DETAILED DESCRIPTION

[0019] 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.

[0020] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0021] Combination Figure 1-Figure 2 A quick-release split elastic chuck includes a connecting seat 1, a clamping body 2 arranged inside the connecting seat 1, a clamping block 22 arranged at one end of the clamping body 2, and multiple groups of clamping blocks 22 are arranged. A first conical surface 11 is opened at one end of the connecting seat 1 close to the clamping body 2, and a second conical surface 221 is arranged at one end of the clamping block 22 close to the first conical surface 11. A blocking component 3 for preventing impurities from entering is arranged between the first conical surface 11 and the second conical surface 221.

[0022] The utility model is further described below in conjunction with embodiments.

[0023] Embodiment 1:

[0024] See also Figure 1-Figure 3The blocking component 3 includes a fixed sleeve 31 movably connected to the outer surface of the connecting seat 1, a first ring sleeve 32 fixedly connected to one end of the fixed sleeve 31, a connecting sleeve 33 fixedly connected to the end of the first ring sleeve 32 away from the fixed sleeve 31, and a second ring sleeve 34 fixedly connected to the end of the connecting sleeve 33 away from the first ring sleeve 32. The second ring sleeve 34 is arranged on the outer surface of the clamping body 2, and the fixed sleeve 31 is arranged on the outer surface of the connecting seat 1. The second ring sleeve 34 is arranged on the outer surface of the clamping body 2, which is convenient for effectively preventing external impact from directly causing damage to the clamping body 2. In combination with the design of the blocking component 3, the first ring sleeve 32, the connecting sleeve 33 and the second ring sleeve 34 help to form a closed environment, prevent cutting fluid, dust or other impurities from entering the gap between the first conical surface 11 and the second conical surface 221, and reduce the wear of internal parts.

[0025] The fixing sleeve 31, the first ring sleeve 32, the connecting sleeve 33 and the second ring sleeve 34 are all made of rubber. The rubber has excellent airtightness and is convenient for forming a tight sealing ring to prevent coolant, cutting fluid, dust or other pollutants from entering the interior of the chuck. The rubber material is relatively soft and easy to deform, so it is easier to fit with other components during the assembly process.

[0026] The fixing sleeve 31 includes a first connecting ring 311 and a second connecting ring 312 movably arranged at one end of the first connecting ring 311. The other end of the first connecting ring 311 is fixedly connected to a limiting block 3111. A limiting groove 3121 is provided at one end of the second connecting ring 312 close to the limiting block 3111. The limiting block 3111 and the limiting groove 3121 are arranged correspondingly. A first locking bolt 4 is threadedly connected between the limiting block 3111 and the limiting groove 3121. The limiting block 3111 and the limiting groove 3121 are fixed by the threaded first locking bolt 4, so that the fixing sleeve 31 is fixed to the outer surface of the connecting seat 1.

[0027] A fixing seat 5 is movably provided at one end of the connecting seat 1 away from the clamping body 2, an external threaded channel 12 is provided on the outer surface of the connecting seat 1, and an internal threaded channel 52 is provided on the inner surface of the fixing seat 5, the external threaded channel 12 and the internal threaded channel 52 are provided correspondingly, and the connecting seat 1 and the fixing seat 5 are threadedly connected. At this time, the external threaded channel 12 and the internal threaded channel 52 are engaged with each other, ensuring that the fixing seat 5 and the connecting seat 1 have a strong connection force and stability to prevent relative movement between the components. At the same time, the threaded connection between the fixing seat 5 and the connecting seat 1 is convenient for disassembly and maintenance.

[0028] A first threaded hole 51 is provided on the outer surface of the fixing seat 5, and a second threaded hole 13 is provided on the outer surface of the connecting seat 1. The first threaded hole 51 and the second threaded hole 13 are arranged correspondingly, and a second locking bolt 6 is threadedly connected between the first threaded hole 51 and the second threaded hole 13. The fastening effect of the second locking bolt 6 enhances the connection strength between the fixing seat 5 and the connecting seat 1 during use.

[0029] A split opening 21 is provided on the outer surface of the clamping body 2, and gaps 222 are provided between the multiple groups of clamping blocks 22. The split opening 21 and the gaps 222 are interconnected. The split opening 21 enables the clamping body 2 to have a certain elastic deformation ability in the radial direction. When clamping the workpiece, the clamping block 22 can more tightly wrap and adapt to workpieces of different diameters or irregular shapes through the elastic expansion of the split opening 21, thereby improving the versatility and adaptability of the chuck.

[0030] When in use, the fixing sleeve 31 is set on the outer surface of the connecting seat 1, and the second ring sleeve 34 is set on the outer surface of the clamping body 2. The limit block 3111 and the limit groove 3121 are fixed by the first locking bolt 4 that is threadedly connected. At this time, the fixing sleeve 31 is fixed on the outer surface of the connecting seat 1. When the clamping body 2 is extended or retracted, the second ring sleeve 34 slides along the outer surface of the clamping body 2. The first ring sleeve 32, the connecting sleeve 33 and the second ring sleeve 34 help to form a closed environment to prevent cutting fluid, dust or other impurities from entering the gap between the first conical surface 11 and the second conical surface 221, thereby reducing the wear of internal parts. The tightening action of the second locking bolt 6 enhances the connection strength between the fixing seat 5 and the connecting seat 1 during use. Remove the second locking bolt 6, and the fixing seat 5 is threadedly connected to the connecting seat 1 for easy disassembly and maintenance.
