Specific implementation mode
The utility model is below with reference to embodiment(Attached drawing)It is further described:
As shown in Figure 1, 2, the measurement Gear Root residual stress angle regulator of the utility model includes that setting is installed Rotary shaft 1 in support base 13 is mounted on two support bases 2 and an angle tune at 1 top of rotary shaft in cantilever fashion Save seat 3, the horizontal overhanging end of two support bases 2 installed in a manner of being vertically arranged respectively there are one upper end take the shape of the letter U fork structure Supporting rod 9, be connected with intermediate connecting part by horizontally disposed shaft 7 in 9 upper end of supporting rod, the intermediate connecting part It is made of the connection axillare 8 being combined with shaft 7 being vertically arranged, the terminal pad 5 being fixed at the top of connection axillare 8(Referring to Fig. 3);Top is provided with the angle of idler wheel 11 there are one being installed in a manner of being vertically arranged in the horizontal overhanging end of angular adjustment seat 3 Adjusting rod 4 is spent, angle index is marked in angular adjustment bar 4(The correspondence of H and θ are found out by H=L*tan θ-r* (1/cos θ -1) Relationship marks on adjusting rod);It is placed with carrying disk 6 at the terminal pad 5,11 top of idler wheel;The terminal pad 5 Top surface is combined by connector with 6 bottom surface of carrying disk, and the idler wheel 11 and the radial guide groove of 6 bottom surface of carrying disk setting match It closes;Plane is provided with protractor on the carrying disk 6, is equipped at planar central position for putting on the carrying disk 6 Set the loading shallow bid 14 and clamping device of workpiece.
The mode that rotary shaft 1 described in the utility model is connected through a screw thread is together with 13 spinning of support base;Two Support base 2 and an angular adjustment seat 3 are fixed on 1 top of rotary shaft in such a way that angle is in 120 ° of arrangements by nut;It is described Angular adjustment bar 4 is installed on vertically in the through-hole that 3 horizontal overhanging end of angular adjustment seat processes, and the jackscrew being arranged by side Realize the altitude location of angular adjustment bar 4.
13 bottom surface of the support base for playing support whole device in the utility model is horizontal plane structure(In high precision Plane), to ensure the levelness of whole device;The supporting rod 9 is combined with support base 2 threadably.
Adjusting rod length transition is to adjust the device of angle, including measurement, carrying disk are by tri-point support by the utility model (It is made of two supporting rods, 9 one angular adjustment bars 4), it is the tangent several of easy observation that will visually be difficult to the horizontal adjustment observed What relationship, the correspondence that H and θ are found out by H=L*tan θ-r* (1/cos θ -1), according to the formula derived, in angle tune Corresponding scale is indicated on pole, the angle for being not easy to measure is become into the tangent geometrical relationship for being easy to observe, by allowing Sample directly reads angle after moving back and forth determining tangent relation.
Rotary shaft 1 can be also combined by bearing with support base 13 by the utility model, can add a direct current in lower section Motor(DC speed-reducing)And transmission device, it is input in rotary shaft after adjusting rotating speed, carrying disk is allow to rotate.
It the shortcomings that balance bad regulation and control when the utility model will use plasticine to fix gear in the prior art, is changed to answer The angle for needing to adjust is measured with measuring device tangential manner, then adjusts angle with angle regulator, finally with clamping dress It sets and steps up to fix.
More specifically:One end of two support bases 2 and an angular adjustment seat 3 is fixed on by nut in rotary shaft 1, and three 120 ° of angles are mutually between person two-by-two, the terminal pad 5 and carrying disk 6 for forming intermediate connecting part are connected by screw, angle tune The idler wheel 11 of 4 upper end of pole can slidably reciprocate in the slot of carrying disk lower surface, and angle measurement unit passes through on carrying disk Fix a protractor perpendicular to carrying disk plane(Such as Fig. 4), protractor and carrying disk upper surface are tangent, and experiment material can be with Move back and forth on carrying disk, adjusts position, when the circular arc for testing gear material tooth root is tangent with a certain angle line of protractor, The angle is that carrying disk needs the angle, θ adjusted, then adjusts angle by angular adjustment bar, angle regulator can simplify For with drag, three points support carrying disk, two points are fixed, and angular adjustment bar can move up and down to adjustment angle Degree, three points constitute an isosceles triangle, and two fixing points are connected as the bottom edge of isosceles triangle, three supporting rods(Two Support base 2 and an angular adjustment seat 3)Between each other 120 ° two-by-two, if a height of L of the isosceles triangle, then angular adjustment bar Adjusting height H=tan θ * L from horizontal position(Carrying disk is horizontal when H=0), it is contemplated that adjusting rod is rolled in slot by idler wheel Come what is realized, supporting point can change, if radius of roller is r, above formula should be adjusted to H=L*tan θ-r* (1/cos θ -1), lead to The correspondence that H=L*tan θ-r* (1/cos θ -1) find out H and θ is crossed, is marked on adjusting rod.
When experiment, first experiment material used(Gear Root)It is placed on carrying disk and finds position back and forth, waiting is found When a certain angle of protractor is tangent with tooth root circular arc, the angle is read, as adjusting rod needs the angle adjusted, then by angle tune Pole 4 adjusts angle, and angular adjustment bar 4 may be implemented quickly to adjust.Gear Root should be placed on clamping dress after measuring angle It sets on 10, clamping device is made of two vertical planes and some trip bolts, and experiment material is close to two vertical planes It places, since external force can be ignored in measurement process, therefore only needing low-force to act on sample not makes its change in location, Several using trip bolt, its right side is fixed by trip bolt after measurement angle, and fastening force is smaller here, does not influence test knot Fruit.
