Description

Technical Field

[0001] The utility model relates to a geometric precision detection tool for the assembly of a solid rocket booster, belonging to the technical field of the assembly of solid rocket boosters. Background Technique

[0002] During the assembly process of a solid rocket booster, not only should all connecting threads be properly matched, but also the geometric precision of the solid rocket booster needs to be ensured, that is, a fixed phase angle should be satisfied between the positioning notch processed on the inner ring of the front head of the booster and the positioning block at the tail of the booster. In the traditional assembly tooling, an operator manually fixes the front head of the booster, and another operator sequentially assembles other components. After the general assembly is completed, a right-angle ruler is used to detect whether the geometric precision in space meets the requirements. The assembly efficiency is relatively low, and there are potential safety hazards. To solve the above problems, an assembly tooling is designed and manufactured. This assembly tooling has the function of detecting geometric precision in space, ensuring that the booster is assembled qualified at one time, and improving the inherent safety of the assembly process. Content of the Utility Model

[0003] The purpose of the utility model is to provide a geometric precision detection tool for the assembly of a solid rocket booster.

[0004] The purpose of the utility model is realized through the following technical solutions:

[0005] A geometric precision detection tool for the assembly of a solid rocket booster of the utility model includes a base, a positioning ring and a positioning key fixed at the center of the upper surface of the base, a fixed rod vertically fixed on the side of the upper surface of the base, a movable rod slidably connected to the upper end of the fixed rod, and a detection head connected to the upper end of the movable rod through a horizontal shaft;

[0006] The positioning ring is an annular part with an inner diameter matching the outer diameter of the front head of the booster. Screw connection holes matching the front head of the booster are processed on the side wall of the positioning ring; the phase angle of the positioning key and the fixed rod is matched with the phase angle between the positioning notch on the inner ring of the front head of the booster and the positioning block at the tail of the booster;

[0007] A positioning notch matching the outer shape of the positioning block at the tail of the booster is processed at the outer end of the detection head;

[0008] One end of the front head of the booster is placed downward in the positioning ring on the upper surface of the base, so that the positioning notch on the inner ring of the front head of the booster is circumferentially positioned through the positioning key, and the side wall of the front head of the booster is fixed to the positioning ring by screws; by sliding the movable rod, the shaft connection end of the detection head is made flush with the positioning block at the tail of the booster, and by observing whether the positioning notch of the detection head can be inserted into the positioning block at the tail of the booster, it can be judged whether the fixed phase angle requirement is met between the positioning notch processed on the inner ring of the front head of the booster and the positioning block at the tail of the booster.

[0009] Beneficial effects

[0010] The detection tooling of the utility model not only improves the intrinsic safety of the assembly process, optimizes the manual fixing of the booster by the operator to the tooling fixing, detects the phase angle requirements of different components of the solid rocket booster, ensures the qualification of one-time assembly, and effectively improves the assembly efficiency of the booster.

[0014] The content of the utility model will be further described below in conjunction with the drawings and embodiments.

[0015] Embodiment

[0016] As Figure 1 、 2 shown, a geometric accuracy detection tooling for assembling a solid rocket booster of the utility model includes a base 1, a positioning ring 2 and a positioning key 6 fixed at the center of the upper surface of the base 1, a fixed rod 3 vertically fixed on the side of the upper surface of the base 1, a movable rod 4 slidably connected to the upper end of the fixed rod 3, and a detection head 5 connected to the upper end of the movable rod 4 through a horizontal shaft;

[0017] The positioning ring 2 is an annular part with an inner diameter matching the outer diameter of the front head of the booster, and screw connection holes matching the front head of the booster are machined on the side wall of the positioning ring 2; the phase angle of the positioning key 6 and the fixed rod 3 is matched with the phase angle between the inner ring positioning notch of the front head of the booster and the tail positioning block of the booster;

[0018] A positioning notch matching the outer shape of the tail positioning block of the booster is machined at the outer end of the detection head 5.

[0019] When detecting the geometric accuracy of a solid rocket booster, first place one end of the front head of the booster downward in the positioning ring 2 on the upper surface of the base 1, so that the inner ring positioning notch of the front head of the booster is circumferentially positioned through the positioning key 6, and then screw-fix the side wall of the front head of the booster to the positioning ring 2; slide the movable rod 4 to make the shaft connection end of the detection head 5 flush with the positioning block at the tail of the booster, and then flip the detection head 5 along the horizontal axis. If the positioning notch of the detection head 5 can be inserted into the positioning block at the tail of the booster, it means that the fixed phase angle requirement is met between the positioning notch processed on the inner ring of the front head of the booster and the positioning block at the tail of the booster. If the positioning notch of the detection head 5 cannot be inserted into the positioning block at the tail of the booster, the detection is unqualified.
