Description

Technical Field

[0001] This utility model belongs to the field of clamping fixture technology, specifically a clamping fixture for testing missile fuses. Background Technology

[0002] In the process of missile research and development and maintenance, the performance testing of missile fuzes is a crucial step, as the test results directly affect the missile's combat effectiveness and operational safety. As one of the core components of a missile, the fuze has a precise structure and extremely high requirements for external forces and positioning accuracy. During testing, it must be strictly clamped and fixed to avoid test data deviations due to unstable clamping, or even safety hazards such as false triggering of the fuze.

[0003] In the existing technology, universal clamps cannot adapt to the structural differences of different missile fuses, cannot adapt to missile fuses of different sizes, and cannot effectively fix the missile fuses, resulting in unstable clamping and deviations in test data.

[0004] Therefore, this utility model provides a clamping fixture for testing missile fuses. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problems that general-purpose fixtures cannot adapt to the structural differences of different missile fuses, cannot adapt to missile fuses of different sizes, and cannot effectively fix missile fuses, resulting in unstable clamping and deviations in test data.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A clamping fixture for testing a missile fuze, comprising a base plate, a pair of fixed posts fixedly connected to the bottom of the base plate, and a clamping mechanism provided at the top of the base plate, the clamping mechanism comprising:

[0007] The clamping assembly has a set of sliding slots on the base plate, a sliding block is slidably connected in the sliding slot, a rotating rod is rotatably connected to the sliding block through a rotating hole, a clamping block is fixed to the top of the rotating rod, and a pair of clamping blocks are symmetrically arranged. A rubber pad is provided on the inner side of the clamping block, and a moving assembly for moving a set of sliding blocks is provided at the bottom of the base plate.

[0008] An adjustment component, located at the bottom of the base plate, is used to drive a set of clamping blocks to rotate.

[0009] Preferably, the moving component includes an L-shaped plate fixed to the bottom of the base plate, a motor fixed to the top of the L-shaped plate laterally, and a drive rod provided at the output end of the motor.

[0010] Preferably, an adjusting rod is fixedly connected to the top of the driving rod, and both ends of the top of the adjusting rod are rotatably connected to connecting rods via a first rotating shaft.

[0011] Preferably, the top of the connecting rod away from the adjusting rod is rotatably connected to a rectangular block via a second rotating shaft, and the top of the rectangular block is fixed to the bottom of the rotating rod.

[0012] Preferably, the adjustment assembly includes a pair of fixing blocks fixed to the bottom of the base plate, an electric actuator fixed to the side wall of the fixing block, and a connecting block fixed to the telescopic end of the electric actuator.

[0013] Preferably, a rectangular rod is rotatably connected to the top of the connecting block via a pair of third rotating shafts, and a rectangular through groove is provided on the rectangular block, with the rectangular rod slidably connected within the rectangular through groove.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The clamping fixture for missile fuze testing described in this utility model uses a motor-driven adjusting rod and connecting rod to drive a sliding block, thereby continuously adjusting the spacing between the clamping blocks. This allows it to adapt to missile fuzes of different specifications within a certain diameter range without requiring fixture replacement, significantly reducing the investment cost of testing equipment. Compared to traditional single-size fixtures, the equipment utilization rate is greatly improved. This solves the problem in the prior art where general-purpose fixtures cannot adapt to the structural differences of different missile fuze models, cannot adapt to missile fuzes of different sizes, and cannot effectively fix the missile fuze, resulting in unstable clamping and deviations in test data.

[0016] 2. The clamping fixture for missile fuze testing described in this utility model allows the operator to control the extension and retraction of the electric push rods on both sides according to the curvature (such as conical or arc-shaped) of the outer wall of the missile fuze: if the inclination angle of one side of the outer wall of the fuze is large, the electric push rod on the corresponding side can be extended, causing the clamping block to rotate in the direction of the fuze until the rubber pad is completely in contact with the outer wall of the fuze, achieving "surface contact" clamping rather than "point contact" or "line contact", thereby improving the stability, safety and adaptability of the clamping.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown, a clamping fixture for testing a missile fuse according to an embodiment of the present invention includes a base plate 1, a pair of fixed posts 17 fixed to the bottom of the base plate 1, and a clamping mechanism on the top of the base plate 1. The clamping mechanism includes: a clamping assembly, a set of sliding grooves 2 opened on the base plate 1, a sliding block 3 slidably connected in the sliding grooves 2, a rotating rod 4 rotatably connected to the sliding block 3 through a rotating hole, a clamping block 5 fixed to the top of the rotating rod 4, and a pair of clamping blocks 5 symmetrically arranged. A rubber pad 18 is provided on the inner side of the clamping block 5. A moving assembly for moving a set of sliding blocks 3 is provided at the bottom of the base plate 1; and an adjusting assembly provided at the bottom of the base plate 1 for rotating a set of clamping blocks 5.

[0025] The moving component includes an L-shaped plate 6 fixed to the bottom of the base plate 1, a motor 7 fixed to the top of the L-shaped plate 6 laterally, and a drive rod 8 provided at the output end of the motor 7.

[0026] An adjusting rod 9 is fixedly connected to the top of the drive rod 8, and both ends of the top of the adjusting rod 9 are rotatably connected to the connecting rod 10 through the first rotating shaft.

[0027] The top of the connecting rod 10, away from the adjusting rod 9, is rotatably connected to a rectangular block 11 via a second rotating shaft. The top of the rectangular block 11 is fixed to the bottom of the rotating rod 4.

[0028] During operation, the motor 7 drives the adjusting rod 9 and the connecting rod 10, which in turn drives the sliding block 3 to continuously adjust the spacing of the clamping block 5. This allows for the adaptation of missile fuses of different specifications within a certain diameter range, eliminating the need to change tooling and significantly reducing the investment cost of testing equipment. Compared with traditional single-size tooling, the equipment utilization rate is greatly improved. This solves the problem in existing technologies where general-purpose fixtures cannot adapt to the structural differences of different missile fuse models, cannot adapt to missile fuses of different sizes, and cannot effectively fix the missile fuse, resulting in unstable clamping and deviations in test data. The rubber pad 18 (preferably nitrile rubber with a Shore hardness of 50-60) on the inner side of the clamping block 5 has good elasticity and wear resistance. During clamping, it can absorb the clamping force through its own deformation, avoiding rigid contact damage to the fuse shell. At the same time, the anti-slip properties of the rubber pad 18 can prevent the fuse from sliding during testing, ensuring clamping stability.

[0029] The adjustment assembly includes a pair of fixed blocks 12 fixed to the bottom of the base plate 1, an electric push rod 13 fixed to the side wall of the fixed block 12, and a connecting block 14 fixed to the telescopic end of the electric push rod 13.

[0030] A rectangular rod 15 is rotatably connected to the top of the connecting block 14 via a pair of third rotating shafts. A rectangular through groove 16 is provided on the rectangular block 11, and the rectangular rod 15 is slidably connected in the rectangular through groove 16.

[0031] During operation, the operator can control the extension and retraction of the electric actuators 13 on both sides according to the curvature (such as conical or arc-shaped) of the outer wall of the missile fuze: if the outer wall of one side of the fuze has a large tilt angle, the electric actuator 13 on the corresponding side can be extended, so that the clamping block 5 rotates in the direction of the fuze until the rubber pad 18 is completely in contact with the outer wall of the fuze, so as to achieve "surface contact" clamping, rather than "point contact" or "line contact", thereby improving the stability, safety and adaptability of clamping.

[0032] Working principle: The motor 7 on the L-shaped plate 6 at the bottom of the base plate 1 is started. The output of the motor 7 drives the drive rod 8 to rotate, which in turn drives the adjusting rod 9 fixed to the top of the drive rod 8 to rotate synchronously. Since the two ends of the top of the adjusting rod 9 are rotatably connected to the connecting rod 10 through the first rotating shaft, and the end of the connecting rod 10 away from the adjusting rod 9 is rotatably connected to the rectangular block 11 through the second rotating shaft (the top of the rectangular block 11 is fixed to the bottom of the rotating rod 4), the rotation of the adjusting rod 9 will generate a lateral thrust or pull force. This force is transmitted to the rectangular block 11 through the connecting rod 10, driving the bottom of the rotating rod 4... The rectangular block 11 moves laterally, while the rotating rod 4 and the sliding block 3 are rotatably connected through the rotating hole, and the sliding block 3 slides with the sliding groove 2 of the base plate 1. Therefore, the lateral movement of the rectangular block 11 will drive the sliding block 3 to move towards or away from each other along the sliding groove 2. When facing a missile fuze with a larger diameter, the sliding block 3 moves away from each other, increasing the distance between a pair of clamping blocks 5. When facing a fuze with a smaller diameter, the sliding block 3 moves towards each other, reducing the distance between the clamping blocks 5, until the rubber pad 18 on the inner side of the clamping block 5 is aligned with the preset clamping point on the outer wall of the fuze, thus completing the lateral position adaptation.

[0033] After the moving component completes the lateral position adaptation, the electric push rod 13 on the bottom fixing block 12 of the base plate 1 is activated. The extension end of the electric push rod 13 drives the connecting block 14 to move laterally. The top of the connecting block 14 is rotatably connected to the rectangular rod 15 through the third rotating shaft, and the rectangular rod 15 is slidably connected in the rectangular through groove 16 of the rectangular block 11. The extension and retraction of the electric push rod 13 will drive the rectangular rod 15 to move through the connecting block 14. When the rectangular rod 15 slides in the rectangular through groove 16, it will generate a lateral force on the rectangular block 11. Since the rectangular block 11 is fixed to the bottom of the rotating rod 4 and the rotating rod 4 is rotatably connected to the sliding block 3, this lateral force will drive the rotating rod 4 to rotate around the axis of the rotating hole, thereby driving the clamping block 5 at the top to rotate synchronously to adapt to the outer wall of the shell with different curvatures.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
