Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention.

As shown in fig. 1, a precise positioning and correcting device for a bridge bracket arm comprises a lower plate 1, two fixing plates 2 and two L-shaped connecting plates 3, wherein the two fixing plates 2 are respectively vertically and slidably mounted on longitudinal sections of the two connecting plates 3 (the longitudinal section is a section with a short L-shape, and the transverse section is a section with a long L-shape), a chute 4 is formed in the lower plate 1, transverse sections of the two connecting plates 3 are slidably mounted on the lower plate 1 through the chute 4, the connecting plates 3 can enable the two fixing plates 2 to be close to or away from each other by sliding on the lower plate 1, the fixing plates 2 can vertically and slidably move on the connecting plates 3 to enable the lower plate 1 to be close to or away from the lower plate 2, when the device is used, the fixing plates 2 are lifted up, the fixing plates 2 are made to slide on the longitudinal sections of the connecting plates 3, the fixing plates 2 are made to be away from the lower plate 1, one steel plate is placed between the lower plate 1 and the fixing plate 2, and when the two fixing plates are made to be close to a steel plate in another vertical state, welding is performed, and the steel plate is enabled to be better than the existing steel plate fixing, and the steel plate is welded, so that the verticality is reduced, and the steel plate displacement is ensured.

As shown in fig. 1 and 4, in some embodiments, a connecting rod 5 is fixedly mounted on the fixing plate 2, the connecting rod 5 is slidably connected to a longitudinal section of the connecting plate 3, a spring 6 is mounted between the connecting rod 5 and the connecting plate 3, the spring 6 forces the fixing plate 2 to move in a direction close to the lower plate 1, the spring 6 provides a force in a direction toward the lower plate 1 when the steel plate is fixed, so that the fixing plate 2 fixes the steel plate more stably, and the force provided by the spring 6 also resets the fixing plate 2 when the steel plate is removed after use, without additional manual operation.

As shown in fig. 2 and 3, in some embodiments, the adjusting device 7 acting on the two connecting plates 3 is installed on the lower plate 1, and the distance between the two connecting plates 3 is adjusted by the adjusting device 7, so that the fixing plate 2 slidably installed on the connecting plates 3 can be adapted to steel plates of different specifications.

As shown in fig. 2, in some embodiments, the adjusting device 7 includes a threaded rod 701 rotatably installed in the lower plate 1, the threaded rod 701 is configured with two opposite sections and is in threaded fit with the transverse ends of the two connecting plates 3 through threads, a worm wheel 702 is fixedly and concentrically installed on the threaded rod 701, a worm 703 engaged with the worm wheel 702 is rotatably installed on the lower plate 1, the worm wheel 702 is driven to rotate by rotating the worm 703, because the worm wheel 702 is fixedly connected with the threaded rod 701, the worm wheel 702 drives the threaded rod 701 to rotate along its axis when rotating, and because the two ends of the threaded rod 701 are in reverse threaded fit with the connecting plates 3, the two connecting plates 3 can be close to or far away from each other to adjust the distance between the connecting plates 3, when the connecting plates 3 are close to each other by rotating the worm, the connecting plates 3 drive the fixing plates 703 to approach each other to clamp the steel plates, and when welding is completed, the worm is rotated reversely to drive the connecting plates 3 to drive the fixing plates 2 to be far away from each other, thereby facilitating taking out the welded steel plates.

As shown in fig. 5, in some embodiments, a knob 8 is fixedly installed at one end of the worm 703 located outside the lower plate 1, and the worm 703 is rotated by rotating the knob 8, so that the operation is facilitated, and the use experience of a user is improved.

As shown in fig. 3, in some embodiments, the fixing plate 2 is L-shaped, and a side of the fixing plate 2 having a notch faces the lower plate 1, through which welding can be performed when the two fixing plates 2 clamp the steel plate.
