[0002] At present, most of the positioning pin automatic feeding machines on the market use a material pipe for feeding and adopt a feeding method from directly above vertically. In this way, the positioning pins are kept in a vertical state. After feeding, they need to be sent to the engine block for press-fitting. However, the front and rear end faces of the engine block are in a horizontal posture, and the press-fitting posture of the positioning pins is inconsistent with the required press-fitting posture of the engine block, so the requirement of press-fitting the front and rear two end faces at the same station cannot be realized. Most of the existing technical solutions choose to change the posture of the engine block during press-fitting, directly perform vertical press-fitting after feeding, and realize the press-fitting of the vertical posture of the two-sided positioning pins by adding stations or using a robot to flip the engine block 180 degrees at the station. However, this will lead to an increase in production costs and a decrease in work efficiency. Content of the Utility Model

[0020] The present utility model will be further described below by way of examples, but the present utility model is not limited to the scope of the described examples.
[0021] Example
[0022] As Figures 1-3As shown in the figure, this embodiment provides an automatic feeding device for the rotation of a positioning pin. The automatic feeding device includes a guide sleeve 1, a mounting block 2, a rotating shaft 3, a transition plate 4, and a material pipe 5; the guide sleeve 1 is attached to the end face of the engine block through the mounting block 2; the transition plate 4 is connected to the mounting block 2, and the transition plate 4 is used to connect a rotating cylinder 6; the rotating shaft 3 is connected to the rotating cylinder 6 through a connecting block 7; the material pipe 5 is vertically arranged on the mounting block 2 and is used for feeding the positioning pin.
[0023] As Figure 1 shown in the figure, in this embodiment, the mounting block 2 is a hexahedron mounting block, the guide sleeve 1 and the rotating cylinder 6 are mounted on adjacent sides of the mounting block 2, and the material pipe 5 is mounted above the mounting block 2. Specifically, the material pipe 5 is vertically fixed above the mounting block 2 through screws and its own spigot positioning. The positioning pin is fed into the top port of the material pipe 5 and slides along the material pipe 5 into the interior of the mounting block 2, and then falls on the rotating shaft 3 in a fixed vertical posture. The posture of the positioning pin is changed by the rotation of the rotating shaft 3, so that the positioning pin rotates into a horizontal posture to achieve the press-fitting of the engine block. A baffle 11 is also provided on the mounting block 2, and the baffle 11 is mounted on the opposite end of the rotating cylinder 6 and is used as a cover plate for the rotating shaft 3.
[0024] As Figures 2-3 shown in the figure, in this embodiment, the rotating cylinder 6 is fixed on the transition plate 4 through screws, and the connecting block 7 is mounted on the rotating flange of the rotating cylinder 6 through screws. The rotating flange drives the rotating shaft 3 to rotate. Specifically, in this embodiment, the rotating cylinder 6 adopts an SMC rotating cylinder. The SMC rotating cylinder is a device that converts pneumatic energy into mechanical energy. Its working principle is to make the internal piston move back and forth through air pressure control, so as to achieve the rotation effect. The rotating shaft 3 is connected to the rotating flange of the SMC rotating cylinder through the connecting block 7. A flat key is used to connect the rotating shaft 3 and the connecting block 7 at a fixed angle. Under the action of the rotating flange, the rotating shaft 3 rotates, driving the positioning pin falling on the rotating shaft 3 to rotate.
[0025] As Figure 2 shown in the figure, in this embodiment, a guide shaft 8 is provided in the guide sleeve 1, and the guide shaft 8 is perpendicular to the rotating shaft 3. Specifically, the guide shaft 8 is set perpendicular to the rotating shaft 3, and the coaxiality is ensured through two bearings. Under the action of the rotating cylinder 6, the rotating shaft 3 and the guide shaft 8 rotate, driving the positioning pin in a vertical posture falling from the material pipe 5 to rotate by 90 degrees and present a horizontal posture to achieve the press-fitting posture required by the engine block.
[0026] As Figure 3As shown, in this embodiment, the automatic feeding device further includes an adjusting pad 9, which is arranged between the mounting block 2 and the guide sleeve 1 and is used to adjust the distance between the engine block and the guide sleeve 1. Specifically, the adjusting pad 9 and the guide sleeve 1 are fixed together on the press-fitting side of the mounting block 2 by screws, and are used to actually adjust the distance between the guide sleeve 1 and the engine block at the press-fitting site, so as to ensure the accuracy of the engine block press-fitting and improve the work efficiency of the press-fitting.
[0027] As Figure 3 shown, in this embodiment, the mounting block 2 is also provided with a stud 10, which is arranged on the opposite side of the material pipe 5 and is used to adjust the height of the positioning pin. Specifically, a stud 10 is also provided at the bottom of the mounting block 2, and the positioning pin is fed from the material pipe 5 and lands on the stud 10; the stud 10 uses a combination of bolts and nuts to adjust the height of the positioning pin for feeding the material pipe 5; by rotating the nut, the bolt is screwed into the mounting block 2 to adjust the height of the positioning pin, so as to ensure the accuracy of the engine block press-fitting positioning pin.
[0028] This embodiment provides an automatic feeding device with a rotating positioning pin. The automatic feeding device rotates the positioning pin in a vertical posture automatically fed through the material pipe to a horizontal posture by setting a rotating cylinder and a rotating shaft, so as to achieve the required press-fitting posture of the engine block, and thus perform the final press-fitting of the engine block. The utility model can realize the simultaneous press-fitting of positioning pins on the front and rear end faces of the engine block at the same station, saving the labor, material and time costs of production and improving the production work efficiency.
[0029] The working principle of the utility model is as follows: The guide sleeve 1 of the automatic feeding device is attached to the engine block, and the adjusting pad 9 is adjusted according to the distance from the engine block to ensure that the guide sleeve 1 is attached to the engine block. The material is automatically fed by the material pipe 5. When the positioning pin is fed to the press-fitting punch through the material pipe 5, it lands on the rotating shaft 3. The rotating cylinder 6 is opened, and the rotating cylinder 6 works to drive the rotating shaft 3 to rotate, which can drive the positioning pin to rotate 90 degrees from the vertical posture to the horizontal posture to achieve the required press-fitting posture of the engine block, and thus perform the final press-fitting of the engine block.
