Description

Large-scale gyration type part groove frock

Technical Field

The utility model belongs to the technical field of machining, concretely relates to large-scale gyration type part groove frock.

Background

During the machining process of the large-scale rotary part, the quadrant of the part needs to be distinguished through a quadrant line, and the part is clamped and aligned according to the quadrant line. In the processing process, the quadrant line is easy to be removed, unclear, short in length (how long it needs), and the like, so that the quadrant line needs to be engraved or led to a non-processing surface. The method adopts a numerical control machine tool to scribe, and comprises the steps of hoisting, disassembling, clamping and manually operating scribing. When the machine tool is used for scribing, an operator manually operates the machine tool in a JOG (manual rocking wheel) mode, and the phenomena that a scribing knife bumps a workpiece, the scribing depth is too deep and the like can be caused by a small carelessness in the process, so that serious quality problems occur; when the device used in the previous process cannot be used for scribing, the parts need to be detached, secondary clamping and alignment are carried out, scribing errors can be caused due to errors in alignment, subsequent processing deviation can be caused due to wrong reference, quality problems can occur, and meanwhile the process occupies the working time of the machine tool. The method adopts a manual line scribing mode, can finish simpler line drawing and scribing, but when the centripetal line and the lead quadrant line of the large-sized part are drawn and scribed to the non-processing surface with uneven surface and the line is led to the upper end surface and the lower end surface, the problems of non-centripetal, non-collinear lead, non-coincident lead and the like are very easy to occur due to the manual line scribing by a fitter, and the subsequent processing of the part is seriously influenced

SUMMERY OF THE UTILITY MODEL

Based on the above problem, an object of the utility model is to provide a large-scale gyration type part groove frock.

In order to realize the above purpose, the utility model discloses a technical scheme be: the utility model provides a large-scale gyration type part groove frock, includes long board, short board, reference column, groove frame, the perpendicular line scribing board that obtains L shape that sets up of the tip of long board and short board, two reference columns set up on the short edge, and the groove frame sets up between two reference columns, and wherein, the centre of a circle of two reference columns is symmetrical for the inboard straight line of the long board place of line scribing board, and the groove limit of groove frame and the inboard side collineation of long board of line scribing board.

The utility model provides a line scribing frock, it is with it to the method of center line to carve is: the method comprises the steps of placing a scribing plate on the end face of an opening at one end of a large rotary part, enabling one side with positioning columns to face downwards, enabling a long plate to point into the opening of the part, adjusting the position of the scribing plate to enable the two positioning columns to be tangent to the outer surface of the rotary part, enabling scribing edges of a scribing frame to be overlapped with the diameter of the end face of the part according to the principle that a chord perpendicular bisector passes through the circle center, and then fixing a scribing tool to scribe from the scribing frame to a center line.

The method for engraving quadrant lines on the outer part of the rotary part comprises the following steps: with two reference column cards of line scribing board on part one end open-ended terminal surface, the long slab hangs down naturally, adjusts the position of line scribing board to making the long slab outside and the outside butt of part, at this moment, the long slab outside and the outside quadrant line coincidence of part, and fixed frock is followed the long limit outside limit of L type and is carved the quadrant line on the part surface.

Specifically, the centers of the two positioning columns are collinear with the center line of the short edge of the short plate.

Optimized, long board outside limit department sets up and increases the piece, it sets up in the scale board homonymy with the reference column to increase the piece, when establishing the gyration type part of chimb to outside ring and carving the quadrant line, increases the piece height and is used for compensating part surface protrusion height, increases the high adaptation of the height and the outside chimb of part of piece.

The utility model has the advantages that:

the utility model provides a large-scale gyration type part groove frock can realize artifical the machine tool that replaces and carve the work of centripetal line and quadrant line to gyration type part, guarantees the groove precision, improves groove efficiency.
