Description

Technical Field

[0001] The utility model relates to the technical field of friction plug riveting welding rotating steel rivet structure, in particular to a rotating steel rivet structure for friction plug riveting welding. Background Art

[0002] Rotating steel rivets requires placing two metal parts together and inserting a rivet (also called a rivet stud) between the two parts. The rivet is quickly spun by rotating the spindle of the riveting machine. The spinning machine applies a certain amount of pressure, which creates friction between the rivet and the two parts.

[0003] When the existing rivets are welded with other parts, the rivets are rotated to weld the rivets with other parts, so that the welding positions are inconsistent each time, resulting in the need to adjust the positions of the parts according to the height of the rivet welding, thereby increasing the work after welding and affecting work efficiency. Utility Model Content

[0004] In order to overcome the problem that when the existing rivet is welded with other parts, the rivet is welded with the other parts by rotating, so that the position of each welding is inconsistent, resulting in the need to adjust the position of the parts according to the height of the rivet welding, thereby increasing the work after welding and affecting the insufficient work efficiency, the embodiment of the present application provides a rotating steel rivet structure for friction plug riveting. When the friction plug at one end of the rivet body is bonded with the copper plate to be welded, the nut at one end of the rivet body is connected to the tightening device. At this time, the rivet body is rotated in the opposite direction by starting the tightening device. Since the threaded strip on the outside of the rivet body does not match the thread groove in the opposite direction, when the rivet body is rotated in the opposite direction, idling is formed to rotate the friction plug. Since the friction plug has a low melting point, the friction plug and the bonded copper plate are rotated and rubbed, so that the temperature of the friction plug continues to increase. When the melting point is reached, the friction plug melts, and the rivet body is welded with the bonded copper plate, so that the rivet body is welded to the required instrument, ensuring that the instrument is fixed more stably.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0006] A rotating steel rivet structure for friction plug riveting, comprising a rivet body and a sleeve, wherein the sleeve is arranged outside the rivet body and is used to fix the device;

[0007] Among them, one end of the rivet body is fixedly connected with a friction plug for softening during friction, and the matching groove provided inside the sleeve makes the rivet body more stable when rotating, which is used for the rotation of the rivet body.

[0008] In a possible implementation, the sleeve is integrally formed with a thread groove, and the thread groove is embedded in the interior of the matching groove and fits therewith, so that the rivet body needs to enter the interior of the sleeve by rotation.

[0009] In a possible implementation, there are no thread grooves embedded on both sides of the interior of the matching groove, and they are arranged in the blank space at the top of the matching groove, so that the rivet body first extends into the blank space of the matching groove and then enters the interior of the matching groove through forward rotation.

[0010] In a possible implementation, a thread strip is embedded in the middle of the rivet body for rotationally cooperating with the thread groove, and the thread strip is threadedly connected to the thread groove, so that when the rivet body is reversed, it cannot cooperate with the thread groove.

[0011] In one possible implementation, a limiting tube is fixedly connected to the outer side of the top of the sleeve to limit the distance between the sleeve and the rivet body. The bottom of the limiting tube is located inside the sleeve, so that when the rivet body enters the sleeve, the limiting tube prevents the rivet body from contacting the sleeve.

[0012] In one possible implementation, one end of the rivet body extends into the sleeve, and the limiting tube limits the position of the rivet body so that the rivet body does not contact the sleeve, thereby preventing the rivet body from causing friction on the top of the sleeve when rotating, thereby preventing damage to the sleeve.

[0013] In one possible implementation, a nut is fixedly connected to the top of the rivet body for controlling the rotation of the rivet body, an anti-slip slope is provided around the outside of the nut to better cooperate with the tightening device, and a connecting groove is provided inside the nut to cooperate with the tightening device.

[0014] In summary, the utility model includes at least one of the following beneficial technical effects:

[0015] 1. Start the tightening equipment and rotate the rivet body in the opposite direction. Since the thread strip on the outside of the rivet body does not match the thread groove in the opposite direction, the rivet body rotates in the opposite direction, which causes idling and rotates the friction plug. Since the friction plug has a low melting point, the friction plug rotates and rubs against the copper plate, causing the temperature of the friction plug to continue to rise. When the melting point is reached, the friction plug melts and welds the rivet body to the copper plate, thereby welding the rivet body to the required instrument, ensuring that the instrument is fixed more stably.

[0016] 2. First, insert the rivet body into the sleeve. Since a threaded strip is embedded in the middle of the rivet body, it is threadedly connected with the thread groove inside the sleeve. The rivet body can be inserted into the sleeve by rotating it, so that the rivet body and the sleeve become one. Then the integrated sleeve is inserted into the device that needs to be fixed. Since a limiting tube is fixedly connected to the outside of one end of the sleeve, the nut at one end of the rivet body is moved away from one end of the sleeve through the limiting tube after the rivet body is inserted.

[0022] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0023] Embodiment 1:

[0024] This embodiment introduces a specific structure of a rotating steel rivet structure for friction plug riveting. Figure 1-Figure 4As shown, it includes a rivet body 1 and a sleeve 2. The sleeve 2 is arranged outside the rivet body 1 for fixing the device. One end of the rivet body 1 is fixedly connected with a friction plug 3. When it is necessary to weld the stable device outside the rivet body 1 with other devices, the friction plug 3 at one end is driven to rotate by rotating the rivet body 1. The friction plug 3 is softened by high-speed rotation to generate high temperature, and the softened and fitted device is fixed. When the temperature cools down, the friction plug 3 is welded with the fitted device to complete the fixation of the device and the device. Due to the matching groove 4 provided inside the sleeve 2, the rivet body 1 is more stable when rotating, and the rivet body 1 is in idling when rotating in the opposite direction. When the friction plug 3 is welded with other devices, the rivet body 1 is moved forward to cooperate with the matching groove 4 to compress the inside. The sleeve 2 is integrally formed with a thread groove 5, and the thread groove 5 is embedded in the inside of the matching groove 4 and fits with it, so that the rivet body 1 needs to enter the inside of the sleeve 2 by rotation, and the welding work can be operated after entering the inside.

[0025] Among them, there are no threaded grooves 5 embedded on both sides of the interior of the matching groove 4, and they are arranged in the blank space at the top of the matching groove 4, so that the rivet body 1 first extends into the blank space of the matching groove 4, and then enters the interior of the matching groove 4 through forward rotation, thereby ensuring that when the rivet body 1 needs to enter the interior of the matching groove 4, the distance that the rivet body 1 enters can be better controlled.

[0026] Secondly, a thread strip 6 is embedded in the middle position of the rivet body 1, which is used to rotate with the thread groove 5, and when the rivet body 1 rotates forward, it enters into the sleeve 2. When the rivet body 1 rotates in the reverse direction, the rivet body 1 forms an idle rotation. Since the thread strip 6 is threadedly connected with the thread groove 5, when the rivet body 1 is reversed, it cannot cooperate with the thread groove 5 and forms an idle rotation, thereby performing rotation welding. Since a limiting tube 7 is fixedly connected to the outer side of the top of the sleeve 2 to limit the distance between the sleeve 2 and the rivet body 1, and since the bottom of the limiting tube 7 is located inside the sleeve 2, when the rivet body 1 enters into the sleeve 2, the limiting tube 7 prevents the rivet body 1 from contacting the sleeve 2;

[0027] Furthermore, one end of the rivet body 1 extends into the sleeve 2, and the limiting tube 7 limits the position where the rivet body 1 extends, so that the rivet body 1 will not contact the sleeve 2, avoiding friction on the top of the sleeve 2 when the rivet body 1 rotates, thereby damaging the sleeve 2. Since a nut 8 is fixedly connected to the top of the rivet body 1, when the rivet body 1 needs to be rotated, it is connected to one end of the tightening device to control the rotation of the rivet body 1 by rotation. An anti-slip slope 9 is provided around the outside of the nut 8, so that after being connected with the tightening device, the rotation is more stable and can be better stressed during rotation. A connecting groove 10 is provided inside the nut 8 to cooperate with the tightening device. When the rivet body 1 needs to be rotated, it only needs to be rotated by tightening the device.

[0028] By adopting the above technical solution:

[0029] In the above design, when the friction plug 3 at one end of the rivet body 1 is fitted with the copper plate to be welded, the nut 8 at one end of the rivet body 1 is connected to the tightening device. At this time, the rivet body 1 is rotated in the opposite direction by starting the tightening device. Since the threaded strip 6 on the outside of the rivet body 1 does not cooperate with the threaded groove 5 in the opposite direction, when the rivet body 1 is rotated in the opposite direction, idling is formed to rotate the friction plug 3. Since the friction plug 3 has a low melting point, the friction plug 3 rotates and rubs against the fitted copper plate, so that the temperature of the friction plug 3 continues to increase. When the melting point is reached, the friction plug 3 melts, and the rivet body 1 is welded to the fitted copper plate, so that the rivet body 1 is welded to the required instrument, ensuring that the instrument is fixed more stably.

[0030] Embodiment 2:

[0031] Based on Example 1, this example introduces the specific structure of the rivet body 1. A threaded strip 6 is embedded in the middle of the rivet body 1. The threaded strip 6 is threadedly connected to the thread groove 5. A limiting tube 7 is fixedly connected to the outer side of the top of the sleeve 2. The bottom of the limiting tube 7 is located inside the sleeve 2.

[0032] Among them, the threaded strip 6 in the middle of the rivet body 1 will not contact the threaded groove 5 inside the sleeve 2 because the friction plug 3 is not as wide as the rivet body 1, thereby avoiding damage to the friction plug 3. When the temperature is increased by rotation later, the damaged area is heated unevenly, resulting in a high probability of cracks in the weld after welding, thereby affecting the fixation of the weld.

[0033] By adopting the above technical solution:

[0034] When the rivet body 1 needs to be inserted into the connection port, the rivet body 1 is first inserted into the sleeve 2. Since a threaded strip 6 is embedded in the middle of the rivet body 1, it is threadedly connected with the thread groove 5 inside the sleeve 2. The rivet body 1 is inserted into the sleeve 2 by rotating it, so that the rivet body 1 and the sleeve 2 become one. Then the integrated sleeve 2 is inserted into the device that needs to be fixed. Since a limiting tube 7 is fixedly connected to the outside of one end of the sleeve 2, the nut 8 at one end of the rivet body 1 is moved away from one end of the sleeve 2 through the limiting tube 7 after the rivet body 1 is inserted.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
