Description
Technical field:
The utility model relates to a kind of locating device that detects the worm and gear accuracy of mesh.
Background technology:
In mechanical component, crudy is the important assurance that guarantees worm and gear transmitting accuracy, stationarity, rotational noise.The precision of general measure worm and gear needs the detecting instrument of configure dedicated, but does not have the accuracy of mesh that suitable surveying instrument detects little modulus worm and gear in the market.
Summary of the invention:
For overcoming the defective of prior art; The purpose of the utility model is to provide a kind of locating device that detects the worm and gear accuracy of mesh; Be used on parallel-axes gears engagement appearance; Do not change the structure of original gearing mesh appearance, load onto the utility model device, can make the gearing mesh appearance possess the function that detects the worm and gear accuracy of mesh.
The utility model technical solution problem adopts following technical scheme:
Detect the locating device of the worm and gear accuracy of mesh, comprising:
Support, the rear end of said support are provided with the U type groove that is used for the clamping of gearing mesh appearance column, are provided with trip bolt in the two side of said U type groove;
The front end of said support is provided with cross bar, is provided with horizontal V-type groove at the front end face of said cross bar, and the rear end face of cross bar is provided with the kidney slot that connects with said V-type groove;
In said V-type groove, be provided with two columnar first dead heads and second dead head; Be provided with radial screw bore with said kidney slot corresponding position on each dead head, the rear end face of said cross bar be provided with pass said kidney slot and with the dog screw of the threaded hole coupling of dead head;
In said first dead head, second dead head coaxial respectively be provided with first top and second top; Two top middle parts are relatively most advanced and sophisticated with the axial bore clearance fit of its dead head and two top front portions separately; Be provided with handwheel in the said first top rear end, front end is provided with and the first top parallel driving lever, on two dead heads, radially be provided with separately two top lock-screws that carry out axial location;
The middle part of said support is provided with through hole longitudinally, and gear spindle passes said through hole and said cross bar forms decussate texture, is provided with two set nuts on the gear spindle below reaching above the said through hole.
Compared with present technology, the beneficial effect of the utility model is embodied in:
When the utility model device and gearing mesh appearance are used; Be applicable to the worm and gear accuracy of mesh is detected; On the basis that does not change original gearing mesh appearance; Cooperate this device to have the function that the worm and gear accuracy of mesh is measured, have convenient and practical characteristics, need not to buy special-purpose surveying instrument.
Description of drawings:
Fig. 1 is the three-dimensional structure diagram of the utility model; Fig. 2 is the vertical view of the utility model; Fig. 3 is the user mode stereographic map of the utility model.
Label among the figure: 1 support, 2 trip bolts, 3 cross bars, 4 first dead heads, 41 first is top, 411 handwheels, 412 driving levers, 5 second dead heads, 51 second is top, 6 dog screws, 7 lock-screws, 8 gear spindles, 9 set nuts.
Below pass through embodiment, and combine accompanying drawing that the utility model is described further.
Embodiment:
Embodiment: referring to 1,2, the locating device of present embodiment, mate gear engagement appearance can be used for detecting the worm and gear accuracy of mesh, and this locating device comprises:
Coaxially respectively in first dead head 4, second dead head 5 be provided with first top 41 and second top 51; Two top middle parts are round bar; Two top round bar and axial bore clearance fit of its dead head separately; And two top front portions is relatively most advanced and sophisticated, is provided with handwheel 411 in first top 41 rear end, front end is provided with and the first top parallel driving lever 412, and handwheel is used to rotate first top 41; Driving lever 412 is used to stir and is installed in two worm screws between top, radially being provided with two top lock-screws 7 that carry out axial location along dead head separately on two dead heads.
The middle part of support 1 is provided with through hole longitudinally, and gear spindle 8 passes through hole and cross bar 3 forms decussate texture, is provided with two set nuts 9 on the gear spindle 8 below reaching above the through hole.
Referring to Fig. 3, during use, with the center pit of gear spindle 8 upper and lower end faces and a pair of vertical top clamping of gearing mesh appearance; Worm screw to be measured be contained in first top 41 and second top 51 relative two 60 degree top between, regulate the position of two dead heads, make worm screw central longitudinal to be measured to centering be contained in the gearing mesh appearance another to worm gear in vertically top; With fixing respectively two dead heads of two dog screws 6; Regulate two set nuts 9, drive support 1 and move up and down, make worm screw to be measured align the worm gear center up and down; And with two locking set nut 9 lock bracket upper-lower positions, two trip bolts 2 are fixing on the column of gearing mesh appearance with support again.Carrier wheel engagement appearance column makes the worm and wheel flank not have the gap.Rotate handwheel 411, driving lever 412 is stirred the quarter butt of vertical socket on the worm screw and is driven worm screw and rotates, and worm and wheel does not have the gap engagement, is reflected in the data at known gearing mesh appearance indication position, is exactly the meshing error of worm and wheel.
