Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, specifically to a multi-axis linkage precision drilling equipment for medical thin-walled tubing. Background Technology

[0002] In the field of medical rehabilitation equipment manufacturing, thin-walled medical tubing is a core component of many devices (such as intelligent upper and lower limb active and passive rehabilitation machines). The precision, location, and cleanliness of its drilling directly determine the performance and safety of the medical rehabilitation equipment. With the continuous development of medical technology, clinical requirements for the refinement and multi-functionality of medical rehabilitation equipment are increasing, which in turn places higher standards on the drilling of thin-walled medical tubing. This requires not only high-precision drilling at different locations on the tubing but also meeting requirements such as multi-angle oblique drilling and stable batch processing.

[0003] Currently, the industry mostly uses general-purpose drilling equipment for drilling thin-walled medical tubing. This type of equipment generally has many limitations, including:

[0004] 1. The drilling direction is singular, making multi-dimensional processing impossible. When dealing with the drilling needs of complex pipe fittings, multiple sets of tooling fixtures or multiple machines need to be used in coordination, which greatly increases production costs and processing cycle.

[0005] 2. The clamping and positioning method is unreasonable. Thin-walled pipes are prone to deformation during clamping, and repeated clamping during workstation switching will introduce accuracy errors, making it difficult to improve the product qualification rate.

[0006] 3. The processing flow has a low degree of automation. From pipe loading and station transfer to angle adjustment, it relies heavily on manual intervention, which is not only inefficient but also makes it difficult to ensure processing consistency.

[0007] 4. The lack of an effective real-time waste cleaning mechanism means that the waste generated during drilling can affect the processing accuracy, and the residual waste will reduce the surface cleanliness of the pipe fittings, which does not meet the hygiene standards for the production of medical rehabilitation devices.

[0008] 5. The overall structure of the equipment is not compact enough, the transmission and positioning modules are not stable enough, deviations are prone to occur during operation, and maintenance and repair are difficult in the later stage.

[0009] Against this backdrop, developing a drilling equipment for medical thin-walled tubes that can achieve multi-dimensional, high-precision, and automated drilling while also ensuring clamping stability and waste removal is crucial for overcoming current processing bottlenecks and meeting the upgrading needs of medical rehabilitation device manufacturing.

[0043] Compared with the prior art, the beneficial effects of the present invention are:

[0044] 1. Multi-dimensional processing coverage, adapting to the complex drilling needs of thin-walled pipes.

[0045] This equipment integrates vertical drilling components and horizontal drilling components, which can respectively complete vertical drilling on the top surface of the pipe and horizontal drilling on the side wall, meeting the processing requirements of different positions of medical thin-walled pipes.

[0046] The horizontal drilling assembly is equipped with a three-stage angle adjustment structure consisting of a steering frustum, a vertical steering wheel, and a horizontal steering wheel. It can achieve drilling at different angles in the horizontal direction by adjusting the overall steering of the steering frustum, the spatial angle of the vertical steering wheel, and the drill bit angle of the horizontal steering wheel. The vertical drilling assembly, on the other hand, uses a flip drive motor to flip the flip bridge plate, which can flexibly adjust the tilt angle of the vertical drilling to achieve inclined hole processing.

[0047] The synergistic operation of the two components breaks the limitation of a single drilling direction, enabling multi-axis linkage and all-round machining.

[0048] 2. Precise and stable clamping and positioning prevent deformation during the processing of thin-walled pipe fittings.

[0049] The transfer clamping assembly in this equipment adopts a double-layer clamping structure. The lower clamping block supports and positions the tube from both ends of the bottom, while the upper clamping block clamps and fixes it from both ends of the top, forming a stable clamping of the thin-walled tube and effectively avoiding the tube displacement problem caused by traditional single-sided or single-point clamping. Simultaneously, the clamping assembly is equipped with a lifting control module, which can adaptively adjust the processing height of the tube to adapt to the size requirements of different specifications of medical thin-walled tubes. The design of the first drive motor driving the rotating pallet to rotate 90° allows for switching between the clamping position and the drilling position without disassembling the tube, reducing accuracy errors caused by repeated clamping and further ensuring processing stability.

[0050] 3. High degree of automation, improving drilling efficiency.

[0051] The transmission and positioning of this equipment are fully automated. The sliding drive module drives the transverse slide to slide along the guide rail through the drive screw, which can accurately transfer the clamped pipe to the vertical or horizontal drilling position, replacing manual handling and adjustment, and greatly shortening the position switching time.

[0052] During horizontal drilling, the rotation of the steering platform, the automatic locking of the positioning slider, and the position adjustment of the extension cylinder allow for rapid setting of the drilling position and angle. During vertical drilling, the tilting drive motor adjusts the tilting bridge plate angle via belt drive, eliminating the need for manual adjustment. The entire processing flow requires minimal manual intervention, significantly improving the efficiency of batch processing.

[0053] 4. Real-time waste removal ensures drilling accuracy and pipe cleanliness.

[0054] The vertical drilling assembly in this equipment is equipped with an independent water supply and flushing system. The water pump delivers clean water from the water supply tank to the storage tank, and then sprays it precisely onto the drilling area through the flushing bend. This can flush away the metal debris generated during the drilling process in real time, preventing the debris from adhering to the surface of the pipe or getting stuck between the drill bit and the pipe. This not only prevents the debris from scratching the smooth surface of the thin-walled medical pipe, but also prevents the debris from affecting the drilling accuracy.

[0055] Meanwhile, the drilling workbench is equipped with a water collection square trough and a T-shaped drainage trough, so that the wastewater and debris after rinsing can be discharged in time, keeping the processing area clean and meeting the hygiene standards for medical pipe processing.

[0056] 5. The structure is compact and reasonable, and the equipment has strong operational stability.

[0057] The electrical control integrated box, drilling worktable, and support base plate in this equipment adopt an integrated structure with welding fixation. The plug-in fixing slots at both ends of the support base plate facilitate the overall installation and positioning of the equipment, improving the stability of the equipment during operation. All transmission mechanisms use bevel gear transmission or belt transmission, ensuring high transmission accuracy. The coordinated design of the guide rail and sliding limit port guarantees the straightness of the horizontal sliding block during movement, preventing displacement deviations from affecting drilling accuracy. Furthermore, the functional modules are clearly laid out; vertical drilling, horizontal drilling, and transfer clamping components can operate independently or in tandem, facilitating later maintenance and repair.

[0109] Start the third drive motor 35, which drives the horizontal steering wheel 36 to rotate a certain angle through the bevel gear transmission mechanism to adjust the drilling angle;

[0110] Start the steering drive module 28, which drives the vertical steering wheel 30 to rotate, thereby adjusting the spatial drilling angle;

[0111] Horizontal drilling of medical thin-walled tubular parts was performed using a specific type of horizontal drilling bit 37.

[0112] When it is necessary to switch the drilling direction, control the upper clamping block 19 to retract to its original position and release the clamping and positioning of the thin-walled pipe. After that, the thin-walled pipe is completely clamped and positioned by the lower clamping block 17.

[0113] Start the first drive motor 14, which drives the rotating pallet 15 to rotate 90° through the bevel gear transmission mechanism, so that the rotating pallet 15 is in a horizontal state, thereby realizing the flexible switching between the clamping part and the drilling position.

[0114] When performing vertical drilling:

[0115] First, control the transfer clamping assembly to move laterally in the opposite direction to directly below the flip bridge plate 41. Then, start the two water supply pumps 55 respectively. The water supply pumps 55 draw clean water from the water supply tank 53 and inject it into the water storage tank 58. Open the flow regulating valve 60, and clean water is sprayed out through the flushing bend 59 to wash away the waste attached to the medical thin-walled tubing. The waste is flushed into the water collection trough 61 by the clean water and then discharged through the T-shaped drainage trough 62.

[0116] Two flip drive motors 46 are started respectively. Through the transmission of the bevel gear transmission mechanism, the two driving wheels 47 are driven to rotate. Then, through the transmission belt 52, the driven wheel 51 is driven to rotate, which in turn drives the flip wheel 50 to rotate, thereby adjusting the working angle of the flip bridge plate 41 to adapt to drilling at different angles.

[0117] Install a specific type of vertical drilling bit 44 onto the drilling feed module 43, start the drilling control module 42, drive the drilling feed module 43 to rotate and feed, and perform drilling on the top surface of the medical thin-walled tube.

[0118] During vertical drilling, repeating the above-mentioned waste washing operation can clean up the waste generated during vertical drilling in real time.

[0119] After the slanted hole is drilled, the medical thin-walled tubing is removed from the transfer clamping assembly.

[0120] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
