Description
Technical field
The utility model belongs to chasing bar technical field, is specifically related to a kind of Manual tapping machine.
Background technology
Manually external threading is attacked conveniently in machine-building, occurred different types of Manual tapping machine on the market, current existing Manual tapping machine forms with feed mechanism (as shown in Figure 3, Figure 4) and screw tap vertically-guided mechanism (as shown in Figure 5, Figure 6) primarily of trade union college mechanism (as shown in Figure 1 and Figure 2), screw tap clamping.Its operation principle: workpiece is arranged on the platform of tapping machine by means of clamping accessory (parallel jaw or scroll chuck etc.), screw tap is fixed on column by clamping device, manually exert all one's strength and press down rotation hand wheel while spindle bar-linkage mechanism drives screw tap movement vertically downward, make screw tap vertically downward and rotate, shoot in the hole of workpiece, complete the processing of screwed hole.
The workbench of tapping machine shown in composition graphs 1, Fig. 2, wherein Figure 1 shows that common workbench, be with fluted, the accessory of the clamping workpiece such as parallel jaw or scroll chuck can be installed, but once clamping, then inconvenient shift position, is difficult to adjust the position (screw tap position) of workpiece relative to main shaft; Although workbench designed in Fig. 2 is with the device of unidirectional polymer product position, but must adjust by means of column simultaneously just can complete, and main shaft connecting rod is originally under multi-direction active force, easy distortion of long duration, affect screw tap perpendicularity, so it is not optimal structure that cooperating platform adjusts position.
The screw tap clamping of tapping machine shown in composition graphs 3, Fig. 4 and feed mechanism, wherein the screw tap clamping of tapping machine shown in Fig. 3 can make main shaft connecting rod drive screw tap to rotate with feed mechanism by rotary handle, lever handle drives main shaft connecting rod and the motion of screw tap bottom and top feed by moving up and down, but the power of the motion control main shaft of this lever is limited, and limit by stroke, control effects is general; In Fig. 4, rotary handle can drive screw tap to rotate, but main shaft connecting rod moves up and down and wants that armrest is dynamic to be made to defeat two ends handle and come, control is not steady, be difficult to control when making screw tap cut endoporus, and whole main shaft connecting rod and stressed etc. will to support by movable cantilever, service time is of a specified duration, is difficult to the perpendicularity ensureing main shaft connecting rod, i.e. the perpendicularity of screw tap.
