Protective type machine tool screw rod stroke stopper mechanism

Abstract

The invention provides a protective type machine tool screw rod stroke stopper mechanism which comprises a bearing base body, a nut seat, baffle plates, electric folding rods, an elastic cushion block, a drive guide rail, a pressure sensor, a tilt angle senor, a proximity sensor, a distance measuring sensor and a control circuit. The nut seat is embedded into the bearing base body; at least one drive guide rail is arranged on the side surface of the bearing base body; the at least two baffle plates are arranged and are symmetrically distributed on the front end surface and the back end surfaceof the bearing base body with respect to the axis of the bearing base body; and the back ends of the baffle plates are mutually connected onto the end surface of the bearing base body through the atleast two electric folding rods. According to the protective type machine tool screw rod stroke stopper mechanism provided by the invention, on one hand, the requirement on limiting and protecting a machine tool screw rod device can be effectively met, and the safety protection operation position can be flexibly adjusted according to the requirement of machine tool running operation; on the otherhand, the protection operation control accuracy is high, so that the control accuracy of the relative position relation between a stopper and machine tool equipment during protection operation can beeffectively improved; and meanwhile, the protective type machine tool screw rod stroke stopper mechanism has favorable bearing capacity and unloading capacity.

Description

technical field [0001] The invention relates to a protection type machine tool lead screw stroke stopper mechanism and belongs to the technical field of machine tool equipment. Background technique [0002] The screw is one of the important driving equipment in the machine tool equipment. Its running stability plays a vital role in the reliability and accuracy of the machine tool. Currently, in order to prevent the machine tool parts and workpieces connected to the screw Accidents such as excessive stroke and collision due to misoperation, and the overload of the lead screw caused by these accidents seriously affect the stability of the lead screw operation, and the machine directly leads to damage to the structure of the lead screw. Install the traditional elastic block on the bed at both ends of the lead screw device or simply add one or several in-position sensors and other devices on the basis of the elastic block.

[0002] The screw is one of the important driving equipment in the machine tool equipment. Its running stability plays a vital role in the reliability and accuracy of the machine tool. Currently, in order to prevent the machine tool parts and workpieces connected to the screw Accidents such as excessive stroke and collision due to misoperation, and the overload of the lead screw caused by these accidents seriously affect the stability of the lead screw operation, and the machine directly leads to damage to the structure of the lead screw. Install the traditional elastic block on the bed at both ends of the lead screw device or simply add one or several in-position sensors and other devices on the basis of the elastic block. Although it can basically meet the needs of use, it will On the one hand, there is poor detection accuracy, which leads to relatively poor protection efficiency, and cannot completely and effectively prevent the occurrence of excessive strokes of the machine tool. As a result, when a collision occurs, the structure of the machine tool equipment is seriously damaged due to poor unloading control accuracy. In addition, the current stroke stopper also has a fixed installation structure during installation and operation, and it cannot be flexibly randomized according to the use of the machine tool. The adjustment of the operating state of the equipment severely limits the flexibility and versatility of the travel stopper equipment, and it is very easy to cause the decrease of the protection ability due to the change of the relative positional relationship between the travel stopper and the moving parts of the machine tool.
