The slide rail positioning device of the high-speed vertical machining center is a device used to ensure the accurate positioning of the slide rail movement during the machining process of the machining center;

[0003] Since the existing high-speed vertical machining center can only achieve a one-way movement control effect when the workbench moves along the slide rail, and the slide rail is actually installed with a high-speed vertical machining center operation box at both ends, once the slide rail drives the workbench to conflict with the operation box, it is very easy to cause the processing parts to be misaligned or even cause damage to the device. However, the existing device has not made improvements to this problem, and the overall practical effect is poor. Utility Model Content

When the slide rail is actually installed, both ends of the slide rail are provided with a high-speed vertical machining center operating box. Once the slide rail drives the working table to conflict with the operating box, it is very easy to cause the processing parts to be misplaced or even cause the device to be damaged.

The setting of the limiting support plate 42 here has a supporting and protective effect on the processing table 3 and the auxiliary support plate 41, so that the effect of buffer protection is achieved through the extrusion and contraction deformation of the above-mentioned support spring 44.

[0024] The portable installation mechanism 5 includes a limit mounting block 51, a first thread groove 52 and a second thread groove 53. The limit mounting block 51 is symmetrically arranged on the side outer wall of the adjusting box 2 at the bottom end. The top outer wall of the limit mounting block 51 is provided with a first thread groove 52, and the top outer wall of the workbench 1 is symmetrically provided with two groups of second thread grooves 53. The first thread groove 52, the second thread groove 53 and the positioning bolt 54 are threadedly installed. The opening diameter of the first thread groove 52 and the opening diameter of the second thread groove 53 are equal. When it is necessary to remove the adjusting box 2 from the top of the workbench 1, at this time, it is only necessary to screw out the positioning bolts 54 from the inside of the limit mounting block 51 in turn, so that the adjusting box 2 changes from a fixed state to an active state, and then the adjusting box 2 can be directly taken out from the inside of the device. When installing, it is first necessary to adjust the adjusting box 2 to a suitable position and then align the position of the first thread groove 52 with the position of the second thread groove 53 above the workbench 1, and then screw the positioning bolt 54 through the first thread groove 52 to the inside of the second thread groove 53 to complete the locking installation of the adjusting box 2.

[0025] The driving control mechanism 6 includes a driving motor 61 and a reciprocating screw 62. The driving motor 61 is arranged on the inner side wall of the adjusting box 2. The driving motor 61 is connected to the outer side wall of the reciprocating screw 62. The outer side wall of the reciprocating screw 62 is rotatably mounted on the inner side wall of the adjusting box 2. An auxiliary support bar 63 is arranged parallel to the side of the reciprocating screw 62. Both ends of the auxiliary support bar 63 are connected to the inner side wall of the adjusting box 2. Positioning blocks 64 are arranged on the outside of the reciprocating screw 62 and the auxiliary support bar 63. The top outer wall and the bottom outer wall of the positioning block 64 are both slidably mounted on the inner side wall of the adjusting box 2. The outer side wall of the positioning block 64 at the bottom end is symmetrically provided with an extension plate 65. The outer side wall of the extension plate 65 is parallel to the side of the auxiliary support plate 41. The outer wall of the side is connected; when it is necessary to control the movement of the processing table 3, it is necessary to turn on the drive motor 61 first. When the drive motor 61 is turned on, it will automatically drive the reciprocating screw 62 to rotate and then drive the positioning block 64 to move. Here, due to the setting of the auxiliary support bar 63, the reciprocating screw 62 will only drive the positioning block 64 to realize the horizontal sliding trajectory movement when rotating, and then the movement of the positioning block 64 will automatically drive the extension plate 65 to move and then drive the auxiliary support plate 41 to move. Subsequently, the movement of the auxiliary support plate 41 will drive the processing table 3 to move. When the processing table 3 moves to the appropriate position, the drive motor 61 can be controlled to be turned off. It is noted here that the drive motor 61 has a self-locking function. After being turned off, the processing table 3 can still maintain the unchanged position after moving.

[0026] When the utility model is in use, since control boxes are arranged on both sides of the high-speed vertical machining center, when the machining table 3 moves to the sidemost edge of the device and conflicts with the above-mentioned control box, the conflicting support plate 45 will automatically move to the side under the extrusion force, and at this time, the support spring 44 will be in a contracted state under the extrusion of the conflicting support plate 45 and will contract into the inside of the conflicting groove 43, and the setting of the limiting support plate 42 here plays a supporting and protective effect on the machining table 3 and the auxiliary support plate 41, so as to achieve the effect of buffering and protecting through the extrusion and contraction deformation of the above-mentioned support spring 44, and when it is necessary to remove the adjusting box 2 from the top of the working table 1, at this time, it is only necessary to screw out the positioning bolts 54 from the inside of the limiting mounting block 51 in turn, so that the adjusting box 2 changes from a fixed state to an active state, and then directly take out the adjusting box 2 from the inside of the device. When installing, it is first necessary to adjust the adjusting box 2 to a suitable position and align the position of the first thread groove 52 with the position of the second thread groove 53 above the working table 1, and then screw the positioning bolt 54 through the first thread groove 52 to the inside of the second thread groove 53 to complete the locking installation of the adjusting box 2;

[0027] When it is necessary to control the movement of the processing table 3, it is necessary to turn on the drive motor 61 first. When the drive motor 61 is turned on, it will automatically drive the reciprocating screw 62 to rotate and then drive the positioning block 64 to move. Here, due to the setting of the auxiliary support bar 63, the reciprocating screw 62 will only drive the positioning block 64 to realize the horizontal sliding trajectory movement when rotating, and then the movement of the positioning block 64 will automatically drive the extension plate 65 to move and then drive the auxiliary support plate 41 to move. Then the movement of the auxiliary support plate 41 will drive the processing table 3 to move. When the processing table 3 moves to the appropriate position, the control drive motor 61 can be turned off. It is noted here that the drive motor 61 has a self-locking function. After being turned off, the processing table 3 can still maintain the unchanged position after moving.

[0028] It is noted here that the above-mentioned drive motor 61 can be powered by existing technology, whether it is powered by a power supply component or an external power cord, which belongs to the existing conventional operating technical means and will not be described in detail here.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
