Description

Technical Field

[0001] The utility model relates to the technical field of bearing disassembly and assembly, in particular to roller bearing disassembly and assembly equipment. Background Art

[0002] When the roller is in use, it is usually necessary to install bearings at the end, and then fix it to the mechanical equipment through the bearings to achieve functions such as transmission, guidance, and pressure. The bearings play an important role in the operation of the roller. As the use time increases, the bearings will inevitably suffer from problems such as wear and corrosion. Therefore, it is necessary to regularly remove the bearings from the ends of the rollers and inspect or replace the bearings.

[0003] The bearing and the roller shaft fit tightly, and the bearing is installed by knocking, which has high labor costs, low work efficiency, and is easy to damage the bearing. It is more dependent on the proficiency of the operator and is not suitable for large-scale bearing maintenance. The patent document with application number CN201820224972.2 discloses a roller bearing disassembly and assembly equipment, which includes a fixed base with a guide rail, a mobile base connected to the guide rail of the fixed base, and a pressure plate that can be sleeved on the rubber roller shaft. The mobile base is provided with a baffle, and the two sides of the fixed base are provided with clamps; when disassembling the bearing, fix the bearing and apply thrust to the rubber roller through the jack. When installing the bearing, fix the rubber roller and apply thrust to the bearing through the jack. The above technical solution reduces the labor intensity of manpower and improves work efficiency, but mechanical equipment often has a variety of rubber rollers of different specifications, and the lengths of these rubber rollers are different. It is difficult to meet the needs of rapid disassembly and assembly through the above equipment. Summary of the invention

[0004] In order to solve the above problems, the utility model provides a roller bearing disassembly and assembly device, which can adjust and match rollers of different specifications to facilitate the rapid disassembly and assembly of the roller bearings.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A roller bearing disassembly and assembly device comprises a positioning platform, two limit seats arranged at both ends of the positioning platform and a power device arranged toward one of the limit seats; the positioning platform is provided with a sliding guide groove extending in a straight line, and the two ends of the sliding guide groove are respectively directed toward the two limit seats; the limit seat comprises a guide rail, a clamping plate slidably connected to the guide rail and a locking mechanism that can relatively fix the guide rail and the clamping plate, and the clamping plate is provided with a shaft head opening; the power device comprises a driving cylinder, a transmission rod connected to the driving cylinder and a butt joint connected to the transmission rod, the transmission rod can move in a direction perpendicular to the clamping plate, and the butt joint corresponds to the position of the shaft head opening.

[0007] In the utility model, the positioning platform is used to place the roller. After the roller is placed in the sliding guide groove, it can move axially to facilitate the subsequent disassembly of the bearing. The two limit seats arranged on both sides of the positioning platform play a limiting role in the disassembly and installation of the bearing respectively. The limit seat close to the power device is marked as limit seat A, and the other limit seat is marked as limit seat B. The working principle of the utility model is as follows: when disassembling the bearing, the locking mechanism of the limit seat B is released, so that the clamping plate of the limit seat B is in an active state, and the roller can move in the direction of the limit seat B, and the locking mechanism of the limit seat A is activated, so that The card plate of the limit seat A is inserted into the gap between the roller body and the bearing and fixed, and then the power device is started so that the abutment of the power device applies thrust to the shaft head at the end of the roller. Under the restriction of the limit seat A, the bearing and the shaft head are gradually separated to achieve the disassembly of the bearing; when installing the bearing, the card plate is moved so that both ends of the roller body are abutted against the card plate, and the locking mechanism of the limit seat A and the limit seat B is activated to fix the roller axially, and then the bearing is placed at the shaft head of the roller, and thrust is applied to the bearing through the abutment so that the bearing is gradually sleeved onto the shaft head to achieve the installation of the bearing. The utility model can reduce the manpower requirements when installing the bearing, improve work efficiency, reduce the bearing damage rate, and can adjust the position of the card plates in the two limit seats to match rollers of different lengths, which is convenient for batch maintenance of equipment bearings.

[0008] Furthermore, the guide rail includes a guide rod and a fixed base plate, the clamping plate includes a first connecting block slidably connected to the guide rod and a second connecting block fitted with the fixed base plate, the fixed base plate is provided with a strip connecting hole extending axially along the guide rod, and the second connecting block is provided with a bolt positioning hole corresponding to the strip connecting hole.

[0009] Furthermore, the guide rod is sleeved with a pre-compression spring, and the pre-compression spring abuts against a side of the limiting seat away from the positioning platform.

[0010] The pre-compression spring applies elastic force to the clamping plate, so that the clamping plate can naturally abut against the two ends of the roller body, further facilitating the disassembly and assembly of the bearing. It should be noted that the elastic force should be controlled within an appropriate range that can push the roller. If the elastic force is too large, the workload of the power device during the bearing disassembly process will increase.

[0011] Furthermore, the guide rail comprises two guide rods and two fixed base plates, and a sliding cavity for the clamping plate to move is formed between the two fixed base plates.

[0012] Furthermore, the clamping plate includes a bottom plate and a limit plate vertically connected to the bottom plate, and the first connecting block and the second connecting block are fixedly connected to the bottom plate and arranged at the side of the limit plate. The side position here refers to the two sides of the limit plate in the direction perpendicular to the guide rod.

[0013] Furthermore, the limiting plate is arranged at an edge of the bottom plate close to the positioning platform, and the second connecting block is arranged at an edge of the bottom plate away from the positioning platform.

[0014] Furthermore, the clamping plate also includes a reinforcing plate arranged perpendicular to the bottom plate and the limiting plate.

[0015] Furthermore, a height adjustment device is installed at the bottom of the limit seat and the power device.

[0016] Furthermore, the shaft head through opening forms an opening at the upper end of the clamping plate, and the shaft head through opening includes a rectangular notch near the opening position and a circular notch near the bottom position, and the abutment head is aligned with the center of the circular notch.

[0017] Furthermore, the abutment head is detachably connected to the transmission rod.

[0018] In summary, the application of the utility model can achieve the following beneficial effects:

[0019] 1. The utility model disassembles and assembles the roller bearing through a positioning table, a limit seat and a power device, which saves manpower and improves work efficiency compared to the traditional manual disassembly and assembly method.

The base plate 221 is slidably connected to the guide rail 21, and the base plate and the guide rail can be fixed to each other by a locking mechanism, and the extension direction of the guide rail is consistent with the sliding guide groove; the power device 3 includes a driving cylinder 31, a transmission rod 32 controlled by the driving cylinder, and a butt joint 33 detachably connected to the end of the transmission rod, the butt joint corresponds to the position of the shaft head opening, specifically corresponds to the circular notch of the shaft head opening, and the transmission rod can drive the butt joint to move along the axis of the circular notch.

[0028] The working principle of the above embodiment is as follows: when disassembling the bearing, release the locking mechanism of the limit seat B, so that the card plate of the limit seat B is in an active state, and the roller can move in the direction of the limit seat B, activate the locking mechanism of the limit seat A, so that the card plate of the limit seat A is inserted into the gap between the roller body and the bearing and fixed, and then start the power device, so that the abutment of the power device applies a thrust to the shaft head at the end of the roller, and under the restriction of the limit seat A, the bearing and the shaft head are gradually separated to achieve the disassembly of the bearing; when installing the bearing, move the card plate so that both ends of the roller body are abutted against the card plate, activate the locking mechanisms of the limit seat A and the limit seat B, so that the roller is axially fixed, and then place the bearing at the shaft head of the roller, and apply a thrust to the bearing through the abutment, so that the bearing is gradually sleeved on the shaft head to achieve the installation of the bearing. It should be noted that during the disassembly and installation of the bearing, the abutment needs to abut against the shaft head and the bearing respectively, and the structures required for the two steps are different, so the abutment needs to be replaced in a timely manner.
