Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1

[0027] Reference Figure 1 to Figure 4 , which is the first embodiment of the utility model, and this embodiment provides a pipe mouth trimming device for spiral steel pipe production. The pipe mouth trimming device for spiral steel pipe production includes a main body component 100 and an adjustment component 200. The two can cooperate to make the grinder and the clamp move toward each other at the same time to grind the steel pipe.

[0028] The main assembly 100 includes a knife sharpener 101 , a motor 102 and a pneumatic clamp 103 . The motor 102 is fixed to one side of the knife sharpener 101 , and the pneumatic clamp 103 is disposed on one side of the knife sharpener 101 .

[0029] When the steel pipe needs to be polished, the steel pipe is fixed by using the pneumatic clamp 103, and then the motor 102 is started. The motor 102 can drive the grinder 101 to rotate, and the rotating grinder 101 is brought into contact with the steel pipe so that the mouth of the steel pipe can be polished to keep the mouth of the steel pipe flat. The pneumatic clamp 103 belongs to the existing technology, so it will not be elaborated in detail.

[0030] The adjusting assembly 200 is disposed on the knife sharpener 101 , and includes an adjusting member 201 , a limiting member 202 and a driving member 203 . The adjusting member 201 is located on the knife sharpener 101 , the limiting member 202 is disposed on the adjusting member 201 , and the driving member 203 is located on the limiting member 202 .

[0031] When it is necessary to grind the steel pipe, the setting of the adjusting member 201 can move the sharpener 101 and the pneumatic clamp 103 towards each other at the same time to grind the steel pipe, thereby ensuring that the sharpener grinds the steel pipe mouth evenly, avoiding unevenness or uneven grinding, and improving the grinding effect.

When it is necessary to release the limit of the sharpener 101 and the pneumatic clamp 103, the setting of the driving member 203 can drive the limiting member 202 to move, thereby releasing the limit of the sharpener 101 and the pneumatic clamp 103.

[0032] Example 2

[0033] Reference Figure 1 to Figure 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0034] Specifically, the adjusting member 201 includes a first adjusting plate 201a, a second adjusting plate 201b and a supporting frame 201c.

The second adjusting plate 201b is fixed to one side of the pneumatic clamp 103. The supporting frame 201c is located at the bottom of the second adjusting plate 201b.

[0035] When the distance between the sharpener 101 and the pneumatic clamp 103 needs to be adjusted, the second adjustment plate 201b is moved. The second adjustment plate 201b can also drive the first adjustment plate 201a to move toward each other. The movement of the two toward each other can drive the sharpener 101 and the pneumatic clamp 103 to move toward each other, so that the distance between the two can be adjusted. The support frame 201c is used to support the first adjustment plate 201a and the second adjustment plate 201b to prevent the two from offsetting.

[0036] Specifically, the adjusting member 201 also includes a first rack 201d, a gear 201e and a second rack 201f. The first rack 201d is fixed to one side of the first adjusting plate 201a, the gear 201e is arranged on one side of the first rack 201d, the gear 201e and the first rack 201d are meshed, and the second rack 201f is fixed to one side of the second adjusting plate 201b.

[0037] When the second adjustment plate 201b is moved, the second adjustment plate 201b will drive the second rack 201f to move. The second rack 201f is located on one side of the gear 201e. The second rack 201f is meshed with the gear 201e. The movement of the second rack 201f will drive the gear 201e to rotate. The rotation of the gear 201e will drive the first rack 201d to move. At this time, the movement of the first rack 201d can drive the first adjustment plate 201a to move.

[0038] A sliding bar is respectively arranged at the top of the first rack 201d and the second rack 201f, and the top of the sliding bar is respectively fixed to the bottom of the first adjustment plate 201a and the second adjustment plate 201b, and a sliding groove is arranged at the top of the support frame 201c, and the sliding bar slides in the sliding groove, and when the first rack 201d and the second rack 201f move, the sliding bar will be driven to move, and the movement of the sliding bar can drive the first adjustment plate 201a and the second adjustment plate 201b to move.

[0039] Specifically, the adjusting member 201 further includes a pulley 201g and a sliding frame 201h. The pulley 201g is hinged at the bottom of the first adjusting plate 201a, and the sliding frame 201h is fixed to the inner wall of the supporting frame 201c.

[0040] There are two pulleys 201g, which are hinged to the bottom of the first adjustment plate 201a and the second adjustment plate 201b respectively. A movable groove is set on the top of the sliding frame 201h. The pulley 201g moves in the movable groove. The first adjustment plate 201a and the second adjustment plate 201b will drive the pulley 201g to move when moving. The pulley 201g will rotate in the movable groove when moving, thereby ensuring the smoothness of the first adjustment plate 201a and the second adjustment plate 201b when moving, and can support the two to prevent them from offsetting.

[0041] Specifically, the limiting member 202 includes a limiting plate 202a and a limiting block 202b. The limiting plate 202a is fixed to the top of the supporting frame 201c, and the limiting block 202b is located on the top of the limiting plate 202a.

[0042] A limiting groove corresponding to the limiting block 202b is provided on the top of the limiting plate 202a. When the grinding knife 101 and the pneumatic clamp 103 are moved to the specified spacing, they need to be fixed and then the steel pipe is ground. By engaging the limiting block 202b with the limiting groove, the spacing between the grinding knife 101 and the pneumatic clamp 103 can be fixed, thereby ensuring the stability of the steel pipe grinding. The limiting plate 202a is used to support the limiting block 202b to prevent the limiting block 202b from shifting.

[0043] Specifically, the limiting member 202 further includes a moving rod 202c and a supporting sleeve 202d, the moving rod 202c is fixed to the top of the limiting block 202b, the supporting sleeve 202d is sleeved on the outside of the moving rod 202c, and the supporting sleeve 202d and the moving rod 202c are movably connected.

[0044] When it is necessary to release the limit of the sharpening knife 101 and the pneumatic clamp 103, the moving rod 202c is moved. The movement of the moving rod 202c can drive the limit block 202b to separate from the limit groove, thereby releasing the limit of the sharpening knife 101 and the pneumatic clamp 103. The support sleeve 202d is used to support the moving rod 202c to prevent the moving rod 202c from deviating.

[0045] Specifically, the limiting member 202 further includes a spring 202e and a pressure plate 202f. The pressure plate 202f is sleeved on the outside of the moving rod 202c, and the spring 202e is fixed to one side of the pressure plate 202f.

[0046] When the moving rod 202c is moved, the pressure plate 202f will be driven to move. When the pressure plate 202f moves, it can apply a squeezing force to the spring 202e. The movement of the moving rod 202c can drive the limit block 202b to separate from the limit groove, thereby releasing the limit on the sharpener 101 and the pneumatic clamp 103. Then the moving rod 202c is released. At this time, the rebound force of the spring 202e can drive the limit block 202b to engage with the limit groove, thereby limiting the sharpener 101 and the pneumatic clamp 103 again.

[0047] Example 3

[0048] Reference Figure 3 and Figure 4 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0049] Specifically, the limiting member 202 further includes a positioning disk 202g and a positioning plate 202h. The positioning disk 202g is sleeved on the outside of the supporting sleeve 202d. One end of the positioning plate 202h is fixed to one side of the positioning disk 202g, and the other end is fixed to one side of the second adjustment plate 201b.

[0050] The positioning plate 202g is used to support the support sleeve 202d to prevent the support sleeve 202d from shifting, and the positioning plate 202h is used to support the positioning plate 202g to prevent the positioning plate 202g from shifting.

[0051] Specifically, the driving member 203 includes a driving bar 203a and a driving plate 203b. The driving bar 203a is plugged into one end of the moving rod 202c, and the driving plate 203b is hinged to one side of the driving bar 203a.

[0052] When the moving rod 202c needs to be moved, the driving plate 203b is moved. At this time, the movement of the driving plate 203b will drive the driving bar 203a to move, and the movement of the driving bar 203a will drive the moving rod 202c to move. The movement of the moving rod 202c can drive the limit block 202b to separate from the limit groove.

[0053] Specifically, the driving member 203 further includes a supporting block 203c and a pressing plate 203d. The supporting block 203c is hinged to one side of the driving plate 203b. The supporting block 203c is fixed to the top of the positioning plate 202h, and the pressing plate 203d is fixed to one end of the driving plate 203b.

[0054] The support block 203c is used to support the driving plate 203b to prevent the driving plate 203b from deflecting, and the setting of the pressing plate 203d facilitates the movement of the driving plate 203b.

[0055] During use, when it is necessary to grind the steel pipe, first place the steel pipe in the pneumatic clamp 103, then use the pneumatic clamp 103 to fix the steel pipe, and then adjust the distance between the grinder 101 and the pneumatic clamp 103. First, it is necessary to release the limit of the two. By pressing the pressure plate 203d, the pressure plate 203d will drive the driving plate 203b to move. The movement of the driving plate 203b will drive the driving bar 203a to move. The movement of the driving bar 203a will drive the moving rod 202c to move. When the moving rod 202c is moved, the pressure plate 202f will be driven to move. The pressure plate 202f can apply a squeezing force to the spring 202e when moving. The movement of the moving rod 202c can drive the limit block 202b to separate from the limit groove, thereby releasing the limit of the grinder 101 and the pneumatic clamp 103.

[0056] Then the second adjusting plate 201b is moved. When the second adjusting plate 201b is moved, the second adjusting plate 201b will drive the second rack 201f to move. When the first adjusting plate 201a and the second adjusting plate 201b move, they will drive the pulley 201g to move. When the pulley 201g moves, it will rotate in the moving groove, so as to ensure the smoothness of the first adjusting plate 201a and the second adjusting plate 201b when moving, and support the two to prevent them from offset. The movement of the second rack 201f will drive the gear 201e to rotate, and the rotation of the gear 201e will drive the first rack 201d to move. At this time, the movement of the first rack 201d can drive the first adjusting plate 201a to move, and the distance between the sharpening knife 101 and the pneumatic clamp 103 will be reduced.

[0057] After the sharpening knife 101 is moved to contact with the steel pipe, in order to prevent the sharpening knife 101 and the pneumatic clamp 103 from moving on their own, causing the distance between them to change, the pressure plate 203d is released. At this time, the rebound force of the spring 202e can drive the limit block 202b to engage with the limit groove, so that the sharpening knife 101 and the pneumatic clamp 103 can be limited. Then the motor 102 is started, and the motor 102 can drive the sharpening knife 101 to rotate. The steel pipe can be grinded by the rotation of the sharpening knife 101.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
