CNC numerical control machine tool

Abstract

The invention discloses a CNC numerical control machine tool. The CNC numerical control machine tool comprises a box body, wherein an inner cavity is formed in the box body, a workpiece is arranged inthe inner cavity, a movable frame body is arranged in the inner cavity in a sliding mode, symmetrical inner sliding cavities are formed in the two sides of the inner cavity in a communicating mode, aconnecting inner motor is arranged at the top of the inner sliding cavities, an output threaded rod is arranged on one side of the connecting inner motor in a power connection mode, the movable framebody is arranged in the inner sliding cavities in a sliding mode, the movable frame body is in threaded fit connection with the output threaded rod, the workpiece is arranged in the inner cavity, andclamping heat dissipation devices used for clamping the workpiece and carrying out relative liquid spraying heat dissipation on the workpiece are arranged on one side of the lower end wall of the movable frame body and one side of the lower end wall of the inner cavity respectively. According to the CNC numerical control machine tool, the workpiece can be clamped, and flowing cooling liquid is introduced into a middle hole so that the temperature of the workpiece in the machining process can be reduced from the interior.

Description

technical field [0001] The invention relates to the technical field of numerical control equipment, in particular to a CNC numerical control machine tool. Background technique [0002] There are many shortcomings in the existing equipment. First, the existing CNC machine tool equipment needs to use the corresponding fixture to clamp the rotary parts during the processing process, and then use the processing tool inside the machine tool to approach the rotary High-efficiency processing of such parts, there are many shortcomings in this processing process, first of all, most of the cooling during the processing of rotary parts is to spray coolant from the outside to cool the parts, but This causes the internal temperature of the rotary parts to not be transferred to the outer surface of the parts in time, which reduces the actual heat dissipation effect of the parts and makes the temperature distribution of the parts uneven, which greatly reduces the processing speed of the eq...

[0002] There are many shortcomings in the existing equipment. First, the existing CNC machine tool equipment needs to use the corresponding fixture to clamp the rotary parts during the processing process, and then use the processing tool inside the machine tool to approach the rotary High-efficiency processing of such parts, there are many shortcomings in this processing process, first of all, most of the cooling during the processing of rotary parts is to spray coolant from the outside to cool the parts, but This causes the internal temperature of the rotary parts to not be transferred to the outer surface of the parts in time, which reduces the actual heat dissipation effect of the parts and makes the temperature distribution of the parts uneven, which greatly reduces the processing speed of the equipment. The working efficiency of parts will greatly reduce the actual working efficiency of the equipment during the continuous and stable processing of the equipment, and it will not be convenient for the existing equipment to process rotary parts
