Technical Field
[0001] This utility model relates to the field of aluminum alloy frame processing technology, and in particular to a high-precision processing equipment for aluminum alloy frames. Background Technology
[0002] In the field of aluminum alloy frame processing, traditional cutting equipment often faces three major pain points: First, the frame clamping and positioning accuracy is insufficient, manual correction is time-consuming and prone to cumulative errors, resulting in tilted cutting surfaces or dimensional deviations; second, the angle adjustment mechanism has poor rigidity, relying mostly on indexing plates or preset holes, making it difficult to achieve continuous stepless angle adjustment and limiting the flexibility of processing irregularly shaped frames; third, cutting debris accumulates on the worktable, not only interfering with the processing view but also easily scratching the frame surface or intruding into the moving parts, reducing the equipment's lifespan. Although existing equipment attempts to improve this by adding guiding mechanisms or chip collection grooves, the overall structure is redundant. Therefore, we propose a high-precision processing equipment for aluminum alloy frames. Utility Model Content

The first connecting block and the third sliding block are inverted L-shaped blocks. A second threaded hole is opened on the upper side of the third sliding block. A second locking threaded post is threadedly connected inside the second threaded hole. A material feeding groove is opened on the upper side of the cutting table. A cutting machine is arranged above the cutting table at the position corresponding to the material feeding groove. A guide box is fixedly installed on the bottom side of the cutting table. The guide box is a hollow box with right angled triangles.

[0007] Preferably, the upper side of the third sliding block is provided with a second guide hole, and the upper side of the slider is provided with a fourth threaded hole at the position of the second guide hole. The cross-section of the fourth threaded hole is a "T"-shaped cylindrical cavity.

[0011] This utility model provides a high-precision machining equipment for aluminum alloy frames. It has the following beneficial effects:
[0012] (1) This high-precision machining equipment for aluminum alloy frames achieves bidirectional rapid positioning of the aluminum alloy frame through the symmetrical sliding design of the first and second sliding blocks, combined with the collaborative correction mechanism of the inverted L-shaped first connecting block and the third sliding block. It pushes the third sliding block to move along the first groove on the second sliding block, forcing the side of the frame to be in close contact with the reference surface of the first connecting block, thus eliminating clamping gaps. The first locking threaded post penetrates the frame and is inserted into the first threaded hole, while the second locking threaded post penetrates the frame and is fixed in the second threaded hole, effectively resisting cutting vibration. The closed-loop drive system composed of the screw nut mounting seat and the rotating screw is precisely controlled by the rotary motor to control the displacement of the sliding block, avoiding positioning drift caused by manual pushing and pulling. This structure integrates frame correction, locking, and feeding into one unit, solving the problem of cut deviation from the root.
[0013] (2) The aluminum alloy frame high-precision processing equipment has flexible angle adaptation: the first connecting block can rotate around the first sliding block, and the third sliding block can rotate through the slider. The two are respectively driven by the third threaded column to the first locking block in the T-shaped cavity and the fourth threaded column to the second extrusion block to make surface contact and press, providing strong torsional rigidity. The right-angled triangular guide box uses the inclined surface to collect the debris and discharge it downward. The telescopic rod drives the moving plate to swing back and forth at high frequency through the guide block in the constraint groove, pushing the debris to the chip collection area in a direction to avoid accumulation and blockage of the feeding chute.

[0023] like Figures 1-4As shown, a high-precision machining equipment for aluminum alloy frames includes a cutting table 1, which is a U-shaped block. A first sliding block 2 and a second sliding block 6 are symmetrically arranged and slidably mounted on the upper side of the cutting table 1. A first connecting block 3 is rotatably mounted on the upper side of the first sliding block 2. First threaded holes 4 are equidistantly opened on the upper side of the first connecting block 3, and a first locking threaded post 5 is threaded into the interior of the first threaded hole 4. A movable third sliding block 7 is arranged above the second sliding block 6. The first connecting block 3 and the third sliding block 7 are inverted L-shaped blocks. The upper side of the third sliding block 7 is... A second threaded hole 8 is provided, and a second locking threaded post 9 is connected to the internal thread of the second threaded hole 8. A material feeding groove 10 is provided on the upper side of the cutting table 1. A cutting machine is set above the cutting table 1 at the position corresponding to the material feeding groove 10. A guide box 11 is fixedly installed on the bottom side of the cutting table 1. The guide box 11 is a hollow box with right angled triangles. In use, one side of the aluminum alloy frame to be cut is installed on the first sliding block 2, and the other side of the aluminum alloy frame is placed on the second sliding block 6. The third sliding block 7 is pushed, and the third sliding block 7 pushes the side of the aluminum alloy frame to cut. The movement allows the other side of the aluminum alloy frame to contact the side of the first connecting block 3 for alignment. The aluminum alloy frame is then fixed by the first locking threaded post 5 and the second locking threaded post 9. Moving the first sliding block 2 and the second sliding block 6 brings the aluminum alloy frame into contact with the cutting machine, initiating the cutting action. The debris falls through the feed chute 10 into the guide box 11 for guidance. The first connecting block 3 can swing on the first sliding block 2, and the third sliding block 7 can swing on the second sliding block 6 to change the angle of the aluminum alloy frame during cutting. The guide box 11 has a reciprocating movable plate 22 inside. The movable plate 22 is a rectangular plate that matches the inner side line of the guide box 11. A constraint groove 23 is provided on the side of the guide box 11. A guide block 25 is slidably installed inside the constraint groove 23. One side of the guide block 25 is fixedly connected to the bottom side of the movable plate 22. A fixed telescopic rod 24 is provided on the side of the guide box 11. The output end of the telescopic rod 24 is fixedly installed on the side of the guide block 25. The telescopic rod 24 drives the guide block 25 to reciprocate, and the guide block 25 drives the movable plate 22 to reciprocate.
[0024] The first connecting block 3 has a first guide hole 13 on its upper side. The first sliding block 2 has a third threaded hole 12 on its upper side corresponding to the first guide hole 13. A third threaded post 14 is threaded into the third threaded hole 12. A first locking block 15 is fixedly installed at the lower end of the third threaded post 14 inside the third threaded hole 12. The third threaded hole 12 has a T-shaped cylindrical cavity. The first connecting block 3 rotates on the first sliding block 2, and the rotation of the first connecting block 3 is locked by the third threaded post 14 and the first locking block 15. The second sliding block 6 has a first sliding groove 16 on its upper side. A slider 17 is slidably installed inside the first sliding groove 16. The sliding block 7 is rotatably mounted above the slider 17. The third sliding block 7 slides inside the first groove 16 via the slider 17. A second guide hole 19 is provided on the upper side of the third sliding block 7. A fourth threaded hole 18 is provided on the upper side of the slider 17 corresponding to the position of the second guide hole 19. The cross-section of the fourth threaded hole 18 is a "T"-shaped cylindrical cavity. A fourth threaded post 20 is threadedly connected inside the fourth threaded hole 18. A second pressing block 21 is fixedly installed at the lower end of the fourth threaded post 20 corresponding to the inside of the fourth threaded hole 18. The third sliding block 7 rotates on the slider 17. The rotation of the third sliding block 7 is locked by the fourth threaded post 20 and the second pressing block 21.
[0025] The cutting table 1 has second grooves 26 on its side corresponding to the positions of the first sliding block 2 and the second sliding block 6. The second sliding block 6 and the first sliding block 2 are slidably installed inside the two second grooves 26. The sides of the second sliding block 6 and the first sliding block 2 are fixedly installed with screw nut mounting seats 27. The side of the cutting table 1 is fixedly installed with a rotary motor 28 corresponding to the position of the screw nut mounting seats 27. The output end of the rotary motor 28 is fixedly installed with a rotary screw 29. The rotary screw 29 is threaded into the inside of the screw nut mounting seats 27. When the rotary motor 28 is started, the rotary motor 28 drives the rotary screw 29 to rotate. The rotary screw 29 drives the screw nut mounting seats 27 to move laterally. The two screw nut mounting seats 27 respectively drive the first sliding block 2 and the second sliding block 6 to move laterally. The first sliding block 2 and the second sliding block 6 drive the aluminum alloy frame to move laterally to perform cutting.
[0026] The working principle of this utility model:
[0027] In use, first place one side of the aluminum alloy frame on the first connecting block 3 at the top of the first sliding block 2, and the other side on the second sliding block 6. Manually push the third sliding block 7 so that it slides along the first sliding groove 16 and presses against the side of the frame, forcing the other end of the frame to fully fit against the vertical reference plane of the first connecting block 3, completing the initial correction. Tighten the first locking threaded post 5 and the second locking threaded post 9, which pass through the frame and press into the first threaded hole 4 and the second threaded hole 8 respectively, to achieve rigid fixation of the frame. If angle cutting is required, loosen the third threaded post 14 and the fourth threaded post 20, so that the first connecting block 3 rotates around the first sliding block 2 and the third sliding block 7 rotates around the slider 17, driving the frame to the target angle and then relocking it. At this time, the first locking block 15 at the lower end of the third threaded post 14 expands radially in the third threaded hole 12 of the T-shaped section to press against the hole wall, and the fourth threaded post 20 produces the same effect in the fourth threaded hole 18 through the second extrusion block 21, forming a self-reinforcing mechanical lock. The rotary motor 28 is started, driving the rotary lead screw 29 to rotate. This causes the lead screw nut mounting seat 27, which is threaded to it, to move laterally along the second slide groove 26. Simultaneously, the first sliding block 2 and the second sliding block 6 are precisely fed along with the frame, and the cutting is completed by the cutting machine. The generated debris falls into the bottom of the inclined surface of the guide box 11 through the feeding groove 10. The telescopic rod 24 periodically pushes the guide block 25 to slide in the constraint groove 23, causing the moving plate 22 to scrape back and forth in the triangular cavity, continuously pushing the debris towards the chip discharge port and keeping the processing area clean.
[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
