[0025] This utility model addresses the problem that clamps often fail to properly fit against the outer wall of steel grid poles during clamping, resulting in inaccurate clamping and positioning, leading to positional deviations and improper angles during welding, thus reducing welding precision and stability. It provides a solution such as… Figures 1-3 The device shown is a spot welding assembly positioning fixture for steel space frame members. It includes multiple first mounting rods 1 and multiple second mounting rods 2. Connecting frames 3 are fixedly connected to the top and bottom surfaces of both the first mounting rods 1 and 2. The first mounting rods 1 and 2 are vertically arranged, and the first mounting rods 1 and 2 located at the top or bottom are slidably connected inside the corresponding connecting frames 3. During welding, the bottom steel space frame member is placed on a flat surface, and the spacing between the first mounting rods 1 and 2 is adjusted so that they can fit over the bottom steel space frame member. The device is then moved... The first mounting rod 1 or the second mounting rod 2 slides on the connecting frame 3. After adjustment, it is fitted onto the bottom steel grid frame rod. Then, the top steel grid frame rod is vertically installed on top, so that the ends of the steel grid frame rod are vertically fixed on the same vertical line. The first mounting rod 1 and the second mounting rod 2 at the top are slid upwards so that they are located on the top steel grid frame rod. The steel grid frame rod is positioned and clamped by the cooperation of subsequent components. Through the adjustable setting of the first mounting rod 1 and the second mounting rod 2, steel grid frame rods of different sizes can be clamped and positioned, which has good applicability.

[0026] Furthermore, both the inner walls of the first mounting rod 1 and the second mounting rod 2 are slidably equipped with snap-fit ​​plates 43. The snap-fit ​​plates 43 are arc-shaped and elastic. Scrapers 52 are slidably arranged between the two first mounting rods 1 and the two second mounting rods 2 located on the same vertical plane. After the first mounting rods 1 and the second mounting rods 2 are installed, the snap-fit ​​plates 43 are adjusted and moved. The snap-fit ​​plates 43 are tightly fitted with the side wall of the steel grid pole. The first mounting rods 1 and the second mounting rods 2 are fixed by the snap-fit ​​plates 43, and the scrapers 52 are fitted with the outer wall of the steel grid pole. The steel grid pole is cleaned by the scrapers 52. The scrapers 52 are slidable and scrape the outer wall of the steel grid pole. With the scrapers 52, workers can effectively remove impurities from the surface of the steel grid pole, ensuring the purity of the welded joint and thus improving the welding quality.

[0027] In this utility model, two columnar rods 5 are provided on the fixing block 4. A sliding plate 51 is slidably connected to the outer periphery of the columnar rods 5. The end of the sliding plate 51 is fixedly connected to the mounting bracket of the scraper 52. The columnar rods 5 can connect the first mounting rod 1 and the second mounting rod 2 at the top and bottom, which facilitates the fixing of the steel grid frame pole. At the same time, the columnar rods 5 facilitate the sliding plate 51 to slide up and down. When using the scraper 52, the steel grid frame pole can be cleaned by holding the sliding plate 51 and pulling the sliding plate 51 up and down.

[0028] It should be noted that the mounting bracket of scraper 52 is fixed to sliding plate 51 by bolts, which is a mature technology in the prior art and will not be described in detail here.

[0029] Furthermore, the design of scraper 52 makes cleaning more efficient and convenient, eliminating the need for additional tools or consumables, saving operation time and facilitating subsequent welding.

[0030] It should be noted that scraper 52 comes in different sizes and shapes, making it easy to change to different types according to the shape and size of the steel grid pole, thus enabling better cleaning.

[0031] In this utility model, a fixing block 4 is fixedly connected to the middle of the outer wall of both the first mounting rod 1 and the second mounting rod 2. A screw rod 42 is provided on the side wall of the fixing block 4. A screw hole is opened on the fixing block 4. The screw rod 42 is connected to the screw hole. The end of the screw rod 42 passes through the corresponding first mounting rod 1 or second mounting rod 2 and is rotatably connected to the side wall of the corresponding snap-fit ​​plate 43. In use, the screw rod 42 is rotated, and the screw rod 42 rotates to drive the snap-fit ​​plate 43 to move. After the snap-fit ​​plate 43 is attached to the outer wall of the steel grid frame pole, the steel grid frame pole is fixed.

[0032] It should be noted that two sliding rods 44 are slidably provided on the fixing block 4. The sliding rods 44 pass through the fixing block 4 and the corresponding first mounting rod 1 or second mounting rod 2 and are fixedly connected to the side wall of the snap-fit ​​plate 43. The sliding rods 44 help limit the movement, so that the snap-fit ​​plate 43 can move along a predetermined trajectory, which makes it easier for the snap-fit ​​plate 43 to better fix the steel grid pole.

[0033] Furthermore, due to the arc-shaped design of the clamping plate 43, it can closely fit the outer wall of the steel grid pole, thereby achieving precise clamping and positioning. This reduces positional deviations and improper angles during welding, ensuring the accuracy of position and angle during welding, improving welding precision and stability, increasing welding efficiency, and guaranteeing welding quality. Moreover, the arc-shaped design of the clamping plate can evenly distribute pressure during clamping, reducing friction and wear between the steel grid pole and the clamp, which helps extend the service life of both the steel grid pole and the clamp, and reduces maintenance costs.

[0034] The flexible design of the snap-fit ​​plate 43 can adapt to steel grid poles of different diameters and shapes, improving its practicality and versatility.

[0035] In this utility model, the top and bottom of the column rod 5 are threaded with two nuts 41, and the column rod 5 is fixedly connected to the corresponding fixing block 4 through the corresponding nuts 41. When installing the first mounting rod 1 and the second mounting rod 2 at the top, the fixing block 4 on them is inserted into the corresponding column rod 5, the height is adjusted, and after the adjustment is completed, the fixing block 4 is fixed to the column rod 5 with the nuts 41 to complete the installation.

[0036] It should be noted that multiple threaded holes 32 are provided through the first mounting rod 1 or the second mounting rod 2, and multiple through holes 31 are provided through the connecting bracket 3. Two threaded rods 33 are provided on the first mounting rod 1 and the second mounting rod 2. The threaded rods 33 pass through the corresponding through holes 31 and are threadedly connected to the corresponding threaded holes 32. After the size of the first mounting rod 1 and the second mounting rod 2 is adjusted, the threaded rods 33 are used to fix the first mounting rod 1 and the second mounting rod 2 for easy adjustment.
