The invention will be described in detail below with reference to the drawings in connection with embodiments.
The utility model provides a pipe inner wall plastic spraying device, sets up in the plastic spraying space inside for carry out plastic spraying processing to the inner wall of tubular part, its structure can be illustrated by figure 1. As shown, the present plastic spraying apparatus includes: a supporting frame 2, a translation device, a lifting device and an alignment device.
The supporting frame 2 is used for bearing other components in the device, and when the device works, the supporting frame 2 synchronously moves with a workpiece on the hanging rail 1, so that the purpose of spraying plastics on the inner wall of the pipe in the moving process is realized. Specifically, the support frame 2 is disposed below the suspension rail 1, and a passage hole 11 for allowing the plastic gun 6 to pass through is provided on the top surface of the support frame 1. An alignment device is arranged at the top of the supporting frame, and the pipe 11 to be processed can be clamped through the alignment device, so that the pipe 11 and the channel hole 21 can be ensured to maintain an axial alignment posture.
Optionally, the alignment device includes: the device comprises a first bracket 31, a second bracket 32, an action cylinder 36, a limit turning plate 33 and a limit baffle 34. The first bracket 31 and the second bracket 32 are used for fixing the alignment device, and the first bracket 31 and the second bracket 32 are symmetrically arranged at two sides of the channel hole 21. The first bracket 31 is provided with the limit turning plate 33, and two ends of the limit turning plate 33 are hinged with the first bracket 31. When working, the limiting turning plate 33 is used as a movable part of the alignment device to clamp and limit the pipe 11 needing plastic spraying. The second bracket 32 is provided with a limit baffle 34, and the limit baffle 34 is arranged on one side of the second bracket 32 facing the first bracket 31 and is perpendicular to the horizontal plane. When the limit turning plate 33 contacts with the pipe 11, the limit baffle 34 will prop against the pipe 11 at the other side of the pipe 11, so that the axis of the pipe 11 coincides with the axis of the channel hole 21. The actuating cylinder 36 is arranged on the support frame 2, and the piston rod of the actuating cylinder 36 is hinged with the limit turning plate 33, so that when the piston rod of the actuating cylinder 36 performs telescopic action, the limit turning plate 33 performs turning action. Specifically, when the piston rod is extended, the limit turning plate 33 will turn to a horizontal state, and the structure thereof can be schematically shown in fig. 3. At this time, the pipe 11 to be processed is clamped by the limit turning plate 33 and the limit baffle 34, so that the axial position of the pipe 11 is fixed, and then the plastic spraying work of the inner wall of the pipe can be performed; when the piston rod is shortened, the limit turning plate 33 turns to be in a vertical state, and the structure of the limit turning plate can be schematically shown in fig. 2. At this time, the spraying work of the inner wall of the pipe is completed, the pipe 11 is restored to a free state and follows the hanging rail to enter the next process, and the supporting frame 2 for performing the spraying work is quickly restored to the initial position to clamp the next batch of pipe 11 to be processed.
Optionally, to promote the smoothness of the overturning action of the limit overturning plate 33 and avoid dead points in the overturning process, the bottom of the action cylinder 36 should be hinged with the top surface of the supporting frame 2.
In addition, in order to limit the turning travel of the limiting turning plate 33, the alignment device further comprises a limiting rod 35, the limiting rod 35 is arranged on the first bracket 31, and the limiting rod 35 can limit the limiting position of the vertical state of the limiting turning plate 33, so that the limiting turning plate 33 is prevented from being overturned excessively. Correspondingly, a second limiting rod can be arranged on one side of the first bracket 31 facing the second bracket 32, so that the limiting position of the horizontal state of the limiting turning plate 33 is limited.
In the prior art, in order to reduce damage to the pipe 11 in the hoisting process, only one hoisting point is arranged on the same pipe 11, and the only hoisting point is usually arranged on the side wall of the top of the pipe 11. Because the pipe 11 needs to maintain gravity balance in the hoisting process, the pipe 11 can maintain an inclined state in a hanging state, and the gravity center of the pipe 11 is positioned on the same plumb line with the hoisting hook. When the pipe 11 is in an inclined state, the plastic gun 6 for performing the plastic spraying task on the inner wall of the pipe cannot completely extend into the inner wall of the pipe 11, so that the phenomenon of uneven spraying on the inner wall of the pipe can be caused. In this embodiment, the axis position of the pipe 11 can be corrected by the cooperation of the limit turning plate 33 and the limit baffle 34, so that the pipe 11 and the channel hole 21 maintain an axial alignment posture, and the plastic spraying gun 6 can smoothly enter the pipe 11 to ensure that the inner wall of the pipe is completely sprayed.
Optionally, to improve the correction capability of the alignment device to the axial position of the pipe 11, the level of the limit flap 33 should be greater than the level of the limit baffle 34. When there is a height difference between the limit turning plate 33 and the limit baffle 34, the limit turning plate 33 and the limit baffle 34 will form two supporting points with different heights on two sides of the pipe 11. Specifically, the lower limit baffle 34 will support the bottom end of the pipe 11, and the higher limit baffle 33 will support the middle of the pipe 11, so that the clamped pipe 11 will maintain absolute alignment with the channel hole 21, so as to ensure that the pipe inner wall obtains the best spraying effect.
In addition, since the pipes 11 processed on the same line may have different specifications, it is necessary that the alignment device be capable of performing clamping correction for the pipes 11 of various specifications. Optionally, a V-shaped limit groove 331 for accommodating the pipe 11 is provided on the limit flap 33, and when the limit flap 33 is in a horizontal state, an opening side of the limit groove 331 faces the second bracket 32. The adaptability of the alignment device to the pipes 11 with different diameters can be improved by arranging the V-shaped limiting cutting grooves 331, when the diameter of the pipe 11 is large, the depth of the pipe 11 entering the limiting cutting grooves 331 is low, and the inner wall, close to the opening side, of the limiting cutting grooves 331 can resist the pipe 11; when the diameter of the pipe 11 is smaller, the depth of the pipe 11 entering the limit slot 331 is larger, and the inner wall of the limit slot 331 near the bottom will support the pipe 11.
Optionally, in order to reduce the collision force between the limiting turning plate 33 and the pipe 11 and avoid damage to the pipe 11 during the clamping process, a buffer plate is arranged on the bottom surface of the limiting turning plate 33, and a containing groove corresponding to the limiting cutting groove 331 is arranged on the buffer plate. Specifically, the buffer plate can be made of silica gel, and when the bottom surface of the limiting turning plate 33 contacts with the pipe 11 in an inclined state, the buffer plate can locally deform to reduce the impact between the limiting turning plate and the pipe 11, so that damage to the pipe 11 is avoided.
In this embodiment, the translational movement of the supporting frame 2 is implemented by a translational device, the translational device is disposed at the bottom of the supporting frame 2, and drives the supporting frame 2 and the pipe 11 to be processed to make synchronous movement through the translational device, and drives the supporting frame 2 to reset after the plastic spraying is completed. Specifically, the translation device includes: a guide rail 44, a first drive motor 41 and a drive rack 42. Wherein the transmission rack 42 is arranged on the bottom surface of the support frame 2, the transmission rack 42 is parallel to the hanging rail 1, a first transmission gear 411 meshed with the transmission rack 42 is arranged on the output shaft of the first driving motor 41, and when the first driving motor 41 is started, the torque generated inside the first driving motor 41 is transmitted to the transmission rack 42 through the first transmission gear 411, so that the support frame 2 performs translational motion. Furthermore, in order to limit the movement path of the support frame 2, the translation device also comprises a guide track 44 and a guide wheel 43. Specifically, the guide rails 44 are disposed on two sides of the support frame 2, and guide wheels 43 matched with the guide rails 44 are disposed on the support frame 2, and when the support frame 2 moves, the guide wheels 43 roll along the guide rails 44.
When the alignment device finishes clamping and correcting the pipe 11, the translation device drives the support frame 2 to perform translation movement, and the movement is the same as the movement direction of the pipe 11 and the speed is equal to the movement direction of the pipe 11, so that the support frame 2 and the pipe 11 are kept in a relatively static state at the moment, and the lifting device drives the plastic spraying gun 6 to extend into the pipe 11 for spraying. After the spraying process is finished, the alignment device will end the clamping of the pipe 11, and at this time, the supporting frame 2 will quickly restore to the initial position, so as to facilitate the plastic spraying process on the next batch of pipe 11.
The lifting device is arranged inside the supporting frame 2, a plastic spraying gun 6 is arranged at the top of the lifting device, the plastic spraying gun 6 is axially aligned with the channel hole 21, and the structure of the lifting device can be schematically shown in fig. 1 and 4. As shown, the elevating device includes: a support plate 51, a second drive motor 52, a drive shaft 53, a chain 55 and a direction-changing wheel 54. The transmission shaft 53 is arranged on the bottom surface of the support frame 2, a second transmission gear is arranged on the transmission shaft 53, the second transmission gear is meshed with a driving tooth arranged on the output shaft of the second driving motor 52, and when the second driving motor 52 is started, the torque generated in the second driving motor 52 drives the transmission shaft 53 to rotate. The direction-changing wheel 54 is arranged at the bottom of the top surface of the supporting frame 2, and the direction-changing wheel 54 is connected with a driving sprocket arranged on the transmission shaft 53 through a chain 55, and when the transmission shaft 53 starts to rotate, the chain 55 moves around the driving sprocket and the direction-changing wheel 54. The supporting plate 51 is disposed inside the supporting frame 2, and the supporting plate 51 is connected with a chain 55, when the chain 55 moves, the chain 55 drives the supporting plate 51 to lift, so as to drive the plastic gun 6 to insert into or withdraw from the pipe 11.
Optionally, to improve the accuracy of the lifting movement of the support plate 51, the lifting device includes a guide groove 511, where the guide groove 511 is disposed inside the support frame 2, and correspondingly, a guide slider matched with the guide groove 511 is disposed on a side wall of the support plate 51, and the guide slider is disposed inside the guide groove 511. In addition, in order to prevent the support plate 51 from excessively ascending or descending, a baffle may be provided inside the guide groove 511, thereby restricting the limit position of the support plate 51.
