1) adopt sprocket wheel, chain structure transmission system instantaneous velocity inhomogeneous, bumpy motion, abrasion of chain elongation back easily produces shake, jump tooth even fall serious mechanical breakdown such as chain, can bring unnecessary economic loss to production.
2) effective torque of chain transmission transmission is less, and the wearing and tearing of sprocket are more serious, because high vibration can produce bigger noise.
3) adopt motor as power source, higher relatively to environmental requirement.
Summary of the invention
The purpose of this utility model is to design a kind of workbench exchange mechanism, solves transmission system instantaneous velocity inequality and moves not plateau problem; Solve in the chain transmission process because violent jitter problem of transmission system that the sprocket wheel wearing and tearing cause and consequent big noise; And power source is to the environmental key-element problem of having relatively high expectations.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of workbench exchange mechanism, it comprises, frame, some workbench guiding that are used for support table that be arranged in parallel on it support; Intermediate base is installed in the middle of the frame upper surface, with the setting of workbench guiding supports parallel; Two line slideways are set in parallel on the intermediate base along the intermediate base length direction; Leading screw, its two ends are arranged on the intermediate base by bearing and diaxon bearing, and leading screw is positioned at the centre of two line slideways; Correspondence is provided with screw on the leading screw; Hydraulic motor, the bearing block by described leading screw one side and being bolted on the intermediate base, and be connected with described leading screw one end by shaft coupling; The workbench kerve, corresponding described two line slideways that be arranged in parallel in its bottom surface are provided with the rolling guide piece, and are slidedly arranged on this line slideway with this; Also fixedlying connected with the screw on the described leading screw in workbench kerve bottom surface between the rolling guide piece, and moves with screw; The workbench kerve is connected with workbench, and workbench is subjected to the pulling of workbench kerve and slides with respect to frame.
Further, described workbench guiding supports and is symmetricly set in described intermediate base both sides.
Be respectively equipped with some bearings in described two bearing blocks and cooperate, establish spacer between the bearing with leading screw.
Described two bearing block outboard ends are provided with end cap.
A described bearing block that is provided with hydraulic motor also is provided with the protective cover of protection hydraulic motor outward.
The inside of described intermediate base is provided with reinforcing rib structure.
The utility model has the advantages that:
1) from the transmission system type, the utility model thoroughly changes original sprocket wheel, chain transmission system, adopts the screw mandrel transmission system.The screw mandrel transmission system has than sprocket wheel, chain transmission system and operates steadily characteristics such as positioning accuracy height.
2) the utility model directly directly is not fixed on power source (hydraulic motor) on the frame (weldment), but is affixed on the frame after fixing by an intermediate base with a fixed structure again.
3) the utility model adopts hydraulic motor to replace motor as power source, and it has characteristics such as efficient height, noise is low, structure is compact more, volume is small and exquisite.
4) the integral layout advantages of simple of the utility model pallet changer, compact conformation is flexible.
5) associated components can be realized accurate, the steady location of workpiece in the work running, has effectively overcome the workpiece that occurs in the similar pallet changer and has located inaccurate problem.
6) satisfying under the prerequisite of job requirement, making full use of the lathe space, improving the utilization rate of effective working space, for the use of lathe has reduced cost.
