[0002] The clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed to the rear plane of the flywheel with screws. The output shaft of the clutch is the input shaft of the gearbox. When the car is driving, the driver can step on or release the clutch pedal as needed to temporarily separate and gradually engage the engine and gearbox to cut off or transmit the power input from the engine to the transmission.

[0003] The existing clutch hub press-fitting frame adopts a threaded rod and a clamping plate. By rotating the threaded rod, the end of the threaded rod pushes the clamping plate to move, so that the fixed clamping plate and the movable clamping plate are brought closer to each other, and then the outer surface of the clutch component is clamped. Because the clamping plates do not move relative to each other, the clutch component is not centered after clamping, so that it is not vertically aligned with the outer hub to be pressed below, but is in a horizontal misalignment. In order to improve the accuracy of press-fitting, a clutch hub press-fitting frame is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a clutch hub press-fitting rack, which has the advantage of accurate press-fitting position.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-2 A clutch hub press-fitting frame includes a workbench 1, a support frame 2 is fixedly installed on the top of the workbench 1, a linear module 3 is installed on the support frame 2, and a mounting frame 4 is provided on the linear module 3, which can drive the mounting frame 4 to move laterally. The mounting frame 4 is slidably connected to the rear side wall of the support frame 2, and a mounting shell 5 is fixedly installed on the bottom of the mounting frame 4.

[0020] Among them, a placing table 10 is fixedly installed on the top of the workbench 1 and on the inner side of the support frame 2, which is used to place the pressure plate, active friction plate, driven steel plate and gear hub for press-fitting work. A clamping column 11 is fixedly installed on the top of the workbench 1 and on the outer side of the placing table 10. There are three clamping columns 11. An outer hub 12 is placed on the top of the workbench 1. The outer hub 12 is located between the three clamping columns 11. The outer hub 12 can be positioned to avoid displacement of the outer hub 12 during the press-fitting process, which may lead to inaccurate press-fitting.

[0021] In addition, a pressing assembly 8 is provided on the mounting frame 4, and the pressing assembly 8 includes a hydraulic cylinder 81 and a pressing plate 82. The hydraulic cylinder 81 is fixedly installed on the top of the mounting frame 4, and the pressing plate 82 is fixedly installed at the output end of the hydraulic cylinder 81. When the hydraulic cylinder 81 is extended, the pressing plate 82 moves downward to perform the pressing work. A guide rod 9 slidingly connected to the mounting frame 4 is fixedly installed on the top of the pressing plate 82, which is used to guide the pressing plate 82 so that the pressing plate 82 can move vertically up and down as much as possible.

[0022] See also Figure 1-4 A centering clamping assembly 6 for adaptively clamping the clutch components is provided on the mounting shell 5. The centering clamping assembly 6 includes a servo motor 61, a movable shaft 62, a gear 63, an inner ring gear 64, an eccentric wheel 65, a movable cover 66 and a positioning block 67. The servo motor 61 is fixedly mounted on the top of the mounting shell 5, and the movable shaft 62 is rotatably connected between the top wall and the opposite side of the bottom wall of the mounting shell 5. The gear 63 is fixedly mounted on the output shaft of the servo motor 61 and the outer surface of the movable shaft 62. The inner ring gear 64 is rotatably connected to the inner side wall of the mounting shell 5. The gear 63 is internally meshed with the inner ring gear 64. When the servo motor 61 is started, the gear 63 on the output shaft drives the inner ring gear 64 to engage and rotate, and the inner ring gear 64 engages with the gears 63 on multiple movable shafts 62, thereby allowing multiple movable shafts 62 to rotate, gradually realizing adaptive centering clamping of the clutch components.

[0023] The eccentric wheel 65 is fixedly mounted on the outer surface of the movable shaft 62 and can rotate along the movable shaft 62. The axis of the eccentric wheel 65 deviates from the axis of the movable shaft 62, that is, the axis of the eccentric wheel 65 and the axis of the movable shaft 62 are not in the same straight line. The movable cover 66 is slidably connected to the bottom wall of the mounting shell 5. The eccentric wheel 65 is movably connected to the inner wall of the movable cover 66. The rotation of the eccentric wheel 65 can push the movable cover 66 to move closer to or away from the clutch component. The bottom of the mounting shell 5 is fixedly mounted with a slide rail 7 slidably connected to the movable cover 66, which can move along the outer surface of the slide rail 7 to clamp or release the clutch component. The shape of the slide rail 7 is an inverted T shape. The positioning block 67 is fixedly mounted on the end of the movable cover 66. Under the push of the movable cover 66, the three positioning blocks 67 can adaptively clamp the outer surface of the clutch component in the center, and can also make the three positioning blocks 67 move away from the clutch component to release it. The shape of the positioning block 67 is V-shaped.

[0024] When this embodiment is in use, the outer hub 12 is placed between the three clamping columns 11, and then the pressure plate or active friction plate or driven steel plate or gear hub placed on the placement table 10 is moved between the three positioning blocks 67, and the servo motor 61 is started. Under the mutual meshing transmission of the gear 63 and the inner ring gear 64, the eccentric wheel 65 rotates and pushes the movable cover 66 to move along the outer surface of the slide rail 7. The three positioning blocks 67 move toward the pressure plate or active friction plate or driven steel plate or gear hub to clamp and fix it. As the linear module 3 is started, the pressure plate or active friction plate or driven steel plate or gear hub moves to the top of the outer hub 12, and the servo motor 61 is started in reverse. The three positioning blocks 67 release the pressure plate or active friction plate or driven steel plate or gear hub and insert it into the outer hub 12. The linear module 3 is started, and the pressure plate 82 is moved to the top of the outer hub 12. The hydraulic cylinder 81 is started, and the pressure plate 82 presses the pressure plate or active friction plate or driven steel plate or gear hub.

[0025] The beneficial effects of the above embodiment are:

[0026] The clutch hub press-fitting frame is provided with a centering clamping assembly 6. After the centering clamping assembly 6 is used, under the start of the servo motor 61 and the mutual engagement transmission of the gear 63 and the inner ring gear 64, multiple movable shafts 62 are rotated together, driving the rotating eccentric wheel 65 to push the movable cover 66 toward the outer surface of the clutch component, so that multiple positioning blocks 67 can clamp and fix the clutch component together, realizing the centering clamping of the clutch component by the positioning blocks 67 and improving the accuracy of the clutch hub press-fitting.
