Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle-mounted relays, in particular to a vehicle-mounted relay test bench. Background Art
[0002] In the vehicle electrical system, relays play a vital role. They are responsible for controlling the switching of current to ensure the normal operation of various electrical devices in the vehicle. To ensure the stable and reliable performance of vehicle relays, regular testing and maintenance are essential. However, the existing vehicle relay test bench mainly relies on manual operation when performing plug-in and pull-out tests.
[0003] This manual plug-in test method is not only inefficient, but also during the long and high-intensity test process, the tester may suffer from fatigue or improper operation, resulting in inaccurate test data, and may even damage the relay or test bench. In addition, manual operation also has safety hazards, such as improper operation may cause electric shock accidents. Utility Model Content
[0004] The purpose of the utility model is to provide a vehicle-mounted relay test bench to solve the problems raised in the above background technology.

[0006] Preferably, the fixing structure includes a threaded sleeve, a screw, a bearing, a fixing plate and two linear guide rods, the threaded sleeve is arranged on the left side of the groove, the screw and the threaded sleeve are threadedly connected, the inner ring of the bearing and the screw are interference fit, the left side of the fixing plate is connected to the bearing, the two linear guide rods are movably passed through the left side of the groove, and one end of the two linear guide rods is connected to the left side of the fixing plate.
[0007] Preferably, the bracket is an inverted concave-shaped structure.
[0008] Preferably, a handle is provided at one end of the screw rod, and the handle is provided with anti-slip grooves.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model can fix two relay bodies at the same time through two fixing structures, and after fixing, the cylinder drives the relay body to move downward, so as to connect with the socket, and then perform plug-in and pull-out tests. The utility model can test two relay bodies at the same time, and no manual operation is required during the test. First, this design greatly improves the test efficiency because it allows two relays to be tested at the same time, thereby reducing the test cycle, improving production efficiency, and reducing labor costs. Secondly, the degree of automation is high, no manual operation is required, the risk of manual intervention is reduced, and the accuracy and stability of the test are improved. In addition, the design saves space, has a compact structure, and occupies a small space. It can be easily integrated into the existing production line, which improves the utilization rate of the production site. At the same time, it also reduces production costs, because automated testing reduces manual operations, reduces labor costs, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] 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.
[0014] See also Figure 1-2The utility model provides a vehicle-mounted relay test bench, including a workbench 1, a bracket 2, two sockets 3, a cylinder 4, a connecting plate 5, two grooves 8, two fixed structures 6 and two relay bodies 7. The bracket 2 is arranged on the top of the workbench 1, the two sockets 3 are arranged on the top of the workbench 1, the cylinder 4 is arranged on the top of the bracket 2, and the driving end of the cylinder 4 movably passes through the top of the bracket 2, the connecting plate 5 is arranged at the driving end of the cylinder 4, the two grooves 8 are arranged at the bottom of the connecting plate 5, two fixed structures 6 are arranged on the two grooves 8, the two fixed structures 6 are arranged symmetrically, two relay bodies 7 are arranged between the two fixed structures 6 and the two grooves 8, and the positions of the relay bodies 7 and the sockets 3 correspond.
[0015] Specifically, the fixing structure 6 includes a threaded sleeve 61, a screw 62, a bearing 63, a fixing plate 64 and two linear guide rods 65. The threaded sleeve 61 is arranged on the left side of the groove 8. The screw 62 and the threaded sleeve 61 are threadedly connected. The inner ring of the bearing 63 and the screw 62 are interference fit. The left side of the fixing plate 64 is connected to the bearing 63. The two linear guide rods 65 are movable through the left side of the groove 8, and one end of the two linear guide rods 65 is connected to the left side of the fixing plate 64.
[0016] When the staff fixes the relay body 7, they rotate the screw 62 inwards. Due to the limiting effect of the linear guide rod 65 and the bearing 63, the fixing plate 64 can only move linearly inwards, thereby fixing the relay body 7. After fixing, the staff turns on the cylinder 4, and the driving end of the cylinder 4 drives the relay body 7 to move linearly downwards, so that the relay body 7 is connected to the socket 3, and then the plug-in test is carried out.
[0017] Specifically, the bracket 2 is an inverted concave structure.
[0018] Specifically, a handle is provided at one end of the screw rod 62, and anti-slip grooves are provided on the handle.
