DETAILED DESCRIPTION

[0022] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0023] See also Figure 2-7 The utility model provides an embodiment: a riveting device, including a support part 1, a guide sleeve 3 slidingly matched with the support part 1, and a push rod 11 slidingly matched with the guide sleeve 3; a positioning pin 12 is also provided under the support part 1, and the guide sleeve 3 is concentrically arranged with the push rod 11, and the push rod 11 is concentrically arranged with the positioning pin 12.

[0024] When the positioning pin 12 is inserted into the pin hole from one side of the workpiece, the push rod 11 contacts the workpiece from the other side, and the push rod 11 is used to push the pin in the guide sleeve 3 into the pin hole. The pin can be riveted into the pin hole; at the same time, the rod-shaped guide sleeve 3 and the rod-shaped push rod 11 cooperate with each other to expand the distance between the user's hand and the workpiece, thereby releasing the riveting space of the workpiece for the user to observe and improve the riveting quality.

[0025] Based on this, the positioning pin 12 is used for positioning, and the push rod 11 is concentrically arranged with the positioning pin 12. Therefore, when the riveting device is riveting the pin, the pin does not need to be supported by hand while ensuring that the pin is smoothly inserted into the pin hole, thereby effectively solving the problem of the hand blocking the line of sight; at the same time, the riveting device has a simple structure, is easy to operate, and is safe, and can smoothly rivet the pin onto a workpiece with a narrow operating space to improve the riveting efficiency of the pin.

[0026] Furthermore, the support part 1 is provided with a connecting piece 9, and the connecting piece 9 is provided with a supporting platform 8 concentric with the support part 1, and the sliding of the guide sleeve 3 is stabilized by the supporting platform 8. In addition, the guide sleeve 3 is supported and guided by the support part 1, and when the user holds the support part 1, the normal operation of the guide sleeve 3 and the ejector rod 11 is not affected. Therefore, the stability of the device during use can be ensured by holding the support part 1, so as to ensure the smooth riveting of the pin.

[0027] In addition, in order to alleviate the contradiction between the field of vision and the reliable assembly of the pins, that is, the pins are not supported by hands, otherwise they are prone to position displacement during the riveting process, resulting in riveting failure; if they are supported by hands, since the pins are small, the hands will block the field of vision, and the knocking tools may easily injure the hands or the pins.

[0028] To this end, the connecting piece 9 is extended downward to approach the workpiece, and the support part 1 can be away from the workpiece, thereby releasing the space of the workpiece riveting position for the user to observe, and at the same time, the support platform 8 is sleeved on the outside of the guide sleeve 3 to ensure that the guide sleeve 3 is stable and does not shake when it is hit, thereby ensuring the stability of the push rod 11 when it works. This prevents the guide sleeve 3 from shaking when it moves, which may cause the pin to fail to be smoothly inserted into the rivet hole.

[0029] At the same time, since the guide sleeve 3 is connected to the locking member 7, and the locking member 7 abuts against the support platform 8, the downward sliding distance of the guide sleeve 3 is limited. Therefore, when the lower end surface of the locking member 7 abuts against the support platform 8, the guide sleeve 3 can be prevented from sliding further downward, and the locking member 7 can be held to cause the guide sleeve 3 to slide upward, thereby facilitating the insertion of the pin into the guide sleeve 3.

[0030] Furthermore, since an elastic member 4 is provided between the facing surfaces of the locking member 7 and the supporting portion 1, and the locking member 7 is urged to press against the supporting platform 8 by the elastic member 4, when the external force of the locking member 7 disappears, the guide sleeve 3 can be urged to move downward, and at this time the guide sleeve 3 can also press against the workpiece when there is no external force; wherein the elastic member 4 is preferably a coil spring, and the locking member 7 is two semicircular clamps, which are clamped on the guide sleeve 3 by inserting bolts along the two semicircular clamps.

[0031] Since a first slider 15 is provided on the outer wall surface of the locking member 7, and the first slider 15 is adaptively connected to the first slide groove 10 provided on the connecting member 9, the first slider 15 is used to slide in the first slide groove 10 to prevent the locking member 7 from driving the guide sleeve 3 to axially rotate.

[0032] On the basis of the above scheme, since the positioning pin 12 is movably connected to the support part 1 through the provided connecting frame 2, the installation and replacement of the connecting frame 2 are simple and convenient; in addition, the connecting frame 2 of corresponding size can be selected according to the diameter of the workpiece to expand the application capability of the device. Specifically, the distance between the center of the positioning pin 12 and the inner wall of the connecting frame 2 is selected to be equal to the radius of the workpiece, so that the device can perform riveting on workpieces of different diameters.

[0033] Furthermore, since the connecting frame 2 is adapted to be connected with the second slider 13 provided at the lower end of the supporting portion 1 through the second slide groove 14, and the fastener passes through the second slide groove 14 and is connected with the second slider 13, the connecting frame 2 is fixed to the supporting portion 1. Therefore, the connecting frame 2 is convenient to disassemble while ensuring reliable installation.

[0034] Since the end of the push rod 11 away from the positioning pin 12 is connected to the provided connector 6, the connector 6 can be used to withstand external impact, thereby reducing damage to the push rod 11 and extending the service life of the device.

[0035] Since the guide sleeve 3 is provided with an arc groove 16 on the side facing the positioning pin 12, the arc groove 16 can be used to contact the rocker shaft to ensure that the guide sleeve 3 can be reliably attached to the rocker shaft, thereby reducing the displacement of the guide sleeve 3 caused by external impact. The guide sleeve 3 is also provided with a force-bearing portion 5 at one end away from the arc groove 16, so before the pin is basically riveted into the pin hole, the force-bearing portion 5 can be used to withstand the impact from the connector 6.

[0036] To sum up, when the user holds the support part 1, the other hand pushes the locking piece 7 to move upward to move the guide sleeve 3 upward, and then installs the pin into the guide sleeve 3, and then the connecting head 6 is connected to the external air hammer, and the air hammer strikes the connecting head 6. At this time, the connecting head 6 pushes the push rod 11 to move, thereby pushing the pin in the guide sleeve 3 into the pin hole, thereby completing the riveting of the pin.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
