Description

Front fork vertical shaft press-fitting jig of wheelchair Technical Field The utility model relates to the technical field of jig design, in particular to a front fork vertical shaft press-fitting jig of a wheelchair. Background In the wheelchair manufacturing field, the assembly of front fork frame and vertical scroll is a key link, and in traditional pressure equipment in-process, this company often is difficult to accurate realization owing to lack special tool, and the operating personnel generally need manual to carry out the repeated adjustment to each position of front fork support to ensure that it can be in correct gesture and position when pressure equipment, and this kind of manual operation mode is not only inefficiency, and the error that causes the pressure equipment quality unstable because of manual operation easily influences the wholeness ability and the security of follow-up wheelchair moreover. In addition, for the front fork support of different specification sizes, current device is difficult to adapt to its change fast, and every time change product model is the time, all need spend a large amount of time and energy readjust pressure equipment technology and equipment parameter, has seriously restricted wheelchair production process's flexibility and high efficiency. Therefore, there is a need for a press-fitting jig for a vertical shaft of a wheelchair front fork, which can precisely position, stably fix the front fork bracket and adapt to various specifications. Disclosure of utility model In order to solve the technical problems, the utility model relates to a front fork vertical shaft press-fitting jig of a wheelchair, which has the advantages of simple and reliable structure, effectively solves the technical problems, is suitable for popularization and use, and is realized by the following technical scheme: The utility model provides a front fork vertical scroll pressure equipment tool of wheelchair, includes the bottom plate, the bottom plate is used for being connected with the press mounting equipment frame, be equipped with bilateral symmetry's two stopper on the bottom plate, the stopper is equipped with the side arm complex spacing groove with the front fork support, the axis direction perpendicular to bottom plate of the cylinder supporting part of self behind the side arm and stopper cooperation of front fork support, be equipped with the bracing piece on the bottom plate, the top of bracing piece is contradicted with the bottom surface of cylinder supporting part, the rear portion of bottom plate still is equipped with the riser, the front surface of riser is equipped with a riding block, the one end that the arc supporting part of front fork support crooked extension downwards supports on the riding block, the riser is used for spacing the front fork support from the rear side.
