Summary of the invention
The objective of the invention is to in the prior art described in the background technology; When large-scale workpiece is processed the inner conic hole of little tapering; Can't in process, measure accurately and control for the size of inner conic hole; Cause the underproof problem of workpiece easily, a kind of cone tank measuring method of in workpiece process, conveniently the inner conic hole size being measured is provided.
Design of the present invention is following: if with a kind of measurer of special use; Can after the semifinishing of inner cone grooved, measure and definite surplus; And can carry out feed processing according to the data of surplus, the convenient data of directly measuring grooved so just can improve machining efficient after the moulding; Cut down finished cost, the more important thing is the quality that can be good at guaranteeing product.
The technical scheme that can realize goal of the invention of the present invention is following:
A kind of cone tank measuring method, it comprises the steps:
Step 1, according to the measurement block that the grooved of Machine Design is made identical tapering, the width of measurement block and height dimension are slightly less than the size of cone tank;
Step 3; Measurement block is put into from the end of the cone tank of standard component in the cone tank of standard, and the turn screw sheel extends on the bottom surface of cone tank the lower end of screw mandrel; And the fixing primary data on the dial sleeve of record, with this primary data as reference data;
Step 4; Measurement block is put in the groove from the end of to be measured cone tank, the both sides hypotenuse of measurement block and the side of cone tank are pressed close to the turn screw sheel; The lower end of screw mandrel is extended on the bottom surface of the cone tank of processing, and fixedly reading data on the dial sleeve;
Draw to be measured behind the allowance on the degree of depth in step 5, calculate to be measured the allowance on taper surface through formula, computing formula is △ X=2 △ Htg
a/ 2,
Wherein △ X is the horizontal allowance of taper surface, and △ H is the allowance of depth direction, and a is the number of degrees of the drift angle of cone tank, i.e. tapering.
The instrument of special-purpose measurement cone tank in the above-mentioned cone tank measuring method; It comprises measurement block, fixedly dial sleeve, screw sheel and screw mandrel, and screw mandrel is fixedly connected with screw sheel, and measurement block lower end conical surface angle is corresponding with the conical surface angle of standard workpiece to be detected; Measurement block is fixedly connected with fixing dial sleeve; The measurement block center is provided with screwed hole, and screw mandrel passes this screwed hole, and extends to the below, bottom surface of measurement block.
In order to limit the rotation that causes measurement block when screw mandrel rotates, described measurement block comprises bar portion and head, and bar portion is square.
The advantage of cone tank measuring method of the present invention is: cone tank measuring method of the present invention can be processed the size that detects cone tank in the process of cone tank at workpiece, and calculates the allowance of cone tank, makes things convenient for its processing; This detection mode can onlinely detect, and need workpiece not got on down from machining tool, has improved working (machining) efficiency; And reduced energy resource consumption; Because three coordinates measuring equipment costs an arm and a leg, adopt that the disclosed instrument that is used to measure cone tank detects among the present invention, accuracy is high; Easy and simple to handle and cost is very low, be more suitable in large-scale promotion application.
