The clamping component includes a screw rod and two clamping blocks arranged oppositely along a second direction. The screw rod is rotatably arranged on the side of the connecting seat away from the positioning seat. Both clamping blocks are slidably arranged on the side of the connecting seat away from the positioning seat. A clamping groove for placing the workpiece is formed between the two clamping blocks. The screw rod is provided with two threaded sections with opposite thread directions in the second direction, and the two clamping blocks are respectively threadedly connected with the two threaded sections.

[0007] In one of the embodiments of the first aspect, the number of the clamping beads is multiple, and the multiple clamping beads are circumferentially distributed along the groove wall of the accommodating groove.

[0008] In one of the embodiments of the first aspect, the multiple clamping beads are all movably placed in the accommodating groove, and the width of the groove opening of the accommodating groove is smaller than the diameter of the clamping bead.

[0009] In one embodiment of the first aspect, an arc surface structure is provided at the notch of the accommodating groove, and the arc surface structure causes the clamping beads to roll into the accommodating groove; the workpiece processing and clamping mechanism further includes a moving member, a first driving member, and a second driving member. The moving member can move between a first position and a second position relative to the positioning seat. When the moving member moves from the first position to the second position, the clamping beads are pushed out by the moving member and extend into the positioning slot; when the moving member moves from the second position to the first position, the clamping beads roll into the accommodating groove. The first driving member is used to drive the moving member to move from the first position to the second position, and the second driving member is used to drive the moving member to move from the second position to the first position.

[0010] In one embodiment of the first aspect, the first driving member includes an elastic member. A moving groove communicating with the accommodating groove is formed on the positioning seat. The moving member is slidably arranged between the moving groove and the accommodating groove. The elastic member abuts between the moving member and the positioning seat, and the elastic force of the elastic member can push the moving member to move from the first position to the second position.

[0011] In one embodiment of the first aspect, the second driving member includes a pneumatic device. The moving member includes a pushing portion and a blocking portion connected to each other. The pushing portion can extend into the accommodating groove and abut against the clamping beads. The blocking portion is accommodated in the moving groove and blocks the communication port between the moving groove and the accommodating groove, so that the moving groove forms a closed groove. The pneumatic device is connected to the positioning seat, and the pneumatic device communicates with the moving groove.

[0012] In one embodiment of the first aspect, an air passage is formed in the positioning seat, and the air passage communicates the moving groove and the pneumatic device.

[0013] In one embodiment of the first aspect, two spaced-apart protrusions are provided on the side of the connecting seat away from the positioning seat. A mating seat is fixedly connected to each of the two protrusions. A strip-shaped notch is provided on the side of the mating seat close to the protrusion to cooperate with the protrusion to form a sliding groove. A sliding block is provided on the clamping block, and the sliding block is slidably connected to the corresponding sliding groove.

[0014] In one embodiment of the first aspect, two convex rings are provided on the circumference of the screw rod. The two convex rings are spaced apart along the second direction.

[0017] For the workpiece processing and clamping mechanism of the present application, the positioning seat is fixedly installed on the machine tool. The positioning slot and the positioning post between the positioning seat and the connecting seat are inserted and matched, which can quickly limit the position of the connecting seat on the machine tool. Then, under the clamping action of the clamping beads and the positioning post, the positioning seat and the connecting seat are assembled and fixed. At the same time, the two clamping blocks of the clamping assembly are slidably arranged on the connecting seat. By rotating the screw rod, the two clamping blocks can move away from each other or move closer to each other, thereby playing a centering role on the workpiece in the clamping groove and ensuring the processing position of the workpiece on the machine tool. Therefore, by adopting the workpiece processing and clamping mechanism provided by the present application, whether only disassembling and assembling parts or disassembling and assembling the overall clamping assembly, the assembly position can be accurately ensured, and it has high repeat positioning characteristics.

[0018] For the processing system of the present application, the workpiece processing and clamping mechanism provided by the embodiments of the present application is adopted. By fixedly installing the positioning seat in the workpiece processing and clamping mechanism on the machine tool, the positioning slot of the positioning seat and the positioning post of the connecting seat can play a positioning role in the disassembly and assembly of the clamping assembly. The clamping assembly drives the two clamping blocks to move away from each other or move closer to each other by rotating the same screw rod, thereby playing a centering role on the workpiece in the clamping groove and ensuring the processing position of the workpiece on the machine tool. Therefore, whether only disassembling and assembling parts or disassembling and assembling the overall clamping assembly, the assembly position can be accurately ensured, and it has high repeat positioning characteristics.

[0035] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0036] Please refer to Figure 1 and Figure 2 together. Now, an explanation will be given for the workpiece processing and clamping mechanism provided by the embodiments of this application. The workpiece processing and clamping mechanism includes a positioning seat 1, a connecting seat 2, and a clamping assembly 3. A positioning slot 10 is provided on the positioning seat 1, and a positioning pin 20 is provided on the connecting seat 2. The positioning pin 20 can be inserted into the positioning slot 10 along a first direction. An accommodation groove 11 is radially extended and provided on the groove wall of the positioning slot 10. A clamping ball 12 is provided in the accommodation groove 11. The clamping ball 12 can extend into the positioning slot 10 and be clamped with the positioning pin 20. The clamping assembly 3 includes a screw 30 and two clamping blocks 31 oppositely arranged along a second direction. The screw 30 is rotatably arranged on the side of the connecting seat 2 away from the positioning seat 1. The two clamping blocks 31 are both slidably arranged on the side of the connecting seat 2 away from the positioning seat 1. A clamping groove 32 for placing the workpiece is formed between the two clamping blocks 31. The screw 30 is successively provided with two thread segments 300 with opposite thread directions in the second direction. The two clamping blocks 31 are respectively threadedly connected with the two thread segments 300.

[0037] Among them, the positioning seat 1, the connecting seat 2, and the clamping assembly 3 are connected in sequence. That is, one side of the connecting seat 2 is fixedly assembled with the positioning seat 1, and the clamping assembly 3 is installed on the other side of the connecting seat 2.

[0038] For the workpiece processing and clamping mechanism provided by this application, the positioning seat 1 is fixedly installed on the machine tool 1000. The positioning seat 1 and the connecting seat 2 are inserted and matched through the positioning slot 10 and the positioning pin 20, which can quickly define the position of the connecting seat 2 on the machine tool 1000. Then, under the clamping action of the clamping ball 12 and the positioning pin 20, the positioning seat 1 and the connecting seat 2 are fixedly assembled. At the same time, the two clamping blocks 31 of the clamping assembly 3 are slidably arranged on the connecting seat 2. By rotating the screw 30, the two clamping blocks 31 can move away from each other or move closer to each other, thereby being able to center the workpiece in the clamping groove 32 and ensuring the machining position of the workpiece on the machine tool 1000. Therefore, by adopting the workpiece processing and clamping mechanism provided by this application, whether only disassembling and assembling parts or disassembling and assembling the overall clamping assembly 3, the assembly position can be accurately ensured, and it has high repeat positioning characteristics.

[0039] In another embodiment of this application, please refer to Figures 3 to 4, the number of the clamping beads 12 is multiple, and the multiple clamping beads 12 are circumferentially distributed around the groove wall of the accommodating groove 11. By adopting multiple clamping beads 12 to abut against the circumferential side of the positioning stud 20, the clamping stability is improved.

[0040] In another embodiment of the present application, please continue to refer to Figures 3 to 4 , the multiple clamping beads 12 are all movably placed in the accommodating groove 11, and the width of the notch of the accommodating groove 11 is smaller than the diameter of the clamping bead 12.

[0041] Adopting the movable clamping bead 12 to engage with the positioning stud 20 can make the engaging process smoother and the engaging reliability better. By setting the notch of the accommodating groove 11 to be smaller than the diameter of the clamping bead 12, the clamping bead 12 is restricted to roll within the accommodating groove 11 and will not break out of the accommodating groove 11.

[0042] In another embodiment of the present application, refer to Figure 2 and Figure 3 , a clamping groove 200 is provided on the circumferential side of the positioning stud 20. When the positioning stud 20 is inserted into the positioning slot 10, the part of the clamping bead 12 extending into the positioning slot 10 is clamped into the clamping groove 200, so that the positioning stud 20 is clamped in the positioning slot 10.

[0043] In another embodiment of the present application, please refer to Figures 3 to 4 , the notch of the accommodating groove 11 is provided with an arc surface structure, and the arc surface structure here is formed by gradually narrowing the groove width of the accommodating groove 11 from inside to outside. Therefore, the clamping bead 12 can be accommodated in the accommodating groove 11 without falling out of the accommodating groove 11. The arc surface structure makes the clamping bead 12 roll into the accommodating groove 11. The workpiece processing and clamping mechanism further includes a moving member 4, a first driving member and a second driving member. The moving member 4 can move between a first position and a second position relative to the positioning seat 1. When the moving member 4 moves from the first position to the second position, the clamping bead 12 is pushed out by the moving member 4 and extends into the positioning slot 10; when the moving member 4 moves from the second position to the first position, the clamping bead 12 rolls into the accommodating groove 11. The first driving member is used to drive the moving member 4 to move from the first position to the second position, and the second driving member is used to drive the moving member 4 to move from the second position to the first position.

[0044] In the natural state, the clamping bead 12 naturally rolls into the accommodating groove 11 along the arc surface structure and loses the function of clamping the positioning stud 20. Under the action of the first driving member, the moving member 4 moves from the first position to the second position, so that the clamping bead 12 is pushed out by the moving member 4 and extends into the positioning slot 10, and thus can play a role in clamping the positioning stud 20. Under the action of the second driving member, the moving member 4 moves from the second position to the first position, and the moving member 4 loses the function of pushing the clamping bead 12 into the positioning slot 10. The clamping bead 12 can naturally roll into the accommodating groove 11, so that the positioning stud 20 can be withdrawn from the positioning slot 10.

[0045] In another embodiment of the present application, please refer to Figure 3 and Figure 4 , the first driving member is an elastic member 5. A moving groove 13 communicating with the accommodating groove 11 is formed on the positioning seat 1. The moving member 4 is slidably disposed between the moving groove 13 and the accommodating groove 11. The elastic member 5 abuts between the moving member 4 and the positioning seat 1. The elastic force of the elastic member 5 can push the moving member 4 from the first position to the second position.

[0046] Under the elastic force of the elastic member 5, the moving member 4 is pushed to the second position and is maintained in the second position state. By using the elastic member 5 as the driving member, the moving member 4 can be pushed to the first position by applying a force in the direction opposite to the elastic force. Moreover, when the force in the direction opposite to the elastic force is removed, the elastic member 5 can timely reset the moving member 4 to the second position. Therefore, during the disassembly and assembly process of the connecting seat 2 and the positioning seat 1 each time, only the second driving member needs to be operated.

[0047] In another embodiment of the present application, please refer to Figure 3 and Figure 4 , the second driving member is a pneumatic device (not shown in the figure). The moving member 4 includes a pushing portion 40 and a blocking portion 41 connected to each other. The pushing portion 40 can extend into the accommodating groove 11 and abut against the detent 12. The blocking portion 41 is accommodated in the moving groove 13 and blocks the communication port between the moving groove 13 and the accommodating groove 11, so that the moving groove 13 forms a closed groove. The pneumatic device is connected to the positioning seat 1, and the pneumatic device communicates with the moving groove 13.

[0048] By using the blocking portion 41 to form a closed groove for the moving groove 13, under the action of the pneumatic device, air pressure can be formed inside the moving groove 13, and the air pressure pushes the moving member 4 to move.

[0049] Specifically, the blocking portion 41 divides the moving groove 13 into a first closed side 130 and a second closed side 131. Along the first direction, the accommodating groove 11 is located on the side of the moving groove 13 close to the first closed side 130. When the moving member 4 moves to the first position, the blocking portion 41 is located on the first closed side 130, and the pushing portion 40 withdraws from the accommodating groove 11, and the detent 12 can roll into the accommodating groove 11. When the moving member 4 moves to the second position, the blocking portion 41 is located on the second closed side 131. Therefore, the pushing portion 40 extends into the accommodating groove 11 and pushes the detent 12 to extend into the positioning slot 10.

[0050] The aforementioned elastic member 5 is installed on the second closed side 131 of the moving groove 13. One end of the elastic member 5 is connected to the blocking portion 41, so that the elastic force of the elastic member 5 can drive the blocking portion 41 to move toward the first closed side 130.

[0051] Therefore, to enable the ball 12 to roll into the receiving groove 11, it is necessary to move the blocking portion 41 toward the second sealed side 131. An air passage 14 is provided in the positioning seat 1, and the air passage 14 communicates with the moving groove 13 and the pneumatic device. Specifically, the air passage 14 communicates with the first sealed side 130 of the moving groove 13. At this time, the moving groove 13 is ventilated by the pneumatic device, and a positive pressure is formed on the first sealed side 130, driving the blocking portion 41 to move toward the second sealed side 131. In some other embodiments, the air passage 14 can also be arranged to communicate with the second sealed side 131 of the moving groove 13. At this time, the moving groove 13 is sucked by the pneumatic device, and a negative pressure is formed on the second sealed side 131, driving the blocking portion 41 to move toward the second sealed side 131.

[0052] In another embodiment of the present application, please refer back to Figure 1 and Figure 2 , two spaced-apart protrusions 21 are provided on the side of the connecting seat 2 away from the positioning seat 1. A mating seat 22 is fixedly connected to each of the two protrusions 21. A strip-shaped notch 220 is provided on the side of the mating seat 22 close to the protrusion 21 to cooperate with the protrusion 21 to form a sliding groove 23. A slider 310 is provided on the clamping block 31, and the slider 310 is slidably connected to the corresponding sliding groove 23. Through the cooperation of the slider 310 and the sliding groove 23, the rotation of the clamping block 31 is restricted and a guiding effect is provided for the sliding of the clamping block 31.

[0053] In another embodiment of the present application, please refer to Figure 1 and Figure 5 , two convex rings 301 are provided on the circumference of the screw 30, and the two convex rings 301 are spaced apart along the second direction. A U-shaped block 24 is fixedly connected to the connecting seat 2. The U-shaped groove of the U-shaped block 24 faces the connecting seat 2 and is sleeved on the screw 30, and the U-shaped block 24 is stuck between the two convex rings 301. Since the U-shaped block 24 is fixedly connected to the connecting seat 2, the movement of the screw 30 along the second direction can be restricted through the cooperation of the U-shaped block 24 and the two convex rings 301, thereby ensuring that the rotational movement of the screw 30 is converted into a linear movement of the clamping block 31.

[0054] Please refer to Figure 1 , the present application also provides a processing system, the processing system includes a processing machine tool 1000 and the workpiece processing and clamping mechanism provided by the embodiment of the present application, and the positioning seat 1 is fixedly installed on the processing machine tool 1000.

[0055] The processing system provided by this application adopts the workpiece processing and clamping mechanism provided by the embodiments of this application. By fixedly installing the positioning seat 1 in the workpiece processing and clamping mechanism on the machine tool 1000, the positioning slot 10 of the positioning seat 1 and the positioning pin 20 of the connecting seat 2 can play a positioning role in the disassembly and assembly of the clamping component 3. The clamping component 3 drives the two clamping blocks 31 to move away from each other or move closer to each other by rotating the same screw 30, thereby being able to center the workpiece in the clamping groove 32 and ensuring the processing position of the workpiece on the machine tool 1000. Therefore, whether only disassembling and assembling parts or disassembling and assembling the overall clamping component 3, the assembly position can be accurately ensured, and it has high repeat positioning characteristics.

[0056] The foregoing 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 within the protection scope of this application.
