Abstract
The utility model discloses a contour cushion piece. The section of the contour cushion piece is roughly I-shaped, an inverted T-shaped groove is lengthwise arranged on the upper part block body of the contour cushion piece, two rows of through-holes are lengthwise arranged on the lower part block body thereof, the upper surface of the upper part block body of the contour cushion piece parallels to the lower surface of the lower part block body, the amount of the two rows of through-holes on the lower part block body is four every row, and the parallelism between the upper surface of the upper part block body of the contour cushion piece and the lower surface of the lower part block is equal to or smaller than 0.005 mm. The undersurface of the contour cushion piece is connected with a clamping fixture, the surface is connected with a workpiece, the inverted T-shaped groove is arranged on the upper part block part, and the function thereof is the same as the clamping fixture, thereby greatly improving the serviceable range and the practicability of the clamping fixture, decreasing the investment of the auxiliary tools, such as the clamping fixture, and effectively saving the production cost.
Description
Technical field
The utility model relates to a kind of servicing unit of frock clamp.
Background technology
In the process that large gear is processed, could process after need positioning it by relevant frock clamp, the parts of place work piece are commonly referred to mold in these frock clamps.Because the positioning combination face of mold all is solid shape usually, can only be applicable to the part in some fixed size scopes when positioning centering with mold, therefore for different big or small workpiece, use the mold of corresponding size to fix, this makes that not only the input of equipment is bigger, and the many occupations of land of mold are also bigger.
The utility model content
The purpose of this utility model is to overcome the problems referred to above, and providing can be so that corresponding mold be applicable to the contour pad spare of various workpieces in a kind of the use.
The technical scheme that realizes the utility model purpose is: a kind of contour pad spare, and the cross section of described contour pad spare is I shape substantially; Block upper edge, the top length direction of contour pad spare is provided with an inverted T shape groove; Be provided with two exhausting holes on the block of its underpart along its length; The upper surface of the top block of contour pad spare parallels with the lower surface of bottom block.
The quantity of two exhausting holes on the block of described bottom is 4 of every rows.
The depth of parallelism≤0.005mm between the upper surface of the top block of described contour pad spare and the lower surface of bottom block.
The utlity model has positive effect: the bottom surface of contour pad spare of the present utility model is connected with mold, the surface is connected with workpiece, and on the block of top, be provided with the inverted T shape groove, its function is identical with mold, the scope of application and the practicality of mold have been improved so greatly, reduce the input of mold class auxiliary mould, saved production cost effectively.
Description of drawings
Fig. 1 is the structural representation of contour pad spare of the present utility model;
Fig. 2 is that A among Fig. 2 is to view;
Fig. 3 is the use schematic diagram of contour pad spare of the present utility model.
Mark in the above-mentioned accompanying drawing is as follows:
Contour pad spare 1, inverted T shape groove 11, through hole 12, mold 2, workpiece 3, short T type bolt 4, long T type bolt 5, pressing plate 6, nut 7.
The specific embodiment
See Fig. 1 and Fig. 2, the cross section that is used for the contour pad spare 1 of auxiliary mold centering of the present utility model is I shape substantially.Its block upper edge, top length direction is provided with an inverted T shape groove 11.Be provided with two exhausting holes 12 on the block of its underpart along its length, the quantity of every exhausting hole 12 is 4, and the axis and the horizontal plane of each through hole 12 are perpendicular.The upper surface of the top block of contour pad spare 1 parallels with the lower surface of bottom block, and the mutual depth of parallelism≤0.005mm.
See Fig. 3, during use, form one group by 3～6 these contour pad spares 1 usually, every group contour, and error is in 0.005mm.According to the clamping workpiece requirement, regulate the distance of 1 of each contour pad spare, the short T type of two exhausting holes, the 12 usefulness bolt 4 by each contour pad spare bottom surface is fixed on contour pad spare 1 on the mold 2 then.Then proofread and correct flatness≤0.01 of the upper surface between each contour pad spare 1.
Penetrate the T connector of 2 long T type bolts 5 in the inverted T shape groove 11 of each contour pad spare 1, the tail end of each long T type bolt 5 protrudes upward from the inverted T shape groove 11 of contour pad spare 1.Again workpiece 3 is placed on each contour pad spare 1, and the location datum level of workpiece 3 is contacted with the upper surface of each contour pad spare 1, and make that long T type bolt 5 passes workpiece 3 from bottom to top.Be enclosed within on the long T type bolt 5 with pressing plate 6 then, again nut 7 screwed on long T type bolt 5 and workpiece 3 is clamped by pressing plate 6.
In actual production, when processing the part of different cylindrical sizes, as long as regulate the fitting limit of contour pad spare group, can saving fixedly like this, the input of mold also can reduce a lot owing to change the unproductive time that mold produces.
Claims (3)
1, a kind of contour pad spare is characterized in that: the cross section of described contour pad spare (1) is I shape substantially; Block upper edge, the top length direction of contour pad spare (1) is provided with an inverted T shape groove (11); Be provided with two exhausting holes (12) on the block of its underpart along its length; The upper surface of the top block of contour pad spare (1) parallels with the lower surface of bottom block.
