Problems solved by technology

[0003] To replace the filter element, the oil filter nut needs to be removed. During the maintenance process, because the area where the oil filter is located is inside the equipment, its location space is narrow, and the multi-way connection oil pipe is restricted by interference from many obstacles, so disassembly When it comes to oil filter nuts, there is no way to start, and it is very difficult to replace; when disassembling and installing the oil filter element nuts on the equipment, copper rods are used to knock them during maintenance and disassembly, so the locking force cannot be controlled well, and there are also problems when the equipment is working. The phenomenon of fastening nut loosening also increases maintenance time and labor intensity

Embodiment 1

[0027] Such as Figure 1-7 As shown, a wrench for dismounting and assembling an oil filter nut includes an arc-shaped claw 1, a torque rod 2, a locking thread sleeve 3, and a wrench rod 4. One end of the torque rod 2 is connected to the arc-shaped claw 1, and the other end It is connected with the wrench rod, and the middle thread is connected with a locking threaded sleeve 3.

[0028] The working principle of the present invention is: the present invention utilizes the length dimension of the torsion bar 2 to avoid obstacles, and transmits the force of the wrench bar 4 to the torsion bar 2, so that the torsion bar 2 generates torsional force, that is, the force applied from a high place The thrust is transmitted as low torque, so that the oil filter nut 6 can be easily disassembled or installed, and the working environment has been greatly improved; among them: the locking threaded sleeve 3 is placed first figure 1 position, hold the spherical end 23 of the torsion bar 2, in...

Embodiment 2

[0031] On the basis of Embodiment 1, the upper and lower parts of the torsion bar 2 are respectively provided with a suspension external thread 22 and a locking external thread 21, and the end close to the suspension external thread 22 is provided with a spherical end 23, and the inside of the spherical end 23 is horizontal. There is a through hole 24, the wrench rod passes through the through hole 24 and is connected with the torsion bar 2, the hanging external thread 22 at the upper end can hang the locking thread sleeve 3; the locking external thread 21 at the lower end is used to lock the oil filter nut 6. The cylinder at the lower end fits with the fixing hole 11 in the arc claw 1 and is welded firmly; the wrench uses the length of the torsion bar 2 to avoid obstacles, and when the torsion bar 2 bears the torsion, the oil filter nut 6 can be rotated Tighten or loosen.

Embodiment 3

[0033] On the basis of Embodiment 2, the arc-shaped claw 1 is provided with a fixing hole 11, which is connected to the torsion bar 2, and the inner side of the arc-shaped claw 1 is equidistantly provided with claw teeth 12. The inclination of claw tooth part 12 is set to ∠3°, the arc-shaped claw 1 has good rigidity and large contact area, and the claw tooth part 12 is designed to be a 3° slope, which corresponds to the slope of the oil filter nut 6 tooth slots. It is beneficial to make the teeth contact tightly, reduce the contact gap, and facilitate the arc-shaped claw 1 not to slip out of the tooth groove of the oil filter nut 6 when torque is applied.

Abstract

The invention discloses an oil filter nut disassembling and assembling wrench. The oil filter nut disassembling and assembling wrench is used for disassembling and assembling a nut, and relates to thetechnical field of production tools. The wrench comprises an arc-shaped clamping jaw, a torsion bar, a locking threaded sleeve and a wrench rod, one end of the torsion bar is connected to the arc-shaped clamping jaw, the other end of the torsion bar is connected to the wrench rod, and the middle is in threaded connection with the locking threaded sleeve. The wrench is designed according to a maintenance operation tool, spatial position extension is carried out on the wrench clamping jaw, operation in a narrow space is converted into a free state of an open environment, the problem of disassembly and assembly of the oil filter nut is effectively solved, the magnitude of fastening force of the oil filter nut is guaranteed, a new method is provided for disassembly and assembly of the oil filter nut, and the nut which is positioned in a narrow space and has a plurality of obstacle interference parts is conveniently and quickly disassembled, so that the labor intensity is greatly reduced,the assembly efficiency is improved by multiple times, and the assembly quality is stable and reliable.

Description

technical field [0001] An oil filter nut dismounting wrench is used for dismounting nuts, and the invention relates to the technical field of production tools. Background technique [0002] The oil filter refers to the filter device for filtering hydraulic oil, which is generally composed of a shell and a filter element; installing a certain precision oil filter in the equipment is a necessary means to ensure the operation of the hydraulic system; the oil filter is widely used and has many varieties. , Large and medium-sized equipment, line-gap oil filters used on vehicles are composed of end caps, filter elements, nuts and cylindrical shells; during the recycling of equipment, oil will produce more particles, moisture, gas and other impurities , These impurities adhere to the filter element and block the filter element, so the filter element needs to be cleaned and replaced frequently. [0003] To replace the filter element, the oil filter nut needs to be removed. During t...
