Description
Technical field
The utility model belongs to metallic sintered products field, and in particular to a kind of powder metallurgy pressing plate for electric tool.
Background technique
In the case where industry flourishes, it is widely used for electric tool, it is all to add applied to carpenter, Shi Ye, machinery
In work.Electric tool needs pressing plate when filling saw blade to fix.The direction of rotation of pressing plate and saw blade be it is identical, saw blade passes through
Stiction between pressing plate is driven to rotate.
Saw blade pressing plate multi-pass currently on the market crosses keyway and drives saw blade rotation, and this method leads to saw blade discontinuity,
Pressing plate is larger with blade wear, causes electric tool service life short, and dismount difficulty, is unable to satisfy electric tool high-performance
Requirement.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of powder metallurgy pressure for electric tool
Plate, the pressure plate structure is novel, increases electric tool driving force, runs smoothly, convenient disassembly.
In order to solve the above technical problems, the technical solution of the utility model are as follows:
A kind of powder metallurgy pressing plate for electric tool of the utility model, including rounded pressing plate ontology, pressing plate sheet
Through-hole and spline are equipped among body；Spline is arranged in through-hole；The medial surface of pressing plate ontology is equipped with an annular recess；Institute
The annular recess inner ring stated is equipped with a collar flange by through-hole edge direction；The collar flange and one bodily form of pressing plate ontology
At；The medial surface of pressing plate ontology most outer is equipped with a groove, and the lateral surface of the pressing plate ontology is equipped with a multi-diameter shaft.
Preferably, the spline slot length accounts for the 2/3 of through-hole overall length, spline is close to the outside of pressing plate ontology
Face.Through-hole is not completely covered in the spline of the utility model, and when the purpose is to install convenient for spline and axis, keyway can be complete
It is contacted entirely with the output shaft of electric tool.Preferably, the through-hole is close to be equipped with cyclic annular wedge at pressing plate ontology medial surface
Shape face.Cyclic annular lozenges is directed at during installation convenient for axis and enters through-hole.
Preferably, the depth of groove is 8.5mm, when dismounting, spring catch can be real by being pressed into or releasing groove
Now dismount.
Preferably, the collar flange is 1.5-2mm relative to the height of annular recess bottom；Collar flange edge
The width of pressing plate ontology radial direction is the half of annular recess.Annular recess is mainly used for reducing pressing plate weight, and cyclic annular convex
Edge is designed for guaranteeing saw blade strength of compressive plate.
The utility model has the beneficial effects that using the powder metallurgy pressing plate of above-mentioned technical proposal, durable and structure
Novelty, spline increase driving force, torque is uniform and runs smoothly, and medial surface groove is used for transmitting saw blade torque
In the positioning of saw blade, easy disassembly.
Detailed description of the invention
Fig. 1 is pressure plate structure figure；
Fig. 2 is the right side plan view in Fig. 1；
Fig. 3 is the left side plan view in Fig. 1；
In figure, ontology 1, spline 2, collar flange 3, annular recess 4, groove 5, multi-diameter shaft 6.
Specific embodiment
As shown in Figure 1, 2, 3, a kind of powder metallurgy pressing plate for electric tool of the utility model, including rounded pressure
Plate ontology 1 is equipped with through-hole and spline 2 among pressing plate ontology 1；Spline 2 is arranged in through-hole；The medial surface of pressing plate ontology 1
It is equipped with an annular recess 4；4 inner ring of annular recess is equipped with a collar flange 3 by through-hole edge direction；The ring-type
Flange 3 and pressing plate ontology 1 are integrally formed；The medial surface of pressing plate ontology 1 most outer is equipped with a groove 5, the pressing plate ontology 1
Lateral surface is equipped with a multi-diameter shaft 6.
As a preferred embodiment of the present invention, the spline slot length accounts for the 2/3 of through-hole overall length, and spline is close to pressure
The lateral surface of plate ontology 1.Through-hole is not completely covered in the spline 2 of the utility model, and the purpose is to pacify convenient for spline 2 and axis
When dress, keyway can be contacted with the output shaft of electric tool completely.Preferably, the through-hole is close in pressing plate ontology 1
Lateral position is equipped with cyclic annular lozenges.Cyclic annular lozenges is directed at during installation convenient for axis and enters through-hole.
As a preferred embodiment of the present invention, 5 depth of groove is 8.5mm, and when dismounting, spring catch can pass through pressure
Enter or release groove, realizes dismounting.
As a preferred embodiment of the present invention, the collar flange 3 is relative to the height of 4 bottom of annular recess
1.5-2mm；Collar flange 3 along pressing plate ontology radial direction width be annular recess 4 half.Annular recess 4 is mainly used for
Pressing plate weight is reduced, and collar flange 3 is designed for guaranteeing saw blade strength of compressive plate.
All structures on the pressing plate ontology 1 of the utility model pass through powder metallurgically manufacturing technology and are integrally formed, powder
Metallurgy is to produce metal powder or use the mixture of metal powder or metal powder and non-metal powder as raw material, by forming
And sintering, the technology of manufacture metal material, composite material and various types product.Devise saw blade pressing plate die for special purpose
Tool produces the one-pass molding of saw blade pressing plate by PM technique, and at low cost, high production efficiency is suitble to produce in enormous quantities.This
The compacting template that the pressing plate of invention can be used two lower three is formed.The pressing plate is durable, in use, saw blade is installed on pressure
On the multi-diameter shaft of plate ontology 1, saw blade is fixed with top board and pressing plate ontology 1, output shaft and the spline 2 of electric tool are matched
It closes, transmits power, shell is rotated by spring catch to groove 5, can realize saw blade by spring catch being pressed into or being released groove 5
Fixed and dismounting, improves service efficiency.
