Description

Technical Field

[0001] This utility model relates to the field of riveting equipment technology, and specifically to a quick positioning and feeding mechanism for rivet nuts. Background Technology

[0002] In the field of riveting, some products have polygonal rivet holes, such as hexagons, and rivet nuts are also relatively polygonal. However, in existing automated riveting equipment, the angle of the rivet nut is generally not adjustable, thus failing to meet production needs.

[0003] Therefore, based on the aforementioned shortcomings of existing riveting equipment, it is necessary to improve the existing riveting equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a quick positioning and feeding mechanism for rivet nuts to address the shortcomings of existing technologies. This quick positioning and feeding mechanism for rivet nuts solves the defects of existing riveting equipment, such as the difficulty in adjusting the angle of rivet nuts.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0006] The quick-positioning and feeding mechanism for rivet nuts includes a rivet gun and a fixing component. A movable groove is laterally formed in the middle of the fixing component. A movable component push cylinder is installed at one end of the movable groove, and a support cylinder is installed at the other end. A movable component is housed within the fixing component, and the movable component push cylinder drives the movable component. A discharge groove is longitudinally formed at the bottom of the fixing component, and the discharge groove communicates with the movable groove. The movable component has a through-hole discharge groove and a positioning groove. The positioning groove is a polygonal groove located on one side of the discharge groove. The movable head of the rivet gun is located at the upper end of the discharge groove. The telescopic rod of the support cylinder extends movably into the discharge groove of the movable component.

[0007] Furthermore, a feed plate is installed on the top of the fixing component, and a feed pipe and a connecting pipe are provided on the upper end surface of the feed plate. The feed pipe is connected to the rivet gun. The movable head of the rivet gun moves up and down within the feed pipe to realize the rivet action.

[0008] Furthermore, a limiting strip is formed laterally within the movable groove, and a limiting groove is laterally opened on the side of the movable part, with the limiting strip embedded in the limiting groove.

[0009] Furthermore, the upper end of the movable component has a downward-facing recessed platform, which is used to position the rivet nut.

[0010] Furthermore, the sunken platform has a recessed portion. The head of the rivet nut is positioned within the recessed portion.

[0011] Furthermore, the upper end of the fastener has two holes communicating with the movable groove, which correspond to the feed pipe and connecting pipe of the feed plate, respectively. The rivet nut enters the movable groove through the feed pipe, and the movable head of the rivet gun can pass downward through the movable groove.

[0012] Furthermore, the fastener is rectangular in shape, which facilitates processing.

[0013] Furthermore, the bottom of the fixing component is longitudinally provided with a moving groove, which is connected to the discharge groove and communicates with the movable groove. The moving groove facilitates the movement of the rod of a long rivet nut.

[0014] The beneficial effects of this utility model are as follows: when the rivet nut falls into the movable part, the telescopic rod can extend and abut against the rod of the rivet nut, so that the rod of the rivet nut is pushed into the positioning groove to achieve positioning, thereby quickly realizing the angle adjustment of the rivet nut, which can be used to achieve rapid and automated riveting.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] See Figure 1 —— Figure 7 This utility model relates to a quick-positioning and feeding mechanism for rivet nuts, comprising: a rivet gun 1, a fixed component 2, a movable component pushing cylinder 6, and a supporting cylinder 7. The movable component pushing cylinder 6 and the supporting cylinder 7 are respectively installed at the left and right ends of the fixed component 2. A feeding plate 3 is installed on the top of the fixed component 2. A feeding pipe 4 and a connecting pipe 5 are arranged side-by-side on the upper surface of the feeding plate 3. A plastic tube is connected to the feeding pipe 4 for feeding the rivet nuts. The connecting pipe 5 connects to the rivet gun 1. The movable component pushing cylinder 6 drives the movable component 12.

[0026] See Figure 3 , Figure 4 , Figure 5 The fixing member 2 of this utility model is rectangular in shape. A movable groove 8 is laterally formed in the middle of the fixing member 2. A movable member pushing cylinder 6 is installed at one end of the movable groove 8, and a supporting cylinder 7 is installed at the other end. A limiting strip 11 is formed laterally inside the movable groove 8. A movable member 12 is movably disposed inside the fixing member 2, and the limiting strip 11 limits the movable member 12. Two holes are formed at the upper end of the fixing member 2, communicating with the movable groove 8. These two holes correspond to the feed pipe 4 and connecting pipe 5 of the feed plate 3, respectively. A moving groove 9 and a discharge groove 10 are longitudinally formed at the bottom of the fixing member 2. The moving groove 9 and the discharge groove 10 are connected and communicate with the movable groove 8.

[0027] See Figure 6 , Figure 7 The movable component 12 of this utility model is square. A limiting groove 13 is laterally formed on the side of the movable component 12, and a limiting strip 11 is embedded in the limiting groove 13. The movable component 12 can move laterally along the limiting strip 11. A material dropping groove 14 and a positioning groove 15 are longitudinally formed on the movable component 12, and the material dropping groove 14 and the positioning groove 15 penetrate the movable component 12. The positioning groove 15 is a polygonal groove and is located on one side of the material dropping groove 14. A sunken platform 16 is formed on the upper end of the movable component 12, and the sunken platform 16 has a recessed portion 17.

[0028] The working principle of this utility model is as follows:

[0029] 1. The rivet nut 18 is fed into the feed pipe 4 through the plastic tube and falls downward into the movable groove 8 of the fixing part 2. The movable part 12 is located below the feed pipe 4. The rod of the rivet nut 18 passes into the drop groove 14 of the movable part 12, and the head of the rivet nut 18 falls into the lower recess 17 of the movable part 12.

[0030] 2. The movable part pushes the cylinder 6 to push the movable part 12 forward, and the movable part 12 moves along the limit bar 11 until the movable part 12 is below the connecting pipe 5;

[0031] 3. The telescopic rod of the support cylinder 7 extends, abuts against the rod of the rivet nut 18 and moves along the material drop groove 14 into the positioning groove 15, the head of the rivet nut 18 moves onto the sinking platform 16, and the rod of the hexagonal rivet nut 18 is positioned in conjunction with the hexagonal positioning groove 15, thereby adjusting the angle of the rivet nut 18.

[0032] 4. The movable head of the rivet gun 1 extends downward into the movable groove 8 of the fixing part 2 and acts with the rivet nut 18, so that the rivet nut 18 is screwed into the head of the rivet gun 1, and the head of the rivet nut 18 protrudes from the upper end face of the movable part 12.

[0033] 5. The moving part pushes the cylinder 6 to reset, and the supporting cylinder 7 to reset;
