The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

Further, although the terms used in the present application are selected from publicly known and used terms, some of the terms mentioned in the specification of the present application may be selected by the applicant at his or her discretion, the detailed meanings of which are described in relevant parts of the description herein.

Further, it is required that the present application is understood not only by the actual terms used but also by the meaning of each term lying within.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

The embodiment of the application provides a supplementary tool of probe unit mount. Referring to fig. 1 to 7, an auxiliary fixture 100 for mounting a probe assembly according to an embodiment of the present disclosure may include: a holder 110 and an anti-rotation structure 120. The holder 110 may be used to hold the stylus assembly 200 and the anti-rotation structure 120 may be used to prevent the dock 220 of the stylus assembly 200 held by the holder 110 from rotating relative to the holder 110.

In this way, in the embodiment of the present application, when the posture of the stylus assembly 200 is adjusted, the coordinate measuring machine base may be connected to the docking connector 220 of the stylus assembly 200, and then the stylus assembly 200 may be placed on the stylus holder to adjust the stylus assembly 200 placed on the stylus holder to a proper angle.

Further, the stylus member mounting auxiliary jig 100 may be disposed at a target position on the coordinate measuring machine. In the case where the stylus assembly mounting auxiliary jig 100 is located at the target position, the stylus assembly 200 may be held by the holder 110. In addition, the pin assembly 200 can be prevented from rotating relative to the holder 110 by the anti-rotation structure 120.

After the stylus assembly 200 is fastened to the stylus assembly mounting auxiliary jig 100 by using the holder 110 and the rotation preventing structure 120, the stylus assembly mounting auxiliary jig 100 together with the stylus assembly 200 may be moved to a position that does not affect the operation of the coordinate measuring machine, and the posture of the stylus assembly 200 may be adjusted at the position that does not affect the operation of the coordinate measuring machine.

After the stylus assembly 200 is adjusted to a proper posture, the stylus assembly 200 may be set to a base of the coordinate measuring machine, and the stylus assembly 200 set to the base may be put back to the stylus holder by the coordinate measuring machine. In other embodiments of the present application, the stylus assembly 200 may also be placed directly back into the stylus holder.

Furthermore, in the embodiment of the present application, for example, in the process of placing the stylus assembly 200 on the base of the coordinate measuring machine and placing the stylus assembly 200 placed on the base back into the stylus holder by the coordinate measuring machine, the stylus assembly 200 may be manually placed on the base of the coordinate measuring machine, the stylus assembly 200 placed on the base of the coordinate measuring machine may be calibrated, after the calibration of the stylus assembly 200 is completed, the coordinate measuring machine may be operated to define the position of the stylus assembly 200 on the stylus holder, and then the coordinate measuring machine may place the stylus assembly 200 back into the corresponding position on the stylus holder.

Further, when measurement using the stylus assembly 200 is required, the coordinate measuring machine may be connected to the docking connector 220 of the stylus assembly 200 adjusted to a target posture.

Therefore, by adopting the scheme provided by the embodiment of the application, the posture of the measuring pin assembly 200 can be adjusted at the position without influencing the work of the coordinate measuring instrument, and the measuring seat is not occupied in the process of adjusting the posture of the measuring pin assembly 200, so that the work efficiency of the coordinate measuring instrument can be improved.

Referring to fig. 2-4, in an embodiment of the present application, the gripper 110 may include a first jaw 111 and a second jaw 112. The gripper 110 may have a gripping state and an unclamping state. During the switching of the gripper 110 from the release state to the gripping state, the first jaw 111 and the second jaw 112 approach each other. Thus, the stylus assembly 200 may be held by the first jaw 111 and the second jaw 112 by bringing the first jaw 111 and the second jaw 112 close to each other. During the switching of the gripper 110 from the gripping state to the release state, the first jaw 111 and the second jaw 112 are moved away from each other. Thus, the stylus assembly 200 of the gripper 110 can be placed to a predetermined position by moving the first jaw 111 and the second jaw 112 away from each other.

In the embodiment of the present application, the holder 110 may also be a holder made based on other principles, and for example, the holder 110 may have an electromagnetic member, and a magnetic attraction force may be generated by using the electromagnetic member of the holder 110, so that the holder 110 may be connected to the stylus assembly 200.

It should be noted that the holder 110 provided in the embodiment of the present application may also be any holder capable of being connected to the stylus assembly 200 in the prior art, and the specific configuration of the holder 110 in the embodiment of the present application will not be described.

In order to enable those skilled in the art to better understand how the anti-rotation structure 120 constrains the stylus assembly 200 to prevent rotation of the stylus assembly 200 relative to the holder 110, it is necessary to first briefly describe the specific construction of the stylus assembly 200.

Referring to fig. 5 to 6, in an embodiment of the present application, the stylus assembly 200 may include a stylus 210 and a dockee 220, and a side of the dockee 220 facing away from the stylus 210 may be provided with a first docking structure 221. Generally speaking, the end of the stylus of the coordinate measuring machine may be provided with a second docking structure, which may be in locating engagement with the first docking structure 221, so that the stylus assembly 200 may generally only be connected to a stylus of a coordinate measuring machine base in a particular attitude. In this way, the stylus assembly 200 is prevented from rotating relative to the stylus. In addition, in general, the probe and the dockee 220 are generally provided with a magnetic attraction member, so that the probe and the dockee 220 may be connected by a magnetic attraction force generated by the magnetic attraction member.

Referring to fig. 2 to 4, and fig. 7, in an embodiment of the present application, the anti-rotation structure 120 may include a connector 121 and a locker 122. The connector 121 may be used to connect with the docking unit 220 of the stylus assembly 200, and the locker 122 may be used to lock the connector 121 in the case where the connector 121 is connected with the docking unit 220. In this way, the coupling member 121 can be coupled to the docking member 220 of the stylus assembly 200, and the stylus assembly 200 can be indirectly locked by locking the coupling member 121 using the locker 122, so that the stylus assembly 200 can be prevented from rotating with respect to the holder 110.

It should be noted that, in the embodiment of the present application, the stylus assembly 200 may include a stylus 210 and a dockee 220, and a side of the dockee 220 facing away from the stylus 210 may be provided with a first docking structure 221. Referring to fig. 7, the connecting member 121 may be provided with a third docking structure 1211, and the third docking structure 1211 may be positioned and matched with the first docking structure 221. In this way, the pin assembly 200 can be prevented from rotating relative to the connector 121 by the positioning and matching relationship between the third docking structure 1211 and the first docking structure 221.

Further, in an embodiment of the present application, in a case where the rotation preventing structure 120 includes the connector 121, the connector 121 may be used to connect with the dockee 220 by a magnetic attraction force. For example, the docking unit 220 and the connection unit 121 may be respectively provided with magnetic attraction members, so that the connection unit 121 and the docking unit 220 may be connected by a magnetic attraction force generated between the magnetic attraction members. In this way, a connection between the stylus assembly 200 and the connector 121 may be achieved. Further, the docking unit 220 of the stylus assembly 200 may be indirectly locked by locking the coupling member 121 using the locker 122, so that the docking unit 220 of the stylus assembly 200 may be prevented from rotating with respect to the holder 110.

In the embodiment of the present application, the connecting member 121 may have a structure similar to a probe of a coordinate measuring machine base, and in the embodiment of the present application, the connecting member 121 may be referred to as a profiling probe. The connecting structure of the probe head for copying and connecting with the probe assembly 200 has the same dimension and specification as the connecting structure of the probe head of the measuring base of the coordinate measuring machine and connecting with the probe assembly 200. Thus, the stylus assembly 200 can be connected by the stylus. Further, the stylus unit 200 may be indirectly locked by the locker 122 by locking the copying probe.

It should also be noted that in other embodiments of the present application, other means may be used to prevent the dock 220 of the stylus assembly 200 from rotating relative to the holder 110. For example, in the case where the clamper 110 includes the first jaw 111 and the second jaw 112, a friction force increasing structure may be provided between opposite sides of the first jaw 111 and the second jaw 112, so that the stylus assembly 200 may be prevented from rotating relative to the clamper 110 by raising a friction force of the clamper 110 with a clamping portion of the stylus assembly 200.

Illustratively, two opposite sides of the first jaw 111 and the second jaw 112 of the gripper 110 may be respectively provided with vertical stripes, and the vertical stripes arranged on the first jaw 111 and the second jaw 112 may be used as anti-rotation structures. In this way, the friction between the holder 110 and the holding portion of the stylus assembly 200 can be increased by the vertical stripes provided on the first jaw 111 and the second jaw 112, respectively, so that the stylus assembly 200 can be prevented from rotating relative to the holder 110.

It should be noted that, in the embodiment of the present application, the holder 110 may hold the stylus 210, and the holder 110 may also hold the docking unit 220. For example, in the case that the holder 110 holds the stylus 210, the holding portion of the stylus 210 may be provided with a knurled structure, so that the friction between the holder 110 and the stylus assembly 200 may be increased by the provided knurled structure, and thus the stylus assembly 200 may be prevented from rotating relative to the holder 110. It is understood that the embodiments of the present application can also prevent the rotation of the stylus assembly 200 relative to the holder 110 in various ways known in the art, and other solutions for preventing the rotation of the stylus assembly 200 relative to the holder 110 will not be described herein.

Referring to fig. 2 to 4, and fig. 7, in an embodiment of the present application, the stylus assembly mounting auxiliary fixture 100 may further include a base 140. In the case where the anti-rotation structure 120 includes the connector 121 and the locker 122, the anti-rotation structure 120 may further include a rotation shaft 123. The rotating shaft 123 is rotatably disposed on the base 140, and the rotating shaft 123 is slidable along an axial direction of the rotating shaft 123. The connecting member 121 may be fixedly disposed on the rotating shaft 123. The locker 122 may be used to lock the rotating shaft 123 in a state that the connector 121 is coupled with the docking connector 220. In this way, the connector 121 can be better connected with the docking connector 220 of the stylus assembly 200 by rotating the connector 121.

In the embodiment of the present application, the rotating shaft 123 may be provided with a control handle 124, and in a case that the control handle 124 is controlled, the control handle 124 can drive the rotating shaft 123 to rotate or slide. Thus, the rotating shaft 123 can be driven to rotate or slide by manipulating the handle 124, so that the connecting member 121 can be indirectly driven to rotate or slide.

In the embodiment of the present application, in the case that the docking unit 220 of the stylus assembly 200 is provided with the first docking structure 221, and the connecting element 121 is provided with the third docking structure 1211 (or the connecting element 121 is a profiling measuring head), the handle 124 may be manipulated to rotate, so as to drive the connecting element 121 to rotate, and the third docking structure 1211 of the connecting element 121 may be opposite to the first docking structure 221 of the docking unit 220 by rotating the connecting element 121. Therefore, the handle 124 can be operated to drive the rotating shaft 123 to slide towards the direction close to the butt-joint unit 220, so that the connecting member 121 and the butt-joint unit 220 of the stylus assembly 200 can be close to each other until the two are connected. Further, the coupling member 121 may be locked by the locker 122.

It should be noted that although in the foregoing description, only the coupling member 121 has been described as being magnetically coupled to the docking member 220, it should be understood that as the technology advances, the stylus of the coordinate measuring apparatus may be coupled in other ways than the magnetic coupling of the prior art. In the case of the coupling element 121 being a feeler, the coupling element 121 and the docking adapter 220 can be coupled in other ways that will occur in the future. The embodiment of the present application does not limit the specific connection form of the connection member 121 and the docking unit 220.

Although the locking device 122 may adopt a locking structure in the prior art, in order to enable those skilled in the art to better connect with the solution of the embodiment of the present application, the embodiment of the present application provides a more specific configuration of the locking device for those skilled in the art to refer to.

Referring to fig. 2 to 4, in an embodiment of the present application, the locker 122 may include an abutment 1221 and a fastening handle 1222. The abutment 1221 may be threadedly connected to the base 140, the abutment 1221 may be provided with an abutment 12211, and the fastening handle 1222 may be drivingly connected to the abutment 1221. In the case of the fastening handle 1222 being manipulated, the fastening handle 1222 can bring the abutment 1221 to rotate; during the rotation of the abutting piece 1221 relative to the base 140, the abutting portion 12211 can move toward or away from the rotation shaft 123 to lock or release the rotation shaft 123. In this way, the fastening of the connecting member 121 can be conveniently achieved by rotating the fastening handle 1222 and locking the rotation shaft 123 by the abutment member 1221 screwed to the base 140.

It should be noted that, in the embodiment of the present application, the holder 110 may be connected with the rotation preventing structure 120. The holder 110 can be disposed on the base 140 and the anti-rotation structure 120 can also be disposed on the base 140, such that the base 140 can be utilized to achieve an indirect connection between the holder 110 and the anti-rotation structure 120. It should be noted that, in other embodiments of the present application, the holder 110 and the anti-rotation structure 120 may be connected in other ways, and it is only necessary that the anti-rotation structure 120 can prevent the abutment 220 of the stylus assembly 200 held by the holder 110 from rotating relative to the holder 110.

Referring to fig. 6 to 7, in an embodiment of the present application, the stylus assembly mounting auxiliary fixture 100 is further provided with a third positioning portion 150, and the third positioning portion 150 may be used to position an adjusting portion 211 of a stylus 210 that the stylus assembly 200 may include, so as to adjust the adjusting portion 211 to a target posture. In this way, the adjustment portion 211 can be adjusted to the target posture by the third positioning portion 150 of the stylus component mounting auxiliary fixture 100, and the difficulty of adjusting the adjustment portion 211 to the target posture can be reduced, so that the adjustment portion 211 can be conveniently adjusted to the target posture by the operator.

Referring to fig. 6, exemplarily, in an embodiment of the present application, the stylus 210 of the stylus assembly 200 may be a five-direction stylus. The stylus 210 may include a main body portion 212 and an adjusting portion 211. The main body part 212 may be used to connect with the dockee 220, and the adjusting part 211 may be connected with the main body part 212.

In an embodiment of the present application, in the case where the stylus 210 is a five-direction stylus, the body portion 212 may include a first connecting rod 2121, a second connecting rod 2122, and a first sub-stylus 2123. The adjusting part 211 may include a second sub-stylus 2111, a third sub-stylus, a fourth sub-stylus, a fifth sub-stylus, and a connection seat 2112. The second sub-probe 2111, the third sub-probe, the fourth sub-probe and the fifth sub-probe may be respectively connected to the connection seat 2112.

The first and second connecting rods 2121 and 2122 may be threadedly connected, and the connecting seat 2112 may be inserted between the first and second connecting rods 2121 and 2122, and the connecting seat 2112 may be fastened between the first and second connecting rods 2121 and 2122 when the first and second connecting rods 2121 and 2122 are in a fastened state. When the first and second connecting rods 2121 and 2122 are in a relaxed state, the connecting seat 2112 can rotate relative to the first connecting rod 2121. In an embodiment of the present application, the first connecting rod 2121 may be threadedly connected with the dockee 220.

Note that, in the case where the holder 110 holds the stylus 210, the holder 110 may hold the first connecting rod 2121. In this way, since the first connecting rod 2121 and the docking unit 220 are fixedly connected by means of the screw connection therebetween, the holder 110 and the docking unit 220 can be indirectly connected by means of the first connecting rod 2121 held by the holder 110. Furthermore, the connecting seat 2112 can rotate relative to the first connecting rod 2121 by unscrewing the second connecting rod 2122, so that the posture of the connecting seat 2112 can be adjusted, and the postures of the second sub-probe 2111, the third sub-probe, the fourth sub-probe and the fifth sub-probe can be adjusted.

It should be noted that, in the embodiment of the present application, the stylus 210 may not be a five-direction stylus, for example, a fifth sub-stylus of the stylus 210 may be taken out, so that the stylus 210 is a four-direction stylus. Further, the stylus 210 may also be, for example, an L-shaped stylus or other shaped stylus. And will not be described further herein.

Referring to fig. 2, 8 and 9, in order to enable the stylus assembly mounting auxiliary jig 100 to be located at a target position during the process of taking out the stylus assembly 200 from the stylus holder 300, in an embodiment of the present application, the stylus assembly mounting auxiliary jig 100 may be provided with the first positioning portion 130.
