Description
Technical field
The invention belongs to technical field of tooling clamps, specifically, the particularly press-fitting tool of crankshaft box of motorcycle engine bearing.
Background technology
At present, each motorcycle engine manufacturer all need be pressed into bearing in the bearing chamber of crankcase by the frock of special use in the assembling crankcase.Existing frock comprises column and last item, and the axial line of column and the axial line of last item are on same straight line, and existing deficiency is:
1, once can only press-fit a bearing, operating efficiency is lower;
2, when press-fiting, operating personnel need be with hand steered column, because bearing chamber is nearer apart from the madial wall of crankcase intracavity, and frock will stretch in the crankcase 50mm at least, stretch in the process of crankcase in frock, operating personnel's hand madial wall easy and crankcase intracavity interferes, and the accident that operating personnel's hand is weighed wounded happens occasionally, and security is relatively poor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of efficient height, can effectively prevents the crankcase bearing press-fitting tool that operating personnel's hand is weighed wounded.
Technical scheme of the present invention is as follows: a kind of crankcase bearing press-fitting tool, comprise column, location-plate and last item, its key is: the lower end of described column (1) is fixed on the location-plate (2), and the axial line of column (1) is perpendicular to the plate face of location-plate (2); Side at described column (1) is provided with first last item (3), the opposite side of column (1) is provided with second last item (4), the upper end of described first last item (3) and second last item (4) all fixes with location-plate (2), and the bottom surface of first last item (3) is concordant substantially with the bottom surface of second last item (4); Described first last item (3), second last item (4) and column (1) three's axial line parallels, first last item (3) is near column (1), and the distance between first last item (3) and the column (1) is less than the distance between column (1) and second last item (4).
Adopt above technical scheme, the arrangement form of two last items is corresponding with two bearing chamber positions of crankcase.In pressing bearing, earlier two bearings are placed in two bearing chamber positions of crankcase intracavity, then the lower end of two last items is stretched into respectively in the inner ring of two bearings and positioned, then with the chamfering of two bearing faces and the chamfering guiding and the location of corresponding bearing chamber open-mouth, controlling press at last drives column and moves downward (in this process operating personnel need with hand steered column), two last items are descending with column, in bearing being pressed into corresponding bearing chamber.This shows that the present invention once can press-fit two bearings, compares with background technology, improved exponentially and press-fit efficient; Simultaneously, column is between two last items, and in the process of pressing bearing, column is far away apart from the madial wall of crankcase intracavity, can prevent effectively that operating personnel's hand from being weighed wounded, and security is good.
Described first last item (3) is identical with the structure of second last item (4), form by last axis body, following axis body and middle annular boss, described upward axis body, annular boss reach down, and axis body is an integral structure, the diameter of following axis body is less than the diameter of annular boss but greater than the diameter of last axis body, the described axis body of going up stretches in the locating hole on the location-plate (2) both tight fits.Processing and fabricating is easy on the one hand for above structure, is connected firmly between last item and the location-plate; On the other hand, the following axis body of last item stretches in the inner ring of bearing and positions, and the bottom surface of annular boss and the bearing face back compressing bearing of fitting is descending, the good reliability that press-fits.
The lower end of the following axis body of described first last item (3) and second last item (4) is provided with the guiding conical surface, and axis body stretches in the bearing inner race fast under helping like this, has effectively improved the convenience of location.
Beneficial effect: the present invention processes and press-fits all simply, conveniently, can significantly improve to press-fit efficient, and prevent that effectively operating personnel's hand from being weighed wounded.

Fig. 2 is the structural representation of location-plate among the present invention.
Fig. 3 is the vertical view of Fig. 2.
Fig. 4 is user mode figure of the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
As Fig. 1, Fig. 2 and shown in Figure 3, the present invention is made of column 1, location-plate 2, first last item 3 and second last item 4, and wherein location-plate 2 is for being similar to oval-shaped slab construction, and the left end of location-plate 2 is greater than right-hand member.Position at location-plate 2 close centers has column pilot hole 2a, and the left side of this column pilot hole 2a has the first locating hole 2b, and the right side of column pilot hole 2a has the second locating hole 2c.The adjacent column pilot hole of described first locating hole 2b 2a, distance between the first locating hole 2b and the column pilot hole 2a is less than the distance between the column pilot hole 2a and the second locating hole 2c, and the first locating hole 2b, column pilot hole 2a and the second locating hole 2c three's the line of centres is on same straight line.
As can be known, the axial line of column 1 is perpendicular to the plate face of location-plate 2 from Fig. 1, Fig. 2, Fig. 3, and the lower end of this column 1 is stretched among the column pilot hole 2a on the location-plate 2, and both are by being tightly fixed, and the lower surface of column 1 is concordant with the bottom surface of location-plate 2.Described first last item 3 is identical with the structure of second last item 4, form by last axis body, following axis body and middle annular boss, described upward axis body, annular boss reach down, and axis body is an integral structure, the diameter of following axis body is less than the diameter of annular boss but greater than the diameter of last axis body, and the lower end of axis body is formed with the guiding conical surface down.The last axis body of described first last item 3 upwards stretches among the first locating hole 2b of location-plate 2, and both are by being tightly fixed, and the upper surface of first last item 3 is concordant with the end face of location-plate 2.The last axis body of second last item 4 upwards stretches among the second locating hole 2c of location-plate 2, and both are by being tightly fixed, and the upper surface of second last item 4 is concordant with the end face of location-plate 2.Described first last item 3, second last item 4 and column 1 three's axial line parallels, and the bottom surface of first last item 3 is concordant substantially with the bottom surface of second last item 4.
The present invention is used for pressing bearing like this:
As shown in Figure 4, earlier two bearings 5 are placed in two bearing chamber positions of crankcase 6 inner chambers, then the following axis body of two last items 3,4 is stretched into respectively in the inner ring of two bearings and position, then with the chamfering of two bearing faces and the chamfering guiding and the location of corresponding bearing chamber open-mouth, controlling press (not drawing among the figure) at last drives column 1 and moves downward (in this process operating personnel need with hand steered column), two last items are descending with column 1, annular boss on the last item is to lower compression bearing 5, in bearing 5 being pressed into corresponding bearing chamber.
