Abstract
The utility model discloses an auxiliary unit. for casting a chain wheel The auxiliary unit is provided with a single-side chain, wherein the upper part of the single-side chain is provided with projections, and the projections are circled by the chain to form a tooth notch of a chain wheel tooth, then the auxiliary unit is placed into a sand box, so that a mold of the chain wheel can be conveniently obtained. By adopting the auxiliary unit for casting the chain wheel, the convenience in combination can be realized according to the size and the teeth number of a gear, the structure is simple, and the convenience in production is realized.
Description
Technical field
The utility model relates to a kind of chain wheel casting auxiliary member, belongs to casting field.
Background technology
The chain pitch wheel of traditional low precision generally forms by special-purpose mould or lathe turning, and this processing mode, cost compare is high, when the number of teeth and diameter change, need to make new mould or write new turning program, and cost of labor is also higher.
Utility model content
The purpose of this utility model is:
A kind of technical scheme that can address the above problem is provided.
The utility model is realized by the following method:
A kind of chain wheel casting auxiliary member, described chain wheel casting auxiliary member comprises by some hard sheets and is rotationally connected mutually one side chain, the protruding block forming, described protruding block is prism-shaped projection, described protruding block is disposed on the hard sheet of described one side chain, and the axis of described protruding block is perpendicular to the horizontal plane of hard sheet and be all positioned at the same side.
As further innovation of the present utility model, the cross section of described protruding block is isosceles trapezoid, and described trapezoidal upper base is evagination camber line, and described trapezoidal two formed angles of waist are greater than 90 °.
beneficial effect
The utility model is by an one side chain, and on top, protruding block is set, by enclosing of chain, make protruding block enclose the tooth portion breach of sprocket, the utility model is placed in sandbox again, just can obtains easily the mould of sprocket wheel, the utility model can combine according to the size of gear and the number of teeth easily, simple in structure, easy to make.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
Fig. 3 is use state diagram of the present utility model.
In figure: 1, one side chain; 2, bearing pin; 3, protruding block.
The specific embodiment
Below in conjunction with accompanying drawing, be described further
A kind of chain wheel casting auxiliary member, described chain wheel casting auxiliary member comprises by some hard sheets and is rotationally connected mutually one side chain 1, the protruding block 3 forming, described protruding block 3 is prism-shaped projection, described protruding block 3 is disposed on the hard sheet of described one side chain 1, and the axis of described protruding block 3 is perpendicular to the horizontal plane of hard sheet and be all positioned at the same side;
The cross section of described protruding block 3 is isosceles trapezoid, and described trapezoidal upper base is evagination camber line, and described trapezoidal two formed angles of waist are greater than 90 °.
During use, open the wherein bearing pin 2 of two pitch chain bars, according to the number of teeth of sprocket wheel and large young pathbreaker's auxiliary member ring, finally fixing by bearing pin 2, then pack in sandbox, be made into sprocket wheel mould.
