[0023] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.
[0024] This embodiment provides a force-controlled grinding device comprising a manipulator 1, a fixture 2, and a pulse dust collector 3. The manipulator 1 is mounted on one side of the fixture 2, which secures the workpiece to be ground and cooperates with the manipulator 1 for grinding. The pulse dust collector 3 is connected to a dust collection duct 4, which is in communication with a dust hood 5. The dust hood 5 is mounted below the fixture 2 to collect grinding debris.
[0025] The fixing device 2 includes a platform 6 and a support block 7. A rectangular protective cover 10 is provided on the top of the platform 6, and the bottom of the platform 6 is supported on the ground. The four support blocks 7 are connected end to end to form a rectangular fixed frame 8. Each support block 7 is provided with a positioning groove 9. The polishing piece is placed on the support block 7, and the bottom of the polishing piece is inserted into the positioning groove 9 for positioning. The purpose of this arrangement is to make the polishing pieces placed in sequence uniform in placement and the polished products have the same shape. The rectangular fixed frame 8 is arranged on the inner side of the rectangular protective cover 10, and the rectangular fixed frame 8 and the rectangular protective cover 10 are fixedly connected by a connecting column 11. The height of the rectangular protective cover 10 is higher than the rectangular fixed frame 8. During polishing, the rectangular protective cover 10 blocks the debris thrown out in the horizontal direction, thereby improving the safety of polishing. 90° rotating cylinders 12 are installed at the four corners between the rectangular fixed frame 8 and the rectangular protective cover 10 to limit the polishing piece. During use, the 90° rotating cylinder 12 is controlled to rotate so that the limiting portion on the rotating cylinder is rotated and fixed above the grinding piece for limiting.
[0026] In some embodiments, connecting plates 13 are secured beneath rectangular mounting brackets 8. Each connecting column 11 is vertically connected to connecting plates 13 and rectangular protective cover 10 at both ends. The secure connection between rectangular mounting bracket 8 and rectangular protective cover 10 via connecting plates 13 extends the service life of rectangular mounting bracket 8 and prevents damage to rectangular mounting bracket 8 during disassembly and maintenance.
[0027] In some embodiments, adjustment feet 14 are provided around the bottom of the stand 6 . The adjustment feet 14 are existing products. The stand 6 is installed with the adjustment feet 14 to adjust the height of the stand 6 to match the grinding accuracy of the robot 1 .
[0028] In some embodiments, multiple exhaust connectors 15 are spaced apart on the outside of each support block 7. Each exhaust connector 15 is connected to an external electrical control cabinet via an exhaust pipe. This arrangement serves to absorb air between the polishing piece and the support block 7, reducing the air pressure between the polishing piece and the support block 7 to a value lower than the ambient air pressure. This ensures that the polishing piece is stably fixed to the support block 7, improving the precision of the polishing piece.
[0029] In some embodiments, the force-controlled grinding apparatus further includes a button box 16 and a bracket 17. Bracket 17 is mounted near fixture 2, and button box 16 is mounted on bracket 17. Button box 16 is electrically connected to pulse dust collector 3, robot 1, and 90° rotary cylinder 12. This arrangement facilitates flexible operator control of pulse dust collector 3, robot 1, and 90° rotary cylinder 12.
[0030] In some embodiments, the 90° rotating cylinder 12 includes a pressing block 19. The cylinder rotor of the 90° rotating cylinder 12 is vertically fixed to the pressing block 19. The rotation of the rotor drives the pressing block 19 to rotate until it is limited above the grinding piece to prevent the grinding piece from moving.
[0031] In some embodiments, the force-controlled grinding device further includes a grating. Multiple gratings are connected end to end to form a fence 20, which is provided around the manipulator 1, the fixture 2, and the pulse dust collector 3 to form an isolation zone to prevent the force-controlled grinding device from causing harm to people.
[0032] Furthermore, the force-controlled grinding equipment also includes an automatic door 21, infrared detectors, and a controller. Multiple infrared detectors are spaced apart on the fence 20, along with the automatic door 21. The controller is electrically connected to the automatic door 21 and the infrared detectors. When a person approaches the fence 20, the infrared detectors transmit a detection signal to the controller, which then closes the automatic door 21, preventing the person from entering the fence 20 and improving the safety of the force-controlled grinding equipment.
