Description

Technical Field

[0001] The utility model relates to a cutting tool, in particular to a novel motor housing boring tool. Background Art

[0002] At present, the boring tools on the market are mainly single-module boring tools, which are widely used in the field of hole processing of parts in holes. Generally, a boring tool can only bore once and can only bore holes of one size. As products become more and more complex and requirements become higher and higher, single-size boring tools cannot meet the needs of actual processing products, and cannot well ensure the circular coaxiality of multiple step holes.

[0003] The difficulty of machining motor housings is mainly reflected in the inner hole machining. With the diversification of product styles, there are single-aperture motor housings and multi-step direct motor housings. A traditional boring tool can only bore holes of one size. For multi-step motor housings, each step hole not only has requirements for hole diameter accuracy, but also has coaxiality requirements for the multi-step holes. If multiple boring tools are replaced to process multiple step holes of the same product, it is difficult to achieve the coaxiality requirements of the multi-step holes. No matter how good the equipment spindle itself is, there will be a slight error between tool changes, and the tool's own runout cannot be made consistent, resulting in cumulative errors, resulting in the coaxiality accuracy of the processed step holes cannot be guaranteed.

[0004] Therefore, developing a new type of motor housing boring cutter has become a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] The utility model aims to solve the above-mentioned shortcomings and provides a novel motor housing boring tool.

[0006] The above-mentioned purpose of the utility model is achieved through the following technical solutions: a new type of motor housing boring tool, including a connecting handle, which is connected to a tool body; at least two adjusting tool clamps are provided on the tool body and are locked and fixed by tool clamp locking screws; a tool clamp adjustment knob is provided on the adjusting tool clamp; and a blade placement groove is provided on each of the adjusting tool clamps, and a blade is installed.

[0007] Furthermore, the connecting handle is connected to the knife body via a screw.

[0008] Furthermore, the blade body is made of aluminum alloy.

[0009] Furthermore, the blade is locked in the blade placement slot of the adjusting tool holder by means of a screw.

[0010] Furthermore, a chip removal groove is provided on the cutter body on one side of the blade.

[0011] Furthermore, a weight-reducing groove is provided on the knife body.

[0012] The advantages of the utility model compared with the prior art are:

[0013] 1. High precision: The utility model realizes the effect of completing two-stage inner hole processing at one time, thereby ensuring the consistency of precision.

[0014] 2. High flexibility: The utility model can flexibly set the processing diameter, adjust the tool holder size according to different workpiece sizes, and achieve one-time forming. At the same time, different blade materials can be replaced according to the processing of different products to meet processing needs.

[0015] 3. Efficiency advantage: Traditional boring tools can only process one size at a time, while this new tool can process multiple sizes at one time, and the coaxiality between the steps is high.

[0016] 4. Processing cost advantage: The connecting handle adopts a detachable connection, and different connecting handles can be replaced according to different machine tools. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] like Figures 1 to 4 As shown, a new type of motor housing boring tool comprises a connecting handle 1, which is connected to a tool body 2 by a screw 11, so as to realize the high rigidity and replaceable flexibility of the boring tool; the tool body 2 is made of high-performance high-quality aluminum alloy. The tool body 2 is provided with a first adjusting tool clamp 3 and a second adjusting tool clamp 4, two adjusting tool clamps with different processing radius (in other embodiments, three or more adjusting tool clamps with different processing radius can also be provided), and is locked and fixed by a first tool clamp locking screw 9 and a second tool clamp locking screw 10; the first adjusting tool clamp 3 and the second adjusting tool clamp 4 are respectively provided with a first tool clamp adjusting knob 5 and a second tool clamp adjusting knob 6, which can adjust the processing diameter size according to the requirements of the product; the first adjusting tool clamp 3 and the second adjusting tool clamp 4 are both provided with a blade placement groove, and the first blade 7 and the second blade 8 for cutting the workpiece are installed by screw locking, and different blade materials can be replaced according to different requirements, and a chip removal groove 13 is provided on the tool body 2 on one side of the first blade 7 and the second blade 8.

[0023] In order to make the knife body light, a first weight-reducing groove 14 and a second weight-reducing groove 12 are provided on the knife body 2 .

[0024] Before assembly, clean the interface parts such as the connecting handle 1, the cutter body 2, the first adjustment tool clamp 3, the second adjustment tool clamp 4, the first blade 7 and the second blade 8; no dust, iron filings and other residues are allowed. Otherwise, the tool cannot be clamped effectively, the adjustment is not smooth enough, and even the mating surface is scratched. During assembly, first connect the connecting handle 1 and the cutter body 2 as a whole through the first screw 11 and the second screw 12, connect the first adjustment tool clamp 3 and the second adjustment tool clamp 4 to the cutter body 2 through the first tool clamp locking screw 9 and the second tool clamp locking screw 10, install the appropriate first blade 7 and the second blade 8 in the blade placement slot, and adjust the first tool clamp adjustment knob 5 and the second tool clamp adjustment knob 6 to the required size for processing. Before use, make sure that the tool is fully clamped and the mating surfaces fit tightly without gaps to obtain ideal axial runout.
