Description

Technical Field

[0001] This utility model relates to the technical field of beam lifting mechanisms, and in particular to a beam lifting mechanism for a gantry machining center. Background Technology

[0002] The beam lifting mechanism of a gantry machining center is a crucial component. It primarily controls the raising and lowering of the machining center's beam to adjust the worktable or workpiece to a suitable machining position. The beam lifting mechanism directly affects the machining center's accuracy, stability, and processing efficiency. Furthermore, it must possess good rigidity and vibration resistance to ensure stable operation under high-load, high-precision working conditions.

[0003] However, in the existing gantry machining center, the guide rail frame is in the open state when the beam lifting mechanism is in use, which makes it easy for debris to enter the lifting mechanism, causing system pollution and increasing maintenance costs. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This utility model provides a beam lifting mechanism for a gantry machining center, which has the following advantages:

[0016] 1. The beam lifting mechanism of this gantry machining center, through the setting of the winding assembly and the curtain, when in use, the drive motor is started, which drives the lifting screw to move the slider up and down within the guide rail frame. This causes the curtains on the top and bottom surfaces of the slider to slide within the grooves on the guide rail frame. Subsequently, one end of the rotating shaft rotates on the inner wall of the guide rail frame, and the other end rotates within the support shell. The rotation of the rotating shaft causes the spring to deform within the support shell, generating elastic force. When the slider rises and falls, the spring drives the rotating shaft to wind up the curtain, thereby ensuring that the guide rail frame remains in a closed state during the beam lifting process. This prevents debris from entering the lifting mechanism, keeps the system clean, and reduces maintenance costs.

[0017] 2. The beam lifting mechanism of this gantry machining center, through the arrangement of telescopic components, support plates, and rollers, allows the lifting screw to drive the slider to slide and rise within the guide rail frame during the lifting of the main beam. This causes the rollers to roll on the inner wall of the guide rail frame. Simultaneously, as the rollers press against the inner wall of the guide rail frame, the inner wall of the guide rail frame exerts a reaction force on the rollers, pushing the support plate and compressing the support spring. This causes the support spring to deform under force and generate elastic force, and the positioning rod slides and positions itself on the side of the slider. This enhances the stability of the beam lifting, reduces friction, prevents damage to the lifting screw, and improves the service life and stability of the beam lifting mechanism.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 4This utility model provides a technical solution: a crossbeam lifting mechanism for a gantry machining center, comprising two sets of sliders 1. A curtain 2 is fixedly connected to the top and bottom surfaces of each slider 1. A winding assembly 3 is fixedly connected to one end of each curtain 2. Through the arrangement of the winding assembly 3 and the curtain 2, the guide rail frame 14 remains closed during the lifting process of the crossbeam, preventing debris from entering the lifting mechanism, maintaining system cleanliness, and reducing maintenance costs. Four sets of telescopic assemblies 4 are fixedly connected to both sides of each slider 1. Through the arrangement of the telescopic assemblies 4, support plates 5, and rollers 6, the crossbeam lifting mechanism is strengthened. The stability of the beam during lifting and lowering reduces friction and avoids damage to the lifting screw 11, thus improving the service life and stability of the beam lifting mechanism. One end of the telescopic component 4 is fixedly connected to a support plate 5, and four sets of rollers 6 are rotatably connected to the surface of the support plate 5. The winding component 3 includes a rotating shaft 301 fixedly connected to one end of the curtain 2. One end of the rotating shaft 301 is clamped with a spring 302, and one end of the spring 302 is clamped with a support shell 303. The telescopic component 4 includes a support spring 401 fixedly connected to both sides of the slider 1, and a positioning rod 402 is sleeved inside the support spring 401.

[0025] One side of each of the two sets of sliders 1 is fixedly connected to a connecting plate 7, and another connecting plate 8 is fixedly installed on one side of the connecting plate 7 by bolts. The connecting plate 8 serves to connect the main body of the crossbeam 9.

[0026] A crossbeam body 9 is fixedly connected to one side of the connecting plate 2 8, and several sets of stress plates 10 are fixedly connected to the top of the crossbeam body 9. The stress plates 10 are used to increase the stability of the support.

[0027] The two sets of sliders 1 are internally threaded with lifting screws 11, and the top of the lifting screws 11 is fixedly connected with a drive motor 12. The drive motor 12 drives the lifting screws 11 to rotate.

[0028] A motor housing 13 is fitted onto the surface of the drive motor 12, and a guide rail 14 is fixedly connected to the top of the motor housing 13. The guide rail 14 provides support.

[0029] The inner wall of the guide rail frame 14 is provided with a sliding groove that matches the curtain 2. The support shell 303 is fixedly connected to the inner wall of the guide rail frame 14. The sliding groove facilitates the sliding of the curtain 2 and limits its position.

[0030] A movable frame 15 is fixedly connected to one side of the main beam 9, and a processing head 16 is provided on one side of the movable frame 15. The processing head 16 facilitates the processing of products.

[0031] In this invention, the working steps of the device are as follows:

[0032] First step: When in use, start the drive motor 12, drive the lifting screw 11 to drive the slider 1 to slide and rise within the guide rail frame 14, so that the curtains 2 on the top and bottom surfaces of the slider 1 slide in the grooves on the guide rail frame 14, and then one end of the rotating shaft 301 rotates on the inner wall of the guide rail frame 14.

[0033] Second step: The other end rotates inside the support shell 303. The rotation of the shaft 301 causes the spring 302 to deform inside the support shell 303 and generate elastic force. When the slider 1 rises and falls, the spring 302 drives the shaft 301 to roll up the curtain 2.

[0034] Third step: When the main body 9 of the crossbeam is raised and lowered, the lifting screw 11 drives the slider 1 to slide and rise and fall inside the guide rail frame 14, so that the roller 6 rolls on the inner wall of the guide rail frame 14. At the same time, because the roller 6 is pressed against the inner wall of the guide rail frame 14, the inner wall of the guide rail frame 14 has a reaction force on the roller 6, which pushes the support plate 5 and squeezes the support spring 401, so that the support spring 401 is deformed by force and generates elastic force, and the positioning rod 402 slides and positions itself on the side of the slider 1.
