The end face of the product is pressed by washers and nuts for shaving. When changing to the next workpiece after each machining is completed, all nuts and washers must be removed before the workpiece can be changed. Using this tooling results in long workpiece change times and inconvenient operation. Utility Model Content

An inner movable sleeve 3 is fitted inside the support 2, and a first return spring 4 is installed at the bottom end of the inner movable sleeve 3. A first air chamber 5 is provided at the lower part of the inner movable sleeve 3. A first air inlet / outlet 6 is provided on the outer wall of the support 2, and the first air inlet / outlet 6 corresponds to the position of the first air chamber 5. A pressure ring 7 is bolted to the top of the support 2. An elastic clamping cone sleeve 8 is embedded at the top of the inner movable sleeve 3, and an inner support chuck 9 is fitted inside the elastic clamping cone sleeve 8. A second air chamber 10 is provided at the lower part of the inner movable sleeve 3, and an air hole 11 is provided on the second air chamber 10. The outer wall of the seat 2 is provided with a second air inlet / outlet 12, and the second air inlet / outlet 12 corresponds to the position of the air hole 11. The bottom of the inner support chuck 9 is fitted with a spindle 13, and the lower part of the spindle 13 is fitted with a second return spring 14. During the shaving process of the workpiece, it is not necessary to remove the elastic expansion sleeve. After the shaving is completed, it is only necessary to discharge the gas in the second air chamber 10. Under the action of the second return spring 14, the inner support chuck 9 can be lifted upward to release the elastic clamping cone sleeve 8, thereby releasing the workpiece. Then, air is introduced into the first air chamber 5, and a certain pressure is applied by pneumatic means to make the inner movable sleeve 3 move downward longitudinally, so that the elastic clamping cone sleeve 8 can be lowered, which is conducive to quick loading and unloading of gears and convenient operation.

[0021] Specifically, the support 2 is a cylindrical structure, and the bottom plate 1 is provided with a boss 15, which is engaged with the support 2 through the boss 15.

[0022] In this embodiment, the boss 15 is an assembly structure to facilitate the positioning and installation between the support 2 and the base plate 1.

[0023] Specifically, the pressure ring 7 presses against the top of the inner movable sleeve 3, and the elastic clamping cone sleeve 8 extends upward from the pressure ring 7.

[0024] In this embodiment, the pressure ring 7 is used to limit the inner movable sleeve 3 and also to support the workpiece.

[0025] Specifically, the bottom end of the inner movable sleeve 3 is provided with a positioning cylinder 16, and the first reset spring 4 is installed at the positioning cylinder 16.

[0026] In this embodiment, the positioning cylinder 16 is an assembly structure used for the installation and positioning of the first return spring 4.

[0027] Specifically, the cross-section of the mandrel 13 is T-shaped, and the lower part of the mandrel 13 extends outward from the inner movable sleeve 3.

[0028] In this embodiment, gas is introduced into the second air chamber 10, and a certain pressure is applied by pneumatic means to make the inner support chuck 9 move longitudinally, compressing the elastic clamping cone sleeve 8 to deform and expand outward, thereby achieving the purpose of inner clamping.

[0029] Specifically, the second return spring 14 is located inside the positioning cylinder 16 and is positioned between the lower part of the spindle 13 and the bottom of the inner movable sleeve 3.

[0030] In this embodiment, during disassembly, the gas in the second air chamber 10 is discharged, and under the action of the second return spring 14, the inner support chuck 9 can be pushed upward to loosen the elastic clamping cone sleeve 8, thereby releasing the workpiece.

[0031] Specifically, a first sealing ring 17 is installed on the upper and lower sides of the first air chamber 5, and the first sealing ring 17 is located between the inner movable sleeve 3 and the support 2.

[0032] In this embodiment, the first sealing ring 17 is a device for preventing liquid or gas leakage, which prevents liquid (such as hydraulic oil) or gas from leaking from the sealing surface by elastically deforming and filling the gap.

[0033] Specifically, a second sealing ring 18 is installed at the lower part of the inner support clamp 9, and the second sealing ring 18 is located between the inner support clamp 9 and the second air chamber 10.

[0034] In this embodiment, the second sealing ring 18 is a device for preventing liquid or gas leakage, which fills the gap by elastic deformation to prevent liquid (such as hydraulic oil) or gas from leaking from the sealing surface.

[0035] In use, this fixture requires an external air source connected through the first air inlet / outlet 6 and the second air inlet / outlet 12. The workpiece is fitted onto the elastic clamping cone sleeve 8, with the pressure ring 7 providing support. Gas is introduced into the second air chamber 10 through the second air inlet / outlet 12 and the air hole 11. A certain pressure is applied pneumatically, causing the inner support chuck 9 to move longitudinally downwards, compressing the elastic clamping cone sleeve 8 and causing it to expand outwards, thus achieving the purpose of internal clamping. During disassembly, simply vent the gas from the second air chamber 10. Under the action of the second return spring 14, the inner support chuck 9 can be lifted upwards to release the elastic clamping cone sleeve 8, thereby releasing the workpiece. Then, air is introduced into the first air chamber 5 through the first air inlet / outlet 6. A certain pressure is applied pneumatically, causing the inner movable sleeve 3 to move longitudinally downwards, thus lowering the elastic clamping cone sleeve 8. This facilitates quick loading and unloading of gears and is easy to operate. After removing the workpiece, simply vent the gas from the first air chamber 5. Under the action of the first return spring 4, the inner movable sleeve 3 can be lifted upwards to return to its original position.

[0036] In summary, this auxiliary tooling for gear processing eliminates the need to remove the elastic expansion sleeve during the shaving process. After shaving, only the gas in the second air chamber 10 needs to be discharged. Under the action of the second return spring 14, the inner support chuck 9 can be lifted upward to release the elastic clamping cone sleeve 8, thereby releasing the workpiece. Then, air is introduced into the first air chamber 5, and a certain pressure is applied pneumatically to cause the inner movable sleeve 3 to move longitudinally downward, thus lowering the elastic clamping cone sleeve 8. This facilitates quick loading and unloading of gears and is easy to operate.
