Description

Engine right case bearing press

Technical field

The utility model relates to a kind of pressing machine that is used for two bearing press mountings on the motorcycle engine right case.

Technical background

Along with developing rapidly of motorcycle industry, the demand of motorcycle engine is increasing.In order to adapt to engine production assembling in enormous quantities, high efficiency, the flowing water assembling of carrying out motorcycle engine with engine line has replaced dispersion assembling mode in the past gradually.In the production assembling of motorcycle engine, press-fiting of two bearings is one of its operation on the engine right case, press-fiting of this two bearings is to adopt two simple pressing equipment to press-fit respectively at present, its assembling process is loaded down with trivial details, service speed is slow, efficiency of assembling is extremely low, can not adapt to the quick operation of engine line.

The utility model content

Technical problem to be solved in the utility model provides a kind of engine right case bearing press, is used for online the press-fiting of motorcycle engine right case two bearings, to adapt to the quick operation of engine line.

Engine right case bearing press described in the utility model, comprise frame and the base that is fixed on the frame, vertical fixing has big guide pillar on base, and guide plate is installed on it, and guide plate is slidingly matched with big guide pillar, on big guide pillar, be set with the compression spring, it is fixed with pressing plate at the guide plate lower surface between base and guide plate, the guide plate top is provided with pneumatic cylinder, its piston rod is fixed on the guide plate, and guide plate can be moved up and down at the effect lower edge of pneumatic cylinder guide pillar.

Vertical fixing has little guide pillar on base, and location-plate is installed on it, location-plate be positioned at pressing plate under, and be slidingly matched with little guide pillar, on little guide pillar, being set with the compression spring, it is between base and location-plate, offer through hole on the location-plate, and be fixed with at least two alignment pins.

Vertical fixing has two reference columns on base, two reference column axis are by the through hole on the location-plate, promptly two reference columns are positioned at the orthographic projection scope of location-plate through hole, make when location-plate to be subjected to the pressure at right angle effect when guide pillar moves down, and two reference columns can be given prominence to from the through hole of location-plate.And the relative position on the relative position on two reference columns and the location-plate between the alignment pin and the engine right case between two bearings hole and the locating hole is consistent.

During work this pressing machine is connected with electrical control equipment, earlier two bearings is placed on two reference column tops respectively, again the engine right case is positioned on the location-plate, and, press start button and can carry out press-fiting of two bearings by the location of the alignment pin on the location-plate.

The utility model makes press-fiting of right case bearing drive pressing plate then by pneumatic cylinder promotion guide plate and finishes owing to have this kind structure, and pressing plate operates steadily, and pressure is even, can guarantee the assembly quality of bearing; And press-fiting of two bearings can disposablely be finished simultaneously on the engine right case, and it press-fits the process simple and fast, can adapt to the speed of service of engine line fully.

Description of drawings

Now in conjunction with the accompanying drawings the utility model is described in further detail.

Fig. 1 looks schematic diagram for the master of a kind of concrete structure of engine right case bearing press described in the utility model;

Fig. 2 looks schematic diagram for the left side of Fig. 1;

Fig. 3 is the cross-sectional schematic of A-A line among Fig. 1.

The engine right case is partly represented in two-dot chain line among the figure.

The specific embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, this engine right case bearing press comprises frame 7 and the base 8 that is fixed on the frame 7, vertical fixing has four big guide pillars 3 on base 8, four big guide pillar 3 rectangular being distributed on the base 8, guide plate 4 is installed on it, guide plate 4 is slidingly matched with big guide pillar 3, on each big guide pillar 3, all be set with compression spring 6, it is between base 8 and guide plate 4, be fixed with pressing plate 5 at guide plate 4 lower surfaces, guide plate 4 tops are provided with pneumatic cylinder 1, and its piston rod 2 is fixed on the guide plate 4, and guide plate 4 can be moved up and down at the effect lower edge of pneumatic cylinder 1 guide pillar 3.

Vertical fixing has four little guide pillars 10 on base 8, four little guide pillar 10 rectangular being distributed on the base 8, location-plate 11 is installed on it, location-plate 11 be positioned at pressing plate 5 under, and be slidingly matched with little guide pillar 10, on each little guide pillar 10, all be set with compression spring 9, it is between base 8 and location-plate 11, to overcome this compression spring force along little guide pillar 10 when descending when location-plate 11 is subjected to pressure at right angle, and when pressure disappears, location-plate 11 will be back to original position under 9 effects of compression spring.Offer through hole 14 on the location-plate 11, and be fixed with two alignment pins 12.

Vertical fixing has two reference columns 13 on base 8, but bearing passes through its endoporus placement positioning on two reference columns, 13 tops, two reference columns 13 are outstanding from the through hole 14 of location-plate 11 by the through hole 14 of location-plate 11, make two reference columns, 13 tops exceed location-plate 11 upper surfaces, but this size that exceeds should make engine right case placement positioning after on the location-plate 11, and the bearing that place on two reference columns, 13 tops does not interfere with the engine right case.Relative position on relative position on two reference columns 13 and the location-plate 11 between two alignment pins 12 and the engine right case between two bearings hole and corresponding two locating holes is consistent, after making the engine right case be positioned on the location-plate 11 by two alignment pins 12, the two bearings hole on the right case is just in time corresponding down in vertical direction with the two bearings on two reference columns, 13 tops.

During work this pressing machine is connected with electrical control equipment, earlier two bearings is placed on two reference columns, 13 tops respectively, again the engine right case is positioned on the location-plate 11, and by two alignment pins, 12 location on the location-plate 11, press start button, guide plate 4 in pneumatic cylinder 1 effect lower edge big guide pillar 3 descending, the compression spring force that overcomes on the little guide pillar 10 to the pressing plate 5 contact engine right cases continues descending, in the dead eye that the bearing on two reference columns 13 is pressed on the right case, afterwards guide plate 4 in pneumatic cylinder 1 effect lower edge big guide pillar 3 up, and location-plate 11 is back to original position under the compression spring on the little guide pillar 10 9 effect, takes off right case and promptly finishes press-fiting of two bearings on the right case.

Pressing machine described in the utility model also can be connected with autoloader and is used, and the feeding manipulator of autoloader can be delivered to bearing on two reference columns 13 from the feeder outlet automatically, to realize bearing feeding automation.
