Description

Technical Field

[0001] The utility model relates to the technical field of motor structure design and manufacturing, in particular to a front and rear flange positioning device for a motor used in a tunneling machine. Background Art

[0002] In order to meet the needs of different markets, it is necessary to develop a variety of flameproof motors, among which tunnel boring machine motors account for a relatively large proportion of flameproof motors, and the demand from users is also increasing day by day. The main part of the appearance of such tunnel boring machine motors is installed in conjunction with the user's main machine. Therefore, there are strict regulations on the appearance and installation dimensions of tunnel boring machine motors during production, which puts higher requirements on welding structural parts. When welding the motor parts, the accuracy and precision of the size requirements and positions must be strictly guaranteed. Now, take the welding of the front and rear flanges of the YBUD-160 / 100 and YBUD-200 / 110 tunnel boring machine motors as an example to analyze and explain: In the original process method, when welding the front and rear flanges, the operator uses a ruler and a bend ruler to measure up and down according to the marking line on the flange to ensure the parallelism of the upper and lower flanges. The drawback of this method is that the maximum scale of the existing straight steel ruler is 1 meter, and the maximum scale of the curved ruler is 0.5 meter. In addition, there are certain errors in pure manual operation. If a longer ruler is used, bending and deformation will inevitably occur during the assembly of live parts. If a longer machine base is encountered, the length of the ruler and the curved ruler cannot be reached, and the problem of non-parallelism of the front and rear flanges is more likely to occur, which will cause the center line of the bracket to be non-perpendicular to the front flange after welding, affecting the accuracy of the bracket hole processing position.
