Abstract
The utility model provides an improved automatic chuck which is used for lathe work, which makes use of the centrifugal force as the source of power. The claw which is assembled on the chuck under the action of the inertia force tension mechanism through the lever transmission mechanism automatically clamps or automatically loosens manufacture workpieces. The utility model has the advantages of compact structure, convenient operation and reliability. The clamping or loosening of the workpieces can be realized without a spanner. The utility model is suitable for mass production and processing of parts of the shaft class of common lathes, special lathes or automatic lathes.
Description
The utility model relates to a kind of automatic chuck of improved turning processing usefulness.
Mechanical processing industry often adopts chuck to fix workpiece and is beneficial to finish various turning processing.Traditional three-jaw self-centering chuck is to utilize spanner, and the pinion that drives on the chuck rotates the spiral plate in the chuck, tightens up or unclamps processing work by chuck jaw.Workpiece for producing processing in enormous quantities blocks, gets workpiece repeatedly, has not only increased labor intensity of operating personnel, and has reduced operating efficiency.
The purpose of this utility model provides a kind of chuck of improved turning processing usefulness, and it is compact conformation not only, can realize self-centering, tighten automatically, and can alleviate labor intensity of operating personnel, increases work efficiency.
The purpose of this utility model is achieved in that the centrifugal force of generation when this device utilizes the chuck rotation as power source, makes the claw that is assembled on the chuck by bar thick stick transmission mechanism, tightens processing work under the effect of inertia force strainer automatically.When chuck is static, utilize the tightening force of the extension spring between inertia force strainer pouring weight, unclamp the processing work in the claw automatically.Chuck centering precision and claw fix the adjustment of processing work radial dimension, can be by the adjustable pad control in the claw, and the thickness of changing pad is easy to guarantee that the centering precision of chuck and claw tighten up processing work.
Because claw of the present utility model links by lever transmission mechanism and inertia force strainer, add man-hour so work as turning, workpiece can self-centering, chucking automatically.It has been cancelled traditional chuck and has utilized spanner to carry out the method for operating of clamping, has both alleviated labor intensity of operating personnel, has saved the loading, unloading time of clamping workpiece again, has improved operating efficiency effectively.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the front view of a kind of concrete structure of the present utility model.
Fig. 2 is the cutaway view of Fig. 1 along the A-A line.
Describe concrete structure of the present utility model in detail according to Fig. 1～2.This device comprises guard shield 1, fixedly spiral 2, chuck panel 3, chuck body 4, claw 7, lever transmission mechanism, inertia force strainer.The chuck panel 3 and the chuck body 4 that wherein are fixed with bearing 13 respectively are coupled to one by set bolt 2.Lever transmission mechanism is by passing through bearing pin 8 hinged poles 14, and push rod 9, drive rod 10 constitute.The extension spring 15 that the inertia force strainer comprises moving plate 12, is assembled in the pouring weight 11 on the moving plate 12 and pouring weight 11 is strained together.Uniform moving plate 12 is hinged on respectively by bearing pin 8 on the bearing 13 of chuck body 4, and the end of moving plate 12 is hinged by bearing pin 8 and drive rod 10 1 ends.Utilize bearing pin 8 to be hinged on the bearing 8 of connection holes, chuck panel 3 of claw 7 respectively with hinged push rod 9, the pole 14 of drive rod 10.The dop 5 that has curved surfaces is assembled on the claw 7 by adjustable pad 6, changes the thickness of pad 6, is easy to adjust the clamping degree of the centering precision and the workpiece of chuck.
During operation,, adjust the thickness of pad, make the space of the curved surfaces formation of dop 5 just insert workpiece at first according to the dimensional requirement of workpiece to be machined.During chucking work, its revolution can be controlled between 150～1200 rev/mins, and optimum revolution is 300～800 rev/mins.When workpiece rotates with chuck, the moving plate 12 of inertia force strainer rotates around bearing pin 8 under action of centrifugal force, and the drive rod 10 hinged with moving plate 12 promotes push rods 9, drive claw 7 and move, so the curved surfaces of dop just forms the clamping force that is enough to overcome cutting force to workpiece.Clamping force that the different revolutions of chuck form and the relation between the surmountable cutting force are by table 1 illustrate.Its surmountable cutting force is enough to satisfy the cutting requirement of workpiece such as the various carbon steels of cutting, steel alloy.
| Revolution rev/min | 300 | 450 | 600 | 800 |
| Clamping force kg | 181 | 429 | 773 | 1390 |
| Cutting force kg | 81 | 193 | 348 | 625 |
The utility model is suitable for the production in enormous quantities processing of the axostylus axostyle part of various engine lathes, special purpose lathe, automatic lathe, and is easy to operate, reliable. Cancel traditionally with spanner chucking, the operation of unclamping, as long as insert workpiece, rotary chuck can be realized automatic clamping; Stop chuck rotation, under the pulling force effect of extension spring 15, moving plate 12 sets back, and the dop 5 that drives claw 7 by lever transmission mechanism moves, and part can automatic loosening goes into operation.
The utility model is unsuitable for single-piece or small lot processing occasion, also is unsuitable for the processing of non-bar or special-shaped workpiece.
Claims (1)
