Abstract
The utility model relates to a valve grinder, which belongs to the technical field of grinding. The valve grinder comprises a shell, a cam, a driving rod and a driving shaft. The cam is fixed on the shell by screw threads; sliding pins are fixed on the driving rod passing through the cam, wherein one sliding pin is contacted with the cam, and the other sliding pin is arranged in a guide groove of a driving sleeve at one end of the driving shaft; a spring is arranged between the upper end of the driving rod and the driving sleeve; a bearing is arranged between the upper end of the shell and the driving shaft; a stop lever is fixed on the shell; the stop lever is positioned on the lower end surface of the bearing; and a groove of the fixed stop lever is provided with a small hole which runs through the shell. The valve grinder with the structure omits a pneumatic device and a generator device; the stop lever fixed on the shell can prevent the shell from rotating; lubricating oil can be fed through the small hole; the service life of the valve grinder can be prolonged; and in addition, the valve grinder has small volume, simple structure, low manufacturing cost and convenient use and maintenance.
Description
Technical field
The present invention relates to a kind of valve grinder, belong to the grinding technique field.
Background technology
Now, the grinder that the grinding of valve and valve base is adopted mainly contains two kinds: a kind of is pneumatic lapper, and a kind of is motor-driven mill.Pneumatic lapper drives piston with air pressure, grinds by converting system, gear etc., and this has wearing and tearing with regard to cisco unity malfunction slightly to the sealing requirements strictness of grinder, and parts very easily damage, and service life is short; Motor-driven mill is power with the motor, drives drive link and cam grinds with worm gear, worm speed-down, and motor easily burns, and worm gear, worm screw are easy to wear, and service life is also undesirable, and these two kinds of grinding machine structure complexity, manufactures the cost height, and the maintenance dismounting is loaded down with trivial details.
The utility model content
The utility model provides a kind of power, simple in structure, valve grinder of using easy to maintenance and long service life during by the work of bench drill or electric hand drill.
It is as follows to address the above problem the technical scheme that is adopted:
A kind of valve grinder, composition comprises: shell, cam, drive link, power transmission shaft, cam is fixed on the shell, passes intrinsic sliding pin on the drive link of cam by screw thread, wherein a sliding pin contacts with cam, another sliding pin is positioned at the guide groove of the drive sleeve of power transmission shaft one end, between drive link upper end and the drive sleeve spring is arranged, be provided with bearing between the upper end of shell and power transmission shaft, on the housing of shell, fix a lever, the position of this lever is at the place, lower surface of bearing, fixedly in the groove of lever aperture is arranged, housing is passed in this hole.
Above-mentioned a kind of valve grinder has wear sleeve between described cam and the drive link.
Adopt the valve grinder of this structure, owing to saved pneumatic shuttle and electronic device, this body is long-pending little, simple in structure, it is low to manufacture cost, use easy to maintenancely, because by the power of bench drill or electric hand drill, and fixing lever can prevent that shell from rotating on the shell, but by the aperture apply oil, can prolong the life-span of grinder, wear sleeve can prevent the friction between cam and the drive link, thereby prolongs the service life of grinder.
Description of drawings
Fig. 1 is the structural representation that partly cuts open of the present utility model.
The specific embodiment
With reference to Fig. 1, cam 2 is fixed on the shell 1 by screw thread, pass intrinsic sliding pin on the drive link 3 of cam 2, wherein a sliding pin 6 contacts with cam 2, another sliding pin 7 is in the guide groove of the drive sleeve 8 of power transmission shaft 5 one ends, between drive link 3 upper ends and the drive sleeve 8 spring 4 is arranged, there is rubber suction cups 13 lower end of drive link 3,5 of the upper end of shell 1 and power transmission shafts are provided with bearing 9, fix a lever 10 on the housing of shell 1, lever 10 and shell 1 are for being threaded, and the position of this lever 10 is at the place, lower surface of bearing 9, fixedly in lever 10 grooves aperture 11 is arranged, housing is passed in this hole 11, but by aperture 11 apply oils, can prolong the life-span of grinder.Between cam 2 and the drive link 3 wear sleeve 12 is arranged, wear sleeve 12 can prevent the friction between cam and the drive link, thereby prolongs the service life of grinder.
When matching when grinding to valve and valve seating, on the rubber suction cups 13 of valve vacuum suction to the drive link 3, again this machine is installed on bench drill or the electric hand drill, when bench drill or electric hand drill work, by their power, the power transmission shaft 5 that drives grinder rotates, and slowly rises when rotated and falls rapidly again thereby drive cam 2, makes contacting between valve and the valve seating reach the effect of patting roll extrusion.Drive link 3 and power transmission shaft 5 are rotated synchronously and drive link 3 with respect to drive sleeve play about in the of 8.The reset force of spring 4 can make drive link 3 drive valves fall after rise rapidly.
Claims (2)
1, a kind of valve grinder, composition comprises: shell, cam, drive link, power transmission shaft, cam is fixed on the shell, passes intrinsic sliding pin on the drive link of cam by screw thread, wherein a sliding pin contacts with cam, another sliding pin is positioned at the guide groove of the drive sleeve of power transmission shaft lower end, between drive link upper end and the drive sleeve spring is arranged, it is characterized in that: be provided with bearing between the upper end of shell and power transmission shaft, on the housing of shell, fix a lever, the position of this lever is at the place, lower surface of bearing, fixedly in the groove of lever aperture is arranged, housing is passed in this hole.
2, a kind of valve grinder as claimed in claim 1 is characterized in that: between cam and the drive link wear sleeve is arranged.
