Abstract
The invention discloses a gear local ion nitriding tool and aims to solve the technical problem of ion nitriding. In the gear local ion nitriding tool, sleeve spacing pads (2) are sleeved on a tubular upright post (1) welded in the center of a base plate (4) in turn, and a workpiece gear (3) is sleeved on the sleeve spacing pads (2); the base plate (4) is placed on the workpiece bearing face of a cathode disc; and the feeding tool for use in gear local ion nitriding is equipped with a thermocouple for measuring a temperature, a water-cooled anode cap, ammonia, acetone, a power supply system and a vacuum generation system. The gear local ion nitriding tool has the advantages that: the surface quality and geometric dimensions, which are achieved by the gear local ion nitriding, both meet technical requirements; and the tool is economic and practical.
Description
Technical field
The present invention relates to wheel shaft thermal treatment frock, be specifically related to a kind of gear local ion nitrogenize frock.
Background technology
Ion nitriding is for its charging mode, be that frock but has extremely strict requirement, characteristics because of ion nitriding, the contact site of gear and gear, gear and frock all can not nitrogenize because of shielding, gear and gear spacing are too small, local temperature is too high, causes gear shifting quadrant texturing and influences inner quality; Narrow slit and sharp-pointed angle are all very easily killed arc, cause fusing to burn gear.Demand studying, designing the selective nitriding frock of low-consumption high-efficiency urgently.
Summary of the invention
The present invention discloses a kind of gear local ion nitrogenize frock, and purpose is to solve the problems of the technologies described above.Gear local ion nitrogenize frock is to overlap sleeved separation pad (2) successively on the tubular type column (1) of center, chassis (4) welding.
Described chassis (4) is placed on the cathode disc carrying workpiece face.
The shove charge frock of described gear local ion nitrogenize is equipped with thermometric thermopair, the anode cap of water-cooled; Ammonia, acetone, power supply system and vacuum acquiring system.
The invention has the advantages that: surface quality, the geometrical dimension of the nitrogenize of gear local ion all reach technical requirements; Frock is economical and practical.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is a local ion nitrogenize shove charge tooling drawing.
Among the figure: tubular type column 1, sleeve separation pad 2, workpiece gear 3, chassis 4.
Embodiment
As shown in Figure 1, gear local ion nitrogenize shove charge frock is made of tubular type column 1, sleeve separation pad 2, workpiece gear 3, chassis 4 four parts, is equipped with thermometric thermopair, the anode cap of water-cooled; Ammonia, acetone, power supply system and vacuum acquiring system.4 welding of tubular type column 1 and chassis have requirement to verticality, purpose be guarantee that tubular type column 1 reach a certain height, when chassis 4 does not increase again, the 1 unlikely inclination of tubular type column guarantees contour between string and string simultaneously.Sleeve separation pad 2 is important members, at first considers easy to loading and unloadingly, and sleeve separation pad 2 endoporus and tubular type column 1 must have suitable gap, are 0.5 millimeter; Next considers the height of sleeve separation pad 2, if highly big, the workpiece spacing is big, and piece installing is few, production efficiency is low, if highly little, be unfavorable for the covering of nitrogenize aura layer, and may cause local temperature too high, influence the product inner quality and cause workpiece deformation, when serious, also can melt workpiece, workpiece is scrapped.Its three intensity that will consider sleeve separation pad 2 is guaranteed in loading and unloading and is not caused its distortion when depositing.
The program of piece installing is, tubular type column 1 and chassis 4 weldments are placed on the cathode disc, and sleeved separation pad 2 earlier on the tubular type column 1 at 4 centers, chassis refills a workpiece gear 3, and circulation is carried out; The tubular type column 1 of a string height about 1 meter, but about 3 two ten of cogged workpiece roughly.
To the local nitriding treatment of implementing of gear, the position of Fig. 1 middle gear workpiece 3 surperficial solid line indications is surfaces of the necessary nitrogenize of technical requirements.
Claims (3)
1. gear local ion nitrogenize frock is characterized in that: described gear local ion nitrogenize frock is to overlap sleeved separation pad (2) successively on the tubular type column (1) of center, chassis (4) welding.
2. according to the described gear local ion of claim 1 nitrogenize frock, it is characterized in that: described chassis (4) are placed on the cathode disc carrying workpiece face.
3. according to the described gear local ion of claim 1 nitrogenize frock, it is characterized in that: described gear local ion nitrogenize frock is equipped with thermometric thermopair, the anode cap of water-cooled; Ammonia, acetone, power supply system and vacuum acquiring system.
