SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a quick clamping frock of annular packing ring, once only realize the quick location of thin wall part through the frock and press from both sides tightly, change the clamping mode of current inefficiency, low yield, improve production efficiency and processingquality.
Realize the utility model discloses the technical solution of purpose does: a quick clamping tool for an annular gasket comprises a core rod, a sleeve, a clamping jaw and a lock nut;
the upper end of the core rod is provided with a flanging convex edge, the middle part of the inner wall of the sleeve is provided with an annular boss, the sleeve is sleeved on the periphery of the core rod, the flanging convex edge of the core rod is positioned on the upper part of the annular boss of the sleeve, and the flanging convex edge is connected with the annular boss;
a plurality of jaw mounting grooves are uniformly distributed in the circumferential direction of the sleeve, the middle of each jaw is rotatably connected with the side wall of the sleeve, and the side surface of the upper end of each jaw is in contact with the side surface of the flange convex edge and is used for clamping the annular gasket;
the periphery of the core rod is in threaded connection with a lock nut, an annular groove is formed in the middle of the lock nut, one side, close to the core rod, of the annular groove is an inclined plane, when the lock nut is rotated, the clamping claw rotates under the action of the inclined plane of the lock nut, and the annular gasket is clamped.
Furthermore, the clamping jaws are rotatably connected with the sleeve through cylindrical pins.
Further, the number of the clamping jaws is four.
Furthermore, the included angle between the inclined plane in the annular groove of the lock nut and the vertical direction is 5-30 degrees.
Furthermore, the flange convex edge is connected with the annular boss through a plurality of countersunk head screws.
Further, the core rod is provided with external threads, the lock nut is provided with internal threads, and the core rod and the lock nut are in threaded connection through the external threads and the internal threads
Compared with the prior art, the utility model, it is showing the advantage and lies in:
the tool realizes quick positioning of the gasket through the sleeve and the core rod, and quick clamping of the gasket is realized through the locking nut and the clamping jaw, so that the mode of a dealer of the conventional common three-jaw chuck is changed, and the production efficiency and the processing quality are improved.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-5, a rapid clamping tool for an annular gasket is formed by assembling four parts, namely a core bar 1, a sleeve 2, a jaw 3 and a lock nut 4, according to a six-point positioning principle by adopting a design scheme of combined installation, wherein a cylindrical surface at the front end of the core bar 1 is matched with a sunken frame of the annular gasket, the gasket is supported inside during clamping, the sleeve 2 is assembled on the core bar 1, the end surface of the sleeve 2 is attached to a flange of the gasket to realize rapid positioning of the gasket, the jaw 3 is fixed on the sleeve through a cylindrical pin 5, the lock nut 4 is connected with the core bar 1 through threaded fit, the lock nut 4 is rotated, the jaw 3 is driven by an inner wedge surface of the lock nut 4 to realize lever movement, so that the jaw 3 compresses the gasket, and locking and clamping of the gasket are realized.
The clamping tool comprises the following working processes:
step 1, a clamping jaw 3 is arranged on a sleeve 2 through a cylindrical pin 5 and fastened;
step 2, penetrating the sleeve 2 into the core rod 1, flatly pasting a middle boss surface of the sleeve 2 with the rear end surface of the flanging of the core rod 1, and screwing in a countersunk screw 6 to fasten the core rod 1 and the sleeve 2;
step 3, mounting the annular gasket into the tool from the left side, wherein the inner cylindrical surface of the gasket is tightly attached to the outer circle of the flanging of the core rod 1, and the rear end surface of the flanging of the gasket is attached to the front end surface of the sleeve 2, so that the positioning of the gasket is realized;
step 4, screwing the lock nut 4, and driving the clamping jaw 3 to tightly press the side wall of the gasket by the wedge-shaped inclined plane on the lock nut 4 to clamp the gasket;
step 5, processing the gasket;
and 6, loosening the locking nut 4, and taking down the gasket to finish machining.
