Honing fixture with rotatable drill point

Abstract

A honing fixture with a rotatable drill point comprises a workpiece rotating clamping assembly and a fixing fixture assembly. The workpiece rotating clamping assembly is mounted in the fixing fixture assembly and comprises a left clamping plate, a right clamping plate, a first bearing and a large gear. The left clamping plate and the right clamping plate are spliced and fixed. Semi-circular grooves are formed in the opposite faces of the left clamping plate and the right clamping plate. The two semi-circular grooves are matched to form a bearing mounting groove allowing an outer ring of the first bearing to be assembled. Two inner rings of the first bearing are fixed to the drill point in the up-down direction. The large gear is fixed to the middle of the drill point and engaged with a rack. The rack is slidably mounted on a polished bar in a sleeving mode. The polished bar is mounted in the left clamping plate. The extending-out section, extending out of the left clamping plate, of the rack is engaged with a pinion. The pinion is mounted on an output shaft of a driving motor. The drill point is rotatable, honing is uniform, and the honing effect is good.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a rotatable honing fixture installed on a honing machine. Background technique [0002] Extrusion honing technology is to achieve deburring, polishing, chamfering and changing the surface properties of parts in one process by extruding semi-solid fluid abrasives (composed of polymer carriers and abrasives) through the surface of the workpiece to be processed. It can process multiple surfaces of multiple workpieces at the same time, and can efficiently and economically process surfaces with complex geometric shapes such as narrow slits, intersecting channels, and special-shaped surfaces. The use of extrusion honing instead of manual polishing can greatly reduce labor intensity, improve productivity, and ensure the consistency of product processing. At the same time, extrusion honing has high efficiency, good quality, simple equipment and convenient operation. [0003] At pre...

Problems solved by technology

[0004] In order to overcome the disadvantages of the existing honing jigs that the drill pin is in a fixed position, the honing is uneven, and the honing effect is poor, the present invention provides a drill pin rotatable honing jig with rotatable drill pins, more uniform honing, and better honing effect.
