Description

Technical Field

[0001] This utility model relates to the field of bearing assembly tooling technology, specifically a dustproof assembly tooling for spherical plain bearings. Background Technology

[0002] Spherical plain bearing assembly fixtures are specialized auxiliary devices designed for the efficient and precise assembly of spherical plain bearings. Through standardized positioning structures, clamping mechanisms, and force application components, they can standardize the assembly process, control the coaxiality error between the shaft and the bearing housing, reduce the labor intensity of operators, ensure that the spherical plain bearings are not damaged by bumps during assembly, and improve the assembly quality and production efficiency of the assembly process. When assembling bearings using existing spherical plain bearing assembly fixtures, if dust particles become embedded between the inner and outer rings of the bearing, it will affect the radial / axial clearance of the bearing, leading to problems such as jamming or abnormal noise. At the same time, if the assembly pressure of the spherical plain bearing assembly fixtures is not precisely controlled, it will cause damage to the bearing raceway or deformation of the cage.

[0003] Therefore, a dustproof assembly tooling for spherical bearings is needed to improve the above-mentioned problems. Utility Model Content

A clamping assembly is installed on the outer wall of the equipment cabinet. A pressing assembly is installed on one side of the clamping assembly and on the outer wall of the equipment cabinet. An electrically controlled rotating base is installed on one side of the pressing assembly and on the outer wall of the equipment cabinet. A material unloading gripper is installed on the outer wall of the electrically controlled rotating base. A dustproof assembly is installed on the top outer wall of the equipment cabinet.

[0006] As a preferred embodiment of this utility model, the clamping assembly includes a horizontal servo module, which is installed on the outer wall of the equipment cabinet. An installation plate is installed on the outer wall of the horizontal servo module, and an electrically controlled cylinder is installed on the side wall of the installation plate. Limiting slide rails are symmetrically arranged on the outer wall of the installation plate. A limiting plate is slidably connected to the outer wall of the limiting slide rails. One end of the electrically controlled cylinder is connected to the outer wall of the limiting plate, and a feeding gripper is installed on the outer wall of the limiting plate.

[0007] As a preferred embodiment of this utility model, the pressing component includes a fixed support column and a mounting base. Two sets of fixed supports are provided and are respectively located on the outer wall of the equipment cabinet. A positioning plate is installed on the top outer wall of the fixed support column. An electrically controlled pressing cylinder is embedded in the outer wall of the positioning plate. A pressing plate is slidably connected to the outer wall of the fixed support column.

[0008] As a preferred embodiment of this utility model, an electrically controlled pressing cylinder is connected to the outer wall of the lower pressure plate, a pressing rod is installed on the bottom outer wall of the lower pressure plate, the mounting base is installed on the outer wall of the equipment cabinet, a limit post is installed on the outer wall of the mounting base, and an assembly base plate is slidably connected to the outer wall of the limit post.

[0009] As a preferred embodiment of this utility model, an electrically controlled upward push cylinder is embedded in one side of the limiting post and on the outer wall of the mounting base. One end of the electrically controlled upward push cylinder is connected to an assembly base plate. A pressure sensor is embedded in the outer wall of the assembly base plate, wherein the assembly base plate is located directly below the lower pressure plate.

[0010] As a preferred embodiment of this utility model, the dustproof component includes a dustproof shell, which is installed on the outer wall of the equipment cabinet. A feeding shell is embedded in the bottom outer wall of the dustproof shell. A baffle is installed at the port of the feeding shell via a hinge. Feed slots are symmetrically opened in the inner cavity of the feeding shell and on the outer wall of the dustproof shell.

[0011] As a preferred embodiment of this utility model, an installation groove is provided on the side wall of the dustproof shell, wherein the installation groove is located on one side of the electrically controlled rotating base, and a ventilation fan is installed on the outer wall opposite to the installation groove. An air purifier is embedded in the outer wall of the dustproof shell, wherein the air outlet of the air purifier is connected to the air inlet of the ventilation fan.

[0012] As a preferred embodiment of this utility model, one end of the bearing feeder is connected to the inner wall of the feeding trough. The control panel is connected to the bearing feeder, the electrically controlled rotating base, the unloading gripper, the horizontal servo module, the electrically controlled cylinder, the feeding gripper, the electrically controlled pressing cylinder, the electrically controlled pushing cylinder, the pressure sensor, the ventilation fan, and the air purifier via wires, and the connection method is electrical connection.

[0013] Compared with existing technologies, this utility model achieves dust protection for the dustproof housing by setting a dustproof component in the dustproof assembly tooling for spherical bearings. The air purifier and ventilation fan are controlled by the control panel. Since the ventilation fans are located on the opposite outer walls of the mounting slot, when the ventilation fans are running, one set of ventilation fans exhausts air downwards, while the other set of ventilation fans draws air outwards. The two sets of ventilation fans form an airflow, which prevents external dust from entering the inner cavity of the dustproof housing. At the same time, the ventilation fans draw out the purified air from the air purifier, thereby preventing dust from entering the assembly process. This solves the problem that if dust particles are embedded between the inner and outer rings of the bearing during bearing assembly, it will affect the radial / axial clearance of the bearing, causing jamming or abnormal noise.

[0014] This invention achieves adjustable bearing assembly pressure by incorporating a pressing component in the dustproof assembly fixture for spherical plain bearings. The control panel operates an electrically controlled pressing cylinder, which applies a downward pushing force to a pressing plate. This causes the pressing plate to move downwards on the outer wall of the fixed support, thereby pressing the bearing down onto the pressing rod. Simultaneously, a pressure sensor generates an electrical signal, which is transmitted through wires to the control panel to display the pressure value. The control panel also controls an electrically controlled pushing cylinder, which pushes the assembly base plate upwards, subjecting the bearing to pressure from both sides. Alternatively, if the downward pressure from the pressing plate is excessive, the pushing cylinder moves the assembly base plate downwards to reduce the pressure on the bearing. The pressing component adjusts according to the bearing pressure, thus solving the problem of inaccurate pressure control in the spherical plain bearing assembly fixture, which can lead to bearing raceway damage or cage deformation.

[0019] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 and Figure 5 The clamping assembly 5 includes a horizontal servo module 501, which is mounted on the outer wall of the equipment cabinet 1. A mounting plate 502 is mounted on the outer wall of the horizontal servo module 501. An electric cylinder 503 is mounted on the side wall of the mounting plate 502. Limiting slide rails 504 are symmetrically arranged on the outer wall of the mounting plate 502. A limiting plate 505 is slidably connected to the outer wall of the limiting slide rails 504. One end of the electric cylinder 503 is connected to the outer wall of the limiting plate 505. A feeding gripper 506 is mounted on the outer wall of the limiting plate 505.

[0020] In this embodiment, specific references Figure 1 , Figure 2 and Figure 4 The pressing assembly 6 includes a fixed support column 601 and a mounting base 602. Two sets of fixed supports 601 are provided and located on the outer wall of the equipment cabinet 1. A positioning plate 603 is installed on the top outer wall of the fixed support column 601. An electrically controlled pressing cylinder 604 is embedded in the outer wall of the positioning plate 603. A pressing plate 605 is slidably connected to the outer wall of the fixed support column 601. The electrically controlled pressing cylinder 604 is connected to the outer wall of the pressing plate 605. A pressing rod 606 is installed on the bottom outer wall of the pressing plate 605. The base 602 is installed on the outer wall of the equipment cabinet 1. A limit post 607 is installed on the outer wall of the base 602.

The assembly base plate 608 is located directly below the lower pressure plate 605.

[0021] In this embodiment, specific references Figure 1 , Figure 2 and Figure 3 The dustproof component 9 includes a dustproof housing 901, which is installed on the outer wall of the equipment cabinet 1. A feeding housing 902 is embedded in the bottom outer wall of the dustproof housing 901. A baffle 903 is installed at the port of the feeding housing 902 via a hinge. Feeding slots 904 are symmetrically opened in the inner cavity of the feeding housing 902 and on the outer wall of the dustproof housing 901. An installation slot 905 is opened on the side wall of the dustproof housing 901, which is located on one side of the electrically controlled rotating base 7. A ventilation fan 906 is installed on the opposite outer wall of the installation slot 905. An air purifier 907 is embedded in the outer wall of the dustproof housing 901, and the air outlet of the air purifier 907 is connected to the air inlet of the ventilation fan 906.

[0022] Based on the above structural features and connection relationships, the lower pressure plate 605 moves downward on the outer wall of the fixed support column 601, thereby causing the lower pressure plate 605 to drive the lower pressure rod 606 to press down and assemble the bearing. At the same time, a pressure sensor 610 is provided on the outer wall of the assembly base plate 608. When the bearing is subjected to extrusion force for assembly, after the bearing is assembled, the control panel 3 will control the electric rotating base 7 to operate, so that one end of the electric rotating base 7 will drive the unloading claw 8 to move to a suitable position. When the set parameters are reached, the unloading claw 8 will clamp the bearing. Then the electric rotating base 7 will drive the unloading claw 8 to move in the opposite direction, thereby unloading the bearing. One end of the bearing feeder 4 is connected to the inner wall of the feed trough 904. The control panel 3 is connected to the bearing feeder 4, the electrically controlled rotating base 7, the unloading gripper 8, the horizontal servo module 501, the electrically controlled cylinder 503, the feeding gripper 506, the electrically controlled pressing cylinder 604, the electrically controlled pushing cylinder 609, the pressure sensor 610, the ventilation fan 906, and the air purifier 907 via wires. The electrical connection enables the device to be powered on, thereby allowing the control panel 3 to control the operation of the bearing feeder 4, the electrically controlled rotating base 7, the unloading gripper 8, the horizontal servo module 501, the electrically controlled cylinder 503, the feeding gripper 506, the electrically controlled pressing cylinder 604, the electrically controlled pushing cylinder 609, the pressure sensor 610, the ventilation fan 906, and the air purifier 907.

[0023] When the dustproof assembly fixture for spherical bearings in this solution is in operation, the control panel 3 is connected via wires to the bearing feeder 4, electrically controlled rotating base 7, unloading gripper 8, horizontal servo module 501, electrically controlled cylinder 503, feeding gripper 506, electrically controlled pressing cylinder 604, electrically controlled pushing cylinder 609, pressure sensor 610, ventilation fan 906, and air purifier 907. This electrical connection powers the device, which in turn enables the control panel 3 to control the operation of the bearing feeder 4, electrically controlled rotating base 7, unloading gripper 8, horizontal servo module 501, electrically controlled cylinder 503, feeding gripper 506, electrically controlled pressing cylinder 604, electrically controlled pushing cylinder 609, pressure sensor 610, ventilation fan 906, and air purifier 907. By opening the control panel 3, the air purifier 907 and the ventilation fan 906 are operated. Since the ventilation fans 906 are located on the opposite outer walls of the mounting slot 905, when the ventilation fans 906 are operating, one set of ventilation fans 906 exhausts air downwards, while the other set of ventilation fans 906 draws air outwards. The two sets of ventilation fans 906 form an airflow, which prevents external dust from entering the inner cavity of the dustproof housing 901. At the same time, the ventilation fans 906 draw out the purified air from the air purifier 907, thereby preventing dust from entering the assembly process. This solves the problem that if dust particles are embedded between the inner and outer rings of the bearing during bearing assembly, it will affect the radial / axial clearance of the bearing, causing jamming or abnormal noise. The control panel 3 controls the operation of the bearing feeder 4 to feed the bearings sequentially. At the same time, the control panel 3 controls the operation of the clamping assembly 5, which causes the horizontal servo module 501 to drive the mounting plate 502 to move laterally. The mounting plate 502 then moves laterally via the limit slide rail 504 and the limit plate 505. This causes the limit plate 505 to move the feeding gripper 506. When the device moves to one side of the bearing feeder 4, the control panel 3 controls the operation of the electric cylinder 503, which pushes the limit plate 505 to one side on the outer wall of the limit slide rail 504. This causes the feeding gripper 506 to clamp the outer ring and inner ring of the bearing sequentially. Then, the clamping assembly 5 places the outer ring and inner ring of the bearing sequentially on the assembly base plate 608. The control panel 3 controls the operation of the electrically controlled pressing cylinder 604, causing one end of the cylinder 604 to apply a downward pushing force to the pressing plate 605. This causes the pressing plate 605 to move downwards on the outer wall of the fixed support 601, thereby driving the pressing rod 606 to press down and assemble the bearing. Simultaneously, a pressure sensor 610 is installed on the outer wall of the assembly base plate 608. When the bearing is subjected to compressive force, the pressure sensor 610 generates an electrical signal, which is transmitted to the control panel 3 via wires, allowing the control panel 3 to display the pressure in real time. The control panel 3 controls the operation of the electrically controlled push cylinder 609, so that one end of the electrically controlled push cylinder 609 pushes the mounting base plate 608 upward, so that the bearing is subjected to the squeezing force from both sides at the same time. Or, when the downward pressure of the pressure plate 605 is too large, one end of the electrically controlled push cylinder 609 drives the mounting base plate 608 downward to reduce the pressure on the bearing. The pressure-lowering component 6 can be adjusted according to the pressure of the bearing, thereby solving the problem that the assembly pressure of the spherical plain bearing assembly tooling is not accurately controlled, which may lead to damage to the bearing raceway or deformation of the cage.

[0024] The bearing feeder 4, electrically controlled rotating base 7, unloading gripper 8, horizontal servo module 501, electrically controlled cylinder 503, feeding gripper 506, electrically controlled pressing cylinder 604, electrically controlled pushing cylinder 609, pressure sensor 610, ventilation fan 906, air purifier 907, and control panel 3 used in this utility model are all existing known electrical devices, and all can be directly purchased and used on the market.
