Abstract
The invention relates to a left-and-right screw device in automatic production equipment. The left-and-right screw device capable of adjusting the lead screw nuts comprises lead screws, two bearing seats, two movable seats and two lead screw nuts, wherein the two lead screw nuts are fixedly arranged on the movable seats, the two bearing seats are arranged on the lead screws respectively through the lead screw nuts, and at least one lead screw nut is provided with an adjusting device. The adjusting device is formed by an adjusting washer, adjusting screws, locking nuts and fixing screws. The adjusting washer is arranged between the lead screw nuts and the movable seats, a plurality of adjusting screws and a plurality of fixing screws are arranged and are sequentially distributed on the lead screw nuts at intervals, the fixing screws penetrate through the adjusting washer to fix the lead screw nuts and the adjusting washer on the movable seats, the inner ends of the adjusting screws abut against an outer wall of the adjusting washer, and the outer ends of the adjusting screws are positioned through the locking nuts. The left-and-right screw device has the advantages of being simple in structure, continuous and rapid to adjust and high in reliability and eliminating difference of left-and-right thread intervals easily.
Description
Technical field
The present invention relates to the left-and-right spiral device in automated production equipment.
Background technique
In existing automatic production, power screw often can use a kind of left-and-right spiral mechanism (as shown in Figure 1), and two ends screw thread is respectively left and right hand thread, rotated make two ends object equidistantly draw close to center or be separated by screw mandrel.Because the starting point of screw thread is different, consistent in order to ensure decentre distance, the mode of auger shell hole (Fig. 2) or milling elongated slot (Fig. 3) is joined in general employing: Fig. 2 structure is simple, but install trouble, higher to assembly crewman's competency profiling, when feed screw nut is worn and torn and is changed, need again distribution or pad of jumping a queue, pad of jumping a queue adjustment is discontinuous, and gap removes difficulties, the used time is longer; Fig. 3 utilizes frictional force driving torque, and reliability is poor, when especially driving torque is larger, and easy relative sliding.
Summary of the invention
In order to solve above-mentioned technical problem, the object of this invention is to provide the left-and-right spiral device of a kind of adjustable feed screw nut, it is simple that this device has structure, is easy to eliminate left and right thread pitch difference, and adjustment is continuous, quick, the feature that reliability is high.
In order to realize above-mentioned object, the utility model have employed following technological scheme:
The left-and-right spiral device of a kind of adjustable feed screw nut, this device comprises screw mandrel, two bearing supports, two Mobile bases and two feed screw nuts, two ends of screw mandrel are separately positioned on described bearing support, two feed screw nuts are fixedly installed on Mobile base, two bearing supports are arranged on screw mandrel respectively by feed screw nut, and at least one feed screw nut is provided with regulating device, described regulating device is by adjusting packing ring, adjustment screw, locking nut and set screw are formed, adjustment packing ring is arranged between feed screw nut and Mobile base, adjustment screw and set screw have multiple respectively, spaced apartly successively be arranged on feed screw nut, feed screw nut and adjustment packing ring are fixed on Mobile base through adjustment packing ring by set screw, the inner of adjustment screw offsets with the outer wall of adjustment packing ring, outer end is located by locking nut.
As further improvement, described adjustment screw and set screw have 8 respectively.
The present invention, owing to have employed above-mentioned technological scheme, provides the left-and-right spiral device of a kind of adjustable feed screw nut, and it is simple that this device has structure, is easy to eliminate left and right thread pitch difference, and adjustment is continuous, quick, the feature that reliability is high.
