CN2623389Y - Cutting tool for planer bar and dadoing - Google Patents

Abstract

The utility model discloses a cutting tool for planer bar and dadoing, comprising a cutter holder and a cutter blade. The center of the cutter holder is axially provided with a shaft hole, the cutter holder is provided with a support body which is symmetrical to the center, the cutter blade is fixed on the support body, and a positioned structure is arranged between the cutter blade and the support body for positioned the cutter blade. The installation among the planer bar as well as the cutter holder and the cutter blade of the dadoing cutter of the utility model adopts a structure of positioned installation, so after the planer bar and the dadoing cutter blade is worn out, the planer bar or the dadoing cutter blade are detached to be made a planar polishing and then is reassembled, thereby, the distance between the most front end of the edge on the blade and the center of the cutter holder can be constant, thereby, the time of the installation can be greatly saved, the working efficiency can be improved and the service life of the cutter blade can also be prolonged. In order to convenient the processing of the cutter holder, the cutter holder can also be divided into three parts to be respectively processed and then to be fixed together through the bolts.

Description

A kind ofly be used to dig bar, channeling cutter

Technical field

The utility model belongs to the cutter that planer is used, and relates in particular to a kind of special use plane bar, channeling cutter that is used to process pencil shaft and pencil-lead groove.

Background technology

Pencil is a kind of stationery that we often use, the pencil of the various moulding of Xiao Shouing in the market, its penholder all will be through digging bar and channeling two procedures, and being shaped as of the plane planing tool that bar, channeling adopted is cylindrical, this cylindrical planing tool is mounted in the middle of two clamping plate, and by bolt they are fixed tightly in together, be installed in again in the rotating shaft of planer afterwards.When planer was worked, planing tool rotated at a high speed with the planer rotating shaft, and the plank that is opposite to planing tool below planes, because the blade of planing tool is thinner, every work will be unloaded planing tool about 1 hour and polish, and then planing tool and baffle plate be installed again.Because planing tool is through after polishing, the height and the angle of its blade change to some extent, cylindrical because of being shaped as of planing tool again, there is not location structure between planing tool and the baffle plate again, so need readjust the position of planing tool when installing, and planing tool needs more accurate location in producing, and has therefore just increased mounting hardness, has also reduced operating efficiency simultaneously.If planing tool angle adjustment in the process of reinstalling is improper, the product depth size that digs is sub-standard, and very easily damages the blade of planing tool.

Summary of the invention

The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of rational in infrastructure, easy for installation, planing tool is not easy to wear and the plane bar of long service life, channeling cutter.

The utility model is achieved by the following technical programs: a kind ofly be used to dig bar, channeling cutter, comprise knife rest and blade, axially there is an axis hole center of described knife rest, knife rest is provided with the symmetrical supporter in center, described blade is packed on the supporter, and is provided with the location structure that makes the blade location between blade and the supporter.

Described supporter and described knife rest are integral.

There is a groove supporter end near the blade place.

Described location structure is to be provided with the reference column that is connected as a single entity with it near the knife rest both ends on the supporter with on the contacted plane of blade, also be provided with the screwed hole that is used for fixing blade on the plane of supporter, described blade is provided with locating hole and and the corresponding through hole in screwed hole position that matches with the blade reference column.

Described blade front end has a tapered plane, and the center line of described locating hole parallels with this tapered plane.

Described knife rest is made up of three parts vertically.

The length of described pars intermedia is greater than both ends, and described blade reference column is positioned on the supporter at both ends.

Because plane bar of the present utility model, the structure of location and installation has been adopted in the knife rest of channeling cutter and the installation between the blade, parallel with the tapered plane of blade front end because of the locating hole that matches with the blade reference column on the blade again, and the blade reference column on the knife rest parallels with locating hole, so when digging bar, behind the channeling blade abrasion, pull down the plane polishing is carried out in the bottom surface, then re-assembly again, can keep the constant apart from the distance at knife rest center foremost of blade upper knife edge like this, the time of installation can be saved greatly thus, increase work efficiency, also can prolong the physical life of blade.For the ease of the processing of knife rest, also knife rest can be divided into three parts and process respectively, by screw this three part is solidly installed again.

The specific embodiment

Embodiment 1: as shown in the figure, plane bar of the present utility model, channeling cutter comprise knife rest 4 and blade 1, and axially there is one axis hole the center of knife rest 4, and the outside dimension of rotating shaft matches on the size of this shaft hole diameter and the planer.Symmetrical and supporter 2,2` that be connected as a single entity with knife rest 4 with the center are arranged on the knife rest 4, and supporter 2,2` is last is provided with blade reference column 3,3` that makes blade 1 location and the screwed hole that is used for fixing blade 1 near knife rest 4 both ends.For the ease of going out to cut, near blade 1 place one groove 5,5` are arranged in the end of supporter 2,2`.Blade 1 front end shown in the figure has a tapered plane M, and the locating hole 6 on the blade 1, the center line of 6` parallel with this tapered plane M.Because of blade 1 in use needs often the plane polishing to be carried out in the bottom surface, when the thickness of blade 1 during less than original size, for keeping the constant apart from the centre distance of knife rest 4 foremost of blade 1 upper knife edge, so blade reference column 3,3` also should parallel with the tapered plane M on the blade 1.Also be provided with on the blade 1 in addition and the corresponding through hole 7 in screwed hole position.

Embodiment 2: the structure of present embodiment is substantially the same manner as Example 1, it does not exist together, be connected as a single entity at embodiment 1 intermediate slide 4 and supporter 2,2`, processing for the ease of this part structure, knife rest 4 and supporter 2,2` can be divided into three parts vertically and process respectively, be pars intermedia 4b and both ends 4a, 4c, wherein the length of pars intermedia 4b is greater than both ends 4a, 4c, and blade reference column 3,3` then lay respectively on the supporter of both ends 4a and 4c.

During installation the locating hole on the blade 16,6` are aimed at blade reference column 3,3` on supporter 2, the 2`, blade 1 is placed on the supporter 2,2` of knife rest 4, by screw blade 1 is fixed on the knife rest 4 again, at last on two end faces of the cutter that assembles, load onto clamping plate, and it is installed in the rotating shaft of planer by clamping plate.

The mode of said fixing blade also can adopt other fastening method.

In the process of pencil shaft, the profile of pen core groove and penholder is to adopt two kinds of blades that structure is different, shown in Figure 5 is the structure of channeling blade 1, the blade that a plurality of uniform projectioies are arranged on the tapered plane of 1 front end of blade shown in the figure, and the width of channeling blade 1 blade can be decided according to the size in pen core cross section.Shown in Figure 7 is the structure of digging bar blade 1, and a plurality of uniform grooves are arranged on the tapered plane of the front end of the blade 1 shown in the figure, and the shape of this groove can be processed into multiple shape according to the moulding of penholder, can produce a lot of different penholders like this.
