Embodiment
The pick-up unit of a kind of brake disc wheel hub composition surface flatness as shown in Fig. 1 ~ 2, comprise the base 1 of lower surface and brake disc wheel hub 9 abutting joint face, in measurement, base 1 is placed on to be measured of brake disc wheel hub 9, need to fit than more completely, otherwise can measuring error be there is.Measurement mechanism base 1 being provided with guide piece and being connected with guide piece, base 1 radially offers the first chute 11, base 1 is also provided with hand 6, and hand mainly facilitates carrying and the use of this pick-up unit 6.
Guide piece comprises the slide block 4 that slip is arranged at base 1 upper surface, and slide block 4 end is connected with table folder 2.Need measurement mechanism to slide on to be measured of brake disc wheel hub 9 in actual measurement, therefore need guide piece to drive measurement mechanism to slide, to measure the flatness on two sides to be measured along fixing path.
Guide piece also comprises orienting lug 5, orienting lug 5 is provided with gathering sill 13, and slide block 4 is slidably connected in gathering sill 13.
Orienting lug 5 upper surface is provided with the second chute 12 be communicated with gathering sill 13 in addition, and one end that slide block 4 is positioned at gathering sill 13 is provided with handle 7 connected vertically with it, and handle 7 is slidably arranged in the second chute 12.Orienting lug 5 can be driven to slide by driving handle 7 like this, orienting lug 5 promotes slide block 4, and slide block 4 completes measuring process by promoting measurement mechanism.
Measurement mechanism comprises lower slide and is connected to the measuring staff 8 on brake disc wheel hub 9 composition surface and shows the display device of discrepancy in elevation change in measuring staff 8 sliding process.Measuring staff 8 slides on to be measured of brake disc wheel hub 9, and when to be measured rough time, measuring staff 8 there will be along with rough surface undulation, and this state by display device record out, react and record the flatness of tested surface by word.
Measuring staff 8 is fixed on the end of slide block 4 by table folder 2, and display device is connected with measuring staff 8.In practical application, display device can use a lot of measuring apparatus to replace, and such as uses clock gauge 10 to be used as reacting the device of measuring staff 8 undulating state.
Measuring staff 8 slides on tested surface, the pointer on clock gauge 10 can know reflect efficiently this measuring staff 8 rise and fall degree, as shown in Figure 1, under normal circumstances, namely tested surface be completely surface level time, pointed 0; When measuring staff 8 declines, pointer turns clockwise; When measuring staff 8 rises, pointer is rotated counterclockwise.In measuring process, only need full-scale reading and the least count of record pointer, utilize formula can calculate the flatness of tested surface.
Actual when using, measuring staff 8 arbitrarily can not be slided on tested surface, need to ensure that measuring staff 8 slides in a suitable scope, therefore need to limit radially sliding of handle 7 on slide block 4.As shown in Figure 2, slide block 4 is provided with the screw of through slide block 4, screw inside spin is connected with screw rod 3, by the scope of activities regulating the distance between the screw rod 3 of both sides to limit handle 7, can limit out the moving range of measuring staff 8 like this.
By the setting of screw rod 3, measuring staff 8 can be made closely to move in a limited scope, the precision of measurement tested surface flatness among a small circle in can be improved.
During use, base 1 is placed on brake disc wheel hub 9 composition surface 6 by hand, lay smooth after, installation and guide device and measurement mechanism, need to turn screw rod 3 by straight screwdriver and regulate measurement range before using.
Driving handle 7 makes measuring staff 8 along slide, and the change of record clock gauge 10 pointer, the full-scale reading of record pointer deflection and least count, utilize formulae discovery flatness, complete measurement.
The utility model structure is simple, easy and simple to handle, can be widely used in the detection of the flatness of the brake disc part of all size, have great promotional value.
