Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to a tooling fixture for numerically controlled lathes. Background Art

[0002] CNC lathe is an automated machine tool controlled by a computer. Compared with traditional lathes, CNC lathes have a higher degree of automation and precision. CNC lathes control the processing of workpieces on the lathe through pre-programmed instructions. When CNC lathes process workpieces, they usually need to be clamped to maintain the stability of the workpiece during processing.

[0003] For example, the Chinese utility model patent with the announcement number "CN220295859U" discloses "a clamp for a CNC lathe, including an operating table, an inner slide groove is provided inside the operating table, drainage grooves are provided downward on both sides of the inner slide groove, a water receiving box is provided inside the operating table, a guide frame is fixedly connected to the middle position of the bottom plate of the inner slide groove, and the inner walls on both sides of the inner slide groove are fixedly connected to limit plates. The clamp for the CNC lathe reselects the corresponding inner slide groove according to the size of the workpiece, and then the main clamp and the auxiliary clamp are respectively inserted into the inner slide groove from both sides of the inner slide groove, and then the workpiece is placed on the top of four groups of support platforms, and the four groups of screws are rotated to clamp the workpiece inside the main clamp and the auxiliary clamp, and then the bolt and nut groups on the top of the two groups of support plates are rotated to fix the two groups of main clamps, so that the entire workpiece is fixed below the top plate processing tool, thereby improving the convenience of adjusting the clamping size of the device."

[0004] With respect to the above-mentioned related technologies, when clamping a workpiece, after the main clamp is moved to a suitable position, it is necessary to screw multiple bolt and nut groups on the outside of the support plate to fix it, which is quite troublesome. Secondly, after the position of the main clamp is fixed, when clamping the workpiece, it is also necessary to screw multiple rotating screws to drive the pressing plate to move down before the workpiece can be clamped, which makes the clamping and fixing steps of the workpiece quite cumbersome, greatly reducing the processing efficiency of the workpiece. Therefore, those skilled in the art provide a tooling fixture for a CNC lathe to solve the problems raised in the above-mentioned background technology.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

Figure 1-3 A fixture for a numerically controlled lathe comprises an operating table 1, a groove 2 and a plurality of slide grooves 3 are provided on the operating table 1, the slide groove 3 is connected with the groove 2, and an electromagnet 4 is provided in the groove 2, a plurality of support plates 5 are provided at the upper end of the operating table 1, a U-shaped plate 6 is provided at the upper end of the support plate 5, and a positioning mechanism 7 for limiting and fixing the support plate 5 is provided at the upper end of the support plate 5, and a fixing mechanism 8 is provided on the U-shaped plate 6 for clamping and fixing the workpiece;

[0031] Reference Figure 3 The positioning mechanism 7 includes a T-shaped rod 701, a magnetic block 702 and a first spring 703. The T-shaped rod 701 is inserted on the support plate 5. The bottom end of the T-shaped rod 701 passes through the slide groove 3 and is inserted into the groove 2. The magnetic block 702 is arranged at the bottom end of the T-shaped rod 701, and the magnetic block 702 is magnetically adsorbed with the electromagnet 4 to limit and fix the support plate 5. The first spring 703 is sleeved on the outside of the T-shaped rod 701, and the two ends of the first spring 703 are respectively connected to the T-shaped rod 701 and the support plate 5.

[0032] By adopting the above technical solution, after the support plate 5 moves to a suitable position, the electromagnet 4 can work to make the magnetic block 702 move down and be magnetically adsorbed by the electromagnet 4, so that the support plate 5 can be limited and fixed, and the operation is simpler and more convenient.

[0033] Reference Figure 3 The fixing mechanism 8 includes a vertical rod 801, a fixing plate 802, a pull rod 803 and a second spring 804. The vertical rod 801 is arranged on the inner side of the U-shaped plate 6. The bottom end of the vertical rod 801 is connected to the upper end of the support plate 5. The fixing plate 802 is slidably arranged on the vertical rod 801. The bottom end of the vertical rod 801 contacts the upper end of the support plate 5. The pull rod 803 is arranged at the upper end of the fixing plate 802 for pulling the fixing plate 802 to move upward. The second spring 804 is sleeved on the outer side of the vertical rod 801. The two ends of the second spring 804 are respectively connected to the U-shaped plate 6 and the fixing plate 802.

[0034] By adopting the above technical solution, when the fixed plate 802 contacts the workpiece, the pull rod 803 is pulled to move the fixed plate 802 upward, and then the support plate 5 is continued to be moved so that the U-shaped plate 6 contacts the outer side of the workpiece. At this time, the pull rod 803 is released, and the elastic force of the second spring 804 can drive the fixed plate 802 to move downward to squeeze the workpiece, so that the outer side and the upper end surface of the workpiece can be clamped, making the clamping of the workpiece more stable.

[0035] Reference Figure 1 and Figure 2 A placement plate 9 is provided in the middle of the upper end of the operating table 1, which is at the same horizontal height as the supporting plate 5 and is used for placing the workpiece.

When processing a workpiece, the workpiece is placed on the placement plate 9, and then one of the T-shaped rods 701 is inserted into a suitable slide groove 3 according to the size of the workpiece, and the U-shaped plate 6 is pushed to move toward the workpiece. When the fixed plate 802 contacts the workpiece, the pull rod 803 is pulled to move the fixed plate 802 upward, and then the support plate 5 is continued to be moved to make the U-shaped plate 6 contact the outer side of the workpiece. At this time, the pull rod 803 is released, and the second spring 8 The elastic force of 04 can drive the fixed plate 802 to move down to squeeze the workpiece, and then the remaining three T-shaped rods 701 are also inserted into the slide groove 3 in this way, and the fixed plate 802 also squeezes the workpiece, and then the electromagnet 4 works to make the magnetic block 702 move down and magnetically adsorb with the electromagnet 4, so that the support plate 5 can be limited and fixed, so that the outer side and the upper end surface of the workpiece can be clamped, so that the workpiece can be processed more stably, and the whole operation process is simpler, which greatly improves the processing efficiency of the workpiece.

[0040] When the utility model is used, the operation process of clamping the workpiece is simpler and more convenient, so that the processing efficiency of the workpiece is greatly improved.
