Description

Technical Field

[0001] The utility model relates to the technical field of direct-drive turntables, and more specifically, to a composite turntable with nested direct-drive transmission and roller cam transmission. Background Art

[0002] A direct drive rotary table is a device that uses direct drive technology. Its core feature is that it does not use traditional mechanical transmission components (such as gears, belts, etc.). Ordinary direct drive rotary tables are traditional worm gear structures, which have low working speeds and noise. They can only rotate at a low speed and cannot run at high speeds.

[0003] After searching, the Chinese patent with the announcement number CN220825664U discloses a high-speed direct-drive turntable. This utility model is used in CNC machine tools as the fourth axis of the machine tool to achieve multi-axis composite precision machining. It is directly driven by a high-speed torque motor with low noise, no backlash, and compact structure, so that the turntable rotates at high speed.

[0004] When the above-mentioned direct-drive turntable is in use, the structure includes a rotating shaft, a turntable arranged at one end of the rotating shaft, a rotor arranged on the rotating shaft, and a stator sleeved on the rotor. The structure is simple and is not suitable for occasions with high processing precision requirements and relatively strong rigidity of processing parts. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a composite turntable with nested direct drive transmission and roller cam transmission, aiming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a composite turntable with nested direct drive transmission and roller cam transmission, comprising a direct drive turntable body, a second limit plate is fixedly connected to the bottom end of the direct drive turntable body, a first limit plate is movably provided on the top of the direct drive turntable body, a roller cam turntable body is movably sleeved on the outer side of the direct drive turntable body, four fixing bolts are movably provided on the top of the first limit plate, and the bottom ends of the four fixing bolts all pass through the first limit plate and are threadedly connected to the direct drive turntable body.

[0007] Furthermore, the top and bottom ends of the roller cam turntable body are fixedly connected with side rings, and the first limit plate and the second limit plate are respectively located inside the two side rings.

[0008] It can be seen that in the above technical solution, two side rings are used to facilitate the protection of the first limiting plate and the second limiting plate.

[0009] Furthermore, two second gaskets are provided on the movable sleeve of the direct-drive turntable body, and the opposite sides of the two second gaskets are in contact with the roller cam turntable body.

[0010] It can be seen that in the above technical solution, the stability between the direct-drive turntable body and the roller cam turntable body can be improved by the second gasket.

[0011] Furthermore, an oil inlet assembly is provided on the roller cam turntable body, and the oil inlet assembly includes a threaded piston and a first gasket.

[0012] Furthermore, the threaded piston is threadedly connected to the roller cam turntable body, the first gasket is movably sleeved on the threaded piston, and one side of the first gasket is in contact with the roller cam turntable body.

[0013] It can be seen that in the above technical solution, the threaded piston is rotated and moved away from the roller cam turntable body, and then lubricating oil is added to the roller cam turntable body. Similarly, the threaded piston is installed, and the first gasket can improve the sealing between the threaded piston and the roller cam turntable body.

[0014] Furthermore, four bottom cylinders are fixedly connected to the bottom end of the roller cam turntable body, and buffer components are provided inside the four bottom cylinders. The four buffer components include a first circular plate, a telescopic rod, a second circular plate, a buffer spring and a buffer gasket.

[0015] Furthermore, the top and bottom ends of the four first circular plates are respectively fixedly connected to the direct-drive turntable body and the four telescopic rods, the bottom ends of the four telescopic rods are respectively fixedly connected to the four second circular plates, the top ends of the four buffer gaskets are respectively fixedly connected to the four first circular plates, and the top and bottom ends of the four buffer springs are respectively fixedly connected to the four buffer gaskets and the four second circular plates.

[0016] Technical effects and advantages of the utility model:

[0017] 1. The utility model sets one of the second gaskets on the direct-drive turntable body, then passes the top of the direct-drive turntable body through the roller cam turntable body, and then puts another second gasket and the first limit plate on the top of the direct-drive turntable body, and finally rotates four fixing bolts in sequence and moves them into the direct-drive turntable body, so that the first limit plate is fixed to the direct-drive turntable body, and then the direct-drive turntable body and the roller cam turntable body are connected. Similarly, the direct-drive turntable body and the roller cam turntable body are disassembled. The composite structure is applicable to occasions with high processing accuracy requirements and relatively strong rigidity of the processing parts;

[0018] 2. In the utility model, when the four second circular plates move, the four second circular plates can drive the four telescopic rods to contract, thereby driving the four buffer springs to compress. The four buffer gaskets absorb the deformation of the four buffer gaskets to generate force, thereby playing a good buffering role, protecting the whole, and effectively extending the service life of the whole.
