Abstract
The utility model relates to the field of hardware, and particularly to a milling cutter clamp. The keyway milling cutter clamp comprises the following components: a main shaft, a chuck, an index dial, a supporting frame, a base plate and a power device. The lower part of the main shaft is arranged in the supporting frame. The supporting frame is internally provided with a worm gear and a worm which is matched with the worm gear. The worm gear is arranged on the main shaft. The power device drives the main shaft to rotate through the worm gear and the worm. The supporting frame and the main shaft on the supporting frame are obliquely arranged on the base board. The index dial is arranged at the bottom of the chuck. The upper part of the main shaft passes through the index dial and is arranged in the chuck. The chuck is internally provided with a clamping opening for mounting the milling cutter. The clamping opening is provided above the main shaft. The milling cutter clamp can accurately convert angle without milling cutter removal and has the advantages of high convenience and high accuracy.
Description
Technical field
The utility model relates to the five metals field, relates in particular to a kind of milling fixture.
Background technology
Present milling cutter generally all is to make by machine cut, and milling cutter is very high for the requirement of size, so the required precision in working angles is very large.Milling cutter generally is fixed on the lathe by anchor clamps, but the main function of existing anchor clamps is that milling cutter is played fixation.After a knife face cutting of milling cutter is finished, milling cutter need be taken out, fix cutting after the indexing again.So, the angle of conversion is difficult to hold, and the degree of accuracy is not high.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of and will take out by milling cutter, just the milling fixture of the accurate indexing of energy.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of cotter mill cutter anchor clamps comprise main shaft, chuck, index dial, bracing frame, base plate and power set; The bottom of main shaft is arranged in the bracing frame, be provided with in the bracing frame worm gear and with the worm screw of its coupling, worm gear is installed on the main shaft, power set drive main shaft by worm and wheel and rotate; Bracing frame and on main shaft be obliquely installed on base plate; Index dial is installed in the bottom of chuck, and main shaft top is passed index dial and is installed in the chuck, is provided with the bayonet socket that milling cutter is installed in the chuck, and bayonet socket is in the top of main shaft.
As preferably, the angle between bracing frame and the base plate is 70 °.
The utility model adopts above technical scheme, and power set drive main shaft by worm and wheel and rotate, and main shaft top is arranged in the chuck, index dial is installed below the chuck, and index dial is being controlled the rotational angle of main shaft.During milling cutter, these anchor clamps will not take out by milling cutter in cutting, and accurate indexing just is very convenient and the degree of accuracy is high.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.
A kind of cotter mill cutter anchor clamps as shown in Figure 1 comprise main shaft 1, chuck 2, index dial 3, bracing frame 4, base plate 5 and power set.The bottom of main shaft 1 is arranged in the bracing frame 4, be provided with in the bracing frame 4 worm gear 41 and with the worm screw 42 of its coupling, worm gear 41 is installed on the main shaft 1, power set drive main shafts 1 by worm screw 42 and worm gear 41 and rotate, power set can be manual or automanual.Bracing frame 4 and on main shaft 1 be obliquely installed on base plate 5.Index dial 3 is installed in the bottom of chuck 2, and main shaft 1 top is passed index dial 3 and is installed in the chuck 2, is provided with the bayonet socket that milling cutter is installed in the chuck 2, and bayonet socket is in the top of main shaft 1.
As shown in the figure, milling cutter 6 is installed on the bayonet socket of chuck, milling cutter 6 is fixed by chuck and is linked to each other with main shaft.Angle between bracing frame 4 and the base plate 5 is 70 °, and at this moment, anchor clamps are used for 30 ° of end relief angles of keyseat milling cutter.Certainly, passable other angles that are suitable for of these anchor clamps are as the also end relief angle of 20 ° of millable slotting cutters behind the half-twist in the horizontal direction.
These anchor clamps will not take out by milling cutter after a knife face cutting of milling cutter is finished, and milling cutter just can rotate with main shaft, and index dial is being controlled the angle of rotating.So, indexing exactly just, very convenient and the degree of accuracy is high.
Claims (2)
1. cotter mill cutter anchor clamps is characterized in that comprising main shaft, chuck, index dial, bracing frame, base plate and power set; The bottom of main shaft is arranged in the bracing frame, be provided with in the bracing frame worm gear and with the worm screw of its coupling, worm gear is installed on the main shaft, power set drive main shaft by worm and wheel and rotate; Bracing frame and on main shaft be obliquely installed on base plate; Index dial is installed in the bottom of chuck, and main shaft top is passed index dial and is installed in the chuck, is provided with the bayonet socket that milling cutter is installed in the chuck, and bayonet socket is in the top of main shaft.
