Description

Technical Field

[0001] The utility model relates to the technical field of steering gear housing processing, in particular to a tool for processing a steering gear housing to prevent deformation and breakage. Background Art

[0002] The steering gear is a machine that helps the driver to exert force when turning the steering wheel, so as to reduce the force required for the driver to steer, and achieve the purpose of making the driver relaxed and convenient when driving. The difficulty in processing the holes of the steering gear housing is that the hole wall has a 6.2-wide break that goes through the bottom. Most of the processing is done with a single-edged standard boring tool, but due to the poor rigidity of the steering gear housing, it is easy to cause trumpet holes, elliptical holes, etc., which seriously affects the subsequent assembly of the steering gear housing. Summary of the invention

[0003] The utility model aims to provide a tool for machining holes to prevent deformation of a steering gear housing with reasonable structure and high efficiency.

[0004] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a tool for anti-deformation and hole processing of a steering gear housing, which includes a tool body, one end of which gradually shrinks to form a connecting section, the end of the connecting section is concave to form a fastening screw hole, the other end of the tool body expands to form a torsion section, the end of the torsion section extends to form a hexagonal processing section, and a blade is installed at the end of the processing section. The blade has six pieces, which are respectively located at the corners of the hexagon of the processing section.

[0005] The hexagonal corners of the processing section are concave to form a blade groove, the blade is fixed in the blade groove, and the surface of the blade edge is raised from the surface of the processing section.

[0006] A stepped buffering position is provided between the processing section and the torsion section.

[0007] The end of the torsion section shrinks and then extends to form a processing section.

[0008] The connection between the blade body and the connection section is expanded to form a limiting ring, and the surface of the limiting ring is concave to form a ring groove.

[0009] After adopting the above scheme, the utility model supports the blade through the processing section, and then designs 6 blades. Under the effective support of the processing section, the blade will no longer be deformed after processing, thereby reducing the force on the product during processing and reducing the risk of product deformation. The structure after adopting this scheme is reasonable and the use effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION

[0011] The present invention is further described below in conjunction with all the accompanying drawings. The preferred embodiments of the present invention are as follows:

[0012] The embodiments described in this embodiment with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be understood as limiting this patent.

[0013] In the description of this patent, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing this patent and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this patent.

[0014] In the description of this patent, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, it can be fixedly connected or set, or it can be detachably connected or set, or connected or set in one piece. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0015] See attached Figure 1 The present embodiment describes a tool for processing a hole to prevent deformation of a steering gear housing, which includes a tool body 1. One end of the tool body 1 gradually contracts to form a connecting section 3. The connection between the tool body 1 and the connecting section 3 expands to form a limiting ring, and the limiting ring surface is concave to form a ring groove. The end of the connecting section 3 is concave to form a fastening screw hole 2. The other end of the tool body 1 expands to form a torsion section 4. The end of the torsion section 4 extends to form a hexagonal processing section 5. The processing section 5 is formed by the contraction and extension of the end of the torsion section 4. A stepped buffer position 6 is provided between the processing section 5 and the torsion section 4. A blade 7 is installed at the end of the processing section 5. The blade 7 is six pieces, which are respectively located at the hexagonal corners of the processing section 5. The hexagonal corners of the processing section 5 are concave to form a blade groove. The blade 7 is fixed in the blade groove, and the cutting edge surface of the blade 7 protrudes from the surface of the processing section 5.

[0016] After adopting the above scheme, the connecting section is used to connect with the external power, and then fixed by fastening screw holes after connection, so as to increase the integrity between the connecting section and the external components, and also prevent the cutter body from jumping during use. When the blade is processed, it will generate a large torque. When the torque is transmitted to the direction of the cutter body through the processing section, the torque section formed by expansion can resist most of the torque, so as to achieve the function of increasing the strength of the cutter body. The hexagonal processing section is adopted, that is, the blade can be supported. The cross section forms a gap between the inner wall of the working hole during processing. The gap can be ventilated to achieve a certain heat dissipation function. At the same time, when the blade is processed, the broken chips can enter the gap, and then be discharged from the gap upward from the hole. Compared with the traditional single-edged standard boring tool, the processing efficiency can be improved by more than 50%, and the structure is more reasonable, the use effect is good, and the strength is high.

[0017] The embodiments described above are only preferred embodiments of the present invention, and are not intended to limit the scope of implementation of the present invention. Therefore, all changes made based on the shape and principle of the present invention should be included in the protection scope of the present invention.
