technical field

The utility model relates to the fields of boring and milling machine tools, in particular to a horizontal rotary fixture.

Background technique

With the development of my country's modern industrial technology, higher and higher requirements are put forward for the technical performance and economic indicators of mechanical transmission devices. Ordinary fixtures can no longer meet the needs of large-scale and efficient production in modern industry, and the development of new fixtures is an important step in the machinery industry. one of the important subjects. The horizontal rotary fixture designed in this utility model can clamp various rectangular and irregular workpieces by adjusting the positions of the four claws. At the same time, it can also be installed on boring machines, milling machines, drilling machines and slotting machines as important accessories to process holes, grooves and slopes with indexing requirements. When turning the device during processing, it can process arc surfaces and arc grooves. What ordinary fixtures do not have. On the basis of meeting the precision requirements, the device is easier to operate, compact in structure, and has a wider range of applications. The design of this device can meet the requirements of the market and customers, and will be widely recognized.

Contents of the invention

The utility model belongs to a technical innovation, which provides a horizontal rotary fixture with compact structure, simple operation and meeting specific processing requirements.

The purpose of this utility model is achieved in this way: a horizontal rotary fixture, which includes a base, is characterized in that: the base is provided with a horizontal rotary device, the leftmost end of the horizontal rotary device is connected to the hand wheel by the handle, and the hand wheel is connected to the hand wheel. The worm shaft is connected by a key. There is a locking sleeve at the left end of the hand wheel, and the locking sleeve is locked with the worm shaft. There is a bush at the right end of the hand wheel, which is connected with the scale wheel. The worm shaft is surrounded by the sleeve, and there is a Worm, the worm meshes with the worm gear, there is a shaft at the lower end of the worm gear, and the locking device is connected to the shaft to fix the worm gear; the locking device is linked by a locking handle and a locking rod through a pin, and the locking rod and the locking rod The ring is connected and locked by a threaded pair. There are four threaded holes in the turbine as a whole, and four bolts are inserted into the four threaded holes. Through the bolts, the turbine is connected with the four-jaw chuck body, and there are four threaded holes in the chuck body. , and four lead screws, there are four claws on the lead screw.

The body part of the four-jaw chuck has scale lines.

The four bolts described are fully threaded bolts.

Described leading screw is trapezoidal leading screw.

Beneficial effects of the utility model: when the utility model is in use, the hand wheel drives the worm to rotate, and the worm is engaged with the turbine, thereby realizing the conversion of vertical rotary motion into horizontal rotary motion. The machine can process arc surfaces and arc grooves; there is a scale line on the chuck body, which is used in conjunction with the dial on the airport, and can be used to process holes, grooves and slopes with graduation requirements. At the same time, the chuck fixture can clamp various rectangular and irregular workpieces by adjusting the position of the four jaws, and each jaw can move independently; by rotating the locking lever, the locking ring and the turbine shaft are clamped to fix the chuck The body can carry out necessary processing; the device has a compact and reasonable structure, simple operation and strong practicability, and is an indispensable main auxiliary machine for working machines such as boring and milling machines. It can be used to support the workpiece and make it do linear or rotary adjustment and feed movement to expand the performance of the machine tool and shorten the auxiliary time. It is widely used in mechanical processing in machinery, energy and other industries.
