Description

Technical Field

[0001] The utility model relates to the technical field of machine tool processing, in particular to a curtain installation structure for a machine tool. Background Technique

[0002] A numerical control machine tool is an automated machine tool equipped with a program control system, which can automatically process parts and is an indispensable production tool in modern manufacturing. A large amount of high-temperature debris will be generated during the cutting and processing operations of the machine tool, and cutting fluid is required for cooling and lubrication during the cutting process. The debris and cutting fluid are easy to splash everywhere, which will damage and corrode the internal parts of the machine tool such as guide rails and transmission parts. Therefore, the protection work of the machine tool is very important.

[0003] A protective curtain is usually arranged inside the machine tool to protect the internal hard guide rail, linear guide rail, ball screw or transmission rack of the machine tool from external corrosion and damage.

[0004] In the prior art, such as the Chinese patent with the application number 202210283042.5, the application publication number CN114533107A, and the invention name "A Portable Protective Curtain", the above patent discloses a portable protective curtain, which includes a first upper curtain assembly, a second upper curtain assembly, a first lower curtain assembly, a second lower curtain assembly and a third lower curtain assembly. The first lower curtain assembly, the second lower curtain assembly and the third lower curtain assembly are sequentially connected to each other from right to left. The first upper curtain assembly is located at the top of the third lower curtain assembly, and the second upper curtain assembly is located at the top of the second lower curtain assembly.

[0005] The above patent adopts a split structure, which is convenient for installation, disassembly and handling; it uses a lead-free protective curtain, which is safe and reliable. As is well known, during the working process, the protective curtain usually moves together with the machine tool equipment. However, in the prior art, the two ends of the protective curtain are not limited, so the protective curtain is prone to deviation during the long-term movement, resulting in friction between the protective curtain and the machine bed, generating noise and causing wear of the protective curtain, which has certain deficiencies. Content of the Utility Model

[0006] The purpose of the utility model is to provide a curtain installation structure for a machine tool to solve the problems raised in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solution: A curtain installation structure for a machine tool, including a machine tool body.

When the spindle box slides, it drives the first protective curtain to unfold or contract. A guiding member is arranged between the first protective curtain and the machine tool. The guiding member includes a first guiding portion and a second guiding portion. The first guiding portion is installed below the machine tool, and the second guiding portion is arranged above the machine tool. The first protective curtain is respectively connected to the first guiding portion and the second guiding portion through limiting members.

[0008] Further, the first guiding portion includes a guiding frame fixedly connected to the machine tool body. A limiting block is installed on the first protective curtain, and the limiting block is slidably connected inside the guiding frame.

[0009] Further, a first roller is installed at the bottom of the first protective curtain, and the first roller moves inside the guiding frame.

[0010] Further, a second roller is also installed at the top of the first protective curtain, and the second roller moves inside the second guiding portion.

[0011] Further, a second protective curtain is also slidably connected to the machine tool body, and the second protective curtain is slidably connected inside the guiding frame through a positioning member.

[0012] Further, the positioning member includes an extension block installed at the bottom of the second protective curtain. An extension groove adapted to the extension block is formed on the guiding frame, and the extension block is slidably connected inside the extension groove.

[0013] Further, a through-length pulling belt is arranged on the first protective curtain.

[0014] Further, multiple groups of elastic steel belts are arranged on the first protective curtain.

[0015] Further, a flow channel is formed inside the guiding frame, and an oil outlet is installed on the flow channel.

[0016] Further, the limiting block is made of ethylene steel.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: For the installation structure of the machine tool protective curtain, through the cooperation among the machine tool body, the first protective curtain, the first guiding part, the second guiding part, and the limiting part, etc., during the installation process of the first protective curtain, the lower part of the first protective curtain is installed on the first guiding part, and the top of the second protective curtain is installed on the second guiding part. Therefore, during the sliding process of the spindle box, it will drive the first protective curtain to unfold and contract. When the first protective curtain slides, it will drive the bottom of the first protective curtain to slide inside the first guiding part through the limiting part, and the top of the first protective curtain to slide inside the second guiding part through the limiting part. Thus, the stability of the first protective curtain during sliding can be greatly improved, avoiding the derailment of the first protective curtain, thereby preventing the first protective curtain from contacting the inside of the machine tool, further preventing the first protective curtain from rubbing against the machine tool, reducing noise, and at the same time being able to protect the first protective curtain, which is suitable for wide promotion and use;

[0018] Since the first protective curtain is inclined, during the equipment processing, oil, gas, etc. on the equipment will all fall on the surface of the first protective curtain. At this moment, the first protective curtain can guide the oil and gas to a predetermined area, avoiding the retention of oil and gas on the equipment, resulting in the pollution of the equipment body, and further improving the practicality of the protective curtain structure.
