[0001] The utility model relates to the technical field of C-shaped instrument joint detection, in particular to a C-shaped instrument joint electrolytic surface defect detection device. Background Art

[0002] C-shaped instrument connector is a component widely used in equipment such as pressure gauges, vacuum gauges and temperature instruments. Generally, surface defects can be found through the electrolytic process by electrolytic surface defect detection devices to improve product quality control and reliability.

[0003] When the C-shaped instrument connector is inspected by an electrolytic detection device, the electrolyte is mostly cooled naturally, and it is difficult to cool the electrolyte well. The cooling effect is poor. When the C-shaped instrument connector is placed in the electrolyte for electrolytic reaction once or multiple times, the electrolysis will generate heat, making the electrolyte high temperature, causing the electrolyte to evaporate and decompose, affecting the conductivity and reaction effect of the electrolyte. In addition, the high-temperature electrolyte near the C-shaped instrument connector is prone to violent reaction to the C-shaped instrument connector, causing strong corrosion on the surface of the C-shaped instrument connector and causing damage to it.

[0018] In an optional embodiment: the moving assembly includes an assembly box 5, a reduction motor 54 and a placement frame 21 fixedly connected to the outside of the spiral cooling tube 2, the C-shaped instrument connector can be connected to the placement frame 21 for detection, a movable frame 52 is arranged inside the assembly box 5, a U-shaped movable frame 51 is fixedly connected between the movable frame 52 and the spiral cooling tube 2, the top and bottom of the inner wall of the U-shaped movable frame 51 are provided with racks 53, an incomplete gear 55 used in conjunction is arranged between the two racks 53, and the output end of the reduction motor 54 is fixedly connected to the incomplete gear 55. At the center of one side, specifically, the incomplete gear 55 can mesh with the rack 53, the reduction motor 54 is fixedly installed inside the assembly box 5, and a through hole is set on the top of the assembly box 5. One side of the U-shaped movable frame 51 passes through the through hole to facilitate the movement of the U-shaped movable frame 51. When the reduction motor 54 is rotated, the incomplete gear 55 will be driven to rotate, and the tooth block on the incomplete gear 55 will repeatedly pass through two gear pairs, so that the movable frame 52 drives the placement frame 21 to move horizontally repeatedly. By controlling the rotation speed of the reduction motor 54, the movement amplitude of the placement frame 21 can be controlled. Further, the spiral cooling tube 2 and the placement frame 21 are made of tantalum, which has good thermal conductivity and corrosion resistance, and avoids being affected by the electrolyte.

[0019] In an optional embodiment: the interior of the assembly box 5 is fixedly connected with a guide rod 56 parallel to the length direction of the movable frame 52, and one side of the movable frame 52 is slidably sleeved on the outside of the guide rod 56, so that the movable frame 52 can move stably through the cooperation of the guide rod 56, and a slide groove 10 is opened at the bottom of the inner wall of the box body 1, and the placement frame 21 is slidably connected to the slide groove 10 through the slider 20, and the placement frame 21 can move more stably through the cooperation of the slide groove 10 and the slider 20.

The controller obtains the signals of the voltage sensor and the current sensor through this connection, and converts them into digital signals for processing and analysis. The controller analyzes the current and voltage changes in the electrolyte according to the signals of the current sensor and the voltage sensor to detect surface defects of the C-shaped instrument connector. At the same time, the controller converts the detection results into readable outputs, such as signals or digital signals on the display screen, for users to observe.

When the electrolytic component is used to test it, the coolant is continuously passed through the spiral cooling tube 2, and the controller controls the moving component to drive the spiral cooling tube 2, the placement frame 21 and the C-shaped instrument connector to move horizontally repeatedly in the box 1. The spiral cooling tube 2 is fully in contact with the electrolyte, and the coolant in the spiral cooling tube 2 effectively takes away the heat of the electrolyte, allowing the electrolyte to cool down quickly, avoiding the electrolyte from generating high temperature during multiple electrolytic tests on the C-shaped instrument connector, thereby effectively avoiding the evaporation and decomposition of the electrolyte and corrosion of the surface of the C-shaped instrument connector.

[0023] The temperature of the electrolyte is detected by the temperature sensor 7, and the low temperature threshold of the temperature sensor 7 is preset by the controller. When the threshold is reached, the control of the mobile component is stopped, and the alarm is activated to remind the user to close the circulation of the coolant in time to prevent the electrolyte temperature from being too low.
