Abstract
The invention discloses a method for improving the grinding precision of a main shaft. The method comprises the following steps of passing a process bulkhead through a screw hole at the head of the main shaft; fixing the process bulkhead on the main shaft by use of a hexagonal nut, wherein the conical surface of the process bulkhead is tightly contacted with the orifice chamfer of the screw hole at the head of the main shaft, and simultaneously the end face of the process bulkhead is slightly higher than that of the main shaft; and then grinding the end face of the main shaft, wherein interrupted grinding is replaced by continuous grinding. The invention further discloses a process bulkhead used in the method. The process bulkhead comprises a column body and a base connected with the column body, wherein the front end of the column body is provided with a thread; the side surface of the base is provided with a conical surface; and the bottom surface of the base is provided with a groove. By utilizing the method disclosed by the invention, the grinding precision of the main shaft is greatly improved, and the precision is improved by more than one time; the grinding is stable; the abrasion of a grinding wheel is less; the regrinding frequency of the grinding wheel is effectively reduced; the auxiliary time is reduced, and the grinding efficiency is improved; and the process bulkhead is simple in structure and is convenient and rapid to assemble and disassemble.
Description
Technical field
The present invention relates to a kind of method for grinding, the technology that specifically improves the method for main shaft grinding accuracy and be used for this method silently.
Background technology
In machine industry, numerically controlled lathe is widely used, and the precision of Digit Control Machine Tool processing parts improves constantly; The critical component of lathe; The end face accuracy class of spindle nose is increasingly high, because the main shaft end face has 12 screws, emery wheel is when the grinding spindle end face; There is the intermittent grinding phenomenon, thereby influences the grinding accuracy of main shaft end face.
Summary of the invention
The objective of the invention is the deficiency that exists to prior art, a kind of technology that improves the grinding process method of main shaft end face grinding accuracy and be used for this method is provided silently.
For realizing the foregoing invention purpose, the technical scheme that the present invention adopts is a kind of method that improves the main shaft grinding accuracy, may further comprise the steps:
(1) at first technology is silently run through the screwed hole of spindle nose;
(2) with silently being fixed on technology on the main shaft in the hex nut screw-in screw thread;
(3) conical surface that silently is provided with of technology closely contacts with the aperture chamfering of spindle nose screwed hole, simultaneously technology silently end face a little more than the main shaft end face;
(4) carry out the main shaft cross grinding then, intermittent grinding is become continuous grinding.
A kind of technology that is used to improve main shaft grinding accuracy method silently comprises cylinder and the base that joins with cylinder, and the front end of said cylinder is provided with screw thread, and the side of said base is the conical surface, and the bottom surface of base also is provided with groove.
Beneficial effect: 1, do not have technology grinding process method silently before comparing, the main shaft grinding accuracy increases substantially, and precision improvement is more than one times; 2, grinding is more steady, and abrasion of grinding wheel is little, effectively reduces emery wheel reconditioning number of times, reduces non-cutting time, has improved grinding efficiency; 3, technology is silently simple in structure, easy to loading and unloading, quick.
Description of drawings
Fig. 1 is technology structural representation silently among the present invention;
Fig. 2 is an installation diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, present embodiment is being to implement under the prerequisite with technical scheme of the present invention, should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention.
Like Fig. 1 and shown in Figure 2, a kind of technology that is used to improve main shaft grinding accuracy method silently comprises cylinder 1 and the base 2 that joins with cylinder, and wherein the front end of cylinder 1 is provided with screw thread 3, and the side of base 2 is the conical surface, and the bottom surface of base 2 also is provided with groove 4, is convenient to install.
Method for grinding is following:
(1) at first technology is silently run through the screwed hole of spindle nose;
(2) with silently being fixed on technology on the main shaft in the hex nut screw-in screw thread;
(3) conical surface that silently is provided with of technology closely contacts with the aperture chamfering of spindle nose screwed hole, simultaneously technology silently end face a little more than the main shaft end face;
(4) carry out the main shaft cross grinding then, intermittent grinding is become continuous grinding, thereby guarantee the end face precision of spindle nose.
Claims (2)
1. method that improves the main shaft grinding accuracy is characterized in that may further comprise the steps:
(1) at first technology is silently run through the screwed hole of spindle nose;
(2) with silently being fixed on technology on the main shaft in the hex nut screw-in screw thread;
(3) conical surface that silently is provided with of technology closely contacts with the aperture chamfering of spindle nose screwed hole, simultaneously technology silently end face a little more than the main shaft end face;
(4) carry out the main shaft cross grinding then, intermittent grinding is become continuous grinding.
2. a technology that is used to improve main shaft grinding accuracy method silently; It is characterized in that: comprise cylinder (1) and the base (2) that joins with cylinder (1); The front end of said cylinder (1) is provided with screw thread (3); The side of said base (2) is the conical surface, and the bottom surface of base (2) also is provided with groove (4).
