Abstract
The utility model discloses a simple manual tearing platform suitable to test the strength of a resistance spot welding sample, which comprises a worktable, a clamping mechanism and a rocker assembly. The rocker assembly comprises a tearing rocker and a rocker supporting seat. The rocker supporting seat is fixed on the worktable. The tearing rocker is arranged on the rocker supporting seat. The top end of the tearing rocker is provided with a clamping seam for clamping a tearing sample. The clamping mechanism comprises a threaded sleeve, a supporting seat, a screw rod, a clamping rocker and a pedestal. The supporting seat is arranged on the pedestal, the threaded sleeve is welded on the supporting seat, the screw rod is arranged on the supporting seat by the threaded sleeve, the clamping rocker is arranged on the screw rod, and the lower end surface of the screw rod is opposite to the pedestal so as to clamp the sample. One end of the sample is clamped in the clamping mechanism, while the other end thereof is clamped in the clamping seam of the tearing rocker, and then the resistance spot welding sample can be torn along the welding spot edge by rotating the rocker. The utility model has the advantages of simple structure, small occupied space and simple and convenient use.
Description
Technical field
The utility model belongs to the resistance spot welding sample and tears the experiment detection architecture.
Background technology
For the detection of resistance spot welding welding quality, also lack reliable lossless detection method at present, welding quality can only lean on the destructive test of technology sample and workpiece to check.Detecting at the destructive test of technology sample and workpiece, mainly is that the size and the standard value of the nugget diameter by measuring part compares.Traditional technology sample destructive test is to stretch by universal testing machine to tear, and measures the nugget diameter after tearing then.Prior art utilizes universal testing machine to carry out spot-welding sample stretching tear test, and operating efficiency is lower, and costs an arm and a leg.Particularly for automobile manufacture industry, the spot-welding technology sample in new car exploitation trial production and volume production process control is more, and needs to detect with line fast and judge that traditional testing machine stretches to tear more and more and can not satisfy this requirement.
Summary of the invention
The purpose of this utility model is the deficiency at existing testing equipment existence, propose a kind ofly to be applicable to that the manual simplified experiment of resistance spot welding sample intensity detection tears platform, guaranteeing under the identical experimental result prerequisite, reducing experimentation cost and raising with the thread test detection efficiency.
The technical solution of the utility model is as follows:
A kind of manual simplified platform of tearing that is applicable to resistance spot welding sample intensity detection, the described simple and easy platform of tearing comprises worktable, clamp system and rocker assembly; Described clamp system and rocker assembly are fixed on the worktable by certain relative position.
Described rocker assembly comprises tears rocking bar and rocking bar supporting seat, the rocking bar supporting seat is fixed on the worktable, tear rocking bar and be installed on the rocking bar supporting seat, the top of tearing rocking bar has one to clamp the card seam of tearing sample, and the position of card seam is relative with the position of clamp system.
Described clamp system comprises swivel nut, supporting seat, screw rod, clamping rocking bar, base; Described supporting seat is installed on the base, and swivel nut is welded on the supporting seat, and screw rod is installed on the supporting seat by swivel nut, clamps rocking bar and is installed on the screw rod, and the lower surface of screw rod is relative with base, forms the clamping to sample.
Use when originally tearing platform, an end of sample is clamped in the clamp system, the other end is stuck in the card seam of tearing rocking bar, rotating rocker, the resistance spot welding sample can be torn along the solder joint edge, the nugget diameter by measurement is torn can detect its weld strength.At the sample of different size specification, can realize tearing of various resistance spot welding samples by changing the width of clamp system interior space dimension and rocking bar card seam.
The utility model is simple in structure, it is little, easy to use to take up room, and can be installed on production line and detect with line, and input greatly reduces cost.
Description of drawings

Fig. 2 is the structural representation of clamp system wherein
Among the figure: 1 worktable, 2 clamp systems, 3 samples, 21 swivel nuts, 22 supporting seats, 23 screw rods, 24 clamping rocking bars, 25 bases, 4 rocker bearings, 5 are torn rocking bar, 51 card seams
Embodiment
Referring to Fig. 1, Ben Jianyi resistance spot welding sample is torn platform and is comprised worktable 1, clamp system 2, rocker bearing 4, tears rocking bar 5 etc.Clamp system 2 is fixed on the worktable 1 by certain position with rocker bearing 4, tears rocking bar 5 and is installed on the rocker bearing, and its top has one to clamp the card seam 51 of tearing sample, and the position of card seam 51 is relative with the position of clamp system.Sample 3 one ends are sandwiched in the card seam 51, and two 1 end cups are clipped in the clamp system 2.
Referring to Fig. 2, clamp system 2 comprises swivel nut 21, supporting seat 22, screw rod 23, clamps rocking bar 24, base 25.Supporting seat 22 is installed on the base 25, and swivel nut 21 is welded on the supporting seat 22, and screw rod 23 is installed on the supporting seat 22 by swivel nut 21, clamps rocking bar and is installed on the screw rod 23, and the lower surface of screw rod 23 is relative with base 25, and sample 3 is clamped.
During operation, an end of the sample among Fig. 23 is put on the base 25 of clamp system 2, promoted to clamp rocking bar 24 by direction as shown and make screw rod 23 rotations, allow it that sample 3 is pressed on the base 25.The other end of sample 3 is put into the card seam 51 of tearing rocking bar 5, promote to tear rocking bar 5 by the direction as shown F that exerts oneself, its end that snaps in the sample of card seam is distorted along with the rotation of rocking bar 5, behind certain rotational angle, the distortion of sample 3 welds reaches the tension limit and ruptures, promptly reached the effect of tearing sample, as shown in Figure 1.The nugget diameter of tearing by measurement, thus its weld strength detected.
