Description

Technical Field

[0001] This utility model relates to the field of positioning technology for drug loading machinery, specifically to a positioning bracket for radially uneven drug loading machinery. Background Technology

[0002] Commonly used mechanical positioning brackets for propellant loading are used to fix propellant loading components and ensure their accurate orientation during assembly, preventing performance degradation due to misalignment. Their main function is to achieve directional installation of radially uneven propellant loading, ensure circumferential alignment between the propellant casing and the support structure, improve assembly accuracy and safety, and are widely used in mechanical assembly fields that require highly reliable positioning.

[0003] Commonly used positioning brackets for loading machinery have simple structures and lack effective orientation recognition mechanisms. When the loading shell is inserted, there are no obvious physical limits or angle guidance. It is difficult for operators or recognition devices (machines used to capture orientation) to judge the assembly orientation, which makes it easy for the loading shell to be installed at the wrong angle. This causes radial uneven loading orientation deviation, which affects the overall performance. Moreover, it is not easy to detect after misinstallation, which poses a safety hazard and has high maintenance and rework costs.

[0004] In the field of precision blasting, the accuracy of the charge direction directly affects the energy focusing effect. Traditional assembly is prone to errors, and mechanical error-proofing structures are urgently needed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a mechanical positioning bracket that is anti-misassembly, easy to identify, simple in structure and suitable for directional assembly of radially uneven charge, so as to overcome the assembly error problem caused by the lack of directional limit and visual cues in the prior art.

[0006] To address the shortcomings of existing technologies, this utility model provides a radially uneven charge mechanical positioning bracket. The bracket body has a V-shaped notch, and the charge shell has positioning protrusions. Alignment is required for insertion; misalignment will cause interference. The false notch prevents misinstallation, and visual alignment is achieved with marking lines. It is suitable for both manual and automatic assembly. This invention solves the problems of common charge positioning brackets, which have simple structures, lack directional identification and limiting, are prone to misalignment of the charge shell, causing directional deviations, affecting performance, being difficult to detect, posing safety hazards, and incurring high rework costs.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a radially uneven drug loading mechanical positioning bracket, including a support fixing plate; and a bracket body connected to the support fixing plate. The bracket body is a hollow cylindrical structure, with a V-shaped notch and two false notches on the edge of the top end face of the bracket body. The support fixing plate and the bracket body are connected through each other, forming an axial through channel.

[0008] The propellant casing is inserted axially into the main body of the support. The outer surface of the propellant casing is provided with positioning protrusions. The depth of the false notch is less than the depth of the V-shaped notch, and the false notch cannot accommodate the positioning protrusions.

[0009] Furthermore, the V-shaped notch is a groove extending from the edge of the top end face to the outer wall. When the propellant casing is inserted, the positioning protrusion aligns with the V-shaped notch, allowing the propellant casing to continue to be pressed down until it is fully inserted.

[0010] Furthermore, the support fixing plate is provided with four mounting holes, which penetrate the support fixing plate and are distributed in the four corner areas of the support fixing plate. The mounting holes are used to insert fasteners to fix the support fixing plate to the external base.

[0011] Furthermore, alignment marking lines are provided on the outer side wall of the support body. The alignment marking lines are located on both sides of the V-shaped notch. The alignment marking lines are straight grooves engraved on the surface of the support body, and their extension lines point to the center line of the V-shaped notch.

[0012] Furthermore, the surface of the charge casing is provided with alignment arrow marks. The alignment arrow marks are located above the positioning protrusions and point to the center of the positioning protrusions. The alignment arrow marks are used in conjunction with the alignment mark lines to observe the relative angle.

[0013] Furthermore, a fixing screw is provided inside the positioning protrusion, and the positioning protrusion is connected to the outer shell of the drug loading device through the fixing screw.

[0014] Furthermore, the bottom outer edge of the support body is provided with four support feet, which are integrally formed with the support body. Three of the support feet are 15mm long and one support foot is 20mm long. The extended support feet are located at the circumferential position corresponding to the V-shaped notch.

[0015] Furthermore, when the outer casing of the explosive charge is inserted into the main body of the support from top to bottom, the positioning protrusion first contacts the edge of the V-shaped notch, and then the positioning protrusion slides down along the slope of the V-shaped notch and embeds itself, while the false notch creates physical obstruction when misaligned.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] 1. The top end face edge of the support body is provided with a V-shaped notch, and the outer surface of the charge shell is provided with positioning protrusions. The positioning protrusions can be inserted smoothly only when they are aligned with the V-shaped notch. At other angles, the positioning protrusions come into contact with the solid wall or false notch of the support body. Due to spatial interference, they cannot be pressed down. The depth of the false notch is less than that of the V-shaped notch, and there is material blocking the bottom, so the positioning protrusions cannot pass through. The V-shaped notch and the two false notches are distributed along the circumference, forming a multi-choice structure. It can be assembled in only one direction, which enhances the ability to prevent misassembly.

[0018] 2. The V-shaped notch is located at the top edge of the support body, and its opening direction is clearly visible. The alignment arrow mark on the outer shell of the charge and the alignment mark line on the support body can be directly observed from the outside. When the alignment arrow mark and the alignment mark line are on the same straight line, it indicates that the positioning protrusion is facing the V-shaped notch. This state can be judged without measuring tools and is suitable for manual assembly and automated inspection scenarios.

[0019] 3. The main body of the bracket is a hollow cylindrical structure. The V-shaped notch and the false notch can be formed in one step by CNC lathe or milling process. The notch structure is a straight line or V-shaped groove, which does not require complex curved surface processing. The support fixing plate, mounting holes, support feet, etc. are all standard mechanical structures and can be manufactured by general machining or stamping process. The overall structure has no precision fit requirements, and the tolerance is controlled within the range of conventional machining, which has good manufacturability. Attached Figure Description

[0026] This invention is applicable to the precise positioning and installation of directional explosive casings in shaped charge experiments, directional blasting experiments, or perforation projectile assembly.

[0027] 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.

[0028] Please see Figures 1-5 The radially uneven drug loading mechanical positioning bracket in this embodiment includes a support fixing plate 1; it also includes a bracket body 2 connected to the support fixing plate 1. The bracket body 2 is a hollow cylindrical structure. The top end face edge of the bracket body 2 is provided with a V-shaped notch 3 and two false notches 6. The support fixing plate 1 and the bracket body 2 are connected through each other, and the support fixing plate 1 and the bracket body 2 form an axial through channel.

[0029] In this embodiment, the top of the support body 2 is provided with a V-shaped notch 3, and the outer shell of the charge 4 has a positioning protrusion 5. It can only be inserted smoothly when the two are aligned. At other angles, it cannot be pressed down due to spatial interference. The false notch 6 is shallow and cannot pass through the positioning protrusion 5, forming a single assembly direction to enhance the ability to prevent misassembly. The opening direction is clearly visible. By observing whether the alignment arrow mark 9 on the outer shell of the charge 4 and the alignment mark line 8 on the support body 2 are on the same straight line, it can be determined whether the positioning protrusion 5 is aligned with the V-shaped notch 3. It is suitable for manual and automated assembly.

[0030] Please see Figures 1-5 In this embodiment, in order to achieve the cooperation between the V-shaped notch 3 at the top of the support body 2 and the positioning protrusion 5 on the charge housing 4, it can only be inserted when aligned. At other angles, it cannot be inserted due to interference, thus achieving one-way assembly and preventing errors. In this embodiment, the charge housing 4 is inserted into the support body 2 along the axial direction. The outer surface of the charge housing 4 is provided with positioning protrusion 5. The depth of the false notch 6 is less than the depth of the V-shaped notch 3, and the false notch 6 cannot accommodate the positioning protrusion 5.

[0031] It should be added that the false notch 6 is a groove with a similar shape to the V-shaped notch 3 but insufficient depth. Its bottom retains the material solid, which cannot allow the positioning protrusion 5 to pass through. It is only used to simulate the correct assembly opening and assist the operator in judging the direction, but it does not actually have the function of passing through.

[0032] In this embodiment, the support body 2 is used to form a hollow cylindrical structure and provides a V-shaped notch 3 and a false notch 6 at the top edge. The explosive casing 4 is used to support the positioning protrusion 5 and serves as the casing body for radially uneven explosive loading (radially uneven explosive loading refers to the uneven thickness of the explosive layer in the circumferential direction within the explosive casing, which needs to be assembled in a predetermined direction to ensure accurate high-energy release direction). The positioning protrusion 5 cooperates with the V-shaped notch 3 to achieve insertion in a unique direction. When misaligned, it interferes with the solid wall or the false notch 6 to prevent insertion. The V-shaped notch 3 provides a unique path for the positioning protrusion 5 to ensure correct assembly direction. The false notch 6 is shallow enough to prevent the positioning protrusion 5 from passing through. It is used to simulate the correct notch to create a multiple-choice illusion and enhance the ability to prevent misassembly. The alignment mark line 8 and the alignment arrow mark 9 are used for external visual judgment to determine whether they are aligned to confirm that the assembly angle is correct. The mounting hole 7 is used to insert fasteners to fix the support fixing plate 1 to the external base. The support foot 11 supports the entire bracket and keeps it stable. One of the extended support feet 11 corresponds to the direction of the V-shaped notch 3 to provide additional direction identification reference. The protrusion fixing screw 10 is used to detachably fix the positioning protrusion 5 to the charge housing 4.

[0033] It should be noted that the V-shaped notch 3 is a groove extending from the edge of the top end face to the outer wall. When the charge housing 4 is inserted, the positioning protrusion 5 aligns with the V-shaped notch 3, allowing the charge housing 4 to continue pressing down until it is fully inserted. The support fixing plate 1 has four mounting holes 7, which penetrate the support fixing plate 1 and are distributed in the four corner areas of the support fixing plate 1. The mounting holes 7 are used to insert fasteners to fix the support fixing plate 1 to the external base. The V-shaped notch 3 provides a unique alignment channel for the positioning protrusion 5. The charge housing 4 can only be smoothly inserted when the two are aligned, achieving unidirectional assembly and preventing misalignment. The charge housing 4 completes orientation identification through the cooperation of the positioning protrusion 5 and the V-shaped notch 3. The support fixing plate 1 is used to support the bracket body 2 and provide an installation base. The mounting holes 7 are used to insert fasteners to fix the support fixing plate 1 to the external base, achieving stable installation of the entire device. The four mounting holes 7 are distributed in the four corner areas of the support fixing plate 1 to ensure uniform force distribution and reliable connection.

[0034] Please see Figures 1-5 In this embodiment, the alignment arrow mark 9 and the alignment mark line 8 are exposed and visible. Alignment of the two indicates that the assembly is in place and can be visually judged without tools. The outer wall of the support body 2 in this embodiment is provided with the alignment mark line 8, which is located on both sides of the V-shaped notch 3. The alignment mark line 8 is a straight groove engraved on the surface of the support body 2, and its extension line points to the center line of the V-shaped notch 3. The surface of the charge shell 4 is provided with the alignment arrow mark 9, which is located above the positioning protrusion 5 and points to the center position of the positioning protrusion 5. The alignment arrow mark 9 is used to observe the relative angle in conjunction with the alignment mark line 8.

[0035] In this embodiment, the alignment mark line 8 is used to indicate the center direction of the V-shaped notch 3, and works with the alignment arrow mark 9 to achieve visual judgment of the assembly angle. The alignment arrow mark 9 is used to indicate the circumferential position of the positioning protrusion 5. When the two are aligned, it indicates that the charge housing 4 is in the correct assembly direction. The V-shaped notch 3 serves as the reference benchmark for the alignment mark line 8 to ensure the accuracy of the direction marking. The positioning protrusion 5 serves as the target of the alignment arrow mark 9, reflecting the key feature position on the charge housing 4. By observing whether the alignment mark line 8 and the alignment arrow mark 9 are on the same straight line, it is possible to quickly determine whether the assembly is in place without the need for measuring tools, thus improving assembly efficiency and reliability. (When the alignment arrow mark 9 and the alignment mark line 8 are visually on the same straight line, it indicates that the positioning protrusion 5 of the charge housing 4 is aligned with the V-shaped notch 3 on the support body 2, and the next insertion operation can be performed.)

[0036] It should be noted that the positioning protrusion 5 is equipped with a protrusion fixing screw 10. The positioning protrusion 5 is connected to the drug-filled outer shell 4 through the protrusion fixing screw 10. The bottom outer edge of the support body 2 is provided with four support feet 11. The support feet 11 are integrally formed with the support body 2. Three of the support feet 11 are 15mm long and one support foot 11 is 20mm long. The extended support feet 11 are located at the circumferential position corresponding to the V-shaped notch 3. When the drug-filled outer shell 4 is inserted into the support body 2 from top to bottom, the positioning protrusion 5 first contacts the edge of the V-shaped notch 3. Then the positioning protrusion 5 slides down along the slope of the V-shaped notch 3 and embeds itself. The false notch 6 creates physical obstruction when misaligned.

[0037] The working principle of the above embodiments is as follows:

[0038] In use, first, the support plate 1 is fixed to the external base through the four mounting holes 7. During installation, fasteners are passed through the mounting holes 7 and tightened to keep the support plate 1 stable. The bracket body 2 is connected to the support plate 1, and its four support feet 11 at the bottom contact the base. One of the extended support feet 11 provides a directional reference to facilitate the identification of the circumferential position of the V-shaped notch 3 (in this embodiment, only one V-shaped notch 3 is provided to define a unique assembly direction and prevent multi-directional misassembly). Then, the propellant casing 4 is aligned with the axial through-channel of the bracket body 2 from above and slowly moved downwards. At this time, the positioning protrusions 5 on the outer surface of the propellant casing 4 begin to contact the top edge of the bracket body 2. The operator can observe the alignment arrow marks. The relative position of the positioning protrusion 5 and the alignment mark line 8 is used to determine whether they are at the correct angle. If they are not aligned, the positioning protrusion 5 will contact the solid wall or the false notch 6. Since the false notch 6 is shallow and there is material obstruction at the bottom, the positioning protrusion 5 cannot pass through, generating axial resistance. This forces the operator to rotate the charge housing 4. When the alignment arrow mark 9 and the alignment mark line 8 are on the same straight line, it means that the positioning protrusion 5 is facing the V-shaped notch 3. At this time, continue to press down, and the positioning protrusion 5 will slide down along the slope of the V-shaped notch 3 and be fully embedded. The charge housing 4 will be smoothly inserted to the bottom, completing the assembly. The whole process relies on the mechanical structure to achieve unidirectional positioning, without the need for measuring tools, with strong error prevention, and is suitable for manual or automated operation.

[0039] This device is designed to solve the problem of performance failure caused by incorrect orientation during assembly of radially uneven charge. By setting a unique matching structure between the V-shaped notch 3 and the positioning protrusion 5, combined with the false notch 6 and visual alignment mark, a mechanical anti-misassembly structure is achieved, ensuring that the charge shell 4 can only be inserted in the predetermined direction, thereby improving assembly accuracy, safety and efficiency. It is used in experimental, testing or production scenarios where there are strict requirements for the charge orientation.
