TECHNICAL FIELD

[0001] The utility model belongs to nut fastening machinery field, especially relates to a kind of electric nut tightening equipment. BACKGROUND

[0002] Nuts are widely used as fasteners in mechanical and construction fields, and their main function is to connect and fix through cooperation with bolts or screws. However, in actual application, traditional manual tightening tools often need a large space to apply force, and the operation efficiency is low, which can easily cause worker fatigue and affect work quality. In addition, with the increasing complexity of equipment, many connecting parts are designed in narrow spaces, and traditional manual tools are difficult to operate effectively.

[0003] To improve production efficiency and product quality, various types of nut tightening equipment have appeared in the market. For example, intelligent electric nut tightening machines integrate computers, electromechanical and intelligent tightening management functions, which can effectively replace traditional manual and pneumatic tightening methods to ensure higher tightening precision and assembly efficiency. In addition, some devices also use servo motors and closed-loop control systems to detect nut tightening torque in real time, further ensuring the quality stability of products. However, most products do not fully consider the use requirements of narrow spaces in design. These tools are often large in size and heavy in weight, making it difficult to operate flexibly in narrow working environments and unable to meet the tightening requirements of specific angles and positions. This not only reduces work efficiency, but also may cause uneven nut tightening or damage to parts. SUMMARY

[0004] The utility model intends to provide a kind of electric nut tightening equipment, to solve the problem that the nut tightening tool of existing in narrow space is difficult to tighten operation, cannot meet the tightening requirements of specific angle and position.

The first shell and the second shell are hollow inside. The side wall of the second shell is provided with a plurality of motor fixing ears for fixing the motor. The inside of the first shell and the second shell is provided with a tightening sleeve, which is hollow inside. The upper end of the tightening sleeve is rotatably connected with the first shell and the second shell. The bottom of the tightening sleeve is provided with a gear tooth. The side wall of the second shell is provided with a through slot, which can expose part of the gear teeth of the side wall of the tightening sleeve. The inside of the tightening sleeve near the gear-shaped end is detachably connected with a sleeve. The center of the sleeve is provided with a nut-shaped through slot.

[0006] The working principle of the present scheme is: in daily work, some nuts need to be screwed or anchored in a small space, at this time the shell one, the shell two and the tightening sleeve can be installed together, and the shell one and the shell two are fixed by using the screw, at this time the tightening sleeve can rotate inside the shell one and the shell two, and the side part containing the gear teeth is exposed outside the shell two, then the sleeve with the same size as the required tightening nut is selected, the sleeve is installed inside the side of the tightening sleeve containing the gear teeth, the motor fixing lug of the side wall of the shell two is fixed to the side wall of the motor, the rotating end of the motor is fixedly connected with the gear meshing with the gear teeth of the tightening sleeve, after the sleeve is placed on the nut to be tightened, the motor can be started to drive the gear to rotate, thereby driving the tightening sleeve inside to rotate, the tightening sleeve drives the sleeve inside to rotate, and the nut is tightened.

[0007] Beneficial effects: 1. The equipment places the motor for tightening the nut on the side wall of the whole equipment, drives the gear by the motor, and drives the tightening sleeve to rotate, which can greatly reduce the space occupied during installation and reduce the required longitudinal distance during installation, facilitating use in a small space.

[0008] 2. The equipment can replace the matching sleeve according to the size of the nut to be tightened, and is suitable for use in more situations.

[0009] 3. The inside of the shell one, the shell two, the tightening sleeve and the sleeve is hollow, and the hollow equipment can match more use environments, such as tightening of the nut in fasteners such as screws, bolts and anchors, avoiding insufficient space when tightening the nut, which limits the tightening distance of the nut.

[0010] Further, the side wall of the tightening sleeve is fixedly connected with an annular rotating block near the upper position, the shell one and the shell two are provided with grooves similar to the rotating block near the upper position, the rotating block is rotationally connected in the groove, and bearings are rotationally connected to the upper and lower sides of the rotating block, one side of the bearing is in contact with the rotating block of the tightening sleeve, and the other side is in contact with the groove of the shell one and the shell two. The bearing can assist the rotation of the tightening sleeve, reduce the friction force during the rotation of the tightening sleeve, and facilitate more accurate control of the torque of the tightened nut.

[0011] Further, the grooves of the shell one and the shell two are provided with first bearing grooves at the bottom, and the top end of the tightening sleeve is provided with second bearing grooves, and the two bearings are rotationally connected in the first bearing grooves and the second bearing grooves. The bearing grooves limit the movement space of the bearing, avoid the bearing from deviating from the position during rotation, and affect the tightening of the nut.

[0012] Further, the outer side wall of the junction of the shell one and the shell two is fixedly connected with a plurality of fixing ears, and the fixing ears of the shell one and the shell two are matched with each other. During installation, fasteners such as bolts can be used to fix the two together, avoiding separation and falling off during rotation.

[0013] Further, the inside of the tightening sleeve is provided with a plurality of mounting grooves near one side of the gear teeth, and the outer side wall of the sleeve is fixedly connected with a plurality of mounting blocks, and the mounting grooves and the mounting blocks are matched with each other. The mounting block and the mounting groove facilitate the installation of the sleeve and the subsequent tightening of the nut to avoid the rotation of the sleeve.

[0014] Further, the tightening sleeve and the sleeve can be longitudinally divided into two parts. The tightening sleeve and the sleeve which can be divided into two parts are more convenient for installation and disassembly of the equipment, and are suitable for smaller space. During use, they are assembled in the shell one and the shell two, and then the complete whole is assembled for use. BRIEF DESCRIPTION OF DRAWINGS
