The technical scheme of the utility model is further explained by combining the attached drawings as follows:

fig. 1 is a sectional view of a liftable turntable structure according to the present invention;

fig. 2 is a cross-sectional view of the middle positioning mechanism of the present invention.

Wherein: 1. a servo motor; 2. a coupling; 3. a piston rod; 4. a cylinder body; 5. a work table; 6. a rotating shaft; 7. a turntable; 8. a radial bearing; 9. a positioning mechanism; 91. a positioning sleeve; 92. positioning holes; 93. a fixing plate; 94. positioning the oil cylinder; 10. a guide bar; 11. a slide plate; 12. and a through hole.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The attached figures 1-2 show a liftable turntable structure of the present invention, which comprises a turntable 7 horizontally disposed above a worktable 5, a cylinder body 4 vertically disposed at the bottom of the worktable 5, a piston rod 3 vertically disposed in the cylinder body 4 and having an upper end passing through the worktable 5, a through hole 12 coaxially disposed at the bottom of the piston rod 3, a rotating shaft 6 vertically disposed in the through hole 12 and having an upper end fixedly connected to the middle of the turntable 7, and a servo motor 1 disposed at the lower end of the piston rod 3 and having an output end connected to the rotating shaft 6 through a coupling 2; the upper end of the piston rod 3 is provided with a positioning mechanism 9 which can accurately position the turntable 7; when in work: hydraulic oil is injected into the cylinder body 4 under the control of an external controller, and the piston rod 3 can be driven to move up and down, so that the rotary table 7, the rotating shaft 6 and the servo motor 1 are driven to synchronously move up and down to realize lifting; the servo motor 1 can drive the rotating shaft 6 to drive the rotating disc 7 to rotate, so that rotation is realized.

Further, the positioning mechanism 9 includes a positioning sleeve 91 sleeved on the upper end of the piston rod 3 and fixedly connected with the bottom of the turntable 7, a plurality of positioning holes 92 arranged on the surface of the positioning sleeve 91 and corresponding to the stations, a fixing plate 93 fixed on the piston rod 3 and located below the positioning sleeve 91, and a positioning oil cylinder 94 horizontally arranged on the fixing plate 93 and having an output end capable of extending into the positioning holes 92; during operation, when the rotating shaft 6 drives the rotating disc 7 to rotate, the positioning sleeve 91 can also rotate along with the rotating shaft, and when the rotating shaft moves to a station and stops, the positioning oil cylinder 94 drives the output end to extend into the positioning hole 92, so that accurate positioning is realized.

Further, the bottom of the workbench 5 is also vertically provided with four guide rods 10 which are uniformly arranged by taking the cylinder body 4 as a center, and a sliding plate 11 which is sleeved at the lower end of the piston rod 3 and can slide up and down along the four guide rods 10; the sliding plate 11 is fixedly connected with the servo motor 1; by adding the guide rod 10, the turntable 7 is more stable in the lifting process.

Further, a gap is formed between the upper end face of the piston rod 3 and the bottom face of the rotary table 7, the gap is 2mm, abrasion between the upper end face of the piston rod 3 and the bottom face of the rotary table 7 is avoided, and the service life is shortened.
