Technical field
The utility model relates to the Robotics field, especially a kind of end clamp as robot.
Background technology
Robot is widely used in modern industry, and for enhancing productivity, the liberation labour improves product quality, has outstanding effect.The end clamp of robot is the executing agency of operation workpiece, and different workpiece may need to use different anchor clamps.The polishing of the grinding workpieces of watch case and so on is the together very important operation of machining, the sanding and polishing of traditional watch case and similar five metals, plastics part, by manually finishing by simple and mechanical, the precision of polishing is difficult to control, uniformity is bad, and percent defective is high, and is dangerous, efficient is low and can not satisfy mechanization, automation, the needs of scale of mass production.The precision instruments such as current wrist-watch are badly in need of the processing that a kind of industrial robot is finished watchcase and so on workpiece in producing, thus also just a kind of end clamp for robot of needs carry out the workpiece of clamping watch case and so on and operate accordingly.
The utility model content
The purpose of this utility model is to overcome the problem of above-mentioned deficiency, and a kind of precision of grinding workpieces is provided, easily control, high conformity, percent defective is low, safety, high efficiency especially can satisfy mechanization, automation, the end clamp that is used for robot that scale of mass production needs.
The technical solution adopted in the utility model is such:
A kind of end clamp for robot, comprise chuck, it is characterized in that: the outer end of described chuck is the apical grafting tension type chuck with inner cone cavity, the inner of chuck is the holder with cylindrical cavity, coaxially in chuck be built-in with the push rod that a front end is cone, the rear end of push rod links to each other with a thrust bearing device, thrust bearing device is located in the thrust metal, thrust metal is connected with the piston push rod of a cylinder, piston push rod seesawing vertically drives the push rod motion, apical grafting tension type chuck is opened or clamps.
Between described thrust bearing device and described thrust metal, be provided with spring washer.
Be provided with the chuck cover outside described chuck, push rod and thrust bearing device, the inner of chuck cover and the end cap of described cylinder are fastenedly connected.
Be provided with the spring bearing of push rod between described chuck and thrust bearing device, push rod and spring bearing are rotationally connected by a bearing block, and the inner of described chuck is threaded with bearing block.
Between the inner of described chuck and described bearing block, be provided with screw.
On the outer end of described chuck cover, removably be connected with a dust ring.
Described chuck cover is connected with screw by ring flange with described cylinder.
Described thrust metal is connected threadably with the piston push rod of described cylinder, is provided with holding screw therebetween.
Be provided with cylinder block at described cylinder.
Operation principle of the present utility model is: the workpiece of watch case and so on is put on the end face of chuck, robot or other mechanical device promote thrust bearing device by the cylinder piston push rod, and then the drive push rod travels forward, chuck radially opens because being subject to the axial thrust of push rod, make Workpiece clamping, when being attached on the surfaces of revolution of polishing wheel when the watch case surface, because the direction of rotation of watchcase end face and polishing wheel is angled, so polishing wheel can drive the watchcase rotation, reach the purpose of polishing.This device volume is little, and is lightweight, and it is also very convenient to change chuck, only need to turn on dust ring, and the holding screw on the chuck that comes loose namely can screw out chuck to change.Clamping force exists tension to cross loose problem scarcely.The utility model can be used as the part of robot, as the end of robot, is used for clamping operation the sanding and polishing of watchcase and so on workpiece is processed, and has the machining accuracy height, high conformity, percent defective is low, safety, efficient is high, is fit to mechanization, automation, the characteristics of scale of mass production.
Below in conjunction with drawings and the specific embodiments the utility model is described further.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Shown in Fig. 1:
The end clamp that is used for robot, comprise chuck 1, the outer end of chuck 1 is by along 2 of axle center five equilibrium with the apical grafting tension type chuck 101(of inner cone cavity, 3 or 4 fixture blocks consist of, referring to known drilling attachment structure), the inner of chuck 1 is the holder 102 with cylindrical cavity, at the chuck 1 interior coaxial push rod 2 that a front end is cone that is built-in with, the rear end of push rod 2 links to each other with a thrust bearing device 3, thrust bearing device is located in the thrust metal 4, thrust metal 4 is connected with the piston push rod 5 of a cylinder 11, is provided with the spring washer 16 of its damping, buffering effect between thrust bearing device 3 and described thrust metal 4.Piston push rod seesawing vertically can drive push rod 2 motion corresponding sports, it is opened and clamping work pieces near apical grafting tension type chuck 101 forward, retreat away from 101 of apical grafting tension type chucks and can put into workpiece, when being attached on the surfaces of revolution of polishing wheel when the outer surface of the workpiece that watch case and so on will polish, because the direction of rotation of its end face and polishing wheel is angled, when polishing wheel rotates, can drive the watchcase rotation, thereby reach the purpose of polishing.In addition, as supporting and protection mechanism, also be provided with chuck cover 6 outside chuck 1, push rod 2 and thrust bearing device 3, the inner of chuck cover 6 and the end cap 17 of cylinder are fastenedly connected.Also be provided with the spring bearing 7 of push rod 2 between chuck 1 and thrust bearing device 3, push rod 2 is rotationally connected by a bearing block 8 with spring bearing 7, and the inner of chuck 1 is threaded with bearing block 8.Between the inner of chuck 1 and described bearing block 8, also be provided with screw 9.Outer end at chuck cover 6 arranges dismountable dust ring 10, is convenient to dustproof and the dismounting chuck.
