[0017] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0018] like Figure 1-3 A fixture flip angle detection mechanism shown in the figure includes a fixture seat 1, on which is provided a clamping assembly 2 for fixing a workpiece to be processed, and a power source 3 for driving the clamping assembly 2 to rotate, a rotating shaft 4 is provided at the output end of the power source 3, and a directional cam 5 is provided on the rotating shaft 4, and the end of the rotating shaft 4 opposite to the power source 3 is connected to the clamping assembly 2, and the fixture seat 1 is provided with a sensing member 6 located below the directional cam 5, and when the outer end point of the directional cam 5 (not specifically a point, but a protruding part of the outer end where the point is located) corresponding to the maximum value directly or indirectly contacts the sensing member 6, the workpiece is in a vertical state, and in this embodiment, the sensing member 6 is a contact sensor or a micro switch, etc.

[0019] The transmission member is configured as a directional cam 5, and when the outer end point of the directional cam 5 (i.e., the outermost end of the transmission member) corresponding to the maximum value of the outer contour of the directional cam 5 and the line connecting the center of the directional cam 5 directly or indirectly contacts the sensing member 6, the workpiece is in a vertical state. In addition to the directional cam 5, a strip rod or a strip plate, or other special-shaped structures can also be used, as long as the outermost end of the transmission member contacts the cam bearing 7 to drive the movable rod 10 to press down.

[0020] When the outer end point of the directional cam 5 directly or indirectly contacts the sensing element 6, the sensing element 6 will send a sensing signal to the controller. At this time, the workpiece is in a vertical state, the power source 3 stops driving, and the fixture can easily enter the channel of the RGV trolley.

[0021] A cam bearing 7 which can contact the directional cam 5 is provided on the clamp seat 1 and the cam bearing 7 is located below the directional cam 5. The cam bearing 7 cooperates with the directional cam 5 to form a cam motion pair. A mounting seat 8 is fixed in the clamp seat 1. A cam seat 9 for mounting the cam bearing 7 is provided in the mounting seat 8. A movable rod 10 is fixedly connected to the bottom of the cam seat 9 and the movable rod 10 is passed through the mounting seat 8. A return spring 11 is provided on the outer sleeve of the movable rod 10 and the two ends of the return spring 11 are respectively abutted against the bottom of the cam seat 9 and the bottom of the mounting seat 8. The sensing element 6 is located at the lower end of the movable rod 10.

[0022] Specific working method: the outer end point of the directional cam 5 corresponding to the maximum value of the line connecting the outer contour of the directional cam 5 and the center of the directional cam 5 touches the cam bearing 7, so that the cam seat 9 presses down the reset spring 11 and drives the lower end of the movable rod 10 to touch the sensing part 6, and the sensing part 6 generates a sensing signal and sends it to the controller. At this time, the reducer stops rotating and the workpiece is adjusted to a vertical state.

[0023] The clamp seat 1 includes a support frame 12, a bearing seat 13 is arranged at the upper end of the support frame 12, the power source 3 is fixed on the support frame 12 and the rotating shaft 4 of the power source 3 is passed through the bearing seat 13 and connected to the clamping assembly 2, the movable rod 10 slides vertically in the support frame 12, and the clamping assembly 2 in this embodiment is the prior art, and there are many locking methods, which are irrelevant to the improvement points of this application, so they are not specifically elaborated. In this application, the sensor 6 is located at the lower end of the movable rod 10, that is, the bottom of the support frame 12, and the upper end of the support frame 12 can reduce wiring and make the layout more reasonable.

The mounting seat 8 includes a U-shaped connecting plate 15 and a baffle 16. The upper ends of both sides of the U-shaped connecting plate 15 are respectively provided with bending plates 17. The bending plates 17 are located outside the opening 14 of the support frame 12 and are erected on the upper end surface of the support frame 12. The mounting seat 8 can be quickly positioned to achieve quick installation.

[0025] The power source 3 is a reducer, and one end of the input shaft of the reducer is provided with a handwheel 18 for manual control, and the other end of the input shaft of the reducer is provided with a split coupling 19 that cooperates with the motor to realize electric operation. If it is controlled by the handwheel 18, the outermost end of the directional cam 5 needs to be manually adjusted to the position of the cam bearing 7. At this time, the indicator light is on, or the controller displays an in-place signal. The principle of electric control is the same. In this embodiment, how to control the rotation of the reducer by the motor is not the focus of this application. The operation can be performed on the controller (not shown in the figure). This application does not involve programming improvements, so it is not specifically elaborated.

[0026] The above shows and describes the basic principle, main features and advantages of the utility model.
