The quality problems of drilling on the box -like spare wall are solved to its purpose, can guarantee straightness accuracy, axiality and the size precision in hole on two walls through the drilling of these anchor clamps. The utility model discloses a basic part is the stand, hangs the support on the stand, installs the guide rail on the support, the guide rail a pair of bushing plate of making up, and the drill bushing is equipped with in bushing plate central authorities, and two clamp bolt pass the guide rail upper groove and are connected with the bushing plate, slide in the guide rail dovetail and adjust the position that clamp bolt adjusted the relative work piece of bushing plate through the bushing plate to guarantee the accuracy and drilling quality of drilling. The utility model discloses among the mainly used industrial production box -like part wall drilling, also can be used to the drilling of other parts.

Description

Box part boring grab

Technical field

This utility model relates to pincers worker boring grab, specifically a kind of box part boring grab。

Background technology

Box part is a kind of common part, hole thereon is usually blind hole (as shown in Figure 1) after front through hole, it is susceptible to crooked during boring, operation easier is big, especially the box part that pitch-row is longer is more difficult to ensure through hole, the linearity of blind hole, axiality and dimensional accuracy, and therefore pole needs a kind of fixture that can guarantee that drilling quality。

Summary of the invention

For adapting to the needs of box-shaped part boring in commercial production, improving production efficiency and drilling quality, this utility model provides a kind of energy to meet the boring grab of requirement。

The technical solution of the utility model is as follows: box part boring grab includes basic part, keeper and compressing member, described basic part is column, column suspended on bearing, bearing is installed keeper guide rail, being installed with a pair bushing plate on guide rail, described compressing member is hold-down bolt, and hold-down bolt is connected through the groove on guide rail with bushing plate, the central authorities of two bushing plates are equipped with drill bushing, and during work, drill bit implements drilling processing by drill bushing。

The beneficial effects of the utility model are as follows: 1, owing to being provided with a pair bushing plate with drill bushing, and drill bushing can be adjusted flexibly to suitable position by guide rail and hold-down bolt, it is possible to well ensure the accuracy of the axiality of boring, linearity, dimensional accuracy and position；2, simple in construction, low cost of manufacture；3, easy to operate, work efficiency is high, and operator's technical merit is less demanding。
