Description
Technical field
The utility model relates to a kind of pick-up unit, especially a kind of magnitude of interference pick-up unit, for checking whether the installation magnitude of interference of joining conduit meets the requirements.
Background technology
Aviation reduction case joining conduit is arranged on engine fuel to be provided on oil circuit, and joining conduit and reduction case belong to interference fit and install.If the mounting hole aperture on casing is in oval or the upper and lower size in aperture is inconsistent, can cause joining conduit and reduction case tolerance clearance overproof.In use procedure, joining conduit fine motion under hydraulic oil effect, tolerance clearance expands further because wearing and tearing, and damage asbestos seal pad, seal failure, lubricating oil leaks outside fast, causes fuel oil after-flame alarm failure.As the joining conduit on certain air line reduction case, require to check whether the magnitude of interference under 450N ~ 500N static pressure meets engine design requirement, namely pulls out joining conduit vertically with the withdrawal force of 450N ~ 500N and checks whether loosening.To the measurement of this index, need a set of stable static pressure force application apparatus with force reading, there is no the measuring mechanism of this type at present.
Summary of the invention
The purpose of this utility model is to provide a kind of pick-up unit, can realize joining conduit and casing and install the magnitude of interference and detect, check whether the magnitude of interference meets engine design requirement under static pressure force state.
Concrete scheme of the present utility model is: magnitude of interference pick-up unit comprises support, force swivel nut, pressure spring, joint sleeve, holding claw, reading plate, quick-release push rod, described support is provided with the force swivel nut of hollow by screw thread, joint sleeve is through in the middle of force swivel nut, one end and uniting conduit minor diameter fit are also provided with at least two uniform holding claws by hinge joint mode, the end of described holding claw is provided with the claw of the seal groove that can be stuck in uniting conduit, the other end of joint sleeve is provided with screw thread and is provided with stop nut, pressure spring is provided with between stop nut and force swivel nut, described support 5 is provided with the reading dial of mark force swivel nut position.The inside of described joint sleeve is cavity structure and is provided with quick-release push rod, described holding claw is provided with extension relative to the other end of claw and puts in the internal cavities of joint sleeve, quick-release push rod one end withstands on the extension of holding claw, and the other end extends to the outside of joint sleeve.Magnitude of interference pick-up unit also comprises the seal groove force application structure of the claw close fit engagement conduit making holding claw, described force application structure is the fastening swivel nut being arranged on joint sleeve, described fastening swivel nut inside is provided with the screw thread and inner conical surface that are connected with joint sleeve, and the outside surface of holding claw is taper and coordinates with the inner conical surface of fastening swivel nut; Described force application structure for be provided with ring groove on holding claw external diameter, described ring groove can also be provided with coil spring.Described holding claw is uniform four.
Support operationally, is fixed on casing by the utility model, the end of joint sleeve and joining conduit minor diameter fit, draw holding claw in, claw in holding claw is coordinated with the seal groove of joining conduit, holds joining conduit tightly, under the effect of pressure spring, axial force is applied to joining conduit, by the position of adjustment force swivel nut, the value of thrust to joining conduit can be adjusted, the conduction of the pulling force of regulation is applied to joining conduit, reach force inspection requirements, check whether joining conduit loosens or be pulled out.Meanwhile, after measurement terminates, by pressing the mode of quick-release push rod, holding claw can be opened, realizing the object of quick-release.Whether the utility model not only can be measured the magnitude of interference easily and meet the demands, and has simple to operation, service-strong advantage, lever principle can also be utilized, holding claw is pushed to carry out quick-detachment to pressing down quick-release push rod, flexible, convenient, handy, achieve fast-assembling, quick-detachment function requirement.
Simultaneously, as another function of the present utility model, by improving the pretension force value of pressure spring, or directly to the stop nut in upper stretching structure, the joining conduit installed by interference can also be dismantled without the carrying out of destroying, there is the advantages such as simple, effective, cost-saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
