Description

Technical Field

[0001] The invention relates to the technical field of power transformer production, and in particular to a positioning fixture for power transformer products. Background Art

[0002] A power transformer is an electrical device that is mainly used to convert alternating current from one voltage level to another. It works on the principle of electromagnetic induction and contains two or more windings, primary and secondary. The primary winding is connected to the power supply, and the secondary winding outputs the required voltage. Transformers are widely used in power systems and electronic equipment to increase or decrease the 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 the power transformer, it is necessary to use tooling to position and place the power transformer to ensure the stability of the power transformer. However, the existing tooling for positioning and placing the transformer power supply is usually an integrated design and usually has only one placement station. The number of stations cannot be adjusted according to the actual process requirements, and the degree of adaptability is low. The requirements for the number of different stations can only be met by developing tooling of different specifications, which results in a high cost investment. Summary of the invention

[0004] The purpose of the present invention is to provide a positioning fixture for power transformer products to solve the technical problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions.

[0006] A positioning fixture for power transformer products comprises an assembling module A, an assembling module B and a plurality of assembling modules C, wherein the plurality of assembling modules C are assembled in pairs in a straight line, the assembling module A is assembled on the side of the assembling module C on one side, and the assembling module B is assembled on the side of the assembling module C on the other side to form a long strip-shaped whole, the tops of the assembling modules A, B and C are all provided with positioning bosses A, each positioning boss A is provided with a positioning groove, and a positioning boss B is fixed on the inner side wall of each positioning groove, the bottom end surface of the positioning boss B is respectively in contact with and fits the top surfaces of the assembling modules A, B and C, and the upper end surface of each positioning boss B is lower than the upper end surface of the positioning boss A.

[0013] Preferably, the tops of the assembly modules A and each assembly module C are provided with insertion holes extending vertically downward and corresponding to the sliding card slots, and a latch is slidably inserted in each insertion hole. Each sliding card strip is provided with a card hole A for the corresponding insertion of the latch to achieve the card connection of the sliding card strip. When the assembly module A, the assembly module B and each assembly module C are kept flush, each latch can be aligned with the corresponding card hole A position respectively.

[0014] Preferably, the top of each insertion hole is enlarged to provide a yielding end hole whose inner diameter is larger than the inner diameter of the insertion hole, and the top of the latch has a gripping handle that can be hidden and received in the yielding end hole.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 8 The present invention provides a positioning fixture for power transformer products, including an assembling module A1, an assembling module B2 and a plurality of assembling modules C3. The plurality of assembling modules C3 are assembled in pairs in a straight line. The assembling module A1 is assembled on the side of the assembling module C3 on one side, and the assembling module B2 is assembled on the side of the assembling module C3 on the other side to form a long strip-shaped whole. A plurality of assembling modules C3 are provided. According to actual needs, a corresponding number of assembling modules C3 can be selected and assembled in pairs between the assembling module A1 and the assembling module B2 in sequence to provide different numbers of positioning and placement stations to meet the needs of actual processes, effectively improve the adaptability of the positioning fixture, and the matching pair assembly design does not require the development of multiple sets of fixtures and tooling, thereby reducing production input costs.

[0032] The assembling module A1 and each assembling module C3 are provided with a sliding card slot 4 on one side, and the assembling module B2 and each assembling module C3 are provided with a sliding card strip 5 on the other side. When the whole is assembled, each sliding card strip 5 can be slidably mounted in the corresponding sliding card slot 4. The assembling module C3 and the sliding card slot 4 are assembled by sliding the sliding card strip 5 on one side of the assembling module C3 into the sliding card slot 4 on the side of the assembling module A1. The assembling modules C3 and C3 are assembled in pairs by sliding the sliding card strip 5 on one side of the assembling module B2 into the sliding card slot 4 on the side of the assembling module C3, so that the assembly and disassembly process between the assembling modules A1 and the assembling modules C3, between the assembling modules C3 and the assembling modules B2 and C3 is convenient and quick enough.

[0033] In addition, the cross-section of the sliding slot 4 is T-shaped, and the cross-section of the sliding strip 5 is T-shaped that matches the sliding slot 4. The cross-sections of the sliding slot 4 and the sliding strip 5 are designed to be T-shaped that match each other, which has an effective limiting effect and prevents arbitrary separation between two adjacent assembly modules.

[0034] The tops of the assembling modules A1, B2 and C3 are all provided with positioning bosses A02, and each positioning boss A02 is provided with a positioning groove 021 for the power transformer product to be matched and placed, and the inner wall of each positioning groove 021 is fixed with a positioning boss B03, and the bottom surface of the positioning boss B03 is respectively in contact with and fits with the top surfaces of the assembling modules A1, B2 and C3, and the upper end surface of each positioning boss B03 is lower than the upper end surface of the positioning boss A02, forming a stepped structure to adapt to the structural deformation of the power transformer, and the tops of the assembling modules A1, B2 and C3 are all provided with a pair of clearance holes 04 for the protrusions on the edge transformer to be matched and inserted, so as to improve the degree of adaptation with the power transformer, and the sides of the assembling modules A1 and B2 away from each other are fixed with extension strips 01, which are convenient for hand-held transportation and transfer of the whole.

[0035] Specifically, the back of the assembly module B2 and each assembly module C3 is provided with a positioning strip 6 extending to one side, and the back of the assembly module A1 and each assembly module C3 is provided with a clamping hole B611. A clamping rod 61 is fixed on each positioning strip 6. When the overall assembly is assembled, each clamping rod 61 is respectively matched and inserted into the corresponding clamping hole B611. The clamping rod 61 is inserted into the corresponding clamping hole B611 to provide a further limiting support effect, thereby ensuring that the connection between the two adjacent assembly modules is more firm, thereby ensuring stability during use.

[0036] Specifically, the assembly module A1, the assembly module B2 and the assembly module C3 are structures of equal length, width and height. When the positioning strip 6 on the assembly module B2 is in contact with the back of the adjacent assembly module C3, the assembly module B2 remains flush with the adjacent assembly module C3. When the positioning strip 6 on the assembly module C3 is in contact with the back of the adjacent assembly module C3, the assembly module C3 remains flush with the adjacent assembly module C3. When the positioning strip 6 on the assembly module C3 is in contact with the back of the adjacent assembly module A1, the assembly module C3 remains flush with the adjacent assembly module A1, so as to ensure the flatness and aesthetics of the overall appearance of the fixture.

[0037] Specifically, the tops of the assembling modules A1 and each of the assembling modules C3 are provided with insertion holes 31 extending vertically downward and corresponding to the sliding card slots 4. A latch 7 is slidably inserted in each of the insertion holes 31. Each of the sliding card strips 5 is provided with a card hole A51 for the latch 7 to be inserted into, so as to realize the card connection of the sliding card strip 5. When the assembling modules A1, the assembling modules B2 and each of the assembling modules C3 are kept flush, each of the latches 7 can be aligned with the corresponding card hole A51 respectively. After the assembling modules are assembled, the latch 7 is inserted into the corresponding card hole A51, which can limit the sliding card strip 5 and prevent the sliding card strip 5 from sliding out of the sliding card slot 4 at will, thereby ensuring the overall firmness of the fixture. In addition, the latch 7 is vertically arranged. When in use, it can automatically fall into the card hole A51 due to the action of gravity and will not fall out at will, with a high degree of stability.

[0038] In addition, the positioning effect of the positioning strip 6 can ensure that each latch pin 7 can be smoothly aligned and inserted into the corresponding clamping hole A51, thus killing two birds with one stone.

[0039] Specifically, each insertion hole 31 is enlarged at the top to provide a yield end hole 311 whose inner diameter is larger than that of the insertion hole 31. The top of the latch 7 is provided with a pinch handle 71 that can be hidden and accommodated in the yield end hole 311. The pinch handle 71 is flat, which is convenient for hand-pinching and pulling. The yield end hole 311 has a large diameter, and there is a gap between the pinch handle 71, which makes room for fingers to enter, making it convenient to pinch the pinch handle 71 for operation.
