Technical Field
[0001] This utility model relates to the field of pneumatic punching technology, specifically a pneumatic punching precision machining device. Background Technology
[0002] Pneumatic punch presses are precision machining devices that use compressed air to drive cylinders and achieve high-speed punching. They employ photoelectric protection technology and a micron-level stroke adjustment system to ensure machining accuracy. These devices are used for precision punching processes such as punching, shearing, and forming of metal and non-metal sheets and tubes, and are particularly suitable for the production of thin-film products in industries with strict requirements for precision and cleanliness, such as electronic components, automotive parts, and medical devices. However, current pneumatic punch presses still have the following shortcomings:
[0003] For example, patent document CN220497399U discloses a pneumatic punching device for sheet metal processing. This pneumatic punching device for sheet metal processing facilitates automated feeding when stamping and bending sheet metal parts, and can hold and limit the sheet metal parts during stamping and bending to prevent deviation during processing. However, it does not have a complete limiting and buffering mechanism in place during the stamping process, which can easily lead to deviations during stamping, thereby affecting the overall processing accuracy. Utility Model Content
[0004] The purpose of this invention is to provide a pneumatic punching machine precision machining device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic punch press precision machining device, comprising a punch press base and a limiting component. The punch press base is an integrated structure, and a support seat is provided at the rear end of the upper surface of the punch press base. A stamping fixing seat is provided at the front end of the upper surface of the punch press base. The limiting component is disposed inside the punch press base and includes a hexagonal slide groove, a hexagonal column, a limiting slide groove, a buffer spring, a limiting piston, and a support rod. The hexagonal slide groove is opened at both ends inside the punch press base, and a hexagonal column is slidably connected inside the hexagonal slide groove. Limiting slide grooves are opened at both the front and rear sides of the hexagonal slide groove, and a buffer spring is provided on the lower surface inside the limiting slide groove. A limiting piston is slidably connected inside the limiting slide groove.
[0006] Furthermore, a support rod is installed on the upper surface of the limiting piston, and the lower surface of the limiting piston is connected to the top of the buffer spring.
[0007] Furthermore, a pneumatic stamping rod is provided on the front side of the upper end of the support base, and a stamping movable seat is installed at the bottom of the pneumatic stamping rod.
[0008] Furthermore, both the upper surfaces of the stamping movable seat and the stamping fixed seat are provided with mounting grooves, and the two ends of the lower surface of the stamping movable seat are connected to the top of the hexagonal column and the top of the support rod.
[0009] Furthermore, the surface of the support base is provided with a cleaning component for cleaning up waste debris, and the cleaning component includes a servo motor, a threaded fixing rod, an internally threaded movable cylinder, and a support bar.
[0010] Furthermore, the servo motor is located at the lower end of the rear surface of the support base, and the output end of the servo motor is connected to a threaded fixing rod via a coupling.
[0011] Furthermore, the outer surface of the threaded fixing rod is threadedly connected to an internally threaded movable cylinder, and a support bar is provided on the front side of the internally threaded movable cylinder.
[0012] Furthermore, the cleaning assembly also includes a T-shaped cleaning cotton and a limiting movable rod, and the upper surface of the support bar is provided with a T-shaped cleaning cotton, and the two ends of the rear surface of the support bar are installed with limiting movable rods.
[0013] This utility model provides a pneumatic punching precision machining device, which has the following beneficial effects:
[0014] 1. This utility model incorporates a limiting component, which includes a hexagonal slide groove, a hexagonal column, a limiting slide groove, a buffer spring, a limiting piston, and a supporting rod. During use, the pressing movable seat moves downwards, causing the hexagonal column to slide downwards along the inner side of the hexagonal slide groove. The sliding connection between the hexagonal column and the inner side of the hexagonal slide groove provides initial positioning for the movement of the pressing movable seat. Simultaneously, the supporting rod drives the limiting piston to move downwards along the inner side of the limiting slide groove. The sliding connection between the limiting piston and the inner side of the limiting slide groove further limits the movement of the pressing movable seat. This causes the limiting piston to compress the buffer spring, which in turn buffers the movement of the limiting piston, preventing machine vibration from affecting the limiting piston's position. Therefore, this device can stably limit the pressing movable seat during the stamping process, thereby improving the overall stamping accuracy.
[0015] 2. This utility model incorporates a cleaning assembly, which includes a servo motor, a threaded fixing rod, an internally threaded movable cylinder, and a support bar. The assembly also includes a T-shaped cleaning cotton and a limiting movable rod. In use, the servo motor is activated, causing the threaded fixing rod to rotate. This rotation, in turn, causes the internally threaded movable cylinder to move forward along the lower end of the support base. The movable cylinder then moves the support bar forward, which in turn moves the T-shaped cleaning cotton along the inner side of the mounting groove. The T-shaped cleaning cotton cleans the inner side of the mounting groove. The limiting movable rod, through its sliding connection with the lower end of the support base, limits the movement of the support bar. This allows the device to clean the inner side of the mounting groove, preventing the accumulation of waste materials that could affect normal processing. Attached Figure Description

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0021] like Figures 1 to 3 As shown, a pneumatic punch press precision machining device includes a punch press base 1 and a limiting component 4. The punch press base 1 is an integral structure, with a support seat 2 provided at the rear end of the upper surface of the punch press base 1 and a stamping fixing seat 3 provided at the front end of the upper surface of the punch press base 1. The limiting component 4 is disposed inside the punch press base 1 and includes a hexagonal slide 401, a hexagonal column 402, a limiting slide 403, a buffer spring 404, a limiting piston 405, and a support rod 406. The hexagonal slide groove 401 is opened at both ends inside the punch press base 1, and a hexagonal column 402 is slidably connected inside the hexagonal slide groove 401. Limiting slide grooves 403 are opened at both the front and rear sides of the hexagonal slide groove 401, and a buffer spring 404 is provided on the lower surface inside the limiting slide groove 403. A limiting piston 405 is slidably connected inside the limiting slide groove 403. A support rod 406 is installed on the upper surface of the limiting piston 405, and the lower surface of the limiting piston 405 is connected to the top of the buffer spring 404.
[0022] The specific operation is as follows: During use, the stamping movable seat 6 moves downward, causing the hexagonal column 402 to slide downward along the inner side of the hexagonal slide groove 401. Through the sliding connection between the hexagonal column 402 and the inner side of the hexagonal slide groove 401, the movement of the stamping movable seat 6 is initially positioned. At the same time, the support rod 406 drives the limiting piston 405 to move downward along the inner side of the limiting slide groove 403. Through the sliding connection between the limiting piston 405 and the inner side of the limiting slide groove 403, the movement of the stamping movable seat 6 is further limited, so that the limiting piston 405 compresses the buffer spring 404, so that the buffer spring 404 plays a buffering role on the movement of the limiting piston 405, which can prevent the machine vibration from affecting the limiting of the limiting piston 405.
[0023] Please refer to Figures 1 to 3 A pneumatic stamping rod 5 is provided on the front side of the upper end of the support base 2, and a stamping movable seat 6 is installed at the bottom of the pneumatic stamping rod 5. Both the upper surfaces of the stamping movable seat 6 and the stamping fixed seat 3 are provided with mounting grooves 7, and the two ends of the lower surface of the stamping movable seat 6 are connected to the top of the hexagonal column 402 and the top of the support column 406. A cleaning assembly 8 for cleaning waste is provided on the surface of the support base 2, and the cleaning assembly 8 includes a servo motor 801, a threaded fixed rod 802, an internally threaded movable cylinder 803, and a support bar 804. The servo motor 801 is located at the lower end of the rear surface of the support base 2, and the output end of the servo motor 801 is connected to a threaded fixing rod 802 via a coupling. The outer surface of the threaded fixing rod 802 is threadedly connected to an internally threaded movable cylinder 803, and a support bar 804 is provided on the front side of the internally threaded movable cylinder 803. The cleaning component 8 also includes a T-shaped cleaning cotton 805 and a limiting movable rod 806. The upper surface of the support bar 804 is provided with a T-shaped cleaning cotton 805, and the two ends of the rear surface of the support bar 804 are equipped with limiting movable rods 806.
[0024] The specific operation is as follows: During use, the pneumatic stamping rod 5 is started to drive the stamping movable seat 6 to move downward. Different stamping seats or stamping heads can be installed on the stamping movable seat 6 and the stamping fixed seat 3 through the mounting groove 7. After the stamping process is completed, the servo motor 801 is started, which drives the threaded fixed rod 802 to rotate. The threaded fixed rod 802 drives the internal threaded movable cylinder 803 to move forward along the lower end of the support seat 2. The internal threaded movable cylinder 803 drives the support bar 804 to move forward. Then, the support bar 804 drives the T-shaped cleaning cotton 805 to move along the inner side of the mounting groove 7. The T-shaped cleaning cotton 805 cleans the inner side of the mounting groove 7. The movement of the support bar 804 is limited by the sliding connection between the limiting movable rod 806 and the lower end of the support seat 2.
[0025] In summary, as Figures 1 to 3As shown, in use, this pneumatic punching precision machining device first allows different punching seats or punching heads to be installed on the punching movable seat 6 and the punching fixed seat 3 via the mounting slot 7. The pneumatic punching rod 5 is then activated, causing the punching movable seat 6 to move downwards. This downward movement of the punching movable seat 6 causes the hexagonal column 402 to slide downwards along the inner side of the hexagonal slide groove 401. The sliding connection between the hexagonal column 402 and the inner side of the hexagonal slide groove 401 provides initial positioning for the movement of the punching movable seat 6. Simultaneously, the supporting rod 406 causes the limiting piston 405 to move downwards along the inner side of the limiting slide groove 403. The sliding connection between the limiting piston 405 and the inner side of the limiting slide groove 403 further limits the movement of the punching movable seat 6, causing the limiting piston 405 to engage with the buffer spring 4. 04. Compression is applied so that the buffer spring 404 can buffer the movement of the limit piston 405, preventing the machine vibration from affecting the limit piston 405. After the stamping process is completed, the servo motor 801 is started, which drives the threaded fixing rod 802 to rotate. The threaded fixing rod 802 drives the internal threaded movable cylinder 803 to move forward along the lower end of the support base 2. The internal threaded movable cylinder 803 drives the support bar 804 to move forward. Then, the support bar 804 drives the T-shaped cleaning cotton 805 to move along the inner side of the mounting groove 7. The T-shaped cleaning cotton 805 cleans the inner side of the mounting groove 7. The movement of the support bar 804 is limited by the sliding connection between the limit movable rod 806 and the lower end of the support base 2.
