Problems solved by technology

In this way, it is not easy to guarantee the dimensional accuracy, and the processing error is generally around ±0.20mm
Such a large error can only be adjusted by adding shims when the reel is assembled, which has an impact on the accuracy and quality of the quadrangular pyramid sleeve or reel

Embodiment Construction

[0027] Such as image 3 As shown, the measurement dimension P is calculated based on the nominal dimension K and α value, that is, the measurement dimension P is determined by using the dimension K and α value as the reference data, and K is based on the inner hole center 6 of the square pyramid sleeve. The measurement reference guarantees that, for this reason, the present invention still uses the inner hole center 6 of the quadrangular pyramid sleeve as the measurement reference, and at the same time uses the α value as the data that must be considered to find a new simple, controllable and convenient size control method.

[0028] from image 3 It can be seen that as long as the radial and axial dimensions of the highest point of the pyramid 10 are determined, that is, when the dimensions of the side M1 and the top surface M2 of the pyramid 10 are guaranteed, the angle α value of the working inclined plane M3 of the pyramid 10 is guaranteed at the same time , the nominal di...

Abstract

The invention discloses a size control method for precision processing of a pyramid sleeve and a measurement clamping plate; precision processing is carried out to the pyramid sleeve workpiece by adopting the following steps: the first step: the top surface of a pyramid body is milled within an error allowance range, all top surfaces of the pyramid body are symmetrical by taking an inner hole of the pyramid sleeve workpiece as the center, and all top surfaces of the pyramid body are used as radial locating datum planes of the pyramid body; the second step: the side surface of the pyramid bodyis milled within an error allowance range, and is used as an axial locating datum plane of the pyramid body; the third step: the side edge of a measurement port of the measurement clamping plate is identical with the axial locating datum plane of the pyramid body, the bottom side thereof is identical with the radial locating datum plane of the pyramid body, and the working inclined surface of thepyramid body is milled to be identical to the inclined surface of the measurement clamping plate; the pyramid body is processed precisely by adopting the invention, so as to realize accurate control of the size of the pyramid body and meet using rule requirements of the pyramid sleeve; the invention further discloses a measurement clamping plate which is a special tool which used by the method.

Description

technical field [0001] The invention relates to a processing method of a pyramid sleeve of a reel part of a metallurgical machine, in particular to a size control method for finishing the pyramid sleeve, and also relates to a special tool measuring clamping plate used in the method. Background technique [0002] The reel is the main part of the uncoiler and coiler equipment in metallurgical machinery, and the square pyramid sleeve is the core part of the reel. The structure of the rough-processed quadrangular pyramid sleeve is as follows: figure 1 , figure 2 Shown, the surface of quadrangular pyramid cover is provided with some pyramids 10, and when each pyramid is arranged longitudinally along quadrangular pyramid cover, take the axis of rotation of quadrangular pyramid cover as the center circumference even distribution ( figure 1 , figure 2 There are 4 groups of pyramids evenly distributed on the circumference of the quadrangular pyramid sleeve shown, and each group ...
