Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
As shown in fig. 1 to 3, a titration experiment device, including experiment platform 1, 1 top of experiment platform is equipped with titration frame 2, installs buret 3 on the titration frame 2, buret 3 below is equipped with erlenmeyer flask 4, erlenmeyer flask 4 is located in roating seat 5, 6 tops of rotary platform are located to roating seat 5 bottom, 6 bottoms of rotary platform are connected with servo motor 7's output shaft is articulated, and 6 downside articulations of rotary platform are equipped with a plurality of gyro wheels 8, gyro wheel 8 cooperates with circular orbit 12 of 1 top surface of experiment platform.
Preferably, roating seat 5 is cuboid cell body structure, rotary platform 6 is the cylinder structure, and 5 bottoms of roating seat are installed in the square groove at rotary platform 6 tops. After the design, when servo motor 7 during operation, can drive rotary platform 6 and rotate, and then make roating seat 5 rotate to drive erlenmeyer flask 4 and rotate, shake even process.
Preferably, a plurality of first springs 9 are arranged on the inner side wall of the rotating base 5, the first springs 9 are connected with a conical pressing block 10, and the conical pressing block 10 is matched with the conical surface of the conical bottle 4. Through the elastic force effect of first spring 9, after putting into roating seat 5 conical flask 4, conical surface briquetting 10 can compress tightly conical flask 4, prevents that it from shaking even in-process and taking place the not hard up phenomenon of bottle.
Preferably, the top of the output shaft of the servo motor 7 is of a spherical structure, a spherical groove is formed in the center of the bottom of the rotating platform 6, and the center of the bottom of the rotating platform 6 is in spherical hinge connection with the top of the output shaft of the servo motor 7.
Preferably, a plurality of second springs 11 are arranged on the top of the output shaft of the servo motor 7 and the bottom of the rotary platform 6.
Preferably, the bottom surface of the annular rail 12 is provided with a plurality of concave surfaces 12.1.
In above-mentioned technical scheme, because rotary platform 6 bottom center and servo motor 7 output shaft top ball joint, so when gyro wheel 8 of rotary platform 6 bottom rolls a plurality of concave surfaces 12.1 of the bottom surface of annular track 12, rotary platform 6 can take place the slope, slope every time can make erlenmeyer flask 4 produce the slope, consequently erlenmeyer flask 4 itself is when taking place the rotation, and also can be along with rotary platform 6's slope and slope, the even process of hand is used in the simulation, the even effect of shaking of this kind of even mode is better. In addition, because the center of the bottom of the rotary platform 6 is in spherical hinge with the top of the output shaft of the servo motor 7, in order to prevent the output shaft of the servo motor 7 from generating a relative rotation 'slip' phenomenon with the bottom of the rotary platform 6 when rotating, a plurality of second springs 11 are arranged to reduce the slip phenomenon, and simultaneously, the inclination process of the rotary platform 6 is not influenced, and the second springs 11 can play a role in buffering in the inclination process.
The working principle of the embodiment is as follows:
before a titration experiment, firstly, the conical flask 4 is placed in the rotating seat 5, and the conical pressing block 10 can tightly press the conical flask 4 to prevent the flask from loosening in the shaking process; in the process of a titration experiment, when the servo motor 7 works, the rotary platform 6 is driven to rotate, so that the rotary seat 5 rotates, the conical flask 4 is driven to rotate, and a shaking process is carried out; when the gyro wheel 8 of rotary platform 6 bottom rolls a plurality of concave surfaces 12.1 of the bottom surface of annular track 12, rotary platform 6 can take place the slope, and the slope can make erlenmeyer flask 4 produce the slope each time, therefore erlenmeyer flask 4 itself when taking place the rotation, also can incline along with rotary platform 6's slope moreover, and the even process of hand is used in the simulation, and the even effect of shaking of this kind of even mode of shaking is better.
