Abstract

The utility model discloses a broacher comprising a broacher body, a slide carriage, a broach, a broach collet and a workbench. The broach collet is fixed at the top end of the slide carriage, clampsthe broach and is located above the broach; the workbench is fixed on the broacher body and located below the broach; and the centre of the broach collet, the broach and the workbench is located on the same axes. In the utility model, scrap iron generated by cutting directly falls on the ground in place of entering the broach collet during processing so as to prevent deflection of the broach. Theutility model effectively ensures the processing precision after a period of long-time use, prevents abrasion of the collet and the broach handle, and has long service life and stable performance.

Description

A kind of broaching machine
Technical field
The utility model relates to a kind of broaching machine.
Background technology
Broaching machine is widely used in field of machining as the lathe that uses broaching tool as workpiece processing tool through hole, plane and profiled surface.But the chuck that is used to clamp broaching tool on the existing broaching machine all is the below that is in broaching tool, and the workbench that is used to place workpiece then is in the top of broaching tool.When workpiece was handled, the broaching iron filings that workpiece produced were easy to fall into the slit between chuck and broaching tool, owing to the influence of iron filings, will make cutter produce, and added just might produce deviation man-hour, thereby directly had influence on crudy.
The utility model content
Existing broaching machine is existing to make broaching tool generation deflection because iron filings enter pulling chuck adding man-hour in order to solve, and causes adding the man-hour broaching tool and locatees inaccurate problem, and the utility model provides a kind of and adding man-hour, and iron filings can not enter the broaching machine of pulling chuck.
The scheme that the utility model solves the problems of the technologies described above is: a kind of broaching machine, comprise lathe bed, slide carriage, hydraulic piston device, broaching tool, pulling chuck and workbench, described hydraulic piston device is fixed on the lathe bed, described slide carriage one side is provided with described pulling chuck, opposite side is connected with the piston of described hydraulic piston device, described broaching tool one end is installed on the described pulling chuck, the other end is in the top that is arranged at the workbench on the lathe bed, and the center of described pulling chuck, broaching tool and workbench is on the same axis.
Technique effect of the present utility model is: pulling chuck is clamped broaching tool from the top, and workpiece is in the below of broaching tool.Adding man-hour, the iron filings that cutting is produced directly drop on the ground, and can not enter pulling chuck, also just can not make broaching tool produce deflection.Machining accuracy of the present utility model also can effectively guaranteed after long-time the use, and chuck and broaching tool handle of a knife are not easy to wear yet, long service life, stable performance.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the pulling chuck structural representation of existing broaching machine, and wherein 1 is broaching tool, and 2 is pulling chuck, and 3 is iron filings;
Fig. 2 is a structural representation of the present utility model, and wherein 1 is broaching tool, and 2 is pulling chuck, and 4 is slide carriage, and 5 is workbench, and 6 is lathe bed, and 7 is hydraulic piston device;
Fig. 3 is a pulling chuck structural representation of the present utility model, and wherein 1 is broaching tool, and 2 is pulling chuck.
The specific embodiment
Referring to Fig. 1, the pulling chuck 2 of existing broaching machine is in broaching tool 1 below, and workpiece is in the top of broaching tool 1, is adding man-hour, and broaching tool 1 moves upward workpiece is cut.The iron filings 3 that add under cutting man-hour fall into pulling chuck 2 easily, and this produces crooked with regard to making broaching tool 1 be subjected to the influence of iron filings, so that produce deviation man-hour adding, thus the crudy of having influence on.
Referring to Fig. 2, Fig. 3, lathe bed 6 of the present utility model is the box-shaped welded-steel plate construction, and hydraulic piston device 7 is housed on it, and a side of slide carriage 4 is connected to the piston of hydraulic piston device 7.Pulling chuck 2 is fixed in the opposite side of slide carriage 4, and the below of pulling chuck 2 is clamped and be in to broaching tool 1 by pulling chuck 2, and workbench 5 is in the broaching tool below, and the center of pulling chuck 2, broaching tool 1 and workbench 5 all is on the same axis.Adding man-hour, workpiece is positioned on the workbench 5, hydraulic piston device 7 drives slide carriage 4 and moves down, slide carriage 4 drive pulling chucks 2 and broaching tool 1 move downward broaches, the iron filings that produced will drop to the ground and can not enter pulling chuck 2, just broaching tool 1 can be do not had influence on yet, the accurate of broaching machine processing can be guaranteed effectively.
