Description

Floating cutter bar

Technical Field

The utility model relates to a machine adds the cutter field, concretely relates to cutter arbor floats.

Background

Along with the comprehensive popularization and use of 5G communication, the construction of 5G communication base stations is more and more, and the electrical components of the 5G communication base stations are usually arranged in an aluminum alloy shell, so that the aluminum alloy shell is formed by machining, most of molded surfaces on parts are directly milled on a blank surface, thicker burrs can be generated between the machined surface and the blank surface, and as the tolerance of the blank surface is larger, the numerical control machining must run a tool track according to the actual position of a numerical control program, so that the traditional tool cannot uniformly remove the burrs or chamfers under the condition of larger blank size deviation, and the existing floating tool has larger size and cannot machine narrow parts.

Disclosure of Invention

To the weak point among the above-mentioned prior art, the utility model provides a cutter arbor floats, its simple structure can realize milling cutter's processing of floating, along the application scope who has increased milling cutter.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a floating cutter bar is characterized in that: including handle of a knife, guide pin bushing, fixed cover, guiding axle, elastic component, plugging cover, wherein fixed cover has distributed assembly hole section, guiding hole section, screw hole section along the axis in proper order, the guide pin bushing tight fit set up in the assembly hole section, the guide pin bushing hole is coaxial with fixed cover, the one end sliding fit of handle of a knife set up in the guide pin bushing, guiding axle sliding fit set up in the guiding hole section, the guiding axle with handle of a knife coaxial coupling, the plugging cover set up in the screw hole section to it is rotatable, the elastic component sets up the guiding axle with between the plugging cover, the other end of handle of a knife has morse's taper hole.

Further, the guide hole section is a triangular hole, a square hole or a hexagonal hole.

Furthermore, the size of the guide part of the guide shaft is larger than the inner diameter of the guide sleeve.

Further, the elastic member is a spring.

Furthermore, the outer side end of the plugging cover is provided with an adjusting groove which is a straight groove or an inner hexagonal groove.

The beneficial effects of the utility model include: the floating machining is realized, the phenomenon that the local part of the workpiece is milled to be thin due to the fact that the sizes of the workpiece are inconsistent is avoided, the product percent of pass is improved, the floating machining method is suitable for feeding at narrow and small positions, and the machining efficiency is improved.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.

A floating cutter bar as shown in figures 1-2 comprises a cutter handle 1, a guide sleeve 2, a fixing sleeve 3, a guide shaft 4, an elastic piece 5 and a blocking cover 6, wherein an assembly hole section 7, a guide hole section 8 and a threaded hole section 9 are sequentially distributed on the fixing sleeve 3 along the axis. The guide sleeve 2 is tightly matched and arranged in the assembling hole section 7, an inner hole of the guide sleeve 2 is coaxial with the fixing sleeve 3, one end of the cutter handle 1 is arranged in the inner hole of the guide sleeve 2 in a sliding fit mode, the guide sleeve 2 is used for limiting the cutter handle 1, and the cutter handle is guaranteed not to shake in the floating process. The guide shaft 4 is arranged in the guide hole section 8 in a sliding fit mode, the guide hole section 8 is a regular polygonal hole such as a triangular hole, a square hole or a hexagonal hole, and the shape of the guide section in the middle of the guide shaft 4 is matched with that of the guide hole. The guide shaft 4 is coaxially connected with the tool shank 1, and limits the rotation of the tool shank 1 relative to the fixing sleeve 3, so that the tool shank 1 can only float axially. The size of the guide part of the guide shaft 4 is larger than the inner diameter of the guide sleeve 2. The tool handle 1 is connected with the guide shaft 4 and then cannot slide out, the guide shaft 4 is connected with the tool handle through left-handed threads, and the tool handle 1 is prevented from falling off during machining.

The plugging cover 6 is arranged in the threaded hole section 9 and can rotate, the elastic piece 5 is arranged between the guide shaft 4 and the plugging cover 6, and the elastic piece 5 is a spring. The outer side end of the plugging cover 6 is provided with an adjusting groove which is a straight groove or an inner hexagonal groove. The spring tension can be adjusted by rotating the plugging cover 6, so that the floating force of the knife handle can be adjusted.

In order to facilitate connection with a finished milling cutter, the other end of the cutter handle 1 in the embodiment is provided with a Morse taper hole. The milling cutter with the Morse taper can be directly inserted into the Morse taper hole for use, so that the disassembly and the assembly are very convenient.

The technical solutions provided by the embodiments of the present invention are introduced in detail, and the principles and embodiments of the present invention are explained by using specific examples, and the explanations of the above embodiments are only applicable to help understanding the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the description should not be construed as a limitation to the present invention.
