Abstract
A kind of electric hammer drill of quick chip removal, including drill body, drillstock, drill, the drill body is structure as a whole with drillstock, the drill is entrenched in the end of drill body, the drill body offers the chip space of spiral trend along surface perimeter, drill body forms corresponding blade along chip space, the chip space is trapezoidal groove body, and the angle between blade and the central axis of drillstock is obtuse angle, the drillstock offers the gain and straight trough for connecting with electric hammer along surface perimeter, and the straight trough extends to the end face of drillstock, and the gain and straight trough are spaced apart.The utility model changes the semicircle slot structure of traditional chip space, trapezoidal groove body is arranged in chip space, and the angle between blade and the central axis of drillstock is obtuse angle, so that the slot bottom width of chip space is less than width of rebate, increase solid capacity, to reach the effect of quick chip removal, reduce that accumulated plugging leads to the idle abrasion of alloy drill in use in chip space because of break flour, prolongs its service life.
Description
Technical field
The utility model relates to electric hammer drill field, the electric hammer drill of espespecially a kind of quick chip removal.
Background technique
Hard alloy electric hammer drill main body use superior alloy steel, matched with various electric hammers, be suitable for concrete,
It drills on the hard building materials such as brick, is building, the boring bar tool that a kind of purposes is wide, high-efficient in industry is installed.Electric hammer drill makes
With in the process by the impact of pulsating, biggish torsion need to have certain obdurability, at the same surface to have it is higher wear-resisting
Property, highest attention of the service life of electric hammer drill by users.
Referring to Fig. 1, the chip space of existing electric hammer drill is semi-circular groove profile.It is single due to present electric hammer power increase
Type half slot and dimorphism half slot are in chip removal effect, it may appear that chip removal leads to the idle abrasion of alloy not in time, thus is using
There is decrease to a certain extent on service life.
Summary of the invention
To solve the above problems, the utility model provides and a kind of reduces the quick chip removal that abrasion, structure is simple, is easy to be transformed
Electric hammer drill.
A kind of in order to achieve the above purposes, the technical solution adopted by the utility model is: electric hammer drill of quick chip removal, including
Drill body, drillstock, drill, the drill body are structure as a whole with drillstock, and the drill is entrenched in the end of drill body, and the drill body is along table
Face circumference offers the chip space of spiral trend, and drill body forms corresponding blade along chip space, and the chip space is trapezoidal groove body,
And the angle between blade and the central axis of drillstock is obtuse angle, the drillstock is offered along surface perimeter for connecting with electric hammer
Gain and straight trough, the straight trough extends to the end face of drillstock, and the gain and straight trough are spaced apart.
Specifically, the angle between the blade and the central axis of drillstock is 120 ° -150 °.
Specifically, the gain and straight trough are disposed as two, and two gains along drillstock diametrically, two straight trough edges
Drillstock is diametrically.
Specifically, the gain is semicircle groove body, and the straight trough is trapezoidal groove body.
The utility model has the beneficial effects that: the utility model changes the semicircle slot structure of traditional chip space, will arrange
It considers slot to be worth doing and trapezoidal groove body is set, and the angle between blade and the central axis of drillstock is obtuse angle, so that the slot bottom width of chip space
Less than width of rebate, solid capacity is increased, to reach the effect of quick chip removal, reduces to accumulate in chip space because of break flour and block up
Plug leads to the idle abrasion of alloy drill in use, prolongs its service life.And interval is provided on drillstock surface
The gain and straight trough of distribution, wherein straight trough is directly blocked when drillstock is packed into electric hammer mounting hole, and gain is packed into electric hammer peace in drillstock
Dress is blocked behind hole by collet, and by using while both gain and straight trough, realization drill bit and electric hammer are stably connected with.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing chip space；
Fig. 2 is the overall structure diagram of the utility model；
Fig. 3 is the drillstock sectional view of the utility model.
Drawing reference numeral explanation: 1. drill bodies；2. drillstock；3. drill；4. chip space；5. blade；6. gain；7. straight trough.
Specific embodiment
Please refer to Fig. 2-3, a kind of electric hammer drill of the utility model about quick chip removal, including drill body 1, drillstock 2, drill
3, the drill body 1 is structure as a whole with drillstock 2, and the drill 3 is entrenched in the end of drill body 1, and the drill body 1 is opened along surface perimeter
Chip space 4 equipped with spiral trend, drill body 1 form corresponding blade 5 along chip space 4, and the chip space 4 is trapezoidal groove body, and
Angle between blade 5 and the central axis of drillstock 2 is obtuse angle, and the drillstock 2 is offered along surface perimeter for connecting with electric hammer
The gain 6 and straight trough 7 connect, the straight trough 7 extend to the end face of drillstock 2, and the gain 6 and straight trough 7 are spaced apart.
In the present embodiment, the steel of the drill body 1 are 40Cr, and the material of the drill 3 is import alloy.
The utility model changes the semicircle slot structure of traditional chip space 4, and trapezoidal groove body, and blade 5 is arranged in chip space 4
Angle between the central axis of drillstock 2 is obtuse angle, so that the slot bottom width of chip space 4 is less than width of rebate, the row of increasing
Bits amount reduces that accumulated plugging causes alloy drill 3 to make in chip space 4 because of break flour to reach the effect of quick chip removal
With idle abrasion in the process, prolong its service life.And the gain 6 and straight trough being spaced apart are provided on 2 surface of drillstock
7, wherein straight trough 7 is directly blocked when drillstock 2 is packed into electric hammer mounting hole, and gain 6 passes through after drillstock 2 is packed into electric hammer mounting hole
Collet blocks, and by using while both gain 6 and straight trough 7, realizes being stably connected with for drill bit and electric hammer.
In the present embodiment, the angle between the blade 5 and the central axis of drillstock 2 is 120 ° -150 °.
When angle between blade 5 and the central axis of drillstock 2 is excessive, it will lead to 5 rapid wear of blade, reduce instead
Chip removal efficiency.Preferably, the angle between blade 5 and the central axis of drillstock 2 is 130 ± 5 °.
In the present embodiment, the gain 6 and straight trough 7 are disposed as two, and two gains 6 along drillstock 2 diametrically, two
A straight trough 7 along drillstock 2 diametrically.
Two gains 6 and two straight troughs 7 are all provided with and are set to along drillstock 2 diametrically, 2 stress balance of drillstock is made, guarantee electricity
Hammer, which is stablized, drives drillstock 2 to rotate.
In the present embodiment, the gain 6 is semicircle groove body, and the straight trough 7 is trapezoidal groove body.
Semicircle groove body is set by gain 6, straight trough 7 is set as trapezoidal groove body, to match with electric hammer mounting hole and collet
It closes.
Embodiment of above is only that preferred embodiments of the present invention are described, not to the utility model
Range be defined, under the premise of not departing from the spirit of the design of the utility model, this field ordinary engineering and technical personnel to this
The various changes and improvements that the technical solution of utility model is made should all fall into the guarantor that claims of the utility model determine
It protects in range.
