On face, splicing sleeve is fixed on the base, screw rod set is directly anchored on splicing sleeve, and two dial gauges are adsorbed on ball screw two
On side, ball screw and the load of hydraulic loaded instrument are connected, and hydraulic loaded instrument jacks up ball screw, and the reading of two dial gauges is added
Divided by, as ball screw and screw rod set axial gap amount, can preferably simulate ball screw and screw rod set assembly
State, and the axial gap that can be precisely calculated very much between ball screw and screw rod set, enable and install ball screw additional
Enough guarantee design requirement, the utility model can be used for the axial gap of measure-ball screw rod and screw rod set.
The dial gauge is arranged on ball screw through Magnetic gauge stand as a further improvement of the utility model, in this way
Dial gauge can be fixed on ball screw well, and also easily move and adjust dial gauge on ball screw
Position enables dial gauge to measure axial gap.
The dial gauge is symmetricly set on ball screw two sides, such ability as a further improvement of the utility model,
Ensure the two edge error very little of degree measured, so that the axial gap finally measured is more accurate.
It is mating on the hydraulic loaded instrument as a further improvement of the utility model, to be provided with adjusting set, the bulb
Screw rod is connected through adjusting set with hydraulic loaded instrument, can replace tune adaptable therewith according to the length of ball screw in this way
Section set, enables hydraulic loaded instrument to act on the ball screw of different size model.
The splicing sleeve and screw rod set in this way may be used on same central axis as a further improvement of the utility model,
To ensure the stability of the whole device in measurement process, so that the precision of measurement data is higher.
The screw rod set is fixedly connected through bolt one and is arranged on splicing sleeve as a further improvement of the utility model,
It can make to connect between screw rod set and splicing sleeve so more stable and easy to disassemble.
The splicing sleeve is fixedly connected through bolt two and is set on the base as a further improvement of the utility model, this
Sample can to connect between screw rod set and splicing sleeve more stable and easy to disassemble.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Wherein, 1 ball screw, 2 Magnetic gauge stands, 3 dial gauges, 4 screw rod sets, 5 splicing sleeves, 6 pedestals, 7 bolts one, 8 bolts
Two, 9 adjusting sets, 10 hydraulic loaded instrument.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing:
The detection device of a kind of measure-ball screw rod as shown in Figure 1 and screw rod set axial gap, including ball screw 1,
Ball screw 1 is connected with screw rod set 4, it is characterised in that: the screw rod set 4 is arranged on splicing sleeve 5, and splicing sleeve 5 is fixed on bottom
On seat 6, hydraulic loaded instrument 10 is provided on pedestal 6, hydraulic loaded instrument 10 is connected with ball screw 1,1 two sides of ball screw difference
It is provided with a dial gauge 3, the measuring head of dial gauge 3 is contacted with screw rod set 4；Dial gauge 3 is arranged through Magnetic gauge stand 2 in bulb spiral shell
On bar 1；Dial gauge 3 is symmetricly set on 1 two sides of ball screw；It is mating on hydraulic loaded instrument 10 to be provided with adjusting set 9, ball screw
1 is connected through adjusting set 9 with hydraulic loaded instrument 10；Splicing sleeve 5 and screw rod set 4 are on same central axis；Screw rod set 4 is through bolt one
7 are fixedly connected with setting on splicing sleeve 5；Splicing sleeve 5 is fixedly connected through bolt 28 to be arranged on pedestal 6.
When work, by the way that hydraulic loaded instrument 10 to be placed in 6 plane of pedestal, according to the threaded hole of different screw rod sets 4
Away from matching a kind of splicing sleeve 5 surely and splicing sleeve 5 being fixed on pedestal 6, screw rod set 4 is directly anchored to prop up by bolt 1 at center
