[0031] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.

[0032] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] It should be noted that when a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there can be a central component; when an component is considered to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time; when an component is considered to be "installed on" another component, it can be directly installed on the other component or there can be a central component at the same time. When an component is considered to be "set on" another component, it can be directly set on the other component or there can be a central component at the same time.

[0034] like Figures 1 to 3As shown, a mobile clamping device 100 includes a first support assembly 1 and a second support assembly 2. The first support assembly 1 has a first support seat 11 and a locking assembly 12. The first support seat 11 is provided with a guide groove 111. The second support assembly 2 is at least partially located in the guide groove 111 and slides with the first support seat 11 in a first direction. The locking assembly 12 is movably installed in the first support assembly 1, and the locking assembly 12 is used to abut against the outer wall of the second support assembly 2. By providing the guide groove 111 on the first support seat 11, the second support assembly 2 is at least partially located in the guide groove 111 and slides with the first support seat 11 in the first direction. The guide groove 111 is used to limit the moving direction of the second support assembly 2, thereby improving the stability of the second support assembly 2 when moving. The first support seat 11 is used to support the second support assembly 2, and the second support assembly 2 is used to clamp or fix the workpiece. When the workpiece is moved to a preset position through the second support assembly 2, the locking assembly 12 is used to abut against the outer wall of the second support assembly 2 and fix the position of the second support assembly 2 on the first support seat 11, thereby improving the stability of the second support assembly 2 in clamping the workpiece. With this arrangement, there is no need to move the workpiece by adjusting the machine tool, thereby improving the problem that the workpiece cannot be moved and adjusted on the machine tool.

[0035] like Figure 2 As shown, the locking assembly 12 includes a first driving member 124 and a first fixed block 121. The first fixed block 121 is installed in the first support seat 11 and slidably cooperates with the inner wall of the first support seat 11 in the second direction; the first driving member 124 is rotatably installed on the first support seat 11, and the first fixed block 121 is sleeved on the first end of the first driving member 124 and threadedly cooperates with the outer wall of the first driving member 124. In the transmission direction of the first driving member 124, the inner wall of the first support seat 11 is used to abut against the first fixed block 121, and the second end of the first driving member 124 is used to abut against the inner wall of the first support seat 11; the first direction intersects with the second direction. When the second support assembly 2 moves to the preset position, a tool is inserted into the first adjustment hole 125 to drive the first driving member 124 to rotate. Since the first fixing block 121 is limited by the inner wall of the first support seat 11 in the rotation direction of the first driving member 124, a friction force is generated between the inner wall of the first fixing member 121 and the outer wall of the first driving member 124. This friction force drives the first fixing member 121 to move toward the inside of the second support assembly 2 and abuts against the outer wall of the second support assembly 2, thereby fixing the position of the second support assembly 2 on the guide groove 111, further improving the stability of the second support assembly 2 on the supported workpiece. Moreover, this locking assembly 12 can be set to two groups as needed, and the two groups of locking assemblies 12 are respectively located on both sides of the second support assembly 2. In this embodiment, the first direction is the direction of horizontal movement of the workpiece.

[0036] like Figure 2 As shown, the locking assembly 12 also has a second fixed block 122 and a transmission block 123, the first fixed block 121 is sleeved on the outside of the transmission block 123, and the transmission block 123 is abutted against the first fixed block 121, the transmission block 123 is sleeved on the first end of the first driving member 124, and is threadedly matched with the first driving member 124; the second fixed block 122 is sleeved on the second end of the first driving member 124, and is abutted against the first driving member 124; the first fixed block 121 and the second fixed block 122 are staggered in the circumferential direction of the second supporting assembly 2, and the first fixed block 121 and the second fixed block 122 are used to abut against the outer wall of the second supporting assembly 2. In this embodiment, the transmission block 123 is sleeved on the first end of the first driving member 124 and is threadedly matched with the first driving member 124. Since the second fixing block 122 is sleeved on the second end of the first driving member 124 and abuts against the first driving member 124, when the first driving member 124 rotates, the transmission block 123 is driven to move toward the second support assembly 2. The transmission block 123 transmits power to push the first fixing block 121 and the second fixing block 122 to approach each other toward the second support assembly 2, and at the same time abut against the second support assembly 2, further improving the stability of the second support assembly 2 in clamping the workpiece. Moreover, the first fixing block 121 and the second fixing block 122 are staggered in the circumferential direction of the second support assembly 2, so that the first fixing block 121 and the second fixing block 122 apply pressure from different directions to fix the second support assembly 2.

[0037] In order to improve the stability of the first fixing block 121 or the second fixing block 122 moving in the second direction. Figure 2 As shown, a first limiting groove 1211 is provided on the first fixing block 121 or the second fixing block 122, and the first limiting groove 1211 is extended along the second direction; the first supporting seat 11 has a first limiting block 126 that is slidably matched with the first limiting groove 1211. The first limiting block 126 is matched with the first limiting groove 1211, and the first limiting groove 1211 is extended along the second direction. When the first fixing block 121 or the second fixing block 122 moves, it is limited by the first limiting block 126, thereby improving the stability of the first fixing block 121 or the second fixing block 122 moving in the second direction.

[0038] like Figure 1 and Figure 2As shown, the mobile clamping device 100 further includes a first support member 13, a second support member 24, and a sliding support seat 21. The first support member 13 is mounted on the first support seat 11, and the second support member 24 is mounted on the sliding support seat 21, and the first support member 13 and the second support member 24 are arranged opposite to each other; the sliding support seat 21 has a guide block 211 that cooperates with the guide groove 111. In this embodiment, the first support member 13 is used to connect another clamping device 100 or a base, the second support member 24 is used to fix a workpiece or connect another clamping device 100, the first support seat 11 is used to support the first support member 13, and the sliding support seat 21 is used to support the second support member 24. The sliding support seat 21 is slidably matched with the guide groove 111 in the first direction through the guide block 211.

[0039] like Figure 3 and Figure 4 As shown, the mobile clamping device 100 further includes a second support seat 23 and a clamping assembly 22, wherein the clamping assembly 22 is installed in the second support seat 23, and the second support seat 23 is installed on the sliding support seat 21; the second support member 24 is at least partially located in the clamping assembly 22, and the clamping assembly 22 is used to remove or install the second support member 24. In this embodiment, the second support seat 23 is used to support the clamping assembly 22, so that the clamping assembly 22 is used to install or remove the second support member 24; when the sliding support seat 21 moves in the first direction, it will drive the second support seat 23, the clamping assembly 22, and the second support member 24 to move, thereby adjusting the position of the workpiece on the machine tool.

[0040] like Figure 4 and Figure 5As shown, the clamping assembly 22 includes a first clamping block 221, a second clamping block 222, a first clamping arm 223, a second clamping arm 224, and a second driving member 228, and the second driving member 228 is rotatably installed in the second supporting seat 23; the first clamping block 221 and the second clamping block 222 are slidably installed in the second supporting seat 23, and a clamping position 201 is formed between the first clamping block 221 and the second clamping block 222; the first clamping block 221 and the second clamping block 222 are respectively installed at the first ends of the first clamping arm 223 and the second clamping arm 224, the middle sections of the first clamping arm 223 and the second clamping arm 224 are rotatably matched with the second supporting seat 23, and the second ends of the first clamping arm 223 and the second clamping arm 224 are matched with the second driving member 228. In this embodiment, the second driving member 228 is used to drive the first clamping arm 223 and the second clamping arm 224 to move respectively, so that the first clamping arm 223 and the second clamping arm 224 simultaneously drive the first clamping block 221 and the second clamping block 222. When moving toward the clamping position 201, the first clamping block 221 and the second clamping block 222 are used to abut against the outer wall of the second support member 24, thereby fixing the position of the second support member 24 in the second support seat 23. In addition, the middle sections of the first clamping arm 223 and the second clamping arm 224 have a rotating shaft 225, and the rotating shaft 225 is rotatably matched with the second support seat 23. The first clamping arm 223 and the second clamping arm 224 can rotate in the second support seat 23. The first clamping arm 223 and the second clamping arm 224 are equivalent to a lever structure, thereby reducing the force of the second driving member 228 and improving the convenience of operation of the clamping assembly 22. The second driving member 228 can be driven to rotate by inserting a tool into the second adjustment hole 2284 . The second adjustment hole 2284 can be arranged on the outer surface of the sliding support seat 21 to facilitate the operator to adjust the clamping assembly 22 .

[0041] like Figure 5 and Figure 6 As shown, the clamping assembly 22 further includes a first driving block 226 and a second driving block 227, which are respectively mounted on the second ends of the first clamp arm 223 and the second clamp arm 224, and are respectively sleeved on the two ends of the second driving member 228; the first driving block 226 and the second driving block 227 are both threadedly engaged with the second driving member 228. The second driving member 228 is used to respectively drive the first driving block 226 and the second driving block 227 to approach or move away from each other, and the first driving block 226 and the second driving block 227 will drive the second ends of the first clamp arm 223 and the second clamp arm 224 to approach or move away from each other when moving, so that the first clamp arm 223 and the second clamp arm 224 rotate in the second support seat 23, and drive the first clamp block 221 and the second clamp block 222 to move toward the second support member 24, so as to clamp the second support member 24.

[0042] like Figure 6As shown, the two ends of the second driving block 227 have a first external thread 2281 and a second external thread 2282, respectively, and the thread directions of the first external thread 2281 and the second external thread 2282 are opposite; the first driving block 226 has a first internal thread matched with the first external thread 2281, and the second driving block 227 has a second internal thread matched with the second external thread 2282. By the first external thread 2281 being matched with the first internal thread, the second external thread 2282 being matched with the second internal thread, and the first external thread 2281 and the second external thread 2282 being matched with each other in opposite directions, the first driving block 226 and the second driving block 227 are brought closer to or farther away from each other when the second driving member 228 is rotated clockwise or counterclockwise.

[0043] like Figure 5 and Figure 6 As shown, the clamping assembly 22 further includes a second limit block 220 and a pin 229. The second limit block 220 is fixed in the second support seat 23 by the pin 229. The second limit block 220 has a protrusion 202, and the protrusion 202 is extended along the rotation direction of the second rotating member 228. The second driving member 228 has a second limit groove 2283 that cooperates with the protrusion 202. The second limit block 220 is used to limit the position of the second driving member 228 in the second support seat 23, and the second limit block 220 is fixed in the second support seat 23 by the pin 229; the protrusion 202 on the second limit block 220 cooperates with the second limit groove 2283 of the second driving member 228. When the second driving member 228 rotates, the protrusion 202 will limit the second driving member 228 from moving in the second support seat 23, so that the second driving member 228 can rotate stably in the second support seat 23, thereby improving the stability of the second driving member 228 in the second support seat 23.
