Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Specific Implementation Example 1: Please refer to Figure 1-5As shown, this utility model is a clamp for drilling linear guide rails, including a guide rail clamp 1, an extension support guide seat 2, and an adjustable support 3. The adjustable support 3 is installed on the lower surface of the extension support guide seat 2. The extension support guide seat 2 is inserted into the end of the guide rail clamp 1 and fixed by two first bolts to achieve extended support for the linear guide rail. The extension support guide seats 2 are inserted into each other and fixed by two first bolts. The multiple extension support guide seats 2 at both ends of the guide rail clamp 1 combine to achieve ultra-long extension support for the linear guide rail, so as to meet the clamping needs of drilling ultra-long guide rails.

[0027] The guide rail fixture 1 includes a horizontal base plate 11. Two pairs of U-shaped slots 12 for mounting and fixing are provided on the side of the horizontal base plate 11. T-bolts and nuts are placed in the U-shaped slots 12 to connect and fix the horizontal base plate 11 to the machine tool platform. A fixed clamping block 13 is fixed to the upper surface of the horizontal base plate 11. A row of cylinder mounting seats 14 is fixed to the side wall of the horizontal base plate 11 opposite to the fixed clamping block 13. A double-rod cylinder 15 is mounted on the cylinder mounting seat 14. A movable clamping block 16 is mounted on the telescopic end plate of the double-rod cylinder 15. The sides of the fixed clamping block 13 and the movable clamping block 16 opposite to each other are provided with protrusions that fit the grooves on the side of the linear guide rail, achieving stable clamping of the linear guide rail. A chip removal groove 17 is provided on the upper surface of the horizontal base plate 11, parallel to the fixed clamping block 13. Two rectangular insertion holes 18 are respectively opened at both ends of the horizontal base plate 11 to mate with the extension support guide seat 2, and a first through hole 19 communicating with the rectangular insertion holes 18 is opened on the bottom surface of the horizontal base plate 11. One end of the extension support guide seat 2 is inserted into the two rectangular insertion holes 18 at the end of the horizontal base plate 11 and fixed by two first bolts. The surface of the horizontal base plate 11 has a rectangular groove 110 that mates with the telescopic end plate of the double-rod cylinder 15, which facilitates placing the movable clamping block 16 in the middle of the telescopic end plate of the double-rod cylinder 15, and helps to ensure stable clamping. The telescopic control of the double-rod cylinder 15 controls the clamping action of the linear guide rail.

[0028] The extended support guide seat 2 includes a rectangular groove 21 with an upper opening. A row of idler rollers 22 is mounted on the rectangular groove 21. Two rectangular plugs 23 are fixed at one end of the rectangular groove 21, which are inserted into rectangular insertion holes 18. A threaded through hole 24 for engaging with a first bolt is opened in the middle of the rectangular plug 23. Two second rectangular insertion holes 25 are opened at the other end of the rectangular groove 21, which are inserted into the rectangular plugs 23. Two second circular through holes 26 are opened on the bottom surface of the same end of the rectangular groove 21 and the second rectangular insertion holes 25.

[0029] The adjustable support 3 includes a flange 31 that connects and mates with the extension support guide seat 2. An internally threaded cylinder 32 is fixed to the lower surface of the flange 31. A threaded post 33 is threadedly connected to the lower end of the internally threaded cylinder 32. A cylindrical rod 34 is fixed to the lower end of the threaded post 33. A tapered base 35 is rotatably mounted on the lower end of the cylindrical rod 34 via a bearing. To facilitate the rotation of the cylindrical rod 34 for adjusting the overall support height and to position the adjusted threaded post 33 relative to the internally threaded cylinder 32, a ring of evenly distributed handle rods 36 is fixed to the circumference of the cylindrical rod 34, reducing the difficulty of rotation by rotating the handle rods 36. A locking nut is threadedly connected to the threaded post 33. After the threaded post 33 is adjusted, the locking nut is tightened onto the internally threaded cylinder 32 to stabilize the threaded post 33.

[0030] After the extended support guide seat 2 is installed at the end of the guide rail clamp 1, a row of rollers 22 installed on it is tangent to the surface of the horizontal base plate 11 on which the linear guide rail is placed, which effectively avoids the gravity deformation of the long linear guide rail, ensures the stable clamping of the linear guide rail in the guide rail clamp 1, and effectively ensures the accuracy of the opening position.

[0031] The extension support guide seat 2 is quick and easy to install at the end of the guide rail fixture 1. The adjustable support 3 ensures that the extension support guide seat 2 is level, which is suitable for most machine tools.
