Background

The cyclone milling is a high-speed thread milling device matched with a common lathe. A thread machining method for milling thread from workpiece by using hard alloy forming cutter installed on high-speed rotary cutter head. Because the milling speed is high (the speed reaches 400m/min), the machining efficiency is high, and compressed air is adopted for chip removal and cooling. The cutting splash such as whirlwind in the processing process is called as whirlwind milling; the cyclone milling machine can realize dry cutting, heavy-load cutting, difficult-to-machine materials and ultrahigh-speed cutting, and has low power consumption. The surface roughness can reach Ra0.8 mu m. The lathe spindle has low rotating speed, so the lathe has high motion precision and good dynamic stability, and is an advanced thread machining method; the internal cutting type cyclone milling cutter disc wraps parts for cutting, and the cyclone milling cutter has the advantages of long wrapping stroke, large cutting amount, high cutting efficiency compared with external cutting cyclone milling, and high finish degree. Therefore, the internal cutting type whirlwind milling machine is suitable for thread precision machining.

The cutter head used by the existing cyclone milling machine can only repeatedly process the same position at the same time when processing a workpiece, and cannot process the workpiece with wider processing size at the same time, so that the working efficiency is low, the cutter needs larger processing depth when processing the same position, the processing pressure of the cutter is increased, the abrasion force of the cutter is also increased, and an angle staggered-tooth cutter head needs to be designed.

SUMMERY OF THE UTILITY MODEL

The utility model discloses solve prior art and can only process through a position, to the cell body of size broad, need the cutter to process many times, increased the machining pressure and the wearing and tearing of cutter, reduced machining efficiency, provide an angle side set blade disc for this.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides an angle side set blade disc, includes the blade disc body, the blade disc body is a cylinder blade disc, blade disc body surface evenly opens the sword groove that has a plurality of different degree of depth, the sword groove is the rectangular channel, there is the cutter through locking bolt fixed mounting in the sword groove, the cutter is through different degree of depth sword groove cutting depth difference formation dislocation offset an.

Furthermore, the cutter head body is located between the two cutter grooves and is provided with a weight reduction groove, two cutter locking holes are formed in two sides of the weight reduction groove, and a locking bolt is installed in each cutter locking hole.

Furthermore, the positions of the cutter locking hole on one side of the cutter groove and the cutter locking hole on the other side of the cutter groove correspond to the depth of the cutter groove, and the locking bolt penetrates through the cutter locking hole on one side and the cutter to be connected into the cutter locking hole on the other side in a threaded mode.

Further, the offset a is less than 1/2 cutter thickness.

Furthermore, a processing hole is formed in the center of the cutter disc, and the cutting edge end of the cutter faces the processing hole.

Compared with the prior art, the beneficial effects of the utility model are that: this device is through setting up the sword groove of the different degree of depth on the blade disc body, make the cutter of installing on the blade disc body form the cutting dislocation when processing, satisfy the work piece and can realize the processing of broad area through the cutter of dislocation tooth when processing, improve machining efficiency, processing, the degree of depth of cutter quantity 1 to n and dislocation offset an is confirmed to the size of processing as required, after the cutter is installed in the cutter disc body corresponds sword inslot, cutting process begins promptly, the work piece is progressively processed No. n cutter through No. 1 cutter, make the machining allowance progressively amputated, the machining pressure of cutter has been reduced, thereby reduce the cutter loss.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention;

fig. 2 is a front view of an embodiment of the present invention;

fig. 3 is a schematic diagram of a misalignment offset a in an embodiment of the present invention;

the most important element symbols of the embodiment of the utility model are as follows:

the cutter comprises a cutter head body-1, a weight reduction groove-101, a cutter locking hole-102, a machining hole-103, a cutter groove-2, a cutter-3 and a dislocation offset a-4.

Detailed Description

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

As shown in fig. 1 to 3, an angle staggered tooth blade disc, including blade disc body 1, blade disc body 1 is a cylinder blade disc, blade groove 2 that has a plurality of different degree of depth is evenly opened on blade disc body 1 surface, blade groove 2 is the rectangular channel, there is cutter 3 through locking bolt fixed mounting in blade groove 2, cutter 3 cuts out the depth difference through different degree of depth blade groove 2 and forms dislocation offset a 4.
