Abstract
The invention relates to a self-locking floating clamp and belongs to a tool. The structure of the self-locking floating clamp includes that a support is in threaded connection with one end of a positioning shaft, the other end of the positioning shaft is provided with a three-piece elastic chuck structure, a left pressure plate is coaxially arranged on the outer circumference of the positioning shaft, and a right pressure plate is coaxially arranged on the outer circumference of the left pressure plate; the outer circumference of the end of the left pressure plate is provided with an outer thread, a locking nut is connected with the left pressure plate in a threaded manner, one end of the positioning shaft is sequentially provided with a conical hole and a threaded hole from outside to inside, the axis of the locking nut is provided with a cavity, a conical column and a threaded column are sequentially arranged at one end of a self-locking screw, the conical column is matched with the conical hole of the positioning shaft and the threaded column is matched with the threaded hole of the positioning shaft after the self-locking screw penetrates the cavity of the locking nut. The self-locking floating clamp of a three-piece tension type structure has the advantages of self-locking reliability, flexibility in operation and quickness and convenience in clamping and unclamping. Workpieces can be clamped on the positioning shafts in a floating manner and locked after work positions are determined according to working conditions, so that the self-locking floating clamp is particularly applicable to batch production.
Description
Technical field
The present invention relates to a kind of floating self-locking binding clasp, be applicable to the Quick-clamped frock of CNC milling machine and plain-milling machine.
Background technology
When current CNC milling machine and plain-milling machine milling workpiece, still want pressing plate clamping or tri-claw disk centering to clamp, this method clamping time is long, affects production efficiency, especially in the time producing in enormous quantities, trial assembly is pressed from both sides repeatedly, not only affect centering precision, reduce machining accuracy, but also affect production efficiency.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of floating self-locking binding clasp, this binding clasp adopts three lobe swelled structures, there is self-locking reliable, flexible operation, clamping, pine are pressed from both sides quick and convenient, the clamping workpiece that can float on locating shaft according to working condition, determines that operating position locks again, particularly suitable batch production.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of floating self-locking binding clasp, one end of locating shaft is threaded on bearing, the other end of locating shaft is provided with three lobe collet structures, excircle at locating shaft coaxially arranges left pressing plate, on locating shaft, be provided with rectangular groove, pin coordinates with rectangular groove through left pressing plate; Excircle at left pressing plate coaxially arranges right pressing plate, is provided with another rectangular groove at the excircle of left pressing plate, and holding screw withstands in the rectangular groove of left pressing plate through after right pressing plate, is provided with stop nut in the outer end of holding screw; In the end of left pressing plate, excircle is provided with external screw thread, and locking nut is threaded with left pressing plate; Outside the end of locating shaft has to interior taper hole and the screwed hole of being provided with successively, axle center at locking nut is provided with cavity, the end of self-locking screw rod is provided with tapered pole and threaded post successively, self-locking screw rod is through after the cavity of locking nut, tapered pole coordinates with locating shaft taper hole, and threaded post coordinates with the internal thread hole of locating shaft; On left pressing plate and right pressing plate, be respectively equipped with auricle corresponding to position, chuck is coaxially set on auricle.
This floating self-locking binding clasp adopts three lobe collets, and tapered pole by self-locking screw rod advances and retreat three lobe collet tensioners and unclamp, with ensure left pressing plate and right pressing plate when the work by tensioner, avoid workpiece to rotate and play; And by locking nut, left pressing plate and right pressing plate carrying out spacingly, screw and holding screw are the effects that prevents left and right pressing plate rotation simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation of floating self-locking binding clasp.
Detailed description of the invention
As shown in Figure 1, a kind of floating self-locking binding clasp, one end of locating shaft 7 is threaded on bearing 8, the other end of locating shaft 7 is provided with three lobe collet structures, excircle at locating shaft 7 coaxially arranges left pressing plate 5, is provided with rectangular groove on locating shaft 7, and pin 6 coordinates with rectangular groove through left pressing plate 5, not only ensure the left and right adjusting of left pressing plate, and prevented the rotation of left pressing plate 5; At the excircle of left pressing plate 5, right pressing plate 3 is coaxially set, be provided with another rectangular groove at the excircle of left pressing plate 5, holding screw 9 withstands in the rectangular groove of left pressing plate 5 through after right pressing plate 3, be provided with stop nut 10 in the outer end of holding screw 9, this locknut 2 can be fixed the relative position relation of left pressing plate 5 and right pressing plate 3; In the end of left pressing plate 5, excircle is provided with external screw thread, and locking nut 2 is threaded with left pressing plate 5, can the chuck on the pressing plate of left and right 4 be clamped part by the precession of locking nut 2; Outside the end of locating shaft 7 has to interior taper hole and the screwed hole of being provided with successively, axle center at locking nut 2 is provided with cavity, the end of self-locking screw rod 1 is provided with tapered pole and threaded post successively, self-locking screw rod 1 is through after the cavity of locking nut 2, tapered pole coordinates with locating shaft 7 taper holes, threaded post coordinates with the internal thread hole of locating shaft 7, after 1 precession of self-locking screw rod, can, by three lobe collet structure spreadings, play the object to left and right pressing plate self-locking; On left pressing plate 5 and right pressing plate 3, be respectively equipped with auricle corresponding to position, chuck 4 is coaxially set on auricle, be used for gripping part.
