Compared with prior art, the advantage of this programme is: by arrange on bed die connection fixed thereto column and It is provided with the bearing of hole clipping corresponding with column, bearing is fixedly connected on side form, so that side form passes through card when installing positioning Hole is observed that whether column targeted by hole clipping, so that installation is positioned and is easier to operate to；Can be slided by arranging on bearing Fixture, fixture is connected with bearing by fastening screw, and fastening screw is provided with the nut offseting with bearing, by adjusting nut To control glide direction on bearing for the fixture and distance, thus realize fixture offset with column or from state, from Without loosening because making connection produce using abrasion.

As preferred scheme, described fixture includes level board and riser, and between level board and column, this erects riser The shape of plate is mated with the shape of cross section of column.Be conducive to, after gusset is offseted with column, three water being limited simultaneously Square to displacement.

As preferred scheme, described level board is provided with bar hole, the length direction of this bar hole and fastening screw Axis direction is parallel, and described bearing is provided with the bolt matching with bar hole.Be easy to make the direction of motion of level board with tight Gu the direction of motion of screw rod is identical, be conducive to making the effect of regulation the most obvious；Connected by bolt simultaneously, easy to disassemble and Install.

As preferred scheme, the cross section of described column is triangle.Be conducive to saving the production material of column.

As preferred scheme, the bottom of described column is provided with the sole vertical with column axis, this sole and riser position In the homonymy of column, this sole is connected with bed die by bolt.During fixing device work, column is mainly held with the connection end of bearing Be subject to is moment of flexure, is provided with beneficial to simplification structure by such.

Brief description

Fig. 1 makes the top view of the structural representation of device of fuel pump impeller sand mo(u)ld for the present invention；

Fig. 2 makes the front view of the structural representation of device of fuel pump impeller sand mo(u)ld for the present invention.

Specific embodiment

With reference to the accompanying drawings and examples technical solution of the present invention is further illustrated:

In figure: side form 1, bearing 2, bar hole 3, bolt 4, level board 5, column 6, riser 7, adjusting nut 8, block 9th, fastening screw 10, sole 11, fastening bolt 12, bed die 13, hole clipping 14.

The device of making fuel pump impeller sand mo(u)ld as depicted in figs. 1 and 2 understands, is welded with the middle part of the arranged on left and right sides of side form 1 Shape is in the bearing 2 of cuboid, and the middle part of bearing 2 is provided with the rectangular hole clipping of shape 14, is provided with block in the right part of bearing 2 9.Block 9 is integrally formed with bearing 2, and the center of block 9 is provided with through hole.The top of bearing 2 is provided with the level board 5 of rectangle, level The forward and backward two ends of plate 5 are provided with bar hole 3.Bearing 2 is provided with the bolt 4 matching with bar hole 3, and level board 5 passes through bar Shape hole 3 and bolt 4 cooperation are realized and being slidably connected of bearing 2.The left side central portion of level board 5 has " v " font Groove, is welded with the riser 7 that shape matches therewith in groove.The left side wall of riser 7 is in triangle with the shape of cross section through hole clipping 14 The column 6 of shape offsets.Weld with fastening screw 10 in the middle part of the right-hand member of level board 5.The right part of fastening screw 10 passes through the logical of block 9 Hole, the part that fastening screw 10 is located at block 9 left side is provided with adjusting nut 8.The bottom welding of column 6 has sole 11, sole 11 Left side flush with the edge of column 6, the right part of sole 11 is connected by fastening bolt 12 with bed die 13.

During use, first rotate adjusting nut 8, so that level board 5 is slided to the right, increase the distance between riser 7 and side form 1, It is easy to column 6 to pass through.Then from the top of bed die 13, side form 1 is placed on bed die, and makes column 6 pass through hole clipping 14.Finally Rotate adjusting nut 8, so that level board 5 is slided to the left, riser 7 is offseted with column 6.The fixing device on side form 1 both sides is all pressed so Mode operates the fixed installation that just can complete between side form 1 and bed die 13.

Above-described is only the preferred embodiment of the present invention it is noted that for a person skilled in the art, On the premise of without departing from present configuration, some deformation can also be made and improve, these also should be considered as the guarantor of the present invention Shield scope, these are all without the effect affecting present invention enforcement and practical applicability.
