[0002] In the field of mechanical manufacturing, the press-fitting of the main reducing gear is a key process, and its press-fitting accuracy and efficiency directly affect the overall performance and service life of the equipment.

[0003] Currently, sleeve-type auxiliary pressing machinery is typically used to perform the pressing operation of main reducer gears. However, this type of machinery has many shortcomings in practical applications. First, the structural design of these machines is relatively complex, containing a large number of parts. This complexity not only significantly increases the manufacturing cost of the equipment but also makes daily maintenance and repair work more cumbersome and complicated. Once a component malfunctions or is damaged, troubleshooting and replacing the part becomes quite difficult and time-consuming. This situation not only delays the production schedule but also has a serious negative impact on overall production efficiency. Summary of the Invention

[0004] The main purpose of this utility model is to provide a main reducing gear pressing mechanism, which aims to provide a simple pressing mechanism to achieve effective pressing of the main reducing gear.

[0005] To achieve the above objectives, the present invention proposes a main tooth reduction pressing mechanism, which includes a connecting plate, a positioning component, and a pressing component; the top of the connecting plate is used to connect to a press, and the bottom of the connecting plate is fixedly connected to a plurality of positioning components and pressing components, with the bottom of the connecting plate facing the workpiece to be pressed.

[0006] The positioning component includes a positioning cylinder and a positioning gripper. The positioning cylinder is fixed to the connecting plate and can extend and retract radially from the connecting plate. The movable end of the positioning cylinder is connected to the positioning gripper. The positioning cylinder is used to drive the positioning gripper to abut against or move away from the workpiece.

[0007] The pressing component is vertically mounted on the connecting plate, and the bottom surface of the pressing component is higher than the bottom surface of the positioning gripper.

[0008] In some embodiments of this utility model, the positioning gripper includes a vertically arranged fixed base, a connecting member, and a gripper head. The fixed base is connected to the movable end of the positioning cylinder, and the gripper head is connected to the fixed base through the connecting member.

[0009] In some embodiments of this utility model, the connecting member includes a screw and an elastic connecting rod arranged at intervals. The two ends of the screw are respectively threaded to the fixed seat and the claw head, and the elastic connecting rod is elastically engaged with the fixed seat and the claw head.

[0010] In some embodiments of this utility model, a distance sensor is provided on the bottom of the connecting plate facing the workpiece.

[0011] In some embodiments of this utility model, the cross-sectional profile of the press-fitting component along the horizontal direction is fan-shaped.

[0012] In some embodiments of this utility model, the outer side of the claw head is an arc surface.

[0013] In some embodiments of this utility model, the number of pressing components and positioning components are both three, and the pressing components and positioning components are evenly distributed around the central axis of the connecting plate at 120 degrees to each other.

[0014] In some embodiments of this utility model, the pressing component and the positioning component are arranged alternately at intervals.

[0015] In some embodiments of this utility model, the connecting plate is provided with fastening holes for fixed connection with the press and positioning grooves for fitting.

[0016] In some embodiments of this utility model, the pressing component and the positioning component are distributed at 30-degree intervals around the central axis of the connecting plate.

[0017] This utility model's technical solution integrates the connecting plate, positioning component, and pressing component into a single design. Compared to traditional complex sleeve-type structures, this reduces the number of nested components, simplifies the overall structure, and lowers equipment manufacturing costs and maintenance difficulty. The positioning cylinder can extend and retract radially, driving the positioning gripper to directly act on the pressing position (inner ring) of the main reducing tooth for positioning, avoiding the problem of positioning difficulties due to other inaccurate parts of the main reducing tooth. At the same time, the bottom surface of the pressing component is higher than the positioning gripper, ensuring that the workpiece is accurately positioned by the positioning gripper first during the pressing process, and then pressure is applied by the pressing component, avoiding pressing offset caused by inaccurate positioning and ensuring pressing accuracy.

[0027] See appendix Figure 1-2This utility model proposes a main tooth reduction pressing mechanism, including a connecting plate 100, a positioning component 200 and a pressing component 300; the top of the connecting plate 100 is used to connect to the press, and a number of positioning components 200 and pressing components 300 are fixedly connected to the bottom of the connecting plate 100, with the bottom of the connecting plate 100 facing the workpiece 400 to be pressed.

[0028] The positioning component 200 includes a positioning cylinder 210 and a positioning gripper 220. The positioning cylinder 210 is fixed to the connecting plate 100 and can move radially and retract from the connecting plate 100. The movable end of the positioning cylinder 210 is connected to the positioning gripper 220. The positioning cylinder 210 is used to drive the positioning gripper 220 to abut against or move away from the workpiece 400.

[0029] The pressing component 300 is vertically mounted on the connecting plate 100, and the bottom surface of the pressing component 300 is higher than the bottom surface of the positioning gripper 220.

[0030] Based on the aforementioned technical features, by integrating the connecting plate 100, positioning component 200, and pressing component 300, compared to the complex structure of traditional sleeve-type components, multi-layer nested components are reduced, simplifying the overall structure and lowering equipment manufacturing costs and maintenance difficulty. The positioning cylinder 210 can extend and retract radially, driving the positioning gripper 220 to directly act on the pressing position (inner ring) of the main reducing gear for positioning, avoiding the problem of difficult positioning due to other inaccurate parts of the main reducing gear; at the same time, the bottom surface of the pressing component 300 is higher than that of the positioning gripper 220, ensuring that the positioning gripper 220 accurately positions the workpiece 400 first during the pressing process, and then the pressing component 300 applies pressure, avoiding pressing offset caused by inaccurate positioning and ensuring pressing accuracy.

[0031] The positioning gripper 220 includes a vertically arranged fixed base 221, a connecting member, and a gripper head 222. The fixed base 221 is connected to the movable end of the positioning cylinder 210, and the gripper head 222 is connected to the fixed base 221 via the connecting member. The positioning gripper 220 adopts a split structure for the fixed base 221, the connecting member, and the gripper head 222, making each component functionally independent. The fixed base 221 is connected to the positioning cylinder 210 to stably transmit driving force. The gripper head 222 is connected to the fixed base 221 via the connecting member. When the gripper head 222 is worn or needs to be adapted to different models of main reduction gears, it can be disassembled and replaced separately without replacing the entire positioning gripper 220, reducing maintenance costs and improving maintenance efficiency.

[0032] Furthermore, the connecting components include spaced-apart screws 223 and elastic connecting rods 224. The two ends of the screws 223 are threadedly connected to the fixed seat 221 and the claw head 222, respectively. The elastic connecting rods 224 are elastically engaged with the fixed seat 221 and the claw head 222. The vertically positioned screws 223 and elastic connecting rods 224 work together. The elastic connecting rods 224 provide the positioning claws 220 with axial elastic deformation capability, buffering impact force when contacting the workpiece 400 and absorbing vibration during the pressing process, ensuring a tight fit between the claw head 222 and the inner ring of the workpiece 400. The screws 223 serve as rigid supports, limiting the maximum float through the threaded connection and allowing for fine-tuning of the claw head 222 height to accommodate different specifications of main reducing teeth. The combination of these two components achieves a balance between flexible positioning and rigid pressing, avoiding damage to the workpiece 400 from rigid collisions and preventing gripping instability caused by purely elastic connections, effectively improving the stability and accuracy of the pressing process.

[0033] Specifically, a distance sensor 500 is provided on the bottom of the connecting plate 100 facing the workpiece 400. The distance sensor 500 at the bottom of the connecting plate 100 monitors the distance between the pressing mechanism and the workpiece 400 in real time and feeds the data back to the control system. The control system precisely controls the pressing stroke and speed of the press according to preset parameters. When approaching the workpiece 400, the pressing speed is automatically reduced to avoid impact on the workpiece 400 due to excessive speed. When the set distance is reached, the pressing action is triggered in a timely manner to ensure the accuracy of the pressing position and improve the automation and intelligence level of the pressing process.

[0034] In this embodiment, the cross-sectional profile of the pressing component 300 along the horizontal direction is fan-shaped. The fan-shaped cross-section design of the pressing component 300 creates an open space between adjacent pressing components 300, which facilitates the positioning gripper 220 to grasp and release the main reducing teeth. At the same time, the fan-shaped structure can evenly distribute the pressure to the surface of the main reducing teeth during pressing. Compared with the traditional columnar pressure head, it can reduce local stress concentration and avoid problems such as indentations and deformation on the surface of the workpiece 400, thus ensuring the pressing quality.

[0035] Furthermore, the outer side of the claw head 222 is curved; the curved design of the outer side of the claw head 222 matches the inner wall shape of the main reducing tooth inner ring, increasing the contact area between the two. During positioning and gripping, it can provide greater friction to prevent the main reducing tooth from slipping; at the same time, the curved surface fit can constrain the main reducing tooth from multiple directions, improving the stability and accuracy of positioning, and effectively preventing the workpiece 400 from shifting during gripping and pressing.

[0036] Preferably, there are three pressing components 300 and three positioning components 200, and the pressing components 300 and positioning components 200 are evenly distributed at 120-degree angles around the central axis of the connecting plate 100. The even distribution of the three positioning components 200 and the three pressing components 300 at 120-degree angles ensures that the main reducing gear is subjected to balanced force during positioning and pressing. The positioning gripper 220 positions the main reducing gear simultaneously from three directions, enabling automatic centering and ensuring that the workpiece 400 is in the center position. The pressing components 300 are evenly distributed and apply pressure synchronously, avoiding pressing tilt caused by uneven force and ensuring the coaxiality and perpendicularity of the main reducing gear after pressing.

[0037] The pressing component 300 and the positioning component 200 are arranged alternately, which optimizes the spatial layout. After the positioning gripper 220 grasps the main reducing tooth, the pressing component 300 can quickly and accurately reach the pressing position, reducing the risk of interference in the movement of the mechanism. At the same time, this layout ensures that the positioning and pressing actions do not interfere with each other, improving the smoothness and efficiency of the pressing process.

[0038] Specifically, the connecting plate 100 is provided with fastening holes 110 for fixed connection with the press and positioning grooves 120; the fastening holes 110 and grooves 120 on the connecting plate 100 achieve a stable connection and precise positioning with the press. The fastening holes 110 are fixed to the press with bolts, providing reliable connection strength and preventing the mechanism from loosening during the pressing process; the grooves 120 engage with the protrusions on the press, ensuring the accurate position of the connecting plate 100 during installation, guaranteeing the coaxiality of the pressing mechanism and the press, avoiding pressing offset due to connection errors, and improving pressing accuracy and stability.

[0039] In this embodiment, the pressing component 300 and the positioning component 200 are distributed at 30-degree intervals around the central axis of the connecting plate 100; the 30-degree interval between the pressing component 300 and the positioning component 200 further refines their spatial relationship. This layout allows the positioning gripper 220 to leave sufficient downward pressure space for the pressing component 300 after gripping the main reducing tooth, preventing collision and interference between the two; at the same time, the more precise angular distribution helps to transmit pressure more evenly to the main reducing tooth, further improving the stability and quality of pressing.

[0040] This main tooth-reducing press-fitting mechanism achieves efficient and precise press-fitting operations through integrated structural design and modular component collaboration. The overall workflow is as follows:

[0041] First, the connecting plate 100 is securely connected to the groove 120 and the press via the fastening hole 110, providing stable support for positioning and pressing. The distance sensor 500 monitors the distance between the mechanism and the workpiece 400 in real time and feeds the data back to the control system to precisely control the pressing speed and stroke of the press.

[0042] Upon entering the positioning stage, the positioning cylinder 210 radially extends and retracts, driving the positioning gripper 220 to move. The arc surface of the gripper head 222 fits against the inner ring of the main reducing gear. The connecting piece composed of the screw 223 and the elastic connecting rod 224 gives the gripper head 222 the ability to float. The three positioning grippers 220 are distributed at 120 degrees, automatically centering the main reducing gear from multiple directions to ensure that the workpiece 400 is in the center position.

[0043] During press-fitting, since the bottom surface of the press-fitting component 300 is higher than the positioning gripper 220, after positioning, the press drives the press-fitting component 300 to move downwards, and its fan-shaped cross section applies pressure evenly to the main reducing gear, avoiding stress concentration. The layout of the three press-fitting components 300 and the positioning component 200, which are alternately spaced and distributed at 30 degrees, ensures that the pressure is transmitted evenly and does not interfere with each other, thus achieving smooth press-fitting of the main reducing gear.

[0044] Throughout the process, the separate gripper design of the fixed seat 221, connector, and claw head 222 facilitates maintenance and replacement; the integrated structure simplifies the complex components of traditional sleeve-type tooling, reduces troubleshooting and maintenance time, effectively solves the problems of difficult positioning, complex structure, and low pressing accuracy in the existing technology, and significantly improves the efficiency and quality of main tooth pressing.

[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
