Description

Grinding attachment of a cutting tool making preparations for automatic system

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grinding machine of a cutting tool configured to be operated by an automatic system for precisely finishing a cylindrical cutting tool. In particular, the outer peripheral surface is ground after automatically chucking and firmly supplying a cutting tool to be processed. It is automatically discharged and loaded, and when only the object to be supplied is supplied, it is possible to perform unmanned grinding operation automatically, thereby improving productivity, reducing production time, unnecessary processes and operations, and reducing cost and labor costs. The present invention relates to a grinding device for a cutting tool with an automatic system that can greatly reduce the back.

In general, cutting tools are cutting tools used for cutting work, such as lathes or cutting tools such as drilling, milling and tapping machines, and other machine tools, Tools such as milling cutters, drills, hobs, reamers, taps, etc. are all or partially hardened at relatively room and high temperatures, such as special steel for tools and carbon tool steel, high speed steel, or cemented carbide. It is made of rigid material with characteristics such as high, high wear resistance, toughness and easy heat treatment.

Since the cutting tool is a tool for easily cutting a workpiece to be machined, a key part of the cutting tool is at the cutting edge. Therefore, the cutting tool is basically a high quality cutting tool according to the cutting edge angle, that is, the angle and clearance angle of the various surfaces, the blade tip angle, shape and shape, as well as the finishing operation for precise grinding and finishing of the cutting edge. Is done.

The manual grinding device of a conventional cutting tool for grinding a workpiece, which is a cylindrical cutting tool as described above, will be briefly described with reference to FIGS. 7 to 9A and 9B.

Grinding work according to the shape and shape of the workpiece (W), first, the workpiece (W) of the grinding target is formed in the shape of a circular rod formed with a polygonal holder fastening surface (W1) at one end, the workpiece gripper ( 20) there is a work method using a plurality of chip discharge grooves (W2) formed in the longitudinal direction at one end of the object to be ground, is set to be coupled to the rotary face plate 11 of the headstock (10) to be rotated together There is a work method to be performed by replacing the drive pins 12 made of a shape.

First, the work method using the workpiece holding tool 20 is inserted and placed in the opening receiving groove 21 while maintaining a predetermined angle on one surface, and then select the butterfly bolt 22 formed to be tightened and loosened at one end. By adjusting and firmly fixing the workpiece (W), and then positioned between the spindle center 13 of the main shaft 10 and the tailstock center 31 of the tailstock 30 and then adjust the tailstock 30 The chuck is fixed by being fixed to the center of both end faces of the workpiece (W) positioned at both ends of the main shaft and the tailstock centers (13, 31).

Here, the driving pin 12 inserted into and fixed to the rotating face plate 11 of the main shaft 10 is in contact with the workpiece gripper 20, and the driving force of the rotating face plate 11 is the driving pin 12 and the work piece. Power is transmitted to the workpiece (W) through the gripper 20 is rotated together to form a grinding work.

Second, the work method of selecting and replacing the driving pins 12 is to adjust the tailstock 30 by positioning the workpiece (W) between the spindle center 13 and the tailstock center 31 to adjust the workpiece (W). The other end of the driving pin 12, which is bent at approximately right angles and fixed to the rotary face plate 11 of the headstock 10, is fixed to the chip discharge groove W2 of the workpiece W. When the rotary face plate 11 is rotated, the workpiece W chucked between the centers is also rotated together, and the grinding wheel 40 is also rotated so that the grinding work is performed manually.

However, in the conventional manual grinding device, since the entire grinding processing process is set by the operator, the grinding process is performed after the assembly and manipulation by the operator, the time and unnecessary processes and operations of the production unit of the product increase according to the grinding operation. As a result, production efficiency is lowered, workability and productivity are lowered, production costs are increased due to expensive production maintenance and labor costs, and mass production of products is not possible in a short time, and the precision of grinding is reduced. There was a problem that the defect rate of the product is increased and the product quality and reliability of the product are deteriorated together.

Therefore, the present invention has been made in order to solve the fundamental problems of the prior art, the object of which is to be configured to be automatically loaded and discharged at the same time after the grinding process of the outer peripheral surface after the automatic supply and chucking of the cylindrical workpiece Fully automatic unmanned grinding can be performed quickly, improving product productivity, reducing production unit time, unnecessary processes and operations, significantly reducing production costs and labor costs, and enabling mass production in a short time. To provide a grinding device for cutting tools with automated systems.

Therefore, the workpiece (W) is elastically supported at each of the tongs 431 of the tong block 430 and at the same time positioned between the main shaft center 312 and the mandrel center shaft 510 is firmly fixed.

Since the work W is elastically supported by the automatic system and chucked in a fixed state, the work W is smoothly ground by the grinding wheel 700.

When the workpiece W is finished grinding, the spindle cylinder 330 of the spindle-drive unit 300 is operated again, so that the cylinder shaft 320 connected to the second push rod 331 is in a horizontal state. Direction retreat in the direction, and the other end of the crank arm 420 of the workpiece chucking unit 400 moves along the contact guide surface 341 when the slide ring 340 located at the tip of the spindle shaft 310 is retracted. When the crankshaft 412 is also rotated naturally, the tong block 430 is expanded and the cardiac pressure center shaft 510 being pressed against the workpiece W by the operation of the cardiac compression cylinder 520 is retracted. Since is completely released, the processed workpiece (W) is dropped directly below, which is moved along the discharge guide portion 600 again and are sequentially stacked on a predetermined loading table.

Therefore, it is possible to quickly perform the grinding processing process by the automatic system of the workpiece (W) by unmanned easily and conveniently a large amount of the workpiece (W) in a short time.

According to the present invention as described above, the automatic cutting process of the cylindrical cutting tool is possible, and according to the unmanned grinding operation, the time and unnecessary processes and operations of the production unit of the product are shortened or omitted, thereby maximizing the efficiency of the production process and the productivity of the product.
