Description

A positioning and locking mechanism for a band saw Technical Field

[0001] This utility model relates to the field of band saw technology, and in particular to a positioning and locking mechanism for a band saw. Background Technology

[0002] Band saws are widely used in industrial production as a common cutting equipment for metal or non-metal materials. When band saws are used for cutting operations, in order to ensure the accuracy, efficiency and safety of the cutting, it is necessary to reliably position and stably lock the workpiece being cut.

[0003] However, most existing band saws rely on pressure to fix the workpiece to the worktable surface for positioning and locking when locking the workpiece. While this method is effective for fixing the workpiece as a whole, near the cutting point, especially at the moment when the workpiece is about to be completely cut off, the material in the cut portion or cutting area may deform and vibrate due to stress release, gravity, or sawing stress. Since existing positioning and locking mechanisms usually only provide support and clamping in areas far from the cutting line, and lack effective and tight support or clamping near the critical cutting position, the final cut surface deviates, affecting the cutting accuracy.

[0004] Therefore, we propose a positioning and locking mechanism for band saws. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a positioning and locking mechanism for a band saw.

[0006] The positioning and locking mechanism for a band saw provided by this utility model includes: a base, a work plate, a cutting positioning mechanism, a cutting moving and pressing mechanism, and an edge positioning mechanism. The base is fixed on the cutting table of the band saw. The upper surface of the base is connected to the work plate via a moving mechanism. The upper surface of the work plate has a through cutting groove. The edge of the upper surface of the work plate is provided with a cutting positioning mechanism. The cutting positioning mechanism includes a positioning plate and a locking block. The upper surface of the work plate has two symmetrically distributed adjusting grooves. The lower surface of the positioning plate is fixedly connected to two sliders, which slide within the adjusting grooves. The upper surface of the positioning plate is threaded with a locking block for locking. The upper surface of the positioning plate is provided with two symmetrically distributed cutting moving and pressing mechanisms. Edge positioning mechanisms are provided on both sides of the work plate.

[0007] Preferably, the cutting and pressing mechanism includes a telescopic rod, a U-shaped plate, positioning rollers, a rotating rod, and a lifting rod. Two telescopic rods are fixedly connected to the upper surface of the positioning plate. A lifting rod is threadedly connected to the outer end of the upper surface of the telescopic rod. A rotating rod is fixedly connected to the top end of the lifting rod. The bottom end of the lifting rod passes through the inner wall of the telescopic rod and is rotatably connected to the U-shaped plate. Positioning rollers are rotatably connected between the inner walls of the two sides of the U-shaped plate.

[0008] Preferably, buffer grooves are provided on both sides of the U-shaped plate, and the upper and lower inner walls of the buffer grooves are connected by multiple evenly distributed springs.

[0009] Preferably, the moving mechanism includes a moving plate and a threaded rod. The upper surface of the base has two symmetrically distributed moving slots. The moving plate is slidably connected in the moving slots. The top end of the moving plate is fixedly connected to the working plate.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] Please refer to Figures 1 to 3. The positioning and locking mechanism of the band saw provided in this embodiment includes: a base 1, a working plate 6, a cutting positioning mechanism, a cutting moving pressing mechanism, and an edge positioning mechanism.

[0022] The base 1 is fixed on the cutting table of the band saw. The upper surface of the base 1 is connected to the work plate 6 via a moving mechanism. The moving mechanism includes a moving plate 3 and a threaded rod 5. Two symmetrically distributed moving grooves 2 are opened on the upper surface of the base 1. The moving plate 3 is slidably connected in the moving groove 2. The top of the moving plate 3 is fixedly connected to the work plate 6. The threaded rod 5 is rotatably connected between the inner walls of the two sides of the moving groove 2 on the right side. The threaded rod 5 passes through the moving plate 3 and is threadedly connected. The rear end face of the threaded rod 5 passes through the inner wall of the base 1 and is fixedly connected to the output end of the drive motor through a coupling. The drive motor is fixed to the rear end face of the base 1.

[0023] It should be noted that the device moves the working plate 6 by setting a moving mechanism on the base 1. During operation, the drive motor rotates, and the threaded rod 5 drives the moving plate 3 to move linearly along the moving groove 2, thereby pushing the working plate 6 and the workpiece to be cut placed on it to move. This allows the operator to easily and quickly adjust the cutting position of the workpiece relative to the saw blade by simply driving the moving mechanism, which greatly improves the convenience and efficiency of the cutting operation.

[0024] The upper surface of the work plate 6 has a through cutting groove 8. The edge of the upper surface of the work plate 6 is provided with a cutting positioning mechanism, which includes a positioning plate 9 and a locking block 10. The upper surface of the work plate 6 has two symmetrically distributed adjustment grooves 7. The lower surface of the positioning plate 9 is fixedly connected to two sliders, which slide within the adjustment grooves 7. The upper surface of the positioning plate 9 is threaded with a locking block 10 for locking.

[0025] It should be noted that the positioning plate 9 is slidably connected to the slider in the adjustment groove 7 on the working plate 6 through its lower surface, so that its position can be adjusted in the adjustment groove 7. After adjusting to the desired position, tightening the locking block 10 on the upper surface of the positioning plate 9 can reliably fix the positioning plate 9. In use, the workpiece to be cut rests against one side of the positioning plate 9. As a stable support, the positioning plate 9 can effectively limit the shaking and displacement of the workpiece during the cutting process, enhance the stability of the workpiece, and thus improve the final cutting accuracy.

[0026] The upper surface of the positioning plate 9 is provided with two symmetrically distributed cutting and pressing mechanisms. The cutting and pressing mechanisms include telescopic rods 15, U-shaped plates 16, positioning rollers 19, rotating rods 17, and lifting rods 18. Two telescopic rods 15 are fixedly connected to the upper surface of the positioning plate 9. The outer end of the upper surface of the telescopic rods 15 is threadedly connected to the lifting rods 18. The top end of the lifting rods 18 is fixedly connected to the rotating rods 17. The bottom end of the lifting rods 18 passes through the inner wall of the telescopic rods 15 and is rotatably connected to the U-shaped plates 16. The positioning rollers 19 are rotatably connected between the inner walls of the two sides of the U-shaped plates 16. Buffer grooves are opened on both sides of the U-shaped plates 16. The upper and lower inner walls of the buffer grooves are connected by multiple evenly distributed springs 20.

[0027] It should be noted that, in order to apply stable pressure to the workpiece at the critical cutting position (near the cutting groove 8) and effectively suppress deformation, this mechanism has two cutting movement and pressing mechanisms symmetrically arranged on the upper surface of the positioning plate 9. The lifting rod 18, which moves up and down within the telescopic rod 15, is adjusted by turning the rotating rod 17. The bottom end of the lifting rod 18 is rotatably connected to a U-shaped plate 16, and positioning rollers 19 are rotatably connected between the inner walls on both sides of the U-shaped plate 16 for directly contacting and pressing the upper surface of the workpiece. In addition, springs 20 are provided in the buffer grooves on both sides of the U-shaped plate 16. By turning the rotating rod 17 to adjust the height of the positioning rollers 19, they apply downward pressing force to the workpiece. Combined with the elastic buffer provided by the springs 20, the positioning rollers 19 can tightly and gently press the workpiece in the area on both sides of the cutting position, effectively reducing the deformation, jumping or lifting of the workpiece caused by stress during sawing, significantly improving the cutting accuracy and stability, and protecting the surface of the workpiece.

[0028] Both sides of the working plate 6 are provided with edge positioning mechanisms. The edge positioning mechanisms include an adjusting plate 4, an L-shaped plate 11, a rotating plate 12, and an adjusting rod 13. The adjusting plate 4 is slidably connected to both sides of the working plate 6. The outer side of the adjusting plate 4 is threaded with a locking block. The top of the adjusting plate 4 is fixedly connected to the L-shaped plate 11. The lower surface of the L-shaped plate 11 is rotatably connected to the rotating plate 12. The upper surface of the rotating plate 12 is threadedly connected to the adjusting rod 13. The top of the adjusting rod 13 is fixedly connected to a locking block. The bottom end of the adjusting rod 13 is provided through the inner wall of the rotating plate 12. The bottom end of the adjusting rod 13 is rotatably connected to an anti-slip pad 14.

[0029] It should be noted that, in order to enhance the overall stability of the workpiece during the cutting process, the mechanism is equipped with edge positioning mechanisms on both sides of the working plate 6. In use, the overall lateral position of the mechanism is first set and locked by adjusting plate 4. Then, rotate rotating plate 12 to position adjusting rod 13 and anti-slip pad 14 above the workpiece. Then, rotate adjusting rod 13 to press down on the upper surface of the workpiece through anti-slip pad 14. The edge positioning mechanisms on both sides work together to apply pressure to the workpiece, which can effectively limit the lateral movement, warping or tilting of the workpiece during the cutting process, improve the safety and stability of cutting. At the same time, anti-slip pad 14 avoids hard damage to the surface of the workpiece.

[0030] In summary, this utility model embodiment provides a positioning and locking mechanism for a band saw, which achieves precise, stable, and convenient positioning of the workpiece and multi-point coordinated clamping.

[0031] The moving mechanism uses a drive motor to drive the threaded rod 5 to slide the moving plate 3 in the moving groove 2 of the base 1, thereby facilitating the movement of the work plate 6. This allows the operator to quickly adjust the cutting position without moving the workpiece, improving efficiency.

[0032] A cutting and positioning mechanism is provided on the upper surface of the work plate 6. The workpiece rests against the positioning plate 9, which can effectively limit shaking and displacement and improve the initial positioning accuracy.

[0033] Furthermore, a cutting movement clamping mechanism is symmetrically arranged on the positioning plate 9. By adjusting the height of the lifting rod 18, the positioning roller 19 with spring 20 buffer can apply an adjustable and gentle clamping force to the workpiece on both sides of the cutting position, effectively preventing deformation and lifting during cutting, and significantly improving the stability and accuracy of cutting.

[0034] In addition, edge positioning mechanisms are provided on both sides of the work plate 6. The lateral position is adjusted by adjusting the plate 4, rotating the rotating plate 12 and adjusting the height of the adjusting rod 13, so that the anti-slip pad 14 presses against the upper surface of the workpiece edge. The two mechanisms work together to enhance the overall stability of the workpiece and prevent warping and tilting. The anti-slip pad 14 also protects the surface of the workpiece.

[0035] By combining the functions of these mechanisms, this positioning and locking mechanism effectively solves the problems of inaccurate positioning, easy shaking, and easy deformation of the cutting position in the existing technology, thereby improving the cutting quality, ease of operation, and safety of the band saw.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
