Description

A machine tool center frame and bed hydraulic locking device

technical field

The utility model relates to a locking device for a center frame of a machine tool and a bed body, in particular to a hydraulic locking device for a center frame of a machine tool and a bed body, and belongs to the field of equipment manufacturing. the

Background technique

During machine tool processing, the workpiece is generally located on the center frame, and the center frame and the bed are generally manufactured separately. In order to make the processing go smoothly, the center frame and the bed must be fixed together. Both the center frame and the machine bed are fixed manually. This method is labor-intensive, low in efficiency, poor in precision, time-consuming and labor-intensive, and may cause wear and tear on parts for a long time, resulting in long auxiliary processing time. the

Contents of the invention

The utility model provides a hydraulic locking device for the center frame and the bed of a machine tool, so as to realize the automatic fixing of the center frame and the bed. the

The utility model provides a machine tool center frame and bed hydraulic locking device, including the center frame and the bed, the center frame seat body of the center frame is provided with an oil cylinder hole, a piston body is arranged in the oil cylinder hole, and the piston body The upper and lower sides of the bed are respectively provided with oil holes, the two edges of the bed are provided with edges of a certain width, the center frame seat is located on the edge, and the width of the pressure plate is greater than the distance between the two edges of the bed and is located under the edges of the two edges of the bed. The pressure plate and the piston rod of the piston body are fixedly connected, the cylinder hole is provided with a gland above the piston body, the pressure plate and the piston body rod of the piston body are fixedly connected by bolts, and the two edges of the bed are provided with a certain width. the

This device injects oil into the two oil holes respectively so that the piston body drives the pressure plate to move up and down to realize the locking of the center frame and the bed. This device has a simple structure, is easy to implement, and has a good locking effect. the

Accompanying drawing 1 is the schematic diagram of the utility model.

Detailed ways

In order to fully explain the implementation of the present invention, specific examples of the present invention are provided. This embodiment is only an illustration and explanation of the production process of the present invention, and does not limit the scope of the present invention. the

As shown in the drawings, the hydraulic center frame 1 is used to support the parts to be processed, and is installed on the center frame body 2. The center frame 1 and the center frame body 2 are fixed together. The center frame body 2 is provided with a cylinder hole. A piston body 4 is arranged in the oil cylinder hole, an oil hole 9 and an oil hole 8 are respectively arranged above and below the piston body 4 to lead into the oil cylinder hole, the two edges of the bed 1 are provided with edges of a certain width, and the center frame seat body 2 is located along the edge. On the top, the width of the pressure plate 5 is greater than the distance between the two edges of the bed 1 and is located under the edges of the two edges of the bed 1. The pressure plate 5 is fixedly connected with the piston rod of the piston body 4, and the cylinder hole is provided with a pressure plate above the piston body 4. The cover 3 can effectively control the stroke of the piston body. The pressure plate 5 and the piston body rod of the piston body 4 are fixedly connected by bolts 7. The two edges of the bed 1 are provided with a rectangular groove with a certain width and an opening along the bottom, so that the pressure plate can move up and down. The cylinder block prevents hydraulic oil from leaking through the sealing ring. the

The working process of the utility model is:

When it needs to be locked, the hydraulic oil enters the oil through the oil hole 8 to push the piston body 4 to move upward, and the piston body 4 drives the pressure plate 5 to move together, and the pressure plate 5 locks the center frame body 2 and the machine bed 1 into one body. When loosening, the hydraulic oil enters through the oil hole 9 to push the piston body 4 to move downward, and the piston body 4 drives the pressure plate 5 to move downward together, and the pressure plate 5 pushes the center frame base body 2 and the bed 1 apart by a certain distance to realize the release .

After describing the implementation of the present utility model in detail, those skilled in the art can clearly understand that various changes and modifications can be carried out without departing from the scope and spirit of the above-mentioned patent application. Any simple modifications, equivalent changes and modifications all belong to the scope of the technical solutions of the present invention, and the present utility model is not limited to the implementations of the examples in the specification. the
