Description

Technical Field

[0001] This utility model relates to the field of transformer surface polishing technology, and in particular to a surface polishing device for transformer production. Background Technology

[0002] Distribution transformers are one of the important pieces of equipment in the power supply and distribution systems of industrial and mining enterprises and civil buildings. A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation and voltage stabilization. When producing transformer parts, a surface grinding device is needed to grind the transformer to the required specifications to facilitate its use and assembly.

[0003] A search revealed that patent (application number: 202020629000.9) discloses "a surface polishing device for transformer production with dust removal function." This device is used in conjunction with a polishing device, transmission box, motor, screw, transmission block, movable plate, slider, slide rod, transmission rod, exhaust fan, pipe, collection box, and auxiliary mechanism. The exhaust fan cleans the metal shavings on the surface of the polishing device, thereby expanding the cleaning area. This solves the problem that most existing polishing devices on the market do not have a dust removal mechanism. When polishing transformer parts, a large amount of metal shavings are generated, which fall onto the surface of the polishing device, causing pollution to the surrounding environment and harming users over time, thus reducing the practicality of the polishing device.

[0004] However, during the use of the above-mentioned device, since the transformer is usually large in size and the influence range of the wind-powered dust suction is limited, when the grinding gun moves and grinds on the surface of the transformer, the exhaust fan cannot effectively suck up the generated debris. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a surface grinding device for transformer production, which overcomes the deficiencies of existing technologies and effectively solves the problem that the influence range of wind-powered dust suction is limited, and the exhaust fan cannot effectively suck up the generated debris when the grinding gun moves and grinds on the transformer surface.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A surface polishing device for transformer production includes a placement platform. Support plates are welded and fixed to both ends of the top of the placement platform. Symmetrically distributed sliding rods are welded and fixed to the outer walls of opposite sides of the two support plates. A polishing mechanism is slidably connected to the walls of the two sliding rods. The polishing mechanism includes a slider, a fixed frame welded and fixed to the outer wall of one end of the slider, fixed rods welded and fixed to the inner walls of both ends of the fixed frame, a T-shaped plate slidably connected to the wall of the fixed rods, connecting rods welded and fixed to both ends of the outer wall of one side of the T-shaped plate, a fixed plate welded and fixed to one end of the connecting rods, a dust removal assembly slidably connected to the walls of the two connecting rods, and a polishing gun inserted into the dust removal assembly. The dust removal assembly includes a fixed frame, fixed pipes inserted and fixed to both ends of the top of the fixed frame, a dust suction hood inserted and fixed to the bottom of the fixed pipes, a connecting hose inserted and fixed to the top of the fixed pipes, an air inlet pipe inserted and fixed to the top of the connecting hose, and a dust collection box inserted and fixed between the two air inlet pipes.

[0008] By holding the top of the outer wall of the grinding gun and pressing it down, the fixing frame moves the T-shaped plate down along the fixing rod via the connecting rod, bringing the grinding gun close to the transformer shell placed on the top of the platform for grinding. The fixing frame can slide along the connecting rod, and the slider can slide along the sliding rod, allowing the grinding gun to move freely to grind the transformer shell. Since the two dust hoods are always kept on both sides of the grinding gun through the fixing frame and fixing tube, the debris and dust generated during the grinding process can be sucked into the dust collection box without the dust collection power weakening due to the free movement of the grinding gun.

[0009] Preferably, the outer wall of one side of the slider has symmetrically distributed through holes, and the through holes form a sliding fit with the slider rod.

[0010] The slider slides freely on the slide rod through the through hole.

[0011] Preferably, the wall of the fixed rod is fitted with a telescopic spring, and the telescopic spring is located between the bottom of the T-shaped plate and the bottom of the fixed frame.

[0012] The T-shaped plate is lifted upwards by the elasticity of the telescopic spring without external force.

[0013] Preferably, the top center of the fixing frame has an insertion hole, and the insertion hole is connected to the grinding gun. A limit ring is fixedly fitted on the outer wall of the grinding gun, and the outer diameter of the limit ring is larger than the inner diameter of the insertion hole of the fixing frame.

[0014] By connecting the grinding gun to the mounting bracket, when the grinding gun is held and pressed down, the mounting bracket moves downward through the limiting ring.

[0015] Preferably, the outer wall of one side of the fixing frame is provided with connecting holes at both ends, and the connecting holes and the connecting rods are in sliding fit.

[0016] The mounting bracket slides freely on the connecting rod through the connecting holes.

[0017] Preferably, a dust collection box is placed inside the dust collection box, and a cover plate is placed on top of the dust collection box. An air outlet pipe is inserted and fixed to the top of the cover plate, and an air extractor placed on top of the cover plate is inserted into the top of the air outlet pipe.

[0018] The air extraction machine draws air from the dust collection box through the exhaust pipe. The negative pressure formed in the dust collection box draws out the debris and dust generated by the grinding gun through the air inlet pipe, connecting hose, fixed pipe and dust hood.

[0019] Preferably, a filter frame is welded and fixed to the bottom of the cover plate, and a filter screen is welded and fixed to the bottom of the inner wall of the filter frame. The specifications of the outer wall of the filter frame are compatible with the specifications of the inner wall of the dust collection box.

[0020] The cover plate is fixed to the top of the dust collection box by inserting it through the filter frame, and the filter screen filters out the debris and dust in the air.

[0021] The beneficial effects of this utility model are as follows:

[0022] By holding the top of the outer wall of the grinding gun and pressing it down, the fixed bracket can slide along the connecting rod, and the slider can slide along the sliding rod, allowing the grinding gun to move freely to grind the transformer shell. Since the two dust suction hoods are always kept on both sides of the grinding gun through the fixed bracket and fixed tube, the debris and dust generated during the grinding process can be sucked into the dust collection box without the dust strength weakening due to the free movement of the grinding gun. This effectively solves the problem in the existing technology where the influence range of wind-powered dust suction is limited, and the exhaust fan cannot effectively suck up the generated debris when the grinding gun is moving and grinding on the transformer surface.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example:

[0030] Reference Figure 1-4 A surface polishing device for transformer production includes a placement platform 1. Support plates 2 are welded and fixed to both ends of the top of the placement platform 1. Sliding rods 3 are symmetrically distributed and welded and fixed to the outer walls of opposite sides of the two support plates 2. A polishing mechanism 4 is slidably connected to the rod walls of the two sliding rods 3. The polishing mechanism 4 includes a slider 5, a fixing frame 6 welded and fixed to the outer wall of one end of the slider 5, fixing rods 7 welded and fixed to the inner walls of both ends of the fixing frame 6, a T-shaped plate 9 slidably connected to the rod wall of the fixing rod 7, connecting rods 10 welded and fixed to both ends of the outer wall of one side of the T-shaped plate 9, a fixing plate 11 welded and fixed to one end of the connecting rod 10, a dust removal assembly 12 slidably connected to the rod walls of the two connecting rods 10, and a polishing gun 13 inserted into the dust removal assembly 12.

[0031] The dust removal assembly 12 includes a fixed frame 14, a fixed tube 15 inserted and fixed to both ends of the top of the fixed frame 14, a dust suction hood 16 inserted and fixed to the bottom of the fixed tube 15, a connecting hose 17 inserted and fixed to the top of the fixed tube 15, an air inlet pipe 18 inserted and fixed to the top of the connecting hose 17, and a dust collection box 19 inserted and fixed between the two air inlet pipes 18. The outer wall of one side of the slider 5 has symmetrically distributed through holes, which form a sliding fit with the slide rod 3. The slider 5 slides freely on the slide rod 3 through the through holes. The wall of the fixed rod 7 is fitted with a movable telescopic spring 8. The telescopic spring 8 is located between the bottom of the T-shaped plate 9 and the bottom of the fixed frame 6. The elasticity of the telescopic spring 8 can push the T-shaped plate 9 upward without external force.

[0032] A socket is provided at the center of the top of the fixed frame 14. The socket is inserted into the grinding gun 13. A limit ring is fixedly fitted on the outer wall of the grinding gun 13. The outer diameter of the limit ring is larger than the inner diameter of the socket of the fixed frame 14. When the grinding gun 13 is inserted into the fixed frame 14 and the grinding gun 13 is held and pressed down, the fixed frame 14 moves downward through the limit ring. Both ends of the outer wall of one side of the fixed frame 14 are provided with connecting holes. The connecting holes are slidably fitted with the connecting rod 10. The fixed frame 14 slides freely on the connecting rod 10 through the connecting holes.

[0033] A dust collection box 20 is placed inside the dust collection box 19. A cover plate 21 is placed on top of the dust collection box 19. An air outlet pipe 23 is inserted and fixed to the top of the cover plate 21. An air extractor 24 is inserted and placed on top of the cover plate 21 at the top of the air outlet pipe 23. The air extractor 24 sucks the dust inside the dust collection box 19 through the air outlet pipe 23. The negative pressure formed inside the dust collection box 19 sucks the debris and dust generated by the grinding gun 13 through the air inlet pipe 18, connecting hose 17, fixing pipe 16 and dust suction hood 16. A filter frame 22 is welded and fixed to the bottom of the cover plate 21. A filter screen is welded and fixed to the bottom of the inner wall of the filter frame 22. The specifications of the outer wall of the filter frame 22 are adapted to the specifications of the inner wall of the dust collection box 19. The cover plate 21 is inserted and fixed to the top of the dust collection box 19 through the filter frame 22, and the debris and dust in the air are filtered through the filter screen.

[0034] Working principle:

[0035] During operation, by holding the top of the outer wall of the grinding gun 13 and pressing it downwards, the fixed frame 14 drives the T-shaped plate 9 to move downwards along the fixed rod 7 via the connecting rod 10, so that the grinding gun 13 is close to the transformer shell placed on the top of the placement table 1 for grinding. The fixed frame 14 can slide along the connecting rod 10, and the slider 5 can slide along the sliding rod 3, so that the grinding gun 13 can move freely to grind the transformer shell. Since the two dust suction hoods 16 are always kept on both sides of the grinding gun 13 through the fixed frame 14 and the fixed tube 15, the debris and dust generated during the grinding process can be sucked into the dust collection box 20, and the suction power will not be weakened due to the free movement of the grinding gun 13.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
