Description
Technical field
The present invention relates to a kind of process unit of valve flat seal face grinding, enable in particular to be applied to different type valve
Door, and different dimensions valve sealing face grinding.
Background technology
Current valve flat seal face grinding majority is hand lapping, and some simple hand grinding tools, Ke Yiman
Sufficient valve use requirement.But the efficiency of grinding is low, the plane of different quality can be ground in the different people of experience, and qualification rate can not
Ensure, cause each valve seal face thickness to differ than larger.Hand lapping and simple milling tool can not be controlled accurately
Grinding pressure processed, abrasive disk assembly diameter dimension, grinding quality can not ensure.
The content of the invention
In order to overcome existing milling tool to adjust grinding pressure, the deficiency of abrasive disk assembly diameter dimension, sheet
Invention provides a kind of grinding tool, and the frock can not only adjust pressure size during sealing surface grinding, and can easily adjust
Abrasive disk assembly diameter acts, and pressure and the eccentric diameter data value of abrasive disk assembly under accurate recording.
The technical solution adopted in the present invention is that main casing is installed on machine tool chief axis hole, using machine tool chief axis rotation come
Drive whole grinding tool rotary motion.By controlling the decrement of spring, the active force of spring is applied on grinding work-piece,
Realize control of the abrasive disk assembly to the grinding normal force of workpiece.Using eccentric shaft and the double eccentric structures of eccentric bushing, realize
The regulation of abrasive disk assembly offset.The circular conical surface design of active disk, realizes that abrasive disk assembly exists in abrasive disk assembly
In process of lapping have universal adjustment function, by change spring decrement and regulation abrasive disk assembly offset or
Other sizes grinding head is changed, goes for being ground a variety of grinding work-pieces.
The beneficial effects of the invention are as follows, can be while workpiece be ground, accurately record grinding pressure value and grinding
Disk diameter dimension data, convenient next time is ground using same data to identical jobs.Optimal effectiveness is most ground to reach, versatility
By force, milling time is saved, grinding efficiency and quality is improved.

Embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
Such as Fig. 1, shown in 2, a kind of valve sealing face plane lapping frock, main casing (1) and eccentric bushing (3) coordinate installation,
Main casing (1) upper end conical section is connected with machine tool chief axis (10) cone match, shape after eccentric bushing (3) coordinates with main casing (1)
Into chamber spring (2) is installed, the effect of spring (2) is to provide appropriate pressure to being ground workpiece (8).By lock-screw
(4) tighten, the sliding stroke between control eccentric bushing (3) and main casing (1).Eccentric bushing (3) is entered with main casing (1) relative position
Row is spacing, and eccentric bushing (3) outer surface carries pressure scale (17) (as shown in Figure 1), and eccentric shaft (9) is matched somebody with somebody with eccentric bushing (3) conical surface
Connection is closed, eccentric shaft (9) carries offset scale (18) (as shown in Figure 1), and offset is by adjusting trip bolt (19) come complete
Into abrasive disk assembly (21) is an assembly parts, is connected with eccentric shaft (9) by screw thread, abrasive disk assembly (21)
Pass through, box (11) coordinates with active disk (12) to be installed, and active disk (12) has beveled tip structure (as shown in Figure 2), living
Network disk (12) coordinates with drag ring (13) to be installed, and active disk (12) is fixed by screw (16), prevents box (11) and active disk
(12) rotary motion each other, end cap (14) and box (11) are fixed by screw 2 (16).
The technical characterstic of the present invention is that the decrement of spring (2) can be adjusted in workpiece process of lapping, to provide difference
The normal force perpendicular to abradant surface, and pressure scale can be recorded.Eccentric bushing (3) is provided with spring travel elongated hole sideways,
Decrement to control spring.Eccentric bushing (3) and eccentric shaft (9) are eccentric structures, thus it is possible to vary the size of offset,
To meet various sizes of workpiece grinding demand.And the scale value of offset can be recorded.For larger workpiece, it can pass through
The mode of bigger abrasive disk assembly (21) is changed to meet size requirement.Eccentric shaft (9) is connected with eccentric bushing (3), matches somebody with somebody
Conjunction face is the conical surface, and the conical surface has the effect of automatic centering.Removal hole is designed with eccentric bushing (3) and eccentric shaft (9) matching part
(5) and dismounting groove (6) (as shown in Figure 2), it is convenient due to eccentric bushing (3) with eccentric shaft (9) because the effect of power is difficult to tear open
The problem of unloading.Active disk (12) is conical structure, cooperatively forms universal structure with box (11), drag ring (13) is in eccentric shaft
(9) rotated under drive, active disk (12) can not be rotated with box (11) by screw 2 (16) fastening.Active disk (12) and box
Frictional force between sub (11) drives whole abrasive disk assembly to rotate, so as to realize the function of grinding.
Frock assembly is installed in machine tool chief axis hole, empirically value adjustment amount of spring compression and offset, lead to
The rotation for crossing machine tool chief axis drives whole frock assembly to rotate, and realizes the process ground to workpiece.
