Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of Hopkinson's rod experimental equipment, specifically a spliced guide rail structure for Hopkinson's rod experimental equipment. Background Technology
[0002] The Hopkinson bar apparatus is a core device for studying the dynamic mechanical properties of materials under high strain rates. Its basic principle is to test the dynamic response of a specimen by utilizing the propagation of stress waves in an elastic bar. The coaxiality of the entire apparatus is a critical prerequisite for ensuring the accuracy and reliability of experimental data. If there are coaxiality deviations among components such as the drive device, guide device, incident bar, transmission bar, and absorption device, it will cause distortion of stress wave propagation, produce unnecessary dispersion effects, and induce localized stress concentration at the bar contact interfaces, ultimately severely affecting the reliability of the experimental results.
[0003] Currently, to facilitate the transportation and installation of guide rails, multiple sections of guide rail are typically spliced together. Traditional splicing methods rely heavily on the operator's technical experience, using tools such as levels and dial indicators for repeated manual calibration and adjustment. This method has several significant drawbacks: First, the manual calibration process is tedious, time-consuming, and labor-intensive, resulting in extremely low splicing efficiency; second, the calibration accuracy heavily depends on the operator's subjective experience and skill level, making it difficult to guarantee consistency and high precision in each splicing; and finally, there is a lack of rapid and effective verification methods for the completed splicing. Therefore, this application provides a spliced guide rail structure for Hopkinson's laboratory equipment to solve the above problems. Utility Model Content

This structure is simple, enables rapid and high-precision alignment and splicing of the guide rail, has high splicing efficiency, saves time and effort, reduces reliance on operator experience and skills, and allows for functional verification of the coaxiality of the spliced guide rail using ceramic plates, ensuring the reliability and consistency of each splicing. It is easy to use and effectively solves the problems in the background technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a splicing guide rail structure for Hopkinson's laboratory equipment, including a guide rail, both ends of which are provided with side sliding grooves, and a placement groove communicating with the side sliding groove is opened on the side of the guide rail. A ceramic sheet that can be slidably disposed inside the side sliding groove is placed inside one of the placement grooves. Both ends of the guide rail are provided with positioning holes, and a positioning rod is movably inserted inside the positioning holes.
[0006] As a preferred embodiment of this utility model, an upper sliding groove is provided in the middle of the upper surface of the guide rail.

[0012] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a partial structural schematic diagram of the present invention.
[0013] In the diagram: 1 guide rail, 2 through hole, 3 upper slide groove, 4 side slide groove, 41 placement groove, 5 ceramic plate, 51 protrusion, 6 positioning hole, 61 guide post, 7 positioning rod, 71 guide groove, 72 exhaust groove. Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-2This utility model provides a technical solution: a splicing guide rail structure for Hopkinson's laboratory equipment, including a guide rail 1. Both ends of the guide rail 1 are provided with side sliding grooves 4, and the side of the guide rail 1 is provided with a placement groove 41 communicating with the side sliding grooves 4. A ceramic piece 5 that can be slidably disposed inside the side sliding groove 4 is placed inside one of the placement grooves 41. By sliding the ceramic piece 5 along the side sliding groove 4, it can be observed that the ceramic piece 5 can move into the side sliding groove 4 of the adjacent guide rail 1. Both ends of the guide rail 1 are provided with positioning holes 6, and positioning rods 7 are movably inserted inside the positioning holes 6. When splicing the guide rail 1, a fixed adjustment support is first installed at the bottom of the guide rail 1, and then two adjacent guide rails 1 are spliced together so that the two ends of the positioning rods 7 are respectively inserted into the positioning holes 6 of the two guide rails 1.
[0016] By cooperating with the positioning hole 6 at the end of the guide rail 1 and the positioning rod 7, a physical hard constraint is provided for the initial docking of the two guide rail sections 1. This can automatically guide the two guide rail sections 1 to quickly reach the preset axial and radial reference positions, greatly reducing the dependence on the operator's personal experience and skills, and simplifying the complex calibration work into a simple plug-in operation.
[0017] After assembly, the coaxiality can be functionally verified by attempting to slide the ceramic piece 5 of one side guide rail 1 into the side slide groove 4 of the other side guide rail 1.
[0018] Furthermore, an upper sliding groove 3 is provided in the middle of the upper surface of the guide rail 1 to facilitate the installation and fixation of other components of the Hopkinson experimental equipment.
[0019] Furthermore, the guide rail 1 has evenly distributed through holes 2 on its side, which reduces the mass of the guide rail 1 and saves materials.
[0020] Furthermore, the ceramic sheet 5 has protrusions 51 on its side to facilitate the pushing and pulling of the ceramic sheet 5.
[0021] Furthermore, the positioning hole 6 is provided with a guide post 61 inside, and the side of the positioning rod 7 is provided with a guide groove 71 corresponding to the guide post 61, so that the guide post 61 slides in a directional manner and does not rotate.
[0022] Furthermore, the side of the positioning rod 7 is provided with exhaust grooves 72 distributed along its length, which facilitates the discharge of gas inside the positioning hole 6 when the positioning rod 7 is inserted into the positioning hole 6.
[0023] When using: When splicing the guide rail 1, first install a fixed adjustment support at the bottom of the guide rail 1, and then splice two adjacent guide rails 1 so that the two ends of the positioning rod 7 are respectively inserted into the positioning holes 6 of the two guide rails 1 and the opposite surfaces of the two guide rails 1 are in contact. Then, the ceramic piece 5 is placed into the placement groove 41, and the ceramic piece 5 is slid along the side sliding groove 4. It is observed that the ceramic piece 5 can move into the side sliding groove 4 of the adjacent guide rail 1. When the ceramic piece 5 can be inserted into the side slide groove 4 of the adjacent guide rail 1, it indicates that the two guide rails 1 have been spliced. When the ceramic piece 5 cannot be inserted into the side slide groove 4 of the adjacent guide rail 1, the fixed adjustment support at the bottom of the guide rail 1 is adjusted until the ceramic piece 5 can be inserted into the side slide groove 4 of the adjacent guide rail 1.
[0024] This utility model has a simple structure and can achieve fast and high-precision centering and splicing of guide rails. It has high splicing efficiency, saves time and effort, reduces reliance on the experience and skills of operators, and can also use ceramic sheet 5 to perform functional verification of the coaxiality of the spliced guide rail 1, ensuring the reliability and consistency of splicing quality each time. It is also easy to use.

Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
