Description

Measuring components and their automatic replacement system

technical field

The present disclosure generally relates to the field of intelligent measuring equipment, and in particular to a measuring component and an automatic replacement system thereof.

Background technique

In industrial production, in order to produce products that meet the design requirements, multiple parameters such as the size, shape and position of each component or product (object to be measured) in production need to be measured by measuring equipment. With the advancement of science and technology, measuring equipment is becoming more and more intelligent, not only can accurately obtain multiple parameters such as the size, shape and position of the object to be measured, but also can adjust the measuring equipment itself to measure according to product needs, for example, three coordinates The measuring machine can measure the size and shape of the object to be measured by adjusting the probe, and at the same time, it can replace its own measuring parts (such as the measuring probe) according to different objects to be measured.

In the measuring equipment of the contact type (that is, the measurement method triggered by the electronic switch), such as a coordinate measuring machine, by moving the measuring probe from the origin to the surface of the object to be measured, a trigger signal is sent when the measuring probe touches the surface of the object to be measured, At this time, the measuring equipment can obtain the coordinates of the current measuring probe relative to the origin, and obtain multiple coordinate values by repeating the above-mentioned operations on the surface of the object to be measured multiple times, and then calculate the specific size of the object to be measured or obtain the shape by modeling. Therefore, most of the contact measuring probes use a normally closed electronic switch as the trigger component. At present, relatively intelligent measuring equipment is usually equipped with an automatic replacement device or system for measuring probes when the measuring probes are replaced in order to improve the installation accuracy of the measuring probes to ensure the original measuring accuracy. However, since the working mechanism of the measuring probe is similar to a normally closed electronic switch, when the measuring probe is replaced, if the measuring probe is disconnected from the part where the measuring probe is installed, the measuring system will mistakenly think that the measuring probe is probing, which may cause cause measurement errors or system crashes. In the prior art, software control is usually adopted, that is, an optimization algorithm is added to the measurement system and the automatic replacement system to solve this problem. For example, the patent CN109313019A discloses a CMM for identifying and confirming the stylus (ie three coordinates Measuring machine) equipment that implements certain instructions or guidelines when changing measuring probes (such as de-energizing the measuring probe or is considered to be in a de-energized state) so that the confirmation of the installation of the appropriate measuring probe is built into the automated part of the CMM measurement process, thus ensuring the implementation of Confirm the steps, and the result is correct.

However, compared with the hardware control method, the software control method has a lower fault tolerance rate. For example, in a three-dimensional coordinate measuring machine, the measurement system and the automatic replacement system will frequently interfere, which may lead to an increase in system errors, which in turn leads to the failure of the replacement of the measurement probe. , and affect subsequent measurement equipment to measure.

FIG. 7 is a schematic diagram showing a second opening state of the electronic switch 20 involved in the example of FIG. 5 of the present disclosure. FIG. 8 is a schematic diagram showing a third opening state of the electronic switch 20 involved in the example of FIG. 5 of the present disclosure. Wherein, the same components in FIG. 4 are only identified by a set of marks, that is, it can be understood that the number of the same components may be multiple, such as 2, 3, 4 or more.

In some examples, as shown in FIG. 3 , the detection assembly 112 may include a probe 1123 , a first trigger 1121 and a second trigger 1122 . In some examples, the probe 1123 can be used to contact the probe 1123 on the surface of the object to be measured, the first trigger 1121 can be connected to the probe 1123, and the second trigger 1122 can cooperate with the first trigger 1121 to form an electronic switch 20 .

In the present disclosure, the detection component 112 can be configured to output a channel signal when the first trigger 1121 is in contact with the second trigger 1122, and when the probe 1123 contacts the surface of the object to be measured, the first trigger 1121 and the second trigger 1122 does not touch and outputs a trigger signal. In this case, the detection assembly 112 forms the electronic switch 20 through the cooperation of the first trigger piece 1121 and the second trigger piece 1122, and the first trigger piece 1121 is connected to the probe 1123, when the probe 1123 does not touch the surface of the object to be measured The first trigger 1121 and the second trigger 1122 are in contact with each other, that is, the electronic switch 20 is in the closed state, and the detection component 112 can output a channel signal.

A trigger piece 1121 opens the electronic switch 20, that is, the first trigger part 1122a breaks contact with the first trigger piece 1121 or the second trigger piece 1122 breaks contact with the first trigger piece 1121, thereby enabling the detection assembly 112 to output The trigger signal is convenient for the measurement component 11 to complete the measurement; in addition, the first trigger part 1122a and the second trigger part 1122b cooperate with the first trigger part 1121 to form the electronic switch 20, which can also reduce the inconvenience of setting wires on the first trigger part 1121.

In some examples, when the first trigger part 1122a is in contact with the first trigger part 1121 and the second trigger part 1122b is in contact with the first trigger part 1121, the detection component 112 can output a pass signal, that is, referring to the situation shown in FIG.
