Embodiment Construction

[0016] This embodiment is a device for measuring the pouring amount of engine propellant.

[0017] Such as figure 2 As shown, the engine pouring propellant measuring device 1 includes a nut 4 , a positioning plate 5 , a measuring rod 6 and a measuring disc 7 . There are scale lines on the surface of the shaft at the top of the measuring rod 6, and every small grid scale line is spaced at 1mm, 60 small grids in total. Every 10 small grids is a large grid, marked with English letters a~j respectively. The positioning plate 5 is sleeved on the upper part of the measuring rod, and is slidably fitted with the measuring rod. The nut 4 is installed on the upper end surface of the measuring rod 6 , and the measuring disk 7 is welded on the lower end surface of the measuring rod 6 .

[0018] The positioning plate 5 is a square thin aluminum plate, and there is a through hole for installing the measuring rod 6 at the geometric center. The through hole is surrounded by 6 observation ...

Abstract

The invention provides a device for measuring the pouring mount of a motor propellant. The device comprises a nut, a positioning plate, a measuring rod and a measuring plate; a scale line is formed in the surface of the upper part of the measuring rod; the positioning plate sleeves the upper part of the measuring rod and is in sliding match with the measuring rod; the nut is mounted on the upper end surface of the measuring rod; the measuring plate is welded on the lower end surface of the measuring rod; the scale line in the surface of the measuring rod body includes 60 small grids which are arranged at intervals of 1mm; every ten small grids form a large grid; each grid is marked with English letters from a to j. According to the device, the level of the propellant is measured after pouring the propellant of a combustion chamber and before inserting a core, so that the pouring quality of the propellant of the combustion chamber can be quickly detected, and the reject ratio of the product is lowered down from 4% to 0%.

Description

technical field [0001] The invention belongs to the technical field of solid rocket motors, and relates to a device for measuring the pouring amount of a certain type of propellant. Background technique [0002] The pouring of a certain type of solid propellant is mainly to pour the weighed propellant into the pre-assembled shell through vacuum blanking, and then perform the core inserting operation to squeeze the propellant into the cavity between the shell and the mandrel Inside, after the mandrel inserts the core in place, it is cured, and the mandrel is pulled out after curing to ensure that the shape and quality of the propellant are consistent with the design requirements. [0003] Before pouring, place a group of pre-assembled shells in the pouring cylinder for vacuuming. After the vacuum degree meets the process requirements, the pre-weighed propellant is added into the hopper, and the propellant in the hopper is degassed through the flower plate by controlling the ...
