Description

Technical Field

[0001] The utility model relates to the field of fastener removal, in particular to a device for automatically discharging broken nuts. Background Art

[0002] Self-locking nuts are a special type of nut widely used in industries such as automotive, aerospace, mechanical engineering, and construction. Self-locking nuts are often installed with Hi-Lok bolts. During installation, an internal hexagonal socket and a socket wrench are usually required. By installing the socket wrench connection hole of the internal hexagonal socket onto the hexagonal connector of the socket wrench, and then aligning the hexagonal cylindrical hole of the internal hexagonal socket with the self-locking nut to be removed, the wrench is rotated to turn the self-locking nut until it is broken off to complete the installation. Since the drawing requires the use of sealant for wet installation of the connecting parts, after repeated installations, excess sealant will remain in the socket. Due to the viscosity of the sealant and the dead point of contact between the broken nut and the inner side of the socket, it is easy to cause jamming problems. When the broken nut gets jammed in the socket during actual installation operations, the solution is to disassemble the wrench and the socket, and use tools such as a drill bit to push out the broken nut at the other opening of the socket, and then reassemble. Currently, on average, 1-2 jamming situations occur for every 10 self-locking nuts broken off. Each time a jamming situation occurs, the installation work needs to be stopped to disassemble and deal with the jammed nut, which is time-consuming and laborious and affects the continuity of work, greatly reducing work efficiency. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a device for automatically discharging broken nuts, which can automatically discharge the broken nuts and improve the continuity of installation.

[0004] The technical solution adopted by the utility model to solve its technical problem is:

[0005] A device for automatically discharging broken nuts, comprising a socket. The socket is a cylinder with a socket wrench connection hole at one end and a nut connection hole at the other end. A pop-up device is provided in the nut connection hole of the socket. The central axis of the pop-up device is parallel to the central axis of the nut connection hole. One end of the pop-up device away from the bottom of the nut connection hole is provided with a pop-up part. When the pop-up device is pressed, the pop-up device will generate a rebound force in the direction opposite to the pressure source, causing the pop-up part to move along the central axis of the nut connection hole.

[0006] Further, the pop-up device is a spring.

[0007] Further, a mounting base plate is fixedly provided in the nut connection hole. The inner surface of the mounting base plate fits with the bottom of the nut connection hole, and the outer surface of the mounting base plate is fixedly connected to one end of the pop-up device close to the bottom of the nut connection hole.

[0008] Further, the nut connection hole of the socket is a hexagonal cylindrical hole.

[0009] Further, the sleeve is a cylinder with a socket wrench connection hole at one end and a nut connection hole at the other end.

[0010] Further, the ejecting part of the ejecting device is a flat plate, and the side wall of the ejecting part fits against the inner wall of the nut connection hole.

[0011] The beneficial effects of the present utility model are as follows:

[0012] For the automatic nut-breaking and discharging device provided by the present utility model, the ejecting device can be made of elastic materials such as rubber or spring, which can quickly generate a restoring force when subjected to pressure, driving the ejecting part to translate outward along the axis of the nut connection hole, so as to automatically push the broken nut out of the sleeve. This device solves the cleaning problem after breaking the nut through an automated method, without the need for additional tools or manual intervention, greatly shortening the operation time, avoiding the cumbersome and time-consuming manual cleaning of the nut, and improving work efficiency.

[0013] At the same time, due to the automatic ejection function of the ejecting device, the need for operators to directly contact the broken nut is reduced, the risk of hand scratches caused by the sharp edges remaining on the broken nut is lowered, and the safety of the operation process is improved.

[0014] The ejecting device adopts a spring structure, and the force-receiving effect is better than that of rubber.

[0015] The mounting base plate is coaxially fixed with the nut connection hole, ensuring the stable support of the ejecting device and the ejecting part. At the same time, the end face of the base away from the ejecting device fits against the bottom of the nut connection hole, which not only ensures the overall structural stability but also makes the movement of the ejecting part more precisely controllable, avoiding deflection or jamming during the ejection process.

[0022] An automatic nut ejection and breaking device includes a sleeve 1. The sleeve 1 is a cylinder with a socket wrench connection hole at one end and a nut connection hole at the other end. It is characterized in that a pop-up device 3 is provided in the nut connection hole of the sleeve 1. The central axis of the pop-up device 3 is parallel to the central axis of the nut connection hole. One end of the pop-up device 3 far from the bottom of the nut connection hole is provided with a pop-up part 2. When the pop-up device 3 is pressed, the pop-up device 3 will generate a rebound force in the direction opposite to the pressure source, causing the pop-up part 2 to move along the central axis of the nut connection hole.

[0023] The pop-up device 3 can be made of elastic materials such as rubber or spring, which can quickly generate a restoring force when subjected to pressure, driving the pop-up part 2 to translate outward along the axis of the nut connection hole, thereby automatically pushing the broken nut out of the inside of the sleeve 1. This device solves the problem of cleaning after the nut is broken in an automated manner, without the need for additional tools or manual intervention, greatly shortening the operation time, avoiding the tediousness and time-consuming of manual cleaning of the nut, and improving work efficiency. At the same time, due to the automatic ejection function of the pop-up device 3, the need for operators to directly contact the broken nut is reduced, and the risk of hand scratches caused by the sharp edges remaining on the broken nut is lowered, improving the safety of the operation process.

[0024] As Figure 1 shown, the pop-up device 3 is a spring. Compared with rubber, the spring has better elasticity and is also more cost-saving. Therefore, the pop-up device 3 is preferably a spring in this solution.

[0025] A mounting base plate 4 is fixedly provided in the nut connection hole. The inner surface of the mounting base plate 4 fits with the bottom of the nut connection hole, and the outer surface of the mounting base plate 4 is fixedly connected to one end of the pop-up device 3 close to the bottom of the nut connection hole.

[0026] The mounting base plate 4 is coaxially fixed with the nut connection hole, ensuring stable support for the ejection device 3 and the ejection part 2. At the same time, the end face of the base away from the ejection device 3 fits with the bottom of the nut connection hole, which not only ensures the overall structural stability but also makes the movement of the ejection part 2 more accurate and controllable, avoiding deflection or jamming during the ejection process.

[0027] As Figure 1 shown, the nut connection hole of the sleeve 1 is a hexagonal cylindrical hole.

[0028] The hexagonal cylindrical hole enables the device to be applicable to nuts of different specifications and shapes, improving the versatility and application range of the device.

[0029] Furthermore, the sleeve 1 is a cylinder with a socket wrench connection hole at one end and a nut connection hole at the other end.

[0030] In this solution, the sleeve 1 can also be a quadrangular prism with a socket wrench connection hole at one end and a nut connection hole at the other end. However, considering processing convenience and safety during the working process, a cylinder without edges and corners is preferred.

[0031] Furthermore, the ejection part 2 of the ejection device 3 is a flat plate, and the side wall of the ejection part 2 fits with the inner wall of the nut connection hole.

[0032] The ejection part 2 being a flat plate can make the broken nut bear force evenly when ejecting the broken nut. The side wall of the ejection part 2 fitting with the inner wall of the nut connection hole can ensure the smooth operation of the ejection part 2 without tilting or jamming of the nut.

[0033] For the automatic nut-breaking and ejecting device provided by the present utility model, its preparation process and surface treatment method are not limited. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
