Abstract
The invention discloses a bearing pedestal starting moment measuring apparatus which is characterized by comprising a measuring rod with a lever structure. A middle part of the measuring rod is connected with a rotating shaft through a deep groove ball bearing. A rotation center of the rotating shaft is a lever fulcrum. A front end of the measuring rod is a lever acting force point and is set as a measuring head which can be driven by a transition rod. A tail of the measuring rod is a lever resistance point and is provided with a pressure sensor at a corresponding position. The pressure sensor measures a pressure value of a lever resistance point position. When turning the measuring head through the transition rod, the measuring head drives the measuring rod to rotate around the rotating shaft, the pressure sensor detects the pressure value at the tail of the measuring rod, and when a lever moment arm is fixed, starting moment is calculated according to the measured pressure value and the moment arm. When press mounting of a main cone bearing is completed, measurement of bearing pedestal starting moment can be carried out, a feedback time is short, assembling efficiency can be greatly raised, and measurement accuracy is raised.
Description
Technical field
The present invention relates to be applied in the automobile assembling industry device that main cone bearing seat staring torque is measured.
Background technology
In automobile assembling industry; Prior art generally is being the prosecutor face to realize through following manner to main cone bottom bracket staring torque: when accomplishing the assembling of main cone bearing inner race; Field worker rotates main cone with instrument; Judge by rule of thumb whether the main cone staring torque is qualified, in claimed range, which link existing problem it is to the staring torque that when dispatching from the factory, detects automobile again for the substandard product analysis.A kind of like this mode of operation feedback time is long, and the experience of field worker directly influences testing result, and efficiency of assembling receives great influence.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of bearing seat staring torque measurement mechanism is provided, to shorten feedback time, improve efficiency of assembling, and accuracy being measured in raising.
The present invention adopts following technical scheme for the technical solution problem:
The design feature of bearing seat staring torque measurement mechanism of the present invention be provided with one have a lever construction measuring staff, said measuring staff is connected with rotating shaft through deep groove ball bearing at the middle part; As balance pivot be the center of rotation of rotating shaft, be set to the measuring head that can drive by transiting rod with the front end of the measuring staff in force as lever; Afterbody correspondence position as the measuring staff of lever resistance point is provided with pressure transducer, records the force value of lever resistance point position with said pressure transducer.
The design feature of bearing seat staring torque measurement mechanism of the present invention also is:
Said measuring head is set to the axial float structure at the measuring staff front end; The front end that said axial float structure is a measuring staff is fixedly connected one section spring core rod; Said measuring head is contained in the rod end of said spring core rod through the gauge head spring housing, forms the axial float structure of measuring head on said spring core rod.
Afterbody at said measuring staff is provided with the swing position limiting structure; Said swing position limiting structure is that afterbody and the measuring staff at said measuring staff is " ten " word one cuphead pilotage is set; One end pin head of said cuphead pilotage is butted on limit base through stage clip; The other end of cuphead pilotage is butted on limited block, and the spacing position of adjustment piece adjustment limited block is arranged, with the swing gap of adjustment measuring staff.
When stirring measuring head by transiting rod, measuring head drives measuring staff and rotates around the axis, and pressure transducer detects force value at the afterbody of measuring staff, in the fixing situation of lever arm of force, can calculate the size of staring torque according to the force value that records and the arm of force.Compared with present technology, beneficial effect of the present invention is embodied in:
The present invention can carry out the measurement of bearing seat staring torque when accomplishing the main cone bearing press mounting, feedback time is short, can greatly improve efficiency of assembling, and improves and measure accuracy.
