Abstract

The invention relates to a machining fixture of an arc-shaped plate, which is characterized by consisting of a central shaft and a square fixture body, wherein two end faces of the central shaft are provided with central holes; the fixture body runs through the two ends of the central shaft; the periphery of the fixture body is provided with axial positioning blocks and radial positioning blocks; four corners of the fixture body are provided with screw holes which are vertical to one another; and the screw holes are spirally connected with a pressing plate through bolts. The machining fixture of the arc-shaped plate has the advantages that: the arc-shaped plate is arranged on the fixture; and four arc-shaped plates can be processed at the same time so as to ensure the concentricity of the arc-shaped plates and enhance the production efficiency.

Description

The machining fixture of arc
Technical field
The invention belongs to the machined built-up jig, relate in particular to a kind of machining fixture that can process the arc cylindrical and guarantee the arc of concentricity between each plate.
Background technology
Have its volume of a kind of arc not only greatly but also heavy on the milling train, processing is difficulty very, requires simultaneously to install between each arc of back to have the very high concentricity of precision.The arc that gets up for a long time is to be installed on the lathe floral disc to process one by one, and this kind processing method production efficiency is low, especially can not guarantee to have the high concentricity of precision between each arc.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, a kind of machining fixture of arc to be provided, can process four arcs simultaneously, both can guarantee concentricity therebetween, can enhancing productivity again.
The present invention for achieving the above object, be achieved through the following technical solutions, a kind of machining fixture of arc, it is characterized in that: the central shaft and the clamp body that is applied in its two ends that mainly are provided with centre bore by both ends of the surface, described clamp body is square, the surrounding of clamp body is respectively equipped with axial location piece and radial location piece, and clamp body is provided with orthogonal screw for four jiaos, and described screw is spirally connected by screw and pressing plate.
Described axial location piece places clamp body center line both sides, and affixed with the end face of clamp body; The radial location piece places clamp body center line both sides, and affixed with the sidewall of clamp body.
Described clamp body centre bore is square and is slidingly matched with square central shaft.
Described pressing plate is the square pressing plate, is provided with via hole on right-angle side.
Beneficial effect: arc is installed on the anchor clamps, can processes four arcs simultaneously, both can guarantee concentricity therebetween, can enhance productivity again.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the side view of clamp body;
Fig. 3 is the structural representation of pressing plate.
The specific embodiment
Below in conjunction with preferred embodiment, to details are as follows according to the specific embodiment provided by the invention:
See accompanying drawing for details, a kind of machining fixture of arc, mainly be provided with the central shaft 1 and the clamp body 2 and the pressing plate 6 that are applied in its two ends of centre bore 7 by both ends of the surface, described clamp body is square, the surrounding of clamp body is respectively equipped with axial location piece 4 and radial location piece 3, clamp body is provided with orthogonal screw 5 for four jiaos, and described screw is spirally connected by screw and pressing plate 6.Described axial location piece places clamp body center line both sides, and affixed with the end face of clamp body; The radial location piece places clamp body center line both sides, and affixed with the sidewall of clamp body.Described clamp body centre bore 8 is square and is slidingly matched with square central shaft.Described pressing plate is the square pressing plate, is provided with via hole 9 on right-angle side.
During use, arc 10 is placed on the clamp body at central shaft two ends, radial location piece on the clamp body supports the arc inwall, axial location piece on the clamp body withstands the end face of arc, precasts the ladder platform in the arc two ends, and pressing plate is pressed on the ladder platform, by screw that pressing plate and clamp body is fastening, push down arc, whole frock is hung on the lathe, by dial and withstand centre bore and can process by crane.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
