Technical Field
The utility model relates to a double-screw bolt location technical field especially relates to a positioner is used in double-screw bolt production.
Background
The stud refers to a fastener which has no head part and only has external threads at two ends, such as a double-end stud, a welding stud and the like. In connection (sometimes called a screw), one end of it must be screwed into a part with an internally threaded hole, the other end of it passes through a part with a through hole, and then a nut is screwed on, even if the two parts are fastened to be connected into a whole. This type of connection is called a stud connection and also belongs to the field of detachable connections.
The range of application of the double-end stud is wider, but the double-end stud needs to be processed at two ends in a processing process in a grading manner, and the double-end stud can be clamped and positioned once again in the processing process, so that the thread difference at two ends of the double-end stud is too obvious.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving and having stud among the prior art and need carry out both ends processing in the course of working in grades, stud can press from both sides tightly once again and fix a position in the in-process of processing to let the too obvious shortcoming of screw thread difference at stud both ends, and the double-screw bolt production that proposes uses positioner.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a positioner is used in double-screw bolt production, includes the double-screw bolt, be provided with the connecting seat on the double-screw bolt, the both sides of connecting seat all are provided with press from both sides tight seat, two press from both sides the relative outside of tight seat and all install the connecting rod through the bearing, two all set up flutedly on the connecting rod, two all be provided with the carriage release lever in the recess, two be provided with the shell between the carriage release lever, double-screw bolt one end is located in the shell, the shell is kept away from double-screw bolt one end is installed the location axle, two the connecting rod with be provided with canceling release mechanical system between the shell, the double-screw bolt with be provided with stop gear between the shell.
Preferably, the reset mechanism comprises two connecting blocks, and springs are arranged between the two connecting blocks and the shell.
Preferably, the limiting mechanism comprises two fixing pins which are in threaded connection with the shell, and one ends of the two fixing pins are extruded on the stud.
Preferably, the two grooves and the two moving rods are in transition fit.
Preferably, the two clamping seats are provided with anti-skid grains at one side close to the stud.
The utility model provides a pair of positioner is used in double-screw bolt production, beneficial effect lies in: this positioner is used in double-screw bolt production need be because two clamp seats are connected with two connecting rods through the bearing, use the double-screw bolt to take two clamp seats and can be at two connecting rod internal rotations, then at the rotation double-screw bolt, then the double-screw bolt has formed good thread end and is close to the shell, loosen the double-screw bolt, the spring can let the double-screw bolt have screw thread one end and get into in the shell, then press from both sides tightly the double-screw bolt through two fixed pins, then let the other end of double-screw bolt carry out the car screw thread on the lathe, thereby let the difference between the screw thread at double-screw bolt both ends reduce.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Example 1
Referring to fig. 1-4, a positioner is used in double-screw bolt production, including double-screw bolt 1, be provided with connecting seat 2 on the double-screw bolt 1, the both sides of connecting seat 2 all are provided with press from both sides tight seat 3, two press from both sides the relative outside of tight seat 3 and all install connecting rod 4 through the bearing, all set up fluted 5 on two connecting rods 4, all be provided with carriage release lever 6 in two recesses 5, be provided with shell 7 between two carriage release levers 6, double-screw bolt 1 one end is located shell 7, shell 7 is kept away from 1 one end fixed mounting of double-screw bolt and is had location axle 8, be provided with canceling release mechanical system between two connecting rods 4 and the shell 7, be provided with stop gear between double-screw bolt 1 and the shell 7, stop gear includes fixed mounting at two connecting blocks 9, all be provided with spring 10 between two connecting blocks 9 and the shell 7, stop gear includes two fixed pins 11 of threaded connection on shell 7, two fixed pin 11 one end all extrude on double-screw bolt 1.
The clamping seats 3 are all hydraulic clamping seats, and the stud 1 is clamped through a hydraulic expansion method.
Clamping a positioning shaft 8 on a triangular chuck on a machine tool, clamping a stud 1 in two clamping seats 3, positioning one end of the stud 1 in a shell 7, clamping the stud 1 through the fixing pins 11 by rotating the two fixing pins 11 (and calibrating through a dial indicator), threading one end of the stud 1 on the machine tool, when threading the other end of the stud 1 is needed, rotating the two fixing pins 11 to enable the stud 1 to move in the shell 7, pulling the stud 1 to enable two springs 10 to bear force, (because the two clamping seats 3 are connected with two connecting rods 4 through bearings, the two clamping seats 3 can rotate in the two connecting rods 4 by using the stud 1), then rotating the stud 1, enabling the formed threaded end of the stud 1 to be close to the shell 7, loosening the stud 1, enabling the spring 10 to enable the threaded end of the stud 1 to enter the shell 7, clamping the stud 1 through the two fixing pins 11 (and calibrating through the dial indicator), and threading the other end of the stud 1 on the machine tool, thereby reducing the difference between the threads of the two ends of the stud 1.
