Description

Technical Field

[0001] The utility model relates to the technical field of five-axis turning and milling compound machining centers, in particular to a vertical double-spindle five-axis turning and milling compound machining center. Background Art

[0002] The five-axis milling machining center has the characteristics of high efficiency and high precision. The workpiece can complete complex processing in one clamping. It can adapt to the processing of modern molds such as automotive parts and aircraft structural parts. The five-axis machining center has five axes: x, y, z, a, and c. It is good at spatial curved surface processing, special-shaped processing, hollow processing, punching, oblique holes, bevel cutting, etc. The "pentahedron machining center" is similar to the three-axis machining center, except that it can do five faces at the same time, but it cannot do special-shaped processing, oblique holes, cutting bevels, etc. In order to improve the working efficiency of the five-axis milling machining center, some five-axis milling machining centers will be equipped with two tool spindles for processing workpieces.

[0003] Publication number "CN214264641U" provides a vertical dual-spindle five-axis turning and milling compound machining center, in which a first slide plate and a second slide plate are provided on the bed, and the first vertical worktable and the second vertical worktable are used to clamp the workpiece to be processed respectively; a Z-guide rail and a Z-slide plate are provided on the column, and a machining spindle is provided on the rotary worktable, and the rotary worktable drives the machining spindle to rotate and position it at any angle. This compound machining center alternately installs and removes workpieces on the first vertical worktable and the second vertical worktable, drives the rotary worktable to perform Z-positioning through Z-sliding, and performs vertical, horizontal and other arbitrary positioning processing on the machining angle of the machining spindle through the rotary worktable. The machining of parts that require multi-faceted machining can be completed by clamping the workpiece once, significantly improving the machining accuracy, and the machining efficiency of the workpiece can be significantly improved by alternately installing the workpiece to be processed and removing the completed workpiece;

[0004] However, the above device still has the following problems during implementation:

[0005] In the prior art, the vertical dual-spindle five-axis turning and milling compound machining center is often used to process some large and batch-processed workpieces. The dual-spindle design improves the machining efficiency, but it also means that the tool will wear faster. To address the tool wear problem, a nozzle is usually used to extract coolant from the coolant tank during workpiece machining and spray it on the tool to achieve a cooling effect. However, considering that the workload of the vertical dual-spindle five-axis turning and milling compound machining center will be greater, the coolant will heat up during the cooling process of the circulation spray. At the same time, the five-axis turning and milling compound machining center is in a relatively sealed environment during the machining process, and the hot air cannot evaporate, which will make it difficult for the coolant circulated by the nozzle to meet the cooling effect, thereby reducing the practicality of the five-axis turning and milling compound machining center.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0036] Embodiment 1:

[0037] A vertical dual-spindle five-axis milling machining center comprises a five-axis milling machining center 1, a cooling box 2, a spindle box 3, two nozzles 4 and two machining spindles 5, wherein the cooling box 2 is fixedly mounted on the bottom of the five-axis milling machining center 1, the spindle box 3 is fixedly mounted on the top of the five-axis milling machining center 1, the machining spindle 5 is transmission-connected to the bottom of the spindle box 3, the nozzle 4 is located at the bottom of the spindle box 3, one side of the cooling box 2 is fixedly connected with two exhaust pipes 6, and one side of the five-axis milling machining center 1 is provided with an exhaust mechanism, which can discharge the hot air generated by the coolant from the interior of the cooling box 2;

[0038] The swing mechanism is fixedly arranged on the exhaust mechanism, and the coolant can be swung in the cooling box 2 through the swing mechanism.

[0039] One implementation of the first embodiment of the present invention is as follows: the exhaust mechanism includes a mounting frame 7 fixedly arranged on one side of the five-axis turning and milling compound machining center 1, a motor 8 is fixedly connected to one side of the mounting frame 7, a first bevel gear 9 is fixedly connected to the surface of the output end of the motor 8, both sides of the first bevel gear 9 are meshedly connected to the second bevel gear 10, one side of the second bevel gear 10 is fixedly connected to a traction rod 11, one end of the traction rod 11 passes through the interior of the exhaust pipe 6, and is fixedly connected to a third bevel gear 12, and one side of the third bevel gear 12 is meshedly connected to a fourth bevel gear 13;

[0040] A rotating rod 14 is fixedly connected to one side of the fourth bevel gear 13, and an exhaust fan blade 15 is fixedly connected to one end of the rotating rod 14;

[0041] In this embodiment, it is considered that the five-axis turning and milling compound machining center 1 is in a relatively sealed environment during machining, and the hot air cannot evaporate, which will cause the coolant circulated by the nozzle 4 to be difficult to meet the cooling effect. Therefore, through the exhaust pipe 6 and the exhaust mechanism, the first bevel gear 9 can be driven to rotate by starting the motor 8. During the rotation of the first bevel gear 9, the second bevel gear 10 will be driven to rotate. The second bevel gear 10 will drive the traction rod 11 and the third bevel gear 12 to rotate around the bearing seat on the first support frame 24. At the same time, the third bevel gear 12 is meshed with the fourth bevel gear 13, so it will drive the fourth bevel gear 13 to rotate. The fourth bevel gear 13 will drive the rotating rod 14 and the exhaust fan blades 15 to rotate, and the hot air in the cooling box 2 will be discharged from the exhaust pipe 6;

[0042] The invention solves the problem that the coolant circulated by the nozzle 4 is unable to satisfy the cooling effect, considering that the five-axis turning-milling compound machining center 1 is in a relatively sealed environment during machining and hot air cannot evaporate.

[0043] Preferably, two first support frames 24 are fixedly connected to the rear side of the cooling box 2, and the inner wall of the first support frame 24 is rotatably connected to the surface of the traction rod 11 through a bearing seat, and the inner wall of the exhaust pipe 6 is fixedly connected to the second support frame 25, and the inner wall of the second support frame 25 is rotatably connected to the surface of the rotating rod 14 through a bearing seat;

[0044] In this embodiment, the first support frame 24 and the second support frame 25 are provided to support structures such as the traction rod 11 and the rotating rod 14. At the same time, the smoothness of the rotation process can be improved by the rotation connection of the bearing seat.

[0045] Preferably, a filter screen 26 is fixedly connected to the inner wall of the exhaust pipe 6, which can prevent debris from entering the cooling box 2 through the exhaust pipe 6;

[0046] In this embodiment, the filter screen 26 can play an isolating role and prevent some debris from entering the interior of the cooling box 2 from the exhaust pipe 6.

[0047] Embodiment 2:

[0048] On the basis of the first embodiment, the exhaust mechanism in this embodiment can generate suction by rotating the exhaust fan blades 15 to discharge the hot air in the cooling box 2, thereby cooling the coolant. However, the exhaust mechanism can only discharge the hot air on the surface of the coolant, but the hot air in the bottom coolant is difficult to discharge. The swing mechanism in this application includes a swing plate 16 movably arranged inside the cooling box 2;

[0049] The output end of the motor 8 passes through the interior of the cooling box 2 and is fixedly connected to a rotating disk 17. A transmission rod 18 is fixedly connected to one side of the rotating disk 17. A transmission block 19 is sleeved on the surface of the transmission rod 18. One side of the transmission block 19 is fixedly connected to one side of the swing plate 16. A transmission groove 20 used in conjunction with the transmission rod 18 is provided on one side of the transmission block 19.

[0050] In this embodiment, it is considered that the exhaust mechanism can only discharge the hot air on the surface of the coolant, but it is difficult to discharge the hot air in the coolant at the bottom. Therefore, through the swing mechanism, the output end of the motor 8 can rotate while the rotating disk 17 is driven to rotate, and the rotating disk 17 drives the transmission rod 18 to rotate. During the rotation of the transmission rod 18, the surface of the transmission groove 20 is squeezed, so that the transmission block 19 and the swing plate 16 swing back and forth, so that the coolant swings, increasing the contact area between the coolant and the air, and thus improving the efficiency of hot air discharge;

[0051] Solved the problem that the exhaust cooling method of the exhaust mechanism can only discharge the hot air on the surface of the coolant, but the hot air in the bottom coolant is difficult to discharge;

[0052] It should be noted that during the rotation of the transmission rod 18, the trajectory of the transmission groove 20 is a reciprocating movement up and down. During this process, when the surface of the transmission rod 18 presses the inner wall of the transmission groove 20, it will squeeze the transmission block 19 to move back and forth.

[0053] Preferably, a guide block 21 is fixedly connected to one side of the transmission block 19, and a guide groove 22 for use with the guide block 21 is provided on the inner wall of the cooling box 2;

[0054] In this embodiment, the guide block 21 and the guide groove 22 can squeeze the inner wall of the transmission groove 20 during the rotation of the transmission rod 18, so that the transmission block 19 and the swing plate 16 can only move back and forth left and right along the trajectory of the guide block 21 and the guide groove 22, thereby limiting the movement trajectory.

[0055] Preferably, the surface of the swing plate 16 is provided with through holes 23, and the number of the through holes 23 is several;

[0056] In this embodiment, by providing the through hole 23, the resistance encountered by the swing plate 16 during the reciprocating movement can be reduced, and the coolant can also flow through the through hole 23, thereby improving the swinging effect.

[0057] Working principle: By starting the motor 8, the first bevel gear 9 is driven to rotate, and the first bevel gear 9 will drive the second bevel gear 10 to rotate during the rotation process, and the second bevel gear 10 will drive the traction rod 11 and the third bevel gear 12 to rotate around the bearing seat on the first support frame 24, and at the same time, the third bevel gear 12 is engaged with the fourth bevel gear 13, so it will drive the fourth bevel gear 13 to rotate, and the fourth bevel gear 13 will drive the rotating rod 14 and the exhaust fan blade 15 to rotate, so that the hot air in the cooling box 2 is discharged from the exhaust pipe 6;

[0058] At the same time, when the output end of the motor 8 rotates, the rotating disk 17 will be driven to rotate, and the rotating disk 17 will drive the transmission rod 18 to rotate. During the rotation of the transmission rod 18, the surface of the transmission groove 20 will be squeezed, so that the transmission block 19 and the swing plate 16 will swing back and forth left and right, so that the coolant will swing, increasing the contact area between the coolant and the air, thereby improving the efficiency of hot gas discharge.

[0059] It should be noted that the motor 8 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art, and the specific composition and principle of the power supply of the motor 8 are clear to those skilled in the art, so they are not described in detail.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
