DETAILED DESCRIPTION

[0024] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0025] Embodiment 1, in combination with the attached Figure 2-5 , an auxiliary loading and unloading structure for a milling machine, comprising a mobile frame 1 with a walking wheel 11 at the bottom and a swing rod 3. According to needs, the bottom surface of the mobile frame 1 is rectangular, and the corners of the bottom surface of the mobile frame 1 are provided with walking wheels 11; the top of the mobile frame 1 is rotatably connected to a driving shaft 2 arranged along its length direction, and the driving shaft 2 is fixedly sleeved with two swing rods 3 inclined up and down and arranged at intervals, and the opposite sides of the lower ends of the two swing rods 3 are rotatably connected to pins 4 that are transmission-matched with the driving shaft 2, and a horizontal bracket 5 for supporting a wheel seat is fixedly connected between the two pins 4;

[0026] Among them, the driving shaft 2 and the pin shaft 4 have the same rotation speed and opposite directions; it should be noted that: only when the driving shaft 2 and the pin shaft 4 are in transmission cooperation, the driving shaft 2 and the pin shaft 4 have the same rotation speed and opposite rotation directions.

[0027] The moving frame 1 is further provided with a driving device 6 for driving the driving shaft 2 to rotate.

[0028] It should be noted that: in the actual manufacturing process, the height of the drive shaft 2 is set to be approximately half the height of the wheel seat fixture (installed behind the milling machine workbench).

[0029] This setting can be achieved by pushing the attached Figure 2-3 The milling machine in this state is moved with the auxiliary loading and unloading structure, so that the horizontal bracket 5 moves to the bottom of the wheel seat to be processed, and then the driving device 6 is started. The driving device 6 drives the driving shaft 2 to rotate, and then drives the swing rod 3 to rotate. The rotation of the swing rod 3 drives the horizontal bracket 5 to move. At the same time, the driving shaft 2 also drives the pin shaft 4 to rotate, and the pin shaft 4 drives the horizontal bracket 5 to rotate. Since the driving shaft 2 and the pin shaft 4 have the same rotation speed and opposite direction, the horizontal bracket 5 is always in a horizontal posture until the wheel seat moves to the top of the wheel seat fixture installed on the milling machine workbench, as shown in the attached figure. Figure 5 The state shown in the figure, and then the milling machine is pushed to use the auxiliary loading and unloading structure to complete the loading operation of the auxiliary wheel seat. According to the above principle, the wheel seat unloading operation can also be completed, which solves the technical problem that the loading and unloading operation of the wheel seat with the help of the crane in the workshop affects the processing efficiency of the wheel seat.

[0030] Furthermore, the lower end of the swing lever 3 is provided with an outward bending portion 31, and the outer end of the bending portion 31 is provided with a pin shaft 4; the bending portion of the swing lever 3 is provided with a first transmission rod (32) that is transmission-coordinated with the drive shaft 2, and the position of the swing lever 3 close to the pin shaft 4 is provided with a second transmission rod 33 that is transmission-coordinated with the first transmission rod (32), and the second transmission rod 33 is transmission-coordinated with the pin shaft 4;

[0031] Among them, the drive shaft 2 and the first transmission rod (32), the first transmission rod (32) and the second transmission rod 33, and the second transmission rod 33 and the pin 4 have one or three sets of transmission cooperation with opposite rotation directions; that is, when the transmission direction of the drive shaft 2 and the first transmission rod (32), the transmission direction of the first transmission rod (32) and the second transmission rod 33, and the transmission direction of the second transmission rod 33 and the pin 4 have one or three sets of reverse transmission, it should be noted that: the above-mentioned reverse transmission can be understood as the opposite rotation direction.

[0032] In the example, the drive shaft 2 and the first transmission rod (32) can be matched through a sprocket set or a belt set; the first transmission rod (32) and the second transmission rod 33 can be matched through a sprocket set or a belt set; the second transmission rod 33 and the pin shaft 4 can be matched through a gear set.

[0033] This arrangement enables the angle between the bent portion 31 of the swing arm 3 and the horizontal bracket 5 to be smaller when the wheel seat is close to the bottom surface or the wheel seat fixture.

[0034] Furthermore, an anti-skid groove 51 is provided on the top surface of the horizontal bracket 5 at a position corresponding to the wheel seat axle sleeve; such a setting can limit the wheel seat axle sleeve through the anti-skid groove 51 to prevent the wheel seat from moving relative to the horizontal bracket 5 and causing the wheel seat to fall, thereby increasing the safety factor.

[0035] Furthermore, a clearance gap 52 is provided in the middle of one side of the horizontal bracket 5 close to the movable frame 1; when the middle part of the wheel seat clamp has a structure supporting the wheel seat, the clearance gap 52 is used for avoidance, ensuring that the loading and unloading operations of the auxiliary wheel seat proceed normally.

[0036] Embodiment 2, combined with the attached Figure 2-5 , an auxiliary loading and unloading structure for a milling machine, based on the first embodiment, an outward extension portion 12 is provided in the middle of both sides of the bottom surface of the mobile frame 1, and a walking wheel 11 is also provided at the outer end of the bottom surface of the extension portion 12; such an arrangement can increase the ground width of the mobile frame 1, prevent the mobile frame 1 from tipping over, and further improve the safety factor.

[0037] As required, in order to further prevent the mobile frame 1 from tipping over, a counterweight may be provided at the bottom of the mobile frame 1 .

[0038] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
