Background technique

Pull riveting tools are widely used in the riveting of electromechanical and light industrial products such as automobiles, aviation, furniture and decoration, and are used in the fastening and riveting of various metal plates, pipes and other manufacturing industries. The common rivet tool is a rivet gun, which can be divided into manual rivet gun, pneumatic rivet gun and electric rivet gun in terms of driving mode.

In order to ensure that the rivet is riveted stably to fix the riveted parts, most of the rivets are provided with an annular groove. The rod of the rivet will be stuck, and the rod will be pulled for riveting. Because of this, when the user is using the rivet gun, if the rivet is inserted into the rivet mouth by mistake but does not require riveting operation or the rivet is riveted after the rivet is riveted badly (the rivet head is not broken), it is necessary to remove the rivet. Take it out from the rivet gun, but at this time, the rivet will be clamped by the claw in the rivet mouth to the annular groove on the nail body, so that the rivet cannot be pulled out from the rivet mouth by hand.

In view of the above situation, a structure for easily taking out the rivet from the riveting tool can solve this problem, and there is no such rivet-removing design in the existing riveting tool.

Different from the prior art, the side walls of the riveting nozzle 1 and the riveting sleeve 2 are respectively provided with toggle holes 4 that penetrate through the inside and outside. The hole 4 corresponds to the position of the toggle hole 4 on the riveting sleeve 2, and the claw assembly 3 is provided with a tool insertion portion 5 corresponding to the position of the toggle hole 4, so as to toggle the claw through the nail removal tool 10. Assembly 3 to release rivet 11. When the riveting assembly is in the non-riveting state, the tool inserting portion 5 can be exposed through the toggle hole 4 , and the tool inserting portion 5 is toggled backward by the nail taking tool 10 , so that the claw assembly 3 is opposite to the riveting sleeve 2 . After moving backward, the jaw assembly 3 releases the rivet 11 inserted into the rivet mouth 1 , so that the rivet 11 can be easily taken out.

Specifically in this embodiment, at least one toggle hole 4 on the above-mentioned riveting mouth 1 and riveting sleeve 2 is provided, for example, three toggle holes 4 can be evenly arranged along the circumferential direction, which can facilitate the retrieval from multiple directions. The nail operation makes the nail removal operation more flexible and convenient. The toggle hole 4 can be designed as a circular hole, a waist-shaped hole or a special-shaped hole, and the size of the toggle hole 4 can be slightly larger than the tool insertion portion 5, so as to leave enough space for rear dial. Figures 1 and 2 show an embodiment in which the toggle hole 4 adopts a waist-shaped hole, and Figure 4 shows another embodiment in which the toggle hole 4 adopts a circular hole. The above-mentioned tool insertion portion 5 can adopt various structural forms, as long as the nail removal tool 10 can be used to move it backwards. For example, the tool insertion portion 5 can be designed as a hole or a groove. When the tool insertion portion 5 adopts a hole, A through hole or a blind hole can be used, and the shape of the hole can be circular, etc. When the tool insertion part 5 uses a groove, a partial groove or an annular groove can be used. Adopting the above-mentioned design of the toggle hole 4 and the tool insertion portion 5, the structure design is simple, the processing is convenient, and the manufacturing cost of the rivet gun is not increased.

In this embodiment of a riveting assembly with a nail-removing function, the function of the tool insertion part 5 on the claw assembly 3 is to use the nail-removing tool 10 to move the claw assembly 3 to drive the claw head at the front end to move backwards. Loosen the rivet lever. The claw assembly 3 can adopt the existing design, such as the common combination design of the spring and the three-claw claw. At this time, the tool insertion part 5 can be arranged on the tail rod of the three-claw claw. Specifically in this embodiment, the above-mentioned claw assembly 3 includes a rubber tube 3-1 and a claw head 3-2. The claw head 3-2 is arranged at one end of the rubber tube 3-1, and the tool insertion portion 5 is arranged at the rubber tube 3. -1 on the side wall. The claw head 3-2 can be set to three, the claw head 3-2 is made of metal material, and is provided with a tooth shape matched with the annular groove on the rivet rod, and the claw head 3-2 can be integrated by a rubber coating process It is formed at the front end of the rubber tube 3-1, and the rubber tube 3-1 is used to maintain the elasticity of the claw head 3-2. The rubber tube 3-1 and the claw head 3-2 are combined to form the rivet jaw, the structure is simple and compact, the assembly is simple and convenient, and the tool insertion part 5 is arranged on the rubber tube 3-1, which is more convenient to manufacture. The rubber tube 3-1 can make the front claw head 3-2 release the rivet rod, which is flexible and convenient to operate. Specifically, as shown in Figures 2 and 3, an inner tapered surface 2-1 that matches the outer tapered surface 3-2-1 on the claw head 3-2 is provided on the inner side of the front end of the riveting sleeve 2. The riveting sleeve 2 There is also an inner ring groove 2-2 connected to the rear side of the inner cone surface 2-1. The inner diameter of the inner ring groove 2-2 is larger than the outer diameter of the claw head 3-2, so that the claw head 3-2 can be more convenient. The ground expands outward, and it is more convenient to take out the rivet with the back-moving action of the claw assembly.

The present embodiment also relates to a rivet gun, which includes a body and the above-mentioned pull riveting assembly with a nail-removing function, and the pull riveting assembly is installed on the body. The body can be driven manually, pneumatically or electrically, and the rivet 11 can be riveted by driving the riveting sleeve 2 to move axially relative to the rivet nozzle 1 . Specifically, the rear end of the riveting nozzle 1 is connected with the coupling sleeve 7 through the locking nut 6 , the rear end of the coupling sleeve 7 is fixed on the casing of the body through the fixing sleeve 8 , and the rear end of the riveting sleeve 2 is connected to the body through the coupling shaft 9 . connected to the internal movement mechanism. When applied in the electric rivet gun, the movement mechanism in the body can adopt the ball screw nut transmission mechanism, and the motor and the deceleration mechanism are used to drive the screw nut to rotate, thereby driving the screw rod to move back and forth, and the screw rod is connected with the connecting shaft 9, thus Realize the riveting of rivets.

In order to further understand the content of the present invention, the operation method of a pull riveting assembly with a nail-removing function and a rivet gun of the present invention will now be further described with reference to FIG. 5 and FIG. 6 .

During the normal riveting operation, insert the nail rod of the rivet 11 from the rivet nozzle 1 and the hole at the front end of the rivet sleeve 2, and push the nail rod away from the claw head 3-2 of the claw assembly 3 to be inserted. At this time, the rubber tube 3- Under the elastic force of 1, the claw head 3-2 abuts on the front end of the rivet sleeve 2, and the rivet 11 cannot be pulled out due to the cooperation of the taper surface to bite the nail rod inwardly. When the rivet gun is in action, the motion mechanism drives the rivet sleeve 2 to move backward, and drives the claw head 3-2 to move backward together through the cooperation of the tapered surface. The rivets 11 move backward together to realize the riveting of the rivets 11 .

As shown in FIG. 6 , when the rivet 11 is mistakenly inserted without riveting or poor riveting and the rivet 11 is left on the tool, the toggle hole 4 and the tool insertion part 5 can be opposite to each other by rotating the rivet mouth 1 and the riveting sleeve 2 (Three holes in one), use the nail removal tool 10 to insert the tool insertion part 5 and dial it backward.
