Abstract

The utility model relates to a rotary workbench, in particular to a rotary workbench for a material tester. Through the implementation of the technical scheme, the flexible and reliable rotation of a rotating tray is ensured, the accurate measured position is guaranteed and thereby the accuracy of the test results is improved. The rotary workbench is formed by a workbench body, a rotating piece and a transmission piece. The workbench is square. A shaft seat is arranged in the middle of the workbench body. A rotating shaft is installed in the shaft seat. The upper end of the rotating shaft is connected with the rotating tray. A T-shaped groove is machined on the surface of the rotating tray. A T-shaped bolt is installed in the T-shaped groove and is used to fix a test sample. The rotating shaft and the rotating tray form a rotating piece. The transmission piece consists of a large sprocket, a small sprocket and a supportive chain, wherein the large sprocket is installed at the lower end of the rotating shaft and the small sprocket is installed on a cycloidal reducer. The cycloidal reducer is installed on the side of the workbench body. When in operation, through the attraction of an electromagnetic clutch, the cycloidal reducer drives the sprocket to drive the rotating tray to work. The rotary workbench is a component part of the material tester and can be widely used on large, medium and small multifunctional bending-torsion tester and testing devices of the similar type.

Description

Rotary table

Technical field

The utility model relates to Material Testing Machine, specifically is a kind of rotary table of Material Testing Machine.

Background technology

Used parts kind is many in modern electric is built, volume big, it is high to require, test item is many, and testing machine function, precision and load-bearing capacity are all had higher requirement.Especially when bending is tested, carry out mechanical property to each point on the sample circumference and detect, the worktable rotation that requires to install sample flexibly, reliable and that sample is installed is convenient.The worktable of existing testing machine is difficult to meet the demands.

The utility model content

For adapting to the needs that modern power industry is built, satisfy the requirement of all kinds of tests to the testing machine worktable, the utility model provides a kind of rotary table, realizes that the table top rotation is flexible, reliable and is convenient to loading and unloading with the rational structure pattern.

The technical scheme rotary table comprises stage body, tumbler and driving member, stage body is square, there is axle bed at the stage body middle part, rotating shaft is housed in the axle bed, the rotating shaft upper end connects rotating disc, be shaped on radially T-slot on the rotating disc, tommyhead bolt is installed in the T-slot, sample is loaded on rotating disc central authorities, fix with nut and tommyhead bolt, rotating shaft and rotating disc constitute tumbler, the rotating shaft lower end connects driving member, and described driving member comprises the hinge wheel that is loaded on the rotating shaft lower end, be contained in chain and the minor sprocket that is loaded on the cycloid speed reducer on the sprocket wheel, cycloid speed reducer is contained in the side of stage body, and have electromagnetic clutch, the adjustment bolt also is housed above the stage body.

Radially T-slot on the described rotating disc is 8, and the tommyhead bolt that is loaded in the T-slot is made of T shape piece and the screw that is screwed into T shape piece.

The beneficial effect the beneficial effects of the utility model are as follows: 1, by cycloid speed reducer control dial rotation, position of rotation is accurate, thereby measurement data is accurate; 2, can detect wide adaptability to different sizes, dissimilar test products; 3,, can accurately measure the mechanical property that goes up each point of correspondence porcelain bobbin insulator garden week owing to the accurate positioning of rotating of rotating disc energy; 4, use fixedly sample of tommyhead bolt and nut, sample is easy to loading and unloading.
