Abstract
The invention provides an interchange structure for different motors on the same casing. The interchange structure comprises a tool casing; a transmission mechanism component, a middle cover and an old motor are all arranged in the tool casing; the old motor is fixed on the middle cover; a transmission shaft of the old motor passes through the middle cover and is connected with the transmission mechanism component; an air inlet and an air outlet are formed in the tool casing; the external diameter of a new motor is smaller than the external diameter of the old motor; when the old motor is replaced with the new motor, the old motor is dismounted, and the new motor is fixed on the middle cover; a fan cover is arranged on the outer side of the new motor, and the external diameter is the same as that of the old motor; a combined type blade is arranged at one end, close to the air inlet, of the new motor. The invention realizes the interchange of different motors on the same casing by changing the external diameter of the motor and optimizing the flow direction of a wind path, and can realize rapid productization of an electric tool employing the new motor, thereby shortening the new product development period and saving the project investment cost.
Description
Technical field
The present invention relates to the mounting structure of motor in casing in electric tool, particularly relate to the mounting structure of different motor in identical casing.
Background technology
Electric tool, primarily of compositions such as running part, coupling part, motor, casing, wire, switches.The motor of use mostly before is series excited machine or steel pipe motor, and along with the raising of motor technology and technique, increasing product brings into use overall standard electromotor even brushless electric machine.
Traditional electric tool product, what mostly adopt is that a kind of outward appearance casing is arranged in pairs or groups a kind of form of model motor.Because the size of different style motor is different with wind path, therefore different motors cannot be general on a casing, needs for New-type electric machine configures the new casing adapted with it, and this adds the cost that new product is released undoubtedly, also extends the construction cycle simultaneously.
Based on the trend that New-type electric machine power increases from now on, build reduces, be necessary on the basis taking into full account the characteristic that multiple motor is different and wind path, research and develop a kind of structure that different motor can be exchanged on same casing.
Summary of the invention
The technical problem to be solved in the present invention is to provide the interchange structure of a kind of different motor on same casing, makes when only motor is different, reduces the cost that new product is released, and shortens the construction cycle.
In order to solve the problems of the technologies described above, technical scheme of the present invention is to provide the interchange structure of a kind of different motor on same casing, the mounting structure of old money motor on casing comprises instrument casing, transmission mechanism component, middle cover and old money motor are all located in instrument casing, the both sides of middle cover are located at respectively by transmission mechanism component and old money motor, old money motor is fixed in middle cover, and the power transmission shaft of old money motor is connected with transmission mechanism component through middle cover; Side near old money motor on instrument casing is provided with air inlet, and on instrument casing, the fan blade place of corresponding old money motor is provided with air outlet;
The external diameter of New-type electric machine is less than the external diameter of old money motor;
It is characterized in that:
When needs are replaced by New-type electric machine described old money motor, remove described old money motor, be fixed in middle cover by New-type electric machine by the position that described old money motor is original, the power transmission shaft of New-type electric machine is also connected with described transmission mechanism component through described middle cover;
Be provided with fan housing outside New-type electric machine, the external diameter of fan housing is identical with the external diameter of described old money motor;
New-type electric machine is provided with combined type fan blade near one end of described air inlet.
Preferably, described old money motor is fixed in described middle cover by trip bolt; When described old money motor is replaced by described New-type electric machine, described New-type electric machine is also fixed on described middle cover by described trip bolt by the position that described old money motor is original.
Structure provided by the invention overcomes the deficiencies in the prior art, by the wind path optimization of different motor at casing internal, to change the method for electric machine assembly outer dia and the optimization wind path flow direction, realize the exchange of different motor on same casing, can will use the rapid commercialization of electric tool of New-type electric machine, shorten new product development cycle, and save project investment cost.
Accompanying drawing explanation
Fig. 1 is the mounting structure schematic diagram of old money motor on casing;
The interchange structure schematic diagram of different motors on same casing that Fig. 2 provides for the present embodiment.
Embodiment
For making the present invention become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Fig. 1 is the mounting structure schematic diagram of old money motor on casing, the mounting structure of old money motor on casing comprises instrument casing 1, transmission mechanism component 2, middle cover 3 and old money motor 4, transmission mechanism component 2, middle cover 3 and old money motor 4 are all positioned at instrument casing 1, and transmission mechanism component 2 and old money motor 4 lay respectively at the both sides of middle cover 3.
Middle cover 3 and instrument casing 1 compact siro spinning technology, old money motor 4 is fixed in middle cover 3 by trip bolt 9; Old money motor 4 also has power transmission shaft 4-1 and fan blade 4-2, and power transmission shaft 4-1 is connected with transmission mechanism component 2 through middle cover 3, and motor 4 drives transmission mechanism component 2 to carry out work by power transmission shaft 4-1.Side near old money motor 4 on instrument casing 1 is provided with air inlet 6, and on instrument casing 1, corresponding fan blade 4-2 place is provided with air outlet 5.
Composition graphs 2, when old money motor 4 is changed to New-type electric machine 7 by needs, trip bolt 9 position dimension and the old money motor 4 of New-type electric machine 7 are consistent, and make installation site to produce variation.
Due to the raising of technical merit, the size of New-type electric machine 7 is general all little than old money motor 4, so increase fan housing 8 outside New-type electric machine 7, ensure that the external diameter of New-type electric machine 7 external diameter and old money motor 4 is consistent, and make wind path can cool the outside of New-type electric machine 7.
In addition, New-type electric machine 7 generally can not carry fan blade, so increase combined type fan blade 7-2 at New-type electric machine 7 afterbody, combined type fan blade 7-2 is positioned at one end of the air inlet 6 on instrument casing 1, ensure that the wind path trend of New-type electric machine 7 and the wind path of old money motor 4 move towards to be consistent, make the air inlet 6 of instrument casing 1 and air outlet 5 position can be general.
When changing motor, first instrument casing 1 being opened, old money motor 4 is separated with middle cover 3.Then New-type electric machine 7 is fixed in middle cover 3 by original position by trip bolt 9, the power transmission shaft 7-1 of New-type electric machine 7 is connected with transmission mechanism component 2 through middle cover 3, be fixed on outside New-type electric machine 7 by fan housing 8 again, finally close instrument casing 1, can use.
