Description

Technical Field

[0001] This utility model relates to the field of electric wrench technology, specifically an electric wrench that facilitates horizontal limiting. Background Technology

[0002] Electric wrenches, as efficient power tools, are specifically designed for tightening and loosening bolts and nuts, exhibiting significant advantages, especially when handling high-strength bolts. With their powerful output, these tools can quickly and accurately tighten or loosen nuts in different locations, effectively promoting stable connections and convenient disassembly between components, thereby greatly improving the overall structural stability and assembly efficiency of the device.

[0003] However, current electric wrenches have several drawbacks. Their weight and the reaction force from the nut as the socket rotates contribute to poor stability, leading to uneven horizontal stability during tightening and potentially stripping the screw. Furthermore, current electric wrenches offer two power supply options: socket power and battery power. These two power supply systems are not interchangeable, resulting in either limited portability with socket power or insufficient battery life with battery power, thus limiting their practicality.

[0004] Therefore, an electric wrench that facilitates horizontal limiting is needed to improve the above-mentioned problems. Utility Model Content

[0005] To address the issues of heavy electric wrenches with easy horizontal limiting and the reaction force exerted by the nut on the rotating socket, which reduces wrench stability and leads to poor horizontal stability during tightening and stripping of screws, this invention provides an electric wrench with easy horizontal limiting to solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electric wrench for easy horizontal limiting includes a wrench body, a controller embedded in the outer wall of the wrench body, a horizontal limiting component installed at one end of the wrench body, a power supply connection component installed at the other end of the wrench body, a torque adjustment knob provided on the outer wall of the wrench body, and an on / off switch provided on the outer wall of the wrench body.

[0008] As a preferred embodiment of this utility model, the horizontal limiting component includes a mounting base, a universal joint, and a TOF distance sensor. The mounting base is mounted on the outer wall of the trigger body. The mounting base has a ring structure. The outer wall of the mounting base has multiple mounting grooves located on the outer wall of the mounting base. A fixing block is installed on the inner wall of the mounting groove.

[0009] As a preferred embodiment of this utility model, a rotating shaft is rotatably connected to the inner wall of the fixed block, and an electrically controlled limiting cylinder is rotatably connected to the outer wall of the rotating shaft. One end of the electrically controlled limiting cylinder is rotatably connected to the rotating shaft, and a limiting block is installed at one end of the rotating shaft. A collar base is installed on the inner wall of the limiting block, wherein multiple sets of limiting blocks are provided and are respectively located on the outer wall of the collar base.

[0010] As a preferred embodiment of this utility model, the universal joint is installed at the output end of the wrench body, and a fixed base is installed at one end of the universal joint, with a wrench sleeve installed on the outer wall of the fixed base.

[0011] As a preferred embodiment of this utility model, a collar base is rotatably connected to the outer wall of the fixed base, and multiple sets of ToF distance sensors are provided and located on the outer wall of the trigger body, with the ToF distance sensors located on one side of the mounting base.

[0012] As a preferred embodiment of this utility model, the power supply connection assembly includes a power supply base, which is installed on the bottom outer wall of the trigger body. A limiting slot is formed on the opposite outer wall of the power supply base. A power supply interface is symmetrically formed on one side of the limiting slot and on the outer wall of the power supply base. An energy storage device is inserted and removed from the inner wall of the limiting slot.

[0013] As a preferred embodiment of this utility model, a connection interface is installed on the inner wall of the energy storage device, wherein the connection interface and the power supply interface are connected by a plug-in connection, and a power supply line is installed on the bottom outer wall of the power supply base, with a power supply plug-in interface installed at one end of the power supply line.

[0014] As a preferred embodiment of this utility model, the controller is connected to a trigger body, a torque adjustment knob, an on / off switch, a TOF distance sensor, an electronically controlled limit cylinder, and a power supply interface via wires, and the connection method is an electrical connection.

[0015] Compared with the prior art, this utility model, by setting a horizontal limiting component in the electric wrench that facilitates horizontal limiting, enables the wrench to adjust the position of the wrench sleeve in real time based on sensor data. When the sleeve is aligned with the screw and the controller is activated, the TOF distance sensor first establishes a reference parameter by measuring the initial distance between the wrench body and the screw mounting surface. After the on / off switch is turned on, the controller drives the body to drive the fixed base and sleeve to perform the tightening action via the universal joint. During the operation, the TOF sensor continuously monitors the lateral distance of the sleeve. When the reaction force of the nut causes the sleeve to tilt and the measured value to deviate from the preset parameter, the controller immediately activates the electric limit cylinder, which pushes the collar base to apply a reverse thrust to the sleeve through the rotating shaft. This solves the problem of poor horizontal stability when the wrench is tightening the entire screw, which leads to the problem of stripping the screw during tightening.

[0016] This invention, by incorporating a power supply connection component into an electric wrench designed for easy horizontal positioning, allows for selective power supply based on different usage scenarios. Power is supplied via a power strip plugged into the power supply interface to ensure the device's continuous operation. When the device needs to be moved or tightened, simply unplug the power supply interface, insert the energy storage device into the positioning slot for fixation, and simultaneously insert one end of the energy storage device's connection interface into the power supply interface for secure power supply. This ensures the device's portability and solves the problems of incompatibility between the two power supply structures of electric wrenches, which result in insufficient portability with socket power supply and insufficient battery life with battery power supply, leading to poor practicality.

[0023] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figure 1-5 The electric wrench shown includes a wrench body 1, a controller 2 embedded in the outer wall of the wrench body 1, a horizontal limiting component 3 installed at one end of the wrench body 1, a power supply connection component 4 installed at the other end of the wrench body 1, a torque adjustment knob 5 provided on the outer wall of the wrench body 1, and an on / off switch 6 provided on the outer wall of the wrench body 1.

[0025] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The horizontal limiting assembly 3 includes a mounting base 301, a universal joint 302, and a TOF distance sensor 303. The mounting base 301 is mounted on the outer wall of the trigger body 1. The mounting base 301 has a ring structure, and multiple mounting grooves 304 are provided on the outer wall of the mounting base 301. A fixing block 305 is installed on the inner wall of the mounting groove 304. A rotating shaft 306 is rotatably connected to the inner wall opposite to the fixing block 305. An electrically controlled limiting cylinder 307 is rotatably connected to the outer wall of the rotating shaft 306. One end of the electrically controlled limiting cylinder 307 is rotatably connected to a rotating shaft 308. A limit block 309 is installed at one end of the rotating shaft 308. A collar base 310 is installed on the inner wall of the limit block 309. Multiple sets of limit blocks 309 are provided and are located on the outer wall of the collar base 310. A universal joint 302 is installed at the output end of the wrench body 1. A fixed base 311 is installed at one end of the universal joint 302. A wrench sleeve 312 is installed on the outer wall of the fixed base 311. The collar base 310 is rotatably connected to the outer wall of the fixed base 311. Multiple sets of TOF distance sensors 303 are provided and are located on the outer wall of the wrench body 1. The TOF distance sensors 303 are located on one side of the mounting base 301.

[0026] Based on the above structural features and connection relationships, the controller 2 controls the TOF distance sensor 303 to operate, so that the TOF distance sensor 303 measures the distance between the wrench body 1 and the screw mounting point and generates a distance reference value. At the same time, the controller 2 uses this value as a reference parameter, and then turns on the on / off switch 6, so that the on / off switch 6 generates a signal to the controller 2, thereby causing the controller 2 to control the wrench body 1 to operate. Then, the output end of the wrench body 1 drives the fixed base 311 through the universal joint 302, thereby causing the fixed base 311 to drive the wrench sleeve 312 to rotate.

[0027] In this embodiment, specific references Figure 1 , Figure 2 and Figure 3 The power supply connection assembly 4 includes a power supply base 401, which is mounted on the bottom outer wall of the trigger body 1. A limit slot 402 is formed on the opposite outer wall of the power supply base 401. A power supply interface 403 is symmetrically formed on one side of the limit slot 402 and on the outer wall of the power supply base 401. An energy storage device 404 is plugged into and installed on the inner wall of the limit slot 402. A connection interface 405 is installed on the inner wall of the energy storage device 404. The connection method between the connection interface 405 and the power supply interface 403 is a plug-in connection. A power supply line 406 is installed on the bottom outer wall of the power supply base 401. A power supply plug-in interface 407 is installed at one end of the power supply line 406.

[0028] The controller 2 is electrically connected to the trigger body 1, torque adjustment knob 5, on / off switch 6, TOF distance sensor 303, electric limit cylinder 307, and power supply interface 403 via wires. This electrical connection powers the device and enables the controller 2 to control the operation of the trigger body 1, torque adjustment knob 5, on / off switch 6, TOF distance sensor 303, electric limit cylinder 307, and power supply interface 403.

[0029] This design facilitates the operation of a horizontally limited electric wrench. During operation, the controller 2 connects the wrench body 1, torque adjustment knob 5, on / off switch 6, TOF distance sensor 303, electric limit cylinder 307, and power supply interface 403 via wires. This electrical connection powers the device, enabling the controller 2 to control the operation of the wrench body 1, torque adjustment knob 5, on / off switch 6, TOF distance sensor 303, electric limit cylinder 307, and power supply interface 403.

[0030] By fitting the wrench sleeve 312 onto the screw being tightened, and pressing the wrench sleeve 312 against the screw, turning on the switch of the controller 2 will cause the controller 2 to control the TOF distance sensor 303 to operate, so that the TOF distance sensor 303 can measure the distance between the wrench body 1 and the screw mounting point and generate a distance reference value. At the same time, the controller 2 uses this value as a reference parameter. Then, the on / off switch 6 is turned on, so that the on / off switch 6 generates a signal to the controller 2, which in turn causes the controller 2 to control the wrench body 1 to operate. Then, the output end of the wrench body 1 drives the fixed base 311 through the universal joint 302, which in turn causes the fixed base 311 to drive the wrench sleeve 312 to tighten.

[0031] The TOF distance sensor 303 measures the distance to one side of the wrench sleeve 312 in real time. At the same time, the TOF distance sensor 303 generates an electrical signal that is transmitted to the controller 2 through a wire. When the wrench sleeve 312 rotates, its nut will generate a reaction force on it. When the wrench sleeve 312 tilts, the data generated by the TOF distance sensor 303 will deviate from the preset parameters. Subsequently, the controller 2 controls the electric limit cylinder 307 to operate, so that one end of the electric limit cylinder 307 pushes the collar base 310 through the rotating shaft 308. This causes the collar base 310 to apply a pushing force to the wrench sleeve 312 through the fixed base 311, so that the wrench sleeve 312 is fixed against it to ensure the stability of the horizontal position of the wrench sleeve 312. This solves the problem of poor horizontal stability when the wrench is tightening the whole, which leads to the problem of stripping the screw when tightening.

[0032] A power supply cable 406 is installed on the bottom outer wall of the power supply base 401. One end of the power supply cable 406 is equipped with a power supply plug-in interface 407. The power supply plug-in interface 407 is inserted into a power strip to provide power and ensure the device's continuous operation. When the device needs to be moved or turned, simply unplug the power supply plug-in interface 407, insert the energy storage device 404 into the limit slot 402 for fixation, and simultaneously insert one end of the connection interface 405 of the energy storage device 404 into the power supply interface 403 for fixation and power supply. This ensures the portability of the device and solves the problem that the two power supply structures of electric wrenches are not interchangeable, which leads to insufficient portability of socket power supply and insufficient battery life of battery power supply, resulting in poor practicality.
