Description

Technical Field

[0001] The present invention relates to the technical field of tooling fixtures, and in particular to a fixture for clamping and fixing a transformer frame and a clamping method thereof. Background Art

[0002] With the rapid development of electronic technology, electronic devices have become widely used in daily life, industrial control, communications, new energy, and other fields. To meet the power supply requirements and operating environments of different electronic devices, the types and specifications of transformers are becoming increasingly diverse, and the corresponding transformer bobbins also have different structures and sizes. During the transformer production process, the bobbin must be precisely fixed to the winding machine to ensure winding accuracy and consistency. Therefore, specialized fixtures are often required to adapt to bobbins of different specifications.

[0003] Currently, transformer bobbins on the market come in complex shapes and a wide range of sizes, including but not limited to vertical, horizontal, square, circular, and multi-slot structures. To accommodate the winding requirements of different bobbins, manufacturers typically need to equip various fixtures to match bobbins of varying sizes. However, this model presents the following problems in actual production:

[0004] High R&D costs: During new product development or small-batch trial production, only a small number of samples may be needed for testing. Customizing or purchasing new fixtures for this purpose not only increases production costs but also prolongs the R&D cycle, slowing down product iterations.

[0005] Complex inventory management: Since transformer bobbins of different specifications require different fixtures, manufacturers need to stock a large number of fixtures to meet production demand, which increases inventory management pressure and occupies funds and storage space.

[0006] Low switching efficiency: When producing transformers of different models, frequent replacement of fixtures will affect production efficiency and increase debugging time, which is especially detrimental to the flexible production of small batch and multi-variety orders.

[0007] Therefore, there is an urgent need in the existing technology for a fixture solution that is highly versatile and can quickly adapt to transformer skeletons of different specifications, so as to reduce R&D and production costs, improve winding efficiency, and adapt to the flexible manufacturing needs of small batches and multiple varieties.

[0008] SUMMARY OF THE INVENTION

[0009] The technical problem solved by the present invention is that the existing fixture structure for transformer skeleton is fixed and has low applicability.

[0020] In one embodiment of the present invention, the support assembly includes a slider and a support rod, the slider is slidably engaged with the adjustment rail, and the support rod is detachably connected to the slider.

[0021] In one embodiment of the present invention, the cross-section of the support rod is square, circular or fan-shaped.

[0022] In one embodiment of the present invention, a locking structure is provided between the support assembly and the adjustment rail.

[0023] A method for clamping and fixing a transformer frame based on the above-mentioned fixture comprises the following steps:

[0024] Determine the specifications and shape of the target transformer bobbin and obtain relevant processing parameters;

[0025] Determine the clamping scheme according to the target transformer skeleton, and select the required tooling body with the target number of adjustment rails and the corresponding number of support rods with the shape that meets the clamping scheme according to the clamping scheme;

[0028] The support assembly is locked by a locking structure.

[0029] According to the present invention, a fixture for clamping and fixing a transformer frame and a clamping method thereof have at least one of the following technical effects:

[0030] This application includes: a tooling body, an adjustment rail, and a support assembly. The support assembly is movably connected to the tooling body through the adjustment rail, so that the position of the support assembly can be adjusted as needed, and can adapt to the clamping and fixation of transformer skeleton products of different specifications and models.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] See also Figure 1-4 The present invention is a jig for clamping and fixing a transformer skeleton, comprising: a tooling body 10, an adjustment rail 20, and a support assembly 30. The tooling body 10 is used as the main support structure and base structure of the tooling body. It includes at least one flat working surface for supporting the transformer skeleton to be processed; the tooling body 10 can be a columnar structure, especially a cylindrical structure. The tooling body 10 is provided with a connecting structure 11 for connecting to a winding machine, and the connecting structure 11 can be a protruding rod-shaped, plate-shaped structure fixedly provided on the tooling body 10, or a concave ring-shaped, hole structure. As an example, the connecting structure 11 is a connecting hole opened on the side of the tooling body 10. It can be plugged into the protruding structure on the equipment through the connecting hole, or it can be provided with a thread and connected to the screw provided on the winding machine by a threaded connection.

[0043] See also Figure 1-4 In one embodiment of the present invention, at least one adjustment rail 20 is provided on the tool body 10 for cooperating with the mounting of a support assembly 30 and for enabling the support assembly 30 to be adjusted. The adjustment rail 20 is provided on the working surface of the tool body 10. Specifically, the number of adjustment rails can be one or multiple, non-overlapping rails. When multiple adjustment rails are provided, they can be arranged in parallel or in a cross-arranged manner. When a cross-arranged rail is provided, the rails can intersect at the same center point and be evenly distributed.

[0044] See also Figure 1-4 In one embodiment of the present invention, the specific form of the adjustment rail 20 can be selected according to the situation. For example, the adjustment rail 20 can be a slide groove formed by a partial depression on the working surface of the tooling body 10, that is, a slide groove is provided on the working surface at the top of the tooling body 10 as the adjustment rail 20. For another example, the adjustment rail 20 can be a slide rail formed by a partial protrusion on the working surface, and for another example, a guide plate 21 can be fixedly provided on the working surface, and the space between the two parallel guide plates 21 forms a slide groove. As a preferred example, the adjustment rail 20 is a slide groove structure formed by a depression, so that the transformer skeleton product can be placed more conveniently.

[0045] See also Figure 1-4 In one embodiment of the present invention, the support assembly 30 is slidably matched with the tooling body 10 through the adjustment rail 20 and is used to clamp the inner wall of the transformer frame. The number of the support assemblies 30 is at least two groups. The corresponding relationship with the number of the adjustment rails 20 is as follows: one adjustment rail 20 is provided with two groups of support assemblies 30, and the other adjustment rails 20 are provided with one or two groups of support assemblies 30. Specifically, when the number of the adjustment rails 20 is one, at least two groups of support assemblies 30 are provided in the adjustment rail 20. When the number of the adjustment rails 20 is more than one, except for one adjustment rail 20 being provided with two groups of support assemblies 30, the other adjustment rails 20 can be provided with one or two groups of support assemblies 30.

[0046] See also Figure 1-4 In one embodiment of the present invention, the support assembly 30 may include a slider 31 and a support rod 32. The slider 31 is movably matched with the adjustment rail 20. The support rod 32 and the slider 31 may be fixedly connected. When in use, the support rod 32 can be replaced together with the slider 31. Of course, as a preferred example, the support rod 32 can be detachably connected to the slider 31. In this way, the support rod 32 can be disassembled and replaced as needed. The connection between the support rod 32 and the slider 31 can be plug-in, threaded, etc. As an example, the slider 31 has a threaded connector, and the end of the support rod 32 is provided with a corresponding threaded hole.

[0047] See also Figure 1-4In one embodiment of the present invention, the shape of the support rod 32, that is, the profile of the cross section, can be set according to the actual situation, that is, it can be set according to the shape of the inner wall of the target transformer skeleton, so as to better contact the inner wall of the transformer skeleton and ensure the stability of clamping the target product. As an example, the cross-sectional shape of the support rod 32 can be square, circular or fan-shaped. When the cross-sectional profile shape is fan-shaped, it is preferred that the arc profile of the support rod 32 contacts the inner wall of the transformer skeleton to ensure the clamping stability, that is, when setting the support rod 32, the arc surface of the support rod 32 can be facing outward (such as Figure 2 ).

[0048] See also Figure 1-4 In one embodiment of the present invention, the support assembly 30 can be secured relative to the adjustment rail 20 through frictional resistance. When the position of the support assembly 30, i.e., the position of the slider 31, needs to be adjusted, an external force can be applied by oscillating the support assembly 30 / slider 31 to cause it to slide. When clamping the transformer bobbin product, the support rod 32 is constrained by the transformer bobbin, increasing the pressure on the contact surface with the tooling body 10 and the static friction resistance, thereby ensuring a certain degree of stability. As a preferred example, a locking structure can be provided between the support assembly 30 and the adjustment rail 20 to lock the support assembly 30 after the position adjustment is completed. The locking structure can be a pin structure, a screw structure, or a bolt structure. As one example, the slider 31 has a through hole (threaded hole) with a pin (screw) movably disposed therein. When adjusting the position of the slider 31, the pin (screw) is pulled out (unscrewed) to release the constraint on the slider 31. After adjustment, the pin (screw) is inserted into the through hole (threaded hole) so that it abuts the corresponding position of the adjustment rail 20, thereby completing the locking between the two. As another example, when the adjustment rail 20 is composed of two parallel guide plates 21, a locking groove 22 (such as Figure 3 ), a locking hole (such as Figure 4 ), and then a bolt is set to pass through the locking groove 22 and inserted into the locking hole, and the position of the slider 31 is locked / released by tightening / loosening the nut.

[0049] Working principle of the present invention:

[0050] The method for clamping and fixing a transformer frame using the jig of the present application includes the following steps: determining the specifications and shape of the target transformer frame, obtaining relevant processing parameters, such as the shape and size of the inner wall of the target product, to determine the optimal or preferred clamping solution; determining the clamping solution based on the target transformer frame, such as what specifications and sizes of the tooling body 10 to select, how many sets of support assemblies 30 to use for fixing the transformer frame, and how many adjustment rails 20 the tooling body 10 needs to have. As one example, if the inner wall of the target transformer frame is circular, a tooling body 10 with two adjustment rails 20 can be selected, and three or four sets of support assemblies 30 can be used for clamping and fixing. When the inner wall contour of the transformer frame is a special shape or a special shape (such as an elliptical contour or an irregular contour of a transformer frame product), since the number and position of the support assemblies 30 are adjustable, multiple sets of support assemblies 30 can be selected so that the support rods 32 contact the corresponding positions of the inner wall to ensure stable clamping of the target product. If the inner wall is pentagonal, five groups of support assemblies 30 can be set up, and five support rods 32 can be placed at the five corner positions. The shape of the support rods 32 can also be set to be consistent with the shape of the contact position to ensure clamping stability.

[0051] After the clamping scheme is determined, the required tooling body 10 with the target number of adjustment rails 20 and the support assembly 30 with the corresponding number of support rods 32 that conform to the clamping scheme are selected according to the clamping scheme; the support assembly 30 is assembled on the tooling body 10 to form a jig, and the tooling body 10 is installed on the winding machine; before clamping the target product, the position of the support assembly 30 needs to be adjusted so that the product can be sleeved on the outside of several support rods 32, and then the target transformer frame is placed on the tooling body 10, and then the position of the support assembly 30 is adjusted so that the support rods 32 are close to the inner wall of the transformer frame, and then the transformer frame is clamped and fixed; finally, the support assembly 30 is locked by the locking structure to complete the clamping and fixation of the transformer frame, and then the winding process on the frame is started.
