and production efficiency of the product.

[0038] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
