Description

Technical Field

[0001] This utility model belongs to the field of bucket shaft processing technology, specifically a positioning mechanism for bucket shaft processing. Background Technology

[0002] The bucket shaft, also known as a pin or connecting shaft, is a key basic component in the working device of construction machinery (such as excavators and loaders). It typically runs through components such as bucket teeth, bucket, connecting rod, and rocker arm, serving as a core connecting part and force-bearing point. During the manufacturing process of the bucket shaft, a positioning mechanism is required to fix it in place.

[0003] For example, the utility model patent with announcement number CN217020047U discloses a transmission shaft machining positioning fixture. This transmission shaft machining positioning fixture can realize the centering and clamping function of the transmission shaft to facilitate the subsequent transmission shaft machining work. It can also adjust the orientation angle of the transmission shaft to facilitate the machining work of the transmission shaft.

[0004] However, the aforementioned drive shaft machining positioning fixture uses multiple sets of positioning bolts for centering and clamping, which is cumbersome and inefficient. Moreover, when the lateral force on the shaft workpiece is greater than the friction between the workpiece and the positioning bolts, it is easy to cause displacement between the shaft workpiece and the positioning bolts, affecting the stability of clamping. In addition, after machining is completed, the machine needs to be stopped to wait for the shaft workpiece to be loaded and unloaded, which affects the machining efficiency. Utility Model Content

[0009] As a preferred embodiment of this utility model, a rotating groove is provided in the middle of the tightening disc, and a pressing disc is rotatably arranged inside the rotating groove, which facilitates pressing against the bucket shaft.

[0010] As a preferred technical solution of this utility model, a fixed tube is fixedly provided on all four sides of the inner wall of the clamping frame, and a telescopic tube is slidably provided inside the fixed tube. One end of the telescopic tube is fixedly connected to the tightening block. The fixed tube and the telescopic tube are used to limit the clamping block.

[0018] Please see Figures 1-6 This utility model discloses a positioning mechanism for bucket shaft processing, including a processing table 1, and a conversion servo motor 2 disposed on one side of the bottom surface of the processing table 1. A conversion frame 3 is fixedly disposed at the output end of the conversion servo motor 2. Three sets of positioning rails 4 are fixedly disposed in a circular array on the surface of the conversion frame 3. Through the setting of the conversion frame 3 and the positioning rails 4, a set of bucket shafts is installed on one set of positioning rails 4 for processing. During processing, a new bucket shaft is installed on other positioning rails 4. After processing is completed, the conversion servo motor 2 drives the conversion frame 3 to rotate, so that the positions of the bucket shafts on the three sets of positioning rails 4 are exchanged. The operator can remove the processed bucket shaft and install a new bucket shaft. At the same time, another set of bucket shafts is being processed. The processing and loading / unloading stations do not interfere with each other, reducing the waiting time for loading and unloading workpieces and improving processing efficiency. An adjustment component 5 is installed at one end of the positioning track 4. Two sets of clamping frames 6 are threadedly connected to the surface of the adjustment component 5. A positioning plate 7 is fixedly installed on the top of the clamping frame 6. A tightening component 8 is installed on one side of the positioning plate 7. Tightening channels are opened around the surface of the tightening component 8. Tightening blocks 9 are slidably installed inside the tightening channels. With the adjustment component 5, clamping frames 6, tightening component 8 and tightening blocks 9, the first servo motor 51 drives the bidirectional lead screw 52 to rotate, which drives the two sets of clamping frames 6 to move towards the center position at the same time. This makes the clamping plate 10 clamp and position the two ends of the bucket shafts of different lengths. The second servo motor 81 drives the tightening plate 82 to rotate, which makes the four sets of tightening blocks 9 move towards the center position of the bucket shaft. The bucket shafts of different diameters are clamped simultaneously from the longitudinal and lateral directions. The bucket shafts of different specifications are clamped and positioned at multiple points from the transverse, longitudinal and lateral directions. This improves the firmness and stability of the bucket shaft positioning and avoids displacement that may affect processing.

[0019] Specifically, the adjustment component 5 includes a first servo motor 51 fixedly installed at one end of the positioning rail 4, and a bidirectional lead screw 52 is fixedly installed at the output end of the first servo motor 51.

[0020] In this embodiment, the first servo motor 51 drives the bidirectional lead screw 52 to rotate, which in turn drives the two sets of clamping frames 6 to move towards the center position at the same time, so that the clamping plate 10 clamps and positions the two ends of the bucket shafts of different lengths.

[0021] Specifically, the tightening component 8 includes a second servo motor 81 fixedly mounted on one side of the positioning disk 7, and a tightening disk 82 is fixedly mounted on the output end of the second servo motor 81.

[0022] In this embodiment, the second servo motor 81 drives the tightening disc 82 to rotate, causing the four sets of tightening blocks 9 to move toward the center of the bucket shaft, clamping bucket shafts of different diameters simultaneously from the longitudinal direction and the side.

[0023] Specifically, a rotating groove is provided in the middle of the tightening disc 82, and a clamping disc 10 is rotatably arranged inside the rotating groove.

[0024] In this embodiment, the rotating groove facilitates the sliding of the clamping disc 10.

[0025] Specifically, the clamping frame 6 has fixed tubes on all four sides of its inner wall, and telescopic tubes are slidably installed inside the fixed tubes. One end of the telescopic tube is fixedly connected to the tightening block 9.

[0026] In this embodiment, the fixed tube and the telescopic tube are used to limit the tightening block 9.

[0027] Specifically, a fixed pad 11 is fixedly installed on one side of the top surface of the processing table 1, and the bottom of the conversion frame 3 is rotatably connected to the fixed pad 11.

[0028] In this embodiment, the fixed pad 11 facilitates the rotation of the conversion frame 3.

[0029] Specifically, a limiting groove is provided inside the positioning track 4, and both sets of clamping frames 6 are slidably set inside the limiting groove.

[0030] In this embodiment, the limiting groove facilitates the sliding of the clamping frame 6.

[0031] The working principle and usage process of this utility model: When positioning the bucket shaft, the first servo motor 51 drives the bidirectional lead screw 52 to rotate, which drives the two sets of clamping frames 6 to move towards the center position on the positioning track 4 at the same time, so that the clamping plate 10 clamps and positions the two ends of the bucket shafts of different lengths. The second servo motor 81 drives the tightening plate 82 to rotate. Since the rotating groove on the surface of the tightening plate 82 is arc-shaped and the distance to the tightening plate 82 gradually gets closer, the tightening plate 82 will drive the four sets of tightening blocks 9 to move towards the center position of the bucket shaft when it rotates. At the same time, the telescopic tube will slide inside the fixed tube to limit the tightening blocks 9. The bucket shafts of different diameters are clamped from the longitudinal and lateral directions at the same time. The bucket shafts of different specifications are clamped and positioned at multiple points from the transverse, longitudinal and lateral directions, which improves the firmness and stability of the bucket shaft positioning and avoids displacement that affects the processing. When a set of bucket shafts is installed on one of the positioning rails 4 for processing, a new bucket shaft is installed on another positioning rail 4. After the previous set of bucket shafts is processed, the conversion servo motor 2 drives the conversion frame 3 to rotate, so that the positions of the bucket shafts on the three sets of positioning rails 4 are exchanged. The operator can remove the processed bucket shaft and install the new bucket shaft. At the same time, another set of bucket shafts is being processed. The processing and loading / unloading stations do not interfere with each other, reducing the waiting time for loading and unloading workpieces and improving processing efficiency.
