Description
Technical Field
The utility model relates to an automotive electrical appliance field, in particular to terminal ultrasonic bonding peeling strength test fixture. The method is used for testing the stripping force of the ultrasonic welding product of the wire harness in the production process of the automobile wire harness.
Background
With the development of automobile electrical appliance technology, ultrasonic welding technology is applied to automobile wire harnesses. Most ultrasonic welding in wire harnesses adopts ultrasonic welding connection between wires, a peeling force test fixture of the ultrasonic welding connection is shown in figure 1, the tested wires are perpendicular to the longitudinal axis of a welding point and form an angle of 180 degrees, and the wires are clamped according to the direction shown in the figure.
The wire harness is also provided with another ultrasonic welding technology, namely an ultrasonic welding connection mode between a terminal and a wire, and when the peeling force performance of the wire harness is tested, the original clamp is not suitable for the peeling force test requirement of a novel welding product, and at present, the field is blank. It is necessary to redesign a jig to match the new product.
Disclosure of Invention
An object of the utility model is to provide a terminal ultrasonic bonding peel force test fixture has solved prior art and can not carry out the technical problem fixed to the solder joint. The utility model discloses anchor clamps comprise two clamp splices, are called fixed clamp splice and remove the clamp splice. Two nuts are arranged on each clamping block, the edge of a welding spot is firstly inserted into the fixed clamping block to fasten the nuts of the fixed clamping block, and then the edge of the other side of the welding spot is inserted into the movable clamping block to fasten the nuts of the movable clamping block. After the edges of two sides of a welding spot of the sample are fastened, the clamp assembled with the sample is connected to a tensile machine through an adapter and a fixing nut, one end of a lead of the sample is erected and fixed on a longitudinal axis of the tensile machine, and then the stripping force test can be carried out.
The above object of the utility model is realized through following technical scheme:
the terminal ultrasonic welding stripping force test fixture comprises a fixture base 5, a fixed clamping block 1, a movable clamping block 3, a clamp base 5 and a clamp nut 4, wherein the fixed clamping block is arranged on the fixture base 5 and is fastened through a fixed clamping block nut 2; the adapter 7 is fixed on the clamp base 5 through a fixing rod 8 and a fixing nut 6.
The fixed clamping block 1 and the movable clamping block 3 are used for fixing the welding point edge of the ultrasonic welding sample piece 9 respectively.
