[0002] A gantry milling machine, or simply gantry milling machine, is a milling machine with a gantry frame and a horizontal long bed. Multiple milling cutters can be used simultaneously to machine surfaces on a gantry milling machine, resulting in high machining accuracy and production efficiency. It is suitable for machining large workpieces' planes and inclined surfaces in batch and mass production. CNC gantry milling machines can also machine spatial curved surfaces and some special-shaped parts.

[0003] The tool post of a gantry milling machine is mostly fixed on a worktable that slides with the guide rail, and a fixing nut that is threaded with the lead screw is installed on the worktable. The tool post can be driven to slide by the lead screw. However, after long-term use, the guide rail and the slide block are prone to deviation, which increases the gap between them and affects the guiding accuracy of the guide rail, thus affecting the machining of parts.

[0004] Existing guide rail clearance adjustment components lack a warning function, and the problem is usually only discovered after the guide rail and slider have worn significantly. Adjustment is typically done by pre-tightening, which is inconvenient and greatly reduces the service life of the guide rail. Therefore, a guide rail clearance adjustment component for gantry milling machines is proposed to solve the problems mentioned above. Utility Model Content

It features wear warning and easy adjustment, solving the problem that existing guide rail clearance adjustment components lack warning functions, are usually only discovered after the guide rail and slider have worn significantly, and are typically adjusted using a pre-tightening method, which is inconvenient and greatly reduces the service life of the guide rail.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustment component for the guide rail clearance of a gantry milling machine, including a guide rail, a slider slidably mounted on the top of the guide rail, a mounting base provided at the bottom of the guide rail, a sensing component provided inside the mounting base, and two sealing cavities provided inside the guide rail, each of the two sealing cavities being provided with an adjustment structure.

[0009] Furthermore, the bottom of the guide rail is fixedly connected to the inner side of the mounting base, and the number of the sensing components is set to multiple sets, with the multiple sets of sensing components symmetrically distributed on both sides of the slider.

[0010] Furthermore, the connecting frame is fixedly connected to the outer side of the connecting piece, and the outer wall of the pulley is in contact with the outer wall of the slider.

[0016] Compared with the prior art, this utility model provides an adjustment component for the guideway clearance of a gantry milling machine, which has the following advantages:

[0017] 1. This adjustment component for the guide rail clearance of a gantry milling machine, through the setting of the sensing component, when the slider deviates, the slider pushes the sensing component on the deviated side to move, so that the pressure sensor on that side receives pressure and sends a signal to the external main controller. The external main controller displays abnormal information to remind the operator, so that the operator can know that the slider has deviated at the first time, thereby stopping the machine in time, reducing further wear, and helping to extend the service life of the guide rail.

[0018] 2. This adjustment component for the guide rail clearance of a gantry milling machine, when the slider deviates, supplies gas into the sealed cavity on the side away from the slider deviation. Under the push of the air pressure, the top block moves, causing the top block on the other side to correct the slider position. This ensures stable cooperation between the slider and the guide rail, facilitates adjustment, enables the guide rail to guide stably, and guarantees the machining accuracy of the product.

[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 protection scope of the present utility model.

[0026] Please see Figures 1 to 5The adjustment component for the guide rail clearance of the gantry milling machine in this embodiment includes a guide rail 1, a slider 2 slidably mounted on the top of the guide rail 1, and a mounting base 3 provided at the bottom of the guide rail 1. The bottom of the guide rail 1 is fixedly connected to the inner side of the mounting base 3. A sensing component is provided inside the mounting base 3. The sensing component includes a connecting piece 4 provided inside the mounting base 3. A connecting frame 5 is provided on the side of the connecting piece 4 near the slider 2. The connecting frame 5 is fixedly connected to the outer side of the connecting piece 4. A pulley 6 is rotatably mounted on the inner side of the connecting frame 5. The outer wall of the pulley 6 is in contact with the outer wall of the slider 2. A first support spring 7 and a pressure sensor 8 are respectively provided on the side of the connecting piece 4 away from the slider 2. One end of the first support spring 7 is fixedly connected to the connecting piece 4, and the other end of the first support spring 7 is fixedly connected to the inside of the mounting base 3. The pressure sensor 8 is fixedly installed inside the mounting base 3, and a gap is left between the pressure sensor 8 and the connecting piece 4. When slider 2 deviates, slider 2 presses the pulley 6 in the sensing component on the deviated side and pushes the connecting piece 4 to press the first support spring 7, so that the connecting piece 4 contacts the pressure sensor 8. The pressure sensor 8 is connected to the external main controller. When the pressure sensor 8 is under pressure, it sends a signal to the external main controller. The external main controller displays abnormal information to remind the staff, so that the staff can know that slider 2 has deviated at the first time, thereby stopping the machine in time and reducing further wear.

[0027] The number of sensing components is set to multiple sets, which are symmetrically distributed on both sides of the slider 2, so as to realize the deviation of the slider 2 from both sides.

[0028] To facilitate gap adjustment, the guide rail 1 has two sealed cavities 9. Each sealed cavity 9 contains an adjustment structure, including a movable piece 10 inside the cavity. A top block 11 extending outwards from the side of the movable piece 10 near the slider 2 extends to the outside of the guide rail 1. A second support spring 12 is located on the same side of the movable piece 10 near the top block 11, inside the sealed cavity 9. The end of the second support spring 12 away from the movable piece 10 is fixedly connected to the inside of the sealed cavity 9. An air supply hole 13 is located on the side of the sealed cavity 9 away from the top block 11. The air supply hole 13 can be connected to an external air pipe and air supply equipment to supply gas into the sealed cavity 9. Under air pressure, the movable piece 10 moves, causing the top block 11 to move as well, simultaneously compressing the second support spring 12. When gas is extracted from the sealed cavity 9, the second support spring 12 releases its elasticity, resetting the top block 11, thus adjusting its position. When slider 2 deviates, gas is supplied into the sealed cavity 9 on the side away from slider 2, causing the top block 11 on the other side to move and correct the position of slider 2, thus ensuring stable cooperation between slider 2 and guide rail 1.

[0029] It should be noted that sealing strips 14 adapted to the inner wall of the sealing cavity 9 are provided on both the upper and lower sides of the movable piece 10, ensuring the sealing performance of the movable piece 10.

[0030] The working principle of the above embodiments is as follows:

[0031] When slider 2 deviates during use, it presses the pulley 6 in the sensing component on the deviated side and pushes the connecting piece 4 to press the first support spring 7, causing the connecting piece 4 to contact the pressure sensor 8. The pressure sensor 8 is connected to the external controller. When pressure is applied, the pressure sensor 8 sends a signal to the external controller, which displays an abnormal message to alert the operator. This allows the operator to know immediately that slider 2 has deviated. When slider 2 deviates, gas is supplied to the sealed cavity 9 on the side away from the deviated slider 2. Under the pressure of the gas, the movable piece 10 moves and the top block 11 moves, causing the top block 11 on the other side to correct the position of slider 2.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects. The above descriptions are specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and concept of this application, should be covered within the protection scope of the claims of this utility model.
