Description
Technical Field
The utility model relates to a hypoid driven gear shot blasting device, in particular to a gear shot blasting driving protection device.
Background
Gear shot peening (shot peening) is a surface strengthening process widely adopted by factories, namely a cold working process for bombarding the surface of a workpiece by using shot particles and implanting residual compressive stress to improve the fatigue strength of the workpiece, and is widely used for improving the mechanical strength, wear resistance, fatigue resistance and corrosion resistance of parts.
The existing driven gear driving protection tool design has unreasonable parts, the driven gear is uneven in clamping during production and clamping, the driven gear swings left and right along with the impact force of shot in the shot blasting process, and shot blasting coverage is uneven; part of tooth surfaces are sprayed less or the strength of the guide tooth surfaces is insufficient, and the other part of tooth surfaces are sprayed excessively to cause the tooth surfaces to collapse, and in the process of shot blasting from the tooth, the shot is shot into the installation threaded holes of the driven gear due to left and right swing, so that the shot is difficult to clean, and the installation and the use of the gear are affected.
Disclosure of utility model
The utility model aims to solve the problems in the prior art and provides a hypoid driven gear shot blasting driving protection device.
The technical scheme adopted by the utility model is as follows:
A gear shot blasting driving protection device comprises a base assembled on a rotating main shaft in the prior art, wherein a matched angular tooth bushing is connected to the base;
The step shaft at the lower part of the base is connected with a driven tooth positioning seat which is arranged as a disc with a central hole, and screw holes are drilled in the driven tooth positioning seat according to the screw hole positions of the driven gear to be processed, the number of the screw holes is 10-12, and the screw holes are circumferentially distributed along the central line of the disc.
And a group of positioning pins are arranged, each positioning pin is formed into a whole by a truncated cone, a hexagon and a threaded shaft with a stepped shaft, the stepped shaft threaded shaft of each positioning pin is screwed into a screw hole on the corresponding tooth positioning seat to be fastened, and the truncated cone of each positioning pin is jacked into a corresponding positioning hole of the driven gear to fix the driven gear.
On the basis of the technical scheme, the following further technical scheme is provided:
The base is kept horizontal by a support plate of the device; in addition, a series of unthreaded holes are arranged on the tooth positioning seat.
The tool material of the utility model is made of impact-resistant metal material.
The utility model has the beneficial effects that: the tooling provided by the utility model is universal, simple in structure, convenient to replace in a special structure of the pin, and quick in workpiece replacement, and only the slave tooth positioning seat is required to be replaced according to different products; because the locating pin is adopted to be in locating connection with the tooth, the workpiece can rotate along with the shot blasting tool, the workpiece cannot slide along with the impact movement of the shot, the spiral bevel gear of a processed product is ensured to run stably by the tooth, the processing surface of the tooth surface is protected to be uniform, the shot is completely impacted and covered, the compressive stress is uniformly distributed, and the service life of the gear is prolonged. The conical design plays a role in blocking wires, the workpiece is suspended to prevent the pill from entering the screw hole of the gear, and manual cleaning in subsequent processing is reduced.

FIG. 1 is a front view of the present utility model;
fig. 2 is a front view of the slave tooth positioning seat 4 of fig. 1;
Fig. 3 is a front view of the positioning pin 5 in fig. 1.
Description of the embodiments
As shown in fig. 1, the gear shot blasting driving protection device provided by the utility model comprises a base 2 which is assembled on a rotating main shaft of a shot blasting machine in the prior art, wherein a matched angular tooth bush 3 is connected on the base 2.
The step shaft at the lower part of the base is connected with a slave tooth positioning seat 2, the slave tooth positioning seat is sleeved on the main shaft of the equipment through a central hole of the base 2, and the base 2 is connected with a supporting plate 1 through a bottom end 2a to keep horizontal balance.
As shown in fig. 1 and 2, the slave tooth positioning seat 4 is a disc with a central hole 4a, and has good dynamic balance, so that the slave tooth positioning seat moves stably in the process of moving together with the rotating main shaft of the equipment; the jitter caused by other shapes is avoided;
According to the positions of threaded holes of the driven gear 8, the threaded holes 4c are correspondingly drilled from the tooth positioning seat 4, the number of the threaded holes is 10-12, and the threaded holes are circumferentially distributed along the center line of the disc and are used for being screwed into the positioning pins 5 in the later stage; in addition, a series of unthreaded holes 4b are arranged on the slave tooth positioning seat 4; each time the product is processed, the corresponding tooth positioning seat is selected according to different processed product models, and the positioning pin 5 is screwed on.
A group of positioning pins 5 are arranged, each positioning pin 5 comprises a truncated cone 5a, a hexagon 5b and a threaded shaft 5c with a stepped shaft, the threaded shaft 5c of the stepped shaft is screwed into a screw hole 4c on the tooth positioning seat 4, then fastened through the hexagon 5b, a driven gear 8 to be processed is placed, each truncated cone 5a is jacked into a corresponding positioning hole of the driven gear 8, and the driven gear 8 is supported and fixed.
Because the locating pin is adopted to be in locating connection with the driven gear, the driven gear can rotate along with the shot blasting tool, and does not slide along with the impact movement of the shot, the spiral bevel gear of a processed product is ensured to run stably by the gear, the processing surface of a tooth surface is protected to be uniform, the shot is completely covered by impact, and the compressive stress is uniformly distributed.
