Detailed Description
The following detailed description of the utility model refers to the accompanying drawings and preferred embodiments.
As shown in fig. 1, the lifting unit of the exchange workbench comprises a lifting bracket 1, wherein the lifting bracket is used for bearing an upper workbench and a lower workbench; the lifting guide device 2 is used for guiding the workbench when lifting and preventing the bracket from shaking when the workbench is lifted; the hydraulic device 3 is a driving device for lifting and lowering the exchange workbench; the fixed base 4 is fixed on the ground and plays a supporting role. The device is mainly an improvement on the lifting guide device, and is specifically as follows: as shown in fig. 2 and 3, the elevation guide 2 includes a tripod 21, a two-degree-of-freedom roller 22, and a roller rail 23. Two rollers 22 with two degrees of freedom are vertically arranged on the tripod 21 (the roller base is welded on the tripod, the rollers are rotatable), and the tripod 21 and the lifting bracket 1 are connected into a whole through 4 bolts. In addition, a dust guard 24 is mounted on the tripod 21 to prevent dust from entering the guide rail to cause lifting and clamping.
The guide rail 23 is welded on the fixed base 4, and when the workbench is lifted, the roller 22 slides in the guide rail 23 to limit the displacement of the lifting bracket 1 in the horizontal direction, so the workbench cannot shake back and forth and left and right, and the lifting is stable.
As shown in fig. 4, the dual-degree-of-freedom roller 22 is a conventional structure, also called a composite roller bearing, and the dual-degree-of-freedom roller 22 includes a lubrication nozzle 221, a large roller 222, a small roller 223, and a roller base 224. The roller base 224 is welded to the tripod 21, and a grease nipple 221 for supplying grease to the large and small rollers is mounted on the roller base 224.
As shown in fig. 5, each hydraulic lifting unit comprises a left group of guiding devices and a right group of guiding devices, 2 rollers 22 with two degrees of freedom are vertically arranged in each group, the large rollers 222 can limit the displacement of the lifting bracket in the Y direction, and the small rollers can limit the displacement of the lifting bracket 1 in the X direction, so that the lifting process of the workbench is ensured not to shake.
When the workbench is lifted, the rollers with double degrees of freedom slide in the guide rail grooves to limit the displacement of the lifting bracket in the X and Y directions, so that the lifting process of the workbench is free from shaking, the workbench is more stable, the damage to the hydraulic power mechanism is reduced, and the service life is prolonged.
It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be comprehended within the scope of the present utility model.
