[0023] A highly practical indexing device includes a rotary cylinder 1, a one-way bearing 2, an indexing block 3, a positioning clip 4, a spring 5, and an indexing plate 6. The one-way bearing 2 is sleeved on the drive shaft of the rotary cylinder 1, and the indexing block 3 is sleeved on the one-way bearing 2. The drive shaft of the rotary cylinder 1 drives the one-way bearing 2 and the indexing block 3 to rotate. A positioning clip 4 is installed on the outer side of the indexing block 3, and a spring 5 is provided on the rear side of the positioning clip 4. A positioning groove 31 is provided on the outer side of the indexing block 3. The spring 5 pushes the positioning clip 4 into the positioning groove 31, causing the indexing block 3 to stop rotating. The indexing plate 6 is located on one side of the one-way bearing 2, the indexing block 3, the positioning clip 4, and the spring 5.
[0024] A highly practical indexing device is used for tightening screws or other components. A positioning clip 4 is mounted on the outer side of the indexing block 3, and a spring 5 is located on the rear side of the positioning clip 4. A positioning groove 31 is provided on the outer side of the indexing block 3. When the indexing block 3 is rotated by the rotary cylinder 1, the cylinder 1 rotates the indexing block 3 and then cuts off the air supply. The spring 5 holds the positioning clip 4 into the positioning groove 31, stopping the rotation of the indexing block 3. This allows for control of the rotation angle, which is beneficial for use. Tools and other components can be installed on the indexing plate 6, which is then rotated by the rotary cylinder 1. When the rotary cylinder 1 is inflated and rotates forward, it drives the one-way bearing 2 and the indexing block 3 to rotate. The spring 5 holds the positioning clip 4 into the positioning groove 31, stopping the rotation of the indexing block 3. This allows for control of the rotation angle. When the rotary cylinder 1 is inflated and rotates in reverse, since the one-way bearing 2 can only rotate in one direction, the drive shaft of the rotary cylinder 1 can freely return to its origin. The device has a simple structure, low manufacturing cost, and is easy to maintain and repair.
[0025] Specifically, four positioning grooves 31 are evenly arranged on the outer side of the indexing block 3, and positioning clips 4 are respectively provided on both sides of the indexing block 3. It can be rotated 90° or 180° for easy selection.
[0026] Specifically, the positioning groove 31 has a V-shaped cross-section, and one end of the positioning card 4 protrudes in an inverted V-shape. This facilitates the insertion or removal of the positioning card 4 from the positioning groove 31. Both sides of the positioning groove 31 are rounded, further facilitating the movement of the positioning card 4.
[0027] Specifically, the rotary cylinder 1 has a fixed block 7 at one end where the indexing block 3 is installed. The fixed block 7 has a relief groove at its center. The one-way bearing 2, the indexing block 3, the positioning clip 4, and the spring 5 are installed in the relief groove. The relief groove facilitates the installation of various components.
[0028] Specifically, a first mounting groove is provided on one side of the clearance groove, and a second mounting groove is provided on the side of the positioning card 4 that is opposite to the inverted V-shaped side. The two ends of the spring 5 are respectively inserted into the first mounting groove and the second mounting groove. This makes the spring 5 less likely to fall off during movement.
[0029] To further explain, a positioning post 8 is provided in the positioning groove. The positioning post 8 passes through the end of the positioning card 4 away from the inverted V-shape, and the positioning card 4 and the positioning post 8 are rotatably installed. This facilitates the swinging of the positioning card 4.
[0030] To further explain, a keyway is provided on the outer side of the one-way bearing 2, and a pin 32 protrudes from the inner side of the indexing block 3, which is inserted into the keyway. This allows the indexing block 3 and the one-way bearing 2 to rotate simultaneously, and the indexing block 3 is less likely to slip or fall off.
[0031] Specifically, the outer end of the indexing plate 6 is provided with several mounting holes 61. The mounting holes 61 are used to mount various cutting tools or components.
[0032] Other components and operations of the practical indexing device according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.
