Abstract
The utility model discloses a fixture for processing an inner hole of an elliptical pump body. The fixture comprises an upper semicircular fixture body, a lower semicircular fixture body and a connecting plate, wherein the lower semicircular fixture body is arranged on the upper part of the connecting plate, the upper semicircular fixture body is movably connected with the lower semicircular fixture body, the outer edge of the upper semicircular fixture body is provided with reinforcing ribs, the two side edges of the upper semicircular fixture body are respectively provided with an upper through hole, the outer edge of the lower semicircular fixture body is provided with reinforcing rib plates, the two side edges of the lower semicircular fixture body are respectively provided with a lower through hole corresponding to the upper through hole, and the lower part of the connecting part is provided with T-shaped blocks. When the inner hole of the elliptical pump body of a water ring vacuum pump is processed by the fixture, one-time clamping, positioning and correction is required, and the machined trace is avoided. The fixture has the advantages that the structure is simple, the convenience in use is realized, and the fixture is suitable for processing the inner hole of the elliptical pump body of the water ring vacuum pump, and is also suitable for processing other elliptical inner holes.
Description
Technical field
The utility model relates to a kind of anchor clamps, is specifically related to a kind of frock clamp of processing oval pump housing endoporus.
Background technology
Existing method to the oval pump housing endoporus processing of water ring vacuum pump is to adopt lathe, and the pump housing is contained on the lathe chuck by tool locating, begins processing after the correction, after processing, need to adjust again clamping, location and correction after the off-centre by frock, processes again.Elliptical inner with this conventional method processing leaves machined trace between twice working position, and needs twice clamping, location and correction, can not time processing put in place, has both affected product quality, can not improve working (machining) efficiency again.
Summary of the invention
The purpose of this utility model is to overcome the prior art deficiency, and a kind of employing boring machine is provided, and hole processing clamp in the oval pump housing that puts in place of time processing.
The purpose of this utility model is achieved in that a kind of anchor clamps of processing oval pump housing endoporus, comprise upper semi-circle clamp body, lower half circle clamp body and connecting plate, it is characterized in that: the lower half circle clamp body is arranged on the top of connecting plate, and upper semi-circle clamp body and lower half circle clamp body are flexibly connected.
The outer rim of described upper semi-circle clamp body is provided with at least one reinforcement, and dual-side is provided with at least two upper through holes, and the outer rim of described lower half circle clamp body is provided with at least two and strengthens gusset, and dual-side is provided with the lower through-hole corresponding with upper through hole.
The bottom of described connecting plate is provided with T-shaped.
Compared with prior art, adopt the utility model to process oval pump housing endoporus, only need clamped one time, location and correction, and do not have machined trace, not only improved product quality, improved working (machining) efficiency, and effectively reduced processing cost.

Among the figure, upper semi-circle clamp body 1, reinforcement 11, upper through hole 12, suspension ring screw 13, lower half circle clamp body 2, strengthen gusset 21, lower through-hole 22, connecting plate 3, T-shaped 31.
The specific embodiment
The utility model is described in further detail by reference to the accompanying drawings for following embodiment.
See figure: a kind of anchor clamps of processing oval pump housing endoporus of the utility model comprise upper semi-circle clamp body 1, lower half circle clamp body 2 and connecting plate 3.Lower half circle clamp body 2 is fixedly installed on the top of connecting plate 3, and upper semi-circle clamp body 1 is flexibly connected by screw bolt and nut with lower half circle clamp body 2.
Evenly be provided with at least one reinforcement 11 in upper semi-circle clamp body 1 outer rim, the present embodiment is provided with two strong muscle 11.The outer rim of strong muscle 11 and upper semi-circle clamp body 1 can be fixedly installed and be integrated, and also can be movably arranged on the outer rim of upper semi-circle clamp body 1.Be provided with through hole 12 at least two at the straight position of upper semi-circle clamp body 1 dual-side, the present embodiment is provided with three upper through holes 12.Outer rim middle part at upper semi-circle clamp body 1 is provided with suspension ring screw 13.
Outer rim at lower half circle clamp body 2 is provided with at least two reinforcement gussets 21, and the present embodiment is provided with two strong gussets 21.Strengthen the top inner circle of gusset 21 and agree with mutually with the bottom outer rim of lower half circle clamp body 2, and be connected to one, strengthen the bottom of gusset 21 and the top of connecting plate 3 and connect as one.Be provided with at the straight position of lower half circle clamp body 2 dual-sides and upper through hole 12 lower through-hole 22 one to one.
Be provided with at least one T-shaped 31 in the bottom of connecting plate 3, the present embodiment is provided with three T-shaped 31.T-shaped 31 with boring table on T-shaped groove agree with mutually.
During use, the T-shaped 31 T-shaped groove that inserts on the boring table that will arrange with connecting plate 3 bottoms that lower half circle clamp body 2 connects as one first, again the oval pump housing is placed the inner circle of lower half circle clamp body 2, cover upper semi-circle clamp body 1, the upper through hole 12 that the straight position of upper semi-circle clamp body 1 dual-side is arranged is corresponding one by one with the lower through-hole 22 that the straight position of lower half circle clamp body 2 dual-sides arranges, bolt passes through hole 12 and lower through-hole 22, screws and can process with nut after location, correction.
The utility model is simple in structure, and is easy to use, is not only applicable to the processing of oval pump housing endoporus, also is applicable to the processing of other elliptical inners.
