Abstract

A simple tapping device with a relatively small space is formed by a threaded hole plate and bolts. The simple tapping device with the relatively small space clamps a screw tap through match of threaded holes evenly formed all around the simple tapping device with the relatively small space and the bolts, and adjusts clamping centring degree and claming force through the bolts around the simple tapping device with the relatively small space. After adjustment, the screw tap is vertically placed on a bottom hole, and tapping can be carried out to a work piece or paint painted in the tapped threaded holes and impurities are removed from the tapped threaded holes, and thread forms of the tapped threaded holes are corrected.

Description

The simple and easy chasing bar of space less

Technical field

The utility model relates to the workpiece that the complete bottom outlet of general brill needs tapping, especially needs to correct the parts of tooth form after the assembling, is specially adapted to the parts of space less.

Background technology

No matter be a machine or a kind of engineering goods, they all are to have a plurality of parts to combine.Inevitably used screw tap in parts machining and assembling process, chasing bar commonly used has special-purpose instrument.But this instrument may cannot use in the scope of space less sometimes, and this specific purpose tool cost is also relatively high.

Summary of the invention

The utility model provides the simple and easy chasing bar of space less.

The purpose of this utility model is achieved in that by the screwed hole size of workpiece needs selects bottom outlet drill bit and screw tap size, after bottom outlet is good with bit drills, screw tap is placed on the screw thread orifice plate center of chasing bar, adjust centering degree and the clamping dynamics of screw tap by the bolt at four sides, after the adjustment screw tap vertically is placed on the bottom outlet, just can carries out tapping or the screwed hole of attacking silk rolling be removed paint, impurity and the rectification tooth form of the inside spraying workpiece.

The simple and easy chasing bar of this space less is comprised of screw thread orifice plate, bolt.The simple and easy chasing bar of this space less cooperates to clamp screw tap by the uniform screwed hole in four sides with bolt, and adjusts centering degree and the clamping dynamics of clamping by the bolt at four sides.

This device of the beneficial effects of the utility model solved well because of narrow space can't tapping, correct the problem of tooth form and reduced cost of use, saved resource, a kind of new chasing bar is provided simultaneously, be convenient to screwed hole tapping, remove the impurity be attached on the tooth form and the rectification of tooth form.

The specific embodiment

Bolt 2 is assemblied on the screw thread orifice plate 1, screw tap 3 is placed in the hole of screw thread orifice plate 1 centre, regulate centering degree and the clamping dynamics of screw tap 3 and screw thread orifice plate 1 by adjusting bolt 2, the shank of bolt of pulling the four sides after the adjustment comes the hole on the parts is carried out tapping or corrected tooth form.By above installation, finish present embodiment.

Claims

1. the simple and easy chasing bar of space less, it is characterized in that: the simple and easy chasing bar of this space less is comprised of screw thread orifice plate, bolt, the simple and easy chasing bar of this space less cooperates to clamp screw tap by the uniform screwed hole in four sides with bolt, and adjusts centering degree and the clamping dynamics of clamping by the bolt at four sides.
