Technical Field
[0001] This utility model relates to the field of CNC machining technology, specifically a CNC machining device suitable for clamping workpieces of various specifications. Background Technology
[0002] Currently, CNC machining is a commonly used machining method in mechanical processing, but drilling is still generally done manually, that is, the workpiece is fixed on a workbench and the height of the electric drill bit is manually controlled to complete the drilling.
[0003] Publication No. CN108213484B discloses a CNC machining device. By opening a solenoid valve, a bidirectional pump draws liquid from the lower end of a hydraulic plate and inputs the liquid into the hydraulic space at the upper end of the hydraulic plate, thereby controlling the downward movement of the drilling device. The sealing gasket on the outside of the hydraulic plate provides a sealing effect, allowing the hydraulic plate to move without rotating, thus reducing friction and wear. Furthermore, the guide block and guide rail cooperate to prevent free rotation of the hydraulic plate. Simultaneously, a high-speed motor drives the drill bit to rotate at high speed, with the transmission shaft providing support and driving the rotation, thereby completing the drilling work. The cooperation between the annular limiting plate and the fixed rotating plate provides auxiliary support, preventing excessive force from damaging the high-speed motor. However, this patent still has the following problems in actual use:

[0019] Compared with the prior art, the beneficial effects of this utility model are: This CNC machining device, suitable for clamping workpieces of various specifications, by setting up a clamping component, enables the clamping component to clamp workpieces of different sizes and shapes, thereby improving the clamping efficiency of the workpieces and preventing workpiece displacement during processing. It also reduces the increase in costs to a certain extent. The specific details are as follows:
[0020] 1. By setting up a clamping assembly, after the workpiece is placed on the placement table, rotating the worm gear drives the worm wheel to rotate. The rotation of the worm wheel drives the rotation of the double-ended lead screw. The rotation of the double-ended lead screw causes the threaded sleeve to move. Simultaneously, the threaded sleeve is fixedly connected to the clamping plate, which is through-connected to the placement table. The cooperation between the clamping plate and the placement table provides a limiting effect on the threaded sleeve, allowing it to move on the double-ended lead screw. The movement of the threaded sleeve causes the clamping plate to move, and the clamping plate simultaneously... The continuous movement of the threaded sleeve allows for the clamping of workpieces of different sizes. Simultaneously, the first, second, and third rotating plates are rotatable, enabling them to rotate accordingly based on the shape of the workpiece when clamping it. This allows for better clamping of workpieces of different shapes, improving clamping efficiency. Furthermore, the rubber blocks increase friction with the workpiece, preventing workpiece misalignment and further enhancing processing efficiency.
[0021] 2. By setting up a placement slot, an electric push rod, a workpiece, a linear guide rail, a sliding sleeve, a connecting rod, and a sliding rod, the electric push rod is activated via a control terminal. This allows the output end of the electric push rod to move the workpiece, enabling it to process one side of the workpiece. Simultaneously, the linear guide rail is activated via the control terminal, causing the sliding sleeve to move. The movement of the sliding sleeve, in turn, moves the connecting rod. This movement causes the sliding sleeve to slide on the sliding rod. Furthermore, the movement of the connecting rod also moves another workpiece, allowing it to process the top surface of the workpiece. This improves the efficiency of workpiece processing.

At the same time, it can also reduce the increase in cost to a certain extent. The linear guide 11 is model BGXH358E.
[0031] A first connecting groove 1704 is formed on one side surface of the clamping plate 1703. A first stabilizing block 1705 is fixedly connected to the center of the first connecting groove 1704. A first rotating shaft 1706 is rotatably connected to one side surface of the first stabilizing block 1705. A first rotating plate 1707 is rotatably connected to the side surface of the first rotating shaft 1706 away from the first stabilizing block 1705.

The worm 1718 is rotatably connected to the groove 16 and is also passed through the placement platform 7. Figure 3As shown, rotating the worm gear 1718 causes the worm wheel 1717 to rotate, which in turn drives the double-ended lead screw 1701 to rotate. The rotation of the double-ended lead screw 1701 then moves the threaded sleeve 1702. Simultaneously, the threaded sleeve 1702 is fixedly connected to the clamping plate 1703, which is also connected to the placement platform 7. The cooperation between the clamping plate 1703 and the placement platform 7 limits the movement of the threaded sleeve 1702, allowing it to move on the double-ended lead screw 1701. This movement of the threaded sleeve 1702, in turn, drives the clamping plate 1703 to move. Simultaneously, the clamping plate 1703, under the continuous movement of the threaded sleeve 1702, can clamp workpieces of different sizes. The first rotating plate 1707, the second rotating plate 1711, and the third rotating plate 1715 are rotatable, allowing them to rotate accordingly based on the shape of the workpiece when clamping workpieces of different shapes. This improves the clamping efficiency by better clamping different shaped workpieces. Furthermore, the rubber block 1716 increases the friction between the workpiece and the rubber block, preventing workpiece displacement and further improving processing efficiency.
[0032] A placement groove 8 is provided on one side surface of the housing 2. An electric push rod 9 is fixedly installed inside the placement groove 8. A machined part 10 is fixedly connected to the side surface of the electric push rod 9 away from the placement groove 8. A sliding sleeve 14 is fixedly connected to the side surface of the connecting rod 13 away from the sliding sleeve 12. A sliding rod 15 is slidably connected inside the sliding sleeve 14. The top surface of the sliding rod 15 is fixedly connected to the housing 2, and the bottom surface of the connecting rod 13 is fixedly connected to the machined part 10. Sliding blocks 18 are symmetrically installed on both sides of the surface of the sliding door 4. The sliding blocks 18 are slidably connected to the sliding groove 3. Figure 1 , 2As shown in Figure 6, the electric push rod 9 is activated by the control terminal, which enables the output end of the electric push rod 9 to drive the movement of the workpiece 10, allowing the workpiece 10 to process one side of the workpiece. At the same time, the linear guide rail 11 is activated by the control terminal, which drives the movement of the sliding sleeve 12. The movement of the sliding sleeve 12 drives the movement of the connecting rod 13, which in turn drives the sliding sleeve 14 to slide on the sliding rod 15. The movement of the connecting rod 13 also drives the movement of another workpiece 10, allowing the other workpiece 10 to process the top surface of the workpiece, thereby improving the processing efficiency of the workpiece. The electric push rod 9 is model LAM33-A. The sliding of the slider 18 and the slide groove 3 drives the sliding of the sliding door 4. The slider 18 is a T-block, and the slide groove 3 is a T-slot.
[0033] Working principle: Before using this CNC machining device suitable for clamping workpieces of various specifications, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6 As shown, after the workpiece is placed on the placement table 7, the worm gear 1718 is rotated, causing the worm wheel 1717 to rotate. The rotation of the worm wheel 1717, in turn, causes the double-ended lead screw 1701 to rotate. This rotation of the double-ended lead screw 1701 then moves the threaded sleeve 1702. Simultaneously, the threaded sleeve 1702 is fixedly connected to the clamping plate 1703, which is connected through the placement table 7. The cooperation between the clamping plate 1703 and the placement table 7 limits the movement of the threaded sleeve 1702, allowing it to move on the double-ended lead screw 1701. This movement of the threaded sleeve 1702 then moves the clamping plate 1702. The movement of the holding plate 1703, coupled with the continuous movement of the threaded sleeve 1702, allows for the clamping of workpieces of different sizes. Simultaneously, the first rotating plate 1707, the second rotating plate 1711, and the third rotating plate 1715 are rotatable, allowing them to rotate according to the shape of the workpiece when clamping workpieces of different shapes. This improves the clamping efficiency by better clamping different shaped workpieces. Furthermore, the rubber block 1716 increases the friction between the workpiece and the rubber block, preventing workpiece displacement and further enhancing processing efficiency.
[0034] Secondly, the electric push rod 9 is activated by the control terminal, so that the output end of the electric push rod 9 can drive the movement of the workpiece 10, thereby enabling the workpiece 10 to process one side of the workpiece. At the same time, the linear guide rail 11 is activated by the control terminal, so that the linear guide rail 11 drives the movement of the sliding sleeve 12. The movement of the sliding sleeve 12 drives the movement of the connecting rod 13. The movement of the connecting rod 13 drives the sliding sleeve 14 to slide on the sliding rod 15. At the same time, the movement of the connecting rod 13 can also drive the movement of another workpiece 10, thereby enabling the other workpiece 10 to process the top surface of the workpiece, thus improving the processing efficiency of the workpiece.
