Abstract
The invention discloses a lifting mechanism which comprises a motor, an output shaft driven by the motor and an eccentric shaft fixedly arranged on the output shaft. The eccentric shaft rotating around the output shaft pushes connecting rods on two sides to reciprocate to drive sliding bases on two sides to slide synchronously in reciprocating mode so as to drive hinged joints of first supporting arms and the sliding bases to slide in linear and reciprocating mode between the hinged joints and a hinged joint of a second supporting arm and a support, supporting points at the upper ends of the first supporting arms of lifting frames on two sides can keep parallel, synchronous and vertical lifting, and bearing surfaces which are supported on the first supporting arms on two sides and used for bearing springs can lift parallelly and vertically. When a manipulator grabs the springs, accurate control can be achieved, and operation stability of an automatic production device is guaranteed.
Description
Technical field
The present invention relates to lifting equipment technical field, specifically relate to a kind of carrying surface mechanism of vertical lifting in parallel that makes.
Background technology
In spring chair production industry, enterprise requires more and more higher to the automation of equipment and mechanization.While producing spring chair net, conventionally the spring string of the row of being arranged in a row need to be formed to pad net, traditional pad net string knot technique is first by manually single spring being placed into net sewing machine station one by one, then by net sewing machine, spring is chained together, thereby group is formed pad net.For the feature of spring chair production technology, a kind of optimizing design scheme is: first that the spring rows of being spooled moulding by spring coiling machine is in a row, and then by manipulator in a row, whole row's spring is pinched on net sewing machine station together.In order to make manipulator gripping spring smoothly, whole row's spring need to be risen, spring is sent in the tong of manipulator.Therefore, be necessary to research and develop a kind of lifting mechanism, can be by the carrying surface that is carrying spring vertical lifting abreast.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of carrying surface mechanism of vertical lift in parallel that makes.
For solving the problems of the technologies described above adopted technical scheme: a kind of lifting mechanism, comprise motor, by motor-driven output shaft and be installed in the eccentric shaft on output shaft, it is characterized in that: the both sides of described output shaft and eccentric shaft are respectively equipped with a lifting frame, described lifting frame comprises the first hold-down arm and the second hold-down arm, wherein the length of the first hold-down arm is the twice of the second hold-down arm, and point articulated in one end of the second hold-down arm and the first hold-down arm, the other end of the second hold-down arm and a bearing are hinged, the lower end of the first hold-down arm and the slide of line slideway auxiliary are hinged, if two connecting rods, one end of two connecting rods is hinged with slide described in respectively, and the other end is all hinged with eccentric shaft, the lifting frame of both sides is for placing in the same way, and the hinge-point of the hinge-point of the first hold-down arm and slide and the second hold-down arm and bearing is all established at grade, described slide is along the hinge-point of the first hold-down arm and slide and the linear slide between the second hold-down arm and the hinge-point of bearing.
The beneficial effect that adopts the present invention to bring: utilization of the present invention promotes the connecting rod crank motion of both sides around the eccentric shaft of output shaft rotation, drive the slide synchronous reciprocating of both sides to slide, drive the hinge-point of the first hold-down arm and slide to slide along the linear reciprocation between this hinge-point and the second hold-down arm and the hinge-point of bearing, make the upper end strong point synchronous vertical lifting in parallel of lifting frame first hold-down arm of both sides, be bearing in so also vertical lift abreast of the carrying surface that is carrying spring on the first hold-down arm of both sides.Make manipulator when capturing spring, can accomplish accurate control, guaranteed the stability of automatic producing device operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of lifting mechanism of the present invention.
The specific embodiment
As shown in Figure 1, a kind of lifting mechanism, the output shaft 2 that comprise motor 1, is driven by motor 1 and be installed in the eccentric shaft 3 on output shaft 2.The both sides of described output shaft 2 and eccentric shaft 3 are respectively equipped with a lifting frame, described lifting frame comprises the first hold-down arm 4 and the second hold-down arm 5, wherein the length of the first hold-down arm 4 is the twice of the second hold-down arm 5, and point articulated in one end of the second hold-down arm 5 and the first hold-down arm 4, the other end of the second hold-down arm 5 and a bearing 6 are hinged, and first lower end of hold-down arm 4 and the slide of line slideway auxiliary 7 are hinged.If one end of two connecting rod 8, two connecting rods 8 is hinged with a slide 7 respectively, the other end is all hinged with eccentric shaft 3.The lifting frame of both sides is for placing in the same way, and the first hold-down arm 4 is all established at grade with the hinge-point of bearing 6 with hinge-point and second hold-down arm 5 of slide 7.Described slide 7 is along the hinge-point of the first hold-down arm 4 and slide 7 and the linear slide between the second hold-down arm 5 and the hinge-point of bearing 6.The upper end strong point of lifting frame first hold-down arm 4 of both sides is in order to support the two ends of carrying surface.
Motor 1 driver output axle 2 rotates (in order to control better rotating speed, motor 1 can rotate by drop-gear box 9 driver output axles 2), 3 of eccentric shafts rotate around output shaft 2, eccentric shaft 3 promotes connecting rod 8 crank motions of both sides, and drive slide 7 synchronous reciprocatings of both sides to slide, drive the hinge-point of the first hold-down arm 4 and slide 7 to slide along the linear reciprocation between this hinge-point and the second hold-down arm 5 and the hinge-point of bearing 6 simultaneously.According to the operating characteristic of connecting rod mechanism, analyze the path of motion of lifting frame the first hold-down arm 4 and second hold-down arm 5 each end points, when the length of the first hold-down arm 4 is the twice of the second hold-down arm 5, and the non-pin jointed end of the second hold-down arm 5 is as fulcrum, will move along the mutually perpendicular straight line synchronous reciprocating between these two ends and the fulcrum of the second hold-down arm 5 respectively in the two ends of the first hold-down arm 4 so.Therefore, by the lifting frame of both sides be made as in the same way place and specification the same, and the first hold-down arm 4 is all established at grade with the hinge-point of bearing 6 with hinge-point and second hold-down arm 5 of slide 7, when slide 7 synchronous reciprocatings of both sides slide, the upper end strong point synchronous vertical lifting in parallel of lifting frame first hold-down arm 4 of both sides, is bearing in also vertical lift abreast of the carrying surface that is carrying spring on the first hold-down arm 4 of both sides so.
