Description

Technical Field

[0001] The utility model relates to the field of bearing installation, in particular to a bearing pre-positioning mechanism in an oil seal assembly machine. Background Technique

[0002] Existing motors generally include end covers, barrels, and rotating shafts disposed within the barrels. Among them, the end covers are fixedly connected to the barrels; the end covers are generally disc-shaped, and a tube body for the rotating shaft to pass through is formed at the central position. One end of the tube body is connected to the rotating shaft through a bearing, and the other end of the tube body and the rotating shaft are sealed through an oil seal. During motor assembly and manufacturing, generally, the bearing, oil seal, and end cover are first assembled into a whole, and then the rotating shaft and the end cover are connected.

[0003] Currently, the assembly of the end cover, bearing, and oil seal is completed in two steps: 1. Assemble the oil seal and the end cover to form a combined body; 2. Assemble the combined body and the bearing. Among them, when the bearing is installed, it is necessary to first manually take the bearing to the workbench and then use a fixture to lock and position the bearing. The whole operation is relatively cumbersome, the degree of automation is low, and it is difficult to meet the needs of industrial production. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantage of low automation in the existing technology, and to propose a bearing pre-positioning mechanism in an oil seal assembly machine.

[0005] In order to solve the problems existing in the existing technology, the utility model adopts the following technical solutions:

[0006] A bearing pre-positioning mechanism in an oil seal assembly machine includes a bearing plate, on which a pair of rotating plates are rotatably arranged. A pair of transmission rods are rotatably arranged on the bearing plate. Connecting rods are rotatably arranged on the transmission rods, and the connecting rods are rotatably connected to the rotating plates. A pair of fixing blocks are fixedly arranged on the bearing plate. An expansion cylinder is rotatably arranged between the pair of fixing blocks. A round rod is rotatably arranged at the piston rod end of the expansion cylinder, and the round rod is fixedly connected to the pair of transmission rods. A fixing plate is fixedly arranged on the pair of connecting rods, a grasping mechanism is arranged on one side of the fixing plate, and a pair of support rods are fixedly arranged on the bearing plate.

[0007] Preferably, the grasping mechanism includes a grasping cylinder, which is fixedly connected to the fixing plate. A movable plate is fixedly arranged at the piston rod end of the grasping cylinder. A round groove is formed on the movable plate, and an electromagnetic block is fixedly arranged in the round groove.

[0008] Preferably, a placing table is arranged on one side of the bearing plate. A fixing frame is fixedly arranged on the placing table, and a plurality of bearing bodies are movably arranged on the fixing frame.

[0009] Preferably, a detector is fixedly arranged on the placing table, and a pushing frame is slidably arranged on the placing table.

[0010] Preferably, a workbench is provided below the bearing plate, and a pair of clamping cylinders are fixedly arranged on the workbench, and clamping plates are fixedly arranged at the piston rod ends of the clamping cylinders.

[0011] Preferably, an end cover is provided on the workbench, and an oil seal is clamped in the shaft hole of the end cover.

[0012] Preferably, a limiting cylinder is fixedly arranged in the workbench, and a limiting block is fixedly arranged at the piston rod end of the limiting cylinder, and the limiting block is located in the shaft hole of the end cover.

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

[0014] 1. In the present utility model, the transmission rod drives the rotating plate to swing through the connecting rod, and the transmission rod drives the fixed plate to swing. When the fixed plate moves to a position perpendicular to the bearing plate, the grasping cylinder drives the movable plate to move towards the bearing body, the electromagnetic block is electrified, and the electromagnetic block sucks a bearing body into the circular groove. Then the telescopic cylinder drives the round rod to move through the telescopic piston rod end. Furthermore, when the fixed plate moves to a position parallel to the bearing plate, the electromagnetic block is powered off, and the bearing body falls on the limiting block. As the bearing body falls, the bearing body is located directly above the oil seal, and the limiting block limits the bearing body at a predetermined position. The whole operation has a high degree of automation, reduces manual participation, and meets the requirements of industrial production;

[0015] 2. In the present utility model, the detector detects the bearing body at the front end of the fixed frame. When it is found that the bearing body is taken away, the pushing frame will push a plurality of bearing bodies a certain distance towards the detector side to ensure that the electromagnetic block can still take away the bearing body next time, further improving the automation of the device.

A detector 4 is fixedly arranged on the object placing table 3. A pushing frame 41 is slidably arranged on the object placing table 3;

[0027] The telescopic cylinder 15 drives the round rod 16 to move through the telescopic piston rod end. The round rod 16 drives the transmission rod 12 to swing. The transmission rod 12 drives the rotating plate 11 to swing through the connecting rod 13, and the transmission rod 12 drives the fixed plate 17 to swing. When the fixed plate 17 moves to a position perpendicular to the bearing plate 1, the grasping cylinder 2 extends the piston rod, and the piston rod drives the movable plate 21 to move towards the bearing body 32 on the placing table 3. The electromagnet 23 is energized, and the electromagnet 23 sucks a bearing body 32 into the circular groove 22. Then the telescopic cylinder 15 drives the round rod 16 to move through the telescopic piston rod end again, and when the fixed plate 17 moves to a position parallel to the bearing plate 1, it stops. Among them, the detector 4 detects the bearing body 32 at the forefront of the fixed frame 31. When it is found that the bearing body 32 has been taken away, the pushing frame 41 will push a plurality of bearing bodies 32 a certain distance towards the detector 4 side to ensure that the electromagnet 23 can still take away the bearing body 32 next time;

[0028] Embodiment 2: On the basis of Embodiment 1, this embodiment further includes:

[0029] In the specific implementation process, as Figure 5 and Figure 6 shown, a workbench 5 is provided below the bearing plate 1. A pair of clamping cylinders 51 are fixedly provided on the workbench 5. The piston rod ends of the clamping cylinders 51 are fixedly provided with clamping plates 52.

The piston rod end of the limit cylinder 7 is fixedly provided with a limit block 71, and the limit block 71 is located in the shaft hole of the end cover 6;

[0030] Place the end cover 6 on the workbench 5. The clamping cylinder 51 drives the clamping plate 52 to fix the end cover 6. The electromagnet 23 is powered off, and the bearing body 32 falls and is sleeved on the limit block 71. The limit block 71 is small at the top and large at the bottom. As the bearing body 32 falls, the bearing body 32 is located directly above the oil seal 61, and the limit block 71 limits the bearing body 32 at a predetermined position. When pressing the bearing body 32, the limit cylinder 7 drives the limit block 71 to contract into the workbench 5.

[0031] Specifically, the working principle and operation method of the present invention are as follows:

[0032] Step 1, place the end cover 6 on the workbench 5, and the clamping cylinder 51 drives the clamping plate 52 to fix the end cover 6;

[0033] Step 2: The telescopic cylinder 15 drives the round rod 16 to move through the telescopic piston rod end. The round rod 16 drives the transmission rod 12 to swing. The transmission rod 12 drives the rotating plate 11 to swing through the connecting rod 13, and the transmission rod 12 drives the fixed plate 17 to swing. When the fixed plate 17 moves to a position perpendicular to the bearing plate 1, the grasping cylinder 2 extends its piston rod, and the piston rod drives the movable plate 21 to move towards the bearing body 32 on the placing table 3.

[0034] Step 3: The electromagnet 23 is powered on. The electromagnet 23 sucks a bearing body 32 into the round groove 22. Then the telescopic cylinder 15 drives the round rod 16 to move through the telescopic piston rod end, and when the fixed plate 17 moves to a position parallel to the bearing plate 1, it stops.

[0035] Step 4: The detector 4 detects the bearing body 32 at the forefront of the fixed frame 31. When it is found that the bearing body 32 has been taken away, the pushing frame 41 will push a plurality of bearing bodies 32 a certain distance towards the detector 4 side to ensure that the electromagnet 23 can still take away the bearing body 32 next time.

[0036] Step 5: The electromagnet 23 is powered off, and the bearing body 32 falls and is sleeved on the limiting block 71. The upper part of the limiting block 71 is small and the lower part is large. As the bearing body 32 falls, the bearing body 32 is located directly above the oil seal 61. The limiting block 71 limits the bearing body 32 at a predetermined position.
