Description

Technical Field

[0001] This utility model relates to the field of profile cross-cutting technology, specifically a positioning auxiliary device for profile cross-cutting. Background Technology

[0002] From the perspective of profile fixing, the core function of this positioning auxiliary device is to achieve fast, accurate, and reliable clamping and positioning, laying the foundation for high-quality cutting. It effectively eliminates dimensional deviations and cut damage caused by profile movement, vibration, or warping during the cutting process. This forced fixing not only overcomes the uncertainty of manual stabilization, ensuring dimensional consistency of each profile section in batch cutting, but also significantly improves the perpendicularity and smoothness of the cut surface.

[0003] The profile auxiliary positioning device disclosed in the existing patent publication number CN217668039U includes a sliding plate and a sliding column. The hydraulic rod is connected to a power source. Then, the operator places the profile on the placement plate. The power provided by the hydraulic rod can drive the sliding plate to slide in the track provided by the slide groove. The sliding plate drives the sliding column to move in the track provided by the placement plate, which in turn drives the fastening spring to move. This causes the fastening plate to move in conjunction with the slider in the track provided by the slide groove. When the fastening plate moves, it can drive the positioning bolt to move in the track provided by the positioning port, so that the profile can be fastened by the movement of the fastening plate.

[0004] The current fixing device uses two sets of fastening plates to clamp and limit the profile from both sides. However, at the moment of cross-cutting, the huge sawing force can easily cause the profile to undergo slight displacement or torsion within the fixture, causing the original positioning reference to fail, ultimately resulting in tilted cut surfaces or out-of-tolerance dimensions, producing defective products. To address the above problems, a positioning auxiliary device for cross-cutting profiles is proposed. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] 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.

[0026] Please see Figures 1-5 In this embodiment, the positioning auxiliary device for profile cross-cutting includes a worktable 11 and two sets of movable frames 12 that slide on the worktable 11. A lower pressure plate 13 is slidably connected inside the movable frame 12. An upper fixing plate 14 is provided at the bottom of the lower pressure plate 13. A guide component for limiting the movement of the lower pressure plate 13 is provided on the movable frame 12.

[0027] The guiding assembly includes guide rods 22 and springs 21. Several sets of guide rods 22 are fixedly connected to the top of the lower pressure plate 13. Springs 21 are sleeved on the guide rods 22. One end of spring 21 is connected to the top of the lower pressure plate 13, and the end of spring 21 away from the lower pressure plate 13 is connected to the top of the interior of the movable frame 12. Several sets of sliding holes are provided on the movable frame 12 for sliding with the guide rods 22. Guide blocks 24 are fixedly connected to both sides of the lower pressure plate 13. The inner walls of the movable frame 12 are respectively provided with sliding holes for sliding with the guide blocks 24. The guide groove 23 is movable, and the guide block 24 has a T-shaped cross section. The upper fixing plate 14 gradually moves downward towards the upper surface of the profile until it is in close contact with the profile. The lower pressure plate 13 drives the guide block 24 to slide upward in the guide groove 23 and squeeze the second spring 21. At the same time, the guide rod 22 slides upward on the moving frame 12. The elastic force generated when the second spring 21 on the guide rod 22 is compressed can allow the upper fixing plate 14 to apply continuous and uniform pressure to the profile, ensuring that the profile is stably fixed, effectively offsetting the torque generated during the cutting process, preventing deformation and displacement of the profile, and reducing the defect rate from the root.

[0028] The bottom of the workbench 11 is provided with a drive assembly for driving the two sets of moving frames 12 to slide synchronously, and the lower pressure plate 13 is provided with an installation assembly for fixing the upper fixed plate 14.

[0029] The drive assembly includes a movable plate 26 and an electro-hydraulic rod 28. The two sides of the movable plate 26 are respectively connected to the two sides of the inner wall of the movable frame 12 through connectors. Several sets of electro-hydraulic rods 28 are installed on the horizontal plate of the inner wall of the workbench 11. The power output ends of the several sets of electro-hydraulic rods 28 are connected to the bottom of the movable plate 26. When the electro-hydraulic rods 28 are activated, their power output ends drive the movable plate 26 to move downward. The movable plate 26 drives the two sets of movable frames 12 downward, and at the same time drives the upper fixed plate 14 to gradually approach the upper surface of the profile until it is tightly fitted with the profile, thus pressing and fixing the profile.

[0030] The mounting assembly includes a slot 15 and a positioning slot 16. The slot 15 is located on one side of the lower pressure plate 13, and two sets of positioning slots 16 are located on the top of the upper fixing plate 14. The upper fixing plate 14 is engaged within the slot 15. An arc-shaped positioning block 17 is engaged within each positioning slot 16. A movable groove 18 is provided on the top of the inner wall of the slot 15, and the arc-shaped positioning block 17 is slidably connected within the movable groove 18. A traction rod 19 is fixedly connected to one side of the arc-shaped positioning block 17, and a spring 20 is sleeved on the traction rod 19. One end of the spring 20 is connected to one side of the arc-shaped positioning block 17, and the spring 20 is located away from the arc-shaped positioning block 17. The upper fixing plate 14 is attached to the top of the inner wall of the moving groove 18 and is inserted into the slot 15. When the upper fixing plate 14 moves in the slot 15, it presses one side of the arc-shaped positioning block 17. The arc-shaped positioning block 17 slides upward in the moving groove 18 under pressure and presses the spring 20. After the positioning groove 16 moves to the position corresponding to the arc-shaped positioning block 17, the spring force of the spring 20 pops the arc-shaped positioning block 17 out, so that the arc-shaped positioning block 17 is engaged in the positioning groove 16, limiting the upper fixing plate 14 and preventing the upper fixing plate 14 from falling out in the slot 15. The whole structure does not need to be disassembled, which improves the device's adaptability to multiple specifications of profiles and enhances its practicality.

[0031] The connector includes a mounting plate 25 and several sets of positioning holes 27. The mounting plate 25 is fixedly connected to both sides of the inner wall of the movable frame 12. Several sets of positioning holes 27 are respectively opened on both sides of the movable plate 26. The mounting plate 25 is threaded with fixing bolts, which are threaded into the corresponding positioning holes 27. The movable frame 12 can be installed according to the cutting requirements, and the distance between the two sets of movable frames 12 can be flexibly adjusted to adapt to profiles of different lengths.

[0032] The bottom of the upper fixing plate 14 is provided with a lower fixing plate 29, which is bolted to the top of the workbench 11. By setting the lower fixing plate 29, the profile can be provided with bottom support, and together with the upper fixing plate 14, it can be fixed in both directions.

[0033] Two sets of corresponding pads are installed on the top of the workbench 11. By setting the pads, the profile can be prevented from directly contacting the workbench 11 and causing scratches. At the same time, raising the profile makes it easier to align the cutting position. The edge of the pad is aligned with the cutting line, and its height is slightly lower than the lower fixed plate 29 to prevent the tool from contacting the workbench 11 during cutting.

[0034] The working principle of this utility model is as follows: When in use, the profile is first passed through two sets of movable frames 12 and placed on two sets of lower fixed plates 29 and pads. The position of the profile is manually adjusted so that the part to be cut is aligned with the cutting area between the two sets of pads, preparing for subsequent fixing and cutting. The electric hydraulic rod 28 is started, and its power output end drives the movable plate 26 to move downward. The movable plate 26 drives the two sets of movable frames 12 downward, and at the same time drives the upper fixed plate 14 to gradually approach the upper surface of the profile until it is in close contact with the profile. The lower pressure plate 13 drives the guide block 24 to slide upward in the guide groove 23 and squeeze the spring 21. At the same time, the guide rod 22 slides upward on the movable frame 12. The elastic force generated when the spring 21 on the guide rod 22 is compressed allows the upper fixed plate 14 to apply continuous and uniform pressure to the profile, ensuring that the profile is stably fixed, effectively offsetting the torque generated during the cutting process, preventing deformation and displacement of the profile, and reducing the defect rate from the root.

[0035] Simultaneously, the upper fixing plate 14 can be replaced according to the cross-cutting requirements of different profile shapes. Pull the traction rod 19 upward, and the traction rod 19 will drive the arc-shaped positioning block 17 to slide in the moving groove 18 and squeeze the spring 20, disengaging it from the positioning groove 16. Pull the upper fixing plate 14 outward and disengage it from the slot 15. Then, use tools to remove the bolts on both sides of the lower fixing plate 29, install the replaced lower fixing plate 29 on the top of the workbench 11 with bolts, and then insert the replaced upper fixing plate 14 into the slot 15. When moving inward, the arc-shaped positioning block 17 is pressed on one side of its arc shape. Under the pressure, the arc-shaped positioning block 17 slides upward in the moving groove 18 and presses the spring 20. After the positioning groove 16 moves to the position corresponding to the arc-shaped positioning block 17, the spring force of the spring 20 pops the arc-shaped positioning block 17 out, so that the arc-shaped positioning block 17 is locked in the positioning groove 16, limiting the upper fixing plate 14 and preventing the upper fixing plate 14 from falling out in the slot 15. The whole structure does not need to be disassembled, which improves the device's adaptability to multiple specifications of profiles and enhances its practicality.

[0036] After cutting, the electric hydraulic rod 28 drives the moving plate 26 and the moving frame 12 to return to the starting position. The compressed spring 21 releases its elasticity, pushing the lower pressure plate 13 and the upper fixed plate 14 to return to the initial position simultaneously. The profile is then released, and the cut profile can be taken out, completing one processing cycle.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
