Description

Technical Field

[0001] The utility model relates to the technical field of metal fastener detection, in particular to a detection mechanism for metal fastener production. Background Art

[0002] Metal fasteners are a type of mechanical part used for fastening connections and are extremely widely used. Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, and other industries. They can be found in a variety of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, meters, and supplies. They are the most widely used mechanical foundation components. However, during the production process of metal fasteners, their quality needs to be tested. If the shear force of metal fasteners is not up to standard, it can easily lead to bending and deformation of the metal fasteners, and in severe cases, it can even cause the fasteners to break. Testing the shear force of metal fasteners usually requires the use of a testing agency.

[0003] However, in existing shear force testing of metal fasteners, the metal fastener is usually placed in a testing mechanism. After the test is completed, the tested metal fastener is removed and the next metal fastener to be tested is placed. Removing and placing the metal fasteners takes too much time, resulting in a decrease in the testing speed of the testing mechanism. Therefore, a testing mechanism for metal fastener production is proposed. Utility Model Content

There are several placement plates 9, and the several placement plates 9 are distributed in a circular array. Two placement plates 9 form a group. By setting up several placement plates 9, multiple metal fasteners can be placed, thereby facilitating continuous conveying of metal fasteners, thereby facilitating continuous detection of metal fasteners.A connecting groove 10 is provided inside the placement plate 9, and the rotating conveying assembly includes a U-shaped fixing plate 2, which is fixedly mounted on the lower side wall of the detection table 1.

The driving gear 4 and the connecting gear 5 are both made of metal. When the driving gear 4 drives the rotating shaft 6 to rotate through the connecting gear 5, A deceleration effect is achieved, so that the rotating shaft 6 drives the rotating disk 7 to move slowly, thereby preventing the metal fasteners in the placement plate 9 from being thrown out. The fixed base plate 8 is fixedly installed on the top of the rotating disk 7. Through the setting of the rotating component, it is easy to drive the fixed base plate 8 to move, so that the placement plate 9 drives the metal fasteners to move, thereby facilitating the transportation of the metal fasteners. An L-shaped mounting plate 11 is fixedly provided on the top of the inspection table 1. A pressing component is provided on the top of the L-shaped mounting plate 11 to facilitate applying pressure to the metal fasteners. A moving rod 17 is provided inside the L-shaped mounting plate 11 through the pressing component. A limiting circular plate 18 is fixed on the top of the moving rod 17. The bottom end of the moving rod 17 is fixedly provided with a connecting plate 19, the top of the connecting plate 19 is fixedly provided with a spring 20, and the bottom of the connecting plate 19 is fixedly provided with a clamping plate 21. The longitudinal cross-sections of the placing plate 9 and the clamping plate 21 are both V-shaped. The placing plate 9 and the clamping plate 21 are both made of metal. The arrangement of the placing plate 9 and the clamping plate 21 with a V-shaped longitudinal cross-section facilitates the placement and fixing of metal fasteners of different specifications, thereby facilitating the detection of metal fasteners of different specifications, making the detection mechanism more flexible to use. The servo motor 3 drives the driving gear 4 to rotate, so that the driving gear 4 drives the rotating shaft 6 to rotate through the connecting gear 5, so that the rotating disk 7 drives the fixed base plate 8 to move, and drives the placement plate 9 to move through the fixed base plate 8, so that the placement plate 9 drives the metal fasteners to move, thereby facilitating the continuous delivery of the metal fasteners to the bottom of the pressing assembly, so that the pressing assembly pushes the metal fasteners to apply pressure for detection, and during the movement of the placement plate 9, the placement plate 9 can drive the metal fasteners that have been tested to move out from under the pressing assembly, so that the fasteners can be removed after the detection is completed, thereby facilitating the detection of the metal fasteners, thereby avoiding wasting too much time in picking up and placing the metal fasteners, resulting in a reduction in the detection speed of the detection mechanism, thereby improving the detection speed of the metal fasteners.

[0022] Specifically, the pressing assembly includes a hydraulic push rod 12, which is fixedly mounted on the top of the detection platform 1, a movable plate 13 is fixedly provided at the output end of the hydraulic push rod 12, a movable rod 17 is slidably arranged inside the movable plate 13, and the top of the spring 20 is fixedly mounted on the bottom of the movable plate 13, a pressure sensor 14 is fixedly provided at the bottom of the detection platform 1, a mounting sleeve 15 is provided on the surface of the pressure sensor 14, a pressing head 16 is fixedly installed inside the mounting sleeve 15, the mounting sleeve 15 includes a rear fixing sleeve 151, the rear fixing sleeve 151 is fixedly mounted on the bottom of the movable plate 13, a front fixing sleeve 152 is fixedly provided on the front side of the rear fixing sleeve 151 by bolts, a pressure plate 153 is overlapped inside the front fixing sleeve 152, the pressing head 16 is fixedly mounted on the bottom of the pressure plate 153, and the pressure plate 153 is overlapped with the detection end of the pressure sensor 14. By removing the bolts, the front fixing sleeve 152 can be removed, thereby The pressure sensor 14 can be maintained or replaced, and the damaged lower pressure head 16 can be replaced by removing the pressure plate 153 from the rear fixing sleeve 151. The hydraulic push rod 12 pushes the movable plate 13 to drive the pressure sensor 14 and the mounting sleeve 15 to move downward, and will drive the movable rod 17, the limiting circular plate 18 and the spring 20 to move downward, so that the connecting plate 19 drives the clamping plate 21 to contact the metal fastener, thereby causing the connecting plate 19 to compress the spring 20, so that the lower pressure head 16 contacts the metal fastener and applies pressure to the metal fastener, so that the lower pressure head 16 pushes the pressure plate 153 to apply pressure to the detection end of the pressure sensor 14, and the pressure applied to the metal fastener is detected by the pressure sensor 14, thereby facilitating the application of pressure to the metal fastener, and facilitating the detection of the pressure applied to the metal fastener, thereby facilitating the detection of whether the shear force of the metal fastener meets the standard when the detection pressure is reached.

[0023] The metal fastener production detection mechanism is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0024] During use: place the metal fastener inside the placement plate 9, and drive the output end through the hydraulic push rod 12 to push the movable plate 13 downward, so that the movable plate 13 drives the pressure sensor 14 and the mounting sleeve 15 to move downward, and the movable plate 13 drives the movable rod 17, the limiting circular plate 18 and the spring 20 to move downward, so that the connecting plate 19 drives the clamping plate 21 to move downward, and the clamping plate 21 is inserted into the connecting groove 10, so that the clamping plate 21 contacts the metal fastener, so that the clamping plate 21 pushes the connecting plate 19 to cooperate with the movable plate 13 to compress the spring 20, so that the lower pressure head 16 contacts the metal fastener, and the metal fastener is pressurized by the lower pressure head 16, and the metal fastener gives the lower pressure head 16 a reverse force, so that the lower pressure head 16 pushes the pressure plate 153 applies pressure to the detection end of the pressure sensor 14, and detects the pressure applied to the metal fastener by the pressure sensor 14. If the metal fastener does not bend when the detection pressure is reached, it means that the metal fastener is qualified. If the metal fastener bends, it means that the metal fastener is unqualified. After the detection of a metal fastener is completed, the output end is driven by the servo motor 3 to drive the driving gear 4 to rotate, and the driving gear 4 drives the connecting gear 5 engaged with it to rotate, and drives the rotating shaft 6 to rotate through the connecting gear 5, and drives the rotating disk 7 to rotate through the rotating shaft 6. The rotating disk 7 drives the placement plate 9 to rotate through the fixed bottom plate 8, so that the placement plate 9 drives the metal fastener to move, thereby continuously conveying the metal fastener to the bottom of the pressure head 16.

[0025] To sum up, the detection mechanism for the production of metal fasteners drives the driving gear 4 to rotate through the servo motor 3, so that the driving gear 4 drives the rotating shaft 6 to rotate through the connecting gear 5, so that the rotating disk 7 drives the fixed base plate 8 to move, and drives the placement plate 9 to move through the fixed base plate 8, so that the placement plate 9 drives the metal fasteners to move, thereby facilitating the continuous delivery of the metal fasteners to the bottom of the pressing component, so that the pressing component pushes the metal fasteners to apply pressure for detection, and during the movement of the placement plate 9, the placement plate 9 can drive the metal fasteners that have been inspected to move out from under the pressing component, so that the fasteners can be removed after the inspection is completed, thereby facilitating the inspection of the metal fasteners, thereby avoiding wasting too much time in picking up and placing the metal fasteners, resulting in a reduction in the inspection speed of the detection mechanism, thereby improving the inspection speed of the metal fasteners, which is used to solve the problems raised in the above-mentioned background technology.
