Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a jig for producing transformers. Background Technique

[0002] The production process of toroidal transformers successively includes core wrapping with polyester film, primary winding, de-lacquering, dipping in varnish, wiring, sleeving, no-load testing, semi-finished product wrapping with polyester film, secondary winding, wiring, voltage testing, wrapping with Marlex glue, labeling, and semi-finished product wrapping with polyester film.

[0003] For example, the application number: CN202022311380.4. The utility model relates to the technical field of jigs, in particular to a jig for transformer production, including a mounting plate, a transformer jig and a rubber ring bracket oppositely arranged on the mounting plate, a transformer mounting seat and a rubber ring mounting seat for mounting the transformer jig and the rubber ring bracket. A transformer rotating shaft is rotatably connected to the transformer jig, and one end of the transformer rotating shaft extends to one side of the transformer jig to drive and connect a glue pasting mechanism. A rubber ring rotating shaft is rotatably connected to the rubber ring bracket; in practical applications, the inner ring of the toroidal transformer is sleeved on the transformer rotating shaft, and the Marlex tape is sleeved on the rubber ring rotating shaft. The joint of the Marlex tape is adhered to the outer edge of the toroidal transformer. The glue pasting mechanism drives the transformer rotating shaft to rotate one week. As the rubber ring rotating shaft rotates, the Marlex tape can be wound around the outer edge of the toroidal transformer for one week, and then the Marlex glue can be pasted; the structure of the utility model is simple, the pasting is uniform, the use is convenient, and the production efficiency is high.

[0004] Based on the retrieval of the above patent and the combination with the equipment in the prior art, it is found that when the above equipment is applied, although it can solve the problem that after voltage testing, a circle of Marlex glue needs to be pasted on the outer edge of the toroidal transformer. In the prior art, the pasting of Marlex glue is to hold the inner ring of the toroidal transformer with one hand and stick the Marlex glue on the outer edge of the toroidal transformer with the other hand. While sticking, the other hand manually rotates the toroidal transformer to make the Marlex glue stick around the outer edge of the toroidal transformer, and then manually cut the Marlex glue; due to manual pasting, if the hand shakes during the pasting process, it will cause skew, resulting in a large difference in the appearance of the toroidal transformer after pasting and extremely low production efficiency. However, during the use process, neither the Marlex glue jig nor the transformer jig has a stable clamping structure, so that whether the Marlex tape is sleeved into the Marlex glue jig body or the transformer is sleeved into the transformer jig body, when the knob is rotated for winding, both the Marlex glue and the toroidal transformer will shake, resulting in the rubber ring being pasted crookedly.

[0012] Preferably, on the front side of the right side of the bottom plate, a placement block is fixedly connected, and the bottom of the surface of the ring-shaped handle is slidably connected to the inner wall of the placement block.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By setting the connecting rod and the first spring in the present utility model, when the transformer fixture body is sleeved on the ring-shaped transformer and the Mara glue fixture body is sleeved on the Mara glue, the restoring force generated by the first spring previously squeezed by the connecting rod and the support block restores the first spring and pushes the connection, so that the transformer fixture body and the Mara glue fixture body stably clamp the ring-shaped transformer and the Mara glue, solving the problem that neither the Mara glue fixture nor the transformer fixture has a stable clamping structure, so that whether the Mara glue is sleeved into the Mara glue fixture body or the transformer is sleeved into the transformer fixture body, when the knob is rotated for winding, the Mara glue and the ring-shaped transformer will shake, resulting in the glue ring being pasted crookedly, and achieving the effect of assisting the winding of the Mara glue.

[0015] 2. By setting the limiting mechanism in the present utility model, when it is necessary to replace the ring-shaped transformer clamped by the transformer fixture body or the Mara glue clamped by the Mara glue fixture body and it is necessary to squeeze and limit the first spring, the user moves the connecting rod to squeeze the first spring. During the process, the L-shaped hook block moves together. When the L-shaped hook block moves to a certain position, the inclined surface on the right side of the L-shaped hook block contacts the slider on the main body frame. At this time, when moving further, the slider is affected by the extrusion of the inclined surface of the L-shaped hook block and moves upward along the track of the chute. At the same time, the second spring generates a restoring force due to the extrusion of the slider and the T-shaped frame, so that after the inclined surface of the L-shaped hook block completely passes through the slider, the restoring force of the second spring restores the second spring and pushes the slider to reset. At this time, the L-shaped hook block will be limited and fixed by the slider, so that the restoring force generated when the first spring is squeezed cannot restore the first spring and push the connecting rod to reset, so that the transformer fixture body remains in an open state to replace the ring-shaped transformer.

[0016] 3. After replacing the toroidal transformer clamped by the toroidal transformer clamp body or the mylar clamped by the mylar clamp body of the present utility model, when it is necessary to cancel the limit fixation of the slider on the L-shaped hook block and reset the connecting rod, the user holds the auxiliary handle and rotates it, causing the rotating rod to rotate. While the rotating rod rotates, it pulls the first rope, and the first rope moves along the track on the inner wall of the T-shaped frame and pulls the slider upward. At this time, the slider moves along the track of the chute, squeezing the second spring, so that the slider no longer limits and fixes the L-shaped hook block. Then, the resilience force generated when the first spring was previously squeezed by the connecting rod and the support block restores the first spring, and pushes the connecting rod to move, so that the transformer clamp body and the mylar clamp body are reset again, and the toroidal transformer and the mylar are stably clamped again.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Such as Figures 1 to 3As shown in the figure, a fixture for producing transformers provided by the utility model includes a bottom plate 1, a transformer fixture body 2, a mylar tape fixture body 3, a cutting knife 4 and a knob 5. The bottom of the mylar tape fixture body 3 is fixedly connected to the rear side of the top of the bottom plate 1. The bottom of the transformer fixture body 2 is fixedly connected to the front side of the top of the bottom plate 1. The left side of the front of the cutting knife 4 is fixedly connected to the left side of the back of the transformer fixture body 2. The left side of the knob 5 is movably connected to the right side of the transformer fixture body 2 through a pin. A connecting rod 6 is arranged on the top of the bottom plate 1. The back of the connecting rod 6 is fixedly connected to the right side of the front of the mylar tape fixture body 3. The front of the connecting rod 6 is fixedly connected to the right side of the back of the transformer fixture body 2. A support block 7 is fixedly connected to the right side of the top of the bottom plate 1. A first spring 8 is fixedly connected to the left side of the support block 7. The other end of the first spring 8 is fixedly connected to the right side of the connecting rod 6. Limit mechanisms 9 are fixedly connected to both sides of the right side of the connecting rod 6.

[0023] Reference Figure 1 and Figure 2 , the limit mechanism 9 includes an L-shaped hook block 901. The left side of the L-shaped hook block 901 is fixedly connected to both sides of the right side of the connecting rod 6. The right side of the L-shaped hook block 901 is inclined. A main body frame 902 is arranged on the right side of the connecting rod 6. The bottom of the main body frame 902 is fixedly connected to the top of the bottom plate 1. Sliding grooves 903 are opened on both sides of the top of the main body frame 902. Sliding blocks 904 are slidably connected to the inner walls of the sliding grooves 903. A T-shaped frame 905 is fixedly connected to the top of the main body frame 902. A second spring 906 is fixedly connected to the top of the sliding block 904. The other end of the second spring 906 is fixedly connected to both sides of the bottom of the T-shaped frame 905.

[0024] As a technical optimization scheme of the utility model, by setting the limit mechanism 9, when it is necessary to replace the toroidal transformer clamped by the transformer fixture body 2 or the mylar tape clamped by the mylar tape fixture body 3 and it is necessary to squeeze and limit the first spring 8, the user moves the connecting rod 6 to squeeze the first spring 8. During this process, the L-shaped hook block 901 moves together. When the L-shaped hook block 901 moves to a certain position, the inclined surface on the right side of the L-shaped hook block 901 contacts the sliding block 904 on the main body frame 902. At this time, when continuing to move, the sliding block 904 is affected by the extrusion of the inclined surface of the L-shaped hook block 901 and moves upward along the track of the sliding groove 903. At the same time, the second spring 906 generates a resilience force due to the extrusion of the sliding block 904 and the T-shaped frame 905. After the inclined surface of the L-shaped hook block 901 completely passes through the sliding block 904, the resilience force of the second spring 906 restores the second spring 906 and pushes the sliding block 904 to reset. At this time, the L-shaped hook block 901 will be limited and fixed by the sliding block 904, so that the resilience force generated when the first spring 8 is squeezed cannot restore the first spring 8 and push the connecting rod 6 to reset, so that the transformer fixture body 2 remains in an open state for replacing the toroidal transformer.

[0025] Reference Figure 1 and Figure 2 At the top of the T-shaped frame 905, a rotating rod 10 is movably connected through a shaft pin. At the top of the rotating rod 10, an auxiliary handle 11 is fixedly connected. Inside the second spring 906, a first rope 12 is arranged. One end of the first rope 12 is fixedly connected to the top of the slider 904, and the other end of the first rope 12 passes through both sides of the top of the T-shaped frame 905 and is fixedly connected to both sides of the bottom of the rotating rod 10.

[0026] As a technical optimization scheme of the present utility model, by setting the rotating rod 10, the auxiliary handle 11 and the first rope 12, after the toroidal transformer clamped by the toroidal transformer fixture body 2 or the Marabond clamped by the Marabond fixture body 3 is replaced, when the user needs to cancel the limit fixation of the slider 904 on the L-shaped hook block 901 to reset the connecting rod 6, the user holds the auxiliary handle 11 and rotates it, so that the rotating rod 10 rotates. While the rotating rod 10 rotates, it pulls the first rope 12. The first rope 12 moves along the track of the inner wall of the T-shaped frame 905 and pulls the slider 904 upward. At this time, the slider 904 moves along the track of the chute 903, compresses the second spring 906, so that the slider 904 no longer limits and fixes the L-shaped hook block 901. Then, the resilience generated when the first spring 8 was previously compressed by the connecting rod 6 and the support block 7 restores the first spring 8, and pushes the connecting rod 6 to move, so that the transformer fixture body 2 and the Marabond fixture body 3 are reset again, and the toroidal transformer and the Marabond are stably clamped again.

[0027] Reference Figure 1 Inside the first spring 8, a second rope 13 is arranged. One end of the second rope 13 is fixedly connected to the right side of the connecting rod 6, and the other end of the second rope 13 passes through the right side of the support block 7. The other end of the second rope 13 is fixedly connected with an annular handle 14.

[0028] As a technical optimization scheme of the present utility model, by setting the second rope 13 and the annular handle 14, when the user needs to move the connecting rod 6 to compress the first spring 8 to limit and fix the L-shaped hook block 901 and the slider 904 and open the transformer fixture body 2 and the Marabond fixture body 3, the user holds the annular handle 14 and pulls it, so that the second rope 13 moves along the track of the inner wall of the support block 7. At the same time, the second rope 13 pulls the connecting rod 6, so that the first spring 8 is compressed, so that the user can easily compress the first spring 8, so that the transformer fixture body 2 and the Marabond fixture body 3 are opened, preventing the user from being difficult to compress the first spring 8 by pushing the connecting rod 6 due to the resilience generated during the compression of the first spring 8.

[0029] Reference Figure 1, on both sides of the inner wall of the transformer fixture body 2, first rollers 15 are inlaid, and the first rollers 15 are distributed at equal intervals in a ring shape. On both sides of the inner wall of the mylar tape fixture body 3, second rollers 16 are inlaid, and the second rollers 16 are distributed at equal intervals in a ring shape.

[0030] As a technical optimization scheme of the present utility model, by providing the first rollers 15 and the second rollers 16, when the annular transformer fixture body 2 holds the annular transformer and the mylar tape fixture body 3 holds the mylar tape, the first rollers 15 contact the annular transformer, reducing the contact surface between the transformer fixture body 2 and the annular transformer, and at the same time not affecting the stability of the transformer fixture body 2 in holding the annular transformer. The second rollers 16 contact the mylar tape, reducing the contact surface between the mylar tape fixture body 3 and the mylar tape, and at the same time not affecting the stability of the mylar tape fixture body 3 in holding the mylar tape, preventing one end of the mylar tape from adhering to the annular transformer and making it difficult for the annular transformer and the mylar tape stably held by the elastic force of the first spring 8 to rotate when the user rotates the knob 5 to rotate the annular transformer and the mylar tape due to the excessive clamping force.

[0031] Reference Figure 3 , on the right side of the front side of the bottom of the bottom plate 1, a placement block 18 is fixedly connected, and the bottom surface of the surface of the annular handle 14 is slidably connected to the inner wall of the placement block 18.

[0032] As a technical optimization scheme of the present utility model, by providing the balls 17, when the inclined surface of the L-shaped hook block 901 contacts the slider 904 and makes the slider 9 move by extrusion, the balls 17 contact and roll with the slider 904, reducing the contact area between the inclined surface of the L-shaped hook block 901 and the slider 904, thereby reducing the friction force, making it smoother and easier for the inclined surface of the L-shaped hook block 901 to move the slider 904 by extrusion, and thus improving the working efficiency of the user.

[0033] Reference Figure 1 , on the front side of the right side of the bottom of the bottom plate 1, a placement block 18 is fixedly connected, and the bottom surface of the surface of the annular handle 14 is slidably connected to the inner wall of the placement block 18.

[0034] As a technical optimization scheme of the present utility model, by providing the placement block 18, when the user holds the annular handle 14 and pulls the second rope 13 to squeeze and limit the first spring 8, and then the user puts the annular handle 14 back into the placement block 18, the annular handle 14 is continuously kept in an upright state, so that the annular handle 14 is continuously in the best state for taking, facilitating the repeated use of the annular handle 14, and thus improving the working efficiency of the user.

[0035] Working principle and usage process of the utility model: When in use, after the transformer clamp body 2 is sleeved on the toroidal transformer and the mylar clamp body 3 is sleeved on the mylar, the user holds the auxiliary handle 11 and rotates it, causing the rotating rod 10 to rotate. While the rotating rod 10 rotates, it pulls the first rope 12. The first rope 12 moves along the track on the inner wall of the T-shaped frame 905 and pulls the slider 904 upward. At this time, the slider 904 moves along the track of the chute 903, squeezing the second spring 906, so that the slider 904 no longer limits and fixes the L-shaped hook block 901. Then, the resilience generated when the first spring 8 was previously squeezed by the connecting rod 6 and the support block 7 restores the first spring 8 and pushes the connecting rod 6 to move, causing the transformer clamp body 2 and the mylar clamp body 3 to reset and stably clamp the toroidal transformer and the mylar. Then, the user rotates the knob 5 to rotate the toroidal transformer and the mylar, so that the toroidal transformer winds one circle of mylar. After that, the mylar is cut by the cutting knife 4. When replacing the next toroidal transformer for winding mylar, the user holds the annular handle 14 and pulls it. The second rope 13 moves along the track on the inner wall of the support block 7. At the same time, the second rope 13 pulls the connecting rod 6, causing the first spring 8 to be squeezed. During this process, the L-shaped hook block 901 moves together. When the L-shaped hook block 901 moves to a certain position, the inclined surface on the right side of the L-shaped hook block 901 contacts the slider 904 on the main body frame 902. At this time, when continuing to move, the slider 904 is affected by the extrusion of the inclined surface of the L-shaped hook block 901 and moves upward along the track of the chute 903. At the same time, the second spring 906 generates a resilience force due to the extrusion between the slider 904 and the T-shaped frame 905. After the inclined surface of the L-shaped hook block 901 completely passes through the slider 904, the resilience force of the second spring 906 restores the second spring 906 and pushes the slider 904 to reset. At this time, the L-shaped hook block 901 will be limited and fixed by the slider 904, so that the transformer clamp body 2 is kept in an open state to replace the toroidal transformer, thus having the advantage of assisting in mylar winding.

[0036] To sum up: For the clamp for producing transformers, by setting the connecting rod 6 and the first spring 8, after the transformer clamp body 2 is sleeved on the toroidal transformer and the mylar clamp body 3 is sleeved on the mylar, the resilience force generated by the first spring 8 previously squeezed by the connecting rod 6 and the support block 7 restores the first spring 8 and pushes the connection, so that the transformer clamp body 2 and the mylar clamp body 3 stably clamp the toroidal transformer and the mylar, solving the problem that neither the mylar clamp nor the transformer clamp has a stable clamping structure, resulting in the mylar and the toroidal transformer shaking when rotating the knob for winding whether the mylar is sleeved on the mylar clamp body or the transformer is sleeved on the transformer clamp body, thus causing the rubber ring to be pasted crookedly, and achieving the effect of assisting in mylar winding.
