Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of screw tap apparatus for correcting, particularly a kind of screw tap vertical correction device.
Background technology
In machining, a lot of machine shop automaticity is not very high at present, and fixture, cubing, frock are being carried out to the common screw tap of many uses in screw tap trial-manufacturing process and carried out manual screw tap.Existing manual thread-cutting tool is confined to the Simple spanner of type T-shape, and in screw tap process, both hands are held two and carried out screw tap, and owing to cannot fix the direction of screw tap, in its process, stability is bad, unbalance stress.Make some complex structures, required precision workpiece accurately, the phenomenon such as usually occur screw mandrel out of plumb when artificial screw tap, silk hole is departed from.Cooperation is not easily installed in the silk hole of deflection, and once attacks screw tap forced breakage partially can be caused to cause tool loss.
The screw tap mechanism improving perpendicularity precision is have developed for above-mentioned shortcoming people:
As Chinese patent application (application number: 201310272220.5) a kind of manual screw tap mechanism, comprises screw tap, screw tap comprise cone bar and be arranged on cone bar upper end handle, wherein, also comprise be arranged on cone bar on directed folding frame and two workpiece geometrical clamps.Located by fixing folding frame and workpiece geometrical clamp, thus ensure perpendicularity.
Although above-mentioned this manual screw tap mechanism to some extent solves the shortcoming existed in internal thread machining, ensure that certain perpendicularity, but still there is following defect: 1, the installation of fixing folding frame and geometrical clamp makes the position of machining hole have limitation, be difficult to processing from the hole away from the edge of work, poor universality.2, owing to easily there is error in folding frame and geometrical clamp installation processing, processing effect is not good, bores bar simultaneously and is located in directional hole, because the existence in gap still deflection can occur in process, is difficult to ensure absolute perpendicularity.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, and propose a kind of screw tap vertical correction device, technical problem to be solved in the utility model is: the rectification how realizing screw tap perpendicularity, ensures the precision of processing.
The purpose of this utility model realizes by following technical proposal: a kind of screw tap vertical correction device, it is characterized in that, comprise support, push rod and the screw tap for screw tap, described screw tap is detachably connected on the end of push rod, described support has the butting section that can be resisted against on workpiece, described support offers screwed hole, described push rod to be located in screwed hole and to be connected by threaded engagement with support, described butting section offers resigning hole, described resigning hole and the screwed hole concentric that can pass for described screw tap.
Determine the size of machining hole in screw tap process after, determine the screw tap size for screw tap on push rod, screw tap is arranged on push rod.Utilize and support can be resisted against butting section on workpiece and surface engagement to be processed positions, by the active force perpendicular to workpiece produced in the contact of butting section and surface of the work and process, butting section and surface of the work are fitted tightly more.The contact in face and face limits the free degree in process, not easily the phenomenons such as riding occurs, can ensure the perpendicularity in process.The screwed hole that push rod and support are offered carries out screw-driven by threaded engagement, make screw tap pass the resigning hole concentric with screwed hole at the uniform velocity forward and back screw tap is carried out to workpiece.Screw-driven makes screw tap maintenance perpendicular to the direction of feed of workpiece, improves the perpendicularity in silk hole further.
