Abstract
Disclosed in the utility model is a micro linear execution system. Especially, the micro linear execution system comprises a driving block, a stepping motor, a square nut, a motor fixed plate and at least one guide post. The driving block is provided with a guide post hole, a drive slot and a motor shaft channel; and one end of the guide post passes through the guide post hole in a slip joint way and the other end of the guide post is connected and fixed with the motor fixed plate. The stepping motor is fixed and connected with the motor fixed plate and a motor shaft of the stepping motor is a screw rod; and the motor shaft is inserted into the motor shaft channel. The square nut and the motor shaft are in a screw joint and the square nut is placed inside the drive slot and is limited. When the micro linear execution system provided by the utility model is applied, the employed novel system has advantages of simple structure, small size, low cost and simple assembling. Moreover, the driving block of the system can utilize the rotation of the motor shaft to make linear motions; the conventional stepping motor can be installed, thereby substantially reducing the cost.
Description
Technical field
The utility model relates to a kind of executive system, relates in particular to a kind of micro linear executive system.
Background technology
Linear executive system can be used for driver part and move by linear mode, and can come the particular location of motion is positioned by mechanical position limitation or position transducer, is the device that often uses in the industrial automation.
The straight linear executive system of prior art comprises straight linear actuator and linear electric motors, the straight linear actuator adopts slide rail and slide block combination restriction motor to do rectilinear motion along the slide rail direction, the slide rail that actuator adopts and slide block assembly are comparatively huge, take up room extremely many, and mechanism is more loaded down with trivial details, be not easy to install, actuator only plays single slide rail direction restriction to motor, must be equipped with special linear electric motors so be equipped with motor, special linear electric motors price is high, required cost is high, is unfavorable for social development.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the purpose of this utility model is to propose a kind of micro linear executive system, solves the linear executive system volume of prior art cathetus greatly and the high problem of institute's outfit linear electric motors price.
Above-mentioned purpose of the present utility model, the technical solution of its realization is: a kind of micro linear executive system, it is characterized in that: described micro linear executive system comprises drive block, stepping motor, square nut, motor fixing plate and at least one lead, and described drive block is provided with lead hole, driver slot and motor shaft passage; Described lead one end cunning wears and is connected in the lead hole, and the lead other end and motor fixing plate are connected and fixed; Described stepping motor and motor fixing plate are connected and fixed, and the motor shaft of stepping motor is screw rod, and described motor shaft is inserted in the motor shaft passage; Described square nut is bolted on the motor shaft, and square nut places in the driver slot also spacing.
Further, described micro linear executive system has two leads, and two leads are divided into the both sides of motor shaft, and the drive block correspondence is provided with two lead holes.
Further, the relative motor shaft Central Symmetry of described two leads.
Use a kind of micro linear executive system of the utility model, comparing existing straight linear executive system has advantages of: the micro linear executive system that has adopted innovation, this system simple in structure, small volume, cost is low, equips simple and easyly, and this system drive piece can utilize motor shaft rotation to move linearly, can be equipped with conventional stepping motor, greatly reduce cost.
Description of drawings
Fig. 1 is the structural representation of the utility model micro linear executive system preferred embodiment.
Fig. 2 be embodiment illustrated in fig. 1 in structural representation except stepping motor.
Fig. 3 is the structural representation of middle stepping motor embodiment illustrated in fig. 1 and square nut.
Embodiment
The utility model is the large and high phenomenon of institute's outfit linear electric motors price for the linear executive system volume of prior art cathetus, innovation has proposed a kind of micro linear executive system, this system bulk is small and rotarily drive the drive block moving linearly by motor shaft, has solved the large and high problem of institute's outfit linear electric motors price of the linear executive system volume of prior art cathetus.
As shown in Figure 1 to Figure 3, a kind of micro linear executive system, especially, this micro linear executive system comprises drive block 1, stepping motor 2, square nut 3, motor fixing plate 4 and at least one lead 5, and drive block is provided with lead hole 11, driver slot 12 and motor shaft passage 13; Lead one end cunning wears and is connected in the lead hole, and lead is mainly used in limiting the drive block displacement rails, and the lead other end and motor fixing plate are connected and fixed; Stepping motor and motor fixing plate are connected and fixed, motor is provided with the fixing hole (accompanying drawing omission mark) that is the diagonal angle, this fixing hole by with motor fixing plate on corresponding aperture be connected and fixed, the motor shaft 21 of stepping motor is screw rod, this motor shaft is inserted in the motor shaft passage; Square nut is bolted on the motor shaft, and square nut places in the driver slot and spacing, and driver slot does not rotate by the restriction square nut, indirectly defines this system linearity motion simultaneously.In addition, the micro linear executive system has two leads, and two leads are divided into the both sides of motor shaft, and the drive block correspondence is provided with two lead holes, has guaranteed this Systems balanth operation.The relative motor shaft Central Symmetry of above-mentioned two leads guarantees that further the linear track of this micro linear executive system motion is stable.
In addition, aforementioned conventional stepping motor can be reaction equation, magneto in the technical solutions of the utility model, hybrid or single-phase type is all applicable.As long as can relatively accurately control by step angle the anglec of rotation of motor.Select the external diameter size of stepping motor according to the demand of miniature applications, one of preferred is the magneto micro-step motor of external diameter 15mm.
During implementation, operate this micro linear executive system, stepping motor participation work, because driver slot restriction square nut does not rotate, so screw rod rotation by motor, so that square nut generation linear displacement, square nut generation linear displacement drives drive block and moves linearly along lead.
Can find out by above-mentioned character express, use a kind of micro linear executive system of the utility model, comparing existing straight linear executive system has advantages of: the micro linear executive system that has adopted innovation, this system simple in structure, small volume, cost is low, assemble simple and easy, and this system drive piece can utilize the motor shaft rotation to move linearly, and can be equipped with conventional stepping motor, greatly reduces cost.
In addition to the implementation, the utility model can also have other execution mode, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
