DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] like Figure 1-Figure 3 As shown, a positioning core of a gear sleeve includes a mounting plate 1, a positioning shaft 4 is connected to the middle position of the upper part of the mounting plate 1, and an introduction shaft 5 is connected to the upper end of the positioning shaft 4. The diameter of the upper end of the introduction shaft 5 is smaller than the diameter of the lower end. When positioning the gear sleeve, the introduction shaft 5 is first inserted into the center hole of the gear sleeve. The introduction shaft 5 is tapered as a whole, making insertion more convenient. The chamfered corner of the upper end of the introduction shaft 5 also facilitates the insertion of the introduction shaft 5 into the center hole of the gear sleeve.
[0019] The outer periphery of the positioning shaft 4 is provided with a mounting groove 6, and a mounting frame 9 is installed in the mounting groove 6. A clamping block 7 is arranged in the mounting frame 9, and a spring 10 is connected between the clamping block 7 and the mounting frame 9. The clamping block 7 includes a moving block 11 located in the mounting frame 9, and the outer periphery of the moving block 11 is flush with the outer periphery of the positioning shaft 4. A protrusion 13 is connected to the outer periphery of the moving block 11, and an inclined surface 14 is arranged at the upper position of the outer side of the protrusion 13, and the inclined surface 14 is inclined outward and downward. When the positioning shaft 4 is inserted into the center hole of the gear sleeve, due to the setting of the inclined surface 14, the clamping block 7 is compressed into the mounting frame 9 when it contacts the gear sleeve. After the positioning shaft 4 is fully inserted, the protrusion 13 on the clamping block 7 pops out again and is stuck on the upper end of the gear sleeve, and the mounting plate 1 is against the lower end of the gear sleeve, clamping and fixing the gear sleeve from the upper and lower ends. The positioning shaft 4 plays the role of center positioning.
[0020] A guide groove 12 is provided inside the moving block 11 , and one end of the spring 10 connected to the moving block 11 is located in the guide groove 12 . The guide groove 12 limits the spring 10 and guides the movement of the moving block 11 .
[0021] In order to better guide the movement of the moving block 11 , 17 is connected to the inner side walls before and after the installation groove 6 . The setting direction of 17 is perpendicular to the axial direction of the positioning shaft 4 . The moving block 11 is provided with a limiting groove matched with 17 .
[0022] Furthermore, a filling block 15 is provided in the installation groove 6. By adjusting the number of the filling blocks 15 provided above and below the installation frame 9, the position of the installation frame 9 in the installation groove 6 can be adjusted, thereby adjusting the height of the protrusion 13, and can be used for tooth sleeves with the same center hole size but different lengths.
[0023] Furthermore, a connection groove 8 is provided in the filling block 15, and the outer end of the connection groove 8 is connected to the outer side of the filling block 15. The filling block 15 is inserted into the mounting groove 6 by an interference fit to ensure the firmness of the fixing to the mounting frame 9. By providing the connection groove 8, the front end of an external tool can be inserted into the connection groove 8 and stuck, so that the filling block 15 can be easily pulled out from the mounting groove 6.
[0024] Furthermore, a plurality of mounting holes 2 are formed on the mounting plate 1 , and the plurality of mounting holes 2 are evenly distributed, and the mounting plate 1 is mounted on other mechanisms through the mounting holes 2 .
[0025] Furthermore, a positioning block 3 is connected to the middle position of the lower part of the mounting plate 1, and the positioning block 3 is installed on other mechanisms for positioning the mounting hole 2.
[0026] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
