Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tool technology, specifically relating to a high-precision power turret. Background Technology

[0002] The power turret is a key piece of equipment used in CNC machine tools, playing an irreplaceable role in improving the machining capabilities of the machine tool. It directly provides power control to the cutting tool, effectively improving the machining accuracy. In traditional power turrets, the motor is located outside the housing, transmitting power to the drive shaft via a synchronous belt. The end of the drive shaft is fixedly connected to the first gear, and the cutter head is fixedly connected to the second gear. The first and second gears mesh, and the transmission control is transmitted through the internal transmission system of the turret, and then the meshing transmission ratio is adjusted to transmit the control to the power tool holder to control the tool movement. The direct control effect on the tool is poor. Furthermore, the power source for many tool changing actions of the power turret cutter head relies on the transmission control introduced to the tool's main drive shaft through the clutch transmission. In this way, the overlap between the cutter head rotation and the power tool holder transmission system can affect each other under abnormal working conditions, which is detrimental to the use of the power turret. Moreover, the separate control structures of the two are relatively dispersed, which can easily affect the structural dimensions of the turret.

[0003] A high-precision power turret, as disclosed in patent number CN202323507414.7, includes a support frame; two sets of first guide rails are fixedly arranged on both sides of the top of the support frame, and a sliding seat is slidably arranged between the two sets of first guide rails; a first transmission component is movably arranged on the outside of the sliding seat, and a second transmission component is fixedly arranged on the outside of the first transmission component; a connecting structure is fixedly arranged inside the second transmission component, and a power turret device is fixedly installed on the top of the connecting structure.

[0004] The above solution still has certain technical defects in actual use. Since most power turrets generally use liquid cooling to extend into the interior of the power turret for heat exchange to achieve the purpose of heat dissipation, the medium flows through the interior of the turret box during the heat dissipation process, which can easily lead to leakage and reduce the service life of the internal components of the turret box.

[0005] According to the power turret with cooling device disclosed in patent number CN202420258974.9, by setting up a semiconductor hot end plate, a semiconductor cold end plate, a heat conduction embedded tube, and a cooling contact plate, the turret box is equipped with a cooling mechanism and a circulating heat exchange mechanism, which can centrally exchange heat for the power turret, improve the forced heat dissipation effect and stability of the power turret heat dissipation structure, and reduce the impact of the heat dissipation structure on the size of the power turret; by setting up a heat-conducting fixing sleeve, a coiling spring, a heat-absorbing exchange plate assembly, a telescopic fit cover, and electromagnetic rotating blades, the continuity of heat exchange and transfer inside the power turret is improved, the possibility of impurities carried by the circulating medium entering the power turret is reduced, and the safety of the power turret heat dissipation operation is improved; it can also improve the heat dissipation effect while absorbing some of the power turret vibration.

[0006] In the power turret with cooling device disclosed in CN202420258974.9, the proposed technical solution transfers heat through heat transfer before dissipating it. Although this can effectively solve the problem of medium leakage into the turret box, the heat needs to be transferred to the turret box body through the air inside the turret box due to the certain distance between the internal components and the turret box. This heat transfer efficiency is low and it is difficult to achieve efficient heat dissipation, which greatly reduces the heat dissipation efficiency. Therefore, we propose a power turret with high machining precision. Utility Model Content

[0007] The purpose of this invention is to provide a high-precision power turret to solve the existing problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-precision power turret, comprising a turret housing, a heat dissipation groove, a heat-conducting plate, and contact posts. The turret housing has heat dissipation grooves on both outer sides. A heat-conducting plate is fixedly embedded in the inner wall of one side of the heat dissipation groove. One side of the heat-conducting plate extends into the interior of the turret housing. Several contact posts are provided on the surface of the heat-conducting plate extending into the interior of the turret housing. A cooling fin is fixedly connected to the surface of the heat-conducting plate inside the heat dissipation groove via thermally conductive silicone grease. The heat-absorbing end of the cooling fin is fixedly connected to the heat-conducting plate, and the heat-releasing end of the cooling fin is fixedly connected to a heat dissipation fin via thermally conductive silicone grease. The heat dissipation fin is disposed inside the heat dissipation groove. A heat insulation layer is filled between the heat-conducting plate and the heat dissipation fin. The heat insulation layer wraps around the outer periphery of the cooling fin but does not affect the contact between the cooling fin and the heat-conducting plate and the heat dissipation fin.

[0009] Preferably, a sealing plate is provided on the side of the heat dissipation groove away from the heat conduction plate. The outer perimeter of the sealing plate is fixed and sealed to the inner wall of the heat dissipation groove by sealant. An air inlet and an exhaust outlet are respectively opened on the inner side of the top and bottom ends of the sealing plate. A cooling fan is fixedly installed inside the air inlet and the exhaust outlet.

[0010] Preferably, a heat-conducting rod is provided on the outer periphery of the cooling chip, the heat-conducting rod is arranged around the cooling chip, and the two sides of the heat-conducting rod are in contact with the heat-conducting plate and the heat dissipation fins respectively. The heat insulation layer also wraps around the outer periphery of the heat-conducting rod but does not affect the contact between the heat-conducting rod and the heat-conducting plate and the heat dissipation fins.

[0011] Preferably, a dustproof net is provided on the inner side of both the air inlet and the exhaust outlet, and the dustproof net is fixedly installed inside the air inlet and the exhaust outlet.

[0012] Preferably, a cutterhead clutch is provided at one end of the turret box, and the cutterhead is assembled in the turret box through the provided cutterhead clutch.

[0013] Preferably, a servo motor is provided at the end of the turret housing away from the cutter head, and the output shaft of the servo motor extends into the interior of the turret housing.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting contact posts on one side of the heat-conducting plate inside the heat sink, the contact posts extend into the interior of the turret box, allowing them to directly contact the interior of the turret box. In conjunction with the cooling fins and heat sink, the heat absorbed by the contact posts is transferred sequentially to the interior of the heat sink. Finally, the heat is ventilated and cooled through the cooling fans in the air inlet and exhaust outlet, thereby achieving the purpose of efficient heat dissipation of the interior of the turret box.

[0016] 2. By setting heat-conducting rods on the outer periphery of the cooling chip, and utilizing the contact between the heat-conducting rods and the heat dissipation fins, the contact area on both sides of the cooling chip is increased, thereby improving heat transfer efficiency. This indirectly achieves the goal of improving heat dissipation efficiency. In conjunction with this, a heat insulation layer is set to wrap the cooling chip and the heat-conducting rods with the heat dissipation fins without affecting their contact. This prevents the heat absorption end of the cooling chip from being affected by the temperature inside the heat dissipation groove, which could reduce the operating efficiency of the cooling chip and ensure stable operation of the cooling chip, thus guaranteeing the stability of efficient heat dissipation.

[0024] Specifically, a sealing plate 12 is provided on the side of the heat sink 5 away from the heat conduction plate 6.

The contact post 7 extends into the interior of the turret box 1, allowing it to directly contact the interior of the turret box 1. This improves the efficiency of heat transfer from inside the turret box 1 to the heat sink 5. After the heat-conducting plate 6 absorbs the heat from the contact post 7, the heat is further absorbed by the heat-absorbing end of the cooling fin 9, and then transferred to the heat dissipation fins 11 by the heat-releasing end of the cooling fin 9.
