Description

Technical Field

[0001] This utility model relates to the field of auger welding technology, and in particular to an auger that is easy to weld. Background Technology

[0002] In modern industry and engineering, an auger typically refers to a mixing device widely used for mixing, stirring, and transporting various liquids or slurries. It usually consists of an auger shaft and spiral auger blades. An auger can effectively mix liquids or solids of different compositions evenly. During the production of an auger, the auger shaft and spiral auger blades need to be welded together. However, most existing augers still have problems that need to be solved when welding them together.

[0003] Most existing augers lack a mechanism to restrain the auger shaft and the spiral auger blades. During welding, the auger shaft and spiral auger blades may shift due to external forces. This shift can lead to incomplete contact at the welded joint, resulting in weld defects such as incomplete penetration and porosity. This reduces weld strength and stability, lowers structural strength, and causes operational instability. Furthermore, welding requires additional manpower to stabilize the auger shaft and spiral auger blades, making the operation cumbersome. Therefore, a welding-friendly auger is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a auger that is easy to weld.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An auger for easy welding includes an auger shaft, auger blades fitted on the outer wall of the auger shaft, an arc-shaped fixing plate fixedly connected to one side of each auger blade, a fixing shaft fixedly connected to one side of the auger shaft, four shaft grooves on the fixing shaft, a fixing ring fitted on the fixing shaft, four locking blocks fixedly connected to the inner wall of the fixing ring, the locking blocks fitting into the shaft grooves, the locking blocks being disposed within the shaft grooves, three positioning grooves on one side of each auger blade, each positioning groove containing a positioning pin, the positioning pin fitting into the positioning groove, and each positioning pin being fixedly connected to the side of the fixing ring near the auger blade, the fixing shaft having a circular groove containing a cylinder, the cylinder being fixedly connected to the fixing shaft, and a pin inside the cylinder passing through the locking blocks and the fixing ring. Because of the use of positioning pins and an arc-shaped fixing plate for positioning the auger blades, when the positioning pin is in the positioning groove, the arc-shaped fixing plate cannot be positioned within the auger blade. Rotation on the shaft restricts the auger blades, preventing them from rotating on the auger shaft and avoiding positional misalignment between the auger shaft and blades during welding. Inserting the pin into the cylinder ensures the stability of the fixing ring and keeps the positioning pin stably within the positioning groove. This effectively solves the problem mentioned in the background art: most existing augers lack a mechanism to restrict the movement between the auger shaft and the spiral auger blades. During welding, the auger shaft and blades may shift due to external forces, requiring additional manpower to stabilize them, which is cumbersome. This method ensures that the position of the auger blades and shaft does not shift during welding, guaranteeing a perfect fit of the weld surface, reducing the risk of welding defects, improving weld strength and overall stability, and eliminating the need for additional manpower to fix the auger shaft and blades, thus facilitating welding.

[0006] As a further embodiment of this utility model, a handle is fixedly connected to the top of the pin, and several anti-slip grooves are provided on the outer side wall of the handle.

[0007] As a further embodiment of this utility model, each of the fixing rings is provided with a square groove, and a first magnet and a second magnet are provided in the square groove. The second magnet is fixedly connected to the outer wall of the pin, and the first magnet is fixedly connected to the fixing ring. The first magnet, the locking block and the fixing ring are all provided with grooves that are compatible with the pin.

[0008] As a further embodiment of this utility model, a retaining ring is fixedly connected to the auger shaft on the side away from the fixed shaft.

[0009] As a further embodiment of this utility model, the retaining ring and the outer wall of the auger shaft are fixedly connected to two mounting plates.

[0010] As a further embodiment of this utility model, the mounting plate is provided with a plurality of mounting holes.

[0011] The beneficial effects of this utility model are as follows: By employing a positioning pin and an arc-shaped fixing plate to position the auger blades, the arc-shaped fixing plate cannot rotate on the auger shaft when the positioning pin is in the positioning groove. This restricts the auger blades from rotating on the auger shaft, preventing positional misalignment between the auger shaft and the auger blades during welding. Inserting the pin into the cylinder ensures the stability of the fixing ring, allowing the positioning pin to remain stably within the positioning groove. This effectively solves the problem mentioned in the background section where most existing augers lack a proper positioning mechanism for the auger shaft and auger blades. The mechanism that restricts the position of the auger shaft and the spiral auger blades may shift due to external forces during welding. This requires additional manpower to stabilize the auger shaft and spiral auger blades during welding, which is quite troublesome. This technology ensures that the position of the auger blades and auger shaft does not shift during welding, thereby ensuring that the contact surface of the weld is completely matched, reducing the risk of welding defects, improving welding strength and overall stability, and eliminating the need for additional manpower to fix the auger shaft and auger blades, thus facilitating welding.

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-7 A welding-friendly auger includes an auger shaft 1, with auger blades 2 sleeved on the outer wall of the auger shaft 1. An arc-shaped fixing plate 201 is fixedly connected to one side of the auger blades 2. A fixing shaft 3 is fixedly connected to one side of the auger shaft 1. Four shaft grooves 4 are formed on the fixing shaft 3. A fixing ring 5 is sleeved on the fixing shaft 3. Four locking blocks 6 are fixedly connected to the inner wall of the fixing ring 5. The locking blocks 6 are adapted to the shaft grooves 4 and are disposed within the shaft grooves 4. Three positioning grooves 202 are formed on one side of the auger blades 2. Each of the three positioning pins 7 is equipped with a positioning pin 7, which is adapted to the positioning groove 202. All three positioning pins 7 are fixedly connected to the fixing ring 5 on the side near the auger blade 2. A circular groove 301 is opened on the fixing shaft 3, and a cylinder 8 is installed inside the circular groove 301. The cylinder 8 is fixedly connected to the fixing shaft 3, and a pin 9 is installed inside the cylinder 8. The pin 9 passes through the locking block 6 and the fixing ring 5. Due to the use of positioning pins and an arc-shaped fixing plate to position the auger blade, when the positioning pin is in the positioning groove, the arc-shaped fixing plate... The fixed plate cannot rotate on the auger shaft, thus restricting the auger blades and preventing them from rotating on the shaft. This avoids positional misalignment between the auger shaft and blades during welding. Inserting the pin into the cylinder ensures the stability of the fixing ring and keeps the positioning pin stably within the positioning groove. This effectively solves the problem mentioned in the background art: most existing augers lack a mechanism to restrict the auger shaft and blades. During welding, the auger shaft and blades may shift due to external forces, requiring additional manpower to stabilize them, which is cumbersome. This invention ensures that the position of the auger blades and shaft does not shift during welding, guaranteeing a perfect fit of the weld surface, reducing the risk of welding defects, improving weld strength and overall stability, and eliminating the need for additional manpower to fix the auger shaft and blades, thus facilitating welding.

[0016] In this embodiment, a handle 10 is fixedly connected to the top of the pin 9. Several anti-slip grooves are provided on the outer side wall of the handle 10. The handle 10 can be pulled to remove the pin 9 and release the restriction, so that the fixing ring 5 can be removed from the fixing shaft 3.

[0017] In this embodiment, a square groove 11 is provided on each of the fixing rings 5. A first magnet 12 and a second magnet 13 are provided in the square groove 11. The second magnet 13 is fixedly connected to the outer wall of the pin 9, and the first magnet 12 is fixedly connected to the fixing ring 5. The first magnet 12, the locking block 6 and the fixing ring 5 are all provided with grooves that are compatible with the pin 9. The first magnet 12 and the second magnet 13 are attracted by opposite poles, so that the pin 9 can be stably placed inside the cylinder 8.

[0018] In this embodiment, a retaining ring 15 is fixedly connected to the auger shaft 1 on the side away from the fixed shaft 3.

[0019] In this embodiment, the retaining ring 15 and the outer wall of the auger shaft 1 are fixedly connected to two mounting plates 14.

[0020] In this embodiment, the mounting plate 14 is provided with a plurality of mounting holes 16, and bolts can be used to pass through the mounting holes 16 to fix the mounting plate 14 to the drive fixture, so as to ensure the stability of the auger shaft 1 and the auger blade 2 when rotating.

[0021] Working principle: During welding, the auger blade 2 is fitted onto the auger shaft 1, with the arc-shaped fixing plate 201 tightly against the auger shaft 1. Then, the fixing ring 5 is fitted onto the fixing shaft 3, with the locking block 6 positioned within the fixing shaft 3. At this point, the fixing ring 5 can only slide on the fixing shaft 3 and will not rotate. The positioning pin 7 is inserted into the positioning groove 202, which restricts the arc-shaped fixing plate 201, preventing it from rotating. This causes the auger blade 2 to rest against the mounting plate 14 on the side away from the arc-shaped fixing plate 201, further restricting the auger blade 2 and preventing it from rotating or moving on the auger shaft 1. Finally, the pin 9 is passed through the fixing ring 5 and the locking block 6 and inserted into the cylinder 8, further restricting the fixing ring 5. The fixing ring 5 is prevented from moving on the fixing shaft 3, thus ensuring that the positioning pin 7 is stably positioned in the positioning groove 202. The second magnet 13 is attracted to the first magnet 12, thus ensuring that the pin 9 is stably positioned in the cylinder 8. At this point, welding can be carried out. Since the auger blade 2 cannot move or rotate on the auger shaft 1, the positions of the auger shaft 1 and the auger blade 2 are stable during the welding process. The positions of the auger shaft 1 and the auger blade 2 will not be offset due to external forces, ensuring smooth welding, reducing the difficulty of operation, and facilitating welding. After the welding is completed, pull the handle 10 to remove the pin 9 from the cylinder 8, thus releasing the restriction on the fixing ring 5. The fixing ring 5 can then be removed from the fixing shaft 3.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
