Embodiment Construction
[0007] The technical solution of the present invention will be further described below with reference to the accompanying drawings.
[0008] A three-degree-of-freedom polar coordinate type pneumatic manipulator, consisting of 1 base, 2 swivel cylinders, 3 swivel turntables, 4 pitch cylinders, 5 photoelectric detection devices, 6 columns, 7 telescopic cylinders, and 8 grippers, the columns and pitch cylinders are installed On the turntable, the telescopic cylinder is connected with the column and the pitch cylinder through hinges to form a four-bar linkage mechanism. The claw is installed on the cylinder rod of the telescopic cylinder, and the turntable is connected with the rotary cylinder in the base. The infrared photoelectric sensor is installed on the cylinder, and the transmission grating is fixed on the cylinder rod.
[0009] The pitching cylinder converts the linear motion of the cylinder into the pitching motion of the manipulator around the horizontal axis through the...

The invention relates to a three-degree-of-freedom polar coordinate type pneumatic manipulator. The three-degree-of-freedom polar coordinate type pneumatic manipulator comprises a base, a rotation air cylinder, a rotary table, a pitching air cylinder, a photoelectric detector, an upright, a telescopic air cylinder and a paw. The upright and the pitching air cylinder are mounted on the rotary table, the telescopic air cylinder is connected with the upright and the pitching air cylinder through hinges, the paw is mounted on a cylinder rod of the telescopic air cylinder, the rotary table is connected with the rotation air cylinder in the base, the photoelectric detector is composed of an infrared photoelectric sensor and a transmission type raster, the infrared photoelectric sensor is mounted on the air cylinder body, the transmission type raster is mounted on the cylinder rod and is driven to move to generate photoelectric signal pulse along with moving of the cylinder rod, and the controller judges whether an arm moves in place or not according to photoelectric signals fed back to the input end and then controls moving and stopping of the air cylinder, so optional positioning of the manipulator can be realized. Accordingly, the three-degree-of-freedom polar coordinate type pneumatic manipulator has the advantages of low cost, convenience in maintenance and high universality.
Description
technical field [0001] The invention relates to the technical field of manipulators, in particular to a three-degree-of-freedom polar coordinate pneumatic manipulator. Background technique [0002] With the wide application of manipulator technology, general-purpose manipulators with independent controllers, flexible actions, and suitable for small and medium-sized batches of automated production have developed rapidly. At present, the driving methods of general-purpose manipulators mostly adopt electric drive and hydraulic drive. Motor-driven manipulator control Good performance, quick response, and precise positioning, but it is not conducive to fire and explosion protection, and the cost is high; the driving force of the manipulator in the hydraulic drive mode is large, but it needs to be equipped with a hydraulic system, the system is complex, easy to leak, and pollute the environment; there are many pneumatic manipulators As a special manipulator, it is designed for spe...
