Abstract
The patent discloses an in a charging tray for two end -face grinding of spring, including the charging tray body, the charging tray body is the cylinder, evenly distributed has the locating hole on the circumference of charging tray, be provided with in the locating hole and grind the cover, grind cover both sides protrusion in the same length of charging tray terminal surface, grind the cover with locating hole interference fit, it has the stereoplasm layer to grind the outer cladding of cover, the utility model provides an in a charging tray for two end -face grinding of spring, solved and carried out the problem with high costs that thermal treatment brought to the mill, replace the wearing and tearing of charging tray in the mill cover of charging tray through the protrusion, improved the life of charging tray.
Description
Technical field
This utility model relates to spring Double face grinding parts, particularly for the charging tray of spring Double face grinding.
Background technology
In order to increase spring in use, contact area between spring end face and its base surface, spring is all to need grinding, but common grinding is all to be positioned in the support limit hole of charging tray by the spring of molding, carry out restricted spring vertical, utilizing driven by motor charging tray and charging tray emery wheel opposing upper and lower to rotate, spring is being carried out grinding to polish both ends of the spring face.
Patent No. 201220277217.3 Chinese patent literature discloses a kind of spring double-ended grinding machine, particularly relates to the charging tray of a kind of spring double-ended grinding machine.Disclose a kind of charging tray for spring double-ended grinding machine, including a circular charging tray, charging tray center is provided with a centre bore, charging tray is provided with station hole, at least provided with one group of station hole on charging tray, equal with the station hole in group and the distance between the charging tray center of circle, equal with the distance between adjacent of the station hole in group.
In above-mentioned patent documentation, the raw material of abrasive disc is typically spheroidal graphite cast-iron, spring in charging tray in grinding process because charging tray hardness low, generally when wheel grinding is to charging tray, charging tray can be caused to be worn seriously, once charging tray may wear to a certain degree, and charging tray just can only be scrapped, simultaneously as charging tray is oversize, if charging tray is carried out heat treatment, the hardness improving charging tray then can cause the raising of cost.
Utility model content
This utility model is intended to provide a kind of charging tray for spring Double face grinding, solves original charging tray hardness low, generally can be ground to charging tray when wheel grinding spring, can cause charging tray serious wear；If charging tray is carried out heat treatment, cause the problem that heat treatment is difficult and heat treatment cost is high.
In base case: for the charging tray of spring Double face grinding, including charging tray body, charging tray body is cylinder, hole, location it is evenly distributed with on the circumference of charging tray, location is provided with grinding set in hole, grinding set both sides protrude from the same length of charging tray end face, grinding set and hole, location interference fit, and grinding set is coated with hard layer.
In above-mentioned base case, the circumference of charging tray is evenly distributed with hole, location, the grinding set of hard layer it is provided with in hole, location, grinding set protrudes from the charging tray both sides same length of end face, grinding set protrudes from charging tray, the most in use can substitute the grinding of charging tray by using grinding set, hard layer outside grinding set can effectively improve the grinding set life-span under the grinding of emery wheel simultaneously, grinding set both sides protrude from the same length of charging tray end face, so install relatively good regulation, will not differ because of length and regulate inconvenient problem, grinding set can be positioned in the case of without other parts by interference fit.
Preferred version one, based on the further optimization of scheme, wherein side protrudes from the grinding set of charging tray and is provided with circular orientation boss, and circular orientation boss is fitted with charging tray end face；During installation, by circular orientation boss, the installation of grinding set is carried out spacing, install conveniently.
Preferred version two, based on the further optimization of scheme, hard layer is by quenching, carburizing or nitriding, and heat treatment so is the method for conventional increase metal material hardness, and outsourcing heat treatment process is the most relatively cheap, and cost can be relatively low.
Preferred version three, based on the further optimization of scheme, grinding set and be ground matched in clearance between spring, and be ground the end face of spring higher than grinding set 3mm；Grinding set and be ground matched in clearance between spring, can be supported from the axial outline being ground spring by grinding set and be ground spring, prevent it from tilting, with being higher than after grinding set 5mm when being ground spring, spring can be taken out of from grinding set by emery wheel in grinding process, when then there will be grinding set serious wear less than 3mm.
Preferred version four, based on the further optimization of scheme, the spacing between grinding set is more than 8mm, between grinding set when being smaller than 8mm, the metallic particles being ground is difficult to row and cuts smooth and easy.
Accompanying drawing explanation
Fig. 1 is that the structure of this utility model embodiment is intended to；
Fig. 2 is the structural representation of grinding set 2.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: charging tray 1, grinding set 2, circular orientation boss 21, driving hole 3.
Embodiment is the most as shown in drawings: in the charging tray for spring Double face grinding, including charging tray 1, charging tray 1 is in cylinder, hole, inside and outside two-layer location it is evenly distributed with on the circumference of charging tray 1, in hole, location, interference fit has grinding set 2, and on one end periphery of grinding set 2, radially protruding has circular orientation boss 21, the end face laminating of circular orientation boss 21 and charging tray 1, being coated with hard layer in grinding set 2, the hard layer of grinding set 2 is by quenching, carburizing or Nitrizing Treatment.
Mounted grinding set 2 circular orientation boss 21 thickness protrudes from the length of charging tray 1 equal to grinding set 2 other end；Grinding set 2 and be ground matched in clearance between spring, and it is ground the end face of spring higher than described grinding set 3～5mm；Spacing between grinding set is more than 8mm.
The circumference of charging tray 1 is evenly distributed with hole, location, the grinding set 2 of hard layer it is provided with in hole, location, grinding set 2 protrudes from the charging tray 1 both sides same length of end face, grinding set 2 protrudes from charging tray 1, the most in use can substitute the grinding of charging tray 1 by using grinding set 2, hard layer outside grinding set 2 can effectively improve the grinding set 2 life-span under the grinding of emery wheel simultaneously, and grinding set 2 can be positioned in the case of without other parts by interference fit.
