Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Please refer to Fig. 1, which is a schematic diagram of the utility model.

An automatic fixture comprises a fixture bottom plate 1, and a guide groove 2 is arranged on the fixture bottom plate 1, wherein the cross-sectional shape of the guide groove 2 is trapezoidal. The inside of the guide groove 2 is provided with a symmetrically arranged slide block 3, and the slide block 3 is connected with a telescopic device 4 arranged on one side of the clamp bottom plate 1, wherein the telescopic device 4 is an air cylinder, which can drive the slide block 3 reciprocating movement. Each of the sliders 3 is provided with a main telescopic rod 5 and a support plate 6, the upper end of the main telescopic rod 5 is connected to one end of the pressing plate 7, and the supporting plate 6 is hingedly connected to the pressing plate 7. The end of the pressing plate 7 is provided with a fixed plate 8, wherein the fixed plate 8 is fixedly connected with the pressing plate 7, so that the up and down movement of the main telescopic rod 5 drives the fixed plate 8 to move up and down to realize the processing of parts. Fixed, easy to process.

The fixture base plate 1 is provided with at least one secondary telescopic rod 9, wherein the main telescopic rod 5 and the secondary telescopic rod 9 are cylinders or helical screw assemblies, and the upper end of the secondary telescopic rod 9 is provided with a top plate 10, such that the top plate 10 can support the processing parts. The utility model can quickly fix the processing parts, has wide application range and simple structure, so it works stably and reliably.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
