[0029] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0030] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show the components related to the present application rather than being drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0031] The following is combined with Figure 1-4 The specific implementation methods of this application are further described.

[0032] Example:

[0033] The present application embodiment discloses a precision cam lever detection mechanism, combined with Figure 1 and Figure 2 It is understood that the workbench 2 includes a circular workbench 2, which is rotatably connected to the work frame 1. The work frame 1 is used to support the workbench 2, and the workbench 2 and the work frame 1 can be rotatably assembled by plane bearings, or other bearings. The workbench 2 is hollow, so that the detection roller 15 can be placed in the middle. The detection roller 15 can also be suspended, or on other mechanical arms or other mechanical equipment. When detection is required, the detection roller 15 must be placed directly above the cam member 4.

[0034] Combination Figure 3 and Figure 4 It can be seen that the workbench 2 is provided with an annular table 3, and the annular table 3 is provided with a channel 31 communicating with each other from top to bottom, and a cam member 4 is slidably embedded in the channel 31, and the cam surface of the cam member 4 faces upward, and the bottom of the cam member 4 is a horizontal surface 41, and a guide rod 5 is fixed on the horizontal surface 41, and a guide hole 21 for the guide rod 5 to pass through is provided on the workbench 2, and a through hole 42 is provided on the cam member 4, and an insertion rod 6 is inserted into the through hole 42. The upper surface of the cam member 4 is the cam surface.

[0035] The workbench 2 is provided with a support 8, on which a lever 7 is rotatably connected, and one end of the lever 7 supports one end of the insertion rod 6. The support 8 and the workbench 2 are slidably connected, and the lever 7 approaches or moves away from the insertion rod 6 by sliding.

[0036] During the specific operation, the workbench 2 can be rotated. The annular table 3 is an open-loop structure. The annular table 3 is rotated to make the annular notch face the bottom of the detection roller 15. At this time, the channel 31 avoids the detection roller 15, and then the cam member 4 is placed in, which is very easy. Thus, the assembly efficiency is improved.

[0037] A U-shaped groove 32 is provided on the annular platform 3, and the insertion rod 6 moves in the groove 32. The design of the groove 32 can further limit the insertion rod 6, so that the insertion rod 6 can contact the limit when it is lifted. By operating the lever member 7 and swinging the lever member 7, the cam member 4 can be raised and lowered. The cam member 4 maintains contact with the lever member 7 due to its own gravity.

[0038] In order to improve the reliability of the lifting and lowering of the cam member 4, two guide rods 5 are provided, which are respectively located on both sides of the cam member 4. The bottom of the cam member 4 is a horizontal plane 41 on which abutment columns 9 are threadedly connected. A spring 10 is also sleeved on the guide rod 5. One end of the spring 10 abuts against the bottom of the cam member 4, and the other end of the spring 10 abuts against the workbench 2. In this way, the spring 10 also provides elastic support to overcome the gravity of the cam member 4. By adjusting the fixed length position of the abutment columns 9, the movable height of the abutment columns 9 and the workbench 2 can be controlled.

[0039] In addition, the lever includes an arc surface end 71, a horizontal section 72 and an extension section 73. The arc surface end 71 is perpendicular to one end of the horizontal section 72, and the extension section 73 is perpendicular to the other end of the horizontal section 72. A shaft hole is provided at a right angle between the horizontal section 72 and the extension section 73, and the shaft hole is rotatably transferred to the support 8 through the insertion shaft 11. The design of the arc surface end 71 avoids causing wear on the insertion rod 6. With this structure, the movement of the lever can be associated with the up and down movement of the cam member 4.

[0040] In order to facilitate assembly, the support 8 is fixed on the slider 12, and the slider 12 is slidably connected to the slide rail 13 and embedded in the slide groove 22 of the workbench 2. In this way, the support 8 can be kept away from the plunger 6 first, and the support 8 can be brought close after the cam member 4 is installed, which is convenient for assembly operation.

[0041] Finally, a level ruler 14 may be provided on the horizontal section 72 at the end of the extension section 73. The level ruler 14 is a miniature bubble level ruler 14 (instrument), which can be used to determine whether the horizontal state is present.

[0042] The above embodiments are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be included in the protection scope of the present application.
