[0024] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a press-fitting tool for a brake spring cylinder for a locomotive:

[0025] The tool frame 1 comprises: a tool frame 1, a support box 2 is overlapped at the bottom of the front of the tool frame 1, a U-shaped slide rod 3 is slidably connected to the tail end of the top of the support box 2, a connecting plate 4 is fixedly connected to the middle of the U-shaped slide rod 3, the top of the connecting plate 4 is rotatably connected to a rotating table 5, one side of the rotating table 5 is fixedly connected to a baffle 6, the middle of the top of the support box 2 is rotatably connected to a rotating plate 7, the tail end of the top of the rotating plate 7 is provided with a square groove, the front end of the square groove is rotatably connected to a baffle 8, and the top of the baffle 8 is rotatably connected to the support Rod 9, the middle part of the square groove is fixedly connected with a snap ring 10, the front of the rotating plate 7 is rotatably connected with a slide groove 11, the tail ends of the surfaces of the two sets of U-shaped slide bars 3 are fixedly connected with a connecting rod 12, and the surface of the connecting rod 12 is slidably connected to the inner wall of the support box 2, the left and right ends of the connecting rod 12 are rotatably connected with rollers 13, the outer end of the connecting rod 12 is fixedly connected with a push plate 14, the front end of the inner wall of the tooling frame 1 is fixedly connected with a hydraulic cylinder 15, and the top end of the hydraulic cylinder 15 is rotatably connected with a turntable 16.

[0026] When the spring brake is assisted in press-fitting by this device, the spring brake is rolled to the front of the slide groove 11, and then the baffle 8 is pulled upward to rotate the baffle 8 to be perpendicular to the support box 2, and then the semicircular ring at the bottom end of the support rod 9 is placed on the snap ring 10, so that the baffle 8 is supported, and then the spring brake is pushed to the top of the rotating plate 7 through the slide groove 11, and the spring brake is moved into the arc groove at the top of the rotating plate 7, and the baffle 8 blocks the distance the spring brake moves, limiting the distance it rolls forward. The arc groove effectively limits the moving range of the spring brake, and at this time, the hydraulic cylinder 15 is injected with oil, so that the hydraulic cylinder 15 drives The rotating wheel 16 at the top extends and lifts the rotating plate 7, causing the rotating plate 7 to tilt slightly, and then the baffle 8 is lowered so that the baffle 8, the support rod 9 and the rotating plate 7 are at the same horizontal line, so that the spring brake rolls down to the rotating table 5, and the baffle 6 limits the rolling distance of the spring brake, and then the rotating table 5 is rotated so that it drives the spring brake to rotate to an angle suitable for press-fitting, and pushes the push plate 14 forward so that the push plate 14 drives the connecting rod 12 to move, and the connecting rod 12 drives the U-shaped slide bar 3 and the connecting plate 4 to move, and the connecting plate 4 drives the rotating table 5 to move to the bottom of the tooling frame 1, so that the tooling frame 1 can clamp the spring brake.

[0027] See also Figure 1 and Figure 5The left and right sides of the tooling frame 1 are fixedly connected to the first telescopic rod 17, the surface of the first telescopic rod 17 is slidably connected to the limit frame 18, the tail end of the inner wall of the limit frame 18 is slidably connected to the second telescopic rod 19, the tail end of the second telescopic rod 19 is fixedly connected to the rotating block 20, the tail end of the rotating block 20 is rotatably connected to the fixed block 21, and the horizontal longitudinal section of the fixed block 21 is a rectangle, the surface of the rotating block 20 is fixedly connected to the torsion spring 22, and the two ends of the torsion spring 22 are fixedly connected to the inner wall of the fixed block 21.

[0028] When fixing the support box 2 by using this device, the limit frame 18 is pulled outward, so that the first telescopic rod 17 extends out of the limit frame 18, and then the fixed block 21 is rotated so that the fixed block 21 squeezes the torsion spring 22 and rotates the fixed block 21 to the outside. Then, the limit frame 18 is inserted on both sides of the tooling frame 1, and the second telescopic rod 19 is pulled forward so that the second telescopic rod 19 drives the fixed block 21 to be at the tail end of the tooling frame 1. Then, the fixed block 21 is released, so that the torsion spring 22 rebounds and the torsion spring 22 drives the fixed block 21 to rotate, so that the fixed block 21 rotates to the inside of the tail end of the tooling frame 1, and then the tooling frame 1 is connected and fixed to the support box 2.

[0029] The working principle is to pull the limit frame 18 outward and rotate the fixed block 21, then insert the limit frame 18 into the left and right sides of the tooling frame 1, and loosen the fixed block 21 so that the fixed block 21 connects the tooling frame 1 with the support box 2, then roll the spring brake to the front of the slide groove 11 and then rotate the baffle 8 so that the baffle 8 is perpendicular to the rotating plate 7, then push the spring brake onto the rotating plate 7, so that the baffle 8 blocks the spring brake, reducing the spring brake from moving too fast and rolling out of the support box 2, then the baffle 8 is rotated in the opposite direction, and the hydraulic cylinder 15 is injected with oil again so that the hydraulic cylinder 15 lifts the rotating plate 7 to a certain angle, so that the spring brake slowly rolls down to the rotating table 5 and blocks the spring brake through the baffle rod 6, then rotates the rotating table 5 so that the spring brake rotates a specified angle, and then pushes the push plate 14 so that the connecting plate 4 moves the spring brake to the bottom of the tooling frame 1, thereby facilitating the tooling frame 1 to press the spring brake.
