Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to a high-efficiency positioning and adjustment device for stainless steel pipe processing. Background Technology

[0002] Stainless steel pipes are used in some applications that require drilling to meet user needs. Drilling steel pipes requires the use of a fixing device to keep the steel pipe stable during the drilling process, thereby ensuring the accuracy and stability of the drilling.

[0003] A Chinese utility model patent application (CN214559245U) discloses a fixing device for drilling steel pipes, specifically comprising: a base plate; a lateral adjustment mechanism disposed on the upper side of the base plate; a clamping and fixing mechanism connected to the upper side of the lateral adjustment mechanism; and a support plate fixedly connected to the middle of the upper end face of the lateral adjustment mechanism. This fixing device for drilling steel pipes facilitates clamping and supporting the inner wall of the steel pipe, effectively preventing deformation of the steel pipe during clamping, and allows for easy lateral movement adjustment of the clamped steel pipe, thereby improving the efficiency of steel pipe drilling.

[0004] The aforementioned patent also suffers from the following problems: it is inconvenient to adjust the angle of the stainless steel tube, making it impossible to quickly and accurately adjust the axial deflection angle of the stainless steel tube when processing inclined holes. This rigid and fixed working mode severely restricts the adaptability of the equipment to the processing of irregular holes, affecting not only processing accuracy and efficiency but also limiting the application range of the equipment under complex working conditions, making it difficult to meet the processing requirements of multi-angle inclined holes in fields such as fluid control and precision instruments.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This high-efficiency positioning and adjustment device for stainless steel pipe processing, through its adjustable structure, enables the steel pipe angle adjustment system to precisely rotate a double-ended threaded rod via a gear transmission mechanism driven by a first motor, achieving synchronous centering and clamping of the clamping frame and ensuring accurate and reliable positioning of the steel pipe.

The stainless steel pipe rotary drilling system achieves precise transmission of the rotating shaft via a second motor-driven worm gear mechanism. The self-locking characteristic of the worm gear ensures stable and reliable positioning of the steel pipe. The support plate achieves smooth rotation through the cooperation of a slider and a circular slide rail, effectively eliminating vibration deviations during rotation.

[0024] The adjusting structure 2 includes a support plate 201, a fixed frame 202, a rotating shaft 203, a rotating gear 204, a fixed seat 205, a movable rack 206, an electric push rod 207, a connecting plate 208, a connecting frame 209, a double-threaded rod 210, a guide rod 211, a clamping frame 212, a first gear 213, a first motor 214, and a second gear 215.

The double-ended threaded rod 210 is movably mounted on the connecting frame 209. The guide rod 211 is mounted on the connecting frame 209. The clamping frame 212 is movably mounted on the double-ended threaded rod. The clamping frame 212 is connected to the guide rod 211 on the rod 210. The first gear 213 is mounted on the double-threaded rod 210. The first motor 214 is mounted on the connecting frame 209. The second gear 215 is mounted on the first motor 214 and meshes with the first gear 213. A pair of clamping frames 212 are provided, symmetrically arranged on the double-threaded rod 210. The threads at both ends of the double-threaded rod 210 are in opposite directions, which can drive the pair of clamping frames 212 to move closer or further apart. When it is necessary to adjust the angle of the steel pipe, the steel pipe is placed on the pair of clamping frames. Between 212, the first motor 214 is driven, which in turn drives the second gear 215 to rotate. Under the action of the second gear 215, the first gear 213 drives the double-headed threaded rod 210 to rotate. A pair of clamping frames 212 approach each other and contact the two ends of the steel pipe to position the steel pipe. The electric push rod 207 is driven, which in turn drives the connecting plate 208 to move. The connecting plate 208 drives the moving rack 206 to move on the fixed seat 205. The rotating gear 204 drives the rotating shaft 203 to rotate on the fixed frame 202 under the action of the moving rack 206, thereby adjusting the position of the steel pipe.

[0025] Furthermore, the movable rack 206 is adapted to the fixed base 205, and the fixed frame 202 is provided with reinforcing ribs. The adapted movable rack 206 moves stably on the fixed base 205, and the reinforcing ribs increase the strength of the fixed frame 202.

The second motor 308 is mounted on the placement frame 304, and the drive end of the second motor 308 is connected to the worm gear 307. When it is necessary to drive the stainless steel tube to rotate for better drilling, the second motor 308 is driven. The second motor 308 can drive the worm gear 307 to rotate. Under the action of the worm gear 307, the worm wheel 305 drives the rotating shaft 306 to rotate. The support plate 201 rotates with the rotating shaft 306, thereby adjusting the position of the stainless steel tube to facilitate drilling. The support plate 201 slides on the circular slide rail 301 through the slider 302 on the connecting block 303, so that the rotation of the support plate 201 is stable.

[0028] Furthermore, the placement frame 304 is provided with reinforcing ribs, and a pair of sliders 302 are provided. The reinforcing ribs increase the stability of the placement frame 304, and the pair of sliders 302 can make the rotation of the support plate 201 more stable.

[0029] Furthermore, the second motor 308 is fixed to the placement frame 304 by bolts, and the slider 302 is adapted to the circular slide rail 301. The second motor 308, which is fixed by bolts, is easy to install and remove on the placement frame 304, and the adapted slider 302 slides more stably on the circular slide rail 301.

[0030] Furthermore, the clamping frame 212 is provided with a protective layer, and the electric push rod 207 is fixed to the support plate 201 by bolts.

The electric push rod 207, which is fixed by bolts, is easy to install and remove on the support plate 201.

[0031] Working principle: When the angle of the steel pipe needs to be adjusted, the steel pipe is placed between a pair of clamping frames 212. The first motor 214 is driven, which drives the second gear 215 to rotate. Under the action of the second gear 215, the first gear 213 drives the double-headed threaded rod 210 to rotate. The pair of clamping frames 212 move closer to each other and contact the two ends of the steel pipe, positioning the steel pipe. The electric push rod 207 is driven, which drives the connecting plate 208 to move. The connecting plate 208 drives the moving rack 206 to move on the fixed seat 205. The rotating gear 204 moves the moving rack. Under the action of 206, the rotating shaft 203 is driven to rotate on the fixed frame 202, thereby adjusting the position of the steel pipe. When it is necessary to drive the stainless steel pipe to rotate for better drilling, the second motor 308 is driven. The second motor 308 can drive the worm 307 to rotate. The worm wheel 305 drives the rotating shaft 306 to rotate under the action of the worm 307.
