Abstract
The utility model relates to a detection instrument field of U type bolt transition circular arc specifically is a U type bolt transition circular arc cardboard for the vehicle. The problem of the technique of the detection difficulty that exists when whether according with the designing requirement of present detection U type bolt transition circular arc is solved. A U type bolt transition circular arc cardboard, is including being flat go side and not -go -end, the one end of go side and not -go -end all is the arc surface, the circular arc and the lower limit that is detected U type bolt transition circular arc permissible variation of go side equal that the circular arc and the upper limit that is detected U type bolt transition circular arc permissible variation of not -go -end equal. Traditional measurement mode adopts the circular arc digital display calliper to measure, but because U type bolt transition circular arc comprises different circular arcs, uses conventional measurement mode very inconvenient, just inaccurate, and detection efficiency is on the low side. Adopt the utility model discloses U type bolt transition circular arc cardboard reduces inspection personnel's work load, improvement test efficiency, and the testing process saves time, and the testing result is accurate.
Description
Technical field
The utility model relates to the testing tool field of vehicle U-bolt transition arc, specifically a kind of U-bolt transition arc clamp.
Background technology
At present in auto manufacturing, use U-bolt very general, and belong to key components and parts.It is mainly used in connecting the parts such as leaf spring peace weighing apparatus axle, leaf spring and vehicle bridge, LNG gas support and vehicle frame.Whether the transition arc of U-bolt is one of main matching requirements with coordinating object to fit.If do not fit after the transition arc assembling of U-bolt, car load will be caused to run the transition arc of U-bolt after a period of time or coordinating object to have inordinate wear in various degree (assembling binding face is less cause), U-bolt screw-down torque is decayed rapidly, cause U-bolt to loosen, have a strong impact on car load safety traffic.Therefore before assembly, detect U-bolt transition arc and require very rigorous and strict.Traditional metering system adopts circular arc digital display calliper to measure, but be made up of different circular arc due to U-bolt transition arc, and use routine measurement mode very inconvenient and inaccurate, detection efficiency is on the low side.
Summary of the invention
The utility model is solve the detection difficult, the inefficient technical matters that detect at present and exist when whether U-bolt transition arc meets designing requirement, provides a kind of U-bolt transition arc clamp.
The utility model realizes by the following technical solutions: a kind of U-bolt transition arc clamp, comprises and be flat go side and not-go-end; One end of described go side and not-go-end is all in arc surface; The circular arc of go side is equal with the lower limit of detected U-bolt transition arc permissible variation, and the circular arc of not-go-end is equal with the upper limit of detected U-bolt transition arc permissible variation.
Detecting U-bolt transition arc is by the following method: go side contacts with U-bolt transition arc, and center section is fitted, and does not fit (Fig. 2), be considered as meeting go side from centre to extension, both sides; Not-go-end contacts with U-bolt transition arc, and center section is not fitted, and from centre to extension, both sides laminating (Fig. 3), is considered as meeting not-go-end; U-bolt transition arc meets clamp go side and not-go-end testing requirement simultaneously, and it is qualified to be considered as; U-bolt transition arc meets clamp go side or not-go-end and U-bolt transition arc and fits completely (Fig. 4), and it is qualified to be considered as; Otherwise, defective.
The beneficial effect compared with prior art had: traditional metering system adopts circular arc digital display calliper to measure, but because U-bolt transition arc is made up of different circular arc, use routine measurement mode very inconvenient and inaccurate, detection efficiency is on the low side.Adopt the utility model U-bolt transition arc clamp can reduce workload, the raising checkability of reviewer, testing process saves time, and testing result is accurate.
Accompanying drawing explanation
Fig. 1 is the structural representation of U-bolt transition arc clamp described in the utility model.
Fig. 2 is use schematic diagram one of the present utility model.
Fig. 3 is use schematic diagram two of the present utility model.
Fig. 4 is use schematic diagram three of the present utility model.
In figure: 1-go side, 2-not-go-end, 3-U type bolt.
Embodiment
A kind of U-bolt transition arc clamp, comprises and is flat go side 1 and not-go-end 2; One end of described go side 1 and not-go-end 2 is all in arc surface; The circular arc of go side 1 is equal with the lower limit of detected U-bolt transition arc permissible variation, and the circular arc of not-go-end 2 is equal with the upper limit of detected U-bolt transition arc permissible variation.
During concrete enforcement, U-bolt transition arc clamp go side 1 and not-go-end 2 adopt the margin of safety of tolerance range to be 0.03mm.The lower end of go side 1 and not-go-end 2 is all in inverted trapezoidal, and width reduces gradually, with satisfied detection needs.
Claims (2)
1. a U-bolt transition arc clamp, is characterized in that, comprises and is flat go side (1) and not-go-end (2); One end of described go side (1) and not-go-end (2) is all in arc surface; The circular arc of go side (1) is equal with the lower limit of detected U-bolt transition arc permissible variation, and the circular arc of not-go-end (2) is equal with the upper limit of detected U-bolt transition arc permissible variation.
2. U-bolt transition arc clamp according to claim 1, is characterized in that, described go side (1) and not-go-end (2) adopt the margin of safety of tolerance range to be 0.03mm.
