Description

Technical Field

[0001] This utility model relates to the field of transformer manufacturing technology, specifically to a magnetic shielding manufacturing tooling. Background Technology

[0002] In the assembly process of magnetic shielding, multiple silicon steel sheets are typically clamped between two fixing plates and then fastened with bolts to form an integral structure, which is finally welded to the transformer body to achieve leakage magnetic shielding. However, due to the lack of a unified positioning reference and dedicated clamping fixtures in traditional assembly methods, when the silicon steel sheets are clamped by manual positioning or clamping mechanisms in actual operation, the clamping force of the clamping mechanism is distributed outward from a single point. This results in a difference in clamping force between the silicon steel sheets far from the point of application and those at the point of application, which can easily lead to gaps or tilting in the arrangement of some silicon steel sheets.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a magnetic shielding manufacturing tooling to solve the technical problem that in the related technology, the clamping mechanism applies force from one point outward to complete the clamping. This will result in the clamping force of the silicon steel sheet far from the force application point being different from that of the silicon steel sheet at the force application point, which may easily lead to gaps or tilting in the arrangement of some silicon steel sheets.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a magnetic shielding manufacturing fixture is provided, comprising: at least two first clamping components, each first clamping component being spaced apart along a first preset direction, and at least a portion of each first clamping component being movably disposed; the moving direction of each first clamping component being perpendicular to the first preset direction; and at least two second clamping components, each second clamping component being spaced apart along the first preset direction, each second clamping component being disposed opposite to each first clamping component, and at least a portion of each second clamping component being movably disposed along the moving direction of the first clamping component.

[0006] Furthermore, the first clamping assembly has a first positioning part and a first moving part, the first moving part being movably disposed relative to the first positioning part; the second clamping assembly has a second positioning part and a second moving part, the second moving part being movably disposed relative to the second positioning part; the second moving part and the first moving part are disposed opposite to each other.

[0007] Furthermore, the first clamping assembly includes: a first positioning nut, which is spaced apart along a first preset direction; and a first positioning bolt, which extends along a second preset direction and is threadedly engaged with the first positioning nut; the second clamping assembly includes: a second positioning nut, which is spaced apart along the first preset direction; and a second positioning bolt, which extends along the extension direction of the first positioning bolt and is threadedly engaged with the second positioning nut.

[0008] Furthermore, the magnetic shielding manufacturing fixture also includes: an operating table, which is mounted on an installation reference; a first support plate, which extends along a first preset direction and is mounted on the operating table; a first clamping assembly is provided on the top of the first support plate; a second support plate, which extends along the extension direction of the first support plate and is mounted on the operating table; the second support plate is spaced apart from the first support plate, and a second clamping assembly is provided on the top of the second support plate.

[0009] Furthermore, the magnetic shielding manufacturing fixture also includes: a placement plate, the bottom of which is connected to the operating table, a first support plate being movably mounted on the placement plate in the direction of a second support plate, and a second support plate being movably mounted on the placement plate in the direction of a first support plate.

[0010] Beneficial effects:

[0011] 1. By forming distributed pressure points with at least two first clamping components and at least two second clamping components spaced apart along a first preset direction, multi-directional balanced clamping of silicon steel sheet assembly is achieved and local force deviation is eliminated.

[0012] 2. The first moving part is driven to move linearly by the threaded engagement of the first positioning bolt and the first positioning nut, and the second moving part is driven to move linearly by the threaded engagement of the second positioning bolt and the second positioning nut, thereby achieving precise and controllable adjustment of the clamping force.

[0013] 3. The movable arrangement of the first support plate and the second support plate on the placement plate forms a stepless width adjustment mechanism to accommodate silicon steel sheet assemblies of different sizes. Attached Figure Description

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] According to an embodiment of this utility model, a magnetic shielding manufacturing fixture is provided. Please refer to [link / reference]. Figure 1 The first clamping component 1 includes at least two first clamping components 1, each first clamping component 1 being spaced apart along a first preset direction, and at least a portion of each first clamping component 1 being movably disposed; the moving direction of each first clamping component 1 being perpendicular to the first preset direction; and at least two second clamping components 2, each second clamping component 2 being spaced apart along the first preset direction, each second clamping component 2 being disposed opposite to each first clamping component 1, and at least a portion of each second clamping component 2 being movably disposed along the moving direction of the first clamping component 1.

[0019] By adopting the above technical solution, at least two first clamping components 1 and at least two second clamping components 2, which are spaced apart along the first preset direction, form distributed pressure points, thereby achieving multi-directional balanced clamping of the silicon steel sheet group and eliminating local force deviation.

[0020] The first clamping components 1 and the second clamping components 2 can be arranged in a staggered manner or relative to each other, and each first clamping component 1 and each second clamping component 2 can be adjusted and moved individually.

[0021] Please refer to Figure 1 The first clamping assembly 1 has a first positioning part and a first moving part, the first moving part being movably disposed relative to the first positioning part; the second clamping assembly 2 has a second positioning part and a second moving part, the second moving part being movably disposed relative to the second positioning part; the second moving part and the first moving part are disposed opposite to each other.

[0022] By adopting the above technical solution, the independent movement of the first moving part relative to the first positioning part and the independent movement of the second moving part relative to the second positioning part provide bidirectional synchronous stroke control to ensure that the clamping surfaces are parallel and in contact.

[0023] Please refer to Figure 1The first clamping assembly includes: a first positioning nut 3, which is spaced apart along a first preset direction; a first positioning bolt 4, which extends along a second preset direction and is threadedly engaged with the first positioning nut 3; the second clamping assembly includes: a second positioning nut 5, which is spaced apart along the first preset direction; and a second positioning bolt 6, which extends along the extension direction of the first positioning bolt 4 and is threadedly engaged with the second positioning nut 5.

[0024] The first positioning nut 3 forms a first positioning part; the first positioning bolt 4 forms a first moving part; the second positioning nut 5 forms a second positioning part; and the second positioning bolt 6 forms a second moving part.

[0025] By adopting the above technical solution, the threaded engagement between the first positioning bolt 4 and the first positioning nut 3 drives the linear displacement of the first moving part, and the threaded engagement between the second positioning bolt 6 and the second positioning nut 5 drives the linear displacement of the second moving part, thereby achieving precise and controllable adjustment of the clamping force.

[0026] Please refer to Figure 1 The magnetic shielding manufacturing fixture also includes: an operating table 7, which is mounted on an installation reference; a first support plate 8, which extends along a first preset direction and is mounted on the operating table 7; a first clamping assembly 1 is provided on the top of the first support plate 8; a second support plate 9, which extends along the extension direction of the first support plate 8 and is mounted on the operating table 7; the second support plate 9 is spaced apart from the first support plate 8, and a second clamping assembly 2 is provided on the top of the second support plate 9.

[0027] By adopting the above technical solution, the first support plate 8 and the second support plate 9 installed on the operating table 7 respectively support the clamping components, and construct a stable double support frame to ensure clamping centering.

[0028] Please refer to Figure 1 The magnetic shielding manufacturing fixture also includes: a placement plate 10, the bottom of which is connected to the operating table 7; a first support plate 8 is movably disposed on the placement plate 10 in the direction of a second support plate 9; and a second support plate 9 is movably disposed on the placement plate 10 in the direction of a first support plate 8.

[0029] By adopting the above technical solution, the first support plate 8 and the second support plate 9 are movably arranged on the placement plate 10 to form a stepless width adjustment mechanism to adapt to silicon steel sheet groups of different sizes.

[0030] Working principle:

[0031] First, the operator places the silicon steel sheet assembly on the placement plate 10 of the operating table 7. Then, the relative distance between the first support plate 8 and the second support plate 9 on the placement plate 10 is adjusted to accommodate the width of the silicon steel sheet assembly. The first positioning bolt 4 is rotated to advance it along the second preset direction, driving the first positioning bolt 4 to move towards the silicon steel sheet assembly. Simultaneously, the second positioning bolt 6 is rotated, driving the second positioning bolt 6 to advance in the opposite direction. The first positioning bolt 4 and the second positioning bolt 6 simultaneously press the silicon steel sheet assembly from both sides. Through the multiple first positioning bolts 4 and second positioning bolts 6 spaced apart along the first preset direction, a multi-point balanced pressure is formed. After clamping is completed, the silicon steel sheet assembly is tightened as a whole by bolts passing through it and fixing it to the fixing plate. Finally, the tooling is removed to obtain a gapless inclined magnetic shielding structure.
