The measuring component includes a mounting assembly and a detection assembly detachably mounted on the mounting assembly. The detection assembly includes a probe for contacting the surface of an object to be measured, a first trigger member connected to the probe, and a second trigger member that cooperates with the first trigger member to form an electronic switch. The detection assembly is configured to output a conduction signal when the first trigger member contacts the second trigger member, and when the probe contacts the surface of the object to be measured, the first trigger member and the second trigger member do not contact and a trigger signal is output.

Description

Technical Field

[0001] The present disclosure generally relates to the field of intelligent measuring equipment, and more particularly to a measuring component and an automatic replacement system thereof. Background Art

[0002] In industrial production, to produce products that meet design requirements, measuring equipment is required to measure multiple parameters, such as the size, shape, and position of each component or product (the object to be measured). With technological advancements, measuring equipment is becoming increasingly intelligent, not only able to accurately determine multiple parameters such as the size, shape, and position of the object to be measured, but also able to adjust the measuring equipment itself to meet product requirements. For example, a three-dimensional coordinate measuring machine can measure the size and shape of the object to be measured by adjusting the probe, and its measuring components (such as the measuring probe) can be replaced according to the different objects to be measured.

[0003] In contact-type measuring equipment (i.e., measurement methods triggered by electronic switches), such as three-dimensional coordinate measuring machines, a measuring probe is moved from an origin to the surface of the object to be measured. When the measuring probe contacts the surface of the object to be measured, a trigger signal is sent. At this time, the measuring device can obtain the coordinates of the current measuring probe relative to the origin. By repeating the above operation multiple times on the surface of the object to be measured, multiple coordinate values are obtained, from which the specific dimensions of the object to be measured or the shape of the object to be measured are calculated. Therefore, contact-type measuring probes mostly use a normally closed electronic switch as a trigger component. Currently, more intelligent measuring equipment is usually equipped with an automatic measuring probe replacement device or system when the measuring probe is replaced in order to improve the installation accuracy of the measuring probe and ensure the original measurement accuracy. However, because the working mechanism of the measuring probe is similar to that of a normally closed electronic switch, when the measuring probe is replaced, if the measuring probe is disconnected from the location where the measuring probe is installed, the measuring system will mistakenly believe that the measuring probe is performing a detection, which may cause measurement errors or system crashes. In the prior art, software control is usually adopted, that is, adding optimization algorithms to the measurement system and the automatic replacement system to solve this problem. For example, the patent application with patent publication number CN109313019A discloses a CMM (coordinate measuring machine) device for identifying and confirming the stylus. When replacing the measuring probe, certain instructions or criteria are executed (such as powering off the measuring probe or assuming that it is in a power-off state) so that the confirmation of the installation of the appropriate measuring probe is built into the automated part of the CMM measurement process, thereby ensuring that the confirmation step is executed and the result is correct.

[0004] However, compared with hardware control, software control has a lower fault tolerance. For example, in a three-coordinate measuring machine, the measurement system and the automatic replacement system will often interfere with each other, which may lead to increased system errors, and then cause the measurement probe to fail to be replaced, and affect the subsequent measurement equipment to perform measurements. Summary of the Invention

[0005] The present disclosure is completed in view of the above-mentioned state of the prior art, and its object is to provide a measuring component and its automatic replacement system, which can solve the problem of replacement failure of the measuring component due to the structural limitation of its own triggering component through a hardware control method, thereby improving the intelligence level of the measuring device.

[0006] To this end, the first aspect of the present disclosure first describes a measuring component, which is a measuring component based on an electronic switch-triggered measurement method, including a mounting component and a detection component detachably mounted on the mounting component and configured to contact the surface of the object to be measured and output a trigger signal at the same time. The detection component includes a probe for contacting the surface of the object to be measured, a first trigger connected to the probe, and a second trigger that cooperates with the first trigger to form the electronic switch. The detection component is configured to output a path signal when the first trigger contacts the second trigger, and the first trigger and the second trigger are not in contact and output the trigger signal when the probe contacts the surface of the object to be measured; the mounting component includes a magnetic control component in parallel with the electronic switch and having a switching function, and the mounting component is configured to conduct and output the path signal when the magnetic control component responds to a magnetic field change.

[0007] In the first aspect of the present disclosure, the detection component is detachably mounted on the mounting component, which can facilitate the replacement of the detection component of the measuring component according to different objects to be measured; the detection component forms an electronic switch through the cooperation of the first trigger and the second trigger, and the first trigger is connected to the probe. When the probe does not contact the surface of the object to be measured, the first trigger and the second trigger are in contact with each other, that is, the electronic switch is in a closed state, and the detection component can output a path signal. When the probe contacts the surface of the object to be measured, the first trigger and the second trigger are disconnected, that is, the electronic switch is opened by the probe connected to the first trigger, and the detection component can output a trigger signal. Thus, it can facilitate the measuring device to detect through the detection component by using a contact measurement method to obtain information such as the size, shape or position of the object to be measured; the magnetic control component in the mounting component has a switching function and is in parallel with the electronic switch circuit in the detection component. When responding to a magnetic field change, the mounting component can replace the electronic switch and output a path signal, and further can make the measurement system think that the detection component is not in a triggered measurement state when the detection component is replaced. Thus, it can reduce the error rate of the measurement system, that is, it can solve the problem of inaccurate replacement of the measuring component due to the structural limitation of its own triggering component through a hardware control method, thereby improving the accuracy of the device.

[0008] In addition, according to the measuring component involved in the present disclosure, optionally, the second trigger includes a first trigger portion and a second trigger portion, and the detection assembly is further configured to output the path signal when the first trigger portion contacts the first trigger and the second trigger portion contacts the first trigger, and output the trigger signal when the first trigger portion disconnects from the first trigger or when the second trigger portion disconnects from the first trigger. In this case, an electronic switch can be formed by the cooperation of the first trigger portion and the second trigger portion with the first trigger. When the probe contacts the surface of the object to be measured, the first trigger connected to the probe can open the electronic switch, that is, the first trigger portion disconnects from the first trigger or the second trigger disconnects from the first trigger, thereby enabling the detection assembly to output a trigger signal to facilitate the measuring component to complete the measurement. In addition, by forming an electronic switch through the cooperation of the first trigger portion and the second trigger portion with the first trigger, the inconvenience of arranging wires on the first trigger can also be reduced.

[0009] In addition, according to the measuring component involved in the present disclosure, optionally, the magnetic control includes a first switch portion and a second switch portion, and the mounting assembly is further configured to output the path signal when the first switch portion contacts the second switch portion when approaching a preset magnetic field, and the first switch portion does not contact the second switch portion when away from the preset magnetic field. In this case, through the first switch portion and the second switch portion, the magnetic control can function as a switch, and by being connected in parallel with the electronic switch circuit formed by the first trigger and the second trigger, it can replace the electronic switch when replacing the detection assembly of the measuring component and output a path signal under the action of the magnetic field, that is, when the detection assembly is replaced, the magnetic field control circuit path can be used to make the measurement system consider that the detection assembly is not in the triggered measurement state, thereby reducing the error rate of the measurement system.

[0010] In addition, according to the measuring component involved in the present disclosure, optionally, a plurality of the first triggers and a plurality of the second triggers cooperate to form a plurality of the electronic switches, and the plurality of the electronic switches are connected in series or in parallel with each other. In this case, triggering through a plurality of electronic switches can improve the sensitivity of the detection assembly of the measuring component to contact the surface of the object to be measured during detection, thereby improving the measurement accuracy.

[0011] In addition, according to the measuring component involved in the present disclosure, optionally, the resistance value of the magnetic control component is equal to the equivalent resistance value after a plurality of the electronic switches are connected in series or in parallel. In this case, a plurality of electronic switches are connected in series or in parallel and then connected in parallel with the magnetic control component circuit, and the resistance value of the magnetic control component is equal to the equivalent resistance value after a plurality of electronic switches are connected in series or in parallel. When replacing the detection component of the measuring component, the path signal that the magnetic control component can output under the action of the magnetic field is the same as the path signal after a plurality of electronic switches are connected in series or in parallel, improving the consistency of the output path signal. Thus, a plurality of electronic switches can be replaced, and when the detection component is replaced, the magnetic field control circuit path is used to make the measuring system think that the detection component is not in the triggered measuring state, thereby reducing the error rate of the measuring system.

[0012] In addition, according to the measuring component involved in the present disclosure, optionally, the detection component and the mounting component are mounted and disassembled by at least one of threading, magnetic attraction or snap connection. In this case, it is possible to facilitate the detachable mounting of the detection component on the mounting component, and the mounting accuracy can be improved by adjusting the threading accuracy, magnetic attraction accuracy or snap connection accuracy. Thus, the measuring accuracy of the measuring component can be improved.

[0013] A second aspect of the present disclosure describes an automatic replacement system for a measuring component, including: a measuring component based on a measuring method triggered by an electronic switch, a driving device for driving the measuring component to move, and a placement device forming a preset magnetic field. The measuring component includes a mounting component and a detection component detachably mounted on the mounting component and configured to contact the surface of the object to be measured and output a trigger signal at the same time. The detection component includes a probe for contacting the surface of the object to be measured, a first trigger member connected to the probe, and a second trigger member cooperating with the first trigger member to form the electronic switch. The detection component is configured to output a path signal when the first trigger member contacts the second trigger member, and the first trigger member and the second trigger member are not in contact and output the trigger signal when the probe contacts the surface of the object to be measured; the mounting component includes a magnetic control component connected in parallel with the electronic switch and having a switching function, and the mounting component is configured to conduct the magnetic control component and output the path signal when the magnetic control component responds to the preset magnetic field; the driving device is configured to drive the measuring component to move to the placement device and be located in the preset magnetic field; the placement device is configured to place and replace the detection component.

[0014] In a second aspect of the present disclosure, by driving a measurement component to move into a placement device with a preset magnetic field through a driving device, the detection component detachably mounted on the mounting component in the measurement component can be replaced in the placement device; the detection component forms an electronic switch through the cooperation of a first trigger and a second trigger, and the first trigger is connected to a probe. When the probe does not contact the surface of the object to be measured, the first trigger and the second trigger are in contact with each other, that is, the electronic switch is in a closed state, and the detection component can output a path signal. When the probe contacts the surface of the object to be measured, the first trigger and the second trigger are separated from each other, that is, the electronic switch is opened through the probe connected to the first trigger, and the detection component can output a trigger signal. Thus, it is convenient for the measuring device to perform detection by means of contact measurement through the detection component to obtain information such as the size, shape, or position of the object to be measured; the magnetic control component in the mounting component has a switching function and is connected in parallel with the electronic switch circuit in the detection component. When responding to the preset magnetic field of the placement device, the mounting component can replace the electronic switch and output a path signal, thereby enabling the measurement system to consider that the detection component is not in a triggered measurement state when the detection component is replaced, that is, when it moves into the placement device. Thus, the error rate recognized by the measurement system can be reduced, that is, the problem of inaccurate replacement of the measurement component due to the structural limitations of its own trigger component can be solved by means of hardware control, and thus the accuracy of the device can be improved.

[0015] In addition, according to the automatic replacement system involved in the present disclosure, optionally, the magnetic control component includes a first switch portion and a second switch portion, and the mounting component is further configured such that when approaching the preset magnetic field, the first switch portion contacts the second switch portion and outputs the path signal, and when away from the preset magnetic field, the first switch portion does not contact the second switch portion. In this case, through the first switch portion and the second switch portion, the magnetic control component can have a switching function, and by being connected in parallel with the electronic switch circuit formed by the first trigger and the second trigger, it can replace the electronic switch and output a path signal under the action of the magnetic field when replacing the detection component of the measurement component, that is, it can make the measurement system consider that the detection component is not in a triggered measurement state by controlling the circuit path through the magnetic field when the detection component is replaced, and thus the error rate of the measurement system can be reduced.

[0016] In addition, according to the automatic replacement system involved in the present disclosure, optionally, a plurality of the first triggers and a plurality of the second triggers cooperate to form a plurality of the electronic switches, and the plurality of the electronic switches are connected in series or in parallel with each other. In this case, by triggering through a plurality of electronic switches, the sensitivity of the detection component of the measurement component to contact the surface of the object to be measured during detection can be improved, and thus the measurement accuracy can be improved.

[0017] In addition, according to the automatic replacement system involved in the present disclosure, optionally, the resistance value of the magnetic control component is equal to the equivalent resistance value after a plurality of the electronic switches are connected in series or in parallel. In this case, a plurality of electronic switches are connected in series or in parallel and then connected in parallel with the magnetic control component circuit, and the resistance value of the magnetic control component is equal to the equivalent resistance value after a plurality of electronic switches are connected in series or in parallel. When replacing the detection component of the measurement component, the path signal that the magnetic control component can output under the action of the magnetic field is the same as the path signal after a plurality of electronic switches are connected in series or in parallel, improving the consistency of the output path signal. Thus, a plurality of electronic switches can be replaced, and when the detection component is replaced, the magnetic field control circuit path is used to make the measurement system think that the detection component is not in the triggered measurement state, thereby reducing the error rate of the measurement system.

[0018] According to the present disclosure, a measurement component and its automatic replacement system can be provided, which can solve the problem of replacement failure of the measurement component due to the structural limitation of its own trigger component through a hardware control method, thereby improving the intelligence level of the measurement device.

[0035] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments filled by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present disclosure.

[0036] It should be noted that the terms "first", "second", "third", "fourth", etc. in the description, claims and above-mentioned drawings of the present disclosure are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products or devices. In the following description, the same reference signs are given to the same components, and repeated descriptions are omitted. Additionally, the drawings are only schematic diagrams, and the proportional relationship of the sizes between components or the shapes of components, etc. may be different from the actual ones.

[0037] The present disclosure describes a measuring component and its automatic replacement system. Among them, the measuring component involved in the present disclosure can be a mechanism for measurement in a measuring device, such as a probe module, a touch probe module, etc. In some examples, the measuring device can be a coordinate measuring machine, and the measuring component can be a probe module or a touch probe module of the coordinate measuring machine. In particular, in some examples, the measuring component can be a measuring component based on the measurement method triggered by an electronic switch. In some examples, the measurement method triggered by an electronic switch can refer to a measurement method in which when a specific component or mechanism contacts the surface of an object to be measured, a contact trigger signal is sent, and based on the trigger signal, the coordinates of the current specific component or mechanism relative to the origin are obtained, and then the dimensions, shape, etc. of the object to be measured are obtained through calculation.

[0038] As mentioned in the background art, since the working mechanism of the measuring probe (i.e., the measuring component) is similar to that of a normally closed electronic switch, when the measuring probe is replaced, the disconnection between the measuring probe and the part where the measuring probe is installed will also be erroneously recognized by the measuring system as the measuring probe is conducting detection, which may lead to measurement errors or system crashes. In the prior art, a software control method is usually adopted, that is, an optimization algorithm is added to the measuring system and the automatic replacement system to solve this problem. However, compared with the hardware control method, the software control method has a lower fault tolerance rate. In a coordinate measuring machine, for example, the measuring system and the automatic replacement system often interfere with each other, which may lead to an increase in system errors, and further lead to inaccurate replacement of the measuring probe and affect the measurement accuracy when the subsequent measuring device performs measurement.

[0039] Accordingly, the present disclosure provides the following two aspects. Specifically, the present disclosure provides a measuring component and its automatic replacement system, which can solve the problem of replacement failure of the measuring component due to the structural limitation of its own triggering component through hardware control, thereby improving the intelligence level of the measuring device. In some examples, the measuring component and its automatic replacement system involved in the present disclosure may also be referred to as "contact measuring component and its automatic replacement system", "contact probe and its replacement system", "probe based on electronic switch triggering measurement and its replacement system", or "contact probe of coordinate measuring machine and its automatic replacement system", etc.

[0040] The following will first describe the first aspect of the present disclosure in detail with reference to the accompanying drawings. Figure 1 is a schematic structural diagram showing the measuring component 11 involved in the example of the present disclosure. Figure 2 is a schematic diagram showing the detachable installation of the detection component 112 and the installation component 111 in the measuring component 11 involved in the example of the present disclosure.

[0041] The first aspect of the present disclosure describes a measuring component 11, as Figure 1 shown, the measuring component 11 may include an installation component 111 and a detection component 112. In some examples, the detection component 112 may be used to contact the surface of the object to be measured and output a trigger signal at the same time, and the installation component 111 may be used to install the detection component 112 and enable the detection component 112 to be electrically connected to the host of the measuring device. In this case, the measuring component 11 can be formed by the detection component 112 and the installation component 111 to perform contact measurement on the object to be measured.

[0042] In some examples, the trigger signal may refer to a detection signal without current or with voltage not within the preset value range when the detection component 112 is detected by the detection device. In addition, the path signal involved in the present disclosure may refer to a detection signal with current or voltage at a predetermined value when the detection component 112 or the installation component 111 is detected by the detection device.

[0043] In some examples, as Figure 2 shown, the detection component 112 may be detachably installed on the installation component 111. In this case, the detection component 112 is detachably installed on the installation component 111, which can facilitate the replacement of the detection component 112 of the measuring component 11 according to different objects to be measured.

[0044] Figure 3 is a schematic structural diagram showing the detection component 112 involved in the example of the present disclosure after being simplified. Figure 4 is a schematic diagram showing the present disclosure Figure 1 or Figure 2 a top view of the internal structure of the detection component 112 involved in the example.Figure 5 It is a schematic diagram showing the working principle of the electronic switch 20 involved in the examples of the present disclosure. Figure 6 It is shown the present disclosure Figure 5 A schematic diagram showing the first opening situation of the electronic switch 20 involved in the examples of the present disclosure. Figure 7 It is shown the present disclosure Figure 5 A schematic diagram showing the second opening situation of the electronic switch 20 involved in the examples of the present disclosure. Figure 8 It is shown the present disclosure Figure 5 A schematic diagram showing the third opening situation of the electronic switch 20 involved in the examples of the present disclosure. Among them, Figure 4 The same components are only identified by a set of labels, that is, it can be understood that the number of the same components can be multiple, such as 2, 3, 4 or more.

[0045] In some examples, as Figure 3 shown, the detection component 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 the electronic switch 20.

[0046] [[ID=Twenty-three]]In the present disclosure, the detection component 112 can be configured to output a path signal when the first trigger 1121 contacts 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 are not in contact and a trigger signal is output. In this case, the detection component 112 forms the electronic switch 20 through the cooperation of the first trigger 1121 and the second trigger 1122, and the first trigger 1121 is connected to the probe 1123. When the probe 1123 does not contact 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 a closed state, and the detection component 112 can output a path signal. When the probe 1123 contacts the surface of the object to be measured, the first trigger 1121 and the second trigger 1122 are disconnected from each other, that is, the electronic switch 20 is opened through the probe 1123 connected to the first trigger 1121, and the detection component 112 can output a trigger signal. Thus, it can facilitate the measuring device to perform detection by using a contact measurement method through the detection component 1…

[0047] In some examples, as Figure 4 shown, the second trigger 1122 may include a first trigger portion 1122a and a second trigger portion 1122b.

[0048] In some examples, the detection component 112 can also be configured to output a path signal when the first trigger part 1122a contacts the first trigger member 1121 and the second trigger part 1122b contacts the first trigger member 1121 (see Figure 5 ), and output a trigger signal when the first trigger part 1122a disconnects from the first trigger member 1121 or the second trigger part 1122b disconnects from the first trigger member 1121 (see Figure 6 , Figure 7 or Figure 8 ). In this case, the first trigger part 1122a and the second trigger part 1122b cooperate with the first trigger member 1121 to form an electronic switch 20, which can open the electronic switch 20 through the first trigger member 1121 connected to the probe 1123 when the probe 1123 contacts the surface of the object to be measured, that is, the first trigger part 1122a disconnects from the first trigger member 1121 or the second trigger member 1122 disconnects from the first trigger member 1121. Thus, the detection component 112 can output a trigger signal to facilitate the measurement component 11 to complete the measurement; in addition, by forming the electronic switch 20 with the first trigger part 1122a and the second trigger part 1122b cooperating with the first trigger member 1121, it can also reduce the inconvenience of arranging wires on the first trigger member 1121.

[0049] In some examples, when the first trigger part 1122a contacts the first trigger member 1121 and the second trigger part 1122b contacts the first trigger member 1121, the detection component 112 can output a path signal, that is, see Figure 5 shown in the figure. Only when the first trigger part 1122a contacts the first trigger member 1121 and the second trigger part 1122b contacts the first trigger member 1121 can a closed electronic switch 20 be formed, and thus the current can flow out from the first trigger part 1122a through the first trigger member 1121 to the second trigger part 1122b.

[0050] In some examples, when the first trigger part 1122a disconnects from the first trigger member 1121 or the second trigger part 1122b disconnects from the first trigger member 1121, the detection component 112 can output a trigger signal, that is, see Figure 6 , Figure 7 or Figure 8 shown in the figure, including: the first trigger member 1121 contacts the first trigger part 1122a and disconnects from the second trigger part 1122b, the first trigger member 1121 disconnects from the first trigger part 1122a and contacts the second trigger part 1122b, and the first trigger member 1121 disconnects from both the first trigger part 1122a and the second trigger part 1122b.

[0051] In some examples, the first trigger 1121 and the second trigger 1122 can be conductors, and the materials can include but are not limited to metals, graphite, or composite conductive materials, etc.

[0052] In some examples, multiple first triggers 1121 and multiple second triggers 1122 can cooperate to form multiple electronic switches 20 (see Figure 4 ). In some examples, multiple first triggers 1121 and multiple second triggers 1122 can cooperate to form multiple electronic switches 20, and the multiple electronic switches 20 can be connected in series or in parallel with each other. In this case, triggering through the multiple electronic switches 20 can improve the sensitivity of the detection component 112 of the measurement component 11 to contact the surface of the object to be measured during detection, thereby improving the measurement accuracy.

[0053] Figure 9 is a schematic structural diagram of the installation component 111 involved in the examples of the present disclosure. Figure 10 is a schematic diagram showing the structure and working principle of the magnetic control component 30 in the installation component 111 involved in the examples of the present disclosure. Figure 11 is a schematic diagram showing the working state of the magnetic control component 30 in the installation component 111 under the action of a preset magnetic field B. Figure 12 is a circuit diagram showing that the electronic switch 20 in the detection component 112 is connected in parallel with the magnetic control component 30 in the installation component 111. Among them, Figure 12 both the electronic switch 20 and the magnetic control component 30 have been simplified and equivalent processed. For example, the electronic switch 20 can be simplified and equivalent to a switch and a resistor, and the magnetic control component 30 can also be simplified and equivalent to a switch and a resistor. In addition, A in the figure represents the split point A between the installation component 111 and the detection component 112, that is, the installation component 111 and the detection component 112 can be split.

[0054] In some examples, as Figure 9 shown, the installation component 111 can include a magnetic control component 30. Specifically, the installation component 111 can include a magnetic control component 30 that is connected in parallel with the electronic switch 20 and has a switching function. For example, as Figure 12 shown, the magnetic control component 30 can be connected in parallel with the electronic switch 20 formed by the first trigger 1121 and the second trigger 1122 at both poles of the power supply.

[0055] In the present disclosure, the mounting assembly 111 can be configured such that when the magnetic control component 30 is turned on in response to a magnetic field change, the magnetic control component 30 outputs a conduction signal. In this case, the magnetic control component 30 in the mounting assembly 111 functions as a switch and is connected in parallel with the electronic switch 20 circuit in the detection component 112. When responding to a magnetic field change, the mounting assembly 111 can replace the electronic switch 20 to output a conduction signal, and thus when the detection component 112 is replaced, the measurement system can be made to think that the detection component 112 is not in the triggered measurement state (i.e., Figure 12 the case where the split A shown in

[0056] is disconnected). Thereby, the error rate of the measurement system can be reduced, that is, the problem of replacement failure of the measurement component 11 caused by the structural limitation of its own trigger component can be solved by means of hardware control, and thus the intelligence level of the measurement device can be improved. Figure 10 In some examples, as

[0057] shown, the magnetic control component 30 can include a first switch portion 301 and a second switch portion 302. In some examples, the first switch portion 301 and the second switch portion 302 can be connected to the power supply and can be closed and turned on in response to a magnetic field change. Figure 10 and 11 shown, when the mounting assembly 111 is far from the preset magnetic field B, that is, in the case shown in Figure 10 , when the magnetic control component 30 is not affected by the preset magnetic field B or does not exist in the preset magnetic field B, the first switch portion 301 and the second switch portion 302 are disconnected or not in contact; when the mounting assembly 111 is close to the preset magnetic field B, that is, in the case shown in Figure 11 , when the magnetic control component 30 is affected by the preset magnetic field B or exists in the preset magnetic field B, the first switch portion 301 and the second switch portion 302 are in contact or closed. In this case, through the first switch portion 301 and the second switch portion 302, the magnetic control component 30 can function as a switch, and by being connected in parallel with the electronic switch 20 circuit formed by the first trigger member 1121 and the second trigger member 1122, it can replace the electronic switch 20 and output a conduction signal under the action of a magnetic field when the detection component 112 of the measurement component 11 is replaced, that is, when the detection component 112 is replaced, the magnetic field can be used to control the circuit conduction so that the measurement system thinks that the detection component 112 is not in the triggered measurement state, and thus the error rate of the measurement system can be reduced.

[0058] In some examples, the magnetic control component 30 can be a magnetic control switch composed of a reed switch. In this case, the switching function of the reed switch can be utilized and its closing can be controlled under a preset magnetic field B to replace the electronic switch 20 formed by the first trigger member 1121 and the second trigger member 1122 when the measuring component 11 is replaced. Thus, the problem of replacement failure of the measuring component 11 caused by the structural limitation of its own trigger component can be solved through hardware control, thereby improving the intelligence level of the measuring device.

[0059] In some examples, the resistance value of the magnetic control component 30 can be equal to the equivalent resistance value after multiple electronic switches 20 are connected in series or in parallel. For example, as Figure 12 shown, when multiple electronic switches 20 can be equivalent to a switch and a resistor, and the magnetic control component 30 can also be equivalent to a switch and a resistor, the equivalent resistance value of multiple electronic switches 20 can be the same as the equivalent resistance value of the magnetic control component 30. In this case, multiple electronic switches 20 are connected in series or in parallel and then connected in parallel with the circuit of the magnetic control component 30, and the resistance value of the magnetic control component 30 is equal to the equivalent resistance value after multiple electronic switches 20 are connected in series or in parallel. When the detection component 112 of the measuring component 11 is replaced, the path signal that the magnetic control component 30 can output under the action of the magnetic field is the same as the path signal after multiple electronic switches 20 are connected in series or in parallel, improving the consistency of the output path signal. Thus, multiple electronic switches 20 can be replaced, and when the detection component 112 is replaced, the magnetic field is used to control the circuit path so that the measuring system believes that the detection component 112 is not in the triggered measurement state, thereby reducing the error rate of the measuring system.

[0060] In some examples, the detection component 112 and the mounting component 111 can be installed and disassembled by at least one of threading, magnetic attraction, or snap connection. In this case, it is convenient for the detection component 112 to be detachably installed on the mounting component 111, and the installation accuracy can be improved by adjusting the threading accuracy, magnetic attraction accuracy, or snap connection accuracy. Thus, the measurement accuracy of the measuring component 11 can be improved.

[0061] The following continues to describe the second aspect of the present disclosure in detail with reference to the accompanying drawings. Figure 13 FIG. shows a structural block diagram of the automatic replacement system 1 of the measuring component 11 involved in the present disclosure.

[0062] The second aspect of the present disclosure describes an automatic replacement system 1 for a measuring component 11. In some examples, as Figure 13 shown, the automatic replacement system 1 can include a measuring component 11, a driving device 12, and a placing device 13. In particular, the measuring component 11 involved in the second aspect of the present disclosure can refer to the measuring component 11 involved in any implementation manner of the first aspect of the present disclosure.

[0063] In some examples, the driving device 12 can be used to drive the measuring component 11 to move. Specifically, the driving device 12 can be used to drive the measuring component 11 to move to the placement device 13, and can place and replace the measuring component 11 in the placement device 13.

[0064] In some examples, the driving device 12 can be a driving mechanism of the measuring device, such as the main shaft and the sub-shaft of a coordinate measuring machine and other driving mechanisms. In some other examples, the driving device 12 can also be a robotic arm of other automated measuring devices, such as a multi-axis measuring device.

[0065] In some examples, the driving device 12 can be configured to drive the measuring component 11 to move to the placement device 13 and be located in a preset magnetic field B.

[0066] In some examples, the placement device 13 can form a preset magnetic field B. In some examples, the preset magnetic field B can be generated by a permanent magnet or a current device in the placement device 13.

[0067] In some examples, the placement device 13 can be configured to place and replace the detection component 112. In some examples, the placement device 13 can store a plurality of detection components 112. In some examples, the placement device 13 can automatically identify a plurality of detection components 112. In this case, an appropriate detection component 112 can be selected according to the measurement requirements and replaced to the measuring component 11, thereby improving the intelligence level of the measuring device.

[0068] In some examples, the placement device 13 can be a replacement mechanism provided in the measuring device for replacing the detection component 112 of the measuring component 11. For example, the placement device 13 can be a probe automatic replacement mechanism of a coordinate measuring machine. In some other examples, the placement device 13 can also be a replacement device independent of the measuring device for replacing the detection component 112 of the measuring component 11.

[0069] In some examples, the measuring component 11 can be a component based on a measurement method triggered by the electronic switch 20. In some examples, the measuring component 11 can include a mounting component 111 and a detection component 112. Specifically, the measuring component 11 can include a mounting component 111 and a detection component 112 detachably mounted on the mounting component 111 and used to contact the surface of the object to be measured and output a trigger signal at the same time.

[0070] In some examples, the detection component 112 can include a probe 1123, a first trigger 1121, and a second trigger 1122. Specifically, the detection component 112 can include a probe 1123 for contacting the surface of the object to be measured, a first trigger 1121 connected to the probe 1123, and a second trigger 1122 that cooperates with the first trigger 1121 to form the electronic switch 20.

[0071] In some examples, the detection component 112 can be configured to output a path signal when the first trigger 1121 contacts the second trigger 1122, and output a trigger signal when the probe 1123 contacts the surface of the object to be measured and the first trigger 1121 is not in contact with the second trigger 1122. In this case, the detection component 112 forms an electronic switch 20 through the cooperation of the first trigger 1121 and the second trigger 1122, and the first trigger 1121 is connected to the probe 1123. When the probe 1123 does not contact 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 a closed state, and the detection component 112 can output a path signal. When the probe 1123 contacts the surface of the object to be measured, the first trigger 1121 and the second trigger 1122 are disconnected, that is, the electronic switch 20 is opened through the probe 1123 connected to the first trigger 1121, and the detection component 112 can output a trigger signal. Thus, it is convenient for the measuring device to detect through the detection component 112 by using a contact measurement method to obtain information such as the size, shape or position of the object to be measured.

[0072] In some examples, the mounting component 111 can include a magnetic control component 30 that is connected in parallel with the circuit of the electronic switch 20 and has a switching function.

[0073] In some examples, the mounting component 111 can be configured to conduct the magnetic control component 30 and output a path signal when the magnetic control component 30 responds to a preset magnetic field B. In this case, the magnetic control component 30 in the mounting component 111 has a switching function and is connected in parallel with the electronic switch 20 in the detection component 112. When responding to the preset magnetic field B of the placement device 13, the mounting component 111 can replace the electronic switch 20 to output a path signal, and further can make the measurement system think that the detection component 112 is not in a triggered measurement state when the detection component 112 is replaced, that is, moved to the placement device 13. Thus, the error rate recognized by the measurement system can be reduced.

[0074] In the second aspect of the present disclosure, by driving the measuring component 11 to move into the placement device 13 with a preset magnetic field B through the driving device 12, the detection component 112 detachably mounted on the mounting component 111 in the measuring component 11 can be replaced in the placement device 13. Since the magnetic control component 30 in the mounting component 111 has a switching function and is connected in parallel with the electronic switch 20 circuit in the detection component 112, when responding to the preset magnetic field B of the placement device 13, the mounting component 111 can replace the electronic switch 20 and output a path signal, so that when the detection component 112 is replaced, that is, moved to the placement device 13, the measurement system can be made to think that the detection component 112 is not in the triggered measurement state. Thus, the error rate recognized by the measurement system can be reduced, that is, the problem of replacement failure of the measuring component 11 caused by the structural limitation of its own trigger component can be solved by means of hardware control, and thus the intelligence level of the measuring device can be improved.

[0075] In some examples, the magnetic control component 30 may include a first switch portion 301 and a second switch portion 302.

[0076] In some examples, the mounting component 111 may also be configured such that when approaching the preset magnetic field B, the first switch portion 301 contacts the second switch portion 302 and outputs a path signal, and when away from the preset magnetic field B, the first switch portion 301 does not contact the second switch portion 302. In this case, through the first switch portion 301 and the second switch portion 302, the magnetic control component 30 can have a switching function, and by being connected in parallel with the electronic switch 20 circuit formed by the first trigger member 1121 and the second trigger member 1122, it can replace the electronic switch 20 and output a path signal under the action of the magnetic field when replacing the detection component 112 of the measuring component 11, that is, when the detection component 112 is replaced, the measurement system can be made to think that the detection component 112 is not in the triggered measurement state by controlling the circuit path with the magnetic field, and thus the error rate of the measurement system can be reduced.

[0077] In some examples, a plurality of first trigger members 1121 and a plurality of second trigger members 1122 can cooperate to form a plurality of electronic switches 20, and the plurality of electronic switches 20 can be connected in series or in parallel with each other. In this case, by triggering with the plurality of electronic switches 20, the sensitivity of the detection component 112 of the measuring component 11 to contact the surface of the object to be measured during detection can be improved, and thus the measurement accuracy can be improved.

[0078] In some examples, the resistance value of the magnetic control component 30 can be equal to the equivalent resistance value after a plurality of electronic switches 20 are connected in series or in parallel with each other. In this case, after a plurality of electronic switches 20 are connected in series or in parallel with each other and then connected in parallel with the circuit of the magnetic control component 30, and the resistance value of the magnetic control component 30 is equal to the equivalent resistance value after a plurality of electronic switches 20 are connected in series or in parallel with each other, when the detection component 112 of the measurement component 11 is replaced, the path signal that the magnetic control component 30 can output under the action of the magnetic field is the same as the path signal after a plurality of electronic switches 20 are connected in series or in parallel with each other, improving the consistency of the output path signal. Thus, a plurality of electronic switches 20 can be replaced, and when the detection component 112 is replaced, the magnetic field is used to control the circuit path so that the measurement system believes that the detection component 112 is not in the triggered measurement state, thereby reducing the error rate of the measurement system.

[0079] According to the present disclosure, a measurement component 11 and its automatic replacement system 1 can be provided, which can solve the problem of replacement failure of the measurement component 11 due to the structural limitation of its own trigger component through a hardware control method, thereby improving the intelligence level of the measurement device.

Those skilled in the art can make deformations and variations to the present disclosure according to needs without departing from the essence and scope of the present disclosure, and these deformations and variations all fall within the scope of the present disclosure.
