Description

Technical Field

[0001] The invention belongs to the technical field of shrapnel detection, and in particular relates to a shrapnel detection machine. Background Art

[0002] Shrapnel for some special purposes, such as electronic connectors, switches, relays, etc., usually need to have good corrosion resistance to maintain good conductivity and mechanical elasticity. If the surface is oxidized or corroded, it may lead to increased contact resistance, decreased elastic performance and shortened service life. Therefore, the corrosion resistance of the shrapnel needs to be tested.

[0003] Existing shrapnel corrosion resistance testing devices mostly use salt spray test chambers. When conducting salt spray tests on shrapnel samples inside the salt spray test chamber, the samples are spread on a mesh plate. If the samples are not dispersed thoroughly enough, there is a problem of mutual obstruction. In addition, the salt spray mostly settles downward along the top of the salt spray test chamber. During the downward sedimentation process, the salt spray will adhere to the surface of the shrapnel sample for simulation experiments. However, due to the obstruction below the sample, the amount of salt spray deposited on the top of the sample is greater than the amount of salt spray deposited on the bottom of the sample, thereby affecting the test results of the sample. The salt spray test requires that the salt spray is evenly deposited on the surface of the sample to ensure the accuracy of the corrosion resistance test. However, due to the irregularity of the geometric structure of the complex-shaped shrapnel, the grooves or slits are prone to obstruction, resulting in uneven salt spray distribution. This not only affects the uniformity of corrosion, but may also accelerate corrosion in some areas due to excessive salt spray concentration, thereby affecting the reliability of the test results. In addition, the salt spray environment will accelerate the corrosion of electrical components, which also adds difficulty to the improvement of the shrapnel detection machine.

[0015] More specifically, drainage holes are evenly spaced at the bottom angle of the storage basket, an inverted V-shaped protrusion is provided between two adjacent groups of the drainage holes, and an oblique guide portion is provided between the drainage holes and the side wall of the storage basket. The drainage holes facilitate the discharge of the retained liquid at the bottom angle of the storage basket, and the inverted V-shaped protrusion and the oblique guide portion facilitate the diversion of water to the drainage holes, effectively avoiding the retention and accumulation of saline solution.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows:

[0017] 1. The adjustable loading device can adjust the front and rear tilt angles and left and right tilt angles of the loading basket respectively. By periodically tilting the loading basket back and forth, the shrapnel sample is driven to flip periodically, thereby ensuring that the salt spray is evenly deposited on the sample surface. By adjusting the left and right tilt angles of the loading basket, the shrapnel sample is exposed to the salt spray at different angles, which facilitates more uniform contact of the shrapnel sample with complex shapes with the salt spray. At the same time, when the shrapnel is tilted, the retained liquid on the surface will automatically slide down under the action of gravity.

[0018] 2. The storage basket is arranged in an inverted isosceles right triangle. When the storage basket is tilted in different directions, the shrapnel sample can be automatically flipped downward, so that different sides of the sample are exposed upward. Regardless of whether it is tilted forward or backward, when the upper right-angled side of the storage basket is adjusted to a nearly vertical state, the lower right-angled side is approximately horizontal, which can make the shrapnel sample approximately horizontal. This effectively avoids the side wall of the storage basket from blocking the upper part of the shrapnel sample and ensures uniform precipitation of salt spray.

[0019] 3. Multiple connecting rods 1 are connected to multiple first direction-adjusting components through slide 1, and connecting rod 1 is connected to multiple first direction-adjusting components, so that only one driving source is required to drive multiple first direction-adjusting components to move synchronously, so that multiple groups of storage baskets rotate synchronously around the first axis and adjust the front and rear tilt angles. At the same time, multiple connecting rods 2 are connected to multiple second direction-adjusting components through slide 2, and connecting rod 2 is connected to multiple second direction-adjusting components, so that only one driving source is required to drive multiple second direction-adjusting components to move synchronously, so that multiple groups of storage baskets rotate synchronously around the second axis and adjust the left and right tilt angles, thereby greatly reducing the number of driving sources, thereby reducing production and maintenance costs, and the drive motor is placed in an anti-corrosion and heat-insulating casing to reduce the impact of the salt spray environment on the drive motor and extend the service life of the device.

[0020] 4. The first and second direction-adjusting components cooperate with the direction-adjusting ball to drive the storage basket to rotate and tilt in multiple directions. The direction-adjusting columns and arc-shaped slide grooves on the side walls of the direction-adjusting ball cooperate with the first and second direction-adjusting components to ensure that the adjustment of the front and rear tilt angles and the adjustment of the left and right tilt angles of the storage basket are independent of each other and do not affect each other.

[0021] 5. The reciprocating swing rod is driven by the rotating rod to swing back and forth, thereby realizing reciprocating movement. The distance from the swing axis to the clamping axis is adjusted to adjust the sliding distance of the reciprocating slide rod, and then the left and right tilt angles of the storage basket are adjusted to meet different detection requirements.

[0022] 6. The shrapnel specimens can be placed independently through the storage basket to avoid obstruction. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] See Figures 1-13 A controller 64 is provided on the outside of the salt spray test chamber body 1, and the controller 64 is electrically connected to the drive motor 48 and the electric push rod 52 of the adjustable reciprocating motor 1 41 and the drive motor 48 and the electric push rod 52 of the adjustable reciprocating motor 2 44 respectively.

[0052] When in use, the salt spray test box body 1 is debugged with water and sodium chloride solution is added, and then the shrapnel samples are placed in the storage baskets 15 one by one, and each storage basket 15 is placed with a shrapnel sample, and the shrapnel sample is kept in contact with one side of the storage basket 15. After the placement is completed, the box cover 3 is opened, and the sample rack 9 is placed on the two placement racks 6. The placement cross bar 10 is inserted into the placement slot 18, and the first clamping rod 37 is inserted into the clamping slot 1 42, and the second clamping rod 38 is inserted into the clamping slot 2 46. The placement slot 18 and the inner wall of the detection chamber 2 limit the horizontal movement of the placement cross bar 10, so that it cannot move and can only move up and down. During the specific operation, the sample rack 9 can also be clamped into the placement rack 6 first, and then the shrapnel sample is placed in the storage basket 15. After the sample is placed After completion, start the salt spray test chamber body 1 to start the test and conduct corrosion resistance testing. In the initial state, the rotating rod 49 of the adjustable reciprocating motor 41 is set horizontally, the support column 14 and the storage basket 15 are tilted forward or backward, the upper right-angled side of the storage basket 15 is slightly tilted to one side, and the lower right-angled side of the storage basket 15 is slightly tilted downward and is approximately horizontal. The shrapnel sample is attached to the lower right-angled side of the storage basket 15 under the action of gravity. At this time, the shrapnel sample is also approximately horizontal, and the salt spray settles above the shrapnel sample. The controller 64 controls the snap-on drive 17 to trigger the action at a fixed time interval T1 and controls the snap-on drive 28 to trigger the action at a fixed time interval T2. Each time the snap-on drive 17 is actuated, the controller 64 controls the adjustable The driving motor 48 of the reciprocating motor 41 rotates 180°, and the driving motor 48 rotates 180°, driving the rotating rod 49 to rotate 180° around the output shaft of the driving motor 48. The rotating rod 49 drives the bottom end of the reciprocating swing rod 50 to rotate from one side of the support plate 54 to the other side of the support plate 54 through the dial shaft 58 and the swing slide hole 57. The reciprocating swing rod 50 drives the reciprocating slide rod 51 from one side of the reciprocating slide hole 59 to the other side of the reciprocating slide hole 59 through the push slide hole 55 and the card shaft 60. The reciprocating slide rod 51 drives the slide plate 39 to slide forward (backward). The slide plate 39 drives the connecting rod 34 to slide forward (backward) through the first card rod 37. The connecting rod 34 drives multiple groups of adjustment slide rods 25 to slide forward (backward). The adjustment slide rod 25 is driven by the rack 2 7 drives the steering gear 24 to rotate, and the steering gear 24 drives the rotating frame 22 to rotate around the first axis through the rotating shaft 23. The rotating frame 22 drives the steering ball 13 to rotate around the first axis through the steering column 19, and the steering ball 13 drives the storage basket 15 to rotate and tilt to the other side. The storage basket 15 rotates at an angle slightly greater than the angle of the storage basket. In this embodiment, the storage basket 15 rotates at an angle slightly greater than 90 degrees each time, so that the storage basket 15 is slightly tilted to one side at the upper right-angled side and slightly tilted downward at the lower right-angled side and is approximately horizontal. The shrapnel sample is also automatically flipped during the rotation of the storage basket 15 so that the bottom edge of the shrapnel sample is exposed to facilitate salt spray deposition. The driving motor 48 of the adjustable reciprocating motor 41 periodically rotates 180 degrees.The storage basket 15 is driven to tilt back and forth periodically, so that the two sides of the shrapnel sample are alternately facing upward, thereby ensuring that the salt spray is evenly deposited on the sample surface. Each time the snap-on drive 28 moves, the controller 64 controls the drive motor 48 of the adjustable reciprocating motor 244 to rotate 90°. The snap-on drive 28 moves four times per cycle, driving the rotating rod 49 of the adjustable reciprocating motor 244 to rotate one circle. The rotating rod 49 drives the bottom end of the reciprocating swing rod 50 to swing back and forth once through the dial shaft 58 and the swing slide hole 57, so that the reciprocating swing rod 50 drives the reciprocating slide rod 51 to slide back and forth once through the push slide hole 55 and the card shaft 60. The reciprocating slide rod 51 of the adjustable reciprocating motor 244 drives the slide plate 2 43 to slide back and forth once. The slide plate 2 43 drives the connecting rod 2 35 to slide back and forth once through the second card rod 38. The connecting rod 2 35 drives multiple groups of directional adjustment slides through the directional adjustment slide rod 2 31 The second rod 31 slides back and forth left and right, and the second adjustment slide rod 31 drives the second adjustment gear 30 to rotate through the second rack 33. The second adjustment gear 30 drives the second rotating frame 28 to rotate around the second axis through the second rotating shaft 29. The second rotating frame 28 drives the adjustment ball 13 to rotate back and forth once around the adjustment column 19 through the adjustment slide shaft 21. The adjustment ball 13 drives the storage basket 15 to rotate back and forth once around the second axis. During this process, the storage basket 15 changes from vertical to left tilted to vertical to right tilted to vertical in the X-axis direction. The arc-shaped slide groove 20 can ensure that the adjustment of the front and rear tilt angles and the adjustment of the left and right tilt angles of the storage basket 15 are independent of each other and do not affect each other. By tilting the storage basket 15 left and right, the shrapnel specimens are exposed to the salt spray at different angles, which facilitates more uniform contact of shrapnel specimens with complex shapes with the salt spray. At the same time, when the shrapnel is tilted, the retained liquid on the surface will automatically slide down under the action of gravity.

[0053] In this embodiment, in one cycle of the engaging drive 1 7, the engaging drive 2 8 can be set to periodically intermittently act four times. During this cycle, the storage basket 15 remains in a forward or backward tilted state, and the storage basket 15 changes in the X-axis direction from vertical-left tilted-vertical-right tilted-vertical, so that the salt mist deposition is more uniform.

[0054] During use, the controller 64 can be used to control the electric push rod 52 to extend and retract, thereby driving the adjustment slide 53 to move up and down in the drive chamber, adjusting the distance between the swing shaft 56 and the card shaft 60, and thus adjusting the sliding distance of the reciprocating slide 51. The smaller the distance between the swing shaft 56 and the card shaft 60, the smaller the sliding distance of the reciprocating slide 51, the smaller the sliding distance of the slide 1 39 (slide 2 43), the smaller the sliding distance of the rack 1 27 (rack 2 33), the smaller the rotation angle of the adjustment ball 13 driven by the adjustment gear 1 24 (adjustment gear 2 30), and the smaller the inclination angle of the storage basket 15. Conversely, the inclination angle of the storage basket 15 increases.
