Abstract

The utility model relates to a milling cutter, wherein the milling cutter is arranged at the middle part of a step-shaped cutter bar; the cutter bar at the left side of the milling cutter is provided with a threaded end that is adaptively connected with a cover-shaped nut and props against a connecting sleeve sheathed on the cutter bar; the cutter bar at the right end of the milling cutter is provided with a retaining sleeve which is fixed with two rolling bearings; outer walls of the two rolling bearings are provided with supporting outer sleeves, the tail part of the supporting outer sleeve is provided with a check ring that is connected in a groove of the supporting outer sleeve in a clamping manner; the cutter bar at the right end of the supporting outer sleeve is provided with a groove; and an adjusting sleeve is fixed by adjusting a bolt. The milling cutter has simple structure, reasonable design, time-saving and labor-saving properties, high deburring efficiency, and balanced force application. The size of a pipe mouth exposed out of a pipe plate can be adjusted and is uniform and consistent, thus protecting the pore wall of the pipe from being scratched.

Description

Mill flat cutter
Technical field
The utility model relates to a kind of flat cutter that mills, and it is applicable to the finishing of exposing the tube sheet part mouth of pipe behind the expand tube of all kinds of heat exchangers specifically.
Background technology
At present, in heat exchanger production and transformation process, the mouth of pipe is often jagged after the Pipe Cutting.Need remove burr with milling tools by manual, labour intensity is big in the removal process, wastes time and energy.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, time saving and energy saving, remove burr efficient high mill flat cutter.
In order to achieve the above object, the technical solution adopted in the utility model is: milling cutter is equipped with in the middle part at step-like knife bar, threaded end head and acorn nut are matched on the knife bar of its left-hand portion, and lean the adapter sleeve that is sleeved on the knife bar, on the knife bar at milling cutter right-hand member position maintainance set is arranged, be fixed with two rolling bearings on it, on two rolling bearing outer walls, support sleeve is installed, be equipped with on its afterbody in the groove that back-up ring is connected in support sleeve, on the knife bar of support sleeve right-hand member, be provided with groove, by adjusting the fixing cover of adjusting of screw.
The utility model has the advantages that:
Simple in structure, reasonable in design, time saving and energy saving, remove burr efficient height, stress equalization.The mouth of pipe exposes the size adjustable of tube sheet, and uniformity, and protection pipe hole wall is not scratched.
Description of drawings
Fig. 1 is the utility model structural representation;
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model is equipped with milling cutter 3 in the middle part of step-like knife bar 4, threaded end head and acorn nut 1 are matched on the knife bar 4 of its left-hand portion, and lean the positioning sleeve 2 that is sleeved on the knife bar 4, on the knife bar 4 at milling cutter 3 right-hand member positions maintainance set 10 is arranged, be fixed with two rolling bearings 5 on it, on two rolling bearing 5 outer walls, support sleeve 6 is installed, be equipped with on its afterbody in the groove that back-up ring 9 is connected in support sleeve 6, on the knife bar 4 of support sleeve 6 right-hand members, be provided with groove, by adjusting the screw 7 fixing covers 8 of adjusting.
It is to be used as power with electric hand drill that the utility model mills flat cutter; be connected with it by jockey and finish cutting. milling flat cutter is by cutter hub; adjusting device two parts are formed. and wherein cutter hub is by knife bar 4; milling cutter 3 positioning sleeves 2 are formed with the acorn nut 1 that is contained in left end. and cutter hub plays the milling effect. and adjusting device is by adjusting screw 7; maintainance set 10; rolling bearing 5 is by pad and back-up ring 9; support sleeve 6 is formed. and adjusting device is used for determining that the mouth of pipe exposes the size of tube sheet. at first unclamps and adjusts screw 7; adjust the milling cutter blade apart from support sleeve 6 end face distances; this size is the size that the mouth of pipe exposes tube sheet; be generally 1～3mm; tighten then and adjust screw 7. in the milling cutter 3 insertion mouths of pipe; open electric drill; the cutter hub rotation makes milling cutter 3 carry out milling; treat to finish when support sleeve 6 end faces support to tube sheet. the utility model three sword millings; stress equalization. the mouth of pipe exposes the size adjustable of tube sheet, and uniformity. positioning sleeve 2; knife bar 4 protection pipe hole walls are not scratched.
