Each cantilever 13 and the connecting part are welded and fixed on the main shaft 11. The main shaft 11 is a round shaft, and a square shaft 12 is formed at one end of the main shaft 11; the cantilever 13 includes a pair of arm plates, a connecting shaft and a connecting block 14. The connecting block 14 is installed at one end of two arm plates through the connecting shaft, and the other ends of the two arm plates are welded to the shaft.

[0003] In the past, the inspection of cantilever welding accuracy and quality on the rotating shaft mainly relied on manual inspection. Traditional manual measuring tools such as height gauges and universal dividing plates, while ensuring dimensional accuracy, were difficult to meet the requirements of shortening construction time for large quantities; this also affected the measurement efficiency.

[0014] Furthermore, a guide groove is provided at the upper end of the detection block, and the guide screw passes from the first positioning block into the guide groove at the upper end of the detection block, and the guide screw limits the position of the detection block moving forward and backward in the sliding hole.

[0015] Furthermore, the clamping mechanism comprises

[0016] A support is fixedly arranged on the base, and the upper end of the support forms a main shaft supporting surface;

[0017] A bracket is fixedly arranged on the base;

[0018] A pressing plate, the rear end of which is hinged to the upper end of the bracket, and the front end of which is suitable for pressing the main shaft;

[0019] A spring has one end connected to the bracket and the other end connected to the pressure plate.

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0042] The present application provides a circuit breaker shaft detection fixture, which is described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0043] In order to solve the technical problem of low efficiency in detecting the welding accuracy of the cantilever 13 in the circuit breaker shaft in the prior art, an embodiment of the present application provides a circuit breaker shaft detection fixture, which is described in detail below.

[0044] like Figure 1 The circuit breaker shaft 1 shown includes a main shaft 11, three cantilevers 13 and three connecting parts. Each cantilever 13 includes a connecting block 14. One end of the main shaft 11 is a square shaft 12. The position of the connecting block 14 relative to the main shaft 11 represents the position of the cantilever 13 on the main shaft 11. The circuit breaker shaft detection fixture of the utility model mainly detects the position of the connecting block 14 to determine whether the installation position of the cantilever 13 on the main shaft 11 is qualified.

[0045] like Figures 2 to 7 As shown, a circuit breaker shaft detection fixture includes:

[0046] A base 6, on which two clamping mechanisms 3, three detection mechanisms 2 and a positioning mechanism 5 are arranged;

[0047] The main shaft 11 is horizontally placed on the clamping mechanism 3, and the clamping mechanism 3 clamps the main shaft 11 to limit the horizontal position of the rotating shaft 1;

[0048] The positioning mechanism 5 is suitable for controlling the circumferential position of the spindle 11;

[0049] The detection mechanism 2 is suitable for detecting the detection block 22 on the cantilever 13 to determine whether the welding position of the cantilever 13 on the spindle 11 is qualified.

[0050] To facilitate the handling of the clamp, handles are provided on both sides of the base 6.

[0051] Specifically, as an optional implementation in this embodiment, Figure 5 As shown, the detection mechanism 2 includes

[0052] A first positioning block 21, which is fixedly arranged on the base 6, and a sliding hole is provided on the first positioning block 21;

[0053] The detection block 22 has a detection opening formed at its front end. The detection block 22 moves back and forth in the sliding hole, and its detection opening is suitable for cooperating with the connecting block 14 on the cantilever 13 .

[0054] If the detection block 22 moves forward and its detection port can be plugged into the connection block 14, it means that the welding position of the cantilever 13 is qualified. If the detection block 22 cannot be inserted or is somewhat difficult to insert, it means that the cantilever 13 is unqualified.

[0055] Specifically, as an optional implementation in this embodiment, Figure 5As shown, a guide groove is provided at the upper end of the detection block 22, and the guide screw 23 penetrates into the guide groove at the upper end of the detection block 22 from the first positioning block 21, and the guide screw 23 limits the position of the detection block 22 moving forward and backward in the sliding hole.

[0056] The guide screw 23 and the guide groove can control the front and rear positions of the detection block 22 in the first positioning block 21 to prevent the detection block 22 from moving out of the first positioning block 21 .

[0057] Specifically, as an optional implementation in this embodiment, Figure 4 As shown, the clamping mechanism 3 comprises:

[0058] A support 31 is fixedly arranged on the base 6, and the upper end of the support 31 forms a support surface for the main shaft 11;

[0059] A bracket 32, which is fixedly arranged on the base 6;

[0060] The pressing plate 33 has a rear end hinged to the upper end of the bracket 32 ​​and a front end suitable for pressing the main shaft 11;

[0061] The spring 34 has one end connected to the bracket 32 ​​and the other end connected to the pressing plate 33 .

[0062] Principle of the clamping mechanism 3: The clamping force of the front end of the pressing plate 33 on the main shaft 11 depends on the tension of the spring 34. The front end of the pressing plate 33 is connected to a handle, and the pressing plate 33 can be driven to rotate by the handle.

[0063] In this embodiment, a pair of supporting bearings 41 are disposed at the upper end of the support 31 , and a pressing bearing 42 is disposed at the front end of the pressing plate 33 .

[0064] The support bearing 41 and the press-fit bearing 42 are both deep groove ball bearings.

[0065] The main shaft 11 is clamped between the three bearings, so that the circumferential angle of the main shaft 11 can be adjusted during the installation process.

[0066] Specifically, as an optional implementation in this embodiment, Figure 6 As shown, the positioning mechanism 5 includes

[0067] A second positioning block 51 is fixedly arranged on the base 6, and a positioning groove is provided at the upper end of the second positioning block 51; the square shaft 12 is suitable for extending into the positioning groove;

[0068] The oblique wedge block 52 is suitable for being inserted into the positioning groove and abutting against the side surface of the square shaft 12 in the positioning groove to limit the square shaft 12 from rotating in the positioning groove.

[0069] An inner bevel is formed in the positioning groove, and the bevel cooperates with the inclined wedge block 52 . The design of the inner bevel can expand the space between the square shaft 12 and the positioning groove, making it easier for the inclined wedge block 52 to be inserted.

[0070] Working process of the utility model circuit breaker shaft detection fixture:

[0071] like Figure 7 As shown, the rotating shaft 1 is placed on two clamping mechanisms 3, and the supporting bearing 41 on the support 31 presses the rotating shaft 1, and then the rotating shaft 1 is crimped by the crimping bearing 42, and then the rotating shaft 1 is rotated to make the cantilever 13 face the detection mechanism 2; then in the positioning mechanism 5, the inclined wedge block 52 is inserted into the positioning groove, and the inclined wedge block 52 abuts against the square shaft 12, which limits the rotation of the square shaft 12 and also limits the rotation of the rotating shaft 1, and the cantilever 13 can be detected at this time.

[0072] In the detection mechanism 2, the detection block 22 is moved forward. If the detection block 22 can fit in easily, it means that the cantilever 13 is qualified. If the detection block 22 cannot be inserted or is inserted with difficulty, it means that the cantilever 13 is unqualified.
