Abstract
The utility model provides a welding point prying test tool which is a rod-shaped tool; the front end of the tool is a working end while the rear section thereof is a hand holding part; the working end gradually becomes flatter and flatter forwards; the flat working end is bent upwards relative to the rear section and forms an angle; the flat working end is provided with a clamping groove which is U-shaped, rectangular or V-shaped; and the width of the clamping groove is larger than the width of a welding point to be tested. The prying test tool uses the U-shaped clamping groove to clamp the welding point, pries parts upwards and can fully ensure prying test force when the plastic deformation of the parts is in place, thus ensuring the reliability of prying test results.
Description
Technical field
The utility model relates to a kind of to welded intensity quality inspection instrument, specifically, relates to a kind of solder joint sled inspection instrument.
Background technology
Body of a motor car generally is welded by about 5000 solder joints.The fastness of solder joint is most important to car load intensity.The control method of automobile Joint Strength has multiple, checks, can prize solder joint sled inspection etc. as the tear test of vehicle body solder joint, test piece.Wherein can prize the mode of solder joint sled inspection and use at most, be about to sled inspection chisel and directly insert between two solder joints and make part generation plastic yield, need only solder joint and do not throw off and judge that promptly solder joint is qualified.Referring to Fig. 1, common sled inspection is a rod tool, and the instrument front end is working end 1, and back segment 2 is a handgrip part, and working end 1 is for receiving flat flat gradually forward, and the working end of flat upwards bends with respect to back segment and is angle.By working end 1 is solid slug, when two solder joint points distances are big, is difficult to guarantee the close solder joint (about 3mm) of chisel, sees Fig. 2, thereby can not guarantee to prize inspection power that there is hidden danger in sled inspection result's reliability.
The utility model content
Technical problem to be solved in the utility model provides a kind of solder joint sled inspection instrument, with solve when weld spacing when distant, the problem of the poor reliability of measurement solder joint.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of solder joint sled inspection instrument, it is a rod tool, the instrument front end is the working end, back segment is a handgrip part, the working end is for receiving flat flat gradually forward, and the working end of flat upwards bends with respect to back segment and is angle, has the draw-in groove to open front on the working end of described flat.
Described draw-in groove is U-lag, rectangular channel or V-shaped groove, and the width of draw-in groove is greater than the width of the solder joint of need detection.
In the technical program, the design of fork-shaped draw-in groove has been adopted in the end of sled inspection instrument, has fully guaranteed solder joint sled inspection result's reliability, can guarantee weld strength better.
Description of drawings
Fig. 1 is the common sled inspection tool construction synoptic diagram before improving.
Fig. 2 is the common sled inspection instrument sled inspection solder joint synoptic diagram before improving.
Fig. 3 is the structural representation of a kind of solder joint sled inspection instrument of the present utility model.
Fig. 4 is a kind of solder joint sled inspection instrument sled inspection solder joint synoptic diagram of the present utility model.
Embodiment
As shown in Figure 3, the front end of solder joint sled inspection instrument of the present utility model is working end 1, back segment 2 is a handgrip part, working end 1 is for receiving flat flat gradually forward, the working end of flat upwards bends with respect to back segment and is angle, have the U-shaped draw-in groove 3 to open front on the working end of flat, draw-in groove thickness is generally 2-5mm, and the draw-in groove width is generally 10mm.
As shown in Figure 4, the using method of this sled inspection instrument is that the solder joint 5 of part 4 is stuck in the U-shaped draw-in groove 3 of sled inspection tool end, upwards prizes part, treats that the part plastic yield puts in place, can fully guarantee to prize inspection power, and solder joint sled inspection result's reliability is guaranteed.
Claims (3)
1, a kind of solder joint sled inspection instrument, it is a rod tool, the instrument front end is working end (1), back segment (2) is a handgrip part, working end (1) is for receiving flat flat gradually forward, the working end of flat upwards bends with respect to back segment and is angle, it is characterized in that, has the draw-in groove (3) to open front on the working end of described flat.
2, solder joint sled inspection instrument according to claim 1 is characterized in that described draw-in groove (3) is U-lag, rectangular channel or V-shaped groove.
3, solder joint sled inspection instrument according to claim 1 and 2 is characterized in that the width of described draw-in groove (3) is greater than the width of the solder joint of need detection.
