Description

Technical Field

[0001] This utility model relates to the field of workpiece processing and manufacturing technology, and in particular to a femoral condyle grinding and positioning fixture. Background Technology

[0002] In the field of orthopedic medical device manufacturing, femoral condyle grinding is a crucial process. As an important component of the human knee joint, the precision of the femoral condyle's shape and size directly affects the success of prosthesis or joint replacement surgery and the postoperative rehabilitation outcome for patients. Therefore, femoral condyle grinding requires not only high-precision equipment but also an efficient, stable, and easy-to-operate tooling system to ensure the smooth execution of the grinding process.

[0003] Traditional femoral condyle grinding fixture systems often suffer from several problems, such as inaccurate workpiece positioning, low transfer efficiency, and inconvenient fixture changes. These issues not only affect the precision and efficiency of grinding but also increase the labor intensity and safety risks for operators. Therefore, developing a new type of femoral condyle grinding placement and positioning fixture is of paramount importance. Utility Model Content

Multiple workpiece placement parts are arranged in parallel on the tray. The bottom of the tray is connected to the conveying device. The conveying device can drive the tray and workpiece placement parts to move with it. Multiple workpiece placement positions are provided on the workpiece placement part for placing workpieces.

[0007] Furthermore, the workpiece placement position is provided with 4 supporting protrusions to support the workpiece and 3 positioning protrusions to position the workpiece. The 4 supporting protrusions are located near the four corners of the workpiece placement position.

[0008] Furthermore, the workpiece placement section is detachably connected to the tray.

[0009] Furthermore, the workpiece placement section is provided with multiple through holes, through which screws can pass and fix the workpiece placement section to the tray.

[0024] The following is for reference. Figures 1 to 4 The present invention will be further described below:

[0025] The femoral condyle grinding and positioning fixture includes: a workpiece placement part 1, a tray 2, and a conveying device 3. Multiple workpiece placement parts 1 are arranged in parallel on the tray 2. The bottom of the tray 2 is connected to the conveying device 3. The conveying device 3 can drive the tray 2 and the workpiece placement parts 1 to move with it. Multiple workpiece placement positions 10 are provided on the workpiece placement part 1 for placing workpieces.

[0026] In a preferred embodiment, the tray 2 is made of sturdy metal to ensure load-bearing capacity and stability. The conveying device 3 is electrically driven. Before grinding, the operator places the workpieces to be ground one by one onto the tray 2. When grinding, the machine is started, and the conveying device 3 smoothly conveys the tray 2 and the workpiece placement part 1 on it from one end to the other. At this time, a mechanical clamping arm at the other end works in conjunction with the femoral condyle grinding placement and positioning fixture to pick up the workpiece to be ground from the workpiece placement part 1 for grinding. After grinding, the workpiece is placed back into the workpiece placement part 1, and then the next workpiece is picked up. This process is repeated until all the workpieces on the tray have been ground. At this time, the conveying device 3 will transport the workpieces back along the original path for the operator to collect. This achieves smooth operation and improves the efficiency of workpiece grinding.

[0027] In this embodiment, the workpiece placement position 10 is provided with four supporting protrusions 101 to support the workpiece and three positioning protrusions 102 to position the workpiece. The four supporting protrusions 101 are located near the four corners of the workpiece placement position 10. Their positions are precisely calculated to match specific parts of the femoral condyle. When fixing the workpiece, the corresponding part of the workpiece to be ground is placed on the workpiece placement position 10, corresponding to the positioning protrusions 102. At this time, the supporting protrusions 101 just support the workpiece, while the positioning protrusions 102 ensure that the workpiece will not move arbitrarily.

[0028] In actual production, the supporting protrusions 101 and positioning protrusions 102 on the workpiece placement position 10 can be set as needed, and their positions and quantities can be adjusted accordingly.

[0029] The workpiece placement section 1 is detachably connected to the tray 2.

[0030] In a preferred embodiment, the workpiece placement part 1 is provided with a plurality of through holes, through which screws can pass and fix the workpiece placement part 1 to the tray 2.

[0031] To meet the grinding needs of femoral condyle workpieces of different sizes and shapes, we designed a detachable workpiece placement section 1. This section features a standardized design, allowing for easy removal from the tray 2 and replacement with a model suitable for the current workpiece. Furthermore, the workpiece placement section 1 is secured to the tray 2 via screws and through holes, ensuring no shaking or displacement during grinding. This design makes the fixture more flexible and adaptable to different customer needs. These through holes match corresponding positions on the tray 2. During installation, simply pass the screws through the through holes and tighten them to securely fix the workpiece placement section 1 to the tray 2. This design not only facilitates the replacement of the workpiece placement section 1 but also ensures the overall stability and durability of the fixture.

[0032] When multiple workpiece placement parts 1 are arranged in parallel, the directions of two adjacent workpiece placement parts 1 are opposite. This design can satisfy the requirement that two femoral condyle workpieces with different orientations can be placed on one tray during grinding, thus improving grinding efficiency.

[0033] Furthermore, there are two conveying devices 3, which are arranged adjacent to each other. Each conveying device 3 has a workpiece placement part 1 and a tray 2 above it.

[0034] In a preferred embodiment, a dual-transfer device (3) design is adopted to improve production efficiency and flexibility. Two transfer devices 3 are arranged adjacent to each other, with a workpiece placement section 1 and a tray 2 above each device 3. This design allows for the loading and initial positioning of the femoral condyle on one transfer device 3, while grinding operations are performed on the other. After grinding of the workpiece on one tray 2 is completed, grinding of the workpiece on the next tray 2 can begin immediately. The two transfer devices 3 are synchronized and coordinated through a control system to ensure the stability and accuracy of the workpiece during transport. This dual-transfer device design not only improves production efficiency but also makes the entire production line more flexible and efficient.

[0035] In a preferred embodiment, the tray 2 is detachably connected to the conveying device 3.

[0036] The bottom of pallet 2 features a standardized connection interface that matches the corresponding interface on the conveyor 3. During installation, simply align and secure the connection interface on the bottom of pallet 2 with the interface on the conveyor 3 to connect the pallet to the conveyor. This design not only facilitates the replacement and maintenance of pallet 2 but also makes the entire tooling system more flexible and customizable. Furthermore, the detachable connection method allows for adjustments to the number and layout of pallets 2 according to production needs, adapting to different scales and types of production tasks.
