Description

linear motion mechanism

technical field

The utility model relates to a linear motion mechanism in the up and down direction, which enables the lifting frame to perform linear motion in the up and down direction under the drive of the driving mechanism.

Background technique

The equipment with lifting frame is often used in the factory. The movement of the lifting frame is a linear motion in the up and down direction, driven by the driving mechanism (including the oil cylinder structure, the cylinder structure, the screw structure, etc.). The installation structure of the lifting frame is that there is a base under the lifting frame, and a linear guide rail is installed between the base and the lifting frame. Since the linear guide rail is an outsourced precision component, it is mostly used in linear motion that requires high precision, such as machine tools, etc. . For the linear motion in the up and down direction of the ordinary lifting frame, if the linear guide rail is used, it will not only cause high equipment cost, but also cause complicated processing technology and troublesome installation and adjustment.

Contents of the invention

The purpose of the utility model is to provide a linear motion mechanism with simple processing technology, low cost, easy installation and suitable for common lifting frames.

The linear motion mechanism of the utility model comprises a base and a lifting frame connected to the base, a vertical slideway is fixedly connected to the base, and the section of the vertical slideway is groove-shaped; The bottom surface of the groove of the slideway matches, and the connecting plate is also equipped with guide wheels to match the groove side of the vertical slideway, and the connecting plate is fixedly connected with the described lifting frame.

In the linear motion mechanism of the present utility model, an adjusting backing plate is provided between the connecting plate and the traveling wheels.

The linear motion mechanism of the utility model has the advantages of simple overall structure, easy manufacture and installation, convenient adjustment and low cost.

Description of drawings

Fig. 1 is the structural representation of the specific embodiment of the present utility model;

Fig. 2 is a schematic left view of Fig. 1 .

Detailed ways

As shown in Figures 1 and 2: the lifting frame is composed of two beams 3, four vertical beams 4 and a platform 5 above to form a frame structure.

1 is a base, and the four corners on the base 1 are welded or bolted to be connected with a vertical slideway 2. The section of the vertical slideway 2 is groove-shaped, and a pair of vertical slideways at each end are symmetrically arranged and the notch is outward.

Every vertical slideway 2 is equipped with connecting plate 9, on the connecting plate 9, traveling wheel 10 is installed by support 11 and rotating shaft, and support 11 is fixedly connected with connecting plate 9 bolts, and the groove of traveling wheel 10 and vertical slideway 2 Bottom surface matches; Also guide wheel 7 is installed by wheel shaft on connecting plate 9, and the outer diameter of guide wheel 7 coincides with the two side surfaces of vertical slideway 2 groove inboards, promptly can slide up and down in it and plays guiding effect.

The connecting plate 9 is fixedly connected with the long drop frame by bolts, so that the drop frame can move up and down along the four slideways 2.

An adjustment backing plate 8 is provided between the connecting plate 9 and the bracket 11 , and the sliding gap in the up and down direction can be adjusted by changing the thickness of the adjustment backing plate 8 .

When working, the lifting frame can move linearly in the up and down direction relative to the base 1 under the drive of the driving mechanism (including the oil cylinder structure, the cylinder structure, the screw structure, etc.). Low.
