[0035] The following is combined with Figures 1 to 3 The technical solution of the utility model is further illustrated through specific implementation methods.

[0036] A clamping and flipping unit for a semi-finished transformer includes a flipping drive assembly, a support frame, a lower clamping assembly 2, and an upper clamping assembly 3;

[0037] The support frame includes a horizontal plate 11 and a vertical plate 12, wherein the vertical plate 12 is perpendicular to the horizontal plate 11 and is located at one end of the horizontal plate 11;

[0038] The lower clamping assembly 2 is installed at one end of the horizontal plate 11 away from the vertical plate 12, and the lower clamping assembly 2 is used to clamp and fix the lower part of the workpiece placed on the horizontal plate 11;

[0039] The upper clamping assembly 3 is mounted on the top of the vertical plate 12, and is used to press downward against the top of the workpiece so that the workpiece is fixed to the support frame at upper and lower limits;

[0040] The support frame is installed on the driving end of the flip driving assembly, and the flip driving assembly is used to drive the support frame to flip up and down.

[0041] The present invention provides a clamping and flipping unit for a transformer semi-finished product, which is used to clamp and fix the semi-finished product (hereinafter referred to as "workpiece") obtained by assembly and manufacturing during the production and processing of the transformer, and flip the workpiece to assemble and inspect other components. The present invention achieves multi-point fixation of the workpiece by designing a lower clamping component 2 and an upper clamping component 3 to clamp the workpiece from the bottom and top of the workpiece respectively. Specifically, during the production process, after the workpiece is placed on the horizontal plate 11, the lower clamping component 2 clamps and fixes the lower part of the workpiece; thereafter, the upper clamping component 3 acts on the top of the workpiece and applies a downward force against the top of the workpiece, so that the upper and lower limit clamps of the workpiece are clamped between the upper clamping component 3 and the horizontal plate 11; after the workpiece is clamped firmly, the flipping drive component drives the support frame to flip up and down, and the subsequent assembly or inspection of the workpiece can be carried out. This method of clamping the upper and lower parts of the workpiece separately, on the one hand, effectively disperses the gravity of the workpiece, enhances the stability of the clamping, and reduces the risk of falling off due to the large mass of the workpiece during the flipping process; on the other hand, the clamping component does not act on the middle of the workpiece, avoiding damage to the workpiece during the clamping and flipping process. At the same time, the clamping component avoids the accessories and assembly stations in the middle of the workpiece, which is more convenient for subsequent processing or observation and inspection of the workpiece.

[0042] Furthermore, the lower clamping assembly 2 includes a first clamping driver 21, two clamping plates 22 and a bottom plate 23;

[0043] The first clamping driver 21 and the bottom plate 23 are installed at one end of the horizontal plate 11 away from the vertical plate 12, and the bottom plate 23 is arranged horizontally and is used to hold the workpiece;

[0044] The two clamping plates 22 are parallel to each other and arranged opposite to each other. The two clamping plates 22 are respectively extended upward to form a clamping space, which is used to accommodate the lower part of the workpiece of the horizontal plate 11. The first clamping driver 21 is used to drive the two clamping plates 22 to move toward or away from each other.

[0045] The two clamping plates 22 are arranged parallel to each other and face each other, forming a stable clamping structure. During the clamping process, the two clamping plates can simultaneously and evenly apply clamping force, avoiding the problems of workpiece tilting or slipping that may occur with single-point clamping, further improving the stability of the clamping. By introducing a first clamping driver 21 to drive the two clamping plates 22 toward or away from each other, a more precise and controllable clamping of the lower portion of the transformer semi-finished product is achieved. This design of dynamically adjusting the clamping force can flexibly respond to the quality and shape of different semi-finished products, ensuring that the clamping is both stable and does not cause damage to the semi-finished product.

[0046] Furthermore, the lower clamping assembly 2 also includes a mounting plate 241 and two limit blocks 242. The mounting plate 241 is detachably connected to the clamping plate 22. The mounting plate 241 and the clamping plate 22 are parallel to each other. The limit blocks 242 are perpendicular to the mounting plate 241. The two limit blocks 242 are respectively located at both ends of the mounting plate 241 to form a C-shaped limit piece. The openings of the C-shaped limit pieces of the two clamping plates 22 are arranged relative to each other.

[0047] The mounting plate 241 and the limit blocks 242 at each end form a C-shaped limiter. The C-shaped limiter is removably mounted on the clamping plate 22. The openings of the C-shaped limiters on the two clamping plates 22 are positioned relative to each other. When the first clamping driver 21 drives the two clamping plates 22 closer together, the C-shaped limiters approach the lower portion of the workpiece and form a more precise clamping space for it. The limit blocks 242 on the two clamping plates 22 extend toward each other, forming a square clamping space between the two clamping plates 22 and the four limit blocks 242, which can surround the workpiece on all sides during the clamping process.

[0048] By adding a C-shaped stopper and removably attaching it to the clamping plate 22, the workpiece can be effectively prevented from lateral sliding or shifting during the clamping process. The design of the stopper 242 restricts the horizontal movement of the workpiece, ensuring safety and stability during the clamping process. This prevents accidents caused by inaccurate workpiece positioning during the flipping process. This design improves clamping accuracy and reliability.

[0049] Preferably, the stopper 242 is made of a soft material, such as rubber or plastic, to reduce friction and damage to the workpiece surface. During the clamping process, the stopper 242 can gently contact the workpiece surface to prevent problems such as scratches or indentations caused by excessive clamping force.

[0050] Furthermore, the upper clamping assembly 3 is mounted on the top of the vertical plate 12 via a second horizontal plate 13;

[0051] The upper clamping assembly 3 includes a second clamping driver 31 and an upper clamping portion. The second clamping driver 31 is installed on the second horizontal plate 13. The second clamping driver 31 is used to drive the upper clamping portion to approach and press downwardly toward or away from the top of the workpiece.

[0052] By introducing a second clamping driver 31 to drive the upper clamping portion toward or away from the top of the workpiece, the clamping force and position of the upper clamping portion can be precisely adjusted as needed. This flexibility enables the clamping and flipping unit to adapt to semi-finished transformers of different specifications, shapes, and weights, thereby improving the versatility and adaptability of the equipment. Specifically, since the workpiece is disposed on the horizontal plate 11, when the second clamping driver 31 drives the upper clamping portion toward and presses downward against the top of the workpiece, the workpiece is fixed between the horizontal plate 11 and the upper clamping portion by upper and lower limits. This clamping method not only ensures the stability of the workpiece during the flipping process, but also reduces the pressure concentration on the workpiece surface, thereby avoiding damage caused by excessive clamping force.

[0053] Furthermore, the upper clamping portion includes a clamping arm 321, a support 322, a rack 323 and a gear 324;

[0054] The second clamping driver 31 is provided on the second horizontal plate 13, and the rack 323 is installed at the driving end of the second clamping driver 31. The rack 323 extends in the front-to-back direction, and the second clamping driver 31 drives the rack 323 to move forward and backward.

[0055] The support 322 is vertically installed on the top surface of the second horizontal plate 13 , the gear 324 is installed on one end of the clamping arm 321 , one end of the clamping arm 321 having the gear 324 is hinged to the support 322 , and the gear 324 is meshed with the rack 323 .

[0056] The upper clamping part is designed to include a clamping arm 321, a support 322, a rack 323 and a gear 324; the support 322 is vertically installed on the top surface of the second horizontal plate 13, providing a stable support for the clamping arm 321, and the clamping arm 321 is hinged to the support 322, so that the clamping arm 321 can swing flexibly during the clamping process; the second clamping driver 31 is used to drive the rack 323 to move back and forth, and then the clamping arm 321 is driven to open and close through the meshing relationship between the gear 324 and the rack 323, thereby achieving precise control of the clamping arm 321 approaching or moving away from the top of the workpiece.

[0057] The transmission mechanism of the clamping and flipping unit is simplified by the use of a rack 323 and gear 324. Since the opening and closing movement of the clamping arm 321 is driven by the second clamping actuator 31, the operator can clamp and release the top of the workpiece simply by controlling the actuator, eliminating the need to manually adjust the clamping position or force, thereby improving operational convenience and efficiency.

[0058] Furthermore, a slide rail 331 is provided on the top surface of the second horizontal plate 13, and the slide rail 331 extends in the front-to-back direction;

[0059] The driving end of the second clamping driver 31 is provided with a slider 332 . The slider 332 is slidably connected with the slide rail, and the rack 323 is mounted on the slider 332 .

[0060] By providing a slide rail 331 on the top surface of the second horizontal plate 13 and connecting the driving end of the second clamping driver 31 to the slider 332, the rack 323 can slide smoothly along the slide rail 331 during movement. This design effectively reduces vibration and deviation caused by movement and improves the clamping stability of the upper clamping assembly 3.

[0061] Furthermore, the top surface of the second horizontal plate 13 is further provided with a front limiting portion 41 and a rear limiting portion 42, and the front limiting portion 41 and the rear limiting portion 42 are arranged to cooperate with each other in the front-to-back direction;

[0062] A limiting post 43 is provided on one side of the slider 332 , and the limiting post 43 protrudes perpendicularly from the line connecting the front limiting portion 41 and the rear limiting portion 42 .

[0063] By providing a front stopper 41 and a rear stopper 42 on the top surface of the second horizontal plate 13, which cooperate with the stopper post 43, the upper clamping assembly 3 is provided with additional safety protection, preventing the slider 332 from moving beyond a predetermined range. By limiting the range of movement of the slider 332, safety issues such as component damage or loss of structural components caused by excessive movement are avoided. This design helps to extend the service life of the equipment and reduce maintenance costs.

[0064] Furthermore, a friction roller 325 is rotatably provided at the other end of the clamping arm 321 .

[0065] When the upper clamping assembly 3 of the present invention acts on the top of the workpiece to perform clamping work, the friction roller 325 plays a role of flexible contact, reducing wear on the workpiece and effectively extending the service life of the clamping arm 321.

[0066] The technical principles of the present invention have been described above with reference to specific embodiments.
