[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-5The present invention provides the following technical solution: a vacuum chuck for a CNC lathe, comprising a CNC lathe body 1, a chuck base 2 on the top of the CNC lathe body 1, a suction cover 4 on the top of the suction base 2, a suction hole 5 on the top surface of the suction cover 4, a workpiece clamp 6 on the top surface of the suction cover 4, a cleaning component 3 on one side of the suction base 2, and a positioning component 7 on the side of the suction base 2 away from the cleaning component 3.

[0026] Specifically, the cleaning component 3 includes a cleaning housing 31, an inclined block 32, a magnetic block 33, a filter component 34, a water outlet 35, a pipe interface 36, and a sealing ring 37. The cleaning housing 31 is installed on one side of the suction cup base 2. An inclined block 32 is installed inside the cleaning housing 31. A magnetic block 33 is installed on one side of the inclined block 32. A filter component 34 is installed on the side of the magnetic block 33 away from the inclined block 32. A pipe interface 36 is installed on one side of the cleaning housing 31. A sealing ring 37 is fitted onto the outer surface of the pipe interface 36. A water outlet 35 is installed at the bottom of the pipe interface 36.

[0027] By adopting the above technical solution, when using the cleaning component 3, the metal shavings generated during processing will enter the cleaning housing 31 under the action of suction. Then, the shavings in the gas are filtered by the filter component 34. The filtered shavings will fall onto the surface of the magnetic block 33. Through the magnetic force of the magnetic block 33, the shavings can be further attracted and collected, preventing the shavings from moving continuously in the cleaning housing 31 under the action of airflow and causing damage to the filter component 34. Liquid generated during processing may also enter the cleaning housing 31. The liquid in the cleaning housing 31 can be discharged through the external pipe of the outlet 35, which improves the liquid drainage function of the suction cup and enhances its practicality.

[0028] Specifically, the filter assembly 34 includes a reinforcing frame 341, a filter screen 342, a sealing block 343, a support plate 344, and a handle 345. The reinforcing frame 341 is provided on one side of the magnetic block 33, and the support plate 344 is fixedly connected to one side of the reinforcing frame 341. A sealing block 343 is provided at the connection between the support plate 344 and the reinforcing frame 341. A handle 345 is fixedly connected to the surface of the support plate 344 away from the reinforcing frame 341. The filter screen 342 is provided inside the reinforcing frame 341.

[0029] By adopting the above technical solution, when using the filter assembly 34, the suction cup uses suction to pull debris into the cleaning housing 31. When the debris passes through the filter screen 342, it is filtered to one side of the filter screen 342. At the same time, when drainage is required, the filter screen 342 can filter the debris in the liquid to prevent debris from clogging the pipe. When the filter screen 342 needs to be replaced and cleaned, the reinforcing frame 341 can be moved by pulling the handle 345 to remove the assembly for replacement and cleaning of the filter screen 342. After completion, it can be reinstalled. The sealing block 343 can enhance the sealing of the cleaning housing 31, preventing it from affecting the normal use of the suction cup, improving the replacement function of the filter screen 342, and enhancing functionality.

[0030] Specifically, a cleaning port is provided on one side surface of the cleaning shell 31, and a baffle is provided inside the cleaning port. A sealing sleeve is fitted onto the surface of the baffle.

[0031] By adopting the above technical solution, the cleaning port facilitates the cleaning of debris by operators, and the cooperation between the baffle and the sealing strip improves the sealing performance of the cleaning shell 31, thus avoiding affecting the normal use of the suction cup.

[0032] In this embodiment, during use: When using the cleaning component 3, the metal shavings generated during processing enter the cleaning housing 31 under the suction force. The shavings are then filtered by the filter component 34, and the filtered shavings fall onto the surface of the magnetic block 33. The magnetic force of the magnetic block 33 further attracts and collects the shavings, preventing them from moving continuously within the cleaning housing 31 under the influence of airflow and damaging the filter component 34. Liquid generated during processing may also enter the cleaning housing 31. The liquid in the cleaning housing 31 can be discharged through the external pipe at the outlet 35, thus improving the suction cup's drainage function and enhancing its practicality. When using the filter component 34, the suction cup uses suction to pull the shavings into the cleaning housing. In the housing 31, debris is filtered to one side of the filter screen 342 when passing through it. Simultaneously, when drainage is required, the filter screen 342 can filter debris from the liquid, preventing blockage of the pipes. When the filter screen 342 needs to be replaced or cleaned, the reinforcing frame 341 can be moved by pulling the handle 345 to remove the component for replacement and cleaning. After completion, it can be reinstalled. The sealing block 343 enhances the sealing of the cleaning housing 31, preventing interference with the normal use of the suction cup. This improves the replacement function of the filter screen 342 and enhances its functionality. The cleaning port facilitates debris removal by operators. The cooperation of the baffle and sealing strip further improves the sealing of the cleaning housing 31, preventing interference with the normal use of the suction cup.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that, specifically, the positioning component 7 includes a motor 71, a bidirectional screw 72, a threaded block 73, a side plate 74, a stop plate 75, a stop rod 76, a connecting block 77, and a mounting block 78. A mounting block 78 is provided on one side of the suction cup base 2, a motor 71 is mounted on one side of the mounting block 78, a bidirectional screw 72 is mounted on the output end of the motor 71, a threaded block 73 is threadedly connected to the surface of the bidirectional screw 72, a connecting block 77 is fixedly connected to the top of the threaded block 73, a stop rod 76 is fixedly connected to one side of the connecting block 77, a side plate 74 is provided on the side of the stop rod 76 away from the connecting block 77, and a stop plate 75 is provided on the top of the side plate 74.

[0035] By adopting the above technical solution, when using the positioning component 7, if the suction cup needs to fix a small workpiece or fixture, the bottom of the workpiece has less contact with the suction hole 5, resulting in an unsatisfactory fixing effect. This may cause the workpiece to move left and right, affecting normal processing. The motor 71 is started, which drives the bidirectional screw 72 to rotate. The screw block 73 and the connecting block 77 further drive the abutment 76 to position the two sides of the workpiece, preventing the workpiece from moving left and right during processing. At the same time, when it is necessary to fix thinner materials, the height of the abutment plate 75 can be adjusted to position and limit the edges and corners of the material, preventing the edges and corners of thinner materials from lifting under the suction force of the suction cup. This improves the positioning function of the suction cup and enhances its practicality.

[0036] Specifically, a screw rod runs through the interior of the side plate 74, a knob is installed on the top of the screw rod, and a movable groove is opened at the bottom of the side plate 74.

[0037] By adopting the above technical solution, the operation of the knob and screw makes it easy for the operator to adjust the position of the side plate 74 in the movable slot, thus expanding the scope of application.

[0038] In this embodiment, when using the positioning component 7, if the suction cup needs to fix a small workpiece or fixture, the bottom of the workpiece has less contact with the suction hole 5, resulting in an unsatisfactory fixing effect. This may cause the workpiece to move left and right, affecting normal processing. Starting the motor 71 drives the bidirectional screw 72 to rotate, which in turn drives the abutment 76 via the threaded block 73 and connecting block 77 to position the workpiece on both sides, preventing left and right movement during processing. Simultaneously, when fixing thinner materials, the height of the abutment plate 75 can be adjusted to position and limit the edges and corners of the material, preventing the edges and corners from lifting under the suction force of the suction cup. This improves the positioning function of the suction cup and enhances its practicality. The combination of the knob and screw allows the operator to easily adjust the position of the side plate 74 in the movable slot, expanding its applicability.

[0039] The structure and operating principle of the CNC lathe body 1, suction cup base 2, suction cover 4, suction hole 5 and workpiece fixture 6 in this utility model have been disclosed in a vacuum suction cup for CNC lathes disclosed in Chinese patent application number 202321864290.5.

[0040] The working principle and usage of this utility model are as follows: This utility model is designed to adjust a vacuum chuck used in CNC lathes. When using the cleaning component 3, metal debris generated during machining enters the cleaning housing 31 under the suction of air. The debris is then filtered by the filter component 34, and the filtered debris falls onto the surface of the magnetic block 33. The magnetic force of the magnetic block 33 further attracts and collects the debris, preventing it from continuously moving within the cleaning housing 31 under the influence of airflow and damaging the filter component 34. Liquid generated during machining may also enter the cleaning housing 31. The external pipe connected to the outlet 35 allows liquid to be discharged from the cleaning housing 31, improving the suction cup's drainage function and enhancing its practicality. When using the filter assembly 34, the suction cup uses suction to draw debris into the cleaning housing 31. The debris is filtered to one side of the filter screen 342 as it passes through the filter screen. Simultaneously, when drainage is needed, the filter screen 342 filters out debris from the liquid, preventing blockage of the pipe. When the filter screen 342 needs replacement or cleaning, the handle 345 can be pulled to move the reinforcing frame 341, allowing the assembly to be removed for replacement and cleaning. After completion, it can be reinstalled. The sealing block 343 enhances the sealing performance of the cleaning housing 31, preventing it from affecting the normal use of the suction cup. It also improves the replaceability of the filter screen 342, enhancing its functionality. The cleaning port facilitates the removal of debris by operators. The cooperation between the baffle and the sealing strip further improves the sealing performance of the cleaning housing 31, preventing it from affecting the normal use of the suction cup. This utility model addresses the adjustment of a vacuum suction cup used on a CNC lathe. When using the positioning component 7, if the suction cup needs to fix a small workpiece or fixture, the bottom of the workpiece has less contact with the suction hole 5, resulting in an unsatisfactory fixing effect. This may cause the workpiece to move left and right, affecting normal processing. The motor 71 is started, which drives the bidirectional screw 72 to rotate. The screw block 73 and the connecting block 77 then drive the abutment 76 to position the workpiece on both sides, preventing the workpiece from moving left and right during processing. When it is necessary to fix thinner materials, the height of the abutment plate 75 can be adjusted to position and limit the edges and corners of the material, preventing the edges and corners of thinner materials from lifting under the suction force of the suction cup. This improves the positioning function of the suction cup and enhances its practicality. The operation of the knob and screw allows the operator to easily adjust the position of the side plate 74 in the movable slot, expanding its application range.
