Abstract
The utility model discloses a kind of accurate alley cutter, comprise cutter head and cutter hub, cutter head adopts carbide alloy to make, cutter hub adopts steel alloy to make, be welded and fixed between cutter head with cutter hub and be connected, solder side is plane-welding, and cutter hub is provided with tool-holder and behave affectedly body, and the inner wall surface clamping cavity is provided with screw thread.Adopt the accurate alley cutter of the utility model to reduce the cost of charp tool, installation way is solid and reliable, and repetitive positioning accuracy is high, and can realize DRY CUTTING, reduces environmental pollution, is particularly suitable for being used as star-wheel processing milling cutter.
Description
Technical field
The utility model relates to automobile manufacturing field, the accurate alley cutter of specifically a kind of truck drive shaft star-wheel processing.
Background technology
At present, the constant velocity cardan joint that car transmission shaft is conventional is rzeppa joint, and be one of core component of automobile, its effect is delivered to two wheels from speed changer by the power of engine.These parts are also the safety members on automobile, and the star-wheel of its inside is one of vitals in this universal joint, and the precision of star-wheel directly affects the quality of whole power transmission shaft, can cause power transmission shaft abnormal sound and power transmission shaft premature failure.The automobile industry high speed development of this Ji Nian China, star-wheel demand is huge, so the production efficiency of manufacturing enterprise and cost are most important again, embodying on cutter is exactly high accuracy, high efficiency.All the time, the processing of star-wheel mainly contains broaching and indexable insert tip, throw away tip milling two kinds of processing modes.Broaching efficiency is low, and not environmentally; And indexable insert tip, throw away tip machining accuracy is low, poor stability, product rejection rate is high.
Summary of the invention
Technical problem to be solved in the utility model is to propose one can rapid changing knife, and resetting is accurately convenient, is applicable to the DRY CUTTING of environmental protection, and can reduces the accurate alley cutter of the cost of charp tool.
For solving the problems of the technologies described above, a kind of accurate alley cutter of the utility model comprises cutter head and cutter hub, described cutter head adopts carbide alloy to make, described cutter hub adopts steel alloy to make, described cutter head is connected with being welded and fixed between cutter hub, solder side is plane-welding, and described cutter hub is provided with tool-holder and behave affectedly body, described in clamp cavity inner wall surface be provided with screw thread.
The accurate alley cutter of above-mentioned one, described in clamp on the medial extremity of cavity, be provided with venthole inside the joint portion of described cutter head and cutter hub.
The accurate alley cutter of above-mentioned one, described in the screw thread clamped on cavity inner wall surface be trapezoidal thread.
The utility model, owing to have employed above-mentioned technical pattern, significantly can save cutter material, reduces the cost of charp tool; Cutter clamping mode adopts trapezoidal thread connected mode, and only need once the handling that standard wrench can be realized cutter, and installation way is solid and reliable, repetitive positioning accuracy is high; Cutting edge roundness anterior angle has worn venthole, can use Air flow, realize DRY CUTTING, reduces environmental pollution, is particularly suitable for being used as star-wheel processing milling cutter.
Accompanying drawing explanation
Fig. 1 is the structural representation of the accurate alley cutter of the utility model.
Detailed description of the invention
As shown in Figure 1, the accurate alley cutter of the utility model comprises cutter head 1 and cutter hub 5, and cutter head 1 adopts carbide alloy to make, and cutter hub 5 adopts steel alloy to make, and adopts welding manner to be fixedly linked between cutter head 1 and cutter hub 5, and solder side 2 is plane-welding.Cutter hub 5 is provided with tool-holder and behave affectedly body 6, and the inner wall surface clamping cavity 6 is provided with trapezoidal thread 4.Clamp on the medial extremity of cavity 6, be provided with venthole 3 inside cutter head 1 and the joint portion of cutter hub 5.
