A kind of embodiment of this thin-walled costal margin bar class part processing and loading clamp fixture comprises pressing plate, the first T-shaped bolt, the second T-shaped bolt, the holding nut coordinated with the first T-shaped bolt, the clamp nut that coordinates with the second T-shaped bolt, base has T-slot along its length, first T-shaped bolt and the second T-shaped bolt move horizontally in T-slot, pressing plate is fixed on the first T-shaped bolt by the holding nut of below, and pressing plate compresses blank by coordinating between clamp nut with T-shaped bolt.
A kind of embodiment of this thin-walled costal margin bar class part processing and loading clamp fixture also comprises end face locating piece, side locating piece and alignment pin, alignment pin is fixed on the working face of base, end face locating piece and side locating piece have the hole with detent fit, end face locating piece realizes blank length direction location, side locating piece realizes blank width location, and base working face realizes blank short transverse location.
The utility model thin-walled costal margin bar class part processing and loading clamp fixture achieves part processing clamped one time and completes, and achieves fast-assembling and quick position.
Accompanying drawing explanation
The structural representation of Fig. 1 the utility model thin-walled costal margin bar class part processing clamp positioning and clamping;
The structural representation of Fig. 2 the utility model thin-walled costal margin bar class part processing clamp positioning and clamping;
The structural representation of Fig. 3 the utility model thin-walled costal margin bar class part processing clamp positioning and clamping.
Detailed description of the invention
Below in conjunction with accompanying drawing 1-3, the utility model is described in further detail.
The utility model provides a kind of thin-walled costal margin bar class part processing and loading clamp fixture and comprises base 1, screw 11, base 1 upper surface is working face, multiple cavity 12 is had in the middle of base 1, equidistantly on base 1 have multiple waist-shaped hole 13, screw 11 coordinates with blank upper screwed hole through mounting hole 12 and realizes fixing in cavity 12.Base 1 is placed on the middle position of machine tool workbench, for realizing the pivot angle processing of machine tool chief axis two sides, the height dimension of base 1 is greater than the size of main tapping, guarantee that main shaft pivot angle 90 ° does not interfere, after base is put well, the working face of levelling base 1 stretching centering base 1, then firm banking 1.Blank is before putting base 1, several screwed holes need be processed in the side of blank, blank screwed hole spacing is consistent with waist-shaped hole 13 spacing of base 1, blank screwed hole diameter is consistent with the diameter of screw 11, after hole processing is good, be placed on by blank on the working face of base 1, screw 11 is connected with blank screwed hole through the waist-shaped hole 13 on base 1, in cavity 12, tighten screw 11 with clamping spanner, by blank and base 1 tightly fixing.
The utility model comprises and also comprises the T-shaped bolt 8 of pressing plate the 5, first T-shaped bolt 6, second, the holding nut 7 coordinated with the first T-shaped bolt 6, the clamp nut 9 that coordinates with the second T-shaped bolt 8, base 1 has T-slot 4 along its length, first T-shaped bolt 6 and the second T-shaped bolt 8 move horizontally in T-slot 4, pressing plate 5 is fixed on the first T-shaped bolt 6 by the holding nut 7 of below, and pressing plate 5 is by compressing blank coordinating between clamp nut 9 with T-shaped bolt 8.When blank dimension is shorter, base 1, the T-shaped bolt 8 of pressing plate the 5, first T-shaped bolt 6, second, holding nut 7 and clamp nut 9 is utilized to fix blank.Second T-shaped bolt 8 and a T-shaped bolt 6 are put into respectively the T-slot 4 of base 1, holding nut 7 is arranged on the first T-shaped bolt 6, according to the position of Height Adjustment holding nut 7 on the first T-shaped bolt 6 of blank, pressing plate 5 is through the second T-shaped bolt 8, pressing plate 5 one end is placed on holding nut 7, and the other end is placed on blank, is then assemblied in by clamp nut 9 on second T-shaped bolt 8, tighten clamp nut 9, utilizing is threaded tightly is fixed on blank on base 1.
The utility model also comprises end face locating piece 2, side locating piece 3 and alignment pin 10, alignment pin 10 is fixed on the working face of base 1, end face locating piece 2 and side locating piece 3 have the hole coordinated with alignment pin 10, end face locating piece 2 realizes blank length direction location, side locating piece 3 realizes blank width location, and base 1 working face realizes blank short transverse location.For realizing the quick position of blank, blank is placed on the working face of base 1, end face locating piece 2 is arranged on alignment pin 10, end face locating piece 2 is utilized to limit the position of blank at length direction, side locating piece 3 is arranged on alignment pin 10, utilizes side locating piece 3 to limit the position of blank at width.Because part processing clamped one time completes, therefore blank is very low in the position accuracy demand of base 1 working face, avoids the product quality problem because blank position error causes.
The utility model provides a kind of thin-walled costal margin bar class part processing and loading clamp fixture and belongs to semi-open clamping, clamping is carried out in blank side fix, opposite side freely throws the reins to, blank is not because part the first half imposes restriction in roughing process, and the stress therefore cutting generation can freely discharge; Simultaneously because part is in the symmetrical center positions of blank, the part left and right sides amount of going is comparatively even, and the cutting stress distribution of generation is also comparatively consistent, and part deformation is relatively little; To sum up two aspects are because usually seeing, adopt this fixture to carry out clamping, clamping deformation is little, are applicable to the processing of thin-walled costal margin bar class part.
