It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
As shown in fig. 1 to 5, an embodiment of the present application provides a multi-angle turnover mechanism, including a base 1 and a cantilever 2 disposed on the base 1, the multi-angle turnover mechanism further includes: the rotating shaft 3 is hinged to the lower end of the base 1, and a connecting rod 31 extends out of the rotating shaft 3 along the radial direction of the rotating shaft; a driving device 4 connected to the rotary shaft 3 to drive the rotary shaft to rotate; the balance cylinder 5 comprises a cylinder body 51, the cylinder body 51 comprises a cylinder barrel 511 and a cylinder output shaft 512 which is arranged in the cylinder barrel 511 and moves in a telescopic mode relative to the cylinder barrel 511, the cylinder barrel 511 is provided with a front air cavity 513 which drives the cylinder output shaft 512 to retract when air enters, the cylinder barrel 511 is hinged to the cantilever 2, and the cylinder output shaft 512 is hinged to the connecting rod 31. The rotating shaft 3 can drive the overturned object to overturn when rotating, the balance cylinder 5 is connected with the rotating shaft 3 through the connecting rod 31 to bear part or all of the load borne by the rotating shaft 3 when rotating, so that the driving device 4 can complete the overturning action only by extremely small driving force, and the driving device 4 can stably overturn at any angle due to extremely small torque required by the driving device 4, preferably at any angle between 0 and 90 degrees from the initial position, and the multi-angle overturning mechanism has a compact structure, light dead weight and large overturning load.
Correspondingly, the driving device 4 comprises a servo motor 41, a speed reducer 42, a first gear 43 and a second gear 44, the servo motor 41 is fixed on the outer side of the base 1, an output shaft of the servo motor 41 extends into the base 1 and is connected with the speed reducer 42, an output shaft of the speed reducer 42 extends out of the other outer side of the base 1 and is connected with the first gear 43, the first gear 43 is meshed with the second gear 44, and the second gear 44 is connected with the rotating shaft 3. The connection mode of the speed reducer and the servo motor can be the following two modes: in the holding mode, an output shaft of the servo motor extends into the speed reducer, and the servo motor is connected with the speed reducer through a flange. A deformable hoop is arranged in the speed reducer, and the hoop can hold the shaft of the servo motor tightly by operating a locking screw on the speed reducer; the connection is carried out in an external coupling mode, the external coupling is adopted in the connection mode, servo electricity is needed, a key groove is arranged, and the external coupling can adopt a flexible coupling. When the load is large, it is not cost-effective to increase the power of the servo motor, so that the servo reducer with the speed reduction ratio suitable for the required speed range is selected, and the servo motor and the reducer can increase the torque. Further, by setting the gear ratio of the first gear 43 to the second gear 44 to be smaller than 1, the transmission ratio of the servo motor can be further increased, and the driving torque of the driving device can be further increased. In addition, the servo motor is combined with the balance cylinder, so that the high-precision performance of the motor is compatible, and the high-load advantage of the cylinder is compatible.
In this implementation, the multi-angle turnover mechanism further comprises a floating joint 6, wherein one end of the floating joint 6 is fixed to the cylinder output shaft 512, and the other end of the floating joint is hinged to the connecting rod 31.

As shown in the schematic diagram of the balancing cylinder shown in fig. 5, the balancing cylinder 5 further includes: an air-controlled pressure reducing valve 52, an air outlet of which is communicated with the front air cavity 513; the two-position three-way reversing valve 53 is provided with a first reversing air inlet 531, a second reversing air inlet and a reversing air outlet, and the reversing air outlet is connected with the air inlet of the pneumatic control pressure reducing valve 52; a first pilot reducing valve 54, an air outlet of which is connected to the first direction-changing air inlet 531; a second pilot pressure reducing valve 55; the outlet of which is connected to the second reversing inlet 532; and the air source 56 is connected with the air inlet of the pneumatic control pressure reducing valve 52, the first reversing air inlet and the second reversing air inlet. The principle of the balancing cylinder 5 is as follows: the first pilot pressure reducing valve 54 and the second pilot pressure reducing valve 55 serve as pilot valves that control the heavy load balance and the no load balance, respectively. The pilot pressure reducing valve determines the inlet pressure of the pneumatic pressure reducing valve 52 by a preset air pressure, i.e., reflecting the preset heavy load and no-load weight. The two paths of pilot gas are introduced into a two-position three-way reversing valve 53 for switching heavy load balance and no-load balance, the gas of a gas source 56 passes through the two-position three-way reversing valve 53 by a pilot reducing valve and then is introduced into a pneumatic reducing valve 52, and the pressure of an outlet of the pneumatic reducing valve 52 is equal to the pressure of the corresponding pilot reducing valve. The gas of the gas source 56 is decompressed by the pneumatic control pressure reducing valve 52 and then is introduced into the front gas chamber 513 of the cylinder 5, and the piston of the cylinder body is retracted after the gas is filled in the front gas chamber 513, so that part of driving force required by load overturning is borne. One of the balance states is that the force in the retraction direction of the piston of the cylinder body is equal to the component force of the load in the opposite direction, and at this time, the load can be easily turned over only by a small external force, and if the turning is clockwise turning, and then the balance is broken by counterclockwise turning, for example, when the external force is used for counterclockwise turning, the piston of the cylinder body extends outwards, the pressure in the cylinder rises at this time, and exceeds the set pressure of the pilot pressure valve (the set pressure is the pressure in the balance), and the redundant pressure is discharged from the discharge port of the pneumatic control pressure reducing valve 52. The result of such a process is: the piston load is extended to a certain position and is still, and the pressure in the cylinder body is restored to the previous balance pressure. Conversely, a clockwise rollover breaks the in-cylinder pressure balance, causing the pneumatic controlled pressure relief valve 52 to re-establish equilibrium with the injection of air into the forward air chamber 513. By utilizing the principle, the working efficiency can be improved, and the torque born by the motor can be reduced. And the structure is simple, the number of components is small, and the manufacturing cost is low.

Specifically, the origin sensor is a photoelectric sensor or a position sensor. The signal that this origin sensor detected both can directly regard as spacing signal in order to restrict the position of axis of rotation, can provide the signal source for automated control to realize more accurate control.
In this embodiment, a load mounting plate 32 that performs a turning operation as the rotating shaft 3 rotates is connected to the rotating shaft 3, and a plurality of mounting holes for mounting a jig or a load are provided in the load mounting plate 32.
