AI Technical Summary
The existing railway signal relay intelligent test bench cannot effectively fix the relay, which leads to easy displacement or vibration during the test, which leads to inaccurate or unstable test results.
An intelligent test bench including a test bench, a two-way cylinder and a clamping plate is designed. Through the cooperation of the two-way cylinder and the clamping plate, the relay can be quickly fixed, and the relay can be quickly fixed through fixed components (such as connecting plates, mounting plates, limit rods, Linear bearings, retaining plates, threaded sleeves, screws and bearing housings) further ensure the relay remains stable during testing.
Through this design, the displacement and vibration of the relay during the test can be effectively avoided, ensuring the accuracy and stability of the test results, and improving the overall quality of the test.

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0013] See also Figure 1-2 The utility model provides an intelligent test bench for railway signal relays, including a test bench 1, a bidirectional cylinder 2 and two clamping plates 3. The test bench 1 is provided with two openings, the bidirectional cylinder 2 is arranged at the bottom of the test bench 1, and the two clamping plates 3 are respectively movable through the two openings of the test bench 1. The two driving ends of the bidirectional cylinder 2 are respectively connected to the two clamping plates 3, and two fixing components 4 are arranged on the two clamping plates 3.
[0014] Specifically, the fixing assembly 4 includes a connecting plate 41, a mounting plate 42, two limit rods 43, two linear bearings 44, a fixing plate 45, a threaded sleeve 46, a screw 47 and a bearing seat 48. The connecting plate 41 is arranged at the top of the clamping plate 3, the mounting plate 42 is arranged on one side of the connecting plate 41, the two limit rods 43 are connected to the top of the mounting plate 42 through two linear bearings 44, the fixing plate 45 is arranged at the bottom end of the two limit rods 43, the threaded sleeve 46 is arranged at the top of the mounting plate 42, the screw 47 is connected to the threaded sleeve 46, the bearing seat 48 is arranged at the top of the fixing plate 45, and the bottom end of the screw 47 is interference fit with the inner ring of the bearing seat 48.
[0015] Specifically, a rubber pad 49 is provided at the bottom of the fixing plate 45 .
[0016] Working principle: When testing the relay, the staff places the relay on the test bench 1 and turns on the two-way cylinder 2. The two driving ends of the two-way cylinder 2 will drive the two clamping plates 3 to retract inward, thereby clamping and fixing the relay. Then the staff turns the screw 47 downward. Due to the limiting effect of the limit rod 43 and the bearing seat 48, the fixing plate 45 will move downward in a straight line, thereby further fixing the relay.
