Description

Technical Field

[0001] The utility model relates to the field of mechanical engineering, in particular to an electric broken wire extractor. Background Art

[0002] Traditional broken wire extractors are usually manually operated tools. Manual broken wire extractors require users to exert greater force and precise operations to remove broken bolts, which is not only laborious to operate, but also easy to cause fatigue for long-term work. Traditional tools are usually not designed with a special mechanism to fix the sleeve, which may cause the sleeve to slip or become unstable during use, affecting the operation effect and safety. Broken wire extractors without impact function may require greater force to turn or pull out the bolt, which increases the risk of additional damage to surrounding materials (such as threaded holes). Existing broken wire extractors (publication number: CN208896022U) have the following disadvantages when used:

[0003] 1. Traditional broken wire extractors are usually manually operated tools. Manual broken wire extractors require users to exert greater force and precise operation to remove broken bolts. This is not only laborious in operation, but also easy to cause fatigue for long-term work. Therefore, electric broken wire extractors are urgently needed;

[0004] 2. Traditional tools usually do not have a special mechanism for fixing the sleeve, which may cause the sleeve to slip or become unstable during use, affecting the operation effect and safety. Therefore, a broken wire extractor with a reliable sleeve fixation is urgently needed;

[0005] 3. A broken wire extractor without an impact function may require greater force to turn or pull out the bolt, which increases the risk of additional damage to surrounding materials (such as threaded holes), so an electric broken wire extractor with an impact function is urgently needed. Utility Model Content

[0006] The main purpose of the utility model is to provide an electric broken wire extractor, which can effectively solve the problems in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] An electric broken wire extractor comprises an extractor housing, a control button is installed on the outer side of the extractor housing, a battery is installed at the inner end of the extractor housing, the battery is connected to a motor, the motor is installed with a motor shaft, the end of the motor shaft is connected to a sleeve head, a hexagonal retaining ring is installed inside the sleeve head, a magnet is arranged at the bottom of the sleeve head, a fixing plate is arranged in front of the motor, and the motor shaft passes through the fixing plate. Four hexagonal retaining ring arrays are arranged. A movable vibration block is installed on the motor shaft. A fixed vibration block is installed on the fixing plate. A universal joint is installed on the motor shaft. The motor shaft is connected to the sleeve head through a universal joint.

[0009] Preferably, four hexagonal retaining spring arrays are provided.

[0010] Preferably, the motor shaft is mounted with a movable vibration block.

[0011] Preferably, a fixed vibration block is installed on the fixed plate.

[0012] Preferably, the motor shaft is mounted with a universal joint.

[0013] Preferably, the motor shaft is connected to the sleeve head via a universal joint.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. By using a motor and a universal joint, the motor provides stable and powerful power output, making it easy and quick to remove broken bolts. This not only reduces the labor intensity of the operator, but also significantly improves work efficiency. The use of a universal joint allows the sleeve to rotate freely at different angles, which enables the tool to operate flexibly in complex or narrow spaces. The torque transmission of the universal joint can effectively convert the power of the motor into the required rotation and impact force, and can maintain torque stability and efficiency even in an environment with restricted angles. The size and direction of the torque can be precisely adjusted through the motor control system to ensure that the bearing range of the bolt or screw is not exceeded during tightening or disassembly;

[0016] 2. Hexagonal circlip and magnet method. The circlip is fixed in the socket head, which can firmly grasp the screw or bolt head to ensure that the socket will not slip off during rotation or impact, thus providing more stable and reliable operation. The use of magnets increases the adsorption force between the socket and the bolt head, further ensuring that the bolt will not fall off during operation, especially when extracting smaller or worn bolts;

[0017] 3. By using the impact block, the fixed vibration block and the movable vibration block are designed to generate impact force under the drive of the motor. When the motor rotates the transmission shaft, the movable vibration block is slightly displaced and impacted under the constraint of the fixed vibration block. This design simulates the working principle of pneumatic or electric impact drills. This impact can effectively break the bond between the bolt and the thread caused by rust, over-tightening or long-term immobilization. At the same time, the dispersion of the impact force reduces the potential damage to the threaded hole or surrounding materials, protecting the integrity of the working surface.

[0027] Example

[0028] See also Figure 1-5 , the utility model provides a technical solution:

[0029] An electric broken wire extractor comprises an extractor housing 1, a control button 2 is installed on the outer side of the extractor housing 1, a battery 12 is installed at the inner end of the extractor housing 1, the battery 12 is connected to a motor 5, the motor 5 is installed with a motor shaft 6, the end of the motor shaft 6 is connected to a sleeve head 3, a hexagonal retaining ring 4 is installed inside the sleeve head 3, a magnet 11 is arranged at the bottom of the sleeve head 3, a fixing plate 9 is arranged in front of the motor 5, and the motor shaft 6 passes through the fixing plate 9. Four hexagonal retaining rings 4 are arranged in an array. A movable vibration block 7 is installed on the motor shaft 6. A fixed vibration block 8 is installed on the fixing plate 9. A universal joint 10 is installed on the motor shaft 6. The motor shaft 6 is connected to the sleeve head 3 through the universal joint 10.

[0030] The specific working process of the utility model is as follows:

[0031] The user turns on the extractor by pressing the control button, and then the battery powers the motor, which starts running and transmits power through the motor shaft. The end of the motor shaft is connected to the socket head through a universal joint, so that the socket head can move freely in multiple directions, increasing the flexibility of operation. Four hexagonal retaining springs are installed inside the socket head to fix and drive the bolts. At the same time, the magnet at the bottom of the socket head enhances the adsorption force with the bolts to ensure that the bolts do not fall off during operation. The movable vibration block and the fixed vibration block work together to generate impact force to help break the bond between the bolt and the thread caused by rust or over-tightening. After the operation is completed, the user can stop the equipment by pressing the control button, or the equipment can be designed to stop automatically after the bolt is removed. This design significantly reduces the labor intensity of the operator, improves work efficiency and safety, and reduces potential damage to surrounding materials.

[0032] By using a motor and a universal joint, the motor provides stable and powerful power output, making it easy and quick to remove broken bolts. It effectively reduces the labor intensity of the operator and improves work efficiency by 65%. The use of a universal joint allows the sleeve to rotate freely at different angles, which enables the tool to operate flexibly in complex or narrow spaces. The torque transmission of the universal joint can effectively convert the power of the motor into the required rotation and impact force, and maintain the stability and efficiency of the torque even in an environment with restricted angles. The size and direction of the torque can be accurately adjusted through the motor control system to ensure that the bearing range of the bolt or screw will not be exceeded during tightening or disassembly, reducing the probability of bolt or screw breakage by 50%.
