Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for mechanical processing, specifically to an automatic sleeve positioning structure. Background Technology

[0002] In machining and assembly processes, especially in the context of automated welding sleeve machines using digital models, precise sleeve positioning is crucial. Currently, existing sleeve positioning methods primarily employ a positioning screw shaft coupled with a locking nut. In practice, this requires manual insertion of the positioning screw shaft into the sleeve, followed by tightening the locking nut to achieve positioning. This method has several drawbacks: firstly, it is cumbersome, requiring manual installation of the positioning screw shaft and locking nut for each sleeve, consuming significant time and resulting in low production efficiency; secondly, it requires a large number of operators, leading to high labor costs, and manual operation is prone to improper installation, resulting in inaccurate sleeve positioning, affecting subsequent processing or assembly quality, and consequently impacting the overall product quality.

[0022] 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.

[0023] Please see Figure 1-2 An automatic sleeve positioning structure includes a clamping plate 1, a side plate 2, a first bearing 3, a cylinder upper plate 4, a sleeve positioning post 5, a shaft post 6, and a pressure block 7. The side plate 2 is fixedly connected to the corresponding sides of the cylinder upper plate 4 by screws. The clamping plate 1 is fixedly connected to the side plate 2 by screws. The first bearing 3 is placed flat on both sides of the upper and lower planes of the clamping plate 1 and fixedly sleeved on the upper and lower sides of the shaft post 6. The pressure block 7 is fixedly connected to both ends of the shaft post 6 by screws. The sleeve positioning post 5 is fixedly connected to the pressure block 7 by screws. A driving mechanism is provided at the bottom end of the cylinder upper plate 4.

[0024] When using this equipment:

[0025] Equipment installation

[0026] When installing the automatic sleeve positioning structure, first fix the first cylinder 8 in a suitable position to ensure its stability. Then, install the cylinder upper plate 4 on top of the first cylinder 8 with screws, paying attention to the tightening force of the screws to avoid loosening the parts due to excessive looseness or damaging the threads due to excessive tightness. Next, install the two side plates 2 symmetrically on both sides of the cylinder upper plate 4 with screws, ensuring the verticality and stability of the side plates 2. After that, place the first bearings 3 on both sides of the upper and lower planes of the clamping plate 1, and pass the shaft 6 through the first bearings 3. Then connect the pressure block 7 to both ends of the shaft 6 with screws, and finally install the sleeve positioning pin 5 on the pressure block 7 with screws. After installation, check whether the connection of each component is firm and whether the first bearing 3 can rotate flexibly to ensure that the equipment is installed correctly.

[0027] Equipment debugging

[0028] After the equipment is installed, debugging is performed. Connect the first cylinder 8 to the air source, start the air source, and observe whether the piston rod of the first cylinder 8 extends and retracts smoothly and without any jamming. Check whether the sleeve positioning pin 5 can remain vertical during the rising and falling process, and whether the first bearing 3 can rotate normally. During the rising process of the sleeve positioning pin 5, simulate the sleeve positioning operation and observe whether the sleeve positioning pin 5 can accurately extend into the simulated digital model sleeve, and whether its position can be flexibly adjusted in the horizontal direction to achieve the automatic positioning function. If any problems are found, check the installation of each component in time, adjust the tightness of the screws or replace the faulty component until the equipment can operate normally.

[0029] Positioning operation

[0030] In actual use, place the automatic sleeve positioning structure directly below the digital model, ensuring that the sleeve positioning pin 5 is basically aligned with the central axis of the digital model sleeve. Recheck that the air source pressure is between 0.4MPa and 0.6MPa, and that the ambient temperature and humidity are within the specified range. After confirming everything is correct, start the first cylinder 8. The output end of the first cylinder 8 extends upward, pushing the upper cylinder plate 4 and the connected side plate 2, clamping plate 1, shaft column 6, pressure block 7, and sleeve positioning pin 5 upward as a whole. As the sleeve positioning pin 5 gradually approaches the digital model sleeve, the thrust ball bearing, lying flat on both sides of the upper and lower planes of the clamping plate 1 and fitted onto the shaft column 6, causes the thrust ball bearing to rotate on the clamping plate 1 as the shaft column 6 moves. When the sleeve positioning pin 5 contacts the digital model sleeve, the rotation of the thrust ball bearing allows the sleeve positioning pin 5 to flexibly adjust its position in the horizontal direction, achieving automatic alignment with the sleeve's installation position. As the first cylinder 8 continues to push, the sleeve positioning pin 5 gradually extends into the digital model sleeve, completing the sleeve positioning operation.

[0031] Subsequent operation phase

[0032] After the sleeve is positioned, the digital mold automatic sleeve welding machine can perform subsequent welding or other processing operations. After a batch of sleeves is positioned and processed, the output end of the first cylinder 8 retracts, driving the sleeve positioning pin 5 to exit from the digital mold sleeve and return to the initial position, ready for the next round of sleeve positioning operations.

[0033] As a preferred embodiment of the above, the drive mechanism further includes a first cylinder 8, which is located directly below the cylinder upper plate 4, and the output end of the first cylinder 8 is fixedly installed to the corresponding cylinder upper plate 4 by screws.

[0034] As a preferred embodiment of the above, the first bearing 3 is configured as a thrust ball bearing, which is used to enable the sleeve positioning post 5 to slide at any angle in the horizontal direction, and to assist the sleeve positioning post 5 in automatically positioning the digital model sleeve.

[0035] As a preferred embodiment of the above, the clamping plate 1 is made of alloy steel that has been hardened and quenched, resulting in a smooth and wear-resistant surface.

[0036] As a preferred embodiment of the above, the sleeve positioning post 5 is made of USU304 material, which has a smooth and wear-resistant surface.

[0037] As a preferred embodiment of the above, the working environment temperature of the positioning structure is between -5°C and 60°C, the working pressure is between 0.4MPa and 0.6MPa, and the working environment humidity is between 40% and 60%.
