Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to a clamping fixture for processing holes in cooling steel pipes. Background Technology

[0002] The primary purpose of perforating cooling steel pipes is to optimize their heat exchange performance and meet specific engineering requirements. By creating holes on the pipe surface, the contact area between the fluid and the pipe wall can be significantly increased, thereby improving heat transfer efficiency and allowing the cooling medium to absorb or release heat more quickly. The perforated design also promotes fluid turbulence, reduces the thermal resistance of the laminar boundary layer, and further enhances heat transfer. Furthermore, the perforated structure helps to evenly distribute fluid pressure, avoid localized overheating or flow dead zones, and ensure system stability. In specific applications, perforations may also be used to drain condensate, release gases, or achieve multiphase flow mixing to adapt to different process requirements. Simultaneously, a reasonable perforation layout can reduce the weight of the steel pipe and lower material costs without significantly weakening its structural strength. This design is widely used in chemical, energy, and HVAC systems. By precisely controlling the orifice diameter, spacing, and arrangement, it can flexibly match cooling requirements under different operating conditions, ultimately achieving efficient, energy-saving, and reliable thermal management.

[0003] Existing clamping fixtures for drilling holes in cooling steel pipes have shortcomings. First, they cannot reliably clamp the cooling steel pipes and cannot rotate the clamped pipes around the axis according to the drilling position.

The first vertical plate 2 and the movable vertical plate 7 are provided with annular grooves that cooperate with the anti-detachment support ring 304.

[0024] In this embodiment, an annular turntable and a rotary actuator for driving its rotation are installed in the annular inner cavity of the annular shell 301. The annular turntable has multiple arc-shaped push grooves along its circumference, and the outer end plate of the annular shell 301 has multiple radial sliding grooves along its circumference. The inner support claw 302 is slidably restricted in the radial sliding grooves, and the inner end of the inner support claw 302 is provided with an anti-dislodgement head that is slidably restricted in the arc-shaped push grooves. Other types of mechanical grippers can also be used as needed.

[0025] In this embodiment, the lead screw drive assembly 6 includes a lead screw drive motor 601, a lead screw 602, a guide rod, and a support plate 603. The movable end of the lead screw drive motor 601 is connected to the lead screw 602. The lead screw 602 is provided with movable support by two support plates 603 fixed on the horizontal base plate 1. The two support plates 603 are equipped with guide rods arranged side by side with the lead screw 602. The movable upright plate 7 has a lead screw hole that mates with the lead screw 602 and a guide hole that mates with the guide rod.

[0026] In this embodiment, a movable inner support assembly is also included. The movable inner support assembly consists of a drive push rod 12, a push plate 13, a support rod 14, and an inner support block 15. The cylinder of the drive push rod 12 is fixed on the horizontal base plate 1. The movable end of the drive push rod 12 is connected to one end of the support rod 14 via the push plate 13. The other end of the support rod 14 passes through the movable vertical plate 7 and the second mechanical gripper 8 and is connected to the inner support block 15.

[0027] In this embodiment, the inner support block 15 is a circular block 151 that matches the inner diameter of the cooling steel pipe. The circular block 151 has an opening clearance groove 152, a radial chip removal groove 153 and an axial chip removal groove 154. The bottom end of the radial chip removal groove 153 is connected to the axial chip removal groove 154, and the top end of the radial chip removal groove 153 is equipped with the opening clearance groove 152.

[0030] One specific application of this embodiment is: The cooling steel pipe is placed between the first and second mechanical grippers. An annular turntable inside the annular shell rotates under the drive of a rotary driver, causing an arc-shaped pusher groove to push the inner support claw radially within a radial groove. The arc-shaped anti-slip pad on the outer side of the inner support claw engages with the inner wall of the cooling steel pipe for reliable clamping. Simultaneously, an anti-detachment support ring in the annular groove prevents the grippers from separating from the steel pipe. A lead screw drive motor in the lead screw drive assembly rotates the lead screw, causing the movable vertical plate to move horizontally under the action of the lead screw and guide rod, adjusting the position of the second mechanical gripper to place the cooling steel pipe in a suitable processing position. After determining the opening position, the cooling steel pipe is drilled. When the opening position needs to be changed, a tilting drive motor drives the first mechanical gripper to rotate via an anti-slip belt transmission component, thereby causing the clamped cooling steel pipe to tilt around its axis. During the drilling process, debris falls into the steel pipe, and the vacuum cleaner works to suck it away through the suction pipe. Simultaneously, the drive push rod in the movable inner support assembly pushes the push plate, which in turn moves the support rod and the inner support block. The drilling clearance groove on the inner support block prevents interference with the drilling, and the radial and axial chip removal grooves guide the debris towards the suction pipe. The controller provides unified control over the lead screw drive motor, the first mechanical gripper, the second mechanical gripper, the tilting drive motor, the vacuum cleaner, and the drive push rod, achieving automated operation of the entire processing process.
