Description

Technical Field

[0001] The utility model relates to the technical field of impact test benches, in particular to an impact test bench. Background Art

[0002] Impact test is generally a test method to determine the safety, reliability and effectiveness of military and civilian equipment when subjected to external impact or action. Impact tests in electrical engineering generally include operation impact test, lightning impact test and steep wavefront impact test, which test the insulation strength of electrical equipment.

[0003] When the current impact test bench is in use, after the first impact test, it is very likely to be subjected to a secondary impact due to the rebound effect, which will greatly affect the results of the impact test and may also cause damage or deformation of the test sample. Therefore, we propose an impact test bench to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an impact test bench to solve the problems raised in the above background technology.

[0007] In a further embodiment, two sets of positioning grooves are provided on the side surfaces of the two vertical plates close to each other, and the inner wall of each positioning groove is slidably connected with a positioning plate, and the side surfaces of the two sets of positioning plates close to each other are respectively connected to the left and right sides of the hanging plate.

[0008] In a further embodiment, electric push rods are installed on the side surfaces of the two vertical plates close to each other, and semicircular rings are fixedly connected on the ends of the two electric push rods close to each other.

[0009] In a further embodiment, a partition is fixedly connected to the side surfaces of the two vertical plates that are close to each other, a through groove is formed on the upper surface of the partition, and two buffer pads are fixedly connected to the upper surface of the partition.

[0011] In a further embodiment, a protective pad is fixedly connected to the upper surface of the base.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The device cooperates with the first support plate, the second support plate, the third support plate, the support block and the carrier plate, and utilizes the connection between the first support plate, the second support plate, the third support plate and the support block. When the impact force borne by the carrier plate becomes larger, the angle between the second support plate and the first support plate and the third support plate will change, and the carrier plate will drop at the same time. After the impact head rebounds, it will not collide with the test sample for the second time, thereby avoiding the occurrence of secondary impact, not affecting the impact test effect, and not causing damage or deformation to the test sample.

DETAILED DESCRIPTION

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 In the utility model, an impact test bench includes a base 1, the upper surface of the base 1 is fixedly connected with two vertical plates 19, the side surfaces of the two vertical plates 19 close to each other are fixedly connected with two first support plates 2, the end of each group of first support plates 2 close to each other is connected with a second support plate 15 through a locking bolt, the top of each second support plate 15 is connected with a third support plate 14 through a locking bolt, the top of each third support plate 14 is connected with a support block 17 through a locking bolt, the tops of the two groups of support blocks 17 are commonly fixedly connected with a carrier plate 18, a hanging plate 8 is arranged above the carrier plate 18, a hanging ring 9 is fixedly connected to the upper surface of the hanging plate 8, and an impact head 6 is installed on the bottom surface of the hanging plate 8.

[0021] Two sets of positioning grooves 5 are provided on the side surfaces of the two vertical plates 19 that are close to each other, and a positioning plate 7 is slidably connected to the inner wall of each positioning groove 5. The side surfaces of the two sets of positioning plates 7 that are close to each other are respectively connected to the left and right side surfaces of the hanging plate 8. By utilizing the connection between the positioning plate 7, the hanging plate 8 and the positioning grooves 5, the position of the hanging plate 8 can be stabilized, thereby ensuring the accuracy of the position of the impact head 6 after it falls.

[0022] An electric push rod 11 is installed on the side where the two vertical plates 19 are close to each other, and a semicircular ring 10 is fixedly connected to one end of the two electric push rods 11 close to each other. The semicircular ring 10 can be pushed or retracted synchronously by the set electric push rod 11. When the semicircular ring 10 is closed, the hanging ring 9 can be suspended to stabilize the impact head 6. When the semicircular ring 10 is separated, the impact head 6 will fall.

[0023] A partition plate 3 is fixedly connected to one side of the two vertical plates 19 that are close to each other. A through groove 4 is opened on the upper surface of the partition plate 3. Two buffer pads 13 are fixedly connected to the upper surface of the partition plate 3. The partition plate 3 can be used to support the hanging plate 8 to avoid damage to the device caused by excessive descent of the impact head 6. At the same time, the buffer pad 13 will cushion the falling partition plate 3 to prevent it from serious collision.

[0024] The two vertical plates 19 are bonded with signboards 12 on the side away from each other. The signboards 12 can be used to let the staff know the operation matters to avoid accidents during use.

[0025] A protective pad 16 is fixedly connected to the upper surface of the base 1 , and the protective pad 16 can be used to protect the third support plate 14 and the carrier plate 18 to prevent them from colliding and being damaged with the base 1 .

[0026] The working principle of the utility model is: first, the test sample can be placed on the carrier plate 18, and then the two electric push rods 11 can be started to retract, the two electric push rods 11 will pull the semicircular ring 10 to separate from the hanging ring 9, and the impact head 6 will fall, and the test sample will be impacted during the falling process. After the test sample is impacted, the force borne by the carrier plate 18 will increase, the angle between the second support plate 15 and the first support plate 2 and the third support plate 14 will change, the carrier plate 18 will drop, and the test sample will drop at the same time. After the hanging plate 8 collides and rebounds with the partition plate 3, the falling of the impact head 6 will not contact the test sample again, thereby avoiding a secondary impact, and will not affect the impact test effect, and will not cause damage or deformation to the test sample.
