Description

Technical Field

[0001] The present invention relates to the field of grinding wheel heads of grinding machines, and particularly to a connecting structure for a grinding wheel head of a grinding machine that is convenient for disassembly. Background Art

[0002] The connecting mechanism of the grinding wheel head of a grinding machine is a device used to connect and fix the grinding wheel head, i.e., the grinding head, in a grinding machine. The design and function of this mechanism are crucial for the stability, precision, and safety of the grinding process. In the field of the connecting structure of the grinding wheel head of a grinding machine in the prior art, for example, a connecting structure for a grinding wheel head of a grinding machine that is convenient for disassembly with the application number 201921656854.X can solve the problem that most of the connections between the grinding wheel of the grinding machine and the main spindle rod adopt threaded covers, or bolts are arranged along the spiral direction of the main spindle rod to fix the flange. The threaded cover requires special tools for disassembly, and there is a possibility of loosening of the threaded cover. And if bolts are arranged along the spiral direction of the main spindle rod, if the grinding wheel is horizontally placed, then the disassembly has to be carried out below the grinding wheel, which is inconvenient for operation. For a grinding wheel that is convenient for installation, it cannot perform angular adjustment work in the circumferential direction following the rotating rod. In addition, the inclined grinding wheel plays an important role in machining the square lamp housing frame. The trapezoidal surface design of the end face of the lamp housing frame helps to enhance the structural strength of the lamp housing frame and also has a unique visual effect, which can increase the three-dimensional sense and layering of the lamp. However, the existing grinding wheel is difficult to adapt to the slope for grinding after installation and can only be ground manually with a grinding machine, which is quite laborious.

[0032] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0033] As Figures 1-13 shown, a connection structure between a grinding wheel and a grinding head of a grinding machine that is convenient for disassembly includes a support frame 1 and a base I 9 fixedly connected to the left side of the surface of the support frame 1. A rotating frame 6 is rotatably connected to the upper side of the base I 9. A rotating rod 7 is rotatably connected to the right side of the rotating frame 6. The left side of the rotating rod 7 is fixedly connected to the output shaft of a motor I 8 through a coupling. The motor I 8 is fixedly connected to the rotating frame 6. The right side of the rotating rod 7 is inserted with a grinding head 16, and a grinding wheel 15 is provided on the grinding head 16;

[0034] A base II 12 is fixedly connected to the upper side of the support frame 1. A side seat 13 is fixedly connected to the bottom right side of the rotating frame 6. A convex seat 10 is rotatably connected to the front and rear sides of the base II 12 and the front and rear sides of the side seat 13 respectively. A hydraulic cylinder 11 is fixedly connected between the two convex seats 10 on the front side. Another hydraulic cylinder 11 is fixedly connected between the two convex seats 10 on the rear side. The movable ends of the two hydraulic cylinders 11 are fixedly connected to the two convex seats 10 on the upper side. The fixed ends of the two hydraulic cylinders 11 are fixedly connected to the two convex seats 10 on the lower side. It should be noted that the working states of the two hydraulic cylinders 11 always remain synchronized.

[0035] Holes are uniformly provided in the circumferential direction of the middle parts of the grinding head 16 and the grinding wheel 15 in a one-to-one correspondence. A bolt assembly 17 is installed in each hole so that the grinding wheel 15 is installed on the grinding head 16.

[0036] On the left side of the middle part of the support frame 1, a concave frame 4 is fixedly connected, and a limit seat 5 is fixedly connected to the lower side of the middle part of the concave frame 4. It is used to limit the upward rotation amplitude of the rotating frame 6.

[0037] The middle part of the limit seat 5 is a semi-circular groove, and the semi-circular groove can be in contact and fit with the top of the right side of the rotating frame 6. It can better adapt to limit the end position of the rotating frame 6.

[0038] At the four corners of the middle part of the support frame 1, a side position frame 2 is fixedly connected respectively. The two ends of a lead screw 19 are rotatably connected to the front two side position frames 2, and the two ends of another lead screw 19 are rotatably connected to the rear two side position frames 2. The output shaft of a motor II 20 is fixedly connected to the right side of the front lead screw 19 through a coupling. The motor II 20 is fixedly connected to the machine base 3 through bolts, and the machine base 3 is fixedly connected to the side position frame 2 located at the right front side. A cross-moving seat 18 is driven and connected on the two lead screws 19. A limit rod 26 is fixedly connected to the bottom of the middle part of the cross-moving seat 18. A top seat 24 is rotatably connected to the front and rear sides of the limit rod 26 respectively. A linkage seat 23 is slidably connected to each top seat 24. The two linkage seats 23 are rotatably connected to the front and rear sides of the driving ring 36 respectively. The middle part of the driving ring 36 is embedded and rotatably connected to the outside of the grinding head 16. A pulley 21 is fixedly connected to the left side of each of the two lead screws 19, and the two pulleys 21 are driven and connected through a belt 22. When the motor II 20 operates, the two lead screws 19 can rotate synchronously through the belt 22, thereby ensuring the stability of the two ends of the cross-moving seat 18 during movement and preventing problems such as being stuck due to non-synchronization.

[0039] A spring 25 is sleeved on each side of each linkage seat 23, and the two sides of each spring 25 are in contact with the adjacent sides of the two linkage seats 23 and the two top seats 24 respectively. Each spring 25 is a tension spring. It plays a pulling role to ensure that the pulling force can make the driving ring 36 pull and limit the grinding head 16, avoiding the grinding head 16 falling off the rotating rod 7 due to gravity.

[0040] Two fixing holes 14 are respectively provided on the front and rear sides of the support frame 1. A plug rod 28 is fixedly connected in each fixing hole 14. The outer sides of the four plug rods 28 are fixedly connected to the bottom of the protective frame 27. A sliding bar 29 is fixedly connected to the front and rear sides of the bottom of the protective frame 27. The front and rear sides of a cross frame 30 are slidably connected to the two sliding bars 29 respectively. A clamping seat I 31 is fixedly connected to the upper side of the middle part of the cross frame 30. A support 32 is slidably connected to the right side of the middle part of the cross frame 30. A clamping seat II 33 is fixedly connected to the upper side of the support 32. The movable end of an electric push rod 34 is fixedly connected to the middle part of the support 32, and the fixed end of the electric push rod 34 is fixedly connected to the middle part of the cross frame 30. This part of the design is used to fix the cylindrical lamp frame 37 and control the cylindrical lamp frame 37 to approach the grinding head 16.

[0041] An arc-shaped plastic transparent plate 35 is fixedly installed on the upper side of the protective frame 27, which plays a protective role.

[0042] To facilitate the provision of a grinding wheel grinding head connection structure with a convenient disassembly 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 inserted into the right side of the rotating rod 7 through the meshing hole in the middle thereof. A plurality of grooves are provided on the right side of the rotating rod 7 along the circumferential direction, and a plurality of ridges meshing with the grooves on the right side of the rotating rod 7 are uniformly provided along the circumferential direction in the meshing hole in the middle of the grinding head 16. Thus, the grinding head 16 can be directly inserted into the right side of the rotating rod 7 to perform synchronous rotation work with the rotating rod 7, so that the grinding head 16 can drive the grinding wheel 15 to be disassembled and installed from the rotating rod 7 at any time. The structure is simple and the installation is convenient. When the rotating rod 7 rotates, the driving motor I 8 causes the rotating rod 7 to rotate, so that the rotating rod 7 can drive the grinding head 16 and the grinding wheel 15 located on the grinding head 16 to rotate through the meshing between the grooves and the ridges, and thus the grinding wheel 15 can perform grinding work on the workpiece to be ground;

[0043] When limiting the grinding head 16 and enabling the grinding head 16 to be inserted onto the rotating rod 7, the driving motor II 20 is activated 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 synchronously rotated by using the belt pulley 21 and the belt 22. When the two lead screws 19 rotate synchronously, the cross-slide 18 moves horizontally, driving the drive ring 36 rotatably connected by the two linkage seats 23 below the limiting rod 26 to move horizontally. Synchronously, the drive ring 36 drives the grinding head 16 to move horizontally. When the middle part of the grinding head 16 is about to reach the right side position of the rotating rod 7, the grinding head 16 is manually rotated to rotate within the drive ring 36, so that the hole in the middle of the grinding head 16 is docked and installed with the rotating rod 7, facilitating the installation work of larger grinding heads 16 or heavier grinding heads 16 and grinding wheels 15 to avoid manual installation steps and reduce the labor intensity of the staff. The four springs 25 on both sides have a certain elastic coefficient selected by the staff, so they will not undergo large elastic deformations. Therefore, the drive ring 36 can drive the grinding head 16 to move horizontally, and thus will not have a large vertical displacement. Therefore, it is convenient for the grinding head 16 to be aligned and installed onto the rotating rod 7;

[0044] The grinding wheel 15 that is convenient for installation can follow the rotating rod 7 to perform angular adjustment work in the circumferential direction, which helps to perform adaptive grinding work on the lamp holder frame 37 at different angles. During use, two hydraulic cylinders 11 are driven simultaneously to cause the hydraulic cylinders 11 to contract adaptively. Then, the flipping frame 6 rotates and adjusts the angle on the base I 9. Therefore, the motor I 8 located on the flipping frame 6, the synchronous rotating rod 7, the grinding wheel 15 and the grinding head 16 on the rotating rod 7 rotate and adjust the angle. The grinding wheel 15 that is convenient for installation can follow the rotating rod 7 to perform angular adjustment work in the circumferential direction, which helps to perform adaptive grinding work on the lamp holder frame 37 at different angles. And synchronously, the grinding head 16 is used to pull down the driving ring 36, and the two linkage seats 23 are pulled through the driving ring 36, so that the two linkage seats 23 stretch the springs 25 thereon. The springs 25 on both sides provide an upward restoring force for the driving ring 36 and the grinding wheel 15 and the grinding head 16 located in the middle of the driving ring 36. The state at this time is as shown in Figure 12 shown in the figure. The structure of this solution is simple, suitable for the device to deform and quickly restore its original position. When the flipping frame 6 restores its original position, the top on the right side of the flipping frame 6 flips upward. Then, the top on the right side of the flipping frame 6 can fit into the semi-circular groove in the middle of the limit seat 5 to limit the flipping frame 6 and make the flipping frame 6 restore to the horizontal state;

[0045] When grinding the workpiece to be ground, the electric push rod 34 is driven to make the clamping seat II 33 move towards the clamping seat I 31. Then, the lower half part of the lamp holder frame 37 is clamped by the clamping seat I 31 and the clamping seat II 33. After that, the cross frame 30 moves horizontally on the two horizontal moving sliding strips 29, driving the clamped lamp holder frame 37 close to the rotating grinding wheel 15 for grinding work. A plastic transparent plate 35 is installed on the upper side of the protective frame 27 to prevent the impurities caused by grinding from splashing and protect the nearby workers.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
