[0044] The content of the utility model will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the utility model more clearly and in detail.

[0045] Figure 1 Schematic diagram of the clamping device provided in the embodiment of the present application Figure 1 . Figure 2 Schematic diagram of the clamping device provided in the embodiment of the present application Figure 2 .

[0046] like Figure 1-Figure 2 As shown, this embodiment provides a clamping device 100, including: a base 110 and at least two clamping arms 120, the at least two clamping arms 120 are arranged one-to-one along a first direction (X direction) and at intervals on the base 110, and together with the base 110 form an adjustable clamping space 130, the clamping space 130 is used to clamp the workpiece 200 to be processed; the first end of the clamping arm 120 is rotatably connected to the base 110, and the second end of the clamping arm 120 is constructed to abut the workpiece 200 in the clamping space 130 along the second direction (Z direction); the second direction (Z direction) intersects with the first direction (X direction).

[0047] According to the clamping device 100 provided in this embodiment, the base 110 and the clamping arm 120 form a clamping space 130, and the workpiece 200 is stably clamped on the clamping device 100 through the cooperation of the clamping arm 120 and the base 110. In addition, the clamping arm 120 and the base 110 are rotatably connected, and the size of the clamping space 130 can be adjusted by adjusting the angle between the clamping arm 120 and the base 110. Such a clamping device 100 can adapt to workpieces 200 of different sizes. In this way, it is no longer necessary to adjust the position of the clamping device 100 on the milling machine, which saves clamping time and improves processing efficiency.

[0048] In an exemplary embodiment, the processing equipment corresponding to the clamping device 100 is connected together, and the clamping device 100 clamps the workpiece 200 to be processed so that the workpiece 200 remains stable during the processing. Specifically, the clamping device 100 includes a base 110, which is connected to the processing equipment and moves along the feeding direction of the processing equipment under the drive of the processing equipment.

[0049] In order to fix the workpiece 200 on the base 110, the clamping device 100 in this embodiment further includes at least two clamping arms 120, which correspond to each other one by one and are arranged at intervals along the first direction (X direction), and the clamping arms 120 and the base 110 are connected along the vertical direction (Z direction), and the clamping arms 120 and the base 110 together form a clamping space 130. In this way, the workpiece 200 is placed in the clamping space 130, and the workpiece 200 is stably clamped in the space through the joint action of the clamping arms 120 and the base 110, and the workpiece 200 is further processed by the processing equipment.

[0050] Furthermore, the first end of the clamping arm 120 is rotatably connected to the base 110. It can be understood that during the rotation of the two clamping arms 120 relative to the base 110, the two clamping arms 120 move closer to or farther from each other in the first direction (X direction), and the size of the clamping space 130 changes accordingly. In other words, the size of the clamping space 130 can be adjusted to accommodate workpieces 200 of different sizes, thereby increasing the applicable scope of the clamping device 100, saving the time spent on adjusting the connection between the clamping device 100 and the processing equipment, optimizing the installation process of the workpiece 200 processing, and further improving the processing efficiency of the workpiece 200.

[0051] During specific use, the workpiece 200 is placed on the base 110, the clamping arm 120 rotates relative to the base 110, and the second end of the clamping arm 120 abuts against the workpiece 200 along the second direction (Z direction) in the clamping space 130 to keep the workpiece 200 relatively stable along the second direction (Z direction).

[0052] It should be noted that, in this embodiment, the first direction (X direction) is along the feeding direction of the workpiece 200 , and the second direction (Z direction) is along the vertical direction (Z direction).

[0053] In some embodiments, the first end of the clamping arm 120 is rotatably connected to the end of the base 110 , and the second end of the clamping arm 120 rotates relative to the base 110 between above the end of the base 110 and above the clamping space 130 .

[0054] In this way, during the rotation of the clamping arm 120, the second end of the clamping arm 120 approaches the base 110, and the clamping arm 120 and the base 110 cooperate with each other to fix the workpiece 200 in the clamping space 130. The second end of the clamping arm 120 rotates toward the side away from the base 110, and the clamping space 130 becomes larger, which facilitates the loading and unloading of the workpiece 200.

[0055] The clamping arm 120 is disposed at the end of the base 110. It can be understood that the two clamping arms 120 in this embodiment are disposed at the two ends of the base 110 along the first direction (X direction). Correspondingly, the clamping arm 120a and the clamping arm 120b are opposite and spaced apart along the first direction (X direction), and the clamping arm 120a and the clamping arm 120b are both rotatably connected to the base 110. During the rotation of the clamping arm 120a relative to the base 110, the rotation range of the second end of the clamping arm 120a is between the upper end of the base 110 relative to the clamping arm 120a and the upper end of the clamping space 130. Similarly, during the rotation of the clamping arm 120b relative to the base 110, the rotation range of the second end of the clamping arm 120b is between the upper end of the base 110 relative to the clamping arm 120b and the upper end of the clamping space 130. In this way, the clamping arm 120 can adjust the size of the clamping space 130 during the rotation process, so that the clamping device 100 can adapt to workpieces 200 of different specifications.

[0056] In a specific embodiment, the first end of the clamping arm 120 and the base 110 are rotatably connected via a rotating shaft 140, and the rotating shaft 140 is parallel to the side edge of the base 110 and the corresponding side edge of the clamping arm 120. The clamping arm 120 and the base 110 are rotatably connected via a simple hole-shaft connection.

[0057] The top surface of the base 110 is provided with a connecting portion 150, and the connecting portion 150 protrudes from the top surface of the base 110 along the second direction (Z direction). The connecting portion 150 is provided with a through hole, which penetrates the opposite sides of the connecting portion 150 along the thickness direction of the connecting portion 150. The first end of the clamping arm 120 is also provided with a through hole. The through hole of the clamping arm 120 and the through hole of the connecting portion 150 are relatively penetrated along the thickness direction of the connecting portion 150, and the rotating shaft 140 is penetrated through the through hole of the clamping arm 120 and the through hole of the connecting portion 150, so that the clamping arm 120 can rotate relative to the base 110 through the rotating shaft 140.

[0058] It should be noted that the thickness direction of the connecting portion 150 in this embodiment is parallel to the side edges of the base 110 and the clamping arm 120 , that is, the axial extension direction of the rotating shaft 140 is parallel to the side edges of the base 110 and the clamping arm 120 .

[0059] In some embodiments, at least two clamping arms 120 form two clamping arm groups, each clamping arm group includes at least one clamping arm 120 , and the two clamping arm groups are symmetrically arranged relative to the base 110 .

[0060] It can be understood that when there are two clamping arms 120, the clamping arm 120a and the clamping arm 120b are opposite and spaced along the first direction (X direction), the clamping arm 120a can be used as a clamping arm group, and the clamping arm 120b can be used as a clamping arm group, and the two clamping arm groups are symmetrical relative to the base 110 along the first direction (X direction).

[0061] When there are multiple clamping arms 120 , the multiple clamping arms 120 can be equally divided into two clamping arm groups, and the two clamping arm groups are symmetrically arranged on the base 110 along the first direction (X direction).

[0062] Furthermore, when there are multiple clamping arms 120 in the clamping arm group, the multiple clamping arms 120 are arranged in sequence along the third direction, and the rotation planes of the clamping arms 120 are parallel to each other; the third direction is perpendicular to the first direction (X direction) and the second direction (Z direction). The multiple clamping arms 120 of the two clamping arm groups can make the clamping of the workpiece 200 more stable.

[0063] When there are multiple clamping arms 120, the multiple clamping arms 120 are equally divided into two clamping arm groups, and each clamping arm group has at least two clamping arms 120. For example, each clamping arm group has two clamping arms 120, or each clamping arm group has three clamping arms 120, etc. This embodiment does not specifically limit the number of clamping arms 120 in each clamping arm group.

[0064] Exemplarily, the multiple clamping arms 120 in each clamping arm group are arranged in sequence along the third direction. And the second end of each clamping arm 120 abuts against the workpiece 200 in the clamping space 130 along the second direction (Z direction) to keep the workpiece 200 stable. It is not difficult to understand that the multiple clamping arms 120 are arranged in sequence along the third direction, on the one hand, to enlarge the clamping space 130, and accordingly, the clamping space 130 of the clamping device 100 can accommodate workpieces 200 with larger structural dimensions. Furthermore, the two clamping arm groups are symmetrical relative to the base 110 along the first direction (X direction), and the multiple clamping arms 120 in each clamping arm group abut against the workpiece 200, which increases the effective contact area between the workpiece 200 and the clamping arm 120, so that the clamping device 100 clamps the workpiece 200 more firmly and stably.

[0065] It should be noted that the two symmetrically arranged clamping arm groups can prevent the workpiece 200 from being disconnected from the clamping device 100 during the processing, thereby improving the stability and efficiency of the processing. When clamping the workpiece 200, the two symmetrically arranged clamping arm groups can ensure the symmetry of the workpiece 200 on the clamping device 100, thereby ensuring that the two relative planes to be processed of the workpiece 200 along the third direction can be processed by the tool of the processing equipment, thereby improving the processing quality of the workpiece 200.

[0066] In addition, in this embodiment, the rotation planes of the multiple clamping arms 120 in the same clamping arm group are parallel to each other. Furthermore, in this embodiment, the first direction (X direction) is along the feeding direction of the workpiece 200, the second direction (Z direction) is along the vertical direction (Z direction), the second direction (Z direction) is perpendicular to the first direction (X direction), and the third direction is perpendicular to the first direction (X direction) and the second direction (Z direction).

[0067] On the basis of the above-mentioned embodiment, the clamping device 100 further includes a driving assembly, which is connected to the clamping arm 120 in a one-to-one correspondence, and the driving assembly drives the clamping arm 120 to rotate. The driving assembly can provide a mechanical driving force to rotate the clamping arm 120 relative to the base 110, and drive the second end of the clamping arm 120 to maintain contact with the workpiece 200 in the clamping space 130.

[0068] For example, the driving assembly may output linear motion to drive the clamping arm 120 to rotate relative to the base 110, or the driving assembly may output circular motion to drive the clamping arm 120 to rotate relative to the base 110. This embodiment does not specifically limit this.

[0069] In an optional embodiment, the driving assembly includes a telescopic member 160, the first end of the telescopic member 160 is rotatably connected to the base 110, and the second end of the telescopic member 160 is rotatably connected to a side of the clamping arm 120 close to the second end; the telescopic member 160 drives the clamping arm 120 to rotate. In this way, the telescopic member 160 and the clamping arm 120 form a structure similar to a mechanical joint arm, and the linear motion output by the telescopic member 160 drives the clamping arm 120 to rotate relative to the base 110.

[0070] It can be understood that the first end of the telescopic member 160 is rotatably connected to the base 110, and the second end of the telescopic member 160 is rotatably connected to the clamping arm 120. The telescopic member 160 can push the clamping arm 120 to rotate relative to the base 110 by telescoping, and during the rotation of the clamping arm 120, the telescopic member 160 also rotates relative to the base 110.

[0071] The first end of the telescopic member 160 in this embodiment is a fixed end, and the second end of the telescopic member 160 is a telescopic end. The second end of the telescopic member 160 extends relative to the first end of the telescopic member 160, and the length of the telescopic member 160 is relatively increased. The telescopic member 160 pushes the clamping arm 120 to rotate relative to the base 110, and the second end of the clamping arm 120 moves into the clamping space 130 and abuts against the workpiece 200 along the second direction (Z direction) in the clamping space 130.

[0072] After the second end of the clamping arm 120 abuts against the workpiece 200, the working state of the telescopic member 160 remains unchanged. It can be understood that the mechanical driving force provided by the telescopic member 160 causes the second end of the clamping arm 120 to continue to abut against the workpiece 200, ensuring that the workpiece 200 is clamped stably during the feeding process, and further preventing the workpiece 200 from having position deviation during the feeding process, thereby improving the processing quality of the workpiece 200 and reducing the probability of processing waste.

[0073] When the workpiece 200 is processed, the clamping device 100 drives the workpiece 200 to restore the initial feeding position, the second end of the telescopic member 160 contracts, and the telescopic member 160 drives the clamping arm 120 to rotate relative to the base 110. The second end of the clamping arm 120 and the workpiece 200 are disengaged and moved outside the clamping space 130 to facilitate the staff to remove the workpiece 200 from the clamping device 100. At the same time, it prevents the clamping arm 120 and the workpiece 200 from interfering with each other and colliding during the transportation of the workpiece 200, resulting in damage to the surface of the workpiece 200, thereby improving the processing efficiency and yield rate of the workpiece 200.

[0074] Exemplarily, the telescopic member 160 may be an electric push rod, a pneumatic push rod, or a hydraulic push rod, which is not specifically limited in this embodiment.

[0075] Specifically, when the telescopic member 160 is a hydraulic push rod, the hydraulic control system of the telescopic member 160 can be connected to the hydraulic control system of the processing equipment, so that the telescopic member 160 and the hydraulic control system of the processing equipment are unified, the integration is improved, and the telescopic change of the telescopic member 160 is more stable and accurate through the hydraulic control. In this way, the production and use costs of the clamping device 100 are further reduced, and accordingly, the processing cost of the workpiece 200 is also reduced.

[0076] In some embodiments, the clamping arm 120 includes a first portion 121 and a second portion 122 connected to each other, the first portion 121 is connected to the base 110, and the end of the second portion 122 away from the first portion 121 is configured to abut against the workpiece 200 in the clamping space 130; the extension direction of the second portion 122 and the extension direction of the first portion 121 have an included angle. Such a clamping arm 120 forms a certain avoidance space by connecting the first portion 121 and the second portion 122 to each other, further increasing the clamping space 130 to clamp workpieces 200 of different sizes. At the same time, the first portion 121 and the second portion 122 have an included angle, which facilitates the loading and unloading of the workpiece 200, and during the process of loading and unloading the workpiece 200, the clamping arm 120 and the workpiece 200 will not interfere with each other, thereby preventing the workpiece 200 from being mechanically damaged, improving the processing yield and processing efficiency, and further, can effectively avoid safety accidents caused by the interference between the clamping arm 120 and the workpiece 200.

[0077] It should be noted that there is an angle between the extension direction of the first portion 121 and the extension direction of the first portion 121, and the angle is not specifically limited in this embodiment. The angle between the first portion 121 and the second portion 122 can be selected according to actual production conditions.

[0078] Furthermore, the clamping device 100 further includes a fastener 170 , which is rotatably connected to the second end of the clamping arm 120 , and the clamping arm 120 abuts against the workpiece 200 via the fastener 170 .

[0079] Exemplarily, the fastener 170 in this embodiment can be a shaft, and the axis of the shaft is parallel to the axis of the rotating shaft 140 of the clamping arm 120. In this way, the fastener 170 is rotatably connected to the second end of the clamping arm 120, and the clamping arm 120 rotates relative to the base 110, driving the fastener 170 to approach or move away from the workpiece 200, and the clamping arm 120 abuts against the workpiece 200 through the fastener 170. It can be understood that the area where the fastener 170 and the workpiece 200 abut each other is relatively large, so that the clamping device 100 can achieve stable clamping of the workpiece 200.

[0080] It should be noted that, in some embodiments, the length of the workpiece 200 is 3500 mm-4200 mm, and the width is 450 mm-820 mm. Of course, the length and width of the workpiece 200 can be less than or greater than this range. The workpiece 200 can be a carbon block, but is not limited to a carbon block.

[0081] The clamping device 100 provided in this embodiment includes: a base 110 and at least two clamping arms 120, at least two clamping arms 120 are arranged one by one along a first direction (X direction) and are spaced apart on the base 110, and together with the base 110, form an adjustable clamping space 130, and the clamping space 130 is used to clamp the workpiece 200 to be processed; the first end of the clamping arm 120 is rotatably connected to the base 110, and the second end of the clamping arm 120 is configured to abut against the workpiece 200 in the clamping space 130 along a second direction (Z direction); the second direction (Z direction) intersects with the first direction (X direction). Such a clamping device 100 can clamp workpieces 200 of various sizes, is easy to operate, and improves processing efficiency.

[0082] In addition, an embodiment of the present application may also provide a processing equipment, including: a workbench and the clamping device 100 in any of the aforementioned embodiments; the clamping device 100 is connected to the workbench.

[0083] It should be noted that the processing equipment in this embodiment may be a milling machine, but is not limited to a milling machine. Such processing equipment can improve the processing efficiency of the workpiece 200.
