Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and specifically to a multifunctional clamping device. Background Technology

[0002] In the process of CNC machining center, in order to prevent the workpiece (this application is for machining rectangular workpieces) from shifting in position during the machining process, which would lead to machining failure, it is necessary to clamp the workpiece. During the clamping process, a clamping device is required to clamp and fix it.

[0003] During the clamping process, the clamp is usually fixed by clamping from both sides. This method limits the overall fixation to the pressure on both sides. The clamping effect is not stable. When force is applied from other directions, the position is very easy to move, which affects the clamping effect and is very inconvenient.

[0004] To address the aforementioned problems, this application proposes a multifunctional clamping device. Utility Model Content

The multi-functional clamping structure includes a mounting groove, which is opened on the top of the clamping table. A partition plate is fixedly connected to the inner wall of the mounting groove. A disassembly and assembly structure is provided between the processing table and the clamping table. The disassembly and assembly structure includes a rectangular slot, which is opened on the top of the clamping table. A rectangular block is fixedly connected to the bottom of the clamping table. The rectangular block engages with the inner wall of the rectangular slot.

A rectangular protrusion is fixedly connected to one side of the U-shaped clamping plate and the rectangular clamping plate.

[0008] By setting a first screw and a screw hole block, the first screw can drive the screw hole block to move, which in turn can drive the U-shaped clamping plate and the rectangular clamping plate to move, and then cooperate with the rectangular protrusion to clamp and fix the workpiece.

[0009] Preferably, a fixing rod is fixedly connected to the inner wall of the mounting groove, and a sliding block is slidably connected to the outer surface of the fixing rod. The top of the sliding block is fixedly connected to the bottom of the screw hole block.

[0010] By setting a sliding block, the sliding block can slide on the outer surface of the fixed rod, thereby limiting the position of the screw hole block.

[0011] Preferably, the two sides of the U-shaped clamp are symmetrically threaded with second screws, one end of the second screw is rotatably connected to a clamping plate, the other end of the second screw is fixedly connected to an operating block, and one side of the clamping plate is fixedly connected to a limit rod, which is slidably disposed on the inner wall of the U-shaped clamp.

[0012] By setting a second screw, the second screw can drive the clamping plate to move, thereby enabling auxiliary clamping and limiting of the two opposite sides of the workpiece.

[0013] Preferably, the top of the processing table is provided with a first screw hole, and the top of the clamping table is provided with a second screw hole, and the inner walls of the first screw hole and the second screw hole are threadedly connected with threaded clamping rods.

[0016] By setting up an auxiliary operating block, the auxiliary operating block can be stored inside the storage slot after the threaded rod is engaged with the inner wall of the first and second threaded holes.

[0017] The beneficial effects of this utility model are:

[0018] By setting up a multi-functional clamping structure, the U-shaped clamping plate and the rectangular clamping plate can be driven to move under the action of the first screw and the screw hole block, thereby clamping and fixing the workpiece. The first rectangular protrusion and the second rectangular protrusion can increase the clamping friction of the U-shaped clamping plate and the rectangular clamping plate. At the same time, under the action of the second screw, the clamping plate can be driven to move, so that the clamping plate can clamp and fix the other two opposite sides of the workpiece, making the overall clamping more stable.

[0019] By setting up a disassembly and assembly structure, the clamping table and the processing table can be clamped and fixed under the action of the rectangular clamping block and the rectangular clamping slot. At this time, the rectangular clamping block and the rectangular clamping slot can be fixed in conjunction with the threaded clamping rod, the first screw hole and the second screw hole, so that the operating auxiliary block can be stored in the inner wall of the storage slot.

[0032] Reference Figure 2-3 A rotating block 33 is rotatably connected to the inner wall of the partition plate 32. Two first screws 34 are symmetrically fixed to both ends of the rotating block 33. One end of the first screw 34 passes through one side of the clamping table 2. An operating round block 315 is fixedly connected to one end of the first screw 34. The threads of the two first screws 34 are opposite in direction. A screw hole block 35 is threadedly connected to the outer surface of the first screw 34. The opposite threads of the first screws 34 allow the screw hole blocks 35 to move towards or away from each other. A U-shaped clamping plate 36 is fixedly connected to the top of one screw hole block 35, and a rectangular clamping plate 37 is fixedly connected to the top of the other screw hole block 35. The rectangular clamping plate 37 can cooperate with the U-shaped clamping plate 36 to clamp and fix. A rectangular protrusion 38 is fixedly connected to one side of the U-shaped clamping plate 36 and the rectangular clamping plate 37. The rectangular protrusion 38 can increase the friction between the U-shaped clamping plate 36 and the rectangular clamping plate 37, thereby improving the clamping stability.

[0033] Reference Figure 2 and Figure 3A fixing rod 313 is fixedly connected to the inner wall of the mounting groove 31. The fixing rod 313 passes through the partition plate 32. A sliding block 314 is slidably connected to the outer surface of the fixing rod 313. The sliding block 314 can slide on the outer surface of the fixing rod 313, thereby limiting the screw hole block 35. The top of the sliding block 314 is fixedly connected to the bottom of the screw hole block 35.

[0034] Reference Figure 2 and Figure 3 The U-shaped clamping plate 36 has symmetrical threaded connections to the two sides of the second screw 39. One end of the second screw 39 is rotatably connected to the clamping plate 311. The second screw 39 can drive the clamping plate 311 to move. The two second screws 39 on both sides can be adjusted independently, so as to adapt and clamp the workpiece. The other end of the second screw 39 is fixedly connected to the operating block 310. One side of the clamping plate 311 is fixedly connected to the limit rod 312. The limit rod 312 can limit the clamping plate 311. The limit rod 312 is slidably set on the inner wall of the U-shaped clamping plate 36.

[0035] Reference Figures 2-4 The top of the processing table 1 is provided with four first screw holes 43. The top of the clamping table 2 is provided with four second screw holes 44. After the rectangular clamping block 42 is inserted into the inner wall of the rectangular clamping groove 41, the first screw holes 43 and the second screw holes 44 are automatically aligned. The inner walls of the first screw holes 43 and the second screw holes 44 are threadedly connected with threaded clamping rods 45, which can fix the first screw holes 43 and the second screw holes 44.

[0037] Working principle:

[0038] The worker places the workpiece on the clamping table 2. Then, the first screw 34 is rotated, which causes the screw hole block 35 to move. This causes the sliding block 314 to slide on the outer surface of the fixed rod 313, which in turn causes the U-shaped clamping plate 36 and the rectangular clamping plate 37 to move, thereby clamping and fixing the workpiece. Then, the second screw 39 is rotated, which causes the clamping plate 311 to clamp the workpiece, making the clamping more stable. When the clamping table 2 needs to be disassembled for maintenance, the threaded clamping rod 45 is separated from the first screw hole 43 and the second screw hole 44, and the rectangular clamping block 42 is separated from the rectangular clamping groove 41, thereby allowing the clamping table 2 to be disassembled for maintenance.
