Abstract
The utility model discloses a linear driving structure, which comprises a beam, a linear guide rail pair arranged on the beam, a stand column arranged on the linear guide rail pair, and a linear motor arranged between the beam and the stand column; the cross beam is provided with two stepped rail mounting planes, and the linear guide rail pair is arranged on the two rail mounting planes. The utility model discloses can improve rigidity and precision, reduce volume, reduce mass, reduce cost to equipment.
Description
Technical Field
The utility model belongs to the drive structure of lathe, concretely relates to linear drive structure.
Background
Along with the rapid development of modern science and technology, the mechanical manufacturing industry starts to be comprehensively upgraded, and the development of high automation and precision technology is directed to enterprises, so that the innovation of the enterprises is required, the production efficiency is accelerated, the product quality is improved, and the precision, automation and intellectualization become the development direction of high-tech enterprises. Automatic change equipment often need adopt linear drive device, prior art includes linear electric motor drive device, the device middle and secondary two guide rails of linear guide arrange at the coplanar, linear electric motor installation face parallel guide rail mounting plane, this kind of guide rail is arranged, the rigidity is not enough under heavy cutting force effect, easy deformation, the precision is difficult to keep, and linear electric motor is flatly installing than installing occupation space to one side greatly, the slip table needs to be widened, the slip table quality has been increaseed, the thrust that provides under the condition of same acceleration increases, linear electric motor power has been increaseed to a certain extent, equipment cost has been increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can improve rigidity and precision, reduce cost's linear drive structure.
Realize the utility model discloses the technical scheme of purpose is:
the utility model provides a linear driving structure, which comprises a beam, a linear guide rail pair arranged on the beam, a stand column arranged on the linear guide rail pair, and a linear motor arranged between the beam and the stand column; the cross beam is provided with two stepped rail mounting planes, and the linear guide rail pair is arranged on the two rail mounting planes.
The linear motor is arranged between the two rail mounting planes.
The linear motor is obliquely arranged between the two rail mounting planes.
The linear guide rail pair is fixed on the cross beam through a linear guide rail pressing block, the linear motor comprises a secondary part fixed on the cross beam and a primary part fixed on the stand column, the left side and the right side of the stand column are respectively provided with a right collision block and a left collision block, and the stand column is provided with a linear grating measuring head through a measuring head mounting seat.
Has the advantages that:
the utility model discloses compare with current linear electric motor drive structure, the advantage lies in that two linear electric motor are vice stagger to be arranged on two parallel planes, and linear electric motor installation face becomes certain contained angle with the vice installation face of guide rail, and accurate position feedback is realized to the linear grating in whole stroke range. The two linear guide rail pairs are arranged in a staggered mode, the whole mechanical property is good, the rigidity is strong, and particularly the cutting force in the Y-axis direction is more obvious. The linear electric motor is obliquely arranged, the whole structure is compact, and the weight of the upright post is reduced from two aspects: 1) an inclined plane is designed below the upright post, so that the weight of the upright post is reduced; 2) the linear motor is obliquely arranged, so that the width of the upright post in the Y direction can be effectively reduced, and the weight of the upright post is reduced; under the condition of the same acceleration, the smaller the mass is, the smaller the force is required, so that the power of the linear motor can be effectively and reasonably selected, and the cost of the whole equipment is reduced. The high-thrust linear motor is directly driven, the dynamic response performance is good, high-speed and high-acceleration operation can be realized, the linear motor is obliquely arranged, the structure is compact, the occupied space is small, and the overall cost is reduced. The linear grating realizes accurate position feedback in the whole travel range and realizes high-precision operation.
The technical scheme of the utility model is further explained in the following with the attached drawings.
