Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present utility model, numerous technical details have been set forth in order to provide a better understanding of the present utility model. However, the technical solutions claimed in the claims of the present utility model can be realized without these technical details and various changes and modifications based on the following embodiments.
The present utility model provides a pipe clamping mechanism, as shown in fig. 1, the pipe clamping mechanism 1 comprises: a first clamping arm 11, a second clamping arm 12, the second clamping arm 12 being disposed opposite the first clamping arm 11, and the second clamping arm 12 being rotatable relative to the first clamping arm 11 about a predetermined axis as a pivot axis. Wherein the first clamping arm 11 has a first head 111, the first tail 112 opposite to the first head 111, and a first clamping member 113 provided to the first head 111. The second clamping arm 12 has a second head 121, a second tail 122 opposite the second head 121, and a second clamping member 123 disposed on the second head 121. The first clamping member 113 and the second clamping member 123 are disposed opposite to each other, and when the second clamping arm 12 is rotated relative to the first clamping arm 11, the second clamping member 123 can move relative to the first clamping member 113 such that the first clamping member 113 and the second clamping member 123 can clamp or unclamp the pipe 100.
In some embodiments, as shown in fig. 4, a first tooth structure is disposed on a side of the first clamping member 113 facing the second clamping member 123, and a side of the second clamping member 123 facing the first clamping member 113 is a planar structure. In other embodiments, as shown in fig. 3, a side of the second clamping member 123 facing the first clamping member 113 is provided with a second tooth structure, and a side of the first clamping member 113 facing the second clamping member 123 is provided with a planar structure. In other embodiments, as shown in fig. 2, a first tooth structure is disposed on a side of the first clamping member 113 facing the second clamping member 123, and a second tooth structure is disposed on a side of the second clamping member 123 facing the first clamping member 113, where the first tooth structure is exactly engaged with the second tooth structure when in a clamped state.
Therefore, when the first clamping member 113 and the second clamping member 123 clamp the pipe 100, the clamping force on the pipe 100 can be improved by the first tooth structure and/or the second tooth structure, so that the sealing performance of the pipe 100 during inflation can be ensured, the air leakage phenomenon of the pipe 100 during inflation can be avoided, and the uniformity of the inner diameter dimension of the pipe 100 during the forming process can be improved.
Specifically, as shown in connection with fig. 2 to 4, the first tooth structure includes: a first tooth row 114 provided on the first head 111; and/or, the second tooth structure comprises: a second row of teeth 124 provided on the second head 121. In the clamped state, the extension direction of the first tooth row 114 and the second tooth row 124 is at an angle or perpendicular to the extension direction of the tube 100. And, when the second head 121 moves to a first preset position toward the first head 111, the first tooth row 114 may clamp the pipe 100 in cooperation with the second tooth row 124. When the second head 121 moves to a second predetermined position in a direction away from the first head 111, the first tooth row 114 may engage the second tooth row 124 to release the pipe 100, so that it is not difficult to find that a sufficient clamping force may be provided to the pipe 100 when the first clamping member 113 and the second clamping member 123 clamp the pipe 100 by the first tooth row 114 and the second tooth row 124, thereby ensuring sealing performance of the pipe 100.
Further, in some embodiments, as shown in connection with fig. 2, 3, and 4, the first dentition 114 includes: a plurality of first latches 1141 disposed on a side of the first clamping member 113 opposite to the second clamping member 123. Next, the second tooth row 124 includes: and a plurality of second latches 1241 disposed at one side of the second clamping member 123 opposite to the first clamping member 113. The first tooth grooves 1142 capable of being snapped into the second tooth grooves 1241 are formed between every two adjacent first tooth grooves 1141, and the second tooth grooves 1242 capable of being snapped into the first tooth grooves 1141 are formed between every two adjacent second tooth grooves 1241. Therefore, when the second head 121 moves toward the first head 111 to the first preset position, the first tooth row 114 and the second tooth row 124 may be engaged with each other, thereby achieving clamping of the pipe 100, and the clamping force of the pipe 100 may be increased by means of the engagement of the first tooth row 114 and the second tooth row 124, thereby ensuring sealing performance when the pipe 100 is inflated, and avoiding the occurrence of air leakage phenomenon of the pipe 100. In addition, in some embodiments, each of the first latches 1141 may be formed by protruding a portion of a side of the first clamping member 113 opposite to the second clamping member 123 in a direction toward the second clamping member 123. Also, the second latch 1241 may be a portion of a side of the second clamping member 123 opposite to the first clamping member 113, and may be formed to protrude toward the first clamping member 113.
Also, it should be noted that, in some embodiments, the end of the first latch 1141 away from the first clamping member 113 and/or the end of the second latch 1241 away from the second clamping member 123 are pointed, so that when each of the first latch 1141 of the first tooth row 114 and each of the second latch 1241 of the second tooth row 124 clamps the pipe 100, the clamping force of the pipe 100 can be increased, so that the pipe 100 can be firmly clamped, and when the pipe 100 is clamped by the first tooth row 114 and the second tooth row 124, the clamped portion of the pipe 100 can be deformed under the action of the pointed ends of the first latch 1241 and the pointed ends of the second latch 1242, thereby ensuring the sealing performance of the clamped portion of the pipe 100.
Of course, alternatively, in some embodiments, as shown in fig. 2, 3 and 4, each of the first latches 1141 of the first tooth row 114 is away from an end of the first clamping member 113, and/or each of the second latches 1241 of the second tooth row 124 is an arc surface, which is away from an end of the second clamping member 123, so as to ensure sealing performance of the pipe 100 when the first tooth row 114 and the second tooth row 124 clamp the pipe 100. Meanwhile, the cambered surfaces can also increase the clamping area of each first latch 1141 of the first tooth row 114 and each second latch 1241 of the second tooth row 124 when clamping the pipe 100, so that the stress generated when clamping the pipe 100 can be reduced, and the phenomenon that the pipe 100 is broken by clamping is avoided.
In addition, in order to achieve the rotation of the second clamping arm 12 relative to the first clamping arm 11, in some embodiments, as shown in fig. 1, the second clamping arm 12 further includes a positioning protrusion 125 located between the second head 121 and the second tail 122, for example, the positioning protrusion 125 may be formed by extending the second clamping arm 12 toward the first clamping arm 11, while the positioning protrusion 125 is further rotatably connected with the first clamping arm 11 through a hinge 13, and the hinge 13 may be a pivot axis of rotation of the second clamping arm 12 relative to the first clamping arm 11, such that the second clamping arm 12 may rotate relative to the first clamping arm 11 with the hinge 13 as a pivot axis.
Further, it should be noted that in other embodiments, the first clamping member 113 is connected to the first head 111 of the first clamping arm 11, and the second clamping member 123 is connected to the second head 121 of the second clamping arm 12, as shown in fig. 1, the first clamping member 113 is detachably disposed on the first head 111 of the first clamping arm 11, and the second clamping member 123 is detachably disposed on the second head 121 of the second clamping arm 12. For example, the first clamping member 113 and the first head 111 of the first clamping arm 11, the second clamping member 123 and the second head 121 of the second clamping arm 12 may be connected by screws, or the first clamping member 113 and the first head 111 of the first clamping arm 11, and the second clamping member 123 and the second head 121 of the second clamping arm 12 may be connected by clamping.
Finally, in some embodiments, as shown in fig. 1, the pipe clamping mechanism 1 further comprises: the driving device 14, and the driving device 14 is further used for driving the second clamping arm 12 to rotate relative to the first clamping arm 11, so that it is easy to see that the first clamping member 113 and the second clamping member 123 can clamp and unclamp the pipe 100 by driving the second clamping arm 12 by the driving device 14.
Also, as shown in fig. 1 and 5, the driving device 14 includes: a driving element 141 and an elastic element 142. The driving element 141 is disposed at the first tail 112 of the first clamping arm 11 and is fixedly connected with the first tail 112, meanwhile, the driving device 14 further includes a telescopic component 143, the telescopic component 143 is opposite to the first tail 112 and is fixedly connected with the driving element 141, and one end of the telescopic component 143 is abutted with the second tail 122 of the second clamping arm 12 and is telescopic towards the second tail 122 of the second clamping arm 12. Next, one end of the elastic member 141 is connected to the first tail portion 112 of the first clamping arm 11, and the other end of the elastic member 141 is connected to the second tail portion 122 of the second clamping arm 12. Also, it should be noted that in some embodiments, the elastic element 141 may be a spring, and of course, other components may be used for the elastic element 141 when applied.
It is thus readily apparent that when the driving element 141 drives the telescopic part 143 to extend in the direction of the second tail 122 of the second clamping arm 12, as shown in fig. 1, the telescopic part 143 can drive the second clamping arm 12 to rotate, so that the second clamping member 123 can move in the direction of the first clamping member 113, and the first clamping member 113 is immobilized, so that the second clamping member 123 can clamp the pipe 100 in cooperation with the first clamping member 113. When the driving element 141 drives the telescopic part 143 to retract in a direction away from the second tail 122 of the second clamping arm 12, as shown in fig. 1 and 5, when the telescopic part 143 abuts against the second tail 122 of the second clamping arm 12, the telescopic part 143 can be driven by the elastic force of the elastic element 141 to rotate reversely during retraction, so that the second clamping member 123 can also move in a direction away from the first clamping member 113, and the second clamping member 123 can cooperate with the first clamping member 113 to release the pipe 100.
Specifically, in some embodiments, as shown in fig. 1, the driving element 141 may be a cylinder, a hydraulic cylinder, or a motor. When the driving element 141 is a cylinder or a hydraulic cylinder, the telescopic member 143 is a piston rod of the cylinder or the hydraulic cylinder, and the second clamp arm 12 is driven to rotate with respect to the first clamp arm 11 by telescopic movement of the piston rod. When the driving element 141 is a motor, the telescopic member 143 is screwed to a spindle of the motor, so that when the spindle of the motor rotates, the telescopic member 141 can be linearly moved in the axial direction of the spindle by the screwed connection of the spindle to the telescopic member 143, and the telescopic member 143 can drive the second clamp arm 12 to rotate relative to the first clamp arm 11.
The present utility model also provides a pipe manufacturing apparatus, as shown in fig. 6, comprising: the pipe clamping mechanism 1, the heating mechanism 2 and the inflating mechanism 3 as described above.
Wherein, in connection with fig. 6, the pipe clamping mechanism 1 is used for clamping the pipe 100. And, the heating mechanism 2 has a heating chamber through which the pipe 100 can pass, and the heating mechanism 2 is used for heating the pipe 100.
And, as shown in fig. 6, the inflation mechanism 3 is used for clamping the end of the pipe 100 and for inflating the inside of the pipe 100, and at the same time, the inflation mechanism 3 is movable in a direction approaching or moving away from the heating mechanism 2 and is used for pulling the pipe 100 to gradually extend in a direction moving away from the heating mechanism 2 when moving in a direction moving away from the clamping mechanism 1.
As can be seen from the above, since the clamping mechanism 1 comprises the first clamping arm 11 and the second clamping arm 12, and the first head 111 of the first clamping arm 11 is provided with the first clamping member 113, and the second head 121 of the second clamping arm 12 is provided with the second clamping member 123, at the same time, when the second clamping arm 11 rotates relative to the first clamping arm 12, the first head 111 can move relative to the second head 121, so that the first clamping member 113 and the second clamping member 123 can clamp the pipe 100. In addition, the first clamping member 113 is provided with a first tooth-shaped structure with respect to one side of the second clamping member 123, and/or the second clamping member 123 is provided with a second tooth-shaped structure with respect to one side of the first clamping member 113, so that when the first clamping member 113 and the second clamping member 123 clamp the pipe 100, the clamping force on the pipe 100 can be improved through the first tooth-shaped structure and the second tooth-shaped structure, thereby ensuring the sealing performance of the pipe 100 when the pipe 100 is inflated, avoiding the occurrence of air leakage phenomenon of the pipe 100 when the pipe 100 is inflated, and improving the uniformity of the inner diameter dimension of the pipe 100 in the forming process.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples of carrying out the utility model and that various changes in form and details may be made therein without departing from the spirit and scope of the utility model.
