[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Specific examples are given below.
[0024] like Figures 1 to 3 As shown, a combined tapping machine fixture described in an embodiment of the utility model comprises a tapping machine body 1; the tapping machine body 1 is connected to a round plate 11; the side wall of the round plate 11 is connected to a hexagonal plate 12; the side wall of the tapping machine body 1 is connected to a top nozzle 13; the side walls of the round plate 11 and the hexagonal plate 12 are both provided with a plurality of first slots 14; the first slot 14 is a hexagonal slot at one end and a round slot at the other end; the end of the top nozzle 13 is provided with a second slot 15; the second slot 15 is a hexagonal slot at one end and a round slot at the other end; when working, The rivet nut is placed in the first slot 14 and then fixed by the second slot 15. At this time, the first slot 14 and the second slot 15 have hexagonal and round ends respectively, which can fit the shape of the rivet nut. In this step, the first slot 14 and the second slot 15 are configured with hexagonal and round ends respectively to fit the shape of the rivet nut, so as to reduce the gap between the rivet nut and the round plate 11 and the hexagonal plate 12, thereby reducing the slippage of the rivet nut during tapping, and at the same time reducing the deformation caused by the tap squeezing the rivet nut during tapping, which affects the quality of the finished product.
[0025] like Figure 1As shown, a connecting rod 2 is fixedly connected to the side wall of the tapping machine body 1; a stripping knife 21 is fixedly connected to the middle part of the connecting rod 2; the hexagonal plate 12 is provided with a stripping groove 22; during operation, when the tapping is completed, the rotation of the round plate 11 and the hexagonal plate 12 will drive the rivet nut to rotate, and when the rivet nut contacts the stripping knife 21, the stripping knife 21 can push the rivet nut out of the first slot 14. In this step, by setting the connecting rod 2 to connect the stripping knife 21 and cooperate with the stripping groove 22, it is convenient to remove the rivet nut from the first slot 14 after the tapping is completed, thereby improving the convenience of stripping.
[0026] like Figure 2 As shown, the stripping groove 22 is arranged in the middle of the hexagonal plate 12; the stripping groove 22 is rotatably matched with the stripping knife 21; when working, the stripping knife 21 is obliquely inserted in the stripping groove 22, and when the hexagonal plate 12 rotates, the rivet nut will contact with the stripping knife 21 and the rivet nut will be pushed out. In this step, by arranging the stripping groove 22 in the middle of the hexagonal plate 12, the stripping knife 21 can contact with the middle of the rivet nut when pushing the rivet nut out, thereby reducing the situation where the position is skewed and extrusion deformation occurs when the rivet nut is pushed out.
[0027] like Figure 3 As shown, the end of the top nozzle 13 contacts the round plate 11 and the hexagonal plate 12; the end of the top nozzle 13 is set as an arc surface; when working, when the top nozzle 13 cooperates with the round plate 11 and the hexagonal plate 12 to clamp and fix the rivet nut, the end of the top nozzle 13 is set as an arc surface to fit the arc surface of the round plate 11 and the hexagonal plate 12. In this step, by setting the end of the top nozzle 13 as an arc surface structure to fit the round plate 11 and the hexagonal plate 12, the gap between the top nozzle 13 and the round plate 11 and the hexagonal plate 12 can be reduced when the rivet nut is clamped and fixed, and the top nozzle can fit more closely with the rivet nut to improve the stability of clamping and fixing the rivet nut.
[0028] like Figure 1 and Figure 4 As shown, the side wall of the tapping machine body 1 is fixedly connected with a collection box 3; a pull-out box 31 is placed in the collection box 3; the pull-out box 31 and the collection box 3 are in sliding cooperation; during operation, when the stripping knife 21 pushes out the rivet nut, it will fall. At this time, the collection box 3 and the pull-out box 31 will collect the fallen rivet nuts. When the collection is completed, the pull-out box 31 is pulled out of the collection box 3 to take out the rivet nuts therein and then reset the pull-out box 31. In this step, the rivet nuts can be collected by setting the collection box 3 and the pull-out box 31. The pull-out box 31 can be extracted and put back to facilitate the removal of the collected rivet nuts, so as to improve the convenience of collection.
[0029] like Figure 4As shown, the side wall of the collection box 3 is fixedly connected with a baffle 4; the top of the baffle 4 is fixedly connected with a rubber pad 41; the baffle 4 and the rubber pad 41 are arranged in an arc shape; during operation, when the stripping knife 21 pushes out the rivet nuts, part of the rivet nuts fall on the top of the rubber pad 41. At this time, the rubber pad 41 is connected to the collection box 3 to enable the rivet nuts to slide into the pull-out box 31. In this step, by setting the baffle 4 and the rubber pad 41, the situation in which the rivet nuts fall from the gap between the collection box 3 and the round plate 11 and the hexagonal plate 12 when the stripping knife 21 pushes them out can be reduced, so as to improve the collection stability. The rubber pad 41 can reduce the impact force generated by the rivet nuts falling on the surface of the baffle 4 and play a protective role.
[0030] like Figure 4 As shown, a sponge pad 5 is placed in the pull-out box 31; during operation, when the rivet nut falls into the pull-out box 31, the sponge pad 5 can cushion it. In this step, by providing the sponge pad 5, the damage caused by the collision between the rivet nut and the bottom of the pull-out box 31 when the rivet nut falls into the pull-out box 31 can be reduced.
[0031] Working principle: Place the rivet nut at the first slot 14 and then fix it through the second slot 15. At this time, the first slot 14 and the second slot 15 have a hexagonal mouth and a round mouth at both ends, which can fit the shape of the rivet nut. When the tapping is completed, the rotation of the round plate 11 and the hexagonal plate 12 will drive the rivet nut to rotate. When the rivet nut contacts the stripping knife 21, the stripping knife 21 can push the rivet nut out of the first slot 14. The stripping knife 21 is obliquely inserted in the stripping groove 22. When the hexagonal plate 12 rotates, the rivet nut will contact the stripping knife 21 and push the rivet nut out. The top nozzle 13 cooperates with the round plate 11 and the hexagonal plate 12 to align the rivet nut. When the female clamp is fixed, the end of the nozzle 13 is arranged in an arc surface on the circular mouth plate 11 and fits the arc surface of the hexagonal mouth plate 12. When the stripping knife 21 pushes the rivet nut out, it will fall. At this time, the collection box 3 and the pull-out box 31 will collect the fallen rivet nuts. When the collection is completed, the pull-out box 31 is pulled out of the collection box 3 to take out the rivet nuts therein and then reset the pull-out box 31. When the stripping knife 21 pushes the rivet nut out, part of the rivet nut falls on the top of the rubber pad 41. At this time, the rubber pad 41 is connected to the collection box 3 to allow the rivet nut to slide into the pull-out box 31. When the rivet nut falls into the pull-out box 31, the sponge pad 5 can cushion it.
