Embodiment 1

[0024] Such as figure 1 As shown, the precise lifting and positioning device includes a base 1 and a top plate 2 arranged in parallel, a guide rod 3 and a screw 4 are arranged vertically between the top plate and the base, and a scale 5 is provided on the guide rod. A power output device 6 is installed, and the output end of the power output device is connected to the bottom end of the screw; a lifting mechanism 7 is installed on the screw rod, and a workpiece holder 8 is arranged on the lifting mechanism.

[0025] The side of the lifting mechanism is provided with a screw hole 9 and a bolt 10 passing through the screw hole, and the end of the bolt passing through the screw hole is in contact with the guide rod. When the lifting mechanism runs to the preset height and stops, the bolt is rotated to make it tightly contact with the guide rod, so that the lifting mechanism is fastened on the guide rod.

[0026] In this embodiment, the number of the guide rods is two, and they ar...

Abstract

The invention discloses an accurate lifting positioning device which comprises a base (1) and a top plate (2) which are arranged in parallel. A guide rod (3) and a screw (4) are arranged between the top plate and the base along the vertical direction. The guide rod is provided with scales (5). A power output device (6) is arranged in the base and an output end of the power output device is connected with the bottom end of the screw. The screw is provided with a lifting mechanism (7). The lifting mechanism is provided with a workpiece clamp holder (8). The device has a simple structure. Moreover, a machined workpiece can be accurately subjected to positioning of different heights.

Description

technical field [0001] The invention relates to the field of mechanical equipment manufacturing, in particular to a precise lifting and positioning device. Background technique [0002] During the production and processing of petroleum equipment, it is often necessary to raise or lower the processed workpiece to a specified height, and then perform the processing operation of the workpiece at this height level. The existing devices either have a complex structure and high cost; or cannot accurately position the height, and need an auxiliary scale or other height measuring instruments to measure the height of the workpiece. Therefore, there is a need for a device with simple structure, low cost, and accurate lifting and positioning. Contents of the invention [0003] The object of the present invention is to provide an accurate lifting positioning device, which has a simple structure and can precisely position the workpiece at different heights. [0004] The purpose of t...
