Description

Technical Field

[0001] The present application belongs to the technical field of pipe cutting machines, and specifically relates to a feeding support device for a pipe cutting machine. Background Art

[0002] Laser tube cutting machine is a high-precision equipment that uses laser technology to cut tubes. It has the characteristics of fast cutting speed and high precision, so it is widely used.

[0003] At present, the laser tube cutting machine includes a bed, a front chuck arranged at one end of the bed, a rear chuck arranged at the other end of the bed, and a cutting head arranged on the bed. The front chuck and the rear chuck are coaxially arranged, and the rear chuck can move along the length direction of the bed. In order to facilitate the loading of the laser tube cutting machine, it is usually necessary to equip the laser tube cutting machine with a loading device so that the loading device pushes the tube, and then the tube moves to the bottom of the front chuck and the rear chuck, and then the tube is lifted to make the tube coaxial with the front chuck and the rear chuck, and then the rear chuck moves and clamps the tube, and at the same time makes the tube pass through the front chuck until the position where the tube needs to be cut moves to the bottom of the cutting head.

[0004] However, there are two common ways to lift the pipe. One is to lift the pipe manually. Although this method reduces the cost of the equipment, it affects the cutting efficiency of the laser cutting machine. The other is to set multiple sets of lifting devices on the bed, and each set of lifting devices is driven by a corresponding driving member, which makes it easy for the multiple sets of lifting devices to have deviations in the movement stroke, thereby affecting the stability of the pipe lifting, so that the pipe cannot be coaxial with the front chuck and the rear chuck, thereby affecting the cutting efficiency of the pipe. Utility Model Content

[0005] The present application provides a feeding support device for a pipe cutting machine to improve the cutting efficiency of pipes.

[0006] The technical solution adopted in this application is:

[0007] A feeding support device for a pipe cutting machine includes a driving assembly and multiple lifting assemblies, each of which includes a support seat and a lifting arm arranged on the support seat, and the driving assembly includes a driving member arranged on one of the support seats and a linkage member connected to the driving member in a transmission manner, and the linkage member acts on the multiple lifting arms to make the multiple lifting arms move synchronously in the vertical direction.

[0008] By adopting the above-mentioned technical scheme, when using the feeding support device in the present application, it is installed between the pipe cutting machine and the feeding device, so that the feeding device pushes the pipe to the position of the lifting arm, and then the driving part drives the linkage part, thereby making the multiple lifting arms move synchronously under the action of the linkage part, so that the multiple lifting arms lift the pipe together. Since the multiple lifting arms move synchronously under the action of the linkage part, the situation of inconsistent movement strokes of the multiple lifting arms is avoided, thereby increasing the stability of lifting the pipe and avoiding the situation that the pipe may not be coaxial with the front chuck and the rear chuck, that is, the lifting effect of the pipe is improved, and then the cutting efficiency of the pipe is improved.

[0009] Optionally, the support seat is provided with a lifting seat, the lifting arm is arranged on the lifting seat, and the linkage is transmission-connected to the lifting seat.

[0010] By adopting the above technical solution, when lifting the pipe, the driving member drives the linkage member to move, the linkage member drives the lifting seat to move, and then the lifting seat drives the lifting arm to move, thereby shortening the length of the lifting arm, thereby ensuring the structural strength of the lifting arm, further increasing the stability of the pipe when lifting, and further improving the cutting efficiency of the pipe.

[0011] Optionally, the linkage member is provided with a transmission tooth, and the lifting seat is provided with a matching tooth meshing and transmission connected with the transmission tooth, and the matching tooth is extended in a vertical direction.

[0012] By adopting the above technical solution, when lifting the pipe, the output shaft of the driving member drives the linkage member to rotate, and the linkage member drives the transmission teeth to rotate, thereby causing the transmission teeth and the matching teeth to rotate relative to each other, and then the lifting seat rises under the action of the matching teeth, so that the lifting seat drives the lifting arm to move to achieve the lifting of the pipe. By setting the transmission teeth and the matching teeth, the transmission efficiency between the linkage member and the lifting seat is increased, thereby improving the lifting efficiency of the pipe and further improving the cutting efficiency of the pipe.

[0013] Optionally, the lifting arm has an articulated end hinged to the lifting seat and a lifting end swinging around the articulated end, and the lifting seat is provided with a power member for driving the lifting arm to rise or fall.

[0014] By adopting the above technical solution, when the rear chuck drives the pipe to move along the length direction of the bed, the lifting arm close to the rear chuck may interfere with the rear chuck relative to each other. At this time, the power part drives the lifting arm to make the lifting arm and the lifting seat rotate relative to each other, and then the lifting arm that interferes with the rear chuck falls down, so that the lifting arm close to the rear chuck avoids the rear chuck to ensure the normal movement of the rear chuck, and at the same time, the other lifting arms continue to support the pipe to increase the stability of the pipe and improve the cutting accuracy of the pipe cutting machine on the pipe.

[0015] Optionally, the support seat is provided with an auxiliary component, and the auxiliary component acts on the lifting seat and applies an upward pushing force to the lifting seat.

[0016] By adopting the above technical solution, when the lifting arm is driven upward, the auxiliary component applies an upward pushing force to the lifting seat to reduce the load of the driving component, thereby reducing the energy consumption of the driving component and increasing the service life of the driving component, thereby reducing the failure rate of the loading support device, thereby achieving the effect of increasing the service life of the loading support device.

[0017] Optionally, the support seat includes a fixed plate arranged on the bed, and the auxiliary component is arranged on the fixed plate.

[0018] By adopting the above technical solution, when the auxiliary part applies an upward pushing force to the lifting seat, the fixed plate supports the auxiliary part. Since the fixed plate is arranged on the bed, the stability of the auxiliary part is increased, and the pushing effect of the auxiliary part on the lifting seat is further guaranteed, which further reduces the workload of the driving part, thereby further reducing the failure rate of the feeding support device.

[0019] Optionally, one of the support seat and the lifting seat is provided with a slide rail, and the other of the two is provided with a slider that slidably cooperates with the slide rail.

[0020] By adopting the above technical solution, when the lifting seat and the support seat slide relative to each other, the slider and the slide rail slide relative to each other, so that the sliding cooperation between the slider and the slide rail guides the movement direction of the lifting seat, thereby increasing the stability of the lifting seat when moving in the vertical direction, and further increasing the stability when lifting the pipe.

[0021] Optionally, the lifting arm has a lifting end for lifting the pipe, the lifting end is rotatably connected to a roller, and the axial direction of the roller is arranged perpendicular to the length direction of the pipe.

[0022] By adopting the above technical solution, when the rear chuck drives the pipe to move along the length direction of the bed, the roller and the pipe roll relative to each other, so as to ensure the stability of the pipe while reducing the resistance of the rear chuck during movement, thereby reducing the workload of the driving structure of the rear chuck; in addition, it can also reduce the noise when the pipe and the lifting arm move relative to each other, thereby improving the customer's experience.

[0023] Optionally, the lifting end is provided with centering rollers located at both ends of the supporting rollers, and the lifting arm is provided with an actuator, and the actuator acts on the centering rollers to move the centering rollers in a direction of approaching or moving away from each other.

[0024] By adopting the above technical solution, after the lifting arm rises and contacts the pipe under the action of the driving member, the actuator is started, and the actuator drives the centering rollers, which then move in the direction of approaching each other and contact the pipe, so that the centering rollers adjust the pipe to make the central axis of the pipe coplanar with the central axis of the front chuck and the rear chuck, and then the driving member continues to drive the lifting arm until the central axis of the pipe is colinear with the central axis of the front chuck and the rear chuck. During this process, no staff participation is required, thereby further avoiding the need for manual adjustment of the pipe, thereby increasing the degree of automation when lifting the pipe, and further improving the cutting efficiency of the pipe.

[0025] Optionally, the support seat includes a first support plate and a second support plate arranged opposite to the first support plate, the lifting arm is located between the first support plate and the second support plate, and the first support plate and the second support plate are both arranged on the bed.

[0026] By adopting the above technical solution, the first support plate and the second support plate are both arranged on the bed, which can increase the connection stability between the support seat and the bed, and at the same time ensure the stability of the feeding support device, thereby ensuring the stability of lifting the pipe, and then ensuring the cutting efficiency of the pipe.

[0049] When using the feeding support device in the present application, it is installed between the pipe cutting machine and the feeding device so that the feeding device pushes the pipe to the position of the lifting arm 2, and then the driving member 3 drives the linkage member 4, so that the multiple lifting arms 2 move synchronously under the action of the linkage member 4, so that the multiple lifting arms 2 lift the pipe together. Since the multiple lifting arms 2 move synchronously under the action of the linkage member 4, the situation of inconsistent movement strokes of the multiple lifting arms 2 is avoided, thereby increasing the stability of lifting the pipe and avoiding the situation that the pipe may not be coaxial with the front chuck and the rear chuck, that is, the lifting effect of the pipe is improved, and then the cutting efficiency of the pipe is improved.

[0050] The present application does not specifically limit the number of lifting components. Preferably, refer to Figure 1 and Figure 2 The lifting components are arranged in multiple groups in sequence along the length direction of the bed 6 to further increase the stability of the pipe lifting and increase the lifting points of the pipe to further improve the cutting efficiency of the pipe.

[0051] Preferably, refer to Figures 1 to 4 The driving member 3 is a servo motor arranged on one of the support seats 1, and the linkage member 4 is a linkage shaft drivingly connected to the output shaft of the servo motor to improve the driving efficiency of the lifting arm 2, thereby improving the cutting efficiency of the pipe.

[0052] Preferably, the driving member 3 is arranged on a supporting base 1 located at the end of the bed 6, and multiple linkage shafts are provided. The multiple linkage shafts are coaxially arranged, and two adjacent linkage shafts are connected by a coupling 41 to reduce the torsional force exerted on a single linkage shaft, thereby ensuring the service life of the linkage shaft and reducing the failure rate of the feeding support device.

[0053] In a preferred embodiment, referring to Figure 3 and Figure 4 The support seat 1 is provided with a lifting seat 5, the lifting arm 2 is arranged on the lifting seat 5, and the linkage member 4 is transmission-connected with the lifting seat 5.

[0054] When lifting the pipe, the driving member 3 drives the linkage member 4 to move, the linkage member 4 drives the lifting seat 5 to move, and then the lifting seat 5 drives the lifting arm 2 to move. Through the setting of the lifting seat 5, the length of the lifting arm 2 is shortened, thereby ensuring the structural strength of the lifting arm 2, further increasing the stability when lifting the pipe, and further improving the cutting efficiency of the pipe.

[0055] In a preferred embodiment, referring to Figure 3 and Figure 4 The linkage member 4 is provided with a transmission tooth 42, and the lifting seat 5 is provided with a matching tooth 51 meshing and transmission-connected with the transmission tooth 42, and the matching tooth 51 is extended in the vertical direction.

The length direction of the rack is arranged in the vertical direction. Then, when the pipe is lifted, the output shaft of the driving member 3 drives the linkage member 4 to rotate, and the linkage member 4 drives the transmission tooth 42 to rotate, so that the gear and the rack rotate relative to each other, so that the lifting seat 5 rises under the cooperation of the gear and the rack, so that the lifting seat 5 drives the lifting arm 2 to rise to realize the lifting of the pipe. Through the arrangement of the gear and the rack, the transmission efficiency between the linkage member 4 and the lifting seat 5 is increased, thereby improving the lifting efficiency of the pipe, and further improving the cutting efficiency of the pipe.

[0060] When the rear chuck drives the pipe to move along the length direction of the bed 6, the lifting arm 2 close to the rear chuck may interfere with the rear chuck. At this time, the power part 52 drives the lifting arm 2 to make the lifting arm 2 and the lifting seat 5 rotate relative to each other, and then the lifting arm 2 that interferes with the rear chuck falls down, so that the lifting arm 2 close to the rear chuck forms a avoidance with the rear chuck to ensure the normal movement of the rear chuck, and at the same time, the other lifting arms 2 continue to support the pipe to increase the stability of the pipe and improve the cutting accuracy of the pipe cutting machine on the pipe.

[0065] Further, see Figure 3 and Figure 4The support seat 1 includes a fixed plate 11 arranged on the bed 6, and an auxiliary component 111 is arranged on the fixed plate 11, so that when the auxiliary component 111 applies an upward pushing force to the lifting seat 5, the fixed plate 11 supports the auxiliary component 111. Since the fixed plate 11 is arranged on the bed 6, the stability of the auxiliary component 111 is increased, and the pushing effect of the auxiliary component 111 on the lifting seat 5 is further guaranteed, which further reduces the workload of the driving component 3, and further reduces the failure rate of the feeding support device.

[0066] The present application does not make any specific limitation on the structure of the auxiliary component 111. Preferably, the auxiliary component 111 is a cylinder, the cylinder body of the cylinder is fixedly connected to the fixed plate 11, and the piston rod of the cylinder is hinged to the lifting seat 5, so that the cylinder assists in lifting the lifting seat 5 to reduce the workload of the driving component 3, thereby reducing the failure rate of the loading support device.
