Abstract
The invention discloses a novel cooling system for a large crankshaft grinding machine. The novel cooling system comprises a protective cover arranged above a grinding wheel, wherein a main nozzle is arranged in the front part of the protective cover and original-side nozzles are arranged between the protective cover and the main nozzle and are provided with two nozzles; the original-side nozzles are respectively positioned on the front and rear sides of the main nozzle; the main nozzle is connected with a main water pipe; a new-side nozzle is arranged in front of the main nozzle and is connected with a new water pipe. The novel cooling system has the beneficial effects that a gear opening surface of a certain crankshaft connecting rod neck and a crankshaft with relatively large R are fully cooled, phenomena such as burn injury and firing crack of the gear opening surface of the crankshaft connecting rod neck are prevented, the product qualification rate and the product quality are ensured and favorable economic benefits are achieved for production.
Description
Technical field
The present invention relates to crankshaft grinding machine technical field, particularly a kind of novel cooling system for Large Crankshaft grinding machine.
Background technology
In recent years, domestic Large Crankshaft grinding machine, when processing some bent axles, frequently occurs branched crank-shaft link neck and opens shelves
Face is burnt, is hardening cracked phenomenon, even causes bent axle to scrap when serious.Through analysis, find that subject matter is present in the cooling system of grinding machine
System.In existing cooling system structure, at the rear of main burner, when revising emery wheel, side nozzle washes away abrasive wheel end face, main jet to side nozzle
Mouth and water main are Hard link.
Through researching and analysing discovery, there is problems with this structure：
1. due to the lower section in main burner, during grinding crankshaft connecting rod face, it is outspoken that side nozzle cannot get around main jet to side nozzle
Connect cooling crankshaft connecting rod face；
2. open Breadth Maximum >=15mm in radial direction for grade face in crank-shaft link neck（Remove connecting rod neck size, but comprise R
Size）, crank-shaft link neck hardness is higher and during hardness number >=HRC46, grinding can produce amount of heat and can not take away in time, hold
Easily cause out a grade face burn, hardening crack；
3., when processing different size bent axle, the grinding wheel diameter of installation is also different, but main burner can not for crankshaft grinding machine equipment
It is adjusted with its change, cause coolant not to be directly sprayed onto the emery wheel place tangent with connecting rod neck, have impact on to connecting rod neck
Cooling effect with end face.
Content of the invention
The goal of the invention of the present invention is：For above-mentioned problem, provide a kind of the new cold of Large Crankshaft grinding machine
But system, the processing to crank-shaft link neck preferably cools down.
The technical solution used in the present invention is such：
A kind of novel cooling system of Large Crankshaft grinding machine, including the guard shield being arranged on above emery wheel, in front of described guard shield
Setting main burner, also sets up former side nozzle, described former side nozzle has two nozzles between guard shield and main burner, is located at master respectively
Nozzle rear both sides, described main burner is connected with water main, also sets up new side nozzle, new side nozzle is with newly in front of described main burner
Water pipe connects.
Preferably, described new side nozzle has two nozzles, it is located at main burner both sides respectively.
Increase side nozzle, open a grade face for direct cooling crank-shaft link neck, and newly plus side nozzle can not with main burner,
Emery wheel and balance weight are interfered, and therefore, side nozzle can only be added in the front of main burner.Joint due to former main burner does not increase
The space of side nozzle, also will avoid affecting the flow of main burner and pressure it is therefore necessary to individually increase in front of main burner simultaneously
A set of cooling system, i.e. new side nozzle and new water pipe, for opening a grade face cooling.When increasing this set cooling system it is necessary to consider
The lift of three-phase pump supplying water and flow, select suitable electric pump.
It is connected preferably, passing through bulb joint between described main burner and water main and realizing rotating.
Main burner joint of the prior art is that Hard link is adjusted it is impossible to rotate, and the present invention uses bulb joint instead, then main jet
Mouth can rotate, thus main burner just can be adjusted with the change of supporting grinding wheel diameter.After adjustment, coolant can be directly sprayed onto
The emery wheel place tangent with crank-shaft link neck, to connecting rod neck with open grade face and carry out good cooling.
Bulb joint high-abrasive material（As tin bronze）With steel part cooperation.Here fully take into account bulb will not frequently turn
Dynamic, select to take into account low cost and versatility during raw material, bulb, nut and joint are all adopted 45# steel.
, after coming into operation, just never crank-shaft link neck and opens a grade face burn, hardening cracks phenomenon, crudy in this invention
Stable.
In sum, due to employing technique scheme, the invention has the beneficial effects as follows：To some crank-shaft link necks
Open grade face and the larger bent axle of R can be sufficiently cool, prevented crank-shaft link neck and open grade face to occur burn, hardening cracking etc. phenomenon, guarantor
Demonstrate,prove qualification rate and the quality of product, obtain good economic benefit for production.
Brief description
Fig. 1 is the front view of the present invention.
Fig. 2 is the left view of Fig. 1.
In figure marks：1 is guard shield, and 2 is former side nozzle, and 3 is main burner, and 4 is new side nozzle, and 5 is crank-shaft link neck, and 6 are
Emery wheel, 3-1 is bulb joint, and 3-2 is water main, and 4-1 is new water pipe.
Specific embodiment
Below in conjunction with the accompanying drawings, the present invention is described in detail.
Embodiment：
As shown in Figure 1, 2, a kind of novel cooling system of Large Crankshaft grinding machine, including the guard shield being arranged on emery wheel 6 top
1, described guard shield 1 front setting main burner 3, also set up former side nozzle 2, described former side nozzle 2 between guard shield 1 and main burner 3
There are two nozzles, be located at main burner 3 rear both sides respectively, described main burner 3 is connected with water main 3-2, in front of described main burner 3
Also set up new side nozzle 4, new side nozzle 4 is connected with new water pipe 4-1.
Described new side nozzle 4 has two nozzles, is located at main burner 3 both sides respectively.
Pass through bulb joint 3-1 realization rotation between described main burner 3 and water main to be connected.
The new side nozzle 4 that the present invention increases, opens a grade face for direct cooling crank-shaft link neck 5.
The present invention adopts bulb joint 3-1 to connect water main 3-2 and main burner 3, then main burner 3 can rotate, thus main
Nozzle 3 just can be adjusted with the diameter change of supporting emery wheel 6.
