Abstract
The utility model relates to an examining and repairing device for parallelism of a large micrometer and is suitable for repairing and examining the parallelism of the large micrometer, and comprises a platform, a fixed clamping device, a calibrating member, etc., which are matched with simple structures. The optical parallel and the calibrating member or the measuring block of the examining and repairing device for parallelism of a large micrometer are matched to repair and exam the parallelism of the large micrometer on the utility model directly with no intermediate links. The utility model has the advantages of small size, high work efficiency, guaranteed quality, funds saving, material saving, etc.
Description
The utility model is a kind of large-scale milscale depth of parallelism device of examining and determine and repair, and is used for repairing and calibrating to the large-scale milscale depth of parallelism.
To large-scale milscale, the particularly repairing of the large-scale milscale depth of parallelism and calibrating more than 300 millimeters is in general measurement verification unit, still a difficult problem that does not have fine solution.The conventional method of repairing and examine and determine the milscale depth of parallelism is; Press the measurement range of milscale, as 0-25 25-50 50-75 75-100 millimeter etc., one group of four mill with the size correspondence grind repairing, check with the one group four corresponding optical parallels of size again.Because large scale mill and optical parallel are made difficulty, mill commonly used is in 150 millimeters, and the mill production of 150-300 millimeter is few, and uses difficulty.Not not producing more than 300 millimeters, and optical parallel has only 100 millimeters with interior, the where the shoe pinches that the large-scale milscale depth of parallelism that Here it is is repaired and examined and determine.
Write by Zhengzhou City's measuring control, in " omnipotent measurer repairing " book that China Machine Press 1976 publishes,, also only mentioned several tool and methods of repairing of only being used to about data such as " repairings of large-scale milscale planarity and collimation ".The structure of these instruments is all complicated, uses the difficulty of operation also bigger, and intermediate link is many, introduces various errors easily.
The purpose of this utility model provides a kind of device, with mill and the optical parallel of repairing 100 millimeters following small size milscale depth of parallelisms of calibrating, the depth of parallelism of repairing and examining and determine large-scale milscale.
The utility model tightens up anchor clamps by a platform, and several members simple in structure such as calibrating device and cushion block cooperate to be formed.Fastener is connected with the T type groove of platform by bolt, can move arbitrarily and fixing along T type groove, is used for the large-scale milscale repairing and examine and determine waited of clamping and supporting different size.When being used to repair, match, grind repairing by the method for repairing the small size milscale with calibrating device and mill.When being used to examine and determine, optical parallel and calibrating device or gauge block are combined on the platform, carry out depth of parallelism inspection, adopting the utility model to repair and examine and determine the large-scale milscale depth of parallelism has following advantage:
1, simple in structure, parts are few, and low cost of manufacture is easy to use.
2, do not have intermediate link in the use, can improve work efficiency, ensure the quality of products.
3, the precision height of small size mill and optical parallel, expensive few, subassembly is only used three, and the accuracy requirement of large-scale milscale is low, not only can satisfy the requirement of its precision, and expense is very low.
4, saving fund and material use the utility model that a large amount of large-scale mill of saving more than 150 millimeters is reached about large-scale cubing and instrument.
Concrete structure of the present utility model since following examples and accompanying drawing provide:
Accompanying drawing 1 is the synoptic diagram that provides according to the utility model: the 1st, and platform, the 2nd, tighten up anchor clamps, the 3rd, supporting fixture, the 4th, calibration rod, the 5th, calibration supporting mass, the 6th, T-slot, the 7th, level, the 8th, the mill in the repairing state, the 9th, large-scale milscale to be repaired.
Platform has three adjustable support pin, and by adjusting the horizontality from level 7 finders, platform has T type groove 6, anchor clamps 2 and 3 can fixedly wait the large-scale milscale repairing or examine and determine on T type groove optional position.
Accompanying drawing 2 is to tighten up anchor clamps, mainly plays the fixed ruler frame, the 10th, tighten up spiral shell spare, and the 11st, chi frame fastener, the 12nd, the carrying plane of chi frame.Supporting fixture 3 has certain gradient with the difference that tightens up anchor clamps 2 at its supporting surface 12, shown in double dot dash line.Contact with chi frame face by adjusting, fix by tightening up spiral shell spare 10 again, make milscale avoid the influence of gravity and pressure,, can also calibrate the distortion of micrometer stand simultaneously to guarantee the quality of maintenance.
Accompanying drawing 3 is calibrating devices, the 13rd, and self-aligning bearing, the 14th, Adjusting bolt Adjusting screw, the 15th, hold-down nut, the 16th, T-slot nut.The calibration rod can be made 100 200 300 millimeters equidimensions, and diameter is identical, two of each sizes, and one is used for repairing, and one is used for calibrating.The end face of calibration rod has higher hardness, the depth of parallelism is not less than the fourth class gauge block of corresponding size, overlap for being slidingly matched with supporting mass, supporting mass 5 mainly is made up of a housing and self-aligning bearing etc., make the calibration rod in use have the ability of automatic aligning, by swivel nut 14 nuts 15 and 16 can the up-down adjustment calibrating device height, to adapt to the different-thickness of micrometer stand.
