Description

Inverted telescopic armor protection

technical field

The invention relates to an inverted telescopic armor protection for machine tools.

Background technique

Armor protection is an important functional part of various metal cutting machine tools, increasing and decreasing compound machine tools, etc. The stretchability and acceleration of the protection rarely reach 1G, which has a great impact on the performance of the machine tool. In addition, the sealing during movement and the prevention of scorching hot iron filings splashing out during processing are important factors affecting the safety performance of the equipment. There are few types of existing inverted protection, the structure is complex, and the acceleration cannot keep up, which affects the processing speed and quality. For example, the fixed armor skin cavity protection, its structure is made of elastic skin cavity, each folded page is equipped with an armor piece, this structure can only be used in the vertical axis, later developed on the basis of this protection Fully protective armor leather cavity (FASTAC), each armor sheet covers the top and both sides of the leather cavity to form a closed protective surface. This type of protection is mostly used for fully enclosed protection of slides, and cannot be automatically opened and stretched. It can only be disassembled manually, and its running speed can only reach 30m/min or 0.5G acceleration. The previous armor protection structure is complex, the protection sealing performance is poor, and the acceleration inertia is large. Therefore, it is difficult to use it when there are more and more high-speed machine tools.

Contents of the invention

The technical problem solved by the invention is to overcome the deficiencies of the prior art and provide an inverted telescopic armor protection with quick response capability.

The technical scheme adopted in the present invention is an inverted telescopic armor protection. The fixed plate is installed on the beam of the movement axis of the machine tool, and the fixed plate is fixedly connected to the shrinkable iron absorber. One end of the inverted armor protection body is connected to the fixed plate, and the other end is connected to the front fixed support plate. A magnet suction plate is provided on the front fixed support plate corresponding to the contraction suction iron, the cylinder latch device is fixed on the machine column, and a latch block is welded and fixed at both ends of the front fixed support plate.

A protective baffle is fixedly installed on the front fixed support plate. A guide plate and a self-lubricating guide block are arranged below the inverted armor protective body.

The beneficial effect of the invention is that the inverted telescopic armor protection provides a fully enclosed space, prevents iron filings from splashing, is compact and sealed, and can increase the feeding space and other structures. It has the advantages of simple structure, easy assembly, small installation space, safe and reliable locking and good sealing effect.

detailed description

The present invention will be further described below in conjunction with accompanying drawing.

Inverted telescopic armor protection, the fixed plate 8 is installed on the beam of the machine tool movement axis, the fixed plate 8 is fixedly connected to the shrinkable iron absorber 7, one end of the inverted armor protection body 3 is connected to the fixed plate 8, and the other end is connected to the front fixed support plate 4. A magnet suction plate 4a is provided on the fixed support plate 4 at a position corresponding to the contraction suction iron 7, the cylinder latch device 1 is fixed on the machine column, and a latch block 4b is welded and fixed at both ends of the front fixed support plate 4.

The protective baffle plate 2 is fixedly installed on the front fixed support plate 4. A guide plate 5 and a self-lubricating guide block 6 are provided below the inverted armor protection body (3).

As shown in FIG. 1 , when the machine tool is in the processing state, the shrinkage iron 7 is separated from the magnet plate 4a, and the pin of the cylinder pin 4 is pushed out and inserted into the pin block 4b.

As shown in Figure 2, when the machine tool is in the state of up and down the workpiece, the shrinkable suction iron 7 moves to the magnetic suction plate 4a to make them attract each other, and the original extendable armor protection is integrated into one, and the cylinder latch device 1 pulls out the pin through the cylinder action , through the guide plate 5, the self-lubricating guide block 6, the overall armor protection quickly moves to the zero point of the machine tool with the moving axis, and then the open space is used for the upper and lower workpieces.

The beneficial effect of the invention is that the inverted telescopic armor protection provides a fully enclosed space, prevents iron filings from splashing, is compact and sealed, and can increase the feeding space and other structures. It has the advantages of simple structure, easy assembly, small installation space, safe and reliable locking and good sealing effect.
