Description

Technical Field

[0001] This application relates to the technical field of engineering test equipment, and particularly relates to an automated compression testing machine. Background Art

[0002] A test press is a commonly used equipment for engineering material testing, generally used to measure the compressive strength of concrete, etc. Generally speaking, engineering laboratories usually conduct concrete compressive strength tests in batches, and a large number of test blocks need to be detected in one test. The concrete compressive test will cause the surface of the concrete to spall, and the spalled concrete debris will remain on the surface of the test bench, affecting the continuity of the test. At present, engineering laboratories are gradually being improved towards intelligent laboratories. Although the test bench can be cleaned manually, this also goes against the original intention of the transformation of intelligent laboratories. In addition, the surface of the concrete to be tested is often accompanied by components such as oil stains that are not easy to clean, and the test benches of the existing technologies cannot take into account both automation and cleaning degree at the same time. Summary of the Invention

[0003] The present invention provides an automated compression testing machine, which can automatically push the test block to the test position and automatically clean the surface of the test bench.

[0004] The technical solution of this application is as follows:

[0005] An automated compression testing machine includes a test bench and a press. The test bench is successively divided into a preparation area, a loading area, and a discharging area according to the position where the test block loading process is located. A set of guide rails and lead screws are respectively arranged on both sides of the test bench. The guide rails and the lead screws are connected by a slider, and the slider extends downward to the surface of the test bench and is connected to a propulsion mechanism close to the surface of the test bench through a deflector plate. The propulsion mechanism includes a pair of clamping plates and a scraper disposed between the clamping plates. The scraper is in contact with the surface of the test bench.

[0006] Shells covering the guide rails and the lead screws are respectively arranged on both sides of the test bench, and a rodless cylinder is arranged on the surface of the shell above the loading area. The rodless cylinder is provided with a reciprocating movable connecting plate, and the connecting plate is connected with a brush with bristles facing upward.

[0007] Further, the discharging area has a downward slope.

[0008] Further, the deflector plate includes a rectangular connecting portion and a wedge-shaped collecting portion, and the connecting portion is connected to the slider.

[0009] Further, the preparation area is provided with a rubber pad.

[0010] Due to adopting the above technical solution, the beneficial effects of this application are as follows:

[0011] 1. This application can clean the surface of the test bench. In this application, the preparation area is used to place test blocks, and the placement method can be manual placement or placement by a robot. Before placing the test blocks, the propulsion mechanism can move from the preparation area to the discharge area once in advance to pre-clean the possible residues. After the test blocks are placed, the propulsion mechanism pushes the test blocks to the loading area through the control mechanism. After the loading is completed, the concrete test blocks will exfoliate. At this time, the propulsion mechanism is restarted from the preparation area, pushes the test blocks to the discharge area, and at the same time aggregates the generated residues through the diversion plate and pushes them into the discharge area.

[0012] 2. This application can clean the pressure plate. Since it may be necessary to apply release oil or other functional greases to the concrete test blocks during the curing process, when the pressure plate is in close contact with the concrete test blocks, stubborn oil stains or debris will adhere to the surface of the pressure plate. In this application, by setting a rodless cylinder and cooperating with a connecting plate, the brush can be driven to reciprocate, sweeping the oil stains or debris on the pressure plate to the surface of the test bench, and then the propulsion mechanism collects and cleans them.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Based on the background art described above, as shown in the attached Figure 1 ~attached Figure 4As shown in the figure. The present application provides an automatic pressure testing machine, which includes a test bench 1 and a press 2. The test bench 1 is sequentially divided into a preparation area 3, a loading area 4, and a discharging area 5 according to the position where the test block loading process is located. A set of guide rails 6 and lead screws 7 are respectively arranged on both sides of the test bench 1. The guide rails 6 and the lead screws 7 are connected by a slider 8, and the slider 8 extends downward to the surface of the test bench 1 and is connected to a propulsion mechanism 10 close to the surface of the test bench 1 through a diversion plate 9. The propulsion mechanism 10 includes a pair of clamping plates 10-1 and a scraping plate 10-2 arranged between the clamping plates 10-1. The scraping plate 10-2 is attached to the surface of the test bench 1. Shells 11 covering the guide rails 6 and the lead screws 7 are respectively arranged on both sides of the test bench 1, and a rodless cylinder 12 is arranged on the surface of the shell 11 above the loading area 4. The rodless cylinder 12 is provided with a reciprocating movable connecting plate 13, and the connecting plate 13 is connected with a brush 14 with bristles facing upward.

[0021] The preparation area 3 is used to place test blocks. In an intelligent laboratory, generally, a robotic arm automatically takes test blocks from a test block placement table and places the test blocks at a fixed position on the test bench 1. In the present application, the fixed position is the middle of the edge of the preparation area 3. After placement, the propulsion mechanism 10 pushes the test blocks into the loading area 4 through a control mechanism. In specific implementation, the control mechanism can be a stepping motor driving the lead screw 7 to rotate, and cooperating with sensors to achieve precise speed and position control.

[0022] Before the test blocks are placed, the propulsion mechanism 10 first reciprocates from the preparation area 3 to the discharging area 5 once to clean up any possible remaining debris, and then the concrete test blocks are placed. After the concrete test blocks are placed, the propulsion mechanism 10 pushes the test blocks into the loading area 4 for loading. During the loading process, concrete spalling will occur. After the loading is completed, when the test blocks are pushed into the discharging area 5, the residues are cleaned up at the same time.

[0023] Before the propulsion mechanism 10 processes the test blocks after the test, the rodless cylinder 12 can control the brush 14 to reciprocate through the connecting plate 13 to clean the surface of the pressure plate, and the fallen debris enters the discharging area 5 along with the propulsion mechanism 10.

[0024] In the present application, the scraping plate 10-2 is arranged between a pair of clamping plates 10-1, and the lower edge of the scraping plate 10-2 can be subjected to cutting treatment to reduce the resistance of the reciprocating motion.

[0025] As a preferred embodiment of the present application, the discharging area 5 has a downward inclined surface 15. A waste bin for collecting the test blocks after the test can be placed below the test bench 1. After the propulsion mechanism 10 pushes the test blocks into the discharging area 5, they slide into the waste bin through the inclined surface 15, which is convenient to use.

[0026] As a preferred embodiment of the present application, the deflector 9 includes a rectangular connecting portion 9-1 and a wedge-shaped collecting portion 9-2. The connecting portion 9-1 is connected to the slider 8. The wedge-shaped collecting portion 9-2 has a flat surface and an inclined surface 15. The flat surface fits against the side surface of the test bench 1 to prevent residue from entering. The inclined surface 15 can gather the residue during the forward movement to reduce the traveling resistance.

[0027] As a preferred embodiment of the present application, the preparation area 3 is provided with a rubber pad. The rubber pad can protect the test bench 1 and prevent the test bench 1 from being scratched and affecting the pushing effect. At the same time, the rubber pad has a soft texture and can fit closely with the squeegee 10-2 to improve the cleaning effect.

[0028] What is not described in the present application can be achieved by adopting or referring to the existing technologies.

[0029] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
