Abstract
The utility model relates to design and application of an auxiliary tool for machine processing, belonging to the field of machine processing, in particular to an auxiliary device for dynamic balance gear shaving. Actually, a balance shaft is subjected to counter weight treatment, so that the rotation of the balance shaft during gear shaving can acquire dynamic balance. According to a principle, a corresponding counter weight device is designed according to the shape of the balance shaft, the auxiliary device comprises a gear face positioning fixture 1 and the counter weight device 2, the gear face positioning fixture 1 is a round ring, a copper-based lining 6 is arranged at the position of an inner ring and is used for protecting an outer circle of a workpiece 7 from being damaged, a locking screw 4 is arranged on the surface of the outer circle and is used for completely connecting the workpiece 7 and the counter weight device 2 into a whole, the counter weight device 2 is of a concave shape, one end of the counter weight device 2 and the gear face positioning fixture 1 are fixedly connected via a set screw 3, the other end of the counter weight device is provided with a positioning pin 5, and the positioning pin 5 is used for inserting the workpiece 7 into the counter weight device 2. The auxiliary device has the advantages that the rotation of the balance shaft during gear shaving can acquire dynamic balance, additional dynamic pressure and periodic mechanical vibration are reduced, damage of imbalance caused by the workpiece during gear shaving on equipment and a cutter is effectively eliminated or reduced, and the service lives of the equipment and the cutter are prolonged, and the quality of gear shaving is improved.
Description
Technical field
The utility model relates to the design and use of machining auxiliary mould, belongs to field of machining, a kind of more precisely servicing unit of dynamic balancing shaving processing.
Background technology
At ask for something in the higher or high speed engine; Generally be furnished with trunnion shaft with the on-stream imbalance that causes of balance crankshaft parts, thus the shake of eliminating or alleviating engine and even car load, but trunnion shaft itself is an extremely unbalanced part; In process especially in shaving processing; Process because of adopting thimble to push up folder two centre bores, trunnion shaft because of self action of centrifugal force, causes that thimble supports the additional dynamic pressure and periodicity mechanical shock in (precision bearing) in rotary course; The injury that thimble and supporting mechanism thereof and razor are caused is bigger, and the profile accuracy of being processed can not get guaranteeing.For effectively eliminating or alleviating the shaving process because of the infringement of the imbalance of workpiece to the said equipment, cutter, increase the service life, improve the quality of shaving processing, workpiece rotates and is able to dynamic balancing in the time of must managing to make shaving.
The utility model content
The purpose of the utility model is to overcome above-mentioned weak point, and a kind of servicing unit of dynamic balancing shaving processing is provided.
The utility model is for achieving the above object; Adopt following technical measures to realize: a kind of servicing unit of dynamic balancing shaving processing, it comprises face of gear positioning fixture and counter weight device, said face of gear positioning fixture is an annulus; Its endocyclic position is provided with copper base lining; Be used to protect the cylindrical of workpiece injury-free, outer round surface is provided with lock-screw, is used for workpiece and counter weight device are connected into an integral body fully; Said counter weight device is a concave character type, and an end is fixedly connected through fixed screw with the face of gear positioning fixture, and the other end is provided with alignment pin, is used for the workpiece counter weight device of packing into.
Said copper base lining is stepped.
Said fixed screw is preferably two.
The beneficial effect of the utility model is: the rotation of trunnion shaft is able to dynamic balancing when making shaving; Additional dynamic pressure and periodic mechanical vibration have been reduced; Effectively eliminate or alleviate the shaving process because of the infringement of the imbalance of workpiece to equipment, cutter; Prolong the service life of equipment, cutter, improved the quality of shaving processing.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further elaboration;
Accompanying drawing 1 is the main TV structure sketch map of the utility model;
Accompanying drawing 2 is the right TV structure sketch map of the utility model;
Accompanying drawing 3 is the plan structure sketch map of the utility model;
Accompanying drawing 4 is installed the dynamic poise device design sketch for the utility model workpiece;
1. face of gear positioning fixtures, 2. counter weight devices, 3. fixed screws, 4. lock-screws, 5. alignment pins, 6. bronze medal base linings, 7. workpiece among the figure.
The specific embodiment
Like the servicing unit that Fig. 1, Fig. 2, Fig. 3, a kind of dynamic balancing shaving shown in Figure 4 are processed, actual is trunnion shaft to be carried out counterweight handle, and the rotation of trunnion shaft is able to dynamic balancing when making shaving.Principle is: according to the corresponding counter weight device of the shaped design of trunnion shaft; It comprises face of gear positioning fixture 1 and counter weight device 2; Said face of gear positioning fixture 1 is an annulus, and its endocyclic position is provided with copper base lining 6, is used to protect the cylindrical of workpiece 7 injury-free; Outer round surface is provided with lock-screw 4, is used for workpiece 7 and counter weight device 2 are connected into an integral body fully; Said counter weight device 2 is a concave character type, and an end is fixedly connected through fixed screw 3 with face of gear positioning fixture 1, and the other end is provided with alignment pin 5, is used for workpiece 7 counter weight device 2 of packing into.
During use copper base lining 6 is pressed in the face of gear positioning fixture 1; Again that face of gear positioning fixture 1 is fixing with counter weight device 2 usefulness fixed screws 3; With workpiece 7 through alignment pin 5 counter weight device 2 of packing into; The lock-screw 4 of screwing connects into an integral body fully with workpiece 7 and counter weight device 2, and the workpiece 7 of packing into carries out shaving processing again and gets final product.
The rotation of trunnion shaft is able to dynamic balancing when using the utility model to make shaving; Additional dynamic pressure and periodic mechanical vibration have been reduced; Effectively eliminate or alleviate the shaving process because of the infringement of the imbalance of workpiece to equipment, cutter; Prolong the service life of equipment, cutter, improved the quality of shaving processing.
