Abstract
The utility model relates to a thin plate trepanning movable tool comprising a taper-shank and a cutter bar. A movable sleeve is sleeved on the taper-shank. The cutter bar passes through the movable sleeve through a second bolt and is fixed on the taper-tank shank. A long groove is milled in the cutter bar. A first cutter and a second cutter are inserted into and arranged on the two ends of the cutter bar. The first cutter is fixed on one end of the cutter bar through a first bolt in revolving and twisting mode. The second cutter is fixed on the other end of the cutter bar through a third bolt in revolving and twisting mode. A movable centre with orientating function is arranged on the lower end of the taper-shank. Degree scales are arranged on the taper-shank, the first cutter and the second cutter. The movable centre has an orientating function and the long groove which can be adjusted according to a bore diameter is arranged in the cutter bar. The cutter bar is capable of moving up and down on the taper-shank through the movable sleeve and processing various workpieces. Tool bits are arranged at both ends of the cutter bar, and therefore the work efficiency is improved. The thin plate trepanning movable tool has the advantages of being simple in structure, easy to manufacture and low in cost.
Description
Technical field
The utility model relates to a kind of cutter, specifically a kind of thin plate trepanning movable cutter.
Background technology
Cutter is the instrument that job shop often uses, but each cutter all can only be suitable for can not workpiece on, common cutter, process the aperture greater than 50mm at drilling machine, thickness is that the panel hole of 0.5～3mm is relatively more difficult, as adopt gas cutting, plate not only is out of shape, and the scum that is attached to around the hole must be cleared up, could process, and when processing different workpiece, need to change cutter, cumbersome, have plenty of and circular also being difficult to of cutting to accomplish, so just need a kind of cutter of stablizing and having several functions that guarantee to cut.
Summary of the invention
In order to address the above problem, the utility model provides a kind of stable cutter that guarantees to cut.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The utility model is a kind of thin plate trepanning movable cutter, comprise taper shank and knife bar, at the taper shank cover movable sleeve is arranged, knife bar passes described movable sleeve by the second screw and is fixed on the described taper shank, in knife bar, mill an elongated slot, insert respectively at the two ends of knife bar and to be provided with the first cutting knife and the second cutting knife, the first cutting knife screws on the end that is fixed on knife bar by the first screw, and the second cutting knife screws on the other end that is fixed on knife bar by the 3rd screw.
Further improvement of the utility model is: the lower end of taper shank is the centre with endlong movement of positioning action.
Further improvement of the utility model is: be provided with scale on taper shank, the first cutting knife and the second cutting knife.
The beneficial effects of the utility model are: trepanning cutter of the present utility model is by forming with the taper shank of centre with endlong movement and knife bar and cutting knife, centre with endlong movement plays the role of positioning, mill an elongated slot in the knife bar, can adjust according to pore size, knife bar can move up and down at taper shank by movable sleeve, can carry out the processing of various workpieces, the two ends of knife bar are provided with cutter head, increase work efficiency.
The utility model is simple in structure, and is easy to make, with low cost, can be used for processing sheet.
Description of drawings
Fig. 1 is structural representation of the present utility model.
