[0023] Please see Figures 1 to 3 The present invention provides a manual reciprocating sawing fixture for sprue cutting, comprising a large support plate 10 mounted on a sawing machine, an X-axis slide rail 20 mounted on the large support plate 10, a middle support plate 30 slidably mounted on the X-axis slide rail 20, a Z-axis slide rail 40 mounted on the middle support plate 30, a small support plate 50 slidably mounted on the Z-axis slide rail 40, a fixing component 60 mounted on the small support plate 50 for fixing the workpiece 100, and an operating component 70 mounted on the small support plate 50.

[0024] The working principle of this utility model's manual reciprocating sawing fixture for sprues is as follows: Based on the size of the workpiece 100 and the sawing requirements, adjust the position of the workpiece 100 in the X and Z axes. In the X-axis direction, the worker can manually push the middle support plate 30 to slide on the X-axis slide rail 20. When the sawing position needs to be close to the edge of the workpiece 100, move the middle support plate 30 in the corresponding direction. In the Z-axis direction, for adjusting the position of the small support plate 50, the worker can use the Z-axis slide rail 40 to move the small support plate 50 up and down. The worker holds the handle on the operating component 70 and starts... The manual reciprocating saw is operated; the mechanical structure within the operating component 70 converts the reciprocating motion of the worker's arm into the reciprocating sawing motion of the saw blade; the saw blade begins to cut at the sprue of the workpiece 100; during the sawing process, the worker needs to adjust the force appropriately according to the sawing resistance of the saw blade; at the same time, since the workpiece 100 has been fixed, the saw blade can accurately cut off the sprue along the predetermined position; when the saw blade has completely cut off the sprue, the worker stops operating the manual reciprocating saw; then, the fixing component 60 is released, and the workpiece 100 with the sprue cut off is removed from the fixing device.

[0025] Compared to existing technologies, this utility model's manual reciprocating sprue sawing fixture allows for precise position adjustment of the workpiece 100 via the X-axis slide rail 20 and Z-axis slide rail 40. In the X-axis direction, the workpiece 100 can be accurately positioned at the sawing start point, and the fixing component 60 firmly secures the workpiece 100, preventing displacement or vibration during sawing and improving processing stability. Because its position can be flexibly adjusted in both the X and Z axes, this fixture can adapt to workpieces 100 of different sizes and shapes. Whether for large industrial castings or small injection-molded parts, this fixture can be used for sprue sawing. Using a manual reciprocating saw as the operating component 70, the operator can flexibly control the sawing speed and force according to the actual sawing situation. During sawing, the operator can feel the resistance of the saw blade in real time, and can adjust the operation promptly when encountering uneven material or complex sprue structures. When sawing plastic sprues containing impurities, the operator can slow down the sawing speed to avoid damaging the saw blade. This flexibility of manual operation is difficult for automated sawing equipment to completely replace.

[0026] Please see Figure 1 and Figure 2 The fixing component 60 includes a positioning element 61 mounted on the small tray 50 for placing the workpiece 100, and a fixing element 62 mounted on the small tray 50 for fixing the workpiece 100 to the positioning element 61. The positioning element 61 ensures that the workpiece 100 is in an accurate position on the small tray 50, providing a precise starting position for subsequent sawing operations. For example, when sawing an injection molded part with multiple sprues and high positional accuracy requirements, the positioning element 61 can ensure that the workpiece 100 is placed in the same position each time. In this way, when the saw blade cuts the sprues, it can follow a preset path, reducing the deviation of the sawing position, thereby ensuring the stable sawing quality of each workpiece 100 and improving product consistency. For workpieces 100 with regular shapes, such as square or round mechanical parts, the positioning element 61 can have corresponding grooves or protrusions to fix the workpiece 100. It can be precisely positioned; for irregularly shaped workpieces 100, the positioning member 61 can achieve positioning by matching the shape of the workpiece 100; the fixing member 62 firmly fixes the workpiece 100 to the positioning member 61 by applying pressure or clamping force, which can effectively prevent the workpiece 100 from shifting, vibrating or jumping during the sawing process; when sawing some workpieces 100 with hard materials or large sawing force, such as the sprue of metal castings, the stable position of the workpiece 100 can ensure the accuracy of the saw blade's direction when sawing, reduce the saw blade's deviation and wear, extend the service life of the saw blade, and also improve the flatness of the sawing surface.

[0027] The positioning component 61 includes a mounting part mounted on the small pallet 50 for placing the workpiece 100, and a positioning part mounted on the small pallet 50 for positioning the workpiece 100 on the mounting part. The mounting part, as the basic structure for placing the workpiece 100, provides a stable placement plane for the workpiece 100. For example, for some heavier workpieces 100 or those with irregular bottom shapes, the mounting part ensures that the workpiece 100 has a flat and stable placement position on the small pallet 50, preventing the workpiece 100 from shaking or tilting due to unstable placement. During the sawing process, the mounting part can be optimized according to the shape of the bottom of the workpiece 100. If the bottom of the workpiece 100 is flat, the mounting part can be a simple flat plate structure; if the bottom of the workpiece 100 is curved or has a special contour, the mounting part can be made with a structure with corresponding grooves or protrusions, allowing the workpiece 100 to fit better. This ensures that workpieces 100 of different shapes can find a suitable placement method on the mounting part.

[0028] The mounting section includes a mounting platform 610 mounted on a small pallet 50, two mounting cavities 611 on the mounting platform 610 for placing the workpiece 100, and a connecting cavity 612 on the mounting platform 610 connected to the mounting cavities 611 on both sides. The mounting platform 610, as the basic structure of the mounting section, provides stable support for the entire mounting section. Mounted on the small pallet 50, it evenly transmits the force on the workpiece 100 placed in the mounting cavity 611 to the small pallet 50. During sawing, the sawing force applied to the workpiece 100 by the saw blade causes vibration and reaction force; the mounting platform 610 effectively disperses these forces, preventing displacement or damage to the workpiece 100 due to excessive local stress. For example, when sawing a large metal workpiece 100, the stable support of the mounting platform 610 ensures that the workpiece 100 remains stable under the sawing force. The mounting cavities 611 and connecting cavity 612 are located on the mounting platform 610, facilitating the mounting of the entire section on the small pallet. The mounting platform 610 on the small tray 50 allows for adjustment of the position of the workpiece 100 relative to the saw blade, adapting to different sawing requirements. Furthermore, during tooling assembly, the mounting platform 610 can be installed and debugged as an independent module, improving assembly efficiency. Two mounting cavities 611 allow for simultaneous placement of two workpieces 100, enabling batch processing. During production, while one workpiece 100 is being sawed, the worker can place the next workpiece 100 in the other mounting cavity 611. Once the current workpiece 100 is sawn, the next workpiece 100 can be sawed immediately, reducing the time interval for changing workpieces 100 and significantly improving work efficiency.

[0029] The positioning part includes a support column 613 mounted on the small pallet 50, a connecting arm 614 mounted on the support column 613 at one end and on the connecting cavity 612 at the other end, and positioning rings 615 extending from both sides of the connecting arm 614 toward the mounting cavity 611 and sleeved on the workpiece 100. The support column 613 is mounted on the small support plate 50, providing a stable support point for the connecting arm 614. During the sawing process, when the saw blade applies a sawing force to the workpiece 100, this force is transmitted to the support column 613 through the connecting arm 614. Due to the good stability of the support column 613, it can withstand these forces without deformation or displacement, thus ensuring the structural stability of the entire positioning part. One end of the connecting arm 614 is connected to the support column 613, and the other end is connected to the connecting cavity 612, acting as a bridge. It can transmit the supporting force of the support column 613 to the connecting cavity 612, ensuring that the connecting cavity 612 remains stable during the sawing process. At the same time, the connecting arm 614 also transmits the reaction force generated by the workpiece 100 during the sawing process back to the support column 613, keeping the entire system in a balanced state. For example, when... When the saw blade cuts the workpiece 100, the vibration and reaction force of the workpiece 100 are transmitted to the connecting arm 614 through the positioning ring 615, and then to the support column 613 through the connecting arm 614, ensuring that the workpiece 100 can withstand various forces brought about by the sawing operation in the positioning state. The positioning ring 615 extends from both sides of the connecting arm 614 to the mounting cavity 611 and fits on the workpiece 100, which can accurately determine the position of the workpiece 100 in the mounting cavity 611. This fitting method can limit the movement of the workpiece 100 in the horizontal direction (X-axis and Y-axis) and ensure that the workpiece 100 will not deviate during the sawing process. For example, when sawing the sprue of small precision parts, the positioning ring 615 can accurately position the workpiece 100 in the mounting cavity 611, so that the saw blade can accurately saw the sprue and improve the sawing accuracy.

[0030] The positioning part also includes a positioning post 616 mounted on the connecting arm 614; the fixing part 62 includes a fixing part 617 mounted on the small pallet 50, and a snap-fit ​​part 618 mounted on the fixing part 617 for fixing the positioning post 616. The positioning post 616 is mounted on the connecting arm 614 and cooperates with the positioning ring 615 to position the workpiece 100 from more dimensions; when the positioning ring 615 restricts the movement of the workpiece 100 in the horizontal direction, the positioning post 616 can further restrict the displacement of the workpiece 100 in the vertical direction or other specific directions, thereby achieving more precise positioning, ensuring the accurate relative position of the saw blade and the workpiece 100 during sawing, and improving sawing quality and accuracy; the fixing part 617 is mounted on the small pallet 50, providing a stable mounting base for the snap-fit ​​part 618; the snap-fit ​​part 618 can be firmly fixed on the small pallet 50, ensuring The snap-fit ​​part 618 will not loosen or shift due to force when fixing the positioning post 616, thus ensuring the fixing effect of the fastener 62. The snap-fit ​​part 618 is used to fix the positioning post 616 and usually has the characteristics of simple structure and convenient operation. When installing the workpiece 100, simply insert the positioning post 616 into the snap-fit ​​part 618 or use a simple operation to make the snap-fit ​​part 618 lock the positioning post 616 to achieve quick fixing, which greatly improves the installation efficiency of the workpiece 100. After sawing, the snap-fit ​​part 618 can also be easily released to remove the workpiece 100, reducing downtime and improving production efficiency.

[0031] There are two mounting sections, arranged side-by-side along the X-axis slide rail 20. This allows for the simultaneous processing of multiple workpieces 100, especially those with similar manufacturing processes and dimensions. Workpieces 100 can be placed on both mounting sections simultaneously and then sawn sequentially, enabling the processing of more workpieces 100 at a time. This is suitable for large-scale production scenarios and effectively improves batch production capabilities.

[0032] There are two connecting arms 614 and two positioning posts 616 in the positioning part, and four positioning rings 615. The two connecting arms 614 are respectively set in the two mounting parts, and the four positioning rings 615 are respectively set in the mounting cavities 611 on both sides of the connecting arms 614. The arrangement of two connecting arms 614 and four positioning rings 615 allows for positioning of the workpiece 100 from multiple directions. The connecting arms 614 restrict the displacement of the workpiece 100 in the extension direction of the connecting arms 614, while the four positioning rings 615 are respectively fitted onto different parts of the workpiece 100, accurately constraining the position of the workpiece 100 within the mounting cavity 611, including the horizontal direction (X, Y axes) and a certain degree of the vertical direction (Z axis), ensuring that the workpiece 100 does not shift during sawing, greatly improving sawing accuracy. For workpieces 100 of various shapes, whether regular circles, squares, or irregular shapes, the combination of four positioning rings 615 and two connecting arms 614 can provide effective positioning. The positioning rings 615 can flexibly fit onto the appropriate position of the workpiece 100 according to its contour shape, while the connecting arms 614 can assist in fixing the posture of the workpiece 100, ensuring that workpieces 100 of different shapes can be accurately positioned within the mounting cavity 611, enhancing the adaptability of the tooling to different workpiece shapes.

[0033] Please refer to Figure 2 and Figure 3 The manual reciprocating sprue sawing fixture also includes X-axis limiting blocks 80 located at both ends of the large support plate 10 to prevent the middle support plate 30 from detaching from the X-axis slide rail 20. During the use of the fixture, the middle support plate 30 slides along the X-axis slide rail 20 to adjust the position of the workpiece 100 in the X-axis direction. Without the X-axis limiting blocks 80, the middle support plate 30 may detach from the X-axis slide rail 20 in the event of operational errors (such as excessive sliding speed or excessive force) or mechanical failures (such as excessive lubrication of the slide rail resulting in insufficient friction). The X-axis limiting blocks 80 effectively prevent this from happening, preventing the middle support plate 30 and its components (including the workpiece 100, the small support plate 50, etc.) from accidentally falling off, thereby ensuring the personal safety of the operator and avoiding accidents such as injuries caused by falling components. The X-axis limiting blocks 80 can maintain the integrity of the fixture system, ensuring that the sprue sawing operation can be carried out in a stable and predictable environment, reducing the interference of unexpected situations on the production order.

[0034] The manual reciprocating sprue saw also includes Z-axis limiting blocks 90 located at both ends of the middle support plate 30 to prevent the small support plate 50 from detaching from the Z-axis slide rail 40. During the operation of the sprue saw, the small support plate 50 slides on the Z-axis slide rail 40 to adjust the vertical position of the workpiece 100. Without the Z-axis limiting blocks 90, due to operational errors (such as excessive pushing of the small support plate 50), mechanical failure, or vibration, the small support plate 50 may detach from the Z-axis slide rail 40. This could cause the small support plate 50, the workpiece 100, and the operating components 70 to fall, resulting in serious personal injury to the operator. The presence of the Z-axis limiting blocks 90 acts as a safety barrier, effectively preventing the small support plate 50 from detaching from the slide rail, thereby ensuring the safety of the operator.

[0035] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
