Abstract
The utility model discloses a kind of miniature electromotive handspikes, including shell, motor, shaft coupling, ball screw, ball screw, screw support body and cylinder rod.One end of shell is arranged in motor, is connected by shaft coupling with ball screw, and ball screw is mounted on ball screw and can slide axially along ball screw, and screw support body is connected with ball screw, and cylinder rod is fixed on screw support body；It further include the upper slide being fixed on above shell, and the decussation roller guide rail for being arranged between shell and upper slide and matching with upper slide, the end of the cylinder rod are additionally provided with push rod baffle.The utility model optimizes push rod internal structure, greatly reduces volume, facilitates installation and carries, in addition, it uses guidance system instead decussation roller guide rail, enables linear precision when linear slide to be less than 5um, while having the advantage of low vibration, high load-carrying when level crossing transmission again.
Description
Technical field
The utility model relates to a kind of miniature electromotive handspike, it is to become moving along a straight line by rotary motion, belongs to executing agency
Technical field.
Background technique
Known existing miniature electromotive handspike is mainly made of motor, pushing rod sleeve, screw rod, push rod, spindle nose and gear.It utilizes
Motor drives two gear drive operations, so that realize becomes moving along a straight line by rotary motion, the electric pushrod energy of this kind of structure
Consumption is big, volume is big, and use scope is restricted.In addition, existing linear type guidance system selects linear guide mostly, operation
Precision is low, and reliability is not high.
Utility model content
In order to overcome the problems referred above, the utility model provides a kind of miniature electromotive handspike, and which solve traditional electric pushrod bodies
The problem that product is big, precision is low.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of miniature electromotive handspike, including shell,
Motor, shaft coupling, ball screw, ball screw, screw support body and cylinder rod.Wherein, one end of shell is arranged in the motor,
It is connected by shaft coupling with ball screw, and ball screw is mounted on ball screw and can slide axially along ball screw,
Screw support body is connected with ball screw, and cylinder rod is fixed on screw support body.It further include the upper cunning being fixed on above shell
Plate, and the decussation roller guide rail for being arranged between shell and upper slide and matching with upper slide, the end of the cylinder rod is also
It is provided with push rod baffle.
Further, cylinder rod outer cover is equipped with sliding shaft sleeve.
Further, inner walls are additionally provided with pinboard, and are fixed on pinboard and with ball screw close to connection
The bearing seat that axis device one end matches.
Further, baffle is additionally provided between shell and upper slide.
The utility model compared with prior art, the advantage is that:
The utility model optimizes push rod internal structure, greatly reduces volume, facilitates installation and carries, in addition, will
Guidance system uses decussation roller guide rail instead, enables linear precision when linear slide to be less than 5um, while when level crossing transmission again
There is the advantage of low vibration, high load-carrying.In addition, roller screw rod transmission selects two kinds of precision of C7, C5, driven by micro-stepping system
It is dynamic, show higher positioning accuracy when with low speed microfeed.
Below with reference to drawings and examples, the utility model is described in detail.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model.
Fig. 2 is the main view of the utility model.
Fig. 3 is the A-A cross-sectional view of Fig. 2.
Fig. 4 is the B-B cross-sectional view of Fig. 2.
Specific embodiment
Embodiment,
Please refer to Fig. 1 to 4, a kind of miniature electromotive handspike, including shell 1, motor, shaft coupling 2, ball screw 3, ball wire
Mother 4, screw support body 5, cylinder rod 6, sliding shaft sleeve 7, upper slide 8 and baffle 9.
Wherein, one end of shell 1 is arranged in motor (not shown), is connected by shaft coupling 2 with ball screw 3
It connects, ball screw 4 is mounted on ball screw 3 and can slide axially along ball screw 3, screw support body 5 and ball screw 4
It is connected, cylinder rod 6 is fixed on screw support body 5.Sliding shaft sleeve 7 is set in outside cylinder rod 6.
Upper slide 8 is fixed on the top of shell 1, and one end between shell 1 and upper slide 8 is equipped with baffle 9.
The decussation roller guide rail 10 matched with upper slide 8, the cylinder rod 6 are additionally provided between shell 1 and upper slide 8
End be additionally provided with push rod baffle 11.
It is additionally provided with pinboard 12 in 1 inner wall of shell, and is fixed on pinboard 12 and with ball screw 3 close to shaft coupling
The bearing seat 13 that device one end matches.
The above is only the preferred embodiment to utility model, is not defined to the range of utility model, therefore
Under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to construction described in the utility model, spy
The equivalence changes or decoration that sign and principle are made, should all fall into the protection scope of the utility model.
