Background
Along with the continuous promotion of digit control machine tool complete machine performance, the requirement of processing industry to digit control machine tool machining efficiency and stability also is higher more originally. The gap baffle is taken as a protection device for protecting important parts of machine tool movement, such as a screw rod, a bearing, a motor and a sliding guide rail, and the function and the quality stability of the gap baffle are also emphasized by more and more machine tool manufacturers.
The linear guide has two pull covers in each axial direction of the machine tool. The pull cover is used for protecting the linear guide rail and the ball screw while ensuring the movement of the moving part. Although most pull covers can protect, but the removal portion can't protect completely under with, in order to prevent that iron fillings foreign matter from the bottom entering lathe inside, damage linear guide rail and ball, then need increase clearance baffle and compensate.
The existing machine tool gap baffle is arranged between two pull covers, as shown in the figure five, after a protection 1 and a protection 2 are arranged in place, the mounting position of a protection plate is positioned between a sliding seat and an outer protection, the position of a mounting screw hole is uncertain, and the mounting space is seriously limited. And the baffle structure must compensate the manufacturing size error of the sliding seat, the manufacturing size error of the protection 1, the manufacturing size error of the protection 2 and the structural size difference of different linear guide rail pair brands, which causes the uncertainty of the installation position of the baffle.
The integrated structure can only compensate one-way errors, and the mounting holes are not well matched; and because the lathe structure reason, this department installation space is limited, needs two people cooperation during the installation, causes the problem of difficult installation.

Detailed Description
The following further description of the specific structure of the present invention,
the bidirectional adjustable guard plate of the machine tool comprises a first guard plate 1 and a second guard plate 2, wherein the first guard plate 1 is formed by fixing two intersected plane plates, and the two plane plates of the first guard plate 1 are vertical to each other.
The second guard plate 2 is composed of two intersecting plane plates, and the two plane plates of the second guard plate 2 are perpendicular to each other.
The plane plates of the first protection plate 1 and the second protection plate 2 are both strip-shaped rectangular plates, one of the two plane plates in the first protection plate 1 and the second protection plate is wide and narrow, and the cross sections of the first protection plate 1 and the second protection plate 2 are L-shaped.
The two plane plates forming the first protection plate 1 are provided with a long groove 3 at one end of the crossing position, the two plane plates forming the second protection plate 2 are provided with a long groove 3 at one end of the crossing position, the width of the long groove is equal to the plate thickness, and the length of the long groove is determined according to the actual situation.
The first guard plate 1 and the second guard plate 2 are inserted into each other along the elongated slot 3, when the wider plane plate of the two guard plates is horizontal, the other narrow plane is vertical, the horizontal plane plates of the two guard plates are in contact with each other, and the vertical plane plates of the two guard plates are in contact with each other.
The first guard plate and the second guard plate can be arbitrarily defined to be described in two positional relationships during product manufacturing:
when the wider plane plate of the first protection plate is positioned at the lower part of the wider plane plate of the second protection plate, the plane plate in the horizontal state in the first protection plate 1 extends downwards at the opening of the long groove, and the inclination angle between the inclined plane plate and the horizontal plane plate connected with the inclined plane plate is 45 degrees.
The inclined plane plate 4 is straight on the side of the elongated slot 3 and forms a slit 5 with a vertical plane plate in the first shield plate 1, and the vertical plane plate in the second shield plate is inserted into the slit 5.
When the wider plane plate of the second guard plate is positioned at the lower part of the wider plane plate of the first guard plate, the plane plate in the horizontal state in the second guard plate 1 extends downwards at the opening of the long groove, and the inclination angle between the inclined plane plate and the horizontal plane plate connected with the inclined plane plate is 45 degrees.
The inclined plane plate 4 is straight on the side of the elongated slot 3 and forms a slit 5 with the vertical plane plate in the second guard plate, and the vertical plane plate in the first guard plate is inserted into the slit 5.
The above two definitions of the shield plate according to the position relationship are provided for the convenience of understanding.
In order to fix the two guard plates, a wider plane plate of each of the first guard plate 1 and the second guard plate 2 is provided with a fixed slot hole 6, the length of the fixed slot hole is vertical to the length direction of the plane plate, and the end part of the fixed slot hole 6 is semicircular.
The fixed slot is fixed on two relatively moving parts of the machine tool, and the two parts move relatively to drive the two guard plates to move relatively, so that the extension and the shortening of the protection part are realized, and the space change of the part exposed outside caused by moving is adapted.
The first guard plate and the second guard plate are combined in a penetrating mode, so that the first guard plate and the second guard plate are only free in one direction, namely free in the length direction of the guard plane plate. The first protection plate and the second protection plate 2 can be adjusted in a movable mode along the direction shown in the figure 3, and therefore one direction can be adjusted.
Conventionally, after the first protection and the second protection are installed in place, the installation position of the guard plate is located between the sliding seat and the outer protection 10 as shown in fig. 5, and the installation space is severely limited. And the baffle structure must compensate the manufacturing size error of the slide seat, the manufacturing size error of the first protection, the manufacturing size error of the second protection and the structural size difference of different linear guide rail pair brands, so that the uncertainty of the installation position of the baffle is caused.
This device realizes the whole of backplate and reciprocates through setting up the fixed slot on the backplate. The self-adaptation to the mounted position is realized through backplate self structure like this to solve the unmatched problem of backplate mounting hole.
This backplate is owing to structural for first backplate 1 and the interlude hookup of second backplate 2, because will realize arrow head relative movement in figure 3, so the fit dimension tolerance is clearance fit, avoids the backplate to take place the condition of the emergence abnormal sound of two relative frictions of socket department under the vibrations environment.
However, the mounting positions of the first protection plate and the second protection plate are in the same plane during mounting, the mounting surfaces of the first protection plate and the second protection plate are not in the same plane, and the mounting positions of the plate 1 and the plate 2 are different by a certain plate thickness. Meanwhile, after the baffle is installed, the baffle socket can elastically deform, so that friction between the first protection plate and the second protection plate is increased, the purpose of increasing rigidity of the socket is achieved, and the self-locking phenomenon of the socket during installation is achieved.
The device can be more suitable for the characteristics of high protection level and limited installation space of a numerical control machine tool, can compensate for installation position errors, and improves the working stability and installation convenience of products.
The above description is only an embodiment of the present invention, and is not intended to limit the present invention, and any simple modifications, alterations, and equivalent changes made to the above embodiment according to the present invention shall fall within the protection scope of the technical solution of the present invention.
