Abstract
The utility model provides a motor-driven lifting platform which is low in relative initial height and stable in lifting. The lifting platform comprises a lifting platform base plate, a screw, a back baffle and a bottom wedge-shaped block. The screw, the back baffle and the bottom wedge-shaped block are located on the lifting platform base plate. A top wedge-shaped block is arranged above the bottom wedge-shaped block, and the contact face of the bottom wedge-shaped block and the top wedge-shaped block is inclined face. A driving nut is arranged on the bottom wedge-shaped block and is installed on the screw, and the screw is connected with the driving motor. A lifting platform face is arranged above the top wedge-shaped block, and intersected ball guide rails are arranged between the lifting platform base plate and the bottom wedge-shaped block and between the bottom wedge-shaped block and the top wedge-shaped block. The motor-driven lifting platform is compact in structure, high in load, low in relative initial height, linear in lifting coefficient and high in location accuracy.
Description
Technical field
The utility model relates to a kind of bay-lift, especially a kind of electric up-down platform.
Background technology
There is bigger position error in the process that existing scissor bay-lift uses in operation, and the precision of measurement is low, poor repeatability, and staring torque is big, and the lifting coefficient is problem such as non-linear.The guide colume type bay-lift then exists volume bigger, and the elemental height height repeats problems such as qualitative difference.
The utility model content
The utility model provides that a kind of relative elemental height is low, lifting pulsation-free electric up-down platform.
Realize a kind of electric up-down platform of the utility model purpose, comprise the bay-lift base plate, be positioned at leading screw, back shield and bottom wedge on the described bay-lift base plate, the top of described bottom wedge is provided with the top wedge, and the contact surface of described bottom wedge and top wedge all is the inclined-plane; Described bottom wedge is provided with drive nut, and described drive nut is installed on the leading screw, and described leading screw is connected with drive motor; The top of described top wedge is provided with the bay-lift table top; Be provided with between described bay-lift base plate and the bottom wedge and between bottom wedge and the top wedge and intersect spherical guide.
Be provided with deep groove ball bearing between described top wedge and the back shield, be provided with drag spring between described deep groove ball bearing and the top wedge.
Be provided with guard shield between described bay-lift table top below and the back shield.
Be provided with bearing between described leading screw and the bay-lift base plate.
The beneficial effect of a kind of electric up-down platform of the present utility model is as follows:
A kind of electric up-down platform of the present utility model, compact conformation, high-mechanic, elemental height is low relatively, and the lifting coefficient be linearity, the accuracy of positioning height.
Description of drawings
Fig. 1 is the structural representation of a kind of electric up-down platform of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of electric up-down platform of the present utility model, comprise bay-lift base plate 1, be positioned at leading screw 10, back shield 3 and bottom wedge 2 on the described bay-lift base plate 1, the top of described bottom wedge 2 is provided with top wedge 7, and described bottom wedge 2 all is the inclined-plane with the contact surface of top wedge 7; Described bottom wedge 2 is provided with drive nut 9, and described drive nut 9 is installed on the leading screw 10, and described leading screw 10 is connected with drive motor 12; The top of described top wedge 7 is provided with bay-lift table top 8; Be provided with between described bay-lift base plate 1 and the bottom wedge 2 and between bottom wedge 2 and the top wedge 7 and intersect spherical guide 13.
Be provided with deep groove ball bearing 4 between described top wedge 7 and the back shield 3, be provided with drag spring 6 between described deep groove ball bearing 4 and the top wedge 7.
Be provided with guard shield 8 between described bay-lift table top 8 belows and the back shield 3.
Be provided with bearing 11 between described leading screw 10 and the bay-lift base plate 1.
The principle of work of a kind of electric up-down platform of the present utility model is as follows:
Have special angle between bottom wedge 2 and the top wedge 7, can make wedge 2 edges in bottom away from the every mobile 2mm of drive motor 12 directions, top wedge 7 will be along back shield 3 1mm that moves up.Such lifting namely is linear 1: 2 relation than not changing along with the increase of the amount of movement of horizontal direction.
This promoting and demoting mechanism also produces the effect of reductor, when producing fixedly the lifting ratio, amplification is raised moment, makes that the load-carrying of bay-lift of this structure is bigger.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineering staff in this area make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
