The clamping assembly includes a first clamping frame, and a second clamping frame is connected to one side of the first clamping frame. Drawing boards are arranged on the inner sides of the second clamping frame and the first clamping frame. Connecting seats are connected to the lower sides of both outer walls of the first clamping frame. Reserved holes are opened in the inner sides of the connecting seats. A movable frame is connected to the inner side of the fixed seat, and a first fixing column is movably connected to the end of the movable frame. A fixed frame is connected to the inner bottom end of the fixed seat, and a second fixing column is movably connected to the top of the fixed frame. Connecting pens are installed on the outer walls of the second fixing column and the first fixing column.

[0007] Preferably, the first clamping frame and the bearing seat form a detachable structure through the connecting seat and bolts.

[0008] Preferably, the movable frame is connected to the fixed seat through a spring, and a slider is connected to the outer wall of the end of the movable frame extending into the fixed seat. A reserved groove is opened in the inner side of the fixed seat.

[0009] Preferably, the first fixing column forms a movable structure with the fixing base through a movable frame, and three groups of first fixing columns are distributed.

[0010] Preferably, the drawing board and the connecting pen are vertically distributed, and the connecting pen is threadedly connected to both the first fixing column and the second fixing column.

[0011] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, through the settings of the fixing base, the motor body and the output shaft, etc., people insert the output shaft into the middle of multiple groups of distributed fixing columns, start the motor body, and make it drive the output shaft to rotate. When there is no crosstalk phenomenon of the output shaft, the connecting pen will remain stationary. If there is a crosstalk phenomenon and the connecting pen draws a short horizontal line, it indicates that there is an abnormality in the output shaft itself. If the connecting pen inserts into the drawing board and the shaking of the drawing board is very obvious, it indicates that the connection between the output shaft and the end cover of the motor body is loose, thereby facilitating people to assist in judging the specific problems of the output shaft and effectively improving the practicability of the device.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Referring to Figures 1-4 , a detection device for the axial movement of the output shaft of a motor, including a bearing seat 5. One side of the top of the bearing seat 5 is connected with a fixed seat 3, and a clamping assembly 6 is arranged on one side of the fixed seat 3. The clamping assembly 6 includes a first clamping frame 601, and a second clamping frame 602 is connected to one side of the first clamping frame 601. Drawing boards 11 are arranged on the inner sides of the second clamping frame 602 and the first clamping frame 601. Both sides below the outer wall of the first clamping frame 601 are connected with connecting seats 15. The drawing board 11 and the connecting pen 4 are vertically distributed, and the connecting pen 4 is threadedly connected to both the first fixing column 7 and the second fixing column 9. The image drawn by the connecting pen 4 on the drawing board 11 can assist people in judging the specific problems of the axial movement of the output shaft 2. A reserved hole 16 is opened in the inner side of the connecting seat 15. The first clamping frame 601 and the bearing seat 5 form a detachable structure through the connecting seat 15 and bolts. The connecting seat 15 and the bearing seat 5 are connected through bolts, so that the drawing board 11 clamped by the first clamping frame 601 and the second clamping frame 602 is in a proper position and is not easy to move. An activity frame 8 is connected to the inner side of the fixed seat 3, and the end of the activity frame 8 is movably connected with a first fixing column 7. The bottom end of the inner side of the fixed seat 3 is connected with a fixed frame 10, and the top end of the fixed frame 10 is movably connected with a second fixing column 9. Connecting pens 4 are installed on the outer walls of both the second fixing column 9 and the first fixing column 7; the activity frame 8 is connected to the fixed seat 3 through a spring 13, and a slider 14 is connected to the outer wall of the end of the activity frame 8 extending into the fixed seat 3. A reserved groove 12 is opened in the inner side of the fixed seat 3. The first fixing column 7 and the fixed seat 3 form a movable structure through the activity frame 8, and three groups of the first fixing columns 7 are distributed. When the output shaft 2 sways left and right, it can push the first fixing column 7 to move, and then the end of the activity frame 8 connected to the first fixing column 7 can extend into the reserved groove 12, and under the reset action of the spring 13, it performs a reset operation. Working principle: When in use, first, the staff places the motor body 1 whose output shaft 2 needs to be detected on the bearing seat 5, and inserts the output shaft 2 into the middle of multiple groups of arranged fixing columns. Subsequently, the motor body 1 is started, so that the output shaft 2 rotates. When there is no axial movement of the output shaft 2, the connecting pen 4 will remain stationary. If there is an axial movement phenomenon, and the connecting pen 4 draws short horizontal lines on the pre-set drawing board 11, it indicates that the output shaft 2

[0024] If an abnormality occurs in itself, and when the connecting pen 4 is inserted into the drawing board 11, making the shaking of the drawing board 11 very obvious, it indicates that the connection between the output shaft 2 and the end cover of the motor body 1 is loose, thus facilitating people to assist in judging the specific problem of the output shaft 2.
