Description

Technical Field

[0001] The utility model relates to the technical field of transformer production and processing equipment, in particular to a clamp for transformer production. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core. Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc.

[0003] The existing square transformer housing bracket is installed by opening four straight holes at the four corners of the iron core and manually tightening the screws and nuts. This process often requires one hand to hold the screws and the other hand to fix the nuts. The two hands work together, which has the problems of low efficiency and high difficulty.

[0004] The Chinese patent with the authorization announcement number CN210006592U discloses a square transformer assembly fixture, which fixes the nut through the nut placement cavity set on the assembly fixture, places the shell bracket at the shell bracket placement position, places the iron core above the nut assembly fixture and the shell bracket, realizes the limit of the nut, the shell bracket and the iron core, and then fixes it with screws. This makes the square transformer shell bracket installation efficient.

[0005] However, the above scheme still has certain shortcomings. The clamps in the scheme can only be used in corresponding combinations with the transformers and cannot be used universally. The installation of each square transformer housing bracket requires the use of a corresponding clamp, which makes the cost too high and the utilization rate of a single clamp is limited.

[0006] Therefore, a universal clamp is needed that can adapt to the installation of square transformer housing brackets of different models and improve the flexibility of use. Utility Model Content

[0023] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0025] like Figure 1-Figure 4 As shown, a clamp for transformer production is used for fixing a square transformer 1 and a mounting shell 2. The two mounting shells 2 are fixed to the two sides of the square transformer 1 by bolts 7 and nuts 8. The clamp comprises a base plate 3 and a limiting column 4, a locking assembly 5 and a supporting column 6 located on the base plate 3. A suction cup 602 is provided at the bottom of the supporting column 6. The supporting column 6 is connected to the base plate 3 through the suction cup 602. A limiting hole is provided above the supporting column 6. The nut 8 is located in the limiting hole. A plurality of the supporting columns 6 are correspondingly located below the screw holes of the mounting shell 2 and the square transformer 1. The square transformer 1 is fixed by the limiting column 4 and the locking assembly 5.

[0026] Through the above technical solution, the position of the square transformer 1 when placed is determined by the limiting column 4, and then according to the position of the screw holes of the square transformer 1 and the mounting shell 2, a plurality of support columns 6 are fixed on the bottom plate 3 in advance through the suction cup 602, and then the nut 8 is placed in the limiting hole in advance; then the mounting shell 2 is dropped on the support column 6, at which time the screw hole of the mounting shell 2 is aligned with the limiting hole, and then the square transformer 1 is dropped on the mounting shell 2, at which time the screw hole of the square transformer 1 is aligned with the screw hole of the mounting shell 2, and finally the upper mounting shell 2 is dropped on the square transformer 1 and aligned. At this time, the mounting shell 2 and the square transformer 1 are both supported by the support column 6, and are limited by the limiting column 4 and the locking assembly 5. Finally, the square transformer 1 and the mounting shell 2 can be locked by screwing in the bolt 7. When the bolt 7 and the nut 8 cooperate, it is no longer necessary to manually fix the nut 8 on one side, which improves the installation efficiency of the bolt 7. At the same time, according to different models of square transformers 1 and mounting shells 2, the position of the support column 6 can be flexibly adjusted according to the actual position of the screw hole, so that the nut 8 can be placed in advance and play a supporting role for the square transformer 1 and the mounting shell 2.

[0027] Furthermore, the limiting hole is located at the center of the support column 6, and the limiting hole is a stepped hole. The limiting hole includes a placement hole 601 and an insertion hole 603. The size of the limiting hole matches the size of the nut 8. The insertion hole 603 is located below the placement hole 601, and the hole diameter of the insertion hole 603 is larger than the rod diameter of the bolt 7 and smaller than the outer diameter of the nut 8.

[0028] Through the above technical scheme, the size of the nut 8 is adapted to the size of the placement hole 601. When the nut 8 is placed in the placement hole 601, it will be supported and limited by the step between the insertion hole 603 and the placement hole 601. When the bolt 7 and the nut 8 are matched, the relative rotation of the nut 8 is limited by the placement hole 601, which facilitates the connection between the bolt 7 and the nut 8. At the same time, the bolt 7 and the nut 8 will extend into the insertion hole 603 after matching, ensuring that the top of the bolt 7 can be completely tightened against the mounting shell 2, thereby improving the connection strength.

[0029] At the same time, the support column 6 can be provided with limiting holes adapted to nuts 8 of different specifications. When the square transformer 1 and the mounting housing 2 are installed by bolts 7 and nuts 8 of different specifications, the support column 6 below can be replaced for flexible adaptation.

[0030] Furthermore, magnets are provided on both sides of the limiting hole at the top of the support column 6 , and the magnet 604 is embedded in the support column 6 and fixed to the support column 6 .

[0031] Through the above technical solution, when the support column 6 is positioned, the screw hole of the mounting shell 2 is aligned with the limiting hole and then placed on the support column 6, and the mounting shell 2 is adsorbed and fixed to the support column 6 by the magnet 604 to avoid displacement of the mounting shell 2 when the square transformer 1 is placed later, making it convenient for the bolt 7 to be inserted and matched with the nut 8.

[0032] Furthermore, the locking assembly 5 is located on a side of the square transformer 1 away from the limiting column 4 , and the locking assembly 5 includes a support plate 501 and a locking screw 502 , and the locking screw 502 is threadedly connected to the support plate 501 .

[0033] Furthermore, the limiting column 4 is an L-shaped structure, the limiting column 4 is vertically fixed on the bottom plate 3 , and one corner of the square transformer 1 abuts against the inner concave surface of the limiting column 4 .

[0034] Through the above technical solution, the position of the square transformer 1 and one corner of the mounting housing 2 is limited by the limiting column 4, which facilitates the determination of the adsorption position of the support column 6. After the mounting housing 2 and the square transformer 1 are placed on the support column 6, the locking screw 502 is tightened to make the locking screw 502 and the square transformer 1 tightly pressed against each other, and the square transformer 1 is fixed in the middle by the locking screw 502 and the limiting column 4. The friction force of the tightening of the locking screw 502 ensures that the square transformer 1 will not shake, so as to avoid the square transformer 1 from being deviated when the bolt 7 is screwed in later.

[0035] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be protected by the claims attached to the utility model.
