In the large-scale production of gears, pressing gears onto shafts or bearings is a critical process. The quality of this assembly directly affects the smoothness, noise, and service life of gear transmission. Therefore, a highly reliable gear press is needed to complete this critical step.

[0003] However, when using existing gear presses, it is not easy to center the gear and shaft during the press-fitting process, making it difficult to ensure that the two are coaxial. This affects the stability of the press-fitting process, causing the shaft to shift during press-fitting and resulting in damage to the shaft and gear. Utility Model Content

[0016] This utility model has the following beneficial effects:

[0017] 1. By setting a centering downward pressing part, when the positioning pin and its gear and shaft move below the centering downward pressing part, the hydraulic cylinder under the support rod is opened. The hydraulic cylinder stretches and drives the transmission rod to descend. The limiting block descends with this process until its first bucket-shaped part contacts and squeezes the gear on the positioning pin, thus centering the gear. At the same time, the shaft on the gear contacts and is squeezed by the second bucket-shaped part of the limiting block, thus centering the shaft as well. At this point, the transmission rod continues to descend, while the limiting block is already stopped because the gear has reached the connection point of the two bucket-shaped areas. The transmission rod drives the circular slider and the hollow extrusion block to descend, thus squeezing the hollow extrusion block. The shaft on the pressing gear is pressed onto the gear. During this process, the transmission rod slides down the protective shell, and the spring is compressed and contracted by the circular slider. After the gear and shaft are pressed together, the hydraulic cylinder is controlled to contract, the central pressing part separates from the gear, and all parts are reset. The motor is turned on again to transport the processed gear to the gear assembly part on the right. The gear is then transported out of the device through this gear assembly part, completing the processing of one gear. During pressing, the downward pressure of the pressing can automatically center the gear and shaft to ensure that their axes are coaxial, thereby achieving smooth pressing and avoiding displacement or damage caused by misalignment during pressing.

[0018] 2. By setting up a gear assembly section, when assembling gears and shafts, the process of one of them is analyzed. First, open the gear assembly section located on the rear side. The electric telescopic rod one retracts or extends, causing the hollow rectangular rod to move forward or backward, thereby driving the clamping component and power component at the bottom of the hollow rectangular rod to move. Adjust in this way until the gear on the feeding guide rail located on the rear side is at the center of the four jaws. Control the electric telescopic rod two to extend until the four jaws descend to the same height as the gear. Open the electric telescopic rod three, and the bracket two retracts, causing the connecting block to move closer to the bracket two. The connecting block drives the second bracket to rotate via the corresponding L-shaped hinge rod. The second bracket drives the corresponding grippers to approach the second bracket via the other three second brackets. As a result, several grippers approach each other until they clamp the gear. The electric telescopic rod three is closed, and the transfer component is controlled to drive the clamping component to bring the gear to the positioning pin and insert it. Then, the electric telescopic rod three is controlled to extend, so that the four grippers release the gear. This completes the gripping, transfer and positioning of parts. At the same time, it cooperates with the rotation of the turntable to make the pressing process continuous, thereby significantly improving production efficiency and realizing the automated and batch assembly of gears.

At the same time, it cooperates with the rotation of the turntable to make the pressing process continuous, thereby significantly improving production efficiency and realizing the automated and batch assembly of gears.

[0040] Using a press that automatically assembles gears, as described above:

[0041] When in use, first assemble the gears and shafts. The shaft used is a hollow rotating shaft. The size of the hollow extrusion block 222 is adapted to the shaft. This device can process four gears at the same time. Analyze the process of one of them. First open the gear assembly part 3 located on the rear side. The electric telescopic rod 313 retracts or extends, which drives the hollow rectangular rod 312 to move forward or backward, thereby driving the clamping component 32 and the power component 33 at the bottom of the hollow rectangular rod 312 to move. Adjust in this way until the gear on the feeding guide rail 119 located on the rear side is located at the center of the four grippers 324.

[0042] Extend the electric telescopic rod 314 until the four grippers 324 descend to the same height as the gear. Open the electric telescopic rod 332. The second bracket 322 retracts, causing the connecting block 333 to move closer to the second bracket 322. The connecting block 333, through the corresponding L-shaped hinge rod 323, causes the second bracket 322 to rotate. The second bracket 322, through the other three second brackets 322, causes the corresponding grippers 324 to move closer to the second bracket 322. Thus, several grippers 324 move closer together until they clamp the gear. Close the electric telescopic rod. The telescopic rod 332 controls the transfer assembly 31, which drives the clamping assembly 32 to bring the gear to the positioning pin 114 and insert it. Then, the electric telescopic rod 332 is extended, so that the four grippers 324 release the gear. Then, the motor 115 is turned on. The motor 115 drives the gear 118 to rotate through the rotating shaft 116. The gear 118 drives the hollow turntable 113 to rotate on the worktable 111 through the gear ring 117, thereby bringing the rear positioning pin 114 and the gear on it to the clamping assembly 32 on the left.

[0043] Then, the motor 115 is stopped. The shaft is inserted into the positioning pin 114 through the clamping assembly 32, its transfer assembly 31, and the power assembly 33. The motor 115 is then turned on again, causing it to move the corresponding positioning pin 114 and its gear and shaft to the centering pressing part 2. At this time, the hydraulic cylinder 212 under the support rod 211 is opened. The hydraulic cylinder 212 stretches and drives the transmission rod 213 to descend. The limiting block 223 descends with this process until its first bucket-shaped part contacts and squeezes the gear on the positioning pin 114, centering the gear. At the same time, the shaft on the gear contacts and is squeezed by the second bucket-shaped part of the limiting block 223, thus centering the shaft as well. At this time, the transmission rod 213 continues to descend. The gear descends, and the limiting block 223 is stopped by the connection between the two bucket-shaped areas. The transmission rod 213 drives the circular slider 221 and the hollow extrusion block 222 to descend, so that the hollow extrusion block 222 extrudes the shaft on the gear and presses it onto the gear. During this process, the transmission rod 213 slides down the protective shell 214, and the spring 224 is compressed and contracted by the circular slider 221. After the gear and shaft are pressed together, the control hydraulic cylinder 212 contracts, the central pressing part 2 separates from the gear and all parts are reset, and the motor 115 is turned on again to transport the processed gear to the gear assembly part 3 located on the right. The gear is then transported out of the device through this gear assembly part 3, completing the processing of one gear.
