Embodiment Construction

[0018] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0019] like Figure 1 to Figure 3 As shown, the numerically controlled rotary table of the present invention includes a machine body 10, a rotary shaft 20, a rotary encoder 30, a brake ring 40, a piston 50, a torque motor 60, and a work turntable 70 for installing workpieces. The cylinder body 11 and the rotary shaft 20 are pivotally connected to the body 10; the working turntable 70 is fixed at one end of the rotary shaft 20 and is located outside the body 10, the rotary encoder 30 is installed on the body 10, and the rotation of the rotary encoder 30 The shaft is coaxially connected with the rotary shaft 20; the piston 50 is movably installed in the cylinder body 11, and the end of the piston 50 located outside the cylinder body 11 forms a top end 51, which is connected to a top end 51 inside the body 10. A gap is formed between the side walls 12, an...

Abstract

A numerical control rotation working table comprises a machine body, a rotation shaft, a rotating encoder, a braking ring piece, a piston, a torque motor and a working rotating plate used for installing a workpiece. A cylinder is formed in the machine body. The rotation shaft is connected to the machine body in a pivoted mode. The rotating encoder is arranged on the machine body. The piston is movably arranged in the cylinder. The end, located on the outer side of the cylinder, of the piston forms an ejection end. The ejection rod is used for ejecting the braking ring piece and pressing the braking ring piece to the side wall of the machine body. According to the numerical control rotation working table, very high rotation accuracy and positioning accuracy can be output through direct drive of the torque motor and the cooperation with the high-precision encoder; in addition, linked machining and angle-fixed indexing machining can be achieved according to different machining requirements; in the linked machining process, stable machining can be conducted in the rotating process of the working rotating plate; and in the angle-fixed indexing machining process, by pressing the braking ring piece through the position and by means of the keeping torque of the torque motor, extremely high braking keeping torque can be generated so that the machining stability can be ensured.

Description

technical field [0001] The invention relates to a numerical control rotary worktable. Background technique [0002] Most of the CNC rotary tables on the market today are worm gear pairs. Due to the intermediate transmission mechanism of the worm gear turntable, the indexing accuracy of the final output cannot reach the high rotation accuracy and positioning accuracy. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a numerically controlled rotary table that can maintain high rotary precision and positioning precision all the time. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A numerically controlled rotary worktable, including a machine body, a rotary shaft, a rotary encoder, a brake ring, a piston, a torque motor, and a working turntable for installing workpieces. A cylinder is formed inside the machine body, and the rotary sh...
