Embodiment Construction

[0017] The embodiment of the present invention mainly includes inner and outer guide seats (1, 3), sliding sleeve (2), servo electric cylinder (18) and anti-rotation device, and the inner and outer guide seats (1, 3) are inner and outer Set it up and secure it with screws at the bottom. The sliding sleeve (2) is located between the inner and outer guide seats (1, 3), and can slide up and down therebetween.

[0018] The cylinder body of the servo electric cylinder (18) is set in the inner guide seat (1), and is fixed on the inner guide seat (1) through the end plate (14); the sliding sleeve (2) and the servo electric cylinder (18) The cylinder rod (8) is connected, and can slide up and down under the promotion of the cylinder rod (8). A load cell (13) and an anti-rotation device are connected in series on the cylinder rod (8), and the rod end of the cylinder rod (8) is provided with a ball joint floating support assembly composed of a ball head (9) and a ball socket (10).

Abstract

The invention relates to a vertical supporting device driven through a servo electric cylinder. The vertical supporting device driven through the servo electric cylinder is mainly composed of an inner guiding base (1), an outer guiding base (3), a sliding sleeve (2), the servo electric cylinder (18) and an anti-rotation device, wherein the sliding sleeve (2) is arranged between the inner guiding base (1) and the outer guiding base (3), the cylinder body of the servo electric cylinder (18) is arranged in the inner guiding base (1), and the inner guiding base (1), the outer guiding base (3), the sliding sleeve (2) and the servo electric cylinder (18) are arranged in a stacked and overlapped mode; a cylinder rod (8) is further connected with a force measuring sensor (13) and the anti-rotation device in series, and the anti-rotation device is provided with travel dead stop iron (5), a travel adjusting nut (6), switch stop iron (17) and an approach switch (20); the rod end of the cylinder rod (8) is provided with a bulb (9) and a bulb socket base (10) capable of installing a machined workpiece. The vertical supporting device has the advantages that the axial size is small, supporting rigidity is good, and three protection of servo soft limiting, a travel switch and the mechanical stop iron can be achieved.

Description

technical field [0001] The invention relates to a machining fixture of a combined machine tool, in particular to a vertical support device driven by a servo electric cylinder. It is mainly used for auxiliary support when processing large workpieces. Background technique [0002] In the aviation industry manufacturing industry, for the manufacture and assembly of large parts, the attitude of the parts needs to be adjusted during the production process. At present, the commonly used posture adjustment method is to arrange three three-coordinate adjustment devices under the part. The vertical support device is usually designed as a servo motor, coupling, screw, and support column connected in series. The support column and wire The rod and nut are connected, the lead screw rotates, and the nut moves linearly, driving the support column to move. This support structure has disadvantages, such as large size in the vertical direction and poor rigidity, so it cannot be used in som...
