Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example (b): a rotating shaft structure convenient for replacing a grinding wheel is shown in figure 1 and comprises a mounting shaft 1, a clamping disc 2 and an auxiliary rotating structure 3. The mounting shaft 1 is rotatably connected to a grinding wheel 14 rack (not shown in the figure), and a driving motor (not shown in the figure) drives the mounting shaft 1 to rotate. The coaxial fixedly connected with of installation axle 1 touches dish 4, joint dish 2 and installation axle 1 threaded connection. The grinding wheel 14 is coaxially sleeved on the mounting shaft 1, and then the opposite side walls of the clamping disc 2 and the abutting disc 4 are respectively attached to the end surfaces opposite to the grinding wheel 14, so that the grinding wheel 14 is fixed. The auxiliary rotating structure 3 can drive the clamping disc 2 and the mounting shaft 1 to rotate in the direction, so that the grinding wheel 14 is more convenient to replace.
As shown in fig. 2, four locking levers 5 are fixedly connected to the side wall of the end of the interference plate 4 close to the chuck 2 in the circumferential direction, and the four locking levers 5 penetrate through the grinding wheel 14 to provide a rotating torque for the grinding wheel 14. When the thickness of the grinding wheel 14 is smaller than the length of the locking lever 5, the chuck 2 cannot hold the grinding wheel 14 tightly. For this purpose, an annular recess 6 is formed in an end of the card disk 2 facing the contact disk 4, and an end of the locking lever 5 remote from the contact disk 4 penetrates the recess 6. A plurality of anti-skidding grooves 15 are formed in the end face, facing the end face of the contact disc 4, of the clamping disc 2, friction force between the clamping disc 2 and the grinding wheel 14 is increased, the clamping disc 2 is locked through the friction force, and the rotating shaft structure is stable.
As shown in fig. 2 and 3, the auxiliary rotating structure 3 includes a hinge shaft 7, a first lever 8, and a second lever 9. The hinge shaft 7 is hinged at the center of the end surface of the mounting shaft 1, and the hinge axis between the hinge shaft 7 and the mounting shaft 1 is perpendicular to the mounting shaft 1. The length of the hinge shaft 7 is smaller than the radius of the mounting shaft 1. 7 terminal surface fixedly connected with of articulated shaft is outstanding connecting block 10, 8 one end of first lever set up rather than the mounting groove 11 of adaptation, and connecting block 10 pegs graft in mounting groove 11, and 8 one end of first lever are worn to be equipped with axis of rotation 12 perpendicularly, and axis of rotation 12 passes connecting block 10 perpendicularly and both rotate and connect. The second lever 9 is sleeved on the hinge shaft 7 and is rotatably connected with the hinge shaft. The first lever 8 and the second lever 9 are equal in length and diameter.
As shown in fig. 2 and fig. 3, a clamping groove 13 is circumferentially formed at one end of the clamping disc 2 away from the contact disc 4, and the second lever 9 is clamped in the clamping groove 13. The second lever 9 is clamped in one clamping groove 13, and the clamping disc 2 can be driven to rotate when the second lever 9 is rotated. The first lever 8 and the second lever 9 are utilized to respectively drive the mounting shaft 1 and the clamping disc 2 to rotate in opposite directions, so that the mounting shaft 1 and the clamping disc 2 are locked or disassembled, and the grinding wheel 14 is more convenient to replace. After the installation is accomplished, with second lever 9 joint in the draw-in groove 13 of keeping away from first lever 8, make pivot structure's focus be located the axis of rotation department of installation axle 1, it is more stable when making pivot structure rotate, reduce the vibration. First lever 8 rotates and also blocks in draw-in groove 13 to prevent that joint dish 2 from installing the axle 1 rotation relatively, make joint dish 2 and installation axle 1's connection structure more stable.
The specific working mode of the embodiment is as follows: the first lever 8 is taken out of the clamping groove 13, the second lever 9 is clamped in the clamping groove 13, and then the mounting shaft 1 and the clamping disc 2 are driven to rotate in the opposite directions by the first lever 8 and the second lever 9 respectively. The hinge shaft 7 is rotated so that the hinge shaft 7, the first lever 8 and the second lever 9 are all parallel to the mounting shaft 1, and then the chuck 2 and the grinding wheel 14 are removed from the mounting shaft 1 and replaced with a new grinding wheel 14. The clamping disc 2 is connected to the mounting shaft 1 in a threaded mode, then the second lever 9 is clamped in the clamping groove 13 again, and then the mounting shaft 1 and the clamping disc 2 are driven to rotate in the opposite direction respectively by the first lever 8 and the second lever 9, so that the mounting shaft 1 and the clamping disc 2 are locked.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
