Description

A machining device for machining deep grooves on a lathe

technical field

The utility model relates to a processing device for processing deep grooves on a lathe, which belongs to the technical field of mechanical processing equipment.

Background technique

Lathes are often used to process internal and external rotary surfaces, end faces, and various internal and external threads. Because the turning tools used for processing have different shapes, they can process various shapes of rotary surfaces. Of course, they can also cut grooves of various shapes, but for deeper The groove (such as the depth is more than 10mm), the turning tool on the lathe cannot be processed in depth due to structural limitations. Deeper grooves are generally processed on a milling machine, but without a milling machine, the processing of the workpiece will be limited, which will affect the processing efficiency, and the cost of purchasing a new milling machine will be too high.

Contents of the invention

The utility model aims to solve the problem that deep grooves cannot be processed on the existing lathe, and further provides a processing device for milling narrow grooves on the lathe.

The technical scheme that the utility model adopts for solving the problems of the technologies described above is:

A processing device for machining deep grooves on a lathe, which includes a lathe main body and a milling cutter assembly. The lathe main body includes a spindle box and a chuck fixed at the front end of the spindle box. The workpiece is clamped on the chuck. The milling cutter assembly includes a disc milling cutter and a square tool holder. The disc milling cutter is vertically fixed on the square tool holder, and the square tool holder is slidably arranged on the lathe body along the horizontal direction.

Further, a support rod is fixed on the top of the square tool holder, and the disc milling cutter is fixed on the upper part of the support rod.

Further, the disc milling cutter is a three-side disc milling cutter.

Further, the disc milling cutter includes a milling cutter main body, and a first cutting tooth, a second cutting tooth and a plurality of third cutting teeth are processed along the circumferential direction of the milling cutter main body, the first cutting teeth and the second cutting teeth are arranged adjacently and The outer circular surface of the main body of the milling cutter is divided into a superior arc segment and a inferior arc segment, and a plurality of third cutting teeth are uniformly arranged on the superior arc segment.

Further, the angle between the cutting edge on the first cutting tooth and the cutting edge on the second cutting tooth is at least 90 degrees.

Further, the thickness of the disc milling cutter is equal to the width of the deep groove to be machined on the workpiece.

Compared with the prior art, the utility model has the following effects:

Using the teeth of the disc milling cutter can realize the processing of deep grooves, which makes up for the inability of turning tools to process deep grooves. Because there are multiple cutting teeth arranged in the circumferential direction of the disc milling cutter, when machining deep grooves, the cutter can be reinstalled after one cutting tooth wears out, and the other cutting tooth can be replaced to participate in cutting, which saves the time for sharpening the knife. Compared with advanced turning tools, the tool life is longer and the processing efficiency is higher. The technical transformation cost of the present application is low, and the lathe can play the role of a milling machine.

Detailed ways

Specific Embodiment 1: This embodiment is described in conjunction with Fig. 1, 2, a kind of processing device that is used for processing deep groove on lathe, it comprises lathe main body and milling cutter assembly, and described lathe main body comprises headstock 1 and is fixed on The chuck 2 at the front end of the spindle box 1, the workpiece 100 is clamped on the chuck 2, the milling cutter assembly includes a disc milling cutter 3 and a square tool rest 4, and the disc milling cutter 3 is vertically fixed on the square tool rest 4 Above, the square tool holder 4 is slidably arranged on the main body of the lathe along the horizontal direction.

The workpiece 100 is an aluminum part. When processing deep grooves, the aluminum part rotates with the chuck 2 on the main body of the lathe. After the disc milling cutter 3 is installed, it moves laterally. The cutter teeth of the cutter 3 can realize the processing of deep grooves, which makes up for the deficiency that the turning tool cannot process deep grooves. Because the disc milling cutter 3 has a plurality of cutting teeth arranged in the circumferential direction, when processing deep grooves, the cutter can be reinstalled after one cutting tooth wears out, and the other cutting tooth can be replaced to participate in cutting, which saves the time for sharpening the knife, so it is the same as Compared with ordinary turning tools, the tool life is longer and the processing efficiency is higher. The technical transformation cost of the present application is low, and the lathe can play the role of a milling machine.

For example, the size of the deep groove to be processed on the aluminum part is 2.4mm wide, 25mm deep, and the distance between two adjacent deep grooves is 3mm. At this time, the groove with a depth of 25mm cannot be machined with ordinary turning tools. Transformation, changing the turning tool to a disc milling cutter 3 with a diameter of 100 mm and a thickness of 2.4 mm, adjusting the square tool holder 4 to the position to be processed, controlling the rotation of the disc milling cutter 3 along its axial direction, and cutting out a width of 2.4 mm at a time. A deep groove with a depth of 25mm.

The radius of the disc milling cutter 3 is much larger than the depth of the deep groove to be machined, so interference can be effectively avoided during machining.

Disc milling cutter 3 after wearing and tearing, through grinding, its diameter diminishes, can be used for the workpiece 100 deep grooves that processing depth value is on the low side.

The top of the square tool rest 4 is fixed with a support rod 5 , and the disc milling cutter 3 is fixed on the top of the support rod 5 . The support bar 5 is fixed on the top of the square tool holder 4 by welding or bolts, and the upper part of the support bar 5 is horizontally provided with a through hole. Easy to disassemble.

The disc milling cutter 3 is a three-sided cutting disc milling cutter. With such a design, the three cutting edges on the disc milling cutter 3 can realize high-efficiency cutting of the deep groove to be machined. Effectively improve processing efficiency.

The disc milling cutter 3 includes a milling cutter main body 31, and a first cutting tooth 32, a second cutting tooth 33 and a plurality of third cutting teeth 34 are processed along the circumferential direction of the milling cutter main body 31, and the first cutting tooth 32 and the second cutting tooth 33 is arranged adjacent to and divides the outer circular surface of the milling cutter body 31 into a superior arc segment and a inferior arc segment, and several third cutting teeth 34 are evenly arranged on the superior arc segment. The distance between every two adjacent third cutting teeth 34 on the superior arc segment is smaller than the distance between the first cutting tooth 32 and the second cutting tooth 33 on the inferior arc segment. It is equivalent to removing one or two cutting teeth on the outer surface of a disc milling cutter 3 as a chip clearance. Since the disc milling cutter 3 is fixed during the rotation of the workpiece 100, it actually participates in the machining process. Only one first cutting tooth 32 is cutting. During the processing, after the first cutting tooth 32 is worn, the first cutting tooth 32 can be ground off, and the nearest third cutting tooth 34 can be replaced for cutting work.

The angle between the cutting edge on the first cutting tooth 32 and the cutting edge on the second cutting tooth 33 is at least 90 degrees.

The thickness of the disc milling cutter 3 is equal to the width of the deep groove to be machined on the workpiece 100 .
