Abstract
The invention relates to a universal grinding device for a ball core of special a coal chemical ball valve for a drill lathe. The universal grinding device is characterized by comprising a taper shank (1) and a grinding plate (2) which are fixedly connected into a whole, wherein 4-8 grinding slots are uniformly distributed in the circumferential direction of the grinding plate (2), and a grinding sand bar is mounted in each grinding slot. The special universal grinding device further comprises a worktable (11) on which a rotating shaft (6) is mounted; one end of the rotating shaft (6) is in transmission connection with an external motor (5) through a transmission mechanism, and the other end is fixedly connected with a three-jaw (7); a tailstock (10) is further mounted on the worktable (11) beside the rotating shaft (6); a tip is mounted on the tailstock (10). The universal grinding device is used on Z525 and Z535 upright drills and can grind the ball core of the ball valve; the surface roughness is higher than 0.8, and the roundness reaches 0.01; the accuracy of machining dimension meets the technical requirement completely.
Description
Technical field
The present invention relates to a kind of drilling machine special coal ball valve for chemical industry ball core universal grinding device.
Background technology
Along with the control valve kind of using in coal chemical technology and quantity get more and more, require ball core sphere that higher hardness and anti-wear performance will be arranged.By adopting surfacing KF300C and the method that sprays WC-17Co on base material, ball wicking surface hardness can reach about HRC72 at present.But can not use cutter to carry out machining through the ball core after the surface treatment, and the sealing surface surface roughness is about 0.8, can not processes at general-purpose grinder.So, the bottleneck that is processed into machining of high rigidity ball core.And drilling machine is a kind of plant equipment of part being carried out hole class processing, in device update process in recent years, the part upright drill is left unused, on the other hand, along with the ball valve kind of using in coal chemical technology and quantity get more and more, the sphere processing of high rigidity ball core can't be finished production requirement, so, on upright drill, high rigidity ball core is carried out grinding and become exigence.
Summary of the invention
The purpose of this invention is to provide a kind of drilling machine special coal ball valve for chemical industry ball core universal grinding device, use behind this device and can carry out grinding to ball core sphere by enough drilling machines.
A kind of drilling machine special coal ball valve for chemical industry ball core universal grinding device, its special feature is: comprise being fixedly connected with taper shank and the abrasive disk that is integral, along circumferentially being evenly equipped with 4-8 grinding groove, the grinding emery stick is installed all in each grinding groove on this abrasive disk; Also comprise workbench, at this workbench rotating shaft is installed, one end of this rotating shaft is in transmission connection with external motor by transmission mechanism and its other end is fixedly connected with three-jaw, on the other workbench of this rotating shaft tailstock is installed also, is equipped with top at this tailstock.
Wherein on the other abrasive disk of each grinding groove, all be equipped with at least 2 and hold out against screw, thus the fixing emery stick that grinds.
Wherein taper shank is directly installed in the taper hole of drill press spindle.
Wherein at workbench support is installed, rotating shaft then is installed on this support.
Through probationary certificate, adopt universal grinding device of the present invention to use at Z525, Z535 upright drill, can carry out grinding to ball valve ball core, surface roughness reaches more than 0.8, and circularity reaches 0.01, and accurate to dimension satisfies specification requirement fully.
Description of drawings
Accompanying drawing 1 is the structural representation of abrasive disk 2 parts among the present invention;
Accompanying drawing 2 is use view of the present invention.
The specific embodiment
As shown in Figure 1, 2, the present invention is a kind of drilling machine special coal ball valve for chemical industry ball core universal grinding device, comprise being fixedly connected with taper shank 1 and the abrasive disk 2 that is integral, on this abrasive disk 2, along circumferentially being evenly equipped with 4-8 grinding groove, in each grinding groove, all being equipped with and grinding emery stick 3.Also comprise workbench 11, at this workbench 11 rotating shaft 6 is installed.At workbench 8 support is installed in addition, this rotating shaft 3 then is installed on this support, and rotating shaft 3 comprises housing, axle, bearing, and the one end can be installed belt pulley, and the other end can be installed three-jaw.Specifically an end of this rotating shaft 6 is by transmission mechanism, for example is with the kind of drive to be in transmission connection with external motor 5 and its other end is fixedly connected with three-jaw 7, on the workbench 11 by this rotating shaft 6 tailstock 10 is installed also, is equipped with top at this tailstock 10.
Wherein on the other abrasive disk 2 of each grinding groove, all be equipped with at least 2 and hold out against screw 4, thus the fixing emery stick 3 that grinds.Grinding emery stick 3 matrixes is that the cross section is the 20X20mm aluminum alloy bar, and grinding part is diamond dust.Taper shank one end is connected with abrasive disk with the 4XM10 bolt, and the taper shank other end can be directly installed in the drill press spindle taper hole.
Using method of the present invention and operation principle are:
As shown in Figure 2, ball core 8 to be processed is installed on the workbench 11 of drilling machine by expander mandrel 9, abrasive disk 2 parts of the present invention are installed on the drill press spindle, ball core 8 to be processed moves in a circle under the drive of external motor 5, simultaneous grinding dish 2 is High Rotation Speed under the drive of drill press spindle, and ball core 8 spheres to be processed are carried out grinding.
Grinding head is connected with taper shank 1 part, and taper shank 1 can be directly installed on the drill press spindle, on abrasive disk 2, is equipped with 4-8 and grinds emery stick 3, and drill press spindle drives abrasive disk 2 High Rotation Speeds, realizes the grinding to ball core 8 to be processed.
