[0002] When machining end faces, lengths, or welding workpieces on a conventional lathe, the workpiece needs to be measured and corrected multiple times to achieve the final dimensional requirements. During the process, the operator needs to frequently adjust the tool, which increases the error rate. If each workpiece is produced in multiple batches, and the technical requirements include long steps, equal height of the end face and total length, or a specific length, the operator's machining efficiency will be very low, workpiece quality assurance will be very difficult, and the rate of defects and scrap will increase. Therefore, it is necessary to design an end face positioning device for welding circular punches to solve the problems in the existing technology. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, such as Figures 1-4 As shown, a circular punch welding end face positioning device includes a lathe headstock 12 and a positioning component 2 disposed within the lathe headstock 12. A machine tool bed 1 is disposed at the bottom end of the lathe headstock 12. A guide rail 11 is disposed on the upper surface of the machine tool bed 1 near the lathe headstock 12. An adapter plate 13 is bolted to the outer wall of the lathe headstock 12 near the guide rail 11. A three-jaw chuck 14 is bolted to the outer wall of the adapter plate 13. A workpiece 15 is disposed on the inner wall of the three-jaw chuck 14. An anti-vibration component 3 is disposed on the inner wall of the lathe headstock 12 near the adapter plate 13.

[0024] In this embodiment, the workpiece 15 is self-centered and clamped by the three-jaw chuck 14, and then the end of the workpiece 15 is pressed by the positioning component 2, which facilitates subsequent processing. When the same workpiece 15 needs to be processed later, there is no need to perform tool setting again. During the processing, the anti-vibration component 3 can ensure the stability of the positioning component 2 and prevent the positioning component 2 from shifting due to vibration during the processing.

[0025] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the positioning assembly 2 includes a positioning rod 21. The end of the positioning rod 21 near the three-jaw chuck 14 is in close contact with one end of the workpiece 15. An adjusting sleeve 22 is slidably connected to the outer wall of the positioning rod 21 near the lathe headstock 12. The outer wall of the adjusting sleeve 22 is threadedly connected to the inner wall of the lathe headstock 12. The positioning rod 21 is fixed by the threaded connection between the adjusting sleeve 22 and the lathe headstock 12. Then, the position of the positioning rod 21 is adjusted again so that the end of the positioning rod 21 can be in close contact with the end of the workpiece 15. Then, the workpiece 15 can be processed.

[0026] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the adjusting sleeve 22 is threadedly connected to the inner wall of the lathe headstock 12 with a first limiting bolt 23. The outer wall of the first limiting bolt 23 penetrates the outer wall of the adjusting sleeve 22 and contacts the inner wall of the positioning rod 21. By loosening the first limiting bolt 23, the first limiting bolt 23 is no longer pressed against the inner wall of the positioning rod 21. Then the adjusting sleeve 22 can be pushed to slide on the outer wall of the positioning rod 21. When the adjusting sleeve 22 is in the correct position, the first limiting bolt 23 can be tightened again.

[0027] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the positioning rod 21 has a strip groove on the outer wall near the lathe headstock 12, and the width of the strip groove is 10-20mm larger than the diameter of the first limiting bolt 23. This way, when the outer wall of the first limiting bolt 23 enters the inner wall of the positioning rod 21, interference can be avoided as much as possible.

[0028] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the inner sidewall of the adjusting sleeve 22 is symmetrically provided with a first limiting block 24. The outer wall of the first limiting block 24 is slidably connected to the inner wall of the positioning rod 21. The positioning rod 21 has a sliding groove that matches the first limiting block 24 on the outer wall near the lathe work headstock 12. The movement of the adjusting sleeve 22 is limited by the first limiting block 24, so that the adjusting sleeve 22 can only move horizontally on the outer wall of the positioning rod 21 and cannot rotate. This makes it more convenient to fix the adjusting sleeve 22 with the first limiting bolt 23.

[0029] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the anti-vibration component 3 includes an anti-vibration balance sleeve 31. The outer wall of the anti-vibration balance sleeve 31 is slidably connected to the inner wall of the lathe work headstock 12, and the inner wall of the anti-vibration balance sleeve 31 is slidably connected to the outer wall of the positioning rod 21. The anti-vibration balance sleeve 31 can absorb the vibration force generated when the lathe is working, thereby preventing the vibration from affecting the positioning rod 21 and causing it to loosen its restriction on the workpiece 15.

[0030] In an optional embodiment, such as Figure 2 and Figure 4As shown, the inner wall of the shock-absorbing balance sleeve 31 is threaded with a second limiting bolt 32. The outer wall of the second limiting bolt 32 penetrates the outer wall of the shock-absorbing balance sleeve 31 and contacts the inner wall of the positioning rod 21. The positioning rod 21 has a strip groove on the outer wall near the adapter plate 13, and the width of the strip groove is 10-20mm larger than the diameter of the second limiting bolt 32. Whether the second limiting bolt 32 contacts the inner wall of the positioning rod 21 or not, the sliding of the shock-absorbing balance sleeve 31 on the outer wall of the positioning rod 21 can be controlled.

[0031] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the inner wall of the shock-absorbing balance sleeve 31 is symmetrically provided with second limiting blocks 33. The outer wall of the second limiting block 33 is slidably connected to the inner wall of the positioning rod 21. The outer wall of the positioning rod 21 near the adapter plate 13 is provided with a sliding groove that matches the second limiting block 33. When the shock-absorbing balance sleeve 31 slides on the outer wall of the positioning rod 21, the second limiting block 33 restricts the shock-absorbing balance sleeve 31, so that the second limiting block 33 can only move horizontally and will not rotate when it moves, thereby facilitating the second limiting bolt 32 to restrict the shock-absorbing balance sleeve 31.

[0032] The above embodiment discloses an end face positioning device for welding a circular punch. When the workpiece 15 needs to be processed, it is first self-centered and clamped by a three-jaw chuck 14. The clamping position of the workpiece 15 is defined by the axial position scale or electronic ruler of the machine tool. Then, based on the clamping position of the workpiece 15, the positions of the adjusting sleeve 22 and the anti-vibration balance sleeve 31 on the outer wall of the positioning rod 21 are adjusted. By loosening the first limiting bolt 23, it is no longer pressed against the inner wall of the positioning rod 21. Then, the adjusting sleeve 22 can be pushed, causing it to slide on the outer wall of the positioning rod 21. Once the adjusting sleeve 22 is properly positioned, the first limiting bolt 23 can be tightened again. During the movement of the adjusting sleeve 22, the first limiting block 24 restricts the direction of movement of the adjusting sleeve 22, ensuring that the adjusting sleeve 22 can only slide on the outer wall of the positioning rod 21 and will not rotate. This facilitates subsequent re-fixing of the adjusting sleeve 22 to the outer wall of the positioning rod 21 using the first limiting bolt 23. The same operation can then be used to change the position of the anti-vibration balance sleeve 31 on the outer wall of the positioning rod 21. Afterwards, the positioning rod 21 can be inserted into the inner wall of the lathe headstock 12, and the adjusting sleeve 22 can be threadedly connected to the lathe headstock 12. After fixing the positioning rod 21, its position is readjusted so that its end is in close contact with the end of the workpiece 15. Then, machining of the workpiece 15 can begin. When the workpiece 15 needs to be removed and reinstalled, simply press its end against the end of the positioning rod 21, and then clamp it with the three-jaw chuck 14. No further tool setting is required. In mass production, this device can quickly and efficiently control workpieces with equal lengths for each step, section, and end face, as the positioning rod 21 has already positioned one end face of the workpiece 15. Combined with the axial positioning of the machine tool... The electronic ruler of the machine tool or the ruler can easily control the length dimension, thereby realizing batch length positioning and precise control of the length of each section. It can be used in the actual processing of various round precision punches and punches. In summary, the workpiece 15 is self-centered and clamped by the three-jaw chuck 14, and then the end of the workpiece 15 is pressed by the positioning component 2, which facilitates subsequent processing. When the same workpiece 15 needs to be processed later, there is no need to perform tool setting again. In addition, the anti-vibration component 3 can ensure the stability of the positioning component 2 during the processing and prevent the positioning component 2 from shifting due to vibration during the processing.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
