Description

Technical Field

[0001] The utility model relates to the technical field of stone processing equipment, and more specifically to a double-beam gantry drilling machine. Background Art

[0002] Stone is a commonly used material in architectural decoration, production, and daily life. The production of stone workpieces often requires processes such as cutting, carving, grinding, polishing, and drilling. During stone drilling, due to its generally high density and the presence of some hard impurities within natural stone, the continuous and irregular impact caused by these hard impurities during drilling causes significant wear on the drill bit, its mounting structure, and the drive mechanism. The characteristics of stone place high demands on the drill bit, its mounting structure, and the transmission mechanism that drives the drill bit.

[0003] To this end, the applicant has provided a Chinese utility model patent with authorization publication number CN210061611U, which describes a stone drilling device comprising a frame, a lifting base, and a drilling mechanism. The frame houses the stone workpiece being processed, the lifting base being mounted on the frame, and the drilling mechanism being mounted on the lifting base. The lifting base is positioned above the stone workpiece, capable of reciprocating upward and downward movement toward the workpiece. The device utilizes a gantry-type single-beam structure to achieve three-axis movement for drilling holes in stone. However, because the drilling mechanism is mounted on the sidewall of one side (the front side) of the beam, the drilling mechanism's center of gravity shifts forward during actual production use, resulting in a certain offset in the hole diameter when drilling vertically. In addition, when drilling holes in stone, the drilling mechanism will vibrate back and forth on the horizontal plane under the action of mutual forces. The drilling mechanism and the side wall of the beam adopt a rigid structure such as simple welding or bolt locking, and only one side of the drilling mechanism can withstand force. The structural stability of the equipment is poor. The vibration during operation not only affects the quality of drilling, but also brings additional load to the drilling mechanism, the three-axis moving mechanism of the gantry, etc. Utility Model Content

[0024] The specific implementation of the embodiment of the present utility model is described below with reference to the accompanying drawings.

[0025] Reference Figures 1 to 3 A double-beam gantry drilling machine includes two side frames 10 on the left and right, a crossbeam 20, a transverse movement seat 30, a lifting seat 40 and a drilling mechanism 50. The crossbeam 20 can be movably mounted between the two side frames 10 along the Y-axis direction of the side frame 10, the transverse movement seat 30 can be movably assembled on the crossbeam 20 along the X-axis direction of the crossbeam 20, the lifting seat 40 can be lifted and lowered on the transverse movement seat 30 along the Z-axis direction of the transverse movement seat 30, and the drilling mechanism 50 is arranged on the lifting seat 40. The crossbeam 20 is a double-beam structure integrally connected by two beam bodies 22. The two beam bodies 22 are arranged in parallel and spaced apart. The transverse movement seat 30 is arranged between the two beam bodies 22, and the left and right sides of the transverse movement seat 30 are respectively provided with X-axis supporting cylinders 60 for supporting and fixing the two beam bodies 22.

[0026] Reference Figure 1 and Figure 4 Specifically, the crossbeam 20 includes two left and right longitudinal shifting seats 21, which are movably mounted on the two side frames 10. The two ends of the two beam bodies 22 are fixedly connected to the two longitudinal shifting seats 21, and the longitudinal shifting seats 21 and the beam bodies 22 are provided with an X-axis moving mechanism for driving the transverse shifting seat 30 to move.

[0027] Reference Figures 1 to 4 The X-axis moving mechanism includes at least two X-axis slide rails 23, an X-axis screw guide rail 24 and an X-axis servo motor 25 for driving the X-axis screw guide rails 24 to operate. In this embodiment, there are four X-axis slide rails 23, and an X-axis slide rail 23 is laid on the upper and lower surfaces of the two beams 22 respectively. The transverse shift seat 30 is an I-shaped frame structure, and the inner sides of the I-shaped ends of the transverse shift seat 30 are movably assembled on the X-axis slide rails 23 respectively. The two ends of the X-axis screw guide rail 24 are respectively installed on the two longitudinal shift seats 21, and the slide seat of the X-axis screw guide rail 24 is fixedly connected to the transverse shift seat 30 for driving the transverse shift seat 30 to move. The X-axis servo motor 25 is installed on the longitudinal shift seat 21. The X-axis servo motor 25 is connected to the X-axis screw guide rail 24 through a speed change gear box (not shown in the figure) for driving its operation.

[0028] Reference Figure 1 、 Figure 3 and Figure 4 At least two X-axis supporting cylinders 60 are provided, each fixedly mounted on the left and right sides of the traversing base 30. The output shafts of the two X-axis supporting cylinders 60 support the side walls of the two beams 22, respectively. Rubber supporting pads are provided on the output shafts of the X-axis supporting cylinders 60. In the present invention, four X-axis supporting cylinders 60 can also be provided, symmetrically arranged in pairs. For example, two X-axis supporting cylinders 60 are provided on the left side of the traversing base 30 to support the two beams 22, respectively, and two X-axis supporting cylinders 60 are also provided on the right side of the traversing base 30 to support the two beams 22, respectively.

[0029] Reference Figures 1 to 5 The side frames 10 are provided with a Y-axis moving mechanism for driving the movement of the crossbeam 20. The Y-axis moving mechanism includes a Y-axis slide rail 11 and a Y-axis screw guide rail 12 laid on the side frames 10. The longitudinal movement seat 21 is slidably mounted on the Y-axis slide rail 11 and fixedly connected to the slide seat of the Y-axis screw guide rail 12. The Y-axis moving mechanism also includes a Y-axis servo motor 13 for driving the operation of the Y-axis screw guide rail 12. In this embodiment, since there are two side frames 10, there are also two sets of Y-axis moving mechanisms, but the Y-axis servo motor 13 is a bidirectional servo motor. The Y-axis servo motor 13 is arranged between the two side frames 10. The two output shafts of the Y-axis servo motor 13 are respectively connected to the two Y-axis screw guide rails 12 through helical gear transmission.

[0030] The longitudinal shift seat 21 is provided with a Y-axis holding cylinder 70 for holding the fixed side frame 10, and a rubber holding pad is provided on the output shaft of the Y-axis holding cylinder 70. In this embodiment, the Y-axis holding cylinder 70 is preferably four, and two are provided on one longitudinal shift seat 21.

[0031] Reference Figure 2 and Figure 5The lifting base 40 is an integrated structure consisting of a lifting top base 41, a lifting base 42, and guide columns 43. Four guide columns 43 are preferably provided, extending through the four corners of the traversing base 30. Sliding sleeves 44 are slidably mounted on the guide columns 43, and the sliding sleeves 44 are fixedly connected to the traversing base 30.

The slides of the two Z-axis screw guides 45 are fixedly connected to the traversing base 30. Since the traverse seat 30 is limited in the Z-axis direction, when the Z-axis screw guide rail 45 operates, the entire lifting seat 40 will move up and down in the Z-axis direction of the traverse seat 30. The drilling mechanism 50 of the present invention can adopt the existing stone drilling mechanism 50, which will not be further described here.

[0032] Reference Figures 1 to 5 When the present invention is in operation, the Y-axis moving mechanism drives the crossbeam 20 to move on the Y-axis of the side frame 10. When it moves to the specified position, the Y-axis servo motor 13 stops working. At the same time, the output shafts of the four Y-axis supporting cylinders 70 extend out and support the side frame 10, thereby completely fixing the crossbeam 20. Subsequently, the transverse shift seat 30 is driven to move on the X-axis of the crossbeam 20 by the X-axis moving mechanism. When it moves to the specified position, the X-axis servo motor 25 stops working. At the same time, the output shafts of at least two X-axis supporting cylinders 60 (or four X-axis supporting cylinders 60) extend out and support the side walls of the two beam bodies 22, thereby completely fixing the transverse shift seat 30. Finally, the Z-axis moving mechanism drives the lifting seat 40, thereby driving the drilling mechanism 50 to move up and down to complete the drilling work of the stone.

[0033] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
