Abstract

A telescopic tapping clamp for a machine comprises a main handle sleeve and a tap chuck, and is characterized in that a slide opening is formed at the rear end of the main handle sleeve, a fixed core shaft is arranged at the front end of the tap chuck, a synchronously rotating clamping groove is formed at the rear end of the tap chuck, and the fixed core shaft and the slide opening are in sliding fit with each other in the axial direction and are matched with each other in a circumferentially positioning manner. In the utility model, since the tap chuck which is in sliding fit with the main handle sleeve in axial direction and is matched with the main handle sleeve in a circumferentially positioning manner is arranged on the main handle sleeve, the axial sliding of the tap chuck can compensate the difference between the axial motion of drive equipment and actual pitch motion when the telescopic tapping clamp for the machine, provided by the utility model, is used for carrying out tapping work. The quality of tapping work is improved remarkably. Moreover, the utility model further has the advantages as follows: during the use, the mounting and centering of the tap are accurate, the stretching and compensating are free, the clamping is firm, and safety and reliability are achieved.

Description

Machine is with flexible tapping clamp
Technical field
The utility model relates to the clamping device of a kind of tapping with screw tap, and specifically a kind of machine is with flexible tapping clamp.
Background technology
At present; Between screw tap in the threading apparatus and the chuck axially for being rigidly connected, when threading apparatus is worked, the screw tap cutting movement that under the drive of driving arrangement, rotates; This moment, screw tap was controlled by driving arrangement in axial motion; Yet driving arrangement there are differences in the motion that axial motion and actual pitch move sometimes, and this species diversity can obviously influence the quality of tapping.The quality problems of screw thread in the product can be brought serious potential safety hazard to the equipment of this screw thread of subsequent applications.
Summary of the invention
The purpose of the utility model is to provide a kind of machine that can significantly improve the tapping quality with flexible tapping clamp to above-mentioned deficiency.
The utility model is achieved in that and comprises main sleeve and tap chuck; It is characterized in that: the rear end of said main sleeve offers slide opening; The front end of said tap chuck is provided with centering spindle; The rear end of said tap chuck is provided with synchronous rotation draw-in groove, axial sliding fit between said centering spindle and the slide opening, and circumferentially the location cooperates.
Said slide opening is inboard is axially arranged with first keyway, the said centering spindle outside be axially arranged with second keyway, be fixed with flat key on said second keyway, said second keyway cooperates with first keyway through flat key.
The said centering spindle outside stopper slot axially is set, said main sleeve is provided with the stop screw that cooperates with stopper slot.
Said tap chuck is provided with the jackscrew that the shank to screw tap positions.
Said synchronous rotation draw-in groove is made up of circular hole and draw-in groove hole that coaxial communication is provided with, and wherein, said circular hole places the rear end of tap chuck, and the draw-in groove hole connects the upper end of circular hole.
The utility model through on main sleeve, be provided with can with its axial sliding fit; And circumferentially locate the tap chuck that cooperates; Make when operating personnel use the utility model to carry out the tapping operation that the endwisely slipping of tap chuck can compensate the difference that motion that driving arrangement moves in axial motion and actual pitch exists.Significantly improved the quality of tapping operation.And, the utility model also have use plug tap install centering accurately, flexible compensation freely, firm, the safe and reliable advantage of clamping.

The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Embodiment: as shown in Figure 1, comprise main sleeve 1 (Mohs taper master sleeve) and tap chuck 2, the rear end of main sleeve 1 offers slide opening 3; The front end of tap chuck 2 is provided with centering spindle 4; The rear end of tap chuck 2 is provided with synchronous rotation draw-in groove 5, axial sliding fit between centering spindle 4 and the slide opening 3, and circumferentially the location cooperates; Centering spindle 4 outsides stopper slot 8 axially is set; Main sleeve 1 is provided with the stop screw 9 that cooperates with stopper slot 8, and tap chuck 2 is provided with the jackscrew 10 that the shank to screw tap 14 positions, and promptly becomes the utility model.Stop screw 9 is used for limiting the axial displacement degree of tap chuck 2 at main sleeve 1, prevents that tap chuck 2 breaks away from.
In the technique scheme, slide opening 3 is inboard is axially arranged with first keyway 15, and being axially arranged with of centering spindle 4 outsides is fixed with flat key 7, the second keyways 6 and cooperates with first keyway 15 through flat key 7 on second keyway, 6, the second keyways 6.
In the technique scheme, as shown in Figure 2, rotate draw-in groove 5 synchronously and form with draw-in groove hole 12 by the circular hole 11 that coaxial communication is provided with, wherein, circular hole 11 places the rear end of tap chuck 2, and draw-in groove hole 12 connects the upper end of circular hole 11.The draw-in groove hole is used for tap chuck 2 and transmits moment of torsion to screw tap 14.The position of jackscrew 10 is corresponding with draw-in groove hole 12, and arbitrary corresponding surface that screw tap 14 shanks are square bores groove, and after screw tap 14 was packed synchronous rotation draw-in groove 5 into, jackscrew 10 withstood the groove of screw tap 14, prevents that screw tap 14 breaks away from.
When the utility model used, the front end of main sleeve 1 was assembled on the machine tool chief axis, and the shank of screw tap 14 is assembled in the synchronous rotation draw-in groove 5; And withstand screw tap 14 with jackscrew 10; Lathe passes to tap chuck 2 through main sleeve 1 with moment of torsion, rotates the tapping operations thereby drive screw tap 14, when the axial move distance that provides when the pitch displacement and the lathe of reality there are differences; Tap chuck 2 can move axially in main sleeve 1; Compensate above-mentioned difference, improve the quality of tapping operation, guarantee the reliability of the screw thread that tapping forms.
