Abstract
The invention relates to an alignment method for a rotary center of a multi-grinding-head rotary table. The alignment method is characterized by comprising the following alignment processes that (1) a dial indicator is fixed on a workpiece, the workpiece is moved to a machining origin position, the four edges of the rotary table are measured through a measuring head, the radius R of a circumcircle is obtained, the measuring head is moved to the supporting outer circumferential end face of a grinding head to be measured, and a reading is recorded, wherein the transverse-coordinate value of the rotary center of the grinding head to be measured equals movement distance plus the radius R plus the reading; (2) the workpiece is rotated to make the measuring head rotate by a lap around the supporting outer circumferential face, and the grinding head to be measured is moved so that the reading of the dial indicator can keep unchanged after the measuring head rotates by a lap, wherein the longitudinal movement coordinate value of the rotary center of the grinding head to be measured equals a longitudinal-coordinate value, displayed by the system, of the grinding head; (3) in this way, the rotary center of the grinding head to be measured is determined; (4) according to the method, the transverse-coordinate values and the longitudinal-coordinate values of the remaining grinding heads are determined in sequence. The technical requirements of installation and manufacturing are greatly lowered, centralized positioning of the grinding heads can be achieved quickly and accurately, and therefore machining accuracy and product quality are improved.
Description
Technical field
The present invention relates to a kind of centre of gyration aligning method of many bistriques turntable.
Background technology
The continuous processing of many bistriques can obtain higher positioning precision and surface smoothness, applies more and more extensive.And in order to simplify programming, between each bistrique, need a definite centre of gyration.Prior art is that the centre of this flat board has a locating hole, overlaps with the centre of gyration of turntable by manufacturing a large flat board that locating hole is known.This installing plate is made complicated, needs the lathe of degree of precision to complete, and generally needs installer to possess good installation experience and just can reach requirement.Installation site uncertainty due to electric main shaft bistrique during installation causes actual use can not well carry out centering.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of centre of gyration aligning method of many bistriques turntable is provided, reduced the specification requirement of manufacturing is installed, can carry out fast and accurately centering.
For this reason, the present invention takes following technical scheme: a kind of centre of gyration aligning method of many bistriques turntable, it is characterized in that described many bistriques turntable comprises the main turntable that can move left and right, a plurality of bistriques are set on main turntable, main turntable is realized level by rotating mechanism and is rotated freely, the workbench that the sidepiece setting of described main turntable can move horizontally, arranges a turntable that can make workpiece vertical rotary on described workbench, on a turntable, workpiece is set; Centering process is as follows:
(1) first with amesdial, measure, amesdial is fixed on workpiece, workpiece movable is to working origin position, utilize gauge head to measure 4 of turntable edges, obtaining ideal trajectory is circumcircle radius R, and mobile amesdial transverse shifting, moves on the support circle end face of bistrique to be measured gauge head, record reading, distance+R+ reading of the lateral coordinates of tested bistrique centre of gyration value=movement;
(2) amesdial gauge head is placed on the support outer circumference surface of tested bistrique, turning of work piece, gauge head rotates a circle around supporting outer circumference surface, mobile bistrique to be measured is along the longitudinal movement, make the gauge head amesdial reading that turns around constant, the along slope coordinate value of the centre of gyration of bistrique to be measured is that the bistrique that current system shows vertically moves coordinate figure;
(3) centre of gyration of bistrique to be measured is determined thus, adds man-hour first along the horizontal and vertical centre of gyration that moves to, then rotates processing;
(4) according to said method, determine successively the horizontal and vertical coordinate figure of residue bistrique.
Adopt bistrique aligning method of the present invention there is no locating hole requirement to flat board is installed, only require Primary Location, greatly reduce the specification requirement of manufacturing is installed, also can quick and precisely realize the centralized positioning of bistrique, improve machining accuracy and product quality.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention.
Fig. 2 is the structural representation of bistrique centre of gyration O ' of the present invention.
Specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.
The centre of gyration aligning method of a kind of many bistriques turntable as shown in Figure 1-2, many bistriques turntable comprises the main turntable 1 that can move left and right, three bistriques 5 are set on main turntable 1, it is M2 direction that main turntable 1 realizes by rotating mechanism that level rotates freely, the workbench 4 that the sidepiece setting of main turntable 1 can move horizontally, a turntable 3 that can make workpiece vertical rotary is set on workbench 4, prop up on turntable 3 workpiece 6 is set, workpiece 6 possesses a working origin X, the centre of gyration is at O point, along the M2 direction of motion, move, desirable rotary motion trace 2 is as shown in broken circle, and centering process is as follows:
(1) first with amesdial, measure, amesdial is fixed on workpiece, workpiece movable is to working origin position, utilize gauge head to measure 4 of turntable edges, obtaining ideal trajectory is circumcircle radius R, and mobile amesdial transverse shifting is M1 direction, and gauge head is moved on the support circle end face of bistrique to be measured, record reading, distance+R+ reading of the lateral coordinates of tested bistrique centre of gyration value=movement;
(2) amesdial gauge head is placed on the support outer circumference surface of tested bistrique, turning of work piece, gauge head rotates a circle around supporting outer circumference surface, it is M3 direction that mobile bistrique to be measured is along the longitudinal movement, make the gauge head amesdial reading that turns around constant, the along slope coordinate value of the centre of gyration of bistrique to be measured is that the bistrique that current system shows vertically moves coordinate figure;
(3) centre of gyration of bistrique to be measured is determined thus, adds man-hour first along the horizontal and vertical centre of gyration that moves to, then rotates processing;
(4) according to said method, determine successively the horizontal and vertical coordinate figure of residue bistrique.
It needs to be noted, the mode of above-described embodiment only limits to describe embodiment, but the present invention is confined to aforesaid way incessantly, and those skilled in the art can modify easily accordingly in not departing from the scope of the present invention, therefore scope of the present invention should comprise disclosed principle and the maximum magnitude of new feature.
