Problems solved by technology

This device can only process a single workpiece in sequence, and the tap needs to be separated from the tapered chuck to make the processed workpiece fall off. The production efficiency is still low. In addition, because the chuck clamps and fixes the workpiece, the position of the workpiece cannot be changed with the tap. The tension between the workpiece and the tap is high, and the wear is fast. The tapping products also have problems of large and small heads and partial buckles, which is not conducive to the processing of long-sized connecting sleeves.

Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the present invention is further described:

[0018] On the frame 1, the inner thread shaft sleeve 12 is fixedly installed, the mobile bracket 3 has a left side plate 17 and a right side plate 18, the left side plate 17 and the right side plate 18 are connected into one body through the bottom plate 19, and the active external thread shaft barrel 13 Through the internally threaded shaft sleeve 12, the two threads are engaged, and the two ends of the active externally threaded shaft sleeve 13 pass through the left side plate 17 and the right side plate 18 respectively. The situation shown in the drawings in this embodiment is the active externally threaded shaft One end of the sleeve 13 is fixed on the right side plate 18 via a bearing 20, the other end is fixed on the left side plate 17 with a bearing 22, and is fixedly connected with the first driving gear 21, and the tapping spindle 10 passes through the active external t...

Abstract

The invention discloses a two-way and double-station threading machine which comprises a stand; the stand is provided with a movable bracket; a thread tapping main shaft is driven to work left and right by the movable bracket so as to carry out alternate processing on two workpieces, so that the idle waiting time is shortened, and the production efficiency is increased; furthermore, the workpieces are matched with the movement of a screw tap, and the loss of the screw tap is less; the influence of human factors to the product quality is completely eliminated in the production, the problems of thread tapping concentric reducer and slanting buckling of the traditional device can be solved, and the thread tapping products are high in yield.

Description

technical field [0001] The invention relates to a tapping machine, in particular to a tapping machine capable of alternately tapping two workpieces in both left and right directions at the same time. Background technique [0002] In industries such as industry, agriculture, construction, and bridges, a large number of connecting sleeves are required. At present, vertical machine tools are mainly used for manual tapping of connecting sleeves. One person operates one machine tool, resulting in high labor costs, and taps are prone to appear during the tapping process. In the case of fracture, the production efficiency is low, and it is easy to cause problems of large and small heads and partial buckles in tapping products. This problem has long been troubled by the industry. Invention patent application 201210027571.5 discloses a tapping machine, including a machine tool, a gearbox, a rotating motor and a transmission. The guide rail of the machine tool is equipped with a reduc...
