Description
Technical field
The utility model relates to the press technologies field, particularly a kind of crank throw formula stroke of a press stepless regulation structure.
Background technology
The crank throw formula stroke adjustable pressing machine path increment of domestic production at present all has level adjustable, and eccentric bushing is through locking gear locking, because installation dimension is fixed; The locking gear device can not be excessive, limited the number of teeth of locking gear, and the more adjustings naturally of locking number of teeth progression is many more; But the adjusting number of teeth is many; The size of each tooth reduces thereupon, and its locking tooth moment of torsion that can bear just can not meet the demands like this, so regulate the restriction that increasing of progression will receive harshness.After stroke adjustable pressing machine parameter was confirmed well, it is just fixing that it regulates progression, and path increment corresponding on its each governing stage is also fixed, and can not satisfy the adjusting requirement of more path increment like this, has lost the speciality of stroke adjustable flexibilityization.
The utility model content
The utility model to the adjustable requirement of stroke of a press amount stepless continuous, provides a kind of crank throw formula stroke of a press stepless regulation structure to prior art, makes the stroke of forcing press realize the stepless continuous adjusting; Simple in structure; Easy to adjust, the eccentric bushing reliable lock, degree of regulation is high.
The purpose of the utility model is to realize like this; A kind of crank throw formula stroke of a press stepless regulation structure; Comprise crank shaft, eccentric bushing and connecting rod; Said eccentric bushing is connected with crank shaft through the swelling cover, and said connecting rod and eccentric bushing outer planet are dynamically connected, and eccentric bushing one end periphery is provided with the hand-operated tools adjustment hole.
In the utility model; Eccentric bushing and crank shaft when needs adjusting slider path increment, only need unclamp the swelling cover through the swelling cover locking; Hand-operated tools is inserted the hand-operated tools adjustment hole; The switching eccentric bushing can relatively rotate eccentric bushing around crank shaft, and angle can be for arbitrarily angled in relative rotation, and the offset sum of eccentric bushing and the relative main rotating shaft of crank shaft is the half the path increment of slide block; The path increment of slide block can be regulated the not restriction of conditioned progression arbitrarily between maximum and minimum of a value.With respect to the mode that adopts the locking of side tooth, the adjusting progression of ram travel increases greatly, and adopts the locking mode of swelling cover, locks firm, easy to adjust.So compared with prior art the beneficial effect of the utility model is: the continuous stepless that can realize the press ram stroke is adjustable, and is simple in structure, easy to operate, locks solid and reliable.
As the further improvement of the utility model, the end face of said eccentric bushing is provided with the angle indicating dial, and the end face of the crank shaft corresponding with said eccentric bushing is provided with the arrow that is used to indicate angle.When adjustment stroke, eccentric bushing and crank shaft angle in relative rotation can show through the angle indicating dial, can conveniently control the angle of eccentric bushing rotation like this and converse the path increment of slide block, improve degree of regulation, practice thrift the adjusting time.
Another kind as the utility model improves, and said swelling is set on the end of eccentric bushing, is provided with cinch bolt in the swelling cover.When adjustment stroke, unclamp cinch bolt, the swelling cover is unclamped, eccentric bushing can relatively rotate around crank shaft, realizes the ram travel adjusting.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the sketch map of angle indicating dial.
Wherein, 1 swelling cover; 2 hand-operated tools adjustment holes; 3 eccentric bushings; 3.1 angle indicating dial; 4 support sets; 5 crank shafts; 5.1 arrow; 6 connecting rods; 7 swelling bolt spiral shells.
The specific embodiment
As shown be the crank throw formula stroke of a press stepless regulation structure of the utility model; Comprise crank shaft 5, eccentric bushing 3 and connecting rod 6; Eccentric bushing 3 is connected with crank shaft 5 through swelling cover 1; Crank shaft 5 is supported on the fuselage through support set 4, and connecting rod 6 is dynamically connected with eccentric bushing 3 outer planet, and eccentric bushing 3 one end peripheries are provided with hand-operated tools adjustment hole 2; The end face of eccentric bushing 3 is provided with angle indicating dial 3.1, and the end face of the crank shaft 5 corresponding with eccentric bushing 3 is provided with the arrow 5.1 that is used to indicate angle; Swelling cover 1 is arranged on the end of eccentric bushing 3, is provided with cinch bolt 7 in the swelling cover 1.
In the work, after swelling cover 1 is locked eccentric bushing 3 and crank shaft 5 are firmly locked, crank shaft 5 drives eccentric bushings 3 and rotates, and makes connecting rod 6 realize moving up and down around crank shaft 5 swings and drive slide block mechanism; When needs adjusting slider stroke, unclamp cinch bolt 7, swelling cover 1 is unclamped; The instrument of will starting inserts hand-operated tools adjustment hole 2 switching eccentric bushings 3 makes it relatively rotate around crank shaft 5, realizes the adjusting of ram travel, and eccentric bushing 3 can show through angle indicating dial 3.1 relative to the angle that crank shaft 5 rotates simultaneously; According to the changing value of this angle, can converse the path increment of slide block, when meeting the requirements of path increment; Adjusting finishes, and the cinch bolt 7 of screwing is with eccentric bushing 3 and crank shaft 5 lockings; Crank shaft 5 drives eccentric bushing 3 and rotates, and connecting rod 6 is realized normal ramming motion around crank shaft 5 swings and drive slide block mechanism.The utility model can well be realized the stepless continuous adjusting of the stroke of a press, and eccentric bushing locking is solid and reliable, and the ram travel degree of regulation is high, and is time saving and energy saving.
The utility model is not limited to the foregoing description; This implementation is with in the novel eccentric shaft connecting rod slider stroke control mechanism that also is applicable to other type; Every on the basis of the disclosed technical scheme of the utility model; Those skilled in the art does not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein according to disclosed technology contents, and these replacements and distortion are all in the scope of the utility model protection.
