Detailed Description
The technical solution of the present application is further specifically described below by way of examples and with reference to the accompanying drawings.
Referring to fig. 1 to 3, there are shown schematic structural views of the vacuum adsorption positioning fixture of the present application. The utility model provides a vacuum adsorption positioning jig includes 1, bottom plate 2, reference column 3, vacuum pump, switch 4, end fixed plate 5 and support column 6 isotructures.
Referring to fig. 3, the upper surface of the upper fixing plate 1 is provided with a positioning area and four positioning holes 15 formed on two adjacent sides of the positioning area. The positioning area is used for adsorbing and fixing the processed product. As shown in FIG. 3, the positioning region is provided with uniformly distributed air suction grooves 11, the air suction grooves 11 are distributed crosswise, and each intersection is provided with a vent 12. And a ring sealing groove 13 is formed along the peripheral wall of the outermost air suction groove, and the upper sealing groove 13 is not communicated with the air suction groove 11. And a rubber strip is filled in the upper sealing groove 13 and is used for sealing with a processed product in a vacuum state to prevent air leakage. Support surfaces 14 are respectively arranged in the middle gaps of the intersected air suction grooves 11, and the support surfaces 14 are used for supporting the processed product, so that the upper surface of the support surface is not higher than that of the upper fixing plate 1.
As shown in fig. 1 and 2, the lower fixing plate 2 is fixed below the upper fixing plate 1 by a fixing member such as a bolt, and the combination of the upper and lower fixing plates 1 and 2 is not limited to the bolt locking manner. The lower fixing plate 2 is provided with a positioning column 3, and the positioning column 3 of the present embodiment is a telescopic structure driven by a cylinder 7, but not limited thereto. When the positioning column 3 is in a retracted state, it can be retracted into the positioning hole 15 of the upper fixing plate 1. When the vacuum pump is started, the positioning column 3 is driven by the cylinder to be retracted into the positioning hole 15; when the vacuum pump is turned off, the positioning column 3 is driven by the vacuum pump to rise and exceed the upper fixing plate 1. The positioning column 3 is used for positioning the position of the product.
Meanwhile, the upper surface of the lower fixing plate 2 is depressed downward to form a vacuum groove 21. The size range (i.e., length and width) of the vacuum groove 21 is larger than the size (i.e., length and width) of the positioning region of the upper fixing plate 1, i.e., the positioning region is entirely located within the vacuum groove 21 after the upper fixing plate and the lower fixing plate are mounted. The vacuum vessel 21 communicates with each of the vent holes 12. The vacuum tank 21 is in communication with a vacuum pump. The vacuum pump is electrically connected with a switch 4, and the opening and closing of the vacuum pump can be directly controlled through the switch 4. When the vacuum pump is turned on, the air in the vacuum chamber 21 is evacuated, and meanwhile, since the vacuum chamber 21 is communicated with the vent hole 12, the vent hole 21 forms a uniform adsorption force along the suction chamber 11, so that the processed product can be stably adsorbed without shaking. In order to further ensure the sealing performance of the vacuum chamber 21, as shown in fig. 2, a circle of lower sealing groove 22 is formed along the outer circumference of the vacuum chamber 21, and a rubber strip is filled in the lower sealing groove 22 to ensure the airtightness of the upper fixing plate 1 and the lower fixing plate 2 and to ensure the stable adsorption force of the vacuum chamber 21. Similarly, the lower seal groove 22 does not communicate with the vacuum groove 21.
As shown in fig. 1, the upper fixing plate 1 and the lower fixing plate 2 are supported by four supporting pillars 6 and then connected to the bottom fixing plate 5. The bottom fixing plate 5 is provided with a fixing hole for connecting to a work table by a fixing member such as a bolt or a flange. Switch 4 is fixed between bottom plate 2 and bottom plate 5 through switch fixed plate 8, towards the one side that the operator stood, and the vacuum pump is opened and close in the fast operation of being convenient for.
According to the air suction device, the air suction grooves 11 which are crossed transversely and vertically are additionally arranged on the upper fixing plate 1, so that the suction force of the whole positioning area is stable and balanced, the problem of poor suction force caused by the problem of a single air vent is solved, a machined workpiece can be kept to be stably and flatly sucked, and an additional pressurizing plate is not needed for fixing; meanwhile, the operation process is simplified, and the working efficiency is improved.
The above-described embodiments are merely illustrative of the present application and are not intended to limit the scope of the present application. All equivalent changes and modifications of the present application made by those skilled in the art are intended to be covered by the appended claims.
