Abstract
The utility model discloses a kind of bolt cubings, including discoid detection plate, the center of detection plate is equipped with standard detection hole, the diameter in standard detection hole is consistent with the normal diameter of bolt head to be detected, the second detection hole and third detection hole are additionally provided in detection plate, the diameter of second detection hole is the upper tolerance diametral of bolt head diameter to be detected, the diameter of third detection hole is the lower tolerance diametral of bolt head diameter to be detected, second detection hole side is also convexly equipped with salient point, and third detection hole side is also recessed fluted.The bolt cubing facilitates detection bolt head diameter.
Description
Technical field:
The utility model relates to standard component fields, are especially a kind of bolt cubing.
Background technique:
There are its head of many bolts and screw rod interconnecting piece vehicle to have chamfering in existing standard component, is not easy to detect it directly with slide calliper rule
Diameter, there are large errors for testing result.
Utility model content:
Technical problem to be solved by the utility model is to provide a kind of bolt inspections for facilitating detection bolt head diameter
Tool.
The technical solution of the utility model is to provide a kind of bolt cubing, including discoid detection plate, detection plate
Center is equipped with standard detection hole, and the diameter in standard detection hole is consistent with the normal diameter of bolt head to be detected, in detection plate also
Equipped with the second detection hole and third detection hole, the diameter of the second detection hole is the upper tolerance diametral of bolt head diameter to be detected,
The diameter of third detection hole is the lower tolerance diametral of bolt head diameter to be detected, and the second detection hole side is also convexly equipped with salient point,
Third detection hole side is also recessed fluted.
After using the above structure compared with prior art, the utility model have the advantage that this structure do not need using
Slide calliper rule are detected, and not only increase detection efficiency, and precision is high.
Preferably, the second detection hole and third detection hole are symmetricly set on standard detection hole two sides.More convenient operation.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment:
The utility model is described in further detail with reference to the accompanying drawings and detailed description:
As shown in Figure 1, a kind of bolt cubing, including discoid detection plate 1, the center of detection plate 1 are equipped with standard detection hole
2, the diameter in standard detection hole 2 is consistent with the normal diameter of bolt head to be detected, and the second detection hole 3 is additionally provided in detection plate 1
With third detection hole 4, the diameter of the second detection hole 3 is the upper tolerance diametral of bolt head diameter to be detected, third detection hole 4
Diameter is the lower tolerance diametral of bolt head diameter to be detected, and 3 side of the second detection hole, which is also convexly equipped with, indicates upper tolerance detection
Salient point 5,4 side of third detection hole are also recessed with the circular groove 6 for indicating lower tolerance detection.In this way for being not easy to obscure when detecting
Upper tolerance diametral and lower tolerance diametral detect corresponding detection hole.In addition, for convenience of operating, the second detection hole and third detection hole
It is symmetricly set on standard detection hole two sides.
It by above structure, does not need to be detected using slide calliper rule, not only increases detection efficiency, and precision is high.It is logical
Cross the detection of tolerance and lower tolerance limit value, it can be ensured that product is qualified.
Only the utility model preferred embodiment is described above, but is not to be construed as the limit to claim
System.All equivalent structure or equivalent flow shifts done using the utility model specification and accompanying drawing content are included in this
Within the scope of patent protection of utility model.
Claims (2)
