Description

Technical Field

[0001] The invention relates to the technical field of casting detection, in particular to a casting strength detection device. Background Art

[0002] Existing strength testing methods for casting parts are mainly divided into two categories: destructive and non-destructive. Destructive testing methods obtain the ultimate strength of the parts by applying external force until the parts finally fail. The most common destructive tests include tensile tests, compression tests, impact tests, etc. These methods are intuitive and easy to operate, and can more accurately evaluate the ultimate load-bearing capacity of parts. Non-destructive testing methods can analyze the internal structure of parts without damaging them, such as ultrasonic testing, X-ray testing, and eddy current testing. These methods can identify material defects and cracks in parts.

[0003] When the strength of castings is tested by destructive testing, the castings are squeezed by a pressure plate and tested by a pressure sensor. The test is intuitive and easy to operate. However, due to the complexity and diversity of casting structures, when extrusion testing is performed on castings with complex shapes, due to the difference in surface shapes, one side is prone to excessive force and the other side is prone to insufficient force, which results in the test results not being able to truly reflect the overall strength of the castings. In addition, when the strength of castings is tested by destructive testing, some castings with structural defects or substandard strength may not be tested. Under the action of pressure, impurities such as debris will be left on the workpiece placement plate, and the strength test of the casting requires testing of multiple samples to ensure the accuracy of the test. Therefore, after the strength test of the previous casting is completed, the workpiece placement plate needs to be cleaned manually. When cleaning manually, it is necessary to use a brush to repeatedly scrape the surface of the test bench and use a collection tool to collect debris and other impurities. Although the operation is simple, it takes a certain amount of operation time, thereby interrupting the continuity of the casting strength test and further reducing the efficiency of the test. For this reason, we propose a casting strength testing device. Summary of the invention

[0050] It should be noted here that the third push rod motor 905 is provided to push the other of the two operating panels 901 .

[0051] Working principle: When performing strength testing on a casting, first place the casting on the placement plate 2, then start the cylinder 106 to push the pressure plate 104 at one end of the push rod 103 to move close to the casting. In the process of the pressure plate 104 moving close to the casting, when the multiple pressure rods 302 on one side of the pressure plate 104 abut against the surface of the casting, the pressure rods 302 will shrink into the installation cavity 303 to varying degrees under the effect of the driving force and the difference in the surface shape of the casting. After each pressure rod 302 fully abuts against the surface of the casting, the movement of the cylinder 106 can be stopped.

[0052] Then, the first push rod motor 606 is started, and under the driving force and the guiding action of each T-shaped rod 601, each connecting plate 602 on one side of the strip plate 607 is pushed to move. During the movement of each connecting plate 602, the driving plate 603 will be synchronously driven to move. When each driving plate 603 abuts against the inclined surface 604 on one side of the square plate 502, the locking teeth 504 on one side of the locking plate 503 will be pushed to be inserted into the locking groove 505 on the side wall of the pressure rod 302 under the mutual force and the guiding action of the square plate 502, and then the position of the pressure rod 302 is limited under the abutting action of each locking tooth 504;

[0053] After the position of each pressure rod 302 is limited, the cylinder 106 can be used to continue to push the pressure plate 104 to move close to the casting, thereby applying pressure to the casting. While the pressure plate 104 applies pressure to the casting, the casting is pressed at multiple points under the tight action of each pressure rod 302, so that the loading force of the pressure plate 104 on the casting can be evenly distributed on the sample. When the pressure reaches a certain level, the sample will be deformed or damaged. For a casting made of brittle material, it may suddenly break, while for a ductile material, it may first yield and then be gradually flattened. By using the pressure sensor 105 to record the pressure at different stages, a compressive stress-strain curve can be obtained, thereby determining the strength indicators such as the compressive strength and yield strength (if there is an obvious yield stage) of the casting material. These indicators can help evaluate the bearing capacity and strength characteristics of the casting when it is subjected to a compressive load. Therefore, under the uniform distribution of multiple pressure rods 302, uniform pressure is applied to the sample, thereby improving the accuracy of the strength detection of the casting.

[0054] After the strength test of the casting is completed, the cylinder 106 is used to drive the pressing plate 104 away from the sample. After the pressing plate 104 moves to the full distance, the second push rod motor 904 and the third push rod motor 905 are started to move the support rods 902 on the two operating plates 901 out of the support holes 906 on the placement plate 2. Then the second rotating motor 803 is started to drive the rotating rod 802 to rotate under the meshing transmission of the first gear 804 and the second gear 805. After the placement plate 2 rotates, the support assembly is used to support the placement plate 2 again.

[0055] After the used side of the placement plate 2 is rotated to the side away from the pressure plate 104, the next sample to be tested can be placed on the placement plate 2 for strength testing. In the process of performing strength testing on the next sample to be tested, the first rotating motor 706 can be started to drive the screw rod 705 to rotate. Under the threaded engagement transmission action of the screw rod 705 and the sliding plate 702 and the guiding action of the sliding groove 701, one side of the cleaning plate 704 slides with the use surface of the placement plate 2. At the same time, under the action of the extrusion assembly, the cleaning plate 704 is abutted against the surface of the placement plate 2. Then, under the movement of the cleaning plate 704, the surface of the placement plate 2 is automatically cleaned without the need for the inspection personnel to stop the machine for cleaning. The operation is simple and the implementation is convenient. While ensuring the cleaning quality of the placement plate 2, the continuity of the strength detection of the casting is guaranteed, thereby improving the efficiency of the detection of the casting.
