Technical Field

[0001] The utility model relates to the technical field of mechanical devices, in particular to a rotary positioning device. Background Art

[0002] In order to improve the efficiency during the processing of the workpiece, a rotating disk is often set up. There are two stations on the rotating disk. One is facing the processing station to process the workpiece, such as polishing the workpiece, and the other is at the loading station where the operator loads the material. After the workpiece at the current station is processed, the rotating disk is needed to swap the two stations. In this case, it is generally not necessary to use a motor to drive the rotating disk to rotate. The motor drive is expensive and the structure is complex. Therefore, in order to save costs, a manual rotating disk will be considered. At this time, it involves the limiting and positioning of the rotating disk to avoid the position mismatch after the rotating disk is converted, which affects the processing quality.

[0003] The purpose of the utility model is to provide a rotation positioning device which can achieve the above-mentioned limiting and positioning purposes. Utility Model Content

[0007] When the force acts on the inclined surface from the right side, the positioning plate rotates counterclockwise. After the force disappears, the positioning plate automatically returns to its original position under the action of gravity. When the force acts on the positioning reference surface of the positioning plate from the left side, the positioning plate remains stationary and plays a positioning role.

[0008] Furthermore, the bottom surface of the positioning plate includes the installation reference surface and an avoidance surface, and the avoidance surface is located on the left side of the installation reference surface.

[0028] The following is a specific embodiment of the present invention, and those skilled in the art can easily understand the advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented in other different ways, that is, different modifications and changes can be made without departing from the scope disclosed by the present invention.

[0029] The position descriptions such as left and right in this embodiment are based on the orientations in the drawings and have no special meanings and are not used to limit the protection scope of the present utility model.

[0030] Embodiment: A rotation positioning device, such as Figures 1 to 6 As shown, the rotary positioning device is installed at the edge of a rotating disk 20, and the rotating disk is provided with two stations 201 for installing tooling.

[0031] The rotation positioning device includes two fixed seats 1 and a positioning plate 2, and the fixed seats are fixedly installed on the workbench 10; the positioning plate is located between the two fixed seats and is rotatably connected to the two fixed seats through a pin shaft 3, and the bottom surface 21 of the positioning plate includes an installation reference surface 211 and an avoidance surface 212, and the avoidance surface is located on the left side of the installation reference surface.

[0032] The upper end of the positioning plate is the top surface; the top surface is an inclined surface with one end high and the other end low, the side where the inclined surface is located is defined as the right side, and the other side is the left side, and the center of gravity of the positioning plate is on the right side of the pin shaft; the back side 23 of the positioning plate is the positioning reference surface;

[0033] like Figure 4 As shown, when the force acts on the inclined plane from the right side (arrow A indicates the direction of the force), the positioning plate rotates counterclockwise. After the force disappears, the positioning plate automatically returns to its original position under the action of gravity (shown by the dotted line); when the force acts on the positioning reference surface of the positioning plate from the left side (arrow B indicates the direction of the force), the positioning plate remains stationary and plays a positioning role (shown by the solid line).

[0034] In this embodiment, the inclination angle α of the top surface is 10 to 40°. This inclination angle range is preferred, and the return of the positioning plate and the rotation process around the pin shaft are relatively smooth without jamming. Other angle ranges are also acceptable.

[0035] In this embodiment, the fixing seat and the workbench are both provided with mounting holes 11, and the fixing seat is mounted on the workbench by the cooperation of the fasteners and the mounting holes. To facilitate the installation of the fixing seat, other mounting structures are also possible, as long as the fixing seat can be mounted on the workbench.

[0036] In this embodiment, the rotation positioning device is a metal part, which is wear-resistant and not easy to be damaged.

[0037] The working principle and working process of this utility model:

[0038] Under the action of gravity, the lower side of the positioning plate is installed on the reference mounting surface of the workbench. The back side is the positioning reference surface to ensure the accurate positioning of the rotating disk. Figure 1 He Ru Figure 5 shown.

[0039] like Figure 6 As shown in the figure, when the rotating disk rotates clockwise (with the center of the rotating disk as the rotation center), the inclined surface of the positioning plate will drop under the pressure of the rotating disk. This ensures that the rotating disk passes smoothly. After the rotating disk rotates, the positioning plate will rotate clockwise (with the pin as the rotation center) under the force of gravity to return to the original state, that is, the installation reference surface is against the surface of the workbench.

[0040] like Figure 4 As shown, the dotted line represents the state and position of the positioning plate when the rotating disk rotates clockwise; the solid line represents the state and position of the positioning plate when the rotating disk rotates counterclockwise.

[0041] The above description is only an embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the specification and drawings of the present utility model, or directly or indirectly used in other related technical fields, is also included in the patent protection scope of the present utility model.
