The replaceable working tool detects the tightness of the generator stator slot wedge based on the sound of the tapping operation. The tapping operation mechanism I of this device is relatively complex in structure. In actual use, if debris gets stuck between the armature fixing frame and the base, it will affect the tapping operation. Therefore, improvements have been made to this tapping operation mechanism. Utility Model Content

[0003] The purpose of the utility model is to provide a generator set slot wedge detection and knocking operation device and a detection system thereof, so as to solve the problem that the current knocking operation mechanism has a complex structure and is easily blocked during use, thus affecting the knocking operation.

[0004] To achieve the above-mentioned purpose, the utility model provides a generator set slot wedge detection and knocking operation device, including a slot-shaped support, a knocking frame, a motor and a cam. The knocking frame is installed on the slot-shaped support by pivoting, and a torsion spring is installed on the pivot. One end of the torsion spring acts on the knocking frame, and the other end acts on the slot-shaped support. The cam is installed in the slot-shaped support through a transmission shaft, and the motor is installed on one side of the slot-shaped support. The output shaft of the motor is connected to the transmission shaft. The rotation of the transmission shaft drives the cam to rotate, and the protrusion of the cam abuts against the knocking frame, thereby moving the knocking frame.

[0005] A hammer head is installed on the knocking frame at one end away from the groove-shaped support.

[0006] There are two torsion springs, which are respectively installed on both sides of the knocking frame.

[0007] A limit pin is also installed in the grooved support.

[0008] A convex block is provided at the bottom of the groove-shaped support, and a clamping groove is formed between the convex block and the groove-shaped support.

[0009] The bottom of the grooved support is also provided with a penetrating mounting hole.

[0010] A detection system is provided, which is equipped with the generator set slot wedge detection and knocking operation device.

[0011] Compared with the prior art, the present invention has the following technical effects:

When the cam rotates, the protruding part of the cam can abut against the knocking frame, thereby pressing the knocking frame downward, so that the knocking frame is tilted away from one end of the groove-shaped support. When the cam continues to rotate, the protruding part of the cam is staggered with the knocking frame, and the knocking frame swings under the action of the torsion spring, thereby knocking the slot wedge of the generator set. The overall structure is simpler and is not easy to get stuck when in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0026] Example 1:

[0027] See Figure 3-5 A generator set slot wedge detection and knocking operation device 10 includes a slot-shaped support 11, a knocking frame 12, a motor 13 and a cam 16. The knocking frame 12 is rotatably mounted on the slot-shaped support 11 via a pivot 14. A torsion spring 15 is mounted on the pivot 14. One end of the torsion spring 15 acts on the knocking frame 12, and the other end acts on the slot-shaped support 11. The cam 16 is mounted in the slot-shaped support 11 via a transmission shaft 17. The motor 13 is mounted on one side of the slot-shaped support 11. The output shaft of the motor 13 is connected to the transmission shaft 17. The rotation of the transmission shaft 17 drives the cam 16 to rotate. The protrusion of the cam 16 abuts against the knocking frame 12, thereby toggling the knocking frame 12. The rotation of the motor 13 drives the transmission shaft 17 to rotate. The cam 16 is fixedly connected to the transmission shaft 17, thereby driving the cam 16 to rotate. When the cam 16 rotates, the protrusion of the cam 16 can abut against the knocking frame 12. See Figure 4 , thereby pressing the knock frame 12 downward, causing the knock frame 12 to tilt away from one end of the grooved support 11. When the cam 16 continues to rotate, the protruding portion of the cam 16 is staggered with the knock frame 12, and the knock frame 12 swings under the action of the torsion spring 15, as shown in FIG. Figure 5 As shown, the slot wedge of the generator set is struck, the structure is simpler, and it is not easy to get stuck during use.

[0028] Furthermore, to improve the knocking effect, see Figure 4 A hammer head 18 is installed on the striking frame 12 at one end away from the grooved support 11.

[0029] See also Figure 3 In order to improve the knocking force of the knocking frame 12 under the torsion spring 15 effect, the torsion spring 15 is provided with two. Two torsion springs 15 are installed on the both sides of the knocking frame 12 respectively.

[0030] See also Figure 3 、 6 , a limit pin 19 is also installed in the groove support 11. By setting the limit pin 19, as shown in FIG. Figure 5 As shown, the lowest point of the leftward swing of the knock frame 12 is limited.

[0031] See also Figure 4 The bottom of the groove support 11 is provided with a convex block 111, and a slot 112 is formed between the convex block 111 and the groove support 11. By providing the convex block 111, the tool mounting bracket 20 is positioned and connected through the slots 112 formed on both sides. Figure 6 A slide groove cooperating with the convex block 111 is also provided on the working tool mounting frame 20.

[0032] Furthermore, the bottom of the grooved support 11 is also provided with a through mounting hole, which is convenient for fixing with the working tool mounting frame 20 by bolts. During implementation, the corresponding position of the working tool mounting frame 20 is provided with a long hole.

[0033] Example 2:

[0034] See also Figure 1 、 2 , a detection system is installed with the generator set slot wedge detection and knocking operation device 10.

[0035] Specifically in CN118641625A, the detection system includes a longitudinal telescopic mechanism 30, on which a working tool mounting frame 20 is mounted, and on which the generator set slot wedge detection and knocking operation device 10 is mounted.

[0036] Further, see Figure 6 Two of the aforementioned generator set slot wedge detection and knocking operation devices 10 are installed on the operation tool mounting frame 20, and a pickup 40 is installed between the two of the aforementioned generator set slot wedge detection and knocking operation devices 10.

[0037] Of course, the detection system can also be a generator set slot wedge detection and knocking operation device 10 installed on a walking robot.

[0038] The working principle of this utility model:

[0039] See also Figure 3 、 6 The motor 13 rotates, thereby driving the transmission shaft 17 to rotate, thereby driving the cam 16 to rotate. When the cam 16 rotates, the protrusion of the cam 16 can abut against the knock frame 12, see Figure 4 , thereby pressing the knock frame 12 downward, causing the knock frame 12 to tilt away from one end of the grooved support 11. When the cam 16 continues to rotate, the protruding portion of the cam 16 is staggered with the knock frame 12, and the knock frame 12 swings under the action of the torsion spring 15, as shown in FIG. Figure 4 As shown, the slot wedge of the generator set is struck.
