Abstract
The utility model relates to an adjustable excircle caliper gauge, which comprises a main clamp pin and an auxiliary clamp pin. The top of the main clamp pin is extended towards one side to be provided with a cross beam, the top of the auxiliary clamp pin is protruded outwards to form an upper chute and a lower chute, the cross beam is arranged in the chutes, the auxiliary clamp pin can slide along the cross beam, and a reference slot formed in the middle of one side of the blade of the auxiliary clamp pin through grinding. The utility model has a simple structure, and can adapt to measurement requirements for various specifications through adjusting the positions of the main clamp pin and the auxiliary clamp pin. Moreover, the blade can be ground so as to conveniently restore the size range to be measured, thereby prolonging the service life of the caliper gauge and effectively saving the production cost.
Description
Technical field
The utility model relates to a kind of survey instrument, is meant a kind of adjustable cylindrical calliper specifically.
Background technology
In the commercial production, need measure the part of being produced usually and determine whether it is qualified.When the axial workpiece of being produced is detected, to use a kind of instrument usually---calliper detects whether conformance with standard of its external diameter.The existing calliper that is used for measurement axis class external diameter specially has two measuring junctions usually, defined the limit of standard up and down up to specification respectively, and the workman uses for convenience, this class calliper all is that the special die sinking of a certain regulation is produced, so just make calliper in case the wearing and tearing back its repair difficulty just very big in addition just in case wearing and tearing just can't repair.Particularly concerning the very strict part of some accuracy requirements, the error that it was suitable for is very little, has to 0.001 millimeter even littler stage, well imagines so, the calliper that it was suitable for just can't reuse in a little wearing and tearing back, has so just increased production cost.
The utility model content
The purpose of this utility model is to provide a kind of adjustable cylindrical calliper, and it is simple in structure, and repairs easily, can use repeatedly, effectively reduces production cost.
For achieving the above object, the utility model adopts following technical scheme:
A kind of adjustable cylindrical calliper is characterized in that: described calliper is made up of main card pin and secondary card base, and both cutting edge one sides are oppositely arranged; The top of described main card pin is extended to a side and is provided with a crossbeam, the top of affiliated secondary card base outwards convex to form twice chute up and down, described crossbeam is arranged in the described chute, and described secondary card base can slide along described crossbeam; Cutting edge one middle side part of described secondary card base grinds out a baseline trough; The top of described secondary card base, the top of upper hopper chute are provided with an adjustable screw thread snap close.
The following corner of described secondary card base is provided with a pressing board.
Can promote secondary card base with pressing board and slidably reciprocate, when secondary card base both moves to allocation, screw the screw thread snap close, just can fix.
Grind the cutting edge portion of main card pin and secondary card base respectively, and make the distance of both cutting edge portions reach both provisioning requests.
For cutting apart, the distance between the two-edged oral area defines the bound of the outside diameter of measurement that requires respectively with baseline trough.
The utility model is simple in structure, and can adapt to the measurement requirement of plurality of specifications by the position of regulating major and minor card base, cooperates the grinding of counter blade oral area can repair the range of size that will measure easily, effectively saves production cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of adjustable cylindrical calliper as shown in Figure 1, form by main card pin 01 and secondary card base 02, the top of main card pin 01 is provided with a crossbeam 11 to side extension, the top of secondary card base 02 outwards convex to form twice chute 21 up and down, crossbeam 11 is arranged in the described chute 21, and secondary card base 02 can slide along crossbeam 11; Cutting edge one middle side part of secondary card base 02 grinds out a baseline trough 24 this cutting edge is divided into two sections: go up cutting edge 25 and following cutting edge 26.
The top of secondary card base 02 is provided with an adjustable screw thread snap close 22, and rotating latch 22 can be regulated the degree of tightness that secondary card base 02 is connected with crossbeam 11.
The following corner of secondary card base 02 is provided with a pressing board 23.
Promote secondary card base 02 with pressing board 23 and slidably reciprocate, directly contact the generation that causes situations such as getting rusty thereby can prevent to point with card base.When secondary card base 02 both moves to allocation, screw screw thread snap close 22, just can fix.
With baseline trough 24 is cut-point, the bound that the last cutting edge portion 25 of the cutting edge portion 12 of main card pin and secondary card base and following cutting edge portion 26 direct positions have just determined measured outside diameter.
The utility model is simple in structure, and can adapt to the measurement requirement of plurality of specifications by the position of regulating major and minor card base, cooperate the grinding of counter blade oral area can repair the range of size that to measure easily, prolonged the serviceable life of calliper, effectively save production cost.
