Gap compensation positioning device and method for fork-shaped part

Abstract

The invention discloses a gap compensation positioning device and method for a fork-shaped part. The device comprises a base, a handle, an adjusting threaded rod, a flange bushing, a forward positioning clamping jaw, a reverse positioning clamping jaw, a plurality of tail end sensors, a micro display and a battery assembly. The tail end sensors are arranged on the forward / reverse positioning clamping jaw, a product positioning hole is formed in the reverse positioning clamping jaw, the forward positioning clamping jaw and the reverse positioning clamping jaw are used in cooperation, the fork-shaped part is arranged on a frame, a part notch and an upper fork lug structure formed after the forward / reverse positioning clamping jaws are combined are sleeved, and a positioning pin is inserted into a fork-shaped part intersection point hole and positioning holes in the forward / reverse positioning clamping jaws for hole-pin matching positioning. The handle on the adjusting threaded rod is rotated, and the forward / reverse positioning clamping jaws are driven by the flange lining to move and open at equal intervals in the reverse direction in the axial direction and are attached to the two inner side faces of the fork-shaped part. After the forward / reverse positioning clamping jaws are attached to the airplane fork-shaped part, the tail end sensors feed back a contact signal, and the contact state is displayed on the micro display.

Description

technical field [0001] The application relates to the technical field of aircraft assembly and manufacturing, in particular to a gap compensation positioning device and a compensation positioning method for fork-shaped parts. Background technique [0002] There are a large number of fork-shaped parts in the aircraft body structure, such as hatches, access covers, and the separation surface between the vertical tail and the fuselage of some models. Their common characteristics are many coordination features and high precision requirements, especially the multiple fork-shaped In the mechanism system where the parts work together, the centering requirement based on the center plane is directly related to the gap compensation ability of the hinge system installation and the flexibility of the axis movement function. [0003] The center surface of the traditional fork-shaped part is positioned by the lug locator. At least 1mm~2mm equidistant gap is left between the lug locator an...

Problems solved by technology

However, in the actual operation process, the notches of different sorties of fork-shaped parts are larger than the theoretical notch size within the tolerance range, the lug positioner is smaller than the theoretical thickness of the lug within the tolerance range, and the clearance values ​​on both sides of the fork lugs of different sorties are also different. In addition, it is difficult and inefficient for workers to manually insert inserts. Therefore, in most cases, thinner, easy-to-insert inserts are selected for gap compensation. The accuracy of the center face is not high, and the fork-shaped parts are prone to be twisted, which has a great impact on the subsequent coordination and installation of the hinge mechanism.
