[0042] The following will be combined with 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.

[0043] like Figure 1~Figure 5 As shown, this embodiment proposes a double-head chamfering device for the production of double-headed bolts, including a double-headed chamfering machine body 1, and also includes a material receiving box 2, a buffer unloading mechanism, a buffer plate 3, a storage and sorting mechanism and a conveyor belt 4. The buffer unloading mechanism is installed in the material receiving box 2, wherein the buffer unloading mechanism includes a buffer plate 3, and the buffer plate 3 is tilted and fixedly connected in the material receiving box 2. The storage and sorting mechanism is installed on the bottom inner wall of the material receiving box 2, wherein the storage and sorting mechanism includes a conveyor belt 4, and the conveyor belt 4 is located on the bottom inner wall of the material receiving box 2. First, the double-headed screw to be chamfered is fixed on the double-headed chamfering machine body. 1, and then the double-head chamfering machine body 1 chamfers both ends of the double-headed screw at the same time, which is more efficient and has a good chamfering effect. Then the clamp is sent away, and the double-headed screw rolls onto the buffer plate 3. The buffer unloading mechanism intercepts the rolling double-headed screw and squeezes it onto the storage and sorting mechanism. The storage and sorting mechanism arranges the double-headed bolts neatly and stacks them in the receiving box 2 to prevent the unreasonable use of space due to the uneven arrangement of the double-headed bolts, which increases the difficulty of workers in collecting. The buffer unloading mechanism can well protect the double-headed screw from damage, and prevent the double-headed screw from rolling out of the equipment due to excessive inertia, resulting in difficulty in collection.

[0044] Among them, the buffer unloading mechanism includes a limit plate 5, a discharge hole and a buffer assembly. Two limit plates 5 are provided. The two limit plates 5 are fixedly connected to the two sides of the buffer plate 3. The discharge hole is opened at the top of the receiving box 2. The buffer plate 3 is fixedly connected below the discharge hole. The buffer assembly is installed on the buffer plate 3. The double-headed screw falls on the buffer assembly through the discharge hole. The buffer plate 3 is wrapped with a rubber layer to prevent collision. The limit plate 5 prevents the double-headed screw from rolling out.

[0045] Secondly, the storage and sorting mechanism includes a transmission shaft 6, a limit plate 27, a motor 8 and a discharge assembly. There are two transmission shafts 6, which are rotatably connected to the bottom end of the material receiving box 2, and the conveyor belt 4 is installed between the two transmission shafts 6. There are two limit plates 27, which are fixedly connected to the two sides of the conveyor belt 4 respectively. The height of the two limit plates 27 is slightly higher than the conveyor belt 4.

The discharge assembly is installed in the material receiving box 2, and the discharge assembly contacts the conveyor belt 4. The double-headed screw first falls on the conveyor belt 4, and the motor 18 drives the transmission shaft 6 to rotate, thereby driving the conveyor belt 4 to rotate and transmitting the double-headed screw to a position next to the edge of the material receiving box 2, and then the discharge assembly pushes the double-headed screw off the conveyor belt 4, and the double-headed screw rolls to the other side on the slope in the material receiving box 2 and is arranged in sequence.

[0046] Again, the buffer assembly includes a through hole, a U-shaped plate 9, a feed roller 10, a spring telescopic rod 11 and a motor 2 12. There are three through holes, and the three through holes are opened on the buffer plate 3. There are six U-shaped plates 9, and two U-shaped plates 9 are installed in each through hole.

There are six motors 2 12, and the six motors 2 12 They are all fixedly connected to the limit plate 1 5, and the output ends of the six motors 2 12 are fixedly connected to the six unloading rollers 10 respectively, wherein the motor 2 12 and the limit plate 1 5 are slidably connected, and two adjacent motors 2 12 rotate in the direction between the two motors 2 12, so that when the double-headed screw rolls onto the unloading roller 10, the friction force between the unloading roller 10 and the double-headed screw will squeeze the double-headed screw downward, thereby pushing the spring telescopic rod 11, so that the double-headed screw falls into the receiving box 2, thereby achieving the purpose of buffering and tidy arrangement.

[0047] Among them, the discharge assembly includes a mounting plate 13, a push plate 14 and a cylinder 15. The mounting plate 13 is fixedly connected to the inner wall of the bottom end of the material receiving box 2, the push plate 14 is located above the conveyor belt 4, and the cylinder 15 is fixedly connected to the mounting plate 13. The output end of the cylinder 15 is fixedly connected to the push plate 14. When working, the cylinder 15 starts to push the push plate 14 to push the double-headed screw down the conveyor belt 4 into the material receiving box 2.

[0048] Finally, the surface of the conveyor belt 4 is provided with a plurality of grooves for increasing the friction with the double-headed screw. Meanwhile, the grooves help to adjust the direction of the double-headed screw so that the double-headed screw is more neat in the receiving box 2.

[0049] In this embodiment, the double-headed screw is first placed in the double-headed chamfering machine body 1 for chamfering, and then the double-headed screw falls onto the buffer plate 3, and is squeezed into the material receiving box 2 through the buffer assembly, and falls onto the conveyor belt 4. The conveyor belt 4 is driven by the motor 8 to transport the double-headed screw to the discharge assembly position, and is pushed down the conveyor belt 4 by the push plate 14 and arranged in the material receiving box 2, so that the double-headed screw is arranged more neatly and is more convenient to take and record the quantity.
