Description

Fixture device for mandrel boring

technical field

The utility model relates to a clamp device, in particular to a clamp device for mandrel boring.

Background technique

A fixture is a device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position for construction or inspection. In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be called a fixture. Fixtures are usually composed of positioning elements, clamping devices, tool setting guide elements, indexing devices, connecting elements, and clamp bodies. Mandrel boring must be done using a special jig.

Utility model content

The purpose of the utility model is to provide a fixture device for mandrel boring, which has a reasonable structural design, uses a cylinder to press the mandrel tightly, and is fastened firmly to ensure the positional accuracy of the mandrel processing.

The technical scheme of the utility model is as follows:

The fixture device for mandrel boring includes a lower template, a column is fixed on the lower template, an upper template is fixed on the upper end of the column, a mandrel is fixed on one end of the upper template, and a cylinder is fixed on the other end, and the piston rod of the cylinder is connected with a The top tie rod is fixed with a horizontal strip bar, the upper template is fixed with a support bar, the top of the support bar is hinged with the bar bar, and the front end of the bar bar is fixed with a briquetting block directly above the mandrel.

A strip-shaped slideway is opened on the strip-shaped rod, and a pin shaft located in the strip-shaped slideway is installed on the top of the support rod.

The cylinder of the utility model pushes the top pull rod to move upwards, and at the same time, the pressing block at the other end of the strip rod is pressed downwards to the upper end of the mandrel. positional accuracy.
