Description

Technical Field

[0001] This utility model relates to the field of polishing technology, specifically to an automated polishing equipment for casting water meter casings. Background Technology

[0002] Water meters, as water measuring instruments, are widely used in daily life and industrial production. The water meter casing is the main component of the water meter, providing the water flow channel and installation space for other parts. Currently, most water meter casings on the market are made of ductile iron. The finished water meter casing will have many defects such as flash, burrs, and residual gates, which need to be polished before machining.

[0003] Due to the diverse shapes and sizes of water meter casings, manual grinding with a grinding wheel is currently the most common method. Workers hold the water meter casing and use a grinding wheel to remove burrs, flash, and residual gates. While this method ensures high grinding efficiency, it requires a certain level of skill from the workers and results in inconsistent grinding, often leading to under- or over-grinding. Furthermore, the grinding work is physically demanding, and the high-speed rotation of the grinding wheel poses a certain degree of danger; the noise and dust generated during grinding can cause physical harm to workers. Currently, manual grinding employs a multi-worker assembly line approach, with each worker responsible for grinding one or more areas. This method requires 4-5 people per line, resulting in high labor costs for businesses. Existing grinding equipment is also limited in function and application, and its current design is inconvenient for handling irregularly shaped water meters. Utility Model Content

Figure 2 and Figure 3 As shown, in this embodiment, a first servo motor 21 is fixedly connected to the positioning plate 19, a lower clamping fixture 20 is fixedly connected to the rotating shaft of the first servo motor 21, a column 10 is fixedly connected to the positioning plate 19, a support plate 18 is fixedly connected to the column 10, a bracket seat 17 is fixedly connected to the support plate 18, a bracket 3 is hinged to the bracket seat 17, and an upper clamping fixture 2 is rotatably connected to the bracket 3. The upper clamping fixture 2 and the lower clamping fixture 20 can rotate and adjust the angle of the water meter. Two arms 16 are hinged to the support plate 18, and a connector 22 is hinged between the two arms 16. The connector 22 is hinged to the bracket 3. One end of the piston rod of the cylinder 5 is also hinged between the two arms 16. The cylinder 5 is hinged to the support plate 18. By starting the cylinder 5, the extension and retraction of the piston rod is controlled, which drives the arms 16 and the connector 22 to rotate by an angle. Then, the connector 22 drives the bracket 3 to rotate by a certain angle along the bracket seat 17. The upper clamping fixture 2 completes the clamping and releasing of the water meter. like Figure 1 and Figure 6 As shown, in this embodiment, a second arc-shaped mounting plate 15 is fixedly connected to the workbench 24, a cross slide 12 is fixedly connected to the second arc-shaped mounting plate 15, and a grinding wheel 11 is fixedly connected to the slide of the cross slide 12. The grinding wheel 11 can adjust its position with the cross slide 12 to complete the curve grinding. The optical shaft 26 is slidably connected to the second arc-shaped mounting plate 15. The top of the optical shaft 26 is fixedly connected to the first arc-shaped mounting plate 9. The motor base 7 is fixedly connected to the first arc-shaped mounting plate 9. The motor 8 is fixedly connected to the motor base 7. The grinding head 6 is fixedly connected to the rotating shaft of the motor 8. Starting the motor 8 can drive the grinding head 6 to grind the water meter. The first arc-shaped mounting plate 9 is located above the second arc-shaped mounting plate 15. The bottom end of the optical shaft 26 is fixedly connected to the piston rod of the hydraulic cylinder 14. The hydraulic cylinder 14 is fixed to the ground. Starting the hydraulic cylinder 14 can make the first arc-shaped mounting plate 9 move up and down. The grinding head 6 moves up and down with the first arc-shaped mounting plate 9, and the grinding range is larger. A second servo motor 23 is fixedly connected to the workbench 24. The shaft of the second servo motor 23 is fixedly connected to the input shaft of the reduction motor 25. The second motor 23 drives the water meter to rotate to the first grinding station. The grinding wheel 11 completes the grinding of the first position of the water meter shell. After the grinding of the first station is completed, the second servo motor 23 is driven to rotate to the second station again. The grinding head 6 completes the second part of the grinding. A loading robot 1 is placed on one side of the second arc-shaped mounting plate 15 to complete the loading and unloading.

[0019] The working principle of this utility model is as follows: The loading robot 1 loads the water meter using grippers. The lower fixture 20 and the upper fixture 2 work together to clamp the water meter. The first servo motor 21 can be controlled to rotate according to the grinding position to complete the adjustment. After loading is completed, the second servo motor 23 is started to rotate. The turntable 13 and the water meter on the fixture rotate to the first grinding station, where the grinding wheel 11 completes the grinding of the first position of the water meter shell. After the grinding of the first station is completed, the second servo motor 23 is driven to rotate to the second station again. At the same time, the first servo motor 21 rotates at a certain angle to change the orientation of the water meter shell. Then, the grinding head 6 grinds the second position; and so on. Since multiple sets of water meter housing fixtures are evenly distributed on the turntable 13, when the first water meter housing is rotated to the first grinding station, the water meter housing fixture behind it is also rotated to the loading and unloading station, and then the loading robot 1 completes a loading operation. Each grinding station has a grinding tool grinding the corresponding position of the water meter housing, thus forming a production line grinding. When the water meter housing is finished grinding, it returns to the loading and unloading station. At this time, the upper fixture fixture 2 opens, and the loading robot 1 unloads the water meter through the gripper.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
