Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

Example 1

As shown in FIG. 1, an automatic temperature measurement temperature control system device of diamond compact mirror finish, including polishing anchor clamps 1, drain pipe 2, drinking-water pipe 3, suction pump 4, drain pump 5 and automatically controlled host computer 6, the inside of polishing anchor clamps 1 is equipped with the open cooling water chamber 7 in top, cooling water chamber 7 is for centering on the annular water chamber of 8 hearts of polishing anchor clamps rotation axis, the exit end of drinking-water pipe 3 and the entrance point of drain pipe 2 get into inside cooling water chamber 7 from the uncovered department in top, the drinking-water pipe 3 with drain pipe 2 is external respectively suction pump 4 and drain pump 5, automatically controlled host computer 6 control connection suction pump 4 and drain pump 5 to control opening of suction pump 4 and drain pump 5 and stop the state.

In order to meet the installation requirement, the water pump further comprises an external guide rail, and the drain pipe, the water pumping pipe and the electric control host 6 are all fixed on the external guide rail.

The working principle is as follows: the application of the device needs to be based on empirical data of long-term experiments, how long water needs to be replaced for a single time, the replacement flow and time and the like, the data are set in advance, then the electric control host 6 controls the water suction pump 4 and the water discharge pump 5 to work according to a set program, for example, water needs to be replaced every 1 minute, 10 seconds are needed for completing the water replacement work, then the water suction pump 4 and the water discharge pump 5 work every 1 minute for 10 seconds, the mode is suitable for products with relatively extensive temperature control, through control, basic control of polishing temperature can be realized, and the problems of thermal damage and underground polishing efficiency caused by overhigh temperature in the polishing process are avoided.

Example 2

As shown in fig. 2, if fine temperature control is needed, a temperature sensor 9 needs to be added, the temperature sensor 9 is suspended in the cooling water cavity 7 by a hollow nylon insulating tube 10 and used for collecting the temperature of cooling water, the temperature sensor 9 is externally connected to an electric control host 6 from an open top end, a wire is fixed on an external guide rail, and the electric control host 6 controls the start and stop states of the water suction pump 4 and the water discharge pump 5 according to collected temperature data.

The working principle is as follows: the range of well setting the control by temperature change in advance among the automatically controlled host computer 6 sets for highest temperature and target temperature, and when the temperature reachd the highest temperature, control suction pump 4 and drain pump 5 started, and the cooling water in the replacement cooling water chamber 7, it is to reachd the target temperature, control suction pump 4 and drain pump 5 shut down, keep the temperature, and this kind of mode can be with temperature control in the interval of relative invariant, and control mode is more convenient, high-efficient, accurate.

Example 3

As shown in fig. 3 and 4, since the operations of the suction pump 4 and the drain pump 5 are not easily controlled in synchronization, and the loss of the cooling water occurs at all times, the presence of these interference factors can lead to an unstable water volume in the cooling water chamber 7, to irregular temperature variations, which are not easy to control, and in the long run can even lead to emptying or spillage, therefore, a liquid level sensor 11 is required, the liquid level sensor 11 is a 3-point liquid level sensor, a plurality of induction electrodes of the liquid level sensor 11 are arranged in the hollow nylon insulating pipe 10 according to a set interval, the hollow nylon insulating pipe 10 is suspended in the cooling water cavity 7, used for collecting the liquid level height of cooling water, the liquid level sensor is externally connected to the electric control host 6 from the top end opening, a lead is fixed on the external guide rail, and the electric control host controls the starting and stopping states of the water suction pump and the drainage pump according to the obtained liquid level height data.

The working principle is as follows: the positions of three induction electrodes of the liquid level sensor 11 are the highest point, the lowest point and a target point of the liquid level, when the liquid level exceeds the highest point, a drainage pump is started to discharge redundant water until the drainage pump reaches the target point, and the machine is stopped; when the liquid level exceeds the lowest point, the water suction pump is started to pump new water, and the machine is stopped until a target point is reached, so that the constant of the water quantity in the cooling water cavity 7 is realized, and the stable operation of the temperature control system is ensured.

Generally, the liquid level control and the temperature control are not controlled simultaneously, and the liquid level control and the temperature control are not interfered with each other, for example, the liquid level is reduced due to the drainage in the temperature control process, or the temperature is increased when the water level is reduced, the water pump is turned on in the two controls, the targets are consistent, and vice versa, so that the problem does not need to be considered.

When the working state of the pump is abnormal or the data of the temperature sensor 9 and the liquid level sensor 11 are out of the detection range for a long time, an alarm is sent out.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
