Description

Technical Field

[0001] This utility model relates to the field of torque control installation equipment, and in particular to a fastener torque control installation equipment. Background Technology

[0002] Torque control installation equipment is mainly used in industrial production processes to precisely control the torque of components during installation, fastening, or disassembly. This type of equipment can ensure operation according to the set torque value, avoiding damage to parts, loose connections, or other quality problems caused by excessive or insufficient torque. This torque control installation equipment is mainly used for installing fasteners and is quite common in the existing technology.

[0003] Existing technologies, such as the utility model patent with publication number CN205977951U, disclose a temporary fastener for aircraft assembly. This patent uses a precision hexagonal socket screw, a temporary fastener body, a protective sleeve, a retaining ring, and clamping claws. The precision hexagonal socket screw is driven clockwise by a handheld tool or an automated equipment drive unit, causing the clamping claws to move axially. The clamping claws, with their tapered barbed four-lobed or six-lobed structure, open and contact the aircraft structural components during axial movement, simultaneously applying a set torque value for pre-tightening, thus achieving the purpose of connecting two aircraft structural components with the temporary fastener. The clamping force of the temporary fastener is precisely controlled by the equipment control system through closed-loop feedback from a torque sensor. This temporary fastener facilitates automated installation, significantly improving the assembly quality and efficiency of aircraft.

[0004] In the existing technology, when operators use electric wrenches to install fasteners, they usually hold the wrench handle directly. If the fastener requires a large tightening torque, the resulting reaction force will be transmitted to the operator's hand through the tool. Since the electric wrench lacks an effective hand restraint device, this reaction torque can easily cause the tool to slip out of the hand, which not only affects the stability of the operation but also poses certain safety hazards.

[0023] Please see Figure 1 The present invention provides a fastener torque control installation device, comprising: an electric wrench 1, wherein the electric wrench 1 is internally equipped with a battery 2, a torque adjustment device 5, a start switch 4 and a fixing clamp 6, and a limiting structure 3 is provided on one side of the electric wrench 1.

[0024] In the embodiments of this utility model, please refer to Figures 2 to 4The limiting structure 3 includes a fixed frame 301 and a fixed plate 306. The fixed frame 301 is fixedly connected to the electric wrench 1, and the fixed plate 306 is fixedly connected to the electric wrench 1. A rotating rod 302 is rotatably connected to the inner wall of the fixed frame 301. A limiting band 303 is fixedly connected to the arc surface of the rotating rod 302. An insert plate 304 is fixedly connected to the end of the limiting band 303 away from the rotating rod 302. A toothed plate 305 is fixedly connected to the inner wall of the insert plate 304. Two side plates 307 and two limiting blocks 311 are fixedly connected to the upper surface of the fixed plate 306. The inner wall of the limiting block 311 is provided with a positioning groove 312, and the inner wall of the side plate 307 is provided with two limiting... The inner wall of the groove 308 is slidably connected to an adjusting block 322. The inner wall of the groove 308 is fixedly connected to a limiting rod 309. The limiting rod 309 is slidably connected to the adjusting block 322. A spring 310 is sleeved on the arc surface of the limiting rod 309. The two ends of the spring 310 are fixedly connected to the limiting groove 308 and the adjusting block 322 respectively. The four adjusting blocks 322 are in pairs. A moving plate 314 is fixedly connected to the side of the two sets of adjusting blocks 322 that are close to each other. A rack 313 is fixedly connected to the inner wall of the moving plate 314. The rack 313 meshes with the rack 313. The two positioning grooves 312 are slidably connected to the insert plate 304. When personnel need to install fasteners using a wrench, they can move the insert plate 304 to limit the position of the limit band 303 on their hands, thereby improving the stability of the wrench grip and reducing hand fatigue. A fixing block 316 is fixedly connected to one side of the side plate 307. An auxiliary rod 317 is rotatably connected to the inner wall of the two fixing blocks 316. A gear 318 is fixedly connected to the arc surface of the auxiliary rod 317, meshing with a toothed plate 305. A rotating block 319 is fixedly connected to one end of the auxiliary rod 317. This allows personnel to easily adjust the tightness of the limit band 303, improving operational convenience. A pull ring 315 with a circular cross-section is fixedly connected to the upper surface of the moving plate 314. The pull ring 315 facilitates the movement of the movable plate 314, improving operational convenience. A bellows 323 is fitted over the arc-shaped surface of the spring 310, with both ends of the bellows 323 fixedly connected to the limiting groove 308 and the adjusting block 322, respectively. The bellows 323 protects the spring 310, preventing direct contact with other substances and extending its service life. Several anti-slip grooves 320 are evenly distributed on the arc-shaped surface of the rotating block 319, increasing friction between the user's hand and the rotating block 319 and preventing slippage during rotation. A guide strip 321 is fixedly connected to the side of the insert plate 304 away from the limiting band 303. The guide bar 321 can limit the insertion plate 304, making it easier for personnel to slide the insertion plate 304 into the inner wall of the two positioning grooves 312; The working principle of the fastener torque control installation device provided by this utility model is as follows: When a person needs to install a fastener, the person first adjusts the torque adjustment device 5 on the electric wrench 1 according to the torque required for the fastener. Then, the person installs the sleeve adapted to the fastener inside the electric wrench 1 through the fixing clamp 6. The person then installs the fastener by turning on the switch 4. When the fastener reaches a certain torque, the electric wrench will make a sound, preventing the sleeve from rotating. When a person needs to use the electric wrench 1 to install a fastener with a higher torque, the person can first move the insert plate 304. The insert plate 304 drives the guide strip 321 and the limiting band 303 to move closer to the limiting block 311. 304 also drives the toothed plate 305 to move closer to the limiting block 311. At this time, the limiting band 303 will also drive the rotating rod 302 to rotate until the guide strip 321 and the insert plate 304 slide into the inner wall of the two positioning grooves 312. Then, during the sliding process of the insert plate 304 in the two positioning grooves 312, the toothed plate 305 will abut against the rack 313. Then, the toothed plate 305 drives the rack 313 to move upward. The rack 313 drives the moving plate 314 to move upward. The moving plate 314 drives the pull ring 315 and the four adjusting blocks 322 to move upward. The pull ring 315 can facilitate the movement of the moving plate 314 by personnel, which can improve the convenience of operation. Then, the adjusting blocks 322 move on the arc surface of the limiting rod 309. As the sliding motion continues, the adjusting block 322 also drives the spring 310 and the bellows 323 to rewind. The bellows 323 protects the spring 310, preventing direct contact with other substances and extending its service life. This continues until the rack 313 and the toothed plate 305 are misaligned. At this point, the four springs 310 rebound, causing the rack 313 to move closer to the toothed plate 305. The toothed plate 305 then moves to the appropriate position, meshing with the gear 318 and rotating it. The gear 318 then rotates the auxiliary rod 317, which in turn rotates the rotating block 319 until a suitable distance is maintained between the limit band 303 and the electric wrench. Then, the operator passes their hand between the limiting band 303 and the electric wrench. If the operator finds that the limiting band 303 is too long to effectively fit the back of their hand, they can rotate the rotating block 319. The anti-slip groove 320 on the inner wall of the rotating block 319 increases the friction between the operator's hand and the rotating block 319, preventing slippage during rotation. The rotating block 319 then drives the auxiliary rod 317 to rotate, which in turn drives the gear ring to rotate. The gear ring moves the gear plate 305 away from the fixed frame 301. The gear plate 305 moves the rack 313 upward, and also moves the insert plate 304 and guide strip 321 away from the fixed frame 301.The guide strip 321 can limit the insertion plate 304, allowing personnel to easily slide the insertion plate 304 into the inner walls of the two positioning slots 312. Then, the insertion plate 304 drives one end of the limiting band 303 to move away from the fixed frame 301 until the limiting band 303 is in contact with the back of the personnel's hand. The rotating block 319, auxiliary rod 317, and gear 318 allow personnel to easily adjust the tightness of the limiting band 303, thereby improving the ease of operation.
