Description

Technical Field

[0001] The present application belongs to the field of drilling and milling machines, and in particular to a drilling and milling machine with upper and lower double drill packages. Background Art

[0002] The drilling and milling machine is a woodworking machine that can achieve high-speed and efficient wood processing through the control of a precise CNC system. It can not only perform basic operations such as drilling and milling, but also complex engraving, cutting and other processes to meet various needs in wood processing. The drilling and milling machine mostly adopts the design of a drill bag on the upper and lower sides, so that it can process the upper and lower surfaces of the board at the same time to improve processing efficiency. However, when processing two holes with a certain distance on the surface of the board, it is necessary to move the upper drill bag or the lower drill bag to the upper side / lower side of one of the hole positions. In this process, the drill bag needs to be accurately positioned. After drilling the first hole, the upper drill bag or the lower drill bag will move to the upper side / lower side of another hole position and position it again. Two moves are required. The additional operation not only increases the processing time, but may also introduce errors and reduce the processing accuracy. It can be seen that the existing technology needs to be further improved and improved. Utility Model Content

[0003] The utility model provides a drilling and milling machine with upper and lower double drill bags, which is used to solve the problem that a drilling and milling machine with one drill bag each needs to move twice and position twice when processing two holes with a horizontal distance in a plate, resulting in low processing efficiency and low processing accuracy.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A drilling and milling machine with upper and lower double drill bags, comprising a portal frame, a transport mechanism arranged between two vertical beams of the portal frame, and a drill bag arranged on a cross beam of the portal frame, characterized in that the cross beam comprises a first cross beam and a second cross beam which are arranged vertically and in parallel, the first cross beam is slidably provided with two first Y-axis slides, the second cross beam is slidably provided with two second Y-axis slides, the first Y-axis slide is installed with an upper drill bag, the second Y-axis slide is installed with a lower drill bag, the first Y-axis slide is connected to a first drive motor, the second Y-axis slide is connected to a second drive motor, the output shafts of the first drive motor and the second drive motor are both connected to drive teeth, the first cross beam and the second cross beam are both provided with racks, the drive teeth are matched and connected with the racks, the first drive motor and the second drive motor are connected to a controller by wires, a distance sensor is provided on the side of the first Y-axis slide / the second Y-axis slide, and the controller controls the drill bag to move independently according to the hole spacing between the holes to be processed in the plate to achieve precise positioning.

[0006] The drilling and milling machine with upper and lower double drill bags of the present application is designed with an independent drive system. The first drive motor and the second drive motor respectively control the position of the upper drill bag and the lower drill bag, so that each drill bag can be independently and accurately moved to the desired position. The distance between the two drill bag spindles on the first beam or the second beam is measured and adjusted by a distance sensor to ensure that they match the spacing of the holes on the plate, which greatly improves the accuracy of processing. After adjusting the position of the drill bag, the control system can simultaneously control the two drill bags for synchronous processing, further improving the processing efficiency. The operator only needs to input the spacing of the holes in the controller, and the machine can automatically complete the subsequent adjustment and processing work, simplifying the operation process, reducing the skill requirements for the operator, reducing the need for repeated positioning and moving of the drill bag, reducing unnecessary movement and positioning time, and can significantly reduce the errors introduced during the processing and improve the processing accuracy.

[0007] In a preferred implementation, the drill kit includes a rotary motor for driving the drill bit to rotate and a telescopic cylinder for driving the drill bit to extend and retract, and the rotary motor and the telescopic cylinder are arranged in parallel along a direction perpendicular to the crossbeam.

[0008] By arranging the rotating motor for driving the drill bit to rotate and the telescopic cylinder for driving the drill bit to telescope in parallel along the direction perpendicular to the crossbeam, the width of the crossbeam can be reduced and a wider adjustment range of the distance between the two drill bits can be allowed.

[0009] In a preferred implementation, the drill package is disposed on a Z-axis slide, and the Z-axis slide is slidably disposed on the first Y-axis slide / the second Y-axis slide.

[0010] In a preferred implementation, one side of the first Y-axis skateboard / the second Y-axis skateboard is provided with a first slider arranged along the direction of the crossbeam, the first crossbeam / the second crossbeam is provided with a first slide rail, and the first slider and the first slide rail are cooperatively connected; the other side of the first Y-axis skateboard / the second Y-axis skateboard is provided with a second slide rail arranged along the Z-axis direction, the Z-axis skateboard is provided with a second slider, and the second slider and the second slide rail are cooperatively connected.

[0011] In a preferred implementation, the Z-axis slide is connected to a lifting mechanism, and the lifting mechanism wires are connected to a controller to achieve drilling package lifting.

[0012] In a preferred implementation, the lifting mechanism includes a lifting motor, a lead screw, and a connecting piece capable of linear movement on the lead screw, and the connecting piece is connected to the Z-axis slide.

[0013] In a preferred implementation, the first drive motor is installed on the side of the first Y-axis slide away from the upper drill package through an L-shaped mounting plate, and the second drive motor is installed on the same side of the second Y-axis slide through an ear plate integral with the second Y-axis slide.

[0014] For the upper drill package, due to the relatively large space, an L-shaped mounting plate is used to install the first drive motor on the side of the slide away from the drill package, which can avoid interference between the motor and the drill package and ensure the normal operation of the drill package. Considering that the space of the lower drill package is smaller and it is located at the bottom of the equipment, its available space is often limited. By directly combining the second drive motor with the ear plate of the second Y-axis slide, additional installation space can be saved, making the layout of the lower drill package area more compact.

[0015] In a preferred implementation, the transport mechanism includes a front-section transport mechanism and a rear-section transport mechanism, there is a gap between the front-section transport mechanism and the rear-section transport mechanism to accommodate two groups of drill bags, a gantry frame is arranged at the end of the rear-section transport mechanism, a pressing beam frame is provided at the tail end of the front-section transport mechanism, and a pressing roller that can be raised and lowered is installed on the pressing beam frame.

[0016] In a preferred implementation, a lifting pressing roller is provided on the lower bottom surface of the first crossbeam. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] In the description of the present invention, it is necessary to understand that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the present invention, unless otherwise clearly specified and limited, a first feature being "upper" or "lower" than a second feature may be the first and second features directly contacting, or the first and second features indirectly contacting through an intermediate medium.

[0025] In the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are connected to form a whole only through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0026] In the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0027] The utility model is described below in conjunction with the accompanying drawings.

[0028] The specific plans adopted are:

[0029] like Figure 1-3As shown, the utility model provides a drilling and milling machine with upper and lower double drill bags, including a door-type frame, a transport mechanism 2 arranged between two vertical beams of the door-type frame, and a drill bag 3 arranged on the cross beam of the door-type frame, the cross beam includes a first cross beam 10 and a second cross beam 11 arranged vertically and in parallel, the first cross beam 10 is slidably provided with two first Y-axis slide plates 12, the second cross beam 11 is slidably provided with two second Y-axis slide plates 14, the first Y-axis slide plate 12 is installed with an upper drill bag, the second Y-axis slide plate 14 is installed with a lower drill bag, the first Y-axis slide plate 12 is connected to the first drive The first Y-axis slide 12 / the second Y-axis slide 14 is connected to the second drive motor 15, the output shafts of the first drive motor 13 and the second drive motor 15 are connected to the drive teeth, the first crossbeam 10 and the second crossbeam 11 are both provided with a rack 100, the drive teeth are matched and connected with the rack 100, the first drive motor 13 and the second drive motor 15 are connected to the controller by wires, and a distance sensor is provided on the side of the first Y-axis slide 12 / the second Y-axis slide 14. The controller controls the drill package to move independently according to the hole spacing between the holes to be processed in the plate to achieve precise positioning.

[0030] The drilling and milling machine with upper and lower double drill bags of the present application is designed with an independent driving system. The first driving motor 13 and the second driving motor 15 respectively control the positions of the upper drill bag and the lower drill bag, so that each drill bag can be independently and accurately moved to the desired position. The distance between the two drill bag spindles on the first beam 10 or the second beam 11 is measured and converted and adjusted by the distance sensor of the Y-axis slide. The distance sensor is not shown and can be set on the opposite edges of the two Y-axis slides or embedded in the inner sides of the edges of the two Y-axis slides. Since the distance between the edge of the Y-axis slide and the spindle is fixed, a simple conversion can be performed, that is, when the distance between the edges of the two Y-axis slides is d1, the center distance between the two spindles is d2, which can be understood by people skilled in the art.

[0031] Specifically, during the processing, for example, to process two holes on the upper surface of a plate, the operator inputs the specific hole distance between the two holes to be processed on the plate in the controller. The controller drives the first drive motor 13 to work according to the input hole distance, and cooperates with the rack 100 on the first crossbeam 10 through the driving teeth, so that the two first Y-axis slides 12 (with the upper drill packages installed) slide on the crossbeam until the spindle spacing of the two upper drill packages is equal to the input hole distance. During this process, the distance sensor monitors and feedbacks the position of the slide in real time to ensure the accuracy of the distance adjustment. After the distance adjustment is completed, the control system will simultaneously control the two upper drill packages to perform synchronous actions and accurately move them to the corresponding hole positions on the plate. Since the two drill packages move synchronously, the relative position between them always remains unchanged, ensuring the accuracy of hole positioning. Once the positioning of the two upper drill packages is completed, the control system will start the drilling program and process the two holes on the plate at the same time. Since the two drill packages work synchronously, the processing process will be very fast and efficient. Through one-time distance adjustment and synchronous hole positioning, the need for repeated positioning and movement of the drill package is avoided, thereby reducing processing time and potential errors. At the same time, the design of the upper and lower double drill packages also enables the machine to process the upper and lower surfaces of the plate at the same time, further enhancing the flexibility and adaptability of the equipment.

[0032] As a preferred embodiment of the present application, see Figure 3 The drill package includes a rotating motor 30 for driving a drill bit 32 to rotate and a telescopic cylinder 31 for driving the drill bit 32 to extend and retract. The rotating motor 30 and the telescopic cylinder 31 are arranged side by side in a direction perpendicular to the crossbeam. By arranging the rotating motor 30 for driving the drill bit 32 to rotate and the telescopic cylinder 31 for driving the drill bit 32 to extend and retract in parallel in a direction perpendicular to the crossbeam, the width of the crossbeam can be reduced and a wider adjustment range of the distance between the two drill bits 32 can be allowed.

[0033] To move the drill package along the Z axis, see Figure 2 and Figure 3 The drill package is arranged on the Z-axis slide 16, and the Z-axis slide 16 is slidably arranged on the first Y-axis slide 12 / the second Y-axis slide 14. The Z-axis slide 16 is connected to the lifting mechanism 6, and the lifting mechanism 6 is connected to the controller by wires to realize the lifting of the drill package.

[0034] Specifically, one side of the first Y-axis skateboard 12 / the second Y-axis skateboard 14 is provided with a first slider 50 arranged along the direction of the crossbeam, the first crossbeam 10 / the second crossbeam 11 is provided with a first slide rail 51, and the first slider 50 and the first slide rail 51 are cooperatively connected; the other side of the first Y-axis skateboard 12 / the second Y-axis skateboard 14 is provided with a second slide rail 52 arranged along the Z-axis direction, the Z-axis skateboard 16 is provided with a second slider 53, and the second slider 53 and the second slide rail 52 are cooperatively connected.

[0035] See also Figure 3The lifting mechanism 6 includes a lifting motor 60, a lead screw 61 and a connecting part that can move linearly on the lead screw 61. The connecting part is connected to the Z-axis slide 16. The lifting motor 60 serves as a power source. It converts electrical energy into mechanical energy to drive the rotation of the lead screw 61. The thread on the lead screw 61 cooperates with the thread in the connecting part. When the lead screw 61 rotates, the connecting part will move linearly along the axial direction of the lead screw 61. The connecting part is connected to the Z-axis slide 16. Therefore, the movement of the connecting part will drive the Z-axis slide 16 and the drill bag to rise and fall. By controlling the forward and reverse rotation of the lifting motor 60, the rise and fall of the drill bag can be realized. The lifting mechanisms 6 of the two drill bags can work synchronously to ensure that the relative positions of the two drill bags remain unchanged during the lifting process, thereby improving the processing accuracy.

[0036] In addition, for the upper drill package, due to the relatively large space, the first drive motor 13 is installed on the side of the skateboard away from the drill package using an L-shaped mounting plate 17, which can avoid interference between the motor and the drill package and ensure the normal operation of the drill package. Considering that the space of the lower drill package is smaller and it is located at the bottom of the equipment, its available space is often limited. By directly combining the second drive motor 15 with the ear plate of the second Y-axis skateboard 14, additional installation space can be saved, making the layout of the lower drill package area more compact.

[0037] See also Figure 1 The transport mechanism 2 includes a front transport mechanism and a rear transport mechanism. There is a gap between the front transport mechanism and the rear transport mechanism to accommodate two groups of lower drill bags. The door-type frame is arranged at the end of the rear transport mechanism. A pressing beam frame 4 is provided at the tail end of the front transport mechanism 2. The pressing beam frame 4 is installed with a pressing roller 40 that can be lifted and lowered. At the same time, a lifting pressing roller 40 is arranged on the lower bottom surface of the first cross beam 10. Through the design of the front transport mechanism 2 and the rear transport mechanism 2, the plate can maintain stable transmission during the entire processing process. When the plate is transported to the designed position, it is pressed by the pressing roller 40 from top to bottom. This double pressing mechanism ensures that the plate will not move or deviate during the processing of the upper and lower double drill bags, thereby greatly improving the processing accuracy.

[0038] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0039] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
