Abstract
A rotary workbench is arranged above a base and comprises an upper working platform and a base, wherein the base is connected to the base, and a central hole is formed in the center of the base; the central hole is sleeved with an installation sleeve, and an upper thrust bearing and a lower thrust bearing are in interference fit in the installation sleeve; the bottom of the upper working platform is connected with a central column, and the central column penetrates through the upper thrust bearing and the lower thrust bearing and is connected in a central hole; positioning plates are connected to two sides of the bottom of the upper working platform, and threaded holes I are formed in the positioning plates; and a second threaded hole is uniformly formed in the periphery of the base, and positioning bolts are connected in the first threaded hole and the second threaded hole in an internal thread mode. Compared with the prior art, the utility model discloses a swivel work head, simple structure makes but work platform multi-angle rotating through the improvement, avoids the error that the secondary clamping leads to the part machining precision.
Description
Technical Field
The utility model relates to a lathe accessory technical field specifically indicates a swivel work head.
Background
Parts are generally installed on a machine tool working platform through a tool clamp, and double-side machining requirements are met when some parts are machined, so that after one side is machined, the other side is machined, and at present, a secondary clamping mode is mostly adopted for positioning, so that machined parts are prone to deviation.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to above-mentioned prior art not enough, and provide a swivel work head.
In order to solve the technical problem, the utility model discloses a technical scheme is:
a rotary workbench is arranged above a base and comprises an upper working platform and a base, wherein the base is connected to the base, and a central hole is formed in the center of the base; the central hole is sleeved with an installation sleeve, and an upper thrust bearing and a lower thrust bearing are in interference fit in the installation sleeve; the bottom of the upper working platform is connected with a central column, and the central column penetrates through the upper thrust bearing and the lower thrust bearing and is connected in a central hole; positioning plates are connected to two sides of the bottom of the upper working platform, and threaded holes I are formed in the positioning plates; and a second threaded hole is uniformly formed in the periphery of the base, and positioning bolts are connected in the first threaded hole and the second threaded hole in an internal thread mode.
Furthermore, install a plurality of bull's eyes universal ball on the base, bull's eye universal ball supports in last work platform bottom.
Furthermore, angle scale marks are correspondingly arranged on the second threaded hole.
Compared with the prior art, the utility model discloses a swivel work head, simple structure makes but work platform multi-angle rotating through the improvement, avoids the error that the secondary clamping leads to the part machining precision.
