Abstract
The utility model discloses a caliper for measuring the diameter of an inner groove, which conquers the defect of the existing vernier caliper that measuring feet can't touch the edge of the inner groove, thus the diameter of the inner groove can not be measured. The inner groove measurement caliper comprises a caliper body, two measuring feet, and horizontal measuring heads on the bottoms of the measuring feet and towards the opposite directions, wherein the measuring heads are in parallel with the length direction of the caliper body. The measuring heads are plate shaped, and one ends of the measuring heads far away from the self-connected measuring feet are in the arc shape. The caliper is suitable for occasions of the existing calipers, and the measuring feet extend into the inner groove and then separate, so as to respectively contact with the sides of the inner groove along the diameter direction to smoothly measure the diameter of the inner groove, and the measuring feet are made at the fixed state to facilitate reading and the reading accuracy is ensured.
Description
Technical field
The utility model relates to a kind of survey instrument, relates in particular to a kind of internal channel and measures slide calliper rule.
Background technology
In productive life, often can porosely need to carry out diameter measurement with internal channel such as jump-ring slots.Internal channel is embedded among workpiece, the machine, outside its surface not exclusively is exposed to, if therefore use common vernier caliper, surveys the trough rim that pin can't touch internal channel, can not its true diameter of Measurement accuracy.
China Patent Publication No. CN201463773U, open day on May 12nd, 2010, the name of utility model is called vernier caliper, this application case discloses a kind of vernier caliper, its external pelivimetry pawl measurement face at vernier caliper hard alloy measuring face of burn-oning, or be fixedly connected with wimet in measurement face one side of the external pelivimetry pawl body of steel and measure body, and the surfaceness, flatness and the depth of parallelism that make hard alloy measuring face or wimet measure body are ground to the requirement that meets vertification regulation.This utility model weak point is to survey the trough rim that pin can not touch internal channel, true diameter that can not the Measurement accuracy internal channel.
The utility model content
The trough rim that the survey pin that the utility model has overcome existing vernier caliper can not touch internal channel causes measuring the deficiency of internal channel diameter, and a kind of slide calliper rule that can measure the internal channel diameter are provided.
The utility model is achieved through the following technical solutions:
A kind of internal channel is measured slide calliper rule, comprises blade, two survey pin, and described survey sole end is provided with the gauge head of level, and two gauge heads of surveying the sole ends are towards the opposite, and described gauge head is parallel with the blade length direction.Survey pin and be used for inserting internal channel, internal channel one side is withstood in the gauge head outer end that makes one of them survey the sole end, then can will survey pin separately, another gauge head of surveying sole end level is moved to withstand the internal channel offside, can carry out reading this moment, namely finished the measurement of internal trench diameter.
As preferably, described gauge head is plate shape, and described gauge head is circular arc away from the end with self phase tie-in pin.Gauge head is used for and the internal channel sidewall contact, more fragile, manufactured Board shape can be improved and connected and self intensity, and gauge head is with the sidewall contact of internal channel away from the end with self phase tie-in pin, circular arc can guarantee to be a contact, avoids causing measuring error larger because of the out-of-flatness of gauge head end.
As preferably, one of described two survey pin connect firmly with blade one end, another is surveyed pin and is slidingly connected by vernier sliding sleeve and blade, and described vernier sliding sleeve upper end is provided with the lock-screw that is threaded with the vernier sliding sleeve, and described lock-screw is in the middle part of vernier sliding sleeve.When measuring, the gauge head of the survey sole end that connects firmly with blade can be withstood first a trough rim on the internal channel diametric(al), so another gauge head can not be subject to the external force impact yet and move convenient operation; Then operate the vernier sliding sleeve and move, drive another gauge head and withstand the offside trough rim, tighten again lock-screw, mobile survey pin also is fixed, remove so again to read the scale numerical value on the blade, more can guarantee accuracy.
Therefore, the beneficial effects of the utility model are: (1) has measuring head structure, separately touches the diametric side of internal channel after can stretching into internal channel again, finishes smoothly the measurement of internal channel diameter; (2) have lock-screw, can make the survey pin be in stationary state, be convenient to the accuracy of reading and assurance reading.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: blade 1, survey pin 2, gauge head 3, vernier sliding sleeve 4, lock-screw 5.
Embodiment
Below by embodiment, by reference to the accompanying drawings the technical solution of the utility model is described further:
A kind of internal channel is as shown in Figure 1 measured slide calliper rule, comprises that blade 1, two survey pin 2, and it is towards the opposite that described survey pin 2 bottoms are provided with 3, two gauge heads 3 of surveying pin 2 bottoms of gauge head of level, and described gauge head 3 is parallel with blade 1 length direction.Described gauge head 3 is plate shape, and described gauge head 3 is circular arc away from the end with self phase tie-in pin 2.Gauge head 3 is used for and the internal channel sidewall contact, more fragile, manufactured Board shape can be improved and connected and self intensity, and gauge head 3 is with the sidewall contact of internal channel away from the end with self phase tie-in pin 2, circular arc can guarantee to be a contact, avoids causing measuring error larger because of gauge head 3 end out-of-flatnesses.One of described two survey pin 2 connect firmly with blade 1 one ends, another is surveyed pin 2 and is slidingly connected by vernier sliding sleeve 4 and blade 1, described vernier sliding sleeve 4 upper ends are provided with the lock-screw 5 that is threaded with vernier sliding sleeve 4, and described lock-screw 5 is in the middle part of vernier sliding sleeve 4.
When measuring the internal channel diameter dimension, the gauge head 3 of survey pin 2 bottoms that will connect firmly with blade 1 withstands first a trough rim on the internal channel length direction, then operating vernier sliding sleeve 4 moves, drive another gauge head 3 and withstand the offside trough rim, tighten again lock-screw 5, mobile survey pin 2 also is fixed, then reads the scale reading on the blade 1, namely finished measurement.
