Description

Engine harness buckle dismounting tool

Technical Field

The utility model relates to a pencil buckle frock technical field relates to an engine harness buckle dismantles frock especially.

Background

Automotive wiring harnesses are important components of automotive circuitry for transmitting various control signals between various components of an automobile and forming a complete control system. Along with the coming of the national sixth-stage motor vehicle pollutant emission standard, the wire harness of an engine product is continuously upgraded, and a tail gas emission control sensor, an actuator and a corresponding fixed wire harness buckle are added, so that the quantity of the wire harness buckle is greatly increased. Major repair is used as an important means for ensuring delivery after research, development, verification and mass production in a factory, and each part of an automobile needs to be checked, so that the disassembly of the wire harness is involved, and the wire harness buckle for fixing the wire harness needs to be disassembled firstly. How to fast and perfectly demolish six wire harnesses in state and corresponding pencil buckle will directly influence the research and development and the product delivery of six projects in state, guarantee simultaneously that maintenance efficiency and cost of maintenance satisfy annual plan.

At present, no special tool is used for disassembling the wiring harness buckle in actual operation, and the wiring harness buckle is clamped by using a hand vice and is pulled out forcibly. Because the wire harness buckle is usually sleeved on the external stud, the contact between the wire harness buckle and the stud is enhanced when the wire harness buckle is clamped by the pliers, and the friction between the wire harness buckle and the stud is very large due to the external thread of the stud, so that the wire harness buckle is difficult to pull out. Meanwhile, the wire harness buckle is very easy to damage when the wire harness is pulled out forcibly.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in attached drawings fig. 1-3, the utility model provides a pair of frock is dismantled to engine wiring harness buckle, including support 3 and frock nut 2, the top of support 3 and frock nut 2's side fixed connection, the bottom side of support 3 is extended to have and is horizontally first jack catch 31 and second jack catch 32, has space 33 between first jack catch 31 and the second jack catch 32, and space 33 is just right from top to bottom with frock nut 2's screw, has inserted frock screw 1 in the screw.

Specifically, as shown in fig. 3, the wire harness buckle 5 is fixed on a fixing stud 6 of an engine in actual use, and specifically, the wire harness buckle 5 is sleeved on the fixing stud 6. When the tool screw 1 is disassembled, a part of the tool screw is screwed upwards; then, the bracket 3 is held by hand, a gap 33 between a first claw 31 and a second claw 32 at the bottom of the bracket 3 is aligned to the fixing stud 6, the first claw 31 and the second claw 32 are inserted below the wiring harness buckle 5, and at the moment, the fixing stud 6 is positioned in the gap 33 and the top of the fixing stud is opposite to the bottom of the tool screw 1; then, the tool screw 1 is rotated to move downwards until the bottom of the tool screw contacts with the top of the fixing stud 6 and continues to rotate, the tool screw 1 is blocked by the fixing stud 6 and cannot continue to move downwards, but with the further rotation of the tool screw 1, the bracket 3 cannot rotate because the bracket 3 is held by hands, the whole of the tool nut 2, the bracket 3, the first jaw 31 and the second jaw 32 moves upwards relative to the tool screw 1 and the fixing stud 6, and the wire harness buckle 5 is pulled out of the fixing stud 6 upwards through the first jaw 31 and the second jaw 32; and finally, screwing out the tool screw 1 upwards to take down the wiring harness buckle 5.

It should be noted that the size of the screw hole of the tool nut 2 and the diameter of the tool screw 1 need to be matched with the sizes of the harness buckle 5 and the fixing stud 6, specifically, in the process of pulling out the harness buckle 5, the harness buckle 5 is transferred from the fixing stud 6 to the tool screw 1, so the diameter of the tool screw 1 cannot be larger than the diameter of the inner hole of the harness buckle 5 and the diameter of the fixing stud 6. In order to reduce friction with the tool screw 1 when the wire harness buckle 5 is transferred, the diameter of the tool screw 1 is preferably smaller than the diameter of the inner hole of the wire harness buckle 5 and the diameter of the fixing stud 6.

Meanwhile, the size of the gap 33 should be larger than the diameter of the fixing stud 6 and smaller than the outer diameter of the fixing end of the wire harness buckle 5, so that the first jaw 31 and the second jaw 32 can be inserted into the lower part of the fixing end of the wire harness buckle 5 and pulled out.

In one embodiment, the projection of the threaded bore of the tool nut 2 in the vertical direction falls completely within the confines of the void 33.

Specifically, the improvement enables the tool screw 1 in the screw hole of the tool nut 2 to be completely and accurately aligned with the fixing stud 6 when the tool is used.

In one embodiment, the ends of the first jaw 31 and the second jaw 32 are each in a pointed shape with a gradually decreasing thickness in the vertical direction.

Specifically, when the actual harness buckle 5 is sleeved on the fixing stud 6, there may be a problem that a gap between the bottom of the harness buckle 5 and the engine housing is small, which makes it difficult to insert the first jaw 31 and the second jaw 32, so that the ends of the first jaw 31 and the second jaw 32 are designed to be sharp, so that the gap can be conveniently inserted below the harness buckle 5.

In one embodiment, the first jaw 31 and the second jaw 32 are both arc-shaped and form a horizontal incomplete circle.

In one embodiment, the junction between the top surfaces of the first jaw 31 and the second jaw 32 and the inner side surface near the gap 33 is a cambered transition.

Specifically, the above improvement aims to change the edge angle of the inner side of the upper portion of the first jaw 31 and the second jaw 32 into a cambered surface when the first jaw 31 and the second jaw 32 are lifted relative to the fixing stud 6, so that the edge angle and the thread on the fixing stud 6 are prevented from being mutually clamped.

In one embodiment, the bottom end of the tool screw 1 is conical and the conical top is a circular arc surface.

Specifically, the conical top reduces the contact area between the tool screw 1 and the fixing stud 6, so that the friction force of the contact surface is reduced, and the influence of rotation of the fixing stud 6 and the tool screw 1 is reduced. Meanwhile, the conical top is an arc surface, so that the fixing stud 6 is prevented from being damaged due to the fact that the conical top is sharp.

In one embodiment, a cylindrical rotating operation block 4 is attached to the top of the tool screw 1.

Preferably, two opposite side surfaces of the rotating operation block 4 are provided with spare screw holes 41.

Specifically, the rotating operation block 4 facilitates the operation of the tool screw 1 by the operator. Meanwhile, according to actual requirements, another screw rod can be screwed into the standby screw hole 41, and the operation of rotating the tool screw rod 1 is further facilitated.
