Float-type hole grinding clamp

Abstract

The invention belongs to clamps, in particular to a float-type hole grinding clamp which is characterized by comprising a bottom plate, pillars, an annular plate, a press plate, a support screw and pin shafts, wherein the pillars are perpendicularly connected with the bottom plate through bolts to form a manger-shaped integral body; the annular plate is in pin connection with the pillars on two sides through the pin shafts; a circular plate for clamping a workpiece is arranged in the center of the circular ring of the annular plate; the adjustable support screw is in bolted connection with the bottom plate; and the circular plate is arranged above the end surface of the adjustable support screw, and is in movable clearance with the end surface of the adjustable support screw. The float-type hole grinding clamp has the benefits that the workpiece can be assembled and disassembled fast through the compressing inclined plane of the press plate; and both the annular plate and the circular plate can move freely, so as to realize the design purpose of 360-degree free floatation; and the hole is ground in a float-type manner, so as to ensure the geometric precision of the hole after processing.

Description

technical field [0001] The invention belongs to fixtures, in particular to a floating hole-grinding fixture used in conjunction with hole-grinding equipment. Background technique [0002] Conventionally, the grinding process of the assembly holes of some sewing machine parts (such as sewing machine oil pumps) all adopts a drill press to install grinding rods, and the operator holds the workpiece in hand to perform "floating" grinding holes. When grinding holes with high precision, it needs to be manually ground on the bench drill. This method can ensure that the hole grinding is qualified. However, the operator's skills and physical strength are relatively high. At the same time, the operator is exposed to kerosene, etc. Grinding liquid can cause discomfort symptoms such as allergies, and manual grinding is inefficient and unstable in quality. The labor intensity of workers is very high, the work efficiency is low, and accidents are prone to occur. The factory has develope...

AI Technical Summary

Problems solved by technology

When grinding holes with high precision, it needs to be manually ground on the bench drill. This method can ensure that the hole grinding is qualified. However, the operator's skills and physical strength are relatively high. At the same time, the operator is exposed to kerosene, etc. Grinding liquid can cause allergies and other discomfort symptoms, and manual grinding is very inefficient and unstable in quality

The labor intensity of workers is very high, the work efficiency is low, and accidents are prone to occur

The factory has developed a hole-grinding jig, which requires frequent tightening of the clamping bolts when mounting the hole-grinding workpiece. The improvement in labor efficiency is not obvious, and the labor intensity of the operator is not reduced.
