[0002] A double-disc surface grinder is a highly efficient surface machining machine primarily used for precision grinding of parallel workpiece end surfaces. It can simultaneously grind two parallel workpiece end surfaces in a single process. The operating principle of a double-disc surface grinder is to use two grinding heads to simultaneously grind both sides of the workpiece, achieving precision machining with guaranteed parallelism, dimensional accuracy, and surface quality. During machining, the workpiece is clamped between the two grinding heads, where it undergoes reciprocating motion while being ground. The grinding heads of double-disc surface grinders can become damaged during use, necessitating periodic replacement. However, this requires the machine to be shut down during replacement, making the speed of head replacement crucial to production efficiency. Therefore, to ensure high production efficiency, a double-disc surface grinder with a fast-changing grinding head is required. Utility Model Content

[0021] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6As shown, a double-end surface grinder with a quickly replaceable grinding head comprises a workbench 1 and a grinding wheel 10. A driving assembly 2 is fixedly mounted on the upper end of the workbench 1, two movable platforms 3 are mounted on the driving assembly 2, a motor 4 is fixedly mounted on the upper end of the movable platform 3, two brackets 8 are symmetrically fixedly mounted on the upper end of the workbench 1 and on both sides of the driving assembly 2, an operating table 9 is fixedly mounted on the upper ends of the two brackets 8 and above the driving assembly 2, a fixing assembly 5 is fixedly mounted on the output shaft of the motor 4, and the fixing assembly 5 consists of a threaded rod 11, a mounting plate 12, a connecting plate 13, an L-shaped frame 15, an insertion rod 17, a fixing ring 18 and a disassembly spring 19. The mounting plate 12 is fixedly mounted on the outer end of the threaded rod 11, the connecting plate 13 is fixedly mounted on the inner end of the threaded rod 11, there are four L-shaped frames 15 and they are symmetrically fixedly mounted on the outer end of the connecting plate 13, there are four insertion rods 17 and they are respectively movably inserted on the four L-shaped frames 15, and there are four fixing rings 18 and they are respectively fixedly sleeved on the four insertion rods 17, and the fixing ring 18 is located on the inner side of the L-shaped frame 15, there are four disassembly springs 19 and they are respectively sleeved on the four insertion rods 17, the disassembly spring 19 is located between the L-shaped frame 15 and the fixing ring 18, a connecting assembly 6 is inserted on the connecting plate 13, the connecting assembly 6 is composed of a base plate 20 and an arc plate 21, there are four arc plates 21 and they are symmetrically fixedly installed on the outer end of the base plate 20, the grinding wheel 10 is fixedly sleeved on the base plate 20, a limit assembly 7 is installed on the threaded rod 11, the limit assembly 7 is composed of a threaded cylinder 24 and a rotating ring 25, the rotating ring 25 is fixedly sleeved on the threaded cylinder 24, the operating table 9 is located between the two mobile platforms 3, when grinding the workpiece, the clamp can be used to fix the workpiece on the mobile platform 3, and then the driving assembly 2 can be started, so that the two mobile platforms 3 bring the two motors 4 close to each other, and the motor 4 is started at the same time, thereby driving the grinding wheel 10 to rotate at high speed, and finally making the high-speed rotating grinding wheel 10 contact with the end face of the workpiece, thereby grinding the workpiece;When the grinding wheel 10 needs to be replaced, the limit assembly 7 can be rotated on the threaded rod 11, so that the threaded cylinder 24 is moved out from the inner side of the four insertion rods 17. At this time, the insertion rod 17 that has lost the obstruction of the threaded cylinder 24 will be pushed inward by the disassembly spring 19, and then the insertion rod 17 will be moved out of the insertion hole 22. At this time, the fixation of the connecting assembly 6 and the grinding wheel 10 is released, and then the grinding wheel 10 and the connecting assembly 6 can be pulled to move the arc plate 21 out of the arc groove 14. At this time, the disassembly of the grinding wheel 10 is completed, and then the new grinding wheel 10 and the connecting assembly 6 can be installed and fixed to the fixing assembly 5. The method is to first insert the arc plate 21 on the connecting assembly 6 into the arc groove 14 from the inside to the outside, and finally until the base plate 20 contacts the inner end of the connecting plate 13. At this time, the socket 22 and the insertion rod 17 will be coaxial. Then the limit assembly 7 can be rotated, so that the threaded barrel 24 moves toward the inside of the four insertion rods 17. During this process, the threaded barrel 24 will contact and squeeze the insertion rod 17, so that the insertion rod 17 will move into the socket 22. At this time, the disassembly spring 19 will be compressed by the fixing ring 18. When the insertion rod 17 is inserted into the socket 22, the grinding wheel 10 and the connecting assembly 6 will be fixed. At this time, the replacement of the grinding wheel 10 is completed. Finally, the fixing assembly 5, the connecting assembly 6 and the limit assembly 7 cooperate to make the disassembly and assembly steps of the grinding wheel 10 relatively simple, thereby making the disassembly and assembly of the grinding wheel 10 more efficient, thereby shortening the downtime of the double-end surface grinder, and ultimately ensuring that the double-end surface grinder has a higher production efficiency.

When the limit assembly 7 is moved to the inside of the four insertion rods 17 and the limit assembly 7 is rotated on the threaded rod 11, the limit assembly 7 will move outward or inward. When the grinding wheel 10 and the connecting assembly 6 need to be removed, the limit assembly 7 can be moved outward. Conversely, when the grinding wheel 10 and the connecting assembly 6 need to be fixed, the limit assembly 7 can be moved inward; when the insertion rod 17 on the fixing assembly 5 is squeezed by the threaded cylinder 24, the insertion rod 17 will move with the fixing ring 18. At this time, the disassembly spring 19 will be compressed by the fixing ring 18. When the insertion rod 17 is inserted into the socket 22, the connecting assembly 6 and the grinding wheel 10 will be fixed on the fixing assembly 5. When the obstruction of the threaded cylinder 24 is lost, the fixing ring 18 and the insertion rod 17 will be pushed inward under the elastic force of the disassembly spring 19, so that the insertion rod 17 will be removed from the socket 22. At this time, the fixation of the connecting assembly 6 and the grinding wheel 10 will be released.
