Abstract

The utility model discloses a pulling device for assembling a bearing. The pulling device comprises a connection block, a screw rod and two pulling plates, wherein a thread hole is formed in the connection block; the screw rod is in threaded connection with the thread hole; a connection hole is formed in each of the two sides of the connection block; the upper ends of the pulling plates are connected with the connection holes through bolts; a bent part is arranged at the lower end of each pulling plate. The pulling device for assembling the bearing has the advantages that due to the screw rod and the pulling plates, the acting fore of a user is amplified through the screw rod, and high pulling force is generated; the structure is simple and portable, the production cost is low, and the pulling device is wide in application range.

Description

For assembling the tractor of bearing

Technical field

The utility model relates to a kind of tractor, more precisely a kind of for assembling the tractor of bearing.

Background technique

When producing bearing, the outer ring that need to first produce bearing, the inner ring of regeneration output bearing, then by inner ring and pressing together, but the cost of this tractor of the prior art is higher, is not suitable for midget plant and uses, while being also not suitable for individual's maintenance bearing, use, Applicable scope is less.

Model utility content

The utility model is mainly to solve the existing technical problem of prior art, thereby provide a kind of with screw rod and drawing plate, can amplify by this screw rod user's active force, produce larger pulling force, structure is comparatively simple, light, cost of production is lower, Applicable scope wider for assembling the tractor of bearing.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:

A kind of for assembling the tractor of bearing, comprise a contiguous block and a screw rod, on described contiguous block, be provided with a tapped hole, described screw rod is threaded with described tapped hole, described also comprises two drawing plates for assembling the tractor of bearing, the both sides of described contiguous block are respectively arranged with an attachment hole, and the upper end of described drawing plate and described attachment hole are bolted, and the lower end of described drawing plate is provided with a bending part.

As the utility model preferred embodiment, the left and right sides of described drawing plate is respectively arranged with the edge of a projection, and described edge extends to the end of described bending part from the upper end of described drawing plate.

Of the present utility modelly for assembling the advantage of the tractor of bearing, be: with screw rod and drawing plate, can by this screw rod, amplify user's active force, produce larger pulling force, structure is comparatively simple, light, and cost of production is lower, and Applicable scope is wider.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is of the present utility model for assembling the perspective view of the tractor of bearing;

Fig. 2 be in Fig. 1 for assembling the plan view of the tractor of bearing;

Fig. 3 is the perspective view of the contiguous block in Fig. 1;

Fig. 4 is the perspective view of the drawing plate in Fig. 1;

Wherein:

1, contiguous block; 11, tapped hole; 12, attachment hole;

2, screw rod;

3, drawing plate; 31, bending part; 311, edge.

Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.

As shown in Figure 1 and Figure 2, a kind of for assembling the tractor of bearing, comprise a contiguous block 1 and a screw rod 2, as shown in Figure 3, on this contiguous block 1, be provided with a tapped hole 11, this screw rod 2 is threaded with this tapped hole 11, should also comprise two drawing plates 3 for assembling the tractor of bearing, the both sides of this contiguous block 1 are respectively arranged with an attachment hole 12, and the upper end of this drawing plate 3 and this attachment hole 12 are bolted, as shown in Figure 4, the lower end of this drawing plate 3 is provided with a bending part 31.Use the lower end of this screw rod 2 to hold out against the upside of bearing inner race, use this bending part 31 to hook the downside of bearing outer ring, rotate this screw rod 2, can amplify user's active force, produce larger pressure, the inner ring of bearing is snapped in the outer ring of this bearing, reach the object of assembling bearing.

As shown in Figure 1, Figure 2, Figure 4 shows, the left and right sides of this drawing plate 3 is respectively arranged with the edge 311 of a projection, and this edge 311 extends to the end of this bending part 31 from the upper end of this drawing plate 3.The edge 311 of this projection is not only conducive to prevent the slippage of the outer ring of bearing, be conducive to increase the rigidity of this drawing plate 3 and this bending part 31 simultaneously, make this drawing plate 3 and this bending part 31 can bear larger power, more not yielding, further reduce production costs lower, be more conducive to individual and use.

Below only with a mode of execution, mentality of designing of the present utility model is described, in the situation that system allows, the utility model can expand to external more function module simultaneously, thereby expands to greatest extent its function.

The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
