Description
Technical field
The utility model relates to cutter field, particularly relates to a kind of brill cutter cutter with fraising function.
Background technology
Cutter is very common in field of machining, especially in boring, fraising process, has just accounted for 1/3rd operation nearly.Such as the aperture fine finishining of picture rice transplanter accessory, often need the first operation afterwards of two cutters, so just greatly reduce operating efficiency, so need to reequip a kind of cutter, make the fine finishining in aperture to carry out simultaneously, so just can greatly improve production output, reduce costs.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of brill cutter cutter with fraising function, simple in structure, have cutter head in the cloth postpone of knife rest middle part, this rear blade can carry out fine finishining to aperture together in conjunction with the front cutter head of knife rest front end simultaneously, has greatly improved operating efficiency.
The utility model solves the technical scheme that its technical problem adopts: a kind of brill cutter cutter with fraising function is provided, comprise handle of a knife, knife rest and front cutter head, described handle of a knife one end is connected with the rotating shaft of lathe, the other end is connected with knife rest, described knife rest is screw type, the front end of described knife rest, be furnished with front cutter head with tool axis position overlapping position, the rear end of described front cutter head is furnished with two rear blades about tool axis symmetry.
As a kind of optimal way of brill cutter cutter described in the utility model, the surface of described rear blade is concaved circular cambered surface in quadrangle, is applicable to the carrying out of fraising.
Supplement as the one of brill cutter cutter described in the utility model, the wherein both sides of described rear blade are adjacent with the first groove surface, the second groove surface respectively.
Another kind as brill cutter cutter described in the utility model supplements, and described rear blade becomes 120～150 ° of angles with tool axis.
Supplement as also having of brill cutter cutter described in the utility model is a kind of, the vertical range that described rear blade departs from tool axis is greater than the vertical range that front cutter head departs from tool axis, and fraising and boring are carried out simultaneously, has improved operating efficiency.
As the another kind of optimal way of brill cutter cutter described in the utility model, described front cutter head and the horizontal range of rear blade are 10～12mm, prevent interfering with each other of drilling and reaming, further increase work efficiency.
beneficial effect
The utility model relates to a kind of brill cutter cutter with fraising function, simple in structure, has cutter head in the cloth postpone of knife rest middle part, and this rear blade can carry out fine finishining to aperture together in conjunction with the front cutter head of knife rest front end simultaneously, has greatly improved operating efficiency.
Brief description of the drawings
Fig. 1 is main TV structure figure of the present utility model;
Fig. 2 is knife rest part enlarged drawing of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1-2, embodiment of the present utility model relates to a kind of brill cutter cutter with fraising function, comprise handle of a knife 1, knife rest 2 and front cutter head 3, described handle of a knife 1 one end is connected with the rotating shaft of lathe, the other end is connected with knife rest 2, described knife rest 2 is screw type, the front end of described knife rest 2, is furnished with front cutter head 3 with tool axis position overlapping position, and the rear end of described front cutter head 3 is furnished with two rear blades 4 about tool axis symmetry.
The surface of described rear blade 4 is concaved circular cambered surface in quadrangle.
The wherein both sides of described rear blade 4 are adjacent with the first groove surface 41, the second groove surface 42 respectively.
Described rear blade 4 becomes 120～150 ° of angles with tool axis.
The vertical range that described rear blade 4 departs from tool axis is greater than the vertical range that front cutter head 3 departs from tool axis.
Described front cutter head 3 is 10～12mm with the horizontal range of rear blade 4.
Embodiment
The knife rest 2 of this brill cutter cutter is screw type, cutter head 3 before the front end of knife rest 2 is furnished with, the rear end of described front cutter head 3 is furnished with two rear blades 4, and workpiece is being added to man-hour, the boring that front cutter head 3 is responsible for workpiece, and the fraising that rear blade 4 is responsible for workpiece, both are carried out simultaneously, greatly saved the working time, improved operating efficiency, also reduce workman's labour intensity, and then reduced the cost that company drops into.Compare before technological improvement, this brill cutter cutter one month can be than more than 80 product of original many production.
