Description
Technical Field
[0001] This utility model relates to the field of automation technology, and in particular to an automatic oil supply device for in-mold tapping of a TV module backplate. Background Technology
[0002] In the television manufacturing industry, the backplate of a television module is a key structural component supporting core parts such as the screen and circuit board. Its processing quality directly affects the assembly accuracy and reliability of the entire machine. Numerous threaded holes need to be machined on the backplate to secure components. In-mold tapping technology integrates the tapping process into the stamping die, achieving integrated "stamping-tapping" production, significantly improving efficiency and precision. However, the intense friction between the cutting tool and the metal sheet during tapping generates high temperatures and debris, requiring an automatic oil supply device for lubrication and cooling to ensure processing quality and tool life.
[0003] Traditional automatic oil supply devices for tapping in the backplate of television modules mostly adopt a fixed oil spraying structure. They deliver lubricating oil to the nozzles through a simple oil pump and pipeline, relying on a preset oil path layout to lubricate the tapped parts. Such devices usually fix the nozzles on the mold frame, and the spray direction and angle are determined during equipment assembly, making it difficult to adjust the oil spray path according to changes in backplate specifications or tapping positions.
[0004] However, with the diversification of TV backplate sizes and the increasing complexity of hole layouts, traditional fixed-angle oil spraying structures are ill-suited to the tapping requirements of different backplate models, often resulting in oil spraying deviating from the tapping point. This leads to insufficient tool lubrication, accelerated wear, and high temperatures caused by localized lubrication deficiencies, resulting in decreased thread machining accuracy, deteriorated surface quality, increased defect rates and tool replacement costs, and ultimately hindering improvements in production efficiency and product quality. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an automatic oil supply device for in-mold tapping of TV module backplate, which aims to improve the problem that traditional devices are difficult to adapt to the tapping positions of backplates of different specifications and the direction of lubricating oil injection.

A connecting column is slidably connected to the inner wall of the clamping foot. A limiting groove is opened on the outer wall of the connecting column. A tap is fixedly connected to the lower surface of the connecting column.
[0009] Furthermore, the limiting blocks are fixedly connected to the inner wall of the clamping foot in a ring array, and the clamping foot is used to drive the limiting blocks to move.
[0010] Furthermore, the outer wall of the limiting block is slidably connected inside the limiting groove, and the limiting block is used to fix the connecting column.
[0011] Furthermore, the outer wall of the L-shaped fixing rod is slidably connected inside the L-shaped fixing groove, and the L-shaped fixing rod is used to fix the tightening ring.

At the same time, it ensures that the tap is stable and does not loosen during the tapping process, guaranteeing tapping accuracy and stability. Attached Figure Description

[0027] The adjustment assembly includes a rotating gear 18, which is fixedly connected to the connecting pipe 20. By engaging and disengaging with the limiting gear 19, the angle of the fuel injection pipe 13 is locked and adjusted. The limiting gear 19 is fixedly connected to the lower side of the inner wall of the support cylinder 14. It is fixed to the lower side of the inner wall of the support cylinder 14 to limit the rotation of the rotating gear 18 and keep the angle of the fuel injection pipe 13 fixed.

[0028] Specifically, when in use, press the connecting pipe 20, rotate the gear 18 to compress the spring 17 and disengage it from the limiting gear 19, thus releasing the angle restriction. At this time, the connecting pipe 20 can be rotated to drive the rotating gear 18 to adjust to the target angle. After releasing the connecting pipe 20, the spring 17 pushes the rotating gear 18 to reset, so that it re-engages with the limiting gear 19, thereby locking the angle of the fuel injection pipe 13.
[0029] Reference Figures 1-5A replacement component is provided below the support frame 4. The replacement component includes a limiting block 25, which is fixed in a ring array on the inner wall of the clamp foot 21. It cooperates with the limiting groove 26 on the connecting column 9 to realize the positioning and fixing of the connecting column 9. The limiting block 25 is located below the support frame 4. A motor 5 is fixedly connected to the outer wall of the support frame 4. A connecting cylinder 15 is fixedly connected to the output end of the motor 5.

An L-shaped fixing groove 23 is opened on the inner wall of the tightening ring 22. The connecting column 9 is slidably connected to the inner wall of the clamp foot 21. A limiting groove 26 is opened on the outer wall of the connecting column 9. The lower surface of the connecting column 9 A tap 16 is fixedly connected to the surface. Limiting blocks 25 are fixedly connected to the inner wall of the clamping foot 21 in a ring array. The clamping foot 21 is used to drive the limiting blocks 25 to move. The outer wall of the limiting blocks 25 is slidably connected to the inside of the limiting groove 26. The limiting blocks 25 are used to fix the connecting column 9. The outer wall of the L-shaped fixing rod 24 is slidably connected to the inside of the L-shaped fixing groove 23. The L-shaped fixing rod 24 is used to fix the tightening ring 22. One end of the oil supply pipe 6 is fixedly connected to the inside of the oil outlet tank 11. The inner wall of the oil outlet tank 11 is fixedly connected to the outer wall of the support frame 4. The rotating gear 18 is set on the inner wall of the support cylinder 14. One end of the connecting pipe 20 is fixedly connected to the lower surface of the rotating gear 18. The connecting pipe 20 is used to push the rotating gear 18 to disengage from the limiting gear 19. One end of the spring 17 is fixedly connected to the upper surface of the rotating gear 18. The spring 17 is used to push the rotating gear 18 to engage with the limiting gear 19.
[0030] Specifically, rotate the tightening ring 22 to make the L-shaped fixing groove 23 slide along the L-shaped fixing rod 24, releasing the constraint on the locking foot 21. Then, pull out the connecting post 9 downwards to make the limiting groove 26 disengage from the limiting block 25. Remove the old tap 16. When installing the new tap 16, insert its connecting post 9 into the locking foot 21. The limiting block 25 slides into the limiting groove 26 to achieve positioning. Rotate the tightening ring 22 in the opposite direction. The L-shaped fixing groove 23 slides along the L-shaped fixing rod 24 and tightens the locking foot 21 to complete the locking of the new tap 16.
[0031] Working principle: When an automatic oil supply device for tapping the back plate of a TV module is needed, pressing the connecting pipe 20 will rotate the gear 18 to compress the spring 17 and disengage it from the limiting gear 19. At this time, the connecting pipe 20 can be rotated to drive the rotating gear 18 to adjust to the target angle. After releasing the connecting pipe 20, the spring 17 will push the rotating gear 18 to reset, so that it re-engages with the limiting gear 19, thereby locking the angle of the oil injection pipe 13.
[0032] Furthermore, rotating the tightening ring 22 causes the L-shaped fixing groove 23 to slide along the L-shaped fixing rod 24, releasing the constraint on the locking foot 21. Then, the connecting post 9 is pulled out downwards, causing the limiting groove 26 to disengage from the limiting block 25, allowing the old tap 16 to be removed. When installing the new tap 16, its connecting post 9 is inserted into the locking foot 21, and the limiting block 25 slides into the limiting groove 26 to achieve positioning. Rotating the tightening ring 22 in the opposite direction causes the L-shaped fixing groove 23 to slide along the L-shaped fixing rod 24 and tighten the locking foot 21, thus locking the new tap 16.
