Description

Technical Field

[0001] This utility model relates to the field of medical device processing tooling technology, and in particular to a keel-shaped joint socket tooling. Background Technology

[0002] In the manufacturing or processing of glenoid-related medical devices, a high-precision and flexibly adjustable tooling is required to fix the glenoid. Traditional tooling may have problems such as inaccurate positioning, non-adjustable angles, or insecure fixation, which can lead to errors during the processing (such as grinding, drilling, etc.) or testing of the glenoid, affecting its quality and performance, and consequently its effectiveness in medical applications.

[0003] In view of this, it is necessary to develop a new type of joint socket tooling to meet the needs of high-quality machining. Summary of the Invention

[0004] The purpose of this invention is to provide a keel-shaped joint girder tooling with advantages such as accurate positioning, firm fixation, convenient operation and maintenance, and wide applicability, which can effectively improve the processing quality and efficiency of joint girder, so as to solve the above-mentioned technical problems.

[0005] To achieve the above technical solution, the technical solution of this utility model is as follows: A keel-shaped articulated gimbal tooling mainly includes a machine base connecting plate and a tooling body. The machine base connecting plate is used to connect the tooling to the machine base of the processing equipment, providing a stable installation foundation for the entire tooling. The tooling body is detachably installed on the machine base connecting plate, facilitating the installation, disassembly, and maintenance of the tooling. The tooling body further includes a support platform and an articulated gimbal placement seat. The support platform is centrally located on the machine base connecting plate, and its top is provided with an arc-shaped adjustment part. The articulated gimbal placement seat is adjustablely located on the arc-shaped adjustment part, and the angle is adjusted by an arc-shaped dovetail groove at the bottom that matches the arc-shaped adjustment part. The articulated gimbal placement seat is provided with a concave articulated gimbal placement cavity for placing the articulated gimbal. After adjusting the relative angle, the articulated gimbal placement seat and the support platform can be fixedly connected by fasteners to ensure the stability of the position and angle of the articulated gimbal during processing.

[0006] Furthermore, the peripheral side of the glenoid cavity is inclined. This inclined design helps to better fit the shape of the glenoid, allowing for more precise positioning when placing the glenoid, while also providing suitable operating space for machining tools (such as cutting tools) during processing, avoiding interference and improving machining accuracy.

[0007] Furthermore, a negative pressure airflow channel is provided inside the glenoid cavity, and a suction cup is installed on the glenoid cavity, connected to the negative pressure airflow channel. During glenoid placement, the negative pressure generated by the airflow channel allows the suction cup to firmly adhere to the glenoid, further enhancing its stability within the cavity and preventing displacement due to external forces (such as processing vibrations) during manufacturing. Moreover, the suction cup's height is significantly higher than the corresponding mounting surface on the glenoid cavity; this design allows the suction cup to more effectively contact and adhere to the glenoid, improving the adhesion effect.

[0008] Furthermore, a micro-moving clamping part is movably provided on the periphery of the spherical placement cavity of the glenoid fossa. After the glenoid fossa is placed in position, the micro-moving clamping part can further clamp the glenoid fossa from the periphery, working together with the adsorption effect of the suction cup to ensure that the glenoid fossa remains fixed in all directions, and will not loosen even under complex processing operations, thus ensuring processing quality.

[0009] Furthermore, the arc-shaped adjustment section is a protruding dovetail seat with a layer of grease applied to its surface. The presence of grease reduces the friction when the glenoid fossa is adjusted on the arc-shaped adjustment section, making the angle adjustment process smoother and more precise. The mating structure of the arc-shaped dovetail groove and the protruding dovetail seat not only ensures the stability of the glenoid fossa when adjusting the angle, but also withstands a certain machining load, preventing accidental displacement or shaking of the glenoid fossa during machining.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1) The adjustable design of the glenoid fossa on the arc-shaped adjustment part of the support platform allows for precise adjustment of the glenoid fossa angle according to different processing requirements. Combined with the inclined circumferential side design of the glenoid fossa's contour placement cavity, high-precision positioning of the glenoid fossa is achieved, effectively ensuring processing accuracy and enabling the processed glenoid fossa to better meet medical use requirements.

[0012] 2) The negative pressure adsorption system (including negative pressure airflow channels and suction cups) within the conformal placement cavity of the joint glenoid, along with the micro-movement clamping parts on the periphery, work together to provide an extremely stable fixation effect for the joint glenoid. Whether in simple processing operations or complex processing environments, it ensures that the joint glenoid will not shift or loosen, greatly improving processing quality and product qualification rate.

[0013] 3) The detachable connection between the tooling body and the machine base plate facilitates the installation and disassembly of the tooling, making it easy to use or maintain on different processing equipment. The grease-lubricated design of the arc-shaped adjustment section makes angle adjustment easy and convenient, reducing friction and wear during the adjustment process. At the same time, the structural design of each component of the tooling facilitates inspection and maintenance, enabling timely detection and resolution of problems, reducing maintenance costs, and improving the tooling's service life and efficiency.

[0014] 4) This tooling can adapt to the processing requirements of different models and specifications of glenoid fossae. By adjusting the angle of the glenoid fossae placement seat and utilizing the universal design of the glenoid fossae contour placement cavity, it can play a role in a variety of glenoid fossae-related processing technologies and has broad application prospects. It provides an efficient and practical tooling solution for the glenoid fossae medical device manufacturing industry.

[0015] In summary, this keel-shaped glenoid tooling has advantages such as accurate positioning, firm fixation, convenient operation and maintenance, and wide applicability. It can effectively improve the processing quality and efficiency of glenoids and meet the needs of the medical device manufacturing field for high-quality processing of glenoids.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Please see the appendix Figure 1As shown: A keel-shaped articulated girder tooling includes a machine base connecting plate 1 and a tooling body 2 detachably mounted on the machine base connecting plate 1; the tooling body 2 includes:

[0021] Support platform 21 is centrally located on the machine base connecting plate 1; the top of support platform 21 is provided with an arc-shaped adjustment part 211; and

[0022] The glenoid placement seat 22 is adjustablely mounted on the arc-shaped adjustment part 211. The bottom of the glenoid placement seat 22 is provided with an arc-shaped dovetail groove 221 that is adapted to the arc-shaped adjustment part 211. The glenoid placement seat 22 is provided with a concave glenoid contour placement cavity 222.

[0023] The glenoid cavity placement seat 22 and the support platform 21 are fixedly connected by fasteners after adjusting their relative angle. In this embodiment, the adjustable design of the glenoid cavity placement seat on the arc-shaped adjustment part of the support platform allows for precise adjustment of the glenoid cavity angle according to different processing requirements. Combined with the inclined circumferential surface design of the glenoid cavity's contoured placement cavity, high-precision positioning of the glenoid cavity is achieved, effectively ensuring processing accuracy and enabling the processed glenoid cavity to better meet medical usage requirements.

[0024] Based on the above embodiments, the peripheral side of the glenoid cavity 222 is inclined, which allows the cavity to better fit the shape of the glenoid. When placing the glenoid, it can be precisely positioned, restricting its freedom of movement within the cavity and ensuring positional accuracy during processing, thus preventing positional deviations from affecting processing quality.

[0025] Based on the above embodiment, a negative pressure airflow channel is provided inside the urn-shaped placement cavity 222; a suction cup is provided on the urn-shaped placement cavity 222; the suction cup is connected to the negative pressure airflow channel, and the negative pressure airflow channel inside the urn-shaped placement cavity is connected to the suction cup on the placement cavity, with the height of the suction cup being much higher than the height of the corresponding mounting surface. When the urn is placed in the placement cavity, the negative pressure system is activated, allowing the suction cup to fully contact the surface of the urn, and the urn is firmly fixed in the placement cavity through negative pressure adsorption. This adsorption method is not affected by external forces such as processing vibration, providing strong fixing force for the urn and ensuring the stability of the urn during processing.

[0026] Based on the above embodiments, the height of the suction cup is much higher than the height of the corresponding mounting surface on the glenoid cavity 222.

[0027] Based on the above embodiments, a micro-moving clamping part is movably provided on the periphery of the urn-shaped placement cavity 222. This movable micro-moving clamping part, combined with the negative pressure adsorption of the suction cup, fixes the urn from multiple directions. During processing, both axial and radial external forces can be effectively resisted, further enhancing the fixation effect of the urn within the placement cavity and greatly reducing the possibility of displacement of the urn during processing.

[0028] Based on the above embodiments, the arc-shaped adjustment part 211 is a protruding dovetail seat with a layer of grease applied to its surface. The design of the protruding dovetail seat with a grease coating on the surface of the arc-shaped adjustment part minimizes friction when adjusting the angle of the glenoid fossa. Operators can easily and accurately adjust the angle of the glenoid fossa without using complex auxiliary tools or applying significant external force, improving operational convenience and efficiency. Simultaneously, the presence of grease reduces wear between components and extends the service life of the tooling.

[0029] In use of this invention: First, adjust the angle of the glenoid fossa placement seat on the arc-shaped adjustment part of the support platform according to the processing requirements. Rotate the glenoid fossa placement seat around the arc-shaped adjustment part manually or with a simple adjustment tool. Since the arc-shaped adjustment part is coated with grease, angle adjustment is easy and precise. After adjusting to the appropriate angle, use fasteners (such as bolts) to firmly fix the glenoid fossa placement seat to the support platform. Place the glenoid fossa in the glenoid fossa contour placement cavity. At this time, activate the negative pressure system to generate negative pressure in the negative pressure airflow channel, causing the suction cup to tightly adhere to the glenoid fossa. Then, operate the micro-movement pressing part to further press the glenoid fossa from the periphery, ensuring that the glenoid fossa is completely fixed within the glenoid fossa contour placement cavity, preparing for subsequent processing. During the processing of the glenoid fossa (such as grinding, drilling, etc. using cutting tools), due to the stable positioning and fixation of the tooling, the glenoid fossa can maintain an accurate position and angle, allowing the processing tools to precisely process the glenoid fossa according to the preset processing path. During processing, the continuous suction of the suction cup and the pressing action of the micro-movement pressing part work together to maintain the fixed state of the glenoid fossa, ensuring processing accuracy. After a period of use, the tooling needs to be inspected and maintained. Check if the fasteners between the glenoid fossa and the support platform are loose, and retighten them if necessary. Check the suction performance of the suction cup; if the suction is insufficient, check if the negative pressure airflow channel is blocked and clean it. For the lubricating grease in the arc-shaped adjustment part, if wear or insufficient grease is found, replenish the grease promptly to ensure the normal angle adjustment function of the glenoid fossa. At the same time, check the movement flexibility and clamping effect of the micro-movement clamping part; adjust or repair it promptly if any problems are found.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art should be able to make equivalent embodiments by making some changes or modifications to the above-disclosed technical content without departing from the scope of the present invention.
