Description

Technical Field

[0001] This utility model belongs to the field of titanium rod processing technology, and in particular relates to the feeding and positioning mechanism of an automatic feeding saw for titanium rods. Background Technology

[0002] Titanium bars are widely used in aerospace, medical, and chemical industries due to their high strength, corrosion resistance, and lightweight properties. During the sawing process of titanium bars, precise feeding and positioning of the bar stock are necessary to ensure dimensional accuracy and end-face quality. Currently, most sawing machines still use manual feeding and positioning, which is labor-intensive, inefficient, and prone to positioning errors, affecting processing consistency. Some automated equipment uses cylinders or hydraulic clamping, but these are complex in structure, slow in response, and can easily cause damage to the titanium bar surface.

[0003] The existing titanium rod feeding mechanism still has the following problems during use: First, the feeding positioning accuracy is insufficient, resulting in inconsistent sawing lengths; second, the clamping mechanism is inconvenient to adjust and difficult to adapt to titanium rods of different diameters; third, the degree of automation is low, relying on manual operation, which limits production efficiency.

[0004] To address these issues, we provide a feeding and positioning mechanism for an automatic titanium bar feeding saw. Utility Model Content

[0005] The purpose of this invention is to provide a feeding and positioning mechanism for an automatic feeding saw for titanium bars. By combining the gap drive mechanism and the clamping mechanism, the invention solves the problems of poor clamping adaptability and insufficient automation in the feeding and positioning mechanisms of existing automatic feeding saws for titanium bars.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a feeding and positioning mechanism for an automatic feeding saw for titanium bars, comprising a worktable, with a housing fixedly connected to one side of the worktable; a gap drive mechanism is provided on one side of the housing, the gap drive mechanism including a mounting plate fixedly connected to one side of the housing, a drive motor fixedly connected to one side of the mounting plate, a half gear fixedly connected to the output shaft of the drive motor, and a first gear meshing with the surface of the half gear; a clamping mechanism is provided in the inner cavity of the housing, the clamping mechanism including a worm gear ring rotatably connected to the inner cavity of the housing through a bearing seat, a fixed ring disposed on the inner side of the worm gear ring, a through hole disposed on the surface of the fixed ring, and a clamping block disposed in the inner cavity of the through hole.

[0008] The present invention is further configured such that a rotating shaft is fixedly connected to the shaft of the first gear, and one end of the rotating shaft is rotatably connected to one side of the mounting plate through a bearing seat. The drive motor drives the half gear to rotate, and only some teeth of the half gear mesh with the first gear to realize the intermittent rotation of the first gear. The rotating shaft acts as a power transition component to convert the intermittent rotation of the first gear into the intermittent rotation of the turntable.

[0009] The present invention is further configured such that a turntable is fixedly connected to the other end of the rotating shaft, a guide post is fixedly connected to the surface of the turntable, and a sliding frame is slidably connected to the surface of the guide post. When the turntable rotates intermittently with the rotating shaft, the guide post fixed on the surface makes a circular motion synchronously. The sliding cooperation between the guide post and the sliding frame forces the sliding frame to make a linear motion along the axial direction of the guide post, thereby outputting intermittent linear power.

[0010] The present invention is further configured such that a toothed plate is slidably connected to one side of the chassis, a second gear is meshed on one side of the toothed plate, and a worm is fixedly connected to the shaft of the second gear. When the sliding frame moves forward, it pushes the toothed plate to slide along the side of the chassis, the toothed plate meshes with the second gear, and drives the second gear to rotate. The second gear is coaxially fixed with the worm, thereby driving the worm to rotate and realizing the motion conversion from linear to rotational.

[0011] The present invention is further configured such that a driving block is fixedly connected to one side of the clamping block, and a driving wheel is fixedly connected to the inner side of the worm gear ring. When the worm drives the worm gear ring to rotate, the driving wheels evenly distributed on the inner side of the worm gear ring rotate synchronously. When the driving wheel contacts the driving block on the clamping block, it pushes the clamping block to move towards the center of the fixed ring and clamps the titanium rod. The number of driving wheels is consistent with the number of clamping blocks to ensure that the clamping force is evenly distributed and to avoid deformation of the titanium rod.

[0012] The present invention is further configured such that a spring is sleeved on the surface of the clamping block, and the clamping block is reset to the outside under the elastic force of the spring, releasing the titanium rod and reserving space for the next feeding.

[0013] The present invention is further configured such that electric push rods are fixedly connected to both sides of the workbench, and a feeding block is fixedly connected to the output end of the electric push rod.

[0014] The present invention is further configured such that a material box is fixedly connected to the top of the workbench, and a control panel is fixedly connected to one side of the machine box. The control panel controls the extension and retraction of the electric push rod, and the feeding block moves with the output end of the electric push rod, pushing the titanium rod at the bottom of the material box along the top surface of the workbench to the center of the fixed ring, thus completing the feeding and positioning.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model converts the continuous rotation of the drive motor into intermittent output through the meshing transmission of the half gear and the first gear. Then, through the turntable, guide post and sliding frame mechanism, it is converted into the precise linear reciprocating motion of the toothed plate. Finally, the start and stop rhythm of the clamping mechanism is controlled by the combination of worm and worm wheel ring. This mechanical intermittent drive method can achieve high synchronization with the sawing process without the need for a complex electrical control system, effectively avoiding positioning errors and equipment idling, and improving the feeding positioning accuracy and production efficiency.

[0017] 2. This utility model achieves multi-point uniform clamping of titanium rods by having multiple clamping blocks evenly distributed around the fixed ring work together and synchronously contract radially under the push of the drive wheel inside the worm gear ring. This design significantly increases the clamping contact area, avoids stress concentration, effectively prevents pressure damage or scratches on the surface of the titanium rod, ensures clamping stability and the quality of the finished material, and the clamping blocks can automatically reset under the action of springs, providing convenience for continuous feeding.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Please see Figures 1-5 This utility model is a feeding and positioning mechanism for an automatic feeding saw for titanium rods, including a worktable 1, with a housing 2 fixedly connected to one side of the worktable 1; a gap drive mechanism is provided on one side of the housing 2, the gap drive mechanism includes a mounting plate 3 fixedly connected to one side of the housing 2, a drive motor 4 fixedly connected to one side of the mounting plate 3, a half gear 5 fixedly connected to the output shaft of the drive motor 4, and a first gear 6 meshing with the surface of the half gear 5; a clamping mechanism is provided in the inner cavity of the housing 2, the clamping mechanism includes a worm gear ring 7 rotatably connected to the inner cavity of the housing 2 through a bearing seat, a fixed ring 8 provided inside the worm gear ring 7, a through hole 9 provided on the surface of the fixed ring 8, and a clamping block 10 provided in the inner cavity of the through hole 9.

[0029] Further details: The worm gear ring 7 is rotatably connected to the inner wall of the housing 2 via bearings, the fixed ring 8 is fixed to the housing 2, and multiple sets of clamping blocks 10 are provided, evenly distributed circumferentially on the fixed ring 8 to achieve multi-point synchronous clamping. The gap drive mechanism achieves intermittent motion through the meshing of the half gear 5 and the first gear 6, driving the worm gear ring 7 to rotate in an indexing manner. The clamping mechanism pushes the clamping blocks 10 to achieve radial clamping through the drive wheel 19 inside the worm gear ring 7. The feeding mechanism pushes the feeding block 22 through the electric push rod 21 to achieve automatic feeding and alignment of titanium rods.

[0030] Example 2

[0031] Please see Figures 1-5 Based on embodiment 1, a rotating shaft 11 is fixedly connected to the shaft center of the first gear 6. One end of the rotating shaft 11 is rotatably connected to one side of the mounting plate 3 through a bearing seat. A turntable 12 is fixedly connected to the other end of the rotating shaft 11. A guide post 13 is fixedly connected to the surface of the turntable 12. A sliding frame 14 is slidably connected to the surface of the guide post 13. A toothed plate 15 is slidably connected to one side of the machine housing 2. A second gear 16 meshes with one side of the toothed plate 15. A worm gear 17 is fixedly connected to the shaft center of the second gear 16. A drive block 18 is fixedly connected to one side of the clamping block 10. A drive wheel 19 is fixedly connected to the inner side of the worm gear ring 7. A spring 20 is sleeved on the surface of the clamping block 10. Electric push rods 21 are fixedly connected to both sides of the worktable 1. A feeding block 22 is fixedly connected to the output end of the electric push rod 21. A material box 23 is fixedly connected to the top of the worktable 1. A control panel 24 is fixedly connected to one side of the machine housing 2.

[0032] Further explanation: The drive motor 4 drives the half gear 5 to rotate. Only some teeth of the half gear 5 mesh with the first gear 6, realizing the intermittent rotation of the first gear 6. The rotating shaft 11 acts as a power transition component, converting the intermittent rotation of the first gear 6 into the intermittent rotation of the turntable 12. When the turntable 12 rotates intermittently with the rotating shaft 11, the guide post 13 fixed on the surface moves in a circular motion synchronously. The sliding engagement between the guide post 13 and the sliding frame 14 forces the sliding frame 14 to move linearly along the axial direction of the guide post 13, thereby outputting intermittent linear power. When the sliding frame 14 moves forward, it pushes the toothed plate 15 to slide along the side of the housing 2. The toothed plate 15 meshes with the second gear 16, driving the second gear 16 to rotate. The second gear 16 is coaxially fixed with the worm gear 17, thereby driving the worm... The rotation of rod 17 realizes the conversion of linear motion to rotation. When the worm gear 17 drives the worm wheel ring 7 to rotate, the drive wheels 19 evenly distributed on the inner side of the worm wheel ring 7 rotate synchronously. When the drive wheels 19 contact the drive blocks 18 on the clamping block 10, they push the clamping block 10 to move towards the center of the fixed ring 8, clamping the titanium rod. The number of drive wheels 19 is consistent with the number of clamping blocks 10 to ensure that the clamping force is evenly distributed and to avoid deformation of the titanium rod. Under the elastic force of the spring 20, the clamping block 10 resets to the outside, releasing the titanium rod and reserving space for the next feeding. The control panel 24 controls the extension and retraction of the electric push rod 21. The feeding block 22 moves with the output end of the electric push rod 21, pushing the titanium rod at the bottom of the material box 23 along the top surface of the workbench 1 to the center of the fixed ring 8, completing the feeding and positioning.

[0033] The working principle of this utility model is as follows: the control panel 24 starts the electric push rod 21, and the feeding block 22 pushes the titanium rod in the material box 23 along the top surface of the worktable 1 to the center position of the fixing ring 8 to complete the feeding.

[0034] Control panel 24 starts drive motor 4, drive motor 4 drives half gear 5 to rotate. Since only some teeth of half gear 5 mesh with first gear 6, first gear 6 rotates intermittently (pausing once every half revolution). Through rotating shaft 11, it drives turntable 12 to rotate synchronously and intermittently. When turntable 12 rotates, surface guide post 13 pushes sliding frame 14 to move forward along the axis of guide post 13. Sliding frame 14 pushes tooth plate 15 to slide along the side of chassis 2. Tooth plate 15 meshes with second gear 16, driving second gear 16 and worm gear 17 to rotate.

[0035] The worm gear 17 drives the worm wheel ring 7 to rotate. The drive wheel 19 inside the worm wheel ring 7 rotates synchronously with the worm wheel ring 7. When the drive wheel 19 contacts the drive block 18 on the clamping block 10, it pushes the clamping block 10 to move towards the center of the fixed ring 8 and clamps the titanium rod.

[0036] Half gear 5 continues to rotate and disengages from the first gear 6. At this time, worm gear 17 stops driving worm wheel ring 7, which facilitates sawing. Then, half gear 5 drives worm gear 17 to rotate in the opposite direction through the first gear 6. Drive wheel 19 separates from drive block 18. Clamping block 10 returns to its original position outside under the elastic force of spring 20, releasing the titanium rod. Electric push rod 21 starts again, pushing a new titanium rod to the center of fixed ring 8. Drive motor 4 repeats the above actions to realize automatic feeding, positioning and clamping of titanium rod, and enter the next round of cutting.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
