It requires power to be driven by a contact network or power rails. It is primarily used for rail transportation between cities of all sizes.
[0003] Nowadays, when disassembling the motor hanger leaf spring and parallel pin complementarily in the electric multiple unit, multiple workers are required to disassemble them at the same time. When disassembling the motor hanger leaf spring and parallel pin, multiple workers are required to position them and then dispatch workers to disassemble them, which greatly increases the labor cost and has poor use effect. In order to solve the above problems, there is an urgent need for an electric multiple unit motor hanger leaf spring parallel pin disassembly tool to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] See also Figure 1-5 The utility model provides a technical solution: a tool for disassembling parallel pins of leaf springs of motor hangers of electric multiple units, comprising a tool base 1, a groove 2 is provided on the top surface of the tool base 1, a partition 3 is fixedly installed on the top surface of the tool base 1, a positioning component 4 is provided on the top of the tool base 1, and a reinforcement component 5 is provided on the positioning component 4;
[0029] The positioning assembly 4 includes a forward and reverse motor 41, which is fixedly mounted on the side wall of the tooling base 1. A power rod 42 is fixedly mounted on one end of the output shaft of the forward and reverse motor 41, and a first threaded rod 43 is fixedly mounted on the other end of the power rod 42. A transmission rod 44 is fixedly mounted on the other end of the first threaded rod 43.
[0030] A second threaded rod 45 is fixedly mounted on the other end of the transmission rod 44. A threaded ring 46 is threadedly mounted on the outer walls of the first threaded rod 43 and the second threaded rod 45. A connecting rod 47 is fixedly mounted on the outer wall of the threaded ring 46. A first clamping plate 48 and a second clamping plate 49 are fixedly mounted on the top of the connecting rod 47. A travel groove is provided on the top surface of the tooling base 1, and the inner wall of the travel groove is slidably connected to the connecting rod 47.
[0031] The specific implementation method is as follows: the motor hanger leaf spring is placed on the tooling base 1 so that the bottom of the leaf spring fits onto the partition 3, and at the same time, the buckle tied on the leaf spring coincides with the groove 2, thereby ensuring that the leaf spring fits onto the tooling base 1, and then the forward and reverse motor 41 is started, and one end of the output shaft of the forward and reverse motor 41 drives the power rod 42 to rotate, and the power rod 42 drives the first threaded rod 43 to rotate. While the first threaded rod 43 rotates, the second threaded rod 45 is driven to rotate through the transmission rod 44. The outer walls of the first threaded rod 43 and the second threaded rod 45 are threadedly installed with a threaded ring 46. When the first threaded rod 43 and the second threaded rod 45 rotate, the threaded ring 46 is driven to move on its outer wall. The threaded ring 46 drives the first clamping plate 48 and the second clamping plate 49 to move respectively through the connecting rod 47. Because the threads on the first threaded rod 43 and the second threaded rod 45 are in opposite directions, the first clamping plate 48 and the second clamping plate 49 are displaced toward each other, and the leaf spring is clamped, and the motor hanger leaf spring and the parallel pin can be disassembled.
[0032] The reinforcement assembly 5 includes an insert plate 51, which is fixedly mounted on the top of the second clamping plate 49. The outer wall of the insert plate 51 is provided with a mounting groove, the inner wall of the mounting groove is provided with a spring rod 52, and both ends of the spring rod 52 are fixedly mounted with a latch 53. The outer wall of the first clamping plate 48 is provided with a slot 54, and the inner wall of the slot 54 is provided with a pin hole 55.
[0033] The specific implementation method is as follows: when the first splint 48 and the second splint 49 are displaced toward each other, the plug plate 51 provided on the second splint 49 is inserted into the slot 54 provided on the first splint 48, and the pin 53 provided on the plug plate 51 is initially squeezed by the inner wall of the slot 54, so that the pin 53 is retracted into the installation groove on the plug plate 51, and the pin 53 also squeezes the spring rod 52 to form a compressed state. When the plug plate 51 is fully inserted into the slot 54, the pin 53 will be on the same horizontal line as the pin hole 55 provided on the inner wall of the slot 54. The pin 53 is no longer squeezed and pops out of the installation groove by the elastic force of the spring rod 52, so that it is stuck in the pin hole 55.
[0034] Working principle: Place the motor hanger leaf spring on the tooling base 1 so that the bottom of the leaf spring fits onto the partition 3, and at the same time, the buckle tied to the leaf spring coincides with the groove 2, thereby ensuring that the leaf spring fits onto the tooling base 1, and then start the forward and reverse motor 41, and one end of the output shaft of the forward and reverse motor 41 drives the power rod 42 to rotate, and the power rod 42 drives the first threaded rod 43 to rotate. When the first threaded rod 43 rotates, it drives the second threaded rod 45 to rotate through the transmission rod 44. Threaded rings 46 are threadedly installed on the outer walls of the first threaded rod 43 and the second threaded rod 45. When the first threaded rod 43 and the second threaded rod 45 rotate, they drive the threaded ring 46 to move on their outer walls, and the threaded ring 46 drives the first splint 48 and the second splint 49 to move respectively through the connecting rod 47. The threads on them are in opposite directions, so that the first clamping plate 48 and the second clamping plate 49 are displaced toward each other, and the leaf spring is clamped, and the motor hanger leaf spring and the parallel pin can be disassembled. When the first clamping plate 48 and the second clamping plate 49 are displaced toward each other, the plug plate 51 provided on the second clamping plate 49 is inserted into the slot 54 provided on the first clamping plate 48, and the latch 53 provided on the plug plate 51 is initially squeezed by the inner wall of the slot 54, so that the latch 53 is retracted into the mounting groove on the plug plate 51, and the latch 53 also squeezes the spring rod 52 to form a compressed state. When the plug plate 51 is fully inserted into the slot 54, the latch 53 will be on the same horizontal line as the pin hole 55 provided on the inner wall of the slot 54, and the latch 53 is no longer squeezed and pops out from the mounting groove by the elastic force of the spring rod 52, so that it is stuck in the pin hole 55.
[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
