[0033] As shown in FIG. 1, Figures 1 to 3 The present embodiment proposes a screw top end automatic slotting equipment, which comprises a base 1, further comprising:

[0034] A support 2 is fixedly arranged on the base 1, and a rotating shaft 4 is rotatably connected to the support 2, a rotating seat 5 is fixedly arranged on the rotating shaft 4, and a placing groove 501 for placing a screw piece 7 is arranged on the rotating seat 5 in a circumferentially uniform manner;

[0035] A transmission part 6 is fixedly arranged on the support 2, and a cutting part 8 for cutting a slot at the top of the screw piece 7 is connected to the end of the transmission part 6 away from the support 2;

[0036] Among them, the support 2 is fixedly arranged with a feeding shell 9 for placing the screw piece 7, and the feeding shell 9 is arranged on the support 2 in an inclined manner;

[0037] The screw 7 to be slotted is placed inside the feeding housing 9. The screw 7 enters the placement slot 501 of the rotating seat 5 along the inner wall of the feeding housing 9. By controlling the operation of the transmission unit 6, the transmission unit 6 drives the rotating shaft 4 on the bracket 2 to rotate. The rotating shaft 4 drives the rotating seat 5 to rotate and moves the screw 7 placed in the placement slot 501 to the slotting position. When the transmission unit 6 is working, it also drives the cutting part 8 to move, so that the cutting part 8 performs slotting work on the top of the screw 7 that has moved to the slotting position. There is no need for the operator to accurately place the screw 7 in the slotting position (the slotting position is directly in front of the cutting part 8), which improves the feeding and unloading speed when slotting screws. Moreover, there is no need to place the screw near the cutting part 8, which improves the working efficiency and safety of slotting the top of the screw.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, the upper and lower ends and the side of the feeding shell 9 are provided with openings. The upper opening of the feeding shell 9 is connected to the feeding hopper 901, and the support 2 is provided with a communication port 10 for connecting the lower opening of the feeding shell 9 and the placement groove 501.

[0039] When the screw 7 is placed, it enters through the upper opening of the feeding housing 9. The feeding hopper 901 has a large opening, and the feeding hopper 901 is designed to facilitate the quick placement of the screw 7 into the feeding housing 9. The screw 7 slides down the inner wall of the feeding housing 9 and enters the placement slot 501 through the connecting port 10. The opening on the side of the feeding housing 9 facilitates the separation of the top of the screw 7 from the body of the screw 7.

[0040] like Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, the support 2 further includes a support plate 201 fixedly connected to the base 1 and an arc-shaped shell 202 fixedly connected to the support plate 201. The arc-shaped shell 202 is sleeved on the outside of the rotating seat 5 and is fixedly connected to the feeding shell 9.

[0041] The bracket 2 is fixed to the base 1 by the support plate 201. The arc-shaped shell 202 is designed to limit the screw 7 placed in the placement slot 501, ensuring the stability of the screw when the top of the screw is slotted. When the arc-shaped shell 202 no longer surrounds the rotating seat 5, the slotted screw 7 moves to a position where it is not surrounded by the arc-shaped shell 202 and automatically falls off as the rotating seat 5 rotates. There is no need for the staff to move their hands to the cutting position to unload the material, ensuring a safe working environment.

[0042] like Figure 1 , Figure 2 and Figure 3As shown, in a preferred embodiment, based on the above method, a U-shaped limiting plate 11 is further fixed at the bottom of the feeding shell 9, and a receiving area for accommodating the end of the screw 7 is formed between the inner wall of the U-shaped limiting plate 11 and the side wall of the feeding shell 9.

[0043] The U-shaped limiting plate 11, together with the side wall of the feeding shell 9, can limit the top of the screw 7, so that the screw 7 will not deviate and will be placed horizontally in the feeding shell 9. The tops of multiple screws 7 abut against each other, preventing the screws 7 from tilting and entering the placement groove 501, which would affect the smooth rotation of the rotating seat 5.

[0044] like Figure 1 , Figure 2 and Figure 6 As shown, in a preferred embodiment, based on the above method, the transmission unit 6 further includes a gearbox 601 fixedly connected to the bracket 2. The gearbox 601 is rotatably connected to a main gear 602, a large gear 603 intermittently meshing with the main gear 602, and a small gear 604 intermittently meshing with the large gear 603. A drive motor 3 for driving the large gear 603 is fixedly mounted on the gearbox 601. The main gear 602 is connected to and coaxially arranged with the rotating shaft 4. A reciprocating lead screw 12 is connected to the small gear 604. A sleeve 121 is threadedly connected to the reciprocating lead screw 12. The sleeve 121 is connected to the cutting part 8.

[0045] Furthermore, the large gear 603 is configured as an incomplete gear. When the large gear 603 meshes with the main gear 602, it does not mesh with the small gear 604. When the large gear 603 meshes with the small gear 604, it does not mesh with the main gear 602.

[0046] When the transmission unit 6 is working, it controls the drive motor 3 to run. The output shaft of the drive motor 3 drives the large gear 603 to rotate. When the large gear 603 rotates, it alternately meshes with the small gear 604 and the main gear 602. When the large gear 603 and the main gear 602 rotate, the main gear 602 rotates by the same angle each time. The main gear 602 drives the rotating seat 5 to rotate through the rotating shaft 4, causing the screw 7 in the placement slot 501 to rotate to the slotted position. Then the large gear 603 meshes with the small gear 604, causing the small gear 604 to rotate multiple times. The small gear 604 drives the reciprocating lead screw 12 to rotate multiple times, and the sleeve 12... 1. The screw moves axially along the reciprocating lead screw 12 and drives the cutting part 8 to move towards the screw part 7 at the slotted position. After the cutting part 8 slots the top of the screw, it moves back. As the large gear 603 continues to rotate, the large gear 603 rotates again with the main gear 602, causing the rotating seat 5 to drive the slotted screw part 7 to continue to rotate. The slotted screw part 7 is automatically unloaded, so that one drive source can drive the feeding action of the cutting part 8 and the rotation action of the rotating seat 5. The feeding action and the rotation action are alternated, so that the slotting work at the top of the screw is carried out in an orderly manner, ensuring the screw slotting processing cost while improving the screw slotting efficiency.

[0047] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the cutting component 8 further includes a protective shell 801 fixedly connected to the sleeve 121, a cutting motor 802 fixedly installed on the outside of the protective shell 801, and a cutting wheel 803 connected to the output shaft of the cutting motor 802 and rotatably connected inside the protective shell 801. The protective shell 801 is connected to a water nozzle 804 through a support, and the water nozzle 804 is connected to a water supply device through a water pipe.

[0048] When the cutting part 8 is working, the cutting motor 802 is running. The output shaft of the cutting motor 802 drives the cutting wheel 803 inside the protective shell 801 to rotate. The cutting wheel 803 can cut and groove the top of the screw part 7. The water spray head 804 is set to spray water on the grooved cutting area to avoid dust generated during cutting and avoid air pollution.

[0049] like Figure 2 and Figure 7 As shown, in a preferred embodiment, based on the above method, the bracket 2 is further provided with a groove 13, a positioning rod 131 is slidably connected in the groove 13, an elastic element 132 is provided between the positioning rod 131 and the inner wall of the groove 13, an arc surface is provided at the end of the positioning rod 131 away from the elastic element 132, and a positioning hole 502 corresponding to the placement groove 501 is provided in a circular pattern on the rotating seat 5.

[0050] A positioning rod 131 is elastically set on the bracket 2 (i.e., the lower side of the support plate 201) to facilitate auxiliary positioning of the rotating seat 5 after rotation, preventing the rotating seat 5 from rotating arbitrarily and affecting the grooving accuracy of the cutting part 8 on the top of the screw, thereby ensuring the quality of screw production and processing; only when the large gear 603 meshes with the main gear 602, the main gear 602 drives the rotating seat 5 to rotate through the rotating shaft 4, the rotating seat 5 moves under force and squeezes the arc surface at the end of the positioning rod 131, the positioning rod 131 avoids the rotation of the rotating seat 5 until the next positioning hole 502 on the rotating seat 5 moves to the positioning rod 131, the positioning rod 131 is pushed into the positioning hole 502 again under the push of the elastic element 132 to assist in positioning the rotating seat 5. The elastic element 132 is set as a spring.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
