Description

Technical Field

[0001] The utility model relates to the technical field of machining equipment, in particular to a vertical turret multi-axis compound machine tool. Background Art

[0002] The turret is one of the important components of CNC machine tools. When working, the motor drives the tool on the turret to perform drilling, milling, tapping and other processing on complex parts. Different tools can be switched by rotating the cutter head to meet the processing needs of different workpieces. It has the advantages of good flexibility, high processing precision, stable and reliable processing quality, high degree of production automation and high production efficiency.

[0003] like Figure 1 As shown, the existing vertical turret multi-axis compound machine tool usually includes a base 1, a shock-absorbing support seat 2, a column 3, a first worktable 4, a second worktable 5, a storage seat 6, a rotating seat 7, a clamping seat 8, a first slide rail 9, a first slide seat 10, a second slide rail 11, a first screw motor drive mechanism 12, a second screw motor drive mechanism 13, a tool disc 14, a tool arm 15, a connecting assembly 16, a column slide seat 17, a motor 18, a third screw motor drive mechanism 19, a third slide rail 20 and a third slide seat 24. During operation, the workpiece is mounted on the clamping seat 8, and the first screw motor drive mechanism 12 and the second screw motor drive mechanism 13 are used to drive the workpiece to move longitudinally and transversely respectively, and the clamped workpiece is driven to rotate horizontally through the rotating seat 7, so as to adjust the placement of the workpiece; the motor 18 is turned on to drive the cutter disc 14 to rotate, so as to select a tool of corresponding type and align it above the workpiece; the third screw motor drive mechanism 19 is turned on to drive the column slide 17 to rise and fall, thereby driving the tool to descend, and when the tool contacts the workpiece, the rotation of the tool is controlled by the rotary drive mechanism, so as to process the workpiece.

DETAILED DESCRIPTION

[0026] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0027] like Figure 2 and Figure 3As shown, a vertical turret multi-axis compound machine tool includes a base 100, a column 200, a turret 300 and a workbench 400, and also includes a driving mechanism 500 for driving the workbench 400 to achieve up and down lifting. The driving mechanism 500 includes a power assembly, a screw 520, a nut 530 and a mounting seat 540. The nut 530 is fixed to the base 100 through the mounting seat 540, the screw 520 is threadedly connected to the nut 530, and one end of the screw 520 is rotatably installed in the mounting seat 540, and the other end of the screw 520 is rotatably connected to the workbench 400. The power assembly is connected to the screw 520, and is used to drive the screw 520 to rotate, thereby driving the workbench 400 to lift up and down. The screw-type driving mechanism 500 has the advantages of simple structure, convenient installation, and precise adjustment, and can smoothly drive the workbench 400 to lift up and down, thereby making the application of the machine tool more flexible, ensuring that it can be applied to the processing needs of workpieces of different specifications or different application scenarios.

[0028] like Figure 2 and Figure 3 As shown, the power assembly includes a motor 511, a first bevel gear 512 and a second bevel gear 513. The motor 511 is fixed to the workbench 400, and the output shaft of the motor 511 is provided with the first bevel gear 512. The second bevel gear 513 is sleeved outside the screw 520 and meshes with the first bevel gear 512. The vertical transmission method using bevel gears has the advantages of large torque, high transmission efficiency and compact structure, which is conducive to driving the workbench 400 to rise and fall smoothly and fully optimize the layout space of the workbench 400.

[0029] like Figures 2 to 4 As shown, the workbench 400 includes a support seat 410 and a slide table disposed on the top of the support seat 410. A mounting groove 411 is disposed at the bottom of the support seat 410. A screw 520 vertically passes through the mounting groove 411 and is rotatably disposed on the support seat 410. A motor 511 is mounted on the outer wall of the support seat 410, and the output shaft of the motor 511 passes through the mounting groove 411 and is provided with a first bevel gear 512. Such a design can make the structure of the workbench 400 more compact and reasonable, and reduce unnecessary space waste.

[0030] like Figure 2 and Figure 3As shown, specifically, a first mounting hole 412 is provided on the top of the support seat 410, a first bearing 413 is provided between the screw rod 520 and the first mounting hole 412, and a second bearing 414 is provided between the second bevel gear 513 and the first mounting hole 412. A second mounting hole 415 is provided on the side wall of the support seat 410, and a shaft sleeve is installed in the second mounting hole 415; two third bearings 416 are provided between the output shaft and the shaft sleeve of the motor 511. In order to ensure the supporting function and improve the load bearing capacity, the first bearing 413 in this embodiment is preferably a tapered roller bearing, and the second bearing 414 and the third bearing 416 are preferably ball bearings.

[0031] like Figures 2 to 5 As shown, the mounting seat 540 is a conical cylindrical structure, and a nut 530 is fixed on the top of the mounting seat 540, which can play a firm supporting role, ensuring that the screw 520 can be rotatably mounted in the mounting seat 540, and realizing a transmission mode in which the screw 520 rotates and the nut 530 does not move. In order to facilitate the mounting seat 540 to be fixed on the base 100, the base 100 is provided with a mounting boss 140 adapted to the bottom of the mounting seat 540, and a through hole 141 is provided in the middle of the mounting boss 140 for the screw 520 to pass through, thereby making full use of the space of the base 100 and ensuring that the screw 520 has enough space to move up and down.

[0032] like Figures 2 to 4 As shown, the column 200 is provided with a guide rail 210 along its height direction, and the support seat 410 is provided with a guide groove 417 adapted to the guide rail 210 , thereby playing a guiding role to ensure that the workbench 400 is smoothly lifted up and down along the direction of the guide rail 210 .

[0033] like Figure 2 As shown, the slide includes a first slide 420 and a second slide 430. The first slide 420 can be longitudinally slidably arranged on the top of the support seat 410 through a first sliding mechanism; the second slide 430 can be transversely slidably arranged on the top of the first slide 420 through a second sliding mechanism. Preferably, both the first sliding mechanism and the second sliding mechanism use screw slides, and their working principles belong to the prior art and are not described here. In order to save installation space, the servo motor of the second sliding mechanism is arranged in the mounting groove 411 of the support seat 410 in this embodiment, and the transmission connection is realized through a synchronous pulley. In addition, in order to achieve a dust-proof effect, the first sliding mechanism and the second sliding mechanism are both covered with a telescopic accordion protective cover 440.

[0034] like Figure 2 , Figure 3 and Figure 5As shown, the base 100 is provided with a water collecting tank 110 below the workbench 400, and a flow hole 120 and a drainage tank 130 are provided at the bottom of the column 200. Specifically, the base 100 is provided with a support portion 150 for supporting the column 200, and a flow hole 120 connected to the water collecting tank 110 is provided at the bottom of the support portion 150, and the drainage tank 130 is provided on the outer wall of the base 100 and connected to the flow hole 120. Since the water collecting tank 110 is inclined toward the flow hole 120, it is convenient to discharge the waste water and waste generated during the processing, making the design of the machine tool more humanized.

[0035] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
