Background
The turning tool is a tool used for turning and provided with a cutting part, the turning tool is one of the most widely used tools in the cutting and processing, and the working part of the turning tool is a part for generating and processing chips and comprises a cutting edge, a structure for breaking or rolling up the chips, a space for discharging or storing the chips, a channel of cutting fluid and other structural elements.
The existing turning tool is generally formed by welding a cutter bar, a cutter head and a blade together, the cutter head is easy to wear in the using process, the cutter bar is scrapped after the cutter head is worn, the use cost is high, and the machining efficiency can be influenced by frequently replacing the cutter.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to provide a turning tool with a replaceable tool bit, which solves the problems of the prior art.
The purpose of the utility model is realized by adopting the following technical scheme:
the utility model provides a lathe tool of removable tool bit, includes tool bit and cutter arbor, the tool bit with the connection can be dismantled to the cutter arbor, the tool bit is cylindrical, the welding of tool bit front end has the cutting edge, the spread groove has been seted up to cutter arbor one end, the size of spread groove with the size phase-match of tool bit, the tool bit inserts the up end of spread groove internal portion is the plane.
Preferably, a plurality of countersunk holes are formed in the top end of the cutter bar corresponding to the connecting end surface of the cutter head.
Preferably, there are two counter bores, and a first bolt and a second bolt are arranged in the two counter bores.
Preferably, the first bolt and the second bolt are both hexagon socket head bolts.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model has the advantages of reasonable and simple structure design, the tool bit and the cutter bar adopt split type design, the cutter wear makes only need to change the tool bit can, the service efficiency of the cutter bar is improved, and the cost is greatly saved; meanwhile, only two bolts need to be disassembled and assembled when the tool bit is replaced, so that the time for replacing the tool is greatly saved, and the machining efficiency is improved.

Detailed Description
The invention will be further described with reference to the following drawings and detailed description:
in the description of the present invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
As shown in fig. 1-5, a turning tool with a replaceable tool bit comprises a tool bit 1 and a tool bar 2, wherein the tool bit 1 is detachably connected with the tool bar 2, the tool bit 1 is cylindrical, a cutting edge 3 is welded at the front end of the tool bit 1, a connecting groove 4 is formed in one end of the tool bar 2, the size of the connecting groove 4 is matched with that of the tool bit 1, and the tool bit 1 is inserted into the upper end face of the inner part of the connecting groove 4.
The top end of the cutter bar 2 corresponding to the connecting end face of the cutter head 1 is provided with a plurality of countersunk holes 5.
Further, there are two counter bores 5, and a first bolt 6 and a second bolt 7 are arranged in the two counter bores 5.
During operation, tool bit 1 is in the same place through first bolt 6 and second bolt 7 and cutter arbor 2 fastening connection, and the lathe tool carries out cutting process back, and cutting edge 3 takes place wearing and tearing, unscrews first bolt 6 and second bolt 7, takes out tool bit 1 that tool bit 1 changed newly, carries out cutting process again after screwing up first bolt 6 and second bolt 7.
In particular, the upper end surface of the part of the cutter head 1 inserted into the connecting groove 4 is a plane, so that the bolt can be used for fastening and connecting the cutter head 1 and the cutter bar 2 better.
Specifically, the first bolt 6 and the second bolt 7 are both hexagon cylindrical head bolts.
The utility model has the advantages of reasonable and simple structure design, the tool bit 1 and the tool bar 2 adopt split type design, the tool bit 1 only needs to be replaced when the tool is worn, the use efficiency of the tool bar 2 is improved, and the cost is greatly saved; meanwhile, only two bolts need to be disassembled and assembled when the tool bit 1 is replaced, so that the time for replacing the tool is greatly saved, and the machining efficiency is improved.
Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
