Abstract
The utility model provides a fixture for machining an annular stud. The technical scheme includes that the fixture for machining the annular stud comprises a pressing plate, a double-thread screw, a nut, a pulling handle, a rotary plate, a taper pin, a spacer sleeve, a positioning plate, a positioning pin, a spring and a spring seat, a workpiece is arranged between the pressing plate and the rotary plate, the lower end of the double-thread screw is connected to the rotary plate through threads, the double-thread screw penetrates through the pressing plate, the upper end of the double-thread screw and the pressing plate are locked together through the nut, the rotary plate is arranged in an eccentric hole of the positioning plate, the center of the rotary plate deviates from the center of the positioning plate for L/2 when the center distance of the workpiece is L, the spacer sleeve is connected with the rotary plate through threads and is positioned through the taper pin, two symmetrical taper holes are formed in the rotary plate, the pulling handle is arranged at one end of the positioning pin, the other end of the positioning pin passes through the spring and the spring seat and stretches into the right taper hole of the rotary plate, the spring seat is connected with the positioning plate through threads, and the spring is pressed between the boss of the positioning pin and the spring seat. The fixture for machining the annular stud has the advantages that threads can be machined at the two ends of the workpiece simultaneously when the workpiece is clamped, efficiency is high, and quality is good.
Description
Technical field
The utility model relates to a kind of double end annular bolted fixture, belongs to the clamping tool for machine work technical field.
Background technology
During with commonsense method processing double end annular bolt, all be clamp first, one of centering, with this head thread car good and unclamp after, again clamping, centering and turning other end screw thread, this every clamping once can only car one head thread processing method, auxiliary time of production is many, efficient is low, clamping is frequent with the centering number of times, and it is tired that the processing personnel feel more, and crudy is difficult to guarantee.
Summary of the invention
The purpose of this utility model just provides a kind of double end annular bolted fixture, is used for addressing the above problem.
The technical solution of the utility model is: a kind of car double end annular bolted fixture, comprise pressing plate, double threaded screw, nut, handle, rotating disk, taper pin, interstage sleeve, positioning disk, alignment pin, spring and spring base, it is characterized in that: between pressing plate and the rotating disk workpiece is set, the double threaded screw lower end is coupled to rotating disk threadably, after passing pressing plate, the upper end is locked pressing plate by nut, be provided with rotating disk in the eccentric orfice of positioning disk, and the centre-to-centre spacing L that presses workpiece sets the center L/2 of the off-centring positioning disk of rotating disk, interstage sleeve and rotating disk link threadably, and by the taper pin location, rotating disk is provided with two symmetrical taper holes, and alignment pin one end is provided with handle, after the other end passes spring and spring base, stretch in the right taper hole on the rotating disk, spring base links with positioning disk threadably, and pressure mounting of the spring is between the boss and spring base of alignment pin.
The beneficial effects of the utility model are: but clamped one time car two head threads, efficient is high, and quality is good.
Description of drawings
Fig. 1 is the utility model master TV structure schematic diagram, and Fig. 2 is that the utility model is overlooked cross-sectional view.
The specific embodiment
With reference to accompanying drawing 1, Fig. 2 as can be known, a kind of car double end annular bolted fixture, comprise pressing plate 1, double threaded screw 2, nut 3, handle 4, rotating disk 5, taper pin 6, interstage sleeve 7, positioning disk 8, alignment pin 9, spring 10 and spring base 11, between pressing plate 1 and the rotating disk 5 workpiece 12 is set, double threaded screw 2 lower ends are coupled to rotating disk 5 threadably, after passing pressing plate 1, the upper end is locked pressing plate 1 by nut 3, be provided with rotating disk 5 in the eccentric orfice of positioning disk 8, and the centre-to-centre spacing L that presses workpiece 12 sets the center L/2 of the off-centring positioning disk 8 of rotating disk 5, interstage sleeve 7 links threadably with rotating disk 5, and by taper pin 6 location, rotating disk 5 is provided with two symmetrical taper holes, alignment pin 9 one ends are provided with handle 4, after the other end passes spring 10 and spring base 11, stretch in the right taper hole on the rotating disk 5, spring base 11 links with positioning disk 8 threadably, and spring 10 is fitted between the boss and spring base 11 of alignment pin 9.When using the utility model processing double end annular bolt, adopt 90 ° of lathe tools of the anti-sword of staight shank, elder generation's clamping and positioning dish 8 on engine lathe, and press positioning disk 8 external diameter centering machining centers, then workpiece 12 usefulness pressing plates 1 are pressed on and begin processing on the rotating disk 5, after processing threaded one end, the operator holds handle 4, extracts alignment pin 9, rotating disk 5 is rotated 180 °, after unclamping handle 4, under the tension force effect of spring 10, alignment pin 9 stretches in the left taper hole on the rotating disk 5, automatically with rotating disk 5 lockings, can process other end screw thread, whole process, 12 of workpiece need clamping once two head threads can be processed.
