Abstract
A thread processing chuck consists of a conical handle and a tapping plate, wherein a cylindrical hole is fixedly on one end of the conical handle along the axial direction; a sliding sleeve in a cylindrical pipe shape is arranged in the cylindrical hole; the outer diameter of the sliding sleeve is matched with the inner diameter of the cylindrical hole; a radial screw hole is arranged on the pipe wall of the sliding sleeve; a chute is arranged between the inner and the outer walls of the cylindrical hole in a direction parallel to the axial direction; a bolt is arranged on the conical handle and is connected with the radial screw hole through the chute at the front end; and the tapping plate is coaxially arranged in the outer end of the sliding sleeve and is fixedly connected with the outer end of the sliding sleeve through a radial fastening screw penetrating through the outer circumferential wall of the sliding wall. By combining the tapping plate and the sliding sleeve, the thread processing chuck can achieve thread processing through a lathe. Meanwhile, the separable design of the tapping plate and the sliding sleeve can conveniently change the tapping plate to achieve serial processing of threads, and the thread processing chuck has good generality and convenient usage.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to frock clamp, particularly a kind of screw thread processing chuck.
Background technology:
When on lathe, utilizing the direct turning spindle nose of lathe tool screw thread, be the assurance accuracy of thread, in the prior art, must grind accurate cutting-tool angle, adorn positive cutter, and strict by the pitch choosing to transmission change gear and control cutting depth, so process complexity, and be not easy to guarantee thread quality; And adopting special tooling to process, special tooling makes trouble, versatility is not strong, operation inconvenience.
Summary of the invention:
The purpose of this utility model provides a kind of screw thread processing chuck, and described this screw thread processing chuck will solve and utilize the technical problem that machining screw complicated operation, thread quality are difficult to guarantee on the lathe in the prior art.
This screw thread processing chuck of the present utility model is made of taper shank and filament plate, wherein, one end of described taper shank is set with a cylindrical hole vertically, be provided with a sliding sleeve in the described cylindrical hole, described sliding sleeve is cylindrical tube, the external diameter of described sliding sleeve matches with the internal diameter of cylindrical hole, the tube wall of sliding sleeve is provided with radially screw, be parallel between the inside and outside wall of cylindrical hole and axially be provided with a chute, taper shank is provided with a bolt, its front end was connected with described radially screw after described bolt passed described chute, described filament plate is coaxial to be arranged in the outer end of sliding sleeve, filament plate by passing sliding sleeve outer end circumferential wall radially holding screw and the outer end of sliding sleeve be connected and fixed.
Further, the outer end of described sliding sleeve is provided with step, and the external diameter of described stage portion is greater than the external diameter of cylindrical hole, and the external diameter of filament plate and the internal diameter of stage portion match and merge internal diameter greater than sliding sleeve.
Operation principle of the present utility model is: earlier by major diameter of thread with workpiece turning to requirement size and chamfering, again taper shank is connected on the lathe, reduce the speed of mainshaft, on workpiece and filament plate surface, be coated with a little lubricating oil, shake the feeding of tailstock handle filament plate is entangled workpiece, sliding sleeve moves forward automatically during the cover tapping, withdraws from automatically during the lathe backward rotation.Can change filament plate easily by holding screw, also can change sliding sleeve, can be convenient for changing individual part like this and can realize that screw thread series dimensioned is general by bolt.Taper shank can directly be used with useless thimble taper shank transformation of the way cost frock.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model combines filament plate and shift sleeve structure, by the processing of lathe realization screw thread, simultaneously, with filament plate and sliding sleeve split design, can change the seriation processing that filament plate is realized screw thread easily, and versatility is good, and is easy to use.
Description of drawings:
Fig. 1 is the structural representation of screw thread processing chuck of the present utility model.
The specific embodiment:
As shown in Figure 1, screw thread processing chuck of the present utility model is made of taper shank 1 and filament plate 3, wherein, one end of described taper shank 1 is set with a cylindrical hole vertically, be provided with a sliding sleeve 2 in the described cylindrical hole, described sliding sleeve 2 is cylindrical tube, the external diameter of described sliding sleeve 2 matches with the internal diameter of cylindrical hole, the tube wall of sliding sleeve 2 is provided with radially screw, be parallel between the inside and outside wall of cylindrical hole and axially be provided with a chute 7, taper shank 1 is provided with a bolt 4, described bolt 4 passes described chute 7 its front ends of back and is connected with described radially screw, described filament plate 3 is coaxial to be arranged in the outer end of sliding sleeve 2, and the radially holding screw 5 of filament plate 3 by passing sliding sleeve 2 outer end circumferential wall is connected and fixed with the outer end of sliding sleeve 2.
Further, the outer end of described sliding sleeve 2 is provided with step, and the external diameter of described stage portion is greater than the external diameter of cylindrical hole, and the external diameter of filament plate 3 and the internal diameter of stage portion match and merge internal diameter greater than sliding sleeve 2.
The course of work of present embodiment is: earlier by major diameter of thread with workpiece 6 turning to requirement size and chamfering, again taper shank 1 is connected on the lathe, reduce the speed of mainshaft, on workpiece 6 and filament plate 3 surfaces, be coated with a little lubricating oil, shake the feeding of tailstock handle filament plate 3 is entangled workpiece 6, sliding sleeve 2 moves forward automatically during the cover tapping, withdraws from automatically during the lathe backward rotation.Can change filament plate 3 easily by holding screw 5, also can change sliding sleeve 2, can be convenient for changing individual part like this and can realize that screw thread series dimensioned is general by bolt 4.Taper shank 1 can directly be used with useless thimble taper shank 1 transformation of the way cost frock.
