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 sides screw in the automated production equipment.
Background technique
In existing automatic production, a kind of left and right sides screw mechanism (as shown in Figure 1) is often used in the power screw meeting, and the two ends screw thread is respectively the left and right screw thread that revolves, and rotates through screw mandrel to make two ends object equidistance draw close or separate to the center.Because the starting point of screw thread is different; In order to guarantee decentre apart from unanimity, the general mode of joining auger shell hole (Fig. 2) or milling elongated slot (Fig. 3) that adopts: Fig. 2 is simple in structure, but trouble, higher to assembly crewman's competency profiling is installed; The feed screw nut is worn and torn when changing; Need join the hole again or the pad of jumping a queue, the pad of jumping a queue adjustment is discontinuous, and the gap removes difficulties, the time spent is longer; Fig. 3 utilizes the frictional force driving torque, and reliability is relatively poor, under the situation that especially driving torque is bigger, and easy slide relative.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of feed screw nut's of adjustment left and right sides screw, this device has simple in structure, is easy to eliminate left and right sides thread pitch difference, and adjustment is continuous, quick, high reliability features.
In order to realize above-mentioned purpose, the technological scheme below the utility model has adopted:
A kind of left and right sides screw of adjusting the feed screw nut, this device comprise screw mandrel, two bearing supports, two mobile seats and two feed screw nuts, and two ends of screw mandrel are separately positioned on the described bearing support; Two feed screw nuts are fixedly installed on and move on the seat; Two bearing supports are arranged on the screw mandrel through the feed screw nut respectively, and at least one feed screw nut is provided with regulating device, and described regulating device is made up of adjustment packing ring, adjustment screw, locking nut and set screw; The adjustment packing ring is arranged on the feed screw nut and moves between the seat; Adjustment screw and set screw have a plurality of respectively, spaced apart successively being arranged on the feed screw nut, and set screw passes the adjustment packing ring feed screw nut is fixed on the mobile seat with the adjustment packing ring; The inner of adjustment screw offsets with the outer wall of adjustment packing ring, and the outer end is through the locking nut location.
As further improvement, described adjustment screw and set screw have 8 respectively.
The present invention provides a kind of feed screw nut's of adjustment left and right sides screw owing to adopted above-mentioned technological scheme, and this device has simple in structure, is easy to eliminate left and right sides thread pitch difference, and adjustment is continuous, quick, high reliability features.
