Description

Technical Field

[0001] The utility model relates to the technical field of power heads of numerically controlled machine tools, in particular to a device for adjusting the power heads up and down. Background Art

[0002] The processing of parts on CNC machine tools mainly depends on the processing procedures. Unlike ordinary machine tools, it is not necessary to manufacture and replace many molds and fixtures, and it is not necessary to readjust the machine tools frequently. Therefore, CNC machine tools are suitable for occasions where the processed parts are frequently replaced, that is, they are suitable for the production of single pieces and small batches of products and the development of new products, thereby shortening the production preparation cycle and saving a lot of process equipment costs.

[0003] At present, the power heads of existing CNC machine tools are basically fixed directly by several bolts, and the height cannot be adjusted according to the workpiece being processed, which greatly limits the scope of use of the machine tool. Other methods need to be considered to enable the machine tool to process unsuitable workpieces, which is very inconvenient. Utility Model Content

[0004] The utility model aims to provide a power head up and down adjustment device to solve the above-mentioned problems.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The utility model discloses a device for adjusting a power head up and down, comprising a mounting seat, a movable seat and a fixed seat, wherein the fixed seat is connected to the mounting seat, the movable seat is W-shaped, a sliding hole for cooperating with the movable seat is provided on the mounting seat, the movable seat is slidably connected to the mounting seat, two symmetrically arranged fixed spindles are installed on the mounting seat, two symmetrically arranged moving spindles are installed on the moving seat, a lifting assembly is installed on the top of the fixed seat, the lifting assembly is connected to the moving spindle, a vertically arranged scale is connected to the top of the mounting seat, and a slot for inserting the scale is provided at the bottom of the moving seat.

[0007] Furthermore, the lifting assembly includes a cylinder installed on the fixed seat, a cross plate is installed on the top of the telescopic end of the cylinder, and pull rods are installed at both ends of the cross plate. The bottom of the pull rod passes through the through hole opened at the top of the fixed seat and is connected to the dynamic main shaft.

[0008] Furthermore, both the movable seat and the fixed seat are provided with strip-shaped holes, and the two strip-shaped holes are connected by bolts and nuts.

[0009] Compared with the prior art, the beneficial technical effects of the utility model are:

[0010] The utility model can use the lifting component to control the main shaft to rise or fall, which greatly improves the applicability of machine tool processing, and can use a scale to intuitively judge the lifting height, which is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS
