Description
Technical field
The present invention relates to a kind of jig for machining, particularly a kind of fixture with spinfunction.
Background technology
In machining process, clamping to workpiece is extremely important, particularly on automatic assembly line, fixture commonly used mostly is the oil cylinder clamping mode at present, be provided with the oil cylinder joined with hydraulic control on clamp body, the piston rod external end head matched with oil cylinder connects the chuck of clamping work pieces, and oil cylinder drives chuck and moves, by chuck, with the cushion block on clamp body, matched, holding workpiece.Sometimes workpiece is subject to the restriction of other clamping and positioning element and conveying in Working position, fixture, and the phenomenon of interfering with other parts often occurs the chuck of existing traveling priority, solves interference and bothers very much, causes complex structure, takes up room large.
Summary of the invention
The purpose of this invention is to provide and a kind ofly make that the fixture overall structure is simple, chuck has spinfunction, can avoid other parts, prevent that interference from occurring, flexible movements are reliable, the little fixture with spinfunction that takes up room, overcome the deficiencies in the prior art.
Fixture with spinfunction of the present invention, comprise clamp body, be provided with cylinder barrel in clamp body, the first piston left side matched with cylinder barrel forms the first oil pocket and is communicated with the first turnover oil nozzle, the right side of first piston forms the second oil pocket and is communicated with the second turnover oil nozzle, and the external end head of the piston rod matched with first piston connects chuck; In described cylinder barrel, right part also is furnished with the second piston, the second piston right side forms the 3rd oil pocket with cylinder barrel and is communicated with the 3rd turnover oil nozzle, the second piston inner hole is communicated with described the second oil pocket, endoporus top that the right-hand member of described piston rod stretches to the second piston are processed with plane, be connected with the first pin on the second piston, the middle part of the first pin just is positioned on described plane, and the two ends of the first pin are inserted on the second piston; The left part outside at the second piston is processed with helicoid, and helicoid is stuck on the second pin, and the two ends of the second pin are inserted on cylinder barrel.
Described helicoid processing is on the second piston left part lower half circle outer surface.
Fixture with spinfunction of the present invention, during action, three oil pockets cooperatively interact, can make chuck move on rectilinear direction, also can make chuck do the motion of rotation, prevent that interference from occurring, the fixture overall structure is simplified, take up room little, flexible movements are reliable, and two pistons cooperatively interact and can realize the action of larger stroke, are more suitable for the clamping in various workpieces.
The accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention;
Fig. 2 is the structural representation of the second piston shown in Fig. 1.
The specific embodiment
As shown in Figure 1: 1 is clamp body, is provided with cylinder barrel 4 in clamp body 1 and is fixedly connected with by screw.Be furnished with mutually first piston 22 with cylinder barrel 4, the left end of cylinder barrel 4 is fixedly connected with left transparent cover 19 by screw, and left transparent cover 19 is positioned at clamp body 1 endoporus termination.Form the first oil pocket 2 in first piston 22 left sides and be communicated with the first turnover oil nozzle 3.
The right side of first piston 22 forms the second oil pocket 6 and is communicated with the second turnover oil nozzle 8.The piston rod 18 matched with first piston 22 stretches out and external end head is connected by screw chuck 17 from the centre bore of left transparent cover 19.The nut 5 that has been threaded on piston rod 18, nut 5 is for to first piston 22 axial limitings.
The outside that the interior right part of cylinder barrel 4 also is furnished with the second piston 12, the second pistons 12 is set with right transparent cover 13, between the right-hand member head of right transparent cover 13 and cylinder barrel 4, by screw, is fixedly connected with.The second piston 12 right sides form the 3rd oil pocket 10 with cylinder barrel 4 and are communicated with the 3rd turnover oil nozzle 11.The second piston 12 endoporus are communicated with the second oil pocket 6.Endoporus top that the right-hand member of piston rod 18 stretches to the second piston 12 are processed with plane 7.The middle part that is connected with the first pin 9, the first pins 9 on the second piston 12 just is positioned on plane 7, and the two ends of the first pin 9 are inserted on the second piston 12.The right-hand member head of the second piston 12 is fixed with right end cap 14 by screw.
End face at clamp body 1 is provided with cushion block 15.
As shown in Figure 2: the left part outside at the second piston 12 is processed with helicoid 21, and helicoid 21 processing are on the second piston 12 left part lower half circle outer surfaces.Helicoid 21 is stuck on the second pin 20, and the two ends of the second pin 20 are inserted on cylinder barrel 4.
The course of work of the present invention is as follows: the first turnover oil nozzle 3, the second turnover oil nozzle 8, the 3rd turnover oil nozzle 11 join with hydraulic control device.When needs chuck 17 traveling priority, the 3rd turnover oil nozzle 11 is closed, and the first turnover oil nozzle 3 and the second turnover oil nozzle 8 are done the action of oil-feed or draining, can make first piston 22 drive piston rods 18 and chuck 17 is made traveling priority, clamping work pieces 16 or unclamp workpiece 16; While rotating as needs chuck 17, can close the first turnover oil nozzle 3, utilize the second turnover oil nozzle 8 and the 3rd turnover oil nozzle 11 to do the action of oil-feed or draining, the second piston 12 is moved, when the second piston moves, because helicoid 21 is stuck on the second pin 20, by the effect of the second pin 20 and helicoid 21, the second piston 12 is rotated, with because the first pin 9 is positioned on plane 7, the first pin 9 can make piston rod 18 rotate while rotating with the second piston 12 thereupon, finally makes chuck 17 rotate.The traveling priority of chuck 17 and the cooperation of rotation, can reach the purpose of avoiding corresponding component on clamp body, prevents that interference from occurring, and the fixture overall structure is simplified, and takes up room little, and flexible movements are reliable.
