Description

Technical Field

[0001] This utility model relates to the field of speed reducer assembly technology, and in particular to a press-fitting device for axle main speed reducer assembly. Background Technology

[0002] As the power transmission mechanism in new energy vehicles, the reducer requires high assembly precision. Bearings are a crucial component in ensuring power transmission through the shaft system; good assembly precision can effectively improve transmission efficiency and reduce noise.

[0003] Chinese Patent No. CN221110591U discloses a speed reducer press-fitting device. This device includes a support plate for supporting the housing, a positioning plate for positioning the bearing outer ring and positioning pin, a press head mechanism, and a limiting pin. The positioning plate is located above the support plate and has positioning holes and a positioning seat. The device simultaneously controls the downward movement of the press head mechanism to press-fit the bearing outer ring and oil seal, and controls the downward movement of the limiting pin to press-fit the positioning pin. The limiting pin limits the downward displacement of the press head mechanism. This technical solution features high press-fitting efficiency, accurate positioning, simple and convenient operation, simple structure, adaptability to different pressing forces, and high safety.

[0004] However, the above technical solution has the following shortcomings: the reducer is pressed from bottom to top one by one during the press-fitting process, so some parts can be press-fitted on an assembly line. However, this technical solution is difficult to increase the production speed of the reducer assembly through assembly line press-fitting, and the labor intensity of workers is high. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a pressing device that uses a drive component to make a rotating disk drive the housing to rotate at multiple angles in sequence, and then uses a feeding component and a pressing component to press multiple parts one by one onto the housing from bottom to top.

[0006] The present invention provides a press-fitting device for a main reducer assembly of a vehicle axle, comprising: a frame on which a top frame and an intermediate bearing are mounted, a rotating disk on which a driving component is connected, and a plurality of fixed columns and threaded rods distributed in a ring at the top of the rotating disk; multiple placement racks evenly arranged in a ring on the rotating disk, the multiple placement racks being distributed on the multiple fixed columns and threaded rods respectively; multiple pressing components arranged in a ring on the top frame; and multiple feeding components arranged in a ring on the frame.

[0007] Preferably, the placement rack includes a base plate portion that contacts multiple fixed columns and threaded rod portions, and a fixing block portion disposed on the base plate portion; the threaded rod portion is threadedly connected with bolts, and the threads abut against the base plate portion.

[0008] Preferably, multiple fixed columns are provided with elastic rings.

[0009] Preferably, the pressing assembly includes a motor a mounted on the frame, an adjusting bracket mounted on the output end of motor a, a motor b mounted on the adjusting bracket, a lead screw mounted on the output end of motor b, a movable block threaded onto the lead screw, and an electric cylinder mounted on the movable block.

[0010] Preferably, an intermediate bearing b is connected between the bottom end of the top frame and the top end of the adjusting frame.

[0011] Preferably, the feeding assembly includes a limiting frame mounted on the frame, a movable frame in contact with the limiting frame, a motor c mounted on the movable frame, a lifting assembly mounted at the output end of the motor c, and mechanical claw assemblies distributed near the movable frame.

[0012] Preferably, the number of shelves is always an even number.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] In use, according to the specifications of the reducer, multiple mounting brackets of corresponding specifications are fixed to the rotating disk with evenly spaced bolts. The driving component drives the rotating disk to rotate through a transmission structure such as gear meshing. The rotating disk moves in alternating states of stopping and moving. After the housing is placed on the rotating disk, a component is placed on the housing and then pressed. The pressing and placement of components are staggered to avoid pressing multiple components at the same time, which would result in low pressing quality. Furthermore, the feeding component and the pressing component work together to realize the automated process of press-fitting the reducer. Components that cannot be automatically installed are installed manually by workers, thereby reducing the workload of workers. Attached Figure Description

Detailed Implementation

[0019] Example 1

[0020] like Figures 1-3 As shown in this embodiment, a press-fitting device for axle main reducer assembly includes a frame 1, placement racks 6, a pressing assembly 3, and a feeding assembly. The frame 1 is equipped with a top frame 2 and an intermediate bearing 5. A rotating disk 4 is mounted on the intermediate bearing 5 and connected to a driving component. The top of the rotating disk 4 has multiple fixed posts and threaded rods distributed in a ring. Multiple placement racks 6 are evenly distributed along a ring on the rotating disk 4, with each rack located on one of the fixed posts or threaded rods. Multiple pressing assemblies 3 are arranged along a ring on the top frame 2. Multiple feeding assemblies are arranged along a ring on the frame 1. The number of placement racks 6 is always even.

[0021] In this embodiment, according to the specifications of the reducer, multiple mounting brackets 6 of the corresponding specifications are fixed to the rotating disk 4 with uniformly spaced bolts along the ring. The driving component drives the rotating disk 4 to rotate through a transmission structure such as gear meshing. The moving state of the rotating disk 4 is a combination of stopping and moving. After the housing 11 is placed on the rotating disk 4, a component is placed on the housing 11 and then pressed. The pressing and placement of components are distributed alternately, thereby avoiding the low pressing quality caused by pressing multiple components at the same time. Furthermore, the feeding component and the pressing component 3 work together to realize the automated process of press-fitting the reducer. The intermediate parts that cannot be automatically installed are installed manually by workers, thereby reducing the workload of workers.

[0022] Example 2

[0023] like Figure 1 and Figure 2 As shown in the figure, this embodiment proposes a pressing device for axle main reducer assembly. Compared with the first embodiment, in this embodiment, the placement frame 6 includes a base plate 61 that contacts multiple fixed columns and threaded rods, and a fixing block 62 disposed on the base plate 61. Bolts 10 are threadedly connected to the threaded rods, and the bolts 10 abut against the base plate 61. After changing the placement frame 6 of different specifications according to different sizes of reducers, the size of the base plate 61 remains unchanged. However, the size and number of fixing blocks 62 are changed according to the changes in the surface of the reducer housing, thereby restricting the movement of different housings 11 during pressing. Since the size of the base plate 61 remains unchanged, the center point of the top of the base plate 61 can be used as the origin to locate the coordinate system, allowing the device to locate different points on the reducer through the coordinate system, reducing the difficulty of automated pressing of the reducer.

[0024] Multiple fixed columns are provided with elastic rings 12. When the base plate 61 is fixed, the elastic rings 12 can reduce the hard contact between the base plate 61 and the fixed columns when the base plate 61 moves, thereby reducing the wear of the fixed columns or the base plate 61.

[0025] Example 3

[0026] like Figure 1 and Figure 3 As shown, this embodiment proposes a press-fitting device for axle main reducer assembly. Compared to Embodiment 1, in this embodiment, the pressing component 3 includes a motor a31 mounted on the frame 1, an adjusting frame 32 mounted on the output end of the motor a31, a motor b33 mounted on the adjusting frame 32, a lead screw 34 mounted on the output end of the motor b33, a movable block threaded onto the lead screw 34, and an electric cylinder 35 mounted on the movable block. The motor a31 drives the adjusting frame 32 to rotate, thereby adjusting the distribution angle of the lead screw 34 at the output end of the motor b33. Then, the motor b33 drives the lead screw 34 to move the movable block, allowing the electric cylinder 35 to move to any point within a range with the length of the adjusting frame 32 as its diameter. This avoids dead angles during the press-fitting process of the reducer. The connection point between the output end of the motor a31 and the adjusting frame 32 is reinforced to improve the connection strength.

[0027] An intermediate bearing b36 is connected between the bottom end of the top frame 2 and the top end of the adjusting frame 32. When pressing the item, the electric cylinder 35 applies downward pressure, and the contact surface with the electric cylinder 35 applies the same reaction force towards the electric cylinder 35. The intermediate bearing b36 can further transmit the reaction force to the top frame 2, thereby preventing the adjusting frame 32 from bending under the action of the reaction force.

[0028] Example 4

[0029] like Figure 1 and Figure 2 As shown in this embodiment, a pressing device for axle main reducer assembly is proposed. Compared with Embodiment 1, in this embodiment, the feeding component includes a limiting frame 7 set on the frame 1, a moving frame 8 in contact with the limiting frame 7, a motor c9 set on the moving frame 8, a lifting component set at the output end of the motor c9, and mechanical claw components distributed near the moving frame 8. A central control system is set on the frame 1. When the central control system drives the rotating disk to rotate, the mechanical claw components place the parts stored inside the moving frame 8 onto the housing 11. The precise gripping and placement of parts can be achieved by pre-setting the coordinate system of the moving frame 8 and the housing 11 according to the specifications of the reducer. The coordinate system allows the mechanical claw components to move to a position where they can be gripped and placed, thereby enabling the equipment to automatically place parts onto the housing 11 and reducing the workload of workers.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
