Description

Technical Field

[0001] The invention relates to the technical field of aluminum honeycomb panel detection, and in particular to an auxiliary device for detecting the compressive strength of an aluminum honeycomb panel. Background Art

[0002] Aluminum honeycomb panels are suitable for civil construction, vehicle and ship decoration, etc. They are the application of aviation and aerospace materials in the field of civil construction. The entire processing process is completed in a modern factory, using hot pressing technology. Due to the high thermal conductivity between the aluminum skin and the honeycomb, the thermal expansion and contraction of the inner and outer aluminum skins are synchronized; there are small holes on the honeycomb aluminum skin, so that the gas in the panel can flow freely; the slidable mounting buckle system will not cause structural deformation during thermal expansion and contraction.

[0003] In practical applications, the compressive strength of aluminum honeycomb panels is one of the indicators for evaluating their quality. Existing devices for testing the compressive strength of aluminum honeycomb panels lack the ability to quickly move the aluminum honeycomb panels forward, backward, left, and right, as well as the ability to adjust the compressive test angle of the aluminum honeycomb panels. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the existing device for testing the compressive strength of aluminum honeycomb panels lacks the ability to quickly move the aluminum honeycomb panels forward, backward, left, and right, and lacks the ability to adjust the compressive test angle of the aluminum honeycomb panels. In order to solve the technical problem, an auxiliary device for testing the compressive strength of aluminum honeycomb panels is proposed, including an auxiliary platform;

[0005] The bottom of the auxiliary platform is slidably connected to the sliding base, and a fixing frame is symmetrically arranged on the top of the auxiliary platform. A horizontal plate is connected to the outer side wall of the fixing frame, and a first slide rail is arranged on the horizontal plate. A rotating ring is slidably connected to the first slide rail. The center of the rotating ring passes through and is rotatably connected to a rotating shaft. The rotating shaft passes through and is transferred to the fixing frame and is connected to a fixing device.

[0006] A take-up wheel and a guide wheel are symmetrically arranged in the auxiliary table cavity. The center of the take-up wheel is fixedly connected to the power output end of the motor. A first connecting wire is wound around the take-up wheel. The first connecting wire passes through an opening at the top of the auxiliary table and is connected to a connecting seat of a fixing device. The guide wheel guides the second connecting wire. One end of the second connecting wire passes through another opening at the top of the auxiliary table and is connected to a connecting seat of a fixing device. The other end of the second connecting wire is connected to a slider. The slider is slidably connected to a third slide rail. The third slide rail is arranged in a stretching bin. A fixed seat is arranged in the stretching bin. The fixed seat is connected to a spring, and the spring is connected to the slider.

[0007] Preferably, an angle measuring scale is provided on the outer side wall of the fixing frame.

[0008] Preferably, the fixing device includes a fixing body, a connecting screw passes through and rotates on the fixing body, a knob is connected to the top of the screw, an upper clamping plate is screwed on the upper outer part of the screw circumference, the left end of the upper clamping plate is slidably connected to the second slide rail, the right end of the upper clamping plate passes through the right opening of the fixing body, the lower part of the outer part of the screw circumference is screwed on the lower clamping plate, the left end of the lower clamping plate is slidably connected to the second slide rail, the right end of the lower clamping plate passes through the right opening of the fixing body, and the second slide rail is arranged on the inner wall of the fixing body.

[0009] Preferably, the screw is a double-headed screw with threads on both ends rotating in opposite directions, and the upper clamping plate and the lower clamping plate are respectively screwed to the threads on the upper and lower sides.

[0010] Compared with the existing technology, the beneficial effects of the present invention are as follows: the present invention rotates the knob to drive the screw to rotate, drive the upper clamping plate and the lower clamping plate to move toward each other, clamp the left and right ends of the aluminum honeycomb panel by the upper clamping plate and the lower clamping plate, thereby fixing the left and right ends of the aluminum honeycomb panel, and at the same time, by moving the rotating ring along the first slide rail, the left and right positions of the aluminum honeycomb panel can be adjusted during detection.

[0011] Start the motor to drive the take-up wheel to rotate and take up the wire. Drive the aluminum honeycomb panel forward with the rotating shaft as the axis through the first connection line, so that the aluminum honeycomb panel can be quickly rotated forward at different angles to test the compressive strength of the aluminum honeycomb panel. Rotate the take-up wheel in the opposite direction to release the wire. The spring will immediately shrink when it loses its tension, driving the slider to reset along the third slide rail. Pull the fixing device at the rear side through the second connection line, so that the aluminum honeycomb panel can be quickly rotated backward at different angles to test the compressive strength of the aluminum honeycomb panel.

[0012] By sliding the auxiliary table forward and backward along the sliding base, the front and rear position of the aluminum honeycomb panel can be adjusted during testing.

[0013] The rapid adjustment of the front, back, left, and right positions of the aluminum honeycomb panels and the rapid adjustment of the rotation angle of the aluminum honeycomb panels are realized, thereby improving the efficiency of the compressive strength test of the aluminum honeycomb panels.

The center of the take-up wheel 8 is fixedly connected to the power output end of the motor 9. A first connection line 81 is wound around the take-up wheel 8. The first connection line 81 passes through an opening at the top of the auxiliary platform 1 and is connected to a connecting seat 10 of a fixing device 7. The guide wheel 17 guides a second connection line 18. One end of the second connection line 18 passes through another opening at the top of the auxiliary platform 1 and is connected to a connecting seat 10 of a fixing device 7.

[0023] In order to better assist in detecting the compressive strength of the aluminum honeycomb panel, the present invention also includes an angle scale 31 on the outer side wall of the fixing frame 3. The fixing device 7 includes a fixing body 71, a connecting screw 72 is passed through and rotated on the fixing body 71, a knob 73 is connected to the top of the screw 72, an upper clamping plate 74 is screwed to the upper outer part of the circumference of the screw 72, the left end of the upper clamping plate 74 is slidably connected to the second slide rail 76, the right end of the upper clamping plate 74 passes through the right opening of the fixing body 71, the lower outer part of the circumference of the screw 72 is screwed to the lower clamping plate 75, the left end of the lower clamping plate 75 is slidably connected to the second slide rail 76, the right end of the lower clamping plate 75 passes through the right opening of the fixing body 71, and the second slide rail 76 is arranged on the inner wall of the fixing body 71.

[0024] Working principle: The present invention adjusts the position of the rotating ring 5 according to the length of the aluminum honeycomb panel so that the upper and lower clamps of the fixing device 7 located on the left and right sides can contact the left and right ends of the aluminum honeycomb panel. Turn the knob to drive the screw to rotate, drive the upper and lower clamps to move toward each other, clamp the left and right ends of the aluminum honeycomb panel through the upper clamp 74 and the lower clamp 75, and fix the left and right ends of the aluminum honeycomb panel. At the same time, by moving the rotating ring 5 along the first slide rail 41, the left and right positions of the aluminum honeycomb panel can be adjusted during detection.

By sliding the auxiliary table forward and backward along the sliding base 2, the front and rear position of the aluminum honeycomb panel can be adjusted during the detection.
