Technical Field

[0001] This utility model relates to the field of machine tool maintenance technology, specifically to a tester for machine tool maintenance. Background Technology

[0002] A tester for machine tool maintenance is a tool used to test and repair the electrical system of a machine tool. It can help technicians quickly determine the continuity of the circuit, the location of the fault, and parameters such as voltage and current, ensuring that the motor wiring is correct and preventing equipment damage caused by incorrect phase sequence. When using these testers, it is essential to follow the safe operating procedures and ensure that the equipment is in a safe state to prevent electric shock or equipment damage.

[0003] Chinese Patent Publication No. CN220525962U relates to the technical field of relay testers for electricity meters, and discloses a relay tester including a housing structure. The housing structure includes a top cover and a bottom cover. A module component is fixedly installed inside the bottom cover. A control display component is fixedly installed on the front of the bottom cover, and a power input socket is fixedly installed on the rear side of the bottom cover. This relay tester automates relay testing. It allows for automatic continuity testing by preset relay drive counts and monitors the relay contact closure. When the drive count matches the actual contact closure count, the test is considered normal; otherwise, it is considered abnormal. The relay drive pulse width can be flexibly set via a touchscreen to meet the requirements of different relay models, or the minimum drive pulse width at a certain voltage value can be tested by adjusting the pulse width.

[0004] However, this utility model has the following problems in actual use:

[0005] 1. Most of the existing test pen connectors are snap-fit ​​interfaces. During the use of the equipment, the connectors may become loose, which is not conducive to the connection of the equipment connectors and reduces the reliability of the equipment to a certain extent.

[0006] 2. Most of the existing test pen tips are fixed. When testing electrical components deep inside machine tools, it may be difficult for the test pen to reach the target location, making it inconvenient to perform electrical tests quickly and affecting the convenience of the equipment to some extent.

It can also measure the resistance of circuits to help determine whether components are normal. The device can be carried by the handle 12, and the support feet 13 can prevent the main body box 11 from directly contacting the ground.

[0037] Please see Figure 1 and Figure 4 The connecting mechanism 3 includes an interface 31, and the interface 31 is configured as two sets. The outer surface of one end of the two sets of interfaces 31 is fixedly connected to the outer surface of one side of the main body box 11. The outer surface of the interface 31 is threadedly connected to a connector 32, and both sides of the outer surface of the connector 32 are fixedly connected to a fixing block 33.

[0038] When the connector 32 is rotated clockwise, it can be tightened onto the outer surface of the interface 31. Then, the mating bolt 35 is rotated and tightened until it abuts against the outer surface of the main body box 11. The reaction force of the fixing block 33 can press the connector 32 against it to prevent it from loosening and rotating. When the connector 32 is rotated counterclockwise, the interface 31 and the connector 32 can be separated.

A test pen tip 44 is inserted into the inner surface of one end of the outer surface of the test pen body 42. A fixing hole 45 is opened in the inner bottom of the outer surface of one side of the test pen tip 44. A connecting hole 46 is opened in the inner surface of one side of the outer surface of the test pen body 42. A fixing bolt 47 is threadedly connected to the inner surface of the connecting hole 46. The outer surface of one end of the fixing bolt 47 is inserted into the inner surface of the fixing hole 45.

[0040] The outer surfaces of the test pen tip 44 and the test pen body 42 are respectively provided with a limiting strip and a limiting groove. During the insertion of the test pen tip 44, the limiting strip can be inserted into the limiting groove to prevent the fixing hole 45 from being misaligned. After the test pen tip 44 is inserted to the bottom, the fixing hole 45 and the connecting hole 46 are on the same straight line. Then the fixing bolt 47 can be rotated and inserted into the interior of the connecting hole 46. The fixing bolt 47 passes through the interior of the fixing hole 45 to fix the test pen tip 44. The test pen 4 is connected to the test instrument 1 through the wire 41.
