Specific implementation mode
To make the foregoing features and advantages of the present invention clearer and more comprehensible, special embodiment below, and coordinate attached drawing, make detailed
It is carefully described as follows, but the present invention is not limited thereto.
With reference to figure 1 and Fig. 2
A kind of to prevent overload mechanism, including rack applied to index(ing) feed device, lower end, which is arranged, in the rack is rotatablely connected
There are the pawl bar 10 of ratchet 11, the upper end of pawl bar to be hinged with the drive rod 20 of horizontal setting, the middle part setting of the drive rod
There is stopper protrusion 21, the compressed spring 22 that front end acts in stopper protrusion is equipped on drive rod, is also equipped on drive rod
The support base 23 abutted against with the rear end of compressed spring is hinged on the support base and is swung by driving mechanism driving for driving
The former lever 30 of drive rod transverse shifting is hinged with lower end and the matched pawl 12 of ratchet in the middle part of the pawl bar, described
The upper end of pawl is fixed with the connecting rod 40 being laterally arranged, and the rear end of the connecting rod is provided with lobe plate 41, the lobe plate
On be provided with inverted L shape sliding slot 42, be fixed in the original lever with the matched axis pin 31 of L-type sliding slot, be located in the rack
It is provided with sliding pin 51 on rear side of lobe plate, the microswitch being connected with the power supply of driving mechanism is provided on rear side of the sliding pin
52, after being overloaded by ratchet, is moved after driving lobe plate by axis pin and sliding pin is driven to trigger microswitch, make driving mechanism
Power supply disconnects, to make whole device avoid damaging because of overload.
In the present embodiment, the lower end of the pawl bar is rotatably connected to ratchet shaft 13, and the ratchet is installed on ratchet shaft,
The front end of the drive rod is provided with the hinged seat 24 being hinged with pawl bar upper end, and the rear end of drive rod is threaded portion 25,
It is bolted with adjusting nut 26 on the threaded portion, the position of support base is adjusted by adjusting the position of adjusting nut, and then adjust
Save the stroke of drive rod transverse shifting.
In the present embodiment, the upper end of the original lever and the side wall of support base are hinged, and then preferably drive support base.
In the present embodiment, the front end of the connecting rod is provided with the connecting seat 43 being fixedly connected with pawl upper end, described convex
The rear end bolt of wheel plate and connecting rod, preferably to complete to assemble.
In the present embodiment, the inverted L shape sliding slot is by "-" type translot and the sinking portion group for being set to "-" type translot front
At after being overloaded so as to ratchet, ratchet drives pawl to be upwarped with the back-end realization of connecting rod, and then axis pin is made to fall into sinking recess portion
It is interior, and under the action of former lever restoring force with connecting rod after move and make pawl be detached from ratchet.
Operation principle：By pawl driving pawl, when ratchet bears centainly to overload, pawl bar is obstructed without moving, and original is dynamic
Bar is just fromed right to left while compressed spring under the action of driving mechanism to be moved, and the axis pin in former lever is also in lobe plate
It is moved from right to left in notch, since pawl is by the active force of ratchet so that the rear end of connecting rod has the active force upwarped,
So that axis pin drops into the sinking portion of inverted L shape sliding slot, and being combined with L-type sliding slot sinking portion's step.Then, in former lever
When return movement, lobe plate and connecting rod moves right under the action of axis pin and backstroke will walk a distance more, and make
Pawl is disengaged with ratchet.Meanwhile the rear end of lobe plate pushes sliding pin to press microswitch, cutting off the power makes the motor of driving mechanism
Stalling, to make whole device avoid damaging because of overload.
A kind of assembly method for preventing overload mechanism applied to index(ing) feed device includes the following steps：
1）The ratchet bar lower rotational that ratchet shaft equipped with ratchet is hinged with to hinged seat with upper end is connect；
2）It by drive rod and hinged seat bolt and completes to lock, compressed spring is nested on drive rod, and will be hinged with former dynamic
The support base of bar is nested with to be caught up in driving, while adjusting the position of adjusting nut；
3）It by the front end of connecting rod and the connecting seat bolt for being fixed with pawl and completes to lock, and by lobe plate and connecting rod
It completes to be spirally connected in rear end；
4）The inverted L shape sliding slot of lobe plate and the axis pin in former lever are completed to coordinate, and pawl and pawl bar are hinged, is made
It completes to coordinate with ratchet in the lower end of pawl；
5）Sliding pin and microswitch are installed in the rear side of lobe plate.
The foregoing is merely presently preferred embodiments of the present invention, for the ordinary skill in the art, according to this hair
Various forms of labor for preventing overload mechanism from not needing to creativeness applied to index(ing) feed device are designed in bright introduction
It is dynamic, without departing from the principles and spirit of the present invention all equivalent changes done according to scope of the present invention patent, repair
Change, replace and modification, should all belong to the covering scope of the present invention.
