Abstract
Description
Technical Field
[0001] This utility model relates to the field of product testing and sorting technology, and in particular to a hardness testing and sorting device. Background Technology
[0002] In the fields of machinery manufacturing and quality inspection, quality control of various products is crucial, especially hardness testing of metal products, which directly affects product performance, service life, and suitability for various applications. With the continuous expansion of industrial production scale and increasingly stringent product quality requirements, hardness testing and sorting technology is also constantly evolving. Precise and efficient hardness testing and sorting can effectively screen out qualified products, reduce the influx of substandard products into the market, improve enterprise production efficiency and reputation, and drive the entire manufacturing industry towards high-quality development. At the same time, advanced testing and sorting technologies can also reduce production costs, increase the degree of automation, and lay the foundation for intelligent manufacturing in the Industry 4.0 era.
[0003] In the past, the traditional method for hardness testing and sorting of cylindrical metal products mainly relied on ventilation devices to achieve the product screening action. This ventilation method generally uses a complex air circuit system to drive the movement of related components by utilizing changes in air pressure, thereby controlling the product's descent and sorting process.
[0004] Traditional hardness testing and sorting requires air circulation, which not only increases the complexity and cost of the equipment but also makes the operation cumbersome. Air circulation systems often require specialized air source equipment, pipelines, and valves, making maintenance difficult and prone to leaks, affecting the accuracy and stability of the testing and sorting. In contrast, existing technologies cannot meet the demand for both simple and efficient hardness testing and sorting. Utility Model Content
[0005] This application provides a hardness testing and sorting device, which facilitates simple and efficient hardness testing and sorting of products.
[0006] This application provides a hardness testing and sorting device, which adopts the following technical solution:
[0007] A hardness testing and sorting device includes a device body with a feed inlet and a sensing device inside the feed inlet. The device body also includes a first sorting component and a second sorting component. The sensing device detects products and triggers the on / off state of the ferrite cores of the first and second sorting components. The first sorting component opens a channel to allow the product to fall after sensing it, and the second sorting component filters the products, separating qualified and unqualified products.
[0008] By adopting the above technical solution, the present invention designs a hardness detection and sorting device. When in use, the device can be used simply by being powered on without the need for air supply. It can detect the hardness of cylindrical metal products, and uses a sensing device to detect the product and trigger the first and second sorting components to switch on and off the power, thereby opening the channel to allow the product to fall and screening out qualified and unqualified products.
[0009] Preferably, the first sorting component includes a first ferrule, a first coil, and a first rotating rod rotatably connected to the end of the first ferrule. A first rotating shaft is connected to the first rotating rod, and a first actuating plate is connected to the outside of the first rotating shaft. A first lever is mounted on the first actuating plate, and a slider is abutted at the end of the first actuating plate. The slider can slide at the feed inlet, and when it slides to the end, the product falls down. A first return spring is provided on one side of the slider, and the first return spring causes the slider to slide to the initial segment.
[0010] By adopting the above technical solution, when in use, the sensing device detects the product and triggers the first ferrule to switch on and off. When the first ferrule is energized, it attracts and drives the first rotating rod, the first rotating shaft, the first actuating plate, and the first lever to move, pushing the slider to slide to the end of the feed inlet so that the product falls. When the power is off, the first reset spring causes the slider to slide to the initial section to complete the reset, thus realizing the product falling control.
[0011] Preferably, the second sorting component includes a second ferrule, a second coil, and a second rotating rod rotatably connected to the end of the second ferrule. A second rotating shaft is connected to the second rotating rod, and a second actuating plate is connected to the outside of the second rotating shaft. A second lever is installed on the second actuating plate, and the second actuating plate sorts the products by blocking their positions.
[0012] By adopting the above technical solution, during use, the sensing device detects the on / off state of the product triggering the second pin and the second coil, thereby driving the second rotating rod, the second rotating shaft, the second actuating plate, and the second lever to move. The second actuating plate can screen products by blocking their positions, distinguishing between qualified and unqualified products.
[0013] Preferably, a second return spring is provided on the outer side of the second rotating shaft, and the second return spring is used to reset the second toggle plate.
[0014] By adopting the above technical solution, during use, the second sorting component controls the power supply of the second ferrule based on whether the product is qualified or not, thereby controlling the action of the second lever for screening; the second return spring (torsion spring) set on the outside of the second rotating shaft can reset the second lever plate, ensuring the continuous and stable operation of the device and realizing the screening and separation of qualified and unqualified products.
[0015] Preferably, bearings are provided between the first rotating shaft and the first actuating plate, and between the second rotating shaft and the second actuating plate.
[0016] By adopting the above technical solution, the bearings installed between the first rotating shaft and the first actuating plate, and between the second rotating shaft and the second actuating plate, can reduce the frictional resistance during rotation, making the rotation of the first actuating plate and the second actuating plate smoother.
[0017] Preferably, the first return spring is a compression spring and the second return spring is a torsion spring.
[0018] By adopting the above technical solution, when in use, the compression spring is used as the first reset spring. When the electromagnet is not energized, the pushing force of the ferrite is less than that of the compression spring, which allows the slider of the first sorting component to slide to the initial section, thereby resetting the first lever and other components. The torsion spring is used as the second reset spring, which allows the second actuating plate of the second sorting component to reset, ensuring the normal cyclic operation of the entire hardness detection and sorting device.
[0019] Preferably, it also includes a first export channel and a second export channel, wherein the first export channel is used to receive defective products and the second export channel is used to receive qualified products.
[0020] By adopting the above technical solution, when in use, the first export channel and the second export channel are set up to receive unqualified products and qualified products respectively, which can realize the classification and export of products of different quality, and facilitate the separate processing of qualified and unqualified products in the future.
[0021] Preferably, the device body is also provided with a fan for ventilation.
[0022] By adopting the above technical solution, a fan is installed inside the hardness testing and sorting device for ventilation during use, which can ensure air circulation inside the device and guarantee stable operation of the device.
[0023] In summary, this application has the following beneficial effects:
[0024] 1. The present invention relates to a hardness testing and sorting device that does not require air supply and can be used simply by connecting to electricity, thus avoiding the complexity and cost associated with an air supply system and making operation simpler.
[0025] 2. The present invention provides a hardness testing and sorting device that triggers the power-on / off state of the ferrite cores of the first and second sorting components through a sensing device, thereby enabling hardness testing and sorting of cylindrical metal products and accurately and efficiently screening out qualified and unqualified products.
[0026] 3. The present invention provides a hardness testing and sorting device in which the first sorting component and the second sorting component are reset by compression spring and torsion spring respectively, ensuring the continuous and stable operation of the equipment, reducing the occurrence of failures, and improving the accuracy and stability of testing and sorting.

It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0033] This utility model discloses a hardness testing and sorting device, such as... Figures 1 to 4As shown, the device includes a main body 1, a feed inlet 2, a sensing device 3, a first sorting component 4, a second sorting component 5, a first outlet channel 7, a second outlet channel 8, and a fan 9. The feed inlet 2 is located on the main body 1, and the sensing device 3 is installed inside the feed inlet 2. The sensing device 3 is a photoelectric sensor, which is not described in detail in this specification. The first sorting component 4 and the second sorting component 5 are installed inside the main body 1. The sensing device 3 detects products and triggers the on / off state of the pins of the first and second sorting components 4 and 5. The first sorting component 4 opens the channel to allow the product to fall after sensing the product. The second sorting component 5 is used to screen the products, separating qualified and unqualified products. The first outlet channel 7 is used to receive unqualified products, and the second outlet channel 8 is used to receive qualified products. The main body 1 also includes a fan 9 for ventilation. This structure enables the detection and sorting of the hardness of cylindrical metal products without the need for ventilation, simplifying the equipment structure and operation process, and improving the accuracy and stability of detection and sorting.
[0034] Specifically, the first sorting component 4 includes a first ferrule 41, a first coil 42, and a first rotating rod 43 rotatably connected to the end of the first ferrule 41. The first ferrule 41 is typically made of a metal material with good magnetic permeability, and the first coil 42 is generally made of copper wire, as copper has good electrical conductivity and can efficiently generate a magnetic field. The first rotating rod 43 is generally a metal rod, one end of which is rotatably connected to the end of the first ferrule 41 via a pin, facilitating the rotation of the first rotating rod 43 when the first ferrule 41 is engaged or disengaged. A first rotating shaft 44 is connected to the first rotating rod 43, which is generally made of stainless steel, possessing good strength and corrosion resistance. The first rotating shaft 44 is connected to the first rotating rod 43 via a key connection or interference fit to ensure synchronous rotation of both. A first actuating plate 45 is connected to the outer side of the first rotating shaft 44. A first lever 46 is mounted on the first actuating plate 45. The first lever 46 is generally cylindrical and can be made of aluminum alloy, which is lightweight and strong enough. The first lever 46 is mounted on the first actuating plate 45 by threaded connection or snap-fit connection. A slider 47 abuts against the end of the first actuating plate 45. The slider 47 has good wear resistance and self-lubricating properties and can also be made of polytetrafluoroethylene. The slider 47 can slide at the feed inlet 2. When it slides to the end, the product falls down. A first return spring 48 is provided on one side of the slider 47. The first return spring 48 is a compression spring. When the first jack 41 is energized and attracted, the first rotating rod 43 rotates, driving the first rotating shaft 44, the first actuating plate 45 and the first lever 46 to move. The first actuating plate 45 pushes the slider 47 to slide and open the channel to allow the product to fall. When the first jack 41 is de-energized, the spring force pushes the slider 47 back to the initial position.
[0035] Specifically, the second sorting component 5 includes a second ferrule 51, a second coil 52, and a second rotating rod 53 rotatably connected to the end of the second ferrule 51. The second ferrule 51 is similar to the first ferrule 41, and is made of a material with good magnetic conductivity. The second coil 52 is also wound with copper wire. The connection method between the second rotating rod 53 and the second ferrule 51 is the same as that between the first rotating rod 43 and the first ferrule 41. A second rotating shaft 54 is connected to the second rotating rod 53. The second rotating shaft 54 is the same as the first rotating shaft 44. A second actuating plate 55 is connected to the outside of the second rotating shaft 54, and the connection method is similar to that between the first rotating shaft 44 and the first actuating plate 45. A second lever 56 is installed on the second actuating plate 55, and the structure and material of the second lever 56 are similar to those of the first lever 46. The second actuating plate 55 sorts products by blocking their positions. A second return spring 57, which is a torsion spring, is provided on the outside of the second rotating shaft 54. When the product is defective, the second jack 51 remains energized, the second actuating plate 55 remains in the same position, and the product enters the first outlet channel 7; when the product is qualified, the second jack 51 is de-energized and falls, which drives the second actuating plate 55 and the second lever 56 to move, and the product enters the second outlet channel 8. Then the torsion spring resets the second actuating plate 55.
[0036] Bearings 6 are provided between the first rotating shaft 44 and the first actuating plate 45, and between the second rotating shaft 54 and the second actuating plate 55. The bearings 6 are generally deep groove ball bearings 6, which can reduce frictional resistance during rotation and ensure smooth rotation. Angular contact ball bearings 6 can also be used instead.
[0037] Working Principle: This hardness testing and sorting device detects products through the sensing device 3, triggering the energization and de-energization of the electromagnets in the first sorting component 4 and the second sorting component 5. The product is then dropped and sorted using the principle of electromagnet attraction and spring reset. Compared to traditional ventilated testing and sorting devices, this method eliminates the need for a complex pneumatic system, reducing equipment complexity and cost, lowering maintenance difficulty, avoiding malfunctions such as air leaks, and improving the accuracy and stability of testing and sorting. It better meets the needs of modern industrial production for simple and efficient hardness testing and sorting. Simultaneously, the fan 9 provides ventilation and heat dissipation inside the device, extending its service life.
[0038] 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.
