Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a large-scale bearing roller assembly tool. Background Art

[0002] Roller bearings are a type of rolling bearings and are one of the most widely used components in modern machinery. They rely on rolling contact between the main components to support rotating parts. Most roller bearings have been standardized. When assembling existing large roller bearings, after the outer ring is lifted, the inner ring needs to be supported by a jack or bracket, which is inconvenient. Moreover, when the inner ring is turned over from one side to the other after assembly, the outer ring is often rolled on the ground to achieve the purpose of turning the inner ring over. However, large roller bearings are dangerous when rolling and inconvenient to operate. Summary of the invention

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a large-scale bearing roller assembly tool with good assembly effect and low labor intensity.

[0004] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a large-scale bearing roller assembly tool, which includes an assembly unit and a rotation unit that cooperate with each other, and the assembly unit includes a base, a column, a pad, and a retaining frame pad. The base is rectangular, and adjustment grooves are provided on both sides of the length direction of the base. A group of columns are movably installed at each end of the base, a fixed support plate is fixed on the top of the column, and an L-shaped pad is installed on the top of the fixed support plate. The fixed support plate cross arms on the two groups of columns are opposite, and the retaining frame pad is installed on the cross arm of the fixed support plate through a height adjustment bolt.

[0005] The rotating unit includes a rotating support, a support block, and a support shaft, wherein a support shaft is provided at each of the two ends of the top of the rotating support, and the ends of the support shaft are fixed to the rotating support through corresponding support blocks, and bearings greater than 2 are installed on the shaft body of the support shaft.

[0006] The height adjustment bolt passes through the fixed support plate from bottom to top and then engages with the bottom of the retaining frame pad.

[0007] Each group of upright posts comprises two posts which are respectively mounted on corresponding adjusting slide grooves, and the tops of the upright posts are connected and fixed to the two sides of the bottom of the fixed support plate.

[0008] The adjusting slot is convex in vertical section, an adjusting plate is fixed at the bottom of the column, the width of the adjusting plate is greater than the width of the top of the adjusting slot, a slot adjusting screw is arranged on the adjusting plate, the bottom of the slot adjusting screw passes downward through the base and engages with the slot nut in the adjusting slot.

[0009] After the utility model adopts the above scheme, the outer ring of the bearing roller is lifted by an external crane (so that the outer ring and the inner ring form a cross shape when viewed from the side), the two ends of the inner ring are supported by corresponding pad cross arms, the height adjustment bolt is used to adjust the height of the retaining frame pad to facilitate the stability of the inner ring, and the width of the assembly table can also be adjusted by the movement of the slide groove adjusting screw in the adjusting slide groove, and the roller can be installed on the inner ring. Each time a roller is installed, the inner ring is rotated a little angle (lifted and rotated by the crane), so that the assembly position is always located in front of the operator. After assembling one side, the bearing roller is hoisted as a whole to the rotating unit by the crane. At this time, the outer ring is supported by the bearing, and then the crane is released, and the outer ring is rotated 180°, so that the inner ring is rotated 180° synchronously, so that the assembled roller is located below the inner ring (the inner ring without roller assembly is rotated to the top), and then the bearing roller is hoisted as a whole to the assembly unit by the crane for repeated assembly. The bearing roller assembly effect after adopting this scheme is good and the labor intensity is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention is further described below in conjunction with all the accompanying drawings. The preferred embodiments of the present invention are as follows: Figure 1 To Attachment Figure 4The large-scale bearing roller assembly tool described in this embodiment includes an assembly unit and a rotation unit that cooperate with each other. The assembly unit includes a base 1, a column 2, a pad 3, and a retainer pad 4. The base 1 is rectangular, and adjustment slots 9 are provided on both sides of the length direction of the base 1. A group of columns 2 are movably installed at each end of the base 1. A fixed support plate 11 is fixed on the top of the column 2. An L-shaped pad 3 is installed on the top of the fixed support plate 11. The cross arms of the fixed support plates 11 on the two groups of columns 2 are opposite, and the retainer pad 4 is installed on the cross arms of the fixed support plates 11 through height adjustment bolts 5. The height adjustment bolt 5 passes through the fixed support plate 11 from bottom to top and then engages with the bottom of the retainer pad 4. Each group of columns 2 is two, which are respectively installed on the corresponding adjustment slots 9, and the top of the column 2 is connected and fixed to both sides of the bottom of the fixed support plate 11. The adjusting slot 9 is convex in vertical cross section, an adjusting plate 10 is fixed at the bottom of the column 2, the width of the adjusting plate 10 is greater than the width of the top of the adjusting slot 9, a slot adjusting screw 7 is provided on the adjusting plate 10, and the bottom of the slot adjusting screw 7 passes downward through the base 1 and is meshed with the slot nut 8 in the adjusting slot 9.

[0015] The rotating unit includes a rotating support 12, a support block 13, and a support shaft 14, wherein a support shaft 14 is provided at each of the two ends of the top of the rotating support 12, and the ends of the support shaft 14 are fixed to the rotating support 12 through corresponding support blocks 13, and bearings 15 greater than 2 are installed on the shaft body of the support shaft 14.

[0016] After adopting the above scheme in this embodiment, the outer ring of the bearing roller is lifted by an external crane (so that the outer ring and the inner ring form a cross shape when viewed from the side), and the two ends of the inner ring are supported by corresponding pad cross arms. The height adjustment bolt is used to adjust the height of the retaining frame pad to facilitate the stability of the inner ring. The width of the assembly table can also be adjusted by the movement of the slide groove adjusting screw in the adjusting slide groove, so that the roller can be installed on the inner ring. Each time a roller is installed, the inner ring is rotated a little angle (lifted and rotated by the crane), so that the assembly position is always in front of the operator. After assembling one side, the bearing roller is hoisted as a whole to the rotating unit by the crane. At this time, the outer ring is supported by the bearing, and then the crane is released, and the outer ring is rotated 180°, so that the inner ring is rotated 180° synchronously, so that the assembled roller is located below the inner ring (the inner ring without roller assembly is rotated to the top), and then the bearing roller is hoisted as a whole to the assembly unit by the crane for repeated assembly. The bearing roller assembly effect after adopting this scheme is good and the labor intensity is low.
