[0022] See also Figures 1 to 5 , the figure shows the preferred structure of the automatic marking device in this embodiment. As shown in the figure, the automatic marking device includes: a platform 1, a support frame 2, a clamping mechanism 3, a bottom plate 4 and at least two support bodies 5. Among them, the platform 1 can be a plate-shaped body or other shapes, but as long as its top surface is flat, so as to facilitate the arrangement of other components, this embodiment does not impose any restrictions on the structure of the platform 1.

[0023] The bottom of the support frame 2 ( Figure 2 The lower part (shown in the figure) is adjustably arranged on the platform 1 so that the position of the support frame 2 on the platform 1 can be adjusted. The clamping mechanism 3 is rotatably arranged on the support frame 2, and the clamping mechanism 3 is used to clamp the first marking piece and drive the first marking piece to rotate. Specifically, according to the size of the first marking piece, the position of the support frame 2 on the platform 1 is adjusted to facilitate the clamping mechanism 3 to clamp the first marking piece. After the clamping mechanism 3 clamps, the clamping mechanism 3 can rotate relative to the support frame 2, thereby driving the first marking piece to rotate, so that the first marking piece can rotate one circle. The marking machine marks the first marking piece, and the first marking piece can be a component such as a pipe.

[0024] The bottom plate 4 is detachably arranged on the top of the support frame 2 ( Figure 2 The bottom plate 4 is used to place the second marking part. The second marking part can be a plate or other component, and the second marking part is placed on the bottom plate 4, and the marking machine marks the second marking part. Specifically, the detachable connection between the bottom plate 4 and the support frame 2 can be a bolt connection, etc., and this embodiment does not impose any restrictions on this.

[0025] Each support body 5 is detachably disposed on the bottom plate 4, and each support body 5 is disposed at intervals, and each support body 5 is used to support the third marking piece. Specifically, the bottom plate 4 is provided with a plurality of plug holes 41, each plug hole 41 is disposed at intervals, and each plug hole 41 is disposed along the length direction of the bottom plate 4 ( Figure 3 The bottom of each support body 5 ( Figure 2 The lower part shown in the figure) is inserted into one of the insertion holes 41, and the top ( Figure 2 The upper part shown in the figure is provided with a V-shaped receiving groove 13, which can carry the third marking part. After the third marking part is placed in the receiving groove 13 of each support body 5, the marking machine marks the third marking part, which can be a component such as a rod.

[0026] In specific implementation, the number of the support bodies 5 and the number of the plug holes 41 can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. Each support body 5 can be inserted into adjacent plug holes 41 in sequence, or can be inserted into the plug holes 41 at intervals, and this embodiment does not impose any restrictions on this.

[0027] In specific implementation, when marking the pipe, the position of the support frame 2 on the platform 1 is adjusted, the clamping mechanism 3 clamps the pipe, and the rotation of the clamping mechanism 3 relative to the support frame 2 drives the rotation of the pipe, and the marking machine marks the pipe.

[0028] When marking the plate, the bottom plate 4 is arranged on the top of the support frame 2, the plate is placed on the bottom plate 4, and the marking machine marks the plate.

[0029] When marking the rod, a plurality of supports 5 are arranged on the bottom plate 4, and the rod is placed on each of the supports 5, and the marking machine marks the rod.

[0030] It can be seen that in this embodiment, the position of the support frame 2 on the platform 1 is adjustable to adapt to the size of the first marking piece. The clamping mechanism 3 clamps the first marking piece and can rotate relative to the support frame 2. The clamping mechanism 3 can drive the first marking piece to rotate, so that the first marking piece can rotate one circle in situ. There is no need to manually rotate the first marking piece, thereby ensuring accurate and stable marking. The base plate 4 can be used to place the second marking piece. Each support body 5 can support the third marking piece after being detachably connected to the base plate 4. In this way, the device can realize marking of the first marking piece, the second marking piece and the third marking piece, thereby expanding the scope of use, so that the device can mark a variety of different types of marking pieces, and install and remove the base plate 4 and each support body 5 according to the types of the first marking piece, the second marking piece and the third marking piece, thereby ensuring stable marking. This solves the problem in the prior art that the piece to be marked is placed on a flat plate for marking and cannot be rotated in situ during pipe marking, resulting in unstable marking.

[0031] See also Figures 1 to 5 In the above embodiment, the support frame 2 may include: a first support plate 21 and a second support plate 22. The first support plate 21 and the second support plate 22 are arranged side by side and spaced a certain distance apart. The bottom of the first support plate 21 ( Figure 2 The lower part shown in FIG. 1 ) and the bottom of the second support plate 22 ( Figure 2 The lower part shown in the figure) are both adjustably arranged on the platform 1, that is, the positions of the first support plate 21 and the second support plate 22 on the platform 1 are adjustable, that is, the distance between the first support plate 21 and the second support plate 22 is adjusted to adapt to the outer diameter of the first marking part.

[0032] The bottom plate 4 is detachably disposed on the top of the first support plate 21 ( Figure 2The upper part shown in FIG. 1 and the top of the second support plate 22 ( Figure 2 Specifically, the bottom plate 4 is horizontally arranged between the top of the first support plate 21 and the top of the second support plate 22, and the bottom plate 4 is detachably connected to the top of the first support plate 21 and the top of the second support plate 22, so that the first support plate 21 and the second support plate 22 support and fix the bottom plate 4.

[0033] The clamping mechanism 3 is rotatably disposed between the first support plate 21 and the second support plate 22. The distance between the first support plate 21 and the second support plate 22 is first adjusted according to the outer diameter of the first marking piece, and then the first marking piece is clamped by the clamping mechanism 3 to ensure that the first marking piece can be stably clamped.

[0034] The clamping mechanism 3 may include: a first ejector pin 31, a second ejector pin 32, a pull rod 33 and an elastic member 34. The first ejector pin 31 and the second ejector pin 32 are both disposed between the first support plate 21 and the second support plate 22. One end of the first ejector pin 31 is a needle-like tip, and the other end is a plane. Correspondingly, one end of the second ejector pin 32 is also a needle-like tip, and the other end is a plane. The tip of the first ejector pin 31 is disposed opposite to the tip of the second ejector pin 32, and there is a preset gap between the tip of the first ejector pin 31 and the tip of the second ejector pin 32, and the gap is used to accommodate and clamp the first marking part, and the first marking part is clamped by the tip of the first ejector pin 31 and the tip of the second ejector pin 32.

[0035] The end of the first ejector pin 31 away from the tip is rotatably disposed on the first support plate 21, so that the first ejector pin 31 can rotate relative to the first support plate 21. The end of the second ejector pin 32 away from the tip is connected to the first end ( Figure 4 The second ejector pin 32 can rotate relative to the pull rod 33. The pull rod 33 is movably arranged on the second support plate 22, and the second end (left end) of the pull rod 33 is rotatably connected to the second ejector pin 32. Figure 4 The right end as shown in the figure is placed outside the second support plate 22, and the pull rod 33 can move freely relative to the second support plate 22 in a direction perpendicular to the second support plate 22.

[0036] Preferably, a fixing member 36 is provided on the outside of the second support plate 22, and the pull rod 33 is movably provided on the second support plate 22, and the pull rod 33 is movably connected to the fixing member 36. Specifically, the fixing member 36 is provided with a penetration hole, and after the pull rod 33 is penetrated through the second support plate 22, the pull rod 33 is placed in the penetration hole of the fixing member 36, and the pull rod 33 is movably connected to the fixing member 36, so that the pull rod 33 can move relative to the second support plate 22 and the fixing member 36, and the first end of the pull rod 33 is between the first support plate 21 and the second support plate 22 (relative to Figure 4The second ejector pin 32 moves left and right.

[0037] The elastic member 34 is sleeved on the pull rod 33 , and the elastic member 34 is placed between the second ejector pin 32 and the second support plate 22 .

[0038] When in use, first, according to the outer diameter of the first marking piece, adjust the positions of the first support plate 21 and the second support plate 22 on the platform 1, that is, adjust the distance between the first support plate 21 and the second support plate 22 so that the distance is slightly smaller than the outer diameter of the first marking piece. Then, place the first marking piece between the tip of the first ejector pin 31 and the tip of the second ejector pin 32. Since the distance between the first support plate 21 and the second support plate 22 is slightly smaller than the outer diameter of the first marking piece, when the first marking piece is clamped, the first marking piece squeezes the tip of the second ejector pin 32, so that the second ejector pin 32 drives the pull rod 33 to move toward the outside of the second support plate 22. When moving, the second ejector pin 32 squeezes the elastic member 34, so that the elastic member 34 is in a compressed state. By utilizing the elastic force of the elastic member 34, the tip of the first ejector pin 31 and the tip of the second ejector pin 32 can stably clamp the first marking piece to prevent the first marking piece from falling. When the first ejector pin 31 rotates relative to the first support plate 21, the rotation of the first ejector pin 31 drives the first marking part to rotate. Since the second ejector pin 32 can rotate relative to the pull rod 33, the rotation of the first marking part drives the second ejector pin 32 to rotate. In this way, the first marking part can freely rotate one circle in place between the first ejector pin 31 and the second ejector pin 32, and the marking machine can mark the first marking part. After the marking is completed and the first marking part is removed, the elastic member 34 can drive the second ejector pin 32 to move toward the first support plate 21 under the action of the elastic restoring force so as to restore to the initial state.

[0039] It can be seen that in this embodiment, the spacing between the first support plate 21 and the second support plate 22 is adjusted according to the outer diameter of the first marking piece, and the first marking piece is clamped between the tip of the first ejector pin 31 and the tip of the second ejector pin 32. The first marking piece squeezes the second ejector pin 32, so that the pull rod 33 moves relative to the second support plate 22, and the elastic member 34 is compressed. Then, the first marking piece is clamped under the action of the elastic force of the elastic member 34 to prevent the first marking piece from falling. The rotation of the first ejector pin 31 can drive the first marking piece to rotate in situ, so that the marking machine can stably and accurately mark the first marking piece.

[0040] See also Figures 1 to 5In the above embodiment, the automatic marking device may further include: a driving mechanism 35. A connecting rod 15 is provided at one end of the first ejector pin 31 away from the tip, and the connecting rod 15 is rotatably arranged in the first support plate 21, and the end of the connecting rod 15 is placed outside the first support plate 21. The driving mechanism 35 is connected to the end of the connecting rod 15 placed outside the first support plate 21, and the driving mechanism 35 is used to drive the connecting rod 15 to rotate, thereby driving the first ejector pin 31 to rotate.

[0041] Specifically, the first ejector pin 31 is connected to the first end ( Figure 4 The connecting rod 15 is rotatably connected to the first support plate 21, and the second end ( Figure 4 The left end (as shown) is placed outside the first support plate 21 and connected to the driving mechanism 35.

[0042] In specific implementation, a through hole is opened in the first support plate 21 corresponding to the connecting rod 15, and a bearing 6 is arranged in the through hole. The outer ring of the bearing 6 is connected to the inner wall of the through hole of the first support plate 21, and the inner ring of the bearing 6 is for the connecting rod 15 to pass through and is connected to the connecting rod 15. Moreover, the outer ring of the bearing 6 does not rotate, but the inner ring rotates, so that the connecting rod 15 can rotate relative to the first support plate 21.

[0043] In a specific implementation, the driving mechanism 35 may include: a driving motor 351 and a coupling 352. The driving motor 351 is connected to the coupling 352, and the coupling 352 is connected to the second end of the connecting rod 15. The driving motor 351 and the coupling 352 can be supported by the third support plate 23. The bottom of the third support plate 23 ( Figure 4 The lower part shown in FIG. 1 can be connected to the platform 1 in an adjustable manner, and the top of the third support plate 23 ( Figure 4 The upper portion shown in FIG. 1 is detachably connected to the bottom plate 4. The third support plate 23 is parallel to the first support plate 21.

[0044] It can be seen that in this embodiment, the driving mechanism 35 drives the connecting rod 15 to rotate. Since the connecting rod 15 is connected to the first ejector pin 31, the rotation of the connecting rod 15 drives the first ejector pin 31 to rotate, and then drives the first marking part to rotate. There is no need to manually drive the first ejector pin 31 to rotate, thereby realizing automatic drive.

[0045] See also Figures 1 to 5 In the above embodiment, a groove is provided at one end of the second ejector pin 32 away from the tip, and the pull rod 33 is rotatably inserted into the groove. Specifically, a bearing 6 may be provided in the groove, the outer ring of the bearing 6 is connected to the inner wall of the groove, the inner ring of the bearing 6 is connected to the pull rod 33, and the inner ring of the bearing 6 does not rotate, but the outer ring rotates, so that the second ejector pin 32 can rotate relative to the pull rod 33.

[0046] An annular retaining ring 7 is arranged near the second ejector pin 32 of the pull rod 33, a thrust ball bearing 8 is arranged between the retaining ring 7 and the end of the second ejector pin 32 away from the tip, and the elastic member 34 is placed between the retaining ring 7 and the second support plate 22. Specifically, the retaining ring 7 and the pull rod 33 are fixedly connected, and the retaining ring 7 is arranged near the second ejector pin 32. The provision of the thrust ball bearing 8 can reduce friction, ensure that the second ejector pin 32 and the pull rod 33 can rotate freely, and further ensure that the first marking part can rotate freely between the first ejector pin 31 and the second ejector pin 32.

[0047] See also Figures 1 to 5 In the above embodiments, the automatic marking device may further include: a guide rail 9, a scale 10, two bases 11 and two locking mechanisms 12. The guide rail 9 and the scale 10 are both arranged on the platform 1, and the scale 10 is arranged in parallel with the guide rail 9. Specifically, the platform 1 may be rectangular, and the guide rail 9 and the scale 10 are both arranged along the length direction of the platform 1 ( Figure 3 The direction from left to right as shown) extends.

[0048] Both bases 11 are slidably disposed on the guide rail 9, that is, the two bases 11 can slide along the guide rail 9. The first support plate 21 and the second support plate 22 are disposed on the two bases 11 in a one-to-one correspondence, that is, the first support plate 21 is disposed on one of the bases 11, and the second support plate 22 is disposed on the other base 11. The sliding of the two bases 11 along the guide rail 9 drives the adjustment of the positions of the first support plate 21 and the second support plate 22 on the platform 1.

[0049] In a specific implementation, the third support plate 23 is arranged in parallel with the first support plate 21 , and the third support plate 23 and the first support plate 21 are both arranged on the same base 11 .

[0050] The two locking mechanisms 12 correspond to the two bases 11 one by one. Each locking mechanism 12 is arranged between the platform 1 and the corresponding base 11. Each locking mechanism 12 is used to lock the corresponding base 11 so that the corresponding base 11 is relatively fixed to the platform 1, that is, the position of the first support plate 21 or the second support plate 22 on the platform 1 is fixed.

[0051] Each locking mechanism 12 may include: a positioning plate 121 and a locking bolt 122. The positioning plate 121 is detachably connected to the corresponding base 11, the positioning plate 121 is parallel to the platform 1, and there is a preset distance between the positioning plate 121 and the platform 1. The positioning plate 121 is provided with a bolt hole, and the locking bolt 122 is screwed into the bolt hole and abuts against the platform 1.

[0052] Specifically, the positioning plate 121 may be L-shaped, including: a horizontal plate and a vertical plate connected vertically; the horizontal plate is parallel to the platform 1 and has a certain spacing, the vertical plate is detachably connected to the corresponding base 11, and the horizontal plate is provided with a bolt hole. When the corresponding base 11 slides to the desired position along the guide rail 9, the locking bolt 122 is screwed into the bolt hole, and the end of the locking bolt 122 abuts against the platform 1, so that the positioning plate 121 is relatively locked with the platform 1, thereby ensuring that the corresponding base 11 is relatively locked with the platform 1, that is, the position of the first support plate 21 or the second support plate 22 on the platform 1 is determined to prevent the first support plate 21 or the second support plate 22 from sliding.

[0053] In a specific implementation, there are two guide rails 9, which are arranged in parallel and at a certain distance, and each base 11 is arranged horizontally between the two guide rails 9, so that each base 11 is slidably connected to the two guide rails 9. A slider 14 is provided at the bottom of each base 11, and the slider 14 is slidably connected to the corresponding guide rail 9.

[0054] It can be seen that in the present embodiment, the two bases 11 slide along the guide rails 9 to respectively drive the first support plate 21 and the second support plate 22 to slide, thereby facilitating the adjustment of the distance between the two to adapt to the outer diameter of the first marking component, and each base 11 is locked by a corresponding locking mechanism 12 to lock the first support plate 21 or the second support plate 22. The setting of the scale 10 can adjust the position of the two bases 11 according to the outer diameter of the first marking component, that is, adjust the distance between the first support plate 21 and the second support plate 22, thereby ensuring the accuracy of the adjustment.

[0055] In summary, in this embodiment, the clamping mechanism 3 can drive the first marking piece to rotate, so that the first marking piece can rotate one circle in place without manually rotating the first marking piece, ensuring the accuracy and stability of the marking, and only by controlling the interval between two adjacent circles on the first marking piece, the interval between each adjacent circle can be ensured to be the same. The device can also realize marking of the first marking piece, the second marking piece and the third marking piece, expanding the scope of use, so that the device can mark a variety of different types of marking pieces, and install and remove the base plate 4 and each support body 5 according to the type of the first marking piece, the second marking piece and the third marking piece, to ensure the stability of the marking. In addition, the device can mark marking pieces of different lengths and ensure the symmetry and accuracy of the marking position.
