Description
Technical Field
The utility model relates to an automobile parts processing technology field especially relates to a coaxial through-hole processing cutter.
Background
With the rapid development of the automobile industry and science and technology, automobiles become indispensable vehicles in people's daily life. As is well known, a front shackle structure of an automobile suspension is a device for mounting the automobile suspension to improve the mounting stability of the automobile suspension, and is widely used in the field of automobile parts. The existing front lifting lug structure of the automobile suspension is provided with a plurality of connecting arms, the end parts of the connecting arms are provided with coaxial connecting holes, the diameters of the connecting holes are the same, and the axial distance between the connecting holes is larger. In the prior art, a plurality of connecting holes are machined and machined respectively through multiple times of clamping, so that time and labor are wasted, the working efficiency is low, the coaxiality of the connecting holes is difficult to guarantee, and the quality of a workpiece is influenced.
Disclosure of Invention
An object of the utility model is to prior art not enough, and provide a coaxial through-hole machining cutter, its reasonable in design, convenient to use has solved among the prior art coaxial porous course of working, and work efficiency is low, the through-hole axiality is low, the relatively poor problem of work piece quality.
The utility model provides a technical scheme that its technical problem adopted is: the coaxial through hole machining tool comprises a tool bar, wherein a blade is arranged at the free end of the tool bar, a hoop is arranged at the fixed end of the tool bar, the hoop is rotatably connected with the tool bar, the outer surface of the hoop is smoothly arranged, and the distance between the hoop and the blade is equal to the distance between two adjacent through holes to be machined.
Specifically, an inner ball is arranged between the hoop and the cutter bar.
In particular, the axial width of the collar is smaller than the length of the through hole.
Specifically, the inserts include roughing inserts and finishing inserts.
Specifically, the outer wall of the hoop is in clearance fit with the inner wall of the machined through hole.
Specifically, the outer wall of the hoop is provided with outer rolling balls, and the outer rolling balls are in clearance fit with the inner wall of the machined through hole.
The utility model has the advantages that: the coaxial through hole machining tool comprises a tool bar, wherein a blade is arranged at the free end of the tool bar, a hoop is arranged at the fixed end of the tool bar, the hoop is rotatably connected with the tool bar, the outer surface of the hoop is smoothly arranged, and the distance between the hoop and the blade is equal to the distance between two adjacent through holes to be machined. Through set up the hoop at the cutter arbor tip, the support of the cutter arbor of being convenient for avoids because of the distance overlength, and the swing takes place for the free end of cutter arbor in the rotation process, influences the processing of through-hole. The utility model relates to a rationally, convenient to use improves work efficiency and product quality, guarantees that the product through-hole has higher axiality.

Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1, the coaxial through hole machining tool of the present embodiment includes a tool bar 1, a blade 2 is disposed at a free end of the tool bar 1, a hoop 3 is disposed at a fixed end of the tool bar 1, the hoop 3 is rotatably connected to the tool bar 1, an outer surface of the hoop 3 is smoothly disposed, a distance between the hoop 3 and the blade 2 is equal to a distance between two adjacent through holes to be machined, and an axial width of the hoop 3 is smaller than a length of the through hole. When the machining tool is used, a supporting component of the machine tool supports the hoop, the blade 2 of the tool firstly machines one connecting hole, after the first connecting hole of the blank workpiece is machined, the clamp of the blank workpiece and the machining tool move relatively, the hoop 3 moves to the machined through hole, the hoop 3 is supported by the first connecting hole, and the blade 2 of the tool machines the other connecting hole.
An inner ball is arranged between the hoop 3 and the cutter bar 1, so that the friction force between the hoop 3 and the cutter bar 1 is reduced, the hoop 3 is convenient to rotate, and the friction between the hoop 3 and the inner wall of the through hole is reduced.
The blade 2 comprises a rough machining blade 21 and a finish machining blade 22, one-time clamping can be completed, rough machining and finish machining of a through hole of a blank workpiece can be completed, and working efficiency is improved.
The clearance fit between 3 outer walls of hoop and the through-hole inner wall that has already been processed makes things convenient for hoop 3 to can regard first connecting hole as the support.
The outer wall of the hoop 3 is provided with outer rolling balls 4, and the outer rolling balls 4 are in clearance fit with the inner wall of the processed through hole, so that friction between the hoop 3 and the inner wall of the through hole can be reduced.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
