Description
Technical field
The utility model relates to a kind of machine components extracting tool, is specifically related to a kind of bearing and dismounting coupling combination tool.
Background technology
The overhaul of the equipments of current reality is on-the-spot, dismounting for bearing and shaft coupling uses more draws horse for various model, but due to following three reasons, can make to draw horse to can not get sufficient utilization in the use procedure of reality, part cannot be dismantled: the part 1, part axle assembled is more even at all, bearing and the gap between shaft coupling dorsal part and other parts less, the part that dismantle cannot be held by pulling claw reliably; 2, the accessory size of required dismounting is comparatively large, and the distance that pulling claw is stretched out is not enough to catch part; 3, bearing removal direction is longer apart from the distance of axle head, the curtailment of pulling claw.In view of above three kinds of situations occur time, operating personnel just normally cannot use and draw horse operation, can only choice for use leading screw and the pressure combination of beam or the method for dismounting of special drawing mold, and there is certain hidden danger in current used leading screw and the combination of pressure beam, safety coefficient is not high, in addition, the drawing mold used now all can only dismantle the part in same size axis, so will expose uneconomic shortcoming.
Utility model content
The purpose of this utility model is to solve the technical problem existed in prior art, provides a kind of and can alleviate operating personnel's labour intensity, the bearing improving operating efficiency and dismounting coupling combination tool.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of bearing and dismounting coupling combination tool, comprise the rectangular frame be made up of with the rear short slab being connected long slab rear end, both sides both sides long slab, the both sides, front end of described rectangular frame both sides long slab are fixed with junction steel plate respectively, dismountable square flange plate is connected with between described junction steel plate, described square flange plate has U-shaped hole, be provided with the curved plate perpendicular to rear short slab after described rectangular frame inside short slab, described curved plate is provided with jack.
Further, described junction steel plate and square flange plate are respectively equipped with the link bolt hole of multiple mutual correspondence, described junction steel plate and square flange plate are fixed by the bolt that is positioned at link bolt hole and the nut that coordinates with bolt.
Further, long slab rear section, described rectangular frame both sides is partly provided with hole for hoist.
Further, gusset is provided with outside described rectangular frame.
Further, described jack is screw jack or electric hydraulic lifting jack.
Further, described junction steel plate welds with the front end of rectangular frame both sides long slab.
The utility model hinge structure has following beneficial effect: before framework of the present utility model lacks primarily of one, the rectangular frame of short slab forms with the square flange plate having U-shaped hole, framework of the present utility model just can meet the requirement of removing various sizes bearing and shaft coupling by cooperatively interacting with jack, and ensure that dismounting part is injury-free in unloading process.Meanwhile, square flange plate with lack before the rectangular frame of short slab removably connected by bolt and nut, same framework can be used, by completing the dismantlement work of various sizes axle upper bearing (metal) and shaft coupling with the combination operation of different square flange plate, applied widely.The utility model can carry out customized according to the actual conditions at scene, structure is simple, with low cost, easy to process, long service life, the labour intensity of operating personnel can be alleviated, save working time, add operating personnel's safety coefficient, substantially increase operating efficiency, there is good application prospect and use value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model rectangular frame.
Reference numeral implication is as follows: 1, hole for hoist; 2, jack; 3, nut; 4, bolt; 5, curved plate; 6, square flange plate; 7, rectangular frame; 8, junction steel plate; 9, U-shaped hole; 10, link bolt hole; 11, gusset is strengthened.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1-2, a kind of bearing and dismounting coupling combination tool, comprise the rectangular frame 7 be made up of with the rear plate being connected long slab rear end, both sides both sides long slab, rectangular frame 7 is general frames of short slab before one of the Plate Welding that working strength and thickness are larger lacks, the both sides, front end of rectangular frame 7 both sides long slab are welded with junction steel plate 8 respectively, dismountable square flange plate 6 is connected with between junction steel plate 8, junction steel plate 8 and square flange plate 6 are respectively equipped with the link bolt hole 10 of multiple mutual correspondence, junction steel plate 8 and square flange plate 6 are fixed by the bolt 4 that is positioned at link bolt hole 10 and the nut 3 that coordinates with bolt 4, square flange plate 6 has U-shaped hole 9, the curved plate 5 perpendicular to rear plate is provided with inside plate after rectangular frame 7, curved plate 5 is provided with jack 2, jack 2 is screw jack or electric hydraulic lifting jack, long slab rear end, rectangular frame 7 both sides is respectively equipped with hole for hoist 1, be welded with outside rectangular frame 7 and strengthen gusset 11, increase the bulk strength of rectangular frame 7, ensure that rectangular frame 7 in use can be crossed and bear larger strength, can not deform.
During use, according to the size of on-the-spot actual needs dismounting part, make rectangular frame 7, again according to the diameter of required pulling force and axle when dismantling, make the square flange plate 6 with U-shaped hole 9 of all size model, the width in U-shaped hole 9, for having 120mm, 160mm, 180mm, 200mm etc., ensures the width in U-shaped hole 9 and the equal diameters of axle.Square flange plate 6 by bolt 4 nut 3 be connected with rectangular frame 7 fastening after, axle head is put into rectangular frame 7, use jack 2 by the reliable dieback of short slab after spindle nose and rectangular frame 7, after work to be prepared completes, operation jack 2, increase pressure, make the part such as bearing or shaft coupling under the effect of ever-increasing pressure, be removed.In use, in order to alleviate labour intensity when operating personnel adjusts parallel position with axle of rectangular frame 7, use two suspender belts through in the hole for hoist 1 of long slab rear end, rectangular frame 7 both sides, coordinate with chain block and overhead traveling crane dissembling combination tool of the present utility model of slinging again, ensure that the semicircular center of circle, U-shaped hole 9 is concentric with axle.
