Description
Technical field
The utility model relates to rivet make-up machinery field, especially for the rivet driver of the products such as the assembling chair back.
Background technology
Rivet refers in riveted joint, and utilize self-deformation or interference to connect by the part of riveting parts, it utilizes the magnitude of interference of rivet and lock body opening to rivet.And operating personnel again practical operation rivet driver carry out beat rivet work time, one as the products such as the chair back complete riveter nail step after, need change the chair back, repeat beat rivet work, the time changed in the middle of this is very short, but also required time differs according to the quantity situation of different operating personnel.The general switched electronic device that arranges stops to control motor or opens; but this extremely bothers, and motor also needs 1-2 time second from starting to normal operation, and this time may enough change chair back product; and the frequent start-stop of motor, larger to the loss ratio of motor.
Utility model content
The purpose of this utility model solves the problems of the technologies described above, and provides a kind of pause device controlled to rivet driver.
Technical solution of the present utility model is: a kind of controlled pause device of rivet driver, comprise fuselage and the main shaft for driving rivet driver to run, comprise and be rotationally connected by axle the cross bar be arranged in fuselage, one end of described cross bar arranges pedal, and the other end arranges extension spring; Described cross bar arranges on extension spring one end and connects stretching bar again, described stretching bar connects the connecting rod be piercing in outside fuselage, described connecting rod is fixedly connected with the second cross bar again, second cross bar connects on the relative other end of connecting rod at it and connects pin, described second cross bar is connected on fuselage by being rotationally connected the second rotating shaft, corresponding pin position arranges axle sleeve with described main shaft, and described axle sleeve follows spindle synchronous rotation through axle sleeve to propping up on main shaft by bolt; Described pin can be close to axle sleeve while pedal rises to range, and is stoped the rotation of main shaft by bolt blocks.
Operating personnel are when changing the product needing riveter to follow closely, and need machine to suspend for a moment, whole event is ofer short duration; if it is cumbersome to go shutdown to start shooting specially again; so a design pause device, under non-stop-machine state, change product for operating personnel, accelerate operating efficiency.
As preferably, described pin is rotationally connected with the base plate be arranged on fuselage by turning cylinder, the position that described second cross bar is fixedly connected with pin is positioned at the side of turning cylinder, and the other end of pin can enter into bolt by the adjustment of the second cross bar and follows the circular motion route of main axis or depart from this moving line.In order to strengthen the frictional force of pin to axle sleeve, so arranging base plate to strengthen the support force of pin, shortening the movement travel of pin thus strengthening active force to axle sleeve.
As preferably, the side that described second cross bar connects pin is fixedly connected with one again for being close to the friction lever of main shaft while rising to range at pedal.In order to strengthen the sensitivity of pause device further, when needs stop, can stopping immediately.So arrange a friction lever again in order to strengthen the frictional force to main shaft.
As preferred further, described friction lever comprises extension, bending part and friction head; Described bending part is extended the top to main shaft by extension, and the lower surface of friction head is contacted with the upper surface of main shaft.If the contacts side surfaces of friction head and main shaft, friction head is easily flicked, and needs larger power that friction head is contacted with main shaft.And if upper and lower faces contact, the gravity of friction head self also can become a part for frictional force.
As further preferred, the side of described friction head and the contacts side surfaces of axle sleeve.The increasing friction force by increase contact area.
As preferably, the turning cylinder on described base plate will extend to friction lever place plane, and for limiting the pendulum angle of friction lever.This is a safeguard protection design.The turning cylinder extended departs from away after rupturing with the second cross bar after may be used for preventing friction lever from being flicked by main shaft.
As preferably, described fuselage arranges motor, described motor connects driving wheel, and driving wheel is connected to the main wheel be arranged on main shaft by belt transmission.If main shaft is directly by driven by motor, and pause device directly suspends main shaft, is just easy to make the motor shaft in motor stuck.Motor shaft in present motor still can rotate, and namely drives driving wheel idle running.
The utility model beneficial effect is:
This pause device can control the time of time-out with the custom of operating personnel, and simple to operate, suspends sensitivity strong, also can not injure machine shaft.
