Detailed Description
The utility model will be described in further detail with reference to specific embodiments and drawings.
A brake shoe plug welding fixture as shown in figures 1-2 is used for welding connection of an arc-shaped plate and a rib plate of a brake shoe. The fixture comprises a base 1 fixedly arranged on a welding machine tool, a lower die 2 is fixedly arranged on the base 1, the lower die 2 is used for positioning two rib plates, first positioning columns 8 are respectively arranged on two sides of the front portion of the lower die 2, and second positioning columns 9 are respectively arranged on two sides of the rear portion of the lower die 2. The opposite inner sides of the two rib plates are clung to the side wall of the lower die 2, and the circular arc positioning grooves at the two ends of the rib plates are respectively positioned on the first positioning column 8 and the second positioning column 9. The left side and the right side of the lower die 2 are respectively provided with a support column 4, the opposite inner sides of the middle parts of the two support columns 4 are respectively provided with a side die 7 which moves horizontally, and the two side dies 7 which move relatively are used for pressing the rib plates on the lower die 2.
The rear part of the lower die 2 is provided with an arc plate positioning part for positioning the end part of the arc plate. The upper part of one of the support columns 4 is provided with a positioning pressing block 5 on the opposite inner side for positioning the side surface of the arc plate. As shown in fig. 1, the positioning pressing block 5 is fixed on the support column 4 through a bolt, and an adjusting cushion block 10 is arranged between the positioning pressing block 5 and the support column 4. The opposite inner side of the upper part of the other support column 4 is provided with an elastic pressing block 6, the elastic pressing block 6 is connected to the support column 4 through a bolt, and a compression spring 11 is arranged between the elastic pressing block 6 and the support column 4. The elastic pressing block 6 is pressed against the positioning pressing block 5 by the action of the compression spring 11.
The rear end of the base 1 is hinged with an upper die 3, and the upper die 3 is provided with an arc-shaped pressing part which is opposite to the lower die 2. After the workpiece is positioned, the upper die 3 is turned over to enable the arc-shaped pressing part of the workpiece to be clung to the outer side of the arc-shaped plate, so that the arc-shaped plate is fully contacted with the arc edge of the rib plate. In order to prevent uneven pressing of tilting of one side of the arc plate, a balance adjusting press head 13 which is arranged symmetrically left and right is arranged on the upper die 3. The balance adjusting pressure heads are connected to the upper die 3 through threads, and the two balance pressure heads 13 can be in contact with the arc-shaped plate through thread adjustment.
In order to prevent the problem of poor positioning accuracy caused by displacement of the positioning press block 5 when the side die 7 is pressed, the side die 7 in the embodiment is provided with a guide post 12 penetrating through the support post 4, and the side die 7 is connected with a hydraulic cylinder through the guide post 12. The hydraulic cylinder is fixedly connected to the welding machine tool, and the support column 4 only plays a role in guiding the side die 7.
The foregoing has described in detail the technical solutions provided by the embodiments of the present utility model, and specific examples have been applied to illustrate the principles and implementations of the embodiments of the present utility model, where the above description of the embodiments is only suitable for helping to understand the principles of the embodiments of the present utility model; meanwhile, as for those skilled in the art, according to the embodiments of the present utility model, there are variations in the specific embodiments and the application scope, and the present description should not be construed as limiting the present utility model.
