[0025] In an embodiment of the present application, through a chuck 12 assembly and a pushing assembly, a material pipe clamp 30 is provided above the chuck 12 assembly, and the material pipe clamp 30 is used to clamp the conveying material pipe; the chuck 12 assembly is connected to one end of the pushing assembly, and the chuck 12 assembly includes a connecting block 11, a chuck 12 and a flip head 13, one end of the connecting block 11 is connected to the pushing assembly, and the other end of the connecting block 11 is connected to one end of the flip head 13; the chuck 12 is arranged at the other end of the flip head 13, and the chuck 12 is composed of two rotating blocks 121, and the outer side walls of the two rotating blocks 121 are respectively connected to the side walls of the flip head 13 through a first elastic member 122, and the relative inner walls of the two rotating blocks 121 are provided with arc grooves, and the two arc grooves are spliced ​​to form a bolt discharge hole 123. The material pipe clamp 30 is used to clamp the material pipe, and the bolt is sent from the material pipe to the clamp head 12 assembly below for clamping. The clamp head 12 assembly is pushed by the push assembly to move above the bolt welding position, and the spot welder is pressed down to make the two rotating blocks 121 of the clamp head 12 rotate outward at the same time, so that the bolt discharge hole 123 is opened, and the bolt is pressed down to the welding position and directly welded by the spot welder. The present application can realize automatic bolt conveying and cooperate with the electric welder to synchronously complete the bolt welding assembly, without manual operation, saving manpower, and improving the bolt assembly efficiency.

[0026] Next, the bolt feeding gun in this exemplary embodiment will be further described.

[0027] In the embodiment of the present application, a material pipe clamp 30 is provided above the chuck 12 assembly, and the material pipe clamp 30 is used to clamp the conveying material pipe. The conveying material pipe receives the bolts from the bolt distributor and conveys them to the chuck 12 assembly below, and the chuck 12 assembly cooperates with the spot welding machine to discharge the material.

[0028] The chuck 12 assembly is connected to one end of the push assembly. The push assembly is used to push the chuck 12 assembly to move forward and backward, send the bolts into the welding position for welding, and then return to the original position to cyclically receive the bolts sent by the conveying pipe, so as to improve the efficiency of bolt conveying and assembly. The chuck 12 assembly includes a connecting block 11, a chuck 12 and a flip head 13. One end of the connecting block 11 is connected to the push assembly, and the other end of the connecting block 11 is connected to one end of the flip head 13; the chuck 12 is arranged at the other end of the flip head 13, and the chuck 12 is composed of two rotating blocks 121. The outer side walls of the two rotating blocks 121 are respectively connected to the side walls of the flip head 13 through the first elastic member 122. The relative inner walls of the two rotating blocks 121 are provided with arc grooves, and the two arc grooves are spliced ​​to form a bolt discharge hole 123.

[0029] The connecting block 11 is pushed to move by the pushing assembly, and the connecting block 11 drives the flip head 13 and the chuck 12 to move synchronously. The chuck 12 is composed of two rotating blocks 121 spliced ​​together, thereby forming a bolt discharge hole 123 to carry and discharge the bolts. Specifically, the chuck 12 is pushed forward to above the bolt welding position. When the spot welding machine moves downward and presses the bolt downward from the bolt discharge hole 123, the two rotating blocks 121 rotate outward synchronously to open the bolt discharge hole 123, so that the spot welding machine directly pushes the bolt to the welding position below, and can directly perform welding assembly; thereafter, under the action of the first elastic member 122 between the rotating block 121 and the flip head 13, the two rotating blocks 121 can be reset to the spliced ​​state, and the bolts are transported and discharged reciprocatingly.

[0030] Further, refer to Figure 3 The first elastic member 122 includes a pin and a first spring. The pin is inserted through the flip head 13 and the clamp 12, and the first spring is sleeved on the pin. A rotation groove is provided at the end of the flip block 131, and a connecting ear is provided at the end of the rotating block 121 to extend into the rotation groove, which is connected through the pin, and then sleeved with the first spring so that it can be reset after opening.

[0031] As an example, the flip head 13 is composed of two flip blocks 131, which are connected by a second elastic member 132, and the two flip blocks 131 are rotatably connected to the connection block 11 by a rotating shaft 133. Through the above structure, when the electric welder pushes the bolt downward, the flip block 131 can be flipped downward synchronously, that is, it cooperates with the rotating block 121 to achieve the flipping of the flip block 131 when the rotating block 121 is opened, and at the same time, under the recovery of the pushing component, it is quickly separated from the spot welder to avoid mutual influence during the bolt welding process, so that the chuck 12 component returns to the bottom of the conveying pipe to receive the next bolt. Among them, the second elastic member 132 is a second spring.

[0032] As an example, the bolt discharge hole 123 is a tapered hole. Since bolts generally have a large head and a small body, the bolt discharge hole 123 is designed as a tapered hole, which can better match the bolt structure.

[0033] As an example, the pushing assembly includes a pushing cylinder 21 and a pushing rod 22, one end of the pushing rod 22 is connected to the pushing cylinder 21, and the other end of the pushing rod 22 is connected to the connecting block 11. The pushing cylinder 21 is driven to drive the pushing rod 22 to move forward and backward, thereby driving the connecting block 11 and the flip head 13 and the chuck 12 to move synchronously.

[0034] As an example, a fixed seat 23 is sleeved on one end of the push rod 22 away from the push cylinder 21, and the material pipe clamp 30 is connected to the fixed seat 23 through a connecting plate 31. During the movement of the push rod 22, the fixed seat 23 is fixed, and the material pipe clamp 30 is fixed to the fixed seat 23 to fix and support the material pipe clamp 30 so that it is fixed and can stably receive the bolts from the distributor and deliver the bolts to the clamp 12 below without affecting the movement and discharge of the clamp 12 assembly.

[0035] As an example, a copper slider 231 is provided in the fixing seat 23, and the copper slider 231 is sleeved on the outside of the push rod 22. The copper slider 231 can reduce friction, accelerate heat dissipation, and increase service life. A mounting groove can be provided on the side wall of the fixing seat 23 for mounting the copper slider 231, and the mounting groove is covered by a cover plate. When the copper slider 231 is worn out after long-term use, it is easy to disassemble and replace.

[0036] As an example, a sheath 24 is provided at one end of the fixing seat 23 away from the chuck 12 assembly, and the push rod 22 is slidably arranged in the sheath 24. By providing the sheath 24 outside the push rod 22, the push rod 22 can be protected and its service life can be extended.

[0037] As an example, a gun support 25 is fixed on the sheath 24, and the gun support 25 is used to be connected to the frame. The delivery gun can be fixed on the equipment frame through the gun support 25.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the utility model embodiments.
