Description

Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms, in particular to a feeding mechanism for a workbench of a numerically controlled engraving and milling machine that is convenient for feeding materials. Background Art

[0002] CNC engraving and milling machine is a mechanical equipment that controls the movement of tools through computer programs for engraving and milling. It combines computer technology and traditional milling machine technology to provide a more efficient and precise processing solution for the manufacturing industry. In the process of CNC engraving and milling machine processing workpieces, feeding the workpiece is a key step.

[0003] Most CNC engraving and milling machines use manual feeding methods, which is relatively backward and inefficient in practical applications. Manual feeding not only increases the labor intensity of operators, but is also easily affected by human factors, making it difficult to ensure the accuracy and stability of feeding. Due to errors and uncertainties in human operation, workpieces may deviate or be damaged during the feeding process, thus affecting the subsequent processing quality and efficiency. Therefore, we propose a workbench feeding mechanism for CNC engraving and milling machines that is easy to feed. Utility Model Content

Manual feeding not only increases the labor intensity of operators, but is also easily affected by human factors, resulting in difficulty in ensuring the accuracy and stability of feeding. Due to errors and uncertainties in human operation, the workpiece may deviate or be damaged during the feeding process, thereby affecting the subsequent processing quality and efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a workbench feeding mechanism of a CNC engraving and milling machine that is convenient for feeding, comprising a base, a gantry is fixedly installed on the top of the base, a conveyor belt is arranged at the center of the upper end of the base, fixed plates are fixedly connected to the bottom positions on both sides of the inner wall of the gantry, processing tables are arranged on the upper ends of the two fixed plates, a first cylinder is fixedly installed on the opposite side of the bottom of the two fixed plates, a turning seat is arranged between the two processing tables, a motor is fixedly installed on the opposite side of the two processing tables, two clamps are arranged at the lower end of the turning seat, second cylinders are fixedly installed on the bottom of both sides of the turning seat, and the engraving and milling mechanism body is fixedly installed at the center of the top inside the gantry.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The CNC engraving and milling machine has a workbench feeding mechanism that is convenient for feeding. Through the design of the processing table, the fixed plate, the first cylinder, the turning seat, the motor, the second cylinder and the clamping plate, when the workpiece is transmitted to the bottom of the clamping mechanism through the conveyor belt, the two first cylinders can work synchronously to pull the two processing tables and the turning seat downward. In this process, immediately afterwards, through the drive of the two second cylinders, the two clamping plates can quickly clamp and fix the workpiece at the lower end. Subsequently, the first cylinder works again to drive the processing table to move upward and lift the workpiece to an appropriate height. By controlling the operation of the motor, the turning seat can be smoothly turned over and the clamped workpiece is accurately placed under the main body of the engraving and milling mechanism. This process not only ensures the stability of the workpiece during the engraving and milling process, but also realizes the rapid and accurate feeding of the workpiece. On the basis of the conveyor belt transmitting the workpiece, combined with the coordinated work of the cylinder and the motor, the stability and accuracy of the workpiece during the clamping, lifting and turning process are ensured. This feeding method is not only convenient and fast, but also greatly improves the processing efficiency and quality of the CNC engraving and milling machine, providing strong technical support for modern industrial production.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-4The utility model provides a technical solution: a workbench feeding mechanism of a CNC engraving and milling machine that is convenient for feeding, comprising a base 1, a gantry 2 is fixedly installed on the top of the base 1, a conveyor belt 3 is arranged at the center of the upper end of the base 1, fixed plates 5 are fixedly connected to the bottom positions of both sides of the inner wall of the gantry 2, a processing table 4 is arranged on the upper ends of the two fixed plates 5, a first cylinder 6 is fixedly installed on the opposite side of the bottom of the two fixed plates 5, a turning seat 7 is arranged between the two processing tables 4, a motor 8 is fixedly installed on the opposite side of the two processing tables 4, two clamping plates 10 are arranged at the lower end of the turning seat 7, second cylinders 9 are fixedly installed on the bottom of both sides of the turning seat 7, and an engraving and milling mechanism body 13 is fixedly installed at the center of the top of the gantry 2.

[0015] The front end and the rear end of the conveyor belt 3 extend to the outside of the gantry 2 respectively.

[0016] The first cylinder 6 is fixedly connected to the first piston rod through the output end at the top thereof. The top of the first piston rod passes through the outside of the fixed plate 5 and is fixedly connected to the bottom of the processing table 4. The first cylinder 6 can drive the lifting movement of the processing table 4 by controlling the extension and retraction of the first piston rod.

[0017] The motor 8 is fixedly connected to the main shaft through the output end on one side thereof. The opposite ends of the two main shafts respectively penetrate the outside of the two processing tables 4 and are respectively fixedly connected to the two sides of the flip seat 7. The motor 8 can drive the main shaft to rotate, and then drive the flip seat 7 to perform a flipping movement, thereby realizing the flipping of the workpiece.

[0018] The second cylinder 9 is fixedly connected to a second piston rod through an output end on one side thereof, and the opposite ends of the two second piston rods pass through the outside of the flip seat 7 and are fixedly connected to the opposite sides of the two clamps 10 respectively. This design enables the second cylinder 9 to drive the opening and closing movement of the clamps 10 by controlling the extension and retraction of the second piston rod, thereby achieving clamping and releasing of the workpiece and improving the stability and accuracy of feeding.

[0019] The inner wall of the gantry 2 is provided with slide grooves 11 corresponding to the upper ends of the two fixed plates 5, and the tops of the two processing tables 4 on the opposite sides are fixedly connected with sliders 12. The opposite sides of the two sliders 12 extend to the inside of the two slide grooves 11 and are slidably connected to the inner walls of the slide grooves 11, so that the processing table 4 can move smoothly along the slide grooves 11 during the lifting process, thereby improving the stability and accuracy of feeding.

[0020] Support legs are fixedly installed at the four corners of the base 1 and the bottom of the conveyor belt 3. These support legs not only provide stable support for the entire feeding mechanism, but also ensure the stability and reliability of the conveyor belt 3 during operation, thereby ensuring the smooth progress of the feeding process.

[0021] Working principle: First, the workpiece is transported to the inside of the gantry 2 through the conveyor belt 3. When the workpiece reaches the bottom of the clamping mechanism, the two first cylinders 6 start working. When the first cylinder 6 drives the first piston rod to descend, the processing table 4 will also descend accordingly, so that the flip seat 7 and the clamp 10 are close to the workpiece on the conveyor belt 3. Next, the second cylinder 9 starts working to drive the extension and retraction of the second piston rod. The opposite ends of the two second piston rods are fixedly connected to the opposite side of the clamp 10, so that the second cylinder 9 can control the opening and closing movement of the clamp 10. When the second cylinder 9 drives the second piston rod to retract, the clamp 10 will clamp the workpiece. After clamping is completed, the first cylinder 6 works again to drive the first piston rod to rise, so that the processing table 4 and the flip seat 7 rise with the workpiece. During the rising process, the slider 12 on the processing table 4 moves smoothly along the slide groove 11 to ensure the stability and accuracy of feeding. When the workpiece rises to a certain position, the motor 8 starts working. The motor 8 is connected to the main shaft through the output end, and the main shaft is fixedly connected to the two sides of the flip seat 7. The motor 8 drives the main shaft to rotate, thereby driving the flip seat 7 to flip. The flipping of the flip seat 7 enables the clamped workpiece to be accurately positioned below the engraving and milling mechanism body 13. Finally, the engraving and milling mechanism body 13 performs engraving and milling processing on the workpiece. After the processing is completed, the first cylinder 6 drives the processing table 4 to descend again, and the second cylinder 9 drives the clamping plate 10 to release the workpiece. The workpiece is sent out of the feeding mechanism through the conveyor belt 3, completing the entire feeding and processing process.

[0022] In summary: the CNC engraving and milling machine has a workbench feeding mechanism that is convenient for feeding. Through the design of the processing table 4, the fixed plate 5, the first cylinder 6, the turning seat 7, the motor 8, the second cylinder 9 and the clamping plate 10, when the workpiece is transmitted to the bottom of the clamping mechanism through the conveyor belt 3, the two first cylinders 6 can work synchronously to pull the two processing tables 4 and the turning seat 7 to move downward. In this process, then, through the drive of the two second cylinders 9, the two clamping plates 10 can quickly clamp and fix the workpiece at the lower end. Subsequently, the first cylinder 6 works again to drive the processing table 4 to move upward and lift the workpiece to With an appropriate height, by controlling the operation of the motor 8, the flip seat 7 can be flipped smoothly, and the clamped workpiece can be accurately placed under the engraving and milling mechanism body 13. This process not only ensures the stability of the workpiece during the engraving and milling process, but also realizes the rapid and accurate feeding of the workpiece. On the basis of the workpiece being transmitted by the conveyor belt 3, combined with the coordinated work of the cylinder and the motor 8, the stability and accuracy of the workpiece during the clamping, lifting and flipping processes are ensured. This feeding method is not only convenient and fast, but also greatly improves the processing efficiency and quality of the CNC engraving and milling machine, providing strong technical support for modern industrial production.
