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 was when processing some bent axle, and the branched crank-shaft link neck of frequent appearance is opened a grade face burn, hardening cracked phenomenon, even causes bent axle to scrap time serious.By analysis, find that subject matter is present in the cooling system of grinding machine.In existing cooling system structure, side nozzle is at the rear of main burner, and during correction emery wheel, side nozzle washes away abrasive wheel end face, and main burner and water main are Hard link.
Analyzing discovery after deliberation, there is following problem in this structure:
1. side nozzle is due to the below at main burner, and during grinding crankshaft connecting rod face, side nozzle cannot get around main burner and directly cool crankshaft connecting rod face;
2. open grade face at crank-shaft link neck and remove connecting rod neck size at the Breadth Maximum >=15mm(of radial direction, but comprise R size), crank-shaft link neck hardness higher and hardness number >=HRC46 time, grinding can produce amount of heat and can not take away in time, easily causes out a grade face burn, hardening cracks;
3. crankshaft grinding machine equipment is when processing different size bent axle, the grinding wheel diameter installed is also different, but main burner can not adjust with its change, causes cooling fluid not directly to be sprayed onto emery wheel and the tangent place of connecting rod neck, have impact on the cooling effect to connecting rod neck and end face.
Main burner joint of the prior art is Hard link, can not rotate adjustment, and the present invention uses bulb joint instead, then main burner can rotate, thus main burner just can adjust with supporting grinding wheel diameter change.After adjustment, cooling fluid directly can be sprayed onto emery wheel and the tangent place of 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) coordinates with steel part.Here fully take into account bulb can not frequently rotate, select will take into account low cost and versatility during raw material, bulb, nut and joint are all adopted 45# steel.
This invention is after coming into operation, and just never occurred that crank-shaft link neck was opened a grade face burn, hardening cracked phenomenon, crudy is stablized.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: to some crank-shaft link neck open grade face and the larger bent axle of R can fully cool, stop crank-shaft link neck to open grade face and occur phenomenons such as burning, hardening crack, ensure that qualification rate and the quality of product, for production obtains good economic benefit.
Summary of the invention
Goal of the invention of the present invention is: for above-mentioned Problems existing, provides a kind of novel cooling system of Large Crankshaft grinding machine, better cools the processing of crank-shaft link neck.
The technical solution used in the present invention is such:
A kind of novel cooling system of Large Crankshaft grinding machine, comprise the guard shield be arranged on above emery wheel, described guard shield front arranges main burner, between guard shield and main burner, former side nozzle is also set, described former side nozzle has two nozzles, and lay respectively at both sides, main burner rear, described main burner is connected with water main, described main burner front also arranges new side nozzle, and new side nozzle is connected with new water pipe.
As preferably, described new side nozzle has two nozzles, lays respectively at main burner both sides.
Increase side nozzle, open a grade face for directly cooling crank-shaft link neck, and the side nozzle newly added can not be interfered with main burner, emery wheel and balance weight, 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 the flow and the pressure that affect main burner simultaneously, therefore must increase separately a set of cooling system in main burner front, i.e. new side nozzle and new water pipe, for opening a grade face cooling.When increasing this cover cooling system, three-phase electricity pump lift and the flow of water supply must be considered, select suitable electric pump.
As preferably, realize being rotationally connected by bulb joint between described main burner and water main.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is the left view of Fig. 1.
Mark in figure: 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 is emery wheel, and 3-1 is bulb joint, and 3-2 is water main, and 4-1 is new water pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, 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, comprise the guard shield 1 be arranged on above emery wheel 6, described guard shield 1 front arranges main burner 3, also arranges former side nozzle 2 between guard shield 1 and main burner 3, and described former side nozzle 2 has two nozzles, lay respectively at both sides, main burner 3 rear, described main burner 3 is connected with water main 3-2, and described main burner 3 front also arranges new side nozzle 4, and new side nozzle 4 is connected with new water pipe 4-1.
Described new side nozzle 4 has two nozzles, lays respectively at main burner 3 both sides.
Realize being rotationally connected by bulb joint 3-1 between described main burner 3 and water main.
The new side nozzle 4 that the present invention increases, opens a grade face for what directly cool 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 burner 3 just can adjust with the diameter change of supporting emery wheel 6.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
