[0018] In order to further understand the content, features and effects of the present application, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0019] In order to solve the above technical problems, this embodiment provides a segmented adsorption fixture for a machine tool, such as Figure 1-2As shown, it includes an adsorption platform 10 fixed on the workbench of a machine tool, an air duct component 20 installed in the adsorption platform 10, a control component 30 is provided on one side of the adsorption platform 10, and a plurality of adsorption holes 11 connected to the air duct component 20 are opened on the surface of the adsorption platform 10. The control component 30 is connected to a vacuum generating device 40. After the workpiece to be processed is placed on the adsorption platform 10, it covers the adsorption holes 11. The vacuum generating device 40 is started to work, so that the adsorption holes 11 on the adsorption platform 10 are adsorbed on the workpiece to be processed, thereby fixing the workpiece so that the machine tool can process the workpiece. The airway assembly 20 includes several groups of air paths, which are connected to the control assembly 30 through the switch controller 50 respectively. The switch controller 50 is used to individually control the conduction or closing of several groups of air paths, so that the adsorption holes 11 covered on the adsorption platform can be selected according to the size of the workpiece, and the air paths corresponding to the adsorption holes 11 are selectively opened through the switch controller 50, so that the adsorption holes 11 covered by the workpiece are adsorbed on the workpiece, and the adsorption holes 11 not covered by the workpiece do not work, thereby avoiding the adsorption holes not covered by the workpiece from working ineffectively and causing energy waste. It can be flexibly selected according to the shape and size of the workpiece, is easy to operate, and is compatible with fixing workpieces of different shapes and sizes.

[0020] Specifically, several groups of gas paths are divided into a first gas path 21, a second gas path 22 and a third gas path 23, and the first gas path 21, the second gas path 22 and the third gas path 23 are arranged in sequence along the length direction of the adsorption platform 10. The first gas path 21, the second gas path 22 and the third gas path 23 are all U-shaped, and each gas path corresponds to the adsorption holes 11 connecting different areas. When the workpiece covers the adsorption holes 11 in this area, the gas path conduction is turned on by the switch controller 50, and the vacuum generating device 40 starts working, so that the adsorption holes 11 in this area adsorb and fix the workpiece to prevent the workpiece from shifting during the processing. The adsorption holes 11 that are not covered by the workpiece do not work, avoiding inconvenience during the processing. It should be noted that the gas paths of this embodiment are divided into 3 groups as an example. In actual production, more gas path areas can be divided according to the size of the adsorption platform 10, so as to achieve a segmented adsorption function.

[0021] The vacuum generating device 40 is connected to the first pipe 32 via a vent pipe 41. The vacuum generating device 40 creates a negative pressure in the air path and the adsorption holes 11, thereby adsorbing and securing the workpiece. When the machine tool completes processing, the vacuum generating device 40 is turned off, and the workpiece can be removed after the pressure is released.

[0022] Furthermore, a number of adsorption holes 11 are equidistantly distributed on the adsorption platform 10, and a number of adsorption holes 11 are distributed in a rectangular array, and each adsorption hole 11 is connected to the first gas path 21 or the second gas path 22 or the third gas path 23. Exemplarily, the adsorption holes 11 are composed of 12 columns, the 4 columns of adsorption holes 11 on the left are connected to the first gas path 21, the 4 columns of adsorption holes 11 in the middle are connected to the second gas path 22, and the 4 columns of adsorption holes 11 on the right are connected to the third gas path 23. Exemplarily, when a small workpiece covers the 4 columns of adsorption holes 11 in the middle, the second gas path 22 is opened and the first gas path 21 and the third gas path 23 are closed by the switch controller 50. When a sink is opened in the middle of the bottom of the workpiece, the two sides of the bottom of the workpiece cover the 4 columns of adsorption holes 11 on the left and the 4 columns of adsorption holes 11 on the right, and the second gas path 22 is closed at this time. It can be flexibly selected according to the shape and size of the workpiece.

[0023] Specifically, to control the individual opening and closing of each gas path, the control assembly 30 includes a gas distributor block 31. A first pipe 32 is provided on one side of the gas distributor block 31, and a plurality of second pipes 33 are provided on the other side, connected to the first pipe 32. These second pipes 33 are connected to the first gas path 21, the second gas path 22, and the third gas path 23, respectively. A switch controller 50 is provided on each second pipe 33. By turning the switch controller 50 on or off, any of the first, second, and third gas paths 21, 22, and 23 can be selected for connection to the vacuum generating device 40.

[0024] Furthermore, in one embodiment, the switch controller 50 can be an on-off valve installed on the second pipe 33. By manually turning the on-off valve, the second pipe 33 is opened or closed, and any air path can be selected to connect to the vacuum generating device 40, thereby effectively adsorbing and fixing the workpiece. Manually turning the valve to open or close the second pipe 33 is simple and convenient.

[0025] Alternatively, in another embodiment, the switch controller 50 may be mounted on a solenoid valve on the second pipe 33. The control assembly 30 may further include a controller electrically connected to the solenoid valve. The controller controls the opening or closing of the solenoid valve to open or close the second pipe 33. This allows manual input of commands through the controller to control the closing or opening of the solenoid valve, eliminating the need for manual valve rotation, thus saving time and effort and improving work efficiency.

[0026] During workpiece machining, waste material is often generated. This material can accumulate and clog the suction holes 11, hindering the lathe's workpiece processing. To protect the suction holes 11 from this waste, a filter is embedded within each suction hole 11. During machining, waste material generated by the workpiece is intercepted by the filter, preventing it from entering the lathe. After machining is complete, the filter can be cleaned.

[0027] In summary, in one or more embodiments of the present application, the present application provides a plurality of adsorption holes on the surface of the adsorption table, the control component is connected to a vacuum generating device, and the workpiece to be processed is placed on the adsorption table and covered with the adsorption holes. The vacuum generating device is activated to work, so that the adsorption holes on the adsorption table are adsorbed on the workpiece to be processed, and the workpiece is fixed so that the machine tool can process the workpiece. The airway component includes a plurality of groups of air paths, and the plurality of groups of air paths are connected to the control component through switch controllers respectively. The switch controller is used to individually control the conduction or closing of the plurality of groups of air paths, and the position covering the adsorption holes can be selected according to the size of the workpiece, and the air paths corresponding to the adsorption holes can be selectively opened through the switch controller, so that the adsorption holes covered by the workpiece are adsorbed on the workpiece, and the adsorption holes not covered by the workpiece do not work, thereby avoiding the adsorption holes not covered by the workpiece from working ineffectively and causing energy waste. It can be flexibly selected according to the shape and size of the workpiece, is easy to operate, and is compatible with fixing workpieces of different shapes and sizes.

[0028] The above-described embodiments do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the above-described embodiments shall be included in the scope of protection of this technical solution.
