Description

Eccentric indexing anchor clamps
Technical field
The utility model relates to a kind of machining equipment, particularly relates to a kind of eccentric indexing anchor clamps.
Background technology
Be used for fixing processing object in the machine-building process, make it to occupy correct position, the device to accept construction or to detect claims again anchor clamps.On lathe during processing work, for the surface energy that makes workpiece reach the drawing regulation size, geometry and with other surperficial specification requirements such as relative-position error, workpiece must be installed (location) before the processing, clip (clamping).Anchor clamps are comprised of setting element, clamping device, tool setting induction element, indexing means, Connection Element and clamp body etc. usually.Because the type of product is various, the type of required anchor clamps is also different.
Adopt traditional handicraft to add man-hour, mainly have following shortcoming:
1, for the different anchor clamps of the production of different eccentric throws, different angles, increased the cost of making mould;
2, every equipment must be equipped with scroll chuck, need repeat to proofread and correct and clamping device wave
Take anchor clamps and debug man-hour;
3, every equipment must be equipped with tailstock, needs the operator to compress by hand product, increases operator's labour intensity.
The utility model content
The purpose of this utility model is to provide a kind of accurate positioning, clamping is firm and applicability is strong eccentric indexing anchor clamps.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of eccentric indexing anchor clamps, and it comprises axis terminal pad, mid-game, panel, guide pillar, pull-rod nut, pull bar main shaft, two holding nut seats, adjusting bolt, the eccentric index dial of frock, tooling sleeve, pull bar, pressing plate; Described tooling sleeve is installed in the end face of the eccentric index dial of frock, the eccentric index dial of frock is installed in the end face of panel, two holding nut seats are installed in respectively the diagonal angle of panel end face, and adjusting bolt is screwed onto on the holding nut seat and its inner leaning on the sidewall of the eccentric index dial of frock; The two ends of described guide pillar are fixed in respectively on axis terminal pad and the panel, and the stage casing of guide pillar is actively socketed in the mid-game, and guide pillar evenly distributes in mid-game; The upper end of pull-rod nut is fixed in the bottom surface of mid-game, and the lower end of pull-rod nut penetrates the mesopore of axis terminal pad and the top of pull bar main shaft is spirally connected; Offer a loose slot in the bottom surface of mid-game, described pull bar passes the eccentric index dial of tooling sleeve, frock and mid-game from top to bottom, and the bottom of pull bar penetrates in the loose slot of mid-game bottom surface and with nut and is spirally connected the loose slot matched in clearance of this nut and mid-game bottom surface; Described pressing plate is plugged on the top of pull bar.
The utility model also comprises locating piece, and this locating piece is fixed on the end face of tooling sleeve.
Described guide pillar has more than three or three.
After adopting such scheme, the utlity model has following advantage:
1, since the utility model by pull bar main shaft, pull-rod nut, middle plate, pull bar and pressing plate with Workpiece clamping to be processed on the end face of tooling sleeve, overall structure is simple, clamping is firm; The utility model is adjusted the location of workpiece by the adjusting bolt that is screwed onto on the holding nut, and is easy to operate.
2, the product of same serial model No., size, different eccentric throw, different angles can be finished at this case anchor clamps, reduces clamp material and makes man-hour the reduction cost.
3, every equipment needn't be equipped with scroll chuck and repeat and proofread and correct and clamping device, reduces anchor clamps and debugs man-hour.
When 4, debugging the product of different eccentric throws, different angles, only need slight eccentric throw size and the angle of adjusting eccentric indexing to finish, convenient, quick.
5, every equipment needn't be equipped with tailstock, and the compression mode is automatic impaction, and press force is stable, firm, consistent, convenient, and fast upper-lower product reduces operator's labour intensity, reduces product up and down during the lineman.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is top view of the present utility model;
Fig. 3 is clamped condition figure of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is a kind of eccentric indexing anchor clamps, and it comprises axis terminal pad 1, mid-game 2, panel 3, two guide pillars 4, pull-rod nut 5, pull bar main shaft 6, two holding nut seats 7, adjusting bolt 8, the eccentric index dial 9 of frock, tooling sleeve 10, pull bar 20, locating piece 30, pressing plate 40.
Described tooling sleeve 10 is installed in the end face of the eccentric index dial 9 of frock, the eccentric index dial 9 of frock is installed in the end face of panel 3, two holding nut seats 7 are installed in respectively the both sides of panel 3 end faces, and adjusting bolt 8 is screwed onto on the holding nut seat 7 and its inner leans on the sidewall of the eccentric index dial 8 of frock.
