Technical Field
The utility model relates to the technical field of mechanical property detection application, in particular to a slotting tool device for a pulling and supporting test sample of an aluminum alloy composite material.
Background
When the pull-off test of the C919 large airplane slat leading edge and trailing edge component materials is carried out, the sample needs to be colored, two cutting marks are scribed on the front surface and the back surface of the sample in the scribing process, two scratches are cut on the sample along the cutting marks in a clamping mode, and then the sample is installed on testing equipment for the pull-off test. At present, the processing of scratches has the following disadvantages: the current clamping is to directly clamp a sample for cutting (see fig. 5), an extended cantilever is easy to shake during cutting, the precision of a cut section is affected, and the cutting depth and the distance between two scratches are difficult to control; in addition, the colored scribe lines are prone to cause visual errors, which affect the positional accuracy of the two scratches. Therefore, the existing process is difficult to guarantee, waste products are easily generated, material waste is caused, the production progress is influenced due to the high rejection rate, and a large amount of harmful dust is generated due to repeated trial production, so that the physical and mental health of staff is influenced.
SUMMERY OF THE UTILITY MODEL
The purpose of the utility model is: the utility model provides a slotting tool device of aluminum alloy composite material pulling and supporting test sample. The utility model has the characteristics of simple structure, convenient operation, high processing precision and material saving.
The technical scheme of the utility model is as follows: a slotting tool device for a test sample of an aluminum alloy composite material pulling and supporting comprises a base with a long strip-shaped structure, wherein a sample placing groove is formed in the top surface of the base along the length direction, a cutting groove I and a cutting groove II are respectively formed in two cross sections perpendicular to the length direction of the base, the cutting groove I is formed in the opening side of the sample placing groove, and the cutting groove II is formed in the back side of the opening of the sample placing groove; depth h of cutting groove IⅠIs less than the depth H of the sample placing groove and the depth H of the cutting groove IIⅡIs larger than the thickness delta of the bottom plate of the sample placing groove.
In the slotting tooling device for the aluminum alloy composite material pulling and supporting test sample, the slotting tooling device further comprises a torsion spring, and two support arms of the torsion spring are clamped on two sides of the bottom plate of the sample placing groove.
In the slotting tooling device for the aluminum alloy composite material pulling and supporting test sample, the length of the sample placing groove is equal to the length of the sample.
In the slotting tool device for the aluminum alloy composite material pulling and supporting test sample, the base is clamped and fixed by the vice.
In the slotting tooling device for the aluminum alloy composite material pulling and supporting test sample, the cutting groove I has a width wⅠIs 1 mm.
In the slotting tooling device for the aluminum alloy composite material pulling and supporting test sample, the cutting groove II has the width wⅡIs 1 mm.
The utility model has the advantages that: according to the utility model, the sample is placed in the sample placing groove and then clamped and fixed, so that the shaking of the sample during cutting is effectively prevented, and the processing precision of the section is improved; meanwhile, the scratches on the sample are processed through the cutting grooves I and II arranged on the two sides of the sample placing groove, so that the scratch cutting depth and the scratch distance can be accurately controlled, and the processing precision is effectively improved; meanwhile, the structure also omits a coloring and scribing process, so that the operation is simpler and more convenient; moreover, the structure greatly reduces the rejection rate, under the condition of normal operation, the utility model hardly generates waste products, effectively saves materials, reduces repeated trial production, and reduces the generation of harmful dust in reply.
In conclusion, the utility model has the characteristics of simple structure, convenient operation, high processing precision and material saving.
