Description

Technical Field

[0001] This utility model relates to a device for installing parallel guide rails, belonging to the field of parallel guide rail installation technology. Background Technology

[0002] Linear guides are widely used in applications requiring high precision or high-speed linear reciprocating motion and can withstand a certain amount of torque, such as in industrial printers, laser cutting machines, and machine tools. Figure 1 As shown, the linear guide has a parallel base rail 1 and a secondary rail 2, which are respectively mounted on the base rail base plate 3 and the secondary rail base plate 4. The center distance between the base rail 1 and the secondary rail 2 is L. The base rail 1 is mounted on the stepped base rail base plate 3, with the reference surface of the base rail 1 pressed against the stepped surface of the base rail base plate 3.

[0003] Because the baseline rail 1 and the secondary rail 2 are long and parallel, high requirements are placed on the straightness and parallelism during the assembly of the linear guide rails.

[0004] In existing technology, during the installation of guide rails, one of the two guide rails is first fixed, and a bolt is inserted into the other guide rail but not tightened. Then, an adjusting tool is connected to the sliders on both guide rails. The adjusting tool and sliders are then moved along the guide rails to adjust them to parallelism. Finally, the bolts are tightened to fix the guide rails in place, completing the installation. However, existing adjusting tools cannot adjust the fixed position of the sliders; therefore, they are only suitable for guide rails with specific spacing and a single model, and cannot be used to adjust the parallelism and straightness of guide rails with multiple spacings and models.

[0005] Another existing installation method involves fixing one of the two guide rails, measuring the distance between the two rails using a dial indicator mounted on a magnetic bracket, adjusting the two rails to be parallel, and then fixing the other rail. This installation method requires a high level of skill from the operator and has low installation efficiency. Utility Model Content

[0006] This invention addresses the shortcomings of existing linear guide rail installation technology by providing a tooling for quick installation of adjustable center distance parallel guide rails that is easy to operate and has high installation accuracy.

[0007] The tooling for quick installation of adjustable center distance parallel guide rails of this utility model adopts the following technical solution.

[0008] The tooling includes a baseline rail installation tooling and a secondary rail rail installation tooling. The baseline rail rail installation tooling is used to install the baseline rails separately. After the baseline rails are installed, the secondary rail rails are then installed using the secondary rail rail installation tooling.

[0009] The reference rail installation fixture includes a first support base. An upper positioning support wheel and an auxiliary support wheel are installed on the upper end face of the first support base. The auxiliary support wheel is installed on the first support base by a mounting screw. A side positioning support wheel is installed on one side of the first support base, and a locking support wheel is installed on the other side by an adjusting screw.

[0010] Locking nuts are provided on the mounting screw and adjusting screw. An adjusting block is connected to the lower end of the adjusting screw, and a mounting shaft is provided on the adjusting block. The locking support wheel is mounted on the mounting shaft. A spring is provided between the mounting shaft and the adjusting block. A positioning block with crosshairs is provided on the first support base.

[0011] In the aforementioned reference rail installation fixture, the positioning support wheel rests against the top surface of the reference rail, the auxiliary support wheel rests against the bottom surface of the reference rail base plate, and the height of the auxiliary support wheel is adjusted to make the upper surface of the first support level. The side positioning support wheel rests against the reference surface of the reference rail, and the locking support wheel rests against the side of the reference rail base plate. The locking support wheel is flush with the side of the reference rail base plate by adjusting the screw. After tightening the first connecting bolt of the reference rail to the rail base plate, the reference rail installation fixture is moved to ensure that the reference surface of the reference rail always coincides with the reference surface of the rail base plate, thus guaranteeing the installation accuracy of the reference rail.

[0012] The auxiliary guide rail installation fixture includes a second support base, a third support base, and an adjusting screw. Both the second and third support bases are equipped with an upper positioning support wheel, a side positioning support wheel, and a locking support wheel. The upper positioning support wheel is located on the upper surface of the second or third support base, the side positioning support wheel is located on one side of the second or third support base, and the locking support wheel is located on the other side of the second or third support base via an adjusting screw. An adjusting screw connects the second and third support bases and is connected to a nut on the third support base. A locking nut is provided on the adjusting screw; after the distance between the baseline guide rail and the auxiliary guide rail is adjusted, the adjusting screw is fixed by the locking nut. A guide rod is provided between the second and third support bases and is mounted on the third support base. The second support base has a guide hole into which the guide rod extends and moves, providing guidance when the adjusting screw moves the third support base. A positioning block with a crosshair is placed on the third support base.

[0013] In the aforementioned auxiliary guide rail installation fixture, the upper positioning support wheel rests against the top surface of the reference guide rail or auxiliary guide rail, while the side positioning support wheel and the locking support wheel rest against the two sides of the reference guide rail 1 or auxiliary guide rail, clamping it onto the reference guide rail or auxiliary guide rail. The adjusting screw rotates and moves to adjust the distance between the second and third support seats, which is the distance between the reference guide rail and the auxiliary guide rail. This fixes the center distance between the reference guide rail and the auxiliary guide rail to a fixed value, thus ensuring the straightness and flatness of the auxiliary guide rail.

[0014] This invention is easy to operate and has high installation accuracy. It solves the technical problem that the installation of parallel long guide rails in the prior art cannot meet the requirements of parallelism and straightness. It can be applied to different models of linear guide rails, has a wide range of applications, can shorten the adjustment time, and improve work efficiency. Attached Figure Description

[0023] The tooling for quick installation of adjustable center distance parallel guide rails of this utility model, such as... Figure 2 As shown, it includes a baseline rail installation fixture and a secondary rail installation fixture. The baseline rail installation fixture is used to install baseline rail 1 alone. After baseline rail 1 is installed, secondary rail 2 is installed using the secondary rail installation fixture.

[0024] like Figure 2 and Figure 3 As shown, the reference rail mounting fixture includes a first support base 5, upper positioning support wheels 6, side positioning support wheels 7, auxiliary support wheels 14, adjusting screws 9, locking support wheels 10, and adjusting blocks 11. Two upper positioning support wheels 6 and two auxiliary support wheels 14 are mounted on the top surface of the first support base 5. The auxiliary support wheels 14 are mounted on the first support base 5 via mounting screws 8, which are located in elongated holes in the first support base 5 and have locking nuts. The positioning support wheels 6 rest against the top surface of the reference rail 1, and the auxiliary support wheels 14 rest against the bottom surface of the reference rail base plate 3. The upper surface of the first support base 5 is leveled by adjusting the mounting screws 8 and then fixed in place by the locking nuts. The side positioning support wheels 7 are mounted on one side of the first support base 5 and rest against the reference surfaces of the reference rail 1. The locking support wheels 10 are mounted on the other side of the first support base 5 via adjusting screws 9 and rest against the side of the reference rail base plate 3. Locking nuts are provided on the adjusting screws 9. A vertical adjusting screw 9 is provided on the outer side of the auxiliary support wheel 14 on the first support base 5. The lower end of the adjusting screw 9 is connected to an adjusting block 11. A fixed support wheel 10 is mounted on the adjusting block 11 via a mounting shaft 13. A spring 12 is provided between the mounting shaft 13 and the adjusting block 11. Multiple fixed support wheels 10 can be provided; five are shown in the figure.

[0025] The usage process of the above-mentioned baseline rail installation fixture is as follows.

[0026] The side positioning support wheel 7 is pressed against the side of the reference rail 1, and the upper positioning support wheel 6 is pressed against the top surface of the reference rail 1. The height of the auxiliary support wheel 14 is adjusted by the mounting screw 8 to ensure that the upper surface of the first support seat 5 is horizontal, and the auxiliary support wheel 14 is fixed by the locking nut on the mounting screw 8. Then, the height of the adjusting block 11 is adjusted by the adjusting screw 9 so that the locking support wheel 10 is flush with the side of the reference rail base plate 3. The two outermost locking support wheels 10 are adjusted with nuts to clamp them with the side of the reference rail base plate 3, and the three middle ones are secured by the preload of the spring 12 to ensure that the reference surface of the reference rail 1 is in close contact with the stepped surface of the reference rail base plate 3. The first connecting bolt between the reference rail 1 and the reference rail base plate 3 is tightened, and the reference rail installation fixture (first support seat 5) is moved to ensure that the reference surface of the reference rail 1 always coincides with the reference surface of the reference rail base plate 3, thus ensuring the installation accuracy of the reference rail 1. Finally, secure the baseline rail 1 to the baseline rail base plate 3.

[0027] To improve the installation accuracy of the linear guide and reduce the time required for re-inspection, a laser level 26 can be placed on the base plate 3 of the baseline guide, and a positioning block 27 can be placed on the upper surface of the first support 5. (See [reference]) Figure 7 The positioning block 27 has a crosshair. Adjust the crosshair of the laser level 26 to coincide with the crosshair on the positioning block 27. During the moving and installation of the fixture (first support 5), observe whether the crosshair on the positioning block 27 coincides with the crosshair of the laser level 26. If they coincide, fix the reference rail 1. If they do not coincide, adjust according to the offset of the crosshair until they coincide, and then fix the reference rail 1.

[0028] like Figure 4 and Figure 5As shown, the auxiliary guide rail mounting fixture includes a second support base 24, a third support base 19, and an adjusting screw 15. Both the second support base 24 and the third support base 19 are equipped with an upper positioning support wheel 21, a side positioning support wheel 22, and a locking support wheel 23. The second support base 24 and the third support base 19 are respectively mounted on the base rail 1 and the auxiliary guide rail 2 via their respective components. The upper positioning support wheel 21 rests against the top surface of the base rail 1 or the auxiliary guide rail 2, while the side positioning support wheel 22 and the locking support wheel 23 rest against the two sides of the base rail 1 or the auxiliary guide rail 2, clamping them onto the base rail 1 or the auxiliary guide rail 2. An adjusting screw 15 is provided between the second support seat 24 and the third support seat 19. A first screw support seat 25 is provided on the second support seat 24, and a second screw support seat 20 is provided on the third support seat 19. A nut is provided inside the second screw support seat 20, and the adjusting screw 15 is connected to this nut, with one end connected to the first screw support seat 25. The adjusting screw 15 rotates and moves to adjust the distance between the second support seat 24 and the third support seat 19, which is the distance between the baseline rail 1 and the secondary rail 2. A locking nut 16 is also provided on the adjusting screw 15. After the distance between the baseline rail 1 and the secondary rail 2 is adjusted, the locking nut 16 fixes the adjusting screw 15 so that it no longer rotates. A guide rod 17 is also provided between the second support 24 and the third support 19. The guide rod 17 is mounted on the third support 19 through the guide rod base 18. The second support 24 is provided with a guide hole. The guide rod 17 extends into the guide hole and moves in the guide hole, playing a guiding role when the adjusting screw 15 drives the third support 19 to move.

[0029] The usage process of the above-mentioned auxiliary rail installation fixture is as follows.

[0030] See Figure 6 After the baseline rail 1 is installed, place the secondary rail 2 on the secondary rail base plate 4 (e.g., Figure 1 (As shown). The second support seat 24 is placed on the baseline rail 1. The adjusting screw 15 is rotated so that the third support seat 19 can be placed on the secondary rail 2. The adjusting screw 15 is rotated again to adjust the installation center distance between the baseline rail 1 and the secondary rail 3 to L. Then, one end of the secondary rail 2 is fixed in position. The upper positioning support wheel 21 and the side positioning support wheel 22 on the second support seat 24 are close to the baseline rail 1, and the locking support wheel 23 is close to the baseline rail 1. The second support seat 24 is locked onto the baseline rail 1 by adjusting the position of the nut, with the side and top surfaces of the baseline rail 1 as the reference surfaces. Then, the upper positioning support wheel 21 and the side positioning support wheel 22 on the third support seat 19 are placed on the secondary rail 2, and the locking support wheel 23 is close to the secondary rail 2. The third support seat 19 is locked onto the secondary rail 2 by adjusting the position of the nut, and the nut on the screw is also tightened. In this way, the center distance L between the baseline rail 1 and the secondary rail 2 is fixed to a certain value, which also ensures the straightness and flatness of the secondary rail 2.

[0031] See Figure 7 The laser level 26 can be placed on the secondary rail base plate 4, and a positioning block 27 with crosshairs can be placed on the third support 19. When moving the second support 24 and the third support 19, it is checked whether the position of the crosshairs of the laser level 26 coincides with the crosshairs on the positioning block 27. If they coincide, the secondary rail 2 is fixed. If they do not coincide, the adjustment is made according to the offset position until they coincide.
