Description
Technical Field
[0001] The present application relates to the technical field of a holding mechanism, and in particular to a pipe clamping platform. Background Art
[0002] Laser tube cutting machine is a mechanical equipment that uses laser technology to cut metal or non-metallic tubes. Laser tube cutting machine has the advantages of high precision, high efficiency, and non-contact processing. It is suitable for cutting and processing various tubes, including round tubes, square tubes, oval tubes and other tubes of different shapes.
[0003] The laser cutting machine mainly includes a fixed chuck, a laser cutting head and a mobile chuck (or feeding chuck). The mobile chuck can push the pipe to the laser cutting head. The fixed chuck can clamp the pipe during the laser cutting process and drive the pipe to rotate, so that the fixed laser cutting head can perform laser cutting on the pipe. There is a certain distance between the mobile chuck and the fixed chuck. After the mobile chuck pushes the end of the pipe, the pipe is separated from the mobile chuck. At this time, after the laser cutting head cuts the pipe, it is difficult for the mobile chuck to continue pushing the remaining part of the pipe, so that tail material will be generated in the process of the mobile chuck transferring the pipe, resulting in material waste. Summary of the invention
[0004] In order to reduce the generation of tailings during the process of transferring pipes by a mobile chuck, the present application provides a pipe clamping platform.
[0005] The present application provides a pipe clamping platform, which adopts the following technical solution:
[0006] A pipe clamping platform comprises a housing and a driving component for driving the housing to move, the housing is provided with a clamping component, the clamping component comprises two clamping arms, the housing is provided with a transmission component for driving the two clamping arms to move closer or farther away, and a limited position seat is provided between the two clamping arms.
[0007] By adopting the above technical scheme, when the pipe needs to be cut by the laser pipe cutting machine, one end of the pipe is placed in the fixed chuck, and then the driving assembly is started. The driving assembly drives the housing to move until the pipe is located between the two clamping arms, and then the transmission assembly is started so that the two clamping arms clamp the pipe, and then the driving assembly is started again so that the housing moves away from the fixed chuck, so that the clamping assembly pulls the pipe to move, and after moving to the corresponding distance, the laser cutting head cuts the pipe. Compared with the prior art, the mobile chuck is used to push the pipe. The present application eliminates the use of the mobile chuck by pulling the pipe to move by the clamping assembly, and the mobile chuck is more expensive, thereby reducing the cost of the laser pipe cutting machine. At the same time, the present application pulls the pipe at the end of the fixed chuck close to the laser cutting head, thereby reducing the generation of tail materials in the process of the mobile chuck transferring the pipe.
[0008] A limit seat is set between the two clamping arms, and the width of the limit seat is consistent with the width of the pipe fitting. The two clamping arms are close to each other. When the side wall of the clamping arm fits against one side of the limit seat, the limit seat can reduce the situation where the two clamping arms are too close to each other, thereby reducing the situation where the two clamping arms are too close to each other and the pipe fitting is damaged.
[0009] Preferably, the clamping arm includes a fixed rod, a connecting rod and a mounting rod, the fixed rod is arranged at one end of the transmission assembly, one end of the connecting rod is connected to one end of the fixed rod, the connecting rod is inclined, and the inclination direction of the connecting rod is inclined outward from top to bottom, one end of the mounting rod is installed on the connecting rod away from one end of the fixed rod, and the horizontal plane where the bottom surface of the fixed rod is located is higher than the horizontal plane of the top surface of the mounting rod.
[0010] By adopting the above technical solution, there is a height difference between the fixing rod and the installation rod, and the horizontal plane where the bottom surface of the fixing rod is located is higher than the horizontal plane of the top surface of the installation rod, so that the pipe fittings can pass through the bottom of the connecting rod and the fixing rod, thereby providing more placement space for the pipe fittings, making it more convenient to pull the pipe fittings.
[0011] Preferably, the clamping assembly further comprises a clamping block group, the clamping block group comprises two clamping blocks, the two clamping blocks are respectively arranged on the inner side of the mounting rod close thereto, and the two clamping blocks are arranged opposite to each other.
[0012] By adopting the above technical solution, the two clamping blocks are close to clamp the pipe fittings. Under the action of the clamping blocks, the pipe fittings can be clamped better, reducing the situation where the pipe fittings slip or move due to insecure clamping.
[0013] Preferably, a transverse groove is provided on the outer wall of the clamping block, the transverse groove is arranged horizontally, and the transverse groove is located in the middle of the clamping block.
[0014] By adopting the above technical solution, under the action of the transverse groove, the outer wall of the pipe is clamped into the transverse groove, so that the two clamping blocks clamp the pipe more stably, thereby further reducing the situation where the pipe slips or moves between the two clamping blocks.
[0015] Preferably, the outer wall of the clamping block is provided with a longitudinal groove, the longitudinal groove is vertically arranged, there are a plurality of the longitudinal grooves, and the plurality of the longitudinal grooves are distributed along the wide side of the side wall of the clamping block.
[0016] By adopting the above technical solution, under the action of the longitudinal groove, compared with the case where the clamping block is smooth, the present application can increase the friction between the clamping block and the pipe fitting, thereby reducing the situation where the pipe fitting slips or moves between the two clamping blocks.
[0017] Preferably, a guide rail is installed between the two clamping arms, two ends of the bottom surface of the guide rail are slidably connected with sliding plates respectively, and the fixing rod is installed on the bottom surface of the sliding plate.
[0018] By adopting the above technical solution, the fixed rod is installed on the bottom surface of the sliding plate, and the sliding plate is slidably connected to the guide rail. By pushing the sliding plate, the movement of the sliding plate can drive the clamping arm to move. Under the action of the guide rail, the movement of the clamping arm can be made smoother, thereby reducing the shaking and instability of the clamping arm during the movement.
[0019] Preferably, the transmission assembly includes a telescopic driving member, and the output end of the telescopic driving member is connected to the sliding plate on the inner side.
[0020] By adopting the above technical solution, the telescopic driving member is connected to the sliding plate on the inner side. When the telescopic driving member is started, the sliding plate is pushed to move, thereby pushing the clamping arm at the bottom of the sliding plate to move, thereby bringing the two clamping arms closer together, thereby clamping the pipe between the two clamping arms.
[0021] Preferably, the transmission assembly also includes a second rack, a third rack and a gear shaft, one end of the second rack is mounted on the sliding plate on the inner side, the gear shaft is rotatably connected to the housing, the gear shaft is located at the end of the second rack away from the sliding plate, the outer wall of the gear shaft is meshed with one side of the second rack, one end of the third rack is connected to the sliding plate on the outer side, and the other end of the third rack is meshed with the outer wall of the gear shaft.
[0022] By adopting the above technical solution, when the sliding plate on the inner side moves outward, the clamping arm on the inner side is driven to move outward. At the same time, the sliding plate drives the second rack to move, so that the gear shaft rotates. The rotation of the gear shaft drives the third rack to move. The third rack drives the sliding plate on the outer side to move, and then drives the clamping arm on the outer side to move inward, so that the two clamping arms are close to each other, so that the two opposite clamping blocks clamp the pipe fitting. Correspondingly, when the telescopic cylinder pulls the pushing seat inward to move, the two clamping arms move away from each other, so that the two opposite clamping blocks loosen the pipe fitting. Compared with the situation where one clamping arm moves, the present application is that the two clamping arms move close to each other at the same time, so as to better clamp the pipe fitting.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. When a pipe needs to be cut using a laser pipe cutting machine, one end of the pipe is placed in a fixed chuck, and then the drive assembly is started. The drive assembly drives the housing to move until the pipe is between the two clamping arms, and then the transmission assembly is started so that the two clamping arms clamp the pipe, and then the drive assembly is started again to move the housing away from the fixed chuck, thereby causing the clamping assembly to pull the pipe to move. After moving to a corresponding distance, the laser cutting head cuts the pipe. Compared with the prior art, in which a mobile chuck is used to push the pipe, the present application eliminates the use of a mobile chuck by pulling the pipe to move using a clamping assembly, and the mobile chuck is more expensive, thereby reducing the cost of the laser pipe cutting machine. At the same time, the present application pulls the pipe at one end of the fixed chuck close to the laser cutting head, thereby reducing the generation of tail material during the process of the mobile chuck transferring the pipe.
[0025] 2. The two clamping blocks are brought close together to clamp the pipe fittings. Under the action of the clamping blocks, the pipe fittings can be clamped better, reducing the situation where the pipe fittings slip or move due to insecure clamping. BRIEF DESCRIPTION OF THE DRAWINGS

The extension direction of the first rack 31 is parallel to the long side of the frame 1. The first gear 32 is assembled with the output end of the motor. The outer wall of the first gear 32 is meshed with one side of the first rack 31. When the motor is started, the motor drives the first gear 32 to rotate, and under the cooperation of the first gear 32 and the first rack 31, the casing 2 is driven to move.
[0038] Reference Figure 4 and Figure 5A mounting plate 21 is fixed in the casing 2, a guide rail 22 is fixed on the bottom of the mounting plate 21, the extension direction of the guide rail 22 is parallel to the long side of the mounting plate 21, there are two guide rails 22, the two guide rails 22 are relatively parallel and arranged, a sliding plate 23 is slidably connected between the bottom surfaces of the two guide rails 22, the long side of the sliding plate 23 is perpendicular to the long side of the guide rail 22, there are two sliding plates 23, and the two sliding plates 23 are distributed at both ends of the guide rail 22.
[0039] The bottom surfaces of the two sliding plates 23 are respectively provided with a group of mounting holes 231, and the number of the groups of mounting holes 231 depends on the situation. In the embodiment of the present application, the number of the groups of mounting holes 231 on the bottom surface of a sliding plate 23 is two, and the two groups of mounting holes 231 are distributed along the wide side of the sliding plate 23.

[0041] Reference Figure 5 and Figure 6 The clamping assembly also includes a clamping block group 5, and the clamping block group 5 includes two clamping blocks 5. The two clamping blocks 5 are respectively fixed on the inner side of the mounting rod 43 close thereto, and the two clamping blocks 5 are arranged opposite to each other. The outer wall of the clamping block 5 is provided with a transverse groove 51, and the transverse groove 51 is arranged horizontally. The transverse groove 51 is located in the middle of the clamping block 5. The outer wall of the clamping block 5 is provided with a longitudinal groove 52, and the longitudinal groove 52 is arranged vertically. There are multiple longitudinal grooves 52, and the multiple longitudinal grooves 52 are distributed along the wide side of the side wall of the clamping block 5. The number of the clamping block group 5 depends on the specific situation. In the embodiment of the present application, there are two clamping blocks 5, and the two clamping blocks 5 are distributed along the long side of the mounting rod 43.
[0042] The pipe fitting is located between two opposing clamping blocks 5, and the two opposing clamping blocks 5 are close to each other, thereby clamping the pipe fitting. Under the action of the transverse groove 51, the outer wall of the pipe fitting is stuck into the transverse groove 51, so that the two clamping blocks 5 clamp the pipe fitting more stably.

[0043] Reference Figure 5 and Figure 7 A transmission assembly 6 is provided on the mounting plate 21, and the transmission assembly 6 includes a telescopic driving member, a second rack 62, a third rack 63 and a gear shaft 64. In the embodiment of the present application, the telescopic driving member is a telescopic cylinder 61, and the telescopic cylinder 61 is mounted on the top surface of the mounting plate 21. A pushing seat 65 is assembled at the output end of the telescopic cylinder 61, and the bottom of the pushing seat 65 is fixed to the top surface of the sliding plate 23 on the inner side. One end of the second rack 62 is fixed to the top surface of the sliding plate 23 on the inner side, and the top of the gear shaft 64 is rotatably connected to the mounting plate 21.

[0044] Start the telescopic cylinder 61. When the telescopic cylinder 61 pushes the pushing seat 65 outward to move, the pushing seat 65 pushes the sliding plate 23 to move, thereby driving the clamping arm 4 on the inner side to move outward. At the same time, the sliding plate 23 drives the second rack 62 to move, so that the gear shaft 64 rotates. The rotation of the gear shaft 64 drives the third rack 63 to move. The third rack 63 drives the sliding plate 23 on the outer side to move, and then drives the clamping arm 4 on the outer side to move inward, so that the two clamping arms 4 are close to each other, so that the two opposite clamping blocks 5 clamp the pipe fitting. Correspondingly, when the telescopic cylinder 61 pulls the pushing seat 65 inward to move, the two clamping arms 4 move away from each other, so that the two opposite clamping blocks 5 loosen the pipe fitting.
[0045] Reference Figure 1When the pipe needs to be cut using a laser pipe cutting machine, one end of the pipe is placed in the fixed chuck 8, and then the motor is started to drive the housing 2 to move until the pipe is located between the two opposite clamping blocks 5, and then the telescopic cylinder 61 is started so that the two clamping blocks 5 clamp the pipe, and then the motor is started again to move the housing 2 away from the fixed chuck 8, so that the clamping assembly pulls the pipe to move, and after moving to the corresponding distance, the laser cutting head 9 cuts the pipe. Compared with the prior art, in which a mobile chuck is used to push the pipe, the present application eliminates the use of a mobile chuck by pulling the pipe to move through the clamping assembly, and the mobile chuck is more expensive, thereby reducing the cost of the laser pipe cutting machine. At the same time, the present application pulls the pipe at the end of the fixed chuck 8 close to the laser cutting head 9, thereby reducing the generation of tailings during the process of the mobile chuck transferring the pipe.
[0046] Reference Figure 5 and Figure 7 The middle parts of the two guide rails 22 are respectively fixed with limit seats 7 by bolts. The width of the limit seats 7 is consistent with the width of the pipe fittings. The two clamping arms 4 are close to each other. When the side wall of the clamping arm 4 fits with one side of the limit seat 7, under the action of the limit seat 7, the situation where the two clamping arms 4 are too close to each other can be reduced, thereby reducing the situation where the two clamping arms 4 are too close to each other and cause the pipe fittings to be clamped and damaged. The connection between the limit seat 7 and the guide rail 22 is a detachable connection, so that the limit seats 7 of different widths can be replaced according to the width of the pipe.
