Description
Technical field
The utility model relates to the linear measure longimetry field, specifically, relates to the measurement aid that a kind of micrometer inside caliper is used.
Background technology
Industrial, in order to guarantee the accurate assembling of equipment axis and bearing, the corresponding measurer of a cover and equipment axis and bearing need be arranged.Usually, the survey instrument of the external diameter of measuring equipment axle has outside micrometer, and the survey instrument of measurement bearing bore diameter (being the diameter of bearing Neva) has micrometer inside caliper.By being used of outside micrometer and micrometer inside caliper, the accurate internal diameter of the external diameter of measuring equipment axle and the bearing corresponding with this equipment axis, thus guarantee to find for equipment axis the bearing of accurate coupling.
But micrometer inside caliper and outside micrometer all are the precision measurement instruments, and price is very high.Especially for the milscale of measuring major diameter equipment axis and bearing thereof, very expensive especially, and also operation is not too convenient at the construction field (site).Therefore, if can use the few milscale but be equipped with of trying one's best measure aid finish in the surveying work of external diameter, so can be very helpful for saving cost and increasing work efficiency.
The utility model content
The utility model is made for solving the problems of the technologies described above, the measurement aid that provides a kind of micrometer inside caliper to use is provided its purpose, in order to only do not use under the situation of micrometer inside caliper not using outside micrometer, external diameter that still can the measuring equipment axle.
To achieve these goals, the measurement aid that the utility model provides a kind of micrometer inside caliper to use, it comprises: arched arm, fixedly there is the pair of plates that is parallel to each other at the two ends of this arched arm, and a flat board in this pair of plates is provided with tapped hole; The screw push rod, the tapped hole engagement of this screw push rod and a described flat board; Movable plate, this movable plate are fixed on an end of described screw push rod, and this movable plate is between the described pair of plates on the described arched arm and be parallel to this to flat board.
Preferably, described arched arm can cut out from steel plate, described pair of plates and described movable plate can be made by steel plate, and described pair of plates can be fixed by welding in the two ends of described arched arm, and described movable plate can be fixed by welding in an end of described screw push rod.
When using the external diameter of micrometer inside caliper and measurement aid measuring equipment axle described in the utility model, earlier equipment axis is placed between the pair of plates of described arched arm, and make the outside surface that does not touch equipment axis in this pair of plates with the flat board of screw push rod engagement.Then, the rotary screw push rod contacts described movable plate at leisure with the outside surface of equipment axis.When movable plate contacts gently with the outside surface of equipment axis, described measurement aid is taken off on equipment axis gently.Then, measure in the described pair of plates not and the flat board of screw push rod engagement and the distance between the movable plate with micrometer inside caliper, then this distance is the external diameter of described equipment axis.Behind the external diameter of measuring equipment axis, can measure the internal diameter of different bearings with micrometer inside caliper, to find the bearing that accurately mates with this equipment axis.
From top description and the practice as can be known, only do not use under the situation of micrometer inside caliper not using outside micrometer, by using measurement aid described in the utility model, the external diameter of the enough micrometer inside caliper measuring equipment axles of energy, thereby effectively reduce production costs, be convenient to execute-in-place simultaneously.

Embodiment
An embodiment of the measurement aid that micrometer inside caliper described in the utility model uses is described below with reference to the accompanying drawings.Those of ordinary skill in the art can recognize, under the situation that does not depart from spirit and scope of the present utility model, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used for the protection domain of restriction claim.In addition, in this manual, identical Reference numeral is represented same or analogous part.
Fig. 1 is front elevational schematic, shows the structure of the measurement aid that a described micrometer inside caliper of embodiment of the present utility model uses.
As shown in Figure 1, the measurement aid 100 used of a described micrometer inside caliper of embodiment of the present utility model comprises: arched arm 11, screw push rod 12 and movable plate 13.
Fixedly there is the pair of plates that is parallel to each other at the two ends of arched arm 11, i.e. the first dull and stereotyped 11a and the second dull and stereotyped 11b, and a flat board in this pair of plates (for example first dull and stereotyped 11b) is provided with tapped hole.
Screw push rod 12 meshes with the tapped hole of a described flat board (i.e. the first dull and stereotyped 11b).
Preferably, arched arm 11 can cut out from steel plate, the first dull and stereotyped 11a, the second dull and stereotyped 11b and movable plate 13 can be made by steel plate, the first dull and stereotyped 11a and the second dull and stereotyped 11b can be fixed by welding in the two ends of arched arm 11, and movable plate 13 can be fixed by welding in an end of screw push rod 12.
Fig. 2 is front elevational schematic, shows the use state of the measurement aid 100 that above-mentioned micrometer inside caliper uses; Fig. 3 is front elevational schematic, shows the state that is used of micrometer inside caliper and measurement aid 100 described in the utility model.
When using the external diameter of micrometer inside caliper 300 and above-mentioned measurement aid 100 measuring equipment axles 200, as shown in Figure 2, earlier equipment axis 200 is placed between the first dull and stereotyped 11a and the second dull and stereotyped 11b of arched arm 11, and make the outside surface that does not touch equipment axis 200 in this pair of plates with the flat board (i.e. the first dull and stereotyped 11a) of screw push rod 12 engagements.Then, rotary screw push rod 12 contacts movable plate 13 at leisure with the outside surface of equipment axis 200.When movable plate 13 contacts gently with the outside surface of equipment axis 200, will measure aid 100 and on equipment axis 200, take off gently.Then, as shown in Figure 3, measure in the described pair of plates not and the flat board (i.e. the first dull and stereotyped 11a) of screw push rod engagement and the distance between the movable plate 13 with micrometer inside caliper 300, then this distance is the external diameter of equipment axis 200.Behind the external diameter of measuring equipment axis 200, can measure the internal diameter of different bearing (not shown) with micrometer inside caliper 300, to find the bearing that accurately mates with this equipment axis 200.
