Description

Technical Field

[0001] The utility model relates to the technical field of mechanical turntables, in particular to a turntable with a variable tilt angle. Background Art

[0002] The rotary table is an ideal accessory for all kinds of CNC milling machines and machining centers. It is installed horizontally on the work surface of the host machine. When working, it uses the control system of the host machine or a specially matched control system to complete the indexing rotary motion of various processing coordinated with the host machine. For some small and medium-sized parts, multiple processes can be processed in the same clamping, and the productivity of the machine tool is improved. Application field: The rotary table is generally suitable for mechanical manufacturing in the automobile, motorcycle, instrument hardware, pump and valve industries.

[0003] The existing turntable has a relatively simple function, which is only to adjust the workpiece to rotate in different directions. When grinding the workpiece, in order to facilitate the grinding work in multiple angles, corresponding angle adjustments are required, which is a requirement that cannot be met by the existing mechanism, and the trivial debris generated during the grinding process cannot be effectively blocked and removed, which is not conducive to the beautification and improvement of the processing environment. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0028] Reference Manual Attached Figure 1-Figure 6 As shown, a rotary table with variable tilt angle includes:

[0029] Base 1; waterproof shield 2, which is installed at the bottom of the base 1 and welded and fixed by bending steel plates, and a drainage groove 3 is opened at the center of the waterproof shield 2; a shifting mechanism 4, which includes two groups of screw lifts 5 on the base 1, and one end of the transmission shaft 6 on the screw lift 5 extends to the shifting motor 7. As the shifting motor 7 is started, the screw lift 5 drives the support platform 8 to rotate around the rotating axis 9 as the center; a rotating mechanism 10, which includes a rotating motor 11 placed on the support platform 8, and one end of the rotating motor 11 extends to the first rotating tooth 12. The outer wall of the first rotating tooth 12 is meshed with a second rotating tooth fixed on the turntable 13. As the rotating motor 11 is started, the turntable 13 rotates around itself.

[0030] Specifically, the working principle of the screw lift 5 is mainly based on the spiral transmission between the screw shaft and the nut. Under the action of the variable position motor 7, the screw shaft rotates, and the threads on the nut interact with each other, so that the nut moves axially. This movement can be up or down, depending on the direction of rotation of the screw shaft. In the ball screw design, the balls are placed in the raceway between the screw shaft and the nut, so that when the screw shaft rotates, the balls can roll in the raceway, reducing friction and improving efficiency.

[0031] Specifically, a lead screw 14 is movably installed around the turntable 13, one end of the lead screw 14 is provided with a socket and a handle 15 adapted thereto is limitedly connected thereto, and a bevel gear 16 is installed at the other end, and adjacent bevel gears 16 are meshed with each other in a four-corner transmission, and a slider 18 fixed on the claw 17 is spirally driven on the lead screw 14. The slider 18 is connected with a strip groove along the length direction of the turntable 13, and as the handle 15 rotates, the lead screws 14 around drive the claws 17 to clamp or separate each other at the same time.

[0032] The rotary mechanism 10 rotates the handle 15 to rotate the lead screw 14, and the lead screw 14 can drive the bevel gear 16 to move together. In this way, through the reversing transmission principle of the bevel gear 16, the lead screws 14 on all sides can rotate together, and then with the help of the spiral transmission, the claws 17 on the sliders 18 on all sides can be clamped or separated with each other, and the synchronization performance is strong, which can better realize the synchronous clamping and fixing work, thereby facilitating the subsequent cleaning and grinding of the workpiece.

[0033] Specifically, the outer wall of the rotating shaft 9 is provided with a rotating groove connected to the extended section of the support platform 8, and a supporting cylinder 19 connected to the base 1 is fixedly installed at the bottom end of the support platform 8, and the bottom of the piston rod on the supporting cylinder 19 is connected to an annular pad 20. The supporting cylinder 19 on the support platform 8 can play an auxiliary fixing role for the support platform 8 and provide corresponding supporting force. Moreover, the setting of the annular pad 20 can expand the force-bearing area, thereby preventing the phenomenon of force overload. A drainage pipe 21 extending to the outside is installed on the waterproof shield 2.

[0034] The waterproof shield 2 is mainly used to collect the wastewater after grinding and prevent the cutting fluid from splashing during grinding and causing pollution to the factory area. Therefore, the waterproof shield 2 is very deep and the bottom is drained through the drainage trough 3 bent by the steel plate to concentrate the sewage and will not cause sewage accumulation. In addition, in conjunction with the drainage pipe 21, the sewage discharge effect can be further improved to ensure that the device can be used normally.
