Abstract

The utility model discloses a fixture for boring of large beams. The fixture comprises a base, an L-shaped support arm is hinged on the base in a rotating mode, a screw is matched with the support arm in a spiral mode, a handle is installed at the top of the screw, a press disk is arranged at the lower end of the screw, and a corbel is placed on the base. According to the fixture, the support arm hinged on the base is adopted to press at the upper ends of workpieces for clamping and fixing, the fixture is convenient and rapid in assembly and stable and accurate in clamping, the accuracy and the efficiency of boring are guaranteed, and boring quality of the large beams is improved.

Description

A kind of bore hole of large-scale beam is used anchor clamps
Technical field
The utility model relates to bore hole and uses anchor clamps, and the bore hole that specifically belongs to a kind of large-scale beam is used anchor clamps.
Background technology
Large-scale beam adds man-hour at bore hole; Because size and weight are bigger, bore hole adds trade union and insufficient clamping force occurs, locatees inaccurate phenomenon; And after the specifications vary; Need design new anchor clamps again again, bring a lot of wastes and cost, therefore must design the anchor clamps that a kind of large-scale beam bore hole that can satisfy plurality of specifications is used to production.
The utility model content
The purpose of the utility model provides a kind of bore hole of large-scale beam and uses anchor clamps, and is easy to assembly quick, clamps and stablizes accurately, guaranteed the accuracy and the efficient of bore hole, improved the bore hole quality of large-scale beam.
The technical scheme of the utility model is following:
A kind of bore hole of large-scale beam is used anchor clamps, includes base, is rotatablely hinged with L shaped support arm on the base, and screw fit has screw rod on the support arm, and the top of screw rod is equipped with handle, and the lower end of screw rod has platen, is placed with sleeper beam on the base.
Be equipped with briquetting between described platen and the large-scale beam workpiece.
The upper end that the utility model adopts the support arm that is articulated on the base to be pressed on workpiece is fixedly clamped, and is easy to assembly quick, clamps and stablizes accurately, guaranteed the accuracy and the efficient of bore hole, improved the bore hole quality of large-scale beam.
Description of drawings
Fig. 1 is the structural representation of the utility model.
