[0001] This application relates to the field of integrated machine calibration technology, and in particular to an integrated machine accuracy calibration device. Background Technology

[0002] After the servo all-in-one machine has finished processing, it is usually necessary to calibrate the encoder of the servo all-in-one machine.

[0003] However, existing calibration devices can only calibrate a single type of servo all-in-one machine, which has poor versatility and results in high costs for manufacturers. Utility Model Content

[0006] The base is equipped with a receiving cavity and a support plate located on one side of the receiving cavity, and the support plate has a first through hole communicating with the receiving cavity;

[0007] A driving component is disposed in the base, and the first output shaft of the driving component is disposed facing the side of the support plate;

[0008] A coupling is connected to the first output shaft;

[0009] The first clamping unit is installed on the side of the support plate away from the accommodating cavity. The clamping unit includes at least two sets of first clamping mechanisms, which are arranged around the periphery of the first through hole.

The minimum distance between the end of the second clamping mechanism facing the central axis of the first through hole and the central axis is different from the minimum distance between the end of the first clamping mechanism facing the central axis and the central axis.

[0011] In some possible implementations, the first clamping mechanism includes:

The limiting edge abuts against the side of the second connecting rod opposite to the first connecting rod.

[0021] In some possible implementations, the integrated precision calibration device further includes a third clamping unit, which is mounted on the side of the support plate opposite to the receiving cavity;

[0022] The third clamping unit includes at least two sets of third clamping mechanisms. The at least two sets of third clamping mechanisms are arranged around the first through hole and are offset from the first clamping mechanism and the second clamping mechanism. The minimum distance between the end of the third clamping mechanism facing the central axis and the central axis is different from the minimum distance between the end of the first clamping mechanism facing the central axis and the central axis, and the minimum distance between the end of the second clamping mechanism facing the central axis and the central axis.

[0028] The beneficial effects of this application are as follows: The integrated machine precision calibration device provided by this application includes a first clamping unit and a second clamping unit. The minimum distance between the end of the first clamping mechanism facing the central shaft of the first through hole and the central shaft is different from the minimum distance between the end of the second clamping mechanism facing the central shaft and the central shaft.

[0058] like Figure 1 As shown in the figure, an all-in-one machine precision calibration device (hereinafter referred to as calibration device 1000) is provided in the embodiment, which can be used to calibrate the precision of the encoder in the all-in-one machine. The all-in-one machine can be a servo all-in-one machine.

[0059] like Figures 1 to 4 as well as Figures 9 to 11As shown, the calibration device 1000 may include a base 100, a drive unit 200, a coupling 640, a first clamping unit 301, and a second clamping unit 401.

[0060] The base 100 serves as a mounting carrier in the calibration device 1000, and other structural components can be attached to the base 100 for installation. In some embodiments, the base 100 may have a quadrilateral frame structure with a receiving cavity 101 formed inside. Additionally, the base 100 includes a support plate 110 located on one side of the receiving cavity 101. In some embodiments, the support plate 110 may be located at the top of the base 100, i.e., on the side of the base 100 away from the ground. A first through hole 111 communicating with the receiving cavity 101 may be formed on the support plate 110.

[0061] The drive unit 200 can be installed in the receiving cavity 101 and can be fixedly connected to the base 100. The first output shaft 210 of the first drive unit 200 can face the support plate 110 and can be coaxial with the first through hole 111. In some embodiments, the drive unit 200 can be a motor.

[0062] The coupling 640 can be fixedly connected to the first output shaft 210 of the drive member 200, and the coupling 640 can be coaxially arranged with the first output shaft 210. Thus, the drive member 200 can drive the coupling 640 to rotate.

[0063] In some embodiments, both the first clamping unit 301 and the second clamping unit 401 are mounted on the side of the support plate 110 away from the receiving cavity 101. The first clamping unit 301 may include at least two sets of first clamping mechanisms 300, and the second clamping unit 401 may include at least two sets of second clamping mechanisms 400. The at least two sets of first clamping mechanisms 300 and at least two sets of second clamping mechanisms 400 are arranged around the periphery of the first through hole 111 and are staggered relative to each other. In the embodiments, both the first clamping mechanism 300 and the second clamping mechanism 400 are configured to provide a clamping force perpendicular to the support plate 110, which can clamp and fix the integrated machine 2000 to be calibrated onto the base 100. For example, when the integrated machine 2000 to be calibrated is clamped and fixed by the first clamping unit 301, at least two first clamping mechanisms 300 can cooperate to clamp the integrated machine 2000 to be calibrated, and the integrated machine 2000 to be calibrated can be clamped and fixed relative to the base 100.

[0064] In some embodiments, the minimum distance between the end of the first clamping mechanism 300 facing the central axis L of the first through hole 111 and the central axis L is different from the minimum distance between the end of the second clamping mechanism 400 facing the central axis L and the central axis L. Therefore, the first clamping unit 301 and the second clamping unit 401 can be adapted to different models of the integrated machine 2000 to be calibrated, and different models of the integrated machine 2000 to be calibrated can be pressed onto the calibration device 1000 by either the first clamping unit 301 or the second clamping unit 401, improving the versatility of the calibration device 1000.

[0065] like Figures 1 to 3 as well as Figure 11 As shown, in some embodiments, the drive component 200 can be fixedly mounted in the receiving cavity 101 of the base 100 via a mounting flange 610. Specifically, one end of the mounting flange 610 can be fixedly connected to the side of the support plate 110 facing the receiving cavity 101 via bolts or other means. The main structure of the drive component 200 can be fixedly connected to the side of the mounting flange 610 away from the support plate 110 via bolts or other means. Furthermore, the first output shaft 210 of the drive component 200 can pass through the mounting flange 610 and extend into the interior of the mounting flange 610. In some embodiments, the coupling 640 can be accommodated within the mounting flange 610 and fixedly sleeved on the first output shaft 210.

[0066] In some embodiments, the mounting flange 610 may have a second through hole 611 at one end facing the support plate 110, which is opposite to and communicates with the first through hole 111. The coupling 640 may be exposed on the side of the support plate 110 away from the receiving cavity 101 through the second through hole 611 and the first through hole 111 in sequence. Accordingly, the second output shaft 2200 of the integrated machine 2000 to be calibrated may be passed through the first through hole 111 and the second through hole 611 in sequence, and may extend into the interior of the mounting flange 610 to connect with the coupling 640, so as to realize the transmission connection between the drive member 200 and the integrated machine 2000 to be calibrated.

[0067] like Figures 1 to 3 as well as Figure 11 As shown, in some embodiments, the mounting flange 610 has a recess 612 surrounding the second through hole 611 on the side facing the support plate 110. The calibration device 1000 may also include a connecting flange 620. During use, the connecting flange 620 is detachably connected to the main structure of the integrated machine 2000 to be calibrated. For example, the connecting flange 620 can be connected to the main structure of the integrated machine 2000 to be calibrated by means of bolts or the like.

[0068] In some embodiments, the outer peripheral shape of the connecting flange 620 can be adapted to the shape of the recess 612. During calibration, the connecting flange 620 can be placed in the recess 612, and the sidewalls of the connecting flange 620 can fit against the inner wall of the recess 612. This allows the upper limit of the connecting flange 620 in the direction parallel to the support plate 110 to be located within the recess 612, thus limiting the horizontal movement of the connecting flange 620 relative to the support plate 110. Furthermore, this achieves horizontal limitation of the integrated machine 2000 to be calibrated, preventing the integrated machine 2000 to be calibrated from moving arbitrarily horizontally relative to the base 100.

[0069] In other embodiments, the main structure of the integrated machine 2000 to be calibrated may also directly abut against the side of the support plate 110 away from the accommodating cavity 101, and the integrated machine 2000 to be calibrated may be pressed and fixed on the support plate 110 by the first clamping unit 301 or the second clamping unit 401, which can prevent the integrated machine 2000 to be calibrated from moving in a direction parallel to the support plate 110, and at the same time, can also prevent the integrated machine to be calibrated from moving in a direction perpendicular to the support plate 110.

[0070] In this embodiment, the shape of the periphery of the connecting flange 620 can be adapted to the shape of the settling tank 612. The structural shape of the connecting flange 620, used to connect the integrated machine 2000 to be calibrated, can be adapted to the integrated machine 2000 to be calibrated. When different models of integrated machines 2000 need to be calibrated, the connecting flange 620 can be replaced, and a connecting flange 620 adapted to the integrated machine 2000 to be calibrated can be selected. Thus, the calibration equipment 1000 can be easily adapted to different models of integrated machines 2000 to be calibrated, so that different models of integrated machines 2000 can be calibrated using the same calibration equipment 1000.

[0071] In some embodiments, the calibration device 1000 further includes an adapter sleeve 630. During use, the adapter sleeve 630 can be fitted onto the second output shaft 2200 of the integrated machine 200 to be calibrated and is detachably connected to the second output shaft 2200. It is understood that when the adapter sleeve 630 is fitted onto the second output shaft 2200, the adapter sleeve 630 can be limited in the rotation direction of the second output shaft 2200, that is, the adapter sleeve 630 can rotate synchronously with the second output shaft 2200. Additionally, the adapter sleeve 630 can be plugged into and inserted into the coupling 640, that is, the adapter sleeve 630 and the coupling 640 are also detachably connected. It is understood that the side of the adapter sleeve 630 used to connect to the integrated machine 2000 to be calibrated can be adapted to the second output shaft 2200 of the integrated machine 2000 to be calibrated. The side of the adapter sleeve 630 facing the coupling 640 can be adapted to the coupling 640.

[0072] When calibrating integrated machines 2000 of the same model but with different second output shafts 2200, or different models of integrated machines 2000 to be calibrated, different adapter sleeves 630 can be replaced to adapt to the second output shafts 2200 of different integrated machines 2000 to be calibrated. Thus, the calibration equipment 1000 can perform calibration work on different integrated machines 2000 to be calibrated.

[0073] In addition, when the adapter sleeve 630 is connected to the coupling 640, the adapter sleeve 630 and the coupling 640 can be connected at the upper limit in the rotation direction of the first output shaft 210, that is, the coupling 640 can drive the adapter sleeve 630 to rotate synchronously.

[0074] During the calibration process, the drive component 200 can drive the coupling 640 to rotate, and the coupling 640 can drive the second output shaft 2200 of the integrated machine 200 to be calibrated to rotate through the adapter sleeve 630, so as to realize the calibration of the integrated machine 2000 to be calibrated.

[0075] like Figure 1 and Figure 2 As shown, in some embodiments, the calibration device 1000 further includes an electrically connected driver 710 and a power supply 720. Both the driver 710 and the power supply 720 are fixedly connected to the inner wall of the base 100 facing the receiving cavity 101 by means of screws or other methods; that is, both the driver 710 and the power supply 720 are housed within the receiving cavity 101 of the base 100. The driver 710 can be a motor driver, electrically connected to the driving member 200, thereby driving the driving member 200 to operate. Additionally, the power supply 720 can supply power to other electrical components in the calibration device 1000 to ensure the normal operation of the calibration device 1000.

[0076] like Figure 1 , Figures 4 to 7 , Figures 9 to 11 As shown, in some embodiments, the first clamping unit 301 may include two sets of first clamping mechanisms 300, which may be symmetrically arranged about the central axis L, that is, the two sets of first clamping mechanisms 300 are arranged opposite to each other.

[0077] In other embodiments, the first clamping unit 301 may also include three, four, or more sets of first clamping mechanisms 300. The multiple sets of first clamping mechanisms 300 may be distributed around the periphery of the first through hole 111, and may be uniformly or non-uniformly distributed.

[0078] In some embodiments, the first clamping mechanism 300 may include a pressure rod 310 and a pressure module 320. One end of the pressure rod 310 is rotatably connected to the support plate 110. The other end of the pressure rod 310 may be configured as a pressure head 311, which may be a movable end and can rotate about the connection between the pressure rod 310 and the support plate 110. In this embodiment, the pressure head 311 can rotate to be suspended relative to the first through hole 111 and opposite to the countersunk groove 612 of the mounting flange 610.

[0079] In some embodiments, the pressure module 320 may include a first mounting base 321, a first drive handle 322, an adapter rod assembly 323, and a first pressure head 325. The first mounting base 321 is fixedly mounted to the support plate 110 by means of bolts or welding. One end of the first drive handle 322 is rotatably connected to the first mounting base 321. The other end of the first drive handle 322 may be configured as a first operating end 3221. An operator can use the first operating end 3221 to rotate the first drive handle 322 relative to the first mounting base 321.

[0080] In this embodiment, one end of the adapter rod assembly 323 can also be rotatably connected to the first mounting base 321, and the first pressure head 325 can be connected to the other end of the adapter rod assembly 323 away from the first mounting base 321. Furthermore, the adapter rod assembly 323 is connected to the first drive handle 322 via a transmission connection. The user can rotate the first drive handle 322 relative to the first mounting base 321, and the first drive handle 322 can drive the adapter rod assembly 323 to move the first pressure head 325 closer to or away from the support plate 110.

[0081] Additionally, when the pressure head 311 moves above the pressing part 2100 of the integrated machine 2000 to be calibrated, the pressure rod 310 can be located on the moving path of the first pressure head 325. During use, the first pressure head 325 can press the pressure head 311 against the pressing part 2100 of the integrated machine 2000 to be calibrated.

[0082] In some embodiments, the adapter rod assembly 323 may include a first connecting rod 3231 and a second connecting rod 3232. One end of the first connecting rod 3231 is rotatably connected to the first mounting base 321. One end of the second connecting rod 3232 is connected to the end of the first connecting rod 3231 away from the first mounting base 321. The second connecting rod 3232 may be located on the side of the first connecting rod 3231 facing away from the support plate 110. A first pressure head 325 may be fixedly connected to the end of the second connecting rod 3232 away from the first connecting rod 3231 by means of screwing, snap-fitting, or interference fit, and the first pressure head 325 may protrude from the side of the second connecting rod 3232 facing the support plate 110.

[0083] In some embodiments, the pressure module 320 further includes a transmission rod 324. One end of the transmission rod 324 is rotatably connected to the first drive handle 322. The connection position between the transmission rod 324 and the first drive handle 322 may be located between the connection position of the first operating end 3221 and the connection position of the first drive handle 322 and the first mounting base 321. The other end of the transmission rod 324 is rotatably connected to the first connecting rod 3231. The connection position between the transmission rod 324 and the first connecting rod 3231 may be located between the connection position of the first connecting rod 3231 and the first mounting base 321 and the connection position of the second connecting rod 3232 and the first connecting rod 3231.

[0084] When the operator rotates the first drive handle 322 relative to the first mounting base 321, the transmission rod 324 can drive the adapter rod assembly 323 to rotate, and the adapter rod assembly 323 can then drive the first pressure head 325 to move away from or closer to the bearing plate 110.

[0085] In other embodiments, the first drive handle 322 may be integral with the first connecting rod 3231 and may be V-shaped. The connection between the first drive handle 322 and the first connecting rod 3231 is rotatably connected to the first mounting base 321. The first operating end 3221 may be located at the end of the first drive handle 322 away from the first connecting rod 3231. When the operator rotates the first drive handle 322, it can drive the first connecting rod 3231 to rotate synchronously, thereby driving the first pressure head 325 to move closer to or away from the support plate 110.

[0086] In some embodiments, the second connecting rod 3232 is detachably connected to the first connecting rod 3231. Furthermore, the connection position between the second connecting rod 3232 and the first connecting rod 3231 is adjustable along the axial direction of the first connecting rod 3231. That is, the position of the second connecting rod 3232 relative to the first connecting rod 3231 can be adjusted.

[0087] In some embodiments, the end of the first connecting rod 3231 away from the first mounting base 321 may have a first oblong hole 32311, the length direction of which may be parallel to the axial direction of the first connecting rod 3231. The end of the second connecting rod 3232 near the first connecting rod 3231 may have a connecting hole 32321. In addition, the adapter rod assembly 323 also includes a first locking member 3233, which can be used to lock the relative position of the first connecting rod 3231 and the second connecting rod 3232.

[0088] In some embodiments, the first locking member 3233 may include an integral connecting rod portion 32331 and a limiting edge 32332, with the limiting edge 32332 located at one end of the connecting rod portion 32331. In this embodiment, the connecting rod portion 32331 may pass sequentially through the connecting hole 32321 and the first oblong hole 32311. The end of the connecting rod portion 32331 away from the limiting edge 32332 may protrude relative to the side of the first connecting rod 3231 facing the support plate 110 and may be locked with a nut 800. The limiting edge 32332 may tightly abut against the side of the second connecting rod 3232 opposite to the first connecting rod 3231. Thus, the first connecting rod 3231 and the second connecting rod 3232 can be locked and fixed, preventing the second connecting rod 3232 from moving freely relative to the first connecting rod 3231. When the position of the second connecting rod 3232 needs to be adjusted, the nut 800 and the first locking member 3233 can be rotated relative to each other to separate the limiting edge 32332 of the first locking member 3233 from the second connecting rod 3232, thereby unlocking the second connecting rod 3232 from the first connecting rod 3231. This allows the operator to adjust the position of the second connecting rod 3232 relative to the first connecting rod 3231. Once adjusted to the correct position, the first connecting rod 3231 and the second connecting rod 3232 can be locked and fixed in place by the cooperation of the first locking member 3233 and the nut 800.

[0089] In other embodiments, the end of the connecting rod portion 32331 away from the limiting edge 32332 can also be fixedly connected to the inner wall of the first waist-shaped hole 32311 by means of tight fitting or the like.

[0090] In this embodiment, the position of the first pressure head 325 can be adjusted by adjusting the relative position of the second connecting rod 3232 and the first connecting rod 3231, so that the first pressure head 325 can accurately press against the pressure rod 310, so as to adapt to different calibration all-in-one machines 2000 and further improve the versatility of the calibration equipment 1000.

[0091] When the corresponding integrated machine 2000 to be calibrated is clamped and fixed onto the calibration equipment 1000 by the first clamping unit 301, the pressure head 311 can be rotated to one side of the first through hole 111, and the first pressure head 325 can be lifted relative to the pressure rod 310 by the first drive handle 322 to provide clearance for the integrated machine 2000 to be calibrated, making it easier for the operator to install the integrated machine 2000 to be calibrated onto the calibration equipment 1000. Subsequently, the pressure rod 310 can be rotated so that the pressure head 311 of the pressure rod 310 rotates to the side of the pressing part 2100 of the integrated machine 2000 away from the mounting flange 610. The pressure head 311 is limited to the groove on the side wall of the corresponding position of the integrated machine 2000 to be calibrated, and is upper limit abutted in the rotation direction of the second output shaft 2200. Subsequently, the first drive handle 322 can be rotated so that the first pressure head 325 presses against the pressure rod 310, so that the pressure head 311 presses against the pressing part 2100 of the integrated machine 2000 to be calibrated.

[0092] like Figures 1 to 4 As shown, in some embodiments, the second clamping unit 401 may include two sets of second clamping mechanisms 400, which may be arranged opposite to each other. When the second clamping unit 401 is used, the two sets of second clamping units 401 can cooperate to clamp and fix the integrated machine 2000 to be calibrated.

[0093] In other embodiments, the second clamping unit 401 may also include three, four, or other sets of second clamping mechanisms 400. The sets of second clamping mechanisms 400 may be arranged around the periphery of the first through hole 111 and may be uniformly or non-uniformly distributed.

[0094] In some embodiments, the structure of the second clamping mechanism 400 may be similar to that of the pressure module 320 in the first clamping mechanism 300, and will not be described in detail here. The usage of the second clamping mechanism 400 may be similar to that of the pressure module 320 acting on the pressure rod 310, and will not be described in detail here. In addition, the extension direction of the second clamping mechanism 400 may be approximately parallel to the view of the first through hole 111.

[0095] like Figures 1 to 4 as well as Figures 8 to 11As shown, in some embodiments, the calibration device 1000 may further include a third clamping unit 501, which may include at least two sets of third clamping mechanisms 500. The third clamping mechanism 500 may also be disposed on the periphery of the first through hole 111 and offset from the first clamping mechanism 300 and the second clamping mechanism 400. In some embodiments, the minimum distance between the end of the third clamping mechanism 500 closest to the central axis L of the first through hole 111 and the central axis L may differ from the minimum distance between the end of the first clamping mechanism 300 facing the central axis L and the central axis L, and the minimum distance between the end of the second clamping mechanism 400 facing the central axis L and the central axis L. Therefore, the third clamping unit 501 can be adapted to other different integrated calibration devices 2000, further improving the versatility of the calibration device 1000.

[0096] In some embodiments, the third clamping unit 501 may include two sets of third clamping mechanisms 500, which may be arranged opposite to each other. When the third clamping unit 501 is used, the two sets of third clamping units 501 can cooperate to clamp and fix the integrated machine 2000 to be calibrated.

[0097] In other embodiments, the third clamping unit 501 may also include three, four, or other sets of third clamping mechanisms 500. The sets of third clamping mechanisms 500 may be arranged around the periphery of the first through hole 111 and may be uniformly or non-uniformly distributed.

[0098] In some embodiments, the third clamping mechanism 500 may include a second mounting base 510, a second drive handle 520, a third connecting rod 530, and a second pressure head 540. The second mounting base 510 may be fixedly mounted on the support plate 110 by means of bolts or welding. In an embodiment, one end of the second drive handle 520 is rotatably connected to the second mounting base 510. The other end of the second drive handle 520 may be used as a second operating end 521. An operator may use the second operating end 521 to push the second drive handle 520 to rotate relative to the second mounting base 510.

[0099] In some embodiments, the end of the second drive handle 520 away from the second operating end 521 can be rotatably connected to the second mounting base 510 via a fourth connecting rod 550. Specifically, one end of the fourth connecting rod 550 can be rotatably connected to the end of the second drive handle 520 away from the second operating end 521, and the other end of the fourth connecting rod 550 is rotatably connected to the second mounting base 510. In some embodiments, the fourth connecting rod 550 can be generally in the form of an arc-shaped rod.

[0100] In some embodiments, one end of the third connecting rod 530 may be rotatably connected to the second mounting base 510. The end of the third connecting rod 530 near the second mounting base 510 may also be rotatably connected to the end of the second drive handle 520 away from the second operating end 521. In some embodiments, the end of the third connecting rod 530 facing the second mounting base 510 may be approximately triangular. The connection position between the second mounting base 510 and the third connecting rod 530 may be located at two corners of the triangle, opposite to the connection position between the second drive handle 520 and the third connecting rod 530. In one embodiment, the connection position between the third connecting rod 530 and the second drive handle 520 may be located on the side of the second drive handle 520 and the fourth connecting rod 550 that is away from the second operating end 521.

[0101] The second pressure head 540 can be connected to the end of the third connecting rod 530 away from the second drive handle 520. The second pressure head 540 can protrude relative to the third connecting rod 530 toward the support plate 110.

[0102] During use, the operator can push the second drive handle 520 to rotate through the second operating end 521. During the rotation of the second drive handle 520, the third connecting rod 530 can be driven to rotate relative to the second mounting base 510, so that the second pressure head 540 moves closer to or further away from the bearing plate 110.

[0103] In some embodiments, the position of the second pressure head 540 on the third connecting rod 530 is adjustable along the axial direction of the third connecting rod 530. In some embodiments, the axial direction of the third connecting rod 530 may be substantially parallel to the radial direction of the first through hole 111.

[0104] The end of the third connecting rod 530 furthest from the second mounting base 510 may have a second oblong hole 531, the length of which may be parallel to the axial direction of the third connecting rod 530. One end of the second pressure head 540 may pass through the second oblong hole 531 and be locked to the third connecting rod 530 by a nut 800. When it is necessary to adjust the position of the second pressure head 540 relative to the third connecting rod 530, the second pressure head 540 and the nut 800 may be loosened to adjust the position of the second pressure head 540 in the second oblong hole 531. After adjustment, the second pressure head 540 may be locked to the third connecting rod 530 by the nut 800.

[0105] When the integrated machine to be calibrated 2000 is clamped by the third clamping unit 501, the second pressure head 540 can be lifted relative to the mounting flange 610 by the second drive handle 520 to provide clearance for the integrated machine to be calibrated 2000, making it easier for the operator to install the integrated machine to be calibrated 2000 on the calibration equipment 1000. Subsequently, the second drive handle 520 can be rotated so that the second pressure head 540 presses against the pressing part 2100 of the integrated machine to be calibrated 2000, and the side wall of the second pressure head 540 can abut against the upper limit of the main structure of the integrated machine to be calibrated 2000 in the rotation direction of the second output shaft 2200. Thus, the integrated machine to be calibrated 2000 can be clamped and fixed by the two second pressure heads 540, so that the integrated machine to be calibrated 2000 is fixed relative to the base 100.

[0106] The calibration device 1000 provided in this application can be adapted to different integrated machines 2000 to be calibrated, which has higher versatility and is easy to operate.
