Description

Technical Field

[0001] This invention belongs to the field of transformer manufacturing technology, and specifically relates to a clamping component. Background Technology

[0002] Clamping assemblies are devices used to fix and support workpieces, widely used in manufacturing, machining, electronics assembly, construction, and many other fields. Their main function is to ensure the stability of workpieces during processing, assembly, or testing, preventing movement, deformation, or damage. The design and performance of clamping assemblies directly affect production efficiency, product quality, and safety. Core clamping assemblies used in transformer manufacturing are devices used to fix and support the core during transformer manufacturing. The core is the core component of the transformer, responsible for conducting the magnetic field, and the clamping assembly ensures the core remains stable during manufacturing and assembly, preventing loosening and thus guaranteeing the stability of the transformer during assembly.

[0003] Existing transformer core clamping assemblies clamp the transformer core by driving four clamping plates that move towards each other simultaneously, securing them for subsequent coil installation. While this single drive unit saves drive resources and power, allowing for comprehensive clamping of the transformer core, the fixed spacing between the four plates restricts its application to cores with specific aspect ratios. This fails to meet the needs of producing transformers of varying sizes, resulting in low flexibility and limited usability. Furthermore, when clamping and securing transformer cores of different sizes is required, extension plates must be added to the inner surfaces of the clamping plates. This process demands significant manpower and tools, increasing workload and reducing assembly efficiency. Summary of the Invention

[0004] In view of this, the present invention addresses the shortcomings of the prior art by providing a clamping assembly that can simultaneously drive four clamping plates to achieve comprehensive clamping and fixing of the transformer core. It can also freely adjust the spacing between the front and rear clamping plates and the left and right clamping plates, making it flexible for clamping and fixing transformers of different lengths and widths. This improves the versatility and adaptability of the clamping assembly, while also reducing the workload of personnel and improving the efficiency of transformer assembly.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a clamping assembly, including a support mounting frame, two frames are provided at the upper end of the support mounting frame, the frames are fixed to the support mounting frame by welding, the two frames are symmetrically positioned left and right, a mounting plate is provided between the two frames, the two frames and the mounting plate are fixed by welding, lifting frames are slidably arranged inside each of the two frames, the two lifting frames are symmetrically positioned left and right, a placement plate is provided between the upper ends of the two lifting frames, the lifting frames and the placement plate are fixed by welding, a fully adjustable clamping mechanism is provided inside the placement plate, and a height adjustment mechanism is provided inside the mounting plate. The fully adjustable clamping mechanism includes four hollow frames slidably arranged inside the placement plate, locking pins are slidably arranged in through holes opened inside the four hollow frames, pull plates are provided at the upper ends of the four locking pins, the locking pins and pull plates are fixed by welding, and clamping plates are also slidably arranged inside the four hollow frames. Each cavity frame has multiple equally spaced locking holes. Four locking pins are inserted into one of the adjacent locking holes. Each of the four cavity frames has a rotating seat at its lower end. Each of the four rotating seats has a connecting frame rotatably mounted inside it. A connecting plate is set between the two lifting frames. A lead screw is rotatably mounted between the connecting plate and the placement plate. A moving disc is threaded onto the outer surface of the lead screw. Four equally spaced rotating frames are set on the outer arc surface of the moving disc. The moving disc and the rotating frames are fixed by welding. The lower ends of the four connecting frames are rotatably connected to the adjacent rotating frames. An elastic drive unit is set between the pull plate and the cavity frame. An electric drive unit is set at the lower end of the connecting plate to drive the lead screw. The elastic drive unit includes multiple springs set between the pull plate and the cavity frame. The multiple springs are respectively sleeved on the outer arc surface of the corresponding locking pin. The electric drive unit includes a motor set at the lower end of the connecting plate. The output shaft of the motor is connected to the lower end of the lead screw through a coupling.

[0006] As a further improvement of the present invention, the interior of the support mounting frame is provided with multiple mounting holes, which are located at the four corners of the support mounting frame.

[0007] As a further improvement of the present invention, the height adjustment mechanism includes two sliding blocks slidably disposed inside the mounting plate, the two sliding blocks being oriented left and right, two rotating frames II being disposed at the upper end of each of the two sliding blocks, and connecting frames II being rotatably disposed inside each of the four rotating frames II, and multiple rotating seats II being disposed on the front and rear sides of the connecting plate, the upper ends of the multiple connecting frames II being rotatably connected to the interior of the adjacent rotating seats II respectively, and an electric drive unit II for driving the two sliding blocks to move is disposed at the lower end of the mounting plate, the electric drive unit II including a hydraulic push rod disposed at the lower end of the mounting plate, the two hydraulic push rods being oriented left and right, and the telescopic ends of the two hydraulic push rods being connected to the opposite inner ends of the two sliding blocks respectively.

[0008] As a further improvement of the present invention, a control panel is provided at the upper end of the support mounting frame, and the motor and hydraulic push rod are electrically connected to the control panel.

[0009] As a further improvement of the present invention, buffer pads are bonded to the inner side of the clamping plate.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: Firstly, the transformer core to be clamped and assembled is hoisted to the upper end of the placement plate using hoisting equipment and positioned between four clamping plates. Then, the motor is turned on via the control panel, and the output shaft drives the lead screw to rotate, causing the rotating frame on the threaded moving plate to move downward under the constraint of the cavity frame inside the placement plate. This causes the connecting frame inside to rotate and retract, simultaneously driving the clamping plates inside the four cavity frames on the rotating seat to move closer together, thus clamping the transformer core on the front, back, left, and right sides. The transformer core can be quickly clamped and fixed by driving the four clamping plates to move closer together using a single motor.

[0011] Secondly, the buffer pads on the inner sides of the four clamping plates enable flexible contact with the transformer core, avoiding direct hard contact between the clamping plates and the transformer core that could cause damage, thus ensuring the quality of the transformer core.

[0012] Thirdly, by pulling the pull plate, the locking pin moves away from the locking hole in the clamping plate. At this time, the spring is stretched, which can pull the clamping plate to a suitable position so that one of the locking holes corresponds to the position of the locking pin. Then, the pull plate is released, and the spring quickly rebounds, causing the locking pin to insert into the locking hole, thus locking and fixing the clamping plate. Personnel can adjust the remaining clamping plates in the same way to ensure that the four clamping plates can fully clamp and fix the transformer core after they are close together. Then, the motor is turned on by controlling the control panel to bring the four clamping plates closer together to achieve all-round clamping of the new transformer core. The four clamping plates can be driven at the same time to achieve full clamping and fixing of the transformer core. At the same time, the distance between the front and rear clamping plates and the left and right clamping plates can be freely adjusted. It can be flexibly applied to clamping and fixing transformers of different lengths and widths, improving the versatility and adaptability of the clamping components, reducing the workload of personnel, and improving the efficiency of transformer assembly.

[0013] Fourth, the hydraulic push rod is operated by controlling the control panel, which causes the telescopic end to move the rotating frame two on both sides of the sliding block away from or towards each other, causing the connecting frame two inside to rotate and expand or contract, thereby driving the connecting plate on the rotating seat two to move up or down. And through the lifting frame, the placement plate moves up or down under the restriction and guidance inside the frame, thereby realizing the adjustment of the height of the clamping component for the transformer core. It can adapt to transformer cores of different heights without replacing the entire clamping component or making complex adjustments, thus improving the versatility and adaptability of the clamping component.

[0014] Fifth, the support mounting frame can provide stable support for the clamping components. The mounting holes inside allow personnel to insert fixing bolts to fix it in the appropriate position, preventing the clamping components from shifting when clamping the transformer core, thus making the clamped transformer coil more stable.

Detailed Implementation

[0018] To better understand the present invention, the following embodiments further illustrate the content of the invention, but the scope of protection of the present invention is not limited to the following embodiments. Numerous specific details are set forth in the following description to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details.

[0019] like Figure 1 , 2 As shown in Figure 5, a clamping assembly includes a support mounting frame 101. Two frames 102 are disposed at the upper end of the support mounting frame 101, with the left and right positions of the two frames 102 corresponding. A mounting plate 106 is disposed between the two frames 102. Lifting frames 103 are slidably disposed inside each of the two frames 102. A placement plate 104 is disposed between the upper ends of the two lifting frames 103. An omnidirectionally adjustable clamping mechanism is disposed inside the placement plate 104. A height adjustment mechanism is disposed inside the mounting plate 106, and the height adjustment mechanism includes two sliding blocks 305 slidably disposed inside the mounting plate 106. Two rotating frames 301 are provided at the upper ends of the two sliding blocks 305. Connecting frames 304 are rotatably provided inside the four rotating frames 301. Multiple rotating seats 303 are provided on the front and rear sides of the connecting plate 212. The upper ends of the multiple connecting frames 304 are rotatably connected to the interior of the adjacent rotating seats 303. An electric drive unit 2 for driving the two sliding blocks 305 to move is provided at the lower end of the mounting plate 106. The electric drive unit 2 includes a hydraulic push rod 302 provided at the lower end of the mounting plate 106. The telescopic ends of the two hydraulic push rods 302 are respectively connected to the opposite inner ends of the two sliding blocks 305.

[0020] like Figure 1 , 2As shown in Figures 3, 4, and 5, the omnidirectional adjustable clamping mechanism includes four hollow frames 201 slidably disposed inside the placement plate 104. Locking pins 205 are slidably disposed within through holes opened inside each of the four hollow frames 201. Pull plates 207 are provided at the upper ends of each of the four locking pins 205. Clamping plates 202 are also slidably disposed inside each of the four hollow frames 201. Multiple locking holes 208 arranged at equal intervals are opened inside each of the four clamping plates 202. Each of the four locking pins 205 is inserted into one of the adjacent locking holes 208. A rotating seat 203 is provided at the lower end of each of the four hollow frames 201. A connecting frame 204 is rotatably disposed inside each of the four rotating seats 203. A connecting plate 212 is disposed between the two lifting frames 103. A screw is rotatably disposed between the connecting plate 212 and the placement plate 104. A movable disc 210 is threaded onto the outer surface of the rod 211 and the lead screw 211. Four equally spaced rotating frames 213 are provided on the outer arc surface of the movable disc 210. The lower ends of the four connecting frames are rotatably connected to the adjacent rotating frames 213. An elastic drive unit is provided between the pull plate 207 and the cavity frame 201. An electric drive unit 1 for driving the lead screw 211 to rotate is provided at the lower end of the connecting plate 212. The elastic drive unit includes multiple springs 206 provided between the pull plate 207 and the cavity frame 201. The multiple springs 206 are respectively sleeved on the outer arc surface of the corresponding locking pins 205. The electric drive unit 1 includes a motor 209 provided at the lower end of the connecting plate 212. The output shaft of the motor 209 is connected to the lower end of the lead screw 211 through a coupling. Buffer pads 214 are glued to the inner side of the clamping plate 202.

[0021] like Figure 1 As shown, a control panel 401 is provided at the upper end of the support mounting frame 101, and the motor 209 and hydraulic push rod 302 are electrically connected to the control panel 401. The transformer core to be clamped and assembled is hoisted to the upper end of the placement plate 104 by a hoisting device and positioned between four clamping plates 202. Then, the motor 209 is turned on by the control panel 401. The output shaft drives the lead screw 211 to rotate, causing the rotating frame 213 on the threaded moving disk 210 to move downward under the constraint of the cavity frame 201 inside the placement plate 104. This causes the connecting frame 204 inside to rotate and retract, while driving the clamping plates 202 inside the four cavity frames 201 on the rotating seat 203 to move closer together to clamp the front, back, left and right sides of the transformer core. The buffer pads 214 on the inner side of the four clamping plates 202 can achieve flexible contact with the transformer core, avoiding direct hard contact between the clamping plates 202 and the transformer core, which could cause damage.

[0022] When it is necessary to clamp transformer cores of different sizes, by pulling the pull plate 207, the locking pin 205 is moved away from the locking hole 208 on the clamping plate 202. At this time, the spring 206 is in a stretched state, which can pull the clamping plate 202 to a suitable position and make one of the locking holes 208 correspond to the position of the locking pin 205. Then, the pull plate 207 is released, and the spring 206 quickly rebounds, causing the locking pin 205 to be inserted into the locking hole 208, thereby locking and fixing the clamping plate 202. Personnel can adjust the other clamping plates 202 in the same way to ensure that the four clamping plates 202 can fully clamp and fix the transformer core after they are brought closer together. Then, the motor 209 is turned on by the control panel 401 to bring the four clamping plates 202 closer together to achieve all-round clamping of the new transformer core.

[0023] When it is necessary to adjust the clamping height of the transformer core, the hydraulic push rod 302 is opened by the control panel 401, which causes the telescopic end to drive the rotating frame 301 on both sides of the sliding block 305 to move away from or towards each other, causing the connecting frame 304 inside to rotate and expand or contract, thereby driving the connecting plate 212 on the rotating seat 303 to move up or down, and through the lifting frame 103, the placement plate 104 moves up or down under the restriction and guidance inside the frame 102, thereby realizing the adjustment of the clamping height of the transformer core to meet the different assembly height requirements of personnel.

[0024] According to another embodiment of the invention, such as Figure 1 As shown, the support mounting frame 101 has multiple mounting holes 105 inside. The multiple mounting holes 105 are located at the four corners of the support mounting frame 101. The support mounting frame 101 can provide stable support for the clamping component. The mounting holes 105 inside allow personnel to insert fixing bolts to fix it in the appropriate position, preventing the clamping component from shifting when clamping the transformer core.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention, as long as they do not depart from the spirit and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
