Separation type knife library protection device for moving beam gantry machining center

Abstract

The invention discloses a separation type knife library protection device for a moving beam gantry machining center. A protection door base structure adopts a welding piece framework to guarantee thewhole rigidity, and a first sliding unit arranged in the middle of a knife library door and used for load bearing and guiding, a second sliding unit arranged at the bottom for guiding, and a third sliding unit arranged on the top for guiding are included. A driving unit of the separation type knife library protection device is fixed to the middle portion of a base and certain protection is added,and the driving unit is connected with the knife library door through a middle connection piece so that the reciprocating motion of the knife library door can be manipulated; and noise generated due to waggling when the knife library door fast moves and deformation generated after use for a period of time are avoided. The extreme positions of a knife library protection door switch are each additionally provided with a buffering device, and impacting and deforming generated due to impacting of the knife library door switch are avoided. The bottom of a knife library protection base is supportedon the ground by using foot cups so that a gap between the mechanism and a machine tool body protection chamber can be conveniently adjusted and interference can be avoided.

Description

technical field [0001] The invention specifically relates to a separate tool magazine protection device for a moving beam gantry machining center. Background technique [0002] There are many types of tool magazines for CNC machine tools, but for CNC machine tools that undertake mass production tasks, the automation of the tool magazine sliding doors is poor, requiring a lot of human intervention. Maintenance is time-consuming and labor-intensive due to the lack of maintenance windows on CNC machine tools. The protection design of the tool magazine in the prior art has the following disadvantages: 1. There are too few windows, which is inconvenient for maintenance; 2. The protection performance is not good, and it is easy to splash cutting fluid and iron filings and affect the life of the tool magazine components and cylinders; 3. The sliding door of the tool magazine is unstable during the movement, which will cause friction with the outer protection of the tool magazine, r...

[0002] There are many types of tool magazines for CNC machine tools, but for CNC machine tools that undertake mass production tasks, the automation of the tool magazine sliding door is poor, requiring a lot of human intervention. Due to the lack of maintenance windows on CNC machine tools, it is time-consuming and labor-intensive.

The protection design of the tool magazine in the prior art has the following disadvantages: 1. There are too few windows, which is inconvenient for maintenance; 2. The protection performance is not good, and it is easy to splash cutting fluid and iron filings and affect the life of the tool magazine components and cylinders; 3. The sliding door of the tool magazine is unstable during the movement, which will cause friction with the outer protection of the tool magazine, resulting in noise, easy deformation and other problems
