Abstract
The utility model relates to a screw thread attaches a welding jig has solved conventional marking off method welding screw thread and has attached the seat and have up end plane degree, pitch -row precision, screw thread hole center line perpendicularity scheduling problem not up to standard. Including the locating pin, 2 guide pin bushing more than individual, bottom plate and fastening screw, the guide pin bushing is fixed on the bottom plate, the locating pin is through some slip posts of its upper band and the cooperation of guide pin bushing hole, the locating pin bottom have be used for connecting thread attach the seat the screw thread, it can be with the fastening screw of locating pin locking to install on the lateral wall of guide pin bushing, guide pin bushing pitch -row tolerance each other is less than welding back screw thread and attaches seat pitch -row tolerance each other, the plane degree of terminal surface is lighter than the plane degree requirement that needs the welded screw to attach the top face of seat under the plane degree of bottom plate and the guide pin bushing, the perpendicularity of guide pin bushing and bottom plate is less than welding back screw thread and attaches the seat for the planar perpendicularity of work piece, the interior aperture of guide pin bushing is lighter than the external diameter that the screw attaches the seat. The utility model discloses can show the welding quality that improves in groups the screw thread and attach the seat, raise the efficiency.
Description
Technical field
The utility model relates to fixture, particularly the attached seat weld jig of a kind of screw thread.
Background technology
The attached seat of multiple screw threads that product car body, gun turret weld, pitch-row General Requirements is L ± 0.5mm, and planarity requirements is for being not more than 1mm, and usually adopt hatched manner to determine to need the attached seat of screw thread of welding to put, hatched manner makes the error of dimension precision between the holes larger; Because the flatness of matrix exists error, be difficult to ensure welding rear attached seat upper surface flatness; Clamping instability in addition makes screwed hole central axis degree change in welding process, can not ensure perpendicularity requirement.To sum up, there is the problems such as upper surface flatness, dimension precision between the holes, screwed hole central axis degree be not up to standard in conventional method welding screw thread attached seat.
Summary of the invention
The utility model, by providing the weld jig of the attached seat of a kind of screw thread, solves conventional scribble method welding screw thread attached seat and there is the problems such as upper surface flatness, dimension precision between the holes, screwed hole central axis degree be not up to standard.
The utility model is realized by following technical scheme:
The weld jig of the attached seat of a kind of screw thread, comprise alignment pin, the guide pin bushing of more than 2, base plate and trip bolt, guide pin bushing is fixed on base plate, alignment pin by it with slide post and guide pin bushing inner hole, alignment pin bottom is with being used for the screw thread of the attached seat of connecting thread, the sidewall of guide pin bushing is provided with trip bolt alignment pin can locked, guide pin bushing pitch-row tolerance is each other less than the welding attached seat of rear thread pitch-row tolerance each other, the flatness of base plate and the flatness of guide pin bushing lower surface are less than the planarity requirements of the top end face of the attached seat of screw thread of needs welding, guide pin bushing and the perpendicularity of base plate are less than welds the perpendicularity of the attached seat of rear thread relative to workpiece planarization, the internal orifice dimension of guide pin bushing is less than the external diameter of the attached seat of screw thread.
Be hollow-core construction in the middle of base plate.
Adopt the attached seat welding mechanism of this screw thread, the welding quality of the attached seat of screw thread in groups can be significantly improved, raise the efficiency simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the left view of Fig. 2.
Detailed description of the invention
As Figure 1-3, the utility model is the weld jig of the attached seat of a kind of screw thread, comprise alignment pin 1, plural guide pin bushing 2, base plate 4 and trip bolt 5, guide pin bushing 2 is fixed on base plate 4, alignment pin 1 by it with slide post and guide pin bushing 2 inner hole, alignment pin 1 bottom is with being used for the screw thread of the attached seat 3 of connecting thread, the sidewall of guide pin bushing 2 is provided with the trip bolt 5 alignment pin 1 can locked, guide pin bushing 2 pitch-row tolerance is each other less than the welding attached seat 3 of rear thread pitch-row tolerance each other, the flatness of base plate 4 and the flatness of guide pin bushing 2 lower surface are less than the planarity requirements of the top end face of the attached seat 3 of screw thread of needs welding, guide pin bushing 2 and the perpendicularity of base plate 4 are less than welds the perpendicularity of the attached seat 3 of rear thread relative to workpiece planarization, the internal orifice dimension of guide pin bushing 2 is less than the external diameter of the attached seat of screw thread.Handled easily can be emptied in the middle of in the middle of base plate 4.
The relevant attached seat 3 of one group of screw thread is arranged on weld jig by base plate 4 simultaneously, is reference measurement screw thread attached seat 3 end face plane degree with base plate 4, if do not met design requirement, by processing guide pin bushing 2 bottom thus the flatness of the attached seat 3 of screw thread in upper surface of guarantee welding.Base plate 4 can ensure the dimension precision between the holes of the attached seat 3 of the screw thread of same bond pads simultaneously.
During use, soldered attached seat is screwed on alignment pin, by the suitable rear trip bolt locking positioning pin of the flatness of attached for screw thread seat adjustment.The weld jig of attached for screw thread seat being placed on workpiece needs the position of welding to carry out welding, and some postwelding, unclamps trip bolt, screw out alignment pin, then this mechanism removed.Can additional positioning mechanism (as locating detent, alignment pin) during use, the screw thread connected with attached seat is twisted 3-5 and is detained.Weld jig is pulled down after having welded.
The beneficial effects of the utility model are as follows:
1, ensure that the upper surface often organizing the attached seat of screw thread is in the same plane.
2, the pitch-row of screwed hole is ensured.
3, the perpendicularity requirement of the attached seat axis of screw thread and welding work pieces is ensured.
Claims (2)
1. the attached seat weld jig of screw thread, it is characterized in that: comprise alignment pin, the guide pin bushing of more than 2, base plate and trip bolt, guide pin bushing is fixed on base plate, alignment pin by it with slide post and guide pin bushing inner hole, alignment pin bottom is with being used for the screw thread of the attached seat of connecting thread, the sidewall of guide pin bushing is provided with trip bolt alignment pin can locked, guide pin bushing pitch-row tolerance is each other less than the welding attached seat of rear thread pitch-row tolerance each other, the flatness of base plate and the flatness of guide pin bushing lower surface are less than the planarity requirements of the top end face of the attached seat of screw thread of needs welding, guide pin bushing and the perpendicularity of base plate are less than welds the perpendicularity of the attached seat of rear thread relative to workpiece planarization, the internal orifice dimension of guide pin bushing is less than the external diameter of the attached seat of screw thread.
