Description
Technical field
The present invention relates to linear motor field, in particular to a kind of linear motor with V-type arrangement.
Background technique
Ball screw or rack-and-pinion are carried as transmission frequently with rotating servo motor in traditional automation field
Mode, but the distinct disadvantages such as its transmission efficiency is low, structure is complicated, precision is not high, difficult in maintenance, noise is big make linear motor
Industrialization promotion is come into being.
Linear motor is divided into cored and iron-core less motor two major classes according to coil form, and iron-core less motor is due in coil
There is no iron cores from without magnetic attraction, but thrust is little, is used primarily in underloading field；Cored motor winds silicon in coil
Steel disc has been obviously improved thrust as iron core, is the optimal selection in heavily loaded High Speed Field.
However due to forming huge magnetic attraction between silicon steel sheet meeting and magnet, to overcome magnetic attraction bring deformation shadow
It rings, it is common practice that increase the thickness of mounting plate or (i.e. magnet is mounted on two coils by the installation of cored motor " mountain " type
Centre is parallel to each other between two coils).
But increases installation plate thickness and will increase mobile load quality；" mountain " type mounting structure is rigidly difficult to ensure.It is above-mentioned
Two kinds of solutions will increase the control difficulty of system so that accuracy decline.The present invention is to solve the prior art
Deficiency provides a kind of use structure of novel cored motor
Summary of the invention
For of the existing technology since the cored structure of the linear motion actuator weight of magnetic attraction bring is big, poor rigidity is asked
Topic, the purpose of the present invention is to provide a kind of linear motors with V-type arrangement.
To achieve the above object, the technical solution of the present invention is as follows:
A kind of linear motor with V-type arrangement, including pedestal, the cross section of the pedestal are in " recessed " shape, bottom
The medial surface of seat is V-shaped, and primary or secondary is equipped on the medial surface of pedestal V-arrangement, described primary including coil and iron core, institute
Stating secondary includes magnet；
Guide rail, the guide rail are mounted on the upper plane of pedestal, and guide rail is equipped with sliding block；
Workbench, the workbench are fixedly connected with the sliding block, and the cross section of workbench is in " T " shape, workbench
Two sides for protruding part are V-shaped, are equipped on two sides of the protrusion part of workbench secondary or primary；
The pedestal medial surface is equal with the workbench protrusion V-arrangement angle of side of part.
Further, the coil is mounted on the side wall of groove or the side wall of protrusion part by pinboard.
Preferably, the angle between the opposite two side walls of the groove is 8-12 °.
Preferably, the angle between the opposite two side walls of the groove is 10 °.
Further, grating scale is installed on the pedestal, encoder is installed on the workbench.
Preferably, the middle line of the grating scale short transverse and the middle line in rail height direction are contour.
Preferably, the middle line of the encoder short transverse and the middle line in rail height direction are contour, and encoder is mounted on
The medium position in working table movement direction.
Further, anticollison block and buffer are mounted on the pedestal.
Preferably, the pedestal and workbench are integrally formed manufacture.
Preferably, it is aligned in the middle part of the anticollison block and workbench.
By adopting the above technical scheme, due to for installing angle, protrusion between coil or the recess sidewall of magnet
Angle between point side wall exists, and the magnetic attraction between coil and magnet is cancelled out each other major part, in this way, then
Rigid " mountain " type mounting structure can be reduced by not needing the thickness for increasing mounting plate and use；It is effective to guarantee straight-line electric equipment
There is sufficiently strong rigidity, and the quality of linear motor does not have additional increase；Realize linear motor integral miniaturization and lightweight.
