Abstract
The utility model discloses a disassembling tool of a diesel injector, which comprises a connecting rod with one end connected with an oil injector. A striking hammer is sleeved on the connecting rod in a mode that the striking hammer can perform reciprocating slide along the axial direction, and a strike-resisting block is fixedly arranged at the other end of the connecting rod. When the disassembling tool is used, the strike-resisting block is struck by sliding the striking hammer, force is transmitted to the oil injector through the connecting rod after the strike-resisting block is stressed, and the oil injector is disassembled from an air cylinder cover after multiple repeated striking. The required disassemble time is only 10 minutes, the disassemble efficiency is improved greatly, and working intensity of workers is reduced. In addition, the operation is simple, the cost is low, the safety is high, and the practical applicability is strong.
Description
Technical field
The utility model relates to a kind of mechanical dismantling device, particularly a kind of instrument that is used to dismantle diesel injector.
Background technology
Carrying out diesel injector dismounting when maintenance, need fuel injector be extracted cylinder head, in the prior art, the method for dismounting fuel injector is: shown in accompanying drawing 1, main dependence turns nut and is pressed on the thrust plate, and screw rod moves upward and drives fuel injector and extract cylinder head.Because the mode that between fuel injector and the cylinder head is interference fit is fixedly connected, adopt the mode of nut rotation to apply power, effect is very limited; Dismounting maintenance time long (being about 40 minutes), efficient is extremely low, and fragile circumferential component; Maintenance cost is higher; Also exist master worker's labour intensity big, dangerous, shortcomings such as manufacturing cost height.
To above-mentioned deficiency, a kind of novel fuel injector extracting tool need be provided, it can be dismantled fuel injector fast, and also simple to operate, with low cost, practicality is wide.
The utility model content
In view of this, the purpose of the utility model provides a kind of extracting tool of diesel injector, with it diesel injector is dismantled, and can increase work efficiency, and reduces master worker's labour intensity.
The purpose of the utility model realizes through following technical scheme: a kind of extracting tool of diesel injector; Comprise the connecting rod that an end is connected with fuel injector; Be arranged with the mode that can reciprocatingly slide vertically on the connecting rod and impact hammer, the other end of connecting rod is set with the resistance piece.
Further, adopt engage thread to connect between said fuel injector and the connecting rod, connecting rod adopts locking nut to be fixedly connected with resisting between the piece, and locking nut and resistance piece are set to integrative-structure.
The beneficial effect of the utility model: the extracting tool of the diesel injector of the utility model; Comprise the connecting rod that an end is connected with fuel injector; Be arranged with the mode that can reciprocatingly slide vertically on the connecting rod and impact hammer, the other end of connecting rod is set with the resistance piece.During use; Impact hammering through slip and beat the resistance piece, resist the stressed back of piece and pass to fuel injector through connecting rod, repeated multiple times impacts; Can fuel injector be disassembled from cylinder head; Take-down time only needs 10 minutes, has improved removal efficiency greatly, and has greatly reduced workman's working strength; And it is simple to operate, with low cost, safe, practical.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the structural representation of existing diesel fuel injector extracting tool;
Fig. 2 is the structural representation of the utility model.
The specific embodiment
Fig. 1 is the structural representation of existing diesel fuel injector extracting tool; Fig. 2 is the structural representation of the utility model.As shown in Figure 2: the extracting tool of a kind of diesel injector of present embodiment; Comprise the connecting rod 2 that an end is connected with fuel injector 1; Connecting rod is fixedly connected with the screwed hole that is preset in the fuel injector top through the screw thread that is arranged on the end; Be arranged with on the connecting rod and impact hammer 3, impacting hammer 3 can be along pitman shaft to reciprocatingly sliding, and the other end of connecting rod 2 is set with resists piece 4.In the present embodiment, resist piece through being fixedly connected with connecting rod with its locking nut 5 that is set to one.
During use; Impact hammer through slip and clash into the resistance piece repeatedly, resist the stressed back of piece and pass to fuel injector through connecting rod, repeated multiple times impacts; Can fuel injector be disassembled from cylinder head; Take-down time only needs 10 minutes, has improved removal efficiency greatly, and has greatly reduced workman's working strength; And it is simple to operate, with low cost, safe, practical.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
