[0002] Milling is a machining method that uses a milling cutter as a cutting tool to process the surface of an object. Milling machines include horizontal milling machines, vertical milling machines, gantry milling machines, profile milling machines, universal milling machines, and lever milling machines. For example, the precision and easy-to-maintain CNC milling machine disclosed in application number CN202021874796.0 includes a work operation panel, a top of the milling machine, a main body of the milling machine, a work platform, and a base of the milling machine. The milling machine worktable disclosed in application number CN202121392799.5 includes a milling machine, with a milling machine worktable installed on the inner side of the middle of the milling machine. The milling machine worktable has a T-slot inside, and a fixture is provided on the top surface of the middle of the milling machine worktable. Locking components are provided between the two sides of the bottom of the fixture and the T-slot inside the milling machine worktable.

[0003] Existing milling machines have diverse structures and functions, and can process various products according to production needs. However, they are only suitable for milling workpieces with relatively thick thickness. They lack reliable clamping and precise positioning technology for thin plate workpieces with poor rigidity. They are unable to effectively deal with situations such as bending, vibration, or even breakage of thin plate workpieces during high-speed milling, which can easily lead to problems such as affecting the machining accuracy and yield of the workpieces. Utility Model Content

[0004] The purpose of this invention is to overcome the technical problems in the prior art where thin plate workpieces are bent, vibrated or even broken due to the lack of reliable clamping and precise positioning during milling. It provides a platform adsorption assembly for stable adsorption and precise positioning of the workpiece during milling, so as to ensure the machining accuracy and yield of the workpiece.

[0005] To solve the above-mentioned technical problems, this utility model provides a platform adsorption assembly, including a worktable, on which a milling cutter and a first driving mechanism for driving the milling cutter to mill the workpiece are arranged. An adsorption panel is arranged below the milling cutter, and a second driving mechanism for driving the adsorption panel to move longitudinally is arranged. The adsorption panel is arranged in a horizontal direction and has a plurality of ventilation holes. The upper surface of the adsorption panel is used to support and adsorb the workpiece. The lower surface of the adsorption panel is provided with a suction hood. The suction hood is connected to a suction fan through a suction pipe. A base is arranged on the worktable. The second driving mechanism includes a floating cylinder arranged on the base and driven in a longitudinal direction. The output shaft of the floating cylinder is drivenly connected to the adsorption panel through a spherical bearing.

[0006] As a further improvement of this utility model, the aforementioned ventilation holes are all configured as elongated strips, arranged in parallel on the adsorption panel.

[0007] As a further improvement of this utility model, the aforementioned ventilation holes are all round holes and are arranged evenly on the adsorption panel.

[0008] As a further improvement of this utility model, a slide rail is provided on the base along the driving direction of the floating cylinder, and a slider is slidably arranged on the slide rail, the slider being connected to the adsorption panel.

[0009] As a further improvement of this utility model, a connecting plate is provided between the slider and the adsorption panel, and the connecting plate is fixedly connected to the slider and the adsorption panel respectively.

[0010] As a further improvement of this utility model, the aforementioned spherical bearing is mounted on the connecting plate.

[0011] As a further improvement of this utility model, the base is provided with an adjustment component for adjusting the horizontal height of the adsorption panel. The adjustment component includes an adjustment seat fixedly connected to the base and an adjustment element that is movably engaged with the adjustment seat.

[0012] As a further improvement of this utility model, the end of the above-mentioned adjusting member is provided with a contact surface that contacts the connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model sets up an adsorption panel and connects the lower surface of the adsorption panel, the interior of the suction hood, and the interior of the suction pipe to form a sealed negative pressure cavity. The air between the workpiece and the adsorption panel is quickly sucked away by the suction fan through the negative pressure cavity. The pressure difference formed on the upper and lower surfaces of the workpiece makes the workpiece flat and stable pressed on the adsorption panel, ensuring the precise positioning of the workpiece, so as to facilitate the milling process of the milling cutter and ensure the machining accuracy and yield of the workpiece.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Rather, the present utility model covers any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of the present utility model as defined in the claims.

[0023] Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0024] Example 1: As Figures 1 to 6 As shown, the platform adsorption assembly is mainly used to keep thin sheet metal workpieces straight during milling by using airflow to prevent bending, vibration, or even breakage under the high-speed cutting and vibration of the milling cutter, thus ensuring the machining accuracy and yield of thin sheet metal workpieces. The worktable is equipped with milling cutters and a first drive mechanism to drive the milling cutters to mill the workpiece.

[0025] An adsorption panel 1 is positioned below the milling cutter. The adsorption panel 1 is horizontally oriented to facilitate the support and adsorption of the workpiece on its upper surface. Several ventilation holes 3 are provided on the adsorption panel 1. In this embodiment, the ventilation holes 3 are all elongated and arranged parallel to each other on the adsorption panel 1. On the one hand, the elongated ventilation holes 3 provide a smoother channel for airflow, improving adsorption efficiency; on the other hand, the waste chips generated during milling are less likely to clog the elongated ventilation holes 3, ensuring the long-term stability of the adsorption panel 1 and reducing the frequency of downtime for cleaning the platform adsorption assembly. A suction hood 4 is provided on the lower surface of the adsorption panel 1. The suction hood 4 is connected to a suction fan through a suction pipe. The lower surface of the adsorption panel 1, the interior of the suction hood 4, and the interior of the suction pipe are connected to form a closed negative pressure cavity. When the suction fan is started, the air between the workpiece and the adsorption panel 1 is quickly sucked away through the negative pressure cavity. The pressure difference formed on the upper and lower surfaces of the workpiece makes the workpiece flat and stable pressed on the adsorption panel 1, so as to facilitate the milling process of the milling cutter.

[0026] A base 5 is provided on the worktable. The second drive mechanism 2, which drives the adsorption panel 1 to move longitudinally, includes a floating cylinder 6 mounted on the base 5 and driven in the longitudinal direction. The output shaft of the floating cylinder 6 is connected to the adsorption panel 1 via a spherical bearing 7. The floating cylinder 6 provides a flexible driving force to the adsorption panel 1, allowing the adsorption panel 1 to move the workpiece upward to the designated processing position while avoiding rigid impact between the milling cutter and the workpiece. The spherical bearing 7 automatically compensates for minor deviations between the axis of the floating cylinder 6 and the movement trajectory of the adsorption panel 1, and ensures that the adsorption panel 1 remains horizontal during milling, thereby ensuring that the workpiece is in a flat, level state to facilitate milling.

[0027] To ensure the vertical movement accuracy of the adsorption panel 1, a slide rail 8 is provided on the base 5 along the driving direction of the floating cylinder 6. A slider 9 is slidably arranged on the slide rail 8. The slider 9 is connected to the adsorption panel 1. Specifically, in this embodiment, a connecting plate 10 is provided between the slider 9 and the adsorption panel 1, and the connecting plate 10 is fixedly connected to the slider 9 and the adsorption panel 1 respectively. The spherical bearing 7 is also installed on the connecting plate 10.

[0028] The base 5 is equipped with an adjustment component for adjusting the horizontal height of the adsorption panel 1. The adjustment component includes an adjustment seat 11 fixedly connected to the base 5 and an adjustment member 12 movably engaged with the adjustment seat 11. The end of the adjustment member 12 is provided with a contact surface 13 that contacts the connecting plate 10. Specifically, in this embodiment, the adjustment member 12 is configured as a screw that engages with a threaded hole on the adjustment seat 11. During the debugging of the platform adsorption assembly, the horizontal height of the connecting plate 10 can be adjusted by rotating the adjustment member 12 to change its extension length, thereby adjusting the initial horizontal height of the adsorption panel 1. After debugging is completed, when the floating cylinder 6 is activated, the contact surface 13 at the end of the adjustment member 12 separates from the connecting plate 10, and the connecting plate 10 drives the adsorption panel 1 to move upward from the adjusted height to the cutting height.

[0029] Example 2: Figure 7 As shown, this embodiment is largely the same as embodiment 1, except that in this embodiment, all ventilation holes 3 are round holes, arranged evenly on the adsorption panel 1. The round ventilation holes 3 are simple to process and can achieve the densest and most uniform distribution on the adsorption panel 1, thereby ensuring the uniformity of adsorption force and avoiding bending deformation of thin plate workpieces during milling due to insufficient local adsorption force, thus ensuring the processing quality of the workpiece.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. For those skilled in the art, several modifications and improvements can be made without departing from the present utility model, and these should also be considered to fall within the protection scope of the present utility model.
