As shown in fig. 1 to 3, a floating constant force device for a deburring apparatus, a floating constant force device 3, includes a first transition plate 301, a vertical plate 302, a linear slide rail 303, a baffle 304, a bracket 305, a rolling screw 306, a fixing plate 307, a cylinder 308, a push rod connecting block 309, and a pressure sensor 310; a first transition plate 301 is arranged at the end part of the five-axis robot, a vertical plate 302 is vertically arranged on the first transition plate 301, a linear slide rail 303 is arranged on the vertical plate 302, baffle plates 304 are fixedly arranged at two ends of the vertical plate 302, a support 305 is fixedly arranged on the baffle plates 304, a ball screw is arranged on the support 305, two ends of the ball screw are simultaneously fixed on the support 305, a fixing plate 307 is arranged on the ball screw, an air cylinder 308 is arranged on the fixing plate 307, a push rod connecting block 309 is arranged at the deep-contraction end of the air cylinder 308, and a pressure sensor 310 is arranged on the air cylinder 308.
The vertical plate 302 is convex, and a round hole with the diameter communicated with the diameter of the ball screw is arranged in the middle of the vertical plate 302. The push rod connecting block 309 is arranged in a C shape, and one surface of the push rod connecting block 309 is provided with four threaded holes at least used for fixing the second transition plate.
In a further example, the floating constant force device 3 is fixedly connected to one end of a five-axis robot, the double-acting cylinder 308 is mounted on the fixing plate 307, and the basic principle of the floating constant force mechanism is that a push rod connecting block 309 of the double-acting cylinder 308 is fixedly connected to a base of the belt sander, and the cylinder 308 moves on a ball screw through the expansion and contraction of a push rod of the double-acting cylinder 308, so that the belt sander body is driven to reciprocate on the linear sliding block. In the process, the force sensor arranged on the air cylinder 308 senses the pressure of the air cylinder 308, the pressure signal is converted into a discrete signal through the A/D converter, and after the PLC control system reads the signal, the pressure value of the air cylinder 308 is compared with a preset pressure value to perform force compensation, so that passive force control is realized. This unsteady constant force device 3 has realized that pressure is invariable and controllable between work piece and the emery wheel at the in-process of polishing, so compare in traditional polishing equipment, this mechanism application scope is wider and more safe and reliable. In the work of polishing, this mechanism and robot communicate each other, and to the robot of some work pieces that the surface is complicated polish, the subassembly of polishing can float according to the work piece surface condition, guarantees to polish between subassembly and the work piece and grinds the invariable of throwing power to realize the unanimity of work piece grinding volume.
In a further example, the floating constant force device 3 controls the linear motion mechanism to move forward and backward according to real-time change of pressure in the grinding assembly cutting direction during workpiece grinding, and realizes constant grinding and polishing force between the workpiece and the grinding assembly and five-axis robot through reciprocating motion of the linear motion mechanism. And the real-time processing of the pressure change of the workpiece and the grinding in the cutting normal direction and the accurate force feedback, so that the pressure sensor 310 and the proportional valve are designed to work cooperatively to realize the control of the grinding displacement and the grinding and polishing force. And the man-machine interaction interface is used for facilitating the operation of an operator on the belt sanding platform.
In a further example, during the grinding and polishing process, the five-axis robot communicates with the PLC in real time, and the PLC is used for controlling the operation of each actuating mechanism. The floating constant force device 3 of the mechanism mainly controls the action of the cylinder 308 through the proportional valve and the pressure sensor 310 to realize the force balance of the mechanism, and the control process of the control system is as follows:
1) setting a pressure target value and storing the pressure target value in an I/O port of the industrial robot;
2) the PLC controller obtains the opening of the electric proportional valve by reading the information in the I/O, thereby controlling the output force of the air cylinder 308 and further controlling the floating constant force mechanism;
3) the display is used for displaying the current set pressure value and the pressure value of the air cylinder 308;
4) and circulating the steps.
In a further example, the floating constant force device 3 achieves the floating of the mechanism through a cylinder 308 fixed on a ball screw. One end of the grinding assembly is connected with the push rod of the air cylinder 308 through the second transition plate, and when the push rod of the air cylinder 308 moves, the grinding assembly reciprocates along the linear slide rail 303. In the polishing process, the air cylinder 308 controls the proportional valve through a communication mode of outputting analog quantity by a PLC system, and the proportional solenoid valve reads input information to control the output air pressure of the air cylinder 308. When the PLC system detects that the pressure between the workpiece and the grinding is deviated from a preset value, the air cylinder 308 is controlled to give a proper pushing force to the grinding assembly. The specific implementation process is that when the polishing force of the workpiece and the polishing assembly is greater than a set value, the pneumatic pressure valve automatically releases pressure to reduce the driving force; when the polishing force is smaller than the set value, the air pressure in the air cylinder 308 is reduced, and the pressure is supplemented through the proportional valve to increase the pushing force of the air cylinder 308. Through this passive power control device, can realize that the pressure between work piece and abrasive band remains stable, at the in-process of polishing, five robots can real-time adjustment output pressure of active control proportional valve, can realize the adjustment of the different pressure of polishing in same work piece different positions, and the effect of polishing promotes by a wide margin, has promoted the efficiency of polishing.
