Technical Field

[0001] The present invention relates to the technical field of vibration detection, in particular to a vibration testing device for a quartz claw. Background Art

[0002] For example, publication number "CN119984101A" discloses "a quartz claw detection device," in which the quartz claw includes: a shaft and a plurality of supporting claws arranged on the shaft; wherein the detection device includes: a workbench; a concentric shaft clamping assembly, arranged on the workbench, for clamping the vertically arranged shaft; a disk, arranged on the upper end surface of the supporting claw; and a runout detection assembly; wherein the shaft can rotate on the concentric shaft clamping assembly, so that the runout detection assembly can detect the runout value of the upper end surface and the runout value of the side of the disk. However, in actual applications, when using this type of equipment, due to the presence of an angled detection section and a wide structure at the end of the quartz claw, if the quartz claw is directly installed, the quartz claw may interfere with and hit the detection equipment, affecting the detection accuracy and safety of use. Summary of the Invention

[0003] In response to the problem in the prior art mentioned in the background technology that the quartz claws may interfere with and collide with the detection equipment, the present invention provides a quartz claw vibration testing device that can be installed in an offset manner by rotation, so that the end of the quartz claw can avoid the detection equipment and reduce the risk of interference and collision.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions.

[0005] A quartz claw vibration testing device includes a support frame and a turntable seat, the turntable seat is connected to a rotating drive member, the support frame is provided with an angle detection section, the angle detection section is provided with a vibration detection unit, the turntable seat is rotatably connected to an adjustment seat, the adjustment seat is connected to a measured claw unit, the measured claw unit is detachably connected to the adjustment seat, and the measured claw unit can rotate relative to the support frame. During the detection process of the quartz claw, since it is necessary to use the light detection of the jump detection unit, the jump detection component will produce an overlapping area with the claw unit to be measured in the vertical direction. Since the jump detection unit is connected to the angle detection section, there is an angle structure at the angle detection end, and there will be a section of structure extending close to the claw unit to be measured. Therefore, during the installation of the claw unit to be measured, it is necessary to stagger the claw part of the claw unit to be measured and the jump detection unit as much as possible, and at the same time, the bottom of the claw unit to be measured needs to be aligned and connected with the turntable seat. This process needs to take into account the positions of both ends at the same time. If there is negligence, the claw unit to be measured and the jump detection unit will collide and interfere, affecting the positioning accuracy and product safety. Therefore, in response to the above-mentioned problem, in the present application, an adjusting seat is provided on the turntable seat, and the adjusting seat can rotate on the turntable seat, and a hole or a limiting device that can be connected to the measured claw unit is provided on the adjusting seat, such as a clamping claw, a caliper, a collet structure, etc. There are many such structures in the prior art, and they can be applied according to actual conditions, so as to ensure the stability between the measured claw unit, the adjusting seat and the turntable seat, and when the rotating driving member drives the turntable seat to rotate, the synchronous rotation of the measured claw unit can be maintained, wherein the driving mode of the rotating driving member includes but is not limited to motor direct drive, motor pulley drive, motor gear drive, etc. In the measurement process of the present application, the adjusting seat is first rotated outward by a certain angle away from the rotation axis, and the measured claw unit is installed on the offset adjusting seat. After the measured claw unit sinks a certain distance, the adjustment seat is driven to reset and coincide with the rotation axis. Since the measured claw unit is installed on the side away from the jump detection unit and sinks a certain distance after installation, the measured claw unit will not interfere with the jump detection unit even after rotation and reset. Instead, the movement path of the highest point of the measured claw unit is always kept below the jump detection unit, ensuring the reliability of the installation. During the disassembly process, the same principle can be applied. The measured claw unit is connected to the rotating seat and rotated to deviate from the rotation axis. Then, after the end of the measured claw unit is out of the influence range of the jump detection unit, the measured claw unit is taken out, thereby completing the entire detection process and reducing the probability of collision interference during the entire detection process.

Since the adjusting seat and the turntable seat are connected in a rotating manner, the flexibility of the adjusting seat can be guaranteed by the rotating connection. When the adjusting seat is rotated to coincide with the axis and the rotation axis, the adjusting seat and the rotation seat need to be kept relatively fixed. Therefore, in the present application, a positioning slide is provided in the adjusting seat, and the positioning slide can be slidably connected to the positioning block, and a positioning groove is provided in the turntable seat, wherein the positioning groove is provided at the center position of the turntable seat, that is, only when the axis of the adjusting seat is rotated to coincide with the rotation axis of the turntable seat can the positioning slide and the positioning groove be aligned, so that the positioning block can slide from the positioning slide to the positioning groove, and since the entire measured claw unit is placed vertically at this time, the pressure of the measured claw unit will be applied vertically above the positioning block, keeping the positioning block in the positioning groove, so that the positioning groove and the positioning slide are connected by the positioning block, so that the rotational freedom of the adjusting seat is limited by the positioning block, and when the measured claw unit is not interfered with by external force, it can only press on the positioning block, thereby maintaining the limiting function between the adjusting seat and the turntable seat. Furthermore, a positioning elastic member is connected between the positioning slot and the positioning block, and the positioning elastic member can provide the positioning block with an elastic pulling force away from the positioning slot, so that when the measured claw unit is disengaged from the positioning slot or the measured claw unit moves upward, the positioning elastic member can drive the positioning block to disengage from the positioning slot, and all are connected in the positioning slot, so that the positioning block limit is lost between the adjustment seat and the turntable seat, so that the adjustment seat can rotate again to change the offset angle of the axis, thereby driving the measured claw unit to disengage from the influence area of ​​the jump detection unit for disassembly.

[0008] Preferably, a limit slot is provided within the turntable seat, the limit slot being slidably connected to a limit block, and a limit elastic member is provided between the limit block and the turntable seat. A limit slot is further provided within the turntable seat, wherein the limit slot is slidably connected to the limit block. When the adjustment seat is rotated until the positioning slot is aligned with the limit slot, two situations may occur. When the cam is in the closed position, the stopper is engaged with the adjusting member and the stopper is engaged with the adjusting member, and the stopper is engaged with the adjusting member, and the stopper is engaged with the adjusting member, and the stopper is engaged with the adjusting member, and the stopper is engaged with the adjusting member, and the stopper is engaged with the adjusting member, and the stopper is engaged with the adjusting member, and the stopper is engaged with the adjusting member, And in the process of installing the measured claw unit, the adjustment seat can only be rotated after the measured claw unit sinks a certain distance, drives the positioning block to slide, and pushes the limit block to slide. The sinking distance is controlled within the range that can prevent the measured claw unit from interfering with the jump detection component during the rotation process, so that the adjustment seat can be unlocked to slide only after the measured claw unit reaches the movement standard, avoiding the movement of the adjustment seat when the measured claw unit has not moved into place.

[0009] Preferably, a positioning step is provided in the limiting groove, and when the limiting block abuts against the positioning step, the end face of the limiting block away from the positioning step is located on the interface between the adjustment seat and the turntable seat. A positioning step is provided in the limiting groove, wherein the positioning step can constrain the movement of the limiting block, preventing the limiting block from sliding along the limiting groove. Therefore, the positioning step is provided in such a manner that when the limiting block abuts against the positioning step, the side of the limiting block away from the positioning step is flush with the interface (interface) between the adjustment seat and the turntable seat, that is, at this position, a feedback signal can be given to the staff who installs the measured claw unit: the limiting block has been separated from the positioning groove, and the adjustment seat can be rotated.

The rotation limiting portion is configured as an inclined surface so that the rotation positioning plate can abut against the rotation positioning portion after the adjustment seat is tilted, thereby ensuring the stability of the abutment.

[0013] Preferably, a simulated placement piece is connected to one end of the measured claw unit remote from the turntable base. Providing the simulated placement piece on the measured claw unit can further improve the accuracy of measurement data from the runout detection unit. The simulated placement piece can be connected to the measured claw unit using methods including, but not limited to, snap-fit ​​and plug-fit connections, thereby ensuring that the simulated placement piece rotates synchronously with the measured claw unit.

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1: like Figure 1 、 2As shown, a quartz claw vibration testing device includes a support frame 1 and a turntable base 2, the turntable base 2 is connected to a rotating driving member 3, the support frame 1 is provided with an angle detection section 11, the angle detection section 11 is provided with a vibration detection unit 12, the turntable base 2 is rotatably connected to an adjustment base 4, the adjustment base 4 is connected to a measured claw unit 5, the measured claw unit 5 is detachably connected to the adjustment base 4, and the measured claw unit 5 can rotate relative to the support frame 1.

[0022] During the detection process of the quartz claw, since the light detection of the jump detection unit 12 is required, the jump detection component will produce an overlapping area with the claw unit 5 to be measured in the vertical direction. Since the jump detection unit 12 is connected to the angle detection section 11, there is an angle structure at the angle detection end, and there will be a section of structure extending close to the claw unit 5 to be measured. Therefore, in the process of installing the claw unit 5 to be measured, it is necessary to stagger the claw part of the claw unit 5 to be measured and the jump detection unit 12 as much as possible, and at the same time, it is necessary to align the bottom of the claw unit 5 to be measured with the turntable seat 2. This process needs to take into account the positions of both ends at the same time. If there is negligence, the claw unit 5 to be measured will collide and interfere with the jump detection unit 12, affecting the positioning accuracy and product safety.

[0023] Therefore, in order to address the above-mentioned problem, in the present application, an adjustment seat 4 is provided on the turntable seat 2. The adjustment seat 4 is capable of rotating on the turntable seat 2. A hole or a limiting device capable of connecting to the measured claw unit 5 is provided on the adjustment seat 4, such as a clamp, caliper, or collet structure. There are many such structures in the prior art and they can be applied according to actual conditions to ensure the stability between the measured claw unit 5, the adjustment seat 4, and the turntable seat 2. In this embodiment, a caliper 49 is installed on the adjustment seat for clamping. When the rotating drive member 3 drives the turntable seat 2 to rotate, the measured claw unit 5 can be kept in synchronous rotation. The driving method of the rotating drive member 3 includes but is not limited to direct motor drive, motor pulley drive, motor gear drive, etc. During the measurement process of the present application, the adjustment seat 4 is first rotated outwardly from the rotation axis by a certain angle, and the measured claw unit 5 is installed on the offset adjustment seat 4. After the measured claw unit 5 sinks a certain distance, the adjustment seat 4 is driven to reset and coincide with the rotation axis. Since the measured claw unit 5 is installed on the side away from the runout detection unit 12, and after installation, the measured claw unit 5 sinks a certain distance, so even after the rotation and reset, the detected claw unit 5 will not interfere with the run-out detection unit 12, but keep the movement path of the highest point of the detected claw unit 5 always below the run-out detection unit 12, ensuring the reliability of the installation. In the disassembly process, the detected claw unit 5 is connected to the rotating seat and rotated to deviate from the rotation axis. Then, after the end of the detected claw unit 5 is out of the influence range of the run-out detection unit 12, the detected claw unit 5 is taken out, thereby completing the entire detection process and reducing the probability of collision interference in the entire detection process.

[0024] like Figure 2 、 3 As shown, a positioning block 41 is slidably connected in the adjustment seat 4, a positioning groove 21 is provided at the center position of the turntable seat 2, a positioning slide 42 is provided in the adjustment seat 4, a positioning elastic member 43 is connected between the positioning slide 42 and the positioning block 41, the positioning slide 42 is slidably connected to the measured claw unit 5, the measured claw unit 5 can abut and push the positioning block 41 into the positioning groove 21, and the positioning elastic member 43 can drive the positioning block 41 to disengage from the positioning groove 21.

[0025] The adjustment seat 4 and the turntable seat 2 are connected in a rotating manner, and the flexibility of the adjustment seat 4 can be ensured by the rotating connection. When the adjustment seat 4 is rotated to coincide with the axis and the rotation axis, it is necessary to keep the adjustment seat 4 and the rotation seat relatively fixed. Therefore, in the present application, a positioning slot 42 is provided in the adjustment seat 4, and the positioning slot 42 can be slidably connected to the positioning block 41, and a positioning slot 21 is provided in the turntable seat 2, wherein the positioning slot 21 is provided at the center position of the turntable seat 2, that is, only when the axis of the adjustment seat 4 is rotated to coincide with the rotation axis of the turntable seat 2, can the positioning slot 42 be adjusted. and the positioning groove 21, so that the positioning block 41 can slide from the positioning slide 42 to the positioning groove 21, and because the entire measured claw unit 5 is placed vertically at this time, the pressure of the measured claw unit 5 will be applied vertically above the positioning block 41, keeping the positioning block 41 in the positioning groove 21, thereby connecting the positioning groove 21 and the positioning slide 42 through the positioning block 41, so that the rotational freedom of the adjustment seat 4 is limited by the positioning block 41, and when the measured claw unit 5 is not interfered with by external force, it can only press on the positioning block 41 to maintain the limiting function between the adjustment seat 4 and the turntable seat 2. Furthermore, a positioning elastic member 43 is connected between the positioning slot 42 and the positioning block 41. The positioning elastic member 43 can provide the positioning block 41 with an elastic pulling force away from the positioning slot 21, so that when the measured claw unit 5 disengages from the positioning slot 42 or the measured claw unit 5 moves upward, the positioning elastic member 43 can drive the positioning block 41 to disengage from the positioning slot 21, and all are connected in the positioning slot 42, so that the positioning block 41 is lost between the adjustment seat 4 and the turntable seat 2, so that the adjustment seat 4 can rotate again to change the offset angle of the axis, thereby driving the measured claw unit 5 to disengage from the influence area of ​​the jump detection unit 12 for disassembly.

[0026] like Figure 2 、 3As shown, the positioning groove 42 includes a narrow section 44 and a wide section 45, a step seat 46 is formed between the wide section 45 and the narrow section 44, and the measured claw unit 5 is connected between the step seat 46 and the positioning block 41. The size of the wide section 45 is larger than the size of the positioning groove 21, and the positioning block 41 includes a connecting portion 411 that can be clearance-matched with the wide section 45 and a positioning portion 412 that can be clearance-matched with the positioning groove 21. A narrow section 44 and a wide section 45 are provided in the positioning slot 42, wherein the cross-sectional dimension of the wide section 45 is larger, larger than the cross-sectional dimensions of the narrow section 44 and the positioning slot 21, the positioning block 41 is slidably connected in the wide section 45, and the cooperation between the positioning block 41 and the wide section 45 is a clearance cooperation, and on the basis of ensuring sliding, the cooperation clearance is minimized to the greatest extent, the accuracy of positioning is ensured, and the influence of the clearance on the runout detection is reduced, and the positioning elastic member 43 is connected to the step seat 46 formed between the narrow section 44 and the wide section 45, so that the positioning elastic member 43 will not affect the contact between the measured claw unit 5 and the positioning block 41, nor will it affect the contact between the adjustment seat 4 and the turntable seat 2 The rotation between the adjusting seat 4 and the turntable seat 2 is controlled by the positioning block 41, and the positioning block 41 includes a connecting portion 411 and a positioning portion 412. The connecting portion 411 is a portion that is loosely fitted with the wide section 45, while the cross-sectional dimensions of the positioning portion 412 are adapted to the cross-sectional dimensions of the positioning groove 21, so that the positioning portion 412 can be loosely fitted with the positioning groove 21, thereby ensuring the fixing accuracy between the adjusting seat 4 and the turntable seat 2. At the same time, by using the positioning block 41 to position and fix the adjusting seat 4 and the turntable seat 2, the influence of the relative sliding tendency between the adjusting seat 4 and the turntable seat 2 on the measured claw unit 5 is avoided. The stability of the measured claw unit 5 is ensured by the positioning block 41 taking full responsibility. In the figure, for easy identification, there is a large gap between the positioning block and the limit block and the corresponding positioning groove, limit groove, and positioning groove. In actual implementation, it is preferred to fit closely and ensure the minimum gap.

[0027] like Figure 2 、 3As shown, a limit slot 22 is provided in the turntable seat 2, which is slidably connected to a limit block 23. A limit elastic member 24 is provided between the limit block 23 and the turntable seat 2. The turntable seat 2 is further provided with a limit slot 22, in which the limit block 23 is slidably connected. When the adjustment seat 4 is rotated until the positioning slot 42 is aligned with the limit slot 22, two situations can occur. First, the measured claw unit 5 is connected to the positioning slot 42, the measured claw unit 5 presses the positioning block 41, and the positioning block 41 presses the limit block 23, so that the limit block 23 is completely located in the limit slot 22, and the positioning block 41 is completely located in the positioning slot 42, that is, the intersection of the limit block 23 and the positioning block 41 is the intersection of the adjustment seat 4 and the turntable seat 2, and the adjustment seat 4 can be rotated freely at this time; second, when there is no measured claw unit 5 in the adjustment seat 4, the limit elastic member 24 in the limit slot 22 will push the limit block 23 to pass through the adjustment seat 4 and the turntable seat 2 The interface is connected to the positioning slot 42, wherein the size of the limit block 23 can be adapted to the size of the positioning slot 42, and a clearance fit is performed. Therefore, when the limit block 23 is connected to the positioning slot 42, the adjustment seat 4 and the turntable seat 2 can also be limited and fixed, so that the adjustment seat 4 can be maintained at a specific offset angle. This position is the initial position of the adjustment seat 4, which is convenient for the next installation of the measured claw unit 5. It can be installed directly at the offset position, avoiding the measured claw unit 5 being installed in the same way as in the prior art due to forgetfulness. In the process of installing the measured claw unit 5, the adjustment seat 4 can only be rotated after the measured claw unit 5 sinks a certain distance, drives the positioning block 41 to slide, and pushes the limit block 23 to slide. The sinking distance is controlled within a range that can prevent the measured claw unit 5 from interfering with the jump detection component during the rotation process. Therefore, the sliding of the adjustment seat 4 can be unlocked only after the measured claw unit 5 reaches the movement standard, avoiding the movement of the adjustment seat 4 when the measured claw unit 5 has not moved into place.

[0028] like Figure 2 、 3 As shown, a positioning step 25 is provided in the limiting chute 22. When the limiting block 23 abuts against the positioning step 25, the end face of the limiting block 23 away from the positioning step 25 is located on the interface between the adjustment seat 4 and the turntable seat 2. The positioning step 25 is provided in the limiting chute 22, wherein the positioning step can constrain the movement of the limiting block 23 and prevent the limiting block 23 from sliding along the limiting chute 22. Therefore, the positioning step 25 is set in a position such that when the limiting block 23 abuts against the positioning step 25, the side of the limiting block 23 away from the positioning step 25 is flush with the interface (interface) between the adjustment seat 4 and the turntable seat 2. That is, at this position, a feedback signal can be given to the staff installing the measured claw unit 5: the limiting block 23 has disengaged from the positioning chute 42 and the adjustment seat 4 can be rotated.

[0029] like Figure 2 、 3As shown, the end surface of the limit block 23 near the adjustment seat 4 can be adapted to fit the curved surface of the adjustment seat 4, and the end surface of the positioning block 41 near the turntable seat 2 can be adapted to fit the curved surface of the turntable seat 2. The curved surfaces of the adjustment seat 4 and the turntable seat 2 can fit together and rotate relative to each other. The facing end surfaces of the limit block 23 and the positioning block 41 are both curved surfaces that can adapt to rotation, thereby avoiding interference with the relative rotation of the adjustment seat 4 and the turntable seat 2.

[0030] like Figure 2 、 3 As shown, a simulated placement piece 51 is connected to the end of the measured claw unit 5 away from the turntable base 2. Providing the simulated placement piece 51 on the measured claw unit 5 enables more accurate measurement data from the runout detection unit 12. The connection between the simulated placement piece 51 and the measured claw unit 5 includes, but is not limited to, a snap-fit ​​connection and a plug-fit connection, thereby ensuring that the simulated placement piece 51 can rotate synchronously with the measured claw unit 5. The runout detection unit 12 uses laser ranging as a detection method. The changes in the data detected by the simulated placement piece 51 during rotation reflect the runout value of the measured claw unit 5, resulting in more accurate data.

[0031] like Figure 2 、 3 As shown, the runout test unit includes a radial detection member 121 and an axial detection member 122, and the radial detection member 121 and the axial detection member 122 are respectively placed on the vertical and horizontal areas of the angle detection section 11. By setting the radial detection member 121 and the axial detection member 122, it can be ensured that the detection in this embodiment can be staggered by rotating the above structure, so that the end of the quartz claw can avoid the detection equipment and reduce the risk of interference and collision; the positioning block 41 can slide freely in the positioning slot 42 and the positioning slot 21, and cooperate with the gravity of the measured claw unit 5 to squeeze, so as to maintain the relative fixation between the adjustment seat 4 and the turntable seat 2, and at the same time, the positioning elastic member 43 can drive the positioning block 41 to return and unlock the fixed state; the limit block 23 can be used to move in the positioning slot 42 and the limit slot The adjusting seat 4 can slide freely in the positioning slot 22, thereby being able to fix the initial position of the adjusting seat 4, so that when the measured claw unit 5 is not installed, the adjusting seat 4 can be fixed in this position, which is convenient for the installation of the measured claw unit 5. At the same time, the adjusting seat 4 can be rotated only after the measured claw unit 5 is installed in place; by rotating the positioning plate 47 and the horizontal positioning plate 48 and the reset elastic member 28, the extreme position can be limited, helping the positioning block 41 and the limit block 23 to connect the adjusting seat 4 and the turntable seat 2, and through the reset elastic member 28, a self-resetting effect is achieved, so that when the measured claw unit 5 is installed, the adjusting seat 4 is oriented in a unified direction.

[0032] Example 2: like Figure 2 、 3As shown, the adjustment seat 4 includes a rotation positioning plate 47 and a horizontal positioning plate 48 provided on both sides, and the turntable seat 2 includes a rotation limiting portion 26 provided corresponding to the rotation positioning plate 47 and a horizontal limiting portion 27 provided corresponding to the horizontal positioning plate 48, and a reset elastic member 28 is provided between the rotation positioning plate and the rotation limiting portion 26. Two limit position limiting structures are provided on the adjustment seat 4: a rotation positioning plate 47 and a horizontal positioning plate 48, wherein the rotation positioning plate 47 can abut against the rotation limiting portion 26 on the turntable seat 2. After abutting, the adjustment seat 4 rotates to the limit position, at which time the positioning slot 42 on the adjustment seat 4 is aligned with the limiting slot 22 on the turntable seat 2; when the horizontal positioning plate 48 abuts against the horizontal limiting portion 27, the axis of the positioning slot 42 on the adjustment seat 4 coincides with the rotation axis of the turntable seat 2. At this time, the limit position is set. The positioning slot 42 is aligned with the positioning slot 21, and a reset elastic member 28 is provided between the rotating positioning plate and the rotating limiting portion 26. This allows, when the positioning block 41 is disengaged from the positioning slot 21, the elastic reset member can pull the rotating positioning plate 47 close to the rotating positioning portion 412, thereby realizing the rotation of the adjustment seat 4, and then ensuring that the adjustment seat 4 can spontaneously return to the initial position (the positioning slot 42 is aligned with the limiting slot 22), so that before each detection begins, the adjustment seat 4 can be located in the initial position.

[0033] like Figure 2 、 3 As shown, the rotation limit portion 26 is an inclined surface. When the return elastic member 28 drives the rotation positioning plate 47 to abut against the rotation limit portion 26, the rotation positioning plate 47 abuts against the inclined surface of the rotation limit portion 26. The rotation limit portion 26 is configured as an inclined surface so that the rotation positioning plate 47 can abut against the rotation positioning portion 412 after the adjustment seat 4 is tilted, thereby ensuring the stability of the abutment.

[0034] This embodiment also includes a support frame 1 and a turntable seat 2. The turntable seat 2 is connected to a rotating drive member 3. The support frame 1 is provided with a folding angle detection section 11. The folding angle detection section 11 is provided with a jump detection unit 12. The turntable seat 2 is rotatably connected to an adjustment seat 4. The adjustment seat 4 is connected to a measured claw unit 5. The measured claw unit 5 is detachably connected to the adjustment seat 4 and can rotate relative to the support frame 1. A positioning block 41 is slidably connected in the adjustment seat 4. A positioning groove 21 is provided at the center position of the turntable seat 2. A positioning slide 42 is provided in the adjustment seat 4. A positioning elastic member 43 is connected between the positioning slide 42 and the positioning block 41. The positioning slide 42 is slidably connected to the measured claw unit 5. The measured claw unit 5 can abut against and push the positioning block 41 into the positioning groove 21. The positioning elastic member 43 can drive the positioning block 41 out of the positioning groove 21. The positioning groove 42 includes a narrow section 44 and a wide section 45. A step seat 46 is formed between the wide section 45 and the narrow section 44. The measured claw unit 5 is connected between the step seat 46 and the positioning block 41. The wide section 45 is larger than the positioning groove 21. The positioning block 41 includes a connecting portion 411 that can be loosely matched with the wide section 45 and a positioning portion 412 that can be loosely matched with the positioning groove 21. A limiting groove 22 is provided in the turntable seat 2. The limiting groove 22 is slidably connected to the limiting block 23. A limiting elastic member 24 is provided between the limiting block 23 and the turntable seat 2. A limiting groove 22 is also provided in the turntable seat 2, wherein the limiting groove 22 is slidably connected to the limiting block 23. When the adjustment seat 4 is rotated until the positioning groove 42 is aligned with the limiting groove 22, two situations can occur. A positioning step 25 is provided within the limiting chute 22. When the limiting block 23 abuts the positioning step 25, the end surface of the limiting block 23 facing away from the positioning step 25 is located at the interface between the adjustment seat 4 and the turntable seat 2. The end surface of the limiting block 23 near the adjustment seat 4 can fit snugly with the curved surface of the adjustment seat 4, and the end surface of the positioning block 41 near the turntable seat 2 can fit snugly with the curved surface of the turntable seat 2, allowing the curved surfaces of the adjustment seat 4 and the turntable seat 2 to fit and rotate relative to each other.

[0035] The end of the tested claw unit 5 away from the turntable base 2 is connected to a simulation placement piece 51. The runout test unit includes a radial detection piece 121 and an axial detection piece 122, which are respectively placed on the vertical and horizontal areas of the corner detection section 11.

[0036] By providing a simulated placement piece 51 on the measured claw unit 5, the measurement data of the runout detection unit 12 can be made more accurate. The connection between the simulated placement piece 51 and the measured claw unit 5 includes, but is not limited to, a snap-fit ​​connection and a plug-in connection, thereby ensuring that the simulated placement piece 51 can rotate synchronously with the measured claw unit 5. The runout detection unit 12 uses laser ranging as the detection data changes detected by the simulated placement piece 51 during rotation to reflect the runout value of the measured claw unit 5, making the data more accurate. The provision of radial detection components 121 and axial detection components 122 ensures the comprehensiveness of the detection data, and the angle detection section 11 can be used to achieve different installation positions.
