Abstract
The invention relates to a centering device for machining. The centering device is mounted on a spindle of a machine tool and comprises a cutter handle, with a blind middle hole, connected with the spindle of the machine tool. A piston rod extending out of the blind hole is disposed in the blind hole. A support spring is disposed between the piston rod and the inner end face of the blind hole. A limit block for limiting the piston rod is disposed on the cutter handle. A magnetic base dial indicator is disposed on the machine tool. A handle which is contacted with the dial indicator is disposed on the part, located outside the cutter handle, of the piston rod. By indication of the dial indicator, centers of workpieces are determined, the indication of the dial indicator is objective and simple, and an operator only needs to move the piston rod and observe the indication of the dial indicator to find out the centers of the workpieces fast and accurately. Compared with the traditional three-point method, the centering device is simple and convenient to operate, higher in centering efficiency and more convenient.
Description
Technical field
The present invention relates to a kind of workpiece centering isolated plant, particularly cylindrical workpiece machining center searching device, belong to the cutting-tool engineering field.
Background technology
Cylindrical work adds man-hour at horizontal Machining centers, be often to forward again horizontal Machining centers processing after cylindrical has processed to, when peripheral milling oil groove etc., at first need the centering workpiece centre, line-of-sight course centering center is adopted in existing alignment usually, and the time is long and the operative employee is had relatively high expectations.
Summary of the invention
The present invention is directed to defects, it is a kind of simple in structure that purpose is to provide, short a kind of machining center searching device consuming time easy to operate.
The technical solution used in the present invention is for this reason: the present invention is arranged on machine tool chief axis, comprise that mesopore is the handle of a knife that is connected with machine tool chief axis of blind hole, be provided with the piston rod that stretches out from blind hole in blind hole, establish support spring between piston rod and blind hole inner face, handle of a knife is provided with the limited block of limiting piston bar; Lathe is provided with the magnet base dial gauge, and the position that is on described piston rod outside handle of a knife is provided with the handle that contacts with described magnet base dial gauge.
Described piston rod is provided with dive key; Limited block is end cap, is connected by screw on the handle of a knife outer face; Handle is vertically set on piston rod.
Advantage of the present invention is: the present invention determines the center of workpiece by the reading of dial gauge, and the dial gauge reading is objective simple, and the operator only needs by the mobile piston bar and observes the dial gauge reading and can look for fast and accurately workpiece centre; This method is easy to operate and simple with respect to traditional line-of-sight course, and its to look for efficient higher more easy.
Description of drawings
Fig. 1 is structural representation of the present invention.
In figure, 1 is that handle of a knife, 2 is that handle, 3 is that piston rod, 4 is that end cap, 5 is that dive key, 6 is that spring, 7 is that magnet base dial gauge, 8 is that machine tool chief axis, 9 is cylindrical workpiece.
The specific embodiment
Handle of a knife 1 mesopore of the present invention is blind hole, and the blind hole inner face is provided with spring 6, and spring 6 supports one and is arranged in blind hole and from its piston rod that stretches out 3 by dive key 5; Described handle of a knife 1 front end face is provided with the end cap 4 that is connected by screw thereon, and end cap 4 is as the use of limiting piston bar 3.
Piston rod 3 front ends of the present invention are provided with one handle 2 and perpendicular with piston rod 3, and handle of a knife 1 integral installation is on lathe; Lathe is provided with magnet base dial gauge 7, and magnet base dial gauge 7 thimbles contact with handle 2.
the course of work of the present invention is: the handle of a knife 1 of first spring 6 being packed into, be contained in dive key 5 on piston rod 3 again and fill in handle of a knife 1, by screw, end cap 4 is contained on handle of a knife 1 end face, make piston rod 3 be withstood gland by spring 6, then handle 2 is screwed on piston rod 3, the machine tool chief axis of at last this handle of a knife 1 integral body being packed into, and magnet base is inhaled on main shaft, magnet base dial gauge 7 heads on handle 2, main shaft is done and is moved left and right, the distance that piston rod 3 stretches out changes thereupon, the reading of magnet base dial gauge 7 also changes thereupon, external diameter maximum due to cylindrical workpiece 9 centers, the center of magnet base dial gauge 7 readings cylindrical workpiece 9 when the highest, thereby realize that processing column body workpiece 9 looks for RC function.
