Description

Technical Field

[0001] This utility model relates to the field of flange processing technology, specifically a self-clamping flange processing drilling machine. Background Technology

[0002] Flange processing refers to a series of processes such as cutting, machining, grinding and drilling of flanges to make them meet the requirements for use. Flanges are important components for connecting pipes, valves and equipment. They are used to connect two pipes or to seal the end of a pipe to ensure the safety and stability of the pipeline system.

[0003] In the prior art, patent publication number CN212495531U discloses a drilling machine for flange processing, including a frame, a placement table and a lifting drilling device on the frame; it also includes two sets of hydraulic cylinders, a column, a lifting ring and four sets of clamping and positioning devices. The bottom end of the column is fixedly connected to the frame, and the top end of the column is fixedly connected to the bottom end of the placement table. The lifting ring is sleeved on the outside of the column. The bottom ends of both sets of hydraulic cylinders are fixedly connected to the frame, and the top output ends of both sets of hydraulic cylinders are provided with piston rods. The top ends of the two sets of piston rods are respectively fixedly connected to the left and right sides of the bottom end of the lifting ring. The four sets of clamping and positioning devices... Each includes an inclined plate, a driving plate, and a driving rod. The four sets of inclined plates are respectively installed on the left, right, front, and rear sides of the bottom end of the placement platform. A linear slide rail is provided on the bottom inclined surface of the inclined plate, and a sliding block is slidably arranged on the linear slide rail. The driving plate is located below the inclined plate and is fixedly connected to the sliding block. The top of the driving plate is bent upward into a vertical state to form a positioning part. A positioning plate for positioning the flange is provided on the side of the positioning part facing the placement platform. The top of the positioning part is bent horizontally towards the placement platform to form a pressing part. One end of the driving rod is hinged to the top of the lifting ring, and the other end of the driving rod is hinged to the bottom end of the driving plate.

[0004] This type of flange processing drilling machine has the following disadvantages: when processing flanges, the flange needs to be placed on the upper end of the placement table first, and then the positioning plate is fixed and clamped by manually rotating the threaded rod. The flange clamping efficiency is low. Therefore, we propose a self-clamping flange processing drilling machine. Utility Model Content

The lower end of the output shaft of the motor 12 passes through the round hole at the upper end of the slide plate 10 and is fixedly connected to the upper end of the drill bit 11. The input terminal of the motor 12 is electrically connected to the control switch group 1. At the output end of 5, a lead screw 13 is rotatably connected between the upper and lower side walls of the slide groove 2 8. The lead screw 13 is threadedly connected to the slider 2 9. A motor 3 14 is provided at the upper end of the base 1. The lower end of the output shaft of the motor 3 14 passes through the round hole at the upper end of the base 1 and is fixedly connected to the upper end of the lead screw 13. The input end of the motor 3 14 is electrically connected to the output end of the control switch group 15. Then, adjust the position of the clamping seat 41 according to the diameter of the flange, rotate the knob 7, and the knob 7 drives the lead screw 1 6 to rotate, which in turn drives the slider 1 3 to slide the flange along the slide groove 2 until the flange is aligned with the drill bit 11 at the drilling position. Then, the control switch group 15 turns on motor 12, which drives drill bit 11 to rotate. Then, the control switch group 15 turns on motor 14, which drives lead screw 13 to rotate and drive slider 9 to drive drill bit 11 to slide along slide groove 8, thereby drilling a hole in the flange. After drilling is completed, according to the vertical direction of the hole to be drilled in the flange, since motor 5 is a servo motor, the angle of rotation of the output shaft can be adjusted with the servo controller. The control switch group 15 controls motor 5 to drive clamping seat 41 to drive the flange to rotate at the corresponding angle to drill the second hole, until drilling is completed.

[0022] Clamping mechanism 4: It includes a clamping seat 41, a rotating column 42, a pulling block 43, a pull rod 44, a sliding groove 45, a sliding block 46, and a clamping block 47. The clamping seat 41 is rotatably connected to the middle of the base 1. The rotating column 42 is rotatably connected to the middle of the bottom wall of the clamping seat 41. The outer surface of the rotating column 42 is provided with evenly distributed pulling blocks 43. The upper end of each pulling block 43 is rotatably connected to a pull rod 44. The upper end of the clamping seat 41 is provided with evenly distributed sliding grooves 45. The sliding blocks 46 are slidably connected inside each sliding groove 45. The side of the pull rod 44 away from the center of the rotating column 42 is rotatably connected to the lower end of the vertically adjacent sliding block 46. The upper end of each sliding block 46 is provided with a clamping block 47. The clamping mechanism 4 also includes a drive bar 48 and an electric push rod 49. The drive bar 48 is located on the rotating column 42. At the lower end of the outer surface, an electric push rod 49 is rotatably connected inside the rotating seat on the front side wall of the clamping seat 41. The rear end of the telescopic end of the electric push rod 49 is rotatably connected to the drive bar 48. The input end of the electric push rod 49 is electrically connected to the output end of the control switch group 15. Then, the electric push rod 49 is turned on by the control switch group 15. The electric push rod 49 pushes the drive bar 48 to drive the rotating column 42 to rotate. The rotation of the rotating column 42 will drive the pulling block 43 to change position. The pulling block 43 pulls the pull rod 44 to change angle, thereby pulling the three sliding blocks 46 to slide towards the middle of the clamping seat 41 and clamp the flange. By driving the rotating column 42 to rotate through the electric push rod 49, the pulling block 43 pulls the pull rod 44 to pull the sliding block 46, causing the three clamping blocks 47 to slide towards the middle of the clamping seat 41 at the same time, thereby realizing the clamping of the flange and improving the flange clamping efficiency.

[0023] The working principle of the self-clamping flange processing drilling machine provided by this utility model is as follows: When processing the flange, the flange to be processed needs to be placed in the upper middle part of the clamping seat 41. Then, the electric push rod 49 is turned on by the control switch group 15. The electric push rod 49 pushes the drive bar 48 to drive the rotating column 42 to rotate. The rotation of the rotating column 42 will drive the pulling block 43 to change position. The pulling block 43 pulls the pull rod 44 to change angle, thereby pulling the three sliding blocks 46 to slide towards the middle of the clamping seat 41 and clamp the flange. Then, the position of the clamping seat 41 is adjusted according to the diameter of the flange. The knob 7 is turned. The knob 7 drives the lead screw 6 to rotate and the transmission slider 3 drives the flange to rotate. The flange slides along the slide groove 2 until the position where the flange needs to be drilled corresponds to the drill bit 11. Then, the control switch group 15 turns on the motor 12, which drives the drill bit 11 to rotate. The control switch group 15 then turns on the motor 14, which drives the lead screw 13 to rotate and the transmission slider 9 to drive the drill bit 11 to slide along the slide groove 8, thereby drilling the flange. After drilling is completed, according to the vertical direction of the flange to be drilled, since the motor 5 is a servo motor, the rotation angle of the output shaft can be adjusted with the help of the servo controller. The control switch group 15 controls the motor 5 to drive the clamping seat 41 to rotate the flange by the corresponding angle to drill the second hole, until drilling is completed.

[0024] It is worth noting that, in the above embodiments, the first motor 5 can be THA130302B, the second motor 12 can be SB-3.8 / 380Y, the third motor 14 can be 110BYGH1.8, the electric push rod 49 can be LX835, and the control switch group 15 is provided with buttons that correspond one-to-one with the first motor 5, the second motor 12, the third motor 14 and the electric push rod 49 and control their switching.
