Abstract
The utility model discloses an engine crank dismounting device, which is characterized in that: the dismounting device comprises a punch head and a supporting device: A. the punch head (5) and a punch head rod (7) form an integral punch head device; B. a base (4) is connected to the bottom of a supporting base (2); a positioning plate (1) is positioned at the top of the supporting base to form a supporting device. The utility model can be adopted to conveniently dismount the engine crank with high working efficiency and without damaging the crank.
Description
(1). technical field
The utility model relates to a kind of extracting tool, particularly a kind of instrument that is used to dismantle engine.
(2). background technology
When the big end needle bearing of engine and crank-pin are done physico-chemical analysis, often need the left and right sides crank of dismounting engine.At present, often adopt hand saws and emery wheel that the engine crank-connecting rod combination is cut, the left and right sides crank with the dismounting engine makes by the damage of components of side engine, causes a large amount of wastes.
(3). summary of the invention
The purpose of this utility model provides a kind of engine crank provision for disengagement.It can dismantle engine crank easily, does not damage crank, and high efficiency.
For reaching above-mentioned purpose, the utility model provision for disengagement is made up of drift and supporting arrangement:
A. drift and plunger rod is holistic punch device;
B. the bottom of supporting base is connected with base, and the top is connected with location-plate and forms supporting arrangement.
Adopt the left and right sides crank of the utility model dismounting engine,, it is broken away from from engine crank-connecting rod combination 6, crank is separated with crankpin, therefore have easy to usely, do not damage the characteristics of crank with the crankpin on the drift punching engine.
Below in conjunction with accompanying drawing the utility model is described further.
(4). description of drawings
Fig. 1 is the structure diagram of the utility model supporting arrangement;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structure diagram of punch device;
Fig. 4 is a kind of embodiment of the present utility model.
(5). the specific embodiment
Provision for disengagement is made up of drift and supporting arrangement: referring to Fig. 3.Drift 5 is holistic punch device with plunger rod 7; Referring to Fig. 1,2.The bottom of supporting base 2 is connected with base 4, and the top is connected with location-plate 1 with screw 3 and forms supporting arrangement.Supporting base 2 tops are provided with open slot, and location-plate 1 is provided with open slot, and open slot is through to supporting base 2 bottoms from location-plate 1.
Referring to Fig. 4.When needs are dismantled the crank of engine, the engine crank provision for disengagement is placed on the hydraulic press platform, crankshaft disk in the engine crank-connecting rod combination 6 is placed in the open slot at supporting base 2 tops, drift is installed on the connecting pin at hydraulic press top, start hydraulic press, with the crankpin on the drift punching engine crank connecting link, crankpin is broken away from, from engine crank-connecting rod combination 6 even crank separates with crankpin.
Open slot on the location-plate 1 is identical with the open slot opening direction at bearing 2 tops, makes up with the convenient engine crank-connecting rod of installing.
Claims (5)
