Description

TECHNICAL FIELD

[0001] The application relates to the technical field of star wheel machining, in particular to a fixing clamp for star wheel machining. BACKGROUND

[0002] The clamp refers to a device used for fixing machining objects in the mechanical manufacturing process, so that the machining objects occupy correct positions to receive construction or detection, and is also called a fixture. In a broad sense, any device used for quickly, conveniently and safely installing workpieces in a process is called a fixture. A star wheel needs to be fixed by using a fixing clamp during machining.

[0003] According to the search, the announcement No. CN219336858U discloses a clamp for star wheel machining. In this technology, a placing plate, a containing groove, a lifting driving assembly and a pressing plate are disclosed. The placing plate is provided with a plurality of containing grooves for placing star wheels at the top end. The containing grooves are matched with the shape and size of the outer side of the star wheel. A center hole is formed at the center position of the star wheel. The lifting driving assembly is installed at the bottom end of the placing plate corresponding to the containing groove. A through hole is formed at the middle position of the bottom of the containing groove for the vertically upward extension of the extension end of the lifting driving assembly. The through hole is arranged opposite to the center hole on the star wheel. The extension end of the lifting driving assembly is detachably installed with the pressing plate. The extension end of the lifting driving assembly is moved downward to drive the lower end surface of the pressing plate to tightly abut against the upper end surface of the star wheel in the containing groove, so that the star wheel is fixed in the containing groove. The structure is simple, the cost is low, the star wheel can be conveniently, quickly and accurately clamped and fixed, and the star wheel will not shake or rotate during subsequent machining.
