Description

Roundness measuring seat

Technical Field

The utility model belongs to the technical field of mechanical measurement detects, a roundness measuring seat is related to.

Background

After the wheel disc parts are machined, roundness measurement or detection is often required, for example, roundness detection of pulleys, flywheels and the like, and after the gears are machined, detection of various parameters of each gear tooth, such as the diameter of an addendum circle, the diameter of a dedendum circle and the like, is also required. When the parts are detected, a shaft with the diameter equal to the diameter of a hub of the part is usually manufactured, then the shaft is arranged in a hub hole of the part to be detected in a penetrating mode, then two ends of the shaft are placed on a deflection instrument to be detected, the diameters of the hub holes of the parts with different specifications are different, the shafts with the corresponding diameters need to be manufactured, and the problem that the detection is inconvenient is caused.

Disclosure of Invention

The utility model aims at having the above-mentioned problem to current technique, provided a roundness measuring seat, solved the problem that exists in the background art, improved the convenience that detects.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a roundness measuring seat, includes the bottom plate, its characterized in that, the vertical support one that is fixed with of one end of bottom plate, the vertical support two that is fixed with of the other end, the top of support one is rotated and is provided with and is conical grip slipper, be provided with the holding head that is the loudspeaker form on the support two, the rotatable setting of holding head to be connected with one and enable it to draw close or keep away from the actuating mechanism to the grip slipper.

A first rotating shaft is fixed on the conical bottom surface of the clamping seat, a bearing hole is formed in the top end of the first support, a first bearing is installed in the bearing hole, and the first rotating shaft is fixedly connected with an inner ring of the first bearing.

The driving mechanism comprises a screw and a threaded sleeve, a mounting hole is formed in the top end of the second support, one end of the threaded sleeve extends into the mounting hole and is fixed with the second support, the screw is screwed into the threaded sleeve, a sleeve is fixed to the conical top end of the clamping head, a second bearing is fixed in the sleeve, one end of the screw is fixedly connected with the inner ring of the second bearing, and a first hand wheel is fixed to the other end of the screw.

The first bearing is a deep groove ball bearing.

And the second bearing is a deep groove ball bearing.

The working principle is as follows: the hub hole sleeve of part will be surveyed is established on the grip slipper, makes the conical surface of grip slipper and surveyed part hub hole support and leans on, rotates hand wheel one, makes the terminal surface of clamping head and surveyed part support and leans on, and surveyed part is fixed between grip slipper and clamping head by the centre gripping, rotates surveyed part, can detect it, measures its circularity etc. for example through the percentage table. The clamping seat is conical, so that the clamping seat is suitable for wheel hub holes of parts with different diameters, and the detection convenience is improved.
