Technical Field
[0001] This utility model relates to the field of contact detection equipment technology, specifically a contact defect detection device with positioning and fixing detection function. Background Technology
[0002] As a key component in electrical equipment used to connect and disconnect circuits, the performance of contacts directly affects the safety and reliability of electrical systems. During the manufacturing and long-term use of contacts, various defects may occur, such as surface wear, cracks, deformation, and deterioration of electrical performance. If these defects are not detected in time, they may cause serious electrical faults and even endanger personnel lives and equipment safety.
[0003] However, existing contact defect detection devices still have certain problems:
[0004] An existing device for detecting moving contacts, such as the one described in application number CN201420228273.7, aims to provide a simple and convenient device for detecting moving contacts. Its key technical features include a base, a detection rod for detecting the diameter of the mounting hole of the moving contact, and a detection component for detecting the position of the contact portion of the moving contact. The detection component is located on one side of the detection rod and includes a positioning rod, a positioning element, a measuring gauge, and a fixing block for fixing the measuring gauge. The positioning element is in contact with one side of the moving contact, the positioning rod is located on one side of the positioning element and can pass through the mounting hole of the moving contact, and the measuring gauge is located on the other side of the positioning element with its head contacting the contact portion of the moving contact.
[0005] The positioning structure used for contact detection in the aforementioned technical patents is relatively simple and cannot be adaptively adjusted according to contacts of different sizes, shapes, and dimensions. This causes the contacts to easily shift or shake during the detection process, affecting the accuracy and repeatability of the detection results and making it difficult to achieve comprehensive and integrated detection of the contacts.
[0006] Therefore, we propose a contact defect detection device with positioning and fixing detection function to solve the problems mentioned above. Utility Model Content
[0007] The purpose of this invention is to provide a contact defect detection device with positioning and fixing detection function, so as to solve the problem mentioned in the background art that the positioning component used for contact detection has a simple structure and cannot be adapted to contacts of different sizes, shapes and shapes, which makes the contacts prone to displacement or shaking during the detection process, affecting the accuracy and repeatability of the detection results, and making it difficult to achieve comprehensive and integrated detection of the contacts.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a contact defect detection device with positioning and fixing detection function, comprising a detection body, a controller, and support feet, wherein the controller is fixedly installed on one side of the detection body, and support feet are fixed at the four corners of the bottom of the detection body.
[0009] A fixed clamp is fixed to the upper end face of the testing machine body. A rubber pad is attached to one side of the fixed clamp. A sliding groove is formed on the upper end face of the testing machine body. An adjustment knob is provided on one side of the testing machine body. A lead screw is fixed to one end of the adjustment knob, and the other end of the lead screw is rotatably connected to the inner wall of the sliding groove. A slider is threaded to the outer surface of the lead screw, and the slider is in close sliding connection with the sliding groove. A movable clamp is fixed to the upper end face of the slider, and a rubber pad is attached to the side of the movable clamp facing the fixed clamp.
[0010] By adopting the above technical solution, the lead screw is rotated by turning the adjustment knob. The lead screw and the slider are connected by a thread, which drives the slider to slide along the slide groove. This causes the movable clamp to move closer to or away from the fixed clamp. The rubber pads attached to the fixed clamp and the movable clamp are used to firmly clamp and position contacts of different sizes, effectively preventing contact displacement or shaking during testing and ensuring testing accuracy.
[0011] Preferably, the two sides of the detection body are welded with fixed sleeves, the outer surface of the fixed sleeves is provided with a plurality of first insertion holes, the middle part of the fixed sleeves is embedded with a telescopic rod, the outer surface of the telescopic rod is provided with a second insertion hole, and a pin passes through the middle of the first insertion hole and the second insertion hole.
[0012] Using the above technical solution, the device has fixed sleeves on both sides of the testing machine body, and telescopic rods are embedded in the sleeves. The telescopic rods can extend and retract in the fixed sleeves. Through the first insertion hole and the second insertion hole opened on the outer surface, and the engagement with the pin, the extension length of the telescopic rods can be flexibly adjusted and fixed according to the actual testing needs.
[0013] Preferably, the first insertion holes are evenly distributed vertically along the outer surface of the fixing sleeve, and the diameter of the second insertion hole is adapted to the diameter of the first insertion hole.
[0014] With the above technical solution, the first insertion holes are evenly distributed along the outer surface of the fixed sleeve, so that when the telescopic rod is adjusted in the fixed sleeve, the second insertion holes on its outer surface can be precisely aligned with the first insertion holes at different heights, thus meeting diverse usage needs.
[0015] Preferably, a crossbar is welded to the top of the telescopic rod, a fixing sleeve is nested and securely connected to the outer surface of the crossbar, a fixing seat is fixed to the bottom of the fixing sleeve, a connecting seat is rotatably connected to the inner side of the fixing seat, and a fastening pin is threaded through and threaded to the middle of the fixing seat.
[0016] Using the above technical solution, a crossbar is welded to the top of the telescopic rod, a fixed sleeve is nested on the crossbar, and a fixed seat is connected to the bottom of the sleeve. The fixed seat can be adjusted in angle by rotating the connecting seat on the inner side, and the position of the connecting seat can be fixed by using the fastening pin in the middle. The angle of the fixed seat and its connected parts can be flexibly changed to adapt to the positioning and fixing requirements of different contact detection, thereby improving the adaptability of the detection device.
[0017] Preferably, two sets of fastening pins are arranged symmetrically along the connecting seat, and the ends of the fastening pins extend to and fit against the outside of the connecting seat.

[0020] Using the above technical solution, an industrial camera is fixed at the bottom of the connector, and the lamp cover on the outside is connected to the bottom of the connector by bolts. The lamp beads are distributed in a ring on the inner side of the bottom of the lamp cover, and the lamp cover is installed by screw holes and matching bolts. The lamp beads can provide illumination to ensure that the industrial camera can clearly capture contact images. At the same time, the lamp cover is easy to fix and disassemble, which meets the need to obtain clear visual inspection data when inspecting different contacts.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1. By setting a fixed clamp and a matching movable clamp on the upper surface of the testing machine body, and attaching rubber pads to one side of both the fixed and movable clamps, the friction between the clamp and the contact is greatly increased, effectively preventing the contact from slipping during testing.

The threaded connection between the lead screw and the slider allows the slider to slide smoothly within the slide groove, thereby flexibly adjusting the distance between the movable clamp and the fixed clamp. This allows for easy adaptation to contacts of different sizes, achieving precise and secure clamping and positioning, effectively preventing contact displacement or shaking during testing, significantly improving the accuracy and repeatability of the test results, and providing a solid guarantee for the efficient and reliable conduct of contact defect detection.
[0023] 2. The crossbar, fixed sleeve, fixed seat, and connecting seat at the top of the telescopic rod cooperate with each other. With the help of two sets of centrally symmetrical and adjustable fastening pins, the connecting seat can rotate at multiple angles and be securely locked inside the fixed seat. This allows for flexible adjustment of the shooting angle of the industrial camera. The lamp cover on the outside of the industrial camera is connected by bolts and screw holes, making it easy and stable to install. The ring-shaped LED beads on the bottom inner side provide sufficient and uniform illumination, ensuring that the industrial camera can clearly capture contact images in any environment. This provides clear and high-quality visual data for contact defect detection, greatly improving the accuracy and reliability of the detection results. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0031] Please see Figures 1-5This utility model provides a technical solution: a contact defect detection device with positioning and fixing detection function, including a detection body 1, a controller 2 and support feet 3. The controller 2 is fixedly installed on one side of the detection body 1, and support feet 3 are fixed at the four corners of the bottom of the detection body 1. A fixing clamp 4 is fixed on the upper end face of the detection body 1, and a rubber pad 5 is attached to one side of the fixing clamp 4.

A lead screw 8 is fixed to one end of the adjustment knob 7, and the other end of the lead screw 8 is rotatably connected to the inner wall of the sliding groove 6. A slider 9 is threadedly connected to the outer surface of the lead screw 8, and the slider 9 is in close sliding connection with the sliding groove 6. A movable clamp 10 is fixed on the upper end face of the slider 9, and a rubber pad 5 is attached to the side of the movable clamp 10 facing the fixed clamp 4.
[0032] The testing machine body 1 is the main body, with a controller 2 fixedly installed on one side for controlling the overall operation, and support feet 3 at the four corners of the bottom for stable support. On the upper surface of the testing machine body 1, a rubber pad 5 is attached to one side of the fixed clamp 4 to increase the friction with the contact and prevent the contact from sliding. A slide groove 6 is opened on the upper surface of the testing machine body 1, and an adjustment knob 7 is set on one side. One end of the knob is fixed to a lead screw 8, and the other end is rotatably connected to the inner wall of the slide groove 6. When the adjustment knob 7 is turned, the lead screw 8 rotates accordingly, and the slider 9, which is threaded to the lead screw 8, slides in the slide groove 6. This causes the movable clamp 10 fixed on the upper surface of the slider 9 to move closer to or away from the fixed clamp 4. The side of the movable clamp 10 facing the fixed clamp 4 is also attached with a rubber pad 5. The adjustment knob 7 can be turned according to the size of the contact to make the fixed clamp 4 and the movable clamp 10 firmly clamp and position contacts of different sizes, avoiding contact displacement or shaking during testing, ensuring the accuracy and repeatability of the test results, and realizing comprehensive testing of the contacts.
[0033] The testing body 1 has fixed sleeves 11 welded to both sides. Several first insertion holes 12 are formed on the outer surface of the fixed sleeves 11. A telescopic rod 13 is embedded in the middle of the fixed sleeves 11. A second insertion hole 14 is formed on the outer surface of the telescopic rod 13. A pin 15 passes through the middle of the first insertion holes 12 and the second insertion hole 14. The first insertion holes 12 are evenly distributed vertically along the outer surface of the fixed sleeves 11, and the diameter of the second insertion holes 14 matches the diameter of the first insertion holes 12. A crossbar 16 is welded to the top of the telescopic rod 13. A fixed clamp 17 is nested and securely connected to the outer surface of the crossbar 16. A fixed seat 18 is fixed to the bottom of the fixed clamp 17. A connecting seat 19 is rotatably connected to the inner side of the fixed seat 18. A fastening pin 20 is threaded through and threaded into the middle of the fixed seat 18. Two sets of fastening pins 20 are arranged symmetrically along the connecting seat 19, and the ends of the fastening pins 20 extend to and fit against the outer side of the connecting seat 19. An industrial camera 21 is fixedly installed at the bottom of the connector 19. A lamp cover 22 is fitted on the outside of the industrial camera 21. A screw hole 23 is opened at the upper end of the lamp cover 22. A bolt 24 that matches the screw hole 23 passes through the bottom of the connector 19. Several LED beads 25 are arranged in a ring on the inner side of the bottom of the lamp cover 22.
[0034] Fixed sleeves 11 are welded to both sides of the testing body 1. Several first insertion holes 12 are evenly distributed on the outer surface of the sleeves 11. A telescopic rod 13 with a second insertion hole 14 is embedded in the fixed sleeve 11. By passing a pin 15 through the first insertion hole 12 and the second insertion hole 14 with the appropriate hole diameter, the extension length of the telescopic rod 13 can be flexibly adjusted and fixed. A fixed clamp 17 is nested and fastened to the crossbar 16 welded to the top of the telescopic rod 13. The fixed seat 18 at the bottom of the fixed clamp 17 is rotatably connected to the connecting seat 19. After rotating the connecting seat 19, two sets of centrally symmetrically arranged clamps can be connected by the thread in the middle of the fixed seat 18. The fastening pin 20 fixes its position, and the end of the fastening pin 20 fits against the outside of the connecting seat 19 to ensure the stability of the fixation. The industrial camera 21 is fixedly installed at the bottom of the connecting seat 19. The lamp cover 22 sleeved on the outside is installed by the bolt 24 at the bottom of the connecting seat 19 and the screw hole 23 at the top of the lamp cover 22. The LED beads 25 distributed in a ring on the bottom inner side of the lamp cover 22 provide illumination. The height and angle of the industrial camera 21 can be flexibly adjusted according to the detection requirements, while ensuring its stability. The illumination by the LED beads 25 enables the industrial camera 21 to clearly capture contact images, providing clear and accurate visual data for contact defect detection.
[0035] Working principle: For this type of contact defect detection device with positioning and fixing detection function, the fixed clamp 4 on the upper end face of the detection body 1 increases the friction with the contact to prevent slippage by means of a rubber pad 5 attached to one side. Rotating the adjustment knob 7 on one side of the detection body 1 drives the screw 8 fixed at one end to rotate in the inner wall of the slide groove 6. The screw 8 drives the threaded slider 9 to slide in the slide groove 6, thereby allowing the movable clamp 10 on the upper end face of the slider 9 to move closer to or away from the fixed clamp 4, realizing the firm clamping and positioning of contacts of different sizes, ensuring detection accuracy. At the same time, the fixed sleeves 11 welded on both sides of the detection body 1 have first insertion holes 12 evenly distributed on their outer surface and second insertion holes 14 on the outer surface of the embedded telescopic rod 13, which are penetrated by pins 15. The extension length of the telescopic rod 13 is adjusted and fixed by an adapter socket; a fixed sleeve 17 is nested and tightened on the top crossbar 16 of the telescopic rod 13, and the bottom fixed seat 18 is rotatably connected to the connecting seat 19. The position of the connecting seat 19 is fixed by two sets of centrally symmetrical fastening screws 20 connected by the thread in the middle of the fixed seat 18 to ensure stability; an industrial camera 21 is installed at the bottom of the connecting seat 19, and a lamp cover 22 is fitted on the outside and installed by the bolt 24 at the bottom of the connecting seat 19 and the screw hole 23 at the top of the lamp cover 22. The ring lamp 25 on the bottom inner side of the lamp cover 22 provides illumination. The height and angle of the industrial camera 21 can be flexibly adjusted and stability is ensured so that it can clearly capture contact images using the illumination of the lamp 25, providing accurate visual data for comprehensive detection of contact defects.
