Description

Technical Field

[0001] This invention relates to the field of interbody fusion device processing technology, specifically a fully automated processing tooling for the production of interbody fusion devices. Background Technology

[0002] Interbody fusion devices, as key implants in spinal surgery, have complex structures and require extremely high precision. They are often made of difficult-to-process materials such as PEEK or titanium alloys. They are one of the main implants for achieving fusion of adjacent intervertebral spaces in the spine, and their safety and effectiveness directly affect the bony fusion of adjacent vertebrae.

[0003] Currently, the industry commonly uses CNC machining for intervertebral fusion devices. During the machining process, manual clamping is usually performed using contour jigs. The clamping force control is coarse, and manual or simple pneumatic clamping methods cannot guarantee a uniform distribution of clamping force. This can easily damage the surface of PEEK workpieces or cause elastic deformation of titanium alloy parts. It can also easily lead to over-positioning or under-positioning, resulting in stress accumulation or unstable support inside the workpiece. Stress release after machining can cause springback deformation, or vibration can occur during machining, resulting in out-of-tolerance product dimensions. Moreover, the above-mentioned machining relies too much on manual operation, which is not only inefficient but also makes it difficult to guarantee consistency in mass production.

[0004] Therefore, it is necessary to provide a fully automated machining tooling for the production of interbody fusion devices to solve the above problems. Summary of the Invention

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figure 1-10 The present invention provides a technical solution: a fully automatic processing fixture for the production of intervertebral fusion devices, including a frame 1, an operating table 2, a clamping mechanism 3, a first processing mechanism 4, and a second processing mechanism 5. The operating table 2 is located on the front side of the frame 1. The clamping mechanism 3, the first processing mechanism 4, and the second processing mechanism 5 are all located inside the frame 1. The clamping mechanism 3 is used to automatically feed and clamp the intervertebral fusion device raw materials. The first processing mechanism 4 and the second processing mechanism 5 are used to process the raw materials.

[0043] Specifically, such as Figure 1 and Figure 2As shown, the interior of the frame 1 is provided with at least a processing area, an equipment area one, and an equipment area two. Equipment area one is located on the side of the processing area, and equipment area two is located on the top of the processing area. A door 11 is slidably connected to the front of the frame 1. The door 11 is located on one side of the operating table 2 and corresponds to the position of the processing area. The door 11 is preferably opened and closed by electric drive. The door 11 is used to open and close the processing area, so that the interior of the frame 1 forms a closed environment and avoids dust generated during processing from spreading and affecting the processing environment.

[0044] A dust collection box 12 is provided on the front side of the frame 1. The dust collection box 12 is located below the door 11 and is used to collect large particles of debris generated during the processing of the intervertebral fusion device.

[0045] The side of the frame 1 is provided with an equipment door 13, which corresponds to the position of the equipment area 1. The equipment door 13 is used to open and close the equipment area, which facilitates the maintenance of the equipment and the loading of raw materials into the clamping mechanism 3.

[0046] Specifically, such as Figure 1 and Figure 2 As shown, the operating console 2 is equipped with a display screen and several operation buttons. The display screen is electrically connected to the processing system, which includes a control module and an analysis module. The control module is electrically connected to the door 11, the clamping mechanism 3, the first processing mechanism 4, and the second processing mechanism 5. The control module is used to control the opening and closing of the door 11, the feeding and clamping of the clamping mechanism 3, the processing operation of the first processing mechanism 4, and the processing operation of the second processing mechanism 5. The analysis module is signal-connected to the clamping mechanism 3. The analysis module is used to obtain the clamping parameters of the raw material and then adjust the clamping condition of the clamping mechanism 3 to ensure that the clamping force of the raw material is stable during processing and that there is no under-clamping or over-clamping of the raw material.

[0047] Specifically, such as Figure 3 As shown, the clamping mechanism 3 includes a fixed table 31, a first slide 32, a second slide 33, a hollow spindle 35, a feeding assembly 36, and a clamping head 37. The fixed table 31 is T-shaped. The first slide 32 and the second slide 33 are both mounted on the fixed table 31 and are slidably connected to the fixed table 31. The first slide 32 and the second slide 33 are both connected by a motor screw drive. The movement directions of the first slide 32 and the second slide 33 are perpendicular to each other. The first slide 32 is located in the equipment area 1, and the second slide 33 is located in the processing area. The hollow spindle 35 is mounted above the first slide 32, the feeding assembly 36 is mounted on the hollow spindle 35, and the clamping head 37 is located at one end of the hollow spindle 35 near the second slide 33. The clamping head 37 is located in the processing area.

[0048] Furthermore, such as Figure 4As shown, a drive assembly 34 is provided on the slide 32. The drive assembly 34 includes a connecting seat 341, a sealing plate 344, and a motor 345. The connecting seat 341 is fixed on the side of the slide 32 away from the slide 33. A bearing seat 342 is fixedly connected to the top of the connecting seat 341 away from the slide 33. A fixed seat 343 is fixedly connected to the top of the end of the slide 32 near the slide 33. A hollow spindle 35 is located on the sealing plate 344 and the bearing seat 342. The hollow spindle 35 is connected to the sealing plate 344 and the bearing seat 342 by bearings. The motor 345 is fixed on the top of the slide 32. The output end of the motor 345 is connected to the hollow spindle 35 by a pulley drive.

[0049] The sealing plate 344 is fixed to the side of the fixed base 343 away from the hollow spindle 35. The sealing plate 344 is located at the junction of the processing area and the equipment area. The sealing plate 344 is slidably connected to the frame 1. The sealing plate 344 is used to separate the processing area and the equipment area to prevent dust and debris generated during processing from flying and affecting the operation of the equipment in the equipment area.

[0050] Furthermore, such as Figure 6 and Figure 7 As shown, the hollow spindle 35 is provided with two sets of limiting holes 351, and each set of limiting holes 351 has three holes equidistantly arranged along the circumference of the hollow spindle 35.

[0051] Furthermore, such as Figure 4 , Figure 6 and Figure 7 As shown, the feeding assembly 36 includes a telescopic rod 362 and two sets of clamping parts, the positions and numbers of which correspond to the positions of the two sets of clamping parts and the two sets of limiting holes 351;

[0052] A slide block 361 is fixedly connected to the side of the bearing housing 342 away from the sealing plate 344. A telescopic rod 362 is fixed on the slide block 361. The output end of the telescopic rod 362 extends through the slide block 361 and matches the inner diameter of the hollow spindle 35. When the telescopic rod 362 extends, it can push the raw material inside the hollow spindle 35 to the side away from the telescopic rod 362. The distance of each push is set by the operator using the button on the control panel 2, thereby realizing automatic fixed-length feeding.

[0053] Furthermore, such as Figure 6 and Figure 7As shown, the clamping part includes a limiting cylinder 363 and rollers 365. The limiting cylinder 363 is located inside the limiting hole 351 and is fixedly connected to the hollow main shaft 35. A slide block 364 and a spring 366 are provided inside the limiting cylinder 363. The slide block 364 is slidably connected to the limiting cylinder 363. The spring 366 is located between the limiting cylinder 363 and the slide block 364, and its two ends are fixedly connected to the limiting cylinder 363 and the slide block 364, respectively. The roller 365 is located at the end of the slide block 364 and is rotatably connected to the slide block 364. When the material is inside the hollow main shaft 35, the three rollers 365 of the two sets of clamping parts clamp, support, and position the material, so that the axis of the material is aligned with the hollow main shaft 35. The axes of the main shaft 35 are collinear, ensuring the material remains horizontal. When the diameter of the material is small, the limiting cylinder 363 extends under its own elastic force, pushing the slide block 364 closer to the axis of the hollow main shaft 35 to support and clamp the material. When the diameter of the material is large, the limiting cylinder 363 is compressed and contracted by the material, while the material simultaneously pushes the slide block 364 away from the axis of the hollow main shaft 35. During this process, the slide block 364 continues to support and clamp the material. When the material is pushed inside the hollow main shaft 35, the roller 365, connected to the bearing of the slide block 364, can roll while supporting and clamping the material, thus conveying the material.

[0054] Furthermore, such as Figure 6 , Figures 8-10 As shown, the clamping head 37 includes a chuck 371, a plurality of jaws 372, a plurality of clamping adjustment parts, and a plurality of pressure sensors 378. The chuck 371 is fixed to the end of the hollow spindle 35 near the slide block 33. The plurality of jaws 372 are equidistantly arranged along the circumference of the chuck 371 on the side of the chuck 371 away from the hollow spindle 35. The jaws 372 are slidably connected to the chuck 371. The number and position of the clamping adjustment parts correspond to the number of jaws 372. The clamping adjustment parts are arranged on the jaws 372 and are used to fine adjust the clamping force so that the clamping force of the material is stable. The pressure sensors 378 are arranged on the clamping adjustment parts and are used to detect the clamping force.

[0055] Furthermore, such as Figures 8-10 As shown, the clamping adjustment part includes a jaw 373, a support frame 376, and a support plate 377. The jaw 373 is fixed to one end of the jaw 372 near the axis of the hollow spindle 35. A limit groove 3731 is provided on the side of the jaw 373 near the axis of the hollow spindle 35. The support frame 376, the support plate 377, and the pressure sensor 378 are arranged from the outside to the inside along the radial direction of the chuck 371. The support frame 376 is fixedly connected to the support plate 377, and the support plate 377 is fixedly connected to the pressure sensor 378.

[0056] Four sets of telescopic rods 375 are fixedly connected to the side of the gripper 373 away from the axis of the hollow spindle 35. The output end of the telescopic rod 375 passes through the connecting seat 374 and the gripper 373. The output end of the telescopic rod 375 is hinged to the support frame 376. The hinge is slotted, which provides an adjustable range of motion for the support frame 376 to be raised and lowered. The limit of its movement is determined by the mechanical size of the slot, which improves the applicability of the clamping adjustment part.

[0057] It should be noted that the slide block 361 preferably adopts a linear motor drive structure; the drive mechanism for driving the jaws 372 to slide, tighten, and loosen on the chuck 371 is not shown in the figure; the pressure sensor 378 is provided with an anti-slip layer on the side near the axis of the chuck 371, which is not shown in the figure; the jaws 372 are usually set in three groups; the telescopic rod 1 362 and the telescopic rod 2 375 can be pneumatically, hydraulically, or electrically driven according to actual needs; the four groups of telescopic rod 2 375 can adjust the support status of the corresponding support frame 376 at different positions in the front, back, left, and right by different telescopic lengths, thereby meeting the clamping of different materials.

[0058] Based on the above structural description, the drive mechanism for driving the jaws 372 to slide, tighten, and loosen on the chuck 371 is activated, causing the jaws 372 to move towards the axis of the chuck 371 to clamp the fixed-length material pushed out from the hollow spindle 35. The moving distance of the chuck 371 is set by the operator using the buttons on the control panel 2. After the material is clamped, the pressure sensor 378 acquires the pressure data during the material clamping process. The second telescopic rod 375 extends, which pushes the support frame 376 closer to the axis of the chuck 371, thereby causing the support plate 377 to move closer to the axis of the chuck 371, further clamping the material with the anti-slip layer until the pressure data increases to the required range. The second telescopic rod 375 retracts, which pulls the support frame 376 away from the axis of the chuck 371, thereby moving the support plate 377 away from the axis of the chuck 371, reducing the clamping force of the anti-slip layer on the material until the pressure data decreases to the required range.

[0059] Specifically, such as Figure 3 and Figure 4 As shown, the processing mechanism 4 includes a motor 41 and a processing head 42. The motor 41 is fixed on the top of the slide 33, and the processing head 42 is fixed on the output end of the motor 41. The processing head 42 is located on the side of the motor 41 close to the clamping head 37. When the motor 41 is started, it drives the processing head 42 to rotate, thereby enabling the processing of the raw materials clamped on the clamping head 37.

[0060] Specifically, such as Figure 3 and Figure 4As shown, the second processing mechanism 5 includes a dual-axis moving base 51, a single-axis moving base 52, a rotating table 53, and a second processing head 54. The dual-axis moving base 51 is located in the second equipment area, and the single-axis moving base 52 is located in the processing area. The single-axis moving base 52 is mounted on the dual-axis moving base 51, the rotating table 53 is mounted on the single-axis moving base 52, and the second processing head 54 is mounted on the rotating table 53. The second processing head 54 is a processing head with two processing directions, preferably two processing heads with mutually perpendicular processing directions. The dual-axis moving base 51 is used to drive the single-axis moving base 52 to move left and right and up and down along the direction of the door 11. The single-axis moving base 52 is used to drive the rotating table 53 to move in the tilting direction. The rotating table 53 is used to adjust the processing direction of the second processing head 54, thereby facilitating the second processing head 54 to process the raw material on the clamping head 37 at different angles.

[0061] A bellows cover 55 is installed at the junction of equipment area 2 and processing area. The bellows cover 55 is used to separate the processing area and equipment area 2 to prevent dust and debris generated during processing from flying away and affecting the operation of equipment in equipment area 2.

[0062] It should be noted that the dual-axis moving base 51 preferably adopts a motor lead screw drive structure; the single-axis moving base 52 adopts a pneumatic drive structure; the dual-axis moving base 51 is also equipped with a bellows cover 55 to further prevent dust and debris from entering the transmission area; according to the positions of the clamping mechanism 3, processing mechanism one 4 and processing mechanism two 5, a tool magazine for easy tool changing is provided, which is not shown in the figure; a feeding device is provided directly below the clamping mechanism 3, which is not shown in the figure, for removing the processed intervertebral fusion device.

[0063] Working principle of the fully automated machining tooling for interbody fusion devices:

[0064] Step 1: Preparing and Enclosing the Processing Environment: The operator starts the equipment via control panel 2. The control module automatically closes the chamber door 11, creating a closed space inside the processing area of ​​the frame 1 to prevent dust and debris generated during subsequent processing from scattering and contaminating the equipment and workshop environment. Simultaneously, the dust collection box 12 is positioned to collect large particles of debris.

[0065] Step 2: Automatic feeding and precise positioning: The feeding component 36 is started, and the telescopic rod 362 moves to the corresponding position of the hollow spindle 35 under the drive of the slide block 361. Then the telescopic rod 362 extends into the hollow spindle 35 and pushes the intervertebral fusion device material stored in it towards the clamping head 37. The pushing length is preset by the operating table 2.

[0066] During the pushing process, the raw material passes through the channel of two sets of clamping parts composed of six rollers 365. Under the action of spring 366, the rollers 365 can adapt to raw materials of different diameters, always providing rolling support and radial positioning, ensuring that the axis of the raw material coincides with the axis of the hollow main shaft 35, achieving precise centering and smooth conveying, and realizing fixed-length feeding.

[0067] Step 3: Intelligent clamping and force feedback adjustment: When the material is pushed to the predetermined position, the chuck 371 of the clamping head 37 extends out of its front end. The drive mechanism of the chuck 371 is activated, driving all the jaws 372 to tighten towards the center in a synchronized manner. The material is initially clamped by the jaws 373. At the same time, the pressure sensor 378 installed on each clamping adjustment part monitors the clamping force in real time.

[0068] The analysis module acquires the clamping force data monitored in real time by the pressure sensor 378 and records it as f. i , i∈[1,n], n is the serial number corresponding to the total number of pressure sensors 378. The analysis module is set with an ideal clamping force range of (F1,F2). F1 is the minimum safe clamping force to ensure that the raw material does not shift or vibrate during processing, and F2 is the maximum allowable clamping force to avoid plastic deformation or internal damage to the surface of the raw material.

[0069] When f i When ∈ (F1, F2), the clamping force of the clamping adjustment unit on the raw material is normal, and the clamping is normal;

[0070] When f i When the value is ≤F1, the clamping force of the clamping adjustment part on the raw material is small, which is under-clamping and there is a risk of loosening during processing;

[0071] When f i When the clamping force is greater than or equal to F2, it indicates that the clamping adjustment unit has a large clamping force on the raw material, which is considered over-clamping and poses a risk of damaging the workpiece.

[0072] Several sets of clamping and adjusting parts have the following clamping conditions for the raw materials:

[0073] Scenario 1: All clamping adjustment units are in good condition for clamping the raw material, indicating normal clamping. Maintain the current clamping status.

[0074] Scenario 2: If two or more of the following conditions exist simultaneously: clamping pass, under-clamping, or over-clamping, and if several f i If the maximum clamping force difference is greater than F2-F1, the analysis module will issue an alarm. At this time, the clamping force of the clamping adjustment unit on the raw material is significantly different, making adjustment difficult. There may be a situation where the position of the clamping adjustment unit is offset, which should be handled by the staff.

[0075] If several f iIf the maximum clamping force difference is not greater than F2-F1, normal clamping adjustment is performed. For under-clamping: the control module controls the push rod of telescopic rod 375 corresponding to the under-clamping position to extend. Since its output end is hinged to the support frame 376, it will push the entire support frame 376, support plate 377, pressure sensor 378 and anti-slip layer on it as a whole to make a small supplementary clamping movement in the direction of the workpiece axis. For over-clamping: the control module controls the push rod of telescopic rod 375 to retract. Through the hinge point, it pulls the support frame 376, support plate 377 and pressure sensor 378 and anti-slip layer on it, moving the whole slightly away from the workpiece axis, thereby relieving the pressure on the workpiece. During this process, the pressure sensor 378 continuously acquires clamping force data until the clamping force enters the ideal range, and the telescopic rod 375 immediately stops moving.

[0076] Scenario 3: Several sets of clamping adjustment units are either under-clamped or over-clamped with the raw material. The drive mechanism that drives the jaws 372 to slide and tighten / unclamp on the chuck 371 is activated. For all under-clamped parts: the drive mechanism drives the jaws 372 to slide on the chuck 371 to tighten the raw material as a whole. For all over-clamped parts: the drive mechanism drives the jaws 372 to slide on the chuck 371 to unclamp the raw material as a whole. During this process, the pressure sensor 378 continuously acquires clamping force data until the clamping force enters the ideal range. The drive mechanism immediately stops moving and repeats this step only once. If Scenario 3 still occurs after repetition, the analysis module will issue an alarm prompt, and the operator will handle the situation.

[0077] This enables dynamic, adaptive, and fine-tuning intelligent clamping of raw materials, ensuring secure clamping without damaging the materials.

[0078] Step 4: Raw material processing: First station processing: After the clamping is secure, slide 2 33 moves on the fixed table 31, driving the entire processing mechanism 1 4 to the processing position. Motor 2 41 starts, driving the processing head 1 42 to rotate at high speed. Through the coordinated movement of slide 1 32 and slide 2 33, the clamped raw material is driven to perform precise two-dimensional planar movement relative to the rotating processing head 1 42, thereby completing the preliminary processing of one end of the raw material, such as end face forming, drilling, turning, etc.

[0079] The second station performs multi-angle machining: the dual-axis moving base 51 drives the second machining head 54 to be positioned in the left-right and up-down directions, the single-axis moving base 52 can perform tilting feed motion, and the rotating table 53 can adjust the machining direction of the second machining head 54 so that it can use two mutually perpendicular machining heads. Through the combined motion of the above three motion units, the second machining head 54 can approach the raw material from multiple angles and directions to complete the precision machining of features such as complex contours, inclined surfaces or intersecting holes.

[0080] Step 5: Unloading and Cycle: After all processing steps are completed, the clamping head 37 is released, and the unloading device located directly below the operating table 2 removes the processed intervertebral fusion device. Then, the feeding assembly 36 performs the next fixed-length loading and starts a new round of processing cycle.

[0081] Through the above methods, precise adaptive clamping of the interbody fusion device raw materials can be achieved, effectively suppressing deformation, and realizing continuous, efficient, high-precision, and clean automated production of interbody fusion devices from raw materials to finished products.
