The anti-dropping pipe joint is simple in structure and can meet the size detection requirement of the pipe joint with the anti-dropping boss.

Description

Pipe joint go and end and examine utensil

Technical Field

The utility model relates to an automobile parts size inspection frock, concretely relates to utensil is examined to leading to of coupling.

Background

Referring to fig. 1, the pass-stop detection tool of the existing pipe joint comprises a connecting rod 6, and a pass end 7 and a stop end 8 which are arranged at two ends of the connecting rod 6, wherein the pass end 7 and the stop end 8 are both of a cylinder structure, the inner diameter of a cylinder of the pass end 7 is the same as the maximum limit size of the outer diameter of the pipe joint to be detected, and the inner diameter of a cylinder of the stop end 8 is the same as the minimum limit size of the outer diameter of the pipe joint to. Whether the outer diameter of the pipe joint is qualified or not is detected by axially inserting the through end 7 or the stop end 8 of the through-stop detection tool from the end part of the pipe joint, and the product size is judged to be qualified as long as the through end 7 can be inserted and the stop end 8 cannot be inserted.

Referring to fig. 2, in order to prevent the pipe joints in many automobiles from falling off during assembly, an anti-falling boss 5 is provided at an interface portion of a pipe joint 4 to be tested. The current logical end examines the utensil and can only satisfy the detection demand that awaits measuring 4 tip of coupling, when needs detect 4 regional sizes in the middle part of the coupling that awaits measuring, leads to the end the drum of examining the utensil and will be blocked by anticreep boss 5, can't stretch into 4 middle parts of the coupling that awaits measuring and regional detect.

Disclosure of Invention

The utility model aims at providing a utensil is examined to logical ending of coupling, its simple structure can satisfy the size detection demand of the coupling of taking the anticreep boss.

The pipe joint open-end checking fixture comprises a checking fixture body, wherein the checking fixture body is provided with a checking fixture opening and a checking fixture spigot, and the checking fixture opening and the checking fixture spigot are grooves; the size of the groove opening of the checking tool through opening is the same as the maximum limit size of the outer diameter of the pipe joint to be detected, and the size of the groove opening of the checking tool spigot is the same as the minimum limit size of the outer diameter of the pipe joint to be detected.

Further, the cross section of the groove is U-shaped, rectangular or semicircular.

Further, examine a body and be rectangular form, examine a both ends of examining a body are located respectively to examine a through-hole and examine a tang, examine a through-hole and examine the recess opening orientation of a tang opposite.

The utility model discloses a to examine a mouth and examine a tang and set up to the recess, and then can follow the coupling and radially insert, can satisfy the external diameter size detection demand of ordinary coupling and the coupling of taking the anticreep boss simultaneously, expanded the application range of examining the utensil to lead to only.

The utility model discloses simple structure easily processes. And the size is smaller, and the carrying is convenient.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 3, the pipe joint pass-stop detection tool comprises a detection tool body 1, wherein the detection tool body 1 is provided with a detection tool through opening 2 and a detection tool spigot 3, the detection tool through opening 2 and the detection tool spigot 3 are grooves with U-shaped cross sections, and the cross sections of the grooves can be rectangular or semicircular and can be reasonably selected according to actual working conditions.

The opening size of the groove of the checking fixture through port 2 is the same as the maximum limit size of the outer diameter of the pipe joint 4 to be detected, and the opening size of the groove of the checking fixture spigot 3 is the same as the minimum limit size of the outer diameter of the pipe joint 4 to be detected.

Examine a body 1 and be rectangular form, in order to facilitate processing and detection, will examine a mouth 2 and examine a tang 3 and locate respectively the both ends of examining a body 1, examine a mouth 2 and examine a tang 3's recess opening opposite orientation.

During detection of the pipe joint to be detected 4 with the anti-falling boss 5, referring to fig. 4 and 5, when the pipe joint to be detected 4 with the anti-falling boss 5 is measured, the detection tool through opening 2 and the detection tool spigot 3 of the detection tool body 1 are respectively inserted into a part to be detected along the radial direction of the pipe joint to be detected 4, and the detection is completed along the axial lead of the pipe joint to be detected 4 by rotating for a circle. If examine a mouth 2 and can insert and examine a body 1 and can follow 4 axial lead rotations a week of the coupling that awaits measuring, examine a tang 3 and can not insert, then judge 4 external diameter sizes of the coupling that awaits measuring qualified. If the checking fixture through opening 2 cannot be inserted, or the checking fixture through opening 2 cannot rotate for a circle along the axial lead of the pipe joint to be measured after being inserted, or the checking fixture spigot 3 can be inserted, the pipe joint to be measured 4 is regarded as unqualified in outer diameter.

The operation of detecting the outer diameter of the common pipe joint is the same as that of detecting the outer diameter of the pipe joint 4 to be detected with the anti-falling boss 5, and the detailed description is omitted.

The utility model discloses only need one set examine the external diameter size detection demand that has just satisfied ordinary coupling and the coupling of taking the anticreep boss simultaneously, expanded the application range who leads to only examining the utensil. And the structure is simple, and the processing is easy. The size is smaller, and the carrying is convenient.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
