Problems solved by technology

[0002] Nowadays, there are many connection methods for pipe members, such as self-tapping connection, drilling screw and bolt connection, pipe through-hole penetration bolt connection and welding bonding, etc., but these methods have thin force parts, small fastening area, and easy cross section Deformation leads to small compression force and unsuitable high welding heat, which cannot meet the requirements of high compression force, large contact surface of the force part, tightness and reliability of the fastening part.

Embodiment Construction

[0016] The technical solutions in the embodiments of this patent are clearly and completely described below in conjunction with the accompanying drawings.

[0017] In this embodiment, to measure the deviation of screw holes, the holes on the upper surface of the square tube of the main part are matched with the holes of the connecting parts, so different degrees of radial deviation are produced when distributed along the axial direction of the main pipe. The radial offset size should be measured one by one. Use a steel ruler along the outer edge of one side of the tube as the reference to the center of the hole, and the accuracy can be within millimeters.

[0018] In this embodiment, the steps for adjusting the radial movement adjustment block are: loosen the locking screw of the adjustment block, and shift to the left or right along a 30° oblique direction, and the size is measured from the center of the open end of the nut chuck to the radial offset The distance shall prevai...

Abstract

Disclosed is a device for conveying a positioning nut in an inner cavity of a square tube. The device is mainly composed of a sliding mold body, a radial movement adjusting block, a nut clamping head, a lower nut supporting plate, clamping head screws and a conveying cable. By means of the device, the radial position can be adjusted according to position change of a station hole, the nut can be accurately conveyed to the fixed point in the square tube or a rectangular tube, and the tube is reliably connected with an external workpiece through a bolt and the nut while no self rotation of the nut is kept. The device for conveying the positioning nut in the inner cavity of the square tube is easy to manufacture, convenient to use and maintain and high in safety and reliability. The using requirement of safe and reliable positioning fasteners can be met.

Description

technical field [0001] The invention belongs to the technical field of fastening and connection, and relates to a technology for arranging nuts in square or rectangular straight pipes and tightly fastening them with external connecting parts with bolts and nuts. Background technique [0002] Nowadays, there are many connection methods for pipe members, such as self-tapping connection, drilling screw and bolt connection, pipe through-hole penetration bolt connection and welding bonding, etc., but these methods have thin force parts, small fastening area, and easy cross section Deformation leads to limitations such as small pressing force and unsuitable high welding heat, which cannot meet the requirements of large pressing force, large contact surface, and tightness and reliability of fastening parts. Therefore, in a long and narrow pipeline, the only reliable way is to arrange nuts on one side and connect bolts through the outside. Contents of the invention [0003] The i...
