It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Examples, such as Figures 1-8 As shown, this utility model provides a multi-faceted thermal drilling and tapping device, including a frame 1. The frame 1 includes a bottom support and a gantry frame, with the gantry frame spanning both sides of the bottom support. In this embodiment, the spanning direction of the gantry frame is perpendicular to the moving direction of the moving platform assembly 3, but it can also be set to be parallel or other angles as needed to adapt to specific processing scenarios. Based on this, the frame 1 provided by this utility model is equipped with at least one multi-faceted tapping mechanism 2. The multi-faceted tapping mechanism 2 includes a workpiece clamping device 7 for fixing and positioning a workpiece 6. The power input side of the workpiece clamping device 7 is equipped with the moving platform assembly 3, which drives it to move linearly reciprocatingly. The frame 1 is equipped with at least two drilling devices, and the processing areas on the workpiece 6 are not coplanar. A controller 8 is provided on the control side of the moving platform assembly 3, the workpiece clamping device 7, and the drilling devices. The workpiece clamping device 7 clamps and positions the workpiece 6, such as a square tube, used in children's furniture. The moving platform assembly 3 adjusts the front and rear positions of the workpiece clamping device 7. The multi-faceted tapping mechanism 2 processes at least two sides of the workpiece 6, including the sides and top, using drilling devices located in different processing directions. Furthermore, having two multi-faceted tapping mechanisms 2 allows for simultaneous drilling and tapping operations. This eliminates the need for frequent repositioning of the workpiece 6 while ensuring the quality of drilling and tapping, effectively improving workshop efficiency and production capacity.

[0030] Furthermore, the mobile platform component 3 provided by this utility model includes a support plate 31, which serves as a support base for part of the drilling device and the workpiece clamping device 7. Under the drive of the power mechanism of the mobile platform component 3, the drilling device and the workpiece clamping device 7 can be adjusted back and forth.

[0031] In order to achieve automatic clamping and fixing of workpiece 6, the workpiece clamping device 7 provided by this utility model is arranged along the moving direction of the support plate 31 in the length direction, which facilitates the processing of workpiece 6; at the same time, the workpiece clamping device 7 is arranged on the support plate 31 near the middle position to improve the support balance of the support plate 31 and the smoothness of its movement driven by the driving force.

[0032] Regarding the workpiece clamping device 7, it specifically includes a support plate 74 mounted on the support plate 31 via a support member 77. One end of the support plate 74 is provided with an end face fixing baffle 73, and the other end of the support plate 74 is provided with a movable end face moving baffle 75. One side of the workpiece 6 is provided with a side fixing baffle 72, which is fixedly mounted on one side of the support plate 74 or fixedly mounted on the support plate 31 near the support plate 74. The other side of the workpiece 6 is provided with a side moving baffle 71. The end face moving baffle 75 and the side moving baffle 71 are driven by two telescopic devices 76 respectively. The support member 77 is made of simple sheet metal and serves to support the workpiece clamping device 7, providing multiple connecting holes as a connection base. Bolts driven into these holes indirectly establish a connection between the workpiece clamping device 7 and the support plate 31. The end face fixed baffle 73 faces the end face movable baffle 75, and the side face fixed baffle 72 faces the side face movable baffle 71. The telescopic device 76, used to control the end face movable baffle 75, clamps both ends of the workpiece 6 by changing the distance between the end face movable baffle 75 and the end face fixed baffle 73. The telescopic device 76, used to control the side face movable baffle 71, clamps both sides of the workpiece 6 by changing the distance between the side face movable baffle 71 and the side face fixed baffle 72. The telescopic device 76 can be an electric telescopic rod or a similar structure, or it can be a cylinder or hydraulic cylinder, or other structures capable of telescopic movement. It can be directly controlled by the controller 8 for telescopic movement as needed, or it can be controlled by the controller 8 via a solenoid valve.

[0033] To effectively achieve thermal drilling and tapping operations, the drilling device provided by this utility model is either a first drilling device 4 or a second drilling device 5. This embodiment provides four drilling devices, two of which are first drilling devices 4, and the other two are second drilling devices 5.

[0034] The first drilling device 4 is mounted on the moving platform assembly 3, specifically on the support plate 31, and symmetrically distributed on both sides of the workpiece clamping device 7, for machining the two sides of the workpiece 6. The first drilling device 4 includes a first drilling unit 41 for drilling or tapping the sides of the workpiece 6. A three-dimensional CNC platform 42 is mounted on the drive side of the first drilling unit 41, and the three-dimensional CNC platform 42 is connected to the support plate 31. The three-dimensional CNC platform 42 is a mature existing technology, mainly used to control the spindle of the first drilling unit 41 to move in the X, Y, and Z axes. The first drilling unit 41 can optionally be equipped with drill bits or taps as drilling or tapping tools as needed.

[0035] The second drilling device 5 is mounted on the frame 1, specifically on the gantry section of the frame 1, near the workpiece 6. Two second drilling devices 5 are symmetrically arranged on both sides of the gantry, facilitating machining of specific locations. The second drilling device 5 includes a second drilling unit 51 for drilling or tapping the upper surface of the workpiece 6. A cross-shaped CNC platform 52 is mounted on the drive side of the second drilling unit 51. The cross-shaped CNC platform 52 is a mature existing technology, primarily used to control the spindle of the second drilling unit 51 to move along the X and Z axes. The second drilling unit 51 can optionally be equipped with drill bits or taps as drilling or tapping tools.

[0036] To improve the machining efficiency of this equipment, the multi-face tapping mechanism 2 provided by this utility model is configured in two sets. One set of multi-face tapping mechanism 2 is used for drilling holes in the workpiece 6, and the other set of multi-face tapping mechanism 2 is used for tapping the drilled workpiece 6. The two sets of multi-face tapping mechanisms 2 share a set of frame 1 and a set of moving platform assembly 3, which can obtain reasonable machining capacity while ensuring the utilization of equipment space, and is conducive to improving the production and processing efficiency of the workshop.

[0037] Regarding the controller 8, the controller 8 provided by this utility model is a PLC, but it can also be set to other types of controller 8 as needed. Furthermore, the controller 8 is connected to two switches, which are used to control the start and stop actions of the corresponding multi-faceted tapping mechanism 2 at appropriate times. This facilitates flexible operation for picking up and placing the workpiece 6, and ensures the safety of picking up and placing the workpiece 6.

[0038] To improve the performance of the mobile platform assembly 3 in adjusting the workpiece clamping device 7 and the first drilling device 4, the mobile platform assembly 3 provided by this utility model includes a slide rail 33 and a slider 32 that cooperate with the support plate 31. The slider 32 is set at the bottom of the support plate, and the slide rail 33 is set on the bottom support of the frame 1. A rack 34 is set on the bottom support of the frame 1. The length direction of the rack 34 is set along the moving direction of the support plate 31. A gear 35 is set on the transmission side of the rack 34 and meshes with it. A motor 36 is set at the power input end of the gear 35. The motor 36 drives the gear 35 and the rack 34 to complete the transmission and drive the support plate 31 and all the structures installed on the support plate 31 to perform linear reciprocating motion. The motor 36 is set on the support plate 31 and can move synchronously with the support plate 31.

[0039] More specifically, regarding the processing procedure of this equipment, firstly, the workpiece 6 is placed on the support plate 74 of the multi-face tapping mechanism 2 responsible for drilling, and it is in contact with the end face fixed baffle 73 and the side fixed baffle 72. Then, the multi-face tapping mechanism 2 is started by the foot switch. The controller 8 controls the telescopic component to move, thereby driving the side moving baffle 71 and the end face moving baffle 75 to clamp and fix the workpiece 6. Then, the controller 8 controls the drilling device to perform drilling operations. After the drilling operation is completed, the foot switch is operated again to stop the multi-face tapping mechanism 2. At the same time, the controller 8 controls the drilling device to reset, and the end face moving baffle 75 and the side moving baffle 71 are also reset. The drilled workpiece 6 is replaced, and the above actions are repeated by operating the foot switch again.

[0040] Then, the drilled workpiece 6 is placed on the support plate 74 of the multi-face tapping mechanism 2 for tapping operations, and it is attached to the end face fixed baffle 73 and the side fixed baffle 72. Then, the multi-face tapping mechanism 2 is started by the foot switch. The controller 8 controls the telescopic component to move, thereby driving the side moving baffle 71 and the end face moving baffle 75 to clamp and fix the workpiece 6. Then, the controller 8 controls the drilling device to perform tapping operations. After the tapping operation is completed, the foot switch is operated again to stop the multi-face tapping mechanism 2. At the same time, the controller 8 controls the drilling device to reset, and the end face moving baffle 75 and the side moving baffle 71 are also reset. The drilled workpiece 6 is replaced, and the above actions are repeated by operating the foot switch again.

[0041] This invention, by setting up a multi-faceted tapping mechanism 2, can perform machining operations on at least two sides of the workpiece 6. By setting up two multi-faceted tapping mechanisms 2, drilling and tapping operations can be performed simultaneously, effectively improving work efficiency and productivity. The second drilling device 5 adopts a stable installation method, which can improve structural stability and machining quality. This invention solves the problem that in the prior art, traditional machine tools are commonly used for machining, which require flipping the workpiece 6 during the machining process to process the surfaces to be machined in sequence, resulting in low efficiency.
