Abstract
The utility belongs to the field of pneumatic measuring devices, and especially relates to a contact-type pneumatic measuring head for the external diameter of an annular shaft. The measuring head comprises an annular measuring head body, and the interior of the measuring head body is provided with an L-shaped air flow channel. One end of the air flow channel is arranged along the axial direction of the measuring head, and is connected with a spring baffle plate disposed on an inner wall of the measuring head body. The other end of the air flow channel is arranged along the axial direction of the measuring head body, and is connected with a spraying nozzle. The measuring head provided by the utility model is simple in structure, is reasonable in design, and can be used for the measurement of the external diameter of the annular shaft conveniently.
Description
Technical field
The utility model belongs to air measuring device field, relates in particular to a kind of Pneumatic measuring head of contact type measurement annular shaft external diameter.
Background technology
In prior art, be pneumatic ring type non-contact measurement outside dimension for the pneumatic gauging technological means of annular shaft external diameter.By comparing and measuring and show that external diameter is similar to actual value with standard component certified value.Due to non-contact measurement, measured workpiece surface can not be scratched, but during due to pneumatic ring type non-contact measurement, the nozzle location of its layout is limited, so can not measure the diameter at axle journal root 2 ~ 4mm place or cannot measure the too short annular shaft of axle journal.
Summary of the invention
The purpose of this utility model is to provide a kind of contact annular shaft external diameter Pneumatic measuring head, can be easily for annular shaft outside diameter measuring.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
Contact annular shaft external diameter Pneumatic measuring head, described measuring head comprises annular side head main body, in side head main body, be provided with L shaped gas channel, gas channel one end radially arranges along side head main body, and be connected with the spring stop being arranged on side head main body inwall, the other end axially arranges along side head main body, is connected with nozzle.
When work, the utility model is connected with pneumatic measuring instrument and source of the gas, examines and determine to putting into respectively upper and lower limit standard component in side head main body of the present utility model, and adjust air-gauge multiplying power and make measured value consistent with the calibration value of bound standard component.After calibrating, annular shaft is positioned in annular side head main body, nozzle is to jet in L shaped gas channel, air-flow flows out from the gas channel one end radially arranging along side head main body, contact with annular shaft outer wall, due to stopping of the spring stop on side head main body inwall, air-flow is to the diffluence of annular diameter of axle root, external diameter data to annular diameter of axle root place are measured, be presented on air-gauge, can read measured value from air-gauge, after measurement, close source of the gas, measuring head is separated to preservation with air-gauge.Above-mentioned upper and lower limit standard component serves as the rule effect of demarcating.
Preferably, described annular side head main body bottom is connected with handle by contiguous block.
Preferably, described handle is cylindrical.
The design of handle can facilitate staff to operation of the present utility model, and staff can operate the utility model by hand-held handle.
Preferably, described spring stop comprises that spring card and bulb survey son, and spring card axially arranges on side head main body inwall, its dorsad the one side of side head main body inwall be provided with bulb and survey son.
When work, spring card promotes bulb survey and contacts with the outer wall point of annular shaft, after flow out gas channel one end that air-flow radially arranges along side head main body, contact with annular shaft outer wall, survey stopping of son owing to being subject to bulb, air-flow, to the diffluence of annular diameter of axle root, is measured the external diameter data at annular diameter of axle root place, is presented on air-gauge.
Bulb is surveyed son apart from annular diameter of axle root >=2mm.
The utility model compared with prior art, tool has the following advantages: this Novel connecting touch annular shaft external diameter Pneumatic measuring head is simple in structure, reasonable in design, survey sub elastic reed with bulb and do baffle plate by adding below air stream outlet, because bulb survey contacts with measured workpiece point, and can be apart from measured workpiece diameter of axle root >=2mm, therefore the air-flow of nozzle ejection is subject to bulb and surveys stopping of son, flow to axle journal root 2mm place, diameter data is herein measured, then by comparing and measuring and show that external diameter is similar to actual value with bound standard component certified value.

Fig. 2 is the side-looking structural representation under the utility model duty;
Fig. 3 is Fig. 2 medi-spring baffle arrangement enlarged diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-3, contact annular shaft external diameter Pneumatic measuring head, comprise annular side head main body 1, in side head main body 1, be provided with L shaped gas channel 3, gas channel 3 one end radially arrange along side head main body 1, and are connected with the spring stop being arranged on side head main body 1 inwall, and the other end axially arranges along side head main body 1, be connected with nozzle 2, annular side head main body 1 bottom is connected with handle 9 by contiguous block 4.Described spring stop comprises that spring card 5 and bulb survey son 6, and spring card 5 axially arranges on side head main body 1 inwall, its dorsad the one side of side head main body 1 inwall be provided with bulb and survey son 6.Described handle 9 is cylindrical.
When work, the hand-held handle 9 of staff, the utility model is connected with pneumatic measuring instrument and source of the gas, then examines and determine to the interior upper and lower limit standard component of putting into respectively of side head main body 1, adjust air-gauge multiplying power and make measured value consistent with the calibration value of bound standard component.After calibrating, annular shaft 8 is positioned in annular side head main body 1, spring card 5 promotes bulb survey 6 and contacts with the outer wall point of annular shaft 8, nozzle 2 is interior jet to L shaped gas channel 3, after flow out gas channel 3 one end that air-flow radially arranges along side head main body 1, contact with annular shaft 8 outer walls, survey stopping of son 6 owing to being subject to bulb, air-flow is to annular diameter of axle root 7 diffluences, external diameter data to annular diameter of axle root 7 places are measured, be presented on air-gauge, staff can read measured value from air-gauge, after measurement, close source of the gas, measuring head is separated to preservation with air-gauge.Above-mentioned upper and lower limit standard component serves as the rule effect of demarcating.
Surveying son 6 due to bulb is 2 ~ 4mm apart from the spacing of annular diameter of axle root 7, so the utility model can be measured the diameter at annular shaft axle journal root 2 ~ 4mm place.
