Description
Technical Field
[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a clamping device. Background Technology
[0002] In the process of mechanical design and manufacturing, workpieces are often welded. When welding workpieces, clamping mechanisms are used to fix the position of the workpieces to ensure that the workpieces are more stable during welding. However, existing clamping devices cannot fix workpieces from multiple positions, resulting in unstable workpiece clamping. The position is prone to shifting during the welding process. Moreover, after welding, the surface temperature of the workpiece is high, and the natural cooling of the workpiece takes a long time, resulting in low work efficiency.
[0003] To address the aforementioned technical problems, a patent document with publication number (CN218695512U) discloses a clamping mechanism for mechanical design and manufacturing, comprising components such as a fixed base, a stepper motor, a bidirectional screw, a guide rod, a moving block, a clamping seat, and a clamping mechanism. The fixed base has a stepper motor on its right outer wall, with the output end of the stepper motor connected to the bidirectional screw. The bottom end of the bidirectional screw is movably connected to the inner wall of the fixed base via a bearing. A guide rod is located at the bottom of the inner cavity of the fixed base, and moving blocks are connected to both sides of the guide rod and the bidirectional screw. A slot matching the moving block is formed at the bottom of the fixed base, and a clamping seat is connected to the bottom of the moving block. A clamping mechanism is provided on the clamping seat. A water tank is located in the center of the upper surface of the fixed base, and the water tank is connected to a cooling mechanism, which includes a nozzle. This invention fixes the workpiece position from multiple directions, improving the stability of the workpiece during welding, increasing the cooling efficiency of the workpiece, and improving the production efficiency of the workpiece.
[0004] However, in the aforementioned existing technologies, when welding multiple sides of a workpiece is required, the workpiece needs to be removed, flipped, and then re-clamped and fixed, which is very time-consuming and labor-intensive. Utility Model Content

The rotating assembly includes a rotating disk 117 and a gripping rod 118. The clamping device also includes a water tank 119, a water pipe 120, a spray pipe 121, and a water pump 122. The aforementioned solution solves the problem in the prior art that when welding multiple sides of a workpiece is required, the workpiece needs to be removed, flipped, and then re-clamped and fixed, which is very time-consuming and labor-intensive.
[0021] In this specific embodiment, the mounting frame 102 is fixedly connected to the lower surface of the base plate 101. The bidirectional threaded rod 103 passes through two movable plates 104 and is threadedly engaged with both movable plates 104. Both ends of the bidirectional threaded rod 103 are rotatably connected to the mounting frame 102. Two sets of clamping assemblies are fixedly connected to the two movable plates 104. Two mounting plates 105 are symmetrically arranged on the lower surface of the base plate 101. The lead screw 106 passes through the frame 108 and is threadedly engaged with the frame 108. Both ends of the lead screw 106 are rotatably connected to the two mounting plates 105. A rotating assembly is located at one end of the lead screw 106. One end of the round rod 109 is fixedly connected to one set of clamping assemblies. The other end of 09 passes through the frame 108, and the guide rod 107 passes through the frame 108 and is slidably connected to the frame 108. The two ends of the guide rod 107 are respectively fixedly connected to the two mounting plates 105. In actual use, the motor 123 is started, and the motor 123 drives the bidirectional threaded rod 103 to rotate, so that the two moving plates 104 move relative to each other. The two moving plates 104 respectively drive the two sets of clamping components to move relative to each other, thereby clamping the workpiece and then welding the workpiece. When flipping welding is required, the rotating component drives the lead screw 106 to rotate, so that the frame 108 moves. The frame 108 abuts against the round rod 109 and moves. The round rod 109 drives one of the clamping components to rotate, thereby flipping the workpiece.
[0022] The support plate 110 is fixedly connected to the corresponding movable plate 104. The disc 111 passes through the support plate 110 and is rotatably connected to the support plate 110. Two limiting rings 112 are respectively sleeved on the outer side of the disc 111. Multiple sets of abutting members are disposed on one side of the disc 111. In actual use, the movable plate 104 drives the support plate 110 to move, and the support plate 110 drives the disc 111 to move, thereby clamping both ends of the workpiece. Then, the outer side of the workpiece is abutted by the multiple sets of abutting members.
[0023] Secondly, the fixing plate 113 is fixedly connected to the disc 111 and located on one side of the disc 111. The first threaded rod 114 passes through the fixing plate 113 and is threadedly engaged with the fixing plate 113. One end of the first threaded rod 114 is fixedly connected to the round button 115, and the other end of the first threaded rod 114 is rotatably connected to the abutment plate 116. In actual use, rotating the round button 115 causes the first threaded rod 114 to rotate, and the first threaded rod 114 causes the abutment plate 116 to move, thereby abutting the outer side of the workpiece.
[0024] Meanwhile, the rotating disk 117 is fixedly connected to one end of the lead screw 106, and the grip 118 is fixedly connected to one side of the rotating disk 117. In actual use, rotating the grip 118 will cause the rotating disk 117 to rotate, and the rotating disk 117 will cause the lead screw 106 to rotate.
[0025] In addition, the water tank 119 is disposed on the upper surface of the base plate 101, one end of the water pipe 120 is fixedly connected to the water tank 119, and the other end of the water pipe 120 is fixedly connected to the spray pipe 121. The water pump 122 is disposed at one end of the water pipe 120. In actual use, the water pump 122 is started, so that the water in the water tank 119 flows through the water pipe 120 to the spray pipe 121, and then is sprayed onto the workpiece through the spray pipe 121, thereby cooling the workpiece.
[0026] In the specific use of the clamping device of this embodiment, the motor 123 is started, which drives the bidirectional threaded rod 103 to rotate, causing the two moving plates 104 to move relative to each other. The two moving plates 104 respectively drive the two supporting plates 110 to move relative to each other. The supporting plates 110 drive the disc 111 to move, thereby clamping both ends of the workpiece. Then, the knob 115 is rotated, which drives the first threaded rod 114 to rotate. The first threaded rod 114 drives the abutment plate 116 to move, thereby abutting the outer side of the workpiece. Then, the workpiece is welded. When flipping welding is required, the gripping rod 118 is rotated, and the gripping rod 11... 8 drives the rotating disk 117 to rotate, the rotating disk 117 drives the lead screw 106 to rotate, causing the frame 108 to move. The frame 108 abuts against the round rod 109 to move, and the round rod 109 drives one of the round disks 111 to rotate, thereby flipping the workpiece. After welding is completed, the water pump 122 is started, so that the water in the water tank 119 flows through the water pipe 120 to the spray pipe 121, and then sprays onto the workpiece through the spray pipe 121 to cool the workpiece. This method can effectively solve the problem in the prior art that when welding multiple sides of a workpiece is required, the workpiece needs to be removed, flipped, and then re-clamped and fixed, which is very time-consuming and labor-intensive.
