Embodiment Construction

[0015] The embodiment of the drilling device of the hexagon bolt of the present invention: as Figure 1 to Figure 5 As shown, the drilling device is mainly composed of a clamping mechanism and a clamping block 2, wherein the clamping mechanism is mainly composed of a U-shaped support seat 3 and a locking bolt 4 pierced on one side wall of the support seat 3, and The clamping block 2 is located in the opening of the support base 3. The clamping block 3 is provided with mounting holes 5 which are perpendicular to the side walls on both sides of the support base 3 for the hexagonal bolts 1 to be inserted into. The clamping block 2 is located close to the locking bolts. One end of 4 is provided with an in-line mounting groove 5-1 that communicates with the mounting hole 5 and is used for embedding the head of the hexagonal bolt 1. The groove walls on both sides are attached to each other, and the limit surface can be squeezed and fit with the end face of the head of the hexagonal ...

Abstract

The invention relates to a drilling device of a hexagon bolt. The drilling device comprises a clamping block, a mounting hole and a mounting groove on the clamping block, wherein the clamping block is provided with the mounting groove communicated with the mounting hole at one end of the clamping block; the mounting groove is provided with at least two groove walls adhered to two opposite sides of a head part of the hexagon bolt and a limiting face which is arranged at a communication part of the mounting groove and the mounting hole; the clamping block is provided with a guide hole and a cutter back-off channel; the guide hole and the cutter back-off channel are communicated with the mounting groove, respectively; and the drilling device further comprises a clamping mechanism for arranging the clamping block and the hexagon bolt in the clamping mechanism, and pressing and matching with an end face of the hexagon bolt and the limiting face. When the drilling device is used, a drill bit can machine an anti-loosening hole at the head part of the hexagon bolt through the guide hole; and meanwhile, a groove wall of the mounting groove is adhered to side faces at two opposite sides of the head part of the hexagon bolt, so that the mounting groove can ensure that the head part of the hexagon bolt is prevented from rotation in a drilling process, and the machining error in the drilling process is avoided.

Description

technical field [0001] The invention relates to a drilling device for hexagonal bolts in the field of machining. Background technique [0002] Hexagon bolts are widely used in the fields of aviation, aerospace and defense due to their good positioning and anti-loosening effects. The relevant standards of hexagonal bolts have special requirements for their positioning accuracy and dimensional consistency, that is, the slot size, hole size and shape error of hexagonal bolts must be controlled within a certain tolerance range, so the hexagonal bolts on the The anti-loosening hole processing method is extremely important. Since the anti-loosening holes run through the opposite sides of the hexagonal head of the hexagonal bolt, clamping the hexagonal bolt with a vise will deform the head of the bolt, and in general, milling or conventional drilling is often used to process the hexagonal When the anti-loosening hole on the bolt is used for milling, because the positioning of the...
