Abstract
The utility model provides a drive mechanism of planer ram, this mechanism of includes the ram, fixes ring gear, planetary gear, crank A, crank B, planetary gear and the meshing of fixed ring gear, crank A's one end and driving motor axle fixed connection, the other end is articulated with the planetary gear axle, planetary gear is last to have an eccentric shaft, crank B's one end is articulated with this eccentric shaft, and the other end is articulated with the ram. This transmission structure makes the reciprocating stroke speed of ram the same, and the planer tool of installing at the both ends of ram can carry out two -way planing to the work piece, and efficiency improves, its simple structure is convenient for maintain, and is easy and simple to handle, easy to assemblely uses on the planer.
Description
Technical field
The utility model relates to planer field, specifically a kind of ram transmission mechanism of planer two-way planing.
Background technology
The operation principle of existing planer makes to produce relative straight reciprocating motion between cutter and workpiece to surface of the work of planing, and is mainly used in the middle-size and small-size work pieces process of single and mini-batch production, planing out-of-plane, forming face and groove etc. on workpiece.The main motion of middle-size and small-size shaping machine, adopts crank and rocker mechanism transmission, large-scale shaping machine many employings hydraulic drive mostly.Because the backstroke speed of planer ram is greater than speed of working stroke, so usually adopt the processing of single-blade planing tool, when ram backhaul, planing tool does not cut, and productivity ratio is lower.
Summary of the invention
For the deficiency of above-mentioned background technology, provide a kind of transmission mechanism of planer ram, this transmission mechanism makes the reciprocating stroke speed of ram identical, makes the planing tool at ram two ends carry out double-end block plane to workpiece.
The technical solution of the utility model is: a kind of transmission mechanism of planer ram, this mechanism comprises ram, fixing ring gear, planetary gear, crank A, crank B, described planetary gear engages with fixing ring gear, one end of described crank A is fixedly connected with drive motors axle, the other end and planet pin hinged; Described planetary gear has an eccentric shaft, one end and this eccentric shaft of described crank B are hinged, the other end and ram hinged.
The two ends of described ram are separately installed with planing tool, and the edge direction of two planing tools is contrary.
The beneficial effects of the utility model are: this drive mechanism makes the reciprocating stroke speed of ram identical, and the planing tool installed at the two ends of ram can carry out two-way planing to workpiece, and efficiency improves; Its structure is simple, is convenient to safeguard, easy and simple to handle, is easily installed on planer and uses.
Accompanying drawing explanation
Fig. 1 is the structural representation of mechanism
Number in the figure is illustrated: 1-planing tool; 2-ram; 3-fixing ring gear; 4-planetary gear; 5-crank A; 6-crank B; 7-machine shaft.
Detailed description of the invention
As shown in Figure 1, a kind of transmission mechanism of planer ram, this transmission mechanism comprises ram 2, fixing ring gear 3, planetary gear 4, crank A5 and crank B6.
Described fixing ring gear 3 is circular internal gear, the output revolving shaft 7 of drive motors is provided with at ring gear 3 center, output shaft 7 is fixedly connected one end of crank A5, crank A5 is driven by drive motors, and the other end of crank A5 is hinged by the center of circle of hinge and planetary gear 4.
Described planetary gear 4 is arranged on in fixing ring gear 3, the tooth of planetary gear 4 engages with the tooth of ring gear 3, along with motor drives crank A5 one end to rotate, crank A5 will drive planetary gear 4 to rotate centered by drive motors output shaft 7 in fixing ring gear 3, this is the revolution of planetary gear 4, planetary gear 4 engages with ring gear 3, so also can rotate centered by the center of circle of self while its revolution, this is the rotation of planetary gear 4.
The wheel disc of described planetary gear 4 is provided with an eccentric shaft, and one end of eccentric shaft and crank B6 is hinged, and the other end and the ram 2 of crank B6 are hinged, and described ram 2 is provided with hinge, and the hinge on crank B6 and ram 2 is hinged; At planetary gear 4 time rotational, wheel disc rotates and drives crank B6, and crank B6 drives linear reciprocation ram 2 to move, and its reciprocal speed is consistent.
This transmission mechanism and planer are fitted to each other use, as the transmission mechanism of planer upper ram 2, planing tool 1 is separately installed with at ram 2 two ends, the edge direction of two planing tools 1 is contrary, the direction of planing tool 1 can adjust, and the linear reciprocating motion of ram 2, the planing tool 1 that ram 2 is installed can be made to realize the function of double-end block plane, plane in both sides simultaneously, its working (machining) efficiency is higher.
In this transmission mechanism, as long as the pitch circle size of appropriate design planetary gear 4, fixing ring gear 3 and the offset distance of planetary gear 4 eccentric shaft 7, the distance of crank B6 two coercive mechanism, the reciprocating motion of ram 2 can be realized, at this, concrete dimensional requirement is not repeated.And mechanism is also applicable to other mechanisms needing straight reciprocating motion uses.
