The utility model belongs to the technical field of lathes, and particularly relates to an automatic clamping machine tool main shaft box with a built-in rotating shaft. According to the main shaft box, the shaft box comprises a main shaft and bearings inside, and is characterized in that the shaft box and the bearings are connected and adjacent to each other; the bearings and the main shaft are connected and adjacent; the bearings are fixed at two ends between the shaft box and the main shaft by bearing pressure plates through fastening screws; the main shaft and pistons are connected and adjacent to each other; groove holes are formed in connecting faces of the pistons and sealing sleeve; springs are placed in the groove holes of the pistons; the sealing sleeve is arranged at one ends, adjacent to a processing workpiece, of the pistons for preventing the outleakage of hydraulic oil; two clamping sleeves, penetrating the workpiece, are positioned between the two pistons; belt pulley is fixed between the bearings on the main shaft; the belt pulley is used for delivering motive power to allow the main shaft to rotate; and a hydraulic oil junction joint is connected with a hydraulic oil oil-guiding hole in the main shaft for providing hydraulic motive power. The main shaft box realizes the advantages of high processing accuracy, high production efficiency, high automation degree, and low cost, and has convenience in using.
Description
Technical field
The utility model belongs to the machine tool technology field, is specifically related to the built-in automatic clamping lathe headstock of a kind of gyroaxis, when being used for the machine tooling parts, workpiece is carried out automatic clamping.
Background technology
In the process of axle sleeve class part, need to clamp earlier an end of processed parts usually, it is processed, the other end is processed in tune then, finish with two lathes, during owing to two machine toolings, form two pivots, therefore, cause the concentricity at workpiece two ends bad, machining accuracy is low, and production efficiency is low, the energy consumption height, the cost height.
Summary of the invention
The purpose of this utility model is exactly at the problems referred to above, and a kind of machining accuracy height is provided, production efficiency height, the lathe headstock of the built-in automatic clamping of gyroaxis that automaticity is high.
The technical solution of the utility model is: the built-in automatic clamping lathe headstock of a kind of gyroaxis, comprise main shaft and bearing in the axle box, it is characterized in that: said axle box and bearing adjacency, said bearing and main shaft adjacency, bearing plate by hold-down screw with the two ends of bearing fixing between axle box and main shaft, main shaft and piston adjacency, be shaped on slotted eye on the face that piston and sealing shroud join, spring places the slotted eye of piston, piston is provided with sealing shroud in abutting connection with an end of workpiece to be machined, be used for preventing hydraulic fluid leak, two gripping sleeves pass workpiece between two pistons, and belt pulley is fixedly arranged between the main shaft upper bearing (metal), and belt pulley is used for transferring power rotates main shaft, the hydraulic oil jointing is connected with hydraulic oil oil guiding hole on the main shaft, is used for providing hydraulic power.
Further technical scheme of the present utility model is: be provided with sealing ring between main shaft and the piston, be provided with sealing ring between piston and the sealing shroud.
The technical solution of the utility model has realized following beneficial effect:
1. precision height.Can a clamping, the two sides can process simultaneously, reduces alignment error, the precision height;
2. production efficiency height.Adopt built-in automatic loose clamp device, clamping speed is fast, and the two sides processes simultaneously, the production efficiency height;
3. automaticity height: use hydraulic power to clamp and unclamp workpiece, should realize automation;
4. cost is low.Simple in structure, handling ease, production cost is low;
4. easy to use.Adopt conventional mounting means, compact conformation, simple installation is easy to promote.
