Abstract
The invention relates to a device for measuring the symmetry degree of a motor spindle key slot. According to the technical solution provided by the invention, the device for measuring the symmetry degree of a motor spindle key slot comprises an inner measuring claw and an outer measuring claw arranged in parallel on an inner side and an outer side of a bent measuring tool chassis top end at intervals, a measuring snap gauge is further arranged at the measuring tool chassis top end, a plane formed by a straight line on which the inner measuring claw is placed and a straight line on which the outer measuring claw is placed is parallel to a plane in which the measuring snap gauge is placed, a locating screw and a measuring meter are arranged on the measuring tool chassis, a contact of the measuring meter and the locating screw extend in parallel in the same direction, a fastening screw is further arranged on the measuring tool chassis, and the fastening screw and the locating screw are vertically arranged. When in use, the invention largely saves the measuring time, improves the production efficiency and makes each measuring process simple, clear and direct.
Description
Technical field
The present invention relates to a kind of instrument that is used for the measurement of machine shaft keyway symmetry.
Background technology
At present, in producing the machine shaft process,, originally be with general gage measuring to the measurement of machine shaft keyway symmetry always, and rotating shaft to be placed on the two contour v blocks earlier when measuring, v block will place on the flat board, will fill in standard gauge block in advance in the rotating shaft keyway, by repeatedly measurements and calculations indirectly, just can draw end product, measuring process is loaded down with trivial details, and each the measurement approximately needs about 10～15 minutes, and this efficient for producing in batches is too low really.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of and can save detection time greatly, enhance productivity, make each measuring process simple, understand, machine shaft keyway symmetry measuring instrument intuitively.
According to technical scheme provided by the invention, described machine shaft keyway symmetry measuring instrument, it is included in interior measuring claw and the external pelivimetry pawl that outside spaced and parallel is provided with in the measurer frame top of bending, also be provided with the measurement clamp on measurer frame top, plane that interior measuring claw place straight line and external pelivimetry pawl place straight line form and measurement clamp place plane parallel, on the measurer frame, be provided with dog screw and meter, the contact of described meter and dog screw cocurrent and parallel stretch out, also be provided with trip bolt on the measurer frame, described trip bolt is vertical with dog screw to be provided with.
When the present invention measures, greatly saving detection time, improved production efficiency, make each measuring process simple, understand, directly perceived.
Description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is a left view of the present invention.
Fig. 3 is a upward view of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: the present invention mainly is made up of measurer frame 1, trip bolt 2, meter 3, dog screw 4, interior measuring claw 5, external pelivimetry pawl 6 and measurement clamp 7 etc.
This machine shaft keyway symmetry measuring instrument, it is included in the interior measuring claw 5 and external pelivimetry pawl 6 that outside spaced and parallel is provided with in measurer frame 1 top of bending, also be provided with measurement clamp 7 on measurer frame 1 top, interior measuring claw 5 place straight lines are parallel with measurement plane 7, clamp place with the plane that external pelivimetry pawl 6 place straight lines form, on measurer frame 1, be provided with dog screw 4 and meter 3, the contact of described meter 3 and dog screw 4 cocurrent and parallels stretch out, on measurer frame 1, also be provided with trip bolt 2, described trip bolt 2 and dog screw 4 vertical settings.
The present invention mainly adopts interior measuring claw on the measurer frame 15 and external pelivimetry pawl 6 two locating detents is abutted against rotating shaft keyway one side, measure clamp 7 and be close to bottom land, three-point fix is in keyway, regulate special-purpose dog screw 4, make its contact rotating shaft appearance, the position at the rotating shaft center on the upper side, regulate percentage meter 3 then, meter 3 contacts are touched in rotating shaft cylindrical center, screw trip bolt 2, in order to fixation measuring table 3, flicking measuring 1 lower end, see that meter 3 indicating values change, and can read the indicating value data.Measurer frame 1 is turned over 180 °, and the interior measuring claw on 15 on the measuring is close on the rotating shaft keyway another side with external pelivimetry pawl 6 two locating detents, measure clamp 7 and still be close to bottom land, read scale indicating value data with above identical measuring method, poor with twice indicating value data, by special-purpose formula: f=axt/ (R-t/2), calculating can draw rotating shaft keyway symmetry end product.
Wherein, a-difference of reading; The t-groove depth; R-rotating shaft radius.
