Embodiment 1

[0033] A kind of guide rail stitching error measurement device of this embodiment, such as figure 1 As shown, it includes an air flotation pallet 1, a measuring device 2, and a pressing mechanism 3. The top of the air flotation pallet 1 and an adjacent side at the top are respectively provided with a measuring device 2; the measuring device 2 includes a lever 21. Coplanarity sensor 22, the fulcrum of the lever 21 is installed on the side wall of the air floatation plate 1, the cantilever end of the lever 21 is provided with a coplanarity sensor 22, and the other end of the lever 21 is provided with a pressing Mechanism 3; the measuring device 2 includes two levers 21 arranged in parallel.

[0034] The air flotation pallet 1 is U-shaped and is slidably installed on the outside of the guide rail. The air bearing gap with the guide rail surface is between 5 μm and 10 μm. Using the air bearing plate 1 as the bearing and moving part can ensure that the whole device is almost in a ...

Embodiment 2

[0041] This embodiment is further optimized on the basis of embodiment 1, such as figure 2 As shown, a positioning screw 02 is also included, and the lever 21 is provided with a positioning screw 02 on a side close to the coplanarity sensor 22 of the fulcrum.

[0042] After the adjustment of the initial position of the coplanarity sensor 22 is completed, that is, after the initial position of the lever 21 is fixed, the initial position of the lever 21 should be kept unchanged during the subsequent measurement process. However, during the sliding process of the air bearing plate 1 and the frequent lifting and falling of the lever 21, the initial position of the lever 21 may change, and it is necessary to re-adjust the initial position at this time. In order to avoid the occurrence of the above situation, the initial position of the lever 21 is effectively maintained, so a set screw 02 is installed through the lever 21, and the initial position of the lever 21 is adjusted by tu...

Embodiment 3

[0045] This embodiment is further optimized on the basis of above-mentioned embodiment 1 or 2, such as image 3 As shown, a measuring spring 01 is also included, and a measuring spring 01 is arranged between the lever 21 and the side wall of the air bearing plate 1 .

[0046] When measuring the flatness of the guide rail surface, the measuring end of the coplanarity sensor 22 should be in close contact with the guide rail surface, so a measuring spring 01 is arranged between the lever 21 and the guide rail surface, and when the lever 21 falls, the measuring spring 01 is in the In the slightly stretched state, the measuring spring 01 tightens the lever 21, so that the measuring end of the coplanarity sensor 22 is in close contact with the guide rail surface, and at the same time, the measurement repeatability of the coplanarity sensor 22 is ensured.

[0047] Other parts of this embodiment are the same as those of Embodiment 1 or 2 above, so details are not repeated here.

The guide rail splicing error measuring device comprises an air floating supporting plate, measuring devices and pressing mechanisms, wherein the measuring devices are arranged on the top of the air floating supporting plate and one adjacent side face on the top of the air floating supporting plate; each measuring device comprises levers and coplanarity sensors, the fulcrum of each lever is installed on the side wall of the air floating supporting plate, the cantilever end of each lever is provided with the coplanarity sensor, and the other end of each lever is provided with the pressing mechanism; and each measuring device comprises two levers which are arranged in parallel. The device has the beneficial effects that the device can continuously measure the coplanarity of multiple guide rails and the coplanarity of the top surfaces and the side surfaces of adjacent guide rails conveniently and efficiently with simpleoperation, and can monitor coplanarity error in real time.

Description

technical field [0001] The invention belongs to the technical field of guide rail splicing detection, and in particular relates to a guide rail splicing error detection device. Background technique [0002] At present, in most measurement and processing fields, there are more and more demands and applications for guide rails, especially for long guide rails with longer lengths. However, it is more difficult to ensure the overall straightness of the long guide rail and the levelness of the guide rail plane. At the same time, considering factors such as cost and storage, at present, for guide rails with a length greater than ten meters, several short guide rails are generally spliced ​​sequentially. . Due to the splicing errors of the short guide rails during splicing, coplanar errors occur at the splicing of the short guide rails, which in turn affects the straightness and plane levelness of the entire long guide rails. Therefore, accurately detecting and correcting the cop...
