Description

Technical Field

[0001] The utility model relates to the technical field of traction motor experiments, in particular to a test bench for traction motors. Background Art

[0002] In the current urban transportation system, subway trains are becoming increasingly important because they do not occupy urban ground land. Subway train routes largely pass through the city center, of which underground routes account for a relatively high proportion. Subway trains are characterized by high operating intensity and frequent round trips. In addition, the vehicles run at high speeds and carry many passengers. The traction motors of subway trains are under great working pressure and are prone to various faults. Faulty subway train traction motors pose safety hazards and may cause accidents during operation. Therefore, it is necessary to regularly inspect and repair the traction motors of subway trains to ensure the normal operation of subway trains.

[0003] However, in actual use, the prior art usually uses a motor fixing seat to fix the motor thread on the test bench. However, when fixing motors of different sizes, the threaded holes on the motor fixing seat and the test bench must be consistent, which makes it difficult to fix motors of different specifications and inconvenient to use.

[0030] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0031] The utility model provides a test bench for a traction motor, comprising:

[0032] Test bench 1;

[0033] A through hole 2 is symmetrically formed on the test bench 1;

[0034] A sliding block 3 is slidably installed in the through hole 2;

[0035] A thread groove 4 is formed on the upper end surface of the sliding block 3;

[0036] A driving assembly, arranged in the test bench 1, for driving a pair of sliding blocks 3 to move;

[0037] Under the action of the driving assembly, a pair of sliding blocks 3 can be driven to move so that they can move closer to or farther away from each other, making it convenient for workers to thread external bolts into the thread groove 4 to fix traction motors of different sizes.

[0038] Specifically, the drive components include;

[0039] The screw rods 5 are two in number and are both rotatably mounted in the test bench 1 and are both threadedly connected to a pair of sliding blocks 3;

[0040] The pair of screw rods 5 rotate to drive the pair of sliding blocks 3 to move closer to or farther from each other;

[0041] There are two sprockets 6, both of which are arranged on one side of the test bench 1 and are fixedly connected to one end of a pair of screw rods 5 respectively;

[0042] The chain 7 is meshed and connected with a pair of sprocket wheels 6;

[0043] Under the action of the chain 7 and the pair of sprocket wheels 6, the pair of screw rods 5 can rotate at the same speed, so as to drive the pair of sliding blocks 3;

[0044] The rotating plate 8 is disposed on one side of the test bench 1 and is fixedly connected to one end of a screw rod 5;

[0045] The rotation of the rotating plate 8 can drive one screw rod 5 to rotate, and at the same time, under the action of a pair of sprocket wheels 6 and a chain 7, another screw rod 5 can be rotated at the same time;

[0046] A locking mechanism, provided on a side wall of the test bench 1, for locking the rotating plate 8;

[0047] Under the action of the locking mechanism, the rotation position of the rotating plate 8 can be locked to prevent it from rotating.

[0048] Specifically, the locking mechanism includes:

[0049] A locking groove 9 is formed in a ring shape on one side wall of the test bench 1;

[0050] A sliding hole 10 is formed in the rotating plate 8;

[0051] The locking pin 11 is slidably installed in the sliding hole 10, and one end of the locking pin is plugged into the locking groove 9;

[0052] One end of the locking pin 11 is plugged into the locking groove 9, which can fix the rotation position of the rotating plate 8 to prevent the rotating plate 8 from driving the screw 5 to rotate due to external reasons, thereby loosening the traction motor fixed on the sliding block 3;

[0053] The elastic member 12 is wound around the outer surface of the locking pin 11, and one end is welded to the outer surface of the locking pin 11, and the other end is welded to the inner wall surface of the sliding hole 10;

[0054] Under the action of the elastic member 12 , a force acting on the locking pin 11 toward the locking groove 9 can be applied to the locking pin 11 , so that one end of the locking pin 11 is always inserted into the locking groove 9 .

[0055] Specifically, a slide groove 13 is formed on the inner wall surface of the through hole 2, and a slider 14 slidably connected to the slide groove 13 is fixedly mounted on one side wall surface of the sliding block 3;

[0056] Under the action of the sliding groove 13 and the sliding block 14 , the sliding block 3 can slide more stably in the through hole 2 .

[0057] Specifically, the screw rod 5 is a bidirectional threaded rod.

[0058] Specifically, the elastic member 12 is a tension spring.

[0059] Working principle: First, the staff pulls out the locking pin 11 to disengage one end of it from the locking groove 9, and rotates the rotating plate 8 at the same time. The rotation of the rotating plate 8 drives a screw rod 5 to rotate. Under the action of a pair of sprockets 6 and a chain 7, another screw rod 5 rotates at the same time. At this time, the rotation of the pair of screw rods 5 can respectively drive a pair of sliding blocks 3 to slide in a pair of through holes 2. The position of the sliding block 3 in the through hole 2 can be adjusted to match the size of the traction motor. At this time, the staff uses external bolts to thread the thread groove 4 to fix the traction motor on the pair of sliding blocks 3. At this time, the staff loosens the locking pin 11, and the elastic member 12 applies a force to the locking pin 11, so that one end of it is inserted into the locking groove 9, and the rotation position of the rotating plate 8 is locked to prevent external factors from causing the rotating plate 8 to rotate, thereby completing the fixation of the traction motor, making it convenient for the staff to inspect and repair the traction motor, and bringing convenience to people.
