Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to a high-efficiency fixture for milling the flash of medical joints. Background Technology

[0002] A jig is a device used in mechanical manufacturing to fix the workpiece in the correct position for construction or inspection. In the forging process of medical joints, excess material from the blank will flow out from the burr groove of the mold and form burrs. After the medical joint is forged, a jig is needed to hold and fix the medical joint, and then the burrs of the medical joint are removed by milling.

[0003] The published patent document CN218051417U discloses a high-efficiency jig for milling the flash of medical joints. This published patent document improves the efficiency of milling the flash of medical joints by optimizing the jig structure. The clamping structure is compact, and the clamping of medical joints is stable and reliable. It also improves the milling accuracy of the flash of medical joints and reduces the scrap rate and production cost. However, different medical joints have different lengths and different degrees of bending. In the above-mentioned published patent document, the medical joint must be adapted to the positioning groove for clamping and fixing, which limits the scope of application. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency fixture for milling the flash of medical joints, which solves the problems mentioned in the background art.

[0005] This application provides a high-efficiency fixture for milling the flash of a medical joint, including a disc body. A rotating shaft is rotatably mounted through the middle of the disc body. Several L-shaped rods are fixedly connected at equal intervals to the outer wall of the upper part of the rotating shaft. A fixture plate is fixedly mounted on the side of the L-shaped rods away from the rotating shaft. A medical joint is provided in front of the fixture plate, and several sliding grooves are equally spaced on the front side of the fixture plate. Two sliders are vertically slidably connected inside each sliding groove. A fixed shaft is fixedly mounted on the front side of the slider, and a bakelite bolt passes through the slider. The bakelite bolt is threadedly connected to the slider, and the rear end of the bakelite bolt contacts and abuts against the rear inner wall of the sliding groove.

[0006] By adopting the above technical solution, the medical joint is placed between every two vertical fixed axes, and each slider is slid vertically along the slide groove to make the upper and lower fixed axes contact the medical joint. Then, the bakelite bolts are rotated so that their rear ends contact and abut against the inner wall of the rear side of the slide groove, thereby clamping and fixing the medical joint. This increases the accuracy of flash milling, and the position of each fixed axis can be adjusted according to the different bending degrees of the medical joint, thus making it suitable for different medical joints.

[0007] Optionally, a drive motor is fixedly installed at the bottom of the disc, a small spur gear is fixedly installed at the output end of the drive motor, and a large spur gear is fixedly installed at the lower end of the rotating shaft. The large spur gear meshes with the small spur gear, and the diameter of the large spur gear is larger than the diameter of the small spur gear.

[0008] By adopting the above technical solution, the drive motor drives the small spur gear to rotate. Due to the meshing connection between the large spur gear and the small spur gear, the rotating shaft can be driven to decelerate and rotate. This allows each fixture plate and medical joint to be easily rotated to the flash milling processing area without changing the processing position.

[0009] Optionally, a cleaning scraper matching the disc body is fixedly installed on the outer wall of the rotating shaft. The cleaning scraper is located inside the disc body and contacts the inner wall of the disc body. A cleaning hole is provided on the disc body, and a collection box is fixedly installed below the disc body, with the collection box located below the cleaning hole.

[0010] By adopting the above technical solution, the cleaning scraper rotates along the inner wall of the disc during the rotation of the shaft, which can clean the waste material from the flash milling to the cleaning hole and finally fall into the collection box.

[0011] Optionally, a matching rubber sleeve is fitted and fixedly connected to the fixed shaft.

[0012] By adopting the above technical solution, the pressure between the fixed axis and the medical joint is reduced, thereby protecting the medical joint during the clamping and fixation process.

[0013] Optionally, four internally threaded sleeves are fixedly connected at equal intervals along the outer edge of the bottom of the disc body. The lower inner side of each internally threaded sleeve is threaded with a matching threaded shaft, and a foot pad is fixedly installed at the lower end of the threaded shaft.

[0014] By adopting the above technical solution, the position of the rotating threaded shaft within the internal threaded sleeve is adjusted, thereby adjusting the height of each foot pad to suit uneven work surfaces.

[0015] Optionally, the bottom of the foot pad is provided with anti-slip texture.

[0016] By adopting the above technical solution, the stability of the fixture placement is increased.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] The technical solution of this application places the medical joint between every two vertical fixed axes, rotates the bakelite bolts to release their contact with the slide groove, and then slides each slider vertically along the slide groove to make the upper and lower fixed axes contact the medical joint. Then, rotates the bakelite bolts so that their rear ends contact and abut against the inner rear wall of the slide groove to fix the sliders. This clamps and fixes the medical joint, thereby increasing the accuracy of flash milling. The position of each fixed axis can be adjusted according to the different bending degrees of the medical joint, thus making it suitable for different medical joints and having a wide range of applications.

[0019] The technical solution of this application uses a drive motor to rotate a small spur gear. Due to the meshing connection between the large and small spur gears, the rotating shaft can be driven to decelerate and rotate. This allows for the convenient rotation of various fixture plates and medical joints to the flash milling area without changing the machining position, increasing work efficiency. During the rotation of the rotating shaft, the cleaning scraper rotates along the inner wall of the disc, which can clean the flash milling waste to the cleaning hole and finally drop it into the collection box, increasing the convenience of waste collection.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Please see Figure 1-3This utility model provides a high-efficiency jig for milling the flash of medical joints, including a disc body 1. A rotating shaft 2 is rotatably mounted through the middle of the disc body 1. Several L-shaped rods 3 are fixedly connected at equal intervals on the outer wall of the upper part of the rotating shaft 2. A jig plate 4 is fixedly mounted on the side of the L-shaped rods 3 away from the rotating shaft 2. A medical joint 5 is provided in front of the jig plate 4. Several sliding grooves 15 are opened at equal intervals on the front side of the jig plate 4. Two sliders 16 are vertically slidably connected inside each sliding groove 15. A fixed shaft 17 is fixedly mounted on the front side of the slider 16. A bakelite bolt 18 passes through the slider 16. The bakelite bolt 18 is connected to the slider 16 by a thread, and the rear end of the bakelite bolt 18 contacts and abuts against the rear inner wall of the sliding groove 15.

[0027] In this technical solution, the medical joint 5 is placed between every two vertical fixed shafts 17. The bakelite bolts 18 are rotated to release their contact with the slide grooves 15. Then, each slider 16 is slid vertically along the slide grooves 15 to make the upper and lower fixed shafts 17 contact the medical joint 5. The bakelite bolts 18 are then rotated so that their rear ends contact and abut against the rear inner wall of the slide grooves 15 to fix the sliders 16. This clamps and fixes the medical joint 5, thereby increasing the accuracy of flash milling. The position of each fixed shaft 17 can be adjusted according to the different bending degrees of the medical joint 5, making it suitable for different medical joints 5 and having a wide range of applications.

[0028] In some technical solutions, such as Figure 2 As shown, a drive motor 11 is fixedly installed at the bottom of the disc body 1, a small spur gear 12 is fixedly installed at the output end of the drive motor 11, and a large spur gear 13 is fixedly installed at the lower end of the rotating shaft 2. The large spur gear 13 meshes with the small spur gear 12, and the diameter of the large spur gear 13 is larger than the diameter of the small spur gear 12.

[0029] In use, the drive motor 11 drives the small spur gear 12 to rotate. Due to the meshing connection between the large spur gear 13 and the small spur gear 12, the rotating shaft 2 can be driven to rotate at a reduced speed. This allows each fixture plate 4 and medical joint 5 to be easily rotated to the flash milling processing area without changing the processing position, thus increasing work efficiency.

[0030] In some technical solutions, such as Figure 1-2 As shown, a cleaning scraper 6 matching the disc body 1 is fixedly installed on the outer wall of the rotating shaft 2. The cleaning scraper 6 is located inside the disc body 1 and contacts the inner wall of the disc body 1. A cleaning hole 14 is provided on the disc body 1, and a collection box 7 is fixedly installed below the disc body 1. The collection box 7 is located below the cleaning hole 14.

[0031] During use, as the rotating shaft 2 rotates, the cleaning scraper 6 rotates along the inner wall of the disc 1, which can clean the waste material from the flash milling to the cleaning hole 14, and finally fall into the collection box 7, increasing the convenience of collecting waste material.

[0032] In some technical solutions, such as Figure 3 As shown, a matching rubber sleeve 19 is fitted and fixedly connected to the fixed shaft 17.

[0033] In use, the rubber sleeve 19 reduces the pressure between the fixed shaft 17 and the medical joint 5, thereby protecting the medical joint 5 during the clamping and fixing process.

[0034] In some technical solutions, such as Figure 1-2 As shown, four internally threaded sleeves 8 are fixedly connected at equal intervals along the outer edge of the bottom of the disc body 1. The lower inner side of the internally threaded sleeves 8 is connected to a matching threaded shaft 9, and a foot pad 10 is fixedly installed at the lower end of the threaded shaft 9.

[0035] In use, the position of the threaded shaft 9 within the internal threaded sleeve 8 is adjusted by rotating the threaded shaft 9, thereby adjusting the height of each foot pad 10 to suit uneven work surfaces.

[0036] In some technical solutions, such as Figure 2 As shown, the bottom of the foot pad 10 is provided with anti-slip texture.

[0037] When in use, the anti-slip texture on the bottom of the foot pad 10 increases the stability of the clamp.

[0038] Working principle: During use, the fixture is first placed in the flash milling area. Then, the medical joint 5 is placed between every two vertical fixed shafts 17. The bakelite bolts 18 are rotated to release their contact with the slide grooves 15. Next, each slider 16 is slid vertically along the slide grooves 15 until the upper and lower fixed shafts 17 contact the medical joint 5. Then, the bakelite bolts 18 are rotated so that their rear ends contact and abut against the rear inner wall of the slide groove 15, thus fixing the sliders 16. This clamps and fixes the medical joint 5, increasing the accuracy of flash milling. Furthermore, the fixture can be adjusted according to the different characteristics of the medical joint 5. The bending degree adjustment of each fixed shaft 17 has a wide range of applications. The drive motor 11 drives the small spur gear 12 to rotate. Due to the meshing connection between the large spur gear 13 and the small spur gear 12, the rotating shaft 2 can be driven to decelerate and rotate. This allows each clamping plate 4 and medical joint 5 to be easily rotated to the flash milling processing area without changing the processing position. During the rotation of the rotating shaft 2, the cleaning scraper 6 rotates along the inner wall of the disc 1, which can clean the flash milling waste to the cleaning hole 14 and finally drop it into the collection box 7.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application 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 this application should be included within the protection scope of this application.
