Abstract
The utility model discloses a U-shaped bolt calibration gauge, which is used by matching with a bolt column part and a thread part of a U-shaped bolt and comprises a detection plate; two first detection grooves corresponding to the stud parts are formed in the upper side of the detection plate; two second detection grooves corresponding to the thread parts are formed in the lower side of the detection plate. The utility model discloses a be equipped with the detection groove that is equipped with measuring bolt post portion and screw thread portion respectively and open a grade width on the pick-up plate, compare traditional detection mode, the utility model discloses need not use slide caliper to detect, not only improved detection efficiency, it is high to detect the precision moreover, is particularly suitable for big detection of U type bolt width of opening a grade in batches greatly.
Description
Technical Field
The utility model belongs to detect the frock field, a U type bolt is rectified and is examined utensil is related to.
Background
U-bolts, i.e. horseback bolts, known by the english name U-bolt, are non-standard elements, known by the name U-shaped, with a screw thread at both ends for coupling with a nut, mainly for fixing tubular objects such as water pipes or sheet objects such as leaf springs for automobiles.
U type bolt on the automobile bridge all has strict requirement to opening the shelves width, so width size's in U type bolt course of working is very important to the accuse, and traditional detection means adopts slide caliper direct measurement U type bolt to open the shelves width, and is inefficient, can not satisfy the requirement that industry detected in batches on a large scale.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a conveniently detect utensil of examining of U type bolt size of opening a grade.
In order to achieve the above purpose, the technical solution of the present invention is as follows:
a U-shaped bolt calibration gauge is used in cooperation with a bolt column part and a thread part of a U-shaped bolt standard part and comprises a detection plate; two first detection grooves are formed in the upper side of the detection plate; the size of the first detection groove is matched with that of the bolt part; the distance between the two first detection grooves is matched with the opening width of the bolt column part; two second detection grooves are formed in the lower side of the detection plate; the size of the second detection groove is matched with that of the threaded part; the distance between the two second detection grooves is matched with the opening width of the thread part.
The utility model discloses a theory of operation:
a detector holds the bottom of a U-shaped bolt with one hand and holds a detection plate with the other hand, when a stud part of the U-shaped bolt is detected, two first detection grooves on the detection plate are respectively clamped into two studs of the stud part, the opening width of the stud part is detected, the stud part slides back and forth along the stud part, the opening width of the stud part is qualified without resistance, the opening width of the stud part is unqualified if the stud part is resistant or can not slide, the detection plate is turned over to a second detection groove after the stud part is detected, the two second detection grooves on the detection plate are respectively clamped into threads of the threaded part, the stud part slides slowly, the opening width of the threaded part is qualified if the stud part is free from resistance, and the opening width of the threaded part is unqualified if the stud part is resistant or can not slide.
Compared with the prior art, the utility model has the advantages and beneficial effect as follows:
1. the utility model discloses a be equipped with the detection groove that is equipped with measuring bolt post portion and screw thread portion respectively and open a grade width on the pick-up plate, compare traditional detection mode, the utility model discloses need not use slide caliper to detect, not only improved detection efficiency, it is high to detect the precision moreover, is particularly suitable for big detection of U type bolt width of opening a grade in batches greatly.
2. The utility model discloses simple structure, scientific and practical, the cost is cheap, strong adaptability.

Fig. 2 is a schematic view of the top view structure of the present invention.
Fig. 3 is a schematic view of a U-bolt structure.
The attached drawings are as follows:
1-detection plate, 2-first detection groove, 3-second detection groove, 4-stud part and 5-thread part.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Example 1:
a U-shaped bolt calibration gauge is used in cooperation with a stud part 4 and a threaded part 5 of a U-shaped bolt standard component and comprises a detection plate 1; two first detection grooves 2 are arranged on the upper side of the detection plate 1; the size of the first detection groove 2 is matched with that of the bolt part 4; the distance between the two first detection grooves 2 is matched with the opening width of the stud part 4; two second detection grooves 3 are arranged on the lower side of the detection plate 1; the size of the second detection groove 3 is matched with that of the threaded part 5; the distance between the two second detection grooves 3 is matched with the opening width of the threaded part 5.
A detector holds the bottom of a U-shaped bolt with one hand and holds a detection plate 1 with the other hand, when a bolt part 4 of the U-shaped bolt is detected, two first detection grooves 2 on the detection plate 1 are respectively clamped into two bolts of the bolt part 4, the opening width of the bolt part 4 is detected, the detection plate slides back and forth along the bolt part 4, the opening width of the bolt part 4 is qualified without resistance, the opening width of the bolt part 4 is unqualified with resistance or incapability of sliding, after the bolt part 4 is detected, the detection plate 1 is turned over to a second detection groove 3, two second detection grooves 3 on the detection plate 1 are respectively clamped into threads of a thread part 5, the detection plate slowly slides on the thread part 5, the opening width of the thread part 5 is qualified without resistance, and the opening width of the thread part 5 is unqualified with resistance or incapability of sliding.
It should be understood that the above-described embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the practice of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description; this is not necessary, nor exhaustive, of all embodiments; and obvious changes and modifications may be made without departing from the scope of the present invention.
