Description
Technical Field
The utility model relates to a lathe processing technique especially relates to a two-sided for beveler tool bit.
Background
Traditional lathe processing is that the work piece is rotatory, to the less part of single-piece process time, just needs the main shaft to frequently open and stop, and machining efficiency is not high, so has appeared that a batch of work pieces are static, the rotatory professional equipment of cutter. For some pure bar chamfering machining, the machining efficiency is high. However, when different chamfers are machined, different tool bits need to be replaced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problem that different tool bits need to be changed to the different chamfers of traditional work piece processing, provide a tool bit for double-sided chamfering machine, this tool bit can be fast the interval of two knife rests of accurate adjustment, and then the distance of accurate adjustment ceramic tool bit apart from the work piece, realize the accurate adjustment to work piece cutting radius.
In order to achieve the above object, the utility model adopts the following technical scheme: a kind of two-sided chamfering machine tool bit includes: drive shaft, ceramic tool bit and two sets of tool holder, two sets of tool holder set up relatively on circular table surface, tool holder includes movable tool post, screw rod end headstock, trapezoidal lead screw, trapezoidal nut and bevel gear, movable tool post bottom is fixed on trapezoidal nut, trapezoidal nut and trapezoidal lead screw thread fit, the one end that trapezoidal lead screw is close to the table surface centre of a circle is provided with the bevel gear, and the other end is provided with screw rod end headstock, the bevel gear meshes with the drive shaft, ceramic tool bit is fixed at movable tool post top.
Further, a cutter head shell is arranged on the upper cover of the circular working table surface, and the ceramic cutter head is located above the cutter head shell.
Further, the ceramic tool bit is arranged on one side, close to the circle center of the circular workbench, of the movable tool rest.
Further, a bearing is arranged between the driving shaft and the circular working table surface.
Further, the end head seat of the fixed screw rod below the trapezoidal nut is arranged at the outer edge of the circular workbench surface.
The utility model discloses double-sided for beveler tool bit theory of operation: when the distance between the two tool rests needs to be adjusted, only the driving shaft needs to be controlled to rotate, the trapezoidal screw rod is driven to rotate through the bevel gear, and the trapezoidal nut is pushed by the trapezoidal screw rod to move back and forth, so that the cutting radius can be accurately adjusted. And trapezoidal thread has the characteristics of auto-lock, can guarantee in cutting process, does not have extra power to conduct on the drive shaft.
The utility model discloses double-sided chamfering machine tool bit simple structure, reasonable, compact, the interval of two knife rests of adjustment that can be accurate fast, and then the accurate adjustment pottery tool bit is apart from the distance of work piece, realizes the accurate adjustment to work piece cutting radius.

Detailed Description
The invention is further illustrated below with reference to the following examples:
example 1
The embodiment discloses a cutter head for a double-sided chamfering machine, as shown in fig. 1 to 3, comprising: drive shaft 7, ceramic tool bit 1 and two sets of cutter support, circular table surface upper shield is equipped with tool bit casing 8, ceramic tool bit 1 is located tool bit casing 8 top, two sets of cutter support are located tool bit casing 8 below.
Two sets of tool supports set up relatively on circular table surface, tool support is including movable tool rest 2, screw rod end headstock 3, trapezoidal lead screw 4, trapezoidal nut 5 and bevel gear 6, movable tool rest 2 bottoms are fixed on trapezoidal nut 5, trapezoidal nut 5 and trapezoidal lead screw 4 screw-thread fit, trapezoidal lead screw 4 is provided with bevel gear 6 near the one end in the table surface centre of a circle, and the other end is provided with screw rod end headstock 3, screw rod end headstock 3 sets up in circular table surface off-edge department. The bevel gear 6 is meshed with a bevel gear (bevel gear) at the top of the driving shaft 7, and a bearing is arranged between the driving shaft 7 and the circular working table. The ceramic tool bit 1 is arranged on one side, close to the circle center of the circular workbench, of the movable tool rest 2.
The working principle of the tool bit for the double-sided chamfering machine is as follows: when the distance between the two tool rests needs to be adjusted, only the driving shaft 7 needs to be controlled to rotate, the trapezoidal lead screw 4 is driven to rotate through the bevel gear, and the trapezoidal nut 5 is pushed by the trapezoidal lead screw to move back and forth, so that the cutting radius can be accurately adjusted. And trapezoidal thread has the characteristics of auto-lock, can guarantee in cutting process, does not have extra power to conduct on drive shaft 7.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
