[0002] In metal processing, wood processing, and composite material cutting, beveling machines are key pieces of equipment widely used for processes such as chamfering, milling, and grinding workpiece edges. Beveling machines typically require precise control of the workpiece's position and orientation along multiple axes (such as X, Y, and Z axes) to ensure processing accuracy and efficiency.

[0003] Existing beveling machine feeding mechanisms mostly use manual adjustment or simple mechanical clamping methods, which are inconvenient to adjust. When processing workpieces of different sizes or shapes, traditional mechanisms often require frequent manual adjustment of the clamping distance, which not only reduces production efficiency but also increases the labor intensity of operators.

[0014] Example 1 like Figures 1-5 As shown, a Y-axis feeding mechanism for a beveling machine is provided, including a first base 1, a feeding assembly 2, a first linear drive module 3, a mounting plate 6, and a flipping mechanism 5. The feeding assembly 2 is disposed on the first base 1 and includes the first linear drive module 3 and the mounting plate 6. The bottom of the first linear drive module 3 is fixed to the first base 1 and is used to drive the mounting plate 6 to move along the Y-axis direction. The mounting plate 6 has a clamping bottom plate and a clamping top plate on its side. The flipping mechanism 5 is mounted on the mounting plate 6 and is used to drive the clamping top plate to flip axially to adjust its distance from the clamping bottom plate. The first linear drive module 3 can drive the mounting plate 6 and the clamping base plate, clamping top plate and flipping mechanism 5 connected to the mounting plate 6 to move as a whole along the Y-axis direction. Before moving, the flipping mechanism 5 drives the clamping top plate to flip axially to reduce the gap between the clamping top plate and the clamping base plate, and clamps and fixes the workpiece placed in this gap. Subsequently, the first linear drive module 3 pushes the mounting plate 6 to move as a whole along the Y-axis direction with the first base 1 as support, so as to accurately feed the workpiece into or out of the cutting area along the Y-axis direction.

[0015] like Figure 2As shown, in order to better drive the overall back-and-forth movement of the mounting plate 6, a first linear drive module 3 was designed. This first linear drive module 3 includes a first support base 31, a first mounting bracket 32, a first lead screw 33, a first guide rail 34, a first motor 35, a first slider 36, a nut seat 37, and a slide table 38. The first support base 31 is fixed to the first base 1, the first mounting bracket 32 ​​is fixed to the first support base 31, and the two ends of the first lead screw 33 are connected to the first mounting bracket 32 ​​via bearings. The first motor 35 is used to drive the first lead screw 33 to rotate. The nut seat 37 is threaded with the first lead screw 33. The first guide rail 34 is fixed on the first mounting bracket 32, the first slider 36 is slidably connected to the first guide rail 34, the slide table 38 is fixedly connected to the nut seat 37 and the first slider 36, and the slide table 38 is fixedly connected to the side of the mounting plate 6. The first motor 35 drives the first lead screw 33 (high-precision ball screw) to rotate through the coupling. The nut seat 37 is threadedly engaged with the first lead screw 33 to convert the rotational motion into linear motion. The first guide rail 34 (high-rigidity roller / ball linear guide) is installed in parallel, and the first slider 36 slides on the guide rail to ensure the stability of the movement trajectory of the slide table 38 and prevent deviation or vibration.

[0016] like Figure 4As shown, the flipping mechanism 5 includes a second bearing seat 51, a first connecting shaft 52, a third motor 54, a first clamping top plate 53, and a second clamping top plate 55. The second bearing seat 51 is fixed to the side of the mounting plate 6. The two ends of the first connecting shaft 52 are rotatably connected through the second bearing seat 51. The third motor 54 is fixed to the mounting plate 6, and its output end is connected to the first connecting shaft 52. The first clamping top plate 53 and the second clamping top plate 55 are sleeved on the first connecting shaft 52 and flip synchronously with it. The third motor 54 (usually a servo motor or stepper motor) receives control signals and outputs precise rotational motion. The transmission method is that the third motor 54 is directly connected to the first connecting shaft 52 through a coupling to achieve high-response control. The third motor 54 has a built-in encoder to monitor the rotation angle in real time to ensure accurate flipping position. The first connecting shaft 52 (usually hardened steel or stainless steel) is connected to the second bearing seat 51. (Deep groove ball bearings or angular contact bearings) provide support to ensure low friction and high rigidity rotation. The bearings are preloaded to prevent axial / radial movement and improve motion stability. The first clamping top plate 53 and the second clamping top plate 55 are fixed to the first connecting shaft 52 and rotate synchronously with the shaft. Preferably, each clamping top plate 53 has a first through hole for the first connecting shaft 52 to pass through. The surface of the first connecting shaft 52 has an axial protrusion 521. The first clamping top plate 53 and the second clamping top plate 55 have limiting grooves 531 that mate with the protrusion 521. The open ends of the clamping top plates are locked with fasteners. The first clamping top plate 53 and the second clamping top plate 55 can move in a specific direction to adjust the distance between them, accommodating workpieces of different widths. They are also locked to the surface of the first connecting shaft 52 with fasteners. The mounting plate 6 has a guide groove 61 on its side. Figure 3 As shown, the first bracket 44 passes through the guide groove 61 and is connected to the first clamping base plate 47. The guide groove 61 restricts the range of motion of the first bracket 44.

[0017] like Figure 3As shown, the mounting plate 6 is provided with a limiting clamping mechanism 4, including: a first clamping base plate 47, a second clamping base plate 48, a second motor 41, a first bracket 44, a second lead screw 42, a first bearing seat 43, a second guide rail 46, and a second slider 45. The first clamping base plate 47 and the second clamping base plate 48 are arranged in parallel. The second motor 41 drives the second lead screw 42 to rotate. The two ends of the second lead screw 42 are connected to the side of the mounting plate 6 through the first bearing seat 43. The second motor 41 is fixed to the side of the mounting plate 6. The first bracket 44 is threaded to the second lead screw 42 and is fixedly connected to the first clamping base plate 47. The second guide rail 46 cooperates with the second slider 45 to limit the movement trajectory of the first clamping base plate 47. The second guide rail 46 is fixedly connected to the side of the mounting plate 6. The second slider 45 is fixedly connected to the first clamping base plate 47. The first clamping base plate 47 is fixedly connected to the mounting plate 6, thus limiting the movement of the first clamping base plate 47. The clamping mechanism 4 uses an adjustable double-clamping base plate structure to achieve precise positioning and clamping of the workpiece, suitable for processing workpieces of different sizes. A second motor 41 (usually a servo motor or stepper motor) receives control signals and outputs rotational motion. A second lead screw 42 (ball screw or trapezoidal lead screw) drives the rotation of the second lead screw 42 directly via a coupling. The first clamping base plate 47 is fixed to the side of the mounting plate 6 and remains stationary. The first clamping base plate 47 is connected to the second lead screw 42 via a first bracket 44 and moves with the lead screw, achieving precise adjustment of the distance between the two base plates. The second guide rail 46 cooperates with the second slider 45 to ensure that the first clamping base plate 47 moves in a straight line without offset or jamming. The limiting clamping mechanism 4 uses a servo motor to drive a precision lead screw, achieving adjustable spacing between the double clamping base plates and ensuring stable positioning of the workpiece during processing. Combined with guide rail guidance and closed-loop control, it can adapt to workpieces of different sizes and materials, improving the accuracy and automation level of bevel machining.

[0018] like Figure 5 As shown, a positioning pin 7 is installed on the first clamping base plate 47. The positioning pin 7 is used to engage with the positioning hole of the workpiece to constrain the circuit board to be accurately positioned and clamped, ensuring that the clamping position is placed in the predetermined area, so as to avoid accidental contact with non-clamping areas and damage to the workpiece.

[0019] Working principle: The workpiece (such as a circuit board) is placed between the first clamping base plate 47 and the second clamping base plate 48. A positioning pin 7 engages with the positioning hole on the workpiece to ensure accurate initial positioning in the X / Y plane. The rigid design of the positioning pin 7 prevents workpiece displacement, making it particularly suitable for repeated positioning during batch processing. The second motor 41 drives the second lead screw 42 to rotate, causing the first bracket 44 and the first clamping base plate 47 to move along the second guide rail 46, adjusting and fixing the distance between the second clamping base plate 48 to accommodate the workpiece width. The second guide rail 46, in conjunction with the second slider 45, guides and ensures smooth movement. The third motor 54 drives the first connecting shaft 52 to rotate, causing the first clamping top plate 53 and the second clamping top plate 55 to flip downwards, pressing the top of the workpiece. The servo motor's built-in encoder provides real-time angle feedback. Ensure uniform clamping force; the convex strip 521-limiting groove 531 structure prevents the top plate from slipping, and the clamping force can be controlled by the motor torque to avoid workpiece deformation. The first motor 35 starts and pushes the nut seat 37 and slide table 38 along the first guide rail 34 through the first lead screw 33, driving the mounting plate 6 and the overall clamping mechanism (including the workpiece) to move along the Y-axis. The high-precision ball screw + roller guide combination eliminates backlash and ensures that the feeding trajectory is without deviation. The workpiece is sent to the bevel tool holder processing area (such as below the milling cutter or laser head), and the edge cutting is completed by the external processing system. After processing, the first motor 35 reverses and drives the mounting plate 6 to return to the initial position along the Y-axis. The third motor 54 reverses and lifts the clamping top plate; the second motor 41 adjusts the clamping bottom plate spacing to facilitate the removal of the finished product and the placement of the new workpiece.
