[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. The present invention is provided with a processing table, an adjustment mounting table, a movable mounting block, a tool rod and a mounting tool head. A supporting electric push rod is installed in the center of the processing table, and the output end of the supporting electric push rod is connected to the adjusting mounting table. A plurality of first guide slide bars are evenly and fixedly installed on the bottom surface of the adjusting mounting table, and the first guide slide bars are sleeved in the first guide slide sleeve fixedly installed on the processing table. A lathe headstock is fixedly installed on the top surface of the adjusting mounting table, and a Morse taper handle is connected to the output end of the lathe headstock, and a dividing plate is installed on the Morse taper handle. A three-jaw chuck is fixedly installed on the dividing plate, which can be used to clamp and fix one end of a workpiece to be processed. On the other hand, connecting frames are welded at the four corners of the top surface of the processing table, and a top plate is welded on the top of the connecting frame. A guide slot is provided in the center of the bottom surface of the top plate, and a driving screw is installed in the guide slot, and one end of the driving screw is connected to the output end of the servo motor, a guide slider is embedded in the guide slot, and a screw sleeve is fixedly installed in the guide slider, and the screw sleeve cooperates with the driving screw, a mobile mounting block is fixedly installed at the bottom end of the guide slider, and a mounting slot is symmetrically provided on the bottom surface of the mobile mounting block, mounting pins are welded on the set tool rods, and fixing screw holes are correspondingly provided on the mounting pins and the mounting slots. During installation, the mounting pins can be correspondingly embedded in the mounting slots, and then the fixing bolts can be screwed into the fixing screw holes, so that the tool rod can be fixedly installed on the mobile mounting block, one end of the set tool rod is provided with a mounting threaded groove, and one end of the mounting head is fixedly provided with a mounting screw. A mounting thread head is provided, which can be screwed and installed in the mounting thread groove, so that the mounting tool head is installed on the tool rod, a first turning tool seat is fixedly installed on the set mounting tool head, and a roughing thread turning tool is installed in the first turning tool seat, a second turning tool seat is fixedly installed on the set mounting tool head, and a finishing thread turning tool is installed in the second turning tool seat. As mentioned above, when in use, the worker can fix one end of the workpiece to be processed on the three-jaw chuck. If trapezoidal thread turning is performed on the outer surface of the workpiece, the servo motor can be started to drive the driving screw to rotate, so that the movable mounting block drives the tool rod and the mounting tool head to move along the direction of the guide slide groove, so that the roughing thread turning tool and the finishing spiral turning tool are both moved to just above one end of the outer surface of the workpiece. At this time Workers can use the control panel to control the start-up support electric push rod to push the adjustment mounting table up along the first guide slide bar according to parameters such as the diameter of the workpiece to be processed and the depth of trapezoidal thread processing. When the outer surface of the workpiece contacts the roughing thread turning tool and the fine-machining spiral turning tool, the lathe headstock is started at the same time to drive the workpiece to be processed to rotate, and the servo motor drives the mobile mounting block together with the roughing thread turning tool and the fine-machining spiral turning tool to push along the guide slide groove. At this time, the roughing thread turning tool and the fine-machining spiral turning tool can turn the thread line on the surface of the workpiece. The tool setting of the roughing thread turning tool is mainly to remove the excess along the spiral line direction, while the tool setting of the fine-machining thread turning tool is mainly to ensure the thread tooth shape and size. Two turning tools are used to process a trapezoidal thread groove.Thus, the trapezoidal thread turning processing of workpieces of various specifications and diameters can be realized. The supporting electric push rod can be used for automatic calibration through the workpiece data parameters and the processing parameters required, without the need for manual operation and adjustment by workers. It is not only more convenient to use, but also has higher processing accuracy, ensuring the processing quality of the product. In addition, when it is necessary to process the trapezoidal thread on the inner surface of the workpiece, according to the above principle, the center axis of the clamped workpiece to be processed can be aligned with the center axis of the mounting cutter head and the tool rod, and then the mounting cutter head can be pushed into the inner cavity of the workpiece to be processed by using the mobile mounting block, and then the roughing thread turning tool and the finishing spiral turning tool can be brought into contact with the inner wall of the workpiece according to the workpiece parameters and the processing parameters. Similarly, the trapezoidal thread turning processing is performed, so that the processing application range of a trapezoidal thread processing device is wider and more practical.

[0026] 2.

As described above, when one end of the workpiece to be processed is fixedly installed on the three-jaw chuck When the workpiece is turned, the worker can rotate the two adjusting threaded rod shafts. Because the second guide slide bar fixedly installed on the bottom surface of the mounting seat is sleeved in the cross slide block and the second guide slide sleeve fixedly installed on the adjusting mounting table, the mounting seat and the arc-shaped support block can be driven to rise along the direction of the second guide slide bar as the adjusting threaded rod shaft rotates until the rolling steel ball abuts against the bottom surface of the workpiece to be processed. The set mounting seat and arc-shaped support block can be used to support the workpiece to be processed to prevent the workpiece from jumping and deviating during the turning process and affecting the processing accuracy. The set rolling steel ball ensures that the arc-shaped support block will not affect the rotation of the workpiece. The adjusting electric push rod can drive the mounting seat and the arc-shaped support block on one side to move to meet the needs of supporting both ends of the bottom surface of the workpiece to be processed of different lengths, and will not affect the turning of the trapezoidal thread line, which is more practical.

[0027] 3. The present invention is provided with a cutting fluid box, a tool rod, a mounting tool head and a filter box.

On the thread turning tool, in order to protect the turning tool and improve the turning quality at the same time, the processing table is symmetrically provided with liquid guide grooves. The flowing turning fluid can fall into the inner cavity of the filter box installed on the support frame under the guidance of the liquid guide grooves. The inner walls of the two filter boxes are fixedly installed with placement seats, and filter screen plates are placed on the placement seats. The filter screen plates can intercept and filter metal debris in the cutting fluid. A connecting pipe is installed between the two filter boxes, and a reflux pipe is installed between the bottom of the inner cavity of the filter box on one side and the inner cavity of the cutting fluid box. Therefore, the cutting fluid that has been filtered and impurities removed can flow back to the inner cavity of the cutting fluid box for recycling, so as to reduce the waste of cutting fluid and save resources.
