Description

Technical Field

[0001] This utility model relates to the field of sawing tool processing technology, specifically a saw tooth feeding mechanism. Background Technology

[0002] In the saw blade welding process, the long saw blade must first be accurately fed to the welding station to ensure that the area to be welded on the saw blade is aligned with the welding head and the saw tooth positioning components of the welding equipment before the subsequent welding of individual saw teeth can be carried out. The accuracy and stability of the saw blade feeding directly determine the accuracy of the welding tooth position and the final quality of the saw blade product.

[0003] Currently, most mainstream saw blade welding equipment in the industry relies on manual operation to remove the saw blade from the clamping station after welding. Operators must manually remove the saw blade from the station after the clamping mechanism is released before inserting the next blade to be welded. This manual method is not only inefficient, but also poses a risk of burns due to residual welding heat near the welding station, as operators are prone to contact with high-temperature components during manual removal. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a sawtooth feeding mechanism to solve the problems of cumbersome operation and low safety of conventional sawtooth welding feeding mechanisms mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sawtooth feeding mechanism, including a linear slide and a base, and a clamping plate assembly. The clamping plate assembly includes a cylinder fixedly installed above the base, an upper clamping plate connected to the output end of the cylinder, and a lower clamping plate fixed relative to the base and correspondingly arranged above and below the upper clamping plate. A pair of swing arms are rotatably installed above the lower clamping plate. An elastic member connects the swing arms and the lower clamping plate. The upper clamping plate can be driven by the cylinder to move closer to or away from the lower clamping plate to achieve the clamping or loosening of the sawtooth. Under the elastic force of the elastic member, the swing arms exert a pushing force on the sawtooth after loosening, so as to realize the feeding action of the sawtooth.

[0006] Preferably, the top of the lower clamping plate is provided with a clearance groove, in which a pair of rotating shafts and a pair of protruding posts are fixedly installed respectively, and a pair of swing arms are rotatably installed on the rotating shafts respectively, and the elastic member is connected to the protruding posts.

[0007] Preferably, the elastic member is a torsion spring sleeved on the protruding post, and a protrusion is provided on one side of the top of the lower clamping plate. The two ends of the torsion spring abut against the swing arm and the protrusion, respectively.

[0008] Preferably, one side of the swing arm is provided with a sliding hole for accommodating the torsion spring.

[0009] Preferably, the side of the swing arm is provided with an L-shaped groove for accommodating the saw teeth.

[0010] Preferably, the corners of the swing arm are rounded for a smooth transition.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The clamping plate assembly of this utility model, through the cooperation of a swing arm and a torsion spring, can automatically push the saw teeth to release them after the saw teeth have been clamped and positioned and processed by the elastic force of the torsion spring. This not only ensures the reliability of the saw teeth being stably clamped during processing, but also completes the feeding action through the elastic potential energy of the torsion spring. No additional drive components are required, the structure is simple and the operation is convenient, and it effectively improves the continuity of saw tooth feeding and the safety of operation.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-4This utility model provides a technical solution: a sawtooth feeding mechanism, including a linear slide 1 and a base 2, and a clamping plate assembly. The clamping plate assembly includes a cylinder 3 fixedly installed above the base 2, an upper clamping plate 4 connected to the output end of the cylinder 3, and a lower clamping plate 5 fixed relative to the base 2 and correspondingly arranged above the upper clamping plate 4. A pair of swing arms 6 are rotatably installed above the lower clamping plate 5. An elastic member connects the swing arms 6 and the lower clamping plate 5. The upper clamping plate 4 can be driven by the cylinder 3 to move closer to or away from the lower clamping plate 5 to clamp or release the sawtooth. The corresponding arrangement of the upper and lower clamping plates ensures that the sawtooth is subjected to uniform force when clamped, avoiding deformation of the sawtooth due to unilateral force, and is especially suitable for thin or easily deformable sawtooth materials. The sides of the swing arms 6 are provided with L-shaped grooves for accommodating the sawtooth. The corners of the swing arms 6 are all rounded and smooth transitions. The rounded corner transitions can reduce the contact wear between the sawtooth and the swing arms 6, and at the same time avoid the sawtooth edges from burrs due to impact, thus protecting the material processing quality. The swing arm 6, under the elastic force of the elastic component, exerts a pushing force on the saw teeth after it is released, so as to realize the feeding action of the saw teeth.

[0016] The lower clamping plate 5 has a clearance groove 8 at its top, in which a pair of rotating shafts and a pair of protruding columns are fixedly installed. A pair of swing arms 6 are rotatably mounted on the rotating shafts. The elastic component is connected to the protruding columns. The clearance groove 8 provides integrated installation space for the swing arms 6, rotating shafts, and elastic components, making the layout of each component compact and reducing the overall volume occupied by the mechanism. The rotating shafts provide a fixed rotation fulcrum for the swing arms 6, while the protruding columns act as radial limiters for the elastic components, preventing them from shifting or falling off when subjected to force, thus improving the stability of the mechanism. The elastic component is a torsion spring 7 sleeved on the protruding column. A protrusion 9 is provided on one side of the top of the lower clamping plate 5, and the height of the protrusion 9 is adapted to not interfere with the action of the upper and lower clamping plates clamping the saw teeth, ensuring the smoothness of the clamping process. The two ends of the torsion spring 7 abut against the swing arm 6 and the protrusion 9 respectively, which can continuously provide a stable restoring force for the swing arm 6, ensuring that the pushing force of the swing arm 6 is consistent after each release, and avoiding feeding jamming. A sliding hole 10 is provided on one side of the swing arm 6 to accommodate the torsion spring 7. The sliding hole 10 can accommodate the end of the torsion spring 7, preventing the torsion spring 7 from interfering with the swing arm 6 when it deforms. At the same time, it plays a guiding role in the extension and retraction trajectory of the torsion spring 7, extending the service life of the torsion spring 7.

[0017] Working principle: When cylinder 3 is in the extended state, it drives the upper clamping plate 4 away from the lower clamping plate 5, forming a gap between the upper and lower clamping plates for inserting the saw teeth. At this time, the swing arm 6 is in the initial reset position under the elastic force of the torsion spring 7, with its side L-shaped groove facing the feeding direction. The saw teeth to be conveyed are placed above the lower clamping plate 5, with both sides embedded in the L-shaped groove of the swing arm 6 (the L-shaped groove provides lateral restraint for the saw teeth). Then, cylinder 3 retracts, driving the upper clamping plate 4 downward towards the lower clamping plate 5 until the upper and lower clamping plates clamp and fix the saw teeth. Subsequently, the linear slide 1 starts, driving the linear slide 1 and the clamping plate assembly fixed on it, as well as the clamped saw teeth, to move linearly along a preset trajectory, conveying the saw teeth to the target processing or assembly position.

[0018] After the saw teeth are processed, they are transported to a position away from the processing station via the linear slide 1. The cylinder 3 extends again, the upper clamping plate 4 moves upward away from the lower clamping plate 5, the saw teeth are released from the clamping state, and the swing arm 6 rotates around the axis in the feeding direction under the elastic release of the torsion spring 7, pushing the saw teeth out from between the upper and lower clamping plates, thus completing the feeding action.

[0019] The saw tooth processing clamping assembly of this application, through the cooperation of the swing arm 6 and the torsion spring 7, after the saw tooth has been clamped and positioned and processed, can automatically push the swing arm 6 to release the saw tooth by the elastic force of the torsion spring 7. This not only ensures the reliability of the saw tooth being stably clamped during the processing, but also completes the feeding action by the elastic potential energy of the torsion spring 7. No additional drive components are required. The structure is simple and the operation is convenient, effectively improving the automation level and work efficiency of saw tooth feeding.
