Description

Technical Field

[0001] The utility model relates to the technical field of machining center tooling, in particular to a positioning tooling for a machining center. Background Art

[0002] Machining centers are mainly used to process and manufacture different types of workpieces. During the processing, fixtures are needed to position and fix the workpieces. They are mainly suitable for processing complex parts such as plates, discs, molds and small shells. Machining centers can complete processes such as milling, boring, drilling, tapping and cutting threads. When the workpiece is being processed, it needs to be clamped by tooling. However, the current positioning work can only be used to process the upper surface of the workpiece during processing. When the lower surface needs to be processed, it needs to be re-clamped, which is time-consuming and labor-intensive and inconvenient to use.

[0003] After searching, Chinese patent application No. 202122015284.X discloses an auxiliary positioning tool for a vertical machining center. This patent drives the main gear to rotate through a driving motor, and cooperates with the secondary gear to drive the rotating shaft to rotate synchronously, so that the positioning component can be automatically flipped. The bottom surface of the workpiece can be processed without secondary clamping. Although the above patent has the function of automatic flipping, it is inconvenient to process the workpiece in the clamping and positioning part. After the positioning tool clamps the workpiece, the clamping structure will be close to the surface of the workpiece, causing this part of the workpiece to be blocked. If processes such as scraping burrs are required, the workpiece needs to be disassembled and reassembled, and the current positioning tool does not have the function of clamping special-shaped workpieces. Therefore, it is necessary to design a positioning tool for a machining center. Utility Model Content

[0025] During specific use, first place the workpiece body 17 between the two groups of clamping plates 5, and move the clamping plates 5 closer to each other by rotating the bidirectional screw rod 2. After continuing to rotate, the workpiece body 17 is clamped inside the groove 6, and the roller 7 is pressed against the workpiece to produce a clamping effect. After the workpiece is fixed, it is processed. When the clamping part of the workpiece needs to be processed, it is only necessary to rotate the two adjacent groups of rollers 7 at the same time through the handle 8, and use the other two groups of rollers 7 to have a rotating effect, so that the workpiece body 17 can be subjected to the force to move horizontally, and clamp the workpiece at different positions. At this time, the exposed parts can be scraped for burrs and other operations.

After continuing to rotate, the workpiece body 17 is clamped inside the groove 6, and the roller 7 is pressed against the workpiece to produce a clamping effect. After the workpiece is fixed, it is processed. When the clamping part of the workpiece needs to be processed, it is only necessary to rotate the two adjacent groups of rollers 7 at the same time through the handle 8. The other two groups of rollers 7 have a rotating effect, so that the workpiece body 17 can be subjected to the force to move horizontally, and the workpiece can be clamped at different positions. After rotation, the limit rod 9 is inserted into the corresponding positioning hole 16 to facilitate the handle 8 to produce The limit is used to prevent the rotation of the roller 7 from affecting the processing. At this time, the exposed parts can be scraped for burrs and other operations to avoid the trouble of frequent disassembly of the workpiece. When it is necessary to clamp the special-shaped or curved workpiece, the worm 15 can be driven to rotate by rotating the rotating shaft 14. The meshing effect of the worm 15 and the worm wheel 13 is used to make the worm 15 drive the worm wheel 13 to rotate. The transmission rod 4 rotates after receiving the force of the worm wheel 13. At this time, the splint 5 produces a flipping effect. The appropriate angle is adjusted according to the size of the workpiece. The one-way transmission of the worm 15 is used to fix it by loosening it, and then the two-way screw 2 is rotated to enable the splint 5 to clamp the special-shaped workpiece, thereby increasing the processing range.
