Therefore, they should not be construed as limitations on this utility model.
[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0032] Please see Figure 1-4 A worktable suitable for clamping irregularly shaped workpieces includes a tabletop 1. At least three sets of fixed bases 2 are provided on the upper end of the tabletop 1. A processing table 5 that can be raised and lowered by a pneumatic push rod 7 is provided in the center of the tabletop 1. The fixed bases 2 are symmetrically distributed about the central axis of the processing table 5. Each fixed base 2 includes a base 21 fixed to the tabletop 1, a first support block 22 fixed above the base 21, and a second support block 23. The first support block 22 is located on the side of the second support block 23 away from the processing table 5. A threaded rod 3 is threadedly connected to the first support block 22, and a clamping assembly 4 is slidably provided on the second support block 23. All clamping assemblies 4 are used to clamp the workpiece together. The clamping assembly 4 includes an end block 42, a mounting block 43, a clamping part, and two round rods 41. The two round rods 41 are inserted and slidably mounted on the second support block 23. The end block 42 is fixed to the end near the threaded rod 3, and the mounting block 43 is fixed to the end away from the threaded rod 3. The clamping part is rotatably connected to the mounting block 43.
[0033] In this embodiment, the thread direction of the threaded rod 3 and the sliding direction of the clamping assembly 4 are both perpendicular to the central axis of the processing table 5.
[0034] It should be noted that this design allows the rotation of the threaded rod 3 to be directly converted into the linear motion of the clamping assembly 4 in the direction perpendicular to the central axis of the processing table 5. This ensures that when the clamping assembly 4 applies clamping force to the workpiece, the direction of the force is along the direction in which the workpiece needs to be fixed. This is beneficial for achieving stable and accurate clamping and avoids unnecessary displacement or tilting of the workpiece during processing due to deviation in the direction of the force.
[0035] In this embodiment, the threaded rod 3 is rotatably engaged with the end block 42 on the side near the processing table 5, and the clamping assembly 4 can be slid by rotating the threaded rod 3.
[0036] It should be noted that the rotating snap-fit design means that when the threaded rod 3 rotates, the end block 42 will not rotate with the threaded rod 3. Instead, under the threaded pushing action of the threaded rod 3, it can drive the entire clamping assembly 4 to slide along the second support block 23. It can also slide in the opposite direction. This structure is simple and reliable. By rotating the threaded rod 3, the position of the clamping assembly 4 can be precisely controlled, so as to achieve clamping and adjustment of irregular workpieces of different sizes and shapes.
[0037] In this embodiment, the clamping assembly 4 further includes a fastening bolt 45, which is threadedly connected to the mounting block 43 and its end abuts against the clamping part.
[0038] It should be noted that the fastening bolt 45 allows the rotation angle of the clamping part on the mounting block 43 to be fixed, further ensuring the stability of the clamping.
[0039] In this embodiment, the clamping part includes a triangular block 441, on which a rotating shaft 444 is provided to cooperate with the mounting block 43. Two elliptical wheels 443 are rotatably connected to the three sides of the triangular block 441, and an annular groove 442 is also provided on the side of the triangular block 441.
[0040] It should be noted that all three sides of the triangular block 441 can be used to contact the workpiece. The elliptical wheel 443, which is rotatably connected to the three sides of the triangular block 441, can automatically adjust its angle according to the shape of the workpiece surface, better conforming to the workpiece surface and providing a uniform clamping force. The annular groove 442 reduces the weight of the triangular block 441 and increases the rotation space of the elliptical wheel 443, further improving the stability of clamping.
[0041] In this embodiment, a cleaning hole 11 is provided on the desktop 1, and a cleaning plate 6 is rotatably connected to the bottom of the desktop 1. A cleaning hole 2 with the same size as the cleaning hole 11 is provided on the cleaning plate 6, and the cleaning hole 11 has a chamfer 12.
[0042] It should be noted that the opening and closing of cleaning holes 11 and 2 can be controlled by rotating the cleaning disc 6. When cleaning the desktop 1, rotating the cleaning disc 6 aligns cleaning holes 11 and 2, allowing debris and other waste on the desktop 1 to fall through them. The beveled angle 12 of cleaning hole 11 helps guide debris smoothly into the cleaning hole, preventing it from accumulating at the edge.
[0043] In this embodiment, the cleaning tray 6 is provided with a circular hole 62 in the middle that allows the processing table 5 to pass through, and anti-slip strips are provided on the side of the cleaning tray 6.
[0044] It should be noted that the circular hole 62 in the middle of the cleaning disc 6 ensures that the processing table 5 can rise and fall normally under the action of the pneumatic push rod 7 without interfering with the cleaning disc 6. The anti-slip strips on the side of the cleaning disc 6 increase the friction when the operator rotates the cleaning disc 6, making the operation more convenient and labor-saving, and easily controlling the opening and closing state of the first cleaning hole 11 and the second cleaning hole.
[0045] In summary, this worktable, suitable for clamping irregularly shaped workpieces, achieves stable and precise clamping of various irregularly shaped workpieces through at least three symmetrically distributed fixed bases 2 and clamping components 4 on them. The clamping components 4 can flexibly and adaptively adjust according to the shape of the workpiece, effectively avoiding workpiece displacement or shaking during processing, thereby significantly improving processing accuracy and efficiency and meeting the diverse needs of the machining field.
[0046] This worktable, suitable for clamping irregularly shaped workpieces, features a rotatable cleaning disc 6 at the bottom of the tabletop 1. The opening and closing of cleaning holes 11 and 2 enables rapid cleaning of the worktable. The anti-slip strips and central circular hole 62 on the cleaning disc 6 ensure both ease of operation and normal lifting and lowering of the machining table 5, providing a clean and efficient working environment for machining.
[0047] The working principle of this worktable, suitable for clamping irregularly shaped workpieces, is as follows:
[0048] The irregularly shaped workpiece is placed on the processing table 5. According to the shape and size of the workpiece, the threaded rods 3 on each fixed base 2 are rotated. Since the threaded rods 3 are threadedly connected to the first support block 22 and are rotatably engaged with the end block 42 of the clamping assembly 4, rotating the threaded rods 3 will drive the clamping assembly 4 to slide along the second support block 23. Multiple clamping assemblies 4 move closer to the workpiece together to perform initial positioning of the workpiece.
[0049] During clamping, the triangular block 441 of the clamping part automatically adjusts its angle according to the shape of the workpiece surface, and the elliptical wheels 443 on its three sides conform to the workpiece surface. After adjusting the angle, tighten the fastening bolts 45 to fix the clamping part, ensuring stable clamping and preventing the workpiece from shifting or shaking during processing, thereby ensuring processing accuracy.
[0050] After processing, the desktop 1 needs to be cleaned. The operator holds the anti-slip strip on the side of the cleaning disc 6 and rotates the cleaning disc 6 to align the second cleaning hole with the first cleaning hole 11. Debris and other debris on the desktop 1 can then fall through these two holes, achieving rapid cleaning. After cleaning, the cleaning disc 6 is rotated again to offset the two holes, closing the cleaning channel. The round hole 62 in the middle of the cleaning disc 6 ensures that the processing table 5 can be raised and lowered normally under the action of the pneumatic push rod 7, facilitating subsequent workpiece clamping and processing operations.
[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
