Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The invention will be described in further detail with reference to the following drawings and embodiments:
referring to fig. 1, the embodiment of the utility model provides a positioning jig, including base 1 and flywheel dish 2, the center of base 1 is provided with round hole 10, flywheel dish 2 sets up on base 1, and flywheel dish 2 uses the central axis of round hole 10 to set up as the central line, be provided with a plurality of clamping jaws 3 on the flywheel dish 2, a plurality of clamping jaws 3 evenly arrange along the circumference direction of flywheel dish 2, clamping jaw 3 includes axle center end 30 and location end 31, location end 31 can be around axle center end 30 rotation, and the central axis of the relative axle center end 30 pivoted orbit of location end 31 process round hole 10.
The utility model discloses positioning jig for carry out welding process's in-process at the closing cap machine to tube socket and pipe cap, realize the location to the tube socket, with the concentricity with the pipe cap that improves the tube socket. The tube socket is installed in the round hole 10 of base 1, the location end 31 of a plurality of clamping jaws 3 all rotates towards the direction of the central axis that is close to round hole 10 when locating the tube socket, thereby press from both sides tight tube socket in the different positions department of the side of tube socket respectively, when the concentricity error of tube socket is great, the tube socket receives the size of the effort of the location end 31 of a plurality of clamping jaws 3 and differs, thereby make the position of tube socket obtain the adjustment, when the tube socket reaches sufficient concentricity, the resultant force of the effort of a plurality of clamping jaws 3 to the tube socket is close to zero for the location end 31 of a plurality of clamping jaws 3.
According to the utility model discloses an embodiment, the quantity of clamping jaw 3 is three, and three clamping jaw 3 is in the circumferential direction of flywheel dish 2, and the central angle between two adjacent clamping jaws 3 is 120 degrees.
According to the utility model discloses an embodiment, flywheel dish 2 rotationally sets up on base 1, and flywheel dish 2 uses the central axis of round hole 10 as the rotation center line. The utility model discloses realizing the location to the tube socket, mainly being the position that the tube socket was adjusted to the effort of tube socket through the location end 31 of a plurality of clamping jaws 3, realizing the regulation to the tube socket concentricity, based on this, this embodiment drives clamping jaw 3 through the rotation of flywheel dish 2 and rotates, when flywheel dish 2 rotates promptly, clamping jaw 3 on the flywheel dish 2 is driven and takes place to rotate, and realizes the regulation to the concentricity of tube socket. Because the quantity of clamping jaw 3 is many, directly drives clamping jaw 3, and synchronism and accuracy are difficult to guarantee, and drive a plurality of clamping jaws 3 through flywheel dish 2 and rotate, because a plurality of clamping jaws 3 all set up on flywheel dish 2, consequently can guarantee the synchronism and the accuracy of a plurality of clamping jaws 3 when the motion more conveniently.
In a specific example, the surface of the base 1 is provided with a shoulder 11, the flywheel disk 2 is sleeved on the shoulder 11, and the bottom surface of the flywheel disk 2 is arranged on the surface of the base 1. It will be appreciated that the shoulder 11 is of circular configuration, which acts as the axis of rotation of the flywheel disc 2.
According to the utility model discloses an embodiment, on clamping jaw 3, axle center end 30 is provided with first fixed screw 4, and on first fixed screw 4 passed flywheel dish 2 and was fixed in base 1, still be provided with second fixed screw 5 between axle center end 30 and the location end 31, be provided with first circular arc groove 32 on the clamping jaw 3, second fixed screw 5 passed first circular arc groove 32 and fixes on flywheel dish 2. As shown in fig. 1, the first arc groove 32 is provided along the length direction of the holding jaw 3. When the flywheel disc 2 rotates, at the axle center end 30, because the first fixing screw 4 is fixed on the base 1, the axle center end 30 is kept still under the action of the first fixing screw 4, and within the range of the first arc groove 32, because the second fixing screw 5 is fixed on the flywheel disc 2, the second fixing screw 5 rotates along with the rotation of the flywheel disc 2, and, when the second fixing screw 5 rotates, because the axle center end 30 does not rotate, under the action of the second fixing screw 5, the clamping jaw 3 is driven to rotate, and the second fixing screw 5 moves in the first arc groove 32. In addition, when flywheel dish 2 rotates, a plurality of clamping jaws 3 rotate under the effect of first fixed screw 4, second fixed screw 5 and first circular arc groove 32, and the emergence is rotated simultaneously, and the pivoted direction is unanimous, and then realizes the location to the tube socket.
Further, a second arc groove 20 is further formed in the flywheel disc 2, and the first fixing screw 4 is arranged in the second arc groove 20. As shown in fig. 1, the center of curvature of the second circular arc groove 20 is located on the central axis of the circular hole 10. The second arc groove 20 is used for buffering a period of time before the clamping jaw 3 moves, when the first fixing screw 4 abuts against the end of the second arc groove 20, if the rotation direction of the flywheel disc 2 enables the abutting force of the end of the first fixing screw 4 and the end of the second arc groove 20 to be increased, the clamping jaw 3 is rotated by further rotating the flywheel disc 2, and if the rotation of the flywheel disc 2 enables the abutting force of the end of the first fixing screw 4 and the end of the first arc groove 20 to be reduced, or the first fixing screw 4 is located in the middle section of the second arc groove 20, the clamping jaw 3 does not rotate together with the rotation of the flywheel disc 2 before the flywheel disc 2 rotates to a certain angle.
In the embodiment of the present invention, in order to ensure the smooth movement of the clamping jaw 3, the first fixing screw 4 and the second fixing screw 5 are respectively movably connected to the surface of the flywheel panel 2. In this embodiment, the first fixing screw 4 and the second fixing screw 5 are used as fixing parts for the rotation of the clamping jaw 3, on one hand, it is required to ensure that the clamping jaw 3 does not move in the vertical direction after being installed on the flywheel disc 2, on the other hand, the first fixing screw 4 and the second fixing screw 5 cannot apply an excessive pre-tightening force to the clamping jaw 3, otherwise, the clamping jaw 3 cannot rotate relative to the flywheel disc 2, optionally, by disposing a gasket between the first fixing screw 4 and the second fixing screw 5 and the surface of the flywheel disc 2, the precision of the surface of the gasket is improved by processing, and at the same time, the surface of the flywheel disc 2 is processed, such as polished, to ensure that the surface of the flywheel disc 2 has sufficient smoothness, thereby ensuring that under the condition that the first fixing screw 4 and the second fixing screw 5 apply a pre-tightening force to the flywheel disc 2 enough to prevent the movement of the flywheel disc 2, the flywheel disc 2 can rotate relative to the first fixing screw 4 and the second fixing screw 5.
