Description

Technical Field

[0001] This utility model relates to the field of electrical equipment testing technology, specifically to a contact wear detection device that facilitates contact point positioning. Background Technology

[0002] In electrical equipment, contacts are important conductive components, and their performance directly affects the normal operation of the equipment. With long-term use, contacts will wear down due to frequent opening and closing operations, arc erosion, and other factors. If the wear of contacts is not detected in time, it may lead to increased contact resistance, overheating, or even electrical faults.

[0003] However, existing contact wear detection equipment still has some problems:

[0004] An existing contactor contact automatic detection device, such as one described in application number CN201721101121.0, includes a base, vertical plates, a moving contact detection device, and a stationary contact detection device. The base is fixed on a support. The two vertical plates are arranged vertically and parallel to each other, and the lower ends of the two vertical plates are fixed to the base. The moving contact detection device and the stationary contact detection device are respectively connected to the upper ends of the two vertical plates.

[0005] Because the installation position of the contacts may have some deviation, and the size and shape of different models of contacts are slightly different, existing contact wear detection equipment has difficulty in quickly and accurately finding the contact point position of the contacts, thus affecting the accuracy of the detection results and the detection efficiency.

[0006] Therefore, we propose a contact wear detection device that facilitates contact point positioning in order to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide a contact wear detection device that facilitates contact point positioning, in order to solve the problem mentioned in the background art that existing contact wear detection devices are unable to quickly and accurately locate the contact point due to the possible deviation in the installation position of the contact and the slight differences in the size and shape of different models of contacts, thus affecting the accuracy and efficiency of the detection results.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a contact wear detection device for easy contact point positioning, comprising a detection body and a display screen:

[0009] A display screen is installed on the outer end face of the detection body, and a disc is fixedly installed on the upper end face of the detection body. A first sliding groove is formed on the outer surface of the disc, and three sets of the first sliding groove are distributed in a ring along the outer surface of the disc. A limiting rod corresponding to the first sliding groove is fixedly installed inside the disc. A second sliding groove is formed in the middle of the limiting rod. An electric push rod is fixed on the inner side wall of the limiting rod. A gripper is fixed at the extended end of the electric push rod. A slider is fixed at the bottom end of the gripper, and the slider is in close sliding connection with the second sliding groove. A clamping groove is formed on the outer surface of the gripper.

[0010] By adopting the above technical solution, a first sliding groove with a ring distribution corresponding to the limiting rod is set on the disc on the upper end face of the detection machine body. With the help of the electric push rod on the inner side wall of the limiting rod, the gripper can be driven to slide along the second sliding groove, thereby realizing the clamping of contacts at different positions. The clamping groove on the outer surface of the gripper can help fix the contacts, making it easier to accurately position the contacts, solving the problem of difficult positioning in existing equipment, and improving the accuracy and efficiency of the detection results.

[0011] Preferably, an L-shaped fixing frame is welded to one side of the detection body, a motor is fixedly installed at the top of the fixing frame, a drive shaft is movably connected to the output end of the motor, a connecting rod is fixed at the bottom end of the drive shaft, and a fixing rod is installed at the top end of the connecting rod.

[0012] By adopting the above technical solution, the motor on the L-shaped fixing frame drives the drive shaft to rotate, which in turn causes the connecting rod connected to the drive shaft to move. This allows for flexible adjustment of the positions of the connecting rod and the fixing rod, which can assist in the operation or testing of contacts in different positions and postures. It helps to solve the testing problems caused by contact installation position deviations and various models, and improves testing efficiency and accuracy.

[0013] Preferably, one end of the connecting rod is designed to be perpendicular to the bottom end of the drive shaft, and the top end of the fixing rod is designed to be perpendicular to the other end of the connecting rod.

[0014] By adopting the above technical solution, the design of the connecting rod being perpendicular to the drive shaft and the fixed rod being perpendicular to the connecting rod enables the fixed rod to undergo eccentric circular motion when the motor drives the drive shaft to rotate. This allows the fixed rod to move around the drive shaft as an axis, enabling contact detection at different positions and angles and enhancing the equipment's adaptability to complex contact detection scenarios.

[0015] Preferably, a fixed sleeve is fitted on the outer surface of the fixed rod, a hinge is provided on one side of the fixed sleeve, and a movable sleeve is rotatably connected to the outer side of the fixed sleeve through the hinge. A fastening bolt is threaded through and threaded to the other side of the fixed sleeve and the movable sleeve.

[0016] Using the above technical solution, the fixed sleeve and the movable sleeve are connected by a hinge, which can rotate and open around the hinge. The two sleeves are then fastened by a fastening bolt that passes through them and is threaded together, so that the fixed sleeve and the movable sleeve can be firmly fixed on the fixed rod. The position of the sleeve on the fixed rod can be adjusted according to the needs to meet diverse testing requirements.

[0017] Preferably, a rotating shaft is rotatably connected to the inner side of the fixed sleeve, a fixing block is fixed to the inner side of the rotating shaft, a laser scanning head is fixed to the outer side of the fixing block, and an adjusting bolt is threaded through and threaded to the outer side of the fixed sleeve, with the end of the adjusting bolt being in contact with the side end face of the rotating shaft.

[0018] Using the above technical solution, the fixed sleeve is connected to the fixed block through a rotating shaft, so that the laser scanning head fixed on the fixed block can rotate flexibly around the rotating shaft. By tightening or loosening the adjusting bolt, the rotation angle of the laser scanning head can be controlled and fixed, thereby enabling precise adjustment of the position of the laser scanning head to perform all-round scanning of the contact, helping to detect the wear of the contact more efficiently and accurately.

[0019] Preferably, the bottom of the detection body has base columns evenly distributed at the four corners, a threaded column is threadedly connected to the middle of the base column, a hexagonal piece is nested on the outer surface of the threaded column, and a support foot is fixed at the bottom end of the threaded column.

[0020] The above technical solution is adopted. The bottom of the testing machine is provided with four base columns at the four corners. The threaded column is threadedly connected to the base column. By rotating the hexagonal part, the threaded column can be moved up and down, which can flexibly adjust the height of the support feet, so that the testing equipment can remain stable on different placement planes and ensure the stability of the testing process.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. A disc fixed to the upper surface of the testing machine has three sets of first sliding grooves distributed in a ring on its outer surface. Inside the disc are corresponding limiting rods, and a second sliding groove is opened in the middle of the limiting rods. An electric push rod is fixed to the inner wall of the limiting rods, and its extended end is connected to a gripper. The slider at the bottom of the gripper slides in contact with the second sliding groove. When the electric push rod is activated, it pushes the gripper to move along the second sliding groove. Due to the guiding effect of the first sliding groove, the three sets of grippers can move closer to or away from the center of the disc simultaneously. The grooves on the outer surface of the gripper can accommodate contacts of different sizes and shapes. By precisely adjusting the position of the gripper, the contact point can be quickly and accurately positioned, solving the contact point positioning problem caused by the deviation of the contact installation position and the variety of models in existing equipment, and improving the accuracy and efficiency of the test results.

[0023] 2. When it is necessary to adjust the height and level of the testing machine, the operator can use a tool to rotate the hexagonal piece. Utilizing the threaded engagement principle, the threaded post moves up and down in the base post, thereby causing the support feet to rise or fall. By adjusting the height of the threaded post at each of the four base posts, the testing equipment can adapt to placement surfaces with different flatness, ensuring that the testing machine is always in a level and stable state. This provides a stable and reliable support foundation for accurately detecting contact wear and avoids interference with the testing results due to unstable equipment placement.

[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 wear detection device for easy contact point positioning, including a detection body 1 and a display screen 2. The display screen 2 is installed on the outer end face of the detection body 1. A disc 16 is fixedly installed on the upper end face of the detection body 1. A first sliding groove 17 is opened on the outer surface of the disc 16, and three sets of the first sliding groove 17 are distributed in a ring along the outer surface of the disc 16. A limiting rod 18 corresponding to the first sliding groove 17 is fixedly installed inside the disc 16. A second sliding groove 19 is opened in the middle of the limiting rod 18. An electric push rod 20 is fixed on the inner side wall of the limiting rod 18. A gripper 21 is fixed at the extended end of the electric push rod 20. A slider 22 is fixed at the bottom end of the gripper 21, and the slider 22 is in close sliding connection with the second sliding groove 19. A clamping groove 23 is opened on the outer surface of the gripper 21.

[0032] The testing body 1 is the main body of the equipment. The display screen 2 installed on the outer end face is used to display the test data. The disc 16 fixed on the upper end face of the testing body 1 has three sets of first sliding grooves 17 distributed in a ring on its outer surface. The corresponding limiting rod 18 inside the disc 16 has a second sliding groove 19 in the middle of the limiting rod 18. The electric push rod 20 fixed on the inner side wall of the limiting rod 18 has a claw 21 connected to its extended end. The slider 22 at the bottom of the claw 21 slides in contact with the second sliding groove 19. When the electric push rod 20 is activated, it pushes the claw 21 to move along the second sliding groove 19. Due to the guiding effect of the first sliding groove 17, the three sets of claws 21 can move closer to or away from the center of the disc 16 at the same time. The clamping groove 23 on the outer surface of the claw 21 can adapt to contacts of different sizes and shapes. By precisely adjusting the position of the claw 21, the contact point can be quickly and accurately positioned, solving the contact point positioning problem caused by the deviation of the contact installation position and the variety of models in the existing equipment, and improving the accuracy and efficiency of the test results.

[0033] An L-shaped mounting bracket 3 is welded to one side of the testing unit 1. A motor 4 is fixedly mounted on the top of the mounting bracket 3. A drive shaft 5 is movably connected to the output end of the motor 4. A connecting rod 6 is fixed to the bottom end of the drive shaft 5, and a fixing rod 7 is mounted on the top end of the connecting rod 6. One end of the connecting rod 6 is perpendicular to the bottom end of the drive shaft 5, and the top end of the fixing rod 7 is perpendicular to the other end of the connecting rod 6. A fixing sleeve 8 is fitted onto the outer surface of the fixing rod 7. A hinge 9 is provided on one side of the fixing sleeve 8. A movable sleeve 10 is rotatably connected to the outer side of the fixing sleeve 8 via the hinge 9. A fastening bolt 11 is threaded through and threaded onto the other side of the fixing sleeve 8 and the movable sleeve 10. A rotating shaft 12 is rotatably connected to the inner side of the fixing sleeve 8. A fixing block 13 is fixed to the inner side of the rotating shaft 12. A laser scanning head 14 is fixed to the outer side of the fixing block 13. An adjusting bolt 15 is threaded through and threaded onto the outer side of the fixing sleeve 8, and the end of the adjusting bolt 15 is in contact with the side end face of the rotating shaft 12.

[0034] An L-shaped fixing frame 3 welded to one side of the inspection body 1 has a motor 4 fixed at its top. The output end of the motor 4 is connected to the drive shaft 5. Since one end of the connecting rod 6 is perpendicular to the bottom end of the drive shaft 5, the operation of the motor 4 can drive the perpendicular connecting rod 6 to rotate in the plane. The top end of the fixing rod 7 is designed to be perpendicular to the other end of the connecting rod 6, further expanding the motion dimension. The fixing sleeve 8 outside the fixing rod 7 is rotatably connected to the movable sleeve 10 via a hinge 9. Tightening the fastening bolt 11 can adjust the opening and closing of the two, thereby firmly clamping different tools or parts. The rotating shaft 12 is rotatably connected to the inside of the fixing sleeve 8. The laser scanning head 14 is fixed to the outside of the fixed block 13. When the angle of the laser scanning head 14 needs to be adjusted, the adjusting bolt 15 passing through the outside is loosened, the laser scanning head 14 is rotated to the appropriate position, and then the adjusting bolt 15 is tightened to fix it. Thus, under the drive of the motor 4, the laser scanning head 14 can move around the drive shaft 5, and the laser scanning head 14 can rotate around the contact. This allows for precise adjustment of the detection position and angle, while adapting to the detection needs of different contacts, thus helping to improve the comprehensiveness and accuracy of contact wear detection.

[0035] The bottom of the testing body 1 has four evenly distributed bottom posts 24, and the middle of the bottom posts 24 is threaded with a threaded post 25. The outer surface of the threaded post 25 is nested with a hexagonal piece 26, and the bottom end of the threaded post 25 is fixed with a support foot 27.

[0036] The bottom of the testing machine body 1 is evenly equipped with four base columns 24 at its four corners. The middle of the base column 24 is threadedly connected to the threaded column 25. The threaded column 25 is nested with a hexagonal piece 26, and the bottom end of the threaded piece 26 is fixed with a support foot 27. When it is necessary to adjust the height and level of the testing machine body 1, the operator can use a tool to rotate the hexagonal piece 26. By utilizing the threaded engagement principle, the threaded column 25 can be moved up and down in the base column 24, thereby driving the support foot 27 to rise or fall. By adjusting the height of the threaded column 25 at each of the four base columns 24, the testing equipment can be adapted to the placement surface with different flatness, ensuring that the testing machine body 1 is always in a horizontal and stable state. This provides a stable and reliable support foundation for accurately detecting the wear of the contact points and avoids interference with the test results due to unstable placement of the equipment.

[0037] Working principle: For this type of contact wear detection equipment that facilitates contact point positioning, the disc 16 on the upper surface of the detection body 1, through three sets of annularly distributed first sliding grooves 17 and corresponding internal limiting rods 18, in conjunction with the second sliding groove 19 in the middle of the limiting rods 18 and the electric push rod 20 on the inner side wall, drives the gripper 21 to move along the second sliding groove 19 through the bottom slider 22. The clamping groove 23 outside the gripper 21 precisely adapts to various contacts, realizing rapid contact point positioning. The motor 4 at the top of the L-shaped fixing frame 3 on one side drives the drive shaft 5, which is connected by a connecting rod. The perpendicular design of the drive shaft 5, the fixed rod 7, and the connecting rod 6 expands the motion dimension. The fixed sleeve 8 and the movable sleeve 10 are fixed to the fixed rod 7 via the hinge 9 and the fastening bolt 11. The fixed sleeve 8 has a built-in rotating shaft 12 that connects to the fixed block 13 and the outer laser scanning head 14. The angle can be adjusted by the adjusting bolt 15. It rotates around the contact for detection as the motor 4 rotates. This allows for precise adjustment of the detection position and angle, while adapting to the detection needs of different contacts, thus helping to improve the comprehensiveness and accuracy of contact wear detection.

[0038] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
