When the extrusion plate approaches the fixed seat along the axis of the reciprocating screw, the extrusion plate squeezes the surface of the airbag and drives the air in the airbag into the sliding cavity through the blowing hole and impacts the surface of the sliding seat, and the sliding seat is fully in contact with the air and performs heat exchange; when the extrusion plate moves away from the fixed seat along the axis of the reciprocating screw, the extrusion plate drives the airbag to prop up, and the air in the sliding cavity enters the inner cavity of the airbag through the blowing hole, driving the outside air to enter the sliding cavity and fully contact the surface of the sliding seat for heat exchange, promoting the air flow in the sliding cavity, realizing cooling of the sliding seat, making it difficult for the sliding seat to deform due to long-term operation in a high temperature state, thereby improving the machining accuracy of the tool on the workpiece.

The spherical surface of the balls 62 protruding from the slide rail 5 is in rolling contact with the inner wall of the slide groove 21, and the rolling friction replaces the sliding friction, thereby reducing the friction between the slide rail 5 and the inner wall of the slide groove 21 and improving the stability of the slide rail 5 sliding on the inner wall of the slide groove 21.

[0037] Reference Figure 1 and Figure 5 An oil storage chamber 52 for storing oil is provided on the top surface of the slide rail 5. A closing bolt 7 is threadedly connected to the cavity opening of the oil storage chamber 52. The outer peripheral surface of the closing bolt 7 is pressed against the inner wall of the oil storage chamber 52 to form a seal, so that foreign matter is not easy to enter the oil storage chamber 52, thereby ensuring the stability of oil storage in the oil storage chamber 52; a plurality of oil supply holes 53 are provided at intervals on the inner wall of the rotating chamber 51 of the oil storage chamber 52. The oil supply holes 53 correspond to and are connected with the rotating chamber 51 one by one. The oil in the oil storage chamber 52 is coated on the spherical surface of the steel ball through the oil supply holes 53 to lubricate the spherical surface of the steel ball. The spherical surface of the ball 62 rolls in contact with the inner wall of the slide groove 21. The ball 62 applies the oil to the inner wall of the slide groove 21 to lubricate the inner wall of the slide groove 21, thereby further reducing the friction between the inner wall of the slide groove 21 and the slide rail 5, thereby extending the service life of the CNC turret.

[0038] Reference Figure 1 and Figure 5 The opening and closing assembly 63 corresponds to the oil supply hole 53 one by one and is installed on the inner wall of the oil supply hole 53.

In the embodiment of the present application, the material of the elastic block 633 is memory alloy with a good thermal expansion coefficient. The material of the elastic block 633 can be rubber or silicone. In the embodiment of the present application, the elastic block 633 has a good thermal expansion coefficient. The material of the elastic block 633 is rubber, which has a certain deformation ability. Multiple elastic blocks 633 are fixed at intervals on the inner wall of the oil supply hole 53 near the oil storage chamber 52. Multiple elastic blocks 633 are spliced ​​to form a circular plate and close the oil supply hole 53. One end of the thermal expansion and contraction ring 631 in the axial direction is fixed on the inner wall of the oil supply hole 53 near the rotating chamber 51, and the other end of the thermal expansion and contraction ring 631 in the axial direction is coaxially fixed on the end face of the starting tube 632. The tube surface of the starting tube 632 in the axial direction away from the thermal expansion and contraction ring 631 faces the elastic block 633.

[0039] Reference Figure 1 and Figure 5The ring surface of the thermal expansion and contraction ring 631 away from the starting tube 632 rolls in contact with the spherical surface of the ball 62. When the ball 62 converts part of its kinetic energy into thermal energy, the ball 62 transfers the thermal energy to the thermal expansion and contraction ring 631. The thermal expansion and contraction ring 631 heats up and expands. The thermal expansion and contraction ring 631 drives the starting tube 632 to slide along the inner wall of the oil supply hole 53 toward the elastic block 633. The tube surface of the starting tube 632 squeezes the elastic block 633. The elastic block 633 is deformed under pressure, and the sealing effect of the elastic block 633 on the oil supply hole 53 disappears. The oil in the oil storage chamber 52 enters the rotating chamber 51 through the oil supply hole 53. The oil covers the spherical surface of the ball 62 in the rotating chamber 51, thereby realizing the directional opening of the oil supply hole 53, reducing the loss of the oil in the oil storage chamber 52, and reflecting the concept of environmental protection.

The sliding direction of the float 611 and the height direction of the fixing seat 1 are parallel to each other. The contact switch 613 is fixed to the inner wall of the warning chamber 54 away from the closing bolt 7. The warning light 612 is fixed to the surface of the slide rail 5 by bolts. The warning light 612 is electrically connected to the contact switch 613. When the oil storage chamber 52 is in a state of oil leakage, the warning light 612 is electrically connected to the contact switch 613. When the oil in the oil chamber 52 continuously enters the rotating chamber 51 from the oil supply hole 53, the liquid level of the oil in the oil storage chamber 52 continuously decreases, driving the float 611 to slide along the inner wall of the warning chamber 54 toward the direction close to the contact switch 613. The contact switch 613 abuts against the surface of the float 611 and is turned on, and the warning light 612 is energized and illuminates, thereby alerting the staff to supply oil to the oil storage chamber 52 in time, so that the staff does not need to observe the changes in the oil level in the oil storage chamber 52 all the time, thereby improving the convenience of using the CNC turret.

[0041] The implementation principle of a CNC turret in the embodiment of the present application is as follows: when the CNC turret is in use, the motor starts and drives the tool to rotate through the main shaft to process the surface of the workpiece. During the operation of the motor, part of the electrical energy is converted into thermal energy. The motor is installed on the surface of the slide 2, and the motor transfers part of the thermal energy to the slide 2 to achieve the heating of the slide 2; at the same time, when the power motor 43 starts and drives the reciprocating screw 42 to rotate, the extrusion plate 45 approaches the fixed seat 1 along the axis of the reciprocating screw 42, and the plate surface of the extrusion plate 45 squeezes the blast airbag 44 and drives the air in the blast airbag 44 to enter the sliding cavity 11 through the one-way valve 46 and the blowing hole 12 to impact the surface of the slide 2, and the air The air is in full contact with the surface of the slide seat 2 and heat exchange is carried out, so as to cool the slide seat 2 and prevent the slide seat 2 from being deformed due to long-term operation at high temperature, thereby improving the machining accuracy of the tool on the workpiece; when the extrusion plate 45 moves away from the fixed seat 1 along the axis of the reciprocating screw 42, the extrusion plate 45 drives the airbag 44 to open, and the outside air passes through the one-way valve 47 and the air inlet 451 in turn and enters the inner cavity of the airbag 44, so as to achieve directional replenishment of air in the inner cavity of the airbag 44, ensure the stability of the air flow in the sliding cavity 11, and make the slide seat 2 in full contact with the air and heat exchange, thereby improving the cooling efficiency of the slide seat 2.

[0042] At the same time, when the air temperature in the cooling chamber rises, the air in the cooling chamber transfers heat energy to the thermal expansion and contraction part 4112 through the fixed seat 1, the thermal expansion and contraction part 4112 heats up and expands and drives the tooth portion 4113 to approach the cooling impeller 49, and the tooth surface of the tooth portion 4113 engages with the tooth surface of the cooling gear 410, driving the cooling impeller 49 to rotate on the inner wall of the sliding chamber 11, promoting the air flow in the sliding chamber 11, so that the air is fully in contact with the inner wall of the sliding chamber 11 and heat exchange is performed, thereby achieving cooling of the fixed seat 1.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
