TECHNICAL FIELD

[0001] The utility model belongs to the technical field of equipment for automobile parts machining, especially a core pulling and riveting device facilitating feeding of a glue coating part into a material cavity. BACKGROUND

[0002] The rivet drawing process is a commonly used process in automobile part manufacturing, which is convenient to operate and has strong stability. There are many parts with assembly relationship in the aluminum profile cavity. In order to ensure the sealing property of the profile, a positioning sheet is often used between the screw cap of the rivet nut and the rivet drawing pre-hole of the profile. The positioning sheet is coated with structural glue. After rivet drawing, the structural glue forms a seal between the pre-hole and the rivet nut. At present, the positioning sheet is matched with the rivet nut by hand, and then they are put into the cavity together. There is no accurate positioning, and the operation is difficult and unstable. If there is structural glue in the cavity, the structural glue may be scratched with the inner cavity of the aluminum profile when the part is fed into the cavity, which affects the sealing property of the glue coating. At the same time, the existing hand-held tool has low automation, no accurate positioning, and is easy to scratch the glue coating, which affects the assembly quality. In addition, the operation is time-consuming and laborious, and assembly loss is easy to occur. SUMMARY

[0016] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention.

[0017] like Figures 1 to 4 As shown, the utility model includes a frame 1, a clamp 2, a feeding cylinder 3, a lifting cylinder 4 and an avoidance mechanism. The clamp 2 is arranged above the frame 1. The cylinder barrel of the feeding cylinder 3 is fixed on the frame 1, and a movable frame 31 is provided at the end of the cylinder rod. The avoidance mechanism is installed on the movable frame 31. The lifting cylinder 4 is connected to the avoidance mechanism. The cylinder rod of the lifting cylinder 4 is connected to a feeding tool. After the rivet nut and the glued positioning sheet are assembled, they are placed on the feeding tool as a workpiece. The lifting cylinder 4 drives the feeding tool to rise and fall to the height of the cavity, and then the feeding cylinder 3 sends the feeding tool into the cavity. Then the lifting cylinder 4 continues to rise to press the workpiece against the cavity, and the rivet nut extends from the pores of the cavity for subsequent riveting work. The feeding tooling includes a plurality of parallel feeding rods 5, each end of which is provided with a limiting groove 6. The thickness of the feeding rod 5 is less than the height of the cavity. The limiting groove 6 includes a rivet nut limiting hole 7 and a positioning material limiting hole. Both the rivet nut limiting hole and the positioning material limiting hole are blind holes. The rivet nut limiting hole 7 is located at both ends of the positioning material limiting hole 8. The avoidance mechanism facilitates the return of the workpiece after the anchor is pulled.

[0018] To secure the profile to the frame 1, the fixture 2 includes a support rod 9, a telescopic cylinder 10, and a pressure rod 11. The telescopic cylinder 10 and support rod 9 are longitudinally arranged on the frame 1. Baffles 91 are provided on both sides of the top of the support rod 9. The pressure rod 11 is placed on top of the support rod 9 and located between the baffles 91. One end of the pressure rod 11 is hinged to the telescopic cylinder 10, and the other end is a pressure piece end. The shape of the pressure piece end matches the shape of the workpiece to be processed. The telescopic cylinder 10 is extended and retracted to press the pressure rod 11 onto the profile.

[0019] In order to ensure that the workpiece can be accurately combined with the cavity, and the pull rivet nut extends out of the prefabricated hole, the middle part of the limiting groove 6 is further provided with a fine positioning groove, the middle part of the fine positioning groove is provided with a fine positioning pin 12, the fine positioning pin 12 is slightly lower than the bottom of the positioning material limiting hole 8, the positioning material piece is provided with a positioning hole, and the fine positioning pin 12 is matched with the positioning hole of the positioning material piece. After the fine positioning pin 12 is inserted into the positioning hole, it indicates that the workpiece is installed in the position of the feeding rod 5, the workpiece is sent into the cavity through the feeding cylinder 3 contraction, and then the lifting cylinder 4 is lifted, so that the workpiece can be combined with the cavity, and the pull rivet nut leaks out of the prefabricated hole of the profile.

[0020] Since the nut of the pull rivet nut is long, in order to prevent the nut from being stuck in the pull rivet nut limiting hole 7 and affecting the withdrawal of the feeding rod 5 from the cavity, an avoiding mechanism is arranged, the avoiding mechanism comprises an avoiding cylinder and an avoiding groove, the avoiding groove is arranged on the feeding rod 5, the avoiding groove is located on the side of the pull rivet nut limiting hole 7 and the positioning material limiting hole and is communicated, and the bottom end of the avoiding groove is in an open shape. The avoiding cylinder is arranged transversely, the cylinder barrel of the avoiding cylinder is fixedly connected to the rear side of the moving frame 31, the cylinder rod of the avoiding cylinder is connected to the bottom of the lifting cylinder 4, the sliding rail 13 is arranged on the moving frame 31, the top of the sliding block 14 is connected to the bottom of the lifting cylinder 4, and the avoiding cylinder drives the lifting cylinder 4 to move forward and backward. When the workpiece is withdrawn, the lifting cylinder 4 is contracted, and the feeding rod is lowered to the bottom of the cavity. At this time, since the size of the cavity is limited, the fine positioning pin 12 is withdrawn from the positioning hole, and part of the nut of the pull rivet nut is located in the pull rivet nut limiting hole 7, the avoiding cylinder is extended, the feeding rod 5 can be moved forward, the nut of the pull rivet nut reaches the avoiding groove, then the feeding cylinder 3 is extended, the nut is moved out of the avoiding groove, and the feeding rod 5 can be smoothly withdrawn.

[0021] The above only describes the preferred embodiments of the present application, and it should be pointed out that, for ordinary skilled persons in the technical field, some improvements and modifications can be made without departing from the technical principles of the present application, and these improvements and modifications should also be regarded as the protection range of the present application.
