Description

Technical Field

[0001] The utility model relates to the technical field of gearbox production, and specifically relates to a servo press-fitting device for gearbox bearing shaft rods. Background Art

[0002] In the production process of a gearbox, the press-fitting of the housing and the bearing, as well as the press-fitting of the shaft rod inside the bearing, are two crucial steps. These two steps not only directly relate to the assembly accuracy and overall performance of the gearbox, but also have a significant impact on the efficiency and cost of the entire production line. However, under the existing production technology conditions, these two press-fitting steps usually need to be carried out on two independent press-fitting devices respectively, and this current situation brings various challenges and inconveniences.

[0003] Firstly, from the perspective of the production process, after the press-fitting of the bearing on the housing is completed, it is necessary to transfer the gearbox from one device to another manually or mechanically for the press-fitting of the shaft rod. This transfer process not only increases the production time, but also may introduce additional operation errors, such as inaccurate positioning, component bumping, etc., thus affecting the assembly quality and consistency of the product.

[0004] Secondly, from the perspective of cost control, the configuration and maintenance costs of the two devices are relatively high. In addition, due to the need to transfer the gearbox, it may also increase the space occupation on the production line and the material handling cost. In today's increasingly competitive market, these additional costs will undoubtedly have an adverse impact on the profitability and market competitiveness of the enterprise.

[0005] Furthermore, from the perspective of production efficiency, due to the dispersion of the press-fitting steps and the existence of the transfer process, the cycle time of the entire production line is lengthened, reducing the overall production efficiency. This is undoubtedly an urgent problem to be solved for enterprises that pursue rapid response to market changes and efficient production. Content of the Utility Model

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0039] Please refer to Figure 1 、 2, 3, the present utility model provides a technical solution: a servo press-fitting device for a gearbox bearing shaft rod, which is composed of a device frame 1, a conveyor belt 2, a first driving module 3, a second driving module 4, a first press-fitting driven module 5, a second press-fitting driven module 6, a servo press-fitting active module 7, a safety light curtain 8 and a control switch 9. Among them, the conveyor belt 2 is arranged at the bottom of the device frame 1, and the conveyor belt 2 can convey the pre-assembled (that is, the state where it has been placed at the assembly part but not yet press-fitted) gearbox 10, shaft rod 11 and bearing 12. The first driving module 3 is installed in the middle of the device frame 1, the second driving module 4 is installed on the driving end of the first driving module 3, the first press-fitting driven module 5 is installed on the driving end of the second driving module 4, and the second press-fitting driven module 6 is installed on the driving end of the first driving module 3. That is to say, the first driving module 3 can simultaneously drive the second driving module 4, the first press-fitting driven module 5 and the second press-fitting driven module 6 to move in the horizontal direction, while the second driving module 4 can only drive the first press-fitting driven module 5 to move in the vertical direction. The servo press-fitting active module 7 is installed on the top of the device frame 1. During specific operation, this device can successively perform the process of press-fitting the bearing 12 into the housing of the gearbox 10 and the process of press-fitting the shaft rod 12 into the inside of the bearing 12. For which step, the first press-fitting driven module 5 and the second press-fitting driven module 6 can be called. No matter which one is called, it will be directly below the servo press-fitting active module 7. The safety light curtain 8 is installed on both sides of the front of the device frame 1, which plays a role in ensuring the personal safety of the staff when the device is working. The control switch 9 is installed on the front of the conveyor belt 2, and the staff controls the entire device through the control switch 9;

[0040] Please refer to Figure 4 , 5、6, 7, the first press-fitting driven module 5 includes an outer frame 51 installed on the driving end of the second driving module 4. An inner frame 52 is connected inside the outer frame 51 (the outer frame 51 and the inner frame 52 are an integral whole). A number of connecting rods 53 are slidably connected inside the outer frame 51 and the inner frame 52 through linear bearings. The tops of the number of connecting rods 53 extend above the outer frame 51 and are commonly connected to a pressure-receiving plate 54 (the pressure applied by the servo press-fitting active module 7 will act on the pressure-receiving plate 54 immediately). The bottoms of the number of connecting rods 53 extend below the outer frame 51 and are commonly connected to a press-fitting plate 55 (the press-fitting plate 55 will press down the bearing 12 into the bearing installation position reserved on the housing of the transmission 10). One-way reset cylinders 59 are installed on both sides of the outer frame 51. The telescopic ends of the one-way reset cylinders 59 are connected to the pressure-receiving plate 54 (the function of the two one-way reset cylinders 59 is that after the press-fitting work of the bearing 12 is completed, the one-way reset cylinders 59 synchronously push the whole of the pressure-receiving plate 54, the number of connecting rods 53, and the press-fitting plate 55 upward to the initial position, that is, reset). In addition, during the process of pressing the bearing 12 into the transmission 10, the shaft rod 11 can also be clamped and fixed. Specifically, a clamping driving cylinder 56 is installed at the top of the inner frame 52. A lifting frame 57 is slidably connected to the bottoms of the outer frame 51 and the inner frame 52. The bottom end of the lifting frame 57 extends below the outer frame 51, and a shaft hole 571 is reserved. The top end of the lifting frame 57 is connected to the telescopic end of the clamping driving cylinder 56 (the clamping driving cylinder 56 can drive the lifting frame 57 to move vertically). A shaft rod chuck 58 is installed at the bottom end of the outer frame 51. The shaft rod chuck 58 includes an outer disk body 581 installed at the bottom end of the outer frame 51. The middle of the outer disk body 581 is hollowed out. A number of inner clamping plates 582 are movably arranged in the hollowed-out area. The number of inner clamping plates 582 can all move along the radial direction of the outer disk body 581. The outer disk body 581 and the inner clamping plates 582 are connected by a number of springs 583. The bottom end of each inner clamping plate 582 extends below the outer disk body 581 and is set as a conical surface 584. The conical surface 584 is the core structure for clamping. When the lifting frame 57 moves upward, the shaft hole 571 synchronously applies an inward squeezing force to the number of inner clamping plates 582 through the conical surface 584, prompting the number of inner clamping plates 582 to move synchronously towards the axis, thereby clamping and fixing the shaft rod 11. When it is necessary to release the shaft rod 11, the reverse operation is performed. Under the action of the spring 583, the number of inner clamping plates 582 is reset, and the shaft rod 11 can be released.

[0041] Please refer to Figure 8 、 9, 10. The second press-fitting driven module 6 includes a driven frame 61 installed on the driving end of the first driving module 3. A number of press-fitting rods 62 are slidably connected inside the driven frame 61. A press-fitting head 63 is installed at the bottom end of each press-fitting rod 62. A number of second reset cylinders 64 are also installed inside the driven frame 61. The telescopic end of each second reset cylinder 64 is connected to the corresponding press-fitting rod 62 (since multiple shaft rods 11 need to be press-fitted on the transmission 10, multiple press-fitting rods 62, press-fitting heads 63 and second reset cylinders 64 are provided in this module. Among them, the function of the second reset cylinder 64 is the same as that of the above-mentioned first reset cylinder 59, which is to make the press-fitting rod 62 move up and reset after the press-fitting rod 62 moves down to complete the press-fitting). The servo press-fitting active module 7 includes an X-axis driving module 71 installed on the top of the equipment frame 1. The driving end at the bottom of the X-axis driving module 71 is installed with a Y-axis driving module 72. The driving end of the Y-axis driving module 72 is installed with a servo cylinder 73. As mentioned above, since multiple shaft rods 11 need to be press-fitted on the transmission 10, multiple press-fitting rods 62, press-fitting heads 63 and second reset cylinders 64 are provided in this module. The X-axis driving module 71 and the Y-axis driving module 72 are designed to adjust the position of the servo cylinder 73. That is to say, when a corresponding shaft rod 11 needs to be press-fitted, the position of the servo cylinder 73 is adjusted to directly above the press-fitting rod 62 corresponding to the shaft rod 11.

[0042] It should be noted that the first driving module 3, the X-axis driving module 71, and the Y-axis driving module 72 are all structures driven by a servo motor to drive a lead screw. The second driving module 4 is a structure driven by an oil cylinder as a driving source and transmitted through a guide rail and a connecting member. The specific structures and principles of the above components are all publicly known technologies and will not be elaborated here.
