Abstract
The invention relates to a groove-cutting tool which can fast cut and grind a groove and conveniently adjust the groove-cutting depth. The tool body is internally provided with T-shaped multi-step passageways; a toolbar is a multi-step toolbar; the multi-step toolbar is inserted into the multi-step passageways in the tool body; the toolbar in a second-step passageway is provided with a spring; keys are arranged between the toolbar in a third-step passageway and the inner wall of the third-step passageway at intervals; a flange housing is sleeved on the outer wall of the T-shaped multi-step passageways by a bearing housing; a blank cap passes through the toolbar to be connected with the flange housing; a tool array is arranged in the T-shaped tool array hole of the tool body, and the low end of the tool array contacts with the front end of the toolbar; the spring is sleeved on the tool array; and the upper end of the tool array is provided with a tool array cap. The groove-cutting tool has the advantages that the tool array is in a nonrigid stress groove-cutting state in the process of operation, thus avoiding the tool array from being damaged; and the rotary groove-cutting effect is realized, and the dynamic feed can be finished in the rotary groove-cutting process.
Description
Technical field
The present invention relates to a kind of can cutting fast and cut groove, can conveniently adjust again cut groove depth cut the groove cutter, belong to and cut the groove cutter and make the field.
Background technology
CN 2031738Y, title " U-shaped cuts the groove cutter ", this device comprises handle of a knife and cutter head, and its handle of a knife is assembled by fastening bolt by the cutter hub and the rotary head of band scale, and the cutter head of U-shaped wedge-like utilizes locating piece and screws clamp in rotary head.This device can be installed on lathe, milling machine or the planer, and the width of groove, the degree of depth, spacing and shape are once cut the type of being whittled into as requested, can process straight trough, chevron-notch, prismatic groove, and this apparatus structure is simple, and it is time saving and energy saving to process, non-environmental-pollution.Its weak point: the one, during making in the course of the work, the cutter head of U-shaped wedge-like is in the rigidity stress, easily damaged by workpiece; The 2nd, both can't realize rotating and cut groove, also can't cut and finish dynamic feed in the groove in rotation.
Summary of the invention
Purpose of design: on the basis of existing background technology, design a kind of can cutting fast and cut groove, can conveniently adjust again cut groove depth cut the groove cutter.
Design: in order to realize above-mentioned purpose of design.1, having the design of the multistage step passage of T font in the cutter hub, is one of technical characterictic of the present invention.The purpose of doing like this is: because knife bar is multistage step knife bar, multistage step knife bar inserts in the multistage step passage in the cutter hub and is with spring on the knife bar in the two stage steps passage, this spring makes between blade row and the knife bar and is resilient engagement, can make blade row in cutting the groove process, be in stressed elastic stage, thereby avoid in the cutting process workpiece the damage of blade row.2, flange seat is two of a technical characterictic of the present invention by the design of bearing holder (housing, cover) on the multistage channel outer wall of T font.The purpose of doing like this is: it not only makes between blade row and the knife bar and has realized non-rigid the cooperation, and has realized that the cutter hub rotation cuts the purpose of groove, and the degree of depth of cutting groove can be finished in dynamically.3, knife bar front end chamfer length is three of a technical characterictic of the present invention greater than the design of blade row lower end chamfer length.The purpose of doing like this is: by cooperating of knife bar front end inclined-plane and inclined-plane, blade row lower end, can control the depth of cut of blade row effectively, reposefully, thereby be implemented in the rotation steadily, the effective purpose of feed.
Technical scheme: a kind of groove cutter that cuts, have the multistage step passage of T font in the cutter hub, knife bar is multistage step knife bar, multistage step knife bar inserts in the multistage step passage in the cutter hub and is with spring on the knife bar in the two stage steps passage, is equipped with key between its knife bar and vias inner walls in three grades of step passages, flange seat by bearing holder (housing, cover) on the multistage channel outer wall of T font, stifle passes knife bar and is connected with flange seat, blade row is positioned at the T font blade row hole and the blade row lower end of cutter hub and touches mutually with the knife bar front end, be with spring on its blade row, the blade row upper end is provided with the blade row lid.
The present invention compares with background technology, and the one, realized that blade row is in the non-rigid stressed groove state that cuts in the course of work, has avoided blade row to be damaged; The 2nd, both realized rotating and cut groove, also realized cutting the purpose of finishing dynamic feed in the groove in rotation.
Description of drawings
Fig. 1 is the structural representation that cuts the groove cutter.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of groove cutter that cuts, have the multistage step passage of T font in the cutter hub 8, knife bar 1 is multistage step knife bar, multistage step knife bar inserts in the multistage step passage in the cutter hub and is with spring 9 on the knife bar in the two stage steps passage 1, in three grades of step passages, be equipped with key 10 between its knife bar 1 and vias inner walls, flange seat 3 is enclosed within on the multistage channel outer wall of T font by bearing 4, stifle 2 passes knife bar 1 and is connected with flange seat 3 by screw 13, blade row 5 is positioned at the T font blade row hole and blade row 5 lower ends of cutter hub 8 and touches mutually with knife bar 1 front end, be with spring 7 on its blade row 5, blade row 5 upper ends are provided with blade row lid 6.
The multistage step passage of described T font is with round nut 11 and bearing 4 is spacing.Be with round nut 12 on the described knife bar 1.
Described blade row 5 lower ends are the inclined-plane with the face that touches mutually of knife bar 1 front end, and the fit angle on two inclined-planes makes blade row 5 be in upright state just.
Described knife bar 1 front end chamfer length is greater than blade row 5 lower end chamfer lengths, and inclined-plane, blade row 5 lower end is half of its diameter, and promptly 1/2 of blade row 5 lower ends is the inclined-plane, and remaining 1/2 is the amount that knife bar 1 promotes blade row 5 feeds.
What need understand is: though the foregoing description is to the mentality of designing of the present invention detailed text description of contrasting; but these text descriptions; just the simple text of mentality of designing of the present invention is described; rather than to the restriction of mentality of designing of the present invention; any combination, increase or modification that does not exceed mentality of designing of the present invention all falls within the scope of protection of the present invention.
