Description

Technical Field

[0001] The utility model relates to the technical field of installation tools, in particular to an axial installation tool for a bearing sealing ring. Background Art

[0002] Bearings, also known as bearings, are mechanical parts that support rotating shafts. When processing and assembling bearings, it is necessary to install a sealing ring shaft on the bearing to keep the inside of the bearing in a sealed state later. When installing the sealing ring shaft on the bearing, an installation tool is required to ensure the accuracy of the installation position of the sealing ring shaft and the bearing. In daily use, a bearing sealing ring axial installation tool is required to install the sealing ring shaft.

[0003] The existing installation tooling is often used in a fixed installation mode, which is not convenient for adjusting the installation height position of the device according to the use requirements, reducing the adjustability of the device installation. The existing solution is to equip electrical equipment such as threaded feet and electric rods to adjust the installation height position of the device. However, when the device is used, it does not have the function of improving the sealing performance of the sealing ring shaft installation operation, and cannot clean the dust and impurities floating inside the bearing, resulting in a gap at the joint between the sealing ring shaft and the bearing, which also increases the difficulty of cleaning the narrow space inside the bearing. At the same time, it does not have the function of safely protecting the bearing. Pressure docking is often used when installing the bearing and the sealing ring shaft. Excessive pressure can easily cause the bearing to deform under force, and too little pressure can cause the bearing and the sealing ring shaft to be loosely connected, thereby reducing the quality of the subsequent bearing. Therefore, it is necessary to design a bearing sealing ring axial installation tool. Utility Model Content

[0004] The utility model aims to provide a bearing sealing ring axial installation tool to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an axial installation tool for a bearing sealing ring, comprising a box body, a driving mechanism and a cleaning mechanism, a driving mechanism movably installed on one side of the box body, the driving mechanism comprising a moving box, a servo motor is fixedly installed inside the moving box, a gear plate is fixedly installed on the output end of the servo motor, a linkage rod is fixedly installed on the top of the moving box, a pressure sensor is fixedly installed on the bottom end of the linkage rod, a hollow pressure holding seat is fixedly installed on the bottom of the pressure sensor, a cleaning mechanism is fixedly installed on the other side of the box body, the cleaning mechanism comprises an air pump, a telescopic tube is fixedly installed on one side of the air pump, a plurality of spray discs are equidistantly installed on the bottom of the hollow pressure holding seat, and the top of the spray disc is connected to one side of the telescopic tube through a pipe fitting, and a filter box is fixedly installed on the other side of the air pump through a pipe fitting.

[0006] The servo motor is powered on to drive the toothed disc to rotate, and the rotating toothed disc drives the moving box to move vertically through the meshing rack. The vertically moving box can drive the pressure sensor through the linkage rod to apply pressure to the hollow pressing seat, and the hollow pressing seat that is pressed down can facilitate the pressing and docking operation of the bearing and the sealing ring shaft. The pressure sensor is powered on and used in conjunction with the controller to intelligently control the servo motor to stop running, thereby stopping the hollow pressing seat from applying pressure to the bearing and the sealing ring shaft.

[0007] Preferably, a first inlet is fixedly installed at the bottom of the box body near the cleaning mechanism, and a second inlet is fixedly installed below the first inlet. The sealing ring shaft and the bearing can be easily put into the box body through the second inlet and the first inlet, providing a source of materials for the subsequent pressing and docking operation of the bearing and the sealing ring shaft.

[0008] Preferably, a rack is fixedly installed on one side of the box away from the cleaning mechanism, and one side of the rack is meshed with a toothed disc. The rack can provide an installation position for the mobile box, and the toothed disc and the rack can be used together to facilitate the subsequent vertical displacement of the mobile box.

[0009] Preferably, two sets of filter plates are fixedly installed inside the filter box, and an air inlet is fixedly installed at the bottom of the filter box. The filter plates can be used to filter the air inside the filter box, thereby preventing the air containing dust and impurities inside the filter box from being transported to the inside of the bearing, and also ensuring the cleanliness of the inside of the bearing.

[0010] Preferably, a constant speed motor is fixedly mounted at the bottom of the front of the box, and a valve plate embedded in the box is fixedly mounted at the output end of the constant speed motor. The valve plate is driven to rotate by the constant speed motor, and the valve plate rotates to an inclined state, so that the device is suitable for unattended scenes, and no operator is required to manually unload the material.

[0011] Preferably, a workbench is fixedly installed at the bottom of the box, and a limiting groove is provided inside the workbench. The workbench can facilitate the subsequent processing of the bearing, and the bearing can fall into the workbench through the inclined surface of the limiting groove for fixation, thereby avoiding the movement of the bearing when the bearing is pressed and held later, and limiting the movement of the bearing.

[0012] Preferably, a controller is fixedly mounted on the top of the front of the box, and an inspection door is movably mounted below the controller through hinges. The controller facilitates subsequent operators to intelligently control the power-on operation of the electrical equipment inside the device, and also facilitates maintenance work on the electrical equipment inside the device.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The controller controls the air pump through the wire to generate suction and transport the outside air to the filter box for filtering. The impurities in the air can be filtered through the filter plate, and the filtered air can be transported to the spray plate through the telescopic pipe through the pipe fitting. The airflow can be evenly transported to the bearing surface through the spray plate, so as to achieve the purpose of wind cleaning of the bearing surface and improve the sealing performance of the sealing ring shaft installation operation, which is convenient for cleaning the dust and impurities falling inside the bearing, avoiding the gap between the sealing ring shaft and the bearing, and reducing the difficulty of cleaning the narrow space inside the bearing.

[0015] 2. The servo motor is powered on to drive the toothed disc to rotate, and the rotating toothed disc drives the moving box to move vertically through the meshing rack. The vertically moving box can drive the pressure sensor through the linkage rod to apply pressure to the hollow pressing seat. The hollow pressing seat that presses down can facilitate the pressing and docking operation of the bearing and the sealing ring shaft. The pressure sensor is powered on and used in conjunction with the controller to intelligently control the servo motor to stop running, thereby stopping the hollow pressing seat from applying pressure to the bearing and the sealing ring shaft, realizing the function of safety protection for the bearing, solving the problem that excessive pressure during pressure-type docking easily causes deformation of the bearing under force, and avoiding the problem that too small pressure causes the bearing and the sealing ring shaft to be loosely docked, thereby ensuring the quality of the subsequent processing of the bearing.

DETAILED DESCRIPTION

[0021] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Embodiment 1

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the utility model proposes an axial installation tool for a bearing sealing ring, comprising a box body 1, a driving mechanism 2 and a cleaning mechanism 3. The driving mechanism 2 is movably installed on one side of the box body 1. The driving mechanism 2 comprises a moving box 201. A servo motor 202 is fixedly installed inside the moving box 201. A toothed disc 203 is fixedly installed at the output end of the servo motor 202. A linkage rod 204 is fixedly installed on the top of the moving box 201.

[0024] A pressure sensor 205 is fixedly installed at the bottom end of the linkage rod 204, a hollow pressure holding seat 206 is fixedly installed at the bottom of the pressure sensor 205, a rack 207 is fixedly installed on the side of the box body 1 away from the cleaning mechanism 3, and one side of the rack 207 is meshed and connected with the toothed disc 203, and a cleaning mechanism 3 is fixedly installed on the other side of the box body 1, and the cleaning mechanism 3 includes an air pump 301, and a telescopic tube 302 is fixedly installed on one side of the air pump 301. A plurality of spray discs 303 are equidistantly installed at the bottom of the hollow pressure holding seat 206, and the top of the spray disc 303 is connected to one side of the telescopic tube 302 through a pipe fitting, and a filter box 304 is fixedly installed on the other side of the air pump 301 through a pipe fitting;

[0025] A uniform speed motor 4 is fixedly installed at the bottom of the front side of the box body 1, and a valve plate 401 embedded in the box body 1 is fixedly installed at the output end of the uniform speed motor 4; a workbench 5 is fixedly installed at the bottom of the box body 1, and a limiting groove 501 is provided inside the workbench 5; a controller 6 is fixedly installed at the top of the front side of the box body 1, and an inspection door 7 is movably installed below the controller 6 through a hinge.

[0026] The working principle of the axial installation tooling for the bearing seal ring based on the first embodiment is: after the box body 1 is installed to the specified installation position, the operator manually rotates the threaded foot rod at the bottom of the box body 1 to adjust the installation height of the box body 1, and then the seal ring shaft and the bearing are placed into the box body 1 through the first inlet 101 and the second inlet 102;

[0027] The special bell-mouth structure of the limiting groove 501 can facilitate the movement position restriction of the bearing put into the box body 1, and the bearing is allowed to fall into the inside of the workbench 5 through the inclined surface of the limiting groove 501 to be fixed, realizing the function of non-powered restriction of the movement position of the bearing and the sealing ring shaft, and facilitating the subsequent pressing of the sealing ring shaft into the inside of the bearing;

[0028] The air pump 301 is powered on and operated by the controller 6 to generate suction and deliver external air to the inside of the filter box 304, and the dust and impurities carried in the air can be filtered through the filter plate 305, and the filtered air can be delivered to the inside of the telescopic tube 302 through the pipe fitting, and then the high-pressure airflow can be delivered to the inside of the spray disc 303 through the telescopic tube 302, and the high-pressure airflow can be evenly delivered to the bearing surface through the spray disc 303, so as to achieve the purpose of wind cleaning the bearing surface, avoid the gap between the sealing ring shaft and the bearing, and realize the function of improving the sealing performance of the sealing ring shaft installation operation;

[0029] The controller 6 controls the servo motor 202 to be powered on and run, which can drive the toothed disc 203 to rotate. The rotating toothed disc 203 drives the moving box 201 to move vertically through the meshing rack 207. The moving box 201 that moves vertically can drive the linkage rod 204 to move vertically. The linkage rod 204 that moves vertically can drive the hollow pressing seat 206 to press and dock the bearing and the sealing ring shaft inside the box body 1 through the pressure sensor 205, thereby realizing the function of docking the bearing and the sealing ring shaft;

[0030] Then, the pressure applied by the linkage rod 204 to the hollow pressure holder 206 can be monitored in real time by energizing the pressure sensor 205, and the monitoring electromagnetic signal is transmitted to the controller 6 through the wire for calculation. When the controller 6 calculates that the monitoring electromagnetic signal is greater than the preset value, the servo motor 202 is energized and stopped through the wire, thereby realizing the function of safety protection for the bearing, solving the problem that the bearing is easily deformed due to excessive pressure when using pressure docking, and ensuring the quality of the bearing processed in the subsequent process;

[0031] When the docking operation is completed, the controller 6 controls the uniform speed motor 4 to be powered on and drive the valve plate 401 to rotate to an inclined state, so as to facilitate automatic unloading of the bearings after the docking operation inside the box 1. There is no need for operators to monitor the operation of the device, which increases the automation effect of the device.

[0034] In this embodiment, Figure 1 , Figure 2 As shown, the bearing to be connected can be placed into the box body 1 through the second inlet 102, so that the bearing connection position can be limited by the limiting groove 501 later, and the sealing ring shaft can be placed into the box body 1 through the first inlet 101;

[0035] like Figure 3 As shown, the filter plate 305 can be used to filter the air inside the filter box 304, thereby preventing the air containing dust and impurities inside the filter box 304 from being transported to the inside of the bearing, causing secondary contamination of the bearing.
