Embodiment 1

[0048] Such as figure 2 , image 3 As shown, a kind of arc-shaped blade grinding device of this embodiment mainly completes the figure 1 The grinding process of the arc-shaped blade blade shown in this circular-arc-shaped blade has a circular mounting hole 710 at one end of the knife body 700 for installing the blade on the corresponding cutting equipment, and the knife body 700 is close to the mounting hole 710 There is a positioning hole 720 at the position of the blade, which is used for positioning when installing the blade; the other two sides of the blade body 700 are the blade side 730 and the blade back side 740 respectively, both of which are arc-shaped, but not concentric, and gradually retract toward the front end of the blade. narrow, and there are knife teeth 731 distributed on the arc segment of the blade side 730, and the front and back sides of the knife teeth 731 are blade slopes 732. In actual production, the blade slope 732 needs to be ground, and the blad...

Embodiment 2

[0060] A kind of arc-shaped grinding method of the present embodiment, it adopts the grinding device among the embodiment 1 to such as figure 1 The arc-shaped insert shown is ground, grinding the bevel 732 of the edge. The specific steps of the operation will be described in detail below.

[0061] 1. Blade installation

[0062] Install the arc-shaped blade to be ground on the workbench assembly 400 . Specifically: first, align the mounting hole 710 and the positioning hole 720 of the arc-shaped blade with the fixed shaft 421 and the positioning pin 422 on the turntable 420 respectively, put down the arc-shaped blade, and position it; then, place the pressing spring Sleeve on the fixed shaft 421, tighten the compression nut, and fix the arc-shaped blade, and then complete the installation of the blade.

[0063] 2. Grinding angle adjustment

[0064] First, select three grinding wheels 330, which are respectively rough grinding wheels, semi-finishing grinding wheels and grind...

Abstract

The invention discloses an arc edge grinding device, and belongs to the field of cutter sharpening equipment. The arc edge grinding device comprises a base, a grinding wheel module, a worktable moduleand a swing mechanism; the swing mechanism is arranged on the base, is connected with the grinding wheel module, and is used for driving the grinding wheel module to perform the arc swing; the swingmechanism comprises a power module and a swing module; the swing module comprises a slide base arranged above the base, a swing base connected with the grinding wheel module, and a swing spring; a driven shaft is arranged on the slide base; the swing base is fixed on the driven shaft; one end of the swing spring is connected with the slide base, and the other end is connected to one side of the swing base; and the power module is used for driving the driven shaft to perform intermittent rotation. The device can finish grinding of an arc edge surface on one side of an arc blade through once clamping; the grinded edge surface is better in arc; and the edge angle consistency is better, so that the grinding efficiency and quality are greatly improved.

Description

technical field [0001] The invention belongs to the field of cutter grinding equipment, and relates to a device capable of grinding the blade of an arc-shaped knife, more specifically, to a grinding device for an arc-shaped blade. Background technique [0002] Grinding is widely used and is one of the main methods for precision machining of machine parts. A grinder is a machine tool that uses abrasive tools, such as grinding wheels, to grind the surface of a workpiece. The grinding machine can process materials with higher hardness, such as hardened steel, cemented carbide, etc.; it can also process brittle materials, such as glass and granite. The grinding machine can be used for grinding with high precision and small surface roughness, as well as high-efficiency grinding, such as powerful grinding. [0003] In the production process of alloy steel or ceramic blades, grinding is an essential and important process. Only rough grinding and fine grinding can produce smooth, ...
