Description

Technical Field

[0001] The present application relates to the field of powder tank welding, and in particular to a powder tank special-shaped roller frame. Background Art

[0002] The roller frame is used to support the powder tank. A roller is arranged on the roller frame. The roller abuts against the powder tank. There is friction between the roller and the powder tank. The rotation of the roller drives the powder tank to rotate to complete the welding of the annular weld on the outer side of the powder tank.

[0003] Most of the existing roller frames are designed for cylinders with the same diameter at both ends. Therefore, the heights of the roller frames are the same, and the roller frames are placed at the two ends of the powder can, so that the roller frames drive the powder can to rotate.

[0004] The above-mentioned prior art solution has the following defects: for the irregular-shaped cans with inconsistent diameters at both ends, the roller racks with consistent heights make the central axis of the irregular-shaped cans in an inclined state, causing the irregular-shaped cans to slide down along the central axis during rotation. Utility Model Content

[0005] In order to make the central axis of the special-shaped can be in a horizontal position during processing, the present application provides a special-shaped roller frame for a powder can.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A powder can special-shaped roller frame includes a clamping part, a lifting part and a sliding part. At least two clamping parts are provided, and a lifting part is provided under each clamping part. The lifting part is fixedly connected to the clamping part, and the lifting part is slidably connected to the sliding part; the lifting part includes a cylinder and a bearing plate, the bearing plate is slidably connected to the sliding part, the cylinder is fixedly connected to the bearing plate, and one end of the cylinder away from the bearing plate is fixedly connected to the lifting part, and the height of the clamping part is controlled by adjusting the height of the cylinder.

[0008] By adopting the above scheme, the cylinder is connected to the clamping part during processing of the special-shaped can. By adjusting the height of the cylinder, the height of the two clamping parts is adjusted, and then the special-shaped can is hoisted to the clamping part, so that the two clamping parts are respectively abutted against the parts with inconsistent diameters at both ends of the special-shaped can. At this time, the central axis of the special-shaped can with inconsistent diameters at both ends is in a horizontal state, thereby achieving the purpose of keeping the central axis of the special-shaped can in a horizontal position during processing.

[0009] Furthermore, each lifting part is provided with at least two cylinders for strengthening the support for the clamping part.

[0010] By adopting the above solution, the cylinder is fixedly connected to the clamping part, and the lifting and lowering of the cylinder is used to control the lifting and lowering of the clamping part. If more than two cylinders are provided, the stability of the clamping part when supported by the lifting part is enhanced, and the stability of the tank body during welding is further improved.

[0011] Furthermore, the sliding part includes a base, a bidirectional screw and a slider. The base is provided with a groove, the bidirectional screw is located in the groove, both ends of the bidirectional screw are rotatably connected to the groove, and two sliders are provided, both of which are located in the groove. The two sliders are threadedly connected to the bidirectional screw. The bidirectional screw is used to control the two sliders to move closer or farther away from each other, and each slider is fixedly connected to a supporting plate.

[0012] By adopting the above scheme, a groove is opened on the base, and the groove is used to place the bidirectional lead screw. When the bidirectional lead screw rotates, the groove is used to limit the bidirectional lead screw. Two sliders are provided, which are located in different rotation directions of the bidirectional lead screw. The two sliders are fixedly connected to the bidirectional lead screw. The rotation of the bidirectional lead screw can drive the two sliders to move closer or farther away. Each slider is connected to a supporting plate, so that the approach or distance of the slider can drive the approach or distance of the supporting plate.

[0013] Furthermore, the bidirectional lead screw is provided with a driving member, which is fixedly connected to the base and is used to drive the bidirectional lead screw to rotate along its own axis in the groove.

[0014] By adopting the above solution, the bidirectional lead screw is arranged in the groove, and the rotation of the bidirectional lead screw can drive the slider threadedly connected to the bidirectional lead screw to move. The driving member is fixedly connected to the base, and the driving member can drive the bidirectional lead screw to rotate.

[0015] Furthermore, each of the clamping parts includes a clamping arm, a roller and a U-shaped frame. At least four clamping arms are provided. Each clamping arm is connected to a roller. The roller is rotatably connected to the clamping arm, and the roller abuts against the special-shaped can. The two clamping arms are hinged to each other, and the hinge is fixedly connected to the U-shaped frame. A stretching structure is provided between the end of the clamping arm away from the roller and the clamping arms that are hinged to each other, and the stretching structure is used to control the angle of the clamping arms.

[0016] By adopting the above scheme, the clamping part is used to clamp the special-shaped cans, each clamping part is provided with four clamping arms, each clamping arm is provided with a roller, the roller abuts against the can body, there is friction between the roller and the can body, the rotation of the roller can drive the can body to rotate along its own axis, the two clamping arms are hingedly arranged, the angle of the clamping arms can be changed, so that the clamping part can clamp special-shaped cans of different diameters, and a stretching structure is provided at the hinge.

[0017] Furthermore, the stretching structure is configured as a stretching spring, and two ends of the stretching spring are respectively fixedly connected to two clamping arms hinged to each other.

[0018] By adopting the above scheme, the two clamping arms are hingedly arranged, and a tension spring is arranged at the hinge. When welding the special-shaped tank, a hanger is used to place the two ends of the special-shaped tube on the two clamping parts, and the outer wall of the special-shaped tank abuts against the roller. The special-shaped tank can drive the tension spring to stretch or contract, so that the clamping part can clamp tanks of different diameters.

[0019] Furthermore, each of the rollers is fixedly connected to a motor, and the motor is used to drive the roller to rotate.

[0020] By adopting the above solution, a motor is provided on each roller, and the motor is used to drive the roller to rotate. There is friction between the special-shaped can and the roller. The rotation of the roller drives the special-shaped can to rotate along its own axis and thus completes the annular welding of the special-shaped can.

[0021] Furthermore, each of the clamping parts has a roller fixedly connected to a motor, and the motor is used to drive the roller to rotate.

[0022] By adopting the above scheme, each clamping part has a roller fixedly connected to a motor, the motor is used to drive the roller to rotate, there is friction between the special-shaped can and the roller, the rotation of the roller drives the special-shaped can to rotate along its own axis and thus completes the annular welding of the special-shaped can.

[0023] Furthermore, the motor includes a second motor and a third motor, the second motor and the third motor are respectively arranged in two clamping parts, and the second motor and the third motor have different rotation speeds.

[0024] By adopting the above scheme, each clamping part has a roller equipped with a motor, and the rotation speeds of the two motors are different. When welding the special-shaped tank, a sling is used to place the two ends of the special-shaped tank on the two clamping parts, and the roller abuts against the special-shaped tank. There is friction between the roller and the special-shaped tank, and the motor is driven. The motor drives the roller to rotate, and the roller drives the special-shaped tank to rotate along its own axis. Because the diameters of the two ends of the special-shaped tank are different, two motors with different rotation speeds are set to make the two ends of the special-shaped tank rotate synchronously, thereby completing the circular welding.

[0025] In summary, this application has the following technical effects:

[0026] By setting up a roller frame, the cylinder is connected to the clamping part during processing of the special-shaped can. By adjusting the height of the cylinder, the height of the two clamping parts is adjusted, so that the central axis of the special-shaped can with inconsistent front and rear diameters is in a horizontal state, avoiding the special-shaped can from falling along the tilted direction of the axis due to the tilt of the central axis of the special-shaped can during processing;

The sliding part is located at one end of the lifting part away from the clamping part. The two lifting parts are both slidably connected to the sliding part. The sliding part can drive the two lifting parts to approach or move away from each other, thereby driving the two clamping parts to approach or move away from each other, so that the two clamping parts can clamp special-shaped cans of different lengths.

In this embodiment, each clamping part is provided with four clamping arms 8, two tension springs 9, four rollers 81 and a U-shaped frame 7. Two clamping arms 8 are respectively provided at both ends of the U-shaped frame 7. The two clamping arms 8 are hingedly arranged, and the hinge shaft is fixedly connected to the U-shaped frame 7. One end of each clamping arm 8 is rotatably connected to a roller 81. A tension spring 9 is used to connect the end of each clamping arm 8 away from the roller 81 to the mutually hinged clamping arm 8. The two ends of the tension spring 9 are respectively fixedly connected to the two clamping arms 8. The tension spring 9 is used to control the clamping angle of the clamping arm 8 so that the clamping arm 8 clamps To hold special-shaped cans of different diameters, each clamping part has a roller 81 connected to a motor, that is, a roller 81 in one clamping part is connected to the second motor 10, and a roller 81 in the other clamping part is connected to the third motor 20. Since the diameters at both ends of the special-shaped can 1 are different, the linear speeds of rotation per unit time are different. Therefore, the rotation speeds of the second motor 10 and the third motor 20 are different, so that the two ends of the special-shaped can 1 rotate synchronously; this embodiment also provides a method, each roller 81 is fixedly connected to a motor, the motor is used to drive the roller to rotate, and the rotation of the roller drives the special-shaped can abutting against the roller to rotate along its own axis, thereby completing the annular welding of the special-shaped can.

[0038] Reference Figure 2 and Figure 4 Each lifting part includes a cylinder 6 and a bearing plate 5. The lifting part in this embodiment is provided with two cylinders 6 and a bearing plate 5. The cylinder 6 is fixedly connected to both ends of the bearing plate, and one end of the cylinder 6 away from the bearing plate 5 is fixedly connected to the U-shaped frame 7.

[0039] Reference Figure 4 and Figure 5 The sliding part includes a slider 41, a bidirectional lead screw 4 and a base 3. The base 3 is fixed on the working surface. A groove 31 is provided at the top of the base 3. The bidirectional lead screw 4 is arranged in the groove 31. Both ends of the bidirectional lead screw 4 are rotatably connected to the two side walls of the groove 31. A first motor 2 is provided at one end of the bidirectional lead screw 4. The first motor 2 is fixedly connected to the bidirectional lead screw 4. The first motor 2 is used to drive the bidirectional lead screw 4 to rotate around its own axis in the groove 31. The bidirectional lead screw 4 is a lead screw with two sections of threads with opposite rotation directions. The two sliders 41 are respectively arranged on two sections of threads with different rotation directions. The slider 41 is threadedly connected to the bidirectional lead screw 4. The slider 41 is fixedly connected to the bearing plate 5. By controlling the rotation of the bidirectional lead screw 4, the sliders 41 can be driven to approach or move away from each other. The approach or move away of the sliders 41 can drive the bearing plate 5 to approach or move away from each other.

[0040] The implementation principle of the powder tank special-shaped roller 81 frame of the embodiment of the present application is as follows: when the special-shaped tank 1 is annularly welded, the first motor 2 is first driven, and the first motor 2 drives the bidirectional lead screw 4 to rotate along its own axis, thereby driving the two sliders 41 to move closer to or farther away from each other, and the slider 41 can drive the cylinder 6 to move through the bearing plate 5 and then drive the movement of the U-shaped frame 7, so that the two clamping parts can clamp special-shaped tanks of different lengths; then adjust the height of the cylinder 6 to drive the two U-shaped frames 7 to rise and fall, so that the two U-shaped frames 7 keep the central axis of the special-shaped tank 1 with inconsistent diameters at both ends in a horizontal state; then use a hanger to place the special-shaped tank 1 on the two clamping parts, and the rollers on the two clamping parts The shaped tank 1 abuts against the outer wall of the shaped tank 1, and the shaped tank 1 drives the two hinged clamping arms 8 to open, and drives the tension spring 9 to extend, so that the two hinged clamping arms 8 are suitable for clamping shaped tanks 1 of different diameters; finally, the second motor 10 and the third motor 20 are driven, and the second motor 10 and the third motor 20 drive the roller 81 to rotate. There is friction between the roller 81 and the shaped tank 1. The rotation of the roller 81 drives the shaped tank 1 to rotate along its own axis, and then starts to perform circular welding on the outer wall of the shaped tank 1. After welding, the shaped tank 1 is lifted up with a hoist. When the shaped tank 1 is separated from the clamping arm 8, the opening of the two hinged clamping arms 8 becomes smaller under the elastic action of the tension spring 9.
