Description

Technical Field

[0001] This utility model relates to the field of speed reducer processing technology, and in particular to a coating press-in machine. Background Technology

[0002] A gear reducer is a power transmission mechanism that reduces speed and increases torque through combinations of gears with different numbers of teeth. It is widely used in industrial machinery, automotive transmissions, automation equipment, and many other fields. It typically consists of a housing, gear shafts, bearings, and other components. The gears are mostly made of alloy steel and undergo heat treatment processes such as quenching to improve wear resistance and fatigue strength. Based on the transmission type, it can be divided into cylindrical gear reducers, bevel gear reducers, planetary gear reducers, etc. Different structures are suitable for different working scenarios, such as right-angle shaft drives or compact space arrangements. Its core function is to reduce the speed of high-speed power sources such as motors to meet the low-speed, high-torque requirements of mechanical equipment, while improving the stability and accuracy of power transmission. It is an indispensable key component in mechanical transmission systems.

[0003] During the assembly of a gear reducer, the bearing needs to be pressed into the reducer housing and lubricating oil needs to be applied to the inner wall of the housing to reduce the frictional loss of the reducer spindle and internal parts. The existing reducer assembly is usually done manually. Manually pressing the bearing into the reducer is not only time-consuming and laborious, but also prone to problems such as incomplete pressing, which affects the accuracy of the reducer. Manually applying lubricating oil is often difficult to apply evenly. Utility Model Content

[0020] refer to Figures 1 to 5 This invention describes a coating press-fit machine according to an embodiment of the present invention.

[0021] like Figures 1 to 5 As shown, the coating press-in machine according to an embodiment of the present invention includes: a frame 100; a pressing mechanism 200, which is disposed at the front end of the frame 100 and includes a fixed seat 210 and a lower pressing member. The fixed seat 210 is disposed on the frame 100 and is used to fix the reducer housing. The lower pressing member is movably disposed above the fixed seat 210 and is used to grip the bearing and press it into the reducer housing by moving downward; and a coating mechanism 300, which is disposed at the rear end of the frame 100 and includes a rotating seat 310 and an oiling member 320. 10 is mounted on the frame 100. The rotating seat 310 is used to clamp the reducer housing and drive the reducer housing to rotate. The oiling component 320 is movably mounted above the rotating seat 310. While the rotating seat 310 drives the reducer housing to rotate, the oiling component 320 moves upward along the inner wall of the reducer housing and applies lubricating oil in a spiral pattern on the inner wall of the reducer housing. The movable gripper 400 is mounted on the frame 100 and is used to transport the reducer housing with the bearing pressed into it on the fixed seat 210 to the rotating seat 310.

[0022] like Figures 1 to 5As shown, the reducer housing is placed on the fixed seat 210 at the front end of the frame 100, and the bearing to be pressed in is placed in the reducer housing. The cylinder 211 drives the lower pressing head 212 to move downward, and the lower pressing head 212 presses the bearing into the reducer housing to complete the bearing pressing process. The rotating part 420 of the moving jaw 400 rotates, aligning the jaw 430 with the reducer housing with the bearing assembled. The first lifting part 410 drives the jaw 430 to descend, and at the same time, the left and right moving part 431 drives the two clamping plates 43 2. The two clamping plates 432 are positioned on the left and right sides of the reducer housing, respectively. At this time, the left and right moving component 431 drives the two clamping plates 432 to move closer together to clamp the reducer housing. After clamping, the first lifting component 410 drives the gripper 430 to rise, removing the reducer housing from the fixed seat 210. The rotating component 420 drives the gripper 430 to rotate 180 degrees, aligning the clamped reducer housing with the rotating seat 310. The gripper 430 then places the reducer housing into the rotating seat 310. Through the movement of the second lifting component 324 and the telescopic component 322, the nozzle 323 is pressed against the inner wall of the reducer housing. The rotating seat 310 drives the reducer to rotate, while the second lifting component 324 drives the nozzle 323 to slowly move upward, causing the lubricating oil sprayed from the nozzle 323 to be evenly coated on the inner wall of the reducer housing in a spiral pattern. Therefore, this coating press-in machine can replace manual labor in completing the bearing press-in process and lubricant coating process in the assembly of reducers, and the bearing assembly is accurate and in place, and the lubricant coating is efficient and uniform.

[0023] In traditional processes, bearing pressing and lubricant coating often rely on manual operation or separate equipment, which is not only time-consuming and labor-intensive but also prone to quality problems such as incomplete bearing pressing and uneven lubricant coating. This coating and pressing machine, however, utilizes the pressing mechanism 200 at the front of the frame 100, with the fixed base 210 firmly supporting the reducer housing. The lower pressing component precisely grips the bearing and presses it into the housing, ensuring the accuracy of bearing assembly. The coating mechanism 300 at the rear of the frame 100 rotates the housing via a rotating base 310, while the lubricating component 320 spirals upwards along the inner wall to apply lubricant, achieving uniform lubricant distribution. The moving gripper 400 precisely and efficiently transfers the assembled bearing housing to the coating station, avoiding errors and damage that may occur with manual handling. This highly integrated design not only significantly shortens the assembly cycle and reduces labor costs but also effectively improves the overall quality and performance of the reducer assembly.

[0024] like Figure 3 and Figure 4As shown, the movable gripper 400 includes a first lifting member 410, a rotating member 420, and a gripper 430. The first lifting member 410 is mounted on the frame 100, the rotating member 420 is located at the lower end of the first lifting member 410, and the gripper 430 is mounted on the rotating member 420. The rotating member 420 drives the gripper 430 to move above the reducer housing to be gripped, and the first lifting member 410 drives the gripper 430 to move up and down to grasp the reducer housing. By setting the first lifting member 410, the rotating member 420, and the gripper 430, this design gives the movable gripper 400 more precise motion control capabilities in the vertical and horizontal directions. In actual operation, the rotating member 420 can accurately move the gripper 430 above the reducer housing to be gripped, ensuring accurate alignment between the gripper 430 and the target housing. Subsequently, the first lifting component 410 drives the gripper 430 to descend smoothly and stably grip the reducer housing. This process effectively avoids problems such as housing damage or bearing loosening that may be caused by inaccurate positioning of the gripper 430 or unstable gripping action.

[0025] like Figure 3 and Figure 4 As shown, two grippers 430 are provided, symmetrically arranged on the rotating member 420 along the front-to-back direction. The distance between the two grippers 430 is equal to the distance between the fixed seat 210 and the rotating seat 310. Therefore, the rotating member 420 only needs to rotate 180 degrees to move the grippers 430 from above the fixed seat 210 to above the rotating seat 310, and vice versa. This enables rapid movement of the reducer housing between the pressing and coating stations. The two symmetrically arranged grippers 430 can apply force to the reducer housing synchronously and evenly, ensuring the housing remains stable during gripping and transfer, avoiding tilting or shaking caused by uneven force, thus effectively preventing bearing displacement or loosening within the housing and ensuring the assembly quality of the bearing pressing process. In addition, the precise matching between the spacing of the gripper 430 and the spacing between the fixed seat 210 and the rotating seat 310 makes the moving gripper 400 more accurate and smooth when gripping and placing the reducer housing, reducing the adjustment time and idle stroke of the equipment and significantly improving assembly efficiency.

[0026] like Figure 4As shown, the gripper 430 includes a left-right moving member 431 and two clamping plates 432. The left-right moving member 431 is mounted on the rotating member 420, and the two clamping plates 432 are both mounted on the left-right moving member 431. The left-right moving member 431 drives the two clamping plates 432 to move closer together to grip the reducer housing. By setting two clamping plates 432 on the left-right moving member 431 and using the left-right moving member 431 to drive the clamping plates 432 closer or further apart, the gripper 430 structure can flexibly adjust the clamping force and applicable range. In practical applications, when the gripper 430 moves above the reducer housing, the left-right moving member 431 first drives the clamping plates 432 to move further apart, so that the clamping plates 432 are smoothly positioned on both sides of the housing, and then drives the clamping plates 432 to move closer together, thereby achieving a stable grip on the housing. This design not only effectively avoids housing deformation or damage caused by excessive clamping force, but also adapts to reducer housings of different sizes and shapes, greatly enhancing the versatility and flexibility of the equipment.

[0027] like Figure 1 As shown, the pressing component includes a cylinder 211, which is positioned downwards. The output shaft of the cylinder 211 is connected to a pressing head 212. The pressing component also includes a guide rod 213, the lower end of which is connected to the pressing head 212. The guide rod 213 passes through the frame 100 in the vertical direction. The cylinder 211 can stably output downward pressure, driving the pressing head 212 to press the bearing evenly and smoothly into the reducer housing. Compared with traditional manual or mechanical pressing methods, the pressing component driven by the cylinder 211 can not only ensure that the applied pressure is constant and controllable, effectively avoiding problems such as incomplete bearing pressing due to insufficient pressure or housing deformation caused by excessive pressure, but also significantly improve the pressing speed and work efficiency. During the bearing pressing process, the guide rod 213 can effectively prevent the pressing head 212 from shifting or shaking under force, ensuring that the pressing head 212 always moves smoothly and accurately in the vertical direction, thereby ensuring the coaxiality and assembly accuracy between the bearing and the reducer housing. Furthermore, the guide rod 213 enhances the overall rigidity of the pressing component, enabling it to withstand greater pressing forces and adapt to the pressing requirements of bearings of different specifications and sizes. Through its synergistic effect with the cylinder 211, the guide rod 213 further improves the working stability and reliability of the pressing component.

[0028] like Figure 2 and Figure 5As shown, the oiling component 320 includes an oil gun and a second lifting component 324. The second lifting component 324 is mounted on the frame 100, and the oil gun is tilted on the second lifting component 324. The oil gun includes a telescopic component 322 and a nozzle 323. The telescopic component 322 is tilted on the second lifting component 324, and the nozzle 323 is mounted on the telescopic component 322. The telescopic component 322 drives the nozzle 323 to move towards the reducer housing, so that the nozzle 323 abuts against the inner wall of the reducer housing. The telescopic component 322 drives the nozzle 323 to move towards the inner wall of the housing, so that the nozzle 323 fits tightly against the inner wall, ensuring that the lubricating oil can be accurately applied to the predetermined position. This direct contact coating method can not only effectively avoid the problem of uneven coating caused by splashing or uneven atomization of lubricating oil during the spraying process, but also flexibly adjust according to the shape and size of the inner wall of the housing, achieving full coverage of complex inner wall structures. Through the coordinated cooperation with the rotating seat 310 and the second lifting component 324, this design achieves a spiral uniform coating of lubricating oil on the inner wall of the housing.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
