The DU bearing pressing machine of the shaft sleeve of the gear pump is simple, fast and labor-saving in operation, so that the work efficiency is greatly improved. Moreover, through coordinate measuring machine (CMM) detection, the verticality, the coaxiality and the bounce of the shaft sleeve of the gear pump, into which after a DU bearing is pressed, are respectively minimum in tolerance.
Description
Technical field
The present invention relates to gear pump production equipment field, be specifically related to the DU bearing press of gear pump sleeve.
Background technology
Axle sleeve is the important composition parts of gear pump, in order to improve the anti-wear performance of product, presses in axle sleeve hole as required and puts the DU bearing, and former old technique is manually to use rubber hammer that the DU bearing is knocked in the axle sleeve hole.The axle journal of the gear of installing in the axle sleeve and end face squareness require very high, and be therefore very high to perpendicularity, the axiality of axle sleeve centre bore and end face and the requirement of beating.Axle sleeve is aluminum products, and material is softer, knock in by hand, very difficult assurance pack into behind the DU bearing axle sleeve perpendicularity, axiality and beat, not only be difficult to the requirement of ensuring the quality of products, and operating efficiency is also very low.
Summary of the invention
The technical problem to be solved in the present invention provides the DU bearing press of gear pump sleeve, mechanical press mounting, and the axle sleeve perpendicularity is good, and axiality and beating all meets the requirements, and the time and labour saving, increases work efficiency.
The present invention is achieved through the following technical solutions:
The DU bearing press of gear pump sleeve, described pressing machine comprises frame, extensible member, upper holder block, lower lock block, described frame is comprised of upper platen, lower platen and the column that is positioned between the two, extensible member is located at the upper platen top, the expansion link of extensible member is fixedly connected with upper holder block after passing upper platen, the upper holder block below is provided with two prominent compression legs, lower lock block is fixed on the lower platen, lower lock block is provided with cavity, the upper plate of cavity top is provided with two through holes, and lead to the hole site is vertical with prominent compression leg.
The further improvement project of the present invention is, described lower lock block both sides are provided with lead, and the lead activity interted upper holder block.
The present invention further improvement project is that described lead activity is fixedly connected with upper platen after passing upper holder block.
The present invention more further improvement project be, the lower panel of described lower lock block is provided with two location protruded stigmas, protruded stigma position, described location is vertical with through hole.
The present invention more further improvement project be, described location protruded stigma places in the shrinkage pool on the lower panel, protruded stigma below, location is provided with spring.
The present invention further improvement project is that described extensible member is cylinder or oil cylinder.
The present invention further improvement project is that described pressing machine is located on the operating desk.
The present invention compared with prior art has following obvious advantage:
One, the present invention is the special equipment that gear pump sleeve press-fits DU bearing operation, gear pump shaft is mounted in the cavity of lower lock block, the DU bearing is put into the through hole of the upper plate of cavity top, extensible member is connected with hand-operated direction valve, it is flexible to handle extensible member by hand-operated direction valve, two prominent compression legs that extensible member drives on the upper holder block are advanced downwards, prominent compression leg with the DU bearing press mounting in the hole of gear pump sleeve.Simple to operate, quick, greatly improved operating efficiency, and be pressed into gear pump sleeve perpendicularity, the axiality behind the DU bearing and beat, detect through CMM, all in minimal tolerance.
Two, the lower plate of lower lock block of the present invention is provided with the location protruded stigma, when being convenient to holding gears pump shaft cover, positions, guarantee that prominent compression leg, through hole, gear pump shaft trepanning on the upper holder block are vertical, protruded stigma below, location is provided with spring, when press-fiting, pressure is even, and the DU bearing is easier to be press-fit into place.
Description of drawings
Fig. 1 is stereogram of the present invention.
The specific embodiment
As shown in Figure 1, pressing machine of the present invention comprises frame 1, extensible member 2, upper holder block 3, lower lock block 4, described frame 1 is comprised of upper platen 11, lower platen 12 and the column 13 that is positioned between the two, extensible member 2 is located at upper platen 11 tops, the expansion link of extensible member 2 is fixedly connected with upper holder block 3 after passing upper platen 11, upper holder block 3 belows are provided with two prominent compression legs 31, lower lock block 4 is fixed on the lower platen 12, lower lock block 4 is provided with cavity 41, the upper plate 42 of cavity 41 tops is provided with two through holes 43, and through hole 43 positions are vertical with prominent compression leg 31.
Described lower lock block 4 both sides are provided with lead 5, and lead 5 activities interted and are fixedly connected with upper platen 11 behind the upper holder block 3.
The lower plate 44 of described cavity 41 belows is provided with two location protruded stigmas 45, and protruded stigma 45 positions, described location are vertical with through hole 43.
Described location protruded stigma 45 places in the shrinkage pool 46 on the lower plate 44, and protruded stigma 45 belows, location are provided with spring.
