Abstract
The invention provides a small bearing extractor. The small bearing extractor comprises a rotary screw, a transverse beam and two vertically symmetrical clamping arms, wherein the rotary screw penetrates through a threaded hole in the center of the transverse beam, the upper portion of each clamping arm is provided with a rectangular through hole, the two ends of the transverse beam penetrate through the two rectangular through holes respectively, and the bottom ends of the clamping arms are provided with protrusions facing a threaded rod. The small bearing extractor is firm in structure and convenient to use and will not generate negative effects.
Description
Technical field
The present invention relates to bearing extractor, particularly a kind of small size bearing extracting tool.
Background technology
Bearing is the most common parts in field of mechanical technique, general sheathed being installed on body or pipe fitting of bearing, and bearing needs to remove after use some cycles, the bearing more renewing.Taking small size bearing as example, the dismounting mode of conventional small bearing is generally divided into two kinds, and a kind of is that bearing shape keeps in good situation, directly with common extracting tool dismounting; Another kind is the mode of simultaneously beaing by both sides, and bearing removal is got off.This mode is lost time and muscle power, easily damages miscellaneous part.
For the above-mentioned state of the art, be necessary to work out a kind of small size bearing extracting tool, improve the efficiency of bearing removal, and ensure that dismounting does not produce negative impact when bearing.
Summary of the invention
In order to overcome the defect of prior art, the invention provides following technical scheme:
A kind of small size bearing extracting tool, it comprises the jig arm of the vertical direction that rotary screw, crossbeam and two teams claim, described rotary screw is through the screwed hole at crossbeam center, described jig arm top is provided with rectangular through-hole, the two ends of described crossbeam are respectively through two rectangular through-hole, and the bottom of described jig arm is provided with the projection towards threaded rod.
As optimal technical scheme, the both sides of the middle and lower part of described jig arm are provided with cylindrical hole, in the relative cylindrical hole of two jig arm, wear respectively an adjusting threaded rod, the two ends of described adjusting threaded rod connect respectively rotating nut, and described rotating nut is for regulating the distance between jig arm.
As optimal technical scheme, the both sides, front and back at two ends, described crossbeam left and right are respectively equipped with symmetrical chute, and described chute is fixedly connected with outside fixture block.
As optimal technical scheme, the outer surface of described projection is concave shape, rectangle or trapezoidal.
As optimal technical scheme, the upper end of described rotary screw is provided with the surfaces of revolution, and the described surfaces of revolution is provided with rotation through hole.
As optimal technical scheme, each building block is ferrous material.
The beneficial effect that the present invention brings is: sound construction, and easy to use, do not have a negative impact.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Number in the figure is:
1, rotation threaded rod; 2, crossbeam; 3, jig arm; 4, regulate threaded rod; 5, rotating nut;
11, the surfaces of revolution; 12, rotation through hole; 21, chute; 31, projection.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
As shown in Figure 1, a kind of small size bearing extracting tool, it is characterized in that, it comprises the jig arm 3 of the vertical direction that rotary screw 1, crossbeam 2 and two teams claim, described rotary screw is through the screwed hole at crossbeam 2 centers, described jig arm 3 tops are provided with rectangular through-hole, and the two ends of described crossbeam 2 are respectively through two rectangular through-hole, and the bottom of described jig arm 3 is provided with the projection 31 towards threaded rod.
The both sides of the middle and lower part of described jig arm 3 are provided with cylindrical hole, in the relative cylindrical hole of two jig arm 3, wear respectively an adjusting threaded rod 4, the two ends of described adjusting threaded rod 4 connect respectively rotating nut 5, and described rotating nut 5 is for regulating the distance between jig arm 3.
The both sides, front and back at described crossbeam 2 two ends, left and right are respectively equipped with symmetrical chute 21, and described chute 21 is fixedly connected with outside fixture block.
Described protruding 31 outer surface is concave shape, rectangle or trapezoidal.
The upper end of described rotary screw 1 is provided with the surfaces of revolution 11, and the described surfaces of revolution 11 is provided with rotation through hole 12.
Each building block is ferrous material.
The advantage that embodiment of the present invention has is: as optimal technical scheme.
The above; it is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
