Detailed Description of the Embodiment

[0021] The technical solutions in the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely examples, and the present utility model is not limited to the various structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0022] Referring to Figures 1-4 , the present utility model provides a throttle bearing assembly mechanism, including a base 1 and a carrier table 12. The upper surface of the base 1 is fixedly connected to a bottom plate 2 by bolts. The upper surface of the bottom plate 2 is fixedly connected to two connecting rods 3 by bolts. The tops of the two connecting rods 3 are fixedly connected to a top plate 4 by bolts. The upper surface of the top plate 4 is fixedly connected to a cylinder 5 by bolts. One end of the output shaft of the cylinder 5 passes through the lower surface of the top plate 4 and is fixedly connected to a connecting plate 6 by bolts. A threaded groove 9 is formed in the lower surface of the connecting plate 6. A threaded rod 10 is threadedly connected in the threaded groove 9. One end of the threaded rod 10 is welded to a pressing plate 11. A groove 18 is formed in the lower surface of the carrier table 12. A convex platform 7 is fixedly connected to the upper surface of the bottom plate 2 by bolts. The top end of the convex platform 7 is inserted into the groove 18 and a clamping assembly is provided between the convex platform 7 and the groove 18. By setting the pressing plate 11 and the connecting plate 6 to be detachable, it is convenient for the staff to replace the pressing plate 11 after it is damaged during long-term operation. Through the mutual cooperation of the threaded rod 10 and the threaded groove 9, it can be replaced in a more rapid manner, and the structure is simple and easy to operate.

[0023] Among them, the engaging component is two avoidance grooves 19, both of which are opened in the boss 7. A square plate 17 is slidably connected in each of the two avoidance grooves 19. A round rod 14 is welded to one side of the square plate 17, and the round rod 14 passes through the circumferential outer wall of the lower half of the boss 7 and is slidably connected to the boss 7. Two clamping grooves 21 are opened on the circumferential inner wall of the groove 18. A clamping rod 20 is welded to the same side of the square plate 17, and one end of the clamping rod 20 passes through the circumferential outer wall of the upper half of the boss 7 and is inserted into the clamping groove 21. By providing the engaging component, the boss 7 and the bearing platform 12 are set to be detachable. After the upper surface of the bearing platform 12 is worn, the bearing platform 12 can be removed, which is convenient for the staff to quickly replace the bearing platform 12. A spring 16 is welded to one side of the square plate 17, and the other end of the spring 16 is fixed to the inner wall of one side of the avoidance groove 19. By providing the spring 16, an elastic force can be applied to the square plate 17, so that it is always located on one side of the avoidance groove 19. At the same time, the clamping rod 20 can be tightly inserted into the clamping groove 21 to prevent the clamping rod 20 from disengaging from the clamping groove 21 due to vibration, resulting in the detachment of the bearing platform 12 and the inability of the device to work. Two sliding rods 8 are fixedly connected to the upper surface of the connecting plate 6 by bolts, and the tops of the two sliding rods 8 both pass through the top plate 4 and are slidably connected to the top plate 4. By providing the sliding rods 8, the connecting plate 6 can be guided during the up and down movement to prevent deviation. One ends of the two round rods 14 are both fixedly connected to a pressing head 15 by bolts. The surface of the pressing head 15 is provided with anti-slip lines. By providing the pressing head 15, it is convenient for the staff to operate the round rod 14. The anti-slip lines can increase the friction force on the surface of the pressing head 15. A round plate 13 is provided on the upper surface of the bearing platform 12, and the round plate 13 is made of cemented carbide. By providing the round plate 13, the hardness of the surface of the bearing platform 12 can be increased, so that the service life of the bearing platform 12 is greatly increased. The tops of the two sliding rods 8 are both fixedly connected to a limit block by bolts. By providing the limit block, it can prevent the cylinder 5 from extending excessively and causing the sliding rod 8 to disengage from the top plate 4. Four corners of the lower surface of the base 1 are all fixedly connected to support legs by bolts, and rubber blocks are bonded to the bottoms of the multiple support legs. By providing the support legs, the device can be separated from the tabletop.

[0024] When the present utility model is in use, it is divided into the following steps:

[0025] S1: First, when the pressing plate 11 needs to be replaced, rotate the pressing plate 11. The rotation of the pressing plate 11 drives the threaded rod 10 to rotate. While the threaded rod 10 rotates in the threaded groove 9, it drives the threaded rod 10 to gradually move downward. Continue to rotate the pressing plate 11 until the threaded rod 10 is completely disengaged from the threaded groove 9, and the pressing plate 11 can be replaced;

[0026] S2: When it is necessary to replace the carrier 12, press both pressing heads 15 simultaneously, driving the two round rods 14 to move in the same direction. When the round rods 14 move, they drive the square plate 17 to move along the avoidance groove 19, while squeezing the spring 16 to make the spring 16 continuously stressed. The sliding of the square plate 17 drives the latch 20 to move. When the latch 20 is completely disengaged from the card slot 21, the carrier 12 can be removed. After placing a new carrier 12, release the pressing head 15. The spring 16 releases its elastic force to push the square plate 17 to move, thereby driving the latch 20 to move. When the latch 20 is completely inserted into the card slot 21, the replacement is completed;

[0027] S3: When it is necessary to continue assembling the bearing, place the workpiece on the upper surface of the carrier 12, and start the cylinder 5 to drive the connecting plate 6 to move and at the same time move the pressing plate 11 downward to process the workpiece.

[0028] Finally, the following points should be noted: In the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the internal communication of two components, and can be directly connected. The terms "upper", "lower", "left", "right", etc. are only used to represent the relative position relationship. When the absolute position of the object being described changes, the relative position relationship may change;
