Description
Technical field
The utility model relates to the structure of a kind of temperature measuring equipment, particularly automatic TME.
Background technology
Calibration cell is with certain material (Ru Shui, oil, alcohol etc.) for medium, and temperature control also can reach the device of certain stability and homogeneity degree.At present, test for these two indexs of calibration cell verifies, substantially be all the loaded down with trivial details combination by digital multimeter (bridge for measuring temperature), standard platinum resistance thermometer and switch, and realized by manual switching test point, manual record and conversion of manually tabling look-up, effort during test fee.Therefore, each puts thermometric self-operated measuring unit for calibration cell to be badly in need of one.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of automatic TME, simplifies stability and the uniformity index checking procedure of calibration cell, realizes automation data and measures, save time.
The technical solution of the utility model is: a kind of automatic TME, comprise the upper dish and lower wall that are connected by pole, the disk body of upper dish and lower wall all has ring groove, axial centerline between upper dish and lower wall is provided with motor case body, hollow rack is had outside motor case body, and hollow rack is placed in ring groove, mobile standard temperature sensor is had in hollow rack, the upper axle of motor case body passes upper dish and is connected with the axle of the planetary reduction gear stepper motor on upper disk surface, also hollow tubular is provided with outside central axis between upper dish and lower wall, fixed temperature sensor is had in hollow tubular.
Coil on described, and the extreme position of the vertical movement and horizontal revolving motion that correspond respectively to mobile standard temperature sensor is equipped with four position detecting switchs.
The lower shaft of described motor case body is arranged in the axle bed of lower wall by ball bearing.
Described motor case body two ends are provided with baffle plate.
The utility model forms fixing test pedestal by upper dish, lower wall, pole.Motor case body is installed on the axial centerline between upper and lower dish, and mobile standard temperature sensor is arranged in the hollow rack outside motor case body.Tooth bar, by the driving stepper motor in motor housing, realizes movement and the location of the vertical direction of mobile standard temperature sensor in calibration cell and upper-lower position.The lower shaft of motor case body is arranged in the axle bed of lower wall, and the upper axle of motor case body is connected with the output shaft of the planetary reduction gear stepper motor be arranged on upper disk surface through upper dish.Planetary reduction gear driving stepper motor motor case body rotates along the central axis of upper and lower dish, mobile standard temperature sensor can rotate along in the ring groove of upper and lower dish, realizes movement and the location of mobile standard temperature sensor horizontal level in calibration cell.Fixed temperature sensor is arranged in the hollow tubular outside upper and lower disk center, and sensor upper-lower position is removable, can insert the different depth in calibration cell during test as requested.
Upper coiling is equipped with four position detecting switchs, corresponding with the vertical movement of mobile standard temperature sensor and the extreme position of horizontal revolving motion respectively.The effect one of detector switch is the judgement for initial point position, and concrete position location is determined by the rotation step number of stepper motor.The position limitation protection under fortuitous event is played in another effect.
Compared with the prior art, the utility model enormously simplify the labour intensity of temperature taking process, owing to being driven by motor with the movement of horizontal circle circumferential direction in the vertical direction, the stability of measurement and homogeneity is ensured fully.

Embodiment
As shown in Fig. 1 ~ 15, calibration cell automatic TME comprises the fixing test pedestal be made up of upper dish 1, lower wall 8, pole 3, wherein goes up dish 1, lower wall 8 and adopts nut to be fixedly connected with the upper and lower end of pole 3 respectively.Upper dish 1 and lower wall 8 have the ring groove 11 with disk body coaxial cable, as the track that hollow rack 7 is in rotary moving.Motor case body 2 is installed on the axial centerline between upper and lower dish, mobile standard temperature sensor (employing standard platinum resistance) is arranged in the hollow rack 7 outside motor case body 2, limited location hole, tooth bar 7 upper end, spacing hole is connected with gag lever post 14, plays position-limiting action.Tooth bar 7, by the driving stepper motor in motor case body 2, by gear 13 and flat key 12, realizes movement and the location of the vertical direction upper-lower position of standard temperature sensor in calibration cell.The lower shaft of motor case body 2 is arranged in the axle bed 10 of lower wall 8, and upper axle is connected with the output shaft of the planetary reduction gear stepper motor 5 be arranged on 1, upper dish through upper dish 1.Planetary reduction gear stepper motor 5 drive motor casing 2 rotates along the central axis of upper and lower dish, mobile standard temperature sensor can rotate along in the ring groove 11 of upper and lower dish, realizes movement and the location of mobile standard temperature sensor horizontal level in calibration cell.Fixed temperature sensor is arranged in the hollow tubular 4 outside upper and lower disk center, and sensor upper-lower position is removable, can insert the different depth in calibration cell during test as requested.
Upper dish 1 is equipped with four position detecting switchs, corresponding with the vertical movement of mobile standard temperature sensor and the extreme position of horizontal revolving motion respectively.The effect one of detector switch is the judgement for initial point position, and concrete position location is determined by the rotation step number of stepper motor.The position limitation protection under fortuitous event is played in another effect.
