Abstract

The utility model discloses a blade arc grinding apparatus. Two lateral faces of the clamp body are respectively provided with a grinder center hole on a same central line, and grooves in which finished blades can be placed are arranged on the clamp body, and a cover plate on which a locking bolt is provided for clamping the blade is connected above the grooves on the clamp body by screws, and an operating handle is connected with the clamp body by a screw bolt. The utility model has the advantages of simple structure, fewer investments, low cost of processing and easy, convenient operation. When the utility model is used, first the blade is clamped in the groove of the clamp body, and the clamp body is arranged between the excircle grinder headstock and the center of the workbench, and the grinding work is started. During grinding operation, the operating of the handle by hand makes the clamp body do repeated swinging taking the central line of the center as rotation center, and the roughness and profile tolerance of arc surface of the ground blades completely reach the requirements.

Description

The blade arc grinding device

Technical field:

The utility model relates to a kind of blade arc grinding device that is used for processing rotor formula compressor blade, belongs to compressor blade machining tool technical field.

Background technology:

Rotor-type compressor is the heart of domestic air conditioning, blade (1) is the core part of compressor, because compressor requires low noise, energy-saving and environmental protection, high-efficiency long-life, therefore require blade (1) to have high rigidity, a very high row position tolerance, dimensional accuracy and surface roughness.This has just caused the difficulty of blade processing, wherein the requirement of most critical is the perpendicularity 2.5 μ ms of the circular arc (R) of blade (1) to side benchmark (A), all adopt when at present, processing the circular arc (R) of blade (1) in the prior art earlier on surface grinding machine form grinding (R) face use again double-ended grinding machine with the big plane (B) of blade (1) and (R) the face location method of processing the grinding side guarantee (R) perpendicularity 2.5 μ m to side benchmark (A).Because existing this process technology need be invested special purpose machine tool equipment, therefore exist the shortcoming that investment is high, processing cost is high; In addition, prior art also exists the processing technology complexity, requires operating personnel to have the shortcoming of higher operant level.

Summary of the invention:

The purpose of this utility model is: provide a kind of simple in structure, small investment, processing cost blade arc grinding device low, easy and convenient to handle, to overcome the deficiencies in the prior art.

The utility model is to constitute like this: it is being respectively equipped with a grinding machine center hole (14) on same center line on the two sides of clamp body (2), and on clamp body (2), also be provided with the groove (15) that to lay processed blade (1), top at clamp body (2) upper groove (15) is connected with a cover plate (5) by screw (9), is provided with the clamping screw (11) that is used to clamp blade (1) on cover plate (5); Upward be connected with an operating grip (6) at clamp body (2) by bolt (7); On a side of the groove (15) of clamp body (2), be provided with two alignment pins (12), on another side of groove (15), be connected with a spring leaf (3), and be provided with one in the bottom of groove (15) and be connected positioning strip (4) on the clamp body (2) by screw (8) by bearing pin (13); Be equipped with at clamp body (2) on the side of a side of spring leaf (3) lock-screw (10) also is housed.

Owing to adopted technique scheme, the utility model compared with prior art the utlity model has simple in structure, small investment, processing cost advantage low, easy and convenient to handle.When using the utility model, earlier blade (1) is packed in the groove (15) of clamp body (2), and locate with alignment pin (12), its height dimension is controlled by positioning strip (4), hold out against screw (10) drive spring leaf (3) earlier and compress blade (1), after tightening clamping screw (11) again, clamp body (2) is contained in the cylindrical grinder headstock and workbench top (16) between can begin grinding work, during grinding work, workbench is motionless, with manual swinging operation handle (6), and the emery wheel (17) that makes grinding machine is cut the profile of blade (1), making clamp body (2) by operating grip (6) is that center of rotation is done swing repeatedly with the center line of top (1 6), can make circular arc (R) surface roughness of the blade (1) that grinding goes out, profile tolerance reaches requirement fully.

Accompanying drawing 1 is the structural representation of the blade processed by the utility model;

Accompanying drawing 2 is that the I of accompanying drawing 1 is to schematic diagram;

Accompanying drawing 3 is a structural representation of the present utility model;

Accompanying drawing 4 is the C-C generalized section of accompanying drawing 3;

Accompanying drawing 5 adds the schematic diagram in man-hour on grinding machine for the utility model.

The specific embodiment:

Embodiment of the present utility model: during making, earlier producing a grinding machine center hole (14) on same center line on the two sides of clamp body (2) respectively, on clamp body (2), produce the groove (15) that to lay processed blade (1) then, and connect a cover plate (5) by screw (9) in the top of clamp body (2) upper groove (15), go up at cover plate (5) and install one and be used to clamp blade clamping screw (1) and that have handle (11); Go up by the fixedly connected operating grip of bolt (7) (6) at clamp body (2); In order to locate conveniently, two alignment pins (12) that adopt carbide alloy to make are installed on a side of the groove (15) of clamp body (2), and on another side of groove (15), connect a spring leaf (3) by bearing pin (13), establish in the bottom of groove (15) then by screw (a 8) positioning strip of connection (4) on clamp body (2); More reliable in order to locate, lock-screw that can promote spring leaf (3) can be installed on clamp body (2) are equipped with the side of a side of spring leaf (3) (10).
