Description

Technical Field

[0001] The utility model relates to the technical field of stator testing machines, in particular to an automatic stator testing machine. Background Art

[0002] By integrating multiple testing technologies and automated equipment, the automatic stator tester can automatically complete online inspection and testing of motor stators. It is primarily used to evaluate key parameters such as the stator's electrical characteristics, insulation performance, resistance, and inductance to ensure that the motor meets quality standards during the manufacturing process and maintains stable operation during subsequent use.

[0003] The operating table of the automatic stator tester is attached to a protective cover that slides over the stator of the motor under test. This is because the machine's operation may generate high-speed rotating parts or material fragments. The protective cover effectively blocks these dangerous materials from flying out, reducing the risk of accidental injury to the operator and ensuring workplace safety. Furthermore, the protective cover effectively isolates the operator from the moving parts of the machine, preventing possible injuries from direct contact, thereby ensuring safety during operation.

[0004] However, the existence of the protective cover makes it difficult to inspect and repair the equipment on the operating table of the automatic stator testing machine, and the protective cover needs to be removed, which is very cumbersome. Therefore, we propose an automatic stator testing machine. Utility Model Content

[0020] The following will be combined with the 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.

[0021] Example 1: Please refer to Figure 1-Figure 5 The figure shows an automatic stator testing machine, including a body 1 and an operating table 2 installed on the body 1, with connecting columns 3 fixedly connected to the rear edges of both sides of the upper end of the operating table 2, and a connecting rod 4 fixedly connected between the outer walls of the two connecting columns 3 near the upper edges, and two sliders 15 slidingly sleeved on the outer wall of the connecting rod 4, and the upper ends of the two sliders 15 are commonly fixedly connected to a rectangular plate 5, and a splicing plate 10 is fixedly connected to one side wall of the rectangular plate 5, and a transparent protective shell 6 is hinged at the front end of the rectangular plate 5, a fixing mechanism is provided between the transparent protective shell 6 and the splicing plate 10, and a transparent protective cover 7 is attached to the inner wall of the transparent protective shell 6, a locking member is provided between the transparent protective cover 7 and the transparent protective shell 6, and a handle 9 is fixedly connected to the middle part of the front end of the transparent protective shell 6.

[0022] See also Figure 2-Figure 5 The fixing mechanism shown in the figure includes a cylinder 11 and a socket 20. The cylinder 11 is fixedly connected to the side wall of the splicing plate 10 away from the rectangular plate 5, and a column 13 is movably passed through the cylinder 11 and the splicing plate 10. The end of the column 13 away from the splicing plate 10 is fixedly connected to the pull plate 12, and an elastic member is provided between the column 13 and the cylinder 11. The socket 20 is opened on the side wall of the splicing plate 10 corresponding to the transparent protective shell 6 near the rear edge.

[0023] See also Figure 4 In the figure, the elastic part includes an annular plate 18, which is fixedly mounted on the outer wall of the plug column 13, and one side wall of the annular plate 18 is in contact with one inner side surface of the cylinder 11, and a spring 19 is fixedly connected between the other side wall of the annular plate 18 and the other inner side surface of the cylinder 11, and the spring 19 is slidably mounted on the outer wall of the plug column 13.

[0024] See also Figure 2 and Figure 3 In the figure, the side wall of the splicing plate 10 corresponding to the rectangular plate 5 is fixedly connected with a block 14.

[0025] See also Figure 1 In the figure, transparent protective plates 8 are fixedly connected to the edges of both sides of the upper end of the operating table 2; specifically, the setting of the transparent protective plates 8 can protect the testing process from both sides of the operating table 2.

[0026] In this embodiment, when the stator of the motor to be tested is placed on the operating table 2, the handle 9 is then pulled to drive the transparent protective shell 6 to move at the front end of the operating table 2 (in this process, the transparent protective shell 6 will drive the rectangular plate 5 to move, and the rectangular plate 5 will drive the two sliders 15 to slide on the connecting rod 4). When the transparent protective shell 6 is located directly above the stator to be tested, the machine body 1 can be started to perform the testing operation. At this time, the transparent protective shell 6 can play a protective role.

[0027] When it is necessary to maintain the equipment on the operating table 2, you can first pull the pull plate 12 outward. The pull plate 12 will drive the plug 13 to slide between the splicing plate 10 and the inner wall of the cylinder 11, and the plug 13 will drive the annular plate 18 to slide in the cylinder 11 (in this process, the spring 19 between the cylinder 11 and the annular plate 18 will be squeezed on the outer wall of the plug 13), until the end of the plug 13 away from the pull plate 12 is flush with the side wall of the splicing plate 10. While keeping the pull plate 12 pulled, the transparent protective cover 7 is rotated upward. The transparent protective cover 7 will rotate upward on the rectangular plate 5 until the rear end of the transparent protective cover 7 is in contact with the front end of the block 14. Release the pull plate 12. Under the action of the spring 19, the plug 13 will automatically reset and be inserted into the socket 20 on the transparent protective shell 6. The transparent protective cover 7 can remain fixed after rotation, thereby avoiding obstruction when maintaining the equipment on the operating table 2 and easy to operate.

[0028] Example 2: Please refer to Figure 3 This embodiment further explains Example 1. The locking member in the figure includes a knob screw 17, which is tightened on the upper rear edge of the transparent protective shell 6, and the bottom end of the knob screw 17 is tightly fitted with the upper end of the transparent protective cover 7.

[0029] See also Figure 3 In the figure, the side wall of the transparent protective cover 7 located outside the transparent protective shell 6 is fixedly connected with a pull block 16.

[0030] In this embodiment, when testing two motor stators at the same time, the knob screw 17 can be turned upward first, and the knob screw 17 will rotate upward in the inner wall of the transparent protective shell 6, and the bottom end of the knob screw 17 will leave the upper end of the transparent protective cover 7. Then, the pull block 16 is pulled away from the transparent protective shell 6. The pull block 16 will drive the transparent protective cover 7 to slide outward in the transparent protective shell 6 until the transparent protective cover 7 moves to the required position. Then, the knob screw 17 is turned downward, and the transparent protective cover 7 can be re-fixed in the transparent protective shell 6 after moving. At this time, the transparent protective shell 6 and the transparent protective cover 7 can respectively play a protective role in the detection of the two motor stators.

[0031] It should be noted that the transparent protective shell 6 can be rotated upward and remain in a fixed state, thereby avoiding obstruction when maintaining the equipment on the operating table 2. When testing two motor stators at the same time, the transparent protective cover 7 inside the transparent protective shell 6 can move outward and remain in a fixed state, thereby playing a protective role in the detection of two motor stators at the same time.

[0032] It should also be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
