Description
Technical field
The present invention relates to field of fixtures, be specifically related to a kind of tapping clamp.
Background technology
Tapping to be screwed in by screw tap in the bottom outlet that will bore with certain moment of torsion to process internal thread.At present along with the extensive use of Digit Control Machine Tool, raising manufacturing ability becomes the target that mechanical processing industry is pursued jointly.Numerically controlled lathe screw thread manufacture application is more and more extensive, but be difficult to control in tapping process, reduce cutting speed and reduce the amount of feeding, the propelling dynamics of such screw tap reduces, therefore its accuracy of thread produced is greatly reduced, increase the roughness of thread surface like this, tapped bore and accuracy of thread all have no way of controlling, and the problems such as burr are certainly more inevitable.But feeding rate is too fast, and the excessive screw tap that also easily causes of the moment of torsion caused fractures, thus affects machining accuracy, increases cutter loss, causes the increase of production cost.
Summary of the invention
Object of the present invention is at the tapping fixture providing a kind of machining accuracy high.
For achieving the above object, technical scheme of the present invention is as follows: a kind of tapping clamp, comprises screw tap and clamp body body, also comprises fixed muffle, and described clamp body body comprises gripping section and supporting section, and described gripping section is tubular and is connected with supporting section; Collet is provided with in described clamp body body gripping section, described screw tap is positioned at collet, described clamp body body gripping section overcoat has the locking nut of fixing screw tap and collet, described clamp body body overcoat has fixed muffle, the first spring is provided with between described clamp body body gripping section and fixed muffle, described clamp body body supporting section cover has the second spring, and supporting section is provided with the elastic force adjusting nut of screw thread and adjustable spring.
Operation principle of the present invention and beneficial effect as follows: clamp body body serves main effect in fixture.Clamp body body has the effect of clamping screw tap, can also play preventing screw tap when threaded screw thread and clamp body body relatively rotates, achieve the effect of transmitting torque.Fixed muffle part is fixed on lathe cutter saddle, and it is jockey body body part mainly.By the elastic force regulating elastic force adjusting nut to adjust the second spring, the elastic force of the second spring acts on fixed muffle, then fixed muffle makes fixed muffle and clamp body body produce relative sliding by the first spring action in gripping section again, screw tap is clamped and eliminates screw tap at the normal resistance using wearing and tearing rear incision workpiece to be subject to.Machining accuracy of the present invention is high, adjusts the resistance that workpiece is subject to, avoid screw tap to fracture in process by the first spring and the second spring.
Further, described screw comprises two, fixed muffle is connected more tight with clamp body body, firmly.
Further, be provided with pad between described second spring and elastic force adjusting nut, increase the contact area of the second spring and elastic force adjusting nut, be more convenient to elastic force adjusting nut and adjust the second spring force.
Further, described gripping section and supporting section are formed in one, and casting is convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of tapping fixture embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: fixed muffle 1, screw tap 2, elastic force adjusting nut 3, second spring 4, first spring 5, gripping section 6, locking nut 7, screw 8, collet 9, pad 10, supporting section 11.
Embodiment is substantially as shown in Figure 1: a kind of tapping clamp, comprises screw tap 2 and clamp body body, also comprise fixed muffle 1, and clamp body body comprises gripping section 6 and supporting section 11, and gripping section 6 and supporting section 11 are formed in one, and casting is convenient.Gripping section 6 is tubular and is connected with supporting section 11; Clamp body body gripping section 6 internal fixtion has collet 9, screw tap 2 is positioned at collet 9, clamp body body gripping section 6 overcoat has the locking nut 7 of fixing screw tap 2 and collet 9, clamp body body overcoat has fixed muffle 1, the first spring 5 is provided with between clamp body body gripping section 6 and fixed muffle 1, clamp body body supporting section 11 cover has the second spring 4, and supporting section 11 is provided with the elastic force adjusting nut 3 of screw thread and adjustable spring.Fixed muffle 1 and clamp body body be connected by screw 8 and screw 8 with fix 1 matched in clearance.Screw 8 comprises two, fixed muffle 1 is connected more tight with clamp body body, firmly.There is pad 10 between the second spring 4 and elastic force adjusting nut 3, increase the second spring 4 and the contact area of elastic force adjusting nut 3, be more convenient to elastic force adjusting nut 3 and adjust the second spring force.
By in concrete for collet 9 placing clamp body gripping section 6, locking nut 7 of screwing on, loads screw tap 2, tighten locking nut 7 again, utilize the inwall press-in collet 9 of lock nut, make it coordinate with the taper seat of gripping section 6, thus collet 9 tightens, screw tap 2 is fixed in collet 9.
When starting threaded screw thread, first screw tap 2 one thrusts will be given, make the stressed incision workpiece of screw tap 2, the size of this thrust is just decided by spring, and the size of spring force decides by the direction of rotation of elastic force adjusting nut 3, screw tap 2 blunt phenomenon is there will be after screw tap 2 uses a period of time, screw tap 2 is just difficult to incision workpiece, at this moment elastic force adjusting nut 3 can be twisted inwards, spring is compressed, elastic force is reacted on screw tap 2, increase the cutting-in force of screw tap 2.
Clamp body body serves main effect in fixture.Clamp body body has the effect of clamping screw tap 2, can also play preventing screw tap 2 when threaded screw thread and clamp body body relatively rotates, achieve the effect of transmitting torque.Fixed muffle 1 is fixed on lathe cutter saddle, and it is jockey body body mainly.By the elastic force regulating elastic force adjusting nut 3 to adjust the second spring 4, the elastic force of the second spring 4 acts on fixed muffle 1, then fixed muffle 1 acts on gripping section 6 by the first spring 5 again and makes fixed muffle 1 and clamp body body produce relative sliding, screw tap 2 is clamped and eliminates screw tap 2 to use the rear resistance cut workpiece and be subject to of wearing and tearing normal.Machining accuracy of the present invention is high, adjusts the resistance that workpiece is subject to, avoid screw tap to fracture in process by the first spring and the second spring.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
