Description

Technical Field

[0001] This utility model relates to a stripping mechanism, and more specifically, to a stripping mechanism for transformer production. Background Technology

[0002] In the automatic lead shearing process of transformers, to ensure that the lead position does not shift, the transformer is typically moved to the processing station by a horizontal transfer assembly along a conveyor track. Commonly used horizontal transfer assemblies include a horizontally moving suspension and a plug that mates with the transformer's through-hole. To facilitate the plug's disengagement from the through-hole, the plug's size is usually slightly smaller than the through-hole. This structure causes a slight shift in the transformer during transfer, making alignment with the lead shearing equipment difficult. Conversely, when the plug's size is the same as the through-hole, it is difficult for the plug to detach directly from the through-hole after transfer. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the prior art by providing a simple and convenient unloading mechanism for transformer production.

[0004] The technical solution of this utility model is implemented as follows: A stripping mechanism for transformer production includes a conveying track for transporting transformers, a lifting platform on one side of the conveying track, a horizontal feeding component on the lifting platform, and a positioning block adapted to the through hole of the transformer frame on the horizontal feeding component; a stripping gantry is provided on the conveying track at the transformer processing station, and a stripping slot adapted to the positioning block is provided on the end of the stripping gantry near the material inlet direction; when the lifting platform is raised, the transformer is blocked by the stripping gantry and disengages from the positioning block.

[0005] In the above-mentioned transformer production unloading mechanism, the horizontal feeding assembly includes a horizontal guide rail set on a lifting platform, a sliding suspension on the horizontal guide rail, a horizontal cylinder cooperating with the sliding suspension at one end of the horizontal guide rail, and a positioning block set at the free end of the sliding suspension.

[0006] In the above-mentioned unloading mechanism for transformer production, the sliding suspension includes several sliding seats, and each sliding seat is provided with a mounting arm on the side near the conveying track. The positioning block is provided at the end of the mounting arm. The piston rod of the horizontal cylinder is connected to the farthest sliding seat, and a linkage component is provided between two adjacent sliding seats.

[0007] In the above-mentioned unloading mechanism for transformer production, the linkage component includes a through hole on a sliding seat on the side away from the horizontal cylinder, a linkage rod that cooperates with the through hole on a sliding seat on the side close to the horizontal cylinder, and a limiting nut at the front end of the linkage rod.

[0008] When the sliding seat located on the side away from the horizontal cylinder advances to the front end face and engages with the limit nut, it drags the next sliding seat forward through the linkage rod.

[0009] Each sliding seat is equipped with a limiting post. In the initial state, the limiting post on the sliding seat is in contact with the adjacent sliding seat, and the distance between two adjacent positioning blocks is equal to the distance between two adjacent through holes of the transformer to be transported.

[0010] In the above-mentioned unloading mechanism for transformer production, the positioning block includes a mounting head detachably mounted on the horizontal feeding assembly, a positioning head adapted to the transformer through hole at the bottom of the mounting head, and an elastic gap on the positioning head; the end of the positioning head is chamfered and formed with an inlet portion.

[0011] With the above-mentioned structure, the transformer is moved to the processing station by the positioning block for processing. Then, the lifting platform rises and the transformer is separated from the positioning block by the unloading gantry and left on the conveying track. It is pushed out during the next loading, which can quickly complete the unloading. No additional drive device is required, and the structure is simple. Attached Figure Description

[0018] See Figure 1-4As shown, this utility model discloses a stripping mechanism for transformer production, comprising a conveying track 1 for transporting transformers, a lifting platform 2 on one side of the conveying track 1, a horizontal feeding assembly 3 on the lifting platform 2, and a positioning block 4 adapted to the through hole of the transformer frame on the horizontal feeding assembly 3; a stripping gantry 5 is provided on the conveying track 1 at the transformer processing station, and a stripping slot 6 adapted to the positioning block 4 is provided on the end of the stripping gantry 5 near the material inlet direction; when the lifting platform 2 is raised, the transformer is blocked by the stripping gantry 5 and disengaged from the positioning block 4. After the transformer is moved to the processing station for processing by the positioning block, the lifting platform is raised and the stripping gantry separates the transformer from the positioning block and leaves it on the conveying track, where it is pushed out during the next feeding. This allows for rapid stripping without the need for an additional drive device, resulting in a simple structure.

[0019] The height of the gantry is 0.5-1.5mm greater than the height of the transformer. This ensures that the transformer can be smoothly transported under the gantry, avoids friction between the upper part of the transformer and the gantry, and prevents the transformer from falling off the conveying track and affecting subsequent conveying when the lifting platform raises the positioning block for unloading.

[0020] In this embodiment, the horizontal feeding assembly 3 includes a horizontal guide rail 3a mounted on the lifting platform 2, a sliding suspension 3b mounted on the horizontal guide rail 3a, and a horizontal cylinder 3c cooperating with the sliding suspension 3b at one end of the horizontal guide rail 3a. The positioning block 4 is located at the free end of the sliding suspension 3b. Using a cylinder for driving achieves a faster reciprocating conveying effect, improving feeding efficiency.

[0021] In this embodiment, preferably, the sliding suspension 3b includes several sliding seats 3d, and each sliding seat 3d is provided with a mounting arm 3e on the side near the material conveying track 1. The positioning block 4 is disposed at the end of the mounting arm 3e. The piston rod of the horizontal cylinder 3c is connected to the farthest sliding seat 3d, and a linkage assembly 7 is provided between two adjacent sliding seats 3d. According to the processing needs, multiple sliding seats are set to simultaneously transfer and feed multiple transformers, improving the feeding efficiency. The linkage assembly drives multiple sliding seats to move synchronously and enables the positioning block on each sliding seat to accurately engage with the transformer to be sheared.

[0022] More preferably, the linkage assembly 7 includes a through hole 7a on a sliding seat 3d on the side away from the horizontal cylinder 3c, and a linkage rod 7b on the sliding seat 3d on the side closer to the horizontal cylinder 3c, which mates with the through hole 7a. A limiting nut 7c is provided at the front end of the linkage rod 7b. The linkage rod is detachably mounted on the sliding suspension via the nut. When there are many sliding suspensions, a clearance through hole is provided on the rear sliding suspension to prevent the nut at the mounting end of the linkage rod from colliding with the rear sliding suspension when returning to the initial state.

[0023] When the sliding seat 3d located on the side away from the horizontal cylinder 3c advances to the front end face and engages with the limit nut 7c, it drags the next sliding seat 3d forward through the linkage rod 7b.

[0024] Each sliding seat 3d is equipped with a limiting post 7d. In the initial state, the limiting post 7d on the sliding seat 3d is in contact with the adjacent sliding seat 3d, and the distance between two adjacent positioning blocks 4 is equal to the distance between two adjacent through holes of the transformer to be transported. The limiting posts restrict and position the initial position of the sliding seat, ensuring that the positioning blocks correspond one-to-one with the through holes of the transformer to be transported, thus ensuring the transport process.

[0025] In this embodiment, the positioning block 4 includes a mounting head 4a detachably mounted on the horizontal feeding assembly 3. A positioning head 4b, adapted to the transformer through-hole, is located at the bottom of the mounting head 4a. An elastic gap 4c is provided on the positioning head 4b. An inlet portion 4d is chamfered at the end of the positioning head 4b. With this structure, the elastic gap provides a certain tensioning capacity to the positioning head, facilitating insertion into the transformer through-hole and ensuring a tight fit. Furthermore, the mounting head allows for easy assembly and disassembly of the positioning head, enabling the replacement of different positioning heads according to the size of the transformer to be processed. This allows for the processing of transformers of different sizes on the same production line, reducing workshop costs.

[0026] During operation, when the transformer to be processed moves along the conveyor track to below the positioning block, the lifting platform descends, causing the positioning block to insert into the through hole of the transformer frame. The piston rod of the horizontal cylinder extends and pushes the sliding seat, moving the transformer to the processing station below the unloading gantry. After the transformer is processed, the lifting platform rises, and the transformer is blocked by the unloading gantry, disengaging from the positioning block. The positioning block returns to its initial position for the next conveying cycle.

[0027] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
