The lower nut can be rotated to move the upper clamp back to the bottom of the connecting block for support. At the same time, the movement of the upper clamp causes the extension block to slide into the adjusting groove. If the small-diameter clamp is installed on the upper clamp, it will move upward synchronously to quickly clamp the workpiece. The clamp can be adjusted as needed to adapt to workpieces of different sizes. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 , Figure 4 , Figure 5 An embodiment of this utility model provides a clamp lathe machining fixture, including a base 1. Support modules 2 are fixedly connected to the upper left and right sides of the base 1. An installation groove 3 is opened on the upper side of the base 1. A lower clamp 4 is engaged and connected inside the installation groove 3. An upper clamp 6 is attached to the upper part of the lower clamp 4. Sliding grooves 25 are opened on the front and rear sides of the installation groove 3. A conical block 18 is slidably connected to the side of the sliding groove 25 that is close to each other. A telescopic rod 19 is fixedly connected to the side of the conical block 18 that is far away from each other. A connecting block 21 is fixedly connected to the end of the telescopic rod 19 that is far away from each other. A through groove 22 is opened inside the side of the connecting block 21 that is far away from each other. A positioning component is fixedly connected inside the through groove 22. The positioning component is used to firmly install the lower clamp 4 inside the installation groove 3. A spring 20 is sleeved on the outside of the telescopic rod 19.
[0032] The positioning component includes a telescopic member 23, which is fixedly connected to the bottom inside of the through groove 22. A locking block 24 is fixedly connected to the upper end of the telescopic member 23. A slot 26 is opened on the upper part of the sliding groove 25 on the side away from the groove. The locking block 24 is slidably connected inside the slot 26. The bottom of the slot 26 on the side closer to the groove is inclined. The two ends of the second spring 20 are fixedly connected to the inner wall of the sliding groove 25. The middle part of the sliding groove 25 is cylindrical, and the diameter of the openings at both ends of the cylinder is smaller than the diameter of the second spring 20.
[0033] When the clamp model does not match the workpiece or requires regular maintenance, the upper nut 11 is rotated to separate from the adjusting screw 10. Then, the handle 9 is pulled upward to separate the upper clamp 6 from the adjusting screw 10. Subsequently, the lower clamp 4 is pulled upward, causing the conical block 18 to be squeezed and moved out of the lower clamp 4. This squeezes the telescopic rod 19 and the second spring 20, generating a rebound force. After the lower clamp 4 is moved out of the mounting groove 3, the rebound force of the telescopic rod 19 and the second spring 20 drives the second connecting block 21, causing the clamp block 24 to be squeezed by the edge of the groove 26 and enter the through groove 22 to squeeze the telescopic component 23. This allows the positioning structure to slide as a whole in the sliding groove 25, enabling convenient disassembly of the clamp to adjust or maintain its state, ensuring its normal operation and adaptability to different workpiece requirements.
[0034] Reference Figures 1-3 The lower clamp 4 has an adjustment groove 5 on the side closer to the upper clamp 6. The bottom of the upper clamp 6 is fixedly connected to an extension block 7, which is slidably connected inside the adjustment groove 5. Both sides of the upper clamp 6 are fixedly connected to connecting blocks 8. The side of the connecting blocks 8 closer to each other is slidably connected to an adjustment screw 10. The bottom end of the adjustment screw 10 is fixedly connected to the upper part of the support module 2. Small diameter clamps 12 are installed on the front and rear sides of the upper clamp 6 and the lower clamp 4. Both sides of the small diameter clamps 12 are fixedly connected to mounting blocks 13. The mounting blocks 13 are fixedly connected to the upper clamp 6 by bolts 14. A handle 9 is fixedly connected to the upper part of the side of the connecting block 8 away from each other. Nuts 11 are threadedly connected to the upper outer side of the adjustment screw 10 and the lower side of the connecting block 8.
[0035] Hydraulic rods 15 are fixedly connected to the left and right sides of the inner walls of the lower clamp 4, upper clamp 6 and small diameter clamp 12. An arc-shaped block 17 is fixedly connected to the output end of the hydraulic rod 15. A spring 16 is sleeved on the outside of the hydraulic rod 15. One end of the spring 16 is fixedly connected to the bottom of the arc-shaped block 17, and the other end of the spring 16 is fixedly connected to the inner walls of the lower clamp 4, upper clamp 6 and small diameter clamp 12.
[0036] By inserting the workpiece to be processed into the clamp, and under the action of the hydraulic rod 15 and the spring 16, the arc-shaped block 17 is brought into contact with the workpiece and firmly clamped. When the size of the workpiece changes, the small diameter clamp 12 can be removed or installed in front of and behind the lower clamp 4 and the upper clamp 6, or the handle 9 can be pulled upwards to make the upper clamp 6 slide outside the adjusting screw 10 under the drive of the connecting block 8. Then the nut 11 on the lower side is rotated to move it back to the bottom of the connecting block 8 to support the upper clamp 6. At the same time as the upper clamp 6 moves, the extension block 7 is driven to slide in the adjusting groove 5. When the small diameter clamp 12 is installed on the upper clamp 6, the small diameter clamp 12 is moved upwards synchronously, realizing the rapid clamping of the workpiece and the adjustment of the clamp as needed to adapt to workpieces of different sizes, ensuring the stability and safety of clamping, which not only improves the processing efficiency, but also enhances the versatility and flexibility of the equipment.
[0037] Working principle: When this fixture is needed, the workpiece is inserted into the clamp, and the arc-shaped block 17 is brought into contact with and clamped to the workpiece by the action of the hydraulic rod 15 and the spring 16. When the workpiece size changes, the small diameter clamp 12 can be removed or reinstalled in the front or rear position of the upper and lower clamps 4 and the upper clamp 6. Alternatively, the handle 9 can be pulled upward to make the upper clamp 6 slide to the outside of the adjusting screw 10 under the action of the connecting block 8, and the lower nut 11 can be rotated to move the upper clamp 6 back to the bottom of the connecting block 8 for support. At the same time, the movement of the upper clamp 6 causes the extension block 7 to slide into the adjusting groove 5. If the small diameter clamp 12 is installed on the upper clamp 6, it will move upward synchronously to quickly clamp the workpiece. The clamps can be adjusted as needed to adapt to different sizes. For workpieces of different sizes; when the clamp model does not match the workpiece or requires regular maintenance, the upper nut 11 is rotated to separate it from the adjusting screw 10, and then the handle 9 is pulled upward to separate the upper clamp 6 from the adjusting screw 10. Then the lower clamp 4 is pulled upward, causing the conical block 18 to be squeezed and moved out of the lower clamp 4, and applying pressure to the telescopic rod 19 and the second spring 20 to generate a rebound force. After the lower clamp 4 is moved out of the mounting groove 3, under the action of the rebound force of the telescopic rod 19 and the second spring 20, the connecting block 21 is moved, causing the clamp block 24 to be squeezed by the edge of the groove 26 and enter the through groove 22, and applying pressure to the telescopic component 23, so that the positioning structure slides in the slide groove 25, thereby realizing the convenient disassembly or maintenance of the clamp.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
