Embodiment Construction

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

[0014] The invention provides a hinged part drilling fixture, comprising: a support plate 1, a hexagon head bolt 2, a gasket 3, a long pressure plate 4, a bushing 5, a terminal positioning block 6, a left-biased positioning block 7, Positioning pin 8, hexagon socket bolt 9, short pressure plate 10, adjustment block 11, right-biased positioning block 12;

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

[0016] Install multiple positioning blocks on the support plate 1, the lower surface of the positioning block...

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 hinged part drilling jig. Background technique [0002] The air intake of the aircraft is equipped with multiple hinged parts to adjust the air intake. Worn hinge parts need to be replaced during aircraft maintenance. The hinged part has a shaft hole diameter of 4mm and a length of 700mm. At present, gun drills can only be used to process such deep holes, but during the gun drill process, the swing is large, and the front and rear ends deviate greatly when drilling, and the hinge parts are thin-walled parts, and gun drills are often used to drill holes. The gap phenomenon makes it difficult to realize the manufacture of this hinged part. Contents of the invention [0003] In view of this, the present invention provides a drilling jig for hinged parts, which can solve the problem of drilling deep holes in the manufacturing process of hinged parts. [0004...
