Abstract
The invention relates to a detector for concentricity of a workpiece, comprising a seat body, wherein the axis of the seat body is provided with a guide rod capable of axially moving; one end of the guide rod stretches out of the seat body and is provided with a roller wheel horizontally placed, and the other end of the guide rod and a collision block protruding out of the seat body form into a whole; the collision block is abutted and located by a spring arranged oppositely; the surface of the seat body is provided with two overtravel-limit switches; and collision rods of the two overtravel-limit switches are respectively arranged at two sides of the collision block in a clearance mode. The detector of the invention is fixedly arranged on a vertical lathe, and the concentricity of each point on the outer profile line of the processed workpiece is detected in real time so as to assist an operator to correctly judge whether the position for placing the workpiece is accurate and the concentricities of the outer profile line are consistent. The invention has time and labor saving and high efficiency, even though the common operator processing can conveniently and separately finish the processing and operation task.
Description
[technical field]
The invention belongs to a kind of concentricity meter, especially belong to a kind of concentricity meter of cylindrical work.
[background technology]
Vertical lathe is when processing column shape workpiece, and whether workpiece is put into station accurate, and whether the concentricity of workpiece self outer contour correctly be vital two factors, otherwise, will influence crudy.At present, place work piece, and the concentricity of detection workpiece outer contour has several different methods.High-grade machined into adopts the manipulator place work piece, and therefore, the placement factor generally can not cause workpiece concentricity difference to occur, but investment is big, processing cost is high; Adopt infrared detector, finish detection, have complex structure equally by transmitter, acceptor device, the problem that cost of investment is high, domestic medium-sized and small enterprises generally are difficult to accept.Domestic usual way be operating personnel by rule of thumb, use scale and detect the concentricity of cylindrical work earlier, then, the placement of making this workpiece in view of the above whether precisely, the whether corresponding to judgement of the concentricity of outer contour, each workpiece all will so repeat, the efficient that wastes time and energy is low, and to operating personnel's specification requirement height, general personnel can't independently finish at all.
[summary of the invention]
For overcoming the prior art above shortcomings, the present invention aims to provide a kind of detector for concentricity of workpiece, it is simple in structure, cost of investment is low, be installed on the vertical lathe, can detect in real time easily the cylindrical work placement location whether precisely, whether the outer contour concentricity consistent, thereby the auxiliary operation personnel make correct judgement, time saving and energy saving efficient height.
For achieving the above object, the present invention has adopted following technical scheme: the structural feature of this detector for concentricity of workpiece is: comprise a pedestal, being equipped with one on the axis of pedestal can axially movable guide rod, the roller that one end of guide rod stretches out pedestal and has a horizontal positioned, the collision block that the other end of guide rod and protrudes from the pedestal surface constitutes one, and collision block compresses the location by a spring that is provided with in opposite directions; Be provided with two travel switches on described pedestal surface, the lance of described two travel switches clearance-type respectively is arranged on the both sides of collision block.
During concrete enforcement, described two travel switches, wherein a front travel switch is fixed installation, travel switch is adjustable location and installation behind the another.
Beneficial effect: the present invention, improves the angle of working (machining) efficiency and sets out from simple and easy, convenient especially at vertical lathe processing column shape workpiece, formulates out a kind of cylindrical work concentricity meter.This instrument is fixedly mounted on the vertical lathe, concentricity situation by each point on the outer contour of real-time detection workpiece to be machined, whether the auxiliary operation personnel are accurate to the placement location of workpiece, whether the outer contour concentricity is consistent, make correct judgement, time saving and energy saving efficient height makes common operating personnel also can finish the processing operation conveniently and independently.
For deepening the understanding of the present invention, below by embodiment also in conjunction with the accompanying drawings, the present invention is described in further detail.
[description of drawings]
Fig. 1 is the perspective view of one embodiment of the invention.
Among the figure: guide rod 1, roller 11, roller shaft 12, collision block 13; Pedestal 2, pedestal groove 21, pedestal rear portion 22; Front travel switch 3, lance 31, lance wheel 32, fixing hole 33; Back travel switch 4; Spring 5.
[specific embodiment]
Referring to Fig. 1.The detector for concentricity of workpiece of present embodiment, by guide rod 1, pedestal 2, front travel switch 3, back travel switch 4, collision block 13 and spring 5 are formed.Pedestal 2 is the tube bundle with square section that has through hole on the axis, and through hole has pedestal groove 21 at the top of pedestal 2.Guide rod 1 is " L " type bar of a horizontal positioned, and the one end is a measuring junction, and measuring junction has the roller 11 of a roller shaft 12 location, and the outline of roller 11 protrudes the end face at guide rod 1.The shaft of guide rod 1 is inserted in the through hole of pedestal 2, and its other end is vertical with collision block 13, and constitutes one.The single piece that collision block 13 and guide rod 1 constitute can be done front and back to moving in pedestal groove 21.Collision block 13 is by spring 5 oriented towards one another that are arranged in the pedestal rear portion 22.
On the surface of the pedestal 2 of pedestal groove 21 front and back positions, fixedly installed front travel switch 3 respectively through fixing hole 33, back travel switch 4, wherein, back travel switch 4 is done adjustable fixedly installing, and adjusts with convenient.Two travel switches are the roller type travel switch, and the lance wheel 32 of lance 31 is all towards collision block 13.
During operation, the roller 11 of guide rod 1 is pressed on the outer surface of measured workpiece, owing to compress collision block 13 is moved to left to the middle part of pedestal groove 21, at this moment, all leaves the gap between the lance wheel 32 of front travel switch 3 and back travel switch 4 and the collision block 13.Along with the rolling of roller 11 at the outer surface of measured workpiece, if the outer surface of measured workpiece occurs uneven or because the workpiece placement location does not precisely cause outer surface concentricity difference, collision block 13 will clash into the lance wheel 32 of lance 31 thereupon, contact in the travel switch is moved rapidly, send and report to the police or cut off the electricity supply.Operating personnel can make corresponding processing according to actual conditions, or adjust the placement location of measured workpiece, or change measured workpiece, in order to avoid substandard products are done inaction processing.
