Detailed Description

The present invention will be further described with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

Referring to fig. 1-4, a horizontal machining center rotary worktable comprises a base 1, supporting plates 2 are arranged at two ends of the base 1, a worktable 4 is arranged between the two supporting plates 2 through a rotating shaft 3, the rotating shaft 3 penetrates through one of the supporting plates 2, a driven gear 5 is arranged on the rotating shaft 3, the driven gear 5 is in meshing transmission connection with a rotating mechanism 6, and a driving mechanism 7 is in transmission connection with the lower part of the rotating mechanism 6.

In this embodiment, the rotating mechanism 6 includes the rack 61 located on both sides of the driven gear 5 and engaged with the driven gear 5, the lower end of the driven gear 5 is further provided with the driving gear 62, the driving gear 62 is fixedly arranged on the supporting plate 2 by the arrangement of the pin shaft 63, and the driving gear 62 is in transmission connection with the driving mechanism 7. The rotation of the driving gear 62 drives the gear 61 to move up and down, that is, the driven gear 5 rotates forward and backward, so that the rotating shaft 3 drives the workbench 4 to rotate; the rack 61 and the support plate 2 can be fixed by arranging a slide rail, and the up-and-down movement of the rack 61 is not hindered.

In this embodiment, the driving mechanism 7 includes a base 71 disposed on the supporting plate, a driving rack 72 is disposed on the base 71 in a transverse direction, the driving rack 72 is in meshing transmission with the driving gear 62, a sleeve 73 with a hollow structure is disposed at a lower end of the driving rack 72, a partition 731 is disposed in the middle of the sleeve 73, two ends of the partition are open, a limit ring 732 is disposed at the opening, a back of the sleeve 73 is movably connected to the base 71 by a slide rail 74, a push rod 75 is disposed in the sleeve 73, a snap ring 751 is disposed on an inner side of the push rod 75, a connecting member 76 is disposed on an outer side of the push rod 75, the connecting member 76 is fixedly connected to the hydraulic cylinder 77.
