Abstract
A kind of digital display dynamometer for machine static rigidity test belongs to machine tool capability or plant equipment experimental technique field.It is characterized in that: comprise steel ball from top to bottom, push rod, sensor and base can be revolved; Digital display meter is arranged on base; Steel ball is placed on the top that can revolve push rod but does not connect, and steel ball is with simulation handle of a knife or simulate workpiece point cantact, and by revolving push rod clockwise or be rotated counterclockwise, generation axial displacement, realizes compression and decompression function, thus completes and load machine tool chief axis.When carrying out load test, machine tool chief axis is after stressed, and power is delivered to lathe all parts, causes each parts of lathe to produce different shift values, by the ratio calculation of stressed size and displacement, thus obtains the Static stiffness data of machine tool chief axis or machine tool component.The utility model solves all kinds of lathe, as the static rigidity load test demand of machining center, drilling machine, milling machine, grinding machine or other plant equipment.
Description
Technical field:
The utility model is mainly used in the Static stiffness test of all kinds of lathe or plant equipment, is the portable desirable digital display dynamometer of scientific research department of manufacturing enterprise and Quality Supervision Organizations, belongs to machine tool capability or plant equipment experimental technique field.
Background technology:
The rigidity of lathe is one of important indicator determining lathe key property.The rigidity of machine tool deficiency not only affects precision and the surface quality of processing work, but also affects production efficiency owing to can not improve cutting speed and the amount of feeding.So the rigidity of lathe will be improved, carry out a large amount of Test And Research Works, need one and be more suitable for all kinds of lathe and load and easy to use, dynamometer flexibly.
Traditional dynamometer does not have charger, small-size jack is adopted to connect during Static stiffness test, load unstable, and survey sensor adopts signal wire to be connected with display device, longer signal wire has decay to force signal, need independent display device to carry out amplification process, and longer line easily cause testing crew to trip injury.
Digital display dynamometer collection charger of the present utility model, display device and device for measuring force are integrated, and small volume, power consumption is low, do not need external-connection displayer, adopt aluminum alloy base, lightweight, to carry performance good, very conveniently carries out load test to all kinds of lathes such as lathe, milling machine, drilling machine, grinding machine, machining center or other plant equipment.
Summary of the invention:
The utility model object is for machine static rigidity test Quick is for loading force display.
The utility model is integrated and battery-powered small-sized digital display dynamometer (see Fig. 1) at force cell, digital display device, charger.
Digital display dynamometer described in the utility model have volume little, use flexibly, convenient reading, weight only has 1kg, but measurement range can reach: 200N ~ 20000N (different size), is the desirable instrument of one of machine static rigidity test.
For a digital display dynamometer for machine static rigidity test, it is characterized in that: comprise steel ball from top to bottom, push rod, sensor and base can be revolved; Digital display meter is arranged on base; Steel ball is placed on the top that can revolve push rod but does not connect, and steel ball is with simulation handle of a knife or simulate workpiece point cantact, and by revolving push rod clockwise or be rotated counterclockwise, generation axial displacement, realizes compression and decompression function, thus completes and load machine tool chief axis.
When carrying out load test, machine tool chief axis is after stressed, and power is delivered to lathe all parts, causes each parts of lathe to produce different shift values, by the ratio calculation of stressed size and displacement, thus obtains the Static stiffness data of machine tool chief axis or machine tool component.
The utility model solves all kinds of lathe, as the static rigidity load test demand of machining center, drilling machine, milling machine, grinding machine or other plant equipment.
Accompanying drawing illustrates:
Fig. 1 is the schematic diagram of digital display dynamometer.
Fig. 2 is embodiment schematic diagram.
Fig. 3 is the partial enlarged drawing of Fig. 2.
1, steel ball; 2, push rod can be revolved; 3, sensor; 4, base; 5, digital display meter, 6. digital display dynamometer, 7 main shafts, 8 displays, 9 worktable.
Embodiment:
Digital display dynamometer described in the utility model is achieved by the following technical solution: by a kind of digital display dynamometer tested for machine static rigidity in Fig. 1, it is characterized in that: comprise steel ball 1 from top to bottom, can revolve push rod 2, sensor 3 and base 4; Digital display meter 5 is arranged on base 4;
Described charger is by steel ball 1 and can revolve push rod 2 and form, steel ball 1 is with simulation handle of a knife or simulate absorption surface (point cantact), by revolving push rod 2 clockwise or be rotated counterclockwise, generation axial displacement, realize compression and decompression function, thus complete machine tool chief axis is loaded.
Below in conjunction with accompanying drawing 2, for horizontal Machining centers, the utility model content is described.
A. by dynamometer as between the worktable of machining center and main shaft;
B. the correct position that declined by main shaft prepares to carry out radial loaded (when axially loading, dynamometer being overturn 90 °);
C. rotate and can revolve push rod and make steel ball contact main shaft thus to main shaft imposed load;
D. read shift value by indicator, and calculate rigidity.
