Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, and in particular to a large-section profile assembly fixing device. Background Technology

[0002] Bending and twisting are unavoidable during the manufacturing process of profiles. The larger the cross-section, the thicker the profile, and the longer the length, the greater the deformation and the more difficult it is to correct. When profiles are directly used as the outer shape of a product or structural components with strength requirements, the manufacturing errors of the profiles themselves will affect the shape or structural strength of the product. This requires effective control and correction when using these profiles to manufacture products, in order to reduce subsequent adjustments, secondary processing, or processing workload, thereby effectively improving production efficiency and avoiding the impact of excessive processing on product strength.

[0003] In actual production, CNC equipment is being used more and more widely. This places higher and higher demands on tooling and fixtures for controlling the state of profiles. In particular, CNC equipment has stricter requirements for the space of the running trajectory. This requires that tooling or fixtures must be accurately and reliably positioned, have a compact structure, and be easy to use.

[0004] Controlling the condition of large-section profiles is extremely difficult, especially controlling their torsional deformation. If not controlled properly, post-processing or adjustment of the product is necessary to meet the technical requirements. This adjustment or adjustment will result in a significant waste of manpower, equipment, and energy for the company; it may also increase the amount of processing required, thereby reducing the strength of the profiles and the product.

[0028] To facilitate understanding of the embodiments of this utility model, the structure of this utility model will be described in detail below through several specific embodiments.

[0029] Figure 1 This is a front structural diagram of a large cross-section profile combination fixing device according to the present invention; Figure 2 This is a side view of a large cross-section profile combination fixing device according to the present invention.

[0030] according to Figure 1 and Figure 2 As shown, this utility model provides a large-section profile assembly fixing device. To understand the structure and function of the large-section profile assembly fixing device, a general description of the device is provided first to ensure a thorough understanding of this utility model.

[0031] This utility model provides a large-section profile assembly fixing device, including:

[0032] The contour positioning seat 1 includes a base 11 and a side support seat 12 connected to the upper surface of the base 11, for placing the profile 5;

[0033] The upper clamping device 2 is connected to the top of the side support 12 and is used to limit the profile 5 in conjunction with the base 11;

[0034] The top tensioning device 3 is located on the upper side of the side support 12;

[0035] Bottom tensioning device 4 is installed on base 11;

[0036] The top tensioning device 3 and the bottom tensioning device 4 respectively drive the profile 5 to abut against the side support seat 12 to limit the profile 5.

[0037] When using the large-section profile assembly fixing device, install the profile 5 onto the contour positioning seat 1 in the correct direction. Fix the profile 5 using the bottom tensioning device 4, the top tensioning device 3, and the upper pressing device 2, and pre-tighten it. Then observe the gap between the profile 5 and the contour positioning seat 1. Adjust the bottom tensioning device 4, the top tensioning device 3, and the upper pressing device 2 gradually and multiple times according to the size of the gap. Adjust the profile 5 gradually and multiple times using the corresponding tensioning and pressing devices to ensure that the gap between the profile 5 and the contour positioning seat 1 is eliminated. Then, start to tighten the bottom tensioning rod 41, the top tensioning device 3, and the upper pressing device 2 from the middle of the profile 5 to both sides, and then proceed with the subsequent work.

[0038] The base 11 and the side support 12 are respectively provided with a bottom positioning protective plate 111 and a side positioning protective plate 121 on the side surfaces that are close to each other.

[0039] In this embodiment, the positioning protective plate 111 and the side positioning protective plate 121 are fixed to the base 11 and the side support 12 by screws, respectively, to protect the surface of the profile 5 and effectively prevent scratches or bumps during operation.

[0040] In an optional embodiment, the positioning protective plate 111 and the side positioning protective plate 121 are fixed to the base 11 and the side support 12 by adhesive bonding, which can also serve to protect the surface of the profile 5. Furthermore, by adhesive bonding, the surfaces of the positioning protective plate 111 and the side positioning protective plate 121 are smoother, and the effect of preventing scratches is better.

[0041] The upper clamping device 2 includes: an upper clamping rod 21 and a clamping connection part 22.

[0042] One end of the clamping connection 22 is connected to the top of the side support 12, and the other end is rotatably connected to the upper clamping rod 21, the height of which can be adjusted vertically. In this embodiment, the upper clamping rod 21 of the clamping connection 22 is connected to the clamping connection 22 through a screw structure. When it is necessary to clamp the profile 5 in the vertical direction, the upper clamping rod 21 is rotated. At this time, due to the action of the screw structure, the upper clamping rod 21 will move downward while rotating, thereby clamping the profile 5 and making the profile 5 fit against the base 11 of the contour positioning seat 1.

[0043] In one alternative embodiment, the upper clamping rod 21 is a cylinder. By stretching the cylinder, the upper clamping rod 21 can move in the vertical direction, thereby clamping and releasing the profile 5.

[0044] One end of the clamping connection 22 is rotatably connected to the top of the side support 12. By rotating the clamping connection 22, the distance between the upper clamping rod 21 and the plane of the side positioning protective plate 121 can be adjusted. In a preferred embodiment, one end of the clamping connection 22 is rotatably connected to the top of the side support 12. When fixing profiles 5 with different cross-sectional thicknesses, the distance between the upper clamping rod 21 and the plane of the side positioning protective plate 121 can be adjusted by rotating the clamping connection 22, so that the upper clamping rod 21 can clamp the profile 5 at the most suitable position, thereby adapting to the operational needs of profiles 5 with different cross-sectional thicknesses.

[0045] In a preferred embodiment, the bottom of the upper clamping rod 21 is connected to a support pad 211. When the profile 5 is clamped, the upper clamping rod 21 holds the profile 5 against the support pad 211 to avoid scratches and bumps to the profile 5 caused by directly pressing against it.

[0046] The top tensioning device 3 includes: a top tensioning rod 31, a tensioning connection part 32, and a profile fixing part 33.

[0047] The tensioning connection 32 is connected to the upper side surface of the side support 12. The top tensioning rod 31 is movably connected to the tensioning connection 32. The profile fixing part 33 is rotatably connected to one end of the top tensioning rod 31. The top tensioning rod 31 can move relative to the tensioning connection 32 along its length, thereby driving the profile fixing part 33 to move relative to the tensioning connection 32, adjusting the distance between the profile fixing part 33 and the tensioning connection 32. In this embodiment, the tensioning connection 32 is fixedly connected to the upper side surface of the side support 12. The top tensioning rod 31 and the tensioning connection 32 are connected by a screw structure. When it is necessary to tension the profile 5, the top tensioning rod 31 is rotated. At this time, due to the action of the screw structure, the profile fixing part 33 can be driven to move relative to the tensioning connection 32, thereby adjusting the distance between the profile fixing part 33 and the tensioning connection 32.

[0048] A groove 331 is provided at the bottom of the profile fixing part 33. The width of the groove 331 is slightly larger than the cross-sectional thickness of the profile 5, so that the profile 5 can be inserted into the groove and provide a force point for the profile 5 to be tightened.

[0049] In one alternative embodiment, the top tensioning rod 31 is a cylinder. By stretching the cylinder, the profile fixing part 33 is stretched, thereby achieving the tensioning and loosening of the profile 5.

[0050] In a preferred embodiment, tensioning connection portions 32 are provided on both opposite sides of the side support seat 12. When the profile 5 is tensioned, the profile 5 is tensioned from both sides of the side support seat 12, thereby tensioning the profile 5 more fully and achieving better working results.

[0051] The bottom tensioning device 4 includes a bottom tensioning rod 41 and a fixed tensioning component 42. The fixed tensioning component 42 includes a limiting frame 421 disposed on the base 11 for placing the profile 5 in the area. The bottom tensioning rod 41 is connected to the limiting frame 421. The bottom tensioning rod 41 can move back and forth along its length to drive the limiting frame 421 to move, so that the limiting frame 421 drives the profile 5 to abut against the side positioning protective plate 121.

[0052] In this embodiment, when the profile is placed in the area of ​​the base and side support profile of the contour positioning seat 1, the bottom of the profile is located between the side support 12 and the limiting frame 421.

[0053] Furthermore, the bottom tension rod 41 can be configured to pass through the side support seat 12 and connect to the limiting frame 421. Moreover, the bottom tension rod and the side support seat 12 form a screw structure. Then, by reciprocating the rotation of the bottom tension rod, the limiting frame 421 can be driven to move towards the side positioning protective plate 121 to abut against the side positioning protective plate 121. Of course, the following configuration can also be made: the bottom tension rod can be connected to a power mechanism such as a cylinder and / or a hydraulic cylinder and / or a motor. Through the power mechanism, the bottom tension rod can drive the limiting frame 421 to move to abut against the side positioning protective plate 121. Therefore, the bottom tension rod can drive the frame to move, so that the limiting frame 421 drives the profile 5 to abut against the side positioning protective plate 121, thereby achieving fixed limiting of the bottom of the profile.

[0054] The following settings can also be made for the aforementioned fixing and tensioning component 42:

[0055] Four frame edges are connected end to end to form a fixed tensioning component 42, which is used to fit the profile 5. The aforementioned limiting frame 421 is the frame that faces the side positioning protective plate 121 among the four frame edges. Moreover, the limiting frame 421 is movably connected to the frame edges on both sides. When it is necessary to tighten the profile 5, the limiting frame 421 is driven to move toward the side positioning protective plate 121 by adjusting the bottom tensioning rod 41 so as to abut against the side positioning protective plate 121, thereby achieving the tightening and fixed limiting of the profile 5.

[0056] In a preferred embodiment, a side guard plate 43 is provided on the side of the limiting frame 421 facing the side positioning guard plate 121, which can prevent the profile 5 from being scratched or bumped by directly pressing against it.

[0057] In one optional embodiment, a large cross-section profile assembly fixing device further includes a stabilizing component connected below the base 11 of the contour positioning seat 1, which is used to increase the friction between the contour positioning seat 1 and the ground, while ensuring the stability of the large cross-section profile assembly fixing device during operation.

[0058] After profile 5 is fixed by the large-section profile assembly fixing device, the shape and state of the profile are effectively guaranteed by the contour positioning seat 1. The positioning surface of the positioning seat can effectively guarantee the final position and state of the profile. Multiple upper clamping devices 2, top tensioning devices 3, and bottom tensioning devices 4 can effectively eliminate the bending and twisting deformation of the profile itself, achieving the technical indicators such as the required contour and dimensions of the product. In the later stage, the position of the contour positioning seat 1 can be adjusted or anti-deformation processes can be added based on the actual deformation of the product part to achieve a more ideal technical state of the product part.

[0059] In summary, the advantages and beneficial effects of this utility model's combined fixing device for large cross-section profiles are:

[0060] 1. The positioning is simple, accurate and intuitive. As long as the profile 5 is in contact with all the positioning surfaces of the contour seat, the positioning is accurate and reliable, ensuring the strength of the profile and the product.

[0061] 2. Wide range of applications: It can be applied to the processing of other profiles simply by changing the shape of the positioning surface and the structure of the tensioning head according to the profile 5 outline;

[0062] 3. Independent control of the tension and compression of the profile can locally eliminate the deformation of the profile itself and ensure the fit between the profile and the positioning surface;

[0063] 4. The compact structure provides ample operating space for CNC equipment, facilitating maintenance or processing and effectively reducing waste of manpower, equipment, and energy.

[0064] 5. The structure is simple, using standard structural components, with strong versatility, easy maintenance and replacement, and convenient use, reducing later operating costs and effectively improving production efficiency. Although the present invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
