Description

Bearing grabbing device

Technical Field

The utility model relates to the field of mechanical maintenance tools, in particular to a bearing grabbing device.

Background

As is well known, bearings are used in various stages of industrial production and manufacturing, and are easily damaged due to improper operation or excessive load, so that replacement and maintenance of bearings are also important steps in industrial production. In the process of mechanical maintenance and overhaul, the bearing is always dismantled and installed, the special tool for dismantling the bearing is various in types, the design is single, different types of bearings need to be chosen to dismantle and grab, the replacement without stopping is realized, the production efficiency is greatly reduced, the unnecessary expenditure is increased, the production cost is improved, and the unnecessary economic loss is caused.

In order to solve the above problems, the present invention provides a bearing gripping device.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a bearing grabbing device, which aims to solve the problem that a bearing disassembling tool is single in design and only can grab a single type of bearing, so that grabbing efficiency is low, and the problem that production cost is high due to maintenance and purchase of different types of grabbing devices is solved.

In order to achieve the purpose, the utility model provides the following technical scheme:

a bearing grabbing device comprises a top plate and expansion screws, wherein the bottom of the top plate is provided with a plurality of clamping plates; a through hole is formed in the middle of the top plate, and a screw rod of the expansion screw penetrates through the through hole; and a rotating assembly is arranged at one end of the screw rod, which is far away from the expansion pipe.

Furthermore, the rotating assembly is a nut, and the nut and the screw are matched with each other.

Furthermore, the number of splint is two, and two splint use the screw rod to set up as the central axis symmetry.

Compared with the prior art, the utility model has the beneficial effects that:

firstly, fixing a bearing base to be disassembled through a fixing component, and then putting an expansion pipe on an expansion screw into the inner diameter of a bearing; then, a nut on the expansion screw is rotated, and the expansion pipe is fixed in the bearing by utilizing the expansion effect of the expansion screw; then sleeving the top plate and the clamping plates on the top plate on the screw rod, and clamping the bottoms of the clamping plates on the bearing bases; finally, the rotating assembly is rotated, the rotating assembly drives the expansion screw and the bearing fixed with the expansion screw to move upwards while rotating on the screw rod, so that the bearing is detached from the bearing base; meanwhile, the bearings with different sizes can be disassembled, and time and labor are saved in the disassembling process.

Drawings

The accompanying drawings, which are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate embodiments of the utility model and together with the description serve to explain the principles of the utility model and not to limit the utility model.

In the drawings:

fig. 1 is a schematic view of the structure of the present invention.

In the figure: 1. a top plate; 2. a nut; 3. an expansion screw; 4. a screw; 5. a splint; 6. a bearing; 7. a bearing base; 8. and (6) fixing the assembly.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The utility model provides the following technical scheme:

as shown in the figure, the first and second,

the first embodiment is as follows:

a bearing grabbing device comprises a top plate 1 and expansion screws 3 (the structure and the working principle of the expansion screws are the prior art and comprise expansion pipes and screw rods, the specific structure and the working principle of the expansion screws are not described herein any more), clamping plates 5 are arranged at the bottom of the top plate 1, the top plate 1 is fixedly connected with the clamping plates 5, the number of the clamping plates 5 is a plurality, and the plurality of clamping plates 5 are uniformly distributed at the bottom of the top plate 1; a through hole is formed in the middle of the top plate 1, and a screw rod 4 of the expansion screw 3 penetrates through the through hole; and a rotating assembly is arranged at one end of the screw rod 4, which is far away from the expansion pipe, and the rotating assembly is matched with the screw rod 4.

Further, the rotating assembly is a nut 2, and the nut 2 and the screw rod 4 are matched with each other. This structure is simple relatively, need rotate nut 2 through the spanner when using, nut 2 is because roof 1 and splint 5's fixed action for nut 2 is at the unable downstream of pivoted in-process, then nut 2 can only drive screw rod 4 upward movement in the inflation screw 3 at the pivoted in-process, screw rod 4 then drives the inflation pipe and upwards moves with inflation pipe reciprocal anchorage's bearing 6 at upward movement's in-process, thereby dismantles bearing 6 from bearing base 7. The spanner rotates around screw rod 4 as the center pin in the rotation process that the spanner drives nut 2, utilizes the lever principle of spanner length and the clamping part of spanner to reduce staff's working strength.

Further, the number of the clamping plates 5 is two, and the two clamping plates 5 are symmetrically arranged by taking the screw rod 4 as a central axis. But the best and most stable effect is that the splints 5 are arranged in three, and the three splints 5 are in a tripod structure.

According to the structure, the specific working principle is as follows:

firstly, fixing a bearing base 7 to be disassembled through a fixing component 8, and then putting an expansion pipe on an expansion screw 3 into the inner diameter of a bearing 6; then the nut 2 on the expansion screw 3 is rotated, and the expansion pipe is fixed in the bearing 6 by utilizing the expansion effect of the expansion screw 3; then the top plate 1 and the clamping plate 5 on the top plate 1 are sleeved on the screw rod 4, and the bottom of the clamping plate 5 is clamped on the bearing base 7; and finally, rotating the rotating assembly, and driving the expansion screw 3 and the bearing 6 fixed with the expansion screw 3 to move upwards while the rotating assembly rotates on the screw rod 4, so that the bearing 6 is detached from the bearing base 7.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
