Abstract
The utility model relates to a workpiece positioning device for an edge grinding machine, in particular to a pneumatic backer for the edge grinding machine. The backer comprises a cylinder, a piston, an air inlet, a screw and a workpiece positioning rod, wherein threads are formed on the screw; the piston is arranged in the cylinder; the screw is connected with the piston; the piston drives the screw to move back and forth; a guide piece for making the screw axially rotate around the screw simultaneously when the screw moves back and forth is also arranged on the cylinder; the end of the guide piece is embedded into a thread groove of the screw; and the workpiece positioning rod is fixed on the part of the screw, which stretches out of the cylinder. The utility model has the advantages that: 1, the backer do 90-degree rotary motion, so that positioning height and a natural state vertical distance can be maximized; 2, the axial positioning clearance is small; and 3, after positioning work is finished, the backer is spirally retreated in the retreating process, so that friction between the backer and a workpiece is greatly reduced, and the service life is prolonged.
Description
Technical field
The utility model relates to the Working piece positioning device of edge polisher, the pneumatic backer of particularly a kind of edge polisher.
Background technology
The pneumatic backer's of edge polisher effect is to treat the workpiece of edging such as glass positions; Existing edge polisher backer adopts the piston in the cylinder directly to promote backstay, and the vertical mode of stretching out work top positions workpiece; After treating that workpiece machines; Cylinder drives backstay and moves down, and removes the location to workpiece.This edge polisher backer's defective is: backstay and workpiece will be reserved certain interval, cause positional accuracy poor, if the gap is too small, backstay is easy and workpiece generation friction in the process that rises and descend, defective work piece.
The utility model content
The utility model technical problem to be solved is: a kind of edge polisher backer is provided, improves positioning accuracy, avoid the infringement to workpiece.
The utility model solves the technical scheme that its technical problem adopted: the pneumatic backer of a kind of edge polisher; Comprise cylinder, piston, air inlet, screw rod and workpiece backstay; Have screw thread on the screw rod, piston is arranged in the cylinder, and screw rod is connected with piston; The piston actuated screw rod moves forward and backward; When screw rod moves forward and backward, make screw rod simultaneously around self axial guide of rotation also being provided with on the cylinder, guide is partially submerged into the screw flight groove, and the workpiece backstay is fixed on screw rod and stretches out on the part of cylinder.
Workpiece backstay and screw rod are fixing mutual vertically.
When piston was in initial position in cylinder, the position of workpiece backstay was parallel with table plane, and when piston forward moved to the operating position of setting, the position of workpiece backstay was vertical with the work stage plane.
The beneficial effect of the utility model is: 1. the backer makes 90 degree and rotatablely moves, and can realize that location height maximizing with the nature vertical range; 2. the axial location gap is little; 3. after the work of location, the backer does the spiral recession in the process of withdrawing from, greatly reduce the friction of backer and workpiece, increases the service life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified;
Fig. 1 is the sketch map that the pneumatic backer of the utility model is in original state;
Fig. 2 is the cutaway view that the pneumatic backer of the utility model is in original state;
Fig. 3 is the in running order sketch map of pneumatic backer of the utility model;
Fig. 4 is the in running order cutaway view of pneumatic backer of the utility model;
Among the figure, 1. cylinder, 2. piston, 3. air inlet, 4. screw rod, 5. workpiece backstay, 6. guide, 7. air supply opening.
The specific embodiment
Like Fig. 1,2, shown in 3 and 4, the pneumatic backer of a kind of edge polisher comprises cylinder 1, piston 2, air inlet 3, screw rod 4 and workpiece backstay 5; On cylinder, has air supply opening 7; Have screw thread on the screw rod 4, piston 2 is arranged in the cylinder 1, and screw rod 4 is connected with piston 2; Piston 2 drive screws 4 move forward and backward; When screw rod 4 moves forward and backward, make screw rod 4 simultaneously around self axial guide 6 of rotation also being provided with on the cylinder 1, guide 6 is partially submerged into the screw thread of screw rod 4, and workpiece backstay 5 is fixed on screw rod 4 and stretches out on the part of cylinder 1.Guide has various ways, like the guide post in Fig. 2 and 4, and perhaps spigot nut etc.
Like Fig. 1, shown in 2; When piston 2 was in initial position in cylinder 1, the position of workpiece backstay 5 was parallel with table plane, like Fig. 3, shown in 4; When piston 2 moved forward to the operating position of setting, the position of workpiece backstay 5 was vertical with the work stage plane.
