Abstract
The utility model provides a balancing machine of a crankshaft, including a driving device and two bearings for supporting the crankshaft, each bearing is composed of two friction wheels which are adjacent to each other, the axial cords of the two friction wheels are parallel, and the friction wheels are of a V shape. The balancing machine is capable of meeting the requirement to the measurement of the crankshaft balancing precision, and greatly improving balancing efficiency of the crankshaft.
Description
Technical field
The utility model relates to a kind of crank balancing machine.
Background technology
Along with developing of automobile industry, the auto parts and components industry is greatly improved, and the production as the bent axle of one of most important part of motor car engine is also had higher requirement, the effect of the balancing processing of bent axle will directly have influence on the quality of whole engine.Bad as counterbalance effect, will the noise of engine be improved greatly, reduce serviceable life greatly.Therefore being badly in need of one can satisfy crankshaft counterbalance efficient, can satisfy the equipment of the requirement of balance quality again.As adopting automatic crank balancing machine, cost height (equipment nearly 1,500,000 yuan) requires high (big as the workpiece initial unbalance,, machine will be reported to the police) to workpiece simultaneously.Workpiece preliminary working simultaneously must be handled through mass centering.Traditional equilibrator, workpiece drives and is universal joint, two kinds of forms of belt drives, special rotor also can adopt Electromagnetic Drive and air stream drives, and the balance workpiece is a bent axle, only be applicable to universal joint and belt drives, more than two kinds of forms all need workpiece in equilibrium process, to make unit clamp by universal joint, or workpiece is by the belt suit, inefficiency, and the going heavily of workpiece (amount of unbalance is measured the back) will be torn another process equipment open from equilibrator and gone to heavy back heavily to examine moving equilibrator to, and it is lower to cause processing beat.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of crank balancing machine, and it improves crankshaft counterbalance efficient when satisfying crankshaft counterbalance precision measure requirement.
In order to address the above problem, the crank balancing machine that the utility model provides, comprise drive unit and two supporting bases that are used to support bent axle, described each supporting base is made of two friction pulleys, described two friction pulleys mutually near and axis parallel, form a V-type groove between two friction pulleys.The axle journal of bent axle is stuck in this V-type groove, axle journal and two tangent contacts of friction pulleys difference.
Preferably, described drive unit comprises drive motor and transmission shaft, be in transmission connection by synchronous band between drive motor synchronous pulley and the transmission shaft synchronous pulley, drive pulley also is housed on the described transmission shaft, described drive pulley and the transmission shaft synchronous pulley is coaxial is connected, described drive pulley and two driven pulleys constitute band transmissions synchronously, two friction pulleys respectively with described two coaxial being connected of driven pulley.
Further, described drive pulley is two, and described driven pulley is two pairs.
Crank balancing machine of the present utility model adopts friction pulley to replace universal joint and belt drives, and crankshaft workpiece need not special clamping, can carry out balancing a survey, when satisfying crankshaft counterbalance precision measure requirement, has improved crankshaft counterbalance efficient greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the left view of this Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be specified.
Crank balancing machine as depicted in figs. 1 and 2, comprise drive unit and two supporting bases that are used to support bent axle, each supporting base is made of two friction pulleys 5, two friction pulleys 5 mutually near and axis parallel, form a V-type groove between two friction pulleys 5, two supporting bases have two V-type grooves, and two axle journals 10 of bent axle 6 are stuck in two V-type grooves, each axle journal 10 and every pair of friction pulley 5 tangent contacts.Drive unit comprises drive motor 1 and transmission shaft 2, between drive motor synchronous pulley 8 and the transmission shaft synchronous pulley 9 by being with 3 to be in transmission connection synchronously, two drive pulleys 7 also are housed on the transmission shaft 2, each drive pulley 7 and transmission shaft synchronous pulley 9 coaxial being connected, each drive pulley 7 and two driven pulleys 4 constitute band transmission synchronously, two friction pulleys 5 respectively with two driven pulleys, 4 coaxial being connected.
During work, motor 1 is by after being with 3 to slow down synchronously, drive intermediate propeller shaft 2 rotations, then drive drive pulley 7 rotations, drive pulley 7 drives driven pulley 4 rotations, and driven pulley 4 drives friction pulley 5 rotations, and friction pulley 5 contacts with the axle journal 10 of bent axle 6 again, thereby drive bent axle 6 rotations, realize the purpose of balancing a survey.
Structure of friction wheel has been adopted in the supporting and the driving of crankshaft workpiece, after workpiece is placed on the equilibrator, does not need special clamping, directly press start button, can carry out balancing a survey, after measurement finishes bent axle, move and remove drilling machine, work supporting block rises, and workpiece is held up, carry out craft or remove weight automatically, after going heavily to finish, work supporting block descends, workpiece is descended, start the main shaft button then, the reinspection of march shaft-like work, workpiece need not special clamping, has improved efficient greatly.
The effect of the utility model structure is: when taking into account the crankshaft counterbalance precision measure, improved the efficient of crankshaft counterbalance technology greatly.
More than just utility model has been carried out exemplary explanation, specific implementation of the present utility model is not limited thereto.The insubstantial modifications that any employing design of the present utility model and technical scheme are carried out is all within protection domain of the present utility model.
