[0006] A straightening mechanism is arranged on the top of the machine tool table, and the straightening mechanism includes a rubber plate, a straightening plate, a slider and an installation groove. An installation groove is opened on the top of the machine tool table, the inner wall of the installation groove is slidably connected with the slider, the top of the slider is fixedly installed with the straightening plate, and a rubber plate is fixedly installed on one side of the straightening plate. The rubber plate is used for straightening the joint of the first guide rail and the second guide rail.

[0007] In one example, an electric motor is fixedly installed on one side of the inner wall of the installation groove, a lead screw is fixedly installed on the output shaft of the electric motor, and the lead screw is in threaded connection with the slider.

[0008] In one example, a baffle is fixedly installed on the other side of the top of the machine tool table, a rubber pad is fixedly installed on one side of the baffle, and the rubber pad is attached to the joint of the first guide rail and the second guide rail.

[0009] In one example, clamping grooves are opened on one side of the first guide rail and the second guide rail.

[0010] In one example, clamping blocks are fixedly installed on the other side of the first guide rail and the second guide rail, and the sizes of the clamping blocks are adapted to the clamping grooves.

[0011] In one example, a plurality of installation holes are opened on the tops of the first guide rail and the second guide rail, and fastening screws are in threaded connection with the inner walls of the plurality of installation holes.

[0012] A linear guide rail for a splicing type numerical control machine tool proposed by the present utility model can bring the following beneficial effects:

[0013] 1. For this linear guide rail for a splicing type numerical control machine tool, by restarting the electric motor to drive the screw rod to rotate, the slider is driven to move in the installation groove, and the marking straight plate will be driven to move. At this time, the rubber plate will be driven to straighten the joint of the first guide rail and the second guide rail, avoiding unevenness after their engagement, and thus straightening it through the marking straight plate to make its installation neater.

[0019] In order to more clearly illustrate the overall concept of the present utility model, the following is a detailed description by way of example in conjunction with the drawings of the specification.

[0020] As Figures 1 to 3 shown, an embodiment of the present utility model proposes a linear guide rail for a splicing type numerical control machine tool, including a machine tool table 1, and a first guide rail 2 and a second guide rail 4 are fixedly arranged on the top of the machine tool table 1;

[0021] A straightening mechanism is arranged on the top of the machine tool table 1, and the straightening mechanism includes a rubber plate 7, a marking straight plate 8, a slider 9 and an installation groove 12. An installation groove 12 is opened on the top of the machine tool table 1, the inner wall of the installation groove 12 is slidably connected with a slider 9, a marking straight plate 8 is fixedly installed on the top of the slider 9, and a rubber plate 7 is fixedly installed on one side of the marking straight plate 8. The rubber plate 7 is used for straightening the connection between the first guide rail 2 and the second guide rail 4.

[0022] Specifically, an electric motor 11 is fixedly installed on one side of the inner wall of the installation groove 12. A lead screw 10 is fixedly installed on the output shaft of the electric motor 11, and the lead screw 10 is in threaded connection with the slider 9. By driving the lead screw 10 to rotate through the electric motor 11, the lead screw 10 drives the slider 9 to move in the installation groove 12, and drives the marking straight plate 8 to be straight when it is installed.

[0023] Specifically, a baffle 6 is fixedly installed on the other side of the top of the machine tool table 1. A rubber pad 13 is fixedly installed on one side of the baffle 6, and the rubber pad 13 is attached to the connection part of the first guide rail 2 and the second guide rail 4. By fixing the rubber pad 13 through the baffle 6, the installation part of the first guide rail 2 and the second guide rail 4 is partitioned, and the other side is made straight.

[0024] Specifically, clamping grooves 5 are formed on one side of each of the first guide rail 2 and the second guide rail 4. The first guide rail 2 and the second guide rail 4 are clamped and connected through the clamping of the clamping grooves 5 and the clamping blocks 3.

[0025] Specifically, clamping blocks 3 are fixedly installed on the other side of each of the first guide rail 2 and the second guide rail 4, and the clamping blocks 3 are adapted to the clamping grooves 5 in size. The first guide rail 2 and the second guide rail 4 are connected through the clamping connection of the clamping blocks 3 and the clamping grooves 5.

[0026] Specifically, a plurality of installation holes 14 are formed in the tops of the first guide rail 2 and the second guide rail 4. The inner walls of the plurality of installation holes 14 are all in threaded connection with fastening screws 15. The fastening screws 15 are fixed through the installation holes 14, and the fastening screws 15 are used to install the guide rails.

[0027] Working principle: Connect both the first guide rail 2 and the second guide rail 4 to the rubber pad 13 on the baffle 6, and make the clamping grooves 5 and the clamping blocks 3 in clamping connection. Then start the electric motor 11 to drive the lead screw 10 to rotate, which drives the slider 9 to move in the installation groove 12, and drives the marking straight plate 8 to move. At this time, it will drive the rubber plate 7 to straighten the clamping part of the first guide rail 2 and the second guide rail 4, and prevent it from being uneven after clamping. Thus, it is straightened through the marking straight plate 8 to make it more neat when installed. After straightening, install the fastening screws 15 into the installation holes 14 one by one to fix the first guide rail 2 and the second guide rail 4 on the machine tool table 1.
