Problems solved by technology

[0002] The thickness of the end of the flat wrench is required to be accurate and thin. Due to the high hardness value, it is generally (50-54) HRC. However, because the shape and size of the flat wrench have various specifications, different specifications can be clamped when using surface grinding. Fixtures need to be adjusted when making parts, which affects processing efficiency

Embodiment Construction

[0017] The present invention is described in detail below in conjunction with accompanying drawing:

[0018] The utility model relates to a clamping tool suitable for grinding the end of a flat wrench. The clamping is completed by a base, a shaft sleeve, a top shaft, a spring, a top sleeve and a vise.

[0019] The base is a U-shaped structure, one end is used for lapping the end of a flat-head wrench, and the other end is equipped with a bushing. Centering of the overlapping surfaces of the end surfaces, (the position of the center line of the top axis and the axis of the slotted wrench on the upper end surface of the left end of the base 1 is collinear) can realize the horizontal placement of the slotted wrench. The spring is installed on the top shaft, and the top sleeve is sleeved on the outer circle of the shaft sleeve. When the vise clamps the base and the top sleeve, the top sleeve compresses the spring to realize the clamping of the flat wrench. The top shaft can be ad...

Abstract

The invention provides a clamping tool and method for grinding the ends of straight spanners, and belongs to the technical field of machining processes. The defects in an existing machining method areovercome, the straight spanners of multiple specifications can be machined through the tool, and the machining efficiency is improved. A base, a shaft sleeve, a center shaft, a spring and an ejectorbush cooperate with a vice to complete clamping. The center shaft can be adjusted according to the lengths of the straight spanners. When parts are replaced, rapid clamping can be completed through the telescopic action of the spring. The tool is used for achieving rapid clamping, the thicknesses of the ends of the straight spanners are machined, the clamping difficulty is lowered, and the clamping tool and method are more suitable for volume production.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing technology, and relates to a fast clamping tool and method for grinding the end of a flat wrench. Background technique [0002] The thickness of the end of the flat wrench is required to be accurate and thin. Due to the high hardness value, it is generally (50-54) HRC. However, because the shape and size of the flat wrench have various specifications, different specifications can be clamped when using surface grinding. Fixtures need to be adjusted when making parts, which affects processing efficiency. Contents of the invention [0003] The object of the present invention is to provide a fast clamping tool and method for grinding the end of a slotted wrench, which overcomes the shortcomings of the existing processing methods, and can process slotted wrenches of various specifications by using a tooling to improve processing efficiency. [0004] The technical solution of the presen...
