Description

Technical Field

[0001] The invention relates to the field of grinding wheels for grinding machines, and in particular to a grinding wheel and grinding head connection structure for grinding machines which is easy to disassemble. Background Art

[0002] The grinding wheel and grinding head connecting mechanism of a grinding machine is a device used to connect and fix the grinding wheel and grinding head in a grinding machine. The design and function of this mechanism are crucial to the stability, precision and safety of the grinding process. In the field of grinding wheel and grinding head connection structures of the prior art, for example, an easily disassembled grinding wheel and grinding head connection structure with application number 201921656854.X can solve the problem that the grinding wheel and the main shaft rod are mostly connected by a threaded cover plate, or a bolt fixing flange is set along the screw direction of the main shaft rod. The threaded cover plate requires special tools for disassembly, and the threaded cover plate is likely to loosen. Bolts are set along the screw direction of the main shaft rod. If the grinding wheel is horizontally placed, then the disassembly must be located below the grinding wheel, which is inconvenient to operate. For the grinding wheel that is easy to install, it cannot follow the rotating rod to adjust the angle in the circumferential direction; in addition, the inclined grinding wheel plays an important role in processing the square downlight frame. The trapezoidal surface design of the end face of the downlight frame helps to enhance the structural strength of the downlight frame, and also has a unique visual effect, which can increase the three-dimensional sense and layering of the downlight. However, the existing grinding wheel is difficult to adapt to the slope for grinding after installation, and can only be polished manually using a grinder, which is more laborious.

It should be noted that the working states of the two hydraulic cylinders 11 are always kept synchronous.

[0018] The grinding head 16 and the grinding wheel 15 are evenly provided with holes corresponding to each other in the circumferential direction of the middle part, and a bolt assembly 17 is installed in each hole so that the grinding wheel 15 is installed on the grinding head 16.

[0019] A concave frame 4 is fixedly connected to the left side of the middle of the support frame 1, and a limit seat 5 is fixedly connected to the lower side of the middle of the concave frame 4 to limit the range of the upward rotation of the rotating frame 6.

[0020] The middle part of the limiting seat 5 is a semicircular groove, and the semicircular groove can be in contact with the top of the right side of the rotating frame 6. It can better adapt to the end position of the rotating frame 6 for limiting.

[0021] A side frame 2 is fixedly connected to the four corners of the middle part of the support frame 1, and the two side frames 2 on the front sides are rotatably connected to the two ends of a lead screw 19, and the two side frames 2 on the rear sides are rotatably connected to the two ends of another lead screw 19. The right side of the front lead screw 19 is fixedly connected to the output shaft of the motor Ⅱ 20 through a coupling, and the motor Ⅱ 20 is fixedly connected to the machine base 3 by bolts, and the machine base 3 is fixedly connected to the side frame 2 located on the right front side.

When the motor II 20 is running, the two screw rods 19 can rotate synchronously through the belt 22, thereby ensuring the stability of the positions of the two ends of the transverse shift seat 18 when it moves, and preventing the problem of being stuck due to asynchronism.

[0022] A spring 25 is sleeved on both sides of each linkage seat 23, and both sides of each spring 25 are in contact with the two linkage seats 23 and the adjacent sides of the two top seats 24. Each spring 25 is a tension spring, which plays a pulling role, ensuring that the pulling force can make the driving ring 36 pull the limited grinding head 16, so as to prevent the grinding head 16 from being separated from the rotating rod 7 due to gravity.

[0023] Two fixing holes 14 are respectively provided on the front and rear sides of the support frame 1, and a plug rod 28 is fixedly connected in each fixing hole 14. The outer sides of the four plug rods 28 are respectively fixedly connected to the bottom of the protective frame 27. A sliding bar 29 is respectively fixedly connected to the front and rear sides of the bottom of the protective frame 27. The two sliding bars 29 are respectively slidably connected to the front and rear sides of the cross frame 30. A clamping seat I 31 is fixedly connected to the upper side of the middle of the cross frame 30. A bracket 32 ​​is slidably connected to the right side of the middle of the cross frame 30. A clamping seat II 33 is fixedly connected to the upper side of the bracket 32. The movable end of the electric push rod 34 is fixedly connected to the middle of the bracket 32. The fixed end of the electric push rod 34 is fixedly connected to the middle of the cross frame 30. This part is designed to fix the downlight frame 37 and control the downlight frame 37 to approach the grinding head 16.

[0024] The upper side of the protection frame 27 is fixedly provided with an arc-shaped plastic transparent plate 35, which plays a protective role.

[0025] In order to provide a grinding wheel and grinding head connection structure for a grinding machine with an easy-to-disassemble function, during installation and disassembly, the grinding wheel 15 is fixedly connected to the grinding head 16 through a plurality of bolt assemblies 17, and the grinding head 16 is installed and inserted into the right side of the rotating rod 7 through the meshing hole in the middle thereof. The right side of the rotating rod 7 is provided with a plurality of grooves along the circumferential direction, and the meshing hole in the middle of the grinding head 16 is evenly provided with a plurality of convex strips meshing with the grooves on the right side of the rotating rod 7 along the circumferential direction, so that the grinding head 16 can be directly inserted into the right side of the rotating rod 7 and rotate synchronously with the rotating rod 7, so that the grinding head 16 can be removed and installed from the rotating rod 7 at any time with the grinding wheel 15, the structure is simple and the installation is convenient, and when the rotating rod 7 rotates, the driving motor I8 makes the rotating rod 7 rotate, so that the rotating rod 7 can drive the grinding head 16 and the grinding wheel 15 on the grinding head 16 to rotate through the meshing between the grooves and the convex strips, so that the grinding wheel 15 can grind the grinding workpiece; The grinding head 16 is limited and when the grinding head 16 is inserted into the rotating rod 7, the motor II 20 is driven to rotate the lead screw 19. When the lead screw 19 at the front side rotates, the lead screw 19 at the rear side is rotated synchronously by the pulley 21 and the belt 22. When the two lead screws 19 rotate synchronously, the transverse seat 18 moves laterally, driving the driving ring 36 rotatably connected by the two linkage seats 23 below the limit rod 26 to move laterally. Synchronously, the driving ring 36 drives the grinding head 16 to move laterally, so that when the middle part of the grinding head 16 is about to reach the right side of the rotating rod 7, the grinding head 16 is moved by a person. The rotating grinding head 16 rotates in the driving ring 36, so that the hole in the middle of the grinding head 16 is docked with the rotating rod 7 for installation, which is convenient for a larger grinding head 16 or a heavier grinding head 16 and a grinding wheel 15 to avoid the manual installation steps, reducing the fatigue of the staff, and the four springs 25 on both sides have a certain elastic coefficient through the selection of the staff, so that no large elastic deformation will occur, so the driving ring 36 can drive the grinding head 16 to move horizontally, so that no large vertical displacement will occur, so it is convenient to align the grinding head 16 and install it on the rotating rod 7; The grinding wheel 15 for easy installation can follow the rotating rod 7 to adjust the angle in the circumferential direction, which is helpful for adaptive grinding of the downlight frames 37 at different angles. When in use, the two hydraulic cylinders 11 are driven at the same time to make the hydraulic cylinder 11 contract adaptively, and then the flip frame 6 is rotated and adjusted on the base Ⅰ9. Therefore, the motor Ⅰ8 on the flip frame 6 synchronizes the rotating rod 7 and the grinding wheel 15 and the grinding head 16 on the rotating rod 7 to rotate and adjust the angle. The grinding wheel 15 for easy installation can follow the rotating rod 7 to adjust the angle in the circumferential direction, which is helpful for adaptive grinding of the downlight frames 37 at different angles, and the grinding head 16 is used to pull the driving ring 36 downward synchronously, and the two linkage seats 23 are pulled by the driving ring 36, so that the two linkage seats 23 stretch the springs 25 thereon, and the springs 25 on both sides provide the driving ring 36 and the grinding wheel 15 and the grinding head 16 located in the middle of the driving ring 36 with a force to restore the original position upward. At this time, the state is as follows Fig.12 The scheme is simple in structure and suitable for the device to deform and quickly restore to its original position. When the flip frame 6 is restored to its original position, the top of the right side of the flip frame 6 is flipped upward, and then the top of the right side of the flip frame 6 can be fitted into the semicircular groove in the middle of the limit seat 5, so that the flip frame 6 is limited, so that the flip frame 6 is restored to a horizontal state; When the polishing work is being carried out on the polishing workpiece, the electric push rod 34 is driven to make the clamping seat II 33 move toward the clamping seat I 31, and then the lower half of the downlight frame 37 is clamped by the clamping seat I 31 and the clamping seat II 33, and then the cross frame 30 is moved laterally on the two horizontal moving sliding bars 29, driving the clamped downlight frame 37 to approach the rotating grinding wheel 15 for polishing, and a plastic transparent plate 35 is installed on the upper side of the protective frame 27 to facilitate the splashing of impurities caused by grinding to protect the staff nearby.
