Definitions

  • the invention lies in the field of methods and tools for automotive mechanics and relates in particular to methods and tools for extracting glow plug rods from a vehicle engine, for example from a motor vehicle.
  • the glow plugs allow, when the engine is cold, to create a hot spot which increases the temperature of the combustion chambers and causes the fuel to ignite.
  • the spark plugs are also used to reduce smoke emissions at start-up and also participate during the post-combustion phase in the regeneration of the particle filter.
  • glow plugs comprise a metal body with a terminal at one end and a pencil at the other end.
  • the terminal corresponds to the free end of a central connection rod passing longitudinally through the spark plug to reach the rod.
  • the terminal is connected to the vehicle's electrical system.
  • the pencil includes a heating coil which extends partially into the combustion chamber. When the glow plug is energized, this spiral will heat up and thus heat up the combustion chamber.
  • the glow plugs are housed in the cylinder head of the engine.
  • the housing of each spark plug passes through the cylinder head from the outside to a combustion chamber. Since the glow plug rod is narrower than the body, the housing includes a lower part to house the rod and a wider part to house the body of the spark plug. The lower part forms a shoulder with the upper part, and opens onto the combustion chamber.
  • the housing part of the spark plug body comprises at its mouth an internal thread which allows the glow plug to be screwed into its housing. When the spark plug is worn out and needs to be changed, it is unscrewed from its housing from the outside. When unscrewing, it may happen that the glow plug breaks and the pencil gets stuck in its narrow seat. This break may appear at the level of the shoulder of the spark plug housing or else within the lower part of the housing.
  • the methods comprise a first step of drilling a bore in the rod by means of a drill of diameter smaller than the diameter of the rod, then a step of threading the bore by means of a tap, a step of screwing an extractor into the thread, and finally a step of extracting the pencil by removing the extractor screwed to the pencil.
  • the document DE202012008592 describes a two-part guide with a second guide threaded into a first guide, and which is put in place before the drilling step.
  • the first guide is first screwed into the thread of the spark plug housing, then the second guide slides into the housing of the spark plug body until it reaches the edges of the pencil housing.
  • the second guide is then fixed to the first using an Allen key and a tightening screw.
  • the second guide is hollow and allows the passage of the drill for the drilling step. So that the drill does not drill too far at the risk of weakening the pencil, or even breaking it, a ring is present around the shank of the drill. This ring is fixed at a certain distance from the drill using an Allen key and a tightening screw, giving it the freedom to drill the pencil correctly but preventing it from going too far.
  • the drilling step ends when the ring comes into abutment against the second guide.
  • the document DE 10 2007 025 745 A1 describes a method of extracting a glow plug when the glow plug is broken at the level of the mounting tube, that is to say the upper part of the glow plug. However, if the spark plug is broken at the bottom, then this process cannot recover a broken pencil from a glow plug.
  • the objective of the invention is to respond to at least one of the problems of the prior art by proposing a new method and tools for the extraction of a glow plug rod which are easy to use and can be used in an environment. bulky, suitable for any type of glow plug and which does not require prior adjustments.
  • the invention proposes a drill having a shoulder between the drilling part and its shank so that the latter can come into abutment against the shoulder. of the spark plug housing, indicating the end of drilling step a).
  • step a) can be carried out on any type of glow plug.
  • the drill bit can be driven into the glow plug housing even in a crowded engine environment.
  • the rod of the tap has a diameter greater than both the diameter of the tapping part so that the tap has a shoulder and both the diameter of the lower part of the housing, and the step b) thread comprises the thread of the bore until said shoulder of the tap is placed in abutment against the shoulder of the housing of the glow plug.
  • step b) thread comprises the thread of the bore until said shoulder of the tap is placed in abutment against the shoulder of the housing of the glow plug.
  • the tapping portion of the tap has the same length or a shorter length than the drilling portion of the tap.
  • the invention thus provides a complementary means of extracting the pencil.
  • a too short part of the pencil remains stuck in the lower part of the housing of the glow plug, it is not possible to pierce it in order to subsequently insert an extractor, at the risk of breaking it.
  • these steps of the extraction process do not require the installation of a bore.
  • steps f) and g) can be performed alternately between steps a), b), c) and d) when the broken rod stuck in the glow plug housing is too short.
  • the invention thus makes it possible, when it is not possible to remove the extractor because the end of the rod facing the combustion chamber is deformed and blocked, to recover the rod through another housing, in the occurrence of the injector housing.
  • This housing is advantageously wider than the housing of the spark plug and allows the deformed pencil to be easily passed.
  • the centralizer comprises an external thread complementary to an internal thread of the upper part of the housing and the centralizer is screwed to said internal thread when the centralizer is placed at the mouth of the upper part of the spark plug housing.
  • the set of tools further comprises a mass
  • the extractor comprises a rod, one end of which has a threaded head and the other end has a tip, said tip having a diameter greater than the diameter of the rod.
  • said mass is crossed on either side by a central channel comprising a diameter greater than the diameter of the rod of the extractor and less than the diameter of the tip of the rod.
  • the extractor comprises a rod, one end of which has a threaded head, said threaded head having a diameter less than the diameter of said rod, said end of the rod having a threaded bore and said threaded head being screwed into said threaded bore. of the rod.
  • the extractor of the invention avoids the initiation of fracture of the threaded head when screwing the tap into the threaded bore made in the rod, a break which would lead to the detachment of the threaded head from the rod.
  • the threaded head is here maintained along its length in the threaded bore of the extractor rod and is more resistant to forces.
  • the threaded head can also be replaced following wear.
  • the threaded head is in a material other than the rod, more preferably in a more rigid material.
  • the threaded head presents less risk of being separated from the body.
  • the tap comprises a tapping part and a shank
  • the shank of the tap has a diameter greater than the diameter of the tapping part so as to form a shoulder with the tapping part and is chosen to have a diameter greater than the diameter of the tapping part. diameter "d" of the lower part of the spark plug housing.
  • said tapping portion comprises flutes and combs and having an entry followed by a guide, said entry being an entry in GUN section in that at its level the flutes have a grinding stroke.
  • a GUN cut entry has the advantage of being a tapered entry which facilitates the centering of the tap relative to the bore during the tapping operation.
  • the shank of the tap has a diameter greater than the diameter of the tapping part so as to form a shoulder with the tapping part.
  • the tapping portion of the tap and the drilling portion of the drill bit have the same length.
  • the set of tools further comprises an expeller and a recuperator, said expeller comprising a rod with a head at one end, the diameter of the rod being greater than that of the head, and said recuperator comprising a magnetized part .
  • the magnetized part of the recuperator is connected to one end of a flexible rod. The flexible rod of the recuperator makes it easy to probe the inside of the combustion chamber to find the position of the pencil, and to recover it using the magnetic part.
  • the centering device is in the form of a cylinder crossed on either side in its longitudinal direction by a central duct.
  • the term “include” is synonymous with “include” and is not limiting in that it allows the presence of other elements in the device or the vehicle to which it relates. It is understood that the term “include” includes the terms “consist of”. In the various figures, the same references designate identical or similar elements.
