The probe is required to be accurately adjusted before the three-coordinate measuring instrument is used for measuring, and the accuracy of the angle of the probe is one of the influence factors of the measuring error of the three-coordinate measuring instrument, so that the requirement on the angle of the probe is very strict. However, in the existing three-coordinate measuring system, the angle of the probe is often adjusted and positioned by using a projection or other methods, and a positioning adjusting device for the angle of the probe is lacking at present.
In view of this, the present invention provides a three-coordinate measuring system, which includes a positioning adjustment device, where the positioning adjustment device is used to adjust the probe angle on the measuring head device, and any three-coordinate measuring system including the positioning adjustment device is included in the three-coordinate measuring system of the present invention.

Referring to fig. 1 to 4, the present invention further provides a positioning adjustment apparatus 100 for adjusting the orientation of a probe 230 in a probe device, the probe device includes a probe head body, a connecting portion 220 rotatably mounted on the probe head body around a longitudinally extending axis, and the probe 230 rotatably mounted on the connecting portion 220 along a transversely extending axis, the positioning adjustment apparatus 100 includes: the device comprises a base 1, a mounting component 2, a first positioning component 3 and a second positioning component 4. The mounting assembly 2 includes a first mounting seat 21 and a second mounting seat 22 which are arranged on the base 1, the first mounting seat 21 is used for mounting the probe main body, the second mounting seat 22 is arranged on the base 1 around the first mounting seat 21, one of the first mounting seat 21 and the second mounting seat 22 is fixedly mounted on the base 1, and the other one is rotatably mounted on the base 1 around a longitudinal axis, so that the first mounting seat 21 and the second mounting seat 22 can rotate relatively; the first positioning assembly 3 includes a positioning member 31 disposed adjacent to the probe 230 on the second mounting seat 22 and a connecting member 32 disposed on the positioning member 31, the positioning member 31 is provided with a plurality of first scales 311, the plurality of first scales 311 are disposed at intervals along a rotation direction of the probe 230 to mark a rotation angle of the probe 230, and the connecting member 32 is connected to the connecting portion 220, so that when the first mounting seat 21 and the second mounting seat 22 rotate relatively, the connecting portion 220 and the probe head main body rotate relatively in synchronization; the second positioning assembly 4 includes an identification pointer 41 and a second scale 42 corresponding to each other, one of the identification pointer 41 and the second scale 42 is disposed on the first mounting seat 21, and the other is disposed on the second mounting seat 22, so as to identify a relative rotation angle between the first mounting seat 21 and the second mounting seat 22.
The longitudinal direction and the transverse direction are opposite directions, the longitudinal direction and the transverse direction are two orthogonal directions, and the others are not limited.
In the technical solution of the present invention, the first mounting seat 21 and the second mounting seat 22 are relatively rotatable, the second mounting seat 22 is connected to the connecting portion 220 through the connecting member 32, and the probe head body is mounted on the first mounting seat 21, so that when the first mounting seat 21 and the second mounting seat 22 rotate relatively, the probe head body and the connecting portion 220 rotate relatively at the same angle. Therefore, the relative rotation angle between the first mounting seat 21 and the second mounting seat 22, that is, the relative rotation angle between the probing tip main body and the connecting portion 220, can be identified by the identification pointer 41 and the second scale 42 in the second positioning assembly 4, so as to precisely adjust the angle between the probing tip main body and the connecting portion 220. The probe 230 is rotatably mounted on the connecting portion 220, so that the rotation angle of the probe 230 relative to the connecting portion 220 can be clearly and accurately marked through the first scale 311 on the positioning member 31.
The positioning adjustment device 100 according to the present invention identifies the rotation angle of the probe 230 with respect to the connecting portion 220 and the rotation angle of the connecting portion 220 with respect to the probe head body, so as to define the angle of the probe 230 with respect to the three-coordinate measuring apparatus body, which enables a user to accurately adjust the probe 230 to a desired angle, and has the advantages of simple operation and high adjustment precision.
When in use, the probe 230, the connecting portion 220 and the probe head body need to be disconnected to at least allow the probe 230, the connecting portion 220 and the probe head body to rotate relative to each other, and after the angle adjustment is completed, the probe 230, the connecting portion 220 and the probe head body are connected to each other. It should be noted that there is no sequence between the adjustment of the angle of the probe 230 and the adjustment of the angle of the connecting portion 220, and the adjustment can be selected according to the use requirement.
Further, referring to fig. 1 to 3, the positioning element 31 of the first positioning element 3 needs to be close to the probe 230 to accurately mark the angle of the probe 230 relative to the connecting portion 220. However, there may be differences between different gauge head arrangements, which makes it impossible for the positioning element 31 to accurately identify the angle of the probe 230 on each gauge head arrangement when the positioning element is fixedly mounted. Therefore, in an embodiment of the present invention, the first positioning assembly 3 further includes a mounting structure 33, one end of the mounting structure 33 in the longitudinal direction is mounted on the second mounting seat 22, the other end is used for mounting the positioning element 31, and the mounting structure 33 is telescopically arranged on the second mounting seat 22 in the longitudinal direction.
In this embodiment, the mounting structure 33 is disposed on the second mounting seat 22 in a longitudinally telescopic manner, so that the positioning element 31 can be adjusted in position along the longitudinal direction, thereby adapting to a variety of measuring head devices and meeting more use requirements.
Further, the mounting structure 33 includes: a sleeve 331 and a movable block 332. The sleeve 331 extends longitudinally to the second mounting seat 22; the movable block 332 is movably installed in the sleeve 331 along the longitudinal direction, and one end of the movable block 332 close to the positioning member 31 is connected to the positioning member 31.
In this embodiment, after the measuring head device is installed, a user can directly connect the connecting part 32 with the connecting part 220, and in this process, the positioning part 31 can be adjusted in position and is driven to a proper position by the connecting part 32. Specifically, the movable block 332 moves in the sleeve 331 so as to adjust the position of the positioning member 31 in the longitudinal direction, and the connecting member 32 is connected to the connecting portion 220, which also enables the positioning member 31 to be fixed at a proper measuring position.
Specifically, the first mounting seat 21 is fixedly mounted on the base 1, and the second mounting seat 22 is rotatably mounted on the base 1 around an axis in the longitudinal direction.
In this embodiment, the second installation seat 22 is disposed outside the first installation seat 21, the first installation seat 21 is fixedly disposed, and the second installation seat 22 is rotatably disposed, so that the adjustment can be performed only by rotating the second installation seat 22 outside, which is more convenient. Of course, the first mounting seat 21 may be configured to rotate, and the second mounting seat 22 is configured to be fixed, so that it is slightly inconvenient to rotate the first mounting seat 21 located at the inner side.
Further, the first mounting seat 21 is a cylindrical device, and the second mounting seat 22 is an annular boss matched with the first mounting seat 21; the identification pointer 41 is disposed on a side of the second mounting seat 22 close to the first mounting seat 21, the second scale 42 includes a plurality of scale lines 42a disposed on a side wall of the first mounting seat 21 opposite to the identification pointer 41, and the plurality of scale lines 42a are disposed at intervals along a circumferential direction of the second mounting seat 22.
In this embodiment, the plurality of graduation lines 42a in the second graduation 42 need to be arranged at intervals along an arc, and when the first installation seat 21 is formed in a cylindrical shape, the side wall of the first installation seat 21 is very suitable for arranging the plurality of graduation lines 42 a. Moreover, the first mounting seat 21 is configured as the cylinder, and the second mounting seat 22 can be correspondingly configured as an annular boss, so that the first mounting seat 21 and the second mounting seat 22 are more compact and occupy less space. Of course, the first mounting seat 21 and the second mounting seat 22 may also have other shapes, as long as the relative rotation between the first mounting seat 21 and the second mounting seat 22 is not affected, and the specific limitation is not made.
Further, the positioning adjustment apparatus 100 further includes a fixing member adjustably disposed on the second mounting seat 22, so that the fixing member has a working state of relatively fixing the first mounting seat 21 and the second mounting seat 22 during the adjustment process.
In this embodiment, after the first mounting seat 21 and the second mounting seat 22 complete the relative rotation, the angle between the connecting portion 220 and the probing tip main body is also adjusted, and at this time, the connection between the connecting portion 220 and the probing tip main body needs to be fastened, which may cause the first mounting seat 21 and the second mounting seat 22 to find the deviation during the operation, thereby affecting the adjustment accuracy. The fixing member can be adjusted to the working state again, and the first mounting seat 21 and the second mounting seat 22 are relatively fixed, so that the accuracy of the angle between the connecting portion 220 and the probe head body is ensured.
Specifically, the second mounting seat 22 is provided with a threaded through hole 221 extending from the second mounting seat 22 to the first mounting seat 21, the fixing member is a screwed member screwed with the threaded through hole 221, and the screwed member is used for extending from the threaded through hole 221 in the working state to abut against the first mounting seat 21.
In this embodiment, when the screw member extends into the through hole 221 and is screwed with the through hole 221, the screw member can move in the through hole 221 by changing the screwing position with the through hole 221. When the screw extends out from the other end of the threaded through hole 221, the screw abuts against the first mounting seat 21, and the relative movement between the first mounting seat 21 and the second mounting seat 22 is limited by abutting against the first mounting seat 21.
It is noted that the fixing element has other embodiments. For example, when the second mounting seat 22 is movable, the second mounting seat 22 can be fixedly mounted by connecting the second mounting seat 22 with the base 1, so that the relative movement between the first mounting seat 21 and the second mounting seat 22 can also be limited.
Furthermore, the screw connector is a ball head jackscrew; the periphery of the first installation seat 21 is provided with a plurality of abutting holes corresponding to the ball head jackscrew at intervals, so that the ball head jackscrew and the first installation seat 21 extend into the abutting holes when abutting against each other.
The screw is abutted to limit the relative movement between the first mounting seat 21 and the second mounting seat 22, which may cause loss of the second mounting seat 22. In this embodiment, when the ball-head jackscrew abuts against the second mounting seat 22, the ball head of the ball-head jackscrew extends into the abutting hole, so that relative movement between the first mounting seat 21 and the second mounting seat 22 can be limited by matching the abutting hole with the ball-head jackscrew without being particularly compact, and consumption of the second mounting seat 22 is greatly reduced.
Further, the connecting member 32 is provided with a clamping jaw 321 at an end close to the connecting portion 220 to clamp the connecting portion 220. In a specific application, the connecting member 32 is connected to the connecting portion 220 through the clamping jaws 321, and after the positioning adjustment is completed, the connecting member 32 and the connecting portion 220 can be released by loosening the clamping jaws 321.
In fact, the connecting member 32 can be rotatably installed on the positioning member 31, and the specific rotating direction is consistent with the rotating direction of the probe 230, at this time, the connecting member 32 can be connected with the probe 230, and when the probe 230 rotates, the connecting member 32 is driven to rotate together, so that the installation mode of the positioning member 31 is more free.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
