Description
Technical field
The utility model relates to a kind of press-loading apparatus, is specifically related to a kind of gear shaft straight pin press-loading apparatus of quick location.
Background technology
Increasingly competitive along with automobile industry improves the quality of products, and reduces product cost and become the subject matter that each auto parts and components manufacturer pays close attention at present.The gear shaft straight pin of existing rack and pinion steering gear press-fits and mainly contains following several press-fit approach:
The first, use general gear shaft straight pin accessory to press-fit, this kind accessory need be beaten straight pin in advance with "painted-face" character in opera, changes accessory working pressure machine then and press-fits, and this kind mode press-fits the problem that causes several aspects easily:
1, straight pin distortion: straight pin is pressed into the compressive strain of gear shaft back upper place, causes waste product;
2, straight pin is askew: after being pressed into gear shaft and dressing up Spool assembly, cause properties of product defective easily.
More than two kinds of problems beat inaccurately in advance mainly due to "painted-face" character in opera, the artificial pressure imbalance can not guarantee that fixedly hammer force and gear shaft no-fix cause.
The second, the design specialist lathe press-fits, and professional lathe has the straight pin storehouse, is provided with automatic guiding function, has following functional steps, and following steps are machine operation:
1, using pre-determined bit rod (pin more smaller than gear shaft straight pin) to insert the gear shaft pin-and-hole before the dress straight pin ajusts the position;
2, straight pin is put in mobile straight pin storehouse, falls in the press mounting hole by the guiding awl;
3, the pad post is compressed into the gear shaft pin-and-hole with straight pin;
Straight pin press-fits stable, but machinery requirement 3 step operation, the operation beat is slower.
More than first kind of mode have and press-fit the advantage that beat is fast, price is low, but poor stability causes a large amount of waste products easily; The second way has the advantage that press-fits effect stability, but productive temp is slow, can not satisfy existing working ability, and device requirement quantity is big, and involves great expense, and lathe does not have versatility.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, easy to operate, press-fit beat fast, press-fit effective, cheap, press-fit because "painted-face" character in opera is beaten inaccurate in advance to solve the existing accessory that adopts, the artificial pressure imbalance, cause straight pin to be pressed into the back distortion, cause waste product, and adopt professional lathe to press-fit, productive temp is slow, can not satisfy existing working ability, device requirement quantity is big, and involve great expense, lathe does not have the gear shaft straight pin press-loading apparatus of the quick location of versatility problem.
The utility model is to realize above-mentioned purpose by the following technical solutions:
A kind of gear shaft straight pin press-loading apparatus of quick location, it is made of supporting plate, straight pin clamp, alignment pin, V-arrangement back-up block, gear shaft locating piece, baffle plate and limiting plate, it is characterized in that: supporting plate one end is fixed with the V-arrangement back-up block by hex bolts and pad; The supporting plate other end is movably installed with the straight pin clamp by alignment pin; Be provided with back-moving spring between the handle of straight pin clamp, by set bolt limiting plate be installed on the supporting plate of straight pin clamp below, by baffle plate the gear shaft locating piece is installed on the limiting plate.
The utility model beneficial effect compared with prior art is:
The gear shaft straight pin press-loading apparatus of location is supportive body with the supporting plate fast, during work by straight pin clamp clamping work pieces (straight pin), after gear shaft inserts locating piece, use the pin-and-hole position in the logical no-go gage insertion of the gear shaft pin-and-hole straight pin clamp, and pass the gear shaft pin-and-hole, determine the position consistency that gear shaft axial dimension and pin press-fit, put into straight pin then, the working pressure machine press-fits gear shaft, after the height of straight pin clamp and supporting plate determined that gear shaft is pressed into straight pin, pin spilt the length of gear shaft.The gear shaft straight pin press-loading apparatus cost economic that should locate fast, press-fit that beat is fast, good stability, solved that existing employing accessory press-fits because "painted-face" character in opera is beaten inaccurate in advance, the artificial pressure imbalance causes straight pin to be pressed into the back distortion, causes waste product, and adopt professional lathe to press-fit, productive temp is slow, can not satisfy existing working ability, and device requirement quantity is big, and involve great expense, lathe does not have the problem of versatility.The gear shaft straight pin press-loading apparatus of location is simple in structure, easy to operate fast, is specially adapted to the gear shaft straight pin and press-fits use.
Description of drawings
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is a plan structure schematic diagram of the present utility model,
Fig. 3 is a left TV structure schematic diagram of the present utility model.
Among the figure: 1, supporting plate, 2, the straight pin clamp, 3, alignment pin, 4, V-arrangement back-up block, 5, the gear shaft locating piece, 6, baffle plate, 7, limiting plate, 8, hex bolts, 9, back-moving spring, 10, set bolt, 11, piece-holder position, 12, gear shaft (workpiece), 13, straight pin (workpiece), 14, pad.
