By utilizing the structure provided by the invention, a continuous hammering function is realized in a compact space, and the energy utilization efficiency is improved; continuous efficient striking on a nail can be achieved, thereby effectively avoiding the trouble that the nail cannot be nailed by a single-shot nailing gun under certain working conditions; and moreover, as the nail is stricken by the air hammer, the striking force is great.
Description
Technical field
The present invention relates to the electric tool technical field, particularly a kind of ailing machine.
Background technology
Ailing machine is a kind of hand-held tool commonly used, and it is of a great variety.According to power source, ailing machine can be divided into pneumatic and electronic two big classes.Wherein, gas pin gun must have compressed air source, therefore uses limited.The basic structure present situation of Electric Tacker:
A kind of is as rotation-rectilinear motion transmission mechanism and with the ailing machine of battery as power supply with slider-crank mechanism.The problem one that this type of ailing machine exists is that slider-crank mechanism can not be realized impacting truly coming down to a kind of " pushing away " nailing machine structure, and the operating efficiency of therefore each nailing is not high; The 2nd, motor is placed in handle the place ahead or rear side, is connected with transmission mechanism to occupy than large space, makes that the ailing machine volume is bigger, and it is all convenient inadequately to carry and manipulate.
Another kind is by pinion and rack the motor rotation to be converted to the active force that compresses spring earlier, relends to help tripping mechanism to discharge the compression spring, thereby produces the ailing machine of impulsive force.Though this ailing machine utilizes spring energy-storage, realized the moment of nail is impacted, can only click one by one, can't impact continuously, the therefore long-term operating efficiency of using is still not high; In addition, its motor is in the casing of rifle head below, separates fully with handle, still has the not compact problem of structure.
Also have a kind of spring energy-storage and impact block inertia nail hitting structure utilized, though the compact and continuous nail hitting of structure, nail hitting strength is little, can not effectively impact the nail of various models, only is fit to smaller nail; And the easy fatigue failure of the spring in this structure, service life is short, hits lack of homogeneity, and energy conversion efficiency is low, and the battery power consumption is fast, and single battery bag nailing quantity is few.
Summary of the invention
The purpose of this invention is to provide a kind of have impact usefulness continuously and impulsive force is big, the high efficiency of nailing, compact conformation, volume is little, carries and manipulate the ailing machine of all convenient and long service life.
The present invention is achieved through the following technical solutions:
A kind of ailing machine, comprise the casing cavity, motor, the casing cavity is involuted by left and right sides two halves casing, it is characterized in that: the main part of described casing cavity forms vertical handle, the upper end of the main part of casing cavity is protruded forward and is formed horizontal rifle mouth, upper end in the main part of casing cavity is equipped with cylinder block, on cylinder block, be provided with air admission hole and steam vent, be provided with rotation-rectilinear motion switching transmitting mechanism at the casing cavity, motor is connected with piston by rotation-rectilinear motion switching transmitting mechanism, in the rifle mouth, be provided with the nail hitting pin of top nail, the nail hitting pin is horizontally disposed with, be fixed in the cylinder block by positioning sleeve, piston is installed in cylinder block, in piston, be provided with the axial cavity that an end is provided with opening, in the axial cavity of piston, pneumatic hammer is installed by rubber seal, the axis of nail hitting pin, the axis of cylinder block, the axis three of pneumatic hammer is coaxially set, on the rifle mouth, also be provided with an appearance nail mouth that forms by the indentation structure, hold the axis of nail mouth and the axis coaxle line of nail hitting pin and be provided with.
Described motor vertically is installed in the main part of casing cavity, rotation-rectilinear motion switching transmitting mechanism comprises a pair of bevel gear, Oscillating lever bearing, jackshaft and the bevel gear shaft of finishing deceleration and indexing, Oscillating lever bearing and jackshaft close-fitting, Oscillating lever bearing is connected with piston hinge, jackshaft is vertical mutually with bevel gear shaft, and a bevel gear is installed on the jackshaft, and bevel gear shaft is installed another bevel gear, bevel gear shaft is provided with flexible connection structure, is flexible coupling to be connected with the output shaft of motor.
The top of described pneumatic hammer and piston is provided with and promotes pneumatic hammer axially and the air spring of nail hitting pin contacts
Described motor is by power brick or AC-powered.
Described steam vent is provided with two.
The present invention compared with prior art has the following advantages:
1) when the rotation of motor was converted to the fork reciprocating motion of Oscillating lever bearing by transmission mechanism after, piston drove pneumatic hammer and moves back and forth, and rotate to the conversion of pneumatic hammer rectilinear motion thereby finished by motor, thereby pneumatic hammer directly impacts the nail hitting pin.Because the weight of pneumatic hammer and have certain speed when impacting the nail hitting pin, thereby can produce than advancing and impact effect more efficiently, and Oscillating lever bearing just can be realized impacting continuously when continuing continuous the biography.
2) impact usefulness in order to improve, therefore at pneumatic hammer and top land air spring is arranged, and cylinder has two steam vents, when reciprocating motion of the pistons is with respect to the cylinder primary importance like this, the nail hitting pin is because negative pressure moves to the top, pneumatic hammer runs to piston base, and this moment, air spring was in energy accumulating state; When piston moved to respect to the cylinder second place, the nail hitting pin released energy because malleation compresses nail, and pneumatic hammer directly impacts the nail hitting pin, and the air spring compression guarantees that motor normally rotates, and the timely exhaust of inblock cylinder pore guarantees that the pneumatic hammer nail hitting is strong.
In a word, the ailing machine of structure of the present invention is owing to rationally be provided with motor and driving mechanism, by innovation to traditional cylinder electric hammer structure, adopt " semiaxis " transmission, continuous hammering function in tight space, and improve the Energy Efficient rate, finally make this structure in charging mean and narrow working space hammer nail function.The present invention can realize the continuous high-efficient of a nail is hit, and has effectively avoided using under some working environment the disposable trouble that the type ailing machine can't hammer into nail of injecting.The present invention has realized operating grip and has hammered into direction and become an angle of 90 degrees degree, has effectively avoided can't hammering at narrow space the trouble of nail.The present invention adopts the pneumatic hammer nail hitting, and it is big to impact strength, finishes the task that general nail rifle can't be finished.
Description of drawings
Fig. 1 is the schematic perspective view that the present invention preferably implements;
