Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a forward reaming and reverse boring tool for processing a steering gear housing. Background Art

[0002] The steering system of a vehicle is composed of multiple components, among which the steering gear is one of the most core components. The steering gear requires a housing to protect the internal structure and support its operation. The housing is usually made of high-strength, corrosion-resistant metal materials. The steering gear housing is generally processed by deep hole processing, and a back boring compound tool is often used. The back boring compound tool is a special processing tool used to process parts with complex surfaces or surfaces that require multiple chamfers. It can also be used to process special structures such as deep holes and blind holes that are difficult to meet the requirements. Because it has the functions of boring and reaming at the same time, it meets a variety of processing needs. Therefore, multiple processes can be completed in one clamping, thereby improving production efficiency.

[0003] The existing back boring tool can only process a fixed deep hole at a time, which makes it inconvenient to adjust the diameter of the processed hole and the angle of the back taper. Therefore, the present application provides a forward-reaming back boring tool for steering housing processing to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a forward reaming back boring tool for machining a steering gear housing to solve the problem that the existing back boring tool can only machine a fixed deep hole at a time during machining, and it is inconvenient to adjust the diameter of the machined hole and the inverted cone angle.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] The tool holder is fixedly connected to the tool holder at one end and is provided with a sliding block, and the sliding block is slidably connected to the sliding block.

[0007] Preferably, a second tool head for fine machining is fixedly connected to the tool holder.

[0008] Preferably, the diameter of the second cutter head is larger than that of the first cutter head.

[0009] Preferably, the second cutter head is provided with a plurality of inclined surfaces.

[0010] Preferably, a limiting groove adapted to one end of the knife rod is opened inside the through groove on one side of the knife disc.

[0011] Preferably, the material of the tool rod is K cemented carbide.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] In the above scheme, by setting a tool holder, when working, the equipment rotates, and the first cutter head on the tool holder is driven to contact the workpiece to be processed and bore the hole. When the diameter of the hole to be processed needs to be adjusted, the tool rod is moved in the direction close to the limit groove. When the tool rod moves, the push block is driven to let the slider slide in the slide groove on the fixed block. The fixed block is pushed by the push block to move along the inclined side toward the outside of the cutter disc, driving the tool holder to move, so that the first cutter head and the second cutter head are pushed. The advantage of this is that the first cutter head can expand outward when boring, and the diameter of the hole to be processed can be freely adjusted. By setting the second cutter head, the second cutter head can perform fine processing on the hole, and when the tool holder moves, the second cutter head can adjust the taper angle of the hole with the help of the inclined surface, which is convenient for processing with different needs.
