Description
Technical field
The utility model belongs to mechanical manufacturing field, particularly a kind of Closely locking nut pretightening force measuring apparatus.
Background technology
In certain model aircraft product development is produced, for ensureing the consistance of Closely locking nut product quality, simulation installation test need be carried out to this product, and pretightning force test measurement is carried out to the product after installing.Tested verifying whether the mechanical property after processing physical dimension, thermal treatment, list processing (LISP) in its process meets standard-required by pretightning force.In the pretightning force test in early stage, on main employing cupping machine, pretightning force measured by original coupling arrangement.The shortcoming of the method is: 1, after two Connection Blocks are connected with sensor connecting piece not point-blank, there will be in test and have other power effects, the numerical value that impact is measured, 2, because the plane roughness contacted with nut end face is poor, material hardness is not high, just a part and the frock that can contact with frock because of nut end face in experimentation occur being out of shape and accurately can not reflect pretension force value situation of change in pretightning force process of the test, thus be that in the research and development of accurate analytic product, Problems existing brings larger difficulty, great impact is caused on the research and development progress of product.
Utility model content
The purpose of this utility model is to provide provides a kind of pretightening force measuring apparatus that can use on cupping machine, this device is in nut pretension process, by the sensor feedback on testing machine on computing machine, and the power situation of change of pretension process is reflected in real time with figure and unique point numerical value, data accurately can be provided for test.
A kind of Closely locking nut pretightening force measuring apparatus, this device is primarily of upper grip, transmission rod one, holder one, upper cushion block, plug, lower cushion block, holder two, transmission rod two, lower chuck composition.Upper grip is arranged on whole device the top.Transmission rod one is positioned at upper grip lower position, is arranged on centre position, holder one upper end, is bolted to connection.The orthogonal framed structure of described holder one; Upper cushion block is arranged on centre position, holder one lower end; Plug is arranged in the middle of cushion block and lower cushion block, cushion block and lower cushion block in connection; Described lower cushion block is arranged on centre position, holder two upper end and is symmetrical arranged with upper cushion block.Holder two is arranged on below holder one, and holder one and holder about two are existed side by side and to be arranged and shape is identical.Transmission rod two is arranged on centre position, holder two lower end, is also bolted to connection.Lower chuck is arranged on whole device bottom.
The utility model pretightening force measuring apparatus is when carrying out pretightning force and measuring, in nut pretension process, by the sensor feedback on testing machine on computing machine, and reflect the power situation of change of pretension process in real time with figure and unique point numerical value, data accurately can be provided for test.Ensure the research and development quality of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model Closely locking nut pretightening force measuring apparatus.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of Closely locking nut pretightening force measuring apparatus as shown in Figure 1, this device forms primarily of upper grip 1, transmission rod 1, holder 1, upper cushion block 4, plug 5, lower cushion block 6, holder 27, transmission rod 28, lower chuck 9.Upper grip 1 is arranged on whole device the top.Transmission rod 1 is positioned at upper grip 1 lower position, is arranged on centre position, holder 1 upper end, is bolted to connection.The orthogonal framed structure of described holder 1; Upper cushion block 6 is arranged on centre position, holder 1 lower end; It is middle with lower cushion block 6 that plug 5 is arranged on cushion block 4, cushion block 4 and lower cushion block 6 in connection; Described lower cushion block 6 is arranged on centre position, holder 27 upper end and is symmetrical arranged with upper cushion block 4.Holder 27 is arranged on below holder 1, and holder 1 and holder about 27 are existed side by side and to be arranged and shape is identical.Transmission rod 28 is arranged on centre position, holder 27 lower end, is also bolted to connection.Lower chuck 9 is arranged on whole device bottom and is connected with sensor.
During work: be connected with upper grip 1 by transmission rod 1, transmission rod 28 is connected with lower chuck 9.Transmission rod 1, transmission rod 28 by bolt be connected with 2 holders respectively, make it relative displacement to occur in experimentation, plug 5 and Closely locking nut installed.When Closely locking nut is subject to twisting power, owing to there is relative displacement between test unit and lower chuck 9, make the sensor generated data signal be connected with lower chuck 9, by the sensor feedback that is connected with lower chuck 9 on computing machine, and reflect the power situation of change of rundown process with figure and unique point numerical value in real time, and the pretightning force numerical value in this process of accurate recording.In this course, the pretightning force change procedure of computing machine real time record, and with in this process of coordinate diagram form record pretightning force change numerical value.
In order to ensure the reliability of this pretightening force measuring apparatus, to the starting material of vital part in device and the property indices that will reach, all make concrete requirement.Be mainly:
1, transmission rod adopts 30CrMnSiA, and thermal treatment reaches 44-48HRC;
2, holder adopts 30CrMnSiA, and thermal treatment reaches 44-48HRC;
3, backing plate adopts Cr12MoV, and thermal treatment reaches 56-60HRC, both ends of the surface roughness Ra 0.8;
The utility model pretightening force measuring apparatus is when carrying out pretightning force and measuring, in nut pretension process, by the sensor feedback on testing machine on computing machine, and reflect the power situation of change of pretension process in real time with figure and unique point numerical value, data accurately can be provided for test.Ensure the research and development quality of product.
