Component stop motion.
In the present embodiment, buffer brake device 3 is contracting brake.
Under the normal working condition of electric injection molding machine, servo motor 1 runs well, and contracting brake is in energization shape
State, will not export braking torque, the output shaft normal rotation of servo motor 1, only servo motor 1 be in abnormal state or
When burst power-off, the automatic pick of contracting brake meeting at this time is exported on stable braking torque to output shaft 11.
Preferably, contracting brake is electromagnetic brake brake.
Wherein, electromagnetic brake brake includes Breake Electromagnet and block brake two parts, Breake Electromagnet by iron core,
Armature and coil three parts composition, block brake include brake wheel, brake shoe, lever and spring, and brake wheel is with motor mounted in same
In root shaft.
Electromagnetic brake brake can still export braking torque under the blackout condition of burst, i.e., when entire injection molding machine is prominent
Hair have a power failure when, electromagnetic brake brake also can automatic pick, to export stable torque to carry out buffer-braking.
In the present embodiment, attachment base 2 is the prism bodily form, and first pulley 51 is set in attachment base 2, two of attachment base 2
The through-hole 21 passed through for conveyer belt 50 is offered on side.
With reference to Fig. 1, attachment base 2 is set as the prism bodily form, and the inside of prism is arranged first pulley 51, can effectively mention
High spatial occupancy reduces the volume of entire buffering braking mechanism, facilitates and carry out installation assembly.
Wherein, attachment base 2 is directly anchored on fixed device by screw, and buffer brake device 3 is fixed on attachment base 2
Prism top surface.
First pulley 51 is set on the output shaft 11 of servo motor 1, and output shaft 11 and first pulley 51 pass through expansion sleeve
Connection.
Expansion sleeve is also known as expansion coupling sleeve, is the advanced basic components of one of mechanical connection, in the connection of wheel and axis

Device, when bearing load, by expansion sleeve and axis combination pressure and together the frictional force that generates transmits torque, axial force or two
The combined load of person.
When servo motor 1 runs well, first pulley 51 is transmitted by expansion sleeve on the output shaft 11 of servo motor 11
Output torque to the moving component of electric injection molding machine, drive the moving component of electric injection molding machine to move.
By the way that expansion sleeve is arranged, so that keyless joint between output shaft 11 and first pulley 51, couples reliable and stable, intensity
It is higher, and installation and convenient disassembly.
Further, it can also be attached by spline flat key between first pulley 51 and output shaft 11, i.e., it is logical
Spline flat key is crossed to substitute expansion sleeve.
In the present embodiment, fixed device 4 is flange plate, flange plate be it is rectangular, servo motor 1 is set to the one of flange plate
Side, attachment base 2, buffer brake device 3 and transmission component 5 are set to the other side of flange plate.
Wherein, circular hole is provided on flange plate so that the output shaft of servo motor 1 passes through, servo motor 1 and flange plate it
Between fixed by screw connection, fixed between attachment base 2 and flange plate by screw connection, buffer brake device 3 passes through spiral shell again
Silk is fixed on attachment base 2.
The side of flange plate is set by setting flange plate and by servo motor 1, attachment base 2, buffer-braking are filled
Set 3 and transmission component 5 be set to the other side of the flange plate opposite with servo motor 1, conveniently entirely can buffer braking machine
The installation and maintenance of structure, operator only need successively to install all parts from left to right, install very convenient.
In the present embodiment, servo motor 1 is electrically connected with driver respectively with buffer brake device 3, passes through driver control
The switch of servo motor 1 and buffer brake device 3.
Wherein, driver is not shown comes out, and when 1 state of servo motor is abnormal, driver detects that servo motor is worked as
Preceding abnormality, it will the power input of cutting servo motor 1, servo motor 1 stop output torque, meanwhile, driver is also
Buffer brake device 3 can be controlled, so that buffer brake device 3, which is attracted, generates stable braking torque, braking torque passes through transmission
Component 5 is transmitted on the moving component of electric injection molding machine, so that moving component stop motion.
In another case, i.e., when entire electric injection molding machine all happen suddenly power failure when, at this time driver, servo motor 1 and
Buffer brake device 3 is all without power input, and the output shaft 11 of servo motor 1 stops output torque, and buffer brake device 3 exists
In the case where not having power input, meeting automatic pick exports stable braking torque by friction, so that buffer brake device 3
Braking torque can be still generated in the case where entire electric injection molding machine happens suddenly and has a power failure, plays the role of buffering, to electronic note
The moving component of molding machine is braked.
By the way that buffer brake device 3 is arranged, it can either be in abnormal state in servo motor 1, driver has power supply defeated
Play the role of buffer-braking in the case where entering, and can not all there is no the case where power input in servo motor 1 and driver
Under play the role of buffer-braking, can effectively cope with a variety of different risk situations.
In the present embodiment, the second belt wheel 52 is located on same vertical plane with first pulley 51, and the second belt wheel 52 is located at first
Below belt wheel.
Second belt wheel 52 is located on same vertical plane with first pulley 51, braking torque and servo motor can be facilitated
The stable moving component for being transferred to electric injection molding machine of the output torque of 1 output shaft 11, thus effectively to electric injection molding machine
Moving component controlled.
