Description

Technical Field

[0001] The present invention relates to the technical field of warhead electrical performance detection, in particular to a warhead electrical performance detection probe adjustment and fixing device. Background Art

[0002] Electrical performance testing, a process inspection for electronic products in industrial automation testing, ensures product quality and yield, avoiding returns and scrap due to substandard electrical performance. Spring test probes, commonly used in electrical performance testing, come in a wide variety of models, offering varying needle shapes, thicknesses, lengths, and clamping forces. Engineers select the appropriate probe tip model for electrical performance testing based on the specific testing environment and process requirements.

[0003] The electrical performance test of the warhead belongs to the electrical performance test of energetic materials. The testing station is dangerous and requires a design for human-machine isolation operation.

[0004] The current solution for testing the electrical performance of the warhead is manual testing, and the manual testing station is located in an independent explosion-proof room. Usually, the tester transports two warheads to the electrical performance testing room via a transfer cart, places one warhead on the testing table, and uses a V-shaped block to support it horizontally, with the head facing the explosion venting surface of the explosion-proof room. The tester connects two test leads to the test meter, short-circuits the tips of the two test leads, and zeroes the test meter. Afterwards, the tester performs electrical performance tests on each test point of the warhead in accordance with the test process sequence. Specifically, the tester adjusts the test meter to the corresponding gear, places the tip of the test lead against the test point, applies a little force with the hand, keeps it stable, and reads the meter.

[0005] However, during the current manual testing of warhead electrical performance, the test leads are placed against the test point, requiring the tester to maintain a steady force to ensure a reliable connection between the test leads and the test point. This pressure from the test lead tip can cause the test instrument reading to fluctuate, resulting in unstable test values. Summary of the Invention

[0065] The specific structure and usage method of the warhead electrical performance detection probe adjustment and fixing device provided in this application are introduced in detail below.

[0066] The present invention mainly comprises a warhead head electrical performance detection tool 1, a shoulder electrical performance detection tool 2 and a main charge shell electrical performance detection tool 3.

The opposite side of the opening of the clamp 101 is a movable mechanism, which specifically refers to a guiding part sliding with a first probe mounting seat 106 by a first main guide rod 104 and a first auxiliary guide rod 105. The two guide rods are installed outside the clamp 101, and the first probe mounting seat 106 is nested with two oil-free bushings 109 to form a sliding pair with the two guide rods. The first main guide rod 104 is longer than the first auxiliary guide rod 105 by a threaded rod, and the first main guide rod 104 is provided with a first height adjustment rotating rod 107 at the end of the threaded rod.

The two lower oblique sides of the first base 201 and the two upper oblique sides of the first upper buckle block 203 are designed with step structures of the same height to fit the shoulder structure of the warhead and limit its axial movement space. Each of the 2 oblique sides of the first base 201 has a through slot, and the first limit block 202 can slide up and down in the through slot. A butterfly screw is connected to the outside to fix the position of the first limit block 202 in the through slot. The first limit block 202 can be extended or retracted to accommodate different warheads with different axial limit distances. The first base 201 and the first upper buckle block 203 are connected on one side by a first hinge pin 204. The first upper buckle block 203 can be rotated open around the first hinge pin 204 to facilitate the insertion or removal of the warhead. On the other side of the first base 201 and the first upper buckle block 203, a first clamping screw 206 is mounted on the side of the first base 201 via a first pin 205. The first clamping screw 206 can be rotated and flipped upward around the first pin 205. A first butterfly nut 207 is mounted on the first clamping screw 206 to facilitate locking the first upper buckle block 203. The top edge of the first upper buckle block 203 is connected to the second probe mounting base 208. The second probe mounting base 208 is connected to a second main guide rod 213 and a second secondary guide rod 214. The upper guide plate 209 is nested in an oil-free bushing, forming a sliding pair with the two guide rods. A second height adjustment lever 215, attached to the second main guide rod 213, adjusts the position of the upper guide plate 209 on the two guide rods. Each guide rod has a compression spring to maintain a closed force. The lower portion of the upper guide plate 209 has a waist-shaped hole with a beveled feature and two through holes on either side. The upper portion of the lower guide plate 210 has a similar waist-shaped hole with inclined features, with screw sleeves nested on both sides. The ball seat 211 is spherical in shape with a through hole, the axis of which passes through the center of the ball. The through hole of the ball seat 211 is installed with a shoulder detection probe 212 needle. The probe passes through the waist-shaped holes of the upper guide plate 209 and the lower guide plate 210 respectively. Four sets of ball seats 211 with probes are arranged side by side in the waist-shaped holes. The ball seats 211 are formed by the rhombus formed by two pairs of upper and lower inclined features to form a ball pair. The shoulder detection probe 212 can rotate around the center of the ball seat 211. The ball seat 211 can also slide horizontally within the rhombus space formed by the inclined features, achieving a certain degree of fine-tuning of the angle and position of the shoulder detection probe 212 in a small space. The butterfly screws on both sides of the upper guide plate 209 pass through the through holes and connect to the lower guide plate 210. Tightening the butterfly screws on both sides fixes the ball seat 211 with probes.

[0073] To improve the accuracy of electrical performance testing, the first base 201 and first upper buckle block 203 are made of polyformaldehyde, the second probe mounting base 208 is made of epoxy glass cloth paper-based material, and the second height adjustment rod 215 is also made of polyformaldehyde. A threaded sleeve is embedded in the second height adjustment rod 215, facilitating frequent tightening and loosening of the rod, thereby extending the overall service life of the tooling.

[0074] As can be seen, the warhead shoulder electrical performance testing tool 2 adopts an octagonal clamping design, with the base occupying the lower five sides and the upper buckle block occupying the upper three sides. The upper buckle block is connected to the base via a hinge pin, which facilitates the opening and closing of the upper buckle block, allowing the warhead to be inserted and removed. The upper buckle block uses a butterfly nut to quickly lock and release the warhead. Boss structures are designed on the oblique sides of the base and the upper buckle block to limit the axial movement of the warhead. The upper guide pressure plate 209 and the lower guide pressure plate 210 are designed with waist-shaped holes with inclined surface features. Four sets of ball seats 211 with detection probes installed pass through the upper and lower waist-shaped holes. The ball seats 211 form a ball pair between the prisms formed by the upper and lower inclined surface features, allowing the detection probes to be adjusted in angle. The ball seats 211 can also slide horizontally on the inclined surface to adjust the relative position of the detection probes. The upper guide plate 209 and the lower guide plate are connected by butterfly screws. Tightening the butterfly screws can lock the angle and position of the fixed ball seat 211, thereby fixing the direction and position of the detection probe.

[0075] like Figure 4 As shown, the main charge shell electrical performance detection tool 3 is mainly composed of a second base 301, a second upper block 302, a second hinge pin, a second pin 303, a second clamping screw 304, a second butterfly nut 305, a third probe mounting seat 306, a compression spring, a main charge shell detection probe 307, a guide rod 308 and a third height adjustment rotary rod 309.

[0076] Specifically, the second base 301 and the second upper buckle block 302 enclose an inner opening that is octagonal. The two lower oblique sides of the second base 301 and the two upper oblique sides of the second upper buckle block 302 are designed with step structures of the same height to fit the shoulder structure of the warhead and limit its axial movement space. The second base 301 and the second upper buckle block 302 are connected on one side by a second hinge pin. The second upper buckle block 302 can be rotated around the second hinge pin to open, making it easier to put the warhead in or out. On the other side of the second base 301 and the second upper buckle block 302, a second clamping screw 304 is installed on the side of the second base 301 through a second pin 303. The second clamping screw 304 can be rotated around the second pin 303 and flipped up. There is a second butterfly nut 305 on the second clamping screw 304 to facilitate locking the second upper buckle block 302. The second upper buckle block 302 has a notch on the top edge, within which two guide rods are connected. The third probe mount 306 is nested with an oil-free bushing, forming a sliding pair with the guide rods. The side of the third probe mount 306 forms a sliding fit with the sidewall of the notch on the top edge of the second upper buckle block 302, limiting the rotational freedom of the third probe mount 306. Each threaded end of the two guide rods has a third height adjustment rod 309. Rotating the third height adjustment rod 309 adjusts the position of the third probe mount 306 on the guide rod 308. Each of the two guide rods 308 has a compression spring that acts as a force-closing component for adjustment. A main charge shell detection probe is mounted at the end of the third probe mount 306.

[0077] To improve the accuracy of electrical performance testing, the second base 301 and second upper buckle 302 are made of polyoxymethylene, the third probe mounting base 306 is made of epoxy glass cloth paper-based material, and the third height adjustment rod 309 is also made of polyoxymethylene. A threaded sleeve b is inserted into the third height adjustment rod 309, facilitating frequent tightening and loosening of the rod 309 and extending the overall service life of the tooling.

[0078] As can be seen, the warhead main charge shell electrical performance test fixture 3, like the warhead shoulder electrical performance test fixture 2, adopts an octagonal clamping design. The boss structure designed on the base and the oblique edge of the upper buckle block, together with the boss structure on the warhead electrical performance test fixture, constitutes a structural form that limits the axial movement of the warhead. There are two sets of electrical performance test probes on the upper buckle block of the warhead main charge shell electrical performance test fixture 3. Specifically, the two sets of electrical performance test probes are each guided up and down by a guide rod. The notch structure on the upper mouth block limits the rotation of the probe mounting seat around the guide rod. The height adjustment lever on the upper part of the guide rod and the compression spring on the lower part control the up and down position of the probe mounting seat.

[0079] The warhead electrical performance detection probe adjustment and fixing device provided in the embodiment of the present application is used as follows: Figure 5 As shown, the shoulder electrical performance test tool 2 and the main charge shell electrical performance test tool 3 can be installed on the tray 4. The tray 4 is provided with an electrical inspection box 5 and a quick connection plate 6 that are electrically connected to each other. The head electrical performance test tool 1 can be connected to the mounting bracket of the quick connection plate 6. After the warhead is fixed, the probes of each tool are brought into contact with the detection points on the warhead, and then the wiring terminals of each probe are connected to the spring aging clips on the quick connection plate 6, so that the probes are electrically connected to the quick connection plate 6 and the electrical inspection box 5. Transport the tray 4 and all the components on it to the electrical inspection tool. After the electrical inspection box 5 is connected to the electrical inspection mother box at the electrical inspection tool, the electrical performance test of the warhead can be carried out.

[0080] In summary, the warhead electrical performance detection probe adjustment and fixing device provided by the present application allows testers to adjust and fix the warhead probe through the device, ensuring that the test probe can effectively and stably abut against the warhead test point during the electrical performance detection process, avoiding the fluctuation of electrical performance detection data caused by unstable test point abutment due to human control. The shoulder electrical performance detection tooling and the main charge shell electrical performance detection tooling can restrain the axial movement of the warhead through the step features designed on the bevel. The shoulder electrical performance detection tooling and the main charge shell electrical performance detection tooling can keep the warhead stable during transportation through the upper buckle block that can be flipped open and buckled, and the butterfly nut lock design that can be quickly pressed, locked and loosened. The detection probe is stably abutted. By adjusting the protrusion and retraction of the shoulder electrical performance detection tooling limit block, the axial limit of warheads of different lengths can be compatible.
