Description

Technical Field

[0001] This utility model relates to the field of fracture external fixation plate production technology, and in particular to a production device for a fracture external fixation plate made of a new material. Background Technology

[0002] Currently, in clinical practice, fracture fixation usually involves first reducing the fracture site and then applying a splint for external fixation. The production of fracture external fixation plates involves multiple stages, including material selection, manufacturing processes, and quality control. Different materials used in fracture external fixation plates offer different medical effects and require different manufacturing processes. For example, low-temperature thermoplastic plates are characterized by high plasticity, good breathability, light weight, high strength, non-toxicity, odorlessness, non-irritating to the skin, good radiation permeability, and ease of use. They are mainly used in the fabrication of orthopedic external fixation devices, orthotics, and braces. After shaping, low-temperature thermoplastic plates require grinding to remove surface burrs and ensure a better fit to the patient's body shape.

[0003] The thermoplastic sheet grinding device with a protective structure, as described in announcement number CN220613330U, includes a worktable. Multiple support columns are fixedly mounted on the top of the worktable, and a single top plate is fixedly mounted on the top of each support column. This invention utilizes components such as an outer protective cover, a storage slot, a first spring, a telescopic cover, an observation window, a limiting strip, a slot, an insert plate, and second springs. During grinding, the insert plate is pulled out to one side. After one side of the insert plate disengages from the slot, multiple first springs apply a pushing force to the telescopic cover, causing it to move upwards. When the telescopic cover reaches the appropriate position, the insert plate is released, and under the tension of two second springs, the insert plate re-inserts into the slot, thus positioning the telescopic cover. The device is then started for grinding. The telescopic cover effectively blocks flying debris generated during grinding, preventing injury to the worker's skin and improving equipment safety.

[0004] Based on the above technical features, the problem is that existing thermoplastic sheet grinding devices easily generate dust when grinding thermoplastic sheets. During the grinding process, the dust can easily escape from the protective cover into the outside air, thereby polluting the air, being inhaled by people, and causing harm to production personnel.

[0005] Therefore, it is necessary to solve the above problems by using a production device for fracture external fixation plates made of a new material. Utility Model Content

[0021] A mounting frame 2 is welded to the top of the workbench 1. The mounting frame 2 consists of a horizontal top plate and four vertical support rods. The four support rods are arranged in a matrix between the top plate and the workbench 1. The four support rods are fixedly connected to the top plate and the workbench 1.

[0022] Four hydraulic cylinders 3 arranged in a matrix are fixedly installed on the top plate of the mounting frame 2. The telescopic shafts of the four hydraulic cylinders 3 are all vertically downward and fixedly connected to the same horizontal support plate 6. The lower part of the support plate 6 is fixedly connected to the protective cover 8 through a vertical connecting rod. The protective cover 8 is disc-shaped and abuts against the fracture external fixation plate of the new material.

[0023] The protective cover 8 has a downward-facing circular groove coaxially formed inside, and a coarse grinding disc 10 and a fine grinding disc 22 are coaxially arranged inside the groove. A power mechanism is installed on the support plate 6, and the power mechanism is connected to the coarse grinding disc 10 and the fine grinding disc 22.

[0024] The power mechanism includes a first power component and a second power component. The first power component is driven by a coarse grinding disc 10 to drive its rotation.

The coarse grinding disc 10 is mounted on the fine grinding disc 22, and the coarse grinding disc 10 and the fine grinding disc 22 are in a driving engagement to drive the fine grinding disc 22 to rotate.

[0025] The first power assembly includes a second motor 15 and a first rotating tube 17. The first rotating tube 17 passes vertically through the support plate 6 and the protective cover 8, and is rotatably connected to both. The second motor 15 is bolted to the top of the support plate 6. The output shaft of the second motor 15 passes downward through the support plate 6, and a first gear 7 is fixedly sleeved on the output shaft of the second motor 15.

[0027] The second power assembly includes a first motor 11 and a second rotating tube 21.

[0028] A sleeve 20 is fitted onto the second rotating tube 21. The sleeve 20 is threadedly connected to the second rotating tube 21, and the bottom end of the sleeve 20 extends out of the first rotating tube 17. At the same time, the fine grinding disc 22 is fixedly fitted onto the bottom end of the sleeve 20.

[0029] Several transmission blocks are fixedly installed on the outer wall of the sleeve 20, and the transmission blocks are evenly distributed along the circumference of the sleeve 20. A transmission groove corresponding to the transmission block is opened along the axial direction on the inner wall of the first rotating tube 17. Each transmission block has both a limiting sliding fit and an abutting transmission fit with the corresponding transmission groove.

[0030] The protective cover 8 has a downward-facing annular groove along its circumference inside its shell. An annular pressure block 9 is slidably installed within this groove, abutting against the new material fracture external fixation plate. Multiple vertically positioned sliding rods 19 are welded to the top of the pressure block 9, evenly distributed along its circumference. Each sliding rod 19 extends upwards through the protective cover 8. Each sliding rod 19 is slidably connected to the protective cover 8, and a limit cap is welded to the top of each sliding rod 19.

[0031] Each slide bar 19 is fitted with a spring 16, the top of each spring 16 is fixedly connected to the protective cover 8, and the bottom of each spring 16 is fixedly connected to the pressure block 9.

[0032] Multiple protective pads are fixedly installed at the bottom of the pressure block 9, and the multiple protective pads are evenly distributed along the circumference of the pressure block 9.

[0033] A vacuum cleaner 5 is fixedly installed on the top of the support plate 6, and the suction port of the vacuum cleaner 5 is fixedly connected to the suction pipe 4. The suction pipe 4 is coaxially inserted into the second rotating pipe 21 and passes through the fine grinding disc 22. The suction pipe 4 is inverted trumpet-shaped at the opening away from the vacuum cleaner 5, and the suction pipe 4 is rotatably connected to the second rotating pipe 21.

[0034] Multiple arc-shaped guide grooves are opened on both the coarse grinding disc 10 and the fine grinding disc 22. The multiple guide grooves on the coarse grinding disc 10 and the multiple guide grooves on the fine grinding disc 22 are evenly distributed along the circumference of the second rotating pipe 21.

[0035] Working principle: When grinding a new external fixation plate made of fracture material is required, the plate is placed on the workbench 1, directly below the protective cover 8. Then, four hydraulic cylinders 3 are simultaneously activated, their telescopic axes extending downwards in sync, moving the support plate 6 downwards. The support plate 6 moves the protective cover 8 downwards towards the new external fixation plate, and the protective cover 8, via spring 16, pushes the pressure block 9 downwards towards the plate.

[0036] When the pressure block 9 comes into contact with the new material fracture external fixation plate, the pressure block 9 stops moving, and at this time the protective cover 8 compresses all the springs 16. As the protective cover 8 continues to move downward, the pressure block 9 presses the new material fracture external fixation plate tighter and tighter. When the coarse grinding disc 10 comes into contact with and abuts against the new material fracture external fixation plate, the four hydraulic cylinders 3 are shut down.

[0037] At this time, the second motor 15 is started, and the output shaft of the second motor 15 drives the first gear 7 to rotate. The first gear 7 drives the fourth gear 18 to rotate, and the fourth gear 18 drives the first rotating tube 17 to rotate. The first rotating tube 17 drives the coarse grinding disc 10 to coarsely grind the new material fracture external fixation plate. Before this, the vacuum cleaner 5 is started, and the vacuum cleaner 5 sucks away the dust generated during the coarse grinding process through the suction pipe 4. During this process, the dust generated by the coarse grinding disc 10 is sucked into the suction pipe 4 through the guide channel.

[0038] After the coarse grinding is completed, the second motor 15 is turned off. In this embodiment, both the first motor 11 and the second motor 15 are equipped with a brake device. Then, the four hydraulic cylinders 3 are restarted, and their extension axes retract synchronously upwards. At this time, the support plate 6 moves the protective cover 8 away from the new material fracture fixation plate, and all springs 16 extend. When all springs 16 return to their natural length, the protective cover 8 pulls the pressure block 9 away from the new material fracture fixation plate through the springs 16 until it is reset.

[0039] After the support plate 6 returns to its pre-grinding position, the four hydraulic cylinders 3 are shut down. Then, the new material fracture fixation plate is pushed so that the coarse grinding position aligns with the fine grinding disc 22. Next, the first motor 11 is started, and its output shaft drives the second gear 12 to rotate. The second gear 12 drives the third gear 13 to rotate, and the third gear 13 drives the inner ring of the one-way bearing 14 to rotate synchronously. The inner ring of the one-way bearing 14 drives the second rotating tube 21 to rotate, and during this rotation, the sleeve 20 slides down, causing the fine grinding disc 22 to slide downwards from the coarse grinding disc 10. During this process, because the second motor 15 has a brake device, its output shaft remains stationary, and the first gear 7, the fourth gear 18, and the first rotating tube 17 also remain stationary.

[0040] When the surface of the fine grinding disc 22 used for grinding has completely slid out from the coarse grinding disc 10, the first motor 11 is shut off, and the four hydraulic cylinders 3 are restarted, with their telescopic shafts extending downwards again. After the pressure block 9 contacts the new material fracture fixation plate, the protective cover 8 compresses the spring 16 again. Then, after the fine grinding disc 22 contacts the grinding position, the four hydraulic cylinders 3 are shut off, and the second motor 15 is restarted.

[0041] Subsequently, the first rotating tube 17 drives the transmission block to revolve around the central axis of the second rotating tube 21 via the transmission groove. The transmission block drives the sleeve 20 to rotate, and the sleeve 20 drives the fine grinding disc 22 to perform fine grinding on the grinding position. The dust generated during the fine grinding process is sucked into the suction pipe 4 through the guide groove, and finally sucked into the vacuum cleaner 5 through the suction pipe 4. In this example, the suction pipe 4 is a rigid pipe.

[0042] When the sleeve 20 rotates, it drives the second rotating tube 21 to rotate synchronously because it is threadedly connected to the second rotating tube 21. The second rotating tube 21 then drives the inner ring of the one-way bearing 14 to rotate freely. During this process, because the first motor 11 is equipped with a brake device, the second gear 12, the third gear 13, and the outer ring of the one-way bearing 14 are all stationary.

[0043] After fine grinding is completed, turn off the second motor 15, and the telescopic axes of the four hydraulic cylinders 3 will retract upwards.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
