Description
Technical field
The present invention relates to the technical fields of clamping device, specifically disclose diesel engine cylinder block clamping device.
Background technique
Diesel-engine body group is mainly by groups such as gray iron, valve mechanism cover, Cylinder head gasket, main beating cap and oil sumps
At wherein diesel engine cylinder block is one of the core component of diesel engine work, the cleaning before quality and the cylinder body installation of block quality
Degree will have a direct impact on the quality of the working performance of later period diesel engine.
Therefore, before diesel engine assembling, it is necessary to which diesel engine cylinder block is clean.If there are miscellaneous in diesel engine cylinder block
Matter will lead to the piston abrasion of aggravation to diesel engine cylinder block when movement, influence the service life of diesel engine cylinder block.It is passing
During system cleaning diesel engine cylinder block, clamping diesel engine cylinder block does not have proprietary clamping device, if staff's needs pair
It when diesel engine cylinder block is cleaned, needs staff after having cleaned one side, needs manually to overturn diesel engine cylinder block,
Since diesel engine cylinder block is than heavier, there is staff's overturnings arduously, the low problem of cleaning efficiency.
Summary of the invention
It is arduously and clear to solve staff's overturning in background technique the invention is intended to provide diesel engine cylinder block clamping device
The problem of washing inefficiency.
To solve the above-mentioned problems, base case of the invention is as follows:

The two sidewalls of upper chamber are equipped with the hole for water spraying for the setting that is staggered, and hole for water spraying is communicated with high-pressure hydraulic pump towards gasoline engine, hole for water spraying；
The bottom chamber is equipped with reflux portion, and reflux portion includes piston case, and level slidably connects piston block in piston case,
Piston block level is connected with piston rod, and the connecting pin of the second clamping part and first partition through first partition and is connected with fan tooth
Wheel, elevating arc level are engaged with spur rack, elastic component are connected between spur rack one end and lower chambers side wall, spur rack is far from bullet
Property part one end is affixed on the piston rod；
Side wall on the piston case far from piston rod is equipped with the first drainpipe and water inlet pipe, is equipped at the top of upper chamber
Aquaporin is connected between the first drainpipe and exhalant canal, and one-way water inlet valve is equipped in water inlet pipe, is equipped in the first drainpipe single
To drain valve.
The working principle of this base case and the utility model has the advantages that
1. high pressure water sprays from hole for water spraying, apply certain active force to cylinder body, so that cylinder body rotates.Rotation
Cylinder body drives the rotation of the second clamping part, elevating arc rotation is driven, in addition spur rack does reciprocating linear fortune under the action of elastic component
It is dynamic, and then push piston block linear reciprocating motion in piston case.Piston case move back and forth during, piston case by into
Water pipe inwardly absorbs water, and then by hydraulic pressure to the first drainpipe, and persistently presses to exhalant canal, sprays from upper chamber top, right
It is cleaned at the top of cylinder body.
2. base case is suitable for semienclosed diesel engine cylinder block, i.e., from the outer feelings for being observed that cylinder interior
Condition.This base case drives the rotation of cylinder body using the surge of high pressure water, when cylinder body rotation, to the appearance of cylinder body
Face and inner surface are cleaned, and provide overturning power, energy saving use without additional power source for cylinder body.
3. during rotation, under the cooperation by elevating arc, spur rack and elastic component, so that piston block is in piston
Move back and forth, sucking water back and forth carries out the operation then by hydraulic pressure to the exhalant canal of clamping box top, to the top of cylinder body into
Row elution.The energy is further saved also with the pressure of high pressure water without additional power source to the elution at top
It uses.
4. base case rotates cylinder body using the pressure of high pressure water, work without manually rotating to cylinder body
It is more laborsaving to make personnel, also, multiple clamping devices can be placed in factory, while multiple cylinder bodies are cleaned, improves clear
The efficiency washed.
5. base case utilizes the first clamping part being oppositely arranged, the second clamping part respectively to the top of cylinder body, bottom
It is clamped, also, the first clamping part can also be vertically movable, it is practical to be adapted to the size of different size rigid bodies.
Further, first clamping part includes the first vertically arranged supporting rod, and first supporting rod one end is through clamping
Case upper surface, the first supporting rod other end are connected with the first grip block, and the first grip block is equipped with several pin holes, in pin hole
It is combined with bolt.
Bolt can be matched with the hole of cylinder body, and insertion bolt is held fixedly cylinder body more in the first clamping part and the
Between two clamping parts, prevent when cylinder body rotates, cylinder body is deviate from from the first clamping part and the second clamping part.
Further, the bottom chamber is vertically connected with second partition, and lower chambers are divided into first chamber by second partition
And second chamber, reflux portion are mounted in second chamber, are connected with horizontally disposed filter screen in first chamber, filter screen is by
One chamber is divided into non-filtering chamber and filtering chamber, and filter chamber is communicated with the second drainpipe, and the second drainpipe is communicated with
Wastewater treatment case, first partition are equipped with the waste water hole of connection upper chamber and non-filtering chamber.
The waste water after cylinder body will be cleaned to be filtered and purified treatment, the water of purified treatment is utilized again
Come, saves water resource, reduce the cost of cleaning.
Further, second clamping part includes the second supporting rod, and the second supporting rod upper end is connected with ratchet, upper chamber
Inner wall is hinged with the pawl engaged with ratchet.
Ratchet and pawl can prevent cylinder body from inverting, and avoid cylinder body from inverting so that reducing cleaning efficiency.
Further, the body structure that the clamping case is surrounded by top plate and bottom plate and opposite sides plate, opposite both side plate point
It is not hinged with the observation door and door close of closing opening vertically, is equipped in door close with both the first drainpipe, exhalant canal even
