Description
Technical field
The utility model relates to a kind of mechanical device, is specifically related to a kind of screw cutting thread device.
Background technology
Screw is widely used in the every field such as machine-building, the screw thread of screw one end divides by tooth form angular thread, trapezoidal thread, square thread etc., wherein common metric system angular thread is most widely used, screw is in actual production process, need cutted thread and cylindrical, need to grip screw in turning process, because screw quality is comparatively hard, the active force needed for turning is larger.Clamping device of the prior art, because structural design is reasonable not, clamp stable not, turning screw thread rule degree is out poor, and precision is low, second-rate.
Therefore, on the basis of existing technology necessary, research and develop a kind of reasonable in design, easy to use, clamp reliable and stable, can prevent screw in turning process from rocking, the accuracy of thread processed is high, screw thread rule, the screw cutting thread device that quality is high.
Utility model content
Utility model object: the purpose of this utility model is to solve the deficiencies in the prior art, provides a kind of reasonable in design, easy to use, clamp reliable and stable, can prevent screw in turning process from rocking, the accuracy of thread processed is high, screw thread rule, the screw cutting thread device that quality is high.
Technical scheme: in order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of screw cutting thread device, it comprises lathe spindle, is arranged on the clamp body on lathe spindle, is arranged on the claw on clamp body right side, offers groove, be provided with spring in groove in described clamp body, and spring right-hand member is withstood by ejector pin; Be provided with tail stock on the right side of described claw, the left side of tail stock is provided with movable thimble;
Described ejector pin and claw movable contact;
Described claw and movable thimble intermediate vertical line are provided with lathe tool.
Preferably, above-described screw cutting thread device, described clamp body right side is provided with 3 to 4 claws.
As being more preferably scheme, above-described screw cutting thread device, described clamp body right side is provided with 3 claws.
Preferably, above-described screw cutting thread device, described claw is arranged on the right side of clamp body by bearing pin.
As being more preferably scheme, above-described screw cutting thread device, described claw offers the groove suitable with screw cylindrical.
The screw cutting thread device that the utility model provides, lathe spindle is arranged in lathe spindle internal taper hole, then screw excircle of workpiece end is loaded in the claw of clamp body, then shake into the movable thimble on tail stock, movable thimble is made to withstand screw workpiece right-hand member, make screw workpiece continue jacking left, screw excircle of workpiece end is advanced the claw front end of clamp body, thus the rear portion of claw is closed up gradually.When claw be brought together into collide with screw excircle of workpiece time, namely fix screw workpiece, last screw workpiece is by Automatic-clamping.Now can start lathe tool, carry out cutted thread to screw workpiece, after screw thread process, be return by movable thimble, claw by spring top out, takes off the screw of the good screw thread of turning and cylindrical.
Beneficial effect: compared to the prior art the screw cutting thread device that the utility model provides has the following advantages:
The screw cutting thread device that the utility model provides, reasonable in design, easy to operate, clamp reliable and stable, can prevent screw in turning process from rocking, the accuracy of thread processed is high, and screw thread rule, quality is high, practical.
Accompanying drawing explanation
The structural representation of the screw cutting thread device that Fig. 1 provides for the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
Embodiment 1
As shown in Figure 1, a kind of screw cutting thread device, it comprises lathe spindle (1), be arranged on the clamp body (2) on lathe spindle (1), be arranged on the claw (3) on clamp body (2) right side, offer groove in described clamp body (2), be provided with spring (4) in groove, spring (4) right-hand member is withstood by ejector pin (5); Described claw (3) right side is provided with tail stock (6), and the left side of tail stock (6) is provided with movable thimble (7);
Described ejector pin (5) and claw (3) movable contact;
Described claw (3) and movable thimble (7) intermediate vertical line are provided with lathe tool (8).
Above-described screw cutting thread device, described clamp body (2) right side is provided with 3 claws (3).
Above-described screw cutting thread device, described claw (3) is arranged on the right side of clamp body (2) by bearing pin (9).
Above-described screw cutting thread device, described claw (3) offers the groove suitable with screw cylindrical.
The screw cutting thread device that the utility model provides, lathe spindle (1) is arranged in lathe spindle internal taper hole, then the outer nose circle of screw workpiece (9) is loaded in the claw (3) of clamp body (2), then shake into the movable thimble (7) on tail stock (6), movable thimble (7) is made to withstand screw workpiece (9) right-hand member, screw workpiece (9) is made to continue jacking left, screw workpiece (9) outer nose circle is advanced the claw of clamp body (2) (3) front end, thus the rear portion of claw (3) is closed up gradually.When claw (3) be brought together into collide with screw workpiece (9) cylindrical time, namely fix screw workpiece (9), last screw workpiece (9) is by Automatic-clamping.Now can start lathe tool (8), carry out cutted thread to screw workpiece (9), after screw thread process, be return by movable thimble (7), claw (3) is ejected by spring (4), takes off the screw of the good screw thread of turning and cylindrical.
