Abstract
The utility model relates to a nesting cutting tool through deep hole machining. The nesting cutting tool through the deep hole machining comprises a tool bit portion and a tool bar portion and is characterized in that the tool bit portion is in a pipe shape; the top of one end of the tool bit portion is uniformly provided with cutting edges along the circumference; internal threads are arranged in an end opening of the other end of the tool bit portion; scrap removal grooves are formed between the cutting edges of the tool bit portion; scrap accommodating grooves which are communicated with the scrap removal grooves are formed on the circumference of a pipe body of the tool bit portion; the front section of the tool bar portion is a circular pipe which has the same inner diameter with the tool bit portion; the rear section of the tool bar portion is a clamping section; and the end portion of the front section of the tool bar portion is provided with external threads which are matched with the internal threads which are arranged in the end opening of the tool bit portion. The nesting cutting tool through the deep hole machining has the advantages of enabling a short tool bit portion to be manufactured and being convenient to detach and perform cutter grinding due to the fact that the nesting cutting tool is manufactured into the detachable front section and the rear section; simultaneously solving the problem of scrap removal in the midway and being not easy to generate a blocking fault due to the fact that the scrap removal grooves and the scrap accommodating grooves are added; and reducing the production costs and significantly improving the productivity due to the fact that a long tool bar in the traditional machining way is omitted during usage.
Description
One, technical field
The utility model relates to a kind of jacking cutting tool of deep hole machining, belongs to cutter field in machining.
Two, background technology
Factory often has deep hole machining in carrying out the part machining process, and the core material in the middle of the hole will remain.Now to bore the long deep hole of 500mm as example, general operation is: do a metal long cutting tool bar, jacking cutting tool is welded in knife bar one end, hole.Its shortcoming is: during as the blade blunt of jacking cutting tool, before wanting at least 2 people to lift to abrasive machine, cutter is heavy, and two people coordinate difficulty, and grinding quality is difficult to guarantee.In addition, due to the long deep hole workpiece of 500mm, can not once complete drilling during boring, need to solve the chip removal problem midway.
Three, summary of the invention
The purpose of this utility model be to provide a kind of sharpening easily, chip removal jacking cutting tool smoothly.
The purpose of this utility model is achieved in the following ways:
The utility model comprises tool bit part and knife bar part, it is characterized in that: tool bit part is tubulose, the top of one end along circumference equal dividing be provided with blade, be provided with internal thread in the port of the other end, have chip area between the blade of tool bit part, be provided with the chip pocket with chip area UNICOM on the circumference of the pipe shaft of tool bit part; The leading portion of knife bar part is that internal diameter pipe body, the back segment identical with the tool bit part internal diameter are gripping section, and there is the external screw thread with tool bit part port internal thread coupling the end of the leading portion of knife bar part.
The utility model has the advantages that: jacking cutting tool is made two sections of the front and back that can dismantle, it is shorter that tool bit part can be made, and can dismantle easily sharpening, increase simultaneously chip area and chip pocket, solve chip removal problem midway, be difficult for producing " vexed car " phenomenon, and saved in use the metal long cutting tool bar in traditional processing mode, reduced production cost, productivity ratio significantly improves, labour intensity reduces, remarkable in economical benefits.
Four, description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 1.
The specific embodiment
With reference to accompanying drawing, the utility model comprises tool bit part and knife bar part, tool bit part is tubulose, the top of one end along circumference equal dividing be provided with blade 1, be provided with internal thread 4 in the port of the other end, have chip area 2 between the blade of tool bit part, be provided with the chip pocket 3 with chip area UNICOM on the circumference of the pipe shaft of tool bit part; The leading portion 5 of knife bar part is that the internal diameter pipe body identical with the tool bit part internal diameter, back segment 6 are gripping section, and there is the external screw thread with tool bit part port internal thread 4 couplings the end of the leading portion 5 of knife bar part.
During use, the gripping section of knife bar part is contained on rotated bed, the tool bit part with internal thread is tightened on external screw thread one end of knife bar part, holes after making up; When needing sharpening, screw off tool bit part, light sharpening.In boring procedure, chip area is constantly pushed the iron filings under boring in the chip pocket of back to, after the iron filings of chip pocket amass completely, retreats the boring jacking cutting tool, just is easy to discharge iron filings.
