Description
Technical Field
The utility model relates to a measuring tool, especially a measuring tool of inclined hole grinding volume belongs to and detects instrument technical field.
Background
The assembly relation among mechanical parts in the mechanical industry is complex, especially, the matching requirement on some inner holes is extremely strict, when the machine runs for a period of time, the bottom of the inner hole must be ground so as to meet the matching requirement for use, and the grinding of the bottom of the inner hole and the grinding amount of the bottom of the inner hole directly influence the performance of parts. At present, the measurement of the grinding quantity of the bottom of the inner hole is not provided with a mature measuring tool, the operation is very difficult during the measurement, the measurement error is large, the working efficiency is low, and especially the measurement of the grinding quantity of the bottom of the inclined hole is more difficult.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, convenient operation, inclined hole bottom grinding quantity measuring tool that measuring error is little.
The utility model discloses a following technical scheme realizes:
a measuring tool for the grinding quantity of the bottom of an inclined hole comprises a supporting plate, a sleeve and a measuring rod; the upper end of the sleeve extends into the mounting hole in the middle of the support plate, and the upper end of the sleeve is fixedly connected with the support plate through a positioning pin; scales are arranged at the upper end of the measuring rod, the shape of the bottom of the measuring rod is matched with the shape of the bottom of the inclined hole to be measured, and the upper end of the measuring rod is movably sleeved in the sleeve; during measurement, the bottom of the supporting plate is supported on the surface of the part, the measuring rod extends into the inclined hole to be measured, and the step at the bottom of the measuring rod is attached to the step at the bottom of the inclined hole to be measured.
The object of the invention is further achieved by the following technical measures.
In the aforementioned measuring tool for polishing the bottom of the inclined hole, the bottom of the supporting plate is an inclined surface.
In the aforementioned measuring tool for the bottom grinding amount of the inclined hole, the inclination of the bottom of the supporting plate matches the inclination of the inclined hole to be measured.
In the foregoing measuring tool for polishing amount of bottom of inclined hole, the top of the supporting plate is provided with a plurality of detachable screw holes.
The utility model discloses simple structure, it is with low costs, through measuring before the grinding and the height value between grinding back measuring staff top and the backup pad top, alright reach twice difference in height value for the grinding volume of inclined hole bottom step, it is very convenient to operate, and the method is showy to be understood. Wherein the inclination of backup pad bottom matches with the inclination of the inclined hole that awaits measuring, and the measuring staff location is accurate when guaranteeing to measure to guarantee measuring result's accuracy, the sleeve can play the guide effect to the measuring staff, makes the measuring staff be difficult for taking place the skew in measurement process, the utility model discloses measuring result is accurate, and measuring error is little, and work efficiency is high, and the commonality is strong.
The advantages and features of the invention will be illustrated and explained by the following non-restrictive description of preferred embodiments, which are given by way of example only with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic perspective view of the present invention;
FIG. 2 is a schematic structural view of the positioning pin connecting support plate and the sleeve of the present invention;
fig. 3 is a schematic structural view of the utility model for measuring the grinding amount at the bottom of the inclined hole.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 and 2, the present invention includes a support plate 1, a sleeve 2 and a measuring rod 3. The bottom 11 of backup pad 1 is the inclined plane, and the inclination of the bottom 11 of backup pad 1 matches with the inclination of the inclined hole 4 that awaits measuring, and the top of backup pad 1 is equipped with two dismouting screw 12, is convenient for install and takes out this device. The upper end of the sleeve 2 extends into the mounting hole in the middle of the support plate 1, and the upper end of the sleeve 2 is fixedly connected with the support plate 1 through a positioning pin 5. The upper end of the measuring rod 3 is provided with a scale 31, the bottom shape of the measuring rod is matched with the bottom shape of the inclined hole 4 to be measured, the upper end of the measuring rod 3 is sleeved in the sleeve 2 and can move up and down along the inner hole of the sleeve 2, during measurement, the bottom 11 of the supporting plate 1 is supported on the surface of a part, the measuring rod 3 extends into the inclined hole 4 to be measured, and the bottom step of the measuring rod 3 is attached to the bottom step 41 of the inclined hole 4 to be measured.
The method for measuring the grinding quantity of the inclined hole to be measured comprises the following steps:
as shown in fig. 3, before the grinding, will the utility model discloses support 4 upsides in the inclined hole that awaits measuring on the part surface, and stretch into the measuring staff 3 in the inclined hole 4 that awaits measuring, make the bottom step of measuring staff 3 and the laminating of the bottom step 41 of the inclined hole 4 that awaits measuring, the scale 31 through the measuring staff 3 upper end reads out height value h1 between measuring staff 3 top and the backup pad 1 top this moment, inclined hole bottom step 41 grinds the back, read out the height value h2 between grinding back measuring staff 3 top and the backup pad 1 top with same method, twice difference of height value h1-h2 is the grinding volume of inclined hole bottom step 41 promptly.
In addition to the above embodiments, the present invention can also have other embodiments, and all technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
