Description

Technical Field

[0002] A constant temperature bath is a tank that can provide a constant temperature. It is heated by a resistance wire, cooled by a compressor, and assisted by a PID controller to maintain a relatively stable temperature.

[0003] In the current existing technology, the temperature uniformity and volatility in the thermostatic bath are important indicators of the performance of the thermostatic bath. Therefore, during the production and use process, the staff needs to test the temperature performance of the thermostatic bath. During the test, the staff will use two standard platinum resistance thermometers for testing at the same time. A fixed thermometer is placed at 1 / 2 depth of the working area of ​​the water tank, and the other mobile thermometer is placed on the horizontal plane of the working area to rotate multiple detection points. At a certain detection point, when the temperature is stable, the temperature values ​​of the fixed thermometer and the mobile thermometer are read at the same time, and then multiple horizontal planes are rotated according to different depths. The detection points on the above-mentioned multiple horizontal planes are detected in turn, and the detected values ​​are counted. After that, calculations and analysis are performed based on the above-mentioned values ​​to judge the temperature performance of the thermostatic bath, thereby completing the temperature performance test of the thermostatic bath.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Specific examples are given below.

[0024] See also Figure 1-5As shown, a thermostatic bath temperature performance test device comprises a fixing seat 12; a detection seat 13 is rotatably connected to the middle of the fixing seat 12; a plurality of jacks 19 are provided on the detection seat 13; a gear ring 14 is fixedly connected to the detection seat 13; a first stepper motor 15 is fixedly connected to the fixing seat 12; a first gear 16 is fixedly connected to the output end of the first stepper motor 15; the first gear 16 and the gear ring 14 are meshed with each other; a lifting mechanism is provided in the middle of the detection seat 13; a movable thermometer 18 is provided on the side of the lifting mechanism; the detection seat 13 can be inserted into the thermostatic bath from the top thereof;

[0025] Before use, the staff installs and fixes the fixing seat 12 above the thermostatic bath, aligns the detection seat 13 with the opening above the thermostatic bath, and installs the mobile thermometer 18 on the side of the lifting mechanism. The insertion depth of the mobile thermometer 18 can be changed by relying on the lifting mechanism. The lifting mechanism is a cylinder lifting mechanism or a motor screw 24 lifting mechanism. When performing the test, the first stepper motor 15 drives the first gear 16 to rotate, and the first gear 16 and the gear ring 14 are engaged, so that the gear ring 14 and the middle part of the gear ring 14 rotate and the mobile thermometer 18 rotates. The thermostatic bath is provided with multiple detection points on the same horizontal plane. After the mobile thermometer 18 rotates to the detection point, the detection point corresponds to the position of the jack 19, and the lifter The mechanism drives the mobile thermometer 18 to move downward, so that the mobile thermometer 18 passes through the jack 19 and is then inserted into the specified depth inside the thermostatic bath to read the temperature value, and then the lifting mechanism drives the mobile thermometer 18 to move upward and be pulled out of the thermostatic bath, and then the first stepper motor 15 drives the detection seat 13 to rotate, so that the mobile thermometer 18 moves to the next detection point, and the above steps are repeated. When all points on the same horizontal plane are detected, the stroke of the lifting mechanism is controlled, and the insertion depth of the mobile thermometer 18 is adjusted to test the temperature of horizontal planes at different depths. Relying on the above settings, it is possible to replace manual work to complete the temperature uniformity detection of the thermostatic bath, thereby reducing the workload of the staff and saving time and effort;

[0026] The detection seat 13 can be inserted into the interior of the constant temperature bath from the top, so as to lower the height of the detection seat 13 and thus lower the height of the entire device on the constant temperature bath. If the detection seat 13 is placed flat on top of the constant temperature bath, the depth of the constant temperature bath is deep, and it is difficult for the mobile thermometer to be inserted into the lowest detection point, so a longer mobile thermometer needs to be customized separately, and the adaptability range is small.

[0027] Further, such as Figure 3As shown, the lifting mechanism includes a second stepper motor 22 and a screw rod 24; the top of the detection seat 13 is fixedly connected to a fixing frame 21; the second stepper motor 22 is fixedly connected to the top of the fixing frame 21; the screw rod 24 is fixedly connected to the output end of the second stepper motor 22; the screw rod 24 is connected to a moving seat 23 through a ball screw nut pair; the mobile thermometer 18 is located on the side of the moving seat 23; in this embodiment, the screw rod 24 is driven to rotate by the second stepper motor 22, and with the cooperation of the ball screw 24 nut pair, the moving seat 23 is moved up and down in the vertical direction, and the mobile thermometer is installed on the moving seat 23, so as to change the insertion depth of the mobile thermometer 18.

[0028] Further, such as Figure 3 As shown, a third stepper motor 31 is fixedly connected to the side of the movable seat 23; a second gear is fixedly connected to the output end of the third stepper motor 31; a pair of jaws 34 are slidably connected to the movable seat 23 through a guide rail; a rack 33 is fixedly connected to the side of the jaw 34; the rack 33 and the second gear are meshed with each other; the mobile thermometer 18 is located between the pair of jaws 34; when in use, the third stepper motor 31 drives the second gear to rotate, thereby causing the rack 33 to move, and then causing the two corresponding jaws 34 to move, so that the jaws 34 complete the opening and closing actions, and the mobile thermometer 18 is located between the two jaws 34, so as to clamp and fix the thermometer, and the stability of the movement of the jaws 34 is ensured by the guide rail. Relying on the above arrangement, the mobile thermometer 18 can be easily replaced and installed.

[0029] Further, such as Figure 1-2 As shown in 4, a support 41 is fixedly connected to the middle of the detection seat 13; a fixed thermometer 43 is slidably connected to the middle of the support 41; a plurality of plastic bolts 42 are threadedly connected to the side of the support 41; during installation, the fixed thermometer 43 is inserted from the middle of the support 41, and then the fixed thermometer 43 is tightened by the plastic bolts 42, and the plastic bolts 42 are used to reduce the damage to the fixed thermometer 43 caused by excessive bolt torque, and the fixed thermometer 43 is used for comparative analysis with the numerical values ​​obtained by the mobile thermometer 18, so as to realize the temperature performance test of the constant temperature bath.

[0030] Further, such as Figure 2 As shown, a ball bearing 6 is installed at the connection between the fixing seat 12 and the detection seat 13; when in use, the ball bearing 6 can improve the rotation accuracy of the detection seat 13, improve the rotation stability, and reduce the friction during the rotation process.

[0031] Further, such as Figure 3As shown, guide rods 81 are fixedly connected on both sides of the fixed frame 21; linear bearings 82 are slidably connected to the guide rods 81; the linear bearings 82 are fixedly connected to the movable seat 23; when in use, the guide rods 81 and the linear bearings 82 cooperate to ensure the stability of the up and down movement of the movable thermometer 18.

[0032] Working principle: before use, the staff installs and fixes the fixing seat 12 on the top of the thermostatic bath, aligns the detection seat 13 with the opening on the top of the thermostatic bath, and the mobile thermometer 18 is installed on the side of the lifting mechanism. The insertion depth of the mobile thermometer 18 can be changed by relying on the lifting mechanism. The lifting mechanism is a cylinder lifting mechanism or a motor screw 24 lifting mechanism. When performing the test, the first stepper motor 15 drives the first gear 16 to rotate, and the first gear 16 and the gear ring 14 are meshed, so that the gear ring 14 and the middle part of the gear ring 14 rotate and the mobile thermometer 18 rotates. The thermostatic bath is provided with multiple detection points on the same horizontal plane. After the mobile thermometer 18 rotates to the detection point, the detection point corresponds to the position of the jack 19. The lifting mechanism drives the mobile thermometer 18 to move downward, so that the mobile thermometer 18 passes through the jack 19 and is then inserted into the specified depth inside the thermostatic bath to read the temperature value. Then, the lifting mechanism drives the mobile thermometer 18 to move upward and is pulled out of the thermostatic bath. Then, the first stepper motor 15 drives the detection seat 13 to rotate, so that the mobile thermometer 18 moves to the next detection point. The above steps are repeated. When all points on the same horizontal plane are detected, the stroke of the lifting mechanism is controlled to adjust the insertion depth of the mobile thermometer 18 to test the temperature of horizontal planes at different depths. Relying on the above settings, the temperature uniformity detection of the thermostatic bath can be replaced by manual work, which can reduce the workload of the staff and save time and effort.The detection seat 13 can be inserted into the interior of the thermostatic bath from the top, so as to lower the height of the detection seat 13, and then lower the height of the entire device on the thermostatic bath. If the detection seat 13 is placed flat on the top of the thermostatic bath, the depth of the thermostatic bath is deep, and it is difficult for the mobile thermometer to be inserted into the lowest detection point, so it is necessary to customize a longer detection temperature separately, and the adaptability range is small. In this embodiment, the second stepper motor 22 drives the screw rod 24 to rotate, and with the cooperation of the ball screw rod 24 nut pair, the mobile seat 23 is moved up and down in the vertical direction. The mobile thermometer is installed on the mobile seat 23, so as to change the insertion depth of the mobile thermometer 18. When in use, the third stepper motor 31 drives the second gear to rotate, so that the rack 33 is moved, and then the two corresponding clamps 34 are moved, so that the clamps 34 are opened and closed. The opening and closing actions, the mobile thermometer 18 is located between the two clamps 34, so as to clamp and fix the thermometer, and the guide rail is used to ensure the stability of the movement of the clamp 34. The mobile thermometer 18 can be easily replaced and installed by relying on the above settings. The fixed thermometer 43 is inserted from the middle of the support 41, and then the fixed thermometer 43 is tightened by the plastic bolt 42. The plastic bolt 42 is used to reduce the damage to the fixed thermometer 43 caused by excessive bolt torque. The fixed thermometer 43 is used to refer to and compare the values ​​obtained by the mobile thermometer 18 to improve the accuracy of detection. The ball bearing 6 can be set to improve the rotation accuracy of the detection seat 13, improve the stability of rotation, and reduce the friction during rotation. The guide rod 81 and the linear bearing 82 cooperate to ensure the stability of the up and down movement of the mobile thermometer 18. ;
