Description

Technical Field

[0001] This utility model relates to the field of drilling tooling technology, specifically a flip-type drilling tooling. Background Technology

[0002] During the drilling process, tooling is needed to hold the workpiece and keep it stable. To facilitate drilling, existing tooling can generally automatically flip the workpiece during use.

[0003] The tooling still exhibits some problems during its use. During the tooling's repeated flipping, its internal components are constantly subjected to friction. Prolonged friction accelerates the wear of the tooling. At this point, workers need to regularly add lubricating oil to the connection points. However, since the connection points are in close contact, adding lubricating oil is very inconvenient and also wastes lubricating oil.

[0004] Therefore, those skilled in the art have provided a flip-type drilling tool to solve the problems mentioned in the background art. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, the present invention provides a flip-type drilling fixture. By setting a moving mechanism, lubricating oil can be directly added to the rotating connection of the fixture, which can reduce wear between fixture parts and effectively increase the service life of the fixture. At the same time, it eliminates the need for workers to manually add lubricating oil from the outside, saving time and effort, and also avoiding the waste of lubricating oil. Furthermore, by setting a rotating mechanism, the lubricating oil can be automatically stirred during the process of adding lubricating oil, which is very convenient and avoids the impact of prolonged standing of lubricating oil on the lubrication effect, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A flip-type drilling fixture includes a drilling template, with a fixture clamp fixedly connected to the upper end of the drilling template and a connecting rod fixedly connected to the lower end of the drilling template.

[0021] Please see Figures 1-5 In this embodiment of the utility model, a flip-type drilling fixture includes a drilling template 1, which is directly mounted on a support. A fixture 4 is fixedly connected to the upper end of the drilling template 1. The fixture 4 is used to clamp the workpiece for easy drilling. A connecting rod 5 is fixedly connected to the lower end of the drilling template 1. The device can be mounted on the support through the connecting rod 5. By rotating the connecting rod 5 based on the support, the drilling template and the fixture 4 can be flipped 180 degrees, which facilitates drilling the workpiece again.

[0022] The drilling template 1 has a circular groove 7, and a movable column 8 is slidably connected inside the circular groove 7. The movable column 8 is hollow and is used to hold lubricating oil. An injection hole 6 is provided at the upper end of the movable column 8, through which lubricating oil can be added to the interior of the movable column 8. A first drop hole 18 is provided at the lower end of the movable column 8. A closing plate 19 is connected to the lower end of the movable column 8 through a spring column (not shown in the figure), through which the first drop hole 18 can be closed. An arc plate 20 is connected inside the drilling template 1. The arc plate 20 contacts the connecting rod 5. A second drop hole 21 is provided on the arc plate 20. The lubricating oil inside the movable column 8 falls directly onto the connecting rod 5 through the first drop hole 18 and the second drop hole 21, lubricating the connection between the rod 5 and the support and preventing accelerated wear at the connection due to repeated rotation.

[0023] The drill template 1 has a groove 22 inside, and a cylinder 23 is fixedly connected inside the groove 22. A movable strip 24 and a spring 25 are fitted on the cylinder 23. The movable strip 24 is connected to the movable column 8. When the movable column 8 moves, it will drive the movable strip 24 to move and squeeze the spring 25. When the movable column 8 is not squeezed by external force, it can return to its original position under the action of the spring 25, and the addition of lubricating oil will stop.

[0024] A reciprocating screw 9 is rotatably connected inside the moving column 8. The upper end of the reciprocating screw 9 extends through to the outside of the moving column 8 and is fixedly connected to a disc 10. A fixed disc 11 is rotatably connected to the center of the upper end of the disc 10. A connecting ring 14 is connected to the reciprocating screw 9 through a threaded sleeve. A cleaning ring 16 is connected to the connecting ring 14 through multiple stirring rods 15. The cleaning ring 16 is in full contact with the inner wall of the moving column 8. A limiting rod is set between the cleaning ring 16 and the moving column 8 so that it can only move up and down along the moving column 8.

[0025] A slider 12 is fixedly connected to the outer wall of the disc 10. A spiral groove 13 is provided on the drill template 1. The disc 10 is moved downward by the fixed plate 11. When the disc 10 enters the interior of the drill template 1, the slider 12 moves along the spiral groove 13, thereby driving the disc 10 and the reciprocating screw 9 to rotate. When the reciprocating screw 9 rotates, it can drive the stirring rod 15 and the cleaning ring 16 to move up and down through the connecting ring 14, thereby stirring the lubricating oil inside the moving column 8 and cleaning its inner wall. The lower end of the stirring rod 15 is fixedly connected to the top rod 17. When the top rod 17 moves into the interior of the first drop hole 18, it pushes the closing plate 19 to move and open the first drop hole 18.

[0026] The working principle of this utility model is as follows: When the device is needed, it is first installed at a designated position on the tooling bracket via the connecting rod 5. The connecting rod 5 rotates on the bracket, thereby achieving the flipping of the workpiece. The connection between the connecting rod 5 and the bracket will wear down due to long-term back-and-forth rotation, requiring periodic lubrication. To lubricate the connection, the fixed plate 11 and the disc 10 are moved downwards, and the moving column 8 moves into the circular groove 7. When the disc 10 moves into the circular groove 7, the slider 12 enters the spiral groove 13. As the slider 12 moves within the spiral groove 13, it drives the disc 10... The reciprocating screw 9 rotates, and when the reciprocating screw 9 rotates, it will drive the stirring rod 15 and the cleaning ring 16 to move downward through the connecting ring 14, thereby stirring the lubricating oil inside the moving column 8. When the stirring rod 15 moves to the bottom, the top rod 17 enters the first drop hole 18 and pushes the sealing plate 19 to move downward, thereby opening the first drop hole 18. The lubricating oil inside the moving column 8 flows out and falls onto the connecting rod 5 through the second drop hole 21, thereby lubricating the connection and reducing wear. When the moving column 8 moves, it will also drive the moving strip 24 to move and squeeze the spring 25. When the moving column 8 is not squeezed by external force, it can return to its original position under the action of the spring 25.

[0027] 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.
