Abstract
The utility model relates to a cooling structure used for a grinder. A workpice is cooled by cooled water through a cooling device fixed in the main shaft of the workpiece; the cooling device is fixed; and the main shaft of the workpiece rotates along the cooling device. The detail structure is as follows: a through hole is arranged inside the main shaft of the workpiece; a mandrel, a bearing, a current shutting block and an outflow tube are arranged in the through hole; the outer ring of the bearing is in interference fit with the main shaft of the workpiece; the inner ring of the bearing is in interference fit with the mandrel; one end of the mandrel is clamped in a fixed board; and the other end of the mandrel is connected with the outflow tube by the current shutting block. The utility model has the advantages that: 1, both the angle and the length of the outflow tube of the cooled water are adjustable; the direction, pressure and flux of the cooled water at the grinding part can be optimized so as to achieve the best effect of cooling and chip removal; 2, the structure is compact and the airtight is good and the mounting and dismounting are convenient; 3, a rotary joint is avoided, thus saving the cost; 4, a larger space is arranged in the main shaft for setting a detection device.
Description
Technical field
The utility model relates to a kind of cooling structure, is a kind of cooling structure that is used for grinding machine specifically.
Background technology
Tradition grinding machine cooling structure all replaces water pipe at the work spindle center drilling, and mandrel is connected by gas thread with the work spindle tail end, and the outer ring sleeve is fixed, and working method is the mandrel rotation, and the outer ring is motionless.There is following problem in this mechanism: the one, and angle of water can't be regulated, and cooling effect does not reach optimum; The 2nd, to hole shape in the main shaft and be sealed with certain requirement, increased the difficulty of processing of spindle unit; The 3rd, swivel joint need be set, increased cost; The 4th, under the modern times, processing was to the more and more higher situation of the requirement of precision, often need the device that machining accuracy, material temperature etc. are detected in real time is set, and traditional type of cooling can't be provided with checkout gear because the space is narrow and small.
The utility model content
In order to solve the problems of the technologies described above, the utility model is broken through traditional outer ring and is fixed, the working method of inner ring rotation, thoroughly carry out technological improvement from structure, a kind of grinder cooling method and structure are provided, concrete grammar is: cooling water is by being fixed on the cooling device cooling workpiece in the work spindle, and described cooling device is fixed in fixed head, and described work spindle rotates around cooling device.
The concrete structure of realizing said method is:
A kind of grinding machine cooling structure comprises work spindle, fixed head, in the described work spindle through hole is arranged; Mandrel, bearing, branching block, outlet pipe are arranged in the described through hole; Described bearing outer ring and work spindle interference fit, bearing inner race and mandrel interference fit; One end of described mandrel is stuck in the fixed head, and the mandrel other end connects outlet pipe by branching block.
For reaching sealing effectiveness, described cooling body also comprises axle sleeve, left and right sides bearing cap, felt collar; Described axle sleeve outer ring is tightened in work spindle by screw thread, axle sleeve inner ring and bearing outer ring interference fit; Described left and right bearing cap is fixed in the axle sleeve two ends; Described felt collar is arranged in the left and right bearing cap.
For preventing that cooling water is penetrated into outside the work spindle, described axle sleeve root is provided with sealing ring.
For reaching better cooling effect, described outlet pipe angle and adjustable length, described outlet pipe is more than 2 or 2.
The utility model has the advantages that: 1. cooling water outlet pipe angle and length all can be adjusted, and can optimize direction, pressure and the flow of grinding position cooling water, to reach the optimum efficiency of cooling and chip removal; 2. this mechanism structure compactness, good airproof performance, easy installation and removal; 3. need not to be provided with swivel joint, reduced cost; 4. in main shaft, there is bigger space that checkout gear is set.
