Description

[Detailed description of the invention] [Industrial field of application] This invention relates to the opening/closing door of a splash guard installed around the work table and bed of a machine tool. It is related to.

[Conventional technology]

This machine tool squirts coolant toward the tip of the tool in order to improve cooling performance during machining, improve machinability, extend tool life, and remove chips. As a result, coolant liquid and chips scatter around the work table during machining, polluting the work environment. To prevent contamination of this working environment,
As shown in FIG. 4, the work table 2 of the machine tool 1
A splash guard 3 is installed around these to surround them, and this splash guard 3 prevents coolant liquid and chips from scattering.

Incidentally, the splash guard 3 is provided with slidable doors 5 and 6 in front of the work table 2 for loading and unloading the work 4, as shown in FIG. The opening/closing doors 5, 6 are constructed by, for example, as shown in FIG. 6, square gutter-shaped guide rails 7, 7 with a box-shaped cross section are opened at the upper front surface of the splash guard 3 and from both ends, with the central portion thereof being released. A guide roller 9 that fits into the guide rails 7, 7 is provided horizontally at the upper end of the opening/closing doors 5, 6, and a rolling roller 10 that sandwiches the lower guide rail 8 from above and below at the lower end. , 11 are provided, and the rolling rollers 10 and 11 support the load of the opening and closing doors 5 and 6, and the guide rollers 9 prevent them from falling down, allowing them to be opened and closed. Note that the guide rail 7,
If the guide rails 7 are installed side by side across the entire width, the worker may hit his or her head on the guide rail 7 and get injured when loading or unloading the workpiece 4, since the splash guard is also small in the case of a small machine tool. Further, in the case of a large-sized machine tool, the guide rail 7 becomes an obstacle when the workpiece 4 is moved in and out using the crane 12. Therefore, conventionally, as described above and as shown in FIG. 5, a space of an appropriate width was provided in the center of the guide rails 7, 7.

[Problem to be solved by the invention] Since there is no guide rail in the center, the opening/closing door 5,
When opening/closing 6, the center sides of the opening/closing doors 5, 6 are not guided by the guide rails 7, 7, so the guidance of the opening/closing doors 5, 6 becomes unstable, causing looseness and poor operability. It was difficult to match 5 and 6 accurately in the center, making opening and closing operations troublesome.

This idea is a machine tool that eliminates the guide rail in the center when opening and closing the door when loading and unloading workpieces, so that the opening and closing door can be opened and closed stably and smoothly, and at the same time, it does not give support when loading and unloading workpieces. The purpose of this invention is to provide a guide rail for splashes.

[Means to solve the problem]

The guide rail in this invention consists of a pair of square gutter-shaped fixed rails installed on both sides with an appropriate interval, a fixed pin and a locking pin suspended horizontally at the end of each fixed rail, and a A removable rail that is shaped like a square gutter and has a length that spans between a pair of fixed rails, has tongues on both sides of one end, and is swingably equipped with a locking member having a hook on the other end. One side of the removable rail is fixed so that it can rotate freely around the fixed pin of the fixed rail (also, if the removable rail is long, the tongue of the removable rail should be pushed towards the tongue of the fixed pin of one fixed rail). ) The hook of the locking member is locked to the locking pin of the other fixed rail, and the removable rail is installed between the fixed rails so that the removable rail, the locking member, and the pair of fixed rails are in a straight line. be.

[Effect]

The guide rail with the above structure is used when opening and closing the door.
Since the opening/closing door is guided over the entire area by a fixed rail and a removable rail, the opening/closing door does not rattle.
Moves easily. Furthermore, when loading or unloading a workpiece, by flipping up or removing the detachable rail, the workpiece can be loaded or unloaded safely and easily.
