The composite saw blade milling cutter
Technical field
The utility model relates to a kind of composite saw blade milling cutter, especially a kind of milling cutter for processing parts sidewall inside groove.
Background technology
The metal saw of traditional sense mainly contains knife bar, alignment pin, blade, pad, nut composition, is used for the processing of machining center and parts on lathe sidewall inside groove, can only process a groove at every turn.When the part sidewall had the two-layer inside groove in up and down, metal saw was wanted up and down milling twice, has wasted a large amount of time.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of composite saw blade milling cutter is provided, and uses this composite saw blade milling cutter can realize processing simultaneously two inside grooves, and efficient doubles.
According to the technical scheme that the utility model provides, described composite saw blade milling cutter comprises knife bar, it is characterized in that: at the end of described knife bar suit the first blade and the second blade, the first blade and the second blade are parallel to each other, and with cutter spindle to vertical setting; Be provided with the difference in height pad between described the first blade and the second blade.
Described the first blade and the second blade are fixed on knife bar by alignment pin.
At the arranged outside compress gasket of described the second blade, and lock by locking nut.
Composite saw blade milling cutter described in the utility model has solved the problem of the two-layer inside groove in processing up and down simultaneously with the Dual-layer blade, has improved production efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As shown in Figure 1: described composite saw blade milling cutter comprises knife bar 1, alignment pin 2, the first blade 3, difference in height pad 4, the second blade 5, compress gasket 6, locking nut 7 etc.
As shown in Figure 1, the utility model comprises knife bar 1, is set with the first blade 3 and the second blade 5, the first blades 3 and the second blade 5 in the end of knife bar 1 and is fixed on knife bar 1 by alignment pin 2; Described the first blade 3 and the second blade 5 are parallel to each other, and with the axial vertical setting of knife bar 1, be provided with the arranged outside compress gasket 6 of difference in height pad 4, the second blades 5 between the first blade 3 and the second blade 5, and by locking nut 7 lockings.
Operation principle of the present utility model and the course of work: the utility model is installed lower double-layer blades on knife bar 1, by the difference in height between difference in height pad 4 adjustment the first blades 3 and the second blade 5, two blades can be cut simultaneously, to realize the purpose of the two-layer inside groove in processing up and down simultaneously, improved widely production efficiency.
