DETAILED DESCRIPTION

[0026] 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.

[0027] The utility model provides a welding and fixing device for a seat bracket, comprising a fixing plate 1, support rods 2 are fixed at both ends of the top of the fixing plate 1, a rotating rod 4 is movably connected to the middle part of the top of the support rod 2, connecting rods 5 are fixed to the outer rings of both ends of the rotating rod 4, a seat bracket placement plate 6 is fixed to the top of the connecting rod 5, a rotating motor 3 is fixed to the top of one support rod 2, the output shaft end of the rotating motor 3 is fixedly connected to the end of the rotating rod 4 through a reducer; through the setting of the rotating motor 3, the rotation of the rotating motor 3 can drive the rotating rod 4 fixedly connected thereto to rotate, and the rotating rod 4 can drive the seat bracket placement plate 6 to rotate through the connecting rod 5 fixedly connected thereto, and the seat bracket placement plate 6 can be tilted under the action of the rotating motor 3, so that during the welding process, welding slag dropped on the seat bracket placement plate 6 can be separated from the seat bracket placement plate 6.

[0028] A fixing groove 16 is provided in the middle of one end of the rotating rod 4, and a rotating rod fixing structure is provided on the inner side of the top end of the supporting rod 2 near the fixing groove 16. The rotating rod fixing structure includes a fixing block 14 and a movable block 13 fixed to the supporting rod 2, and the fixing block 14 is L-shaped, and the movable block 13 is C-shaped. The top of the movable block 13 is adapted to the fixing groove 16, and the middle part of the movable block 13 is fixedly connected to the vertical end of the fixing block 14 through a spring 20. A positioning rod 15 is fixed to one side of the bottom end of the movable block 13, and the other end of the positioning rod 15 is movably connected to one side of the horizontal end of the fixed block 14. An electromagnet 2 18 is fixed to the other side of the bottom end of the movable block 13, and an electromagnet 19 is fixed to the side of the horizontal end of the fixed block 14 away from the positioning rod 15, and the spring 20 is in a contracted state. When both the electromagnet 19 and the electromagnet 2 18 are not energized, the top of the movable block 13 is inserted into the fixing groove 16, and the rotating rod fixing structure positions the rotating rod 4 to prevent the rotating rod 4 from rotating.

[0029] From the above description of the rotating rod fixing structure, it can be known that when electromagnet 19 and electromagnet 2 18 are both energized and electromagnet 19 and electromagnet 2 18 are in a state of magnetic repulsion, the movable block 13 can move away from the fixed block 14, and the movable block 13 gradually moves away from the rotating rod 4 until the movable block 13 is completely separated from the rotating rod 4. At this time, the rotating rod 4 can rotate, which is convenient for cleaning the welding slag dropped on the seat bracket placement plate 6; when electromagnet 19 and electromagnet 2 18 are both in a power-off state, the rebound force of the spring 20 drives the movable block 13 to reset, and the top end of the movable block 13 can be reinserted into the inner cavity of the fixed groove 16.

[0030] One end of the seat support plate 6 is connected to the seat support limit block 7 by a bolt 8, and the seat support limit block 7 is an inverted U-shape, the middle part of the seat support limit block 7 contacts the top of the seat support plate 6, and one vertical end of the seat support limit block 7 contacts the side wall of the seat support plate 6, the other vertical end of the seat support limit block 7 is separated from the seat support plate 6, and the middle part of the other vertical end of the seat support limit block 7 is threadedly connected with a bolt 8, and an anti-slip pad is fixed to one end of the bolt 8 close to the seat support plate 6, and the material of the anti-slip pad can be rubber; from the description of the seat support limit block 7, it can be seen that by screwing the bolt 8, the seat support limit block 7 can be quickly fixed or separated from the seat support plate 6, so as to facilitate the change of the position of the seat support limit block 7.

[0031] Three slide grooves are provided in the middle of the top of the seat bracket placement plate 6, and a transmission structure 2 10 is provided in the inner cavity of the middle slide groove, and a transmission structure 1 9 is provided in the other two slide grooves; the transmission structure 1 9 and the transmission structure 2 10 both include two synchronous sprockets 25 and a synchronous chain 23, and synchronous sprockets 25 are movable at both ends of the inner cavity of the slide groove, and the two synchronous sprockets 25 are connected by the synchronous chain 23. A synchronous belt 24 is fixed on the outer surface of the synchronous chain 23. Through the setting of the synchronous belt 24, the synchronous belt 24 can shield the synchronous chain 23 to prevent welding slag from falling into the synchronous chain 23 and preventing welding slag from affecting the rotation of the synchronous chain 23.

[0032] A fixed round rod 11 is fixed to the top of the synchronous chain 23, and the bottom of the fixed round rod 11 is located at the top of the inner cavity of the slide groove. In this way, the rotation of the synchronous belt 24 will not affect the seat bracket placed on the seat bracket placement plate 6, and the synchronous belt 24 can drive the fixed round rod 11 to rotate when it rotates. The top of the fixed round rod 11 is fixedly connected to the bottom of the clamping plate 12. The two clamping plates 12 are symmetrically arranged on the seat bracket placement plate 6. The clamping plates 12 and the seat bracket limit blocks 7 are in a mutually perpendicular state, and the clamping plates 12 are located above the seat bracket limit blocks 7.

[0033] From the above description of the clamping plates 12 and the seat bracket limit blocks 7, it can be seen that the two clamping plates 12 can clamp and fix the seat brackets to facilitate the welding of the seat brackets, and the seat bracket limit blocks 7 can position the seat brackets so that the same batch of seat brackets can be placed at the correct position on the seat bracket placement plate 6, thereby improving the seat bracket fixing efficiency and facilitating the processing of the seat brackets.

[0034] The two clamping plates 12 in the present application move in opposite directions. A moving block 21 is fixed to one end of the inner surface of the synchronous chain 23 in the transmission structure 10. The moving block 21 is fixedly connected to one end of the electric telescopic rod 12. The other end of the electric telescopic rod 12 is fixedly connected to the seat support placement plate 6. A moving rod 26 is fixed to one end of the inner surface of the synchronous chain 23 in the transmission structure 19. The middle part of the moving rod 26 is fixedly connected to one end of the electric telescopic rod 17. The other end of the electric telescopic rod 17 is fixedly connected to the seat support placement plate 6. Through the setting of the electric telescopic rod 12, the extension and retraction of the electric telescopic rod 12 can drive the moving block 21 fixed thereto to move. The synchronous chain 23 fixedly connected thereto rotates. When the synchronous chain 23 moves, it drives the clamping plate 12 connected thereto to move. Similarly, the extension and retraction of the electric telescopic rod 17 can drive the clamping plate 12 on the transmission structure 9 to move through the moving rod 26. The coordinated use of the two clamping plates 12 can achieve the clamping and fixing of the seat support.

[0035] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0036] In summary, when the seat bracket welding and fixing device is used, the seat bracket is placed on the seat bracket placement plate 6, and the seat bracket is clamped and fixed by two clamping plates 12. The staff adjusts the position of the seat bracket limit block 7 so that the seat bracket limit block 7 contacts the end of the seat bracket, and the position of the seat bracket limit block 7 is fixed by bolts 8, so that the seat brackets of the same batch can be placed at the correct position on the seat bracket placement plate 6, thereby improving the efficiency of clamping and fixing the seat brackets, and also making the processing position consistency of the seat brackets of the same batch good. After the seat bracket is welded, the two clamping plates 12 move in the opposite direction. After the seat bracket is removed, the electromagnet 1 19 and the electromagnet 2 18 are both in the energized state. The repulsive force generated by the electromagnet 1 19 and the electromagnet 2 18 when both are energized pushes the movable block 13 away from the rotating rod 4 until the movable block 13 is separated from the rotating rod 4, and the rotating motor 3 works, and the rotating motor 3 drives the seat bracket placement plate 6 to rotate. The welding slag dropped from the seat bracket placement plate 6 is separated from the seat bracket placement plate 6 under the action of gravity, which is convenient for the reuse of the welding and fixing device.
