[0016] like Figure 1-Figure 6 As shown, the utility model is a tool for assembling and adjusting two parallel long guide rails, comprising a guide rail base 1, a first tool 2 and a second tool 3.

The first side plate 8 and the second side plate 9 are vertically connected on both sides of the first bottom plate 7. The second side plate 9 is located below the first side plate 8. The second side plate 9 is wider than the first side plate 8. The first bottom plate 7 is provided with a plurality of first through holes 10 at intervals along its length direction. The second side plate 9 is provided with a plurality of threaded holes at intervals along its length direction. A first tightening screw 12 is respectively provided in any threaded hole. A first fixed slider 13 is fixedly provided at both ends of the first bottom plate 7.

[0018] The second tooling 3 includes a second bottom plate 14, a second fixed slider 15 is fixedly arranged on the lower side of the second bottom plate 14, a fixed seat 16 is arranged on the upper side of the second bottom plate 14, a second through hole 17 penetrating from top to bottom is arranged in the fixed seat 16, a vertical screw 18 is passed through the second through hole 17, the diameter of the second through hole 17 is larger than the diameter of the screw 18, an opening 19 is arranged in the side wall of the fixed seat 16, the opening 19 penetrates the fixed seat 16 along the thickness direction of the second bottom plate 14, a nut 20 is arranged on the screw 18 in the opening 19, and the vertical width of the opening 19 is larger than the vertical thickness of the nut 20. A floating block 21 is connected to the lower end of the screw rod 18, and a floating slider 22 is fixedly arranged on the floating block 21. A tightening screw mounting seat 23 is respectively arranged on both sides of the floating slider 22 on the second bottom plate 14. A second tightening screw 24 is respectively passed through the two tightening screw mounting seats 23. The tail ends of the two second tightening screws 24 are respectively in contact with the end surfaces of both ends of the floating slider 22. A micrometer mounting seat is arranged on the second bottom plate 14 above the floating slider 22. A micrometer 25 is installed in the micrometer mounting seat. The measuring end of the micrometer 25 is in contact with the upper surface of the floating slider 22.

[0019] Furthermore, the number of the second fixed sliding blocks 15 is two, which are spaced apart along the length direction of the lower guide rail step mounting plate 5 .

[0020] Specifically, the upper guide rail plane mounting plate 4, the lower guide rail step mounting plate 5, the tightening screws, the micrometer, etc. in this embodiment all adopt the well-known solutions in the prior art, which are well understood by those skilled in the art and will not be described in detail here.

[0021] The working principle of this utility model:

[0022] The lower rail (not shown) is installed in a stepped manner, and the upper rail (not shown) is installed in a plane. The length of the upper rail plane mounting plate 4 is greater than or equal to the length of the upper rail, and the length of the lower rail step mounting plate 5 is greater than or equal to the length of the lower rail.

[0023] During the machining process, the flatness of the plane of the upper guide rail plane mounting plate 4 and the step horizontal surface 27 of the lower guide rail step mounting plate 5, as well as the verticality and straightness of the step horizontal surface 27 and the step vertical surface 28 are ensured, and the table is measured on the machine tool. The flatness processing deviation of the step surface is 0.025mm / 1m, and the total length deviation is 0.05mm / 4m.

[0024] The diameter of the second through hole 17 is larger than the diameter of the screw rod 18, so that the screw rod 18 can move up and down, and the width of the opening 19 is larger than the thickness of the nut 20, so that the nut 20 can move up and down in the opening 19, so that the floating slider 22 can float up and down. The second tightening screw 24 does not completely tighten the floating slider 22, but limits the floating slider 22 to the left and right while allowing it to float up and down.

[0025] Guide rail installation process:

[0026] like Figure 5 As shown, the lower rail is installed on the lower rail step mounting plate 5, and the lower rail screws 29 are tightened one by one to fix the lower rail. The first tooling 2 is installed, the first fixed slider 13 is installed on the lower rail, the first side plate 8 presses the lower rail, so that the side of the lower rail is close to the vertical surface 28 of the step, and the screwdriver is passed through the first through hole 10 to loosen all the lower rail screws 29 covered by the C-type mounting seat 6 by half a turn, and then the first tightening screws 12 are tightened one by one from right to left. The first tightening screws 12 tighten the bottom surface of the lower rail step mounting plate 5, so that the bottom surface of the rail is completely close to the horizontal surface 27 of the step, and then the lower rail screws 29 are tightened again; then, the first tooling 2 is slid to the left, and the above steps are repeated, and finally the entire lower rail is completely close to the step; then the lower rail screws 29 are removed at intervals (first disassemble the odd number and then the even number), apply thread glue, and then tighten with a torque wrench.

[0027] like Figure 6As shown, the upper rail is installed on the upper rail plane mounting plate 4, and a spacing limiting fixture is used to determine the spacing between the upper rail and the lower rail. The spacing limiting fixture is composed of a vertical rod, and the upper and lower end surfaces of the vertical rod are respectively in close contact with the lower side surface of the upper rail and the upper side surface of the lower rail, so as to quickly and roughly determine the installation position of the upper rail, reduce the workload of adjustment, and tighten the upper rail screws 30 one by one. Install the second fixture 3, and the second fixed slider 15 is installed on the lower rail. Return the micrometer 25 to zero, loosen several upper rail screws 30, and then move the second tool 3 within the range of the loosened upper rail screws 30. If the micrometer 25 jumps, use a rubber hammer to tap the upper rail to make the micrometer 25 jump within 0.0025mm. The second tool 3 continues to move within the range and continuously adjusts the reading of the micrometer 25 until the readings of the micrometer 25 within the range are all within 0.0025mm. Then tighten the upper rail screws 30, and adjust all the upper rail screws 30 in this way so that the parallelism between the upper rail and the lower rail meets the requirement of being high enough. After adjusting the upper rail, remove all the upper rail screws 30 one by one, apply thread glue, and then tighten them with a torque wrench.

[0028] If the guide rail's own accuracy requirement needs to reach P level or higher, a laser interferometer can be used to assist in adjusting the installation accuracy of the guide rail.

[0029] By using the first tooling and the second tooling of the utility model to install the parallel long guide rails, a very high parallelism assembly requirement between the upper guide rail and the lower guide rail can be met, and the installation accuracy of the two parallel long guide rails can be greatly improved.
