Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0043] Please refer to Figures 1 to 5 , and a fixture quick-release structure provided by an embodiment of the present application will be described below. The fixture quick-release structure includes a first connecting seat 1, a second connecting seat 2, a locking assembly 3, and an unlocking assembly 4. A clamping groove 10 is provided on the first connecting seat 1. A clamping head 20 is provided on the second connecting seat 2, and the clamping head 20 is used for plugging and mating with the clamping groove 10 along a first direction. The locking assembly 3 is used to lock the clamping head 20 in the clamping groove 10. The unlocking assembly 4 is used to release the locking state of the locking assembly 3 on the clamping head 20.

[0044] During assembly, first, the unlocking assembly 4 is used to make the locking assembly 3 in a non-locked state, so that the clamping head 20 of the second connecting seat 2 can be smoothly inserted into the clamping groove 10. After the plugging is completed, the locking assembly 3 locks the clamping head 20 of the second connecting seat 2 in the clamping groove 10, thereby realizing the assembly and fixation of the second connecting seat 2 and the first connecting seat 1.

[0045] During disassembly, the unlocking assembly 4 is used to release the locking state of the locking assembly 3, so that the clamping head 20 of the second connecting seat 2 can be smoothly withdrawn from the clamping groove 10, and the disassembly of the second connecting seat 2 and the first connecting seat 1 can be realized.

[0046] The fixture quick-release structure provided by the present application, compared with the prior art, uses the clamping groove 10 of the first connecting seat 1 to cooperate with the clamping head 20 of the second connecting seat 2 to achieve connection. At the same time, under the action of the locking assembly 3, the clamping head 20 is locked in the clamping groove 10 to realize the rapid assembly of the fixture quick-release structure. Under the action of the unlocking assembly 4, the clamping head 20 can be taken out from the clamping groove 10 to realize the rapid disassembly of the fixture quick-release structure. Applying the fixture quick-release structure provided by the embodiment of the present application to a processing device, by installing the first connecting seat on a machine tool and installing a fixture on the second connecting seat, it is possible to avoid frequently disassembling and assembling the parts to be processed from the fixture, but to realize rapid disassembly and assembly through the cooperation of the second connecting seat and the first connecting seat, so as to quickly switch the processing of different parts, improve the replacement efficiency of the parts, and thus improve the processing efficiency.

[0047] In another embodiment of the present application, please refer to Figure 3 and Figure 4 , a clamping groove 200 is provided on the circumferential side of the clamping head 20. The locking assembly 3 includes a clamping member and an elastic pushing unit 31. The clamping member is arranged along the groove wall of the clamping groove 10, and the clamping member can be partially inserted into the clamping groove 200. The elastic pushing unit 31 is used to push the clamping member so that the clamping member is clamped tightly in the clamping groove 200.

[0048] When the clamping head 20 is inserted into the clamping groove 10, the engaging part is partially engaged into the engaging groove 200 of the clamping head 20, so that the clamping head 20 can be clamped in the clamping groove 10. At the same time, under the action of the elastic pushing unit 31, the engaging part is tightly clamped in the engaging groove 200, so that the clamping head 20 is locked in the clamping groove 10, realizing the assembly and fixation of the first connecting seat 1 and the second connecting seat 2.

[0049] In another embodiment of the present application, please continue to refer to Figure 3 and Figure 4 The end of the clamping head 20 close to the first connecting seat 1 has a chamfer structure 201.

[0050] By providing the chamfer structure 201 at the end of the clamping head 20 close to the first connecting seat 1, the clamping head 20 can be inserted into the clamping groove 10 more smoothly.

[0051] In another embodiment of the present application, please refer to Figure 2 and Figure 4 The engaging part is a ball 30. The groove wall of the clamping groove 10 is radially extended with an installation groove 11 for accommodating the ball 30. The width of the notch of the installation groove 11 is smaller than the diameter length of the ball 30.

[0052] Using the ball 30 as the engaging part, the ball 30 can roll in the installation groove 11. At the same time, by making the notch of the installation groove 11 smaller than the diameter of the ball 30, the ball 30 is restricted to roll in the installation groove 11 and will not break out of the installation groove 11. This structure can make the engaging process with the clamping head 20 smoother and the reliability of the engaging structure better.

[0053] In another embodiment of the present application, the shape of the installation groove 11 is an annular groove, that is, the installation groove 11 is circumferentially surrounded by the groove wall of the clamping groove 10. The number of balls 30 is multiple, and multiple balls 30 are all accommodated in the installation groove 11. Using multiple balls 30 can improve the engaging effect with the clamping head 20. Correspondingly, the shape of the engaging groove 200 on the clamping head 20 is an annular groove to be able to be engaged by multiple balls 30, and the clamping head 20 can be inserted into the clamping groove 10 in any direction and engaged with the engaging part.

[0054] In another embodiment of the present application, please refer to Figure 4 and Figure 5, a push groove 12 communicating with the installation groove 11 is provided on the first connecting seat 1. The elastic pushing unit 31 includes a push block 310 and an elastic member 311. The push block 310 is arranged in the push groove 12. The push block 310 can slide between the push groove 12 and the installation groove 11 along the first direction. When the push block 310 extends into the installation groove 11, the push block 310 pushes the engaging member towards the notch of the installation groove 11. Two ends of the elastic member 311 are respectively connected to the push block 310 and the first connecting seat 1. The elastic member 311 is used to make the push block 310 slide towards the installation groove 11.

[0055] Under the action of the elastic member 311, the push block 310 is pushed into the installation groove 11 and remains in contact with the installation groove 11. Here, the push block 310 can be partially extended into the installation groove 11 or fully extended into the installation groove 11. At the same time, the push block 310 abuts against the ball 30 accommodated in the installation groove 11 and pushes the ball 30 to roll towards the notch of the installation groove 11, so that the ball 30 is fully extended into the engaging groove 200, so that the ball 30 can be tightly held in the engaging groove 200 of the clamping head 20, ensuring that the second connecting seat 2 is locked on the first connecting seat 1.

[0056] Specifically, when the push block 310 extends into the installation groove 11, the push block 310 extends along the inner wall of the installation groove 11, so that the ball 30 is pushed towards the notch of the installation groove 11.

[0057] In addition, when the number of balls 30 is multiple, the push block 310 is of an annular structure. Therefore, when the push block 310 extends into the installation groove 11, the push block 310 can push multiple balls 30 synchronously.

[0058] In another embodiment of the present application, please continue to refer to Figure 4 and Figure 5 , the elastic member 311 is a spring, and the number of springs is multiple. The multiple springs are distributed at intervals along the circumference of the push block 310 to ensure that the push plate can slide stably along the first direction.

[0059] In another embodiment of the present application, please refer to Figure 5 , the unlocking assembly 4 includes a driving member, and the driving member is used to make the push block 310 slide along the first direction towards the push groove 12.

[0060] The driving member is used to drive the push block 310 to slide along the first direction towards the push groove 12, so that the push block 310 exits the installation groove 11. In this way, the ball 30 can retract into the installation groove 11, so that the clamping head 20 can be withdrawn from the clamping groove 10.

[0061] In another embodiment of the present application, please continue to refer to Figure 5 , the push groove 12 is a closed groove, and the driving member is a pneumatic device 40.

[0062] Specifically, an interface 13 is provided on the first connecting seat 1. The interface 13 communicates with the pushing groove 12, and the pneumatic device 40 is connected to the interface 13. During use, the pneumatic device 40 is ventilated to enable the pushing block 310 to slide in the direction of the pushing groove 12. After use, the pneumatic device 40 sucks air or the pneumatic device 40 is directly removed, and external gas is introduced into the pushing groove 12 through the interface 13. At the same time, under the action of the elastic member 311, the pushing plate is restored to extend into the installation groove 11.

[0063] In another embodiment of the present application, refer to Figure 6 , the pushing block 310 includes a bottom plate 3100 and a side pushing plate 3101. The side pushing plate 3101 is connected to the bottom plate 3100. The bottom plate 3100 is accommodated in the pushing groove 12, and the side pushing plate 3101 can extend into the installation groove 11. Among them, the bottom plate 3100 always seals the communication port between the pushing groove 12 and the installation groove 11, so that the pushing groove 12 is a closed groove. This structure is similar to the well-known syringe structure. The pushing block 310 is equivalent to the piston rod in the syringe, and the bottom plate 3100 in the pushing block 310 is equivalent to the plug on the piston rod, and the pushing groove 12 is equivalent to the inner cavity of the syringe barrel.

[0064] In another embodiment of the present application, please continue to refer to Figure 6 , an abutting wall 3102 is provided at the end of the pushing block 310 close to the installation groove 11. The radial thickness of the abutting wall 3102 gradually decreases from the side close to the pushing groove 12 to the side away from the pushing groove 12.

[0065] When the pushing block 310 extends into the installation groove 11, the thickness of the abutting wall 3102 gradually increases. The ball 30 first contacts the abutting wall 3102 on the pushing block 310, and the abutting wall 3102 can follow the outer circumference of the ball 30 and gradually push the ball 30 towards the notch of the installation groove 11.

[0066] When the pushing block 310 withdraws from the installation groove 11, the thickness of the abutting wall 3102 gradually decreases, and the ball 30 can shrink into the installation groove 11 against the abutting wall 3102.

[0067] In another embodiment of the present application, a guiding structure is provided on the groove wall of the installation groove 11 for guiding the ball 30 to roll away from the notch of the installation groove 11.

[0068] Specifically, the width of the installation groove 11 in the first direction gradually decreases from the side away from the notch of the installation groove 11 to the side close to the notch of the installation groove 11 to form a guiding structure. Thus, when the pushing force of the pushing block 310 on the ball 30 is removed, the ball 30 can roll along the groove wall of the installation groove 11 and shrink into the installation groove 11.

[0069] In another embodiment of the present application, please look back at Figure 2 and Figure 3, the fixture quick-release structure further includes a positioning component, and the positioning component is used to limit the relative rotation between the first connecting seat 1 and the second connecting seat 2 around the first direction.

[0070] Specifically, the positioning component includes a positioning block 50 and a positioning groove 51. The positioning block 50 is provided on the side of the second connecting seat 2 close to the first connecting seat 1, and the positioning groove 51 is provided on the side of the first connecting seat 1 close to the second connecting seat 2. The positioning block 50 can be inserted into the positioning groove 51.

[0071] Alternatively, in some other embodiments, the positioning block 50 is provided on the side of the first connecting seat 1 close to the second connecting seat 2, and the positioning groove 51 is provided on the side of the second connecting seat 2 close to the first connecting seat 1. The positioning block 50 can be inserted into the positioning groove 51.

[0072] Please refer to Figure 1 , this application also provides a processing device, and the processing device includes a machine tool. The fixture quick-release structure provided in the embodiments of this application is provided on the machine tool. Specifically, the fixture quick-release structure is fixedly installed on the machine tool through the second connecting seat 2.

[0073] The processing device provided in this application adopts the fixture quick-release structure provided in the embodiments of this application. By quickly disassembling and assembling between the second connecting seat 2 and the first connecting seat 1, the replacement of the parts to be processed is realized, and there is no need to frequently disassemble and assemble the parts to be processed from the fixture, which improves the replacement efficiency of the parts and thus improves the processing efficiency.

[0074] The above are only the preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of this application shall be included in the protection scope of this application.
