[0020] The utility model will be further described below in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, a brake beam brake shoe disassembly and assembly device according to an embodiment of the utility model comprises a conveyor line 1 and a manipulator 2, wherein the conveyor line 1 is used to convey the brake beam 5, and the manipulator 2 is arranged on the side of the conveyor line 1, and the manipulator 2 comprises a base 21 and a first manipulator arm 22 and a second manipulator arm 23 arranged on the base 21, and a first clamp 24 for clamping the brake shoe 3 is provided at the end of the first manipulator arm 22, and a second clamp 25 for clamping the brake shoe latch 4 is provided at the end of the second manipulator arm 23, and the brake shoe latch 4 is also called a brake shoe sign.

[0022] The brake beam 5 is stably transported by the conveyor line 1. Multiple brake beams 5 are placed at the designated position of the conveyor line 1 and maintain the same spacing. Whenever the conveyor line 1 is paused, the brake beam 5 can be accurately transported to the working position. When the brake shoe 3 needs to be removed, the brake beam 5 is transported to the working site. The first mechanical arm 22 and the second mechanical arm 23 both act according to the preset program, so that the first clamp 24 and the second clamp 25 both move according to the preset trajectory and accurately reach the working position. The first clamp 24 on the first mechanical arm 22 clamps the brake shoe 3 on the brake beam 5 to keep the position of the brake shoe 3 unchanged. The second mechanical arm 23 drives the second clamp 25 to extract the brake shoe latch 4 according to the preset trajectory, and then places the brake shoe latch 4 at the designated collection position. The first mechanical arm 22 drives the first clamp 24 to place the brake shoe 3 at the designated collection position. The whole process does not require manual use of auxiliary tools to disassemble the brake shoe 3, which not only improves work efficiency, but also effectively reduces labor intensity.

[0023] When the brake shoe 3 needs to be installed, the brake beam 5 is transported to the work site, and the first robotic arm 22 and the second robotic arm 23 both operate according to the preset program, so that the first clamp 24 and the second clamp 25 both move according to the preset trajectory and grab the brake shoe 3 and the brake shoe pin 4 respectively. The first robotic arm 22 drives the first clamp 24 to move the brake shoe 3 to the specified position and keep it stationary, and the second robotic arm 23 drives the second clamp 25 to insert the brake shoe pin 4 according to the preset trajectory to fix the brake shoe 3 on the brake beam 5.

[0024] The first mechanical arm 22 and the second mechanical arm 23 are both fixed to the base 21 by bolts, which is convenient for installation and removal. The mechanical arms 2 are arranged on both sides of the conveyor line 1, so that the brake shoes 3 and brake shoe latches 4 on both sides of the brake beam 5 can be installed or removed at the same time, thereby improving work efficiency.

[0025] like Figure 2 As shown, one end of the first mechanical arm 22 away from the first clamp 24 is connected to the top surface of the base 21, and one end of the second mechanical arm 23 away from the second clamp 25 is connected to the side surface of the base 21. The first mechanical arm 22 and the second mechanical arm 23 are respectively arranged on different surfaces of the base 21, so that the first mechanical arm 22 and the second mechanical arm 23 each have enough space to move when working, and it is not easy to interfere. The first mechanical arm 22 and the second mechanical arm 23 share a base 21, which can save costs.

[0026] like Figure 1As shown, the height of the base 21 is higher than the height of the conveyor line 1. The first clamp 24 and the second clamp 25 are both facing downward when working, corresponding to the upward position of the brake shoe 3 and the brake shoe latch 4 on the brake beam 5, making it easier to complete the clamping work of the brake shoe 3 and the brake shoe latch 4. At the same time, more operating space is provided for the first mechanical arm 22 and the second mechanical arm 23.

[0027] like Figure 2 As shown, the first clamp 24 includes a first mounting seat 241 and two first clamping jaws 242. The two first clamping jaws 242 are arranged opposite to each other and can move on the first mounting seat 241. The two first clamping jaws 242 clamp and release the brake shoe 3 by moving toward and in the opposite direction, thereby grasping and transferring the brake shoe 3.

[0028] like Figure 2 As shown, the second clamp 25 includes a second mounting seat 251 and two second clamping jaws 252, and the two second clamping jaws 252 are arranged opposite to each other and can move on the second mounting seat 251. The two second clamping jaws 252 clamp and release the brake shoe latch 4 by moving toward and in the opposite direction, thereby grasping and transferring the brake shoe latch 4.

[0029] In this embodiment, the first clamp 24 and the second clamp 25 are both pneumatic fingers. Pneumatic fingers are finger-shaped clamping devices driven by air pressure. They have the following advantages:

[0030] High-precision positioning and clamping: Pneumatic finger grippers can quickly and accurately position and clamp workpieces of various shapes and sizes to ensure assembly accuracy and stability;

[0031] Adaptive adjustment: Through air pressure adjustment, the pneumatic finger gripper can adapt to workpieces of different sizes, without the need to frequently change the fixture, thus improving production efficiency;

[0032] High reliability: The pneumatic gripper adopts pneumatic control, which has high reliability and stability and can work continuously for a long time;

[0033] Easy to integrate and maintain: The pneumatic finger gripper has a simple structure and is easy to integrate into the automated assembly system, with low maintenance costs and long service life.

[0034] Since the volume of the brake shoe 3 is larger than the brake shoe pin 4, the size of the first clamp 24 in this embodiment is larger than the size of the second clamp 25. In order to ensure the clamping force, the first clamp 24 and the second clamp 25 are both provided with anti-slip patterns (not shown in the figure).

[0035] In this embodiment, the first mounting seat 241 is connected to the first mechanical arm 22 by bolts, so that the first clamp 24 can be easily replaced and maintained.

[0036] In this embodiment, the second mounting base 251 is connected to the second mechanical arm 23 by bolts, so that the second fixture 25 can be easily replaced and maintained.

[0037] In this embodiment, the first robot arm 22 and the second robot arm 23 are both six-axis robot arms, which can enable the first clamp 24 and the second clamp 25 to perform complex movements and accurately grasp the brake shoe 3 and the brake shoe latch 4.

[0038] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
