Abstract

The utility model discloses a grinding fixture for gear inner holes. The grinding fixture is mainly a ground film fixture after heating of gear inner holes. The structure of the grinding fixture comprises a push rod mechanism, an installation chuck, an elastic film plate, a clamping jaw and the like, the elastic film plate is pushed by an air cylinder push rod to deform and drive the clamping jaw to act, and accurate positioning and clamping and loosing actions of workpieces are achieved. According to the grinding fixture for gear inner holes, the adjusting ring jumping time during original gear inner hole grinding is saved, the grinding efficiency is improved by more than 30%, the product accuracy is guaranteed, and the grinding fixture has certain applicability in gear processing manufacture industry.

Description

The bore clamp
Technical field
The utility model relates generally to the technical field of Gear Processing, relates in particular to a kind of carburizing and quenching gear heat and grinds afterwards the quick-clamping of endoporus, the anchor clamps of high manufacturing accuracy.
Background technology
In Gear Processing, for the disk gear that endoporus is arranged, tooth processed all is to process take endoporus as benchmark basically before the heat, it is the impact that reduces heat treatment deformation after the heat, on Gearmaking Technology, the method mill endoporus that adopt folder pitch circle, school pitch circle, the precision of assurance finished product gear more.Exploitation quick-clamping, the accurate novel clamp of location are the demands that realizes the processing in enormous quantities of this disk gear, and the utility model clamp has changed the practice of former school pitch circle, have easy to operate, quick, the positioning accuracy advantages of higher.
The utility model content
The utility model purpose is exactly the defective that can not produce in enormous quantities in order to remedy prior art dish-type gear, and a kind of bore clamp is provided.
The utility model is achieved through the following technical solutions:
A kind of bore clamp, include transfer bar mechanism, chuck for installing, elasticity membranous disc and jaw, described chuck for installing is the reeded circular discoid body of a side band, and there is a through hole chuck for installing center, install in the through hole and be penetrated with push rod, described installing card dribbling groove side is installed with an elasticity membranous disc, three coulisses with T-shaped chute of uniform installation on the described elasticity membranous disc, be fixedly connected with the jaw of adjustable position on the described coulisse, jaw adopts bolt, pressing plate is fastening, be furnished with through hole between the adjacent coulisse on the described elasticity membranous disc, be positioned on the chuck for installing of through hole rear support column is installed, the adjustable axial location piece of radial position is installed on the described support column.
Described axial location piece is spaced apart between adjacent coulisse.
Described push rod promotes to consist of transfer bar mechanism by cylinder, and the stroke that push rod promotes the distortion of elasticity membranous disc generally is not more than 1 millimeter.
Described elastic membrane disc thickness is the 3-5 millimeter, and material is 65Mn, and the two sides grinding of elasticity membranous disc is parallel.
Connection between described each parts is with bolts, and each part and overall structure are distribution equalizing structure.
Operation principle: the elasticity membranous disc uses the bolted of circumferencial direction on chuck for installing when fabrication and installation.Work as cylinder charge, transfer bar mechanism promotes the elasticity membranous disc, overcoming the moving jaw of elasticity membranous disc elastic band opens, can fill workpiece this moment, after workpiece utilizes pitch-line chuck or three same footpath length bars to locate in anchor clamps, cylinder is oppositely inflated, and transfer bar mechanism is return, and workpiece is clamped under the elastic force effect of elasticity membranous disc.Because three jaws are certainly to grind locating surface under free state on grinding machine, so the centering precision of its three-jaw is very high, satisfy the Gear Processing required precision fully.
The utility model has the advantages that:
Easy to operate, quick, positioning accuracy is high, and working (machining) efficiency is high, under the condition that guarantees Product Precision, can improve grinding efficiency more than 30%.
Description of drawings
Fig. 1 is the structural front view after the utility model is removed jaw.
Fig. 2 is structure left view of the present utility model.
The specific embodiment
As shown in Figures 1 and 2, a kind of bore clamp, include transfer bar mechanism, chuck for installing 1, elasticity membranous disc 8 and jaw 3, described chuck for installing 1 is the reeded circular discoid body of a side band, and there is a through hole chuck for installing 1 center, install in the through hole and be penetrated with push rod 6, described chuck for installing 1 band groove side is installed with an elasticity membranous disc 8, three coulisses 2 with T-shaped chute of uniform installation on the described elasticity membranous disc 8, be fixedly connected with the jaw 3 of adjustable position on the described coulisse 2, jaw 3 adopts pressing plate 4 and bolted, be furnished with through hole between the adjacent coulisse 2 on the described elasticity membranous disc 8, be positioned on the through hole rear chuck for installing 1 support column 9 is installed, the adjustable axial location piece 7 of radial position is installed on the described support column 9, the location that radial position is adjustable satisfies different large small workpiece.Described axial location piece 7 is spaced apart between adjacent coulisse 2.Described push rod 6 promotes to consist of transfer bar mechanism by cylinder, and the stroke that push rod 6 promotes 8 distortion of elasticity membranous disc generally is not more than 1 millimeter, in jig Design, should according to the size of jaw 3 unlatchings, calculate the locating dimension of this push rod.Described elasticity membranous disc 8 thickness are the 3-5 millimeter, and material is 65Mn, and the 8 two sides grindings of elasticity membranous disc are parallel, guarantee coulisse 2 and the firm and symmetric deformation of jaw 3 assemblings.Connection between described each parts adopts bolt (5,10) to connect, and each part and overall structure are distribution equalizing structure, thereby have guaranteed the homogeneous deformation of elasticity membranous disc 8.When different circle-dividing diameter workpiece change product, should adjust in advance jaw 3 positions, reserve the autogenous grinding surplus.The axial location benchmark of workpiece should design on chuck for installing 1, accurately locates to guarantee workpiece.Work as cylinder charge, transfer bar mechanism promotes elasticity membranous disc 8, utilizing elasticity membranous disc 8 elastic force to drive jaw 3 opens, can fill workpiece this moment, after workpiece utilizes pitch-line chuck or three same footpath length bars to locate in anchor clamps, cylinder is oppositely inflated, and transfer bar mechanism is return, and workpiece is clamped under the elastic force effect of elasticity membranous disc 8.Because three jaws are certainly to grind locating surface under free state on grinding machine, so the centering precision of its three-jaw is very high, satisfy the Gear Processing required precision fully.
