Description

Technical Field

[0001] This application relates to the field of switch detection, and more particularly to a detector for detecting switches. Background Technology

[0002] Currently, with the rapid development of modern technology and information, electronic switches are being used more and more. Existing switch life detectors use cylinders for testing. This type of switch life tester is completed by the action of the cylinder. The lifespan of the switch is tested as the pressure of the cylinder changes.

[0003] Regarding the aforementioned technologies, there are still some shortcomings: When testing switches of different specifications and sizes, the transport distance of the switches needs to be adjusted. Since existing detectors often use cylinders as moving parts, if some of the switches being tested are too small, the detector's gripping component cannot accurately grip switches of different specifications, or additional adjustments to the cylinder's stroke are required, which is quite troublesome. Even when the switches can be gripped, it may be difficult to align the switches with the detection components during movement, so further improvements are needed. Utility Model Content

[0004] In order to meet the requirements of grasping and detecting different types of switches, this application provides a detector for detecting switches.

[0005] This application provides a detector for detecting switches, which adopts the following technical solution: A detector for detecting switches includes a feeding assembly, a clamping assembly, and a detection assembly. The clamping assembly includes a support rod and a mounting plate disposed on the support rod. The mounting plate has a cavity, and a control screw is rotatably connected within the cavity. Hooks are slidably connected to both ends of the mounting plate. Each hook is connected to a drive screw. The drive screw is threadedly connected to the control screw, and the two ends of the control screw have threads in opposite directions. The detection assembly is located below the hooks.

[0006] By adopting the above technical solution and controlling the reverse thread design at both ends of the screw, the synchronous reverse movement of the two hooks is achieved, ensuring balanced force when clamping the switch and avoiding skewing. The detection component is located directly below the hooks, realizing the integration of clamping and detection stations and improving detection efficiency.

[0007] Optionally, sealing blocks are slidably provided at both ends of the cavity, the sealing blocks are used to cover the corresponding ends of the cavity, and a spring is connected between the sealing blocks and the mounting plate.

[0008] By adopting the above technical solution, the spring-driven sealing block automatically seals the cavity port, preventing dust from entering, protecting the internal screw mechanism, and extending its service life.

[0009] Optionally, the outer surface of the sealing block is provided with multiple anti-slip textures.

[0010] By adopting the above technical solution, the anti-slip texture on the outside of the sealing block significantly increases the operating friction, making it easier to manually press the sealing block for maintenance.

[0011] Optionally, the sealing block has a magnetic element at the end away from the spring, and the magnetic element can magnetically engage with the mounting plate.

[0012] By adopting the above technical solution, the magnetic component and the mounting plate can be attracted together, which can temporarily fix the sealing block during maintenance, avoid the spring reset interfering with the operation, and improve the convenience of maintenance.

[0013] Optionally, the hook includes a gripping part and a mounting part; a sliding cavity is provided on the side of the mounting plate opposite to the hook, and the sliding cavity extends along the length direction of the mounting plate; the mounting part is integrally formed with a slider, and the slider is slidably disposed in the sliding cavity.

[0014] By adopting the above technical solution, the cooperation between the slider and the sliding cavity forms a high-precision sliding guide structure, ensuring that the hook moves in a straight line and improving the clamping and positioning accuracy.

[0015] Optionally, the sliding cavity contains a plurality of balls arranged in a linear array along its length.

[0016] By adopting the above technical solution, the linear ball array significantly reduces the sliding friction resistance of the slider, making the claw move more smoothly and reducing wear and operating torque.

[0017] Optionally, one end of the control screw is integrally formed with an extension rod, and the free end of the extension rod is integrally formed with a handheld component; the mounting plate has an isolation hole; the extension rod passes through the isolation hole, so that the handheld component can rotate from the back of the mounting plate to the front of the mounting plate.

[0018] By adopting the above technical solution, the design of the extension rod passing through the isolation hole allows the handheld part to rotate 360° to adjust the operating position, adapting to the ergonomic needs of different installation scenarios.

[0019] In summary, this application includes at least one of the following beneficial technical effects: The combination of the slider and the sliding cavity forms a high-precision sliding guide structure, ensuring that the claw moves in a straight line and improving the clamping and positioning accuracy.

[0020] The cavity and ball guide system further ensure the linearity and smoothness of the claw's movement.

[0021] Long-lasting dustproof maintenance: The spring sealing block automatically seals the cavity, combined with the magnetic temporary fixing function and anti-slip texture, forming an integrated dustproof and maintenance solution to reduce the failure rate. Attached Figure Description

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses a detector for detecting switches. (Refer to...) Figure 1 The detector for the detection switch is implemented through the following embodiment: The overall structure includes a feeding assembly 1, a clamping assembly 2, and a detection assembly 3 located below the clamping assembly 2. The clamping assembly 2 consists of a support rod 4 and a mounting plate 5 horizontally fixed to the top of the support rod 4. A cavity 6 is formed in the middle of the mounting plate 5, and a control screw 7 is rotatably connected to the cavity 6 via a bearing. The control screw 7 has threads (left-handed and right-handed threads) machined at both ends.

[0029] Reference Figure 1 , Figure 2 A hook 8 is slidably connected to each end of the mounting plate 5. Each hook 8 is integrally formed by the gripping part 19 and the mounting part 20. The mounting part 20 is connected to a drive screw 9, and the two drive screws 9 are respectively engaged with the reverse threads at both ends of the control screw 7. When the control screw 7 is rotated, the reverse threads drive the two drive screws 9 to move the hooks 8 synchronously towards or away from each other, thereby adjusting the distance between the two hooks 8.

[0030] Reference Figure 2 , Figure 3 as well as Figure 4 To protect the internal structure of cavity 6, a sliding sealing block 11 is provided at each end of cavity 6. Under the action of spring 10, the sealing block 11 is always pressed against the port of cavity 6 to block dust. The outer surface of the sealing block 11 is provided with an array of anti-slip textures 12 to enhance the operating friction; a magnetic element 13 is embedded at its end. When the sealing block 11 is compressed and retracted, the magnetic element 13 can be attracted and fixed with the metal end face of the mounting plate 5, which is convenient to keep it in the open state during maintenance. The sliding mechanism of the hook 8 is realized through the sliding cavity 14 opened at the bottom of the mounting plate 5: the slider 15 integrally formed by the mounting part 20 is embedded in the sliding cavity 14. Multiple sets of balls 16 are linearly arranged along the length direction in the sliding cavity 14, which significantly reduces the frictional resistance when the slider 15 slides.

[0031] Reference Figure 2 , Figure 3 as well as Figure 4 The operating end of the control screw 7 is designed such that an extension rod 17 extends integrally from one end, and a handheld component 18 is formed at the end of the extension rod 17. An isolation hole is provided at the corresponding position on the mounting plate 5. After the extension rod 17 passes through the isolation hole, the operator can rotate the handheld component 18 from the back to the front of the mounting plate 5, thereby adjusting the distance between the two hooks 8. The detection component 3 is located directly below the hooks 8. When the hooks 8 pick up the switch to be detected and move it above the detection component 3, the detection component 3 will detect the switch. If no abnormality is found in the switch, the switch will move to the discharge port under the action of the hooks 8.

[0032] This application discloses the implementation principle of a detector for detecting switches as follows: the feeding component 1 first transports the switch to be tested to the area below the hook 8; then the hook 8 grabs the switch to be tested and places it on the platform between the feeding component 1 and the detection component 3; then another hook 8 grabs the switch to be tested on the platform and moves it above the detection component 3 for testing and pauses briefly; if there is no problem, the tested switch is transported away by the hook 8.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
