Description

Automatic assembly tool for electric wheelchair frame Technical Field The invention relates to the technical field of wheelchair assembly, in particular to an automatic assembly fixture for an electric wheelchair frame. Background The wheelchair frame is a framework of an electric wheelchair, and in the assembly of the wheelchair frame, the wheelchair frame is a core main body structure for connecting, supporting and integrating all other parts together, so that the strength, the stability, the bearing capacity and the basic appearance of the whole wheelchair are determined. When the wheelchair frame is specifically assembled, bearings are needed to be pressed at the two ends of the front fork spacer bush. The conventional process is to weld the front fork, the spacer bush and the frame and then press-fit the bearing. However, because the front fork is inclined and the surface of the frame is not horizontal, the press cannot be used for press mounting, and only the small hammers can be used for knocking in one by one, so that the operation is complex. Through retrieval, chinese patent publication No. CN120839460B discloses a double-shaft press-fitting device in a wheelchair spacer, which comprises a mounting frame, wherein a positioning cone column is arranged at the bottom of the mounting frame, a press-fitting seat is slidably mounted on the mounting frame, the axis of the press-fitting seat and the axis of the positioning cone column are positioned on the same straight line, and a straight line driver is arranged at the top of the mounting frame; the pressing seat comprises a shell, a plurality of inner supporting blocks are slidably arranged at the bottom of the shell towards one side of a positioning cone column, a driving unit is arranged in the shell and drives the inner supporting blocks to synchronously move along the radial direction of the pressing seat, the inner supporting blocks are used for supporting inner rings of bearings arranged at the bottom of the pressing seat, and a pressing frame is fixedly arranged at the working end of the linear driver. According to the device, the plurality of inner support blocks synchronously move along the radial direction of the press mounting seat, so that the bearings with different sizes are fixed, and the lower pressing frame can drive the driving unit to automatically release the support of the inner support blocks to the bearings when in reset, so that the automatic operation of fixing and releasing the fixing of the bearings is realized; in practical use, the bearing press-fitting is needed at two ends of the spacer bush, the device can only press-fit the upper end due to interference between the device and the ground, the bearing press-fitting seat is easy to deflect due to wrist shake and uneven force application in the press-fitting process, the inner wall of the spacer bush is further inclined to be scratched, the positioning cone column can only be matched and centered with a single-end hole of the spacer bush, the problems of ovality, conicity and axial bending of the spacer bush cannot be solved, the spacer bush is free of any rigid support, radial deflection is easy to occur due to stress during press-fitting, and coaxiality errors of the bearing and the spacer bush are large.
