Description

High-accuracy Location Clamping Tool for Drilling Hole

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to for workpiece being carried out to the positioning fixture of Drilling operation.

Background technology

Workpiece 14 as shown in Figure 1, it is with cylindrical section 11, the cylindrical of cylindrical section 11, with rectangle platform 12, need to process locating hole 13 now on cylindrical section 11, and it is being positioned and is adding man-hour, use plain clamp to acquire a certain degree of difficulty to its location, especially to guarantee machining accuracy, must use special-purpose frock just can meet the demands, and frock must be easy to use, clamping efficiency is high, can guarantee its machining accuracy again simultaneously.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of high-accuracy Location Clamping Tool for Drilling Hole, and it is simple in structure, flexible and convenient to use, and clamping efficiency is high, and machining accuracy is high.

The technical scheme that the utility model adopts is as follows:

High-accuracy Location Clamping Tool for Drilling Hole, comprise clamp column and locating cover, in clamp column with limiting stand, the cylindrical of limiting stand is with detection faces, on the end face of limiting stand with locating ring, the cylindrical of locating ring is with drill jig and U-lag, and the axis of drill jig is parallel with detection faces, and U-lag is two and symmetrical about the axis of locating ring; Locating cover is with centre bore, and the inner circle of centre bore is with step and internal thread, and described internal thread matches with the external screw thread of locating ring cylindrical, and the cylindrical of locating cover is with through hole and draw-in groove.

The utility model has the advantage of: according to the structure of workpiece, the cylindrical that locating ring workpiece is set on positioning table carries out spacing, U-lag on locating ring coordinates with rectangle platform on workpiece and prevents to rotate, use locating cover to carry out spacing to the other end of workpiece, locating cover inner circle is threaded and step is conveniently located and installation and the location to workpiece of locating ring, positioning table cylindrical mills out detection faces, whether the location of workpiece is accurately first judged, yield rate and machining accuracy have been guaranteed, simple in structure, flexible and convenient to use, clamping efficiency is high, and machining accuracy is high.

Accompanying drawing explanation

Fig. 1 is the structural representation of workpiece.

Fig. 2 and Fig. 3 are structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As shown in Figure 1 to Figure 3, the utility model comprises clamp column 1 and locating cover 7, in clamp column 1 with limiting stand 2, limiting stand 2 can play spacing effect to workpiece 14 end faces, the cylindrical of limiting stand 2 is with detection faces 4, whether accurate by judging whether detection faces 4 vertically can detect the location of workpiece 14, on the end face of limiting stand 2 with locating ring 3, the cylindrical of locating ring 3 is with drill jig 5 and U-lag 6, the axis of drill jig 5 is parallel with detection faces 4, be beneficial to by the state of the state judgement drill jig 5 of detection faces 4, U-lag 6 is two and symmetrical about the axis of locating ring 3, during location, rectangle platform 12 on workpiece 14 is stuck in U-lag 6, locating cover 7 is with centre bore 8, the inner circle of centre bore 8 is with step and internal thread, described internal thread matches with the external screw thread of locating ring 3 cylindricals, the cylindrical of locating cover 5 is with through hole 9 and draw-in groove 10, by draw-in groove 10, can use the instruments such as spanner that locating cover 7 is tightened on locating ring 3, determine that through hole 9 does not block after drill jig 5, can directly by drill jig 5, on the cylindrical 11 of workpiece 14, process locating hole 13,

Using method of the present utility model is as follows:

The first step, is loaded on clamp column 1 on operating desk;

Second step, puts into locating ring 13 by workpiece 14, and the rectangle platform 12 on workpiece 14 is stuck in U-lag 6;

The 3rd step, is threaded onto locating cover 5 on locating ring 3 cylindricals, and the described step of centre bore 8 inner circles is matched with the end face of workpiece 14;

The 4th step, inserts in draw-in groove 10 with instruments such as spanners, makes the through hole 9 on locating ring 3 cylindricals not interfere drill jig 5;

The 5th step, judgement detection faces 4 is after vertical state, by drill jig 5, on the cylindrical 11 of workpiece 14, processes locating hole 13.

More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
