Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a mechanical slide table of a numerical control machine tool. Background Art

[0002] CNC machine tools are automated machine tools equipped with a program control system, which can effectively solve the problems of complex, precise, small batch and multi-variety parts processing. In the operation of CNC machine tools, mechanical slides are needed to adjust the position of the processed parts to meet the needs of part processing for part orientation adjustment.

[0003] For example, a CNC machine tool mechanical slide with the authorization announcement number "CN220388624U" drives the reciprocating screw to rotate through a servo motor, which can drive the moving slider and the horizontal turntable to move, so as to facilitate the adjustment of the position of external parts processing. During the external parts processing, the processing debris splashes onto the surface of the bottom plate. The reciprocating screw can be shielded and protected by the arc-shaped guard plate to prevent the debris from causing damage to the reciprocating screw. In addition, the debris is gathered on the surface of the bottom plate through the surrounding edge, and the debris can quickly fall into the slag collecting box from the lower slag opening, thereby facilitating the collection of debris and facilitating use. However, when the CNC machine tool mechanical slide needs to process the parts, the operator needs to manually fix the parts on the surface of the horizontal turntable by screwing the external clamping screw into the threaded hole. Since it takes a long time to fix the parts, the work efficiency is reduced. At the same time, since the height of the horizontal turntable is fixed, the distance between the processed parts and the processing tool is far after they are fixed, and the processing cannot be carried out. The operator needs to switch to other compatible slides for processing, which increases the working limitations. Utility Model Content

[0029] Working principle:

[0030] When the CNC machine tool mechanical slide is used:

[0031] Preparation process:

[0032] The operator fixes the base plate 1 on the processing station surface of the CNC machine tool, places the part between the two rubber pads, and starts the power supply of the two second motors 902. The output shaft of the second motor 902 rotates to drive the threaded rod 903 to rotate, thereby driving the slide bar 904 to slide along the slide groove processed on the protruding part of the inner wall of the first shell 901.

When the surface of the rubber pad 7 is in close contact with the surface of the part, the power supply of the two second motors 902 is turned off to achieve that the part can be quickly fixed.

[0033] Adjustment process:

[0034] Start the power supply of the first motor, the output shaft of the first motor 5 rotates to drive the workbench 2 to slide along the slide groove processed on the box body 3. When the workbench 2 drives the part to move to the appropriate position, turn off the power supply of the first motor 5, and then start the power supply of a third motor 402. The output shaft of the third motor 402 rotates to drive the worm 403 to rotate, thereby driving the worm wheel 404 to rotate. The rotation of the worm wheel 404 drives the gear 405 to roll along the tooth surface processed on the worm wheel 406. The rotation of the gear 405 drives the rotating rod 406 to move, thereby driving the transmission rod 407 to move. The movement of the transmission rod 407 drives the bending rod 408 to swing, thereby driving the connecting rod 409 to move. The movement of the connecting rod 409 drives the lifting rod 410 to slide along the surface of the protruding part of the inner wall of the second shell 401, so that the lifting rod 410 slides along the through hole processed on the second shell 401, and the lifting rod 410 moves upward to drive the box body 3 to move upward, thereby driving the part to move upward. When the part moves to the appropriate position, turn off the power supply of the four third motors 402, and start the CNC machine tool to process the part. So that different types of parts can be processed.
