Abstract
The utility model discloses a measuring tool for measuring the inner ring groove depth of parts. The measuring tool comprises a main scale, a vernier scale and a depth scale, wherein the vernier scale is attached on the main scale and is capable of moving along the main scale; and the depth scale is carried by the vernier scale and moves synchronously with the vernier scale. The measuring tool is characterized in that the free end of the depth scale is provided with a measuring head capable of hooking up the upper groove wall of the inner ring groove of a part. The measuring tool disclosed by the utility model can be formed by using waste vernier calipers and has the characteristics of simpleness for manufacture, easiness for metering and maintenance, convenience for operation and the like. The measuring tool disclosed by the utility model is especially suitable for measuring the inner ring groove depth of the parts, is fast and accurate to measure, and is capable of meeting requirements on batch production.
Description
Technical field
The utility model relates to a kind of measurer that is used to measure parts endoporus even depth, especially a kind of measurer that is used to measure the parts inner groove degree of depth.
Background technology
The measurer that is used to measure hole depth in the parts in the prior art is often seen, such as a kind of vernier caliper wherein.The vernier scale that above-mentioned vernier caliper comprises main scale, be attached on the main scale and can move along main scale and carry synchronization-moving pit gauge by vernier scale; Side at main scale is provided with a secondary external pelivimetry pawl; Measuring claw in opposite side is provided with a pair, wherein an external pelivimetry pawl in the secondary external pelivimetry pawl is arranged on the main scale, and another external pelivimetry pawl is arranged on the vernier scale; An interior measuring claw in the one secondary interior measuring claw is arranged on the main scale, and measuring claw is arranged on the vernier scale in the another.The pit gauge of above-mentioned vernier caliper can only be used to measure the degree of depth of parts endoporus, is the inner groove degree of depth but measure the parts inner groove if desired to the distance of section, then can't realize.Also do not find to have the measurer that is suitable for measuring the parts inner groove degree of depth in the prior art,, will bring problems such as cost is high, efficient is low, can't satisfy batch production requirement if parts are used destructive inspection.
The utility model content
The task of the utility model is to solve the above-mentioned technological deficiency that the measurer that is used to measure parts endoporus even depth in the prior art exists, and a kind of measurer that is used to measure the parts inner groove degree of depth is provided.
Its technical solution is:
A kind of measurer that is used to measure the parts inner groove degree of depth, the vernier scale that comprises main scale, is attached on the main scale and can moves along main scale and carry and synchronization-moving pit gauge by vernier scale; Free end at above-mentioned pit gauge is provided with the gauge head that can catch on cell wall on the parts inner groove.
Downside at pit gauge is provided with rectangular recess, rectangular recess near the protuberance of free end one side as above-mentioned gauge head.
The inner face of above-mentioned gauge head is positioned at apart from 10mm place, free end bottom surface.
Side at above-mentioned main scale is provided with a secondary external pelivimetry pawl, measuring claw in opposite side is provided with a pair; Wherein an external pelivimetry pawl in the secondary external pelivimetry pawl is arranged on the main scale, and another external pelivimetry pawl is arranged on the vernier scale, and an interior measuring claw in the secondary interior measuring claw is arranged on the main scale, and measuring claw is arranged on the vernier scale in the another.
The utlity model has following useful technique effect:
The utility model can utilize the waste and old vernier caliper transformation of the way to form, and has the characteristics such as simple, that the metering maintenance is easy, easy to operate of making.The utility model is specially adapted to measure the parts inner groove degree of depth, measures quick and precisely, can satisfy the batch process needs.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Figure is the structural principle synoptic diagram of a kind of embodiment of the utility model.
Embodiment
In conjunction with accompanying drawing, a kind of measurer that is used to measure the parts inner groove degree of depth comprises main scale 1, vernier scale 2 and pit gauge 3; Above-mentioned vernier scale is attached on the main scale and can moves along main scale, and pit gauge is carried and same moved further by vernier scale.Side at above-mentioned main scale is provided with a secondary external pelivimetry pawl, measuring claw in opposite side is provided with a pair; Wherein, an external pelivimetry pawl 4 in the secondary external pelivimetry pawl is arranged on the main scale, and another external pelivimetry pawl 5 is arranged on the vernier scale, and an interior measuring claw 6 in the secondary interior measuring claw is arranged on the main scale, and measuring claw 7 is arranged on the vernier scale in the another.Free end at above-mentioned pit gauge is provided with the gauge head 8 that can catch on cell wall on the parts inner groove; Preferably, be provided with rectangular recess 9 at the downside of pit gauge, rectangular recess near a free-ended side protuberance as above-mentioned gauge head.The inner face of above-mentioned gauge head 8 is positioned at the 10mm place, free end bottom surface apart from pit gauge, and promptly the inner face of gauge head is 10mm to the distance L of free end bottom surface; Certainly L also can select other length values for use.
Except that aforesaid way, if utilize waste and old vernier caliper to transform, as long as main scale, vernier scale and the pit gauge main part is complete can realize.
Its principle of work roughly is:
When using the utility model to measure measured workpiece (parts) the inner groove degree of depth; Catch on the last cell wall of inner groove with the gauge head on the pit gauge; The slip vernier caliper until the bottom face that makes main scale with read measured result after the end face of measured workpiece overlaps; Read method is identical with vernier caliper, and the result that will read then deducts the actual grade value that above-mentioned L value promptly obtains the measured workpiece inner groove.
Need to prove that those skilled in the art can also make such or such easy variation pattern under the instruction of this instructions, such as equivalent way, or obvious mode of texturing.Above-mentioned variation pattern all should be within the protection domain of the utility model.
