Problems solved by technology

[0002] In mechanical processing production, the traditional common methods of calibrating the cylinder are: 1. Repeatedly calibrating the circle through the plate rolling machine; 2. The operator uses a hammer to beat the cylinder with a hammer based on experience, which is low in work efficiency and labor-intensive.
The above two calibration processes are complicated and the production cost is high

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 As shown in -3, the quick correction cylinder tool of the present invention includes a piston rod indenter 1, a tapered mandrel 2, a support block 3 and a bottom plate 5. The cone-shaped mandrel 2 is fixed on the piston rod head 1 of the hydraulic press, and the four support blocks 3 are evenly loaded into the cylinder 4 that needs to be rounded. The head 1 goes down, and the tapered mandrel 2 enters the inner tapered hole of the support block 3, so that the support block 3 moves radially from the inner diameter of the cylinder 4 to the outer diameter, so that the cylinder 4 is evenly stressed, and the cylinder 4 is completed. Correction. The support surface of the support block 3 is an arc surface adapted to the inner diameter of the cylinder body 4 . The tapered mandrel 2 is cylindrical with a chamfer at the front...

Abstract

The invention belongs to the technical field of cylinder body roundness correction and particularly relates to a tool rapidly correcting a cylindrical workpiece. The tool comprises a piston rod pressing head, a conical central spindle, supporting blocks and a bottom plate. The conical central spindle is fixed to the piston rod pressing head of a hydraulic machine. The four supporting blocks are evenly arranged in a cylinder body which needs roundness correction. The cylinder body is vertically arranged on the bottom plate. The supporting faces of the supporting blocks are arc faces matched with the inner diameter of the cylinder body. The conical central spindle is in a cylindrical shape, and the front end of the conical central spindle is provided with a chamfer. During use, the hydraulicmachine is started, the piston rod pressing head moves downwards, the conical central spindle enters an inner cone hole formed by the four supporting blocks so that the supporting blocks can do radial motion in the direction from the inner diameter to the outer diameter of the cylinder body, the cylinder body can be evenly stressed, and correction of the cylinder body is completed. During practical use, the cylindrical workpiece can be rapidly corrected, safety and reliability are achieved, the cost is low, and efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of cylinder circle calibration, and in particular relates to a tool for quickly correcting cylinder parts. Background technique [0002] In mechanical processing production, the traditional common methods of calibrating the cylinder are: 1. Repeatedly calibrating the circle through the plate rolling machine; 2. The operator uses a hammer to beat the cylinder with a hammer based on experience, which is low in work efficiency and labor-intensive. . The above two kinds of circle adjustment processes are complicated and the production cost is high. Contents of the invention [0003] The purpose of the present invention is to provide a quick correction cylinder tool to overcome the above-mentioned shortcomings in the prior art. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A tool for quickly correcting cylindrical parts, including a piston r...
