Description

Technical Field

[0001] The utility model relates to the technical field of tapping machines, in particular to a tapping machine with a positioning and guiding function. Background Art

[0002] Tapping machines are mechanical devices used to cut threads on metal workpieces. They cut threads on the surface of the workpiece by rotating the tool or cutting head. Positioning guide is the tapping machine to accurately position the workpiece to the correct position, which can directly affect the quality and accuracy of the final thread.

[0003] In the prior art, a Chinese patent with authorization announcement number CN219852492U discloses a tapping machine with a positioning device, which belongs to the field of tapping machines. Its technical points include a workbench, a support frame is vertically arranged on the workbench, and also include: a tapping mechanism, which is movably connected to the support frame and is perpendicular to the workbench; a clamping mechanism, which is movably arranged on the tapping mechanism and is perpendicular to the workbench; a positioning mechanism, which is movably arranged on the workbench, and the positioning mechanism corresponds to the tapping mechanism and the clamping mechanism; the positioning mechanism is used to position the workpiece to be tapped, and the clamping mechanism is driven to descend when the tapping mechanism descends for tapping. While descending, the clamping mechanism preferentially contacts the workpiece to be tapped on the positioning mechanism, and while the tapping mechanism descends, it also drives one end of the positioning mechanism fixed on the tapping mechanism to descend, so that it gradually leaves the workpiece, and after the clamping mechanism clamps the workpiece, the tapping mechanism starts tapping, thereby ensuring the accuracy of tapping, facilitating operation, and improving its practicality.

[0004] At present, most tapping machines on the market still have certain shortcomings when in use. As shown in the above-mentioned document, when the tapping mechanism descends for tapping, the clamping mechanism drives the clamping mechanism to descend at the same time. While descending, the clamping mechanism preferentially contacts the workpiece to be tapped on the positioning mechanism to ensure the accuracy of tapping and facilitate operation. However, the device has many workpiece limiters and cannot adapt well to various types of workpieces. Moreover, the efficiency is not very high and there are certain shortcomings. Secondly, the device does not have a good shock-absorbing effect. The tapping screw processing process may vibrate, thereby accelerating material wear and affecting the service life. It is not very convenient to use. Utility Model Content
