Detailed description of the invention
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings:
A kind of drum-type brake pad outer arc grinding machine with abrasion limit machining functions, by notch cuttype support the 1st, outer arc grinding assembly the 2nd,
The 3rd, mold drive assembly weares and teares the limit composition such as grinding assembly 4.Described outer arc grinding assembly 2, is arranged on notch cuttype support 1
On the dovetail guide 5 of the low transverse plane in right side, and can move along dovetail guide direction, its structure is with on tradition outer arc grinding machine
Grinding assembly is completely the same.Described mold drive assembly the 3rd, wear and tear limit grinding assembly 4 be installed on movable table 6,
This workbench is arranged on the rectangular guideway 7 of high transverse plane on the left of notch cuttype support 1, rectangular guideway 7 orientation and outer arc
The emery wheel axis of grinding assembly 2 is parallel, and movable table 6 moves along guide rail 7 direction, is used for adjusting mold 28 and outer arc
Distance between abrasive grinding wheel.
Described mold drive assembly 3, is arranged on movable table 6, can be along outer arc abrasive grinding wheel axle with workbench 6
Axis direction move, for regulating distance between mold 28 and outer arc abrasive grinding wheel.Mold drive assembly structure and biography
Being similar to of system structure, simply its lower end increases a sprocket wheel 8, limits the main shaft assembly in grinding assembly 4 by chain with abrasion
Sprocket wheel 19 on 10 is connected.Mold 28 rotates simultaneously, by sprocket wheel the 8th, chain, sprocket wheel 19 drive shaft assembly 10 turns
Dynamic, and then drive the cam 9 of main shaft assembly 10 upper end by a constant-speed ratio rotation.
Described abrasion limit grinding assembly 4, the 11st, is moved mounting seat the 12nd, motor by main shaft assembly the 10th, displacement transmission mechanism
13rd, belt the 14th, transition axis assembly the 15th, wear and tear limit grinding wheel spindle assembly the 16th, rolling guide-rail pairs 17, balance weight mechanism 18 forms.
Wherein, displacement transmission mechanism the 11st, motor the 13rd, transition axis assembly the 15th, the limit grinding wheel spindle assembly 16 that weares and teares is arranged on mobile installation
On seat 12, equipped with straight-line rolling guide set 17 between mobile its bottom surface of mounting seat 12 and movable table 6, mobile mounting seat
12 can be along guideway 17 side-to-side movement.Balance weight mechanism 18 is connected by steel wire rope with mobile mounting seat 12, is adapted to assist in shifting
The backhaul of dynamic mounting seat 12.
Described main shaft assembly 10, is packed on movable table 6 by screw, and its upper end is supporting with product specification equipped with one
Cam 9, its lower end, equipped with a sprocket wheel 19, is connected with the sprocket wheel 8 in mold drive assembly 3 by chain, i.e. main shaft assembly
10 and mold drive assembly 3 share a set of power-driven system.
Described displacement transmission mechanism 11, the 21st, is fixed seat 22 by roller the 20th, axle and forms, and fixing seat 22 is solid by screw
It is scheduled in mobile mounting seat 12.Roller 20 outer round surface contacts all the time with cam 9 outer round surface.Different product abrasion limit adds
When work parameter is different, need to change cam, and regulate the axial location of axle 21, outside making roller 20 outer round surface with cam 9
Circular surfaces contacts all the time.Cam 9 and balance weight mechanism 18 coordinate, and drive whole Mobile base 12 to seesaw, and then drive mill
Damage limit grinding wheel spindle assembly 16 and complete feeding grinding and the reciprocating motion of unloaded backhaul.
Described abrasion limit its upper end of grinding wheel spindle assembly 16 is sleeved in the hole of hollow shaft 23 of transition axis assembly 15, passes through
Right-angled intersection connects, and is used for transmitting power, and passes through pull bar 24 nose threads axial restraint, and bearing block 25 is passed through in its lower end
It is arranged on mobile mounting seat 12 side plate.Between two abrasion limit emery wheels 26 on it for the abrasion limit grinding wheel spindle assembly 16 equipped with
One spacer 27.When product specification is different, it may be necessary to change this each set, even change emery wheel 26.
Brake block is to be positioned in the positioning segmental arc 30 of mold by its intrados.For the drum-type brake pad of non-equal thickness, in it
Arc and outer arc center of rotation are misaligned, ensure that positioning segmental arc 30 center of position brake piece and drum-type are stopped during matrix design
Car piece inner arc is to overlap, and mold axle center and drum-type brake pad outer arc center are to overlap, during abrasion limit grinding, and abrasion limit
The feeding depth of emery wheel is continually changing with cam curve.For the drum-type brake pad of equal thickness, its inner arc and outer arc
Pivot is to overlap, and ensures positioning segmental arc 30 center and the mold axle center superposition of position brake piece during matrix design,
It is to say, the pivot of its inner arc of equal thickness drum-type brake pad and outer arc, mold positioning segmental arc center and mold axle center
Being to overlap, during abrasion limit grinding, the feeding depth of abrasion limit emery wheel is fixing, and its cam can become one isometrical takes turns.
First, drum-type brake pad 29 is placed in the locating slot of mold 28 side, is rotated into the grinding of outer arc grinding area with mold
Outer arc, grinding finishes and is rotated into abrasion limit grinding area with mold, and now cam ascent stage curvilinear path forces displacement mechanism 11
Driving Mobile base 12 to move forward, making abrasion limit emery wheel just start grinding abrasion limit with product contact, grinding terminates rear cam and turns
Crossing peak and entering descending branch curve, emery wheel and workpiece disengage, and under balance weight mechanism 18 effect, Mobile base 12 retreats,
So far the outer arc of a workpiece and the grinding of abrasion limit are completed.Changing mold can be with grinding different size, uniform thickness and non-uniform thickness
Product.
