After the columns on both sides are welded and fixed, the deformation is large. The original designed roller guide rail slider assembly needs to be adjusted by gaskets to absorb welding errors, and the adjustment is relatively difficult. Summary of the Invention

[0003] Utility Model Purpose: In order to overcome the deficiencies of the background technique, the utility model discloses a slide rail device for absorbing welding errors.

[0004] Technical Solution: In the slide rail device for absorbing welding errors of the utility model, the first column and the second column are arranged side by side at intervals, and a slide rail profile is arranged in the middle;

[0005] A guide rail is longitudinally fixed on the first column, a slider is fixed on one side of the slide rail profile, and the slider is embedded in the guide rail and slidably connected thereto;

[0006] A slide rail is longitudinally fixed on the second column, a chute is opened on the surface of the slide rail, a roller is arranged on the other side of the slide rail profile, the roller is embedded in the chute and rolls longitudinally, and the depth of the chute is greater than the thickness of the roller. The slide rail profile is provided with a waist-shaped hole for fixing the roller, and the waist-shaped hole extends along the width direction of the chute.

[0007] Further, the first column and the second column are fixed to the bottom plate and fixedly connected through a top plate on one side.

[0008] Further, the slider fits with the inner groove of the guide rail and slides seamlessly.

[0009] Further, the roller is connected to a roller shaft, and the roller shaft passes through the waist-shaped hole and is locked by a flat washer, a stop washer and a nut.

[0010] Further, a plurality of rollers and sliders are arranged at intervals on the slide rail profile.

[0011] Further, limit blocks are arranged at the top and bottom of the guide rail and the slide rail.

[0012] Beneficial Effects: Compared with the prior art, the advantages of the utility model are as follows: The slide rail profile is provided with a fixed side and a flexible adjustable side, which can absorb welding errors, ensure the structural accuracy, and solve the problem of difficult adjustment. Description of the Drawings

[0013] Figure 1 It is the front view of the utility model;

[0014] Figure 2 This is the top view sectional drawing of the utility model. Specific embodiments

[0015] The technical solutions of the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] As Figure 1 and 2 shown in the slide rail device for absorbing welding errors, the first column 1 and the second column 2 are arranged in parallel at intervals, with a slide rail profile 3 in the middle. The first column 1 and the second column 2 are fixed to the bottom plate 10 and are fixedly connected through the top plate on one side.

[0017] A guide rail 4 is longitudinally fixed (in the Z-axis direction) on the first column 1. A slider 5 is fixed on one side of the slide rail profile 3. The slider 5 is embedded in the guide rail 4 and is slidably connected thereto; the slider 5 fits with the inner groove of the guide rail 4 and slides seamlessly.

[0018] A slide rail 6 is longitudinally fixed on the second column 2. A chute 7 is opened on the surface of the slide rail 6. A roller 8 is provided on the other side of the slide rail profile 3.
