Abstract
An overload protection device of a coiling machine mobile core cutter holder comprises an output shaft, a transmission shaft, a spring device and a positioning bracket, wherein the output shaft comprises a connecting rod, a connecting part and a convex part arranged at the bottom of the connecting part; the transmission shaft comprises a rod part, a connecting part and a concave part at the top part of the connecting part; and the spring device is an adjusting mechanism for overload protection and comprises a bush, a spring and an adjusting screw. By adopting the structure, a screw rod can automatically stop under over-big stress, thereby protecting mechanical parts from being damaged.
Description
Technical field
This creation relates to the overload protection arrangement that coiling machine moves the core tool rest, but refers to that especially a kind of coiling machine is at stressed automatic pause running when excessive, the overload protection arrangement of unlikely damage component of machine.
Background technique
Core cutter and core tool rest are the important component part of coiling machine, before the spring winding process, and need be according to the size of spring diameter and the first position height of regulating the core tool rest of thickness of Spring Steel Wire.The pellet that the core tool rest has been installed moves up and down is by the motor output shaft drive lead screw, and screw mandrel drives the screw that is fixed on the pellet and moves up and down and finish.When moving to suitable position,, must firmly be fixed on pellet on the front wallboard with fastening device six direction before and after up and down because the core tool rest will frequently stand to cut off the impact force of steel wire.When needs are made the spring of other specification, then need all fastening devices have all fully been loosened, drive pellet with motor again.In the practice, often take place the operator because of loosen not enough or other faults to cause pellet to move not smooth, damaged expensive drive lead screw and screw.
The design people, has breakthrough through concentrating on studies and putting into practice finally at this problem.
Summary of the invention
Main purpose of the present invention provides the overload protection arrangement that coiling machine moves the core tool rest.
To achieve these goals, now its technological scheme is described as follows:
Coiling machine moves the overload protection arrangement of core tool rest, is to be connected driving by transmission shaft with screw on screw mandrel and the pellet, comprises an output shaft, transmission shaft, and the overload protection in realizing driving under the acting in conjunction of spring assembly and locating support, wherein:
One output shaft comprises a connecting rod and joint, and the joint bottom is provided with a bump;
One transmission shaft comprises a bar portion and a joint, and the joint top is provided with depressed part, and
One spring assembly is the controlling mechanism of overload protection, comprises a lining, spring and adjusting screw.
Described coiling machine moves the overload protection arrangement of core tool rest, and wherein the connecting rod of this output shaft upper end is to be connected with reducing motor under the support of locating support.
Described coiling machine moves the overload protection arrangement of core tool rest, the wherein bump of this output shaft lower end joint and transmission shaft depressed part engagement.

Embodiment
Coiling machine moves the overload protection arrangement (100) of core tool rest; be to be connected driving with the screw (31) of screw mandrel (20) and pellet (30) by transmission shaft (10); comprise an output shaft (40), transmission shaft (10); and the overload protection under the acting in conjunction of spring assembly (50) and locating support (60), having realized driving, wherein:
One output shaft (40), its top comprise a connecting rod (41), and are connected with reducing motor (70) under the support of locating support (60); Its bottom comprises a junction (42), is provided with the bump (421) of an approximate V-arrangement in joint (42) bottom, with depressed part (121) engagement on transmission shaft (10) top.
One transmission shaft (10), be connected with screw mandrel (20), comprise a bar portion (11), joint (12), joint (12) top is provided with depressed part (121), this depressed part (121) is similar to V-arrangement, is the match mechanism with the engagement of the bump (421) of output shaft (40) bottom joint (42).
One spring assembly (50) is the controlling mechanism of overload protection, comprises a lining (51), spring (52) and adjusting screw (53), and when adjusting screw (53) when compressing, it is stressed to strengthen overload, on the contrary, transships stressed diminishing.
The stressed principle of spring assembly (50) by this, and in conjunction with the coupled condition of output shaft (40) bump (421) with transmission shaft (10) depressed part (121), it is normal engageable when stressed, departing structural principle when overload is stressed, the torque that restriction passes to screw mandrel is confined in certain scope, has avoided the damage of overload rotation to component of machine.
In sum, only creating an embodiment for this, is not the restriction to this case design, and all equivalent variations of doing according to the designing institute of this case all fall into the protection domain of this case.
