Description
Technical field
The present invention relates to engine components abrasor technical fields, and in particular to a kind of adaptive mill of vertical crankshaft
Tool.
Background technique
Currently, crankshaft polishing cleaning equipment in the prior art is primarily present following several big problems: 1, existing crankshaft is beaten
Grinding machine is mostly artificial upper and lower pieces and workpiece transhipment, and the degree of automation is lower, occupies a large amount of human resources, 2, existing song
In transporting work pieces, the unit efficiency due to receiving grinding device limits axis sander, generally can only once complete one or two
The crankshaft of part is transported, and working efficiency is low, such as selects multiple devices, then takes up an area too big, can not meet the production requirement of production, and 3, existing
Each component layouts are unreasonable in some crankshafts polishing machine equipment, cause that equipment overall structure compactedness is poor, occupied area is larger, function
Rate consumption is more.
In view of the above-mentioned problems, China State Intellectual Property Office is disclosed, application No. is 201810165312.6 invention is special
Benefit, the patent include fixed plate, and station is fixedly connected at the top of the fixed plate, and the two sides of the fixed plate bottom are solid
Surely it is connected with supporting leg, the top of fixed plate and is located on the left of station and is fixedly connected with connecting plate, the bottom and position of fixed plate
Motor is provided between two supporting legs, the output shaft of motor is fixedly connected with gear, is provided at the top of gear and nibbles with gear
The tooth plate of conjunction, and the right end of tooth plate runs through supporting leg and extends to the outside of supporting leg.The present invention can be driven by the setting of motor
Gear rotation drives mobile bar and connecting rod mobile by the cooperation of gear and tooth plate, by the setting of connecting rod and adjustable plate,
It can drive clamping plate is mobile to carry out positioning process to workpiece by fixed link, while solve when carrying out polishing processing to workpiece
The problem of workpiece can not being positioned, workpiece is caused to shake, influencing polishing quality.
But the device also gradually exposes the shortcoming of technology with the use of production:
First, which is fixed crankshaft using two chucks, it is well known that, when small crank utilizes the machine
Structure may be implemented convenient for positioning, when encountering Large Crankshaft, be rotated using the concentricity that the fixed form not can guarantee crankshaft then,
So that easily shaking in its rotation process, grinding accuracy is influenced.
Second, when which is again fixed crankshaft using chuck, well known to week, crankshaft is held in practical work process
The radial force received, unbearable big axial force, when utilizing chuck when fixed to crankshaft, because of the opposite folder of chuck to be guaranteed
Holding force needs a big chucking power to act on the both ends of crankshaft, this bears crankshaft in big axial force, it is easier that
Crankshaft generates stress and concentrates, and influences installing and using for the later period of crankshaft, reduces the service life of crankshaft.
Third, when which again polishes to crankshaft using grinding head, since the big flour milling of crankshaft is in irregular shape, this
When allowing for that grinding head and crank shaft friction is needed to contact, it is limited to the irregular shape of crankshaft, so that often there is the portion of crankshaft
Divide polishing amount in surface excessive and the phenomenon of part of the surface polishing amount deficiency；If wherein polishing amount deficiency only needs to adjust grinding head
Carry out secondary polishing with the position of crankshaft, only take some time and labour, if but polishing amount is excessive, directly lead
Not being available for whole crankshaft is caused, leads to the generation of wasting phenomenon, improves production cost.
4th, wherein the width of grinding wheel is respectively less than the width of crankshaft burnishing part, this allows for needing to move back and forth polishing
It takes turns and polishes to the crankshaft surface to part, this just to need when several partial width differences occurs in a crankshaft
The displacement that adjust grinding wheel repeatedly increases the output of labour, and time-consuming more, reduces grinding efficiency.
5th, it is limited to the structure of grinding wheel, so that grinding wheel can only polish along the radial direction of crankshaft, works as needs
When polishing the side of crankshaft, it is also necessary to manually be polished using accessory, increase the output of labour, and effect of polishing
Rate is low.
It is crankshaft problem encountered during polishing processing above, wherein research staff is to surround how to protect
It under the premise of what card fastened is fixed crankshaft, polishes it, lacks the stressing influence having ignored to crankshaft；In order to realize right
When crankshaft face is polished, lacking not can guarantee the identical polishing amount in crankshaft face；And it when polishing the part of crankshaft different in width, needs
Frequently adjust displacement；And it is limited to grinding wheel, so that the phenomenon that manually carrying out auxiliary polishing by side wall of the accessory to crankshaft.
From the foregoing, it will be observed that the existing technology has inconveniences and defects in actual use, so it is necessary to be improved.
Summary of the invention
For the defects in the prior art, the present invention provides a kind of vertical crankshaft adaptive grinding tool, to solve tradition
Grinding tool in technology is the fastening guaranteed to crankshaft, lacks the stressing influence having ignored to crankshaft；In order to realize to crankshaft face into
