Straight knife sharpener

Abstract

The invention discloses a straight knife sharpener comprising a lathe body, a grinding head assembly and a workbench assembly. Two lathe body linear guide rail pairs are arranged on the top face of the lathe body. The grinding head assembly is supported on the lathe body slidably by a grinding head movable base through the two lathe body linear guide rail pairs. A grinding head motor is installedon a grinding head sliding seat through a grinding head installing plate, and the grinding head sliding seat is driven by a grinding head feed motor and is slidably supported on the grinding head movable base. Position sensors are arranged on the grinding head movable base through vertical and transverse moving sliding seats and a detection driving device. The workbench assembly is located betweenthe left and right lathe body linear guide rail pairs. A workbench is supported on a lathe body in an oscillatory mode. A workpiece locating plate and a workpiece locating push arm are arranged on the two sides of a workbench body correspondingly. A grabbing manipulator is further slidably supported on the lathe body through the lathe body linear guide rail pairs and a side face linear guide railpair. Automatic feeding and discharging and automatic control of grinding precision can be achieved through the straight knife sharpener, a straight knife plane and a cutting edge bevel can be groundthrough one time of clamping, and production efficiency is high.

Description

technical field [0001] The invention relates to a metal cutting machine tool, in particular to a grinding machine used for grinding the plane and edge of a sheet-shaped straight knife. Background technique [0002] Straight knives are a kind of sheet-shaped and long strip-shaped knives, which are widely used in papermaking, printing, textile, fiber, food, forestry, plastic, wood and other industries. In the manufacturing process of the straight knife, the plane of the knife body and the inclined surface of the edge of the straight knife must be ground to ensure the sharpness and straightness of the knife edge and the consistency of the size. Usually the grinding of straight knife is carried out by surface grinder or special straight knife grinder similar to surface grinder. To complete the grinding process, the straight knife can be placed on the electromagnetic chuck of the workbench for direct grinding when the plane of the cutter body is ground. The grinding of the cutt...

Problems solved by technology

Usually the grinding of straight knife is carried out by surface grinder or special straight knife grinder similar to surface grinder. To complete the grinding process, the straight knife can be placed on the electromagnetic chuck of the workbench for direct grinding when the plane of the cutter body is ground. The grinding of the cutting edge requires two clampings, the production efficiency is low, and the quality is not easy to guarantee; and during the grinding process, it is necessary to stop the machine and manually measure the relevant dimensions of the straight knife to be ground, and determine the feed amount according to the measurement results until the desired value is reached. The required size and precision, such a precision control method is greatly affected by the technical level of the operator, measurement errors, etc., the machining accuracy is difficult to guarantee, and the efficiency is also very low; The loading and unloading needs to be done manually by the operator, which is labor-intensive, slow in handling and low in efficiency
