Technical Field

[0001] The utility model belongs to the technical field of bearing handling, and particularly relates to a heated bearing handling device. Background Art

[0002] At present, during the hot sleeving of bearings in the motor manufacturing process, when handling relatively heavy heated bearings onto the rotating shaft for hot sleeving, at the assembly site, generally one person uses asbestos gloves for protection to handle and then perform hot sleeving after the bearing is heated. However, the current requirement prohibits the use of asbestos during the motor manufacturing process, and the bearings to be assembled are relatively heavy, so it is laborious for one person to handle, with a large labor intensity.

[0003] In the patent document with the publication number CN204507924U, a bearing clamping hot sleeving device is provided. In this patent, a fixed clamping plate and a sliding clamping plate are provided between two parallel handles. The two ends of the fixed clamping plate are respectively fixed on the two handles, and the two ends of the sliding clamping plate are respectively fixed on the handles through wing bolts; the fixed clamping plate and the sliding clamping plate form an arc shape matching the outer circle of the bearing to be clamped.

[0004] However, when using the above patent, it still requires manual holding of the handle and manual lifting of the bearing to move, and two people are needed. When the bearing is large and heavy, it is not easy even for two people to lift the bearing. In addition, when one person's hand slips, accidents are likely to occur. Content of the Utility Model

[0005] In order to solve the problem that the prior art requires manual holding of the handle and manual lifting of the bearing to move, the utility model provides a heated bearing handling device, which can hook the heated bearing through a hook claw, then lift the bearing by a chain hoist, and fix the hook claw through a fixed block to prevent the hook claw from shaking and causing the bearing to fall during the movement of the base, and then drive the bearing to move by pushing the base.

[0006] The technical solution adopted by the heated bearing handling device of the utility model is as follows:

[0007] A heated bearing handling device includes a base. A chain hoist is connected to the base through a column and a bearing plate. The hook of the chain hoist is connected with a plurality of groups of connecting blocks. A group of hook claws that can rotate along the length direction of the base and have opposite inclination directions are arranged at the bottom of each connecting block, and the directions of the hook claws at the bottom of the connecting block face the other connecting block in the same group;

[0008] A group of moving plates that can move along the length direction of the base are also arranged on the base on one side of the column. Fixing blocks for connecting with the connecting blocks are arranged on the opposite sides of the two moving plates.

[0009] A further improvement of the technical solution of the present utility model lies in that one end of the bearing plate is fixedly arranged at the top end of the column, and a connecting hook for connecting a chain block is fixedly connected to the end of the bearing plate far from the column.

[0010] A further improvement of the above technical solution of the present utility model lies in that the hook of the chain block is connected to the connecting hook, and the hook of the chain block is connected to the connecting block through a connecting chain.

[0011] A further improvement of the above technical solution of the present utility model lies in that a chute is opened along the length direction of the base, and sliders corresponding to the two moving plates one by one and fixedly connected thereto are slidably connected in the chute.

[0012] A further improvement of the technical solution of the present utility model lies in that a bidirectional screw rod penetrating through the two sliders is rotatably connected in the chute, and the two sliders are respectively located on both sides of the bidirectional screw rod and are threadedly connected to the bidirectional screw rod.

[0013] A further improvement of the above technical solution of the present utility model lies in that one end of the bidirectional screw rod extends outside the base and is fixedly sleeved with a rotating disc, and a rotating rod perpendicular to the rotating disc is rotatably arranged at the edge of the rotating disc.

[0014] A further improvement of the above technical solution of the present utility model lies in that internal threaded holes parallel to the base are opened on the sides of the fixed blocks far from the corresponding moving plates, and through holes matching the internal threaded holes and parallel to the base are opened on the connecting blocks.

[0015] A further improvement of the above technical solution of the present utility model lies in that a plurality of universal wheels are arranged at the bottom of the base, and a handle for pushing the base is arranged on one side of the base.

[0016] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model includes:

[0017] By arranging the hook claws, the present utility model can hook the bearing to be hot-sleeved; by arranging the chain block, the height of the connecting block and the hook claws can be conveniently adjusted, so as to adjust the height of the bearing; by arranging the handle, the base can be conveniently pushed to move, so as to conveniently move the bearing for heating and hot-sleeving; by arranging the fixed blocks and the connecting block, the hook claws can be fixed, so as to prevent the bearing from falling when the base moves.

[0018] Meanwhile, in the present utility model, since the connecting block is connected to the hook of the chain block through a connecting chain, the worker can conveniently push the connecting block to move the position of the bearing, so as to conveniently perform heating or hot-sleeving operations on the bearing.

[0019] By arranging the threaded rod in the present utility model, the positions of the two moving plates and the corresponding fixed blocks can be adjusted, so as to be applicable to bearings with different diameters.

[0020] In the present utility model, since there are several groups of connecting blocks, the bearing can be hooked more firmly.

[0021] Compared with the prior art where a worker needs to hold the handle manually and move the bearing by lifting it manually, in the present utility model, the only manual operation required is to pull the chain hoist and push the connecting block. Compared with the prior art, only one worker is needed to complete the operation, which can save a large amount of manpower and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In the present utility model, when the clamping mechanism is specifically arranged, reference can be made to Figure 1 and Figure 3 . According to Figure 1 and Figure 3 , it can be known that the clamping mechanism includes a column 2 rotatably connected to the base 1. The top of the column 2 is fixedly connected with a horizontal bearing plate 3. One end of the bearing plate 3 away from the column 2 is connected with a chain block 4. Specifically, a connecting hook 31 is fixedly connected to one end of the bearing plate 3 away from the column 2, and the hook 44 of the chain block 4 is hooked to the connecting hook 31; Continuing to refer to Figure 1 and Figure 3 , the hook 41 of the chain block 4 is connected with a plurality of groups of connecting blocks 42. Specifically, the number of the connecting blocks 42 can be set to one group (as shown in Figure 1 ) or two groups. When two groups of connecting blocks 42 are provided, the arrangement directions of the two groups of connecting blocks 42 are perpendicular to each other. Each group includes two connecting blocks 42. The top of each connecting block 42 is connected to the hook 41 of the chain block 4 through a connecting chain 45, and the bottom of each connecting block 42 is connected with a group of hook claws 43 that can rotate along the length direction of the base 1 and have opposite inclination directions. The hook claws 43 at the bottom of the same group of connecting blocks 42 are arranged facing each other; Continuing to refer to Figure 1 and Figure 3 , each connecting block 42 is provided with a through hole 46 parallel to the base 1.

[0032] In the present utility model, when the fixing mechanism is specifically arranged, reference can be made to Figure 1 and Figure 2 . According to Figure 1 and Figure 2 , it can be known that the fixing mechanism includes a sliding groove 52 opened along the length direction of the base 1 on one side of the column 2. A bidirectional screw 54 is rotatably connected in the sliding groove 52. Both sides of the bidirectional screw 54 are threadedly connected with sliders 53 that can slide in the sliding groove 52. The top of each slider 53 is fixedly connected with a vertically arranged moving plate 5. On the opposite sides of the two moving plates 5, fixing blocks 51 for fixing the connecting blocks 42 are fixedly connected, and each fixing block 51 is provided with an internal threaded hole 57 that cooperates with the through hole 46 of the connecting block 42 and is parallel to the base 1.

[0033] In the present utility model, in order to facilitate driving the bidirectional screw 54 to rotate, continuing to refer to Figure 2 , one end of the bidirectional screw 54 away from the column 2 extends outside the base 1 and is fixedly sleeved with a rotating disc 55. The edge of the rotating disc 55 is rotatably connected with a rotating rod 56 perpendicular to the rotating disc 55.

[0034] Meanwhile, the above-mentioned rotary disk 55 and rotary rod 56 can also be replaced with a stepper motor (not shown in the figure), and the output shaft of the stepper motor is fixedly connected to one end of the bidirectional screw 54 extending outside the base 1.

[0035] The working principle of the heating bearing handling device in this embodiment is as follows: When the present utility model is in use, first, the present utility model is pushed to the side of the bearing to be replaced through the handle. The vertical column 2 is rotated manually to align the hook 43 with the edge of the bearing in the vertical direction. Then, the manual hoist 4 is pulled to lower the connecting block 42 and the hook 43 until the hook 43 can hold the bearing. Then, the worker moves the hook 43 to hold the bearing. Then, the manual hoist 4 is pulled in the reverse direction, so that the connecting block 42, the hook 43, and the bearing move upward. Then, the vertical column 2 is rotated again to rotate the vertical column 2 in the reverse direction to the original position. At this time, the bearing is between the two moving plates 5. Then, the manual hoist 4 is pulled again to align the through hole 46 of the connecting block 42 with the internal thread hole 57 of the fixing block 51. Then, the bidirectional screw 54 is rotated to make the two moving plates 5 move towards each other until the fixing block 51 fits together with the corresponding connecting block 42. At this time, the internal thread hole 57 on the fixing block 51 and the through hole 46 on the corresponding connecting block 42 are communicated, and a screw is screwed into the through hole 46 and the internal thread hole 57, so as to temporarily fix and connect the fixing block 51 and the connecting block 42 together.

[0036] Then, the present utility model is moved again to the position for heating the bearing, and the screw is removed. Then, the bidirectional screw 54 is rotated in the reverse direction to make the two moving plates 5 move in the reverse direction. Then, by rotating the vertical column 2 and pulling the manual hoist 4, the bearing on the hook 43 is moved to the heating position, so as to heat the bearing.

[0037] After the bearing is heated, the bearing on the hook 43 is moved between the two moving plates 5 by rotating the vertical column 2 in the reverse direction and pulling the manual hoist 4, and the two moving plates 5 are moved to temporarily fix and connect the fixing block 51 and the connecting block 42 together again.

[0038] Then, the present utility model is pushed to the side of the position where the bearing needs to be installed through the handle again. The fixing block 51 and the connecting block 42 are separated. Then, by rotating the vertical column 2 and pulling the manual hoist 4, the bearing on the hook 43 is moved to the position where it needs to be installed until the bearing is installed. Then, the hook 43 is removed from the bearing.

[0039] In the above embodiment, the present utility model provides a heating bearing handling device. By setting the hook, the bearing that needs to be hot-fitted can be hooked; by setting the manual hoist, the height of the connecting block and the hook can be conveniently adjusted, so as to adjust the height of the bearing; by setting the handle, the base can be conveniently pushed to move, so as to conveniently move the bearing for heating and hot-fitting; by setting the fixing block and the connecting block, the hook can be fixed, so as to prevent the bearing from falling when the base moves.
