A drilling method and drilling auxiliary tooling for parts with evenly distributed oblique through holes on multiple surfaces

Abstract

The present invention discloses a drilling method and auxiliary drilling tool for a part with evenly distributed oblique through holes on multiple surfaces. The drilling method comprises: using the auxiliary drilling tool for the part with evenly distributed oblique through holes on multiple surfaces to quickly transpose the part on an oblique block and drill the oblique through holes on multiple surfaces. Because the force generated by the mating section and the pressing through hole is greater than the force generated by the diamond through hole and the diamond section, during transposition, the drilling template, part, and positioning column are quickly pulled out of the diamond through hole of the oblique block by prying the oblique surface, and then slid and disassembled for transposition. This solves the problem of requiring slow rotation to release the threaded connection and reversing, which prevents the part from quickly transposing and drilling on the oblique surface base. The oblique through holes on the next surface of the part are then drilled, thereby improving the processing efficiency of the part.

[0002] In order to meet the needs of the parts in use, oblique through holes leading to the central through hole are evenly distributed on multiple surfaces of the outside of the parts. The parts are clamped on the drilling machine directly using a vise, etc. The drill bit cannot be tilted with the part to form the oblique through holes. At this time, the part needs to be tilted with the help of drilling auxiliary tooling and clamped on the drilling machine with a vise to make the oblique through holes.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0029] like Figures 1 to 6 shown.

[0030] The present application discloses a drilling auxiliary tool for a multi-surface evenly distributed oblique through-hole component, comprising:

[0031] A basic force-bearing inclined block 1 is provided, wherein the inclined block 1 has a first clamping surface A11 and a first clamping surface B12, and the first clamping surface A11 and the first clamping surface B12 are opposite and parallel to each other, so that the vise can clamp and fix the inclined block on the drilling machine in one state for drilling; the inclined block 1 also has a second clamping surface A13 and a second clamping surface B14, and the second clamping surface A13 and the second clamping surface B14 are opposite and parallel to each other and perpendicular to the first clamping surface A11 and the first clamping surface B12, so that the vise can clamp and fix the inclined block 1 on the drilling machine in another state from the second clamping surface A13 and the second clamping surface B14 for drilling; the inclined block 1 has an inclined surface 16 which intersects with the first clamping surface A11 and the second clamping surface A13, and the inclined surface 16 of the inclined block 1 is provided with a regular quadrilateral diamond-shaped through hole 15.

[0032] The positioning column 3 that cooperates with the inclined block 1 includes: a diamond segment 31 that is a regular quadrilateral, and the diamond segment 31 can be quickly disassembled and slidably matched with the diamond through hole 15; a limiting segment 32 that is larger than the diamond through hole 15, and the limiting segment 32 is limitedly matched on the inclined surface 16 of the inclined block 1; a matching segment 33 that is a regular hexagon, and the regular hexagonal matching segment 33 can be slidably matched with the regular hexagonal through hole in the middle of the part 2. The diamond segment 31, the limiting segment 32, and the matching segment 33 are fixed and formed as one piece.

[0033] The drilling template 4 cooperates with the positioning column 3 to press the part 2, and the drilling template 4 is provided with a regular hexagonal pressing through hole 41 to slidably cooperate with the regular hexagonal matching section 33 of the positioning column 3. The force generated by the matching section 33 and the pressing through hole 41 is greater than the force generated by the matching of the diamond through hole 15 and the diamond segment 31. The different interference fit between the matching section 33 and the pressing through hole 41 and the interference fit between the diamond through hole 15 and the diamond segment 31 can be used to achieve different forces generated by the matching. By pulling the drilling template 4 with the part 2 and the positioning column 3, the positioning column 3 and the inclined block 1 are quickly slid out of engagement, so that the part 2 can be quickly repositioned and drilled on the inclined block 1, which solves the problem that slow rotation is required to release the threaded connection and the reversal cannot be achieved for the part to be quickly repositioned and drilled on the inclined base, thereby improving the processing efficiency of the parts.

[0034] The bottom of the outer side surface of the drilling template 4 is provided with a prying inclined surface 42 inclined toward the pressing through hole 41. The inclined surface 42 can form a prying opening with the part 2, through which an external pulling force is easily applied to the drilling template 4.

[0035] The drilling template 4 is provided with a guide hole 43 corresponding to the oblique through hole 21 of the part 2. The drill bit can drill the oblique through hole 21 of the part 2 by means of the guide hole 43. When drilling, the rhombus through hole 15 of the regular quadrilateral cooperates with the rhombus segment 31 of the regular quadrilateral to prevent rotation, and the regular hexagonal cooperation segment 33 cooperates with the regular hexagonal through hole in the middle of the part 2 to prevent rotation.

[0036] The present invention provides a method for drilling a multi-surface evenly distributed oblique through-hole component, comprising: using an auxiliary tool for drilling the multi-surface evenly distributed oblique through-hole component to quickly transpose the component 2 on the oblique block 1 and quickly drill the oblique through-holes on the multi-surfaces.

[0037] Specifically, the vise is fixed on the drilling machine by clamping the first clamping surface A11 and the first clamping surface B12 of the inclined block 1 or the second clamping surface A13 and the second clamping surface B14. The rhombus section 31 of the positioning column 3 is slidably matched with the rhombus through hole 15 of the inclined block 1. The limiting section 32 is limited on the inclined surface 16. The part 2 is slidably matched with the regular hexagonal matching section 33 of the positioning column 3 through the regular hexagonal through hole in the middle. The regular hexagonal pressing through hole 41 of the drilling template 4 is slidably matched with the matching section 33 of the positioning column 3. At this time, the force generated by the matching section 33 and the pressing through hole 41 is greater than that of the rhombus. The through hole 15 and the diamond segment 31 cooperate to generate the force, and the drilling template 4 presses the part 2 onto the inclined surface 16 of the inclined block 1; the drill bit drills the inclined through hole 21 on the part 2 through the guide hole 43 of the drilling template 4. When changing position, the drilling template 4, the part 2, and the positioning column 3 are quickly pulled out of the diamond through hole 15 of the inclined block 1 by prying the inclined surface 42, and then slid and disassembled for replacement, which solves the problem that slow rotation is required to release the threaded connection and the direction reversal cannot realize the rapid replacement drilling of the part on the inclined surface base. Then, the inclined through hole on the next surface of the part 2 is drilled, thereby improving the processing efficiency of the part.

[0038] The present application can also realize the displacement and disassembly drilling of the part 2 by only sliding and disassembling the drilling template 4 and the positioning column 3.
