Abstract
Description
Technical Field
[0001] This utility model relates to the field of polishing machine technology, and in particular to a multi-station synchronous grinding and polishing machine for outer circles. Background Technology
[0002] A multi-station synchronous external cylindrical grinding and polishing machine is a specialized machine for grinding and polishing the outer cylindrical surface of workpieces. It includes a machine body, multiple grinding and polishing stations, and a transmission and control system. The stations can operate simultaneously, with the grinding and polishing wheels rotating at high speed to remove defects from the outer cylindrical surface of the workpiece. Using this machine significantly improves production efficiency, allowing for simultaneous rough grinding, fine grinding, and polishing of multiple workpieces or different parts of a single workpiece, much faster than traditional methods. It ensures consistent processing quality through precise parameter control, avoiding quality variations caused by manual operation. Furthermore, it reduces labor intensity and costs, decreasing reliance on manpower and production costs. In addition, it can be adjusted to adapt to the processing of outer cylindrical surfaces of workpieces of different sizes and shapes.
[0003] Multi-station synchronous external cylindrical polishing machines include semi-automatic and fully automatic models. The semi-automatic model uses a motor to drive the polishing wheel and guide wheel to rotate via a transmission device. The workpiece is fixed by a clamp or chuck, and a simple conveying mechanism moves the workpiece under the guidance of the guide wheel. The workpiece contacts the high-speed rotating polishing wheel, where defects are removed through abrasive friction. Multiple stations work together to achieve different degrees of polishing.
[0004] In most cases, existing polishing machines use a handwheel and lead screw to adjust the polishing force of a single polishing machine to polish the pipe fittings. However, because the adjustment force of the polishing machine cannot be kept consistent at different times and by different personnel, it will lead to inconsistent polishing degree of the pipe fittings, resulting in a decline in production quality. Therefore, a multi-station external cylindrical synchronous polishing machine is proposed to solve the above problems. Utility Model Content

Detailed Implementation
[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] Reference Figure 1 - Figure 6This utility model provides an embodiment of a multi-station synchronous external cylindrical grinding and polishing machine, comprising a machine body 1, which is the main frame of the entire equipment, providing a mounting foundation and stable support for other components. A control panel 2 is fixedly connected to one side of its outer wall. The control panel 2 is used to control the start, stop, and various parameter settings of the equipment. A protective cover 3 is fixedly connected to the upper surface of the machine body 1. The protective cover 3 prevents debris generated during grinding and polishing from flying and injuring people, and also prevents external debris from entering the equipment and affecting normal operation. A switch door 4 is rotatably connected to the outer wall of the protective cover 3, facilitating the operator's inspection, maintenance, and replacement of parts inside the equipment. Multiple support seats 5 are provided on the top of the machine body 1. The support seats 5 support motors 6 and other related components. The upper surface of the support seats is fixedly connected to the motors 6, which are key components providing power and driving the polishing wheel 11 to rotate, thus achieving grinding and polishing of the pipe fittings. A fixed cylinder 7 is fixedly connected to one side of the outer wall of the support 5. The fixed cylinder 7 provides rotational support for the rotating rod 8. The rotating rod 8 is rotatably connected inside the fixed cylinder 7. A belt 9 is connected between the rotating rod 8 and the output end of the motor 6. The power of the motor 6 is transmitted to the rotating rod 8 through the belt 9, which drives the rotating rod 8 to rotate, thereby causing the polishing wheel 11 to rotate. A slide rail 10 is fixedly connected to the upper surface of the machine body 1. The slide rail 10 provides guidance and support for the movement of the support 5, so that the support 5 can slide smoothly. The support 5 is slidably connected to the outer wall of the slide rail 10. A polishing wheel 11 is provided on the outer wall of the rotating rod 8. The polishing wheel 11 directly contacts the pipe and polishes the outer circle of the pipe by high-speed rotation. A limit wheel 21 is rotatably connected to the upper surface of the machine body 1. The limit wheel 21 can guide the movement direction of the pipe in the equipment, so that the pipe can be polished in the appropriate position. An adjustment component for adjusting the distance of the support 5 is installed inside the protective cover 3.
[0028] The adjustment assembly includes a bidirectional lead screw 12, which is the core transmission component for adjusting the distance of the support base 5. Its outer wall is rotatably connected inside the protective cover 3. Multiple threaded sleeves 13 are threadedly connected to the outer wall of the bidirectional lead screw 12. When the bidirectional lead screw 12 rotates, the threaded sleeves 13 can move along the lead screw 12. Symmetrical rotating plates 14 are rotatably connected to the outer walls of the threaded sleeves 13. The rotating plates 14 convert the linear motion of the threaded sleeves 13 into rotational motion. One rotating plate 14 is rotatably connected to one side of the inner wall of the protective cover 3, and the other rotating plate 14 is rotatably connected to one side of the outer wall of the support base 5. Through this connection method, when the bidirectional lead screw 12 rotates, the support base 5 can be moved, thereby adjusting the distance between the polishing wheels 11 to meet the grinding and polishing needs of pipes of different lengths. The protective cover 3 is equipped with... A limiting assembly for limiting the position of pipe fittings; the limiting assembly includes a rotating column 15, the outer wall of which is rotatably connected to the inside of the protective cover 3.

A left-right symmetrical limiting wheel 19 is rotatably connected to the outer wall of the sliding block 18. The limiting wheel 19 contacts the pipe fitting and can automatically adjust its position according to the size change of the pipe fitting, with the cooperation of the spring 17 and the sliding block 18, to stably limit the pipe fitting, ensuring accurate positioning of the pipe fitting during grinding and polishing, and improving processing accuracy.
[0029] Reference Figure 1 - Figure 6A mounting sleeve 22 is fixedly connected to one side of the outer wall of the rotating rod 8. The mounting sleeve 22 provides an installation position for the fixing component and the quick-release component. A fixing component for fixing the polishing wheel 11 is installed on one side of its outer wall. This component can ensure the stability of the polishing wheel 11 during operation. A quick-release component for quickly removing the polishing wheel 11 is installed on the other side of its outer wall, which facilitates the replacement of the polishing wheel 11. The fixing component includes a connecting block 23. The connecting block 23 is used to connect the mounting sleeve 22 and other components. One side of its outer wall is fixedly connected to the mounting sleeve. On one side of the outer wall of the 22 connecting block 23, a rod 24 is fixedly connected. The rod 24 can be inserted into the polishing wheel 11 for initial positioning. A spring 25 is slidably connected to the inner wall of the rod 24, providing elasticity to the locking block 26. Symmetrically arranged locking blocks 26 are slidably connected inside the rod 24, which can be locked into the corresponding slots of the polishing wheel 11 to further fix the polishing wheel 11. The quick-release assembly includes a connecting block 27, which is used to connect the mounting sleeve 22 and the telescopic rod 28. One side of the outer wall is fixedly connected to the other side of the outer wall of the mounting sleeve 22. A telescopic rod 28 is fixedly connected to one side of the outer wall of the connecting block 27. The telescopic rod 28 can extend and retract within a certain range, pushing the polishing wheel 11 to move. A spring 3 29 is sleeved on the outer wall of the telescopic rod 28. The spring 3 29 can make the telescopic rod 28 return to its initial state when no external force is applied, making it easy to eject the polishing wheel 11. A fastening bolt 1 20 is threaded inside the rotating column 15. The fastening bolt 1 20 is used to fix the angle of the limiting wheel 19, ensuring that the limiting wheel 19 is within the angle of the limiting wheel 19. To ensure stability when limiting the pipe fitting and prevent it from rotating arbitrarily and affecting the limiting effect, the rotating rod 8 is internally threaded with a second fastening bolt 30. The second fastening bolt 30 is used to fix the polishing wheel 11, preventing the polishing wheel 11 from loosening during rotation and ensuring its normal operation. The outer wall of the insertion rod 24 is slidably connected to the inside of the polishing wheel 11 to achieve positioning and connection of the polishing wheel 11. One end of the telescopic rod 28 abuts against the outer wall of the polishing wheel 11. The extension and retraction of the telescopic rod 28 pushes the polishing wheel 11 to achieve quick disassembly.
[0030] Working Principle: When the device is needed to polish pipe fittings, it is started by the control panel 2. After starting, the limit wheel 21 moves the pipe fitting. Then, the double-acting screw 12 is rotated to move the threaded sleeve 13, which in turn rotates the rotating plate 14, allowing multiple polishing machines to move and adjust synchronously. Then, the rotating column 15 is rotated to make the limit wheel 19 contact the outer wall of the pipe fitting. The spring 17 extends and retracts to accommodate pipe fittings of different sizes. In addition, for the replacement of the polishing wheel 11, the fastening bolt 20 can be rotated to disengage it from the rotating rod 8. The locking block 26 is pressed to retract the spring 25. Then, under the reaction force of the spring 39, the telescopic rod 28 pushes the polishing wheel 11 to slide on the outer wall of the rotating rod 8. The polishing wheel 11 can be quickly disassembled through the action of the telescopic rod 28 and the spring 39, further improving the practicality of the device.
