Description

Technical Field

[0001] The present invention belongs to the technical field of transformers, and particularly relates to a transformer pressing device. Background Art

[0002] During the manufacturing process of a transformer, the coils of the transformer are generally sleeved on two adhesively bonded magnetic cores. To ensure the tightness and firmness of the bonding of the two magnetic cores, a pressing device is generally used to perform a pressure-holding operation on the two magnetic cores, thereby improving the bonding effect of the glue on the two magnetic cores.

[0003] When the existing pressing device performs a pressing operation on a transformer, in order to improve the pressing efficiency of the transformer, generally multiple transformers are placed at the bottom of the same pressing plate, and then pressure is applied to the pressing plate to simultaneously complete the pressing operation on multiple transformers. However, since the heights of different transformers are different, when pressing multiple transformers, the pressures received by the multiple transformers are different, which in turn affects the overall pressing effect of the transformer and reduces the yield rate of the transformer.

[0004] Therefore, it is very necessary to invent a transformer pressing device to solve the above problems. Summary of the Invention

[0005] In view of the above problems, the present invention provides a transformer pressing device to solve the problems raised in the above background art.

A first pressing spring is sleeved at the position of the positioning rod at the bottom of the pressing plate, and both ends of the first pressing spring are fixedly connected to the bottom of the pressing plate and the top of the pressing block respectively.

[0008] Further, the power assembly includes a pull rod, and the pull rod sequentially horizontally and vertically slides through and is inserted into a plurality of movable blocks. A columnar first gear is fixedly sleeved at the left end of the pull rod. A toothed plate is arranged on the front side of the first gear, and the teeth on the toothed plate are always engaged with the first gear. The toothed plate vertically slides through and is inserted into the operating table, and the top end of the toothed plate is vertically fixedly connected to the bottom of the pressing plate. A fixing block is threadedly sleeved at the end of the pull rod close to the first gear. The other end of the pull rod is movably sleeved with a mounting block, and both the mounting block and the fixing block are fixedly connected to the bottom of the operating table. Limiting rings and stoppers are respectively arranged on both sides of the movable block. The limiting rings and the stoppers are fixedly sleeved on the pull rod, and the limiting rings are closer to the first gear than the stoppers. A second pressing spring is fixedly connected between the movable block and the stopper, and the second pressing spring is sleeved on the pull rod.

[0009] Further, the dial rod is rotatably connected to the top of the movable block. A second gear is sleeved at a position of the dial rod close to the bottom end. Teeth are uniformly arranged on the rear side hole wall of the limiting hole, and the second gear is engaged with the teeth.

[0015] The technical effects and advantages of the present invention:

[0016] 1. In the present invention, by providing a pressing component, during the process of the pressing plate driving multiple pressing blocks to move downward, the pressing blocks can press the transformer under the pressure of the first pressing springs. And since the first pressing springs and pressing blocks on the top of each transformer are independent, each first pressing spring pressing block can be compressed to different degrees according to the different heights of the transformer at its bottom, so as to cooperate with the pressing blocks to achieve separate pressing operations on the transformers and make the multiple transformers maintain the same pressing effect, thereby improving the yield rate of the transformers.

[0017] 2. In the present invention, by providing a lever, after placing the transformer into the inner area of the working station and making the rear side of the transformer contact the baffle, as the electric push rod gradually extends, the toothed plate can drive the pull rod to rotate while also driving the lever to move along the limiting hole towards the transformer. When the lever contacts the transformer, as the lever continues to move, the lever can automatically push the transformer to be close to the partition on the left side of the working station, thus realizing the rapid positioning of the pressing position of the transformer.

[0018] 3. In the present invention, by providing a second gear, when the movable block moves along the limiting groove under the push of the second pressing spring, the second gear can move along the teeth to drive the lever to rotate backward. During this process, when the lever contacts the transformer, in addition to being able to push the transformer to move to the left side of the working station, the rotating lever can also drive the transformer to move backward through friction, so that the transformer can be close to the baffle and the left baffle, thereby ensuring that the pressing block can be directly above the transformer and apply a uniform downward pressure to the transformer, improving the pressure maintaining effect of the pressing block on the transformer.

Detailed implementation manners

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] The present invention provides a transformer pressing device as Figures 1 to 7 shown, which includes an operating table 1. A strip-shaped baffle 2 is fixedly connected to the top of the operating table 1. A plurality of workstations are evenly arranged on the front side of the baffle 2, and a vertical partition 3 is arranged between adjacent two workstations. The rear side of the partition 3 is fixedly connected to the front side of the baffle 2. Through holes matching the width of the workstations are formed through the positions of the baffle 2 facing the plurality of workstations. A transformer 4 is arranged inside the workstations. The same pressing plate 5 is arranged on the tops of the plurality of transformers 4. Pressing components 6 are arranged at the positions of the bottom of the pressing plate 5 facing the plurality of workstations. An electric push rod 7 is vertically and fixedly connected to the top of the pressing plate 5. The top of the electric push rod 7 is fixedly connected to an L-shaped fixing plate 8. The fixing plate 8 is fixedly connected to the top of the operating table 1. Limiting rods 9 are vertically and slidably inserted through both sides of the top of the pressing plate 5. The limiting rods 9 are fixedly connected to the top of the operating table 1. Positioning plates 10 are arranged on one side of the two limiting rods 9 facing each other. The positioning plates 10 are vertically and fixedly connected to the top of the operating table 1. A vertical receiving hole 11 is formed in the partition 3 on the left side of the transformer 4. A lever 12 is arranged in the receiving hole 11. A limiting hole 13 is formed through the position of the top of the operating table 1 facing the lever 12, and the lever 12 is inserted through the limiting hole 13. The bottom end of the lever 12 is connected to a movable block 14, and the movable block 14 is slidably installed at the bottom of the limiting hole 13. A power component 15 is arranged between the plurality of movable blocks 14. The widths of both sides of the pressing plate 5 are smaller than the width of the middle part thereof, and a clamping groove matching the two sides of the pressing plate 5 is formed in the top of the positioning plate 10. The height of the baffle 2 is the same as the height of the transformer 4. The through holes on the baffle 2 are aligned with the wire core parts of the transformer 4, and the opening height of the through holes is greater than the total height of the wire core parts of the transformer 4;

[0029] The pressing component 6 includes a pressing block 61. Two positioning rods 62 are symmetrically and vertically fixedly connected to the top of the pressing block 61. The positioning rods 62 vertically slide through and are inserted into the pressing plate 5. A first pressing spring 63 is sleeved on the positioning rod 62 at the bottom of the pressing plate 5. Two ends of the first pressing spring 63 are respectively fixedly connected to the bottom of the pressing plate 5 and the top of the pressing block 61. The bottom surface size of the pressing block 61 matches the top surface size of the transformer 4, and the left side and the rear side of the pressing block 61 are flush with the partition 3 on the left side of the work station and the front side of the baffle 2 respectively;

[0030] When performing the pressing operation on the transformer 4, the transformers 4 to be pressed are placed one by one inside multiple work stations, and the side where the cores of the transformers 4 are exposed is aligned with the through hole of the baffle 2. Then, the transformer 4 is pushed to make it fit with the baffle 2 and the partition 3 on the left side of the work station, so as to quickly locate the pressing position of the transformer 4. When the transformer 4 is in contact with the baffle 2, the core of the transformer 4 can be located in the through hole, so that it will not come into contact with the baffle 2, thus avoiding deformation or damage of the core part of the transformer 4 due to extrusion or collision;

[0031] Then, start the electric push rod 7 to drive the pressing plate 5 to move downward under the restriction of the limiting rod 9. During this process, as the pressing plate 5 moves downward, the pressing block 61 gradually approaches the top of the transformer 4, and the toggle rod 12 can gradually clamp the transformer 4 from the right side of the transformer 4 under the drive of the power assembly 15, so as to ensure that the transformer 4 can be located directly below the pressing block 61. As the pressing plate 5 continues to move downward, when the bottom of the pressing block 61 contacts the transformer 4, as the pressing plate 5 moves further downward, the pressing block 61 can move downward relative to the pressing plate 5 under the pushing of the transformer 4, so as to compress the first pressing spring 63. When both sides of the pressing plate 5 are completely inserted into the card slots on the top of the positioning plate 10, the electric push rod 7 stops extending, and the pressing block 61 can press the transformer 4 under the pressure of the first pressing spring 63. And because the first pressing springs 63 and the pressing blocks 61 on the top of each transformer 4 are independent, each first pressing spring 63 and the pressing block 61 can be compressed to different degrees according to the different heights of the transformers 4 at their bottoms, so as to cooperate with the pressing block 61 to realize the individual pressing operation on the transformer 4 and make the multiple transformers 4 have the same pressing effect, thus improving the qualified rate of the transformer 4.

[0032] As Figure 2 and Figure 3As shown, the power assembly 15 includes a pull rod 151 which horizontally and vertically slides through and is inserted into a plurality of movable blocks 14 in sequence. A columnar first gear 152 is fixedly sleeved at the left end of the pull rod 151. A toothed plate 153 is arranged on the front side of the first gear 152, and the teeth 17 on the toothed plate 153 are always engaged with the first gear 152. The toothed plate 153 vertically slides through and is inserted into the operating table 1, and the top end of the toothed plate 153 is vertically and fixedly connected to the bottom of the pressing plate 5. A fixing block 154 is threadedly sleeved at one end of the pull rod 151 close to the first gear 152. The other end of the pull rod 151 is movably sleeved with a mounting block 155, and both the mounting block 155 and the fixing block 154 are fixedly connected to the bottom of the operating table 1. Limit rings 156 and stoppers 157 are respectively arranged on both sides of the movable block 14. Both the limit rings 156 and the stoppers 157 are fixedly sleeved on the pull rod 151, and the limit rings 156 are closer to the first gear 152 than the stoppers 157. A second compression spring 158 is fixedly connected between the movable block 14 and the stopper 157, and the second compression spring 158 is sleeved on the pull rod 151;

[0033] When the transformer 4 is placed in the inner area of the work station, in order to improve the placement efficiency of the transformer 4, after the transformer 4 is placed on the top of the operating table 1, the transformer 4 can be pushed backward to make it contact with the baffle 2. As the electric push rod 7 gradually extends, the pressing plate 5 can drive the toothed plate 153 to move downward under the action of the electric push rod 7. As the toothed plate 153 moves downward, the toothed plate 153 can drive the pull rod 151 to rotate through the cooperation with the first gear 152. As the pull rod 151 rotates, the pull rod 151 can cooperate with the fixing block 154 to move in the direction close to the first gear 152. As the pull rod 151 moves, the stopper 157 on the pull rod 151 can drive the movable block 14 and the dial rod 12 to move out of the storage hole 11 and move along the limit hole 13 in the direction of the transformer 4 through the thrust on the second compression spring 158. When the dial rod 12 contacts the transformer 4, as the dial rod 12 continues to move, the dial rod 12 can automatically push the transformer 4 to be closely attached to the partition plate 3 on the left side of the work station, so as to automatically realize the rapid positioning of the pressing position of the transformer 4;

[0034] When the transformer 4 is completely attached to the partition plate 3 on the left side of the work station, as the pull rod 151 continues to move, the baffle 2 can gradually squeeze the second compression spring 158, and the dial rod 12 can be closely attached to the transformer 4 under the squeezing action of the second compression spring 158 on the movable block 14, so as to ensure the accuracy of the pressing position of the transformer 4, and further ensure that the pressing block 61 can uniformly apply pressure to the top of the transformer 4 in the subsequent process, ensuring the pressing effect of the transformer 4. During the compression process of the second compression spring 158, the pressing block 61 also gradually moves downward and presses against the top of the transformer 4, thereby realizing the pressure maintaining operation on the transformer 4.

[0035] As Figure 5 and Figure 7 shown, the lever 12 is rotatably connected to the top of the movable block 14. A second gear 16 is sleeved at a position near the bottom end of the lever 12. Teeth 17 are uniformly arranged on the rear side wall of the limiting hole 13, and the second gear 16 meshes with the teeth 17. The height of the lever 12 above the operating table 1 is greater than half of the height of the transformer 4, and multiple vertical anti-slip lines are uniformly arranged on the surface of the lever 12;

[0036] When the transformer 4 is placed in the inner area of the station and is pushed backward along the top of the operating table 1 towards the baffle 2, due to different thrusts, the transformer 4 may not be able to keep in contact with the baffle 2, resulting in the pressing block 61 being unable to apply a uniform downward pressure on the transformer 4. At this time, with the second gear 16 provided, when the movable block 14 moves along the limiting groove under the push of the second compression spring 158, the second gear 16 can move along the teeth 17, driving the lever 12 to rotate backward. During this process, when the lever 12 contacts the transformer 4, in addition to being able to push the transformer 4 to move to the left side of the station, the rotating lever 12 can also drive the transformer 4 to move backward through friction, so that the transformer 4 can be in close contact with the baffle 2 and the left baffle 2, ensuring that the pressing block 61 is directly above the transformer 4 and applying a uniform downward pressure on the transformer 4, improving the pressure maintaining effect of the pressing block 61 on the transformer 4.

[0037] As Figure 1 , Figure 4 and Figure 5 shown, a plurality of rollers 18 are uniformly installed in the area on the top surface of the operating table 1 opposite to the transformer 4. The rollers 18 are flush with the front side of the operating table 1, and the top of the rollers 18 is higher than the top of the operating table 1;

[0038] With the rollers 18 provided, when the transformer 4 is placed on the operating table 1, the transformer 4 can be supported by the plurality of rollers 18. When the lever 12 contacts the transformer 4 driven by the movable block 14, as the lever 12 rotates, the lever 12 can push the transformer 4 backward through friction, so that the transformer 4 can be in close contact with the baffle 2 and the left partition 3. During the process of the transformer 4 moving along the top of the operating table 1, the rollers 18 can reduce the frictional force between the bottom of the transformer 4 and the top of the operating table 1, making the movement of the transformer 4 smoother.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, not to limit it.
