Description
Technical field
The utility model relates to a kind of detection utensil of mechanical part center hole size.
Background technology
In part machinery processing, center pit will directly affect the machining precision of part as the benchmark of following process, therefore needs to guarantee the consistance of center hole size.General employing vernier caliper comes the size in inspection center hole at present, but the impact of the acceptor center hole conical surface, the error of this kind detection mode reaches about 0.2mm, and measuring error is larger, can not guarantee the requirement of following process, and detects operation inconvenience, and detection efficiency is low.
Summary of the invention
The purpose of this utility model is to provide a kind of Central of the parts hole size cubing, and whether the size that detects the Central of the parts hole with easily and fast, exactly meets the requirements.
Central of the parts hole size cubing described in the utility model comprises cubing body, dial gauge and sounding rod, offers axle center hole on the cubing body, and this axle center hole is stepped hole, and dial gauge is fixed on an end of cubing body, and its table bar is positioned at this axle center hole; Sounding rod is positioned at axle center hole and the cubing body is slidingly matched, the one end is provided with detection head, and sounding rod offers stopper slot being provided with the shaft shoulder near the detection head place on the sounding rod, be connected with stop screw at the cubing body, the stop screw front end is arranged in described stopper slot; Be set with Compress Spring on the sounding rod, the Compress Spring two ends act on respectively on the step end face of the end face of the described shaft shoulder and axle center hole, under the Compress Spring effect, the detection head of sounding rod one end protrudes from the end face of cubing body, and the other end end face of sounding rod and the contact of dial gauge are inconsistent.
Further, for the ease of the installation of dial gauge and the convenience of cubing processing technology, end at described cubing body is mounted with dial framework, and described dial gauge table bar is fixed on this dial framework by trip bolt, makes dial gauge be fixed on an end of cubing body by dial framework.
The using method of above-mentioned cubing is as follows:
1. cubing check and correction: the detection head of sounding rod is stretched in the center pit of standard component, take the size of the center pit of this standard component as standard value, presses down the cubing body, the lower surface of cubing body is close to the end face of standard component after, again with the dial gauge pointer to zero.
2. parts measurement: the same with the cubing proofreading method, the detection head of sounding rod is stretched in the center pit of tested part, and the lower surface of cubing body and the end face of tested part are close to, observe the numerical value of dial gauge indication, this numerical value is the difference of tested part center pit and standard component center hole size again, if this difference is in the error range that allows, then this tested part center pit is qualified, otherwise if this difference exceeds error range, then this tested part center pit is defective.
Central of the parts hole size cubing described in the utility model, by the error amount of the direct display measurement of dial gauge, precisely directly perceived, measuring accuracy can reach 0.01mm, has guaranteed the requirement of Measurement accuracy center hole size.And this cubing simple, convenient and quick improved detection efficiency.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figures 1 to 4, this Central of the parts hole size cubing comprises cubing body 1, dial gauge 2 and sounding rod 3, offers axle center hole 11 on the cubing body 1, and this axle center hole 11 is stepped hole.One end of dial gauge 2 is mounted with dial framework 6, and the table bar 21 of dial gauge 2 is fixed on this dial framework 6 by trip bolt 7, makes dial gauge 2 be fixed on an end of cubing body 1 by dial framework 6, and its table bar 21 is positioned at the axle center hole 11 of cubing body 1.Sounding rod 3 is positioned at axle center hole 11 and is slidingly matched with cubing body 1, the one end is provided with detection head 31, sounding rod 3 is being provided with the shaft shoulder 32 near detection head 31 places, offer stopper slot 33 on the sounding rod 3, be connected with stop screw 5 at cubing body 1, stop screw 5 front ends are arranged in described stopper slot 33.Be set with Compress Spring 4 on the sounding rod 3, Compress Spring 4 two ends act on respectively on the step end face of the end face of the described shaft shoulder 32 and axle center hole 11, under Compress Spring 4 effects, the detection head 31 of sounding rod 3 one ends protrudes from the end face 12 of cubing body 1, and the other end end face of sounding rod 3 is then inconsistent with the contact 22 of dial gauge 2.
The stop screw 5 of above-mentioned cubing cooperates with stopper slot 33, has controlled the height of detection head 31 outstanding cubing body 1 end faces 12 of sounding rod 3.
As shown in Figure 5, this standard component 8 is used for the check and correction of above-mentioned cubing.During the cubing check and correction, the detection head 31 of sounding rod 3 extend in the center pit 81 of standard component 8, presses down cubing body 1, make the end face 12 of cubing body 1 be close to the end face of standard component 8, adjust at last dial gauge 2, the pointer of dial gauge 2 is made zero, can begin the tested part center pit is detected.
