SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a technical problem provides a base class product multistation milling fixture, solves the inconvenient problem that just adds the machining dimension precision is not high of current anchor clamps loading and unloading.
In order to solve the above problem, the utility model discloses the technical scheme who adopts is: the utility model provides a base class product multistation milling fixture, includes bottom plate, backup plate, briquetting, the bottom plate is equipped with spacing hole along the central line symmetry, and the backup plate can be dismantled with the bottom plate and be connected, and the briquetting is located the backup plate top, and the briquetting can be dismantled with the backup plate and be connected.
The technical principle of the technical scheme is as follows: when the product needs to be processed, the product is placed on the bottom plate and is positioned through the limiting hole, and the pressing block is screwed down, so that the pressing block compresses the product, and the product is fixed on the bottom plate. And the machining of base products is realized by adjusting the angle of the bottom plate.
The beneficial effect that this scheme produced is: 1. according to the design characteristics of the product, the arc on the bottom surface of the product is used as positioning, and the clamp is designed to be square clamping by using the clamping characteristics of the numerical control milling machine on the clamp aiming at the processing position of the product, so that the clamping stability of the clamp is effectively controlled, and the processing precision of the product is ensured.
2. The clamp has the advantages of simple design structure, stability, safety, reliability, low manufacturing cost, easy manufacture and repeated use; and the operation is convenient, fast and strong. Can be popularized and applied to various machining fields.
Furthermore, still include the position sleeve, still be equipped with the locating hole on the backup plate, the position sleeve can be dismantled with the backup plate and be connected. Transversely insert the backup plate through the position sleeve on, vertically carry on spacingly to the product for the product location is more accurate, guarantees product machining precision.
Further, the briquetting is L shape. The L-shaped pressing block is convenient for pressing the product downwards and is easy to process.
Further, the bottom plate is arc-shaped. The arc-shaped bottom plate is more attached to the product characteristics, so that the clamping is convenient, and the processing efficiency is improved.
Furthermore, the upper surface of the bottom plate consists of two bottom plate inclined planes, and the included angle between the two bottom plate inclined planes is 180-135 degrees. The upper surface is made into an inclined plane, so that the circular hole can be processed by a numerical control milling machine more easily.
Furthermore, the bottom of the backup plate is composed of two backup plate slopes, and the included angle between the two backup plate slopes is 180-135 degrees. The lower surface of the backup plate is processed into an inclined plane, so that the backup plate is convenient to be matched with the bottom plate and is more convenient to connect.
