Abstract
The invention relates to a grinder cooling method and a grinder cooling structure. Cooling water cools a workpiece through a cooling device fixed in a main shaft of the workpiece; the cooling device is fixed; and the main shaft of the workpiece rotates around the cooling device. The structure is characterized in that: the main shaft of the workpiece is provided with through holes; a mandrel, a bearing, a diverter block and a water outlet pipe are arranged in the through holes; an outer ring of the bearing is in clearance fit with the main shaft of the workpiece, and an inner ring of the bearing is in clearance fit with the mandrel; and one end of the mandrel is clamped in a fixing plate, while the other end is connected with the water outlet pipe through the diverter block. The method andthe structure have the advantages that: 1, the angle and length of the cooling water outlet pipe can be adjusted to optimize the direction, pressure and flow of the cooling water on a ground part so as to achieve the optimal effects of cooling and removing chips; 2, the mechanism has compact structure, good leak tightness, and convenient assembly and disassembly; 3, a rotary joint is not requiredto be arranged so as to reduce cost; and 4, the inside of the main shaft is provided with a large space for accommodating a detection device.
Description
Technical field
The present invention relates to a kind of cooling means and structure, is a kind of cooling means and 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.
Summary of the invention
In order to solve the problems of the technologies described above, the present invention breaks through traditional outer ring and fixes, 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.
Advantage of the present invention is: 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.
