[0045] a mounting frame 1;

[0046] a horizontal push-pull assembly 2 installed on the mounting frame 1;

[0047] a first wedge body 3 connected with the horizontal push-pull assembly 2, the horizontal push-pull assembly 2 being used for driving the first wedge body 3 to slide horizontally on the mounting frame 1, and the top surface of the first wedge body 3 being inclined downward along one of the sliding directions of the first wedge body 3;

[0061] Preferably, the rail profile precision adjustment device further comprises:

[0062] a driving mechanism 5 connected to the worm 221 and configured to drive the worm 221 to rotate.

[0063] Specifically, in other embodiments as shown in Figure 6 the worm 221 can be rotated manually or by other adjustment members other than the components included in the rail profile precision adjustment device, in this embodiment, the worm 221 is rotated by the driving mechanism 5, and the driving mechanism 5 can be a motor or other mechanism capable of driving the worm 221 to rotate.

[0064] AsFigure 7 As shown, in some preferred embodiments, the motion conversion assembly 21 comprises:

[0065] a gear 211 horizontally mounted on the mounting frame 1 and coaxially connected with the worm wheel 222;

[0066] a rack 212 horizontally arranged and engaged with the gear 211, and one end of which is fixedly connected with the first wedge 3.

[0067] Specifically, when the worm wheel 222 rotates, the gear 211 coaxially connected therewith rotates and drives the rack 212 engaged therewith to produce horizontal displacement, thereby driving the first wedge 3 to slide horizontally on the mounting frame 1.

[0068] In this embodiment, the rail profile precision adjustment device of the present application is provided with the gear 211 and the rack 212, which can produce horizontal displacement of the rack 212 based on rotation of the gear 211, thereby enabling the motion conversion assembly 21 to drive the first wedge 3 to slide horizontally on the mounting frame 1.

[0070] In this embodiment, the rail profile precision adjustment device of the present application is provided with the first limiting portion 11, which can limit the slidable range of the first wedge 3 on the mounting frame 1, thereby preventing the first wedge 3 from sliding excessively and causing the second wedge 4 to slide off the first wedge 3.

[0071] As shown, in some preferred embodiments, the second wedge 4 is provided with a sliding portion 41 on the side close to the first limiting portion 11; Figure 2

[0072] The first limiting portion 11 is provided with a sliding groove 111 arranged vertically;

[0075] In some preferred embodiments, the sliding groove 111 is a dovetail groove.

[0076] ​Specifically, since the slot width of the dovetail groove is smaller than the groove bottom width, the second wedge body 4 can only slide up and down on the mounting frame 1 and cannot slide horizontally, so in this embodiment, the rail profile accuracy adjusting device of the application is provided with a dovetail groove, which can lock the sliding direction of the second wedge body 4, thereby better preventing deviation during profile accuracy adjustment.

[0077] In some preferred embodiments, the mounting frame 1 is provided with a second limiting portion 12 arranged on one side of the first wedge body 3 and opposite to the first limiting portion 11.

[0078] In this embodiment, the rail profile accuracy adjusting device of the application can limit the slidable range of the first wedge body 3 on the mounting frame 1 from two sliding directions of the first wedge body 3, thereby ensuring that the second wedge body 4 will not slide off the first wedge body 3 due to excessive sliding of the first wedge body 3.

[0079] As shown in Figure 3 In some preferred embodiments, the first wedge body 3 is provided with a vertically arranged mounting groove 31.

[0080] The second wedge body 4 and the mounting frame 1 are respectively provided with a vertically arranged first mounting hole 42 and a second mounting hole 13, and the first mounting hole 42, the second mounting hole 13 and the mounting groove 31 are arranged opposite to each other.

[0081] In this embodiment, the rail profile accuracy adjusting device of the application is provided with the first mounting hole 42, the second mounting hole 13 and the mounting groove 31, which can be fixedly installed at the bottom of the display equipment production line rail 10 based on a screw pin or other connecting member based on the second mounting hole 13, and the first wedge body 3 and the second wedge body 4 are installed between the mounting frame 1 and the display equipment production line rail 10, and the first wedge body 3 of the application is provided with the mounting groove 31, which facilitates the horizontal sliding of the first wedge body 3 on the mounting frame 1, so the rail profile accuracy adjusting device 20 of the application can be installed at the bottom of the display equipment production line rail 10 to adjust the profile accuracy of the rail.

[0082] In a second aspect, as shown in Figure 4 and Figure 5 The application provides a display equipment production line rail, which is provided with a plurality of rail profile accuracy adjusting devices 20 as any one of the above on both sides of the bottom.

[0083] Specifically, the rail profile accuracy adjusting device 20 can adjust the profile accuracy of the local area of the display equipment production line rail 10 where it is located, so the plurality of rail profile accuracy adjusting devices 20 arranged on both sides of the bottom of the display equipment production line rail 10 can cooperate to adjust the profile accuracy of the entire rail.
