Automatic pipe expanding device for drying frame machining

Abstract

The invention discloses an automatic pipe expanding device for drying frame machining. The device comprises a rack; a first servo motor is fixed on the rack; a first lead screw is fixed to the outputshaft of the first servo motor; the first screw rod is in transmission connection with a first mounting plate; the first mounting plate is in sliding connection with the rack through a linear rail; asecond mounting plate is fixed to the end, far away from the first mounting plate, of the rack; moving mechanisms are arranged on the first mounting plate and the second mounting plate respectively; positioning clamping seats are arranged on the moving mechanisms; a drying frame is clamped to the positioning clamping seats; a pipe expanding mechanism is arranged at the rear side of each positioning clamping seat; an ejecting mechanism is arranged on the side face of each positioning clamping base; an electric control box is arranged on one side of the rack; and the output ends of the electriccontrol box are electrically connected with the input ends of the first servo motor, the moving mechanisms, the pipe expanding mechanisms and the ejecting mechanisms. With the device of the inventionadopted, the transverse pipe and vertical pipe of the drying frame can be rapidly and accurately assembled, and therefore, working efficiency is improved; the transverse pipe is expanded; and therefore, welding quality and mechanical performance are improved.

Description

technical field [0001] The invention belongs to the technical field of automatic tube expansion devices for drying racks, and in particular relates to an automatic tube expansion device for drying rack processing. Background technique [0002] The towel rack is used for hanging towels and bath towels, and the main place of use is the bathroom. It can also be used for beautiful decoration, such as placing flower pots, stacking sundries, etc. Some fully functional towel racks also have the functions of heating, drying, disinfection, and inhibiting the growth of bacteria. [0003] In the production and application of drying racks in the HVAC industry, the plug-in towel rack firstly inserts the horizontal tube into the vertical tube. With the increase of the vertical tube, the dimensional accuracy of the vertical tube aperture and center distance is very high, and the size is slightly deviated. It cannot be inserted into the vertical pipe hole. If the matching gap between the s...

Problems solved by technology

[0004] The purpose of the present invention is to provide an automatic tube expansion device for drying rack processing to solve the problem that the welding and positioning of the existing drying rack in the above background technology is difficult, and the requirements for processing dimensions are strict. After welding, it is easy to cause pressure resistance and The sealing effect is not satisfactory, the rework rate of liquid leakage at the welding position is high, the labor intensity is high, and the production cost is high.
