Abstract
The utility model discloses a manual burring instrument, including handle, cutter body and blade, wherein, the handle with the cutter body is " T " font and arranges and weld as an organic wholely, the one end of cutter body is fixed in the handle middle part, and the other end is equipped with the blade, the cutter body surface is equipped with an annular at least, just install the flexible protection circle on the annular, the external diameter of guard ring is greater than the external diameter of cutter body. The utility model discloses a burring instrument can prevent the cutter body beat, reduces tool marks, the vibration strip at burring position, makes the deburring more even clean, improves the machining precision of hole.
Description
Technical field
The utility model relates to a kind of deburring tool, and more particularly, it relates to a kind of manual deburring tool.
Background technology
Deburring is exactly remove the thorn or overlap that workpiece formed around working position, and the hole of general firm processing all can be jagged, if removed not in time, directly will have influence on the quality of product.At present, in machinery industry, generally all can produce burr after the processing of partial intersection hole class, due to the reason such as space or machine tool, use equipment of having no idea removes burr, and conventional manual deburring tool deburring.Existing manual deburring tool, simple structure, does not protect bore area, easily causes other working position scratch and affect the machining accuracy in hole in hole during concrete operations.
Utility model content
The technical problems to be solved in the utility model is the above-mentioned deficiency for prior art, provides a kind of structure simple, easy to process, and with the manual deburring tool of safeguard function.
The technical solution of the utility model is such: a kind of manual deburring tool, comprise handle, cutter hub and blade, described handle and described cutter hub are arranged in " T " font and are welded as a whole, one end of described cutter hub is fixed in the middle part of handle, the other end is provided with blade, described cutter hub outer surface is at least provided with an annular groove, and described annular groove is provided with flexible protective circle, and the external diameter of described guard ring is greater than the external diameter of described cutter hub.
As improving further, described cutter hub outer surface is provided with two annular grooves, and described each annular groove is arranged on the cutter hub of blade one end.
Further, described each annular groove axially be arranged in parallel along cutter hub.
Further, described guard ring selects the material of elastomeric flexible.
Compared with prior art, this manual deburring tool has guide effect to the utility model, prevents cutter hub beat, makes removal burr evenly clean, avoids removing burr position and occurs tool marks, chatter phenomena; Further, the guard ring that conductor is provided with has elastomeric flexible function, can protect between cutter hub and hole and touch scrape when rotating, and avoid endoporus machining accuracy to touch scratch, improve the quality of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of manual deburring tool;
Fig. 2 is body portion structural representation.
Wherein: 1-handle, 2-cutter hub, 21-annular groove, 3-guard ring, 4-blade.
Detailed description of the invention
Below in conjunction with the specific embodiment in accompanying drawing, the utility model is described further.
Consult shown in Fig. 1, Fig. 2, the manual deburring tool of one of the present utility model, comprise handle of a knife 1, cutter hub 2 and blade 4, handle 1 is arranged with cutter hub 2 in " T " font and is welded as a whole, one end of cutter hub 2 is fixedly welded in the middle part of handle 1, the other end is provided with blade 4, and blade 4 is welded on the outer surface of cutter hub 2 end.
In the present embodiment, cutter hub 2 outer surface is provided with two annular grooves 21, and each annular groove 21 is arranged on the cutter hub 2 of blade 4 one end.And each annular groove 21 is provided with flexible protective circle 3, the external diameter of guard ring 3 is greater than the external diameter of cutter hub 2, and namely guard ring 3 slightly protrudes from outside cutter hub 2.
In the above embodiments, the quantity of the annular groove 21 that cutter hub 2 is provided with can select 1-4 bar annular groove 21 according to the degree of depth of machining hole, and each annular groove 21 is equidistantly arranged, guard ring 3 adopts elastic soft material.When cutter hub 2 inserts in deep hole, the guard ring 3 protruded from outside cutter hub 2 can play guide effect, prevents cutter hub 2 from inclined shake occurring, and effectively avoids touching when rotating between cutter hub and hole scraping.In addition, each guard ring 3 axially be arranged in parallel along cutter hub 2, cutter hub is rotated more smooth, ensures operating efficiency and quality simultaneously.
Above-described is only preferred embodiment of the present utility model, should be understood that for a person skilled in the art, under the prerequisite not departing from the utility model structure, can also make some distortion and improvement, these all can not affect effect and the practical applicability of the utility model enforcement.
