Description

Technical Field

[0001] This utility model relates to the technical field of prosthesis grinding, specifically to a carbon fiber prosthesis grinding clamping device. Background Technology

[0002] A prosthesis is an artificial prosthesis used to compensate for amputation or limb incompleteness. During its use, the prosthesis needs to be ground according to the patient's leg shape before it can be used by the patient. Existing prosthesis grinding equipment basically uses robotic arms for intelligent grinding. However, since the connection of the prosthesis is in direct contact with the patient's skin during use, the grinding of the inside of the prosthesis is also very important.

[0003] However, since prostheses are installed vertically during the polishing process, the free end of the robotic arm needs to be kept vertical in order to insert the polishing tool into the prosthesis to complete the polishing work. In order to improve polishing efficiency, existing polishing devices usually install two robotic arms to polish multiple prostheses at the same time. When the two robotic arms are vertical at the same time, their two free ends are prone to unnecessary interference, which affects the polishing process. Utility Model Content

[0004] To address the aforementioned problem of interference that can easily occur when the free ends of two robotic arms in the same grinding device simultaneously grind the inside of a prosthesis vertically, this invention proposes a carbon fiber prosthesis grinding and clamping device. The device includes a base with two mounting plates rotatably connected to it. The two mounting plates are arranged opposite each other. A driving device is located below each mounting plate, driving the two mounting plates to open and close simultaneously. A tensioning mechanism is provided on each mounting plate, and a workpiece to be processed is mounted on the tensioning mechanism. Robotic arms for grinding the workpiece are respectively located on both sides of the base.

[0005] A further feature of this invention is that: the upper surface of the base is provided with two mounting portions, and two mounting plates are rotatably connected to the two mounting portions respectively; a connecting rod is fixedly connected to the lower surface of the mounting plate, the connecting rod is bent, and a guide post is provided at the end of the connecting rod away from the mounting plate; a transmission plate is also included, and a sliding groove is provided on the transmission plate, and the two guide posts are slidably connected in the sliding groove; the output end of the driving device is fixedly connected to the transmission plate to drive the transmission plate to move up and down.

[0006] A further feature of this invention is that the tensioning mechanism includes a base plate, which is rotatably connected to the mounting plate. A servo motor is mounted on the bottom of the mounting plate corresponding to the base plate. The output end of the servo motor is fixedly connected to the base plate to drive the base plate to rotate. A connector is mounted on the base plate, and the workpiece is inserted into the connector.

[0007] A further feature of this invention is that three tensioning strips are provided at equal angles inside the insertion tube, and a rubber pad is also provided on the inner wall of the insertion tube, with the workpiece inserted between the tensioning strips and the rubber pad.

[0008] A further feature of this invention is that the tensioning strip is made of elastic metal.

[0009] A further feature of this invention is that the tensioning strip is wider at the top and narrower at the bottom.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. Through the cooperation of the drive device and the transmission plate, it is possible to simultaneously drive two mounting plates to open and close, thereby tilting the workpiece mounted on them at a certain angle. When two robotic arms need to grind the inside of the workpiece at the same time, the drive device can drive the two mounting plates to tilt, thereby tilting the workpiece. At this time, the robotic arms only need to maintain the same tilt angle as the workpiece to realize the process step of inserting the grinding tool into the inside of the workpiece for grinding, thus avoiding interference caused by the two robotic arms simultaneously raising the grinding tool.

[0012] 2. By setting a tensioning mechanism, not only can the purpose of installing and fixing the workpiece be achieved, but the process of installing and disassembling the workpiece on the clamping device can also be made simpler. That is, the workpiece only needs to be inserted into the insertion tube to achieve installation, and the disassembly process only needs to apply a certain pulling force to the workpiece.

[0020] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] refer to Figure 1-6 This utility model proposes a carbon fiber prosthesis grinding and clamping device, including a base 1. Two mounting parts 11 are fixedly connected to the base 1, and the two mounting parts 11 are respectively arranged on the two long sides of a base plate. Mounting plates 2 are rotatably connected to the mounting parts 11. The two mounting plates 2 can be opened apart. A driving device 3 is arranged below the mounting plates 2. The driving device 3 is a cylinder, which is used to simultaneously push the two mounting plates 2 to rotate, thereby enabling the two mounting plates 2 to open apart.

[0022] A tensioning mechanism 4 is also provided on the upper surface of the mounting plate 2. The tensioning mechanism 4 is used to install the workpiece 5 to be processed.

[0023] It should be noted that robotic arms are provided on both sides of the clamping device. The two robotic arms are used to grind the workpiece 5 on the corresponding mounting plate 2. It should also be noted that each mounting plate 2 is provided with two tensioning mechanisms 4.

[0024] A connecting rod 21 is welded to the lower surface of the mounting plate 2. The connecting rod 21 is bent, with both connecting rods 21 bent inwards. A guide post 211 is integrally provided at the end of the connecting rod 21 away from the mounting plate 2. A transmission plate 31 is also included, with a horizontal groove on it. Both guide posts 211 are slidably connected within the groove. That is, when the transmission plate 31 moves up and down, it can drive the mounting plate 2 to rotate via the guide posts 211 and the connecting rod 21, thus simultaneously driving both mounting plates 2 to open and close.

[0025] The bottom of the drive device 3 is fixedly connected to the base 1, and the output end of the drive device 3 is fixedly connected to the transmission plate 31. The drive device 3 can drive the transmission plate 31 to move up and down. It should also be noted that the two mounting parts 11 are provided with clearance grooves 111 corresponding to the connecting rod 21 and the transmission plate 31. The transmission plate 31 and the connecting rod 21 can move within the clearance grooves 111, thereby avoiding interference with the mounting parts 11.

[0026] The tensioning mechanism 4 includes a base plate 41, which is a circular plate. The base plate 41 is rotatably connected to the mounting plate 2. A servo motor 6 is mounted on the bottom of the mounting plate 2 corresponding to the base plate 41. The output end of the servo motor 6 passes through the mounting plate 2 and is fixedly connected to the base plate 41, thereby enabling the servo motor 6 to drive the mounting plate 2 to rotate.

[0027] A connector 42 is coaxially mounted on the base plate 41. The bottom end of the connector 42 is welded to the base plate 41. Three tensioning bars 43 are installed inside the connector 42. The bottom of the three tensioning bars 43 is also welded to the base plate 41. The three tensioning bars 43 are arranged at equal angles. The tensioning bars 43 are made of elastic metal and are designed to be wider at the top and narrower at the bottom.

[0028] Because elastic metal has a certain degree of elasticity, when the workpiece 5 is fitted onto the outside of the tensioning strips 43, the three tensioning strips 43 can generate tension force. The wider upper section and narrower lower section design makes it easier to fit the workpiece 5 onto the outside of the tensioning strips 43 during installation. A rubber pad 44 is also fixedly connected to the inner wall of the insertion pipe 42.

[0029] In use, the metal tube at the bottom of workpiece 5 is first inserted into the insertion tube 42. The metal tube is then fitted onto the three tensioning strips 43. The tensioning strips 43 generate tension within the metal tube, thus limiting its position. Simultaneously, the outer edge of the metal tube contacts the rubber pad 44, compressing it and causing elastic deformation, further limiting the metal tube's position. Once workpiece 5 is fixed, the robotic arm first grinds its outer surface. The servo motor 6 drives workpiece 5 to rotate, allowing for comprehensive grinding of its outer surface.

[0030] When it is necessary to grind the inside of the workpiece 5, the two mounting plates 2 can be driven by the drive device 3 to rotate in opposite directions, thereby tilting the workpiece 5 at a certain angle. Then, the free end of the robotic arm can be moved to a position with the same inclination as the workpiece 5, so that the grinding tool can be inserted into the inside of the workpiece 5 to complete the grinding process inside the workpiece 5.

[0031] In summary, this utility model, through the cooperation of the drive device 3 and the transmission plate 31, can simultaneously drive the two mounting plates 2 to open and close, thereby tilting the workpiece 5 mounted on them at a certain angle. When the two robotic arms need to grind the inside of the workpiece 5 at the same time, the drive device 3 can drive the two mounting plates 2 to tilt, thereby tilting the workpiece 5. At this time, the robotic arms only need to maintain an inclination angle with the same slope as the workpiece 5 to realize the process step of inserting the grinding tool into the inside of the workpiece 5 for grinding, thus avoiding interference caused by the two robotic arms simultaneously raising the grinding tool.

[0032] By setting the tensioning mechanism 4, not only can the installation and fixing of the workpiece 5 be achieved, but the installation and disassembly process of the workpiece 5 on the clamping device can also be made simpler. That is, the workpiece 5 only needs to be inserted into the insertion tube 42 to achieve installation, and the disassembly process only needs to apply a certain pulling force to the workpiece 5.
