CN201291383Y - Radial equant hole drilling universal jig of circular mechanical product - Google Patents

Abstract

The utility model relates to a mechanical machining tool, particularly relating to a universal clamp used for radial equant drilling of a round mechanical product, which comprises a compaction bolt, an upper baffle, pressure plates, a V-shaped base, a lower baffle and a round mechanical product. An equant positioning plate is arranged on the upside of the V-shaped base, between the upper baffle and the lower baffle; an equant positioning hole is bored on the equant positioning plate; bores are arranged on the pressure plates at two sides of the upper baffle; and the upper baffle and the lower baffle are fixed together through the compaction bolt. The universal clamp can satisfy the radial equant drilling requirements of the round mechanical production through the compaction bolt, the upper pressure plate, the pressure plates, the equant positioning plate, the lower baffle and the V-shaped base, and reduces work intensity, saves cost and improves work efficiency and quality.

Description

Circular engineering goods radially wait the branch borehole universal fixturing

Technical field:

The utility model relates to machine tools, and especially circular engineering goods radially wait the branch borehole universal fixturing.

Background technology:

Traditional mechanical industry all adopts manual equal portions circumference when carrying out the round piece line, existence is rule inaccurate, and as using dividing head line efficient low, boring centering difficulty and working (machining) efficiency are hanged down and can not be satisfied in enormous quantities, and made with high precision needs.

The utility model content:

The utility model purpose is in order to overcome above-mentioned shortcoming, and the circular engineering goods that provide radially wait the branch borehole universal fixturing.These anchor clamps need not rule to workpiece during use, and the boring centering is by drill jig, and Equal round is finished by the five equilibrium location-plate, can process the external diameter difference, and isodisperse inhomogeneity product improves work efficiency, guarantees machining accuracy, reduces cost.

For achieving the above object, the utility model is made up of hold-down bolt, overhead gage, pressing plate, V-type base, lower baffle plate, circular engineering goods; There is a five equilibrium location-plate to be seated in above the V-type base between described overhead gage and the lower baffle plate, on the five equilibrium location-plate, is drilled with the five equilibrium locating hole, on two side guides of overhead gage, boring is arranged, be fixed together with hold-down bolt between the last lower baffle plate.

This use is novel compared with prior art to have outstanding feature, and this device is by hold-down bolt, branch location-plate and lower baffle plate and V-type bases such as top board, pressing plate, can satisfy circular machinery generation and radially wait the branch borehole needs, reduce labour intensity, save cost, increase work efficiency and quality.

Description of drawings:

Fig. 1 is the utility model structural representation.

The specific embodiment:

The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing:

Among the figure by, 1, hold-down bolt, 2, overhead gage, 3, pressing plate, 4, the five equilibrium location-plate, 5, the V-type base, 6, lower baffle plate, 7, circular engineering goods, 8, the five equilibrium locating hole, 9, boring forms.

Hold-down bolt 1 is that a threaded screw mandrel of double headed roller is that circular engineering goods 7 compress by overhead gage 2, lower baffle plate 6 usefulness pressing plates 3 with workpiece among the figure, make it motionless, overhead gage 2 by two screws be fixed on pressing plate 3 above, V-type base 5, be used for putting and put engineering goods 7, overhead gage above it 2 and below lower baffle plate 6 between be fixed with five equilibrium location-plate 4 with screw, lower baffle plate 6 is a rectangle, semi arch on the last end face and lower baffle plate 6 fix, this is drilled with locating hole 8 above plate, the baffle plate at overhead gage two ends has boring 9.During use, earlier anchor clamps are fixed on the Drilling machines bench.According to the drawing requirement, determine the axial distance in hole by regulating lower baffle plate, according to branch location-plates 4 such as selections such as hole count such as branch such as grade, workpiece is placed on the V-type base again, last lower baffle plate restriction workpiece moves axially, and is located.By hold-down bolt 1 workpiece is compressed with pressing plate, it can not be moved, by pressing plate 3 drill jigs guiding, process a hole, unclamp hold-down bolt 1, rotational workpieces aligns the hole of intact hole of firm brill and five equilibrium location-plate 4, reprocesses next hole.According to said method can process not a plurality of machining holes of equivalent scores.

Claims (1)

1, circular engineering goods radially wait the branch borehole universal fixturing, are made up of hold-down bolt (1), overhead gage (2), pressing plate (3), V-type base (5), lower baffle plate (6), circular engineering goods (7); It is characterized in that, there is a five equilibrium location-plate (4) to be seated in above the V-type base (5) between described overhead gage (2) and the lower baffle plate (6), on five equilibrium location-plate (4), be drilled with five equilibrium locating hole (8), on two side guides (3) of overhead gage (2), boring (9) is arranged, be fixed together with hold-down bolt between the last lower baffle plate.
