Technical field
The present invention relates to field of machining, specifically a kind of brake shoe iron arc surface drilling equipment.
Background technology
Drum brake is widely used in all kinds of mine truck, and its critical piece brake shoe iron is the vital part manufactured.Brake shoe iron part is framework circular arc class part, and 24 pore size distributions of part are on the arc surface of shoes, and its critical technological point is the hole machined on arc surface, and the Tolerance of Degree of position in each hole requires strict.
Solve this processing problems at present uses the numerical control device with four axles to be processed more, manufacturing enterprise's appointed condition is required height, the enterprise that must have four axles or above numerical control device could realize the processing of this type of part, this restrict the development of the enterprise of some little medium-sized, ground zeros.
Summary of the invention
The technical issues that need to address of the present invention are that the defect overcoming prior art, it is provided that a kind of brake shoe iron arc surface drilling equipment, and it can realize processing on legacy equipment radial drilling machine, and can guarantee that it processes Geometrical Tolerance Principle.
For solving the problems referred to above, the present invention adopts the following technical scheme that
The invention provides a kind of brake shoe iron arc surface drilling equipment, described brake shoe iron arc surface drilling equipment includes clamp body, part bracing frame it is provided with on clamp body, by part bracing frame, rotary shaft is installed, index plate and clamping device and handwheel are installed in rotary shaft, index plate connects indexing positioning device, indexing positioning device connecting pin treadle, installs brake shoe iron part by clamping device.
In the present invention, described clamp body has base plate, and on base plate, left and right is each provided with one block of side plate, and disposed behind have one piece of back plate, side plate is provided with bushing plate, bushing plate is provided with drill bushing.
In the present invention, described part bracing frame includes two blocks of side plates, and two blocks of side plates are respectively arranged with gusset I, gusset II, gusset III and gusset IV from bottom to top, right side side plate is provided with location-plate, gusset IV is provided with positioning boss.
In the present invention, described indexing positioning device includes a bracer, a bracer is provided with steady pin, steady pin is provided with foot-driven lever, foot-driven lever is provided with alignment pin, and foot-driven lever is connected with a bracer by spring.
In the present invention, described clamping device includes pressing plate, and one end of pressing plate is provided with housing screw, and the other end is placed on part bracing frame.
The principle of the present invention is: part is put in part bracing frame, and the six-freedom degree realizing part by positioning boss, location-plate and gusset I, gusset II, gusset III, gusset IV and housing screw limits, and completes the location of part.Simultaneously by the housing screw clamping brake shoe iron part on pressing plate；Fix, with part bracing frame, the index plate being connected and be fabricated to part tooth, the Angular Dimension of tooth is consistent with the distribution angle in hole on brake shoe iron part circular arc surface, when stepping on foot-driven lever, alignment pin (being fixed together with foot-driven lever) disengages with index plate, index plate can forward next tooth to by pulling handwheel, at this moment foot-driven lever is unclamped, foot-driven lever can be upspring under the action of the spring automatically, tooth engagement on the tooth of alignment pin termination and index plate, complete the fixing of index plate, starting four holes of a row processing on this angle arc surface, the rest may be inferred, and until processing, institute is porose.Thus achieve part by one-step clamping, complete the processing in six rows totally two ten four holes.
The present invention can make the processing in hole on the arc surface of whole brake shoe iron, all completes on radial drilling machine, and can guarantee that the decile in hole on arc surface and the position degree requirement in each hole.
Present configuration is reasonable, installs, easy to use, and only one of which housing screw compresses, the most firm but also convenient dismounting part, substantially increase hole machined precision and working (machining) efficiency on brake shoe iron arc surface, and reduce the requirement of production equipment, be suitable to middle-size and small-size, the limited enterprise of equipment and use.
