Description
Technical Field
The utility model relates to the field of machining, in particular to a protection device for a swinging rotating shaft.
Background
The hard box packaging machine conveying wheel lifter rotates through the driving shaft, the swing arm drives the sliding block to reciprocate, lifting of the tobacco package is completed, when equipment is in a truck or suddenly stopped due to other reasons, the tobacco package transmission part does not stop moving immediately, and can continue to move forward for a plurality of stations, so that the equipment truck is caused, the components such as a tobacco package box mould, an upper ring and a lower ring are blocked, the equipment safety problem is caused, and meanwhile, when the equipment is in the truck due to the reasons such as tobacco package blockage, the transmission stress inside the tobacco package conveying wheel exceeds the maximum bearing value, so that the position of the transmission part inside the tobacco package conveying wheel is in a stringing manner.
Disclosure of utility model
In order to solve the problems, the utility model discloses an overload protection device for a lifting rod.
The specific technical scheme is as follows:
The utility model provides a lifting rod overload protection device, sets up a base, sets up a through-hole on the base, one side of through-hole sets up the shell fragment, and the middle part of base sets up work notch, set up the swing arm in the work notch, the connecting pin wears to locate the through-hole and rotates swing arm and base to link together, set up a constant head tank on the swing arm, the constant head tank corresponds in work notch department and sets up the ball, the ball still with the tip butt of shell fragment, the ball sets up in the base.
The elastic sheet is provided with a waist hole, and the elastic sheet and the base are fixed together by a fixing pin penetrating through the elastic sheet.
The end rounding of base sets up.
The base is provided with a rotating shaft hole, one side of the rotating shaft hole is provided with a notch, a threaded through hole is formed above the notch, and the fixing bolt is in threaded connection with the threaded through hole.
The swing arm is T-shaped.
And a proximity switch is arranged on the base.
The utility model has the advantages that: when the equipment is blocked by external force on the running of the equipment in the transmission process of the equipment, the swing arm can be instantaneously separated from the base without being blocked by balls, so that the equipment transmission system is protected and the equipment is stopped rapidly, the equipment can be widely applied to various mechanical equipment, and can also be widely applied to a plurality of parts of other packing machines in a rolling and packing workshop, which have potential safety hazards of the equipment.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a schematic perspective view of the present utility model;
Fig. 3 is a schematic structural view of the overload protection device for the bidirectional lifting rod.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model provides a lifting rod overload protection device, sets up a base 1, sets up a through-hole 2 on the base 1, one side of through-hole 2 sets up shell fragment 3, and the middle part of base 1 sets up work notch 4, set up swing arm 5 in the work notch 4, connecting pin 6 wear to locate through-hole 2 with swing arm 5 and base 1 rotate to link together, set up a constant head tank 51 on the swing arm 5, constant head tank 51 corresponds in work notch 4 departments and sets up ball 6, ball 6 still with the tip butt of shell fragment 3, ball 6 sets up in base 1.
The elastic sheet 3 is provided with a waist hole 7, and a fixing pin 8 penetrates through the elastic sheet 3 to fix the elastic sheet 3 and the base 1 together.
The end part of the base 1 is provided with a round angle
The base 1 is provided with a rotating shaft hole 9, one side of the rotating shaft hole 9 is provided with a notch 91, a threaded through hole is formed above the notch 91, and the fixing bolt 10 is screwed in the threaded through hole.
The swing arm 5 is T-shaped.
The base 1 is provided with a proximity switch 11.
The utility model further discloses a bidirectional lifting rod overload protection device, the structure of which is identical to that of the lifting rod overload protection device, and the difference is that the end part of the base 1 is provided with round corners at the upper and lower parts, and a working notch penetrates through the base to form a working notch 12.
The working principle of the utility model is as follows: during normal operation, the pivot hole on the base is connected with the pivot and is used as the power supply, drive the base and swing, because swing arm and base pass through ball connection make the swing arm also swing, when equipment receives the katon, the tip of swing arm can receive the impact force, this impact force can take off the swing arm ball to make the swing arm produce the rotation around the swivel pin, therefore base tip even still is working, also can not produce further influence to subsequent work, because set up proximity switch on the base, when making take place the displacement between swing arm and the base, proximity switch will produce the physical signal conversion of displacement and give the controller of signal transmission, the controller is shut down the machine after obtaining the signal and is guaranteed that whole transmission system is in time shut down.
