Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] Such as figure 1 , figure 2 As shown, the automatic measuring device of the present invention includes a positioning detection mechanism, a driving mechanism and a base 8, wherein two mutually parallel linear guide rails 7 are installed on the base 8, and the positioning detection mechanism is installed on the linear guide rails 7 of the base 8, and the The driving mechanism is installed on the base 8, the positioning detection mechanism is connected with the driving mechanism, and is driven to reciprocate horizontally along the linear guide rail 7 by the driving mechanism.

[0024] The driving mechanism includes a servo motor 1, a ball screw 2 and a screw nut 3, wherein the two ends of the ball screw 2 are respectively connected to the base 8 in rotation, and the end of the ball screw 2 away from the tube material 9 to be tested passes through the b...

Abstract

The invention relates to length measurement equipment, particularly to pipe material length automatic measurement devices and a measurement method thereof. Each of the two pipe material length automatic measurement devices comprises a positioning detection mechanism, a driving mechanism and a base. The positioning detection mechanism and the driving mechanism are arranged on the base. The positioning detection mechanism which is connected with the driving mechanism is driven through the driving mechanism to perform reciprocating motion on the base. The measurement method includes that the bilateral sides of pipe materials to be measured are respectively provided with an automatic measurement device and a distance between zero points of the two automatic measurement devices is known; the positioning detection mechanism of each of the two automatic measurement devices moves towards a direction of the pipe materials to be measured and stops when end faces which are arranged at two ends of the pipe materials to be measured are detected to obtain respective displacement distances of the bilateral positioning detection mechanisms; and the distance between the zero points of the two automatic measurement devices subtracts the respective displacement distances of the bilateral positioning detection mechanisms to obtain a length of the pipe materials to be measured. The pipe material length automatic measurement devices have the advantages of achieving length automatic measurement and being simple in structure. The measurement method of the pipe material length has the advantages of saving time and effort and achieving rapid and reliable detection.

Description

technical field [0001] The invention relates to length measuring equipment, in particular to an automatic measuring device and a measuring method for the length of pipe material. Background technique [0002] Large-diameter thick-walled industrial pipes play an important role in industrial production. This type of pipe is made of thick steel plates crimped and welded. The length measurement of each section of welded pipe has always been an urgent problem for steel pipe processing enterprises. The traditional length measurement method is measured by the operator with a tape measure. This method mainly has the following disadvantages: [0003] 1. More than two people are required to cooperate, and the operation is cumbersome; [0004] 2. The method of manually reading the tape will bring artificial reading errors; [0005] 3. After the manual reading, it needs to be manually entered into the computer, which is prone to errors. [0006] Under the general trend of industrial...
