Embodiment Construction

[0022] There are left top 2 and right top 8 on the working platform 6, the working platform 6 is slidingly connected to the workbench 7, the motor 1 is connected to the left top 2 in rotation, the photoelectric encoder 9 is fixedly connected to the right top 8, and a tappet displacement measuring device 3. Tappet-type displacement measuring device 2 4. Tappet-type displacement measuring device 3 5 is fixedly connected to the workbench 7 respectively.

[0023] figure 1 It is a schematic diagram of the long-axis workpiece measurement of the straightening machine. The two tops can hold the long-axis workpiece 10, and the working platform 6 can move the long-axis workpiece 7 to the left or right to realize the measurement of different measurement points of the long-axis workpiece. 1 drives the left top 2 to realize the rotation of the long-axis workpiece 7, and the right top 8 follows to drive the photoelectric encoder 9 to rotate.

[0024] The invention works like this:

Abstract

The present invention relates to a radial runout measuring device for a straightening machine long axis workpiece, and belongs to the field of straightening machine manufacturing. According to the device, a left top tip and a right top tip are arranged on a work platform; the work platform forms a slidable connection with a work table; a motor forms a rotary connection with the left top tip; a photoelectric encoder and the right top tip are fixedly connected; and a tappet type displacement measuring device 1, a tappet type displacement measuring device 2 and a tappet type displacement measuring device 3 are respectively and fixedly connected with the work table. The method and the device of the present invention have the following advantages that: the full automatic measuring calculations of the whole radial runout and the local radial runout of the long axis workpiece on the straightening machine can be achieved, such that the total length radial runout measurement and the local radial runout measurement of the long axis workpiece can be achieved while the cost can be reduced; the method is simple and universal.

Description

technical field [0001] The invention belongs to the field of straightening machines. Aiming at the radial runout measurement technology of long-axis workpieces, a measurement method is mainly proposed, which is applied to the radial runout measurement of the overall and local heat treatment of long-axis workpieces of factory straightening machines. Background technique [0002] At present, when domestic straightening machines straighten long-axis workpieces, the radial runout of long-axis workpieces over 3 meters is mainly measured by manual dial indicators. High points, then straighten the high points on the press. Since the workpiece is relatively long, there will be many bends on the workpiece, and the degree and direction of the bends are different. Therefore, this method has extremely high requirements on the operator, and the measurement accuracy is very low, and often the current point is aligned. Other points have problems and are out of tolerance. Straightening a ...
