Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically a pneumatic multi-point clamping mechanism. Background Technology

[0002] A heating wire is an electrothermal element that generates heat by passing an electric current through it. Its working principle is based on Joule's law, which states that when an electric current passes through a conductor, the conductor experiences resistance, and the heat generated by this resistance is proportional to the square of the current flowing through the conductor. Specifically, when an electric current passes through the heating wire, the current flows through its surface conductor. After passing through a certain resistance, the electrical energy is converted into heat energy, thus raising the wire's temperature. As the wire temperature rises, its surface radiates thermal radiation, heating surrounding objects. Heating wires are core components in many electrical devices such as electronic cigarettes, hair dryers, and space heaters. During the production process, heating wires are typically clamped before being tested for electrical conductivity.

[0003] Currently, the heating wire testing process often requires personnel to use clamps to hold and fix the wire in place, manually connect its circuit, and then perform power-on testing. Because the overall operation is cumbersome and often takes a lot of time, it seriously affects the efficiency of heating wire testing and production. Utility Model Content

[0023] Please see Figures 1-4 As shown, this utility model provides a pneumatic multi-point clamping mechanism, including a support platform 1 and a cylinder 3. A detection platform 8 is fixedly connected to the middle of the top of the outer surface of the support platform 1. A fixing plate 9 is fixedly connected to the bottom of the inner cavity of the detection platform 8. An electromagnet 12 is fixedly installed on the top of the fixing plate 9. A positioning seat 16 is fixedly connected to the top of the outer surface of the detection platform 8. A receiving through hole 15 is opened on the top of the detection platform 8. A moving plate 13 is movably connected to the surface of the receiving through hole 15. A conductive contact rod 17 is fixedly connected to the upper left side of the moving plate 13. An iron block 11 is fixedly connected to the lower left side of the moving plate 13. A horizontal plate 4 is fixedly installed at the output end of the cylinder 3. A pressure rod 20 is fixedly connected to the bottom of the horizontal plate 4. A magnetic control switch 18 is fixedly installed at the middle of the left side of the pressure rod 20. A limiting sleeve 5 is movably connected to the lower end of the pressure rod 20. A support spring 22 is fixedly connected between the bottom of the inner cavity of the limiting sleeve 5 and the bottom of the pressure rod 20. A magnetic plate 19 is fixedly connected to the left side of the inner cavity of the limiting sleeve 5.

[0024] In this technical solution, the positioning seat 16 supports multiple heating wire assemblies that require power-on testing. The cylinder 3, horizontal plate 4, pressure rod 20, limiting sleeve 5, and support spring 22 effectively clamp and fix the heating wire assemblies, preventing them from shifting during subsequent testing. Furthermore, the coordinated action of the pressure rod 20, magnetic switch 18, magnetic plate 19, electromagnet 12, iron block 11, moving plate 13, and conductive contact rod 17 allows for simultaneous clamping and fixing while powering on the heating wire assemblies is being tested. The overall operation is convenient and quick, achieving both clamping and power-on testing of multiple heating wire assemblies, improving production and testing efficiency, and facilitating user operation.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-4As shown, a limiting groove 23 is provided on the right side of the inner cavity of the limiting sleeve 5. A limiting block 21 is fixedly connected to the lower right end of the pressure rod 20. The surface of the limiting block 21 is movably connected to the surface of the limiting groove 23. A positioning groove 25 is provided on the top of the positioning seat 16. Positioning blocks 24 are fixedly connected to both ends of the top of the positioning seat 16. A fixing frame 6 is fixedly connected between the two ends of the top of the outer surface of the support platform 1. The surface of the cylinder 3 is fixedly installed at the middle of the top of the fixing frame 6. Guide slide rods 7 are fixedly connected between the two ends of the top of the inner cavity of the fixing frame 6 and the two ends of the top of the outer surface of the detection platform 8. The surface of the horizontal plate 4 is movably connected to the surface of the guide slide rod 7. A guide crossbar 14 is fixedly connected to the surface of the through hole 15. The upper end of the moving plate 13 is movably connected to the surface of the guide crossbar 14. A return spring 10 is fixedly connected to the lower left end of the moving plate 13 and below the iron block 11. The left side of the return spring 10 is fixedly connected to the right side of the fixing plate 9. Rubber bases 2 are fixedly connected to all four sides of the bottom of the outer surface of the support platform 1.

[0027] In this technical solution, the limiting groove 23 and the limiting block 21 are used to limit and guide the limiting sleeve 5 and the pressure rod 20, preventing misalignment between the magnetic plate 19 and the magnetic control switch 18 due to rotation between the limiting sleeve 5 and the pressure rod 20. The positioning groove 25 and the positioning block 24 are used to position the heating wire assembly and the positioning seat 16, preventing displacement of the heating wire assembly during placement. The fixing bracket 6 is used to support and fix the cylinder 3. The guide slide rod 7 is used to guide the horizontal plate 4. To prevent the horizontal plate 4 from rotating or tilting during movement, the guide bar 14 guides the moving plate 13, preventing it from tilting. The reset spring 10 is compressed as the moving plate 13 moves to the left, creating tension on the plate. This allows the reset spring 10 to push the moving plate 13 back to the right when the electromagnet 12 stops working. The rubber base 2 supports the bottom of the support platform 1.

[0028] The working principle of this utility model is as follows: The positioning seat 16 supports multiple heating wire assemblies requiring power-on testing. By extending the control cylinder 3, the horizontal plate 4 moves downwards. The movement of the horizontal plate 4 causes the pressure rod 20 and the limiting sleeve 5 to move, allowing the limiting sleeve 5 to contact the top of the heating wire assembly. Continuous movement compresses the support spring 22, causing the limiting sleeve 5 to fit tightly against the top of the heating wire assembly, effectively clamping and fixing the heating wire assembly. This prevents the heating wire assembly from shifting during subsequent testing. Furthermore, the compression of the support spring 22 by the moving pressure rod 20 ensures... The magnetic switch 18 is moved, causing it to be positioned to the right of the magnetic plate 19. Under the magnetic force of the magnetic plate 19, the contacts inside the magnetic switch 18 are attracted and closed, thus connecting the circuit of the electromagnet 12 and generating magnetic force. Under the action of the magnetic force, the iron block 11, the moving plate 13, and the conductive contact rod 17 are attracted and moved to the left. This causes the conductive contact rod 17 to make contact with the circuit contacts on the heating wire assembly, thereby enabling effective energization testing of the heating wire assembly. The overall operation is convenient and quick, achieving the effect of clamping and fixing multiple sets of heating wire assemblies and energizing them, improving the efficiency of production and testing operations, and facilitating personnel use.
