Abstract
The utility model belongs to machining technology and provides a clamp for processing a plurality of elongated holes. The clamp mainly comprises a bottom plate 1, a side plate 2 and a pressure plate 6, wherein the side plate 2 is vertical to the bottom plate 1; the side plate 2 is provided with a locating pin 3 that is used for aligning the position of a workpiece 9 when in processing; the bottomplate 1 is provided with a guide pin 4 and the guide pin 4 corresponds to the elongated hole of the workpiece 9; and the bottom plate 1 is provided with a stud 5, the pressure plate 6 is sheathed at the upper part of the stud 5 which is also sheathed with a spring (8). The clamp has reasonable design and simple structure, realizes the high-precision processing of the plurality of elongated holes on a numerical control milling machine or a vertical processing center, reduces equipment investment and is short in production cycle and therefore suitable for processing products that are small in batch, diversified in variety and short in development cycle in the existing automobile industry.
Description
Technical field
The utility model belongs to machining technique, relates generally to a kind of anchor clamps of processing a plurality of elongated hole.
Background technology
The product of automobile industry often has on the face a plurality of slightness holes of processing and aperture and axiality have high requirements, distance is very little between the Kong Yukong, can't process with the multiaxis special plane, the required precision height, machine tool processing does not reach requirement, this kind situation, most producers adopt the rotary table two ends processing of horizontal Machining centers, or adopt turnover fixture to process on vertical machining centre.Process on horizontal Machining centers, because horizontal Machining centers equipment purchasing cost height, every greatly about more than 2,000,000 yuan, make the processing cost of this product on this procedure exceed 4～5 times of machine tool operations.Adopt turnover fixture on vertical machining centre, to process, because the design charges of the turnover fixture on the machining center and processing charges approximately need about 8～100,000 yuan, the design and need about about two months process time, this is not suitable for the diversity of the product of present automobile industry, allegro requirement.
Summary of the invention
The purpose of this utility model is to propose a kind of anchor clamps of processing a plurality of elongated hole, to overcome long problem of prior art production cost height or process-cycle.
The utility model realizes that the technical scheme that its goal of the invention is taked is: a kind of anchor clamps of processing a plurality of elongated hole, it mainly comprises base plate, side plate and pressing plate, described side plate is vertical with base plate, have on the side plate and be used to make workpiece to add the alignment pin of centering position in man-hour, has pilot pin on the described base plate, pilot pin is corresponding with the elongated hole of workpiece, with so that the elongated hole of described workpiece is turned the position after the processing of last work step position, realizes the continuation processing of elongated hole and guarantees machining accuracy; Base plate is provided with double-screw bolt, and pressing plate is nested with on double-screw bolt top, in order to make Work-sheet pressing through nut screwing clamping, also is equipped with spring on the double-screw bolt.
The utility model is reasonable in design, and is simple in structure, makes the high accuracy processing of a plurality of elongated hole of processing realization on CNC milling machine or vertical machining centre, reduced equipment investment; With short production cycle, thereby be suitable for present automobile industry small lot, many kinds, the product processing that the construction cycle is short.

Fig. 1 is the structural representation of the utility model anchor clamps.
Fig. 2 is the utility model clamp working-station schematic diagram.
Among the figure, 1, base plate, 2, side plate, 3, alignment pin, 4, pilot pin, 5, double-screw bolt, 6, pressing plate, 7, nut, 8, spring, 9, workpiece.
The specific embodiment
The embodiment that provides in conjunction with the accompanying drawings further is illustrated the utility model:
Shown in 1, the utility model is by base plate 1, side plate 2 and pressing plate 6, described side plate 2 is vertical with base plate 1, have on the side plate 2 and be used to make workpiece 9 to add the alignment pin 3 of centering position in man-hour, has pilot pin 4 on the described base plate 1, pilot pin 4 is corresponding with the elongated hole of workpiece 9, with so that the elongated hole of described workpiece 9 is turned the position after the processing of last work step position, realizes the continuation processing of elongated hole and guarantees machining accuracy; Base plate 1 is provided with double-screw bolt 5, and pressing plate 6 is nested with on double-screw bolt 5 tops, in order to tighten through nut 7 workpiece 9 is compressed, and also is equipped with spring 8 on the double-screw bolt 5.
Shown in 2, the utility model adopts the processing mode of two work steps to work continuously, alignment pin 3 on the anchor clamps of a plurality of elongated hole of described processing and pilot pin 4 respectively corresponding two work steps, realization location in the technology locating hole of processing in advance on the workpiece is inserted by alignment pin 3 in position in alignment pin 3 correspondences, pilot pin 4 is inserted in the elongated hole that another workpiece in the last working cycles carried out part processing, realize the hi-Fix of this workpiece, by pressing plate 6 two workpiece 9 are compressed synchronously again, adopt processing of vertical numerical control milling machine or vertical machining centre to process automatically, realize the part processing of alignment pin 3 corresponding workpiece elongated hole and whole processing of pilot pin 4 corresponding workpiece elongated hole simultaneously.The utility model adopts the processing mode of two work steps to make the workpiece upturned position in station processing carry out follow-up processing to elongated hole at two stations, at a station new workpiece of clamping one again, can realize so continuously producing in batches simultaneously.
With the workpiece shown in Fig. 2 is example, its three through-hole apertures are φ 10, hole length 220, pitch-row is 25, and the position degree requires φ 0.10, and the hole linearity requires φ 0.10, perpendicularity requires φ 0.10,4000 of month demands can be analyzed from above requirement, can reach φ about 0.20 with drill jig Working position degree on the radial drilling machine, though it is economical but do not reach requirement, processed hole is many, and pitch-row is again little, so special equipment can not be realized, be again in batches, so have only the Digit Control Machine Tool of using, and horizontal Machining centers processing, convenient and simple precision can reach but cost is too high.On used anchor clamps two stations of the utility model two holes corresponding with pilot pin 4 are to adopt same Digit Control Machine Tool to process at a station, guarantee machining accuracy like this, adjust two station programs by examination processing, and the main shaft of numerical control machine tool rigidity, can guarantee reaching in the φ 0.07 of two elongated hole of processed workpiece.For workpiece of the same type, the position that only need change procedure and change alignment pin and cutter pin gets final product.If the elongated hole of processing step shape then can select for use vertical machining centre to realize processing by tool changing.If the utility model is used for processing single through hole, then Digit Control Machine Tool changes plain radial drilling machine into, then can reduce the cost of lathe greatly.
