Abstract
The utility model discloses a double-expansion type locating clamp for an air compressor case cylinder hole. The double-expansion type locating clamp for the air compressor case cylinder hole is characterized by sequentially comprising a bottom board, a corner board, a clamp board, a pull expansion type round pin, a pull expansion type rhombus pin, a supporting block, a sequence valve and a corner cylinder; the corner board is arranged on the bottom board; the clamp board is arranged on the corner board; the supporting block, the sequence valve, the corner cylinder, the pull expansion type round pin and the pull expansion type rhombus pin are arranged on the clamp board. The double-expansion type locating clamp for the air compressor case cylinder hole has the advantage that as the cylinder hole is located in a gapless mode, the requirement for shape and size precision of machining of an air compressor case is met.
Description
Technical field
The utility model belongs to clamping tool for machine work design field, is specifically related to the two formula positioning fixtures that rise in air compressor machine casing cylinder hole.
Background technology
Location, air compressor machine casing cylinder hole adopts fixed round pin and chamfered edge finger setting at present, and alignment pin and cylinder hole exist gap.For the location of this form, do not ensure the morpheme dimension precision requirement of air compressor machine casing processing.
Utility model content
In order to overcome above-mentioned defect, the utility model has designed the two formula positioning fixtures that rise in a kind of air compressor machine casing cylinder hole.
The technical solution of the utility model is achieved in that
The two formula positioning fixtures that rise in air compressor machine casing cylinder hole, comprise successively base plate, gusset, jig plate, draw the formula circular pegs that rises, draw the parts such as formula rhombus pin, back-up block, sequence valve, corner cylinder that rise.Draw the formula circular pegs that rises to be formed by taper pin, tapered sleeve, top cap, pull bar, scuffing of cylinder bore.Draw the formula rhombus pin that rises to be formed by chamfered edge taper pin, tapered sleeve, top cap, pull bar, scuffing of cylinder bore.It is characterized in that, described gusset is arranged on base plate, and described jig plate is arranged on gusset, described in draw the formula circular pegs that rises to be arranged on jig plate, be enclosed within on taper pin and move by pull bar, top hatband mantle by scuffing of cylinder bore, thus tapered sleeve spreading.The described formula rhombus pin that rises that draws is arranged on jig plate, and be enclosed within on chamfered edge taper pin and move by pull bar, top hatband mantle by scuffing of cylinder bore, thus tapered sleeve spreading.Described back-up block, sequence valve, corner cylinder are arranged on jig plate.
Workpiece cylinder hole inserted and draw the formula circular pegs that rises, draw and rise on formula rhombus pin, cylinder hole end surface leans against on back-up block, and in oil circuit, after logical oil, scuffing of cylinder bore will draw the formula circular pegs that rises, draw the tapered sleeve spreading rising on formula rhombus pin, makes tapered sleeve contact location with cylinder hole gapless.After sequence valve, corner cylinder is by Work-sheet pressing.
The beneficial effects of the utility model are: because cylinder hole adopts gapless location, ensured the morpheme dimension precision requirement of air compressor machine casing processing.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further explained to explanation.
As shown in Figure 1,2,3, 4, the two formula positioning fixtures that rise in air compressor machine casing cylinder hole, comprise successively base plate 1, gusset 4, jig plate 3, draw the formula circular pegs 14 that rises, draw the parts such as formula rhombus pin 15, back-up block 5, sequence valve 2, corner cylinder 6 that rise.Draw the formula circular pegs 14 that rises to be formed by taper pin 12, tapered sleeve 11, top cap 13, pull bar 9, scuffing of cylinder bore 8.Draw the formula rhombus pin 15 that rises to be formed by chamfered edge taper pin 10, tapered sleeve 11, top cap 13, pull bar 9, scuffing of cylinder bore 8.It is characterized in that, described gusset 4 is arranged on base plate 1, and described jig plate 3 is arranged on gusset 4, described in draw the formula circular pegs 14 that rises to be arranged on jig plate 3, drive tapered sleeve 11 to move on taper pin 12 by scuffing of cylinder bore 8 by pull bar 9, top cap 13, thus tapered sleeve 11 spreadings.The described formula rhombus pin 15 that rises that draws is arranged on jig plate 3, drives tapered sleeve 11 to move on chamfered edge taper pin 10 by scuffing of cylinder bore 8 by pull bar 9, top cap 13, thus tapered sleeve 11 spreadings.Described back-up block 5, sequence valve 2, corner cylinder 6 are arranged on jig plate 3.
Workpiece 7 cylinder holes inserted and draw the formula circular pegs 14 that rises, draw and rise on formula rhombus pin 15, cylinder hole end surface leans against on back-up block 5, in oil circuit, after logical oil, scuffing of cylinder bore 8 will draw the formula circular pegs 14 that rises, draw tapered sleeve 11 spreadings that rise on formula rhombus pin 15, makes tapered sleeve 11 contact location with cylinder hole gapless.After sequence valve 2, corner cylinder 6 compresses workpiece 7.
The above; it is only preferably detailed description of the invention of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; be equal to replacement or changed according to the technical solution of the utility model and utility model design thereof, within all should being encompassed in protection domain of the present utility model.
