[0002] Carbon fiber is an indispensable key strategic material in the current aerospace fields such as large aircraft and satellites, and new energy fields such as hydrogen energy, photovoltaics, and wind energy. Prepreg refers to an intermediate of a composite material made by impregnating a matrix material in a reinforcing fiber. There are many kinds of matrix materials, such as resin, metal, rubber, ceramic, etc., and there are also many reinforcing fibers, such as carbon fiber, glass fiber, aramid fiber, etc. The performance advantages of carbon fiber filaments themselves are low density, high strength, good durability, etc., and after being prepared into carbon fiber prepreg, some characteristics of resin are integrated: good mechanical properties, few product defects, precise control of fiber volume content, and good consistency of performance and processing characteristics.

[0003] In order to make the viscosity of the prepreg meet the requirements, a tooling that can detect its viscosity is needed. However, the traditional detection tooling is large in size, occupies a large space and is not convenient for storage; it is heavy and inconvenient to operate, and the tooling cost is high. Utility Model Content

[0004] In order to solve the technical problems existing in the background technology such as the large size of the traditional prepreg testing tooling and the inconvenience in storage, the purpose of the utility model is to provide a testing tooling that can solve the above problems.

[0006] When the inspection tooling needs to be assembled, first fix the crossbeam between the two bases, and a frame is fixed on the base, so that a space for fixing the placement plate is formed between the crossbeam and the frames on both sides, and the crossbeam serves to connect and fix the two adjacent bases and support the placement plate. The placement plate is fixed on the frame by a fixed structure to prevent it from tilting and falling. After the inspection tooling is assembled, a release cloth is pasted on the placement plate and a prepreg impregnated with a certain proportion of matrix material and reinforcing fiber is pasted. An external force is manually applied to make the prepreg fall off, and the viscosity of the prepreg is judged according to the degree on the force gauge to determine whether it meets the standard. After the inspection is completed, the crossbeam is removed from the base for easy collection after disassembly without taking up storage space. According to the needs of the inspection, a crossbeam and a placement plate of corresponding size can be used without having to replace all the components of the inspection tooling, which has stronger functionality and adaptability and reduces the cost of the tooling.

[0007] Further, the fixing mechanism is a slot, the frame is provided with a slot, the two sides of the placement plate are inserted into the slot, and the bottom of the placement plate abuts against the crossbeam. The frame is vertically fixed to the base, the slot is vertically provided, the two sides of the placement plate are inserted into the slot, the position of the crossbeam corresponds to the position of the slot, and the bottom of the placement plate abuts against the crossbeam, which plays a supporting role for the placement plate.

[0008] Furthermore, the fixing structure further includes a fixing hole and a fixing bolt. The slot is provided with a fixing hole, and the fixing bolt is installed in the fixing hole to lock the placement plate. In order to solve the shaking of the placement plate in the slot, a fixing bolt is further added. After the fixing bolt is tightened into the fixing hole, it has a locking effect on the placement plate to prevent it from shaking.

[0009] Furthermore, the crossbeam has a placement groove, and the bottom of the placement plate is clamped in the placement groove. The placement groove position corresponds to the slot position, and the bottom of the placement plate is limited in the placement groove on the crossbeam, which can also limit its shaking problem and also play a good role in stable support.

[0010] Furthermore, the cross beam includes a support plate and a support beam, there are two support beams, the support plate is located between the two support beams, there is a distance between the support plate and the upper edge of the support beam, and the placement groove is formed between the support plate and the two support beams. The bottom of the placement plate abuts in the placement groove, that is, abuts on the support plate, and the upper edges of the support beams on both sides of the support plate are higher than the support plate, which plays a role in limiting the placement plate.

[0011] Furthermore, the end of the support beam protrudes from a placement slot, the base is provided with a mounting slot, the end of the support beam is installed in the mounting slot, and the support plate is flush with the base. In other words, the end of the support beam is longer than the end of the support plate, and two separated mounting slots are correspondingly provided on the base, and the two mounting slots are fixed more stably. The position of the support plate corresponds to the position of the slot, and the height of the support plate is flush with the height of the base, and the two sides of the placement plate are inserted into the slot, and its bottom can also abut on the support plate.

The bolts are used to fix the detection tooling when it is necessary to install it, and can be removed when it is necessary. The operation is convenient and the fixing effect is stable.

[0013] Furthermore, reinforcing ribs are installed between the frame and the base. The placement plate is generally a steel plate with a large weight. The frame is not fixed firmly on the base and can be easily bent by it. Adding the reinforcing ribs can improve the fixing effect of the frame and withstand the lateral pressure of the steel plate.

[0014] Furthermore, the reinforcing ribs are installed on both sides of the frame to ensure that both sides of the frame have sufficient supporting force.

[0015] By adopting the above technical solution, the utility model has the following beneficial effects:
