Description

A kind of grinding machine yoke plate positioning tool
Technical field
The utility model relates to and for distich plate parts, carries out the device of supporting and location on a kind of M2110A/2 of being arranged on precision internal grinder, belongs to metalworking technology field.
Background technology
While using precision internal grinder distich plate parts (referring to Fig. 1) to carry out grinding, because part cannot directly be installed, need to use frock to carry out supporting and location to part.At present, when the inwall in two holes of distich plate parts carries out grinding, general is all to utilize the chuck of M2110A/2 precision internal grinder to carry out clamping workpiece, once can only clamping one, and because part is little, centering is wasted time and energy, and not only greatly reduces the working (machining) efficiency of workpiece, and cannot guarantee two hole centre-to-centre spacing.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of easy to operate, quick, and the grinding machine of accurate positioning yoke plate positioning tool, to improve the internal grinding efficiency of connection plate parts, guarantees the machining accuracy of workpiece.
Problem described in the utility model realizes with following technical proposals:
A kind of grinding machine yoke plate positioning tool, formation comprises base, alignment pin, pressing plate, pressing plate trip bolt, center and fastening screw, described base is arranged on grinding machine by chuck, on it, be provided with centre bore and dowel hole, the centre-to-centre spacing of the two equals to join the centre-to-centre spacing in two holes on plate parts, described center is coaxially inlaid in centre bore, the diameter of its internal diameter and fastening screw matches, described alignment pin is inserted in dowel hole, and described pressing plate is pressed in workpiece on base and by pressing plate trip bolt and is connected with base.
Above-mentioned grinding machine yoke plate positioning tool, described pressing plate is stripe board, and on the workpiece of one side pressure on base, the other end is spent and withstands on base to base direction bending 90, and the middle part of pressing plate is connected with base by pressing plate trip bolt.
Above-mentioned grinding machine yoke plate positioning tool, described alignment pin and dowel hole interference fits, the diameter of alignment pin equals the aperture of finished product yoke plate, described fastening screw and center interference fits, the diameter of fastening screw is less than the aperture of finished product yoke plate.
The utility model utilizes pressing plate, alignment pin and fastening screw to locate connection plate parts, there is positioning precision high, low cost of manufacture, the advantage such as easy to operate, quick, and once can process two yoke plates, greatly improved working (machining) efficiency and the machining accuracy of workpiece.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of connection plate parts;
Fig. 2 is explosive view of the present utility model;
Fig. 3 installs schematic diagram additional while being first hole of grinding;
Fig. 4 installs schematic diagram additional while being second hole of grinding.
In figure, each label is: 1, base, 2, pressing plate, 3, center, 4, pressing plate trip bolt, 5, alignment pin, 6, yoke plate (workpiece), 7, fastening screw, 8, centre bore, 9, dowel hole, 10, pressing plate trip bolt hole.
The specific embodiment
Referring to Fig. 2, the utility model comprises round pie base 1, pressing plate 2, center 3, pressing plate trip bolt 4, alignment pin 5 and fastening screw 7, is provided with centre bore 8, dowel hole 9 and pressing plate trip bolt hole 10 on base 1.
Base 1 is fixed on precision internal grinder by chuck, base is positioned to four paws clamping centering base end face and cylindrical, error requirements≤0.01mm.
Pressing plate 2 is connected by the pressing plate trip bolt hole 10 of pressing plate trip bolt 4 and base 1, plays the effect that compresses connection plate parts.
Alignment pin 5 plays the effect of part location.
Pressing plate trip bolt 4 is for being fixed on base 1 by pressing plate 2.
Two yoke plates 6 position by pressing plate 2 and alignment pin 5 and fastening screw 7.
Referring to Fig. 3, processing is during the first hole, first by fastening screw 7 through the first hole of workpiece to the center 3 in centre bore 8, position, with 2 pairs of two yoke plate parts of pressing plate, compress, extract fastening screw 7, then process grinding.
Referring to Fig. 4, while processing the second hole, alignment pin 5 is inserted in dowel hole 9 by the first hole, the first hole to workpiece positions, fastening screw 7 inserts in the center 3 in centre bore 8 by the second hole of workpiece, and the second hole is positioned, and then with pressing plate 2, part is compressed, extract fastening screw 7, grinding is carried out in the second hole.
The utility model adopts pressing plate, alignment pin and fastening screw to position part, and two yoke plates of clamped one time, the advantage such as have simple to operate, clamping good rigidly, positioning precision is high, easy to maintenance.By varying sized, the utility model also can be to there being centre bore to position apart from other part requiring.
