Background
With the accumulation of engineering practices for many years, the blasting engineering technology in China is well developed. In order to ensure the smooth progress of engineering, it is very important to know the dynamic mechanical properties of various materials. At present, Hopkinson bars are generally adopted at home and abroad to research the dynamic mechanical properties of various materials. In the process of the Hopkinson bar test, it is important to ensure that the whole of the bullet, incident bar, sample, transmission bar, and absorption bar is closely attached and on the same axis and kept horizontal. At present, the gap between the two binding surfaces of the rod is repeatedly touched by fingers, and the visual angle is kept horizontal by visual observation, so that whether the rod system is coaxial and horizontal can be roughly judged. However, this method has high requirements on the experience of the operator, is highly subjective, and lacks quantification of the leveling effect.
SUMMERY OF THE UTILITY MODEL

The utility model provides an auxiliary leveling instrument for hopkinson pole, including lower surface horizontally base, the baffle of internal surface vertical to and fix the vertical slide rail on the base, install movable horizontal laser range finder and movable horizontal slide rail on vertical slide rail in proper order, install the movable vertical laser range finder on movable horizontal slide rail.
The vertical slide rail, the movable horizontal laser range finder, the movable horizontal slide rail and the movable vertical laser range finder are all located on the same plane.
The movable horizontal laser range finder, the movable horizontal sliding rail and the movable vertical laser range finder all adopt limit nuts to adjust and fix the positions of the movable horizontal laser range finder, the movable horizontal sliding rail and the movable vertical laser range finder. The specific operation is as follows: the position of the limiting nut can be adjusted in the direction limited by the sliding rail by unscrewing the limiting nut; the position of the limiting nut can be fixed by screwing the limiting nut.
The movable horizontal laser range finder and the movable vertical laser range finder are provided with independent switches, are powered by built-in power supplies and are provided with electronic display screens to display range reading.
In order to keep the whole Hopkinson bar auxiliary leveling tool stable during leveling, the center of gravity of the tool is designed at the base.
The utility model has the advantages that:
the leveling tool is simple in structure, simple and convenient in use method, easy to operate and convenient to move and disassemble, and can quantitatively measure the horizontal and vertical distances between the leveling tool and a rod system, so that reference is provided for auxiliary leveling.

Detailed Description
In order to make the objects, operation and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.
An auxiliary leveling tool for a Hopkinson bar mainly comprises a base (1), a baffle (2), a fixed vertical sliding rail (3), a movable horizontal sliding rail (4), a movable horizontal laser range finder (5) and a movable vertical laser range finder (6).
The operation process of the auxiliary leveling tool for the Hopkinson bar in the embodiment is carried out according to the following steps:
the method comprises the following steps: before use, the power supplies of the movable horizontal laser range finder (5) and the movable vertical laser range finder (6), the laser generating and sensing device (10) and the electronic display screen (11) are checked to determine whether the devices work normally. If the problem occurs, the corresponding part is replaced in time; and if the operation is normal, performing the step two.
Step two: the leveling sequence of the whole Hopkinson bar system is determined according to the sequence of bullets, incident bars, transmission bars and absorption bars. The whole rod system consists of cylindrical straight rods with the same diameter and material.
Step three: the bullet, the incident rod, the transmission rod and the absorption rod are tightly attached together under the action of the supporting and limiting device. The bullet is in the horizontal launching tube and is tightly combined with the launching tube, and the axis of the bullet is relatively fixed and horizontal, so the axis of the bullet is taken as a reference horizontal axis.
Step four: and adjusting the supporting and limiting device of the incident rod to ensure that the joint surfaces of the bullet and the incident rod are completely aligned and superposed.
Step five: with utility model's base keep flat on the base of hopkinson pole device, ensure that its bottom surface and base laminate completely, support the side edge of base with the baffle simultaneously, just so can make the central axis of the whole rod system of plane perpendicular to at fixed vertical slide rail (3), movable horizontal laser range finder (5), movable horizontal slide rail (4) and movable vertical laser range finder (6) place.
Step six: measure its level and vertical interval with the bullet with utility model auxiliary leveling instrument. The specific operation is as follows: the positions of the movable horizontal laser distance measuring instrument (5) and the movable vertical laser distance measuring instrument (6) are adjusted and fixed by twisting the limit nuts (7), (8) and (9), so that the rays emitting laser are all aligned to the cylindrical axis of the bullet. And starting the movable horizontal laser distance meter (5) and the movable vertical laser distance meter (6), measuring the distances from the movable horizontal laser distance meter to the uppermost end and the outermost end of the bullet, reading and recording through an electronic display screen (11), and simultaneously taking the two distances as reference distances for subsequent adjustment.
Step seven: according to the reference distance, adjust the supporting stop device of incident pole, transmission pole and absorption pole in proper order, measure its distance to incident pole, transmission pole and absorption pole with utility model auxiliary leveling instrument, let the reading unanimous with the data that record before. Thus, the whole rod system is ensured to be completely consistent with the horizontal and vertical intervals of the auxiliary leveling tool of the utility model, and the axis of the rod system is coincided with the axis of the bullet, thereby ensuring the coaxial level of the whole rod system.
