The utility model discloses can reduce the intensity of labour of car pencil bonding technology, the guarantee removes lacquer membrane effect, has advantages such as simple structure, convenient to use, work efficiency height, low cost.
Description
Technical field
The utility model relates to Trend of Auto Manufacturing Technologies field, concrete refers to a kind of dead axle heart end face grinding abrasive disk instrument.
Background technology
Automotive electrical system adopts one wire system more at present, and the negative pole of automotive electrical system should be connected with the metal surface of vehicle frame or car body, is commonly called as " minus earth ".For the vehicle frame or the car body that complete coating process, need to remove the paint film of vehicle frame or car body surface, make car load wire harness can with the metal surface UNICOM of vehicle frame or car body, if removing, paint film thoroughly can not cause bunch bonding bad, especially battery and engine bonding wire harness, if paint removal position can not be covered completely by pad or bolt simultaneously, can cause metal surface exposed in wet environment and the phenomenon that occurs getting rusty, when serious, can cause local electrical resistance sharply to increase, cause ground strap hot-spot,, even there is burning the serious consequences such as vehicle in the wire harness that ignites.
The method of existing removal vehicle frame or car body surface paint film has multiple, common are toothed washer or attacks line bolt and pierce through method and manual grinding and the method such as remove.Pierce through the method for paint film, although technique is fairly simple, saw shape pad or attack the feature that line bolt must possess high rigidity and high rigidity, otherwise they can deform and cannot pierce through paint film, cause loose contact, and cost significantly increases simultaneously.Although the method for manual grinding coating removal film is simply effective, there are the following problems for existing grinding wheel: there is no positioning shaft device, inconvenient operation; Paint removal membrane area, flatness are unstable, polishing except painting quality poor.
Summary of the invention
For above-mentioned defect, the purpose of this utility model will provide a kind of exactly can effectively remove vehicle frame or car body region of interest paint film, guarantees the dead axle heart end face grinding abrasive disk instrument of the effective bonding of vehicle electrical systems negative pole.
For achieving the above object, the utility model provides a kind of dead axle heart end face grinding abrasive disk instrument, comprises the emery wheel with central through hole, it is characterized in that: also comprise spanner, in the central through hole of described emery wheel, be arranged with locating shaft; One end of described locating shaft is provided with guide head, and the other end of locating shaft is provided with locating hole, and described spanner is connected with locating hole.
As a kind of preferred version, when described spanner is pneumatic impact spanner, described locating hole is square hole.
As another kind of preferred version, when described spanner is electric wrench, described locating hole is regular hexagon hole.
Further, be also provided with the alignment pin matching with described locating hole.
The utility model has the advantage of: the utility model is simple in structure, easy to use, operating efficiency is high, with low cost, adopt this instrument, can at vehicle frame or car body surface, take installing hole as the center of circle easily, paint film in specific circle ring area is polished off, can guarantee that wire harness is effectively connected with vehicle frame ground, bunch bonding joint can cover paint film completely simultaneously, avoids vehicle frame or car body corrosion.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Dead axle heart end face grinding abrasive disk instrument as shown in Figure 1, comprises the emery wheel 1 with central through hole, it is characterized in that: also comprise spanner, be arranged with locating shaft 2 in the central through hole of emery wheel 1; One end of locating shaft 2 is provided with guide head 3, and the other end of locating shaft 2 is provided with locating hole 4, and spanner is connected with locating hole 4.
When spanner is pneumatic impact spanner, locating hole 4 is square hole, is also provided with the alignment pin 5 matching with locating hole 4; When spanner is electric wrench, locating hole 4 is regular hexagon hole.
In the utility model, the diameter of locating shaft 2 is identical with wire harness set bolt nominal diameter D, and locating shaft end face guide head 3, is convenient to quick location; The diameter of cylinder emery wheel 1 is slightly less than or equals the opposite side S of wire harness clamp nut, makes worn paint film can guarantee that wire harness is effectively connected with vehicle frame or car body, avoids worn region excessive simultaneously, causes bad; Locating hole 4 can directly be connected with pneumatic impact spanner 6, by electric wrench 7 twisting alignment pins 5, drives emery wheel 1 work.
During use, by under guide head 3 auxiliary, by in locating shaft 2 quick insertion wire harness construction bolt holes, the working face of emery wheel 1 and vehicle frame 8 or car body surface are firmly compressed, locating hole 4 tail ends of emery wheel 1 are connected with pneumatic impact spanner 6, or by alignment pin 5, make emery wheel 1 under electric wrench 7 drives, take locating shaft 2 as center of circle rotation, the vehicle frame 8 or the car body surface paint film that contact with emery wheel 1 working face are polished off.
