[0020] The present utility model will be further described below with reference to the accompanying drawings in specific embodiments. See Figure 1-2 :

[0021] A press-fitting device for the crank of a vegetable cutter, comprising a workbench 1, a press-fitting base 2 is arranged on the workbench 1, a press-fitting die 3 is arranged on the press-fitting base 2, the outer end of the press-fitting die 3 is hinged to the outer end of the press-fitting base 2, a first power device 5 for driving the press-fitting die 3 to turn outwards along the hinge shaft 4 is arranged between the workbench 1 or the press-fitting base 2 and the press-fitting die 3, a plurality of press-fitting cavities 6 adapted to the cranks to be press-fitted are arranged on the press-fitting die 3, a pressing plate 8 driven by a second power device 7 to move up and down is arranged above the press-fitting die 3, and the pressing plate 8 is arranged parallel to the press-fitting die 3 and covers all the press-fitting cavities 6.

[0022] During use, the cranks to be press-fitted (including the upper cover body and the lower cover body of the crank pre-assembled together) are sequentially placed into the press-fitting cavities 6, then the second power device 7 is started, the second power device 7 drives the pressing plate 8 to move downwards, and the press-fitting of the crank is completed when the pressing plate 8 abuts against the press-fitting die 3. Then the second power device 7 drives the pressing plate 8 to reset upwards, the first power device 5 is started, the press-fitting die 3 turns outwards around its hinge shaft 4, and during the turning process, the press-fitted cranks will automatically pour out from the press-fitting cavities 6 and fall into the receiving frame below. When the blanking is completed, the first power device 5 drives the press-fitting die 3 to reset.

[0023] In this embodiment, the press-fitting die 3 and the press-fitting base 2 are hinged by a plurality of hinges, and the hinges are respectively installed on the outer sides of the press-fitting die 3 and the press-fitting base 2; the press-fitting base 2 is fixed on the workbench 1 by fasteners, the press-fitting die 3 and the press-fitting base 2 have matching shapes, and their outer sides are located in the same vertical plane.

[0024] A pair of control buttons 9 for jointly controlling the start and stop of the press-fitting device are arranged on the workbench 1, the control buttons 9 are arranged at intervals and are respectively operated by the left and right hands. When starting the press-fitting device, both hands need to operate the two control buttons 9 simultaneously. Therefore, it can be ensured that when the press-fitting device is started, both hands are not within the working area.

[0025] A working area for press-fitting is formed between the above-mentioned pressing plate 8 and the press-fitting die 3. A sensor 10 for sensing the entry of a human body into the working area is arranged at the edge of the working area. The sensor 10 is electrically connected to the controller of the press-fitting device. The sensor 10 adopts a device in the art that can sense a human body, especially a hand, such as a proximity switch, an infrared sensor, an opposed sensor, etc. When the sensor 10 senses a human body, the press-fitting device cannot be started (including the first power device 5 and the second power device 7).

[0026] In this embodiment, the sensor 10 is a grating sensor. The grating sensor is installed on one side of the working area close to the control button 9. In this embodiment, both the control button 9 and the grating sensor are arranged on the left or right side of the working area, and the first power device 5 is arranged on the opposite side. Preferably, the grating sensors are respectively arranged on the workbench 1 and the cylinder mounting seat 11. When a hand accidentally extends into the working area, the grating sensor will immediately generate a sensing, and then control the press-fitting device to stop, preventing safety accidents. In addition, when a hand is operating in the working area, it can also ensure that the press-fitting device is in a stopped state.

[0027] Compare with the attached Figure 2 In this embodiment, the flipping structure of the press-fitting die 3 is that the first power device 5 is a first cylinder arranged obliquely. The cylinder body of the first cylinder is hinged to the workbench 1, and the piston rod is hinged to the side of the press-fitting die 3. The first cylinder drives the press-fitting die 3 to flip by an angle greater than 90°. Further, a hinge seat for installing the cylinder body of the first cylinder is arranged on the workbench 1, and a fixed pin hinged to the piston rod of the first cylinder is arranged on the side of the press-fitting die 3. When the piston rod of the first cylinder extends, the press-fitting die 3 rotates outward around its hinge axis 4. When the piston rod of the first cylinder retracts, the press-fitting die 3 rotates inward around its hinge axis 4.

[0028] The specific structure of the second power device 7 in this embodiment is: the second power device 7 is a second cylinder arranged vertically. The cylinder body of the second cylinder is installed on the cylinder mounting seat 11, and the piston rod of the second cylinder body passes through the cylinder mounting seat 11 and is fixedly connected to the pressing plate 8.

[0029] Further, a column 12 is arranged on the workbench 1, and the cylinder mounting seat 11 is slidably arranged axially on the column 12. Further, the cylinder mounting seat 11 is driven to adjust the axial position up and down and locked by a handwheel and a screw mechanism.

[0030] A device for detecting the displacement of the piston rod of the second cylinder is provided on the second cylinder, such as a proximity switch, etc. In this embodiment, the proximity switch is arranged at the rear side of the cylinder block of the second cylinder. A vertically arranged sliding rod is connected above the pressing plate 8. The sliding rod penetrates upward through the cylinder mounting seat 11 and is arranged corresponding to the proximity switch. When the pressing plate 8 moves upward, the sliding rod moves upward accordingly. When the proximity switch detects the sliding rod, the movement stops.
