Abstract
Disclosed is a large-diameter bend flame cutter fixture. A spindle below a bend support frame is driven to rotate by an actuating unit of the large-diameter bend flame cutter fixture, the bend support frame and a large-diameter bend in the bend support frame are driven to rotate by the spindle, and the frame cutting torch is fixed. According to above structure, the frame cutting torch for processing the large-diameter bend is fixed, so that end faces of the large-diameter bend can be processed smoothly when the fixture is turned to the large-diameter bend.
Description
Technical field
The present invention relates to a kind of clamping tool for machine work, especially relate to a kind of clamping tool for machine work of flame cutting large caliber bend.
Background technology
At present, external diameter is carried out machining greater than the port of the large caliber bend of 1.2m,, need on milling-boring machine, carry out owing to receive the processing conditions and the high-precision requirement of elbow end face groove of lathe self.Because the appearance profile of elbow is a circular arc, the clamping location of elbow is difficulty relatively.And the output investment ratio of this elbow cutting equipment is bigger; And usage ratio of equipment is lower; Chinese patent 200920218022.X discloses a kind of elbow groove anchor clamps, and these elbow groove anchor clamps comprise beveling machine base (1), and one group of dovetail mount (2) is installed on the described beveling machine base (1); Dovetail mount (2) is inboard to be fixed with one group of fixed head (4) through fastening bolt (3), and it is " V " font jig A (5) and " V " font jig B (6) that fixed head (4) inboard is fixed with inner surface respectively through bolt.Be elbow to be stuck on " V " font jig A (5) and " V " font jig B (6) during use." V " font jig that this kind anchor clamps use still is difficult to effective clamping for elbow, and is prone to cause workpiece to damage, mounting or dismounting inconvenience.It is thus clear that, because the appearance profile of elbow is a circular arc, the clamping location difficulty of elbow; Particularly for large caliber bend, because elbow appearance and size is bigger, and the dimensioned precision of elbow is high; According to traditional machining clamping method; Elbow end face after the machine-shaping is difficult to guarantee smooth, and machining angle is difficult to meet the demands, and does not all reach more satisfactory result.
Summary of the invention
Be difficult to make the processed smooth deficiency of elbow end face in order to overcome existing large caliber bend cutting clamper; The utility model provides a kind of large caliber bend flame cutting clamper; This large caliber bend flame cutting clamper adopts flame cutting torch to fix and mode that anchor clamps rotate is cut; Simple in structure, easy to make, can reach the processed smooth required precision of elbow end face.
The utility model solves the technical scheme that its technical problem adopted: a kind of large caliber bend flame cutting clamper comprises workbench, elbow bracing frame, locating piece; The elbow bracing frame links to each other with locating piece; One end of locating piece is an arc-shaped curved surface; The elbow bracing frame also links to each other with main shaft, and main shaft links to each other with an actuating unit, and the lower end of main shaft links to each other with workbench through bearing.
A kind of prioritization scheme of such scheme is: above-mentioned actuating unit is a reducing motor, and the arbor of reducing motor links to each other with gear on being fixed on main shaft through chain.
The another kind of prioritization scheme of such scheme is: the flame cutting torch is fixed on the workbench of base.
In the such scheme, when carrying out the flame cutting, large caliber bend is placed on the elbow bracing frame; Through the fixing large caliber bend of two locating pieces on the elbow bracing frame; The main shaft that actuating unit drives under the elbow bracing frame rotates, and main shaft drives the elbow bracing frame and large caliber bend rotates, and the flame cutting torch is fixed; Thereby make the flame cutting torch when the processing large caliber bend, make that the large caliber bend end face is smooth.
The beneficial effect of the utility model is, because the dependence actuating unit drives the elbow bracing frame and large caliber bend rotates, and the flame cutting torch is fixed; Make that the flame cutting torch can be when the processing large caliber bend; Guarantee that the elbow end face is smooth, the utility model is simple in structure, and is easily manufactured and invest little.
