Abstract

The invention discloses a hinge type part drilling clamp. The hinge type part drilling clamp can solve the deep hole drilling problem in the hinge type part manufacturing process. The hinge type part drilling clamp comprises a supporting plate, positioning blocks, bushes and pressing plates. Positioning step faces are arranged on the upper surface of the supporting plate. The positioning blocks are fixedly installed on the supporting plate through the positioning step faces. The hollowed-out portions of the positioning blocks are matched with the axle hole broken portions of hinge type parts. Positioning holes are formed in the positioning blocks on the two sides of the hollowed-out portions. The bushes are embedded in the positioning holes. The pressing plates used for fixing the hinge type parts are further arranged on the positioning blocks and the supporting plate. According to the hinge type part drilling clamp, the axes of the positioning holes of the positioning blocks are limited on the same straight line through steps; and a drill bit is guided and positioned segment by segment in a segmented positioning manner, it is guaranteed that the drill bit will not deviate from the axes all the time, and therefore the problem of deep hole drilling of the hinge type parts is solved.

Description

Technical field

[0001] The invention relates to the technical field of aviation equipment repair, in particular to a hinge type part drilling fixture. Background technique

[0002] A number of hinged parts are installed in the air intake of the aircraft to adjust the air intake. Worn hinge parts need to be replaced during aircraft maintenance. The shaft hole diameter of the hinge part is 4mm and the length is 700mm. At present, only gun drills can be used to process this type of deep hole, but the swing during gun drilling is large, and the front and back ends of the drilling are relatively large. Hinge parts are thin-walled parts, and gun drilling often occurs The gap phenomenon makes it difficult to manufacture such hinged parts. Summary of the invention

[0003] In view of this, the present invention provides a hinged part drilling fixture, which can solve the problem of deep hole drilling in the manufacturing process of hinged parts.

Embodiment Construction

[0013] The present invention will be described in detail below with reference to the drawings and embodiments.

[0014] The present invention provides a hinge type parts drilling fixture, which includes: a support plate 1, a hexagonal head bolt 2, a gasket 3, a long pressing plate 4, a bushing 5, an end positioning block 6, a left-offset positioning block 7, Positioning pin 8, inner hexagonal bolt 9, short pressing plate 10, adjustment block 11, right-offset positioning block 12;

[0015] The upper surface of the support plate 1 is designed to be step-shaped, and the upper, lower and side surfaces of the step are finished, and the parallelism and straightness reach IT7 accuracy according to GB1800-79. The side surface of the step is the reference for installing the positioning block, so that the positioning hole of the positioning block can be located on a straight line.

[0016] A number of positioning blocks are installed on the support plate 1. The lower surface of the positionin...
