Description

Technical Field

[0001] The utility model belongs to the technical field of automobile assembly tools, and in particular relates to an electric gun tightening device for an automobile fuse box. Background Art

[0002] In addition to the mechanical part, the car also has a large number of electrical appliances. Its electronic control part connects various electrical appliances, just like the neural network of the car, and plays an important role. In the car's electronic control network, there is a fuse box, which contains fuses and relays, which play the role of fusing in extraordinary situations and protecting safety. This is crucial in cars, especially in the rapidly developing new energy vehicles. When installing the fuse box, you need to first connect the fuse and relay circuits in the fuse box, and then fix the fuse box to the engine compartment of the car with bolts. According to the process requirements, the tightening torque of the fuse box bolts must reach 9N·m. When fixing the fuse box, the operator needs to hold the box body with his left hand to fix the box body, and hold the electric gun with his right hand to tighten the bolts. When tightening the bolts, the fuse box will rotate under the action of the electric gun. At this time, the left hand should exert force to offset the rotational force caused by the electric gun on the fuse box to prevent the fuse box from rotating. Since the tightening torque of the fuse box bolts must reach 9N·m, the left hand must also exert relatively large force. Each fuse box needs to be screwed in with several bolts, and the operator has to assemble several fuse boxes every day, which will cause fatigue to the operator and damage to the operator's left hand. The fatigue of the operator will also affect work efficiency and product quality. Utility Model Content

[0003] The purpose of the utility model is to propose an electric gun tightening device for automobile fuse box in view of the problem that the existing automobile fuse box assembly process requires the operator to hold the fuse box and exert force to prevent the fuse box from rotating, which causes the operator's arm fatigue, affects work efficiency and product quality, etc. The device can prevent the fuse box from rotating when it is installed and fixed, and does not require the operator to exert force to offset the force of the fuse box rotation, thereby reducing the operator's fatigue and ensuring work efficiency and product quality.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0005] A car fuse box electric gun tightening device comprises an electric gun and a fuse box; the electric gun is provided with a screw twisting part; the fuse box is provided with a screw and a locking part; it also comprises a socket, a connecting socket, a locking rod and a locking piece; the middle part of the socket is provided with a socket hole; the electric gun is detachably connected to the socket through the socket hole; the side of the socket is detachably connected to the connecting socket; the locking rod is arranged at the bottom of the connecting socket; the locking piece is arranged at the end of the locking rod.

[0006] The function of the electric gun is to tighten the bolt through the screw twisting part; the fuse box is fixed to the interior of the car through the screw; the socket is detachably fixedly connected to the electric gun through the socket hole; the socket has replacement parts with different socket hole diameters for matching different electric guns; the locking piece is locked in the locking part of the fuse box, and the fuse box will not rotate when the screw is rotated.

[0007] As a further technical improvement, a slot is provided on the side of the connection seat, and an insert block matching the slot is provided on the side of the sleeve seat. The insert block is inserted into the slot to achieve connection and fixation between the sleeve seat and the connection seat.

[0008] As a further technical improvement, the slot and the insert block are both provided with corresponding screw holes, and the screw holes are matched with fixing screws, which can reinforce the connection and fixation between the sleeve and the connecting seat after being screwed into the screw holes.

[0009] As a further technical improvement, a rubber ring is provided on the inner wall of the sleeve hole of the sleeve, and the rubber ring plays a role in making the sleeve and the electric gun connected more tightly.

[0010] As a further technical improvement, the sleeve hole inner diameters of the sleeve seat have at least three sizes to match electric guns of different specifications.

[0011] As a further technical improvement, the front end of the locking piece is thinner than the rear end. Such a design makes it easier for the locking piece to be inserted into the locking portion, while also ensuring its strength.

[0012] As a further technical improvement, the front end of the electric gun is provided with a rotating shaft; the screw twisting part is detachably connected to the end of the rotating shaft; the screw twisting part matches the screw of the fuse box. The rotating shaft drives the screw twisting part to tighten the screw; the screw twisting part can be a screwdriver head, or a socket wrench, etc., which can be matched with a corresponding nut.

[0013] As a further technical improvement, the locking portion on the fuse box is a gap between two groups of raised or recessed parts fixedly connected to the fuse box. The locking portion is a gap between parts on the fuse box.

[0014] The method of using the above-mentioned electric gun tightening device for automobile fuse box:

[0015] When using, first select a suitable socket according to the model of the electric gun; connect the socket with the connecting socket, and put the socket on the electric gun; select a suitable screw knob according to the size of the screws on the fuse box; insert the locking piece into the locking part on the fuse box, turn on the electric gun, and tighten the fixing screw of the fuse box through the screw knob; at this time, since the locking piece is stuck in the locking part on the fuse box and the socket is connected to the electric gun, the fuse box will not rotate, and the operator only needs to straighten the fuse box by hand without using much force, so that the operator's hands will not get tired.

[0016] The technical solution of the utility model has the following beneficial effects:

[0017] 1. The utility model device inserts the locking rod and the locking piece into the locking part of the fuse box, so that the fuse box will not rotate when installed and fixed, and the operator does not need to exert force, thereby reducing the fatigue of the operator's hands.

[0018] 2. The socket of the device of the utility model can be replaced with different specifications according to the electric gun, and the screw twisting part can also be replaced with different styles according to the bolt, so that the applicability of the device is more extensive.

[0019] 3. A rubber ring is arranged in the sleeve hole of the sleeve of the utility model, so that the sleeve and the face of the electric gun are more firmly connected. BRIEF DESCRIPTION OF THE DRAWINGS
