Technical Field

[0001] The utility model relates to the technical field of frame longitudinal beam assembly, and particularly relates to a positioning tool for a frame longitudinal beam. Background Technique

[0002] In the process of processing and assembling the frame, the assembly of the frame assembly is crucial. The current main method for assembling the frame assembly is to first install cross beam connecting plates, suspension parts, etc. on the longitudinal beam, and then connect the cross beams between the longitudinal beams by welding, riveting, etc. During this period, a positioning tool is needed to position the left and right longitudinal beams to ensure the accurate assembly of the left and right longitudinal beams. When connecting the longitudinal beam and the cross beam of the frame, it is necessary to position and fix the longitudinal beam through the positioning tool of the frame longitudinal beam to ensure the riveting assembly quality of the cross beam and the longitudinal beam of the frame.

[0003] However, when the existing tooling is in use, most of them can only support the longitudinal beam. However, bolts and other parts are needed to connect the longitudinal beam during the assembly process. When multiple workers assemble at the same time, it is not convenient for the workers to pick up the parts, which will affect the assembly efficiency of the longitudinal beam and reduce the applicability of the tooling.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1-4As shown, a frame longitudinal beam positioning tool comprises a positioning tool body 1, the positioning tool body 1 can bear the longitudinal beam of the frame, so that the longitudinal beam will not move easily during the installation process, and the assembly of the longitudinal beam is effectively facilitated. The interior of the positioning tool body 1 is fixedly connected with a fixing rod 2, and the surface of the fixing rod 2 is slidably connected with a movable seat 3. Under this action, when the movable seat 3 moves, the fixing rod 2 guides it, so that the movable seat 3 is more stable when moving. The bottom of the movable seat 3 is fixedly connected with a universal wheel 4, and the number of the universal wheels 4 is several. Under this action, the movable seat 3 can be When moving, the universal wheel 4 can support the movable seat 3, so that the movable seat 3 is more stable when moving. The inner cavity of the movable seat 3 is rotatably connected with a spur gear 5. Positioning mechanisms 6 are installed on both sides of the spur gear 5. Under the action of the positioning mechanism 6, when the movable seat 3 needs to be fixed, the positioning mechanism 6 and the fixing rod 2 can be limited, so that the movable seat 3 will not move easily. The top of the movable seat 3 is bolted with a hydraulic cylinder 7, and the top of the hydraulic cylinder 7 is bolted with a fixed shell 8. A placement box 9 is arranged on the top of the fixed shell 8, and both sides of the bottom of the placement box 9 are fixedly connected with a movable frame 1 0, the cross-sectional shape of the movable frame 10 is a circular structure design, and the surface of the movable frame 10 is movably connected to the inner cavity of the fixed shell 8. Under this action, the placement box 9 can undertake the parts required for the assembly of the longitudinal beam, and with the cooperation of the movable seat 3, the placement box 9 can be easily moved to a suitable position, so that the staff can assemble the longitudinal beam more conveniently, and with the cooperation of the hydraulic cylinder 7, the height of the placement box 9 can be adjusted, which is further convenient for the staff to take the parts. One side of the top of the movable seat 3 is hinged with an electric telescopic rod 11, and the other end of the electric telescopic rod 11 is mutually connected with the bottom of the placement box 9. The hinged connection allows the placement box 9 to rotate when the parts in the inner cavity are far away from the staff, through the cooperation of the electric telescopic rod 11, when the movable frame 10 is stuck in the fixed shell 8, so that the placement box 9 can be rotated, thereby facilitating the movement of the parts inside the placement box 9, so that it is more convenient for the staff to take the parts. The inner cavity of the placement box 9 is installed with balls 12, and the number of balls 12 is several. When the placement box 9 is tilted, the balls 12 can reduce the friction between the parts and the inside of the placement box 9, so that the parts inside the placement box 9 can be moved more conveniently.

[0022] The positioning mechanism 6 includes a rack plate 61. One side of the rack plate 61 meshes with the spur gear 5. A clamping frame 62 is fixedly connected to the surface of the rack plate 61. One side of the clamping frame 62 is designed with a toothed structure. The surface of the clamping frame 62 is clamped with the surface of the fixed rod 2. Under this action, the connection between the clamping frame 62 and the fixed rod 2 can be made more stable. A compression spring 63 is fixedly connected to one side of the clamping frame 62. The other end of the compression spring 63 is fixedly connected to the inner wall of the movable seat 3. Under this action, when it is necessary to move the movable seat 3, the rack plate 61 is moved to drive the clamping frame 62 to disengage from the fixed rod 2, and then the movable seat 3 is moved. After moving to a suitable position, with the cooperation of the compression spring 63, the clamping frame 62 can be clamped with the fixed rod 2 again, so as to limit the movable seat 3, which is relatively convenient. One end of the rack plate 61 is fixedly connected to a connecting frame 13. The surface of the connecting frame 13 is slidably connected to the inner wall of the movable seat 3. Under this action, it is convenient for the staff to move the rack plate 61, so as to conveniently adjust the clamping frame 62.

[0023] It should be noted that: the technical features such as the positioning tooling body 1 and the hydraulic cylinder 7 proposed in this technical solution should be regarded as prior art. The specific structures, working principles, possible control methods and spatial layout methods of these technical features can be selected conventionally in this field, and this technical solution will not be further specifically elaborated.

[0024] Working principle: First, place the longitudinal beam to be assembled on the surface of the positioning tooling body 1, and then place the parts or tools required during assembly in the placement box 9. Immediately start the assembly. When parts are needed during the assembly process, the staff pushes the rack plate 61 to move through the connecting frame 13. Under the action of the rack plate 61, the spur gear 5 and the clamping frame 62 will be driven to move, so that the clamping frame 62 no longer contacts the fixed rod 2. Then, the position of the movable seat 3 is moved. After the adjustment is completed, release the connecting frame 13. With the cooperation of the compression spring 63, the clamping frame 62 contacts the fixed rod 2 to limit the movable seat 3. This not only facilitates the staff to pick up the parts, but also improves the assembly efficiency of the tooling. When the parts to be used are far away from the staff, turn on the electric telescopic rod 11. Under the action of the electric telescopic rod 11, the placement box 9 is dragged to rotate. With the cooperation of the fixed shell 8 and the movable frame 10, the placement box 9 rotates, so that the parts can move to the side close to the staff. Then the staff can pick up the parts and use them.
