Abstract
The invention relates to a high-precision grinding machine mainly comprising a machine body, a worktable, a grinding head main shaft, a grinding head and a main shaft motor, wherein the grinding head main shaft is arranged on the machine body above the worktable, and the grinding head is arranged at the front end part of the grinding head main shaft. The high-precision grinding machine is characterized in that the grinding head main shaft is a hydrostatic bearing main shaft; an oil inlet and an oil return opening on the hydrostatic bearing main shaft are respectively connected with an oil outlet and an oil return opening of a hydraulic station; and the machine body above the worktable is provided with a grating ruler of a high-precision digital display screen. The invention has scientific and reasonable structural design so as to meet the processing requirements of parts with higher roughness and assembly precision and has convenient and simple operation and high efficiency, thereby being a grinding machine with higher innovativeness and high precision.
Description
Technical field
The invention belongs to machine tool field, particularly a kind of high-precision grinder.
Background technology
At present, the part that has higher assembly precision in processing, for example, when presser feet handle shown in Fig. 1 and presser feet base plate, because presser feet handle size L adopts gap fiting mode to be installed on the size L1 of presser feet base plate, the gap value of the two requires very little, is 0.005mm, existing grinding machine can't satisfy the tolerance of the two, and the roughness that processes can not meet the demands.At present, only can pass through the L1 of each presser feet base plate part of actual measurement, according to the L size of measurement result match grinding pressure foot, be the mode of 0.005mm to guarantee gap value, reduces the roughness requirement simultaneously.There is following drawback in it: working (machining) efficiency is low, increases processing cost; And the part of each group part and other group does not have interchangeability.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of high-precision grinder is provided, it can accurately control the grinding size, improves the processing roughness, guarantees the workpiece tolerance.
The present invention solves its technical problem and takes following technical scheme to realize:
A kind of high-precision grinder, it mainly is made of bed body, workbench, grinding spindle, bistrique, spindle motor, grinding spindle is installed on the bed body of workbench top, bistrique is installed on the leading section of grinding spindle, it is characterized in that: described grinding spindle is the hydrostatic bearing main shaft, and oil-in on this hydrostatic bearing main shaft and oil return opening are connected with the oil-out and the oil return opening of a Hydraulic Station respectively; Bed body inside in the workbench correspondence is equipped with the grating chi, and the digital display screen of grating chi is installed on the bed body above the workbench.
Advantage of the present invention and good effect are:
1. the present invention installs the hydrostatic bearing main shaft on the bed body of economical grinding machine, and the hydrostatic bearing speed of mainshaft can reach 15000 rev/mins, thereby improves the roughness of part processing face greatly.
2. the present invention installs grating chi and digital display screen on the bed body of economical grinding machine, thereby can realize precisely controlling the feeding of workbench, feed accuracy has reached μ m, makes the groove of machining high-precision become possibility, satisfies the tolerance of part processing, and has high stability, through practice, the processing parts tolerance is controlled in the 0.005mm, and qualification rate can reach 100%, and all parts have interchangeability, and assembling brings very big facility to part.
3. scientific structure design of the present invention is reasonable, satisfies the process requirements of higher roughness and assembly precision part, and easy and simple to handle, and the efficient height is a kind of high-precision grinder that has than high innovation character.

Fig. 2 is two a structural representation of part to be processed;
Fig. 3 is the structural representation of high-precision grinder of the present invention;
Fig. 4 is the left view of Fig. 2.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing, by specific embodiment.
A kind of high-precision grinder, it mainly is made of bed body 3, workbench 4, grinding spindle, bistrique, spindle motor 14, and grinding spindle is installed on the bed body of workbench top, and bistrique is installed on the leading section of grinding spindle, and spindle motor drives grinding spindle and rotates.Wherein, grinding spindle is a hydrostatic bearing main shaft 10, and bistrique 11 is installed on this hydrostatic bearing main shaft.Oil-in 9 on this hydrostatic bearing main shaft and oil return opening 13 are connected with the oil-out 6 and the oil return opening 7 of a Hydraulic Station respectively.The hydrostatic bearing speed of mainshaft can reach 15000 rev/mins, thereby improves the roughness of part processing face greatly.Frock 12 is installed on workbench.At the high-precision grating chi 15 of the inner installation of the lathe of workbench correspondence, the digital display screen 5 of grating chi is installed on the bed body above the workbench, the displacement of workbench can be shown in real time, thereby the feeding of workbench can be realized precisely controlling.
The operating process of this grinding machine is:
1. oil-out and the oil return opening with Hydraulic Station links to each other with the oil-in and the oil return opening of main shaft respectively, starts Hydraulic Station, adjusts oil pressure to 1.7MPa～1.8MPa, and with the light rotating spindle of have gentle hands, without any the friction sensation, this moment, main shaft was in the static pressure state.
2. start spindle motor, running half an hour, observing has no abnormally, cuts off spindle motor then, this moment main shaft at the supporting state of static pressure oil, promptly the center of main shaft overlaps fully with the center of main shaft bearing shell, no anyly directly contact between main shaft and the bearing shell.
3. workpiece is placed on the frock, starts spindle motor, make spindle operation, the size L1 of grinding part 2, the size L of grinding part 1, grinding process is the same with general-purpose grinder, no longer describes in detail.
Although disclose embodiments of the invention and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the present invention and claims, various replacements, variation and modification all are possible, therefore, scope of the present invention is not limited to embodiment and the disclosed content of accompanying drawing.
