Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and in particular to an aluminum profile milling fixture. Background Technology

[0002] In the machining of aluminum profiles, the milling process places extremely high demands on clamping stability. The main reasons can be summarized in three aspects: First, aluminum has relatively low hardness and good ductility. Unstable clamping can easily cause material vibration or displacement, leading to hole diameter deviation, excessive internal wall roughness, and even tool damage. Especially during deep hole machining, unstable clamping can cause the profile to undergo elastic deformation under radial cutting forces, resulting in out-of-tolerance hole position accuracy, and in severe cases, tool breakage. Second, modern CNC milling typically employs high-speed cutting processes, with spindle speeds generally reaching 8000-12000 r / min. At this speed, any minute vibration will be amplified into high-frequency chatter by the tool, not only leaving chatter marks on the hole wall affecting assembly accuracy but also significantly shortening tool life. However, aluminum profiles on the market have different cross-sectional dimensions, and currently used aluminum profile clamps lack versatility and cannot effectively clamp aluminum profiles with various cross-sectional dimensions. Utility Model Content

[0003] In view of this, the present invention aims to provide a milling fixture for aluminum profiles to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0004] The technical solution of this utility model embodiment is implemented as follows: an aluminum profile milling fixture includes a clamping rod one and a clamping rod two for clamping the workpiece. One end of the clamping rod one and the clamping rod two is rotatably connected to a clamping drive assembly. An assembly rod is inserted into one side of the clamping rod one and the clamping rod two, and an anti-slip plate is inserted into the other end of the assembly rod.

[0005] In some embodiments, one end of the clamping rod 1, the clamping rod 2, and the assembly rod are respectively fixedly connected with an anti-detachment plate, and an anti-detachment groove is opened on one side of the anti-detachment plate and the assembly rod, and the anti-detachment plate can be inserted into the anti-detachment groove.

[0006] In some embodiments, the clamping rod one, clamping rod two, assembly rod and anti-slip plate are respectively provided with mounting screw holes, and the mounting screw holes at one end of clamping rod one and clamping rod two are internally threaded with assembly screw two, and the mounting screw holes at one end of assembly rod and anti-slip plate are internally threaded with assembly screw one.

[0007] In some embodiments, the clamping drive assembly includes a rotating shaft, a turntable, and multiple connecting rods. The turntable is fixedly connected to the rotating shaft, and one end of each of the multiple connecting rods is rotatably connected to one side of the turntable. One end of clamping rod one and clamping rod two are respectively rotatably connected to the connecting rods.

[0008] In some embodiments, clamping boxes are rotatably connected to both ends of the rotating shaft, and multiple translation slots are opened on one side of the clamping box. Clamping rod one and clamping rod two are slidably connected to the inner side of the corresponding translation slots.

[0009] In some embodiments, a worm gear is fixedly connected to one side of the rotating shaft, a worm is rotatably connected to the inside of the clamping box, and a drive shaft is fixedly connected to the other end of the worm. The worm and the worm gear mesh with each other.

[0010] In some embodiments, one end of the clamping box is rotatably connected to a rotary joint, the other end of the rotary joint is rotatably connected to a sliding bracket, and a support plate is fixedly connected to one side of the sliding bracket.

[0011] In some embodiments, mounting plates are slidably connected below the two sliding brackets, and positioning bolts are threadedly connected to one side of the sliding brackets.

[0012] The present invention has the following advantages due to the adoption of the above technical solution:

[0013] 1. Aluminum profile milling fixture: The turntable drives the connecting rod to move clamping rod one and clamping rod two synchronously, realizing automatic clamping of standard aluminum profiles; for non-standard profiles, assembly rods and anti-slip plates can be added for expansion, and the anti-detachment plate and anti-detachment groove are used to prevent loosening, adapting to the fixing needs of processing parts with different cross-sectional dimensions.

[0014] 2. The aluminum profile milling fixture uses a worm gear drive to drive the clamping mechanism. The torque input through the drive shaft achieves self-locking, preventing the clamping from loosening due to processing vibration. At the same time, assembly screw one and assembly screw two respectively fasten the extension component to the main structure, enhancing the overall rigidity and reducing displacement errors during milling.

[0015] 3. Aluminum profile milling fixture: The clamping box can rotate the workpiece through the rotary joint. With the position adjustment of the sliding bracket on the mounting plate, it can achieve fixation in multiple postures such as horizontal and vertical. After the positioning bolt locks the bracket position, the support plate provides auxiliary support to ensure the stability of large-sized workpieces during processing.

In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Example 1:

[0028] like Figure 1-5As shown, the aluminum profile milling fixture includes a clamping rod 8 and a clamping rod 9 for clamping the workpiece 2. The clamping rod 8 and the clamping rod 9 are "T" shaped, and the "T" shaped crossbar portions of the clamping rod 8 and the clamping rod 9 are not in the same plane. One end of the clamping rod 8 and the clamping rod 9 is rotatably connected to a clamping drive assembly. An assembly rod 11 is inserted into one side of the clamping rod 8 and the clamping rod 9, and an anti-slip plate 12 is inserted into the other end of the assembly rod 11.

[0029] The clamping drive assembly includes a rotating shaft 17, a turntable 21 and multiple connecting rods 22. The turntable 21 is fixedly connected to the rotating shaft 17, and one end of each of the multiple connecting rods 22 is rotatably connected to one side of the turntable 21. One end of clamping rod 1 8 and clamping rod 2 9 are respectively rotatably connected to the connecting rods 22.

[0030] When in use, the turntable 21 can be rotated to make multiple connecting rods 22 rotate, thereby pulling the clamping rod 1 8 and clamping rod 2 9 in front to move inward to clamp the workpiece 2. When clamping the workpiece 2 with the same length on all four sides of the cross section, this can be directly and effectively fixed.

[0031] When clamping a workpiece 2 with inconsistent lengths on four sides of its cross section, an assembly rod 11 can be installed in the "L"-shaped slot on one side of the clamping rod 8 or the clamping rod 9. Different types of workpieces 2 can be clamped by installing different numbers of assembly rods 11. Then, an anti-slip plate 12 is installed in front of the frontmost assembly rod 11. A rubber strip is installed at the front end of the anti-slip plate 12, which can be fixed more firmly.

[0032] By assembling multiple different assembly rods 11, it is possible to quickly clamp common aluminum profiles of different specifications, and the clamping is more secure, reducing shaking and processing errors.

[0033] In this embodiment, one end of the clamping rod 8, the clamping rod 9 and the assembly rod 11 are respectively fixedly connected to an anti-detachment plate 10, and an anti-detachment groove 13 is opened on one side of the anti-slip plate 12 and the assembly rod 11, and the anti-detachment plate 10 can be inserted into the anti-detachment groove 13.

[0034] Clamping rod 18, clamping rod 29, assembly rod 11 and anti-slip plate 12 are each provided with mounting screw holes 14. The mounting screw holes 14 at one end of clamping rod 18 and clamping rod 29 are internally threaded with assembly screw 2 16, and the mounting screw holes 14 at one end of assembly rod 11 and anti-slip plate 12 are internally threaded with assembly screw 15.

[0035] During installation, the "T"-shaped anti-detachment plate 10 can be inserted into the corresponding anti-detachment groove 13 at the front to fix it and prevent it from falling off. At the same time, the assembly rod 11 and the anti-slip plate 12 can be fixed with the assembly screw 15 to improve the stability during processing. The assembly screw 16 can be turned into the mounting screw hole 14 at one end of the clamping rod 8 and clamping rod 9. The assembly rod 11 is reinforced by pressing the assembly screw 15 inside the assembly rod 11 by the end of the screw protruding from the through hole.

[0036] In this embodiment, the two ends of the rotating shaft 17 are rotatably connected to the clamping box 6, and a plurality of translation slots 7 are opened on one side of the clamping box 6. The clamping rod 1 8 and the clamping rod 2 9 are respectively slidably connected to the inner side of the corresponding translation slot 7.

[0037] The clamping box 6 can restrict the movement trajectory of clamping rod 1 8 and clamping rod 2 9 through the translation groove 7;

[0038] A worm gear 18 is fixedly connected to one side of the rotating shaft 17, and a worm 19 is rotatably connected to the inside of the clamping box 6. The other end of the worm 19 is fixedly connected to the drive shaft 20, and the worm 19 and the worm gear 18 mesh with each other.

[0039] The drive shaft 20 is rotated by the hexagonal nut, which in turn drives the worm gear 19 to rotate by the worm wheel 18, causing the clamping rod 18 and clamping rod 29 to move inward to clamp. The self-locking characteristic of the worm gear transmission is used to prevent the clamping rod 18 and clamping rod 29 from loosening due to vibration during processing.

[0040] In this embodiment: the drive shaft 20 is rotated by the hexagonal nut, and then the worm gear 18 drives the worm 19 to rotate, so that the clamping rod 18 and the clamping rod 29 move inward to clamp, and the self-locking characteristic of the worm gear transmission is used to prevent the clamping rod 18 and the clamping rod 29 from loosening due to vibration during processing.

[0041] This allows the turntable 21 to rotate, causing multiple connecting rods 22 to rotate, which in turn pulls the first clamping rod 8 and the second clamping rod 9 in front to move inward and clamp the workpiece 2. When clamping the workpiece 2 with the same length on all four sides of the cross section, this method can directly and effectively fix it.

[0042] When clamping a workpiece 2 with inconsistent lengths on four sides of its cross section, an assembly rod 11 can be installed in the "L"-shaped slot on one side of the clamping rod 8 or the clamping rod 9. Different types of workpieces 2 can be clamped by installing different numbers of assembly rods 11. Then, an anti-slip plate 12 is installed in front of the frontmost assembly rod 11. A rubber strip is installed at the front end of the anti-slip plate 12, which can be fixed more firmly.

[0043] By assembling multiple different assembly rods 11, it is possible to quickly clamp common aluminum profiles of different specifications, and the clamping is more secure, reducing shaking and processing errors.

[0044] During installation, the "T"-shaped anti-detachment plate 10 can be inserted into the corresponding anti-detachment groove 13 in front to fix it and prevent it from falling off. At the same time, the assembly rod 11 and the anti-slip plate 12 can be fixed with the assembly screw 15 to improve the stability during processing. The assembly screw 16 can be turned into the mounting screw hole 14 at one end of the clamping rod 8 and clamping rod 9. The assembly rod 11 is reinforced by pressing the assembly screw 15 inside the assembly rod 11 by the end of the end that protrudes from the through hole.

[0045] The clamping box 6 can restrict the movement trajectory of clamping rod 1 8 and clamping rod 2 9 through the translation groove 7.

[0046] Example 2:

[0047] This embodiment of the aluminum profile milling fixture is improved upon embodiment 1 by the following improvements: Figure 1-5 As shown, one end of the clamping box 6 is rotatably connected to a rotary joint 5, the other end of the rotary joint 5 is rotatably connected to a sliding bracket 3, and a support plate 4 is fixedly connected to one side of the sliding bracket 3.

[0048] The rotary joint 5 allows the clamping box 6 to rotate carrying the workpiece 2 for milling holes on different surfaces. The support plate 4 allows the clamping box 6 to be supported after rotating with the rotary joint 5 to a horizontal state, which facilitates the installation of the workpiece 2.

[0049] In this embodiment, a mounting plate 1 is slidably connected below the two sliding brackets 3, and a positioning bolt 23 is threadedly connected to one side of the sliding bracket 3;

[0050] The two clamping boxes 6 on both sides can hold the two ends of the workpiece 2, making the milling more stable, and the positioning bolts 23 can fix the position of the sliding bracket 3.

[0051] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
