Description

Technical Field

[0001] The utility model relates to the field of measuring tooling, specifically a measuring mechanism and a measuring system. Background Art

[0002] In the prior art, a patent document with the title of surface shape sensor and application number 200910075717.1 is provided; in this patent document, a technical solution of arranging a plurality of sub-sensors on a sensor housing and using a filler between the plurality of sub-sensors is specifically adopted, forming a technical effect that a plane or a curved surface can be detected at one time.

[0003] However, in the above prior art, since the plurality of sub-sensors are fixed relative to the sensor housing, if the size of the detected surface of the detection object conforms to the size of the contour formed by the plurality of sub-sensors of this surface shape sensor, then this surface shape sensor can detect the detected surface. However, if the size of the detected surface of the detection object does not conform to the size of the contour formed by the plurality of sub-sensors of this surface shape sensor, then this surface shape sensor cannot detect the detected surface. The following is an example for illustration;

[0004] For example, the area of the detected surface is much smaller than the area of the contour of the plurality of sub-sensors, so that at least one sub-sensor cannot contact the detected surface;

[0005] Another example is that the contour of the detected surface is a rectangle, the contour of the plurality of sub-sensors is a rectangle, the length of the contour of the detected surface conforms to the length of the contour of the plurality of sub-sensors, but the width of the contour of the detected surface is smaller than the width of the contour of the plurality of sub-sensors, so that at least one sub-sensor cannot contact the detected surface;

[0006] Through the above two examples, it can be shown that in the surface shape sensor of the prior art, since the plurality of sub-sensors are fixed relative to the sensor housing, the range of the detection object of the same type of surface shape sensor is relatively small; in other words, when an important change occurs in the detected surface of the detection object, making the detected surface not conform to the contour of the plurality of sub-sensors, this surface shape sensor cannot detect the detection object after the change; the essential reason for the above problem is that the plurality of sub-sensors cannot change their positions relative to each other.

[0007] Therefore, how to change the positions of the plurality of sub-sensors relative to each other becomes a technical problem to be solved. Summary of the Utility Model

[0008] To solve the technical problem of how to change the positions of the plurality of sub-sensors relative to each other in the prior art, the utility model provides a measuring mechanism and a measuring system.

[0071] Example 1:

[0072] In this example, a measuring mechanism is provided to solve the technical problem of how to change the positions of multiple sub-sensors relative to each other.

[0073] Specifically, refer to Figure 1 or Figure 3 or Figure 5 , the measuring mechanism 1 in this example includes multiple probes 100, a bracket 200, and an adjustment mechanism 300;

[0074] The adjustment mechanism 300 is arranged on the bracket 200;

[0075] The adjustment mechanism 300 includes a first movement path L1, a second movement path L2, a third movement path L3, and at least four moving parts 301. The first movement path L1 and the second movement path L2 are parallel to each other. The third movement path L3 is perpendicular to both the first movement path L1 and the second movement path L2, and the third movement path L3 is parallel to the plane determined by the first movement path L1 and the second movement path L2;

[0076] All the moving parts 301 are divided into a first group of moving components and a second group of moving components. The number of moving parts 301 included in the first group of moving components is the first quantity, and the number of moving parts 301 included in the second group of moving components is the second quantity. The first quantity and the second quantity are the same;

[0077] The distance between any two moving parts 301 of the first group of moving components is configured to be adjustable through the first movement path L1;

[0078] The distance between any two moving parts 301 of the second group of moving components is configured to be adjustable through the second movement path L2;

[0079] The distance between the first group of moving components and the second group of moving components is configured to be adjustable through the third movement path L3;

[0080] The multiple probes 100 are configured to be parallel to each other, point in the same direction, and the tip parts of the multiple probes 100 are coplanar. Among them, at least one probe 100 is defined as the central axis probe 101, and the remaining probes 100 are defined as edge probes 102. The central axis probe 101 is arranged on the bracket 200, and at least one edge probe 102 is arranged on each moving part 301. The central axis probe 101 is located between all the edge probes 102.

[0081] Refer to Figure 1 , Figure 2 , Figure 7 or Figure 9, in the measuring mechanism 1 of this embodiment, its adjusting mechanism 300 is used to adjust the spacing between at least four moving parts 301, so that the positions of the four moving parts 301 relative to each other are changed.

[0082] Specifically, the four moving parts 301 are assigned to a first group of moving components and a second group of moving components, and the number of the two groups of moving components is the same; for example, if the adjusting mechanism 300 of this embodiment is provided with four moving parts 301, then each group of moving components includes two moving parts 301 respectively; another example: if the adjusting mechanism 300 of this embodiment is provided with six moving parts 301, then each group of moving components includes three moving parts 301 respectively; and so on, each group of moving components can be four, five or six moving parts 301 respectively.

[0083] In this embodiment, the movement path of each moving part 301 is restricted by the adjusting mechanism 300; specifically, see Figure 5 , the adjusting mechanism 300 is provided with a first movement path L1, a second movement path L2 and a third movement path L3, and the movement path of each moving part 301 can be simply understood as being restricted by at least one of the first movement path L1, the second movement path L2 and the third movement path L3;

[0084] The first movement path L1, the second movement path L2 and the third movement path L3 are respectively restricted to be linear movement paths. Thus, when any moving part 301 is restricted to move along the first movement path L1 or the second movement path L2 or the third movement path L3, the actual movement path of the moving part 301 is a straight line path.

[0085] Assume that the first group of moving components includes two moving parts 301. Then, the movement paths of the two moving parts 301 are restricted to the first movement path L1. In other words, the spacing between the two moving parts 301 can be changed through the first movement path L1; similarly, the spacing between the two moving parts 301 of the second group of moving components can also be changed through the second movement path L2; however, the movement paths of the first group of moving components and the second group of moving components are restricted to the third movement path L3. In other words, the spacing between the first group of moving components and the second group of moving components can be changed through the third movement path L3, resulting in the spacing between the two moving parts 301 of the first group of moving components being changed relative to the spacing between the two moving parts 301 of the second group of moving components through the third movement path L3.

[0086] Assume that the first set of moving components includes three moving parts 301. Then, the movement paths of the three moving parts 301 are restricted to the first movement path L1. In other words, the distance between any two of the three moving parts 301 can be changed through the first movement path L1. Similarly, for the three moving parts 301 of the second set of moving components, the distance between any two of them can be changed through the second movement path L2. However, the movement paths of the first set of moving components and the second set of moving components are restricted to the third movement path L3. In other words, the distance between the first set of moving components and the second set of moving components can be changed through the third movement path L3, resulting in the distance between the three moving parts 301 of the first set of moving components relative to the three moving components of the second set of moving components being changed through the third movement path L3.

[0087] It should be understood that for the solutions where the first set of moving components and the second set of moving components respectively include four or five or six moving parts 301, the effects of position change achieved by the first movement path L1, the second movement path L2, and the third movement path L3 are the same as or similar to those of the solutions where the first set of moving components and the second set of moving components respectively include two or three moving parts 301. Therefore, they will not be elaborated here.

[0088] See Figure 1 , in this embodiment, the adjusting mechanism 300 is arranged on the bracket 200. Since the movement paths of all the moving parts 301 are respectively restricted by the first movement path L1, the second movement path L2, and the third movement path L3, all the moving parts 301 form a relatively fixed state relative to the bracket 200. In this relatively fixed state, any one of the moving parts 301 cannot be separated from the bracket 200.

[0089] See Figure 1 , Figure 2 , Figure 7 or Figure 9 , in this embodiment, the multiple probes 100 are configured as the central axis probe 101 and the edge probe 102. Among them, when the central axis probe 101 actually detects the object to be measured, it can contact the position of the central axis of the detected surface of the object to be measured. Correspondingly, when the edge probe 102 actually detects the object to be measured, it can contact the position near the edge of the detected surface of the object to be measured;

[0090] It should be understood that see Figure 4 , the specific structure of the probe 100 is common knowledge known to those skilled in the art and will not be elaborated here.

[0091] The number of the central axis probes 101 can be 1, 2, or 3, and the number of the edge probes 102 is at least 4; the positional relationship of the central axis probes 101 relative to the edge probes 102 is that all the central axis probes 101 are restricted between all the edge probes 102;

[0092] For example, if there is 1 central axis probe 101 and 4 edge probes 102, then the 1 central axis probe 101 is restricted between the contours formed by the 4 edge probes 102;

[0093] For example, if there are 2 central axis probes 101 and 4 edge probes 102, then the 2 central axis probes 101 are restricted between the contours formed by the 4 edge probes 102;

[0094] For example, if there are 2 central axis probes 101 and 6 edge probes 102, then the 2 central axis probes 101 are restricted between the contours formed by the 6 edge probes 102;

[0095] For example, if there are 3 central axis probes 101 and 6 edge probes 102, then the 3 central axis probes 101 are restricted between the contours formed by the 6 edge probes 102;

[0096] And so on, as long as all the central axis probes 101 are restricted between the contours formed by all the edge probes 102.

[0097] Those skilled in the art should understand that during the actual detection process using multiple probes 100, the distance between any two probes 100 should be restricted within a reasonable range to avoid deviation in the detection results;

[0098] Assume that the reasonable distance between two probes 100 is 100 mm. Then, if the actual distance between two probes 100 is greater than 100 mm, the probability of deviation in the detection results increases.

[0099] In this embodiment, considering that the distance between two edge probes 102 may exceed the reasonable distance during the actual detection process, the central axis probe 101 is provided. By using the positional relationship that the central axis probe 101 is restricted between all the edge probes 102, when the distance between two of the edge probes 102 has exceeded the reasonable distance, the central axis probe 101 can be configured to have a reasonable distance relative to these two edge probes 102. That is, the distance between the first edge probe 102 and the central axis probe 101 is configured to be a reasonable distance, and the distance between the second edge probe 102 and the central axis probe 101 is configured to be a reasonable distance; and so on. When the distances between multiple edge probes 102 exceed the reasonable distance, the probability of deviation in actual detection can be reduced by setting 1 or 2 or 3 central axis probes 101.

[0100] In this embodiment, the central axis probe 101 is directly connected to the bracket 200; and on any one of the moving parts 301, at least one edge probe 102 is respectively provided, so that any one of the edge probes 102 can form a movable state relative to the bracket 200 through the connected moving part 301. Then, when two adjacent moving parts 301 approach or move away from each other, the edge probes 102 on the two moving parts 301 also approach or move away from each other.

[0101] In the process of actually using the measuring mechanism 1 of this embodiment to detect two measured objects with different sizes, if the contour formed by multiple edge probes 102 can match the detected surface of the first measured object but does not match the detected surface of the second measured object, then by adjusting the positions of all the moving parts 301 relative to each other, the contour formed by multiple edge probes 102 can be changed, so that after adjustment, the multiple edge probes 102 can match the detected surface of the second measured object;

[0102] Specifically, the measuring mechanism 1 of this embodiment can be actually used for measurement in the following scenarios;

[0103] Scenario 1: The detected surface of the first measured object is a first rectangular plane, and the detected surface of the second measured object is a second rectangular plane. The length and width of the second rectangular plane are respectively smaller than the length and width of the first rectangular plane. At the same time, the measuring mechanism 1 is provided with four moving parts 301, and one edge probe 102 is provided on each moving part 301, and a central axis probe 101 is provided between the four edge probes 102;

[0104] In Scenario 1, if in the initial state, the contour formed by the four edge probes 102 matches the first rectangular plane, then during the process of the four edge probes 102 detecting the second rectangular plane, it is possible that the four edge probes 102 or some of the edge probes 102 cannot contact the second rectangular plane. At this time, by adjusting the positions of the four moving components 301, the distance between the two moving components 301 along the first movement path L1 is shortened, and the distance between the two moving components 301 along the second movement path L2 is shortened. Furthermore, the distance between the first set of moving components (specifically, the two moving components 301 along the first movement path L1) and the second set of moving components (specifically, the two moving components 301 along the second movement path L2) is shortened. After adjusting in this way, the contour formed by the four edge probes 102 matches the second rectangular plane, and then the four edge probes 102 can respectively contact the second rectangular plane.

[0105] Scenario 2, the setting conditions of Scenario 2 are the same as those of the aforementioned Scenario 1. The difference is that if in the initial state, the contour formed by the four edge probes 102 matches the second rectangular plane, then during the process of the four edge probes 102 detecting the first rectangular plane, it is possible that the four edge probes 102 or some of the edge probes 102 cannot contact the first rectangular plane. At this time, by adjusting the positions of the four moving components 301, the distance between the two moving components 301 along the first movement path L1 is increased, and the distance between the two moving components 301 along the second movement path L2 is increased. Furthermore, the distance between the first set of moving components (specifically, the two moving components 301 along the first movement path L1) and the second set of moving components (specifically, the two moving components 301 along the second movement path L2) is increased. After adjusting in this way, the contour formed by the four edge probes 102 matches the first rectangular plane, and then the four edge probes 102 can respectively contact the first rectangular plane.

[0106] Scenario 3, the detected surface of the first object to be measured is the first rectangular plane, the detected surface of the second object to be measured is the second rectangular plane. The length of the second rectangular plane is less than the length of the first rectangular plane, and the width of the second rectangular plane is the same as the width of the first rectangular plane. At the same time, the measuring mechanism 1 is provided with four moving components 301, each moving component 301 is provided with an edge probe 102, and a central axis probe 101 is arranged between the four edge probes 102;

[0107] If, in the initial state, the contour formed by the four edge probes 102 matches the first rectangular plane, then, during the process of the four edge probes 102 detecting the second rectangular plane, it is possible that two of the four edge probes 102 cannot contact the second rectangular plane. At this time, by adjusting the positions of the four moving components 301, the distance between the two moving components 301 along the first movement path L1 is shortened, and the distance between the two moving components 301 along the second movement path L2 is shortened, and the distance between the first set of moving components (specifically, the two moving components 301 along the first movement path L1) and the second set of moving components (specifically, the two moving components 301 along the second movement path L2) is kept unchanged. After adjusting in this way, the contour formed by the four edge probes 102 matches the second rectangular plane, and then the four edge probes 102 can respectively contact the second rectangular plane.

[0108] Scenario 4: The setup conditions of Scenario 4 are similar to those of the aforementioned Scenario 3, with the difference being that the length of the first rectangular plane is the same as the length of the second rectangular plane, while the width of the first rectangular plane is different from the width of the second rectangular plane. If, in the initial state, the contour formed by the four edge probes 102 matches the first rectangular plane, then, during the process of the four edge probes 102 detecting the second rectangular plane, it is possible that two of the four edge probes 102 cannot contact the second rectangular plane. At this time, by adjusting the positions of the four moving components 301, the distance between the two moving components 301 along the first movement path L1 remains unchanged, and the distance between the two moving components 301 along the second movement path L2 remains unchanged. However, the distance between the first set of moving components (specifically, the two moving components 301 along the first movement path L1) and the second set of moving components (specifically, the two moving components 301 along the second movement path L2) is increased or shortened. Thus, after adjusting in this way, the contour formed by the four edge probes 102 matches the second rectangular plane, and then the four edge probes 102 can respectively contact the second rectangular plane.

[0109] Scenario 5: There are two detected surfaces for the first object to be measured, namely the first rectangular plane and the second rectangular plane. There is a height difference between the first rectangular plane and the second rectangular plane. The maximum total length of the first rectangular plane and the second rectangular plane is the first total length, and the maximum width of either the first rectangular plane or the second rectangular plane is the first total width. There are two detected surfaces for the second object to be measured, namely the third rectangular plane and the fourth rectangular plane. There is a height difference between the third rectangular plane and the fourth rectangular plane. The maximum total length of the third rectangular plane and the fourth rectangular plane is the second total length, and the maximum width of either the third rectangular plane or the fourth rectangular plane is the second total width. The first total length is greater than the second total length, and the first total width is greater than the second total width.

[0110] In Scenario 5, under the condition that the planar height differences between the two objects under test are the same, if initially, the contour formed by the four edge probes 102 matches the first rectangular plane and the second rectangular plane, where two of the edge probes 102 are in contact with the first rectangular plane and the other two edge probes 102 are in contact with the second rectangular plane, then during the process of the four edge probes 102 detecting the third rectangular plane and the fourth rectangular plane, it is possible that at least one of the probes 100 cannot contact the third rectangular plane or the fourth rectangular plane. At this time, the distance between the four moving components 301 can be shortened respectively through the adjustment method in Scenario 1 described above to achieve the effect that the four edge probes 102 match the third rectangular plane and the fourth rectangular plane, which will not be elaborated here.

[0111] Scenario 6. The setting conditions of Scenario 6 are similar to those of Scenario 5. The difference is that in Scenario 6, the number of detected surfaces of the object to be detected is two, namely the first rectangular plane and the second rectangular plane. The first rectangular plane and the second rectangular plane are coplanar, but there is a gap between the first rectangular plane and the second rectangular plane, and a non-detection plane is also provided between the first rectangular plane and the second rectangular plane; correspondingly, the number of detected surfaces of the second object to be detected is two, namely the third rectangular plane and the fourth rectangular plane. The third rectangular plane and the fourth rectangular plane are coaxial, but there is a gap between the third rectangular plane and the fourth rectangular plane, and a non-detection plane is also provided between the third rectangular plane and the fourth rectangular plane;

[0112] Among the four edge probes 102, two of the edge probes 102 are used to detect the first rectangular plane, and the other two edge probes 102 are used to detect the second rectangular plane. Then during the process of the four edge probes 102 detecting the third rectangular plane and the fourth rectangular plane, it is possible that at least one of the probes 100 cannot contact the third rectangular plane or the fourth rectangular plane. At this time, the distance between the four moving components 301 can be shortened respectively through the adjustment method in Scenario 1 described above to achieve the effect that the four edge probes 102 match the third rectangular plane and the fourth rectangular plane, which will not be elaborated here.

[0113] It should be understood that, in addition to the setting conditions in Scenarios 1 to 6 described above, in other scenarios, the measuring mechanism 1 of this embodiment can also be used for detection; in other scenarios, the surface to be detected can be a regular curved surface, such as an arc surface, a circular surface, a sine curved surface, etc.; in other scenarios, the number of moving parts 301 can be six, eight or ten; in other scenarios, the number of edge probes 102 on each moving part 301 can be two or three, or the number of central axis probes 101 is two or three; under the conditions in the other scenarios listed above, the adjustment can be made respectively through the adjustment methods in Scenarios 1 to 6 described above, which will not be elaborated here.

[0114] In the measuring mechanism 1 of this embodiment, by setting at least four moving parts 301 and restricting the movement paths of the four moving parts 301 to the first movement path L1, the second movement path L2 and the third movement path L3, the distance between the edge probes 102 located on the four moving parts 301 can be adjusted, thus solving the technical problem in the prior art of how to change the positions of multiple sub-sensors relative to each other.

[0115] Furthermore, this embodiment provides the structure of the first preferred adjustment mechanism 300, specifically:

[0116] See Figure 2 or Figure 3 or Figure 7 , in the measuring mechanism 1 of this embodiment, the adjustment mechanism 300 includes a first bidirectional lead screw assembly 310, a second bidirectional lead screw assembly 320 and a third lead screw assembly 330;

[0117] The path of the bidirectional lead screw of the first bidirectional lead screw assembly 310 driving the ball is the first movement path L1, and the two balls of the first bidirectional lead screw assembly 310 are respectively the moving parts 301, wherein the two balls of the first bidirectional lead screw assembly 310 are configured as the first group of moving components;

[0118] The path of the second bidirectional lead screw assembly 320 driving the ball is the second movement path L2, and the two balls of the second bidirectional lead screw assembly are respectively the moving parts 301, wherein the two balls are configured as the second group of moving components;

[0119] The path of the lead screw of the third lead screw assembly 330 driving the ball is the third movement path L3, and the ball of the third lead screw assembly 330 is used to connect the first bidirectional lead screw assembly 310 or the second bidirectional lead screw assembly 320.

[0120] Among them, the two-way lead screw of the first two-way lead screw assembly 310 has a left-handed thread and a right-handed thread. A first ball is provided on the left-handed thread, and a second ball is provided on the right-handed thread. The movement path of the first ball driven by the left-handed thread is path A, and the movement path of the second ball driven by the right-handed thread is path B. Thus, the first movement path L1 is actually the sum of path A and path B;

[0121] The structure of the second two-way lead screw assembly 320 is the same as that of the first two-way lead screw assembly 310, so that the first movement path L1 and the second movement path L2 have the same essential structure, which will not be elaborated here.

[0122] The lead screw of the third lead screw assembly 330 has only a left-handed thread or a right-handed thread. The thread of the lead screw drives a ball. The movement path of the ball driven by the third lead screw assembly 330 is the third movement path L3; One of the aforementioned first two-way lead screw assembly 310 and second two-way lead screw assembly 320 is connected to the ball of the third lead screw assembly 330, and the remaining two-way lead screw assembly is connected to the bracket 200.

[0123] Furthermore, in the structure of the aforementioned first preferred adjustment mechanism 300, the following bracket 200 is preferably adopted, specifically:

[0124] See Figure 2 、 Figure 6 or Figure 8 , the bracket 200 includes a first plate member 201, a second plate member 202 and a third plate member 203. The first plate member 201 and the second plate member 202 are connected to the third plate member 203 in parallel;

[0125] Between the first plate member 201 and the second plate member 202, the third lead screw assembly 330 is connected to the first plate member 201;

[0126] Outside the first plate member 201 and the second plate member 202, the first two-way lead screw assembly 310 or the second two-way lead screw assembly 320 is connected to the second plate member 202;

[0127] The bracket 200 further includes a fourth plate member 204. The fourth plate member 204 includes a fourth connecting portion 001 and a fourth deflecting portion 002 integrally formed. The fourth connecting portion 001 and the fourth deflecting portion 002 form an angle. The fourth connecting portion 001 is connected to the third plate member 203, and the central probe 101 is installed on the fourth deflecting portion 002.

[0128] It should be understood that the connection mode between the central axis probe 101 and the fourth direction-changing part 002 (the fourth plate 204) can adopt the connection mode of the prior art. For example, a positioning sleeve with an external thread and a nut are used to set the central axis probe 101 at the through hole of the fourth direction-changing part 202. The central axis probe 101 penetrates the through hole, and the central axis probe 101 is in interference fit or spline fit with the positioning sleeve, and the central axis probe is clamped at the through hole of the fourth direction-changing part 202 by the nut and the protrusion on the positioning sleeve.

[0129] It should be understood that the connection mode between the edge probe 102 and the moving part 301 can adopt various connection modes in the prior art. For example, the connection mode between the aforementioned central axis probe 101 and the fourth direction-changing part 002 (the fourth plate 204), only a plate with a through hole, a positioning sleeve with an external thread and a nut need to be added between the edge probe 102 and the moving part 3014.

[0130] Among them, the third plate 203 serves as the bottom plate, the first plate 201 and the second plate 202 serve as vertical plates respectively. The length of the first plate 201 is greater than that of the second plate 202, and the first plate 201 and the second plate 202 are parallel to each other. A receiving cavity is formed between the first plate 201 and the second plate 202; specifically, the third lead screw assembly 330 further includes a motor and two positioning plates. Among them, the two positioning plates are respectively arranged on the first plate 201, and the lead screw of the third lead screw assembly 330 forms a rotating pair with the two positioning plates respectively, and the motor is accommodated in the aforementioned receiving cavity; adopting such a setting method can ensure that the balls of the third lead screw assembly 330 are not affected by the first plate 201 and the second plate 202, so that the first bidirectional lead screw assembly 310 or the second bidirectional lead screw assembly 320 connected to the balls of the third lead screw assembly 330 is not blocked by the first plate 201 and the second plate 202 during the movement process.

[0131] It should be understood that side plates 205 should be arranged between the first plate 201 and the second plate 202. The number of side plates 205 is two. Two sides of any one side plate 205 are respectively connected to one side of the first plate 201 and one side of the second plate 202, and one side of any one side plate 205 is connected to one side of the third plate 203.

[0132] See Figure 6 Or Figure 8, the fourth connecting portion 001 of the fourth plate member 204 is connected to the third plate member 203. The length of the fourth connecting portion 001 forms a spacing between the fourth deflecting portion 002 and the third plate member 203, and this spacing is greater than the thickness or height of the first double lead screw assembly 310 or the second double lead screw assembly 320. For example, if the aforementioned third movement path L3 is configured to be set along the horizontal direction, then this spacing is greater than the vertical height of the first double lead screw assembly 310 or the second double lead screw assembly 320; or, if the aforementioned third movement path L3 is configured to be set along the vertical direction, then this spacing is greater than the horizontal thickness of the first double lead screw assembly 310 or the second double lead screw assembly 320; from the perspective of a person's line of sight, the fourth deflecting portion 002 can be observed outside the first double lead screw assembly 310 and the second double lead screw assembly 320, and the fourth deflecting portion 002 is located between all the moving parts 301;

[0133] The central axis probe 101 is arranged on the fourth deflecting portion 002. During the actual application of the measuring mechanism 1 of this embodiment, the fourth plate member 204 remains stationary relative to the first plate member 201 and the third plate member 203, while all the moving parts 301 are in a movable state relative to the first plate member 201. Therefore, when any one of the moving parts 301 moves relative to the first plate member 201 and the third plate member 203, the edge probe 102 located on this moving part 301 respectively forms a movement effect of increasing or decreasing the spacing relative to the central axis probe 101 located on the fourth plate member 204.

[0134] It should be understood that, referring to Figure 2 , if the first double lead screw assembly 310 is arranged on the second plate member 202, then the second double lead screw assembly 320 should be connected to the balls of the third lead screw assembly 330 through the fifth plate member 206; the first double lead screw assembly 310 further includes two positioning plates and a motor. The two positioning plates of the first double lead screw assembly 310 are connected to the second plate member 202 in parallel. The double lead screws of the first double lead screw assembly 310 respectively form a rotating pair with the two positioning plates of the first double lead screw assembly 310. The motor shaft of the motor of the first double lead screw assembly 310 is connected to one end of the double lead screw of the first double lead screw assembly 310 through a coupling, and the outer shell of the motor is connected to one of the positioning plates through bolts; the structure of the second double lead screw assembly 320 is the same as that of the first double lead screw assembly 310, the difference being that the second double lead screw assembly 320 is connected to the fifth plate member 206, and the rest will not be elaborated here;

[0135] It should be understood that if the second double lead screw assembly 320 is provided on the second plate member 202 (not shown in the figure), then the first double lead screw assembly 310 should be connected to the ball of the third lead screw assembly 330 through the fifth plate member 206; the connection manner between the second double lead screw assembly 320 and the second plate member 202 here is the same as the connection manner between the aforementioned first double lead screw assembly 310 and the second plate member 202, and the connection manner between the first double lead screw assembly 310 and the second plate member 202 here is the same as the connection manner between the aforementioned second double lead screw assembly 320 and the second plate member 202, which will not be elaborated here.

[0136] It should be understood that if a gap is formed between the ball of the third lead screw assembly 330 and the second plate member 202, then a heightening structure or thickening structure, such as a spacer block, should be provided between the ball of the third lead screw assembly 330 and the aforementioned fifth plate member 206. By providing the spacer block, the second plate member 202 and the fifth plate member 206 can be configured in the same plane.

[0137] Furthermore, the present embodiment provides a second preferred structure of the adjusting mechanism 300, specifically:

[0138] See Figure 9 , the adjusting mechanism 300 includes a first linear motor 340, a second linear motor 350, and a fourth double lead screw assembly 360;

[0139] The stator of the first linear motor 340, the driving path of its mover is the first motion path L1, and the three movers of the first linear motor 340 are respectively the moving components 301. Among them, the three movers of the first linear motor 340 are configured as the first group of motion components;

[0140] The stator of the second linear motor 350, the driving path of its mover is the second motion path L2, and the three movers of the second linear motor 350 are respectively the moving components 301. Among them, the three movers of the second linear motor 350 are configured as the second group of motion components;

[0141] The path for the double lead screw of the fourth double lead screw assembly 360 to drive the ball is the third motion path L3. The fourth double lead screw assembly 360 is provided with two balls, and the first linear motor 340 and the second linear motor 350 are respectively connected to one of the balls of the fourth double lead screw assembly 360.

[0142] It should be understood that the structure and working principle of the linear motor are common general knowledge known to those skilled in the art; the linear motor can be provided with one, two, three, or more movers, and each mover is configured as a movable structure relative to the stator. In other words, the stator can drive any one of the movers simultaneously or at different times, which is common general knowledge known to those skilled in the art.

[0143] The first linear motor 340 is provided with three movers. Among them, the distance between any two adjacent movers is an adjustable distance. Thus, the distance between the edge probes 102 provided on any two movers can be adjusted;

[0144] Similarly, the second linear motor 350 is provided with three movers. The distance between any two adjacent movers of the second linear motor 350 is an adjustable distance. Thus, the distance between the edge probes 102 on any two movers can be adjusted.

[0145] The structure of the fourth bidirectional lead screw assembly 360 is the same as that of the foregoing first bidirectional lead screw assembly 310 and second bidirectional lead screw assembly 320, and will not be described in detail here;

[0146] The first linear motor 340 is integrally connected to one of the balls of the fourth bidirectional lead screw assembly 360, and the second linear motor 350 is integrally connected to the other ball of the bidirectional lead screw assembly. Thus, when the distance between the two balls of the fourth bidirectional lead screw assembly 360 increases or decreases, the distance between the first linear motor 340 and the second linear motor 350 increases or decreases.

[0147] Furthermore, for the foregoing second preferred adjustment mechanism 300, the bracket 200 in this embodiment preferably adopts the following technical solution, specifically:

[0148] See Figure 11 , the bracket 200 includes a support plate 211, two slide rails 212 and four sliders 213;

[0149] The two slide rails 212 are arranged in parallel with a distance on the mounting surface of the support plate 211, and two sliders 213 are respectively arranged on any one of the slide rails 212;

[0150] The fourth bidirectional lead screw assembly 360 is arranged on the mounting surface. The fourth bidirectional lead screw assembly 360 is located between the two slide rails 212, and the axis line of the bidirectional lead screw of the fourth bidirectional lead screw assembly 360 is parallel to the two slide rails 212;

[0151] One of the sliders 213 located on any one of the slide rails 212 is connected to the first linear motor 340, and the other slider 213 located on any one of the slide rails 212 is connected to the second linear motor 350.

[0152] From the perspective of the first linear motor 340, the first linear motor 340 is respectively connected to one of the sliders 213 located on the first slide rail 212, one of the sliders 213 located on the second slide rail 212, and one of the balls of the fourth bidirectional lead screw assembly 360. When the fourth bidirectional lead screw assembly 360 drives the ball to make a linear motion, the first linear motor 340 respectively drives the two sliders 213 connected thereto to generate a motion trend. Under this motion trend, any one of the sliders 213 respectively generates a linear motion relative to its corresponding slide rail 212;

[0153] From the perspective of the second linear motor 350, the second linear motor 350 is respectively connected to the other one of the sliders 213 located on the first slide rail 212, the other one of the sliders 213 located on the second slide rail 212, and the other one of the balls of the fourth bidirectional lead screw assembly 360. When the fourth bidirectional lead screw assembly 360 drives the ball to make a linear motion, the second linear motor 350 respectively drives the two sliders 213 connected thereto to generate a motion trend. Under this motion trend, any one of the sliders 213 respectively generates a linear motion relative to its corresponding slide rail 212;

[0154] If the fourth bidirectional lead screw assembly 360 is regarded as the power source for driving the first linear motor 340 and the second linear motor 350, then the two slide rails 212 and the four sliders 213 are regarded as the guiding structure and the supporting structure of the first linear motor 340 and the second linear motor 350. From the perspective of the two slide rails 212 and the four sliders 213 being used as the guiding structure, the first linear motor 340 and the second linear motor 350 can be kept moving along a straight line direction. From the perspective of the two slide rails 212 and the four sliders 213 being used as the supporting structure, the first linear motor 340 and the second linear motor 350 can be made to be balanced relative to the horizontal plane.

[0155] Further, on the basis of the aforementioned second preferred adjusting mechanism 300, refer to Figure 10 or Figure 12 or Figure 13 ., in the measuring mechanism 1 of this embodiment, the three movers of the first linear motor 340 are respectively a first mover 341, a second mover, and a third mover 343, and the second mover is located between the first mover 341 and the third mover 343;

[0156] The three movers of the second linear motor 350 are respectively a fourth mover 344, a fifth mover 345, and a sixth mover 346, and the fifth mover 345 is located between the fourth mover 344 and the sixth mover 346;

[0157] A first slide table 370 is provided on the second mover, and at least one edge probe 102 is provided on the slider of the first slide table 370;

[0158] A second slider 380 is provided on the fifth mover 345, and at least one edge probe 102 is provided on the slider of the second slider 380.

[0159] A second preferred adjustment mechanism 300 can be applied to the following scenarios;

[0160] Scenario A: The surface to be detected of the object to be measured is a flat surface. Thus, it is only necessary that the edge probes 102 on the three movers of the first linear motor 340 and the edge probes 102 on the third mover of the second linear motor 350 are respectively arranged in a straight line and contact the surface to be detected.

[0161] Scenario B: The surface to be detected of the object to be measured is a flat surface, but there is an obstacle in the middle of this plane. The obstacle is, for example, a protrusion or a recess on the plane. Thus, it is possible that the probe 100 on the second mover of the first linear motor 340 contacts the obstacle and does not contact the surface to be detected, or is suspended above the obstacle and does not contact the surface to be detected, and the probe 100 on the fifth mover 345 of the second linear motor 350 contacts the obstacle and does not contact the surface to be detected, or is suspended above the obstacle and does not contact the surface to be detected. At this time, by means of the first slider 370 provided on the second mover, the position of the edge probe 102 provided on the slider of the first slider 370 can be adjusted, so that the edge probe 102 can bypass the obstacle and contact the surface to be detected. Similarly, by means of the second slider 380 provided on the fifth mover 345, the position of the edge probe 102 provided on the slider of the second slider 380 can be adjusted, so that the edge probe 102 can bypass the obstacle and contact the surface to be detected.

[0162] It should be understood that the specific structure of the first slider 370, the specific structure of the second slider 380, and the specific structure of the third slider 390 in the following content can respectively adopt the structure of the slider in the prior art (see Figure 13 , the structure of the slider in the prior art is shown in the figure), which will not be elaborated here.

[0163] Furthermore, in the aforementioned second preferred adjustment mechanism 300, see Figure 10 or Figure 11 , the bracket 200 further includes a heightening plate member 214, and the heightening plate member 214 has a heightening portion 003 and a mounting portion 004;

[0164] The heightening portion 003 is connected to the support plate 211;

[0165] A third slider 390 is provided on the mounting portion 004, and the central axis probe 101 is provided on the slider of the third slider 390.

[0166] Among them, the elevation part 003 is connected to the support plate 211, so that a spacing is formed between the installation part 004 and the support plate 211, and the central axis probe 101 is arranged on the installation part 004; the installation part 004 is arranged between the first linear motor 340 and the second linear motor 350. Thus, the central axis probe 101 is arranged between the three movers of the first linear motor 340 and the three movers of the second linear motor 350.

[0167] In addition to increasing the spacing between the installation part 004 and the support plate 211, the elevation part 003 also has the function of spanning one of the slide rails 212. On this basis, a third slide table 390 is arranged on the installation part 004, and the central axis probe 101 is arranged on the sliding block of the third slide table 390, so that the central axis probe 101 can be adjusted to multiple positions through the third slide table 390.

[0168] It should be understood that in order to make the edge probe 102 as close as possible to the central area between the two linear motors, an edge adapter plate 302 can also be set;

[0169] Specifically, referring to Figure 9 , on the first linear motor 340, the edge adapter plate 302 connected to the first mover 341 is provided with an adapter part along the direction from the first linear motor 340 to the second linear motor 350 and along the direction from the first mover 341 to the third mover 343, and at least one edge probe 102 is arranged on this adapter part; the edge adapter plate 302 connected to the second mover is provided with an adapter part along the direction from the first linear motor 340 to the second linear motor 350 and along the direction from the second mover to the first mover 341 or along the direction from the second mover to the third mover 343, and at least one edge probe 102 is arranged on this adapter part; the edge adapter plate 302 connected to the third mover 343 is provided with an adapter part along the direction from the first linear motor 340 to the second linear motor 350 and along the direction from the third mover 343 to the first mover 341, and at least one edge probe 102 is arranged on this adapter part;

[0170] Further, on the second linear motor 350, the edge adapter plate 302 connected to the fourth mover 344 is provided with an adapter portion along the direction from the second linear motor 350 to the first linear motor 340 and along the direction from the fourth mover 344 to the sixth mover 346, and at least one edge probe 102 is disposed on the adapter portion; the edge adapter plate 302 connected to the fifth mover 345 is provided with an adapter portion along the direction from the second linear motor 350 to the first linear motor 340 and along the direction from the fifth mover 345 to the fourth mover 344 or along the direction from the fifth mover 345 to the sixth mover 346, and at least one edge probe 102 is disposed on the adapter portion; the edge adapter plate 302 connected to the sixth mover 346 is provided with an adapter portion along the direction from the second linear motor 350 to the first linear motor 340 and along the direction from the sixth mover 346 to the fourth mover 344, and at least one edge probe 102 is disposed on the adapter portion.

[0171] It should be understood that the shapes and structures of the above-mentioned multiple edge adapter plates 302 are not the same, and the shape and structure of any specific edge adapter plate 302 can be manufactured according to the actual distance between the first linear motor 340 and the second linear motor 350 and the specific shape of the object to be measured.

[0172] It should be understood that in addition to the edge adapter plates 302 being provided on the movers of the first linear motor 340 and the second linear motor 350, edge adapter plates 302 are also provided on the sliding blocks of the aforementioned third sliding table.

[0173] Embodiment 2:

[0174] In this embodiment, a measurement system is provided, which includes the measurement mechanism 1 in the aforementioned Embodiment 1, and also solves the technical problem in the prior art of how to change the positions of multiple sub-sensors relative to each other.

[0175] Specifically, referring to Figure 14 , in the measurement system of this embodiment, the number of measurement mechanisms 1 is multiple, and a positioning platform 2 is further included;

[0176] A detection area is provided on the positioning platform 2. Centered on the detection area, multiple measurement mechanisms 1 are radially located outside the detection area, and all the probes 100 of any one measurement mechanism 1 respectively point to the detection area;

[0177] In any two adjacent measurement mechanisms 1, any one probe 100 of the first measurement mechanism 1 and any one probe 100 of the second measurement mechanism 1 form an angle.

[0178] Among them, the positioning platform 2 is used to install the object to be measured, and the position that can accommodate the object to be measured is the detection area; according to the different shapes of the object to be measured, the measurement system of this embodiment can be configured into multiple schemes. The following lists several common schemes for the understanding of those skilled in the art.

[0179] Scheme 1. Refer to Figure 15 , the object to be measured has four detected surfaces. When the object to be measured is set on the positioning platform 2, the four detected surfaces are respectively perpendicular to the horizontal plane, and the four detected surfaces are respectively configured to be set along the positive X-axis, the positive Y-axis, the negative X-axis, and the negative Y-axis;

[0180] In Scheme 1, the measurement system of this embodiment is provided with four measurement mechanisms 1. The measurement mechanism 1 can actually be set as the first preferred measurement mechanism 1 or the second preferred measurement mechanism 1 in the foregoing Embodiment 1. During the actual measurement of the object to be measured, multiple probes 100 of the first measurement mechanism 1 are used to contact the detected surface set as the positive X-axis along the negative X-axis, multiple probes 100 of the second measurement mechanism 1 are used to contact the detected surface set as the positive Y-axis along the negative Y-axis, multiple probes 100 of the third measurement mechanism 1 are used to contact the detected surface set as the negative X-axis along the positive X-axis, and multiple probes 100 of the fourth measurement mechanism 1 are used to contact the detected surface set as the negative Y-axis along the positive Y-axis.

[0181] Scheme 2. Refer to Figure 15 , the object to be measured has five detected surfaces. When the object to be measured is set on the positioning platform 2, four of the detected surfaces are respectively perpendicular to the horizontal plane, and the four detected surfaces are respectively configured to be set along the positive X-axis, the positive Y-axis, the negative X-axis, and the negative Y-axis; the remaining one detected surface is parallel to the horizontal plane, so the following two setting methods are obtained;

[0182] The first setting method of Scheme 2. The remaining one detected surface is located at the upper part of the object to be measured in the vertical direction. In this setting method, the measurement system of this embodiment is provided with five measurement mechanisms 1. The measurement mechanism 1 can actually be set as the first preferred measurement mechanism 1 or the second preferred measurement mechanism 1 in the foregoing Embodiment 1. During the actual measurement of the object to be measured, the setting methods of the four measurement mechanisms 1 corresponding to the four detected surfaces perpendicular to the horizontal plane are the same as those of the four measurement mechanisms 1 corresponding to the four detected surfaces perpendicular to the horizontal plane in the foregoing Scheme 1, which will not be elaborated here; and the remaining one detected surface is actually configured to be set along the positive Z-axis. Thus, multiple probes 100 of the fifth measurement mechanism 1 are set to contact the detected surface set along the positive Z-axis along the negative Z-axis;

[0183] The second setting method of Solution 2, with the remaining one detected surface located at the upper part of the measured object in the vertical direction. Among them, the remaining one detected surface is actually configured to be set along the negative Z-axis. Thus, the multiple probes 100 of the fifth measuring mechanism 1 are set along the positive Z-axis to contact the detected surface set along the negative Z-axis. The setting methods of the remaining four measuring mechanisms 1 are the same as those of the four measuring mechanisms 1 in the aforementioned Solution 1 and will not be elaborated here.

[0184] Solution 3, refer to Figure 15 , the measured object has six detected surfaces. When the measured object is set on the positioning platform 2, four of the detected surfaces are respectively perpendicular to the horizontal plane and are respectively configured to be set along the positive X-axis, positive Y-axis, negative X-axis, and negative Y-axis; the remaining two detected surfaces are respectively parallel to the horizontal plane and are respectively configured to be set along the positive Z-axis and negative Z-axis;

[0185] In Solution 3, the measuring system of this embodiment is provided with six measuring mechanisms 1. During the actual measurement of the measured object, the setting methods of the four measuring mechanisms 1 corresponding to the four detected surfaces perpendicular to the horizontal plane are the same as those of the four measuring mechanisms 1 corresponding to the four detected surfaces perpendicular to the horizontal plane in the aforementioned Solution 1 and will not be elaborated here; the setting method of the measuring mechanism 1 corresponding to the detected surface configured to be along the positive Z-axis is the same as the setting method of the 'fifth measuring mechanism 1' in the first setting method of the aforementioned Solution 2 and will not be elaborated here; the setting method of the measuring mechanism 1 corresponding to the detected surface configured to be along the negative Z-axis is the same as the setting method of the 'fifth measuring mechanism 1' in the second setting method of the aforementioned Solution 2 and will not be elaborated here.

[0186] Regardless of whether Solution 1, Solution 2, or Solution 3 is adopted, the actual measurement processes of their corresponding specific measuring mechanisms 1 are the same or similar;

[0187] Specifically, before the multiple measuring mechanisms 1 actually detect the measured object, the measured object should be first set in the detected area of the positioning platform 2 to position the measured object relative to the positioning platform 2; after the measured object is positioned relative to the positioning platform 2, drive the multiple measuring mechanisms 1 to move towards the detected area simultaneously, so that all the probes 100 of any one measuring mechanism 1 respectively contact one of the detected surfaces; the measuring mechanism 1 that has completed the action of contacting the detected surface moves in the direction away from the detected area, and the work of the measuring mechanism 1 is completed.

[0188] It should be understood that the measuring mechanism 1 in the aforementioned Embodiment 1 does not have a driving device.

[0189] In this embodiment, refer to Figure 14 、Figures 16 to 18 , a set of driving components 3 are respectively arranged at any one of the measuring mechanisms 1;

[0190] The driving component 3 at least includes a first driving mechanism 31. The measuring mechanism 1 is connected to the first driving mechanism 31, and the first driving mechanism 31 is used to reciprocally drive the measuring mechanism 1 along the direction from the measuring mechanism 1 to the detection area.

[0191] Among them, the specific setting scheme of the driving component 3 should be set according to actual use requirements;

[0192] For example, referring to Figure 17 , if a certain measuring mechanism 1 is configured to contact the detected surface of the object to be measured in the positive X-axis direction, or a certain measuring mechanism 1 is configured to contact the detected surface of the object to be measured along the positive Z-axis direction, then, the driving component 3 should at least be provided with a first driving mechanism 31 such that the first driving mechanism 31 can drive the corresponding measuring mechanism 1 to approach or move away from the detection area, and then multiple probes 100 of the measuring mechanism 1 can contact the detected surface of the object to be measured, or the multiple probes 100 move away from the detected surface after the detection is completed;

[0193] Another example, referring to Figure 16 , if a certain measuring mechanism 1 is configured to contact the detected surface of the object to be measured in the positive X-axis direction and it is necessary to adjust the position of the measuring mechanism 1 relative to the object to be measured in the Y-axis direction, at this time, in addition to setting the aforementioned first driving mechanism 31, a second driving mechanism 32 should also be set. The second driving mechanism 32 is used to simultaneously drive the first driving mechanism 31 and the measuring mechanism 1 to reciprocate in the Y-axis direction, so as to realize adjusting the position of the measuring mechanism 1 relative to the object to be measured in the Y-axis direction.

[0194] The first driving mechanism 31 can be implemented by various structures in the prior art, including but not limited to linear motors or ball screw assemblies; the second driving mechanism 32 can be implemented by various structures in the prior art, including but not limited to linear motors or ball screw assemblies.

[0195] In the scheme where a certain measuring mechanism 1 is set to contact the detected surface of the object to be measured along the Z-axis direction, the first driving mechanism 31 actually becomes a lifting mechanism (refer to Figure 18 ), and the power source of the lifting mechanism includes but is not limited to having a lifting motor or a lifting cylinder;

[0196] When the power source is a lifting motor, structures such as a speed reducer, a coupling, a threaded rod, a lifting plate, a lifting guide rod, and a lifting slider should be matched. The above structures are well-known common knowledge to those skilled in the art and will not be elaborated here;

[0197] When the power source is a lifting cylinder, structures such as a lifting positioning plate, a sliding rod, and a slider should be matched. The above structures are common knowledge known to those skilled in the art and will not be elaborated here.

[0198] In actual settings, if a certain measuring mechanism 1 is set to measure the detected surface of the object to be measured in the horizontal direction, then the measuring mechanism 1 should be connected to the moving part of the first driving mechanism 31. The moving part is, for example, the mover of a linear motor or the ball of a ball screw assembly. At the same time, the first driving mechanism 31 should be connected to the moving part of the second driving mechanism 32. The moving part is, for example, the mover of a linear motor or the ball of a ball screw assembly.

[0199] If a certain measuring mechanism 1 is set to measure the detected surface of the object to be measured in the vertical direction, then the measuring mechanism 1 should be connected to the lifting plate or positioning plate of the first driving mechanism 31.

[0200] Furthermore, as previously mentioned, the object to be measured is set within the detection area and is positioned relative to the positioning platform 2. Then, how to position the object to be measured relative to the positioning platform 2 becomes a new technical problem.

[0201] In this embodiment, referring to Figure 19 and Figure 20 , the measuring system further includes a backing plate 4 and a cylinder 5.

[0202] The backing plate 4 and the cylinder 5 are respectively arranged on the positioning platform 2.

[0203] The backing plate 4 is provided with a first clamping body 41, and the piston part of the cylinder 5 is provided with a second clamping body 51. The detection area is located between the first clamping body 41 and the second clamping body 51.

[0204] In actual use, the backing plate 4 and the cylinder 5 are respectively detachably connected to the positioning platform 2. Thus, the second clamping body 51 forms a position relative to the positioning platform 2 through the cylinder body part of the cylinder 5, and the first clamping body 41 forms a position relative to the positioning platform 2 through the backing plate 4. When the object to be measured is set in the detection area, it is clamped by the second clamping body 51 arranged on the piston part of the cylinder 5 and the first clamping body 41 on the backing plate 4, so that the object to be measured is positioned relative to the positioning platform 2.

[0205] Furthermore, as previously mentioned, if a certain measuring mechanism 1 is arranged below the detection area in the vertical direction (the measuring mechanism 1 arranged in the negative Z-axis direction), then the probe 100 of the measuring mechanism 1 located below the detection area and the detection area will be blocked by the aforementioned positioning platform 2 and backing plate 4, resulting in the inability of the probe 100 of the measuring mechanism 1 to contact the object to be measured arranged in the detection area.

[0206] To solve the above problem, referring toFigure 19 and Figure 20 In this embodiment of the measurement system, the backing plate 4 is provided with a plurality of first detection through holes 42. Any one of the first detection through holes 42 penetrates through the backing plate 4 respectively, and the center line of any one of the first detection through holes 42 points to the detection area respectively;

[0207] The positioning platform 2 is also provided with a plurality of second detection through holes 21. The number of the second detection through holes 21 is the same as that of the first detection through holes 42. Any one of the second detection through holes 21 and one of the first detection through holes 42 are configured to be coaxially and identically-diameter communicated. Among them, one of the second detection through holes 21 and one of the first detection through holes 42 in the same state are respectively used to be penetrated by one of the probes 100 of the measurement mechanism 1 located below the detection area.

[0208] In actual setting, the backing plate 4 and the positioning platform 2 are configured to be detachably connected. Thus, when the specific structure of the object to be measured is changed (for example, in the case of changing the size and / or changing the structure of the detected surface), then the fixing of the new object to be measured can be realized by replacing the backing plate 4 with a model-matching one;

[0209] After the backing plate 4 is set on the positioning platform 2, any one of the first detection through holes 42 on the backing plate 4 communicates with one of the second detection through holes 21 of the positioning platform 2 respectively. Since their diameters are the same and their axis lines are collinear, thus, after one of the probes 100 penetrates through the second detection through hole 21, it will not encounter obstacles from the first detection through hole 42;

[0210] It should be understood that any one of the first detection through holes 42 and any one of the second detection through holes 21 should respectively form a clearance fit with the corresponding probe 100, so as to reduce or avoid the friction between the probe 100 and the backing plate 4 and improve the reliability.

[0211] It should be understood that the connection between the cylinder 5 and the positioning platform 2 and the connection between the backing plate 4 and the positioning platform 2 described above can be respectively realized by connection structures in the prior art, including but not limited to: bolt connection, dowel pin connection and other connection structures.

[0212] It should be understood that the specific structures of the aforementioned first clamping body 41 and second clamping body 51 can be realized by various structures in the prior art, including but not limited to: clamping blocks, clamping plates, clamping claws and other structures.

[0213] It should be understood that, based on all the foregoing solutions, the measurement system of this embodiment is further provided with a controller. The motors of all the measurement mechanisms 1, the motors of the foregoing driving mechanisms, the foregoing cylinder 5, and all the probes 100 are electrically connected to the controller respectively. Thus, the controller can issue control instructions and control the start / stop, forward / reverse rotation of the corresponding motors according to the control instructions, or control the expansion / contraction of the cylinder 5 according to the control instructions. The feedback electrical signals of the probes 100 can be transmitted to the controller, enabling the controller to perform calculations based on the feedback electrical signals of the probes 100.

[0214] Further, in all the foregoing solutions, the position of the cylinder 5 and the position of the backing plate 4 are arranged on different mounting surfaces relative to the positioning platform 2 to avoid the position of the cylinder 5 affecting the detection of the object to be measured by one of the measurement mechanisms 1.

[0215] Specifically, referring to Figure 19 and Figure 20 , the positioning platform 2 is provided with a mounting plate 22, and the foregoing second detection through holes 21 penetrate through the mounting plate 22 respectively. Along the vertical direction, the mounting plate 22 has a top surface at the upper part and a bottom surface at the lower part. The backing plate 4 is arranged on the top surface, while the cylinder 5 is arranged on the bottom surface.

[0216] In the above setting, the first clamping body 41 on the backing plate 4 and the second clamping body 51 on the cylinder 5 are isolated by the mounting plate 22. Therefore, to solve this problem, the following technical solution is provided in this embodiment;

[0217] A travel slot 23 is provided on the mounting plate 22. The travel slot 23 penetrates through the mounting plate 22, and a distance is formed between the contour of the travel slot 23 and the contour of any one of the foregoing second detection through holes 21. The second clamping body 51 is configured to penetrate through the travel slot 23 along the direction from the bottom surface to the top surface of the mounting plate 22, and the path formed by the second clamping body 51 along the piston movement direction of the cylinder 5 is restricted within the travel slot 23. Among them, the second clamping body 51 exposed at the top surface and the foregoing first clamping body 41 are used to clamp the object to be measured.

[0218] The foregoing are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
