Description

Technical Field

[0001] This utility model belongs to the technical field of transformer production equipment, specifically a fixed tooling for producing small transformers for household appliances. Background Technology

[0002] A small transformer for household appliances is a small electromagnetic induction device used in household appliances to change AC voltage or current. Its core function is to achieve voltage transformation through the turns ratio of the primary coil (input end) and the secondary coil (output end) based on the principle of electromagnetic induction, so as to meet the power supply needs of different electrical components. Its main structure includes an iron core, coils, insulating materials and shell.

[0003] When manufacturing small transformers for home appliances, holes need to be drilled in the casing to facilitate final assembly. Therefore, appropriate fixing fixtures are required to secure the casing. However, existing fixing fixtures still have shortcomings in actual use. Most existing fixing fixtures use fixed clamps to clamp the casing. When drilling holes in symmetrical positions on the front and back of the casing, operators need to repeatedly disassemble and reassemble the clamps to adjust the orientation and position of the casing, which increases the processing time and reduces processing efficiency. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems. This invention provides a fixing fixture for producing small transformers for household appliances, which has the advantage of facilitating the adjustment of the housing orientation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed fixture for producing small transformers for household appliances, comprising a base, with support plates fixedly installed on the left and right sides of the bottom end of the base, mounting holes respectively opened on the front and rear sides of the top end of the support plates, a turntable movably sleeved at the center of the top end of the base, a placement platform movably sleeved on the top of the inner surface of the turntable, a connecting rod fixedly installed at the center of the bottom end of the turntable, the bottom end of the connecting rod penetrating the base and extending to the outside of the base and fixedly sleeved with a driven gear, the top end of the driven gear being movably connected to the bottom end of the base, a fixing frame fixedly installed on the right side of the bottom end of the base, a servo motor fixedly installed at the center of the bottom of the inner surface of the fixing frame, a rotating shaft fixedly sleeved at the other end of the output shaft of the servo motor, a driving gear fixedly sleeved on the outer surface of the rotating shaft, the top end of the driving gear being movably connected to the bottom end of the base, and the outer surface of the driving gear meshing with the outer surface of the driven gear.

[0006] As a preferred embodiment of this utility model, clamps are movably connected to the left and right sides of the top center of the base, and there are two clamps. Fixing blocks are movably connected to the opposite sides of the two clamps, and there are two fixing blocks. The bottom ends of the two fixing blocks are fixedly connected to the top of the base.

[0007] As a preferred embodiment of this utility model, pneumatic cylinders are fixedly installed on the middle part of the opposite sides of the two fixed blocks, and the other end of the pneumatic cylinder passes through the fixed block and extends to the outside of the fixed block and is fixedly connected to the outer surface of the clamp.

[0008] As a preferred embodiment of this utility model, the left and right sides of the inner surface of the turntable are respectively provided with sliding grooves, and the top of the sliding groove is movably sleeved with a slider, and the outer surface of the slider is fixedly connected to the outer surface of the placement platform.

[0009] As a preferred embodiment of this utility model, a circular plate is movably sleeved at the middle of the bottom of the inner surface of the turntable, and a spring is fixedly installed at the middle of the top of the circular plate, with the other end of the spring fixedly connected to the bottom of the placement platform.

[0010] As a preferred embodiment of this utility model, a limiting rod is fixedly installed at the middle of the bottom end of the circular plate. The bottom end of the limiting rod passes through the turntable and the connecting rod and extends into the interior of the connecting rod, and a block is fixedly installed thereon. The outer surface of the block and the bottom of the inner surface of the connecting rod are movably connected.

[0011] As a preferred embodiment of this utility model, a threaded rod is movably sleeved inside the block. The bottom end of the threaded rod passes through the block and the connecting rod and extends to the outside of the connecting rod, and a handle is fixedly sleeved thereon. The outer surface of the threaded rod and the inner surface of the bottom end of the connecting rod are threaded together.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a turntable, a placement platform, a connecting rod, a driven gear, and a driving gear, will cause the rotating shaft to drive the driving gear to rotate when the servo motor is started. Since the outer surfaces of the driving gear and the driven gear are meshed, the driven gear will rotate around the connecting rod as the axis, thereby causing the turntable and placement platform to rotate together with the driven gear through the connecting rod. In this way, the position of the small transformer shell for household appliances can be adjusted through the mutual cooperation of the connecting rod, the driven gear, and the driving gear, thereby improving the convenience of using the fixed tooling and the processing efficiency of the small transformer shell for household appliances.

[0014] 2. This utility model, by setting up a circular plate, spring, limiting rod, and square block, allows the placement platform to move downwards after contact with the placement platform when the drill bit drills into the casing of a small household appliance transformer. This is because the placement platform is movably fitted onto the inner surface of the turntable. At this time, the placement platform will move along the inner surface of the turntable and compress the spring, thus ensuring that the drill bit can completely penetrate the casing. In addition, by turning the handle, the square block can move upwards along with the limiting rod and the circular plate under the action of the threaded rod, thereby adjusting the spring force and improving the load-bearing capacity of the placement platform.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6As shown, this utility model provides a fixed fixture for producing small transformers for household appliances, including a base 1. Support plates 2 are fixedly installed on the left and right sides of the bottom end of the base 1. Mounting holes 3 are opened on the front and rear sides of the top end of the support plates 2. A turntable 4 is movably sleeved at the middle of the top end of the base 1. A placement platform 5 is movably sleeved on the top of the inner surface of the turntable 4. A connecting rod 6 is fixedly installed at the middle of the bottom end of the turntable 4. The bottom end of the connecting rod 6 passes through the base 1 and extends to the outside of the base 1 and is fixedly sleeved with a driven gear 7. The top end of the driven gear 7 is movably connected to the bottom end of the base 1. A fixing frame 8 is fixedly installed on the right side of the bottom end of the base 1. A servo motor 9 is fixedly installed at the middle of the bottom of the inner surface of the fixing frame 8. A rotating shaft 10 is fixedly sleeved at the other end of the output shaft of the servo motor 9. A driving gear 11 is fixedly sleeved on the outer surface of the rotating shaft 10. The top end of the driving gear 11 is movably connected to the bottom end of the base 1. The outer surface of the driving gear 11 meshes with the outer surface of the driven gear 7.

[0024] When the servo motor 9 is started, the rotating shaft 10 will drive the drive gear 11 to rotate. Since the drive gear 11 and the driven gear 7 mesh with each other, as the drive gear 11 rotates, the driven gear 7 will drive the turntable 4 and the placement platform 5 to rotate around the connecting rod 6 through the connecting rod 6. In this way, the position of the small transformer shell of the household appliance placed on the top of the placement platform 5 can be adjusted by the cooperation of the driven gear 7 and the drive gear 11, thereby improving the convenience of using the fixed tooling.

[0025] Among them, clamps 12 are movably connected to the left and right sides of the top center of the base 1, and there are two clamps 12. Fixing blocks 13 are movably connected to the opposite sides of the two clamps 12, and there are two fixing blocks 13. The bottom ends of the two fixing blocks 13 are fixedly connected to the top of the base 1.

[0026] The clamp 12 is used to clamp and fix the shell of the small transformer for household appliances, while the fixing block 13 serves to support and fix it.

[0027] Among them, pneumatic cylinders 14 are fixedly installed on the middle part of the back side of the two fixing blocks 13 respectively. The other end of the pneumatic cylinder 14 passes through the fixing block 13 and extends to the outside of the fixing block 13 and is fixedly connected to the outer surface of the clamp 12.

[0028] The two pneumatic cylinders 14 are of the same model and size, thus ensuring that the two pneumatic cylinders 14 generate the same thrust on the clamp 12.

[0029] Among them, the left and right sides of the inner surface of the turntable 4 are respectively provided with sliding grooves 15, and the top of the sliding groove 15 is movably sleeved with a slider 16, and the outer surface of the slider 16 is fixedly connected to the outer surface of the placement platform 5.

[0030] The cooperation between the slide 15 and the slider 16 will restrict the movement of the placement platform 5, thereby ensuring the stability of the movement of the placement platform 5. At the same time, the slide 15 and the slider 16 can also ensure that the placement platform 5 and the turntable 4 can rotate together.

[0031] Among them, a circular plate 17 is movably sleeved at the middle of the bottom of the inner surface of the turntable 4, and a spring 18 is fixedly installed at the middle of the top of the circular plate 17. The other end of the spring 18 is fixedly connected to the bottom of the placement platform 5.

[0032] When the placement platform 5 is squeezed, it will move along the inner surface of the turntable 4 and compress the spring 18. Under the restoring action of the spring 18, the placement platform 5 will be forced to return to its original position.

[0033] Among them, a limiting rod 19 is fixedly installed in the middle of the bottom end of the circular plate 17. The bottom end of the limiting rod 19 passes through the turntable 4 and the connecting rod 6 and extends into the interior of the connecting rod 6, and a block 20 is fixedly installed thereon. The outer surface of the block 20 and the bottom of the inner surface of the connecting rod 6 are movably connected.

[0034] When block 20 moves along the inner surface of connecting rod 6, it will move along with circular plate 17 through limiting rod 19, thereby increasing the elastic force of spring 18 by compressing spring 18.

[0035] The block 20 is internally fitted with a threaded rod 21. The bottom end of the threaded rod 21 passes through the block 20 and the connecting rod 6 and extends to the outside of the connecting rod 6, and is fixedly fitted with a handle 22. The outer surface of the threaded rod 21 and the inner surface of the bottom end of the connecting rod 6 are threaded together.

[0036] When the handle 22 is turned, the threaded rod 21 will rotate along the inner surface of the block 20. Since the threaded rod 21 and the bottom end of the connecting rod 6 are threaded together, the block 20 will move under the action of the threaded rod 21.

[0037] Working principle and usage process of this utility model:

[0038] In use, the operator first installs the fixing fixture in the designated position through the mounting hole 3. Then, the operator places the small transformer shell of the appliance in the center of the placement platform 5. At this time, the pneumatic cylinder 14 is activated, and the clamp 12 moves towards the placement platform 5 to clamp and fix the small transformer shell of the appliance. Then, drilling can begin. When it is necessary to drill holes at symmetrical positions of the small transformer shell of the appliance, the operator activates the pneumatic cylinder 14 to reset the clamp 12, and then activates the servo motor 9, which causes the rotating shaft 10 to drive the drive gear 11 to rotate. This causes the driven gear 7, which meshes with the drive gear 11, to rotate together with the turntable 4 and the placement platform 5 through the connecting rod 6, thereby completing the adjustment of the orientation of the small transformer shell of the appliance. After the adjustment is completed, the operator activates the pneumatic cylinder 14 again and re-clamps the small transformer shell of the appliance through the clamp 12. Finally, drilling can be performed at symmetrical positions.

[0039] During the drilling process, since the placement platform 5 is movably sleeved inside the turntable 4, when the drill bit contacts the placement platform 5, it can squeeze the placement platform 5 and continue to move downward, thus ensuring that the drill bit can completely penetrate the shell of the small household appliance transformer. As the placement platform 5 moves, the placement platform 5 will compress the spring 18. After the drilling is completed, the placement platform 5 will return to its original position under the restoring action of the spring 18. At the same time, if the elastic force of the spring 18 is too small and the shell of the small household appliance transformer sinks too much, the operator turns the handle 22, causing the threaded rod 21, which is threadedly sleeved with the connecting rod 6, to rotate along the inner surface of the block 20. At this time, the block 20 will move upward with the limit rod 19 and the circular plate 17 under the action of the threaded rod 21, compressing the spring 18, thereby increasing the elastic force of the spring 18 and improving the load-bearing capacity of the placement platform 5.
