Technical Field

[0001] This invention relates to the field of machining center drive components, and in particular to a beam drive device for a gantry machining center. Background Technology

[0002] A gantry machining center is a large CNC machining equipment. Its main feature is that the Z-axis of the spindle is set perpendicular to the worktable. The overall structure consists of a portal frame made up of two columns and a top beam, with a crossbeam in the middle of the two columns.

[0003] A Chinese patent with publication number CN101653842B discloses a multi-spindle CNC machining center. The invention includes a control cabinet and a milling machine. The control cabinet is connected to the milling machine through a control system disposed therein. The milling machine includes a machine tool frame and a machining mechanism disposed on the machine tool frame. The machine tool frame includes a bed and a gantry mounted on the bed. The gantry includes a crossbeam placed horizontally above the bed and columns disposed on both sides of the bed. The crossbeam is fixed to the upper part of the columns. The machining mechanism includes a drive device and a spindle device for milling. The drive device includes an X-axis drive device, a Y-axis drive device, and a Z-axis drive device.

[0004] Regarding the aforementioned technologies, it has been found that most existing machining centers use ball screws as the direct drive structure. This method is constrained by the screw pitch during the drive process and cannot achieve precise adjustment. Summary of the Invention

[0005] This invention solves the problems in related technologies and proposes a beam drive device for gantry machining centers.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a beam drive device for a gantry machining center, comprising a top shell, two slide rails fixedly mounted on the top shell, a matching movable slider slidably mounted on the slide rails, a lead screw assembly disposed in the top shell, a matching nut seat mounted on the lead screw assembly, a connecting frame fixedly mounted on the upper end of the nut seat, a horizontal guide rail fixedly disposed in the top shell, a drive plate disposed in the middle of the horizontal guide rail, auxiliary seats slidably engaged with the horizontal guide rails at both ends of the drive plate, the auxiliary seats being rotatably connected to the drive plate, and a locking component fixedly mounted on the auxiliary seat, the locking component being used to restrict the rotation of the drive plate and the auxiliary seat or to restrict the movement of the drive plate on the horizontal guide rail, a linkage frame connected to the drive plate disposed on the connecting frame, and a traveling seat connected to the movable slider disposed at the head of the drive plate.

[0007] By adopting the above technical solution, two slide rails are fixedly installed on the top shell of the machining center, and a movable slider is slidably installed on the slide rails. This ensures that the movable slider can be flexibly adjusted during use. To drive the movable slider's movement, a corresponding lead screw assembly is installed below, fixedly installed in the top shell, and fitted with a matching nut seat. During use, the lead screw assembly drives the nut seat to move stably. The nut seat is connected to the drive plate via a connecting frame and a linkage frame, enabling the drive plate to move on the horizontal guide rail. When the traveling seat is installed at the head of the drive plate, it can move synchronously, driving the movable slider to slide on the slide rail. Auxiliary seats are provided at both ends of the drive plate, allowing it to slide stably on the horizontal guide rail. The drive plate can also rotate with the auxiliary seats. A locking component is fixedly installed on the auxiliary seats, allowing for either locking the drive plate's rotation or locking the sliding motion, thus enabling two usage modes for the drive plate.

[0008] As a preferred embodiment, the connecting frame includes an arc-shaped seat, a vertical frame, and a horizontal plate. The arc-shaped seat is fixedly installed on the lower end face of the vertical frame, and the two ends of the arc-shaped seat are provided with mating holes for connecting with nut seats. The horizontal plate is vertically installed on one side of the vertical frame, and the horizontal plate is integrally formed with the vertical frame. A reinforcing corner plate is also fixedly installed between the vertical frame and the horizontal plate.

[0009] By adopting the above technical solution, the structural design of the connecting frame ensures that the vertical frame can be installed on the nut seat through the arc-shaped seat, and the mating holes facilitate the connection and fixation by bolts. The horizontal plate ensures that it can be stably placed on the upper surface of the nut seat during installation, which facilitates quick positioning of the connecting frame during installation and ensures a more stable connection between the connecting frame and the nut seat. The reinforcement angle plate increases the strength between the vertical frame and the horizontal plate.

[0010] As a preferred embodiment, the drive board includes a main board section, a lower rod section, and a top frame section. The lower rod section is fixedly installed at the lower end of the main board section, and both ends of the lower rod section extend out from both sides of the main board section. The top frame section includes upright plates and connecting shafts. There are two upright plates, and the two upright plates are symmetrically arranged at the head of the main board section. The connecting shaft is fixedly installed between the two upright plates. Side shafts connected to auxiliary seats are provided on both sides of the main board section, and the side shafts are integrally formed with the main board section.

[0011] By adopting the above technical solution, the drive board is designed with a main board section, a lower rod section, and a top frame section that cooperate. When easy to use, the main board section can be connected to the linkage frame through the lower rod section. The parts of the lower rod section that extend from both sides of the main board section can be engaged with the linkage frame. At the same time, the main board section cooperates with the traveling seat through the top frame section to achieve the purpose of driving the traveling seat to move stably. By setting side shafts on both sides of the main board section, it is convenient to rotatably connect with the auxiliary seat through the side shafts.

[0012] As a preferred embodiment, the horizontal guide rail includes a track seat and a positioning horizontal rail. The track seat is fixedly installed in the top shell, and the positioning horizontal rail is symmetrically arranged on the upper end face of the track seat.

[0013] By adopting the above technical solution, the structure of the horizontal guide rail is designed to ensure that the positioning horizontal rail can be stably installed in the top shell through the rail seat, and the auxiliary seat can be stably installed through the positioning horizontal rail. During use, the position of the drive board can be changed by adjusting the position of the auxiliary seat on the positioning horizontal rail.

[0014] As a preferred embodiment, the auxiliary seat includes a seat plate and a limiting slider that is slidably mounted in the positioning rail. The seat plate is rotatably mounted on a side shaft, and the seat plate has a threaded hole that mates with the locking assembly. The limiting slider is disposed on the outer side of the seat plate and is integrally formed with the seat plate.

[0015] By adopting the above technical solution, the structure of the auxiliary seat is designed to ensure that a limiting slider is installed on the seat plate, and the limiting slider is used to slide and install the auxiliary seat in the positioning rail. At the same time, by opening threaded holes on the seat plate, it is easy to connect and fix the auxiliary seat with bolts.

[0016] As a preferred embodiment, the locking assembly includes a main body shell, a threaded rod assembly, a synchronizing frame, a locking frame, and a drive electric cylinder. The main body shell is fixedly mounted on the base plate. The threaded rod assembly is threadedly connected to the main body shell, and the head of the threaded rod assembly contacts the side shaft. The synchronizing frame is sleeved on the end of the threaded rod assembly. The locking frame is mounted on the outer surface of the main body shell and is longitudinally slidably connected to the main body shell. The drive electric cylinder is fixedly mounted on the main body shell, and the output end of the drive electric cylinder is connected to the locking frame.

[0017] By adopting the above technical solution, the structure of the locking assembly is designed to ensure that the threaded rod assembly, the synchronizing frame, the locking frame, and the drive cylinder are installed on the main body shell. During use, the threaded rod assembly can be rotated to press against one end of the side shaft, thus preventing the side shaft from rotating normally and allowing the drive plate to slide stably horizontally. The synchronizing frame and the locking frame ensure that the drive plate can move up and down during use via the drive cylinder. When the locking frame presses against the positioning rail, it can lock the horizontal movement of the drive plate, ensuring that the drive plate can only be adjusted by rotating the side shaft, thereby realizing two driving methods for the drive plate.

[0018] As a preferred embodiment, the main body shell includes a shell, a top plate, and a threaded sleeve for mounting the threaded rod assembly. The top plate is disposed on the upper end face of the shell and is integrally formed with the shell. The threaded sleeve and the outer side of the shell are provided with a vertical rail shell for sliding installation of the locking frame. The vertical rail shell is fixedly connected to the shell.

[0019] By adopting the above technical solution, the structure of the main shell is designed to ensure that the top plate is fixedly installed on the shell, which facilitates the installation of the drive electric cylinder. This ensures that the drive electric cylinder can be stably driven during use. At the same time, by fixing a threaded sleeve in the middle of the shell, the threaded rod assembly can pass through the threaded sleeve for connection, ensuring that the purpose of the threaded rod assembly in the threaded sleeve can be adjusted by rotation during use. By fixing a vertical rail shell on the outer side, the locking frame can be slidably installed through the vertical rail shell during use.

[0020] As a preferred embodiment, the synchronization frame includes a collar and a connecting frame. The connecting frame is integrally formed on the outer side of the collar. The inner side of the collar is also symmetrically provided with mating fingers. The end of the threaded rod assembly is provided with a mating groove corresponding to the mating fingers. The locking frame includes a sliding seat, a linkage outer rod, and a pressure seat. The sliding seat is slidably installed in the vertical rail housing. The linkage outer rod is vertically fixed on the outer side of the sliding seat and passes through the middle of the connecting frame. A brake plate is also fixedly installed on the lower end face of the pressure seat.

[0021] By adopting the above technical solution, the structure of the synchronization frame is designed to ensure that a collar can be fitted onto the end of the threaded rod assembly during use. The combination of a wrench and a groove ensures that the threaded rod assembly can be rotated and adjusted after the collar is fitted onto it. A connecting frame is provided on the collar to facilitate connection with the locking frame. The locking frame is designed to securely mount the linkage outer rod and the holding seat on the sliding seat, ensuring that the linkage outer rod and the holding seat can move synchronously under the drive of the sliding seat. When the sliding seat moves up and down, the linkage outer rod drives the synchronization frame to rotate, thereby driving the threaded rod assembly to rotate and adjust. Simultaneously, the holding seat can move the brake plate up and down. When moving downwards, the brake plate is pressed against the positioning rail, achieving rapid locking movement through friction.

[0022] As a preferred embodiment, the linkage frame includes a base frame, a tongue plate, a movable clamping shell, and a U-shaped plate that cooperates with the lower rod. The base frame is fixedly installed on the vertical frame. The tongue plate is integrally formed on the upper end face of the base frame. The movable clamping shell is slidably installed on the tongue plate, and a positioning frame is also fixedly installed on the tongue plate. A strip groove for the positioning frame to slide is opened on the movable clamping shell. A nut sleeve is fixedly installed on the outer side of the positioning frame. A matching positioning screw is installed in the nut sleeve. Several positioning holes corresponding to the positioning screws are evenly opened on the outer side of the movable clamping shell. The U-shaped plate is symmetrically arranged on both sides of the upper end face of the movable clamping shell, and the U-shaped plate is integrally formed with the movable clamping shell.

[0023] By adopting the above technical solution, the structure of the linkage frame is designed to ensure that the base frame is connected to the movable clamping shell via a tongue plate. Simultaneously, the positioning frame and slot allow the tongue plate to slide and adjust its position on the movable clamping shell, thereby changing the overall length of the linkage frame. After adjusting to the appropriate length, the positioning screw can be rotated to extend from the nut sleeve and inserted into the corresponding positioning hole for mutual locking. Furthermore, a U-shaped plate is provided on the upper surface of the movable clamping shell, ensuring that it can be clamped at both ends of the lower rod during installation. This allows the lower rod to move horizontally when the drive plate slides horizontally, and when the drive plate can only rotate, the lower rod can be offset and rotated using the U-shaped plate.

[0024] As a preferred embodiment, the traveling seat includes a traveling plate, a side plate, and an n-shaped seat that mates with a connecting shaft. The side plate is vertically installed on the rear end face of the traveling plate and is fixedly connected to the traveling plate. The n-shaped seat is fixedly installed in the middle of the lower end face of the traveling plate, and a diagonal brace is also fixedly installed between the n-shaped seat and the traveling plate.

[0025] By adopting the above technical solution, the structure of the walking seat is designed to ensure that the side plate and the n-shaped seat can be installed through the walking plate during use. During use, the n-shaped seat can be clamped and engaged with the connecting shaft at the lower end, while the side plate can be engaged and connected with the movable slider at the upper end, ensuring that the movable slider can move under the drive of the connecting shaft during use.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: By installing a connecting frame and a linkage frame on the nut seat of the lead screw assembly, the lower end of the drive plate can be moved by the connecting frame and the linkage frame when it is easy to use. The drive plate is mounted on the horizontal guide rail through an auxiliary seat. In normal use, the drive plate and the auxiliary seat can be locked together by a locking component. When the nut seat moves, the drive plate can slide on the horizontal rail, and then the movable slider on the slide rail can be moved by the traveling seat. When a small range of precise adjustment is required, the auxiliary seat and the horizontal guide rail can be locked together by the locking component. When the nut seat moves, the drive plate can be rotated by the linkage frame, and the displacement distance of the lower end of the drive plate can be transmitted to the upper end in a certain proportion, thereby amplifying the driving distance in a certain proportion, making it easier to drive and control.

[0056] Reference Figure 4 and Figure 5 As shown, a beam drive device for a gantry machining center includes a top shell 101, a horizontal guide rail 4 fixedly disposed in the top shell 101, a drive plate 5 disposed in the middle of the horizontal guide rail 4, and auxiliary seats 6 disposed at both ends of the drive plate 5 that slide in cooperation with the horizontal guide rail 4. The auxiliary seats 6 are rotatably connected to the drive plate 5, and a locking component 7 is fixedly installed on the auxiliary seats 6.

[0057] Reference Figure 13 , Figure 14 and Figure 15 As shown, the locking assembly 7 includes a main body housing 71, a threaded rod assembly 72, a synchronizing frame 73, a locking frame 74, and a drive electric cylinder 75. The main body housing 71 is fixedly mounted on the base plate 61. The threaded rod assembly 72 is threadedly connected to the main body housing 71, and the head of the threaded rod assembly 72 is in contact with the side shaft 511. The synchronizing frame 73 is sleeved on the end of the threaded rod assembly 72. The locking frame 74 is mounted on the outer side of the main body housing 71, and the locking frame 74 is longitudinally slidably connected to the main body housing 71. The drive electric cylinder 75 is fixedly mounted on the main body housing 71, and the output end of the drive electric cylinder 75 is connected to the locking frame 74. By designing the locking assembly 7, the threaded rod assembly 72, the synchronizing frame 73, the locking frame 74, and the drive cylinder 75 are installed on the main housing 71. During use, the threaded rod assembly 72 can be rotated to press against one end of the side shaft 511, thus preventing the side shaft 511 from rotating normally and allowing the drive plate 5 to slide stably horizontally. The synchronizing frame 73 and the locking frame 74 ensure that the drive plate 5 can move up and down via the drive cylinder 75 during use. When the locking frame 74 presses against the positioning rail 42, it locks the horizontal movement of the drive plate 5, ensuring that the drive plate 5 can only be adjusted by rotating via the side shaft 511, thereby achieving two driving modes for the drive plate 5.

[0058] Reference Figure 13 , Figure 14 and Figure 15As shown, the main body shell 71 includes a shell 711, a top plate 712, and a threaded sleeve 713 for mounting the threaded rod assembly 72. The top plate 712 is located on the upper end face of the shell 711 and is integrally formed with the shell 711. A vertical rail shell 714 for sliding mounting of the locking frame 74 is provided on the outer side of the shell 711 and is fixedly connected to the shell 711. The structural design of the main body shell 71 ensures that the top plate 712 is fixedly mounted on the shell 711, facilitating the fixed mounting of the drive cylinder 75 and ensuring stable operation of the drive cylinder 75 during use. Simultaneously, the threaded sleeve 713 fixedly mounted in the middle of the shell 711 allows the threaded rod assembly 72 to pass through the threaded sleeve 713 for connection, ensuring that the position of the threaded rod assembly 72 within the threaded sleeve 713 can be adjusted by rotation during use. The vertical rail shell 714 fixedly mounted on the outer side facilitates the sliding mounting of the locking frame 74 during use.

[0059] Reference Figure 13 , Figure 14 and Figure 15 As shown, the synchronizing frame 73 includes a collar 731 and a connecting frame 732. The connecting frame 732 is integrally formed on the outer surface of the collar 731. The inner surface of the collar 731 is also symmetrically provided with mating fingers 733. The end of the threaded rod assembly 72 is provided with a mating groove 721 corresponding to the mating fingers 733. The structure of the synchronizing frame 73 is designed to ensure that the collar 731 can be fitted onto the end of the threaded rod assembly 72 during use. The mating fingers 733 and the mating groove 721 ensure that the threaded rod assembly 72 can be rotated and adjusted after the collar 731 is fitted onto it. At the same time, the connecting frame 732 on the collar 731 facilitates the connection with the locking frame 74.

[0060] Reference Figure 13 , Figure 14 and Figure 15As shown, the locking frame 74 includes a sliding seat 741, a linkage outer rod 742, and a pressing seat 743. The sliding seat 741 is slidably installed in the vertical rail housing 714. The linkage outer rod 742 is vertically fixed to the outer surface of the sliding seat 741 and passes through the middle of the connecting frame 732. A brake plate 744 is also fixedly installed on the lower end face of the pressing seat 743. The structural design of the locking frame 74 ensures that the linkage outer rod 742 and the pressing seat 743 are fixedly installed on the sliding seat 741. This ensures that the linkage outer rod 742 and the pressing seat 743 can move synchronously under the drive of the sliding seat 741 during use. When the sliding seat 741 moves up and down, the linkage outer rod 742 can drive the synchronous frame 73 to rotate, thereby driving the threaded rod assembly 72 to rotate and adjust. At the same time, the pressing seat 743 can drive the brake plate 744 to move up and down. When moving downward, the brake plate 744 can be pressed onto the positioning horizontal rail 42, achieving rapid locking movement through friction.

[0061] Working principle: In actual use in the machining center, the drive electric cylinder can be activated to move the locking frame upward. The sliding seat drives the pressure seat and brake plate to move upward, separating the brake plate from the positioning horizontal rail. The linkage outer rod drives the threaded rod assembly to rotate forward, allowing the head of the threaded rod assembly to be stably pressed against the side shaft of the drive plate. The friction force fixes the side shaft and the threaded rod assembly together, so the drive plate cannot rotate through the side shaft. When the screw assembly is activated to drive the nut seat to move, the nut seat drives the drive plate to slide along the horizontal guide rail through the connecting frame and the linkage frame. Then, the traveling seat drives the movable slider to move on the slide rail, and the screw assembly drives the drive plate to slide to perform the driving operation.

[0062] When precise adjustments are required, the drive cylinder is activated to lower the locking frame. This, via the sliding seat, moves the pressure seat and brake plate downwards, pressing the brake plate against the positioning horizontal rail. This locks the drive plate and the horizontal guide rail together, preventing sliding adjustments. Simultaneously, the linkage outer rod rotates the threaded rod assembly in the opposite direction, allowing the head of the threaded rod assembly to be housed in the threaded sleeve. This releases the lock on the side shaft of the drive plate, facilitating rotational adjustment of the drive plate. When the lead screw assembly is activated to move the nut seat, the nut seat moves the lower end of the drive plate via the connecting frame and linkage frame. The drive plate can then rotate around the side shaft. By dividing the drive plate into different proportions using the side shaft, the distance the upper traveling seat moves can be calculated based on the lower end's movement distance. For example, if the side shaft is set at one of the four equal division points of the drive plate's height, the lower end's height is three times that of the upper end. When the lower end of the drive plate moves 3mm, the upper end only moves 1mm. By dividing the movement distance equally, it is easier to control the movement precision.
