Edge grinding device for mechanical tool

Abstract

The invention discloses an edge grinding device for a mechanical tool. The edge grinding device for the mechanical tool comprises a fixed seat, wherein a base is arranged above the fixed seat; an edge grinding device is arranged above the base; the edge grinding device comprises a tool rest, a first rotary body and a second rotary body; the tool rest comprises a tool clamp, a slide body and a fixed frame; a spring is arranged between the tool clamp and the slide body; the first rotary body is composed of a first disc, a first rib column and a second disc; the first disc, the first rib column and the second disc are connected together through screws; the second rotary body comprises a holed disc, a second rib column and a third disc; the second rib column is arranged between the holed disc and the third disc; and a graduated disc is arranged on each of the first disc, the second disc and the third disc. The edge grinding device for the mechanical tool is good in universality, suitable for edge grinding for many mechanical tools, simple to operate, capable of realizing the function of edge grinding for the mechanical tool, and high in safety and reliability, good in shock absorption effect and capable of avoiding the problem of tool breakdown during an edge grinding process.

Description

technical field [0001] The invention relates to the technical field of knife sharpening, in particular to a mechanical knife sharpening device. Background technique [0002] With the development of machinery manufacturing technology, especially CNC machining technology and the wide application of flexible machining, higher requirements are put forward for the tools and their manufacture, which are indispensable for metal cutting. The quality of the tool directly affects the processed The processing quality of parts and its machining efficiency, in order to ensure the processing quality of parts, improve production efficiency, and reduce processing costs, when the tool reaches the value specified in the blunt standard, it should be reground (re-sharpened) before it can continue to be used.

[0002] With the development of machinery manufacturing technology, especially CNC machining technology and the wide application of flexible machining, higher requirements are put forward for the tools and their manufacture, which are indispensable for metal cutting. The quality of the tool directly affects the processed The processing quality of parts and its machining efficiency, in order to ensure the processing quality of parts, improve production efficiency, and reduce processing costs, when the tool reaches the value specified in the blunt standard, it should be reground (re-sharpened) before it can continue to be used. The sharpening of mechanical tools is not only the last process in the tool manufacturing process, but also a process that must be carried out for multiple regrinding of the tool. The sharpening of the tool determines the final shape and geometric accuracy of the cutting part of the tool, and is the key to ensure the cutting performance of the tool. And the key to product quality, the turning tool is a very common mechanical cutting tool, which can be used to process the outer circle, turning section and boring on the lathe. In most machining factories, the lathe CNC lathe has been widely used. application, turning tools are used more frequently, turning tools, like other mechanical tools, will become blunt after a period of cutting, and must be reground before use, otherwise, the turning tool will be scrapped, so the weight of the turning tool Grinding workload is very large

[0003] At present, more than 98% of the sharpening of spiral tooth end mills in my country is carried out on M6020 or its variants and improved ordinary universal tool grinders or manual grinding. The grinding quality depends on the rigidity and accuracy of the machine tool itself. , also mainly depends on the skill and intuition of the operator, so the disadvantages of this regrinding method are: (1) poor versatility, a grinding machine can only grind one type of mechanical tool; (2) manual grinding tool has Certain danger, once a mistake occurs, it will cause a great personal accident; (3) There is no buffer and shock absorption device, and the tool is prone to shattering during the sharpening process of mechanical knives, and the safety performance is poor
