[0016] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2 As shown, the automobile battery box cover inspection fixture provided in the embodiment of the present application includes a base 1, a moving assembly 2 for supporting the base 1, a flatness detection mechanism 3 provided on the base 1, a position detection mechanism 4, and a plurality of clamping mechanisms 5. The position detection mechanism 4 includes a supporting seat 41 fixedly provided on the base 1 and a plurality of positioning pins 42 provided on the supporting seat 41. The clamping mechanism 5 is used to fix the box cover on the supporting seat 41. The flatness detection mechanism 3 includes a guide rail 31 fixedly provided on the base 1 along the X direction, a crossbeam 32 slidably provided on the guide rail 31, a plurality of dial indicators 33 arranged on the crossbeam 32 along the Y direction, a locking strip 34 fixedly provided on the base 1 along the X direction, and a locking member 35 provided on the crossbeam 32. The locking strip 34 is provided with a plurality of locking holes 301 equidistantly provided along the X direction for cooperating with the locking member 35.

[0018] During actual use, the box cover is placed on the support seat 41 after being passed through the positioning pin 42. If the box cover successfully passes through the positioning pin 42, it indicates that the position of the box cover is qualified. If the box cover fails to pass through the positioning pin 42, it indicates that the position of the box cover is unqualified. After the box cover passes through the positioning pin 42 and is supported by the support seat 41, the box cover is fixed to the support seat 41 by the clamping mechanism 5. Then, the crossbeam 32 is moved along the guide rail 31 so that the sensing end of the dial indicator 33 contacts the upper end surface of the box cover and moves along the X direction. Each movement distance is the distance between the two locking holes 301. After one movement, the locking bar 34 is locked to the crossbeam 32 by the locking member 35. When the entire inspection fixture needs to be moved, the flatness detection mechanism 3, the clamping mechanism 5 and the position detection mechanism 4 are driven to move by the moving component 2.

[0019] In the above design, the design of the moving component 2 facilitates the movement of the entire inspection fixture, the flatness detection mechanism 3 facilitates the flatness detection of the box cover and ensures the detection accuracy, and the position detection mechanism 4 facilitates the position detection of the box cover, so that the box cover can be simultaneously detected for position and flatness, effectively improving efficiency and detection accuracy.

[0020] Specifically: Figure 1 and Figure 3 As shown, several of the clamping mechanisms 5 are circumferentially arranged on the outside of the supporting seat 41, and the clamping mechanism 5 includes a fixed block 51 fixed on the base 1, a quick clamp 52 arranged on the fixed block 51, and a clamping block 53 arranged on the quick clamp 52. Each of the clamping mechanisms 5 corresponds to a positioning pin 42, and the clamping block 53 is provided with a avoidance hole 501 for avoiding the positioning pin 42.

[0021] In actual use, after the box cover passes through the positioning pin 42 and is placed on the supporting seat 41, the clamping block 53 is driven by the quick clamp 52 to press the box cover from the upper end surface of the box cover.

[0022] In the above design, the clamping mechanism 5 uses a quick clamp 52 to drive the clamping block 53 to clamp, which can ensure the rapid clamping 52 and rapid release of the box cover.

[0023] Specifically: Figure 1 and Figure 2 As shown, the number of the guide rails 31 and the locking heads is at least two, and guide rails 31 and locking strips 34 are provided on both sides of the supporting seat 41. Both ends of the crossbeam 32 are slidably connected to the guide rails 31 and are fixedly connected to the locking strips 34 through locking members 35. The crossbeam 32 includes a cross column 321, end seats 322 at both ends of the cross column 321, and a connecting plate 323 arranged on the cross column 321 along the Y direction. A dial indicator 33 is provided on each of the connecting plates 323. The end seats 322 are slidably connected to the guide rails 31 and are locked to the locking strips 34 through locking members 35.

[0024] During actual use, the dial indicator 33 is fixed by the connecting plate 323 , and is slidably connected to the guide rail 31 through the end seat 322 and then locked with the locking strip 34 .

[0025] In the above design, guide rails 31 and locking strips 34 are provided on both sides of the supporting seat 41, which can ensure synchronous and stable supporting of both ends of the beam 32, thereby ensuring more accurate detection of the flatness of the box cover end surface.

[0026] Specifically: Figure 1 As shown, the moving assembly 2 includes a metal frame 21 for supporting the base 1 , a universal wheel 22 provided at the lower end of the metal frame 21 , and a handle 23 provided at one side of the metal frame 21 .

[0027] During actual use, the metal frame 21 is driven to move via the universal wheels 22 by pulling the handle 23 .

[0028] In the above design, the structural design of the moving component 2 facilitates the rapid movement of the entire inspection fixture.

[0029] Specifically, the locking strip 34 is a metal strip, the locking hole 301 is a screw hole, and the locking member 35 is provided with an external thread that matches the screw hole.

[0030] In actual use, when the crossbeam 32 and the locking strip 34 need to be locked, the external thread of the locking member 35 is threadedly connected to the screw hole of the locking hole 301 .

[0031] In the above design, the structural design of the locking strip 34 and the locking member 35 facilitates rapid locking.

[0032] To further explain in detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
