AI Technical Summary
In the existing technology, drilling the machine head and tool holder housing is slow, inefficient, and has large errors, with the error increasing due to multiple positioning steps.
The tooling uses a combination of positioning base, positioning protrusion and positioning bolt. It is positioned on two axes and two sides. The positioning protrusion matches the first through hole and the positioning bolt matches the second through hole to achieve one-time positioning of the machine head tool holder shell. Combined with the blind groove and avoidance groove design, it avoids wear on the threaded part and performs fine machining.
It improves the machining quality and efficiency of the machine head tool holder housing, reduces errors, and protects the quality of the machine head tool holder housing.

[0026] Reference Figure 1-5 ,
[0027] A tool holder housing fixture includes: a positioning base 2, a positioning protrusion 3, and a positioning bolt 4. A first through hole 11 and a second through hole 12 are formed on the tool holder housing; the second through hole 12 is a countersunk hole; the positioning protrusion 3 is disposed on the positioning base 2, and the positioning protrusion 3 matches the first through hole 11; the positioning bolt 4 matches the second through hole 12; the positioning bolt 4 presses against the countersunk hole; the bottom surface of the tool holder housing 1 abuts against the positioning base 2.
[0028] By adopting the above technical solution, the machine head tool holder housing 1 is positioned using a two-axis, two-surface method. One of the surfaces is provided by bolts, thus exposing most of the outer surface of the machine head tool holder housing 1. During machining of the machine head tool holder housing 1, it is possible to achieve single-positioning and machine most of the machine head tool holder housing 1, thereby avoiding the increased errors that can easily occur with multiple positioning and greatly improving the machining quality.
[0029] Specifically, a blind groove 21 is formed on the positioning base 2, and the positioning protrusion 3 is disposed in the blind groove 21. Thus, the positioning protrusion 3 and the positioning base 2 are detachably connected, and the part of the positioning protrusion 3 connected to the positioning base 2 is located below the contact surface between the positioning base 2 and the machine head tool holder housing 1. Therefore, there is no connecting part between the positioning protrusion 3 and the positioning base 2, thereby improving the positioning effect of the machine head tool holder housing 1.
[0030] Specifically, a clearance groove 22 is formed on the positioning base 2, and part of the machine head tool holder housing 1 is located in the clearance groove 22.
[0031] Specifically, the positioning bolt 4 includes a smooth rod portion and a threaded portion; the threaded portion is connected to the positioning base 2; the cross-section of the threaded portion is smaller than the cross-section of the smooth rod portion, and the smooth rod portion matches the second through hole 12. This avoids the threaded portion rotating relative to the second through hole 12 during the process of screwing the threaded portion into the positioning base 2, and the situation where contact with the inner wall of the second through hole 12 easily causes wear on the inner wall of the second through hole 12, thus better protecting the quality of the machine head tool holder housing 1.
[0032] Specifically, a blind hole 13 is formed on the machine head tool holder housing 1, the axis of which matches the axis of the first through hole 11; the diameter of the blind hole 13 is larger than the diameter of the first through hole 11; the height of the positioning protrusion 3 is smaller than the length of the first through hole 11. Both the first through hole 11 and the second through hole 12 are rough-machined holes; when the machine head tool holder housing 1 is placed on the positioning base 2, the blind hole 13 is precision-machined.
[0033] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
