Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, specifically a mobile CNC drilling machine. Background Technology

[0002] A CNC drilling machine is a machine tool used for drilling workpieces. Its movement and machining process are controlled by a computer numerical control (CNC) system. CNC drilling machines are characterized by high precision, high efficiency, and a high degree of automation, and are widely used in the metal processing industry. The working principle of a CNC drilling machine is to place the drill bit on the spindle, and drive the spindle to rotate via a motor. The CNC system controls the spindle speed, feed rate, and machining path according to pre-programmed instructions to perform the drilling operation on the workpiece.

[0003] A mobile CNC drilling machine is a type of CNC drilling machine with mobility. It typically shares similar working principles and characteristics with traditional CNC drilling machines, but offers greater flexibility and mobility. Mobile CNC drilling machines can be moved between different work areas, making them suitable for situations requiring frequent changes in work position or drilling operations in different locations. They are usually equipped with wheels for both movement and anchoring between work areas.

[0004] Currently, existing mobile CNC drilling machines have poor overall integrity of material clamping and positioning devices, unreliable clamping and positioning effects, and during processing, the material is prone to deviation due to the action of the cutting tool, affecting processing accuracy. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing mobile CNC drilling machines do not provide reliable material clamping and positioning, causing materials to easily deviate and affecting processing accuracy.

[0006] To solve the above problems, the technical solution of this utility model is as follows: a mobile CNC drilling machine, including a base, a frame above the base, a gantry fixed to the top of the frame, a CNC drilling machine mounted on the gantry, the frame having a hollow interior, and a fixing groove formed on its top surface below the CNC drilling machine, with mounting grooves symmetrically arranged on both sides of the fixing groove, multiple rollers installed inside the mounting groove, and limiting components on both sides of the rollers inside the mounting groove, a fixing frame fixed to one side of the fixing groove on the top surface of the frame, a telescopic rod installed through the fixing frame, and a pressure plate installed at the movable end of the telescopic rod;

[0007] The limiting component includes a bidirectional lead screw rotatably mounted inside the frame, with movable blocks symmetrically threaded on both sides of the bidirectional lead screw, and a mounting frame fixed to the top of the movable blocks, with rollers installed inside the mounting frame.

[0008] Furthermore, casters are installed at all four corners of the base.

[0009] Furthermore, the gantry is provided with a Y-axis moving component, and a Z-axis moving component is installed on the Y-axis moving component, and the CNC drilling machine is installed on the Z-axis moving component.

[0010] Furthermore, a limiting rod is fixedly connected inside the frame, penetrating the movable block, and the limiting rod is located directly above the bidirectional lead screw.

[0011] Furthermore, one end of the bidirectional lead screw passes through the side wall of the frame and is fitted with a pulley. The pulley has at least two belt grooves, and every two adjacent pulleys are connected by belt drive.

[0012] Furthermore, a motor is connected to the end of the bidirectional lead screw of one of the limiting components, and the motor is mounted on the frame via a positioning bracket.

[0013] The advantages of this utility model compared with the existing technology are as follows: This utility model uses a motor to drive multiple bidirectional lead screws to rotate, causing the mounting frame and rollers to move. The rollers achieve clamping and limiting of the material, and the extension of the telescopic rod causes the pressure plate to move downward, pressing and fixing the material. The pressing of the pressure plate combined with the clamping and limiting of the rollers effectively prevents the material from deviating during drilling, thus improving the processing accuracy.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3 As shown, a mobile CNC drilling machine includes a base 1, a frame 2 on top of the base 1, casters 10 at the four corners of the bottom, a gantry frame 3 fixedly connected to the top of the frame 2, a CNC drilling machine 4 mounted on the gantry frame 3, a Y-axis moving assembly 11 on the gantry frame 3, a Z-axis moving assembly 12 mounted on the Y-axis moving assembly 11, and the CNC drilling machine 4 mounted on the Z-axis moving assembly 12. The frame 2 has a hollow interior, and a fixing groove is formed on its top surface below the CNC drilling machine 4. Installation grooves are symmetrically arranged on both sides of the fixing groove. Multiple rollers 5 are installed inside the installation grooves, and limiting components 6 are provided on both sides of the rollers 5 inside the installation grooves. A fixing frame 7 is fixedly connected to one side of the fixing groove on the top surface of the frame 2. A telescopic rod 8 is installed through the fixing frame 7, and a pressure plate 9 is installed at the movable end of the telescopic rod 8.

[0021] The design of the roller 5 reduces the resistance and friction when the material moves on the frame 2. The extension and retraction of the telescopic rod 8 allows the pressure plate 9 to move up and down, thereby achieving the pressing and fixing of the material.

[0022] like Figure 1 and Figure 4 As shown, the limiting component 6 includes a bidirectional lead screw 6.1 rotatably mounted inside the frame 2. Two movable blocks 6.2 are symmetrically threaded onto both sides of the bidirectional lead screw 6.1. A limiting rod 6.5, passing through the movable block 6.2, is fixed inside the frame 2 and is located directly above the bidirectional lead screw 6.1. A mounting frame 6.3 is fixed to the top of the movable block 6.2, and a roller 6.4 is installed inside the mounting frame 6.3. One end of the bidirectional lead screw 6.1 passes through the side wall of the frame 2 and is fitted with a pulley 6.6. The pulley 6.6 has at least two belt grooves, and every two adjacent pulleys 6.6 are connected by a belt 6.7. A motor 6.8 is connected to the end of the bidirectional lead screw 6.1 of one limiting component 6, and the motor 6.8 is mounted on the frame 2 via a positioning frame 6.9.

[0023] Motor 6.8 drives a bidirectional lead screw 6.1 to rotate. Under the action of pulley 6.6 and belt 6.7, the other bidirectional lead screws 6.1 rotate synchronously. The rotation of the bidirectional lead screws 6.1 causes the movable block 6.2 to drive the mounting frame 6.3 and rollers 6.4 to move. The distance between the two rollers 6.4 can be adjusted, and the two rollers 6.4 can clamp the material, effectively reducing the occurrence of material deviation.

[0024] In practical use, the material is placed on the frame 2, and the motor 6.8 drives multiple bidirectional lead screws 6.1 to rotate, causing the mounting frame 6.3 and rollers 6.4 to move. The rollers 6.4 clamp and limit the material, preventing it from deviating during movement. When the drilling position moves to below the CNC drilling machine 4, the telescopic rod 8 extends, causing the pressure plate 9 to move downwards, pressing and fixing the material to ensure stability during drilling. At the same time, the pressing of the pressure plate 9, combined with the clamping and limiting of the rollers 6.4, further prevents the material from deviating during drilling, improving processing accuracy.

[0025] The parts not disclosed in this utility model are all existing technologies, such as the Y-axis moving component 11, the Z-axis moving component 12, and the CNC drilling machine 4, etc. Their specific structures and working principles will not be described in detail.
