DETAILED DESCRIPTION

[0016] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0017] First, combine Figures 1 to 9 A spring assembly device for a high-speed railway brake pad according to an embodiment of the present invention is described, which is used for automatically assembling springs onto a high-speed railway brake pad and has a wide range of application scenarios.

[0018] like Figures 1 to 9 As shown, the spring assembly equipment for high-speed railway brake pads according to an embodiment of the present invention comprises: a pair of conveying modules 2, a spring assembly module 3 and a driving module.

[0019] Specifically, Figures 1 to 9 As shown, in this embodiment, a pair of conveying modules 2 are arranged in parallel with each other, and a pair of conveying modules 2 convey the high-speed rail brake pads 5 alternately, so as to realize continuous and uninterrupted conveyance of the high-speed rail brake pads 5 and improve efficiency; The spring assembly module 3 outputs the spring 1 and assembles the spring 1 on the high-speed rail brake pad 5 to realize the automatic assembly of the spring 1; The driving module is arranged above a pair of conveying modules 2, and the output end of the driving module is connected to the spring assembly module 3. The driving module drives the spring assembly module 3 to move back and forth between the pair of conveying modules 2, so that the spring assembly module 3 assembles the spring 1 of the high-speed rail brake pad 5 on the pair of conveying modules 2 to adapt to the installation positions of multiple springs 1 on the high-speed rail brake pad 5. The movement direction of the spring assembly module 3 is perpendicular to the conveying direction of the conveying module 2.

[0020] Specifically, Figures 1 to 9 As shown, in this embodiment, the spring assembly module 3 includes: a mounting frame 31, a spring material bin 32, an assembly mechanism 33 and a pushing mechanism 34; The mounting frame 31 is fixed to the output end of the driving module, and the mounting frame 31 fixes the spring bin 32, the assembly mechanism 33 and the pushing mechanism 34, providing a base for installation and fixing to improve stability; The spring bin 32 is vertically fixed on the mounting frame 31. The spring bin 32 stores and outputs the springs 1. The springs 1 in the spring bin 32 are automatically and continuously outputted by their own gravity. The pushing mechanism 34 is arranged at the bottom of the spring bin 32 and connected to the bottom of the spring bin 32. The pushing mechanism 34 receives the spring 1 output from the spring bin 32 and pushes the spring 1 output from the spring bin 32 to the assembling mechanism 33. The assembly mechanism 33 clamps the spring 1 pushed by the pushing mechanism 34, and pushes the spring 1 down to the high-speed rail brake pad 5. Due to the special shape of the spring 1, when the pushing mechanism 34 pushes the spring 1, the opening of the spring 1 needs to face the assembly mechanism 33. The spring 1 has elasticity, so that the spring 1 is clamped on the assembly mechanism 33 through its opening. The spring assembly module 3 occupies a small space, has a simple structure, and is easy to use.

[0021] Further, if Figures 1 to 9 As shown, in this embodiment, the spring magazine 32 includes: a cylinder 321, a positioning plate 322 and a detection sensor 323; The cylinder 321 is vertically fixed on the mounting frame 31, and the bottom of the cylinder 321 is connected to the pushing mechanism 34. The cylinder 321 stores and outputs the spring 1, and the spring 1 is stacked in the cylinder 321; The positioning plate 322 is vertically fixed in the cylinder 321. The positioning plate 322 positions the opening 11 of the spring 1. The positioning plate 322 ensures the consistency of the direction of the opening 11 of the spring 1, thereby ensuring the subsequent pushing and assembly actions. The thickness of the positioning plate 322 is smaller than the size of the opening 11 of the spring 1, thereby ensuring the smooth output of the spring 1. The detection sensor 323 is arranged on the side wall of the cylinder 321. The detection sensor 323 is used to detect the presence or absence of the spring 1. The installation position of the detection sensor 323 is close to the bottom of the cylinder 321.

The arc-shaped opening 345 positions and fixes the spring 1. When the pushing cylinder 342 pushes the receiving plate to receive the spring 1, the spring 1 falls into the arc-shaped opening 345. A long opening 346 is formed at the first end of the lower plate 344. The long opening 346 cooperates with the assembly mechanism 33. The assembly mechanism 33 moves in the long opening 346 to receive the spring 1 at the arc-shaped opening 345. The lower plate 344 supports the spring 1, and the opening size of the long opening 346 at one end close to the upper plate 343 is smaller than the maximum point of the arc-shaped opening 345, ensuring that the spring 1 will not fall along the long opening 346.

The clamping truncated cone 334 is adapted to the opening of the spring 1, and the clamping truncated cone 334 can be adapted to the circular shape in the middle of the opening of the spring 1. The bottom outer diameter of the clamping truncated cone 334 is larger than the top outer diameter and the diameter of the circular shape in the middle of the opening of the spring 1, so as to ensure that the spring 1 will not fall off; The compression sleeve 332 is sleeved on the clamping shaft 333; The pressing cylinder 331 drives the pressing sleeve 332 to press down to abut against the spring 1, and then continues to press down to push the spring 1 on the clamping shaft 333 to fall off the clamping round table 334 and clamp to the high-speed railway brake pad 5.

[0025] Specifically, Figures 1 to 9 As shown, in this embodiment, the conveying module 2 includes: a first linear motion module 21 and a positioning mechanism 22; The positioning mechanism 22 positions and fixes the high-speed rail brake pad 5 to ensure the stability of the high-speed rail brake pad 5 during transportation and assembly; The output end of the first linear motion module 21 is connected to the positioning mechanism 22 , and the first linear motion module 21 drives the positioning mechanism 22 and the high-speed rail brake pad 5 to move to just below the spring assembly module 3 , thereby realizing the transportation of the high-speed rail brake pad 5 .

[0026] Further, if Figures 1 to 9 As shown, in this embodiment, the positioning mechanism 22 includes: a supporting plate 221, a positioning shaft 222 and a pressing cylinder 223; The supporting plate 221 is connected to the output end of the first linear motion module 21, and the supporting plate 221 supports the high-speed rail brake pad 5; The positioning shaft 222 and the pressing cylinder 223 are arranged on the supporting plate 221; The positioning shaft 222 cooperates with the positioning hole on the high-speed rail brake pad 5 to realize the positioning of the high-speed rail brake pad 5. The number of the positioning shafts 222 can be set according to the number of the positioning holes; The clamping cylinder 223 presses and fixes the high-speed rail brake pad 5 to prevent the high-speed rail brake pad 5 from shifting and ensure the accuracy of the subsequent assembly process. The number of the clamping cylinders 223 is set to four, and the four clamping cylinders 223 are respectively arranged at the four corners of the supporting plate 221 to fix the high-speed rail brake pad 5 at multiple points.

[0027] Specifically, Figures 1 to 9 As shown, in this embodiment, the driving module includes: a second linear motion module 4, the output end of the second linear motion module 4 is connected to the spring assembly module 3, the second linear motion module 4 drives the spring assembly module 3 to move back and forth between a pair of conveying modules 2, and the second linear motion module 4 and the first linear motion module 21 are arranged perpendicular to each other.
