Description

Technical Field

[0001] The invention belongs to the technical field of contact detection, in particular to a contact pressing force detection device. Background Art

[0002] The contact clamping force detection equipment is a special test instrument used to measure the clamping force of the metal contact inside the contact (usually refers to the contact part in electrical equipment); At present, the traditional contact pressing force detection equipment is to place the contact component on the top of the rotating platform, and then drive the pressure detection component to insert into the inside of the contact component, and then rotate the rotating platform to allow the pressure detection component to enter between the two metal contact pieces of the contact to detect the pressing force of the metal contact pieces; However, in actual application scenarios, especially when the pressure detection component rotates with the rotating platform, the detection component may be subjected to an outward thrust due to the centrifugal force generated by the rotation. This thrust may cause the detection component to shift slightly. This shift may cause the pressure detection component to be unable to be accurately positioned at the predetermined position of the contact component, thereby affecting the stability of the detection. Once the position of the detection component deviates, the data it measures may not truly reflect the actual clamping force of the contact component, thereby reducing the reliability of the detection result.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 9 As shown, the present invention provides a contact pressing force detection device, including a base plate 1, a workbench 2 is fixedly installed on the top of the base plate 1, a mounting frame 3 is arranged on the top of the base plate 1 and located on both sides of the workbench 2, a display component 35 is arranged on the top of the base plate 1, a rotating platform 5 is rotatably connected inside the workbench 2, and a contact component 6 is arranged on the top of the rotating platform 5; A limiting mechanism is arranged on the surface of the rotating platform 5, and the limiting mechanism includes a connecting shell 7, which is fixedly connected to the surface of the rotating platform 5, and a tooth plate 8 is rotatably connected inside the connecting shell 7. Two sliding grooves 9 are provided on the surface of the tooth plate 8, and two sliders 10 are slidably connected inside the two sliding grooves 9. A connecting plate 11 is fixedly installed on the top of the two sliders 10, and a mounting plate 12 is fixedly installed on the top of the connecting plate 11. A contact block 13 is provided on the bottom end of the mounting plate 12. A motor 14 is fixedly installed on the top of the connecting shell 7, and the output end of the motor 14 extends to the inside of the connecting shell 7, and a gear 15 meshing with the tooth plate 8 is fixedly installed.

[0019] The above scheme is adopted: the operator places the contact component 6 on the top of the rotating platform 5, and then the motor 14 can be driven to rotate the gear 15, because the gear 15 is meshed with the tooth plate 8, and then the rotating gear 15 will drive the tooth plate 8 to rotate, and when the tooth plate 8 rotates, the slider 10 will slide inside the sliding groove 9, and then the two sliders 10 will move toward the surface of the contact component 6, and the slider 10 will drive the connecting plate 11, the mounting plate 12 and the contact block 13 to move toward the surface of the contact component 6, and then the mounting plate 12 and the contact block 13 will be inserted into the interior of the contact component 6, and the surface of the contact block 13 will contact one side of the interior of the contact component 6, so that the contact component 6 can be limited; After the limiting is completed, the mounting frame 3 and the pressure detection component 4 can be driven to move toward the surface of the contact component 6, and then the pressure detection component 4 will be inserted into the interior of the contact component 6, and then the rotating platform 5 can be driven to rotate, and the rotating platform 5 will drive the contact component 6 and the limiting mechanism to rotate, and then the pressure detection component 4 will enter between the two metal contact pieces inside the contact component 6, and then detect the clamping force of the metal contact pieces, and the detected data will be displayed on the surface of the display component 35, and finally the contact block 13 is limited to the contact component 6 by driving the motor 14, thereby improving the stability of the detection of the contact component 6 and ensuring the accuracy of the detected value.

[0020] like Figure 5 and Figure 6 As shown, it also includes: a fixing mechanism, which is arranged at the top of the connecting shell 7, and the fixing mechanism includes a fixing shell 17, and the fixing shell 17 is fixedly connected to the top of the connecting shell 7; A fixing groove 16 is provided on one side of the two connecting plates 11 close to the fixed shell 17, and a gear 2 18 is rotatably connected inside the fixed shell 17. A screw rod 19 is fixedly installed on one side of the gear 2 18, and a screw rod 19 is threadedly connected on the surface of the screw rod 19 to an extrusion block 20 located inside the fixed shell 17. Two connecting plates 21 are fixedly installed on one side of the two connecting plates 11 away from the workbench 2, and a rack 22 meshing with the gear 2 18 is fixedly installed on the opposite side of the two connecting plates 21.

[0021] The above scheme is adopted: through the design of the fixing mechanism, when the connecting plate 11 moves toward the surface of the contact component 6, the connecting plate 11 will link the connecting plate 21 to move, and the connecting plate 21 will drive the rack 22 to move. Because the rack 22 is meshed with the gear 2 18, the moving rack 22 will drive the gear 2 18 to rotate, and the gear 2 18 will drive the screw rod 19 to rotate. Since the screw rod 19 is threadedly connected with the extrusion block 20, the extrusion block 20 will move on the surface of the screw rod 19, and then one end of the extrusion block 20 will enter the interior of the fixed groove 16, so that the connecting plate 11 can be limited. Finally, the extrusion block 20 enters the interior of the fixed groove 16 through the connecting plate 11 linkage rack 22, so that the connecting plate 11 limits the contact component 6 while fixing the connecting plate 11, thereby improving the stability of the limit plate during the detection process and reducing the error of the detection data.

[0022] like Figure 7 and Figure 8 As shown, it also includes: a disassembly mechanism, which is arranged inside the mounting plate 12, and the disassembly mechanism includes a spring 24, and the spring 24 is fixedly connected to the inside of the mounting plate 12; The top of the contact block 13 is fixedly installed with an insert block 23 located inside the mounting plate 12, one end of a spring 24 is fixedly installed with a moving plate 25, one side of the moving plate 25 is fixedly installed with a limit block 26 located inside the insert block 23, the top of the mounting plate 12 is rotatably connected with a rotating rod 28, the rotating rod 28 extends downward to the inside of the mounting plate 12, and is fixedly installed with a push rod 29, and a protrusion 27 located inside the push rod 29 is fixedly installed in the middle of the top of the moving plate 25.

[0023] The above scheme is adopted: through the design of the disassembly mechanism, when the contact block 13 needs to be replaced after a long period of limiting work, the rotating rod 28 can be rotated, and the rotating rod 28 will drive the push rod 29 to rotate. When the push rod 29 rotates, the protrusion 27 will slide inside the push rod 29. At this time, the push rod 29 will push the protrusion 27 to move, and the protrusion 27 will drive the moving plate 25 and the limiting block 1 26 to move. When the moving plate 25 moves, the spring 1 24 will be stretched, and then the limiting block 1 26 will move away from the inside of the plug block 23. When the limiting block 1 26 moves away from the inside of the rotating rod 28, The fixation of the mounting plate 12 will be cancelled, and then the severely worn contact block 13 can be removed, and the unused contact block 13 can be placed at the bottom of the mounting plate 12, and the plug block 23 can be inserted into the interior of the mounting plate 12 again. At this time, the rotating rod 28 can be loosened, and then the stretched spring 1 24 will pull the movable plate 25 to reset, and the limit block 1 26 will be inserted into the interior of the plug block 23 again, and then the contact block 13 can continue to limit the work, and finally the movable plate 25 can be moved by rotating the rotating rod 28, so that it is convenient for the operator to replace the contact block 13, thereby increasing the convenience of the equipment.

[0024] like Figure 7 and Figure 8 As shown, a slide rail 30 located inside the movable plate 25 is fixedly installed inside the mounting plate 12, and the movable plate 25 can slide inside the slide rail 30. The slide rail 30 is square in design and has a relatively smooth surface.

[0025] The above solution is adopted: through the design of the slide rail 30, when the protrusion 27 pushes the movable plate 25 to move, the movable plate 25 will slide on the surface of the slide rail 30, so that the slide rail 30 can limit the moving movable plate 25, and the slide rail 30 is designed to be smooth, so that the movable plate 25 can move more smoothly.

[0026] like Figure 6 and Fig. 9 As shown, a spring 2 31 is fixedly installed on one side inside the fixing groove 16, and a limiting block 2 32 is fixedly installed on one end of the spring 2 31. A square hole 36 is provided on the top of the connecting shell 7, and limiting grooves 33 are provided on both sides inside the square hole 36. The inside of the limiting grooves 33 is slidably connected to a limiting block 3 34, and one end of the limiting block 34 is fixedly connected to the surface of the connecting plate 11.

[0027] The above scheme is adopted: through the design of the second spring 31 and the second limit block 32, when the extrusion block 20 enters the interior of the fixing groove 16, it will contact one side of the second limit block 32, and then the second limit block 32 will squeeze the second limit block 32 to move, and when the second limit block 32 moves, the second spring 31 will be compressed, and then through the compression of the second spring 31 and the cooperation between the extrusion block 20 and the second limit block 32, the connection plate 11 can be fixed, thereby increasing the stability of its detection, and when the two connection plates 11 are away from the contact component 6 When the connecting plate 11 is moved, the spring 2 31 will continue to be compressed, and the extrusion block 20 will not block the movement of the connecting plate 11. Through the design of the limiting groove 33, the limiting block 34 and the square hole 36, when the connecting plate 11 moves, it will slide inside the square hole 36, and then the connecting shell 7 will not interfere with the inside of the connecting plate 11, and the moving connecting plate 11 will drive the limiting block 34 to move inside the limiting groove 33, and then the moving limiting block 34 can limit the connecting plate 11 to ensure the stability of the movement of the connecting plate 11.

[0028] like Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the contact block 13 is designed to be longitudinally symmetrical about the center of the mounting frame 3, and the opposite sides of the two contact blocks 13 are both chamfered, the contact block 13 is made of rubber material, and the contact block 13 is rough in design, and the opposite sides of the extrusion block 20 and the limit block 2 32 are both inclined, and the two inclined surfaces are parallel to each other.

[0029] The above scheme is adopted: through the design of the contact block 13, since the contact block 13 is chamfered, it is convenient for the contact block 13 to enter the interior of the contact component 6. Since the contact block 13 is made of rubber material, when the contact block 13 contacts one side of the interior of the contact component 6, it will deform so that it can fully contact the inner wall of the contact component 6, and the contact component 6 is rough in design, thereby improving the limiting effect of the contact component 6. Through the design of the extrusion block 20 and the limit block 32, since the sides opposite to the extrusion block 20 and the limit block 32 are both inclined and parallel to each other, when the extrusion block 20 enters the interior of the fixed groove 16 and contacts one side of the limit block 32, the resistance between the extrusion block 20 and the limit block 32 can be reduced, which facilitates the extrusion block 20 to squeeze and push the limit block 32 to move.

[0030] like Figure 4 , Figure 7 and Figure 8 As shown, the sliding groove 9 is of curved design, the slider 10 is of cylindrical design, and the surface of the slider 10 contacts the inner wall of the sliding groove 9. There are two limit blocks 26, and the limit blocks 26 are designed to be laterally symmetrical about the center of the moving plate 25. The two limit blocks 26 are of square design, and one end of the limit blocks 26 is chamfered.

[0031] The above scheme is adopted: through the design of the sliding groove 9 and the slider 10, since the sliding groove 9 is a curved design, when the tooth plate 8 rotates, the slider 10 will move along the curved trajectory of the sliding groove 9, so that the slider 10 can drive the mounting plate 12 and the contact block 13 to move toward the inside of the contact component 6, and the surface of the slider 10 contacts the inner wall of the sliding groove 9, so that the slider 10 can move more smoothly, through the design of the limit block 1 26, since the limit block 1 26 is a square design, when entering the inside of the plug block 23, the contact area with the inner wall of the plug block 23 is increased, thereby improving its fixing effect, and one end of the limit block 1 26 is chamfered, so that it is convenient for the limit block 1 26 to enter the inside of the plug block 23.

[0032] The working principle and use process of the present invention: First, the operator places the contact component 6 on the top of the mounting frame 3. At this time, the motor 14 can be driven to rotate the gear 15, and the gear 15 drives the toothed plate 8 and the sliding groove 9 to rotate. Then the slider 10 will move toward the surface of the contact component 6 along the curved track of the sliding groove 9. The slider 10 will drive the connecting plate 11, the mounting plate 12 and the contact block 13 to move toward the surface of the contact component 6. Then the mounting plate 12 and the contact block 13 will enter the interior of the contact component 6, and the surface of the contact block 13 will contact one side of the interior of the contact component 6, so that the contact component 6 can be limited to increase the stability of its detection. When the connecting plate 11 moves toward the surface of the contact component 6, the connecting plate 11 will link the connecting plate 21 and the rack 22 to move, the rack 22 will drive the gear 2 18 and the screw 19 to rotate, and the extrusion block 20 will move on the surface of the screw 19, and then one end of the extrusion block 20 will enter the inside of the fixed groove 16. When the extrusion block 20 enters the inside of the fixed groove 16, it will contact one side of the limit block 2 32 and squeeze the limit block 2 32 to move, then the spring 2 31 will be compressed, and then through the compression of the spring 2 31 and the extrusion block 20 and the limit block The two 32 cooperate with each other, and then the connecting plate 11 can be fixed. After the fixing is completed, the mounting frame 3 and the pressure detection component 4 can be driven to move toward the surface of the contact component 6, and then the pressure detection component 4 will be inserted into the inside of the contact component 6, and then the rotating platform 5 can be driven to rotate, and the rotating platform 5 will drive the contact component 6 and the limit mechanism to rotate, and then the pressure detection component 4 will enter between the two metal contact pieces inside the contact component 6, and then detect the pressing force of the metal contact pieces, and the detected data will be displayed on the surface of the display component 35; When the contact block 13 needs to be replaced after being limited for a long time, the rotating rod 28 and the pushing rod 29 can be rotated, and the pushing rod 29 will push the protrusion 27, the movable plate 25 and the limiting block 26 to move. When the movable plate 25 moves, the spring 24 will be stretched, and then the limiting block 26 will move away from the inside of the plug-in block 23, and then the limiting of the plug-in block 23 will be cancelled, and then the severely worn contact block 13 can be removed, and the unused contact block 13 can be installed on the bottom of the mounting plate 12. At this time, the rotating rod 28 can be loosened, and then the stretched spring 24 will pull the movable plate 25 to reset, and the limiting block 26 will be inserted into the inside of the plug-in block 23 again, and then the contact block 13 can continue to perform the limiting work, and finally complete the operation process.
