Abstract
The utility model relates to a circular boring cutter head for milling. A center hole of the cutter head and an angle square milling head of machine tool accessories are accurately positioned and are connected by screw bolts. The utility model is characterized in that the cutter head is a circular boring cutter head, and the periphery of the cutter head is uniformly provided with a plurality of installation positions in central symmetry for rough and fine cutters. The circular boring cutter head can be respectively provided with a rough boring hole cutter, a half finish boring hole cutter and a finish boring hole cutter according to cutting conditions. The utility model has the advantages of favorable rigidity, favorable cutting stability, one tool with multipurpose, high utilization rate and high work efficiency.
Description
Technical field:
The utility model is relevant with planer-type milling machine, particularly a kind of circular bore hole cutterhead of planer-type milling machine.
Background technology:
The traditional bore hole cutterhead of planer-type milling machine as shown in Figure 1, be shoulder pole type cutterhead 2, blade row centre bore 21 is accurately located with machine tool accessories angle square milling head 1, and by bolt 4 connections, keyway 24 matches, and during lathe work, machine tool accessories angle square milling head 1 drives shoulder pole type cutterhead 2 and rotates, tool feeding is carried out the bore hole cutting.Because the stability and the rigidity of shoulder pole type cutter head structure are relatively poor, influence the bore hole precision, particularly the precision to the boring macropore is difficult to guarantee, its surface roughness only can reach Ra3.2, and from structure, to cutter select the shortage flexibility for use, operating efficiency also has improved necessity and may.
Summary of the invention:
The technical problems to be solved in the utility model is to overcome the defective of above-mentioned existing shoulder pole type cutterhead, provides the better dragon of a kind of stability and rigidity to mill circular bore hole cutterhead, improves bore hole precision and operating efficiency.
Technical solution of the present utility model is as follows:
A kind of dragon is milled circular bore hole cutterhead, the centre bore of cutterhead and machine tool accessories angle square milling head are accurately located, and, be characterized in that this cutterhead is circular bore hole cutterhead by Bolt Connection, offer a plurality of thick smart cutters installation site symmetrically equably in the circle center of this cutterhead.
The low diverse location in high back before described cutter installation site has on cutting direction.
But sharp knife is installed at the center, cutter installation site of described circular bore hole cutterhead symmetrically.
But wide sword boring cutter is installed at the center, cutter installation site of described circular bore hole cutterhead symmetrically.
But fine boring cutter is installed at the center, cutter installation site of described circular bore hole cutterhead symmetrically.
The cutter installation site of described circular bore hole cutterhead can be installed heavy boring cutter, half fine boring cutter and fine boring cutter simultaneously.
Technique effect of the present utility model:
A) on the structure cutterhead has been become circular beater plate by the shoulder pole shape,, the stability of continuous cutting has been increased because the quality of cutterhead is even.The rigidity of instrument and cutting was stable when the circular bore hole cutterhead of the utility model had solved bore hole, had improved machining accuracy, same support with this instrument after its roughness reach Ra1.6.
B) opened multiple thick, smart cutter installation site on the circumference of this cutterhead, can be according to the cutting situation respectively by dress heavy boring, half right boring and fine boring tool, and it is different on cutting direction the cutterhead position to be split into height, can be with participating in cutting simultaneously by putting before and after smatterer's tool, to form the characteristics of multistage cutting.Cutterhead both can be installed sharp knife, and wide sword boring cutter can be installed again, also fine boring cutter can be installed, and made the many usefulness of a kind of dedicated tool, and utilization rate improves, and cost descends.

The specific embodiment:
See also Fig. 2, Fig. 3 earlier, Fig. 2 and Fig. 3 are structural representation and the mounting structure cutaway views that the utility model dragon is milled circular bore hole cutterhead embodiment, as seen from the figure, the characteristics that the utility model dragon is milled circular bore hole cutterhead 3 are circular bore hole cutterheads, circle center at this cutterhead 3 offers six cutter installation sites 31 symmetrically equably, can utilize hold-down bolt 33 or wedge clamp 36 that pointed cutter 32, roughing tool 37 and finishing tool 34 are installed respectively, and finishing tool 34 also is provided with micro-adjusting mechanism 35, can finely tune the input of giving of finishing tool 34.
Centrosymmetric similar cutter installation site has the height difference, as preceding cutter among Fig. 3 32 and back cutter 32 ', can participate in cutting simultaneously, to form the characteristics of multistage cutting.
In the present embodiment, cutterhead can be installed heavy boring cutter 37, half fine boring tool 32 and fine boring tool 34 both can be installed sharp knife, and wide sword boring cutter also can be installed, also fine boring cutter can be installed, the utility model dragon is milled circular bore hole cutterhead, utilizes the centre bore 21 of cutterhead accurately to locate with machine tool accessories angle square milling head 1, and is connected by bolt 4, keyway 38 matches, and gets final product work.The utility model cutterhead has multiduty characteristics, and utilization rate improves, high efficiency, and cost descends.
