Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
The components to be welded are a scissor fork (not shown in the figure) which comprises two rectangular pipes, a connecting pipe for connecting the two rectangular pipes and a plurality of shaft sleeves arranged on the rectangular pipes. The most critical link is the positioning and welding of the shaft sleeve.
In the scheme, two rectangular pipes and a connecting pipe are placed on a workbench 8 and are fixed and positioned by a rectangular pipe positioning device 5 and a long pipe positioning device 6 together. When the shaft sleeve is installed, the shaft sleeve outer positioning device 2 and the shaft sleeve inner positioning device 3 are matched together. As shown in fig. 2, the in-sleeve positioning device 3 comprises a driving member and an inner pushing head 32. The external bushing positioning device 2 comprises a driving device 21 and an external push head 23. The driving piece and the driving device 21 can adopt air cylinders to drive the corresponding inner pushing head 32 and the corresponding outer pushing head 23 to push out. The process is numerical control automatic, manual participation is not needed, and the burden on the labor intensity of workers is small. In addition, in the frock assembling process, the installation position of the internal pushing head 32 and the external pushing head 23 has been done the fine tuning by the installation engineer, and the axis collineation of the two sets of four internal pushing heads 32 and the external pushing heads 23 is guaranteed, and subsequent workers do not need manual work to adjust again when operating, can let the axle sleeve on two rectangular pipes guarantee good axiality.
In the present case, the inner pushing head 32 and the outer pushing head 23 are both screw-threaded detachable pushing heads, and a user can be connected with the output rod of the cylinder in a screw-threaded detachable manner, so that shaft sleeves with different sizes can be matched by replacing the pushing heads with different calibers. In addition, after a long time of use, the position of the outer sleeve positioning device 2 may need to be slightly adjusted to some extent, so as to further ensure the coaxiality. Specifically, the driving device 21 is mounted on the mounting seat 22, and one end of the mounting seat 22 is connected with the connecting block 72. Each face of the connecting block 72 is provided with an adjusting elongated slot 721. A positioning block 71 is fixedly arranged on the workbench 8, and a positioning bolt passes through the positioning block 71. The pushing position and direction of the outer pushing head 23 are finely adjusted by the specific position of the positioning bolt on the adjusting long slot 721.
In fig. 2, it is also shown that two bushing inner positioning means 3 are not provided in the two bushing outer positioning means 2, but one inner retention means 4 is provided. The internal retention device 4 comprises an upper barrel 41 extending in a horizontal direction. This part is that in certain specifications of scissors, it is necessary to push the sleeve in one direction. The sleeve inner positioning device 3 is not required to push out the sleeve from the inside to the outside, but the sleeve is displaced when the push-out head 23 pushes the sleeve. The top cylinder 41 is thus placed in this position, against the sleeve from the inside, avoiding the displacement of the sleeve.
As shown in fig. 1 and 3, the long pipe positioning device 6 is mounted at one end of the working table in the length direction, and includes a plurality of mutually independent positioning blocks 61, and each positioning block 61 includes a V-shaped support portion 611 for supporting the connecting pipe of the scissors. The user presses the upper surface of the connection pipe using the pressing mechanism 62. Specifically, the pressing block 621 is provided with a long groove 6211 in the middle, and the fastening nail 622 penetrates through the long groove 6211. The user pushes the pressing block 621, and the pressing block 621 slides to a position right above the connecting pipe relative to the fastening nail 622. The representation of fastener 622 may be threaded such that a user may depress mass 621 by tightening fastener 622.
And a rectangular pipe positioning device 5 is also arranged on the workbench 8 and used for positioning and supporting the rectangular pipe. As shown in fig. 1 and 4, the tube support platform 51 includes a horizontally extending cross-piece 511 for supporting the lower surface of the rectangular tube. The user manually operates the handle 521 to drive the top column 522 to eject, and the top column 522 and the vertical baffle 512 extending in the vertical direction clamp the rectangular pipe to complete positioning.
