Description

Technical Field

[0001] The utility model relates to the technical field of bolt production and processing, in particular to end deburring equipment for bolt production. Background Art

[0002] A bolt is a mechanical part, a cylindrical threaded fastener that is matched with a nut. It is a type of fastener consisting of a head and a screw (a cylinder with external threads). It needs to be matched with a nut to fasten and connect two parts with through holes.

[0003] The bolt production steps include raw material selection, cold forging, rough machining, heat treatment, fine machining and surface treatment. After fine machining, the bolt has become a finished product. However, some burrs will still remain at the end of the bolt. Therefore, the end of the bolt needs to be deburred in the final step to avoid too many burrs that cannot fit the nut.

[0004] The existing methods for deburring the ends of hexagonal bolt rods are mostly done by manually holding an electric drill and using a burr chamferer to chamfer and deburr the bolt rod. The deburring efficiency is low, and during the deburring process of the bolt rod ends, the bolts are prone to position displacement, affecting the deburring effect. In view of this, we propose an end deburring device for bolt production. Utility Model Content

[0007] The limiting mechanism includes a first electric push rod, which is fixed to the inner wall of the base. Two groups of the first electric push rods are provided. The movable end of the first electric push rod is connected to a limiting slot frame. A model frame is engaged inside the limiting slot frame, and a plurality of fixing slots are opened on the surface of the model frame.

[0008] Preferably, the model frame is engaged with the inner part of the limiting groove frame and is in the shape of a rectangular parallelepiped, and the exposed protruding part of the model frame is in the shape of a trapezoid.

[0009] Preferably, a group of symmetrical fixing grooves can form a hexagonal shape.

[0010] Preferably, the grinding mechanism includes a second electric push rod, which is arranged on the top of the base. There are two groups of second electric push rods. The movable end of the second electric push rod is connected to a load-bearing plate. A motor is provided in the middle of the load-bearing plate. A plurality of limiting shafts are engaged inside the load-bearing plate.

[0011] Preferably, the limiting shaft rod is in an I-shape, and the vertical rod portion of the limiting shaft rod is matched and movably engaged in the interior of the load-bearing plate.

[0012] Preferably, the active grinding disc is meshed with the driven grinding disc, and the active grinding disc and the driven grinding disc have the same shape and structure.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model effectively limits the hexagonal bolts through the model frame, thereby improving the placement stability of the hexagonal bolts.
