Abstract

The utility model discloses a boring clamp, comprising a fixed base, wherein a U-shaped bracket is fixedly arranged on the fixed base, the U-shaped bracket is fixedly connected with a triangle upper-frame, an annular surface is surrounded by the U-shaped bracket and the triangle upper-frame, two sides of the U-shaped bracket and the middle part of the triangle upper-frame are respectively provided with a clamping claw in the annular surface, the three clamping claws are distributed in a regular triangle in the annular surface, one end of each of the clamping claws is in threaded connection with an adjusting nut, and the other end of each of the clamping claws is connected with a bearing which can rotate around the end part of the clamping claw. Through the adjustment of positions of the clamping claws, the boring clamp clamps a processing workpiece through the clamping claws distributed in a regular triangle, the clamped processing workpiece is processed in a rotating manner through the bearings which can rotate freely, and the boring clamp has the advantages of fast clamping speed, convenient adjustment, and large adjustment degree of the clamping claws, so that the workpiece clamping ranged of the whole clamp is wide.

Description

A kind of boring jig
Technical field
The utility model relates to fixture field, relates in particular to a kind of boring jig of large-scale workpiece.
Background technology
In field of machining, various workpiece, especially large-scale workpiece all need clamp to process adding man-hour, and fixture is used for fixing processing object in machine-building process, makes it to occupy correct position, to accept construction or to detect.The boring jig gripping speed of tradition large-scale workpiece is slow, and is difficult for regulating, and adjustment degree is low, and the scope of application is little.
Utility model content
For solving the problems of the technologies described above, the utility model has designed a kind of boring jig of large-scale workpiece.
The utility model adopts following technical scheme:
A kind of boring jig, comprise firm banking, on firm banking, be fixedly installed U-shaped support, on U-shaped support, be fixedly connected with triangle upper frame, U-shaped support and triangle upper frame surround an anchor ring, and in anchor ring, U-shaped support both sides and triangle upper frame middle part are respectively arranged with claw, and three claws are positioned at anchor ring and are positive angular distribution, claw threaded one end is connected with adjusting nut, and the claw other end is connected with the bearing that can rotate around claw end.This boring jig is adjusted the position of claw by adjusting nut, by being the claw of positive angular distribution, close up to come gripping processing work, the processing work of gripping rotates processing by bearing free to rotate, this boring jig gripping speed is fast, easy to adjust, the regulating degree of claw is large, thereby makes the scope of whole fixture gripping workpiece wide.
As preferably, in described anchor ring, in U-shaped support both sides and triangle upper frame, the claw junction of part is provided with clamping screw.By locking nut, can after adjusting completes, lock claw, prevent that claw is loosening.
As preferably, described U-shaped support and triangle upper frame are bolted to connection.
The beneficial effects of the utility model are: this boring jig gripping speed is fast, easy to adjust, and regulating degree is large, and the scope of gripping processing work is wide.
Accompanying drawing explanation
A kind of structural representation when Fig. 1 is the utility model gripping workpiece;
In figure: 1, firm banking, 2, U-shaped support, 3, triangle upper frame, 4, processing work, 5, claw, 6, bearing, 7, clamping screw, 8, adjusting nut.
The specific embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described specifically:
Embodiment: as shown in Figure 1, a kind of boring jig, comprise firm banking 1, on firm banking, be fixedly installed U-shaped support 2, on U-shaped support, be fixedly connected with triangle upper frame 3, U-shaped support and triangle upper frame surround an anchor ring, in anchor ring, U-shaped support both sides and triangle upper frame middle part are respectively arranged with claw 5, three claws are positioned at anchor ring and are positive angular distribution, claw threaded one end is connected with adjusting nut 8, the claw other end is connected with the bearing 6 that can rotate around claw end, in anchor ring, in U-shaped support both sides and triangle upper frame, the claw junction of part is provided with clamping screw 7, U-shaped support and triangle upper frame are bolted to connection.
This boring jig is adjusted the position of claw by adjusting nut, by being the claw of positive angular distribution, close up to come gripping processing work 4, the processing work of gripping rotates processing by bearing free to rotate, this boring jig gripping speed is fast, easy to adjust, the regulating degree of claw is large, thereby makes the scope of whole fixture gripping workpiece wide.
Above-described embodiment is a kind of preferably scheme of the present utility model, not the utility model is done to any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim records.
