Description

Technical Field

[0001] This utility model relates to polishing equipment technology, specifically an inner wall polishing device for pipe processing of a vortex flow meter. Background Technology

[0002] A vortex flow meter is an instrument used to measure fluid parameters. Its housing is usually a pipe-like rotating body, and the inner wall of the housing needs to be polished by polishing equipment during production.

[0003] Existing equipment for polishing the inner walls of pipes typically places the pipe outside two rotatable rollers. A lifting mechanism above the pipe drives a limiting wheel to abut the upper part of the pipe, allowing it to rotate with the lower rollers. Then, a polishing wheel on one side extends into the pipe along with its shaft end for polishing. As described above, during processing, the pipe needs to be in contact with the two lower rollers to rotate, thus placing it in a recessed area between the rollers. After processing, the pipe can only be removed after the positioning wheel has risen a certain distance in a straight line; otherwise, the positioning wheel, before reaching the designated height, will restrict the pipe removal operation for a certain period. This characteristic limits the speed of pipe unloading, accumulating significant time delays when processing pipes containing multiple swirl flow meters. Therefore, we propose an inner wall polishing device for processing swirl flow meter pipes to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an inner wall polishing device for pipe processing of a vortex flow meter, in order to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: it includes a main frame, on which a pipe rotation mechanism is provided;

[0006] A side frame is also provided on one side of the main frame, and a polishing mechanism is provided on the side frame;

[0007] A fixed frame is fixedly provided on the top rear side of the main frame, and a lifting mechanism is provided on the fixed frame. A lifting plate is fixedly provided at the output end of the lifting mechanism.

[0008] The bottom of the lifting plate is provided with a limiting mechanism, which includes a guide plate fixed to the rear side of the bottom of the lifting plate. The guide plate has a guide groove, and a guide rod is movably connected in the guide groove. One end of the guide rod is provided with a connecting plate, and the other end of the connecting plate is provided with a positioning shaft. A positioning wheel is fixed outside the positioning shaft, and a telescopic mechanism is also provided on the outer side of one end of the positioning shaft. A bracket is fixed to the front side of the bottom of the lifting plate, and a rotating shaft is rotatably connected in the bracket. An electric cylinder is fixed on the outer side of one end of the rotating shaft, and the output end of the electric cylinder is rotatably connected to one end of the guide rod.

[0009] An auxiliary positioning mechanism is also provided on one side of the bottom of the lifting plate.

[0010] Preferably, the auxiliary positioning mechanism includes a side plate fixed to one side of the bottom of the lifting plate. A small gear and a large gear are respectively arranged obliquely on the upper and lower sides of one side of the side plate. The large gear is fixed to the outside of the rotating shaft. A connecting shaft is rotatably connected to the side plate. The small gear is fixed to the outside of the connecting shaft and meshes with the large gear. A swing arm is fixed to the outside of one end of the connecting shaft, and a positioning plate is fixed to the end of the swing arm.

[0011] Preferably, the telescopic mechanism includes a sliding block slidably connected to the bottom of the lifting plate, a telescopic rod fixed to the bottom of the sliding block, and the end of the telescopic rod being hinged to the outer side of one end of the positioning shaft.

[0012] Preferably, the cross-sectional trajectory of the guide groove is composed of a straight line and an arc, wherein the arc is located in front of the straight line.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By using the limit mechanism and telescopic mechanism, the positioning wheel can be moved to the rear and upper part of the pipe of the swirl flow meter immediately after the pipe processing is completed. This allows the pipe of the swirl flow meter to be picked up and unloaded immediately, avoiding interference of the positioning wheel with the pipe unloading operation and improving the unloading speed of the pipe.

[0015] 2. Through the auxiliary positioning mechanism, the positioning plate can be rotated in the opposite direction during the loading and unloading process. At the same time, by controlling the transmission ratio, the rotation angle of the positioning plate is made greater than the rotation angle of the electric cylinder. When the electric cylinder drives the positioning wheel to move, it can synchronously drive the position of the positioning plate to change. This allows the end face of the pipe to be positioned during the next loading after unloading, while the end face positioning is canceled when polishing is required. This ensures the compactness of the processing actions before and after processing and further shortens the processing time. Attached Figure Description

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figures 1-5 As shown, an inner wall polishing device for pipe processing of a swirl flow meter includes a main frame 1, on which a pipe rotating mechanism 2 is provided. The pipe rotating mechanism 2 includes two rotating rollers rotatably connected to the main frame 1. The two ends of the rotating rollers are respectively connected to the output end of one of the motors through a chain belt and a sprocket. The rotating rollers are driven to rotate by the motor, so as to drive the pipe placed above them to rotate.

[0025] A side frame 3 is also provided on one side of the main frame 1. A polishing mechanism 4 is provided on the side frame 3. The polishing mechanism 4 includes a moving mechanism that can move along the roller axis and a rotating mechanism that can drive the polishing wheel to rotate. A polishing shaft is fixed at the output end of the rotating mechanism, and a polishing wheel is fixed at the end of the polishing shaft. The polishing wheel is driven into the pipe placed on the rotating roller by the moving mechanism. Then, the polishing shaft and polishing wheel are driven to rotate by the rotating mechanism to polish the inner wall of the pipe placed on the rotating roller.

[0026] A fixed frame 5 is fixedly installed on the top rear side of the main frame 1. A lifting mechanism 6 is installed on the fixed frame 5. A lifting plate 7 is fixedly installed at the output end of the lifting mechanism 6. The lifting mechanism 6 can be driven by a mechanism such as an electric cylinder, so that the lifting plate 7 can move up and down. The pipes used to cooperate with the swivel flow meters of different diameters are positioned by the positioning wheel 13.

[0027] The bottom of the lifting plate 7 is provided with a limiting mechanism, which includes a guide plate 8 fixedly mounted on the rear side of the bottom of the lifting plate 7. A guide groove 9 is provided on the guide plate 8, and a guide rod 10 is movably connected within the guide groove 9. A connecting plate 11 is provided at one end of the guide rod 10, and a positioning shaft 12 is rotatably mounted inside the other end of the connecting plate 11. A positioning wheel 13 is fixedly mounted outside the positioning shaft 12. A telescopic mechanism is also provided on the outer side of one end of the positioning shaft 12. A bracket 15 is fixedly mounted on the front side of the bottom of the lifting plate 7, and a rotating shaft 16 is rotatably connected within the bracket 15. An electric cylinder 17 is fixedly mounted on the outer side of one end of the rotating shaft 16. The output end is rotatably connected to one end of the guide rod 10. The guide groove 9 is used to guide the movement direction of the guide rod 10. The positioning wheel 13 is used to limit and position the top of the pipe into the flow meter. The bracket 15 is used to support and fix the rotating shaft 16. The electric cylinder 17 is used to push the guide rod 10 to move back and forth in the guide groove 9. The telescopic mechanism includes a sliding block 24 slidably connected to the bottom of the lifting plate 7. A telescopic rod 14 is fixed to the bottom of the sliding block 24. The end of the telescopic rod 14 is hinged to the outer side of one end of the positioning shaft 12. The telescopic rod 14 can adjust its height as the connecting plate 11 moves. The moving block 24 can move along the connecting plate 11, thereby driving the telescopic rod 14 to move, so as to avoid interference when the connecting plate 11 moves with the guide rod 10. Secondly, the telescopic mechanism can ensure that the connecting plate 11 always maintains a certain angle when it moves with the guide rod 10, so that the guide rod 10 cannot drive the connecting plate 11 to rotate. This ensures that the positioning wheel 13 will not lift up when it squeezes the pipe of the positioning flow meter, thus ensuring the stability during positioning and limiting. After the pipe of the spiral flow meter is polished, the controller controls the electric cylinder 17 to work, so that it pushes the guide rod 10 to move backward along the guide groove 9. The device will first tilt backward along an arc, at which point the length of the telescopic rod 14 will shorten accordingly. The sliding block 24 will slide under the lifting plate 7, and the electric cylinder 17 will drive the rotating shaft 16 to rotate at a certain angle. At this time, the processed pipe of the swirl flow meter can be directly removed. Through the cooperation of the set limit mechanism and telescopic mechanism, the positioning wheel 13 can be moved to the rear and upper part of the swirl flow meter pipe as soon as the pipe is processed, so that the pipe of the swirl flow meter can be removed and unloaded as soon as possible, avoiding interference of the positioning wheel 13 with the pipe unloading operation and improving the unloading speed of the pipe.

[0028] In this embodiment, the auxiliary positioning mechanism includes a side plate 18 fixed to one side of the bottom of the lifting plate 7. A small gear 19 and a large gear 20 are obliquely arranged on the upper and lower sides of one side of the side plate 18, respectively. The large gear 20 is fixed to the outside of the rotating shaft 16. A connecting shaft 21 is rotatably connected to the side plate 18. The small gear 19 is fixed to the outside of the connecting shaft 21 and meshes with the large gear 20. A swing arm 22 is fixed to the outside of one end of the connecting shaft 21, and a positioning plate 23 is fixed to the end of the swing arm 22. The side plate 18 is used to support and fix the connecting shaft 21 and the rotating shaft 16. The meshing of wheel 19 and large gear 20 allows connecting shaft 21 and rotating shaft 16 to rotate in opposite directions, with the rotation angle of connecting shaft 21 being greater than that of rotating shaft 16. This is so that when electric cylinder 17 drives rotating shaft 16 to rotate by a certain angle and pushes guide rod 10 backward, rotating shaft 16 drives large gear 20 to rotate, causing small gear 19 to drive connecting shaft 21 and swing arm 22 to rotate in opposite directions by a large angle, thus rotating positioning plate 23 above roller shaft. This allows the operator to place the new flow meter pipe on roller shaft and align one end with one side of positioning plate 23 for easy positioning.

[0029] In this embodiment, the cross-sectional trajectory of the guide groove 9 is composed of a straight line and an arc, with the arc located in front of the straight line. By providing the presence of the arc segment, the connecting plate 11 can move obliquely when it moves with the guide rod 10 in the guide groove 9, avoiding the blockage caused by strong extrusion between the positioning wheel 13 and the pipe surface of the processed swirl flow meter due to direct horizontal movement, so as to achieve a smooth and fluid retraction of the positioning wheel 13.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
