Description

Technical Field

[0001] This utility model relates to the field of titanium rod processing technology, specifically to a high-efficiency milling device for titanium rod processing. Background Technology

[0002] Titanium rods are bars made from pure titanium or titanium alloys (such as Ti-6Al-4V). Based on their composition, they can be divided into pure titanium rods and titanium alloy rods. Pure titanium rods, such as those conforming to Chinese national standards TA1-TA3 and American standards GR1-GR4, exhibit excellent corrosion resistance and biocompatibility, making them suitable for chemical and medical applications. Titanium alloy rods, such as TC4 (Ti-6Al-4V), have their strength enhanced by adding elements like aluminum and vanadium, and are primarily used in aerospace and other high-strength applications. To meet these requirements, titanium rods typically undergo milling and other machining processes.

[0003] For example, a titanium rod drilling device with publication number CN221473583U relates to the field of titanium rod drilling technology. It includes a titanium rod drilling mechanism, which comprises a fixed base, a worktable fixedly connected to the top of the fixed base, a first control panel mounted on one side of the worktable, a placement recess fixedly mounted on the surface of the worktable, a titanium rod body disposed on the top of the placement recess, two sets of top-holding limiting components fixedly mounted inside the worktable, each set of top-holding limiting components having a pressing limiting component fixedly mounted on its top, and a clamping limiting component fixedly mounted inside the worktable. This invention can place and fix titanium rods, facilitating stable limiting of the titanium rods, improving the fixing effect of the titanium rods, and enhancing the processing quality of the titanium rods. Simultaneously, it can also perform drilling operations on the titanium rods, improving drilling efficiency, saving processing time, and increasing work efficiency.

[0004] Although this type of technology can effectively limit the position of titanium rods, the limitation of the top holding groove means that it can only clamp and position titanium rods of a single specification. For some titanium rods with smaller diameters, the outer wall of one end of the titanium rod cannot fit against the inner wall of the top holding groove, and the pressure plate only makes line contact between the top of its inner wall and the outer wall of the titanium rod. As a result, the limiting and fixing effect on the titanium rod is poor, and the overall adaptability to titanium rods of different specifications is limited. Utility Model Content

[0019] 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.

[0020] Please see Figure 1-5 The present invention provides the following technical solution:

[0021] Example 1: A high-efficiency milling device for processing titanium bars includes a worktable 1, a mounting frame 2, a milling machine 3, a placement slot 4, two clamping blocks 7, two motors 23, two turntables 12, two first fixing columns 13, two fixing blocks 20, two guide plates 17, two top columns 19, two first connecting rods 14, four extrusion plates 21, and two clamping assemblies 8. The mounting frame 2 is fixed to the upper end of the worktable 1. The milling machine 3 is adjustablely mounted at the bottom end of the mounting frame 2 to process the titanium bars. The placement slot 4 is located at the upper end of the worktable 1 for placing the titanium bars. Hydraulic cylinders 5 are fixedly connected between the two clamping blocks 7 and the side walls of the placement slot 4 to clamp the titanium bars. The two motors 23 are respectively fixedly connected to the upper ends of the two clamping blocks 7 via two vertical plates 11. The two turntables 12 are respectively fixedly connected to the output ends of the two motors 23. The two first fixing columns 13 are respectively fixed to the upper ends of the two clamping blocks 7. Two turntables 12 are located on the outer side of two clamping blocks 7. Two fixed blocks 20 are located on one side of two clamping blocks 7 and are fixedly connected to guide blocks 18 at their upper ends. Two guide plates 17 are vertically fixed on the two clamping blocks 7 and are movably connected to the two guide blocks 18. Two top columns 19 are fixed at the center of the upper end of the two fixed blocks 20. The upper ends of the two first connecting rods 14 are rotatably connected to the two first fixed columns 13, and their bottom ends are rotatably connected to the two top columns 19. Four extrusion plates 21 are fixed on both sides of the bottom end of the two fixed blocks 20. Two clamping components 8 are located on one side of the two clamping blocks 7 and correspond to the four extrusion plates 21. The two clamping blocks 7 clamp the two ends of the titanium rod, and the first clamping plate 81 and the second clamping plate 82 clamp the two sides of the titanium rod, thereby ensuring the stability of the titanium rod during processing and adapting to titanium rods of different specifications, making it more adaptable.

[0022] Each clamping assembly 8 includes a first clamping plate 81, an opening 83, a second clamping plate 82, a rotating shaft 85, and two torsion springs 84. The first clamping plate 81 is located on one side of the clamping block 7; the opening 83 is opened on one side of the first clamping plate 81; one end of the second clamping plate 82 is movably inserted into the opening 83; the rotating shaft 85 is fixedly connected to the side wall of the clamping block 7 and rotatably connected to the first clamping plate 81 and the second clamping plate 82; the two torsion springs 84 are respectively fixed between the two sides of the second clamping plate 82 and the two side walls of the opening 83 and are sleeved around the rotating shaft 85. The first clamping plate 81 and the second clamping plate 82 are rotated along the rotating shaft 85. Finally, the first clamping plate 81 and the second clamping plate 82 will be tightly fitted with the two sides of the titanium rod, thereby clamping the titanium rod and further ensuring the stability of the titanium rod.

[0023] The bottom wall of the placement groove 4 is fixedly connected to the support plate 6. The support plate 6 is arc-shaped to initially position the titanium rod. The titanium rod is placed on the support plate 6. Since the support plate 6 is arc-shaped and the titanium rod is cylindrical, the titanium rod will be in the center of the support plate 6, which facilitates quick positioning of the titanium rod.

[0024] The bottom ends of the four extrusion plates 21 are all curved, and the bottom ends of the four extrusion plates 21 contact the upper ends of the two first clamping plates 81 and the two second clamping plates 82 respectively, so that the extrusion plates 21 can push the first clamping plates 81 and the second clamping plates 82 to flip.

[0025] In use, the titanium rod is placed on the support plate 6, and then the two hydraulic cylinders 5 are activated. The two hydraulic cylinders 5 push the two clamping blocks 7 to move towards each other, and the two clamping blocks 7 contact the two ends of the titanium rod to clamp the titanium rod. At this time, the motor 23 is activated, and the motor 23 drives the turntable 12 to rotate. When the turntable 12 rotates, the horizontal height of the first fixed column 13 goes from high to low. The first fixed column 13 pushes the fixed block 20 and the two extrusion plates 21 to move down steadily through the first connecting rod 14. When the two extrusion plates 21 move down, they push the first clamping plate 81 and the second clamping plate 82 to flip along the rotating shaft 85 and twist the torsion spring 84. The first clamping plate 81 and the second clamping plate 82 will eventually fit tightly against the two sides of the titanium rod, thereby clamping the titanium rod, further ensuring the stability of the titanium rod, and adapting to titanium rods of different specifications, making it more adaptable.

[0026] Example 2, the technical solution of which differs from Example 1 includes: each of the two clamping blocks 7 is provided with a through hole 9 at the center of the opposite side, each of the two through holes 9 is provided with a side groove 25 on the top wall, each of the two side grooves 25 is movably connected with a piston 24, each of the two pistons 24 is fixedly connected with a fixing rod 22 at the center of the upper end, the upper ends of the two fixing rods 22 are respectively movably sleeved with the two clamping blocks 7, each of the two side grooves 25 is provided with an air hole 26 between the outer side wall of the corresponding clamping block 7, a second fixing post 15 is fixedly connected to the outer side of the turntable 12, a second connecting rod 16 is provided between the top of the two fixing rods 22 and the second fixing post 15, the top of the second connecting rod 16 is rotatably connected to the second fixing post 15, and the bottom of the second connecting rod 16 is rotatably connected to the top of the fixing rod 22. By moving the piston 24 upward in the side groove 25, a negative pressure is generated in the through hole 9, and the stability of the titanium rod is further ensured by the force of the negative pressure.

[0027] Both through holes 9 are equipped with sealing rings 10 around their openings. The two sealing rings 10 are fixed to the outside of the two clamping blocks 7 to ensure sealing.

[0028] In use, the horizontal height of the second fixed column 15 will move from a low position to a high position through the rotation of the turntable 12. The second fixed column 15 will drive the fixed rod 22 to move upward through the second connecting rod 16. The fixed rod 22 will drive the piston 24 to move upward in the side groove 25. When the clamping block 7 is tightly attached to the end of the titanium rod, the end of the titanium rod will be tightly attached to the sealing ring 10 and the through hole 9. Therefore, when the piston 24 moves upward in the side groove 25, it will generate negative pressure in the through hole 9. The negative pressure will further ensure the stability of the titanium rod. Finally, the titanium rod will be processed by the milling equipment 3.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
