Abstract
The utility model discloses a detachable carbide-tipped hob which comprises a cutter shaft, a hob body and fixed rings, wherein the hob body is composed of a plurality of cutter teeth distributed on the periphery of the cutter shaft, and the fixed rings are mounted at two ends of the hob body. The detachable carbide-tipped hob is characterized in that the cutter shaft can be detached with the cutter teeth; a plurality of positioning blocks are arranged on the connecting positions of the cutter teeth and the cutter shaft, and sunk holes corresponding to the positioning blocks are formed in the cutter shaft; two adjacent cutter teeth are buckled with each other. The detachable carbide-tipped hob has the benefits that the cutter shaft and the cutter teeth of the tipped hob are detachable; if part of the hob is damaged, only the damaged part is replaced, so that the cost is reduced; the front and back cutter teeth are buckled with each other, so that the firmness is increased.
Description
Technical field
The utility model relates to a kind of detachable carbide alloy empiecement hobboing cutter, belongs to field of mechanical technique.
Background technology
Gear hob is the processing external toothing straight-tooth commonly used and the cutter of helical gears.During Gear Processing, hobboing cutter engages according to a pair of helical tooth crop rotation space each other with workpiece, with the speed ratio rotation of fixing, by the cutter tooth profile of tooth envelope of each adjacent position of cutting at one time, becomes tooth-formation of gear.Middle Gear Hob with Small Modulus is generally that entirety adopts high-speed steel to manufacture, and the hobboing cutter of modulus more than 10 millimeters, in order to save high-speed steel, avoided forging difficulty and improving metallographic structure, often adopts empiecement structure.The version of empiecement hobboing cutter is a lot, and conventional is edge rack structure, and cutter tooth part is made spline-simulating with high-speed steel, after heat treatment, is fastened on cutter hub.With carbide alloy, manufacture hobboing cutter, can significantly improve cutting speed and cutting efficiency.Cutter tooth and the cutter hub of existing empiecement hobboing cutter are solidified as a whole, and in use easily cause wearing and tearing, damage, and change the hobboing cutter damaging and need to abandon whole hobboing cutter, cause like this waste of material, and cost is high.
Utility model content
Technical problem to be solved in the utility model is to overcome the problems referred to above, and a kind of detachable carbide alloy empiecement hobboing cutter is provided, and cuts the waste, reduces costs.
The technical solution of the utility model is: a kind of detachable carbide alloy empiecement hobboing cutter, comprise by cutter shaft, be distributed in the cutter hub that the multiple cutters tooth in cutter shaft periphery form and the retainer plate that is arranged on cutter hub two ends, it is characterized in that: described cutter shaft and cutter tooth are detachable, described cutter tooth is being provided with several locating pieces with the junction of cutter shaft, and cutter shaft is provided with the pit-holes corresponding with locating piece; Between adjacent two cutters tooth, fasten.
The bottom, front side of cutter tooth described in the utility model has projection, and bottom rear has groove, and the groove of front cutter tooth of adjacent cutter tooth engages with the projection of rear cutter tooth.
The beneficial effects of the utility model are: cutter shaft and the cutter tooth of the utility model empiecement hobboing cutter are detachable, and broken parts hobboing cutter only need to be changed broken parts, saves cost; Front and back cutter tooth fastens, and increases fastness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model cutter shaft.
Fig. 3 is the structural representation of the utility model cutter tooth.
The specific embodiment
Now by reference to the accompanying drawings the utility model is further described:
As shown in Figure 1, a kind of detachable carbide alloy empiecement hobboing cutter, comprise by cutter shaft 2, be distributed in the cutter hub that the multiple cutters tooth 1 in cutter shaft periphery form and the retainer plate 3 that is arranged on cutter hub two ends, cutter shaft 2 is detachable with cutter tooth 1, cutter tooth 1 is being provided with several locating pieces 5 with the junction of cutter shaft 2, and cutter shaft 2 is provided with the pit-holes corresponding with locating piece 54; The bottom, front side of cutter tooth 1 has projection 6, and bottom rear has groove 7, and the groove 7 of front cutter tooth 1 of adjacent cutter tooth 1 engages with the projection 6 of rear cutter tooth 1, increases the fastness of cutter tooth.
