Description

Technical Field

[0001] The utility model relates to a side top plate processing tool, in particular to a side top plate processing tool for a rail vehicle. Background Art

[0002] The side roof panel is a key component of rail vehicle interior components, running through the entire roof of the vehicle. The side roof panels in the door area, window area, and end sections have different structures. The entire train has approximately 120 pieces in more than 10 specifications. The arc of the side roof panel profile is inserted into the hinge profile slot to control the opening state of the side roof panel. To limit the lateral displacement of the hinge profile and the side roof panel profile and enable the side roof panel to open flexibly, hinge fixing seats are installed at designated positions on the side roof panel and hinge profile for positioning. This requires machining the fixing holes for the hinge fixing seats at the arc position of the side roof panel profile. A plane needs to be set when machining the holes. However, the side roof panel profile has an irregular cross-section structure, making it impossible to locate the machining plane. This necessitates the design of a tooling that can machine to the arc position of the profile. Utility Model Content

The two side top plate bases 1 are both arranged on a workbench 5 with a T-slot 4. A first support platform 6 is provided on the workbench 5 at the left side of each side top plate base 1, and a second support platform 7 is provided on the workbench 5 at the right side of each side top plate base 1.

[0029] The first support platform 6 and the second support platform 7 are both stepped support platforms. One end of the first pressure plate 8 is set on the low-level table surface on the first support platform 6, and the other end extends above the left end position of the corresponding side top plate base 1, and the side top plate 15 to be processed is fixed on the side top plate base 1 through the first pad 9.

[0030] One end of the second pressing plate 10 is set on the low-level table surface on the second supporting platform 7, and the other end extends above the right end position of the corresponding side top plate base 1, and the side top plate to be processed is fixed on the side top plate base 1 through the second pad 11.

[0031] The high-level columns can limit the outside of the corresponding first pressure plate 8 or the second pressure plate 10. The low-level table heights on the first support platform 6 and the second support platform 7 are higher than the end heights of the corresponding side top plate base 1, so as to limit the end of the side top plate 15 to be processed.

[0032] The first pad 9 is arranged between the first pressure plate 8 and the top plate 15 on the side to be processed, and the second pad 11 is arranged between the second pressure plate 10 and the top plate on the side to be processed. The upper end surfaces of the first pad 9 and the second pad 11 are in contact with the corresponding lower end surfaces of the first pressure plate 8 and the second pressure plate 10, and the lower end surfaces of the first pad 9 and the second pad 11 are in contact with the corresponding contact ends of the top plate 15 on the side to be processed.

[0033] The first pressing plate 8 and the second pressing plate 10 are both provided with long adjustment holes 12, and each long adjustment hole 12 is provided with a T-bolt 13. The wide head end of the T-bolt 13 is set in the T-slot 4 on the workbench 5, and the narrow head end passes through the upper end surface of the corresponding long adjustment hole 12, and the T-bolt 13 is fixed to the first pressing plate 8 or the second pressing plate 10 by using a fastening nut 14.

[0034] A gasket with a diameter larger than the width of the long adjustment hole 12 is provided between the first pressure plate 8 and the second pressure plate 10 and the corresponding fastening nuts 14 thereon, and the length direction of the long adjustment hole 12 is perpendicular to the length direction of the T-slot 4 on the workbench 5.

[0035] The process of using the overall technical solution formed by the above embodiments is as follows:

[0036] Select appropriate long screws 2 as needed to connect the two side top plate bases 1 to assemble into two sets of side top plate components, place the two sets of side top plate components on the workbench 5 respectively, and place the first support platform 6 and the second support platform 7 on both sides of each side top plate base 1 respectively, place the side top plate 15 to be processed stably on the two sets of side top plate components, and place the corresponding first pads 9 and the second pads 11 on both sides of the upper end surface of the side top plate 15 to be processed corresponding to the first support platform 6 and the second support platform 7 respectively, and place one end of the first pressing plate 8 on the first support platform 6. , and the other end is placed on the upper end surface of the first cushion block 9, and is pressed and fixed with the T-bolt 13 on the first pressing plate 8; then one end of the second pressing plate 10 is placed on the low step surface of the second support platform 7, and the other end is placed on the upper end surface of the second cushion block 11, and is pressed and fixed with the T-bolt 13 on the second pressing plate 10; after fixation, the top plate 15 on the side to be processed is firmly fixed without displacement, and then the fixing hole processing is performed on the top plate 15 on the side to be processed, which can accurately process the incision, improve production efficiency, and ensure product quality.

[0037] Example 2: The difference from Example 1 is that the side top plate 15 to be processed is too long, and two groups of side top plate assemblies are not enough. In order to ensure the stability of the side top plate 15 to be processed, three or more groups of side top plate assemblies are placed below the side top plate 15 to be processed, so that the extra-long side top plate 15 to be processed can be stably set on the side top plate assembly.
