Description

The hand-held counterbit
Technical field
The utility model relates to a kind of tool for mechanical machining, is specifically related to a kind of hand-held counterbit.
Background technology
I-steel is widely used in various building structure, bridge, vehicle, support, machinery etc., basically all is to occur with large parts, like the beam in the steel frame building.When it further being processed (like boring, chamfering), if use traditional processing method, need use special heavy duty machine tools, anchor clamps, and workpiece weight is all more than tens kilograms, lifting workpiece is time-consuming, require great effort, and productivity effect is low.
The utility model content
Consider the problems referred to above of prior art; An aspect according to the utility model; Disclose a kind of hand-held counterbit, comprised the counterbit body, it is characterized in that; The sleeve of the handle of a knife afterbody that described hand-held counterbit also comprises hand-held lining that the handle of a knife middle part that is contained in the counterbit body is used to hold, be contained in the counterbit body and the handheld tool of power is provided; The handle of a knife matched in clearance of said hand-held lining and counterbit body, the handle of a knife tight fit of said sleeve diameter and counterbit body, the external diameter of said sleeve is connected with the handheld tool that power is provided.
As preferably, said the handheld tool of power is provided is pneumtic impact wrench.
As preferably, the handle of a knife of said counterbit body is a taper shank.
The purpose of the utility model aims to provide a kind of machine tools for the Hole chamfering on the large-scale I-steel.Compared with prior art, the beneficial effect of the utility model is: through with the combining of handheld tool commonly used, obtain a kind of machine tools of large parts chamfering that is easily.
Description of drawings
Fig. 1 shows the structural representation according to the cutter part of the hand-held counterbit of an embodiment of the utility model.
Among the figure, 1-counterbit body, 2-handle of a knife, the hand-held lining of 3-, 4-sleeve.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified, but the embodiment of the utility model is not limited thereto.
A kind of hand-held counterbit as shown in Figure 1 comprises counterbit body 1, and the handle of a knife 2 of counterbit body 1 is a taper shank; The sleeve 4 of handle of a knife 2 afterbodys that the hand-held counterbit also comprises hand-held lining 3 that handle of a knife 2 middle parts that are contained in counterbit body 1 are used to hold, be contained in counterbit the body 1 and handheld tool of power is provided; Handle of a knife 2 matched in clearance of hand-held lining 3 and counterbit body 1, handle of a knife 2 tight fits of sleeve 4 internal diameters and counterbit body 1, sleeve 4 external diameters are connected with the handheld tool that power is provided, and the handheld tool that power is provided is a pneumtic impact wrench.
During use, hold hand-held lining 3 with left hand, the point of a knife of counterbit body 1 is aimed at the hole that needs processing, the right hand is held pneumtic impact wrench and is started, and the range estimation chamfer machining stops to get final product after the needs size.
Provide the pneumtic impact wrench of power to be small processing instrument commonly used, it is the Hole chamfering on the large-scale I-steel that the utility model utilizes this common tool, has improved efficient, has practiced thrift cost.
