Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to an assembly clamp for a tapered roller bearing. Background Art

[0002] Tapered roller bearings mainly consist of an inner ring, an outer ring, rollers and a cage. The cage is located between the inner ring and the outer ring, and the rollers are distributed in the rolling grooves of the cage. During assembly, the cage is first placed on the outside of the roller mold on the rotating platform. The rotation of the turntable drives the cage to rotate, and the unloading equipment located on the upper front side begins to unload the rollers one by one, so that the rollers can enter the roller grooves of the cage with the assistance of the mold grooves. After unloading, the inner ring is placed on top of the mold, and the cage is manually lifted so that the cage moves up with the rollers, and finally the rollers are surrounded by the outside of the inner ring.

[0003] In the process of implementing the solution, the inventors found that the following problems existed in the prior art and have not been well solved: after the roller enters the retaining frame, since the internal space formed between them is limited, when it moves up and is mounted on the outside of the inner ring, since the position of the inner ring placed on the mold is not fixed, when the retaining frame and the roller move up, it is very easy to touch the outer edge of the inner ring, thereby causing the inner ring to move outward, making it impossible for the retaining frame and the roller to be successfully mounted on the outside of the inner ring, so that the staff needs to manually adjust the position of the inner ring until it is successfully mounted. This method further reduces the assembly efficiency. Utility Model Content

[0004] The main purpose of the utility model is to provide an assembly fixture for a tapered roller bearing, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A tapered roller bearing assembly fixture comprises a swivel seat, a mold seat is fixed on the top of the swivel seat, both ends of the mold seat are drilled with slide grooves, tension springs are fixed on the side walls of the slide grooves that are far away from each other, push blocks are inserted and slid at the ends of the slide grooves that are close to each other, extrusion grooves are drilled on the sides of the tops of the push blocks that are close to each other, and conical pieces are provided on the sides of the tops of the push blocks that are far away from each other, two support rods 1 are fixed between the push blocks and the conical pieces respectively, a push rod motor is provided on the outer side of the swivel seat, a pressure plate is fixed to the telescopic end of the push rod motor, a support rod 2 is fixed to the end of the bottom of the pressure plate that is away from the push rod motor, and a ladder block is fixed to the bottom of the support rod 2.

[0007] Preferably, the bottom of the ladder block is located above between the extrusion grooves.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, an assembly fixture for a tapered roller bearing comprises a swivel seat 1, a mold seat 2 is fixed on the top of the swivel seat 1, both ends of the mold seat 2 are drilled with slide grooves 3, tension springs 5 ​​are fixed on the side walls of the slide grooves 3 that are away from each other, push blocks 4 are inserted and slid at the ends close to each other in the slide grooves 3, extrusion grooves 8 are drilled on the sides of the tops of the push blocks 4 that are close to each other, cone pieces 7 are provided on the sides of the tops of the push blocks 4 that are away from each other, two support rods 6 are fixed between the push blocks 4 and the cone pieces 7 respectively, a push rod motor 10 is provided on the outer side of the swivel seat 1, a pressure plate 11 is fixed to the telescopic end of the push rod motor 10, a support rod 12 is fixed to the end of the bottom of the pressure plate 11 away from the push rod motor 10, and a ladder block 13 is fixed to the bottom of the support rod 12.

[0021] Specifically, the bottom of the ladder block 13 is located above the extrusion grooves 8 , and the outer dimension of the bottom of the ladder block 13 is smaller than the inner dimension of the extrusion grooves 8 , so that it is convenient to insert the ladder block 13 into the extrusion grooves 8 to extrude the push block 4 .

[0022] Specifically, the outer side walls of the conical pieces 7 are bonded with anti-skid rubber 9 of matching size, so as to maintain anti-skid property when clamping the inner wall of the inner ring.

[0023] Specifically, the tension spring 5 is fixed to one end of the push block 4 that is close to each other. When the ladder block 13 leaves between the push blocks 4, the tension spring 5 can squeeze the push block 4 through tension, so that the conical piece 7 and the anti-slip rubber 9 can be away from the inner wall of the inner ring, making it convenient to unload the assembled parts.

[0024] Specifically, a flange foot 15 is provided under the push rod motor 10, a fixing frame 14 is fixed on the top of the flange foot 15, and the push rod motor 10 is installed inside the fixing frame 14. The push rod motor 10 can be fixed to one side of the swivel base 1 through the flange foot 15 to provide stability when the ladder block 13 falls.

[0025] Working principle: The inner ring is sleeved on the outside of the conical piece 7 and is seated on the mold seat 2. When the roller is fed into the retainer and moves up, the push rod motor 10 contracts and drives the pressure plate 11, the support rod 12 and the ladder block 13 to descend. The ladder block 13 can be inserted between the push blocks 4 and squeeze the push blocks 4 outward at the extrusion groove 8. After being squeezed, the push blocks 4 can drive the conical piece 7 to move outward through the support rod 6 and clamp the inner wall of the inner ring. Since they move at the same time and the moving distance is fixed, the inner ring can be clamped, limited and adjusted in position, so that the upward movement of the roller and the retainer can be successfully sleeved on the outside of the inner ring.

[0026] The circuits, electronic components and control modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to software and methods.

[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model.
