Portal type machining center stable in clamping

Abstract

The invention relates to the field of machining center equipment, and discloses a portal type machining center stable in clamping. The portal type machining center stable in clamping is characterizedin that two stable seats symmetrical to each other are arranged on a workbench in the vertical movement direction, the steady seat is erected among a plurality of adjacent bench seams, the steady seatcomprises a plurality of I-shaped blocks adaptive to the bench seams, flange plates and a web plate of each I-shaped block surround one another to form a containing cavity for containing the edge ofthe corresponding bench seam, a plurality of bolt holes used for connection are formed in each of the two opposite flange plates on each I-shaped block, all the adjacent I-shaped blocks are connectedthrough a connection arm, a stable clamp is rotatably connected with the top end of the connection arm, the stable clamp comprises a clamp cover, and clamp head assemblies symmetrical to each other and used for clamping a workpiece are connected onto the clamp cover in a sliding mode. The portal type machining center stable in clamping alleviates the deformation problem of a bench surface during the long use process, prevents the waggling phenomenon caused by untight connection between the workpiece and the workbench from occurring in the moving process, and achieves high precision operation of a machining center.

Description

technical field [0001] The invention relates to the field of machining center equipment, in particular to a stably clamped gantry-type machining center. Background technique [0002] The gantry-type machining center refers to the machining center with the axis of the main shaft and the workbench set vertically. It is mainly suitable for processing large parts and can perform multiple processes such as milling, boring and drilling. The fixed gantry adjusts the plane, hole and other Complex surface is processed. During the processing, due to the difference in processing shape and precision, it is necessary to adjust the repeated displacement of the worktable in a short stroke. Although the large parts have high quality and strong displacement stability, slight shaking during repeated short-range displacement , is likely to become the main factor affecting the machining accuracy, and at the same time, the weight of large parts is suppressed in the middle of the workbench.

[0002] The gantry-type machining center refers to the machining center with the axis of the main shaft and the workbench set vertically. It is mainly suitable for processing large parts and can perform multiple processes such as milling, boring and drilling. The fixed gantry adjusts the plane, hole and other Complex surface is processed. During the processing, due to the difference in processing shape and precision, it is necessary to adjust the repeated displacement of the worktable in a short stroke. Although the large parts have high quality and strong displacement stability, slight shaking during repeated short-range displacement , is likely to become the main factor affecting the machining accuracy, and at the same time, the weight of large parts is suppressed in the middle of the workbench. During long-term continuous production operations, deformation will inevitably occur on the weak parts of the workbench under pressure, which will become an important factor affecting the machining accuracy. Therefore, it is necessary to Set up a stable fixture to increase the stability of the parts and the workbench, while avoiding the deformation of the workbench and ensuring the machining accuracy
