Embodiment 1

[0024] In this embodiment, the measurement device of the round bar parameter of the present invention is as Figure 1~3 shown. It includes a carriage, an angle sensor, and an encoder. Wherein, the trolley has a platform 2 and four symmetrical rollers 5 installed on the bottom of the platform 2, and the radius of these four rollers 5 is r 1 . The trolley is configured such that when it is placed on a horizontal plane, the four rollers 5 are all in contact with the plane and the platform 2 can remain horizontal. The angle sensor is arranged on the platform 2 for measuring the included angle θ of the platform 2 relative to the horizontal plane. The encoder is arranged on the rotating shaft of the roller 5 and is used to record the number of rotations of the roller 5 .

[0025] During the rotation of the roller 5, since the encoder is arranged on the rotating shaft of the roller 5, it has the same angular velocity as the roller 5, so the number of turns it rotates is exactly t...

Embodiment 2

[0040] In this embodiment, only the differences between this embodiment and Embodiment 1 are described in detail, and the similarities are briefly summarized.

[0041] In order to improve the accuracy of the measuring device of the round bar parameter, in this embodiment, the measuring device of the round bar parameter of the present invention is as Figure 1~3 shown. It includes a trolley, a wheel 3, an angle sensor, and an encoder. Wherein, the arrangement, structure and function of the trolley and the angle sensor are the same as those in Embodiment 1, and will not be repeated here.

[0042] Radius r of runner 3 2 less than the radius r of the roller 5 1 , and, the runner 3 is in contact with one of the rollers 5, and can rotate synchronously under the drive of the roller 5, that is, the linear velocity of the runner 3 and the roller 5 is the same.

[0043] The encoder is arranged on the rotating shaft of the rotating wheel 3 and has the same angular velocity as the rot...

Embodiment 3

[0055] like figure 2 As shown, in this embodiment, in addition to the components described in Embodiments 1 and 2, the measuring device for round bar parameters of the present invention includes first and second angle sensors 6 arranged orthogonally , 7, the first angle sensor 6 is arranged along the left and right directions of the dolly for measuring the inclination angle α between the left and right directions of the dolly and the horizontal plane of the platform 2, and the second angle sensor 7 is arranged along the front and rear directions of the dolly for measuring the front and rear of the platform 2 along the dolly The inclination angle β between the direction and the horizontal plane.

[0056] The measuring device of the round bar parameter in this embodiment is except having the measuring function in embodiment 1,2, can also measure the included angle of the center line of round bar and horizontal line, concrete method is as follows:

[0057] like Figure 4 As sh...

Abstract

The invention provides an apparatus for measuring round bar parameters. The apparatus includes: a trolley which has a platform and 4 rollers which are installed at the bottom part of the platform in symmetry, wherein the radius of each roller is r1 and the trolley is configured such that 4 rollers are in contact with a horizontal plane when the trolley is disposed on the horizontal lane and the platform is horizontally disposed; an angle sensor which is disposed on the platform and is intended for measuring the intersection angles between the platform and the horizontal plane; encoders each of which is installed on a rotation shaft of respective roller and is intended for recording the turns when respective roller rotates. The invention also provides a method for measuring the round bar parameters. According to the invention, the apparatus and the method can easily obtain the radius, the roundness, the cylindricity, the central line angles and the like parameters of a round bar. The apparatus and the method increase the working efficiency of measurement workers and increase the accuracy of measurement result.

Description

technical field [0001] The invention relates to a measuring device and method for parameters of a round bar, in particular to a measuring device and method for the radius, roundness, cylindricity and center line angle of a round bar. Background technique [0002] Round bar parameter measurement is one of the time-consuming process steps for products produced by pipe, rod and wire manufacturers, but because of the importance of this process, it cannot be omitted. At present, the parameters of round bars, such as: internal and external diameter measurement, roundness measurement, cylindricity measurement, etc., are usually used in conjunction with a variety of instruments and equipment, which brings a lot of inconvenience to the measurement work, and during the measurement process, there will also be Due to the joint application of multiple tools, there will be a certain measurement error. [0003] There are some schemes for measuring round bar parameters in the prior art, su...
