[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment proposes a chuck positioning and clamping device, including a chuck housing 1. Three flexible teeth 2 are evenly slidably connected to the chuck housing 1. Each of the three flexible teeth 2 has a groove 3 at its inner end. A locking block 4 is inserted into the groove 3. The locking block 4 is connected to the flexible teeth 2 via a first bolt assembly 5. A positioning head 6 is fixedly connected to the inner end of the locking block 4. A central disk 7 is detachably connected to the chuck housing 1 via bolts. A gear disk 8 is rotatably connected between the chuck housing 1 and the central disk 7. Three gyroscopes 9 are evenly rotatably connected to the chuck housing 1, each meshing with the gear disk 8. A pin 10 is provided on one side. The bottom end of the chuck housing 1 is detachably connected to a rear cover 11 by an internal hex bolt. A detachable positioning mechanism 12 is provided on the rear cover 11. The worn positioning head 6 can be easily replaced through the slot 3, the block 4, and the positioning head 6. The disassembly and assembly are efficient and do not require replacement of the entire soft tooth 2, which can also reduce the cost of use. By rotating the gyroscope 9, the gear disk 8 is rotated. The gear disk 8 drives the worm gear 13 to rotate synchronously, which in turn drives the claw tooth 14 and the soft tooth 2 to move, converting the rotational motion into linear motion, so that the soft tooth 2 and the positioning head 6 can clamp the workpiece.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the detachable positioning mechanism 12 further includes a mounting groove 1201 formed at the outer end of the rear cover 11. The mounting groove 1201 is bolted to a mounting plate 1202. A fixing post 1203 is fixedly connected to the center of the outer side wall of the mounting plate 1202. A plug block 1204 is fixedly connected to the outer end of the fixing post 1203. A socket 1205 is inserted into the plug block 1204. The socket 1205 is connected to the plug block 1204 via a second bolt assembly 1206. The outer end of 205 is fixedly connected to a positioning plate 1207. The positioning plate 1207 is aligned with the mounting part and then the plug 1204 is inserted into the socket 1205. The plug 1204 is then fixed to the socket 1205 by the second bolt assembly 1206. During maintenance and disassembly, the second bolt assembly 1206 is removed and the plug 1204 is taken out. During reassembly, the plug 1204 is inserted into the socket 1205. Compared with the prior art, there is no need to perform hole alignment, which improves the efficiency of disassembly and assembly.

[0031] like Figure 3 and Figure 4As shown, in a preferred embodiment, based on the above method, further, limiting protrusions 1208 are uniformly fixedly connected to the outer peripheral sidewall of the mounting plate 1202, and limiting grooves 1209 matching the limiting protrusions 1208 are provided on the mounting groove 1201, and a set of mounting holes are uniformly provided on the positioning plate 1207; the cooperation of the limiting protrusions 1208 and the limiting grooves 1209 can ensure the accurate installation of the mounting plate 1202 in the mounting groove 1201, prevent the mounting plate 1202 from rotating or shifting during the installation process, improve the installation accuracy and stability, and the mounting holes on the positioning plate 1207 facilitate the connection of the device to the equipment to realize the positioning of the chuck.

[0032] like Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, the upper end face of the gear disk 8 is fixedly connected to a worm gear 13, and the lower end face of the soft tooth 2 is fixedly connected to a claw tooth 14 that cooperates with the worm gear 13; the rotation of the gear disk 8 drives the worm gear 13 to rotate, thereby driving the claw tooth 14 and the soft tooth 2 to move, converting the rotational motion into linear motion, so that the soft tooth 2 clamps the workpiece.

[0033] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, grooves 15 are further provided on both the front and rear sidewalls of the soft tooth 2, and the cross-sectional shape of the slot 3 and the block 4 is T-shaped; the grooves 15 facilitate the assembly of the first bolt assembly 5 and provide it with operating space, and the T-shaped slots 3 and blocks 4 design can increase the connection strength between the block 4 and the soft tooth 2, ensuring the normal operation of the device.

[0034] like Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, the chuck housing 1 further includes a socket that matches the pin 10, and there are three pins 10; the socket facilitates the assembly of the pins 10, and the pins 10 are used to limit the gyroscope 9 to prevent it from coming out.

[0035] Specifically, when using this chuck positioning and clamping device: First, align and install the positioning plate 1207 with the mounting part using the fixing bolts. Then, fix the mounting plate 1202 into the mounting groove 1201 on the rear cover 11 using bolts. Next, insert the plug 1204 into the socket 1205. Then, fix the plug 1204 to the socket 1205 using the second bolt assembly 1206. For maintenance and disassembly, simply remove the second bolt assembly 1206 and take out the plug 1204. For reassembly, simply insert the plug 1204 into the socket 1205. No further steps are required. Align the mounting holes of the chuck with the mounting holes of the mounting part; when in use, rotate the gyroscope 9 to rotate the gear plate 8, which drives the worm gear 13 to rotate synchronously, thereby driving the claw teeth 14 and the soft teeth 2 to move, converting the rotational motion into linear motion, so that the soft teeth 2 and the positioning head 6 can clamp and release the workpiece. When it is necessary to replace the worn positioning head 6, remove the first bolt assembly 5, then pull out the positioning head 6 and the locking block 4, and then insert the new positioning head 6 and the locking block 4 into the slot 3. Finally, connect and fix the locking block 4 to the soft teeth 2 through the first bolt assembly 5 to complete the replacement.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
