Background
In order to prevent the sharp corners of the end surfaces from being broken or swollen when the gears are meshed, which causes unnecessary troubles, the gear processing technology usually has a gear chamfering process. The gear chamfering needs to be carried out on the tip ends of tooth surfaces on two sides of a gear, at present, only one blade is generally arranged on a cutter bar of the gear chamfering machine, the gear chamfering with one angle can be processed, the gear generally needs to be chamfered on two sides, and then the turning-over clamping of a workpiece needs to be carried out in the processing process.
SUMMERY OF THE UTILITY MODEL
In view of the above situation, the utility model provides a turning tool for chamfering a gear, which solves the trouble of chamfering two sides of the original gear and improves the processing effect of chamfering the gear.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a gear chamfering uses turning cutter, includes cutter arbor and blade subassembly, the cutter arbor is including being used for toward the lathe on the cooperation press from both sides the connecting portion of dress and the installation department that is used for installing the blade subassembly, installation department and the coaxial rigid coupling of connecting portion, the installation department is kept away from the one end of connecting portion and has been seted up sword groove one, and sword groove two has been seted up at the middle part of installation department, the blade subassembly includes blade one, blade two, locking bolt one and locking bolt two, blade one is through locking bolt one fixed mounting in the sword groove one, blade two is through locking bolt two fixed mounting in the sword groove two.
Further, the connecting portion and the installation department of cutter arbor are cylindrical, and both integrated into one piece adopt a round steel processing to form.
Furthermore, the circumferential surface of the connecting part is provided with an anti-slip surface for preventing the rotating shaft of the connecting part, so that the condition that the rotating shaft slips at the joint of the cutter bar and the machine tool in the machining process is avoided.
Furthermore, the first cutter groove and the second cutter groove are respectively arranged on two opposite sides of the circumferential surface of the mounting part, the direction of the action surface of the first cutter blade is opposite to that of the action surface of the second cutter blade, and the cutting edge of the cutter blade is correspondingly designed according to the chamfering requirement of the gear to be machined.
The present invention also includes other components that enable its normal use, all by conventional means in the art, and in addition, devices or components not limited by the present invention, such as: the threaded connection between the locking bolt and the cutter bar and the like are all the prior art in the field.
The utility model has the following beneficial effects:
according to the turning tool for chamfering the gear, the two blades are integrated on one tool bar, double-sided chamfering of the gear workpiece can be realized without adjusting the directions of the workpiece and the blades, the operation steps of chamfering the gear are simplified, the labor intensity is reduced, and the machining efficiency is improved.
Drawings
FIG. 1 is a schematic structural view of a turning tool for chamfering a gear in an embodiment.
Fig. 2 is a schematic view of the working state of the turning tool for chamfering the gear in fig. 1.
Detailed Description
The technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments, and it should be understood that the described embodiments are only some embodiments, but not all embodiments, of the present invention.
Examples
As shown in figure 1, the turning tool for gear chamfering comprises a tool bar 1 and a blade assembly 2, wherein the tool bar comprises a connecting portion 1-1 and an installation portion 1-2, the connecting portion 1-1 is used for being matched and clamped on a machine tool, the installation portion is used for being fixedly connected with the connecting portion in a coaxial mode, a first tool groove 3 is formed in one end, away from the connecting portion, of the installation portion, a second tool groove 4 is formed in the middle of the installation portion, the blade assembly comprises a first blade 2-1, a second blade 2-2, a first locking bolt 2-3 and a second locking bolt 2-4, the first blade is fixedly installed in the first tool groove through the first locking bolt, and the second blade is fixedly installed in the second tool groove through the second locking bolt.
The connecting portion and the installation department of cutter arbor are cylindrically, and both integrated into one piece adopt a whole round steel processing preparation to form.
The circumferential surface of the connecting part is provided with an anti-slip surface 5 for preventing the rotating shaft of the connecting part, so that the condition that the rotating shaft slips at the joint of the cutter bar and the machine tool in the machining process is avoided.
The first cutter groove and the second cutter groove are respectively arranged on two opposite sides of the circumferential surface of the mounting part, and the direction of the action surface of the first blade is opposite to that of the action surface of the second blade.
As shown in fig. 2, during the machining process, the workpiece rotates, the tool bar also rotates, and the rotation axes of the tool bar and the tool bar are perpendicular to each other; after the blade finishes chamfering processing on one side of the tooth surface of the gear, the cutter rest drives the cutter bar to move to the other side of the workpiece, chamfering processing operation on the other side of the gear workpiece can be performed, even if the cutter bar is also suitable for the helical gear, workpiece turning or blade adjustment is not needed, operation time is greatly saved, and working efficiency is improved. According to the different gear chamfering surfaces of the workpiece to be machined, the cutting edge shapes of the first blade and the second blade are correspondingly matched with the chamfering requirements of the gear, the required chamfering shape can be cut at one time, the gear chamfering is more uniform and smooth, and the machining effect is improved.
The technical solution of the present invention is not limited to the above-described specific embodiments, and many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments, and any technical modifications within the spirit and principle of the present invention fall within the protection scope of the present invention.
