Abstract

The utility model provides an abrading machine for a valve clack. An abrading disk is supported by a supporting base, and a spindle is fixed by a bottom bearing seat and a top bearing seat which are respectively connected with the supporting base and the abrading disk. A spindle drive device is arranged between the top and the bottom bearing seats. The upper part of the spindle is provided with a cross arm. The cross arm is connected with a bracket through a small axle and a small axle bed. A fluted disk with holes in which a valve clacks in arranged is connected with the bracket and is meshed with a stationary gear. The abrading machine for a valve clack has simple fabrication. The abrading mode of the valve clacks is that rotation overlaps with revolution. The abrasive valve clack has high quality. The machine has fast abrading rate and can abrade many valve clacks once. The utility model is appropriate for the valve clacks abrasion of valve valves.

Description

Finishing machine for valve clack

The utility model relates to a kind of machine that grinds the flap of valve.

Process the flap of valve in the past, what have grinds by manual, the use large planetary grinder that has, and the use that also has vibrations grinder, its purpose all is the machining accuracy that guarantees sealing surface by grinding.Weak point is a processing machine cost height, and grinding efficiency is low, and the scope of application is limited etc.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of multiple valve that is suitable for grinding is provided, and the machine cost is low, Grinding Quality height, the flap grinder that operating efficiency is fast.

The purpose of this utility model can reach by following measure: abrasive disk 9 times is with bearing 13 support fixation, main shaft 1 vertically passes abrasive disk 9, the lower end of main shaft 1 is connected with bearing 13 by step (in the described bearing block of this specification bearing being arranged all) 14, preferably step 14 is fixed on the center, the end of bearing 13.The upper end of main shaft 1 is connected with a cross-arm 2 at least, and the upper end of little axle 3 links to each other with cross-arm 2, and there is the small bearing bracket 5 that links to each other with support 6 lower end; The lower end of perhaps little axle 3 links to each other with support 6, and there is the small bearing bracket 5 that links to each other with cross-arm 2 upper end.The fixed gear 18 that is fixed in main shaft 1 is positioned at abrasive disk 9 tops, connects the fluted disc 8 and fixed gear 18 engagements of support 6, also can not establish support 6 as required separately, and small bearing bracket 5 is located at the position, the center of circle of fluted disc 8.Have a hole of placing flap in the fluted disc 8 at least, the setting of hole count can be determined according to the size of fluted disc 8 and the size that needs to grind flap.The below that is positioned at the abrasive disk 9 of fixed gear 18 belows is connected with top chock 17, the spindle gearing that has drive shaft to rotate between top chock 17 and the step 14.

The purpose of this utility model also can reach by following measure: spindle gearing can adopt angular wheel 15 to be fixed in main shaft 1, angular wheel 15 and bevel gear 16 engagements, bevel gear 16 links to each other with an end of power transmission shaft 12, the other end of power transmission shaft 12 connects belt pulley 11, between bevel gear 16 and the belt pulley 11 bearing spider 10 is arranged.The upper end of little axle 3 is positioned at cross-arm 2 tops and screw thread is arranged, and regulates fluted disc 8 with locking nut 4 and is also fixed with the relative position of abrasive disk 9.Support 6 is " door " cribbing, and small bearing bracket 5 is connected in the support 6 of top, fluted disc 8 centers.In addition, around abrasive disk 9, be provided with guard ring 7.

When grinding flap, flap is placed in fluted disc 8 holes, engine rotates belt pulley 11 by belt, and main shaft 1 also rotates thereupon, and (speed of mainshaft is the best below changeing with per minute 60) drives cross-arm 2 rotations.Because fluted disc 8 is to be connected on the cross-arm 2 and to do revolution by small bearing bracket 5, little axle 3, but motionless because of fixed gear 18, forces gear 8 rotations, thereby has reached the purpose of rotation and revolution, makes flap do rotation thereupon and grind with revolution.

The utility model has following advantage compared to existing technology:

1, processing and fabricating is simple, and cost is low;

2, removed heavy manual labor, carried out simultaneously with revolution because the lapping mode of flap is rotation, the flap quality height of grinding, grinding rate is fast;

3, once can grind a plurality of flaps, high efficiency, and the flap that is suitable for various valves grinds.

Fig. 1 is a flap grinder schematic diagram.1-main shaft wherein, 2-support, the little axle of 3-, 4-locking nut, the 5-small bearing bracket, 6-support, 7-guard ring, 8-fluted disc, the 9-abrasive disk, 10-bearing spider, 11-belt pulley, the 12-power transmission shaft, 13-bearing, 14-step, the 15-angular wheel, 16-bevel gear, 17-top chock, the 18-fixed gear, 19-hold-down nut, 20-pallet.

Embodiment: abrasive disk 9 is fixed by bolts on the support 13, main shaft 1 utilizes step 14, top chock 17 to be fixed, angular wheel 15 and bevel gear 16 engagements, belt pulley 11 is connected with motor pulley, the logical square opening in main shaft 1 upper end is adorned a pallet 20, the top is 2 four of cross-arms fixedly, fixing on the cross-arm 2 with hold-down nut 19, adorn a little axle 3 then in every cross-arm 2 ends, the last adjusting with locking nut 4 fixed, the lower end is connected with support 6 by small bearing bracket 5, and support 6 is welded on the fluted disc 8, gear 8 and fixed gear 18 engagements.Around abrasive disk 9, be provided with guard ring 7.
