Abstract

The utility model relates to an adjustable pneumatic-electric valve grinder, which is composed of a grinding head 1, a grinding rod 2, a fixed tray 3, a bearing 4, a through hole 5, a fixed frame 6, etc. Existing sealing surfaces of valves is grinded by manual tools, so the quality is hard to be assured, the utility model can replace manual operation and has the functions of automatic length regulating and automatic aligning, and the utility model has the advantages of good grinding quality and high efficiency.

Description

Adjustable pneumoelectric movable valve grinder

The utility model is a kind of mechanical device, promptly a kind of adjustable pneumoelectric movable valve grinder.

Valve internal all has an end face that is used to seal mostly, and its fineness requires than higher, thereby when making or safeguarding, need grind.At present, the grinding of valve internal end face adopts manual method to carry out, and holds lapping apparatus by staff, turns rotation and grinds.What also have uses electric tool, but also by manual manipulation.This main by people's the experience and the processing method of sensation, the precision of grinding and angle are difficult to guarantee.

The purpose of this utility model is that a kind of energy of development replaces manual operations, the grinder that machining accuracy and angle can both meet the requirements.

Technical scheme: this grinder also has a grinding head that is contained on the milling bar, and different is, said milling bar is contained on the fixed mount, and milling bar is equipped with in the middle of fixed mount the through hole of bearing and passes through, and the upper end links to each other with engine by drive disk assembly.The fixed disk that is located by connecting with valve is arranged below the fixed mount.

Said milling bar is to be pegged graft by slotted hole and pin by last milling bar and following milling bar, has spring to support between the two, forms a kind of being slidingly connected of can stretching vertically.

The grinder that adopts such scheme to make can replace manual operations fully, and it is long to have an automatic accent, the function of automatic capturing, and Grinding Quality is good, the efficient height, thus solved prior art problems.

Introduce two kinds of embodiment below in conjunction with accompanying drawing:

Fig. 1 is the front view of present embodiment, and Fig. 2 is that it uses schematic diagram.

Fig. 3 is the front view of second kind of embodiment, and Fig. 4 is that it uses schematic diagram.

As seen from Figure 1: grinding head 1, milling bar 2, fixed disk 3, bearing 4, through hole 5, fixed mount 6.

As seen from Figure 2, milling bar joint 7, split pin 8, single thrust bearing 9, last milling bar 10, inner spring 11, slotted hole 12, pin 13, outer spring 14, following milling bar 15, end face 16, valve body 17.

As shown in the figure, the grinding head 1 of this grinder is contained on the milling bar 2, and milling bar 2 is to be formed by connecting by last milling bar 9, following milling bar 15.Following milling bar is inserted in milling bar the inside, on the following milling bar slotted hole 11 is arranged, and circular hole is arranged on the last milling bar, become scalable rod member by pin 12 cross-under.By inside and outside two springs between two sections milling bars to the two ends roof pressure, like this, can guarantee the pressure of grinding head to face machined flat, but automatic capturing again, automatically regulate length, milling bar stretches out from the through hole 5 of fixed mount 6, is joined by split pin 8 and milling bar joint 7, joins with pneumatic or electronic engine again.Fixed mount 6 can be made up of last dish and lower wall, between fuse by bolt, like this, can weight reduction, guarantee the length of through hole, make the milling bar stable rotation, the fixed mount lower wall is that fixed disk 3 can link to each other with valve body.

Second kind of embodiment that Fig. 3 and 4 is introduced, its principle is identical with first kind, and just fixed disk is different with the type of attachment of valve body, the end plane angle difference of grinding.Preceding a kind of fixed disk is to be connected mutually with valve by hook, and the face of processing is the inclined-plane, and this fixed disk is to be connected with valve body with screw by bolt, and the end face that is ground is the plane.

After installing as Fig. 2 or method shown in Figure 4, start engine, can carry out grinding operation, its Grinding Quality has been compared significant raising with efficient with manual operations.

Claims

1, a kind of adjustable pneumoelectric movable valve grinder, a grinding head (1) that is contained on the milling bar (2) is also arranged, it is characterized in that: said milling bar (2) is contained on the fixed mount (6), milling bar (2) is equipped with in the middle of the fixed mount (6) the through hole (5) of bearing (4) and passes through, the upper end with link to each other with engine by drive disk assembly, the fixed disk (3) that is located by connecting with valve is arranged below the fixed mount.

2, adjustable pneumoelectric movable valve grinder according to claim 1, it is characterized in that: said milling bar (2) is to be pegged graft by slotted hole (12) and pin (13) by last milling bar (10) and following milling bar (15), there is spring to support between the two, forms a kind of being slidingly connected of can stretching vertically.
