Clamp body

Abstract

The invention discloses a clamp body. An installation sleeve is arranged outside each elastic sheet in the clamp body, wherein the front end of the elastic sheet is provided with a clamping end which is an open state while being exposed out of the front end of the installation sleeve to outwards open, and is in an closed state while being folded to the installation sleeve to close inwards; the hole wall or the front end port of the installation sleeve is provided with a close-up edge which is blocked and matched with an elastic claw along the front and rear direction when the clamping end is in the open state, and is blocked outside the elastic claw when the clamping end is in the closed state. During a using process, the close-up edge is matched with the clamping end to realize the opening-closing motion of the elastic claw, thereby realizing clamping a cylindrical solid tool to be grinded and improving the clamping speed of the cylindrical solid tool. Moreover, self-centering is realized through the matching of wedge surfaces, and the precision of clamping the cylindrical solid tool and grinding and machining the tool is improved.

Description

technical field [0001] The invention relates to the technical field of tool grinding fixtures. Background technique [0002] At present, the grinding of the blade of the tool is usually done manually. When the grinding wheel is grinding the tool head, the handle of the tool is held tightly by hand to achieve the grinding of the tool. This method not only increases the labor of the staff Intensity, and the amount of grinding in the grinding process needs to be determined by the experience of the staff, thereby reducing the accuracy of the grinding process and reducing the processing efficiency. [0003] The Chinese invention patent with the notification number CN201645276U discloses a sheet tool grinding jig for grinding machines. The jig includes a jig body and a tapered screw. ) on the tail handle rod and the front end are provided with an expansion body with a circular cross-section for clamping the tool to be ground. The tail handle rod is a Morse taper handle, and the e...

[0003] The Chinese invention patent with the notification number CN201645276U discloses a sheet tool grinding jig for grinding machines. The jig includes a jig body and a tapered screw. ) on the tail handle rod and the front end are provided with an expansion body with a circular cross-section for clamping the tool to be ground. The tail handle rod is a Morse taper handle, and the expansion body is a four-petal fixed diameter The retractable claws are provided with internal threads on the inner surface of the expansion body for screwing with the conical screw. , and then by tightening the conical screw on the expansion body, so that the four-lobed claws are all spread out to tighten the sheet tool to be ground, and position the sheet tool to be ground, so that the scope of application of the fixture Effective, that is, it is mainly suitable for the grinding of ring tools, but for ordinary solid cylindrical tools, the fixture can be clamped and positioned, so that cylindrical solid tools still need to be ground by hand, so that the columnar solid The cutting tool still has the problems of low processing efficiency and low processing accuracy
