Electric rivet gun improved structure

The utility model relates to an improved structure of an electric rivet gun, which is provided with a sliding sleeve seat of a metal steel inside the body of the gun head body, and a halved rib corresponding to the sliding part of the sliding ring sliding groove, which is opposite to the convex and concave of the key and the groove. When the sliding member for the rotation of the rotating rod is displaced, the sliding member can be guided and slid safely according to the insertion of the sliding slot, thereby ensuring the stability of the entire group of the pulling and controlling transmission structure, so that the pulling operation can be safe and practical. the goal of.

The structure of the traditional rivet gun machine is more common, such as the structure shown in the new patent case of "Molding Tip Structure Improvement" of M418762, which includes the lancet body and the internal rotating shaft and the passing rod. Thread-locking for pulling and controlling the moving guide of the rivet rod, which mainly adopts a cross section of the guiding end of the moving guiding member as a polygon, and a cross-sectional shape of the through hole in the body is matched with the polygonal section of the moving member for During the rivet operation, the moving guide and the rotating rotating rod structure simultaneously perform two kinds of movements of rotation and linear sliding, and the movable guide and the tip body can increase the receiving portion with a polygonal surface to disperse because of the rotation. The wear of the extension avoids the wear and deformation of the moving guide or the body, and achieves the expected effect of smooth reciprocating motion of the moving guide; the focus of the structural design is that the inside of the gun head body is polygonal, so that the moving guide has the same polygon The surface is assembled as a plug-in assembly, and the rotating rod is rotated and relatively screwed to form a screw-in pulling action, and the moving direction is transmitted through the engaging orientation of the polygonal surface. Converted by a rotary drive into a linear slip, so the entire moving part is the same When the torsion force is rotated and the guiding frictional resistance of the outer edge is multilateral, in order to reduce the frictional resistance of the entire sliding, the contact surface is designed as a thinner surface, so that the polygonal surface is inserted to achieve the respective sides. It does not form too much resistance. However, in this case, the head of the gun head is usually formed by plastic steel or aluminum or zinc die-casting. Its texture is soft, and the metal moving parts are twisted and stressed and sliding. Under the direction of force, the corners of the polygons in the body are often severely worn. Therefore, when the rivet operation is often performed, the corners of the inner polygon are rounded by wear, causing the moving parts to rotate. In severe cases, there will be a bad situation in which the jam can not be controlled. The reason is that the design of the gun head body is not proper, and because of the large force of the rotation and slip wear, how to reduce the contact area and achieve Compared with the improvement of the coating guide, the rotation force and the sliding force are separately guided to effectively improve the design of the current rivet machine. Therefore, the transfer structure of the current rivet gun has a further weight. Design improvements necessary in order to achieve safety tips when Rivet structural assembly operations and require the use of continuous operation, also goes precisely this reason the creation of research and improvement.

In view of the practical design flaws in the use of the built-in structure of the traditional rivet gun head, the creator has developed a new improved structure of the electric rivet gun with the redesigned design, and the body of the gun head is set as an activity. Inner and outer cladding structure of the assembly, built-in metal steel hard sliding sleeve, the ring is provided with equally divided sliding grooves, and the outer annular surface of the sliding member is provided with ribs in the shape of convex keys with equal divisions. The guide for inserting into the chute for locking and slipping, effectively improving the lack of practicality derived from the easy wear and tear when the pull control drive device is used.

The main purpose of this creation is to make the independent activity of the gun head body, with a rigid steel sliding sleeve, outer plastic material overmolding, sliding sleeve The sliding piece with the same metal material can be used to ensure the safety and stability of the drive. It can be guided by the key and slot type to ensure the sliding part of the sliding piece is safely slipped when it is converted into a sliding movement. The control and guiding operation is used for the rivet operation to achieve the safety and practical effect and purpose of driving.

Another purpose of the creation is to lock the metal T-shaped end piece through the outer end of the sliding sleeve, and the disc-shaped ends are oppositely arranged with the screw hole seat for the adjustable auxiliary length of the telescopic length and the width of the handle. The lock group is integrated with the nail gun body of the general electric and pneumatic drilling tools, and the nail can be safely operated by one hand, and the structure assembly is simple, safe and practical.
