Embodiment Construction

[0025] The present invention will be further described below in combination with principle diagrams and specific operation examples.

[0026] In the preferred embodiment of the lift-type machine tool protective door of the present invention, it includes a protective door main body arranged on the machine tool protective cover. The connecting mechanism is fixedly connected with the main body of the protective door, and the driving mechanism is connected with the hydraulic control device. Under the control of the hydraulic control device, the driving mechanism drives the main body of the protective door to move. The sliding mechanisms are respectively located on both sides of the main body of the protective door and at the same time on the protective cover of the machine tool. superior.

[0027] Specifically, the connecting mechanism is a connecting bracket 5, and the piston rod of the hydraulic cylinder 3 is connected to the connecting bracket. see figure 1 As shown, the main...

Abstract

The invention discloses an elevating machine tool protection door, which comprises a protection door body, a driving mechanism and a connecting mechanism, wherein the protection door body is arranged on a machine tool shield; the machine tool shield is arranged out of a machine tool; the driving mechanism is fixedly connected with the protection door body by the connecting mechanism; the driving mechanism is connected with the hydraulic control device; and under the control of the hydraulic control device, the driving mechanism drives the protection door body to move. The elevating machine tool protection door has the reliable elevating action, and accurate stop can be realized on the opening and closing positions. When unforeseen circumstances happen, the door can be quickly locked, and the elevating action of oil cylinders on two sides of the door can be synchronous operated.

Description

technical field [0001] The invention relates to the technical field of a protective door and its control, in particular to a lift-type machine tool protective door for a large horizontal machining center machine tool and a hydraulic control device thereof. Background technique [0002] During the processing of workpieces in machining centers, a large amount of iron filings and coolant splashes are generated. In order to protect the personal safety of operators and maintain a good working environment around the machine tools, more and more fully enclosed protective covers are used on machine tools. The protective cover can effectively prevent safety accidents, protect personal safety and improve the working environment of machine tool operators. The workpiece is processed on the machining center machine tool equipped with the automatic workpiece exchange device. If it is necessary to pass through the fully enclosed protective cover of the machine tool, the protective cover mu...
