[0002] Tapered sleeve polishing machines are mainly used to polish the surface of workpieces such as tapered sleeves. Through polishing, burrs, oxide layers, scratches and other uneven parts on the surface of the workpiece can be removed, making the surface smoother and shinier. The positioning mechanism is a key component to ensure that the tapered sleeve maintains an accurate position during the polishing process.
[0003] Existing positioning mechanisms typically use fixed plates of a single size to fix tapered sleeve workpieces. While this method is simple and reliable, it lacks flexibility and cannot adapt to tapered sleeve workpieces of different shapes and sizes. It requires frequent replacement of the fixed plate, which significantly affects work efficiency and polishing accuracy. With the diversification of workpiece types, the existing positioning method may not be able to meet production needs. Therefore, it is necessary to improve the auxiliary positioning structure of the tapered sleeve polishing machine to solve the above problems. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please see Figure 1 - Figure 5 This utility model provides an embodiment of an auxiliary positioning structure for a conical sleeve polishing machine, including a flat plate 2, a hollow cylinder 1, and a polishing mechanism. The hollow cylinder 1 is rotatably connected inside the flat plate 2. Large vertical plates 5 are fixedly connected to the left and right sides of the flat plate 2. A polishing mechanism for polishing the conical sleeve is provided on the side of the large vertical plate 5 near the hollow cylinder 1. A base plate 4 is fixedly connected to the bottom of the large vertical plate 5, and a large motor 3 is fixedly connected to the top of the base plate 4. The hollow cylinder 1 is fixedly connected to the output end of the large motor 3. A hollow cylinder 61 is fixedly connected inside the hollow cylinder 1. A fixing rod 612 is slidably connected inside the hollow cylinder 61, and an arc-shaped plate is fixedly connected to the outside of the fixing rod 612. 66. A trapezoidal plate 611 is fixedly connected to the inner side of the fixing rod 612. A spring 67 is fixedly connected between the trapezoidal plate 611 and the hollow cylinder 61. The fixing rod 612 drives the arc plate 66 to extend, thereby fixing the conical sleeve from the inside. The conical sleeve is placed on the outside of the hollow cylinder 61. The trapezoidal plate 611 moves, and the trapezoidal plate 611 drives the fixing rod 612 and compresses the spring 67. The fixing rod 612 drives the arc plate 66, and the arc plate 66 extends and tightens inside the bushing, fixing the bushing. Then, the large motor 3 is started. The large motor 3 drives the hollow cylinder 1, the hollow cylinder 1 drives the hollow cylinder 61, and the hollow cylinder 61 drives the conical sleeve to rotate. Then, the polishing mechanism is started to polish the conical sleeve.
[0021] Please see Figure 2 - Figure 3In this embodiment, a circular cover 65 is fixedly connected to the top of the hollow cylinder 61. A threaded post 62 is threadedly connected to the inside of the hollow cylinder 61. A connecting post 610 is fixedly connected to the top of the threaded post 62. A rotating rod 64 is fixedly connected to the top of the connecting post 610. The rotating rod 64 is rotatably connected inside the circular cover 65. A square pyramid 63 is rotatably connected to the outside of the connecting post 610. A hollow column a68 is fixedly connected to the bottom of the circular cover 65. A round rod 69 is slidably connected inside the hollow column a68. The round rod 69 is fixedly connected inside the square pyramid 63. The position of the trapezoidal plate 611 is changed by the up-and-down movement of the square pyramid 63, thereby pushing the arc plate 66 to extend, thus achieving the purpose of fixing different conical sleeve workpieces. The square pyramid 63 and the trapezoidal plate 611 are respectively provided with inclined surfaces at opposite positions. There are two trapezoidal plates 611, and the two trapezoidal plates 611 are symmetrically arranged on the square pyramid 611. On both sides of 3, the trapezoidal plate 611 contacts the inclined surface of the square pyramid 63. By symmetrically arranging the trapezoidal plate 611, the contact area between the arc plate 66 and the cone sleeve is increased, thereby improving the positioning accuracy of the positioning mechanism. Two hollow columns a68 and two round rods 69 are respectively arranged, and the hollow columns a68 and the round rods 69 are symmetrically arranged between the round cover 65 and the square pyramid 63. The hollow columns a68 and the round rods 69 limit the square pyramid 63 without affecting its up and down movement. The symmetrical arrangement further improves the stability of the positioning structure. There is a certain distance between the hollow cylinder 61 and the square pyramid 63, and the size of the trapezoidal plate 611 is smaller than the distance between the square pyramid 63 and the inner wall of the hollow cylinder 61. By limiting the size of the trapezoidal plate 611, the range of motion of the trapezoidal plate 611 inside the hollow cylinder 61 is maximized, thereby fixing more cone sleeve workpieces of different sizes.
[0022] Please see Figure 1 , Figure 4 - Figure 5In this embodiment, the polishing mechanism includes an electric telescopic rod 71, which is fixedly connected to the side of the large vertical plate 5 near the hollow cylinder 1. A small vertical plate 72 is fixedly connected to the inner side of the electric telescopic rod 71. A flat plate 73 is fixedly connected to the top of the small vertical plate 72. A small motor 74 is fixedly connected to the top of the flat plate 73. A short rod 75 is fixedly connected to the output end of the small motor 74. A bevel gear a 76 is fixedly fixed to the inner side of the short rod 75. A bevel gear b 77 meshes with the outer side of the bevel gear a 76. A long rod 78 is fixedly connected to the bottom of the bevel gear b 77. The long rod 78 is rotatably connected inside the flat plate 73. A polishing wheel 7 is provided on the outer side of the long rod 78. 9. The external thread of the long rod 78 is connected to a nut 710, and the internal thread of the small vertical plate 72 is connected to a screw 712. A support plate 711 is set on the outside of the screw 712, and a rotating shaft 713 is rotatably connected inside the support plate 711. The polishing wheel 79 can be easily and quickly replaced through the screw 712 and the support plate 711. Not only is the operation simple and quick, but the symmetrical arrangement on both sides of the hollow cylinder 1 can also assist in the positioning of the cone sleeve while polishing. The rotating shaft 713 has a limiting hole at the corresponding position of the long rod 78, and the long rod 78 is set inside the limiting hole. The limiting hole can limit and fix the long rod 78, and at the same time, it also plays a supporting role when rotating.
[0023] During operation, the tapered sleeve is fitted onto the outside of the hollow cylinder 61. Rotating the rotating rod 64 drives the connecting rod 610, which in turn drives the threaded rod 62. The threaded rod 62 slides upwards inside the hollow cylinder 61 via the threads. The threaded rod 62 pushes the square cone 63, which in turn pushes the trapezoidal plate 611 closer to the inner wall of the hollow cylinder 61. The trapezoidal plate 611 drives the fixing rod 612, which in turn causes the arc-shaped plate 66 to extend, causing it to tighten inside the tapered sleeve. The movement of the trapezoidal plate 611 compresses the spring 67, which allows the trapezoidal plate 611 to return to its original position and conform to the inner wall of the hollow cylinder 61. The inclined surface of the square pyramid 63 is then activated, followed by the start of the large motor 3. The output of the large motor 3 rotates, driving the hollow cylinder 1 to rotate. The hollow cylinder 1 drives the hollow cylinder 61, which in turn drives the tapered sleeve workpiece to rotate at a constant speed, thereby changing the angle of the tapered sleeve workpiece and making the contact surface between the tapered sleeve workpiece and the polishing wheel 79 more comprehensive. At the same time, the small motor 74 is activated, and the output of the small motor 74 drives the short rod 75 to rotate. The short rod 75 drives the bevel gear a76, which in turn drives the bevel gear b77. The bevel gear b77 drives the long rod 78, which in turn drives the polishing wheel 79. Finally, the electric telescopic rod 71 is activated to polish the tapered sleeve workpiece.
[0024] Through the above steps, the rotating rod 64 drives the square cone 63 to push the arc plate 66, causing the arc plate 66 to be stretched and tightened inside the tapered sleeve workpieces of different sizes, thereby fixing and positioning the tapered sleeve workpieces of different sizes, thus solving the problem that the positioning mechanism lacks flexibility and cannot adapt to tapered sleeve workpieces of different sizes.
