[0002] A reducer is an independent component consisting of a gear transmission, a worm transmission, or a gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It matches the speed and transmits torque between the prime mover and the working machine or actuator, and is widely used in modern machinery. During the assembly of the gear reduction mechanism, the gears and gear shafts need to be assembled. Manual operation will result in key components not being pressed into place, and it will also consume a lot of manpower, resulting in low assembly efficiency and failing to meet the needs of mass production.

For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0034] Example 1: As shown in the figure, the utility model includes: a support frame; a press-fitting assembly 1, located at the upper part of the support frame, including a punch head 5, which is driven by oil pressure and can move back and forth in the longitudinal direction to realize the press-fitting operation of the internal gear of the reducer; a body loading assembly 3, located on the side of the support frame, used to move the reducer to be assembled to the base structure 2 below the press-fitting assembly 1; the base structure 2, located at the lower part of the support frame and arranged relative to the press-fitting assembly 1.

[0035] The pressing assembly 1 also includes a hydraulic cylinder 9 for driving the punch head 5 to move back and forth in the longitudinal direction. The hydraulic cylinder 9 is installed on the upper part of the support frame and can move back and forth in the horizontal direction. In this example, the hydraulic cylinder 9 is installed on the positioning plate 6. The upper part of the support frame is provided with a guide rail 13 in the horizontal direction. The positioning plate 6 is slidably connected to the guide rail 13. The positioning plate 6 is connected to a driving assembly, and the driving assembly can drive the positioning plate 6 to move back and forth along the guide rail 13. Among them, the driving assembly includes a driving screw 10 that is rotatably connected to the upper part of the support frame, a driving block 11 that is threadedly connected to the driving screw 10, and a driving motor connected to one end of the driving screw 10. The driving motor is installed on the support frame, and the axis of the driving screw 10 is arranged horizontally. The driving block 11 is fixedly connected to the positioning plate 6.

[0036] The support frame includes two columns 4, with the machine body loading assembly 3 mounted on one of the columns 4. The machine body loading assembly 3 includes a connecting sleeve 18 mounted on the outside of the column 4, a chassis hanging plate 16 mounted on one side of the connecting sleeve 18, a counterweight structure 17 located on the other side of the connecting sleeve 18, and a rotating assembly connected to the connecting sleeve 18. In actual use, the reducer to be assembled is suspended from the chassis hanging plate 16 by hoisting or manual means and secured with bolts. After loading, the reducer is lifted by a lifting cylinder and rotated to the bottom of the press-fit assembly 1 via the rotating assembly. The lifting cylinder then lowers, placing the reducer to be assembled above the base structure 2. The press-fit assembly 1 completes the press-fitting process of the gears, gear shafts, bearings, etc. one by one through translation and stamping. A lifting plate 15 is rotatably connected to the upper portion of the connecting sleeve 18. The lifting plate 15 is connected to the lifting cylinder via a guide column 14.

[0039] Example 2: Based on the above-mentioned Example 1, wherein the base structure 2 is used to bear the force of the reducer to be assembled during the press-fitting process, and can be the base or chassis of a common press-fitting machine, with an area sufficient to place the reducer to be processed on it, or can be an embodiment disclosed in this example, wherein the base structure 2 includes a bottom plate 33, a pad 31 slidably connected to the top of the bottom plate 33 by a slide rail, and the pad 31 can be driven to adjust its position by a linear motor, a cylinder, etc. In this example, drive belts are provided on both sides of the pad 31, and the drive belts are powered by a drive wheel, and the two sides of the pad 31 are fixedly connected to the drive belts respectively. In addition, since the main shaft of some reducers is located below the box during the assembly process, it is preferred in this example, but not limited to, to open a clearance hole 30 on the pad 31 and a clearance channel 32 on the bottom plate 33 to make room for the main shaft of the reducer during the pressure-bearing process.

[0040] Example 3: Based on the above-mentioned Example 1, a pressure sensor 12 and a displacement ruler 7 can be further provided on the press-fitting assembly 1 to ensure that the parts are press-fitted in place. In this example, the pressure sensor 12 is preferably provided on the punch head 5. A transmission rod 8 is provided on one side of the punch head 5. The transmission rod 8 is provided vertically and passes through the positioning plate 6 and is slidably connected thereto. A displacement ruler 7 is provided on the support frame. The slider on the displacement ruler 7 is connected to the end of the transmission rod 8 and is used to record the displacement distance of the punch head 5.

[0041] The utility model moves the reducer to be assembled, which is hung on the chassis hanging plate, to the bottom of the press-fitting assembly through the cooperation relationship between the press-fitting assembly and the body loading assembly, and can be turned over according to processing requirements. The assembly operation is convenient and the assembly efficiency is higher. It can minimize the workload of workers, save time and effort for workers, and devote themselves to production more efficiently, reduce manpower input, reduce production costs, and create greater economic benefits for the enterprise.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
