Description
Technical field
The utility model is related to motor field more particularly to a kind of axial motion mechanisms of grinding head motor.
Background technology
Grinding head motor is equally also suitable because its excellent performance is widely used in grinding, bores the fields such as milling at present
In the miniature aperture of high-speed grinding bearing and raceway groove etc..
The main shaft of traditional grinding head motor is usually axially moved by planker feed mechanism, and planker feed mechanism can be with shape
As ground is not understood as frame on guide rail, a slide unit can moving axially back and forth, due to, there are gap, therefore being be easy to cause in mechanism
The sudden and violent side of product, decorative pattern and finish and other issues.
Utility model content
Based on this, for above-mentioned technical problem, a kind of axial motion mechanism of grinding head motor is provided.
In order to solve the above technical problems, the utility model adopts the following technical solution：
A kind of axial motion mechanism of grinding head motor, including rotatable driving lever and by lever, the driving lever from
Rear side level penetrates motor case, and is fixed by clutch shaft bearing and the casing, described to be positioned horizontally in the casing by lever
Interior, its rear end is threadedly coupled with the driving lever, and the rear end connection of front end and electric machine main shaft, junction has second bearing.
This programme further includes cylinder and bearing block, the back-end closure of the cylinder, it is described advanced through by lever it is described
The rear end of cylinder, and its front end has the piston portion being adapted to the cylinder, the piston portion is connect with the cylinder, the axis
The rear end of bearing is connect with the cylinder, and closes the front end of the cylinder, and cushion chamber, institute are formed between the piston portion
Stating has buffer medium in cushion chamber, the second bearing is fixed in the bearing block.
The buffer medium is gas.
The driving lever is hollow tube, described to be stretched by the rear end of lever in the cavity of the driving lever, and the two screw thread
Connection.
The utility model realizes the axial feed motion of electric machine main shaft by the power that driving lever rotates, and power is by spiral shell
Line transmits, and improves the quality and precision of product processing, improves product qualification rate, avoids the sudden and violent side of product, decorative pattern and bright and clean
Degree and other issues.
Description of the drawings
The utility model is described in detail with reference to the accompanying drawings and detailed description：
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of axial motion mechanism of grinding head motor, including rotatable driving lever 110 and by lever
120。
Driving lever 110 penetrates motor case 2, and fix by clutch shaft bearing 130 and casing 2 from rear side level.
It is positioned horizontally in casing 2 by lever 120, its rear end is threadedly coupled with driving lever 110, front end and electric machine main shaft 3
Rear end connects, and junction has second bearing 140.
With forming screw thread pair by lever 120, driving lever 110 is rotated forward or is inverted driving lever 110, can make passive bar 120
Advance or retreat, so as to which electric machine main shaft 3 be driven to move axially, realize feeding.
In the present embodiment, driving lever 110 is hollow tube, is stretched by the rear end of lever 120 in the cavity of driving lever 110,
And the two is threadedly coupled.
The utility model is additionally provided with cylinder 150 and bearing block 160, the back-end closure of cylinder 150, by lever 120 forward
Across the rear end of cylinder 150, and its front end has the piston portion 121 being adapted to cylinder 150, and piston portion 121 is consolidated by axial
Rationed marketing is connect with cylinder 150, and the rear end of bearing block 160 is connect with cylinder 150, and the front end of closed cylinder 150, with piston portion
Cushion chamber A is formed between 121, there is buffer medium in cushion chamber A, second bearing 140 is fixed in bearing block 160.
When electric machine main shaft 3 is by external impact, cushion chamber A can play the role of buffering, so as to ensure feed accuracy.
Preferably, buffer medium is gas, it is of course also possible to be liquid or flexible solid material.
In the present embodiment, bearing block 160 is spliced to form by two parts.
The utility model realizes the axial feed motion of electric machine main shaft 3, and power by the power that driving lever 110 rotates
Transmitted by screw thread, improve product processing quality and precision, improve product qualification rate, avoid the sudden and violent side of product, decorative pattern and
Finish and other issues.
But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this
Utility model, and being not used as the restriction to the utility model, if in the spirit of the utility model, to
Variation, the modification of the upper embodiment will be all fallen in the Claims scope of the utility model.
