The PLC controller controls the bearing loading assembly 2, the installation shaft loading assembly 3, the material picking assembly 4 and the pressing device 5 to suspend work, thereby preventing the staff from accidentally extending their limbs or body parts into the inside of the observation window 101 and causing danger.

[0097] Specifically, in this embodiment, the PLC controller can be an S7-200 ultra-miniaturized PLC controller, and the sensor 1 312, the sensor 2 5107 and the sensor 3 5112 can all be infrared sensors of model LH1958.

[0098] In summary, the bearing press-fitting device provided in this embodiment has the following advantages:

[0099] When the bearing pressing device is in use, the bearing feeding component 2 can be used to arrange a number of bearings 7 placed randomly together in an orderly manner and then supply them to the material taking component 4. At the same time, the installation shaft feeding component 3 can be used to arrange a number of installation shafts 8 placed randomly together in an orderly manner and then supply them to the material taking component 4. Then, the material taking component 4 can be used to simultaneously take out the orderly arranged bearings 7 and the installation shafts 8 and supply them to the pressing device 5. Then, the pressing device 5 is used to press the installation shafts 8 supplied by the material taking component 4 into the inner ring of the supplied bearing 7, and the assembly work of the installation shafts 8 and the bearings 7 is automatically completed, which can greatly improve work efficiency and effectively reduce the work intensity of the staff.

[0100] During operation, a matching manipulator is installed on the unloading window 103, and the empty press-fitting jig 5113 can be placed on the upper part of the two conveyor belts 5104 by the manipulator. At the same time, the press-fitting jig 5113 containing the assembled installation shaft 8 and the bearing 7 can be removed from the upper part of the support plate 5201 by the manipulator and placed on the conveyor belt of the next process.

[0101] First, open the double-leaf door 104, pour the bearing 7 to be assembled into the inside of the annular enclosure 203, pour the installation shaft 8 to be assembled into the inside of the loading box 301, and then start the bearing press-fitting device to enter the automatic working mode through the touch screen 601 or the operation button 602;

[0102] The motor 1 212 drives the swinging disc 204 to rotate and automatically sort the bearings 7 randomly placed in the annular enclosure 203. During the rotation of the swinging disc 204, the bearings 7 can be driven to pass through the bearing feed port 213 in sequence into the discharge channel 205. As the number of bearings 7 in the discharge channel 205 increases, the rear bearings 7 push the front bearings 7 into the feeding channel 206 and reach the upper part of the conveyor belt body 207. The motor 211 drives the active synchronous pulley 214 to drive the driven synchronous pulley 209 to rotate through the synchronous belt 210. The driven synchronous pulley 209 drives the conveyor belt body 207 to move and transport the bearings 7 on the upper part of the conveyor belt body 207 to the material taking component 4.

[0103] When the two sensors 1 312 sense that there is no mounting shaft 8 in the corresponding position inside the long V-shaped swing material slot 308, the PLC controller controls the piston rod of the ejection cylinder 310 to extend according to the sensing signal of the sensor 1 312, and the ejection cylinder 310 pushes the mounting plate 309 to drive the ejection plate 1 302 and the ejection plate 2 304 to rise at the same time. When the ejection plate 1 302 rises, several mounting shafts 8 on the bottom surface of the loading box 301 are lifted up, so that several mounting shafts 8 fall into the top surface of the guide plate 1 303, and at the same time, when the ejection plate 2 304 rises, the mounting shafts 8 on the top surface of the ejection plate 304 are lifted up. The shaft 8 is lifted up and falls into the long V-shaped swing material slot 308. The installation shaft 8 falling into the long V-shaped swing material slot 308 is automatically vertical under the action of gravity, and then the linear electric slide 311 drives the push rod 306 to push the installation shaft 8 inside the long V-shaped swing material slot 308 to the side close to the sensor 1 312. When the piston rod of the ejection cylinder 310 contracts, the ejection plate 1 302 and the ejection plate 2 304 are simultaneously lowered, and the installation shaft 8 on the top surface of the guide plate 1 303 falls on the top surface of the ejection plate 2 304, thereby completing the purpose of automatic loading of the installation shaft 8;

[0104] The second linear electric slide 403 simultaneously drives the installation shaft material taking cylinder 406 and the bearing material taking cylinder 404 to move linearly toward the conveyor belt body 207 and the long V-shaped swing material slot 308, so that the bearing clamp 408 clamps the bearing 7 on the upper part of the conveyor belt body 207, and at the same time, the installation shaft clamp 409 clamps the installation shaft 8 in the long V-shaped swing material slot 308;

[0105] The driving motor 5105 drives the active conveyor belt roller 5103 to rotate, and the active conveyor belt roller 5103 cooperates with the driven conveyor belt roller 5108 to drive the two conveyor belts 5104 to rotate. The two conveyor belts 5104 drive the upper pressing fixture 5113 to move toward the second sensor 5107. When the upper pressing fixture 5113 of the two conveyor belts 5104 approaches the second sensor 5107, the PLC controller controls the piston rod of the lifting cylinder 5114 to extend according to the sensing signal of the second sensor 5107. The long lifting plate 5115 lifts the press-fitting fixture 5113 near the second sensor 5107. When the second sensor 5107 senses that the press-fitting fixture 5113 is approaching and the third sensor 5112 senses that there is a press-fitting fixture 5113 above it, the PLC controller drives the motor 5105 to stop working. After the lifted press-fitting fixture 5113 is transferred to the upper part of the support plate 5201 and the piston rod of the lifting cylinder 5114 is retracted, the PLC controller drives the motor 5105 to continue working.

[0106] When the press-fitting fixture 5113 is lifted, the PLC controller controls the linear electric slide 3 5301 to drive the moving seat 5302 to drive the pneumatic clamp 5307 to move to the top of the lifted press-fitting fixture 5113, and then controls the lifting cylinder 5303 to drive the pneumatic clamp 5307 to descend and clamp the lifted press-fitting fixture 5113, and then controls the linear electric slide 3 5301 to drive the moving seat 5302 to drive the pneumatic clamp 5307 to move to the top of the workstation 5203 closest to the lifting plate 5115, and then controls the lifting cylinder 5303 to drive the pneumatic clamp 5307 to descend and place the clamped press-fitting fixture 5113 inside the corresponding workstation 5203;

[0107] Then the PLC controller controls the linear electric slide 2 403 to simultaneously drive the installation shaft picking cylinder 406 and the bearing picking cylinder 404 to move linearly toward the conveyor body 207 and the long V-shaped swing material slot 308, so that the bearing picking cylinder 404 drives the bearing clamp 408 to descend to the picking notch 208 on the feeding channel 206 to clamp the bearing 7 on the upper part of the conveyor body 207, and at the same time, the installation shaft picking cylinder 406 drives the installation shaft clamp 409 to descend to the top of the long V-shaped swing material slot 308 to clamp the sorted installation shaft 8, and then controls the piston rod of the bearing picking cylinder 404 and The piston rod of the installation shaft picking cylinder 406 is retracted, and then the linear electric slide 2 403 is controlled to simultaneously drive the installation shaft picking cylinder 406 and the bearing picking cylinder 404 to move to the top of the corresponding workstation 5203, and then the PLC controller controls the bearing picking cylinder 404 to drive the bearing clamp 408 to descend and place the clamped bearing 7 in the positioning groove 51131 on the upper part of the press-fitting fixture 5113 in the workstation 5203, and then the piston rod of the bearing picking cylinder 404 is controlled to retract to raise the bearing clamp 408, and then the PLC controller controls the linear electric slide 3 5301 to drive the moving seat 5302 to drive The pneumatic clamp 5307 grabs the press-fitting fixture 5113 with the bearing 7 placed in the positioning groove 51131 and places it in the workstation 5203 below the mounting shaft clamp 409, and then the PLC controller controls the mounting shaft picking cylinder 406 to drive the mounting shaft clamp 409 to descend and place the mounting shaft 8 into the inner ring of the bearing 7 in the positioning groove 51131, and then controls the mounting shaft picking cylinder 406 to drive the mounting shaft clamp 409 to rise, and the PLC controller controls the linear electric slide 3 5301 to drive the moving seat 5302 to drive the pneumatic clamp 5307 to install the press-fitting fixture 5113 with the bearing 7 and the mounting shaft 8. Grab and place it in the workstation 5203 under the pressure head 5402, then the PLC controller controls the linear electric slide 3 5301 to drive the moving seat 5302 to drive the pneumatic clamp 5307 to move to a position that does not affect the operation of the pressure head 5402, then the PLC controller controls the press cylinder 5401 to drive the pressure head 5402 to press down and tighten the installation shaft 8 in the inner ring of the bearing 7, then the PLC controller controls the linear electric slide 3 5301 to drive the moving seat 5302 to drive the pneumatic clamp 5307 to move the pressed fixture 5113 toward the workstation 5203 at the position of the blanking window 103,

[0108] The robot places the empty press-fitting jig 5113 on the upper part of the two conveyor belts 5104. At the same time, the robot removes the press-fitting jig 5113 containing the assembled installation shaft 8 and bearing 7 from the upper part of the support plate 5201 and places it on the conveyor belt of the next process, thereby automatically completing the automated assembly of the bearing 7 and the installation shaft 8.
