[0086] The present invention provides a method for using a transmission roller bearing hydraulic installation device, comprising the following steps:

[0087] S1. Workpiece installation: conveying the conveying roller to the conveying structure 4 through an external conveying device, and then conveying the conveying roller to the first installation structure 21 through the conveying structure 4, and conveying the bearing to the second installation structure 22 through an external conveying device.

[0088] S2. Workpiece conveying: driving the rotating ring 12 to rotate and drive the multiple installation mechanisms 2 to rotate, and conveying the multiple installation mechanisms 2 to the bottom of the pressing mechanism 3 in sequence.

[0089] S3. Workpiece installation: The bearing on the second installation structure 22 is taken and fixed by the fixing structure 35 at the bottom of the press-fitting mechanism 3, and the bearing is press-fitted and fixed to the outer periphery of the conveying roller by the press-fitting mechanism 3.

[0090] S4. The workpiece is unloaded by driving the rotating ring 12 to rotate and drive the multiple installation mechanisms 2 to rotate, and the conveying roller with the bearing installed is taken out.

[0091] The working principle and use process of the present invention:

[0092] By starting the first stepper motor 14, the driving gear 15 can be driven to rotate. At the same time, the driving gear 15 can drive the rotating ring 12 to rotate around the fixed cylinder 11 through the driven gear ring 16. During this process, the active rotating ring 12 will drive the multiple mounting mechanisms 2 on its surface to rotate synchronously, so that the multiple mounting mechanisms 2 correspond to the external conveying equipment in turn. When the mounting mechanisms 2 correspond to the external conveying equipment, the bearings can be transported to the top of the second mounting structure 22 through the external conveying equipment and positioned between the multiple positioning rods 2213.

[0093] By starting the fourth stepper motor 46, the rotating member 47 can be driven to rotate, so that the top end opening of the conveying groove 414 inside the rotating member 47 is aligned with the feed groove 44 and the discharge groove 45 in sequence, and the bottom opening of the conveying groove 414 is aligned with the through groove 43 in sequence and stops;

[0094] In this process, the transmission rollers can be placed in the multiple conveying grooves 414 in sequence through the feed groove 44 by the external conveying equipment, and when the top of the conveying groove 414 is aligned with the discharge groove 45 and the bottom is aligned with the through groove 43, the fifth stepping motor 49 can be started to drive the threaded rod to rotate forward, and drive the lifting member 411 threadedly connected thereto to drive the ejector rod 413 to eject the transmission rollers in the conveying groove 414 in the conveying groove 414, and make the top wall of the transmission roller pass through the discharge groove 45, the first through hole 211 on the surface of the rotating ring 12 and the second mounting hole on the surface of the first mounting plate 212 in sequence to enter the middle of the first mounting structure;

[0095] At this time, the second stepper motor 2110 can be started to drive the driving gear 2111 to rotate, and the driving gear 2111 will drive the two bidirectional threaded rods 218 to rotate through the two linkage gears 219 respectively, and the two bidirectional threaded rods 218 rotate in opposite directions. However, because the thread grooves on the surfaces of the two bidirectional threaded rods 218 rotate in opposite directions, the two clamping blocks 216 can be driven to move between the two bidirectional threaded rods 218 along the axial direction of the two bidirectional threaded rods 218 through the rotation of the two bidirectional threaded rods 218. By controlling the rotation direction of the output shaft of the second stepper motor 2110, the two clamping blocks 216 can be driven to move toward or away from each other, so that the conveying roller arranged between the two clamping grooves 217 can be clamped or loosened through the clamping grooves 217 on the surfaces of the two clamping blocks 216. At this time, the two clamping blocks 216 are controlled to approach and fix the transmission roller inserted between the two clamping blocks 216, and then the fifth stepper motor 49 is started to drive the threaded rods to rotate in the opposite direction, so that the push rod 413 is reset.

[0096] Through the above steps, the transmission roller can be transported into the first mounting structure 21 in the mounting mechanism 2 and fixed, and the bearing can be placed and positioned on the top of the second mounting structure 22. After that, the rotating ring 12 can drive the mounting mechanism 2 equipped with the transmission roller and the bearing to move to the bottom of the pressing mechanism 3. At this time, the hydraulic push rod 33 can be started to drive the movable plate 34 to move downward. When the movable plate 34 moves downward, the mounting column 352 can be driven to move downward synchronously until the first mounting groove 353 at the bottom of the mounting column 352 is sleeved on the outer periphery of the bearing between the multiple positioning rods 2213. At this time, the third stepping motor 3510 can be started to drive the rotating disk 3511 and the multiple guide grooves 3512 to rotate forwardly. At the same time, the multiple guide grooves 3512 will squeeze the multiple guide shafts 3514 respectively, and drive the multiple extension rods 3513 to move synchronously through the multiple guide shafts 3514. At the same time, the ends of the multiple extension rods 3513 will drive the multiple clamping blocks 216 to move synchronously toward the bearing and clamp and fix the bearing.

[0097] After that, the movable plate 34 continues to move downward and can drive the bearing to move downward synchronously through the mounting column 352. At the same time, the retaining ring 357 on the outer periphery of the mounting column 352 will squeeze the second movable ring 225. By squeezing the second movable ring 225 downward and moving the second movable ring 225 downward, the multiple second mounting frames 2211 connected thereto can be driven to move downward at the same time. At this time, the driven gears 2215 at both ends of the rotating rod 2212 connected to the second mounting frame 2211 move downward relative to the two active racks 2216 connected to the fixed frame 226. At the same time, the two active racks 2216 will drive the two driven gears 2215 and the rotating rod 2212 to rotate. At the same time, the rotating rod 2212 will drive the positioning rod 2213 fixedly connected thereto to deflect downward to a vertical state with the rotating rod 2212 as the axis.

[0098] When the second movable ring 225 moves downward, the connecting member 227 will be driven to move downward in the fixed frame 226 through the connecting rod 228. At this time, the connecting member 227 will squeeze and compress the second return spring 229 until the connecting member 227 is against the limit members 2210 fixedly connected to the inner walls of the fixed frame 226. At this time, when the second movable ring 225 is continuously squeezed downward and continues to be driven to move downward, the second movable ring 225 will squeeze the limit members 2210 through the connecting rod 228 and the connecting member 227 and drive the first movable ring 221 to move downward through the fixed frame 226. At the same time, the first movable ring 221 will squeeze and compress the first return spring 224. At this time, because the driven gear 2215 and the active rack 2216 no longer move relative to each other, the positioning rod 2213 in the vertical state will no longer continue to deflect.

[0099] In this process, the bearing is squeezed by the mounting column 352 and the bearing sleeve is fixed on the outer periphery of the transmission roller. At the same time, the top end of the transmission roller is inserted into the second mounting groove 354, thereby completing the installation and fixation between the bearing and the transmission roller.

[0100] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
