Abstract
The utility model discloses a fixture for machining of pump impellers, which is in a cylindrical structure formed by three joined portions with same structures. The side wall of each portion is used for fixing a blade of a pump impeller, a positioning column is arranged in each portion, one end of each positioning column is fixedly connected with the bottom of each portion, the other end face of each positioning column is provided with an arc face fitting the surface of the pump impeller, and the arc face is used for positioning the surface of the pump impeller. An elongated boss is arranged on the outer side of the bottom of each portion, and a mounting hole is arranged on each elongated boss. By means of the fixture for positioning a slope of the pump impeller, and the outer periphery of the pump impeller, namely the outer side of each blade is clamped by the side walls, coaxial mounting is guaranteed to enable a workpiece to be machined to be within the tolerance limits, and repair rate and rejection rate in machining are decreased from 10% to 1%. The fixture for machining of pump impellers has the extraordinary advantages that the fixture is easy in clamping and requires little time for mounting and demounting, and thereby operating efficiency is improved.
Description
Technical field
The utility model relates to a kind of anchor clamps, specifically is a kind of impeller of pump fixture for processing.
Background technology
Traditional impeller of pump fixture for processing is difficult for clamping, and loading and unloading, time of being spent of adjustment are long, generally clamp once needs 20 minutes, so obviously reduced operating efficiency; In addition; The not enough balance of the impeller of pump that processes, beat big, can reach 1～2mm with the coaxiality deviation of external diameter, so the impeller of pump that utilizes traditional anchor clamps to process; Repair rate and percent defective can reach 10%; So improved the manufacturing cost of product greatly, not only wasted raw material, but also wasted time and energy.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model purpose is to provide a kind of to be convenient to load and unload, high efficiency and the impeller of pump fixture for processing that can improve the quality of products.
To achieve these goals, the technical scheme of the utility model employing is:
The impeller of pump fixture for processing; It is the round barrel shape structure that is spliced by three identical parts of structure; The sidewall of every part all is provided with reference column in order to the blade of fixed pump impeller in every part, an end of reference column is fixedly connected with the bottom surface of every part; The other end is provided with the arc surface that the surface with impeller of pump adapts, and the arc surface of this end is in order to the surface of location impeller of pump.
The central part at the bucket end that said three parts are spliced is established through hole.
The outside, bottom surface of said every part is provided with the strip boss.
The beneficial effect of the utility model: owing to adopted the version of above-mentioned anchor clamps; Inclined-plane to impeller of pump positions; And clamp the external diameter of impeller of pump with sidewall, i.e. the outer side edges of blade, thus coaxial installation not only guaranteed; Make processed workpiece in the margin of tolerance, the repair rate, percent defective that makes processing drops to 1% by original 10%; The degree of balance of impeller of pump has obtained effective raising, has improved the quality of product; The maximum characteristics of the utility model are to clamp easily, and it is few to load and unload the used time, thereby has improved operating efficiency.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to specify.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the cutaway view along the A--A line shown in Figure 1;
Fig. 3 is the vertical view of impeller of pump among Fig. 2.
Among the figure: 1, part; 2, sidewall; 3, the blade of impeller of pump; 4, reference column; 5, bottom surface; 6, the surface of impeller of pump; 7, through hole; 8, strip boss.
The specific embodiment
Like Fig. 1,2, shown in 3; The impeller of pump fixture for processing, it is the round barrel shape structure that is spliced by three identical parts of structure, the sidewall 2 of every part 1 is in order to the blade 3 of fixed pump impeller; All be provided with reference column 4 in every part 1; One end of reference column 4 is fixedly connected with the bottom surface 5 of every part, and the other end is provided with the arc surface that the surface 6 with impeller of pump adapts, and the arc surface of this end is in order to the surface of location impeller of pump.
The central part at the bucket end that said three parts are spliced is established through hole 7.
5 outsides, bottom surface of said every part are provided with strip boss 8.
The above is the preferred implementation of the utility model, can not limit the interest field of the utility model certainly with this.Should be pointed out that for those skilled in the art, the technical scheme of the utility model is made amendment or is equal to replacement, do not break away from the protection domain of the utility model.
