Abstract
The utility model discloses a tool box for milling the front surface of a cylinder cover of an engine, comprising a tool body. A blade is welded on the tool body and comprises a hard alloy layer; a cutting layer is arranged on the hard alloy layer in a fixed connection manner; and a mounting through hole is arranged on the tool body. A chamfered edge is arranged at an edge of the cutting layer, and an included angle between the chamfered edge and the horizontal surface is 20 degrees. In the tool box, the structure is simple, and the use is convenient. Since the mounting through hole is arranged on the tool body, the installation and the positioning are very convenient. After the chamfered edge is additionally arranged, the strength of the edge is improved, and the edge is not easily broken when the tool box is in working, so that the service life of the tool body is greatly prolonged. In short, in the tool box, the cutting efficiency is improved, the service life of the tool is prolonged, and the machining accuracy of a workpiece is improved, so that the production cost of enterprises is reduced, the quality of products of the enterprises is improved, and higher economic benefit is created for the enterprises.
Description
Technical field
The utility model relates to a kind of cutter, especially a kind of cutter casket that is used to mill the engine cylinder cover front.
Background technology
The existing cutter casket that is used to mill the engine cylinder cover front comprises cutter hub, welding is provided with blade on the cutter hub, blade is formed through the HTHP compacting by cutting lay (material of cutting lay is polycrystalline diamond or polycrystalline cubic boron nitride) and hard alloy layer, and the shape of cutting lay and hard alloy layer is all fan-shaped.The edge strength of this cutter casket is lower, quick abrasion when work, and easy tipping, service life is shorter.
The utility model content
The purpose of this utility model be to provide a kind of intensity higher, be difficult for the long cutter casket that is used to mill the engine cylinder cover front of tipping, service life.
For achieving the above object, the cutter casket that is used to mill the engine cylinder cover front of the present utility model comprises cutter hub, and welding is provided with blade on the cutter hub, and blade comprises hard alloy layer, the fixedly connected cutting lay that is provided with on the hard alloy layer, and described cutter hub is provided with the installation through hole.
The blade place of described cutting lay is provided with chamfered edge, and the angle of described chamfered edge and horizontal plane is 20
。
The utility model is simple in structure, and is easy to use.Cutter hub is provided with the installation through hole, very is convenient to install the location.After setting up chamfered edge, the intensity of blade is improved, and is difficult for tipping during work, and prolong the service life of cutter greatly.In a word, the utility model can promote stock-removing efficiency, prolongs the service life of cutter, improve the machining accuracy of workpiece, thereby reduces the production cost of enterprise, promotes the quality of enterprise product, for enterprise creates higher economic benefit.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the enlarged drawing at A place among Fig. 1.
The specific embodiment
As shown in Figure 1 to Figure 3, the cutter casket that is used to mill the engine cylinder cover front of the present utility model comprises cutter hub 1, welding is provided with blade on the cutter hub 1, blade comprises hard alloy layer 2, by the fixedly connected cutting lay 3 that is provided with of method of HTHP compacting, the material of cutting lay 3 is polycrystalline diamond (PCD) composite sheet on the hard alloy layer 2.The blade place of described cutting lay 3 is provided with chamfered edge 4, and described chamfered edge 4 is 20 with the angle α of horizontal plane
。For ease of installing, also be provided with on the described cutter hub 1 through hole 5 is installed.Wherein, the shape of cutting lay 3 and hard alloy layer 2 is all fan-shaped.
After setting up chamfered edge 4, the intensity of blade is improved, and is difficult for tipping during work, and prolong the service life of cutter greatly.In a word, the utility model can promote stock-removing efficiency, prolongs the service life of cutter, improve the machining accuracy of workpiece, thereby reduces the production cost of enterprise, promotes the quality of enterprise product, for enterprise creates higher economic benefit.
Certainly, the utility model includes but not limited to present embodiment, also can adopt polycrystalline cubic boron nitride (PCBN) composite sheet as the material of cutting lay 3, or the like; This type of conversion all drops within the protection domain of the present utility model.
