Description
Technical Field
The invention belongs to the technical field of machining, relates to a turning tool seat, and particularly relates to a double-tool-position excircle turning tool seat.
Background
The excircle characteristic is the most common processing characteristic in machine parts, and a typical processing method is to clamp a part to be processed on a machine tool chuck, clamp an excircle turning tool on an excircle turning tool seat, connect the excircle turning tool seat on a machine tool rest, and move the part to be processed by the excircle turning tool clamped on the excircle turning tool seat according to a preset track so as to carry out cutting processing.
In the actual machining process, the traditional excircle machining method has two disadvantages: on one hand, the excircle processing cutting parameters are limited by the service life of the cutter, and the overlarge cutting parameters can generate a large amount of cutting heat and cutting force in the processing process, so that the service life of the cutter is seriously reduced, and meanwhile, the back cutting amount of excircle processing is small, and the processing efficiency is also limited; on the other hand, for the excircle turning with large back bite, the excircle diameter is reduced after the part is processed, the rigidity is poor, and the part is seriously bent and deformed. In the prior art, some high-end numerical control equipment has a double-tool-rest mechanism, but the equipment cost is too high, the economical efficiency and the universality are poor, and two external turning tools cannot be simultaneously machined only by a single-tool-rest machine tool.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides the double-tool-position excircle turning tool holder, which prevents parts from deforming, reduces the back tool consumption and improves the machining efficiency when only a single-tool-holder machine tool excircle is turned.
In order to achieve the purpose, the invention adopts the technical scheme that:
a double-tool-position excircle turning tool holder is arranged on a tool rest of a machine tool and used for clamping an excircle turning tool. The double-cutter-position excircle turning tool holder comprises a tool holder 1 and an adjusting bolt 2.
The side of the tool apron 1 is provided with a groove 3, the center of the groove 3 is provided with a through hole 4, the aperture of the through hole 4 is larger than the diameter of a part after excircle processing, and the part after excircle processing can pass through the through hole 4. The groove 3 below the center of the through hole 4 is provided with a zero scale point, and scales are marked at two ends of the groove 3 along the length direction of the tool apron 1.
Threaded holes 5 are respectively and symmetrically arranged on the tool apron 1 at the top and the bottom of the groove 3, and the adjusting bolt 2 penetrates through the threaded holes 5 through threaded fit so as to press the tool.
The threaded holes 5 and the adjusting bolts 2 with different quantities are arranged according to the length of the external turning tool so as to fix the external turning tool.
In the recess 3 of blade holder 1, can once only the clamping two excircle lathe tools, two excircle lathe tool knife tips are installed relatively, and central symmetry installs in through-hole 4 central both sides to it is fixed through adjusting bolt 2. The positions of the two external turning tools in the groove of the tool apron can be adjusted according to the external circle size of the part to be processed and by referring to the scales on the tool apron.
The invention can also be used as a common single-tool excircle turning tool seat.
The invention has the beneficial effects that: the double-cutter-position excircle lathe cutter seat is simple in structure and good in economical efficiency; by clamping two external turning tools at one time, the processing deformation of parts is effectively reduced, and the effect of improving the processing efficiency is obvious; meanwhile, the tool can be used as a single tool rest, and the universality is good.

Detailed Description
The following detailed description of the present invention, taken in conjunction with the accompanying drawings, will provide those skilled in the art with a more complete and thorough understanding of the present invention.
As shown in figure 1, the double-tool-position excircle turning tool apron comprises a tool apron 1 and an adjusting bolt 2. The side of the tool apron 1 is provided with a groove 3, the center of the groove 3 is provided with a through hole 4, the aperture of the through hole 4 is larger than the diameter of a part after excircle processing, and the part can pass through the through hole 4 after excircle processing. The groove 3 below the center of the through hole 4 is provided with a zero scale point, and scales are marked at two ends of the groove 3 along the length direction of the tool apron 1.
Three threaded holes 5 are respectively and symmetrically arranged on the tool apron 1 at the top and the bottom of the groove 3, and the adjusting bolt 2 penetrates through the threaded holes 5 through threaded fit so as to press the tool.
Before turning, pack into the recess 3 of blade holder 1 respectively with a left hand excircle lathe tool and a right hand excircle lathe tool, according to treating the processing part excircle size, refer to the scale mark on the blade holder recess and fix a position two excircle lathe tools, screw in threaded hole 5 on the blade holder 1 with adjusting bolt 2, screw up adjusting bolt 2 and make two lathe tool rigidity, install adjusted blade holder 1 on the lathe tool rest. During turning, a part to be machined rotates along with a main shaft of a machine tool, the center of a through hole 4 in a groove of a tool apron is aligned with the rotation center of the part to be machined, a cutter on the tool apron 1 moves along with a tool rest of the machine tool according to a preset track, and the machined part penetrates through the through hole 4 in the groove 3 of the tool apron 1.
As shown in fig. 2, the double-tool-position excircle lathe tool holder of the present invention can also be used for a common single-tool excircle lathe tool holder by adjusting the clamping position of the lathe tool holder relative to the tool holder of the machine tool.
The present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit and scope of the present invention by those skilled in the art.
