Description

Technical Field

[0001] The utility model relates to the technical field of a main shaft support seat, in particular to a support component for supporting a central rotating shaft. Background Art

[0002] Motor drive is a very common power source in mechanical products. The use of motors is generally combined with a large number of rotating shafts to transmit power. The rotating shaft, as the name implies, is a shaft that must be used to connect the main parts of the product and is used to withstand both bending moments and torques during rotation. The installation of the rotating shaft requires the use of a corresponding support seat, and for the central rotating shaft, a suitable support seat is even more needed to ensure the normal operation of the rotating shaft. For the longitudinally distributed rotating shaft, the rotating shaft will be affected by gravity and try to move in its axial direction, which leads to the risk of slippage between it and the bearing. In view of this, in-depth research was conducted on the above-mentioned issues, which led to the creation of this case. Utility Model Content

[0003] The purpose of the present invention is to provide a support assembly for supporting a central rotating shaft, so as to solve the problem of slippage easily occurring between the longitudinal rotating shaft and the bearing proposed in the above background technology.

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.

[0020] Example: See Figure 1-4 A support assembly for supporting a central rotating shaft includes a base 5, a cavity 7 is defined within the base 5, and a spindle body 3 is longitudinally penetrated within the base 5, a fixed disk 10 is welded to the outer wall of the spindle body 3 within the cavity 7, and the outer wall of the fixed disk 10 is fixed to the inner wall of the cavity 7 through a bearing, two annular grooves 14 are defined at the upper and lower ends of the fixed disk 10, and a plurality of balls 9 are embedded at the upper and lower ends of the cavity 7, and one end of each ball 9 extends into the interior of the annular groove 14;

[0021] Specifically, such as Figure 1 and Figure 3 As shown, the ball 9 cooperates with the fixed plate 10, and the friction between the two is very small, which can ensure the smooth rotation of the main shaft body 3. At the same time, the ball 9 supports and limits the fixed plate 10 to prevent the main shaft body 3 from axial movement. In addition, such a design can also prevent the main shaft body 3 from tilting to a certain extent, and can better enable the longitudinally installed main shaft body 3 to participate in the work.

[0022] The top of the outer wall of the main shaft body 3 is provided with a plurality of grooves 2, and the tops of the grooves 2 extend to the top of the main shaft body 3. The outer wall of the main shaft body 3 is provided with a detachable support 1, and the inner wall of the detachable support 1 is provided with a rotating ring 12 through a bearing, and the inner wall of the rotating ring 12 is fixed with a plurality of ridges 13;

[0023] The cross-sectional shape, size and number of the ridges 13 and the grooves 2 are the same, and the ridges 13 extend into the interior of the grooves 2;

[0024] A mounting base 4 is fixed to one side of the detachable support 1 and the base 5;

[0025] Specifically, such as Figure 1 and Figure 2 As shown. Place the detachable support 1 above the main spindle body 3 and move it downward so that the ridges 13 fit into the grooves 2. Now place the main spindle body 3 horizontally and use the detachable support 1 and the mounting base 4 on the base 5 to fix the position. The installation direction of the main spindle body 3 can be changed to adapt it to different installation positions. The detachable support 1 can also participate in supporting the main spindle body 3.

[0026] Four fixing rods 6 are fixed to the bottom end of the base 5, and the bottom ends of the fixing rods 6 are fixed with fixing columns 16. The bottom ends of the outer walls of the fixing columns 16 are installed with rotating sleeves 17, and the outer walls of the fixing columns 16 above the rotating sleeves 17 are sleeved with movable cylinders 19. A connecting rod 8 is fixed to one side of the movable cylinder 19, and the bottom ends of the connecting rods 8 are fixed with mounting legs 11; the bottom ends of the outer walls of the fixing columns 16 are provided with external threads, and the inner walls of the rotating sleeves 17 are provided with internal threads matching them;

[0027] The bottom end of the outer wall of the fixing rod 6 is provided with a plurality of positioning grooves 15, and the top end of the fixing column 16 is fixed with a corresponding number of positioning plates 18 that match it, and the top end of the positioning plates 18 extends into the interior of the corresponding positioning grooves 15;

[0028] Specifically, such as Figure 1 and Figure 4 As shown, when the main shaft body 3 is installed longitudinally, the mounting foot 11 extends toward the outside of the base 5, and the mounting foot 11 is fixed to the corresponding mounting position. When the main shaft body 3 is installed horizontally, in order to prevent it from blocking the installation of the mounting seat 4, the rotating sleeve 17 can be rotated to remove, and then the movable cylinder 19 is moved to separate the positioning plate 18 and the positioning groove 15. After the movable cylinder 19 is rotated to a certain angle, the positioning plate 18 is inserted into the positioning groove 15, and then the rotating sleeve 17 is tightened on the outer wall of the fixed column 16. In this way, the movable cylinder 19 cannot move along the fixed column 16 or rotate, and the mounting foot 11 can be rotated to the appropriate position and retracted.
