[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention discloses a pulley dynamic balancing device, comprising a pulley 1 body, with rings 2 on both sides of the pulley 1 body. Multiple housings 3 are arranged in a ring structure on the outside of the rings 2. Each housing 3 has a mounting port at one end, and a mounting seat 15 is provided in each mounting port. Each mounting seat 15 has a ball groove at its center, with openings at both ends. A ball 16 is movably mounted inside each ball groove. A portion of the ball 16 extends outward through one opening and contacts the side of the synchronous pulley. A pressure sensor 4 is installed inside the housing 3. Another portion of the ball 16 extends outward through the other opening and contacts the detection end face of the pressure sensor 4. A first adjustment mechanism is installed on each ring 2 opposite the housing 3 to drive the housing 3 to extend and retract. A second adjustment mechanism is installed on one side of the pulley 1 body to drive the ring 2 to open or close.
[0023] In this embodiment, the first adjustment mechanism includes an adjustment column 12, a first lead screw 6, a first rotating block 7, and a first bearing. The outer ring surface of the ring body 2 is provided with an adjustment groove opposite to the housing 3. One end of the adjustment column 12 is inserted into the adjustment groove, and the other end is installed on the outer wall surface of the housing 3. The center of the adjustment column 12 is provided with a first lead screw hole that penetrates the adjustment column 12. The bottom surface of the adjustment groove is provided with a shaft hole that communicates with the outside. The first bearing is installed in the opening outside the shaft hole. The first lead screw 6 is installed in the inner ring of the first bearing. One end of the first lead screw 6 is threaded into the first lead screw hole, and the other end is fixedly connected to the first rotating block 7.
[0024] In this embodiment, the second adjustment mechanism includes a horizontal plate 9, a second lead screw 11, multiple sliders 10, a connecting plate 8, and multiple second bearings. The horizontal plate 9 is disposed on one side of the pulley 1 body. A groove is provided on the side of the horizontal plate 9 facing the pulley 1 body. The sliders 10 are all slidably disposed in the groove. The outer side of the sliders 10 is fixedly connected to the connecting plate 8. The other end of the connecting plate 8 is installed on the outer side of the ring 2. The sliders 10 are all provided with a second lead screw hole that penetrates the slider 10. Both ends of the groove are provided with through holes. The second bearings are all installed in the through holes. The second lead screw 11 is threadedly connected to the second lead screw hole. Both ends of the second lead screw 11 are installed in the inner ring of the second bearing. One end of the second lead screw 11 extends outward and is equipped with a second rotating block 14.
[0025] In this embodiment, the inner diameter of the openings at both ends of the ball groove is smaller than the diameter of the ball 16, so that the ball cannot fall out of the ball groove.
[0026] In this embodiment, buffer grooves are provided on both sides of the mounting port, and buffer blocks are installed in the buffer grooves. One end of each buffer block is installed on the mounting base. A compression spring is installed between the buffer block and the buffer groove. When the ball is squeezed, the ball can drive the mounting base. The movement of the mounting base drives the ball, causing the ball to move towards the pressure sensor. By squeezing the pressure sensor, the balance of the area can be known.
[0027] In this embodiment, a fixing block 5 is installed on the outside of the pressure sensor 4. The outer side of the fixing block 5 is in contact with the inner side of the housing 3. Screws are installed on the outside of the housing 3 to lock and fix the fixing block 5. After the screws are removed, the fixing block and the pressure sensor can be taken out along the housing, which facilitates their replacement.
[0028] In this embodiment, a fixing plate 13 is vertically installed on the horizontal plate 9. The fixing plate 13 has a straight groove, and bolts can pass through the straight groove to lock and fix the fixing plate on any platform to ensure the stability of the ring after installation.
[0029] In use, the position of the ring can be adjusted according to the width of the pulley. During adjustment, the second rotating block is rotated by a wrench. The rotation of the second rotating block drives the second lead screw, and the rotation of the second lead screw drives the slider, causing the slider to move inward along the slide groove in sync. The movement of the slider drives the connecting plate and the ring, and the movement of the ring drives the adjusting column and the housing. The housing then drives the ball in sync, so that one point of the ball contacts the side of the pulley.
[0030] After the above is completed, the first rotating block is rotated by a wrench. The rotation of the first rotating block drives the first lead screw, and the rotation of the first lead screw drives the adjusting column, causing the adjusting column to extend outward or retract along the adjusting groove. The movement of the adjusting block drives the housing until the ball on the housing contacts different positions on the side of the pulley.
[0031] After the pulley is driven, it will rotate rapidly. If the pulley is not balanced, it will wobble, which will squeeze the balls on both sides. The squeezing of the balls will cause the mounting base to move along the buffer groove. The movement of the balls will also squeeze the pressure sensor. The pressure sensor can quickly detect the balance at any position.
[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
