DETAILED DESCRIPTION

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] This utility model provides two technical solutions:

[0031] Figure 1-3 A first embodiment is shown: a rack plate surface flatness detection device, comprising:

[0032] The placing plate 1 is used to place the rack panel for detection. A dovetail chute 11 and a tooth groove 12 are opened on one side of the upper surface of the placing plate 1. The dovetail chute 11 and the tooth groove 12 are arranged side by side.

[0033] Leveling piece 2, the leveling piece 2 is arranged at the four corners of the lower surface of the placement plate 1, and is used to support and level the placement plate 1. The leveling piece 2 includes a stud 21 fixed at the four corners of the lower surface of the placement plate 1, and a screw sleeve 22 is sleeved on the outer side of the lower end of the stud 21. The bottom end of the screw sleeve 22 is movably connected to the base plate through a bearing. The screw sleeve 22 is driven up and down by twisting the stud 21 to adjust the height of one corner of the placement plate 1. By adjusting the height of the four studs 21, the placement plate 1 can be leveled, which improves the working detection accuracy of the device. A plurality of rubber heads 24 distributed at equal intervals are bonded to the lower surface of the base plate. The setting of the rubber head 24 increases the friction with the ground, so that the device will not move easily. At the same time, after the stud 21 is adjusted, the base plate will not be warped.

[0034] The movable plate 3 is arranged on one side of the upper surface of the placement plate 1, and a dovetail slider 31 is fixed on one side of the lower surface of the movable plate 3. The dovetail slider 31 is located in the dovetail groove 11. The dovetail slider 31 and the dovetail groove 11 cooperate to play a guiding role, so that the movable plate 3 maintains linear movement and prevents the movable plate 3 from separating from the placement plate 1. The four corners of the lower surface of the movable plate 3 are connected with balls 32 through ball grooves. The balls 32 fit with the upper surface of the placement plate 1. The setting of the balls 32 reduces the friction between the movable plate 3 and the placement plate 1, making the movable plate 3 easy to move.

[0035] Movable component 4, the movable component 4 is arranged on the movable plate 3, and is used for the horizontal and lifting movement of the device. The movable component 4 includes a first motor 41 fixed on the upper surface of the movable plate 3, and the output end of the first motor 41 is fixed with a gear 42, and the gear 42 is adapted to the tooth groove 12. The first motor 41 drives the gear 42 to rotate, and the gear 42 cooperates with the tooth groove 12 to drive the movable plate 3 to move. The movable component 4 also includes a support plate 43 fixed on the upper surface of the movable plate 3, and the upper end of the support plate 43 is inserted into the slot opened at the bottom end of the L-shaped plate 5. Telescopic cylinders 44 are fixed on both sides of the support plate 43, and the output end of the telescopic cylinder 44 is connected to the bottom end of the L-shaped plate 5. The telescopic cylinder 44 can drive the L-shaped plate 5 to move up and down. The setting of the support plate 43 plays a limiting role on the L-shaped plate 5, so that the L-shaped plate 5 keeps moving vertically up and down.

[0036] Figure 1 and 4 -5 shows a second embodiment, the main difference from the first embodiment is that it includes an L-shaped plate 5, the bottom end of the L-shaped plate 5 is connected to the movable component 4, a linear groove 51 is provided on the inner side of the upper end of the L-shaped plate 5, and limiting sliding grooves 52 are provided on both sides of the upper end of the L-shaped plate 5, and an adjustment component is provided on the L-shaped plate 5.

[0037] The adjusting component is used to detect the horizontal movement of the detection mechanism. The adjusting component includes a second motor 61 fixed to one end of the upper part of the L-shaped plate 5. The output end of the second motor 61 is connected to a screw rod 62, which is located inside the linear groove 51. The adjusting component also includes a connecting plate 63 arranged on the inner side of the upper part of the L-shaped plate 5. A protrusion 64 is fixed to the middle part of the upper surface of the connecting plate 63. The protrusion 64 is located in the linear groove 51, and the middle part of the protrusion 64 is connected to the screw rod 62 through a screw groove. The second motor 61 drives the screw rod 62 to rotate, and the screw rod 62 cooperates with the screw groove to drive the protrusion 64 to move in the linear groove 51, thereby driving the connecting plate 63 to move. Limit sliders are fixed at both ends of the upper surface of the connecting plate 63, and the limit slider is adapted to the limit slide 52. The limit slider and the limit slide 52 cooperate to guide the connecting plate 63, so that the connecting plate 63 maintains linear movement and supports the connecting plate 63.

[0038] The detection component 7 is used to detect the flatness of the rack plate surface. The detection component 7 is installed on the adjustment component. The detection component 7 includes a displacement sensor 71 installed in the middle of the lower surface of the connecting plate 63 and a telescopic plate 72 fixed at both ends of the lower surface of the connecting plate 63. The bottom of the movable end of the two telescopic plates 72 is fixedly connected by a mounting plate 73. A sensor receiving end 74 is installed in the middle of the upper surface of the mounting plate 73. The displacement sensor 71 and the sensor receiving end 74 cooperate to quickly and accurately detect the rack plate. The accuracy of the surface is measured, and the detection data is transmitted to the external controller at the same time. The lower surface of the mounting plate 73 is installed with a roller 75 through the mounting frame. The roller 75 contacts the frame plate surface to detect the flatness of the frame plate surface. An extension plate 76 is fixed to the inner side of the bottom of the fixed end of the telescopic plate 72. The extension plate 76 is connected to the mounting plate 73 by a compression spring 77. The setting of the compression spring 77 makes the roller 75 fit closely with the frame plate surface, so that the roller 75 can accurately detect the flatness of the frame plate surface.

[0039] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0040] When in use, first place the rack on the placement plate 1, and then adjust the height of the four corners of the placement plate 1 by screwing the four studs 21. The studs 21 cooperate with the screw sleeves 22 to level the placement plate 1, and then start the telescopic cylinder 44. The telescopic cylinder 44 drives the L-shaped plate 5 to move downward until the roller 75 contacts the plate surface of the rack, and then the reaction force generated by the compression spring 77 makes the roller 75 fit tightly on the rack plate surface, and then start the first motor 41. The first motor 41 drives the gear 42 to rotate, and the gear 42 cooperates with the tooth groove 12 to drive the movable plate 3 to move. The movable plate 3 drives the L-shaped plate 5 to move through the support plate 43, and then drives the roller 75 on the rack plate surface. When the roller 75 moves, the unevenness on the frame plate surface will cause the mounting plate 73 to fluctuate up and down. The sensor receiving end 74 on the mounting plate 73 cooperates with the displacement sensor 71 to accurately detect these fluctuations, thereby completing the flatness detection of the frame plate surface. When the detection of one line of the frame plate surface is completed, the L-shaped plate 5 is lifted by the telescopic cylinder 44 until the roller 75 is separated from the frame plate surface, and then the second motor 61 is started. The second motor 61 drives the screw rod 62 to rotate, and the screw rod 62 drives the connecting plate 63 to move through the protrusion 64, thereby driving the roller 75 to translate, and another part of the frame plate surface is detected, thereby improving the detection efficiency and accuracy of the device.
