Description

Technical Field

[0001] The utility model belongs to the technical field of initiators, and particularly relates to a safety assembly mechanism for an initiator release device. Background Technique

[0002] The release device belongs to an initiator working device, and its function is to release the lock on the actuator. Its structure is as Figure 4 shown. Before the release device works, a reliable connection to the actuator is achieved; after receiving the firing signal, the piston of the release device retracts to release the lock of the actuator. Similar products also include: pin pullers, pushers, etc.

[0003] During the assembly process of the release device, there are situations where the appearance of the product is damaged and accidental activation may occur.

[0004] A typical assembly process of the release device is as follows: directly clamp the release device body onto the vise → apply a large clamping force on the vise to reliably fix the device body → apply torque on the electric detonator to complete the assembly of the electric detonator → remove the release device.

[0005] This assembly process has the following problems:

[0006] First, the vise directly clamps the release device body. Since the jaws of the vise are relatively rough, it is very easy to clamp and damage the release device body, resulting in damaged appearance.

[0007] Second, since each product needs to be clamped on the vise for the processes of repeated clamping, fixing, torque application, and disassembly, the process is relatively cumbersome and the assembly efficiency is low.

[0008] Third, since the initiator contains energetic materials, under the action of external stimuli, including electromagnetic environment, mechanical environments such as extrusion, dropping, and bumping, and other stress environments, the product may be accidentally activated. Once accidentally activated, the release device will generate a certain impact, which will cause certain harm to the operator.

[0009] Therefore, it is necessary to improve the assembly process, design a safety assembly mechanism, change the direct clamping method to indirect clamping to protect the appearance of the product. At the same time, it can improve the assembly efficiency and has a certain protective effect on the operator. Content of the Utility Model

[0027] Embodiment 1

[0028] A safety assembly mechanism for an explosive device release device, comprising an assembly base 2 that cooperates with the release device 1; the assembly base 2 is a cuboid block structure, and the assembly base 2 is provided with a release device flange mounting groove 3, a body mounting groove 4, and a piston mounting groove 5;

[0029] The release device 1 includes a cylindrical body, a square base at the bottom of the body, and flanges and a cylindrical structure are respectively provided at the front and rear of the square base.

[0030] The piston mounting groove 5 is a strip-shaped groove that extends from the top to the bottom on one side of the assembly base 2, so that the side where the piston mounting groove 5 is located is concave-shaped, and the width of the piston mounting groove 5 is greater than the piston diameter of the release device 1; the piston mounting groove 5 is located in the center of the side where it is located; behind the plane where the piston mounting groove 5 is located is a rectangular plate-shaped flange mounting groove 3, and the depth of the flange mounting groove 3 is greater than that of the piston mounting groove 5, the length is the length of the side where the piston mounting groove 5 is located, and the width is the thickness of the flange of the release device 1. The flange mounting groove 3 is used to limit the release device flange; the body mounting groove 4 is located behind the flange mounting groove 3, the width of the body mounting groove 4 is the widest part of the base of the release device 1, and the depth of the body mounting groove 4 is greater than that of the piston mounting groove 5 and less than the height of the release device 1; the body mounting groove 4 is used to limit the body of the release device 1 so that it does not undergo relative displacement when subjected to an external force, ensuring the smooth progress of the installation.

[0031] The material of the assembly base 2 is alloy tool steel Cr12.

[0032] During use, the assembly base 2 confines the release device 1 inside the assembly mechanism. Place the assembly base 2 on a vise, and at Figure 3The position indicated by the middle arrow is firmly clamped. The base of the release device 1 includes a square seat and a columnar structure connected to the rear of the square seat, wherein the width of the square seat is greater than the diameter of the columnar structure; the main body mounting groove 4 is interference fit with the square seat. The flange mounting groove 3 is interference fit with the flange of the release device 1 to clamp the front and rear end faces of the flange. When the release device 1 is subjected to a large assembly torque, the deformation of the flange is small due to the large contact area and tight fit.

[0033] The utility model transfers the vise clamping position from the release device body to the assembly base 2 to avoid clamping the release device body. The assembly base is designed with a spatial structure that is completely and tightly combined with the outer dimensions of the release device body, so that the release device body can be directly placed in the assembly base. When applying torque for assembly, the relative movement of the release device body is directly constrained and limited. No corresponding external fixing structure is required. The structure is very simple and easy to operate, which greatly improves the assembly efficiency. When applying torque, since the release device body and the detonator are constrained in the assembly body, even if the product acts unexpectedly, it can effectively protect personnel.
