Description

Technical Field

[0001] The invention belongs to the technical field of aluminum alloy plate processing, and particularly relates to a device and a method for detecting the anti-cracking performance of an aluminum alloy plate. Background Art

[0002] When processing aluminum alloy plates, it is necessary to test their crack resistance. Generally, they are fixed and clamped on the test plate, and the impact head is controlled by the telescopic cylinder above to hit the aluminum alloy plate to observe whether it breaks. However, the existing method has a large device volume and requires a long extension and retraction length. The force after the impact will be transmitted to the fixed seat, causing slight damage to the fixed seat. After a long time of use, the fixed seat needs to be replaced, which has high maintenance costs and poor practicality. This phenomenon has become a problem that needs to be solved urgently by people in this field. Summary of the invention

[0003] The purpose of the present invention is to provide a device and method for detecting the anti-cracking performance of aluminum alloy plates in accordance with the existing material collection device, so as to solve the problems raised in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a device for detecting the crack resistance of an aluminum alloy plate and a detection method thereof, comprising an outer shell, characterized in that: an anti-crack detection impact head is provided on one side of the outer shell, an arched fixing seat is fixed on one side of the outer shell by welding, a square accommodating groove is provided inside the arched fixing seat, a top motor is fixed between the upper and lower inner walls of the square accommodating groove by welding, an output end of the top motor is connected with an output shaft through a coupling, a support rod is fixed on one side of the output shaft by welding, an elastic support rod is movably connected to one side of the support rod by a hinge, a clamping block is installed at one end of the elastic support rod, an aluminum alloy plate is fixed by clamping between the two clamping blocks, a plate placement groove is provided on one side of the arched fixing seat, when in use, the top motor is started, so that its output shaft rotates and drives the support rod to a suitable angle, at which time the aluminum alloy plate is clamped, and at this time the elastic support rod can be deformed when subjected to a large force, effectively alleviating the impact force on the aluminum alloy plate itself, and this relief method has little effect on the arched fixing seat.

[0005] The present invention further describes that a wire harness motor is fixed to one side of the support rod by welding, and a tightening wire is wound around the output end of the wire harness motor. One end of the tightening wire is connected to one end of the elastic support rod. The wire harness motor is driven to move so that the tightening wire is tightened and loosened. At this time, the curvature of the elastic support rod can be adjusted according to the size of the aluminum alloy plate so that the clamping is at a suitable value.

[0006] The present invention further illustrates that an outer shell is fixed to one side of the arch fixing seat by welding, a jet cylinder is fixed to the inner wall of the outer shell by welding, an output end of the jet cylinder is fixedly connected to a four-corner connecting pipe by welding, an anti-crack detection impact head is provided on one side of the outer shell, the anti-crack detection impact head is adjacent to the four-corner connecting pipes, and by driving the jet cylinder to operate, the four-corner connecting pipes can be filled with gas, and an impact force is applied to the anti-crack detection impact head, which can effectively save the volume of the device, and can carry out the anti-crack performance test without the need for a telescopic push rod and other long-sized structures, thereby saving the device cost and being easy to carry.

[0007] The present invention further illustrates that a winding motor is fixed to one side of the outer shell by welding, and the output end of the winding motor is connected to a winding reel through a coupling, and the outside of the winding reel is connected to an elastic connecting rope by winding, and one end of the elastic connecting rope is connected to the anti-crack detection impact head. By driving the winding motor to work, the anti-crack detection impact head can be brought back to its original position by using the winding reel at the end of the impact, and at the beginning of spraying, a certain pre-tightening force is given to the winding reel, so that the anti-crack detection impact head and the four-corner connecting pipes can fit more closely, thereby improving the spraying stability.

[0008] The present invention further illustrates that the inner wall of the outer shell is movably connected with a circular toothed disk through a bearing, and an acceleration motor is arranged on one side of the circular toothed disk. The acceleration motor is fixed to the inner wall of the outer shell by welding, and the output end of the acceleration motor is connected with a driving gear through a coupling, and the driving gear is meshed with the circular toothed disk. One side of the circular toothed disk is in contact with the anti-crack detection impact head. By starting the acceleration motor, the driving gear can be driven to rotate, so that the circular toothed disk has a certain rotation speed through the meshing action, thereby driving the anti-crack detection impact head itself to rotate, so that it is convenient to impact while rotating, and measure the anti-crack performance of both direct impact and rotational impact.

[0009] The present invention further illustrates that a through hole is provided on the circular toothed disc, and the through hole is interconnected with the four-corner connecting tubes; an inclined card block is evenly installed on one side of the circular toothed disc; an inclined card slot is evenly provided on one side of the anti-crack detection impact head; the inclined card block and the inclined card slot cooperate with each other; when in use, the circular toothed disc is driven to rotate, and the mutual meshing effect of the inclined card block and the inclined card slot can be utilized to give a stronger force to drive the anti-crack detection impact head to rotate; at this time, the rotation is not driven solely by friction, and the driving effect is good.

[0010] The present invention further illustrates that the outer wall of the anti-crack detection impact head is evenly installed with protective airbags, and the interior of the protective airbags is filled with sodium azide particles. When the anti-crack detection impact head hits the aluminum alloy plate, the protective airbag will be subjected to impact force, causing the sodium azide particles inside to decompose under the force, which will release nitrogen and promote the expansion of the protective airbag, thereby preventing debris or fragments generated by the breakage of the aluminum alloy plate, and preventing the anti-crack detection impact head from bouncing off to other places, thereby ensuring the safety of the device.

[0011] The present invention further illustrates that the detection method of the detection device includes:

[0012] S1. Place the aluminum alloy plate into the plate placement slot and start the beam motor to adjust the angle of the elastic support rod;

[0013] S2, start the cable motor to drive the cable extension frame and tighten it, adjust the bending size of the elastic support rod until it meets the contour of the aluminum alloy plate, and then clamp the aluminum alloy plate in the clamping block;

[0014] S3, starting the acceleration motor to drive the anti-crack detection impact head to rotate, so that the anti-crack detection impact head has a certain initial rotation speed;

[0015] S4, starting the jet cylinder to make the anti-crack detection impact head spray outward to hit the aluminum alloy plate;

[0016] S5. When hit, the protective airbag expands and covers the aluminum alloy plate to prevent fragments from flying.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention adopts a flexible fixing method, which can allow the aluminum alloy plate to have a certain degree of freedom of movement when it is hit, thereby preventing the fixing seat from being damaged. At the same time, it can adapt to aluminum alloy plates of different sizes, and utilizes a high-pressure gas to launch an impact head. It can provide a larger impact force when the device is small in size, and perform crack resistance testing, thereby saving the size of the device, being easy to carry, and providing a rotational impact force to the aluminum alloy plate, and having various detection methods.

The tightening wire 35 is tightened and loosened by driving the wire harness motor 34 to move. At this time, the curvature of the elastic support rod 36 can be adjusted according to the size of the aluminum alloy plate 5 so that the clamping is at a suitable value.

By driving the air jet cylinder 13 to operate, the four-corner connecting pipe 12 can be filled with gas, and an impact force is applied to the anti-crack detection impact head 2, which can effectively save the volume of the device, and can perform anti-crack performance testing without a structure of a long size such as a telescopic push rod, saving the device cost and being easy to carry;
