Abstract

The utility model relates to a mechanical clamp-secured cutter blade, comprising a cutter body and a cutter bar. The utility model is characterized in that, the cutter body is a forming long blade which can reject tips piecewise and use in sequence; the height of the cutter body elevates gradually from exterior to interior, so the inner side surface of the cutter body is a wide surface, the outer side surface of the cutter body is a narrow surface, and the upper end of the cutter body is a slope with higher inner side and lower outer side; a dovetail groove is transversely arranged at the central section of the cutter bar; the cutter body is arranged in the dovetail groove; a through groove is transversely arranged at the middle-upper part of the dovetail groove; a bolt passes from the upper end of the cutter bar to the lower end of the cutter bar through the through groove to control the tightness of the cutter body in the dovetail groove. The utility model has the advantages that, the cutter body and the cutter bar are designed to be separated; the cutter bar can be made by common 45 steel; not only processing is convenient, tool material is also saved; the length of the blade is lengthened to at least three times of traditional blades; the length can be adjusted and be used in sequence by segmentation; when one segment is used up, the blade is adjusted forward for next segment, and the action is carried out successively; the long forming blade can be sharpened repeatedly for a plurality of times to adjust operation.

Description

Machinery clamping type cutoff tool

Technical field

The utility model relates to the machine tools technical field, the particularly a kind of mechanical clamping type cutoff tool that can adjust blade lengths.

Background technology

The cutoff tool that uses is that the latheman is grinding or grinding acquisition by hand on the abrasive machine mostly on tool grinder at present, be of rude workmanship, blade lengths is short, service life is short, the cutter hub of this class cutter and knife bar are an integral body, employed material is the commaterial that cutter hub needs, and therefore cutter material has also been caused very big waste.

The utility model content

The purpose of this utility model provides a kind of with cutter hub and knife bar split design, the mechanical clamping type forming cutting cutter of blade lengths lengthening and segmentation use successively, saving cutter material.

The purpose of this utility model is achieved through the following technical solutions:

A kind of mechanical clamping type cutoff tool, form by cutter hub and knife bar two parts, it is characterized in that described cutter hub is a shaping long blade, this blade can be rejected piecemeal, use successively, the height ecto-entad of described cutter hub is gradually high, makes the cutter hub medial surface form wide, lateral surface forms leptoprosopy, and the cutter hub upper surface is a low inside and high outside inclined-plane; A dovetail groove is laterally driven at described knife bar middle part, and described cutter hub is mounted in it, and the middle and upper part level of dovetail groove is opened a groove, and bolt passes groove to the knife bar lower end from the knife bar upper end, the elasticity of control cutter hub in dovetail groove.

Described dovetail groove inner wide and outer narrow, interior angle forms inclination angle, corresponding cooperation with cutter hub.

The utility model cutter hub and knife bar split design, knife bar can be done with No. 45 common steels, promptly convenient processing, saved cutter material again, the blade lengths lengthening grows at least three times than conventional blades, and length can be adjusted, segmentation is used successively, after using up one section blade is adjusted one section forward, and the like, long blade is shaped, can repeatedly repeat sharpening, adjust and use.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further elaborated:

A kind of mechanical clamping type forming cutting cutter is made up of cutter hub and knife bar two parts, and cutter hub 1 is a shaping long blade, and length is more than three times of common cutoff tool.This blade can be rejected piecemeal, uses successively, and the height ecto-entad of cutter hub 1 is gradually high, makes cutter hub 1 medial surface form wide 1.2, and lateral surface forms leptoprosopy 1.3, and cutter hub 1 upper surface is a low inside and high outside inclined-plane 1.1.A dovetail groove 2.1 is laterally driven at the middle part of knife bar 2, dovetail groove 2.1 inner wide and outer narrows, interior angle forms the inclination angle, match corresponding with cutter hub 1, cutter hub 1 is mounted in it, the middle and upper part level of dovetail groove 2.1 is opened a groove 2.2, passes groove 2.2 to the knife bar lower end by bolt 2.3 and 2.4 from knife bar 2 upper ends, the elasticity of control cutter hub 1 in dovetail groove 2.1.
