Description

Technical Field

[0001] This utility model relates to a drilling device for automotive oil line bend flanges. Background Technology

[0002] Automotive oil circuit elbow flanges are key metal fittings used to connect and seal elbow components in automotive oil circuit systems. They belong to a type of pipe connector, and their core function is to achieve a sealed connection between two sections of pipe or equipment through bolt tightening, ensuring stable fluid transmission under high pressure or high temperature environments while preventing leakage. Most elbow flanges currently on the market are made of metal materials and manufactured through an integrated casting process. After casting, the elbow flanges still need to undergo multiple processes such as polishing and drilling.

[0003] All pipe flange drilling equipment is equipped with a positioning device for fixing the pipe flange, thus determining the hole position while fixing the pipe flange. However, the positioning device on the existing drilling equipment requires manual installation of the pipe flange into the positioning device, and manual operation is required again to remove the pipe flange after drilling is completed. Therefore, the operation steps are relatively cumbersome, resulting in low processing efficiency. In addition, the drilling position of some pipe flanges is inside the pipe flange. Due to the curvature of the pipe flange, the calibration sleeve cannot be inserted into the inside of the pipe flange. This makes it impossible to constrain and calibrate the drilling position of the drill bit, resulting in a large deviation in the drilling position and thus failing to ensure processing accuracy. Further improvements are needed. Utility Model Content

[0024] The lower edge of the seat block 716 is provided with a guide groove 7161, and the lifting block 717 is movably embedded in the guide groove 7161 to have the function of vertical movement. The upper outer wall of the seat block 716 is also screwed with a vertically arranged adjusting bolt 718. The threaded end of the adjusting bolt 718 extends vertically downward into the guide groove 7161 and is rotatably connected to the lifting block 717.

[0025] A non-circular limiting cavity 754 is also provided at the intersection of the flat surface 753 and the inner wall of the second corner groove 751.

[0026] An arc-shaped flat-bottomed recessed cavity 743 is provided on the rear edge of the bottom surface of the first corner groove 741.

[0027] The base plate 1 has a slot 101 located between the electric slide table 2 and the frame 71. The slot 101 also has a vertically distributed U-shaped receiving plate 9. The opening side of the U-shaped receiving plate 9 is set to the left and fixed on the right outer wall of the fixed mold base 74. The right edge of the upper opening of the U-shaped receiving plate 9 has a notch 91 that cooperates with the drill bit 6.

[0028] Working principle: Take a bent flange and place one end into the first corner groove 741 on the fixed mold base 74. Then, insert the other end of the bent flange into the first arc-shaped limiting groove 7141 on the support block 714. At the same time, insert the bypass connector that needs to be drilled on the bent flange into the first arc-shaped opening groove 742. Then, extend the telescopic end of the first positioning cylinder 78 in the driving positioning mechanism 7 to drive the moving mold base 75 to move downward until the side of the fixed mold base 74 facing the moving mold base 75 is exposed. The wall and the outer wall of the moving mold base 75 facing the fixed mold base 74 are in contact with each other. At this time, the second corner groove 751 on the moving mold base 75 is pressed onto the bent flange to fix one end of the bent flange. At the same time, the telescopic end of the second positioning cylinder 713 is driven to extend outward to drive the pressure block 715 downward with the help of the lifting plate 712 until the second arc-shaped limiting groove 7151 on the pressure block 715 is pressed against the other end of the bent flange. This completes the automatic positioning of the bent flange.

[0029] Next, the telescopic end of the first shift cylinder 73 in the drive calibration unit extends outward to drive the second shift cylinder 79 and the diagonal brace 710 to move backward with the help of the moving plate 72. At the same time, the telescopic end of the second shift cylinder 79 is driven to extend outward to drive the diagonal brace 710 to move to the right. This causes the end of the diagonal brace 710 to first extend into the inside of the bent flange through the front opening of the bent flange, and then extend to the right into the bypass joint on the bent flange. At this time, the calibration sleeve 711 reaches the right side of the drilling point.

[0030] Next, the drilling motor 3 in the main unit is started to rotate its rotating shaft, which in turn drives the drill bit 6 to rotate through the extension shaft 4 and the chuck 5. Then, the moving end of the electric slide table 2 is driven to move to the left, which in turn drives the drill bit 6 to move to the left through the extension shaft 4 and the chuck 5 (existing technology). This allows the drill bit 6 to pass through the notch 91 on the U-shaped receiving plate 9 and gradually approach the calibration sleeve 711. Finally, it passes concentrically through the calibration sleeve 711 and extends into the bypass joint of the bent pipe flange, thereby completing the drilling operation inside the bypass joint. The debris generated during the drilling process will be discharged downward through the channel formed between the U-shaped receiving plate 9 and the outer right wall of the fixed mold base 74.

[0031] After drilling is completed, first drive the moving end of the electric slide table 2 to move to the right so that the drill bit 6 moves away from the bent flange and the U-shaped receiving plate 9 in turn. Then turn off the drilling motor 3 so that the drill bit 6 stops rotating. Next, drive the extension and retraction ends of the first shift cylinder 73 and the second shift cylinder 79 to retract inward so that the calibration sleeve 711 moves away from the inside of the bent flange with the help of the diagonal brace 710. Then drive the extension and retraction ends of the first positioning cylinder 78 and the second positioning cylinder 713 to retract inward so that the moving mold base 75 and the pressure block 715 move upward. Finally, remove the bent flange.

[0032] By turning the adjusting bolt 718, the lifting block 717 can be moved up or down inside the guide groove 7161 based on the principle of spiral connection. Then, with the help of the diagonal brace 710, the calibration sleeve 711 can be moved synchronously, thereby adjusting the vertical height of the calibration sleeve 711 to ensure the accuracy of the drilling position.

[0033] This invention can automatically and quickly complete the positioning and installation of bent pipe flanges without the need for repeated manual operations, thereby simplifying the operation steps and improving processing efficiency. In addition, the calibration unit can be used to extend the calibration sleeve 711 into the inside of the bent pipe flange and accurately reach the drilling position, thereby effectively constraining and calibrating the drilling position of the drill bit, thereby reducing the deviation of the drilling position and ensuring processing accuracy.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
