Abstract
The utility model relates to a kind of hobboing cutter outside diameter measuring instrument, comprise base plate and two sliding shoes, each sliding shoe is connected with base plate by T-shaped screw and wing nut, the bottom of sliding shoe is provided with slide key, sliding shoe is by slide key and base plate location, the middle part of base plate is provided with fixed central spindle, and fixed central spindle is connected with base plate by housing screw, and outside fixed central spindle, cover has multiple interchangeable mandrels successively.With contacting of hobboing cutter external diameter, hobboing cutter outside dimension is converted to the distance of measuring piece by sliding shoe, thereby operating personnel can utilize vernier caliper or other length measurers to measure to the distance of measuring piece the outside dimension that obtains hobboing cutter, do not need to utilize vernier caliper or milscale directly to measure position of tool tip, reduced and measured the impact of gimmick on measurement result; Sliding shoe is directly contacted with hobboing cutter point of a knife, after sliding shoe wearing and tearing, can repair by grinding off abrading section the damage of having avoided point of a knife to cause vernier caliper.
Description
Technical field
The utility model relates to survey instrument field, is specifically related to a kind of hobboing cutter outside diameter measuring instrument.
Background technology
Gear is mechanical organ common in a kind of engineering goods, and the processing of gear generally adopts hobboing cutter processing.Hobboing cutter is reaching after wear limit, need to reface, and for ensureing that hobboing cutter still can process correct gear shape after refacing, need to ensure that the hob profile after hobboing cutter sharpening is correct.According to the design concept of hobboing cutter, correct for ensureing hob profile, need change according to grinding parameter table anterior angle and the off normal value of hobboing cutter simultaneously, need to be at the external diameter of sharpening pre-test hobboing cutter anterior angle and the off normal value to determine that it is corresponding.
General adoptable scheme is for utilizing vernier caliper or milscale directly to measure two relative cutters tooth, but because hobboing cutter cutter tooth is sharper, and hobboing cutter cutter tooth be helix distribute, while utilizing vernier caliper or milscale directly to measure, measure gimmick very large on measurement result impact, be difficult to Measurement accuracy.In addition, hobboing cutter cutter tooth is sharper and hardness is high, when measurement, easily vernier caliper or milscale is caused to damage.
Summary of the invention
It is a kind of easy to use that the purpose of this utility model is to provide, and measurement result is hobboing cutter outside diameter measuring instrument accurately.
The utility model solves the technical scheme that its technical matters adopts: a kind of hobboing cutter outside diameter measuring instrument, comprise base plate and two sliding shoes, each sliding shoe is connected with base plate by T-shaped screw and wing nut, the bottom of sliding shoe is provided with slide key, sliding shoe is by slide key and base plate location, the middle part of base plate is provided with fixed central spindle, and fixed central spindle is connected with base plate by housing screw, and outside fixed central spindle, cover has multiple interchangeable mandrels successively.
Particularly, described interchangeable mandrel is located and is placed on base plate by fixed central spindle.
Particularly, described interchangeable mandrel has four.
Particularly, described slide key is fixed on sliding shoe by housing screw.
The utlity model has following beneficial effect: the utility model is converted to by hobboing cutter outside dimension the distance of measuring piece with contacting of hobboing cutter external diameter by sliding shoe, thereby operating personnel can utilize vernier caliper or other length measurers to measure to the distance of measuring piece the outside dimension that obtains hobboing cutter, do not need to utilize vernier caliper or milscale directly to measure position of tool tip, reduced and measured the impact of gimmick on measurement result; Sliding shoe is directly contacted with hobboing cutter point of a knife, after sliding shoe wearing and tearing, can repair by grinding off abrading section the damage of having avoided point of a knife to cause vernier caliper.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
In figure, 1, sliding shoe, 2, housing screw, 3, fixed central spindle, 4, interchangeable mandrel, 5, wing nut, 6, T-shaped screw, 7, base plate, 8, slide key.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.
As shown in Figure 1 and Figure 2, a kind of hobboing cutter outside diameter measuring instrument, comprise base plate 7 and two sliding shoes 1, each sliding shoe 1 is connected with base plate 7 by T-shaped screw 6 and wing nut 5, the bottom of sliding shoe 1 is provided with slide key 8, and sliding shoe 1 locates to realize the slip of sliding shoe 1 by slide key 8 and base plate 7, and the middle part of base plate 7 is provided with fixed central spindle 3, fixed central spindle 3 is connected with base plate 7 by housing screw 2, and the outer cover successively of fixed central spindle 3 has multiple interchangeable mandrels 4.
Particularly, described interchangeable mandrel 4 is placed on base plate 7 by fixed central spindle 4 location.
Particularly, described interchangeable mandrel 4 has four.
Particularly, described slide key 8 is fixed on sliding shoe 1 by housing screw 2.
In the time measuring hobboing cutter external diameter, according to hobboing cutter, endoporus is installed and is selected suitable interchangeable mandrel, unclamp wing nut, remove sliding shoe, put into hobboing cutter, mobile both sides sliding shoe makes it contact with hobboing cutter point of a knife, rotates hobboing cutter and makes sliding shoe at highest distance position, utilize wing nut to compress sliding shoe, utilize vernier caliper measurement two sliding shoe inner distance can draw hobboing cutter external diameter.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
Technology, shape, structure part that the utility model is not described in detail are known technology.
