[0015] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.
[0016] like Figure 1 As shown, this application proposes a double-head sawing and milling machine, mainly comprising a loading mechanism 1, a sawing mechanism 2, and a milling mechanism 3. The loading mechanism 1 is used to clamp and position the product to be processed and can rotate around the X-axis to achieve switching between different processing steps; the sawing mechanism 2 is located on one side of the Y-axis of the loading mechanism 1 and is used for sawing the product; the milling mechanism 3 is located on the other side of the Y-axis of the loading mechanism 1 and is used for milling the product. The three mechanisms work together to simultaneously machine both ends of two sets of products, effectively improving processing efficiency and accuracy.
[0017] like Figure 1-2As shown, the loading mechanism 1 includes a reference frame 11 and a rotary drive 12 (such as a servo motor or a geared motor) that drives the reference frame 11 to rotate. Clamping components are provided on both opposite end faces of the reference frame 11, enabling simultaneous clamping of two sets of products for machining, effectively improving processing efficiency. The rotary drive 12 drives the reference frame 11 to rotate around the X-axis, adjusting the clamped products to different angles to meet processing requirements at different positions, eliminating the need for repeated clamping. During product loading, the rotary drive 12 rotates the clamping end faces of the reference frame 11 upwards for easier operator access.
[0018] like Figure 1-3 As shown, the clamping assembly includes a basic positioning part disposed on the end face of the reference frame 11. The basic positioning part is configured as a plurality of raised support blocks 111, which are discretely distributed on the end face of the reference frame 11, and their distribution range is set to conform to the shape of the product. When the product is loaded, it is placed directly on the raised support blocks 111, which can initially define the placement position of the product and prevent incorrect product placement. By dispersing the raised support blocks 111, large-area contact between the raised support blocks 111 and the product is avoided, reducing the risk of scratches on the product surface. At the same time, by adjusting the layout position of the raised support blocks 111, products of different shapes can be applied, thereby improving the clamping versatility.
[0019] like Figure 1-3 As shown, the clamping assembly also includes a straightening unit, which comprises an X-axis straightening and centering structure and a Y-axis straightening and centering structure disposed on the side of the end face of the reference frame 11. The X-axis straightening and centering structure consists of an X-axis reference block 112 and an X-axis push cylinder 113 arranged opposite each other along the X-axis, and the Y-axis straightening and centering structure consists of a Y-axis reference block 114 and a Y-axis push cylinder 115 arranged opposite each other along the Y-axis. The X-axis push cylinder 113 and the Y-axis push cylinder 115 simultaneously extend their push rods to clamp the product from two directions, so that the product is automatically straightened and centered in the reference position, ensuring the product's accurate position before processing, eliminating manual placement errors, and effectively improving the accuracy of subsequent sawing and milling processes.
[0020] like Figure 1-3 As shown, the clamping assembly also includes a Z-axis clamping part, which includes a rotary pressing cylinder 116 disposed on both sides of the Y-axis of the end face of the reference frame 11. When the product is placed in place and the position is corrected by the above-mentioned correction part, the rotary pressing cylinder 116 rotates to the top of the product and presses on the end face of the product to provide clamping force in the Z direction, which can prevent the product from shaking or displacing during the processing or rotation and repositioning process, and effectively ensure processing stability.
[0021] like Figure 1-3As shown, furthermore, flip-clamping components are provided on both sides of the X-axis of the end face of the reference frame 11 to clamp the two ends of the product to be processed along the X-axis. The flip-clamping components include two sets of reference brackets 117 and a flip-down clamping frame 118 rotatably connected to them. The two sets of reference brackets 117 are fixed on both sides of the Y-axis of the end face of the reference frame 11. The flip-down clamping frame 118 can be rotated to be parallel to the end face of the reference frame 11 and covers the product. Several telescopic cylinders 119 are provided on the flip-down clamping frame 118. When the flip-down clamping frame 118 is rotated to the correct position (parallel to the end face of the reference frame 11), the push rod ends of the telescopic cylinders 119 extend and clamp the product from above. When picking up or placing the product, the flip-down clamping frame 118 is manually rotated 90° to the side to be in the open state for product loading and unloading. By clamping the two ends of the product along the X-axis with the flip-clamping components, the stability of the product during rotation and processing is effectively enhanced.
[0022] Preferably, protruding support blocks 111 are provided at the working positions of the rotary pressing cylinder 116 and the flipping pressing frame 118. These protruding support blocks 111 are located directly below the stress point of the product. When the rotary pressing cylinder 116 or the telescopic cylinder 119 on the flipping pressing frame 118 applies pressure, the protruding support blocks 111 support the stress area to prevent the product from being deformed or damaged due to excessive local stress, thus preventing product deformation and ensuring product quality and processing consistency.
[0023] like Figure 1 As shown, the sawing mechanism 2 includes two sets of sawing assemblies 21, which are arranged opposite each other along the X-axis and located at both ends of the X-axis of the loading mechanism 1; the milling mechanism 3 includes two sets of milling cutter assemblies 31, which are arranged opposite each other along the X-axis and located at both ends of the X-axis of the reference frame 11. The two sets of sawing assemblies 21 and the two sets of milling cutter assemblies 31 respectively process the two ends of the two products clamped on the reference frame 11.
[0024] like Figure 4 As shown, the saw assembly 21 includes a saw bracket 211, on which a first lifting module 212 (such as a servo lifting mechanism) is provided. The output end of the first lifting module 212 is provided with a saw unit. The saw unit includes a first saw unit 213 and a second saw unit 214 that are offset along the Z-axis direction to perform cutting processing in different directions, effectively improving processing efficiency.
[0025] like Figure 4As shown, the first saw unit 213 includes a first saw blade 2131, a first rotary drive component 2132 (such as a motor) for driving the first saw blade 2131 to rotate, and a first transverse movement module 2133 (such as a lead screw module or a servo motor module) for driving the first saw blade 2131 and the first rotary drive component 2132 to move laterally along the X-axis. The first saw blade 2131 cuts in the X-axis direction, suitable for transverse cutting of the product end face. The first transverse movement module allows the first saw blade to adjust its cutting position to adapt to different processing requirements.
[0026] The second saw unit 214 includes a second saw blade 2141, a second rotary drive component 2142 (such as a motor) for driving the second saw blade 2141 to rotate, and a second transverse movement module 2143 (such as a lead screw module or a servo motor module) for driving the second saw blade 2141 and the second rotary drive component 2142 to move laterally along the X-axis. The second saw blade 2141 cuts in the Y-axis direction, suitable for longitudinal cutting of the side of a product.
[0027] The first saw blade 2131 and the second saw blade 2141 are respectively adjusted in position by the first transverse module 2133 and the second transverse module 2143, which can realize synchronous processing or individual processing to meet the processing requirements of multi-directional cutting and effectively improve the processing flexibility and accuracy.
[0028] like Figure 5 As shown, the milling cutter assembly 31 includes a milling cutter unit 311 and a third transverse module 312 for driving the milling cutter unit 311 to move laterally in the X direction, a fourth transverse module 313 for moving laterally in the Y direction, and a second lifting module 314 for lifting and lowering in the Z direction. The milling cutter unit 311 includes a milling cutter 3111 and a third rotary drive component 3112 for driving the milling cutter 3111. Through the third transverse module 312 and the fourth transverse module 313, the milling cutter 3111 can move flexibly in the X and Y directions. Combined with the Z-axis movement of the second lifting module 314, three-axis linkage milling is achieved. The machining position can be flexibly adjusted according to actual needs, effectively improving machining accuracy.
