Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0038] In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the positions or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limitations of the present utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or a transmission connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements.

[0039] Example 1, reference Figure 1-7 The utility model proposes a clamping assembly for clamping a workpiece, comprising: a base A, a transmission part 1 and a support member 2, wherein the transmission part 1 and the support member 2 are arranged on the base A, and the support member 2 can move under the drive of the transmission part 1.

[0040] The transmission part 1 may be a cylinder, a motor screw slider mechanism, etc. The transmission part 1 may be used to drive the support member 2 to move laterally, and the support member 2 may be a support plate.

[0041] The first clamping member 3 is disposed on the supporting member 2 .

[0042] The second clamping member 4 is movably arranged on the supporting member 2 and can be close to or away from the first clamping member 3. The second clamping member 4 cooperates with the first clamping member 3 to clamp the workpiece; the first clamping member 3 and the second clamping member 4 can be clamping blocks, which cooperate with each other to clamp the workpiece.

[0043] The elastic mechanism 5 is used to apply a force to the second clamping member 4 to move it closer to the first clamping member 3 ; the elastic mechanism 5 is used to apply an elastic force to the second clamping member 4 toward the first clamping member 3 .

[0044] The movable mechanism B is movably arranged on the support member 2.

[0045] The limiting member 6 is arranged on the base A, and the limiting member 6 is arranged on the moving path of the movable mechanism B. When the movable mechanism B moves to contact with the limiting member 6, the movable mechanism drives the second clamping member 4 to move away from the first clamping member 3.

[0046] In this embodiment, the limiting member 6 has a first matching surface 601 that matches with the movable mechanism.

[0047] Activity Organization B includes:

[0048] The first rotating shaft 7 and the first rod 8 are rotatably connected to the supporting member 2 via the first rotating shaft 7 . The first rod 8 has a first end 801 and a second end 802 distributed on both sides of the first rotating shaft 7 . The first rod 8 can rotate.

[0049] The matching piece 9 is arranged at the first end 801. When the matching piece 9 moves to contact the first matching surface 601, the first rod 8 rotates around the first rotating shaft 7, and the second end 802 causes the second clamping piece 4 to move away from the first clamping piece 3. The matching piece 9 can be a column, and can be integrally formed with the first rod 8, or can be a separate component.

[0050] Furthermore, in this embodiment, the activity mechanism B also includes:

[0051] A second rotating shaft 10 and a second rod 11. The second rod 11 is rotatably connected to the support member 2 via the second rotating shaft 10. The second rod 11 has a third end 1101 and a fourth end 1102 distributed on both sides of the second rotating shaft 10. The third end 1101 is located on the moving path of the second end 802. A first force arm L1 is formed between the contact point between the third end 1101 and the second end 802 and the axis of the second rotating shaft 10. The fourth end 1102 is used to abut against the second clamping member 4 to drive the second clamping member 4 away from the first clamping member 3. A second force arm L2 is formed between the contact point between the fourth end 1102 and the second clamping member 4 and the axis of the second rotating shaft 10, wherein the first force arm L1 is greater than the second force arm L2.

[0052] The transmission part 1 drives the support member 2 to move toward the limiting member 6, and when the matching member 9 contacts the first matching surface 601, the matching member 9 is connected to the first matching surface 601. Figure 6 , the matching member 9 drives the first rod 8 to rotate counterclockwise, squeezes the third end 1101 through the second end 802, drives the second rod 11 to rotate, and squeezes the second clamping member 4 with the fourth end 1102, overcomes the elastic force of the elastic mechanism 5, and makes the second clamping member 4 move away from the first clamping member 3. At this time, the workpiece, such as the stamp material, can be placed between the first clamping member 3 and the second clamping member 4.

[0053] The transmission part 1 is then used to drive the support member 2 to move away from the limiting member 6. After the matching member 9 is separated from the first matching surface 601, the elastic mechanism 5 uses elastic force to drive the second clamping member 4 to approach the first clamping member 3 to clamp the workpiece, thereby facilitating the processing of the workpiece.

[0054] After the re-processing is completed, the second clamping member 4 is moved away from the first clamping member 3 again, and the workpiece is taken out.

[0055] In this embodiment, by making the first force arm L1 greater than the second force arm L2, the transmission part 1 can use a relatively small force to drive the second clamping member 4 to overcome the elastic force of the elastic mechanism 5 and move the second clamping member 4 away from the first clamping member 3. A transmission part 1 with relatively small power can be selected, which can save energy consumption and reduce costs.

[0056] In this embodiment, by configuring the elastic mechanism 5, the limiting member 6, the movable mechanism, etc., the second clamping member 4 can be driven away from or close to the first clamping member 3 during the movement of the supporting member 2 by the transmission part 1, so as to place the workpiece, clamp the workpiece, take out the workpiece, etc., reduce manual operations, be more automated, and be more convenient to use.

[0057] Furthermore, in this embodiment, the clamping assembly further includes a blocking member 12, which is located on the support member 2 and on the side of the second end 802 away from the third end 1101. The second end 802 is located between the blocking member 12 and the third end 1101 to ensure that the second end 802 can smoothly squeeze the third end 1101, avoid accidents, and ensure the stability of production and processing.

[0058] Furthermore, the support member 2 is provided with a fixing member 13, and the fixing member 13 is provided with a slide groove 1301, wherein the second clamping member 4 is slidably connected with the slide groove 1301, and the second clamping member 4 has a contact portion 403 for abutting and cooperating with the movable mechanism. The second clamping member 4 can slide along the slide groove 1301. The contact portion 403 cooperates with the fourth end 1102, and is driven away from the first clamping member 3 by the fourth end 1102.

[0059] Furthermore, the elastic mechanism 5 includes a support column 501 and a spring 502 on the support column 501. The support column 501 is connected to the fixing member 13. One end of the spring 502 is connected to the second clamping member 4, and the other end is connected to the fixing member 13. The spring 502 is used to apply elastic force to the second clamping member 4.

[0060] Furthermore, a first clamping groove 301 in a "V" shape is provided on the first clamping member 3, and a second clamping groove 302 in a "V" shape is provided on the second clamping member 4, and the second clamping groove 302 matches the first clamping groove 301. The first clamping groove 301 and the second clamping groove 302 can be used to clamp a rectangular workpiece, such as a rectangular wooden block.

[0061] This embodiment can be applied to an engraving machine, etc., for seal processing.

[0062] In this embodiment, two movable mechanisms and two limiting members 6 are provided, and the two movable mechanisms and the two limiting members 6 are arranged on both sides of the second clamping member 4 respectively.

[0063] By providing two movable mechanisms and two limiting members 6, a force is applied to the second clamping member 4 from both sides, so that the second clamping member 4 can move more smoothly and clamp the workpiece better.

[0064] Combination Figure 6 The first mating surface 601 located at the lower right corner is an inclined surface, and an acute angle is formed between the first mating surface 601 and the moving direction of the support member 2; the first mating surface 601 located at the upper left corner is perpendicular to the moving direction of the support member 2.

[0065] Embodiment 2, combined Figure 8 Compared with the embodiment 1, this embodiment includes a movable mechanism and a limiting member 6, wherein the first mating surface 601 is an inclined surface, and an acute angle is formed between the first mating surface 601 and the moving direction of the support member 2. The mating member 9 can be moved along the first mating surface 601, and the inclined surface can be used to drive the mating member 9 to rotate.

[0066] Embodiment 3, compared with embodiment 1, the second rotating shaft 10 and the second rod 11 are not provided in this embodiment, but the second end 802 is used to drive the second clamping member 4 to move. Of course, the inclination direction of the first mating surface 601 should be changed symmetrically, so that when the mating member 9 contacts the first mating surface 601, it can drive the first rod 8 to rotate clockwise, and use the second end 802 to drive the second clamping member 4 away from the first clamping member 3.

[0067] In this embodiment, a relatively large power transmission part 1 can be used.

[0068] Embodiment 4, combined Fig. 9 A processing device includes the clamping assembly, a processing head 14, and a moving mechanism 15 as described in Embodiment 1, 2, or 3. The moving mechanism 15 is used to drive the processing head 14 to process the workpiece clamped by the clamping assembly. The processing device can be an engraving machine. The transmission part 1 can drive the support member 2 to move along the X direction, and the moving mechanism 15 can drive the processing head 14 to move along the Y and Z directions.
