Description

Technical Field

[0001] This invention relates to the field of power transformer manufacturing technology, specifically to a positioning fixture for power transformer products. Background Technology

[0002] A power transformer is an electrical device primarily used to convert alternating current from one voltage level to another. It operates on the principle of electromagnetic induction and consists of two or more windings, a primary winding connected to the power source and a secondary winding that outputs the required voltage. Transformers are widely used in power systems and electronic equipment to raise or lower voltage, thereby meeting the voltage requirements of different devices or systems and ensuring the safe and efficient transmission of electrical energy.

[0003] In the processes of coil winding, core stacking, insulation treatment, and assembly inspection of power transformers, tooling fixtures are required to position and place the power transformers to ensure their stability. However, existing tooling fixtures for positioning and placing power transformers are usually one-piece designs and typically only have one placement station. They cannot be adjusted in number according to actual process requirements, resulting in low adaptability. The only solution is to develop tooling fixtures of different specifications to meet the needs of different station numbers, which incurs high costs. Summary of the Invention

[0004] The purpose of this invention is to provide a positioning fixture for power transformer products to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A positioning fixture for power transformer products includes assembly module A, assembly module B, and several assembly modules C. The assembly modules C are assembled in a straight line. Assembly module A is assembled on the side of one side of assembly module C, and assembly module B is assembled on the side of the other side of assembly module C, forming a long strip-shaped whole. The top of assembly module A, assembly module B, and assembly module C all have positioning bosses A. Each positioning boss A has a positioning groove. Each positioning groove has a positioning boss B fixed on its inner sidewall. The bottom surface of the positioning boss B abuts and fits against the top surface of assembly module A, assembly module B, and assembly module C respectively. The upper surface of each positioning boss B is lower than the upper surface of the positioning boss A.

[0007] Therefore, according to actual needs, a corresponding number of assembly modules C can be selected and assembled sequentially between assembly modules A and B to provide different numbers of positioning and placement stations to meet the needs of actual processes, effectively improving the adaptability of positioning fixtures. Moreover, the matching assembly design eliminates the need to develop multiple sets of fixtures and tooling, reducing production input costs.

[0008] Preferably, one side of assembly module A and each assembly module C is provided with a sliding slot, and the other side of assembly module B and each assembly module C is provided with a sliding strip. When the whole assembly is assembled, each sliding strip can be slidably locked into the corresponding sliding slot.

[0009] By using sliding clips to slide and fit into sliding slots, assembly modules A and C, C and C, and B and C can be assembled together, making the overall assembly and disassembly convenient and quick.

[0010] Preferably, the back of assembly module B and each assembly module C is provided with a positioning strip extending to one side, and the back of assembly module A and each assembly module C is provided with a locking hole B. Each positioning strip is fixed with a locking rod. During the overall assembly, each locking rod is matched and inserted into the corresponding locking hole B.

[0011] Preferably, the cross-section of the sliding slot is T-shaped, and the cross-section of the sliding strip is T-shaped to match the sliding slot.

[0012] Preferably, assembly modules A, B, and C have the same length, width, and height. When the positioning strip on assembly module B abuts against the back of the adjacent assembly module C, assembly module B remains flush with the adjacent assembly module C. When the positioning strip on assembly module C abuts against the back of the adjacent assembly module C, assembly module C remains flush with the adjacent assembly module C. When the positioning strip on assembly module C abuts against the back of the adjacent assembly module A, assembly module C remains flush with the adjacent assembly module A.

[0013] Preferably, the top of assembly module A and each assembly module C is provided with a vertically downward extending insertion hole that corresponds to and passes through the sliding slot. A pin is slidably inserted into each insertion hole. Each sliding slot is provided with a corresponding slot A for the pin to be inserted into, so as to realize the snap-fit ​​of the sliding slot. When assembly module A, assembly module B and each assembly module C are all kept at the same level, each pin can be aligned with the corresponding slot A.

[0014] Preferably, each insertion hole has an enlarged relief end hole at the top with an inner diameter larger than that of the insertion hole, and the pin top has a handle that can be hidden and stored in the relief end hole.

[0015] Preferably, each of the assembly modules A, B, and C has a pair of clearance holes at its top, and each of the assembly modules A and B has an extended strip fixed to the side of each module that is far apart from the other.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0017] 1. According to actual needs, the present invention can select a corresponding number of assembly modules C and assemble them sequentially between assembly modules A and assembly modules B to provide different numbers of positioning and placement stations to meet the needs of actual processes, effectively improve the adaptability of positioning fixtures, and the matching assembly design eliminates the need to develop multiple sets of fixtures and tooling, reducing production input costs.

[0018] 2. The present invention utilizes the insertion of the clamp rod into the corresponding clamp hole B to provide a further limiting support effect, ensuring a more secure connection between two adjacent assembly modules, thereby ensuring stability during use.

[0019] 3. The present invention achieves a positioning effect by setting positioning strips. By using positioning strips to abut and fit against the back of assembly module A and assembly module C, it can ensure that each assembly module remains flat, ensuring the flatness and aesthetics of the overall appearance of the fixture. In addition, the positioning effect of the positioning strips can ensure that each pin can be smoothly aligned and inserted into the corresponding card hole A, achieving two goals at once.

[0020] 4. After the assembly modules are assembled, the pin is inserted into the corresponding card hole A to limit the sliding strip and prevent it from sliding out of the sliding slot at will, thus ensuring the overall stability of the fixture. In addition, the pin is set vertically, and during use, it can automatically fall into the card hole A due to gravity, and will not fall out at will, thus ensuring high stability.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8 This invention provides a positioning fixture for power transformer products, including assembly module A1, assembly module B2, and several assembly modules C3. The assembly modules C3 are assembled in a straight line. Assembly module A1 is assembled on the side of one side of assembly module C3, and assembly module B2 is assembled on the side of the other side of assembly module C3, forming a long strip-shaped whole. Multiple assembly modules C3 are provided, and according to actual needs, an appropriate number of assembly modules C3 can be selected and sequentially assembled between assembly module A1 and assembly module B2 to provide different numbers of positioning positions to meet the needs of actual processes, effectively improving the adaptability of the positioning fixture. Moreover, the matching assembly design eliminates the need to develop multiple sets of fixtures and tooling, reducing production input costs.

[0032] Each assembly module A1 and each assembly module C3 has a sliding slot 4 on one side, and each assembly module B2 and each assembly module C3 has a sliding strip 5 on the other side. During overall assembly, each sliding strip 5 can slide and engage with its corresponding sliding slot 4. By sliding and engaging the sliding strip 5 on one side of assembly module C3 into the sliding slot 4 on the side of assembly module A1, the assembly module C3 and the sliding slot 4 are assembled. The moving matching card is inserted into the sliding slot 4 on the side of another assembly module C3 to realize the assembly of assembly module C3 with assembly module C3. By sliding the sliding matching card 5 on the side of assembly module B2 into the sliding slot 4 on the side of assembly module C3, the assembly of assembly module B2 and assembly module C3 is realized. This makes the disassembly and assembly process between assembly module A1 and assembly module C3, between assembly module C3 and assembly module C3, and between assembly module B2 and assembly module C3 convenient and quick.

[0033] Specifically, the back of assembly module B2 and each assembly module C3 is provided with a positioning strip 6 extending to one side, and the back of assembly module A1 and each assembly module C3 is provided with a locking hole B611. Each positioning strip 6 is fixed with a locking rod 61. During the overall assembly, each locking rod 61 is matched and inserted into the corresponding locking hole B611. The locking rod 61 is inserted into the corresponding locking hole B611 to provide a further limiting support effect, ensuring a more secure connection between adjacent assembly modules, so as to ensure stability during use.

[0034] In addition, the cross-section of the sliding slot 4 is T-shaped, and the cross-section of the sliding strip 5 is a T-shaped that matches the sliding slot 4. Designing the cross-sections of both the sliding slot 4 and the sliding strip 5 as mutually matching T-shapes effectively limits the movement and prevents adjacent assembly modules from separating arbitrarily.

[0035] Each of the assembly modules A1, B2, and C3 has a positioning boss A02 on its top. Each positioning boss A02 has a positioning groove 021 for the power transformer product to be fitted into. A positioning boss B03 is fixed on the inner wall of each positioning groove 021. The bottom surface of the positioning boss B03 abuts against the top surface of each of the assembly modules A1, B2, and C3. The upper surface of each positioning boss B03 is lower than the upper surface of the positioning boss A02, forming a stepped structure to accommodate the structural deformation of the power transformer. Each of the assembly modules A1, B2, and C3 has a pair of clearance holes 04 on its top for the protrusions on the edge transformer to be fitted into, improving the compatibility with the power transformer. An extension strip 01 is fixed on the side of each assembly module A1 and B2 that is far apart from each other, making it convenient to handle and move the whole unit by hand.

[0036] Specifically, assembly modules A1, B2, and C3 are of equal length, width, and height. When the positioning strip 6 on assembly module B2 abuts against the back of the adjacent assembly module C3, assembly module B2 remains flush with the adjacent assembly module C3. When the positioning strip 6 on assembly module C3 abuts against the back of the adjacent assembly module C3, assembly module C3 remains flush with the adjacent assembly module C3. When the positioning strip 6 on assembly module C3 abuts against the back of the adjacent assembly module A1, assembly module C3 remains flush with the adjacent assembly module A1. This ensures the flatness and aesthetics of the overall appearance of the fixture.

[0037] Specifically, each assembly module A1 and each assembly module C3 has a vertically downward extending insertion hole 31 at its top, which corresponds to and passes through the sliding slot 4. Each insertion hole 31 has a pin 7 slidably inserted into it. Each sliding strip 5 has a corresponding locking hole A51 for the pin 7 to be inserted into, so as to achieve the locking of the sliding strip 5. When the assembly modules A1, B2 and C3 are all aligned, each pin 7 can be aligned with the corresponding locking hole A51. After the assembly modules are aligned, the pin 7 is inserted into the corresponding locking hole A51 to limit the sliding strip 5 and prevent it from sliding out of the sliding slot 4 at will, thus ensuring the overall stability of the fixture. In addition, the pin 7 is vertically set, and during use, it can automatically fall into the locking hole A51 due to gravity, and will not fall out at will, thus ensuring high stability.

[0038] In addition, the positioning effect of the positioning strip 6 can ensure that each pin 7 can be smoothly aligned and inserted into the corresponding card hole A51, achieving two goals at once.

[0039] Specifically, each insertion hole 31 has an enlarged relief end hole 311 at its top, with an inner diameter larger than that of the insertion hole 31. The pin 7 has a handle 71 at its top that can be hidden and housed within the relief end hole 311. The handle 71 is flat, facilitating pulling by hand. The relief end hole 311 has a large diameter, and there is a gap between it and the handle 71, allowing space for fingers to enter and exit, making it convenient to grip the handle 71 for operation. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Therefore, all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
