Technical Field

[0001] This utility model relates to the field of mechanical processing and manufacturing technology, and in particular to a guide rail straightening device. Background Technology

[0002] The weight device mainly consists of a base plate, guide rail, lateral displacement base, weight assembly, and lifting rod assembly. The guide rail is fixed to the base plate, the lateral displacement base is mounted on the guide rail, and the weight assembly and lifting rod assembly are installed on the base. Sliding occurs through the sliding between the lateral displacement base and the guide rail. To ensure stable and reliable sliding, high requirements are placed on the surface roughness of the guide rail, dimensional tolerance control, and the parallelism of the guide rail side and the perpendicularity of the side to the sliding surface; the accuracy of the guide rail must be guaranteed. However, currently, deformation occurs after the guide rail is manufactured, increasing the scrap rate. Therefore, a device capable of straightening the guide rail is needed.

Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention.

[0019] like Figure 1-2As shown, a guide rail straightening device includes a support frame 1 and a straightening worktable 2 fixedly installed on the support frame 1, and also includes a fixed seat 5, a lead screw 6, an adjusting block 7 and two limiting blocks 4;

[0020] The straightening worktable 2 has two parallel T-slots. One T-slot is positioned opposite the two limiting blocks 4, and the other T-slot is positioned opposite the fixing seat 5. The fixing seat 5 and the limiting blocks 4 are fixedly mounted on the T-blocks 3, and the T-blocks 3 slide in conjunction with the T-slots. The fixing seat 5 has threaded holes, and the lead screw 6 engages with the threaded holes. The end of the lead screw 6 near the limiting blocks 4 is fixedly connected to the adjusting block 7. The T-blocks facilitate adjustment and are fixedly connected by fastening bolts. During fixing, the limiting blocks and adjusting blocks are pressed against the straightening worktable using the fastening bolts to achieve positional fixation.

[0021] In practice, the ends of the limiting block 4 and the adjusting block 7 that are close to each other are arranged in an arc.

[0022] In practice, the limiting block 4 and the fixing seat 5 are both provided with through holes, and the T-block 3 is provided with threaded holes. The limiting block 4, the fixing seat 5 and the T-block 3 are fixedly connected by fastening bolts 9.

[0023] In practice, the fixing base 5 has four rectangular through holes, and the T-block 3 has two threaded holes. The four through holes allow for adjustment of the distance between the limiting block and the adjusting block. When installing the limiting block and the fixing base, the corresponding through hole position can be selected according to the distance.

[0024] During implementation, a spring washer 11 and a flat washer 10 are provided between the fastening bolt 9, the limiting block 4, and the fixing seat 5.

[0025] The platform surface of the straightening workbench is cast, and a support frame is welded from profiles to support the entire platform surface. The support frame is fixed firmly and stably. The platform surface is then installed onto the support frame. The platform surface is designed with T-slots to facilitate the fixing of the mounting base to the workbench using T-blocks and fastening bolts. Through adjustment and fitting, and with the use of a laser tracker for testing or metrological inspection, the flatness of the platform surface is ensured.

[0026] The limiting blocks, lead screws, fixed seats, adjusting blocks, T-blocks, and other structural parts are made of 45# steel. During processing, they undergo rough machining, heat treatment, and then finish machining to ensure overall strength and stability during use. The contact points between the limiting blocks, adjusting blocks, and guide rails are designed with rounded transitions, making the guide rails more susceptible to deformation under stress during straightening, thus facilitating straightening.

[0027] After the support frame 1 and the straightening workbench 2 are assembled and inspected, the T-blocks are installed into the T-slots on the platform surface. Then, the limit blocks and fixing seats are installed on the platform surface, adjusting the mounting holes to align with the threaded holes of the T-blocks, and ensuring that the R-arc points of the two limit blocks are on a straight line. The installation is then secured with bolts and washers. Next, the lead screw is installed onto the fixing seat, and an adjustable wrench is used to fully retract the lead screw. The adjusting block and lead screw are then assembled. The direction of the highest point of the bent arc of the guide rail is aligned with the adjusting block.

[0028] After installing the aforementioned components and placing the guide rail in place, check the straight-line deformation and bending of the guide rail. Then, adjust the positions of the left and right limit blocks and adjusting blocks, ensuring that the adjusting block is positioned between the two limit blocks and at the highest point of the guide rail's bending arc. The distance between the two limit blocks and the adjusting block can be adjusted according to the actual deformation of the guide rail. Slowly move the lead screw using an adjustable wrench to push the adjusting block and push the guide rail, causing it to deform under force. Measure the deformation using a dial indicator. When the guide rail meets the straightness requirements, stop moving the lead screw and allow it to stand still for 5-10 minutes. Then, rotate the lead screw in the opposite direction, release the adjusting block, and check the guide rail deformation again. If springback occurs and the straightness requirements are not met, repeat the above process, pushing and pressing, until the guide rail meets the requirements. During the operation, deformation should be controlled to avoid over-pushing and forming S-shaped deformation, thus achieving the purpose of straightening the guide rail.

[0029] The guide rail straightening device of this embodiment has a simple structure, is easy to control and operate, and is simple to operate and easy to inspect, without complicated operation procedures. At the same time, the limiting block and fixing seat are designed with two sets of mounting holes, which facilitates adjustment according to guide rails of different sizes. It has high installation, fixing, and straightening efficiency, effectively solving the problem of guide rail deformation after processing, and has the same implementation effect on similar slender guide rail parts. Compared with not using this straightening method, for the processing of slender guide rail parts, it solves the problem of deformation caused by difficulty in controlling the processing, which leads to unusable parts, and reduces the risk of scrapping. Through practical application verification, this guide rail straightening device implementation plan is feasible. The straightening device can be reused multiple times and is suitable for batch and rapid straightening of guide rails, with high application value, achieving the goals of cost reduction, efficiency improvement, and ensuring guide rail quality.

[0030] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
