Abstract

The invention relates to a device base movable gasket machining method and relates to the field of machining. The method includes the following steps: measuring; recording data and conducting mapping analysis, wherein the measured size refers to the actual size obtained after a gasket is matched; blanking; milling the gasket to the required length and width, removing 1-2mm for the thickness of the gasket, and utilizing the milled plane as the reference face for marking a line; marking the line; lathing, adopting a four-jaw chuck to clamp a lathe workpiece, adjusting the lathing cutter edge to be meshed with the marked line before clamping, not clamping the gasket too tightly at first, enabling the lathing cutter to approach the line marking position of the gasket, rotating a claw plate to see whether the marked line is consistent with the lathing cutter, and conducting adjustment on no consistency. The method is simple in machining process, ensures machining quality and size accuracy of the workpiece, is high in machining efficiency, saves working hours, and reduces production cost.

Description

Plant bottom case removable insole pieces processing method

Technical field

The present invention relates to field of machining, be specifically related to plant bottom case removable insole pieces processing method.

Background technology

In marine engine room installation, relate to the equipment that a large amount of appearance and size is comparatively large and axis is longer, as windlass, warping winch, steering wheel, horizontal crossing cabin pump etc., these equipment have very high installation specification.Adopt the method for removable insole pieces to improve intermediate calibrating of axis precision and play a part to support, reinforce to equipment lateral force, therefore how fast, creative activity pad in high quality, vital effect is played to the installation accuracy and enhance production progress improving plant equipment.

Current pattern legal system makes removable insole pieces, relatively be applicable to large batch of equipment install, but for the processing of single removable insole pieces, this method is just not too applicable, because shim size there occurs change, pattern originally can not be used, and again must make pattern, this not only adds the construction cost of boats and ships. but also can increase and execute the fourth time, affect manufacturing schedule.

Summary of the invention

In order to solve the problem, the invention provides a kind of process simple, ensure workpiece processing quality and dimensional accuracy, and working (machining) efficiency be high, save man-hour, reduce the plant bottom case removable insole pieces processing method of production cost.

Present device base removable insole pieces processing method, comprises the following steps:

The first step, measure, first plant bottom case and setting-up piece are adjusted before measurement, reach state in desirable school, after equipment is adjusted to the right place, just can measure, the principle of a plane is determined according to 3, as long as the spacing on three summits between setting-up piece on measurement device base and pedestal, during measurement. the height of this point is first measured with bow compass, to take out gently and by the adjustment screw means of wild card, then measure the size of bow compass two bayonet socket with outside micrometer, draw plant bottom case and with the actual size of determining between pad;

Second step, after dimensional measurement, recorded data, plot analysis, measured size refer to pad brush good after actual size, during drawing, 3 sizes will be increased the brush surplus of 0.15 ~ 0.20mm, the size on pad 4 summits is the thickness after lathe process, and another gauge calculates according to the data of other 3 points, this size does not make processing request, is just convenient to the line of lathe process previous crops with reference to using;

3rd step, blanking, the measure obtained in second step, for convenience of processing, blanking will put sufficient surplus, and thickness direction will increase 3mm-4mm, and length and width increase 5mm-7mm;

4th step, Milling Process, first by pad length and width Milling Process to required size, and by spacer thickness size mill off lmm mono-2mm, mill out the plane the come datum level as line;

5th step, line, platform carries out line processing to milling part, take datum level as starting point, mark the height point at pad 4 angles, then coupled together by 4 points with vernier height gauge;

6th step, lathe process, lathe workpiece adopts chuck clamping, before clamping, adjustment lathe tool mouth coincide with the line pulled, first tightly against do not clamp pad, by the position that lathe tool is rule near pad, rotary pawl dish, see that whether line is consistent with lathe tool, if inconsistent. remake and adjust, pad can be knocked gently with copper rod, being used for adjusting position makes it consistent, after adjusting, start lathe to process, processing time-division roughing and fine finishining two operations, when size will put in place, measure once with outside micrometer, see that the thickness of 4 points is whether close to the requirement of drawing, if difference is too many, pad will be readjusted, as far as possible consistent with lathe tool, ensure work pieces process size.

Process of the present invention is simple, ensure workpiece processing quality and dimensional accuracy, and working (machining) efficiency is high, saves man-hour, reduces production cost.

Detailed description of the invention

Present device base removable insole pieces processing method, comprises the following steps:

The first step, measure, first plant bottom case and setting-up piece are adjusted before measurement, reach state in desirable school, after equipment is adjusted to the right place, just can measure, the principle of a plane is determined according to 3, as long as the spacing on three summits between setting-up piece on measurement device base and pedestal, during measurement. the height of this point is first measured with bow compass, to take out gently and by the adjustment screw means of wild card, then measure the size of bow compass two bayonet socket with outside micrometer, draw plant bottom case and with the actual size of determining between pad;

Second step, after dimensional measurement, recorded data, plot analysis, measured size refer to pad brush good after actual size, during drawing, 3 sizes will be increased the brush surplus of 0.15 ~ 0.20mm, the size on pad 4 summits is the thickness after lathe process, and another gauge calculates according to the data of other 3 points, this size does not make processing request, is just convenient to the line of lathe process previous crops with reference to using;

3rd step, blanking, the measure obtained in second step, for convenience of processing, blanking will put sufficient surplus, and thickness direction will increase 3mm-4mm, and length and width increase 5mm-7mm;

4th step, Milling Process, first by pad length and width Milling Process to required size, and by spacer thickness size mill off lmm mono-2mm, mill out the plane the come datum level as line;

5th step, line, platform carries out line processing to milling part, take datum level as starting point, mark the height point at pad 4 angles, then coupled together by 4 points with vernier height gauge;

6th step, lathe process, lathe workpiece adopts chuck clamping, before clamping, adjustment lathe tool mouth coincide with the line pulled, first tightly against do not clamp pad, by the position that lathe tool is rule near pad, rotary pawl dish, see that whether line is consistent with lathe tool, if inconsistent. remake and adjust, pad can be knocked gently with copper rod, being used for adjusting position makes it consistent, after adjusting, start lathe to process, processing time-division roughing and fine finishining two operations, when size will put in place, measure once with outside micrometer, see that the thickness of 4 points is whether close to the requirement of drawing, if difference is too many, pad will be readjusted, as far as possible consistent with lathe tool, ensure work pieces process size.

Should note when measuring following some: measure the bow compass bayonet socket that uses and want point, to ensure that measurement data is correct; Surveying 3 points as far as possible will near with the angle of determining pad, to obtain peak; When surveying most, bow compass is vertical with plant bottom case.Note impartially, to ensure certainty of measurement.

Process of the present invention is simple, ensure workpiece processing quality and dimensional accuracy, and working (machining) efficiency is high, saves man-hour, reduces production cost.
