Abstract
The utility model is related to axis positioning devices of buckling, the positioning device of specifically a kind of crankshaft of motorcycle timing sprocket, including, pressure cylinder is shipped and resell on another market, positioning key, positioning pin, the pressure cylinder is stainless steel hollow cylinder, and the pressure cylinder lower end is two positioning pins, and bar shaped positioning spline is arranged in the pressure cylinder side, installation is shipped and resell on another market in positioning spline, the positioning key that the upper installation shipped and resell on another market can rotate.The present apparatus is simple in structure, registration, because positioning key is to progressively disengage crank keyway, and positioning pin is stuck in always in sprocket indentations, and the timing angle of sprocket wheel is effectively ensured.
Description
Technical field
The utility model is related to axis positioning device of buckling, the positioning device of specifically a kind of crankshaft of motorcycle timing sprocket.
Background technology
In daily motorcycle buckles axis process, the chain wheel load required to sprocket wheel angle especially is needed at some
During system, core of the sprocket wheel at production and processing sprocket wheel producer is accurately positioned, however in existing pressing sprocket equipment, mostly
Sprocket wheel is suppressed using the form of punching press, however punching press does not have effective auxiliary locator so that many to stamp out
Sprocket wheel it is not up to standard, sprocket wheel timing angle deviation is excessive so that the presence largely done over again.
Utility model content
The utility model be intended to provide it is a kind of simple in structure, it is easy to operate, the one of sprocket wheel timing angle can be accurately positioned
The positioning device of kind crankshaft of motorcycle timing sprocket.
The technical solution adopted in the utility model is such：A kind of positioning device of crankshaft of motorcycle timing sprocket, this
Device includes that pressure cylinder is shipped and resell on another market, positioning key, positioning pin, and the pressure cylinder is stainless steel hollow cylinder, and the pressure cylinder lower end is two
A positioning pin, the pressure cylinder side are arranged bar shaped positioning spline, install and ship and resell on another market in positioning spline, the upper installation shipped and resell on another market can rotate
Positioning key.
It further limits, the positioning key is half-round metal block, and tiny control lever is arranged in metal derby leading portion.
Further limit, the positioning spline on the pressure cylinder excircle with two pin hole center of end face at certain folder
Angle.
It further limits, the pin hole on the positioning key to form hinge knot with pin hole at pressure cylinder outer circle keyway by shipping and reselling on another market
Structure.
The utility model has the beneficial effects that：The present apparatus is simple in structure, registration, because positioning key is to progressively disengage crank
Keyway, and positioning pin is stuck in always in sprocket indentations, and the timing angle of sprocket wheel is effectively ensured.
Description of the drawings
The utility model can be further illustrated by the nonlimiting examples that attached drawing provides；
Attached drawing 1 is the positive structure schematic of the utility model；
Attached drawing 2 is the side structure schematic diagram of the utility model；
Main element symbol description is as follows：
1, pressure cylinder；2, it ships and resell on another market；3, positioning key；4, positioning pin；5, operating lever.
Specific implementation mode
It is right with reference to the accompanying drawings and examples in order to make those skilled in the art that the utility model may be better understood
Technical solutions of the utility model further illustrate.
As shown in Figure 1 and Figure 2, a kind of positioning device of crankshaft of motorcycle timing sprocket, the present apparatus include that pressure cylinder 1 is shipped and resell on another market
2, positioning key 3, positioning pin 4, the pressure cylinder 1 are stainless steel hollow cylinder, and 1 lower end of pressure cylinder is two positioning pins 4, described
Bar shaped positioning spline is arranged in 1 side of pressure cylinder, in positioning spline installation ship and resell on another market 2, the positioning key 3 that the upper installation shipped and resell on another market can rotate.
Preferably, the positioning key 3 is half-round metal block, and tiny control lever 5 is arranged in metal derby leading portion.
Preferably, the positioning spline on 1 excircle of pressure cylinder with it is at a certain angle with two pin hole center of end face.
Preferably, the pin hole on the positioning key 3 to form hinge arrangement with pin hole at pressure cylinder outer circle keyway by shipping and reselling on another market.
The specific implementation process of the utility model is such：When being pressed sprocket wheel, positioning key 3 is directed at crank Woodruff key slots and keyways
Direction, pressure cylinder end face positioning pin stick into sprocket indentations and are pressed again, and positioning key progressively disengages crank key during press fitting
Slot, and positioning pin is stuck in always in sprocket indentations, and the timing angle of sprocket wheel can be effectively ensured.
A kind of positioning device of crankshaft of motorcycle timing sprocket provided by the utility model is described in detail above.
The explanation of specific embodiment is merely used to help understand the method and its core concept of the utility model.It should be pointed out that for this
It, without departing from the principle of this utility model, can also be to the utility model for the those of ordinary skill of technical field
Some improvement and modification can also be carried out, and modifications and modifications also fall within the protection scope of the claims of the utility model.
