Description
[technical field]
The utility model is about a kind of angel measuring instrument.
[background technology]
The axostylus axostyle axis of car transmission shaft is a very important size with the universal joint axis angle, and it has much relations with the machining precision and the process of transmission shaft, wishes that generally this angle is bigger than normal for well.But control was not at that time in the transmission shaft process of manufacture, angle will occur than large deviation, in this normal afterwards use therefore angle do not meet the demands and make the wearing and tearing of transmission shaft rapid abnormal, make transmission shaft occur abnormal sound in advance, bad phenomenon such as leakage of oil are so this size is essential items for inspection for production firm.For applying unit, amateur manufacturer, do not having under the condition of special inspecting equipment, the concrete size of wanting to measure this space angle is difficulty relatively, and this usually needs to utilize three-dimensional and related check accessory equipment, time-consuming when at every turn checking, effort; As under the situation that does not have three-dimensional equipment, also need drop into higher fund and purchase special inspecting equipment and measure.
In reality was produced, the way that the someone utilizes line back, space line to measure was measured, and this method is not only heavy, and the angle of measuring is inaccurate, is prone to misjudgment phenomenon.
The somebody manufactures special-purpose measurement of angle cubing and checks this angle, this cubing generally all is a standard sample Angular Dimension model, lean on the angle of transmission shaft with model during check, see that the gap length of both sides judges whether the angle of transmission shaft is qualified, this kind method of inspection can only judge whether to have reached the regulation requirement, for concrete angle is that how much numerical value can't be measured, this cubing mainly is that range estimation judges whether to meet the requirements simultaneously, the gap size variation is very big when control is improper, and bigger inaccuracy is arranged.
More than these several measuring methods be not that precision is limited, be exactly that input is bigger, for the enterprise that does not need three-dimensional check, or the accidental enterprise that once checks, all be a kind of waste.

[embodiment]
Fig. 1 to Figure 16, the utility model spatial angle measuring instrument is the angle that is used to measure between the axis of the axis of workpiece for measurement fixed part and pivotable parts, in the present embodiment, this spatial angle measuring instrument is used to measure the included angle A between the axis of the ball cage 81 of transmission shaft 8 and transmission shaft axostylus axostyle 82.This spatial angle measuring instrument comprises base 1, flat board 2, keeper 3, surveys rail 4, surveys chi 5, pivot pin 6 and web joint 7.This base 1 is used to support whole measuring instrument.This flat board 2 is a steel plate and the top that is fixed by welding in base 1, and upper surface 21 that should flat board 2 is one to be parallel to the plane of surface level.Keeper 3 is used for fixing the fixed part 82 of workpiece for measurement, it is " V " sections 3, and be fixed on dull and stereotyped 2 upper surface 21 by the mode that is threaded, and the center line that is somebody's turn to do " V " sections 3 is parallel with surface level, in the present embodiment, should have two by " V " sections 3, its spacing is adjusted according to the size of workpiece for measurement.
See also Fig. 4 and Fig. 5, survey rail 4 and have two, it is fixed on the base 1 and symmetry is positioned at transmission shaft 8 both sides.In the vertical direction, each surveys that rail 4 all is positioned at dull and stereotyped 2 below and have certain height with it poor, and this difference in height of surveying between rail 4 and dull and stereotyped 2 should be suitable, and is not enough to prevent surveying big workpiece time space size.This surveys rail 4 is the rectangular steel of square-section, this survey rail 4 axially on milled out first, second orbit measurement slot 41,42, this first, second orbit measurement slot 41,42 vertically passes through mutually, promptly this two orbit measurement slot 41,42 is opened in respectively and surveys on the perpendicular surface of rail two, this first orbit measurement slot 41 is used for inserting survey chi 5 usefulness, second orbit measurement slot 42 is used for inserting pivot pin 6 usefulness, and the dimensional accuracy and the surfaceness of this orbit measurement slot all have higher requirements, survey after guaranteeing chi by pivot pin 6 when mobile therein resistance little and error is little.
See also Fig. 6 and Fig. 7, survey chi 5 and have two, this two surveys chi 5 is parallel to each other and is rectangular plate, milled out along this survey chi 5 axially extended measuing tape slots 51 in the centre position of this survey chi 5, this measuing tape slot 51 is used to insert pivot pin 6, its size is all identical with the size and the dimensional accuracy of second orbit measurement slot 42, and the thickness of this survey chi 5 is as the criterion to insert can easily move and not have to rock in first orbit measurement slot 41.In addition, also can be provided with locating surface on this survey chi 5, this locating surface is used to locate the position of surveying chi and web joint, and should survey chi with web joint between be connected by bolt fastening.The linearity of this survey chi axis direction is had relatively high expectations, with the working face as the usefulness that directly takes measurement of an angle.
See also Figure 11 to Figure 16, the both ends of web joint 7 are surveyed chi 5 and are connected by bolt with two respectively, and this two surveys chi 5 is all vertical with web joint 7.The middle part of this web joint 7 is provided with mating holes 71, this mating holes 71 is used for closely cooperating with the mating surface of transmission shaft ball cage 81, and the parallel axes of the survey chi 5 after the axis of this mating holes 71 and the installation, the included angle B when measuring with assurance between survey chi 5 and the survey rail 4 is the included angle A between ball cage 81 and the axostylus axostyle 82.When pulling web joint 7, just can drive ball cage 81 rotates around the contact point of itself and mating holes 71, web joint 7 drives the survey chi 5 and the pivot pin 6 that are positioned at its two ends simultaneously and moves around at the orbit measurement slot of surveying rail 4, when pulling the angle maximum, survey chi and survey between the rail angle is promptly arranged, this angle is the axis of transmission shaft ball cage and the included angle A between the axostylus axostyle axis, just can be convenient for measuring this angle by an assistant flat-plate and angulometer commonly used.
The process that this spatial angle measuring instrument takes measurement of an angle is as follows: 1) axostylus axostyle 82 with transmission shaft is placed on two " V " sections 3, make transmission shaft ball cage 81 place dull and stereotyped 2 outsides, then web joint 7 is enclosed within on the mating surface of ball cage 81, and mating holes 71 and this mating surface are closely cooperated; 2) compress the axostylus axostyle 82 of transmission shaft with pressing plate 9; 3) pull web joint 7, make the angle maximum between transmission shaft ball cage 81 and the axostylus axostyle 82; 3) take a little assistant flat-plate to be placed on the surface of surveying rail, measure this assistant flat-plate and two angles of surveying between the chi with common inclinometer; 4) mean value of calculating two-sided measurement angle promptly obtains the angle between ball cage 81 and the axostylus axostyle 82.
In the utility model, for different workpieces for measurement, owing to dimensional requirement difference, so need to select different web joints to mating holes.This spatial angle measuring instrument can also be used for measured automobiles and turn to angle between cross bar and the front axle swing arm.
