[0044] The third embodiment is based on the first and second embodiments. Figures 9 to 11As shown, the fitting clamp 4 includes a clamping frame 41, a side frame 42 is fixedly installed on the outer surface of the clamping frame 41, two side frames 42 are provided, a bending plate 43 is fixedly installed between the opposite surfaces of the two side frames 42, an extrusion pad 44 is fixedly installed on the surface of the bending plate 43, a swivel 47 is rotatably installed on one side of the outer surface of the bending plate 43, an opening and closing ring 45 is rotatably installed on the surface of the bending plate 43 through the swivel 47, an adjusting card 46 is rotatably fixedly installed on the opening and closing ring 45, and two groups of the adjusting card 46 are provided, and the two groups of the adjusting card 46 are frictionally adapted to the bending plate 43 through the opening and closing ring 45. The clamping frame 41 is installed on the outside of the slide plate 11. When the staff moves the slide plate 11, the clamping frame 41 is driven to move to the outside of the frame 9, and then the staff opens the opening and closing ring 45, and clamps the main shaft inside the bending plate 43 and the opening and closing ring 45.

[0049] The clamping frame 41 is installed on the outside of the slide plate 11. When the staff moves the slide plate 11, the clamping frame 41 is driven to move to the outside of the frame 9, and then the staff opens the opening and closing ring 45, and clamps the main shaft inside the bending plate 43 and the opening and closing ring 45. When the opening and closing ring 45 is closed, the extrusion pad 44 installed on the surface of the bending plate 43 is squeezed by the main shaft and deformed and tightly attached to the bending plate 43. The adjustment clamps 46 installed on both sides of the opening and closing ring 45 are clamped on both sides of the main shaft to straighten and limit the main shaft, improve the stability of the main shaft and the gear box when pressed together, so as to avoid wear of the main shaft when it slips in the fitting clamp 4 during pressing.

[0050] When the first hydraulic cylinder 1 drives the pressing assembly 2 downward to punch the main shaft, the main shaft clamped in the bending plate 43 and the opening and closing ring 45 slides downward under pressure, and the extrusion pad 44 attached to the outside of the main shaft increases the friction force when the main shaft slides down, so as to avoid the main shaft from tipping over during pressing and affecting the assembly accuracy.

[0051] The bent pads 462 and the corrugated plates 464 installed on both sides of the opening and closing ring 45 are made of flexible rubber material and are easily deformed to cover the surface of the main shaft when clamping the main shaft. When deformed, they extend outward to the gap of the opening and closing ring 45 to facilitate fitting with main shafts of different models. After the main shaft is inserted into the gear box, the clamp 46 is adjusted to rebound and reset, and is clamped above the main shaft to prevent the main shaft from retreating after the pressing assembly 2 is lifted, thereby improving the convenience of installation.

[0053] The staff places the gear box body in the mounting seat 3, and sleeves the gear box on the outside of the inner support member 84. When assembling the gear box and the main shaft, the staff starts the second hydraulic cylinder 5, so that the second hydraulic cylinder 5 is lifted upward and drives the inner support member 84 to move upward through the support plate 83. At this time, the gear box sleeved on the inner support member 84 is supported by the second hydraulic cylinder 5 and pressed and assembled with the main shaft pressed down by the first hydraulic cylinder 1. The pressure in the upper and lower directions is used to improve the assembly efficiency, so that the assembly between the main shaft and the gear box is tighter.

[0054] The gearbox body is placed in the mounting seat 3. Since the interior of the gearbox body is hollow during processing, a positioning groove compatible with the main shaft is opened on the top. When the gearbox is installed, the inner wall and the inner support plate 844 generate friction, so that the inner support plate 844 rotates on the surface of the sliding ring 846 according to the gearbox model, so that multiple groups of inner support plates 844 are fitted and supported on the inner wall of the gearbox, so that the gearbox is supported and limited to avoid the gearbox from shifting during assembly.
