Abstract

The utility model discloses a device used for detecting distance and parallelism of center lines of two holes. The device comprises a first detecting axis and a second detecting axis, wherein the first detecting axis is a semi-circular axis, the side line direction of the first detecting axis is parallel to the axis direction of the first detecting axis, and the second detecting axis is a circular axis. Compared with the prior art, the center lines of the holes to be measured are substantialized through the two detecting axes, so as to further conveniently measure the distance and the parallelism between the center lines of the holes.

Description

A kind of device that is used to detect the two centerline holes distance and the depth of parallelism
Technical field
The utility model relates to a kind of pick-up unit, relates in particular to a kind of device that is used to detect the two centerline holes distance and the depth of parallelism.
Background technology
In machining is produced, the distance and the depth of parallelism between the center line in two holes of frequent needs detection.In the prior art, this detects and adopts " three-dimensional " measuring machine to finish usually.But, adopt " three-dimensional " when measuring machine detects special charges, under the efficient, can't be implemented on the assembly line and measure fast.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of replacement " three-dimensional " measuring machine to carry out the device of the two centerline holes distance and the measurement of paralleism.
For solving the problems of the technologies described above, the utility model provides a kind of pick-up unit with following structure:
A kind of device that is used to detect the two centerline holes distance and the depth of parallelism comprises that first detects axle and second and detect axle, and described first to detect axle be the semicircle axle, and its sideline direction is parallel with its axis direction, and described second detection spool is a circular shaft.
Preferably, described first end that detects axle is provided with the boss vertical with its axis direction, and described boss is provided with threaded hole or bolt via hole.
Preferably, described first detect the plane that axle is provided with the depth of parallelism detection that be used for support belt table gauge head realization directions X parallel with its axis direction.
Preferably, also be provided with shape and the adaptive jag of gaging hole to be checked on the end face of the described first detection axle.
Preferably, described second end that detects axle is provided with the boss vertical with its axis direction, and described boss is provided with threaded hole or bolt via hole.
Preferably, described second end that detects axle is provided with shape vertical with its axis direction and the adaptive jag of another gaging hole to be checked.
Compared with prior art, the utility model detects the center line hypostazation that axle will need the hole detected by two, and then the distance and the depth of parallelism between the center line of measured hole easily.
Description of drawings
Fig. 1 is the front view of pick-up unit described in the utility model;
Fig. 2 is the cut-open view of A-A direction among Fig. 1, and wherein I is first detection position, and II is second detection position, e is two centre distance between the gaging hole to be checked, L is the numerical value that records on first detection position, and R is the radius of the first detection axle, and r is the radius of the second detection axle;
The solid assembling synoptic diagram that Fig. 3 is to use this device to measure.
Employed other marks are respectively in the above accompanying drawing:
1-first detects axle, 2-parts to be detected, and 3-second detects axle, 4-hexagon head bolt, 5-dial gauge gauge head, 6-clamping screw, 7-dial gauge.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.
As shown in Figure 1 to Figure 3, the device that is used to detect the two centerline holes distance and the depth of parallelism described in the utility model comprises that first detects axle 1 and second and detect axle 3, and described first to detect axle 1 be the semicircle axle, its sideline direction is parallel with its axis direction, and the described second detection axle 3 is a circular shaft.Be provided with the boss vertical with its axis direction at described first end that detects axle 1, described boss is provided with threaded hole or bolt via hole, during use, by bolt 4 this first detection axle 1 is fixed on the parts 2 to be detected.Also be provided with size and the adaptive jag of gaging hole to be checked on the end face of the boss of the described first detection axle 1, be used for originally first detecting 1 o'clock location of axle in installation.Described second end that detects axle 3 is provided with the boss vertical with its axis direction, and boss is provided with threaded hole or bolt via hole, and its effect is in use this second detection axle to be fixed on the parts 2 to be detected.
During measurement, by shown in Figure 2 the first detection axle, the 1 and second detection axle, 3 two of putting into respectively in the UUT 2 are treated in the gaging hole earlier, and tighten with bolt.Use dial gauge 7 to be placed on the first detection position I and the second detection position II respectively then, measure two numerical value, the difference of these two numerical value is two nonparallelism of center line on directions X for the treatment of gaging hole.In like manner, use vernier card or caliper-gauge to measure the numerical value of the first detection position I and the second detection position I I respectively, its difference is exactly the nonparallelism of two centerline holes to be detected in Y direction.Centre distance computing formula between two gaging holes to be checked is: e=L-(R+r), and e is two centre distance between the gaging hole to be checked in the formula, and L is the numerical value that records on first detection position, and R first detects the radius of axle, and r second detects the radius of axle.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
