Description

Pneumatic clamp for machining parts with irregular positioning surfaces
Technical Field
The utility model discloses be applied to positioning fixture's technical field, in particular to irregular locating surface parts machining air jig.
Background
When a traditional processing machine tool clamps a product, the product is clamped by using calipers generally. However, when a product with an arc-shaped profile edge is processed, the clamping surface of the caliper is a plane, so that the product can swing when placed on the caliper, the product is difficult to accurately position, and the processing surface of the product in processing can not be ensured to be in a horizontal state.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art not enough, provide a convenient to use, firm reliable, be applicable to the irregular locating surface parts machining air jig of pitch arc profile product clamping.
The utility model adopts the technical proposal that: the utility model discloses a bottom plate and fixing base, the fixing base is fixed on the bottom plate, be provided with first revolving cylinder and second revolving cylinder on the bottom plate, be equipped with the arc wall on the fixing base, first revolving cylinder with the expansion end of second revolving cylinder respectively with the both ends cooperation of arc wall, the side of fixing base is provided with two spacing subassemblies at least, spacing subassembly includes the stopper and presses the post, the stopper with fixing base fixed connection, press the post along the horizontal direction with stopper fixed connection, it is a plurality of press the lower extreme of post all to be located same horizontal plane.
According to the scheme, the base plate is used for being matched with a caliper of a processing machine tool to be fixed. Through setting up the arc wall realizes spacingly with the bottom cooperation of treating the processing product, prevents that the product from swaying. Through first revolving cylinder with the cooperation of second revolving cylinder realizes compressing tightly the both ends of product respectively, ensures that the product is reliably fixed when adding man-hour. The limiting assemblies limit the processing surface of the product, and the pressing columns are matched with the limiting assemblies to limit the processing surface of the product and keep the processing surface of the product horizontal.
One preferred scheme is, first revolving cylinder's expansion end is provided with the ladder piece, the upper end of ladder piece with revolving cylinder fixed connection, the lower extreme of ladder piece is provided with first blotter.
According to the scheme, the step block is used for transmitting pressing force, and the first cushion pad is used for buffering, so that loss of a product during contact is reduced.
According to a preferable scheme, a movable frame is fixedly arranged at the movable end of the second rotary cylinder, an adjusting bolt is arranged at one end, far away from the second rotary cylinder, of the movable frame, the adjusting bolt is in threaded fit with the movable frame, and a second cushion pad is arranged at the screw head of the adjusting bolt.
According to the scheme, the adjusting bolt is arranged to adjust the pressing position, so that the angle of a part of a product with machining errors is adjusted, and the machined surface of the product can be in contact fit with all the pressing columns.
One preferred scheme is, the utility model discloses still include the spanner valve, the spanner valve is connected with outside air supply, first revolving cylinder with second revolving cylinder all through gas conduit with the spanner valve is connected.
According to the scheme, the first rotary cylinder and the second rotary cylinder are controlled in a unified mode through the hand-operated valves, so that the products can be pressed at the same time, and the products are kept horizontal during processing.
