Description
Technical field
The utility model is related to accessory test equipment field more particularly to a kind of screw head toughness testing devices.
Background technology
In the production technology of screw, to ensure the phenomenon that screw is not in head fracture when in use, it will usually
Impact test is carried out to the toughness of screw head when product testing.Currently, common test method is：On inclined testboard
The screw hole of various specifications is set, and screw is put into testboard hole with holes, then screw is tapped by hand, until
The side of head of screw is contacted with testboard, at this point, checking whether the head of screw has obscission or crackle.This test side
Formula is fairly simple, but since the process for tapping screw is carried out by human hand is dynamic completely, it can be because the process tapped manually be used
Power is uneven, percussion direction is inconsistent, and leading to test result, there are larger deviations.
In existing technology, there is also a kind of equipment by driving elevating lever manually to be tapped to screw, but
It is that this equipment is influenced that still very greatly, the deviation of test result can not be avoided completely by the subjective factor of people.
Utility model content
The purpose of this utility model is that：For in the prior art, in screw head test process, since there are human hand works
It operates, dynamics is tapped in people's manual handling thereof and is differed, therefore test result can have relatively large deviation, this practicality
A kind of novel screw head toughness testing device of offer.
The technical solution adopted in the utility model is as follows：
A kind of screw head toughness testing device, including pedestal and testboard, testboard are fixed on pedestal, pedestal
Upper setting organic frame is fixedly installed lifting tube and gravity drop hammer driving structure in rack；It is arranged with lifting structure in lifting tube, rises
The bottom end for dropping structure connects gravity drop hammer, and the top of lifting structure connects gravity drop hammer driving structure.
Further, gravity drop hammer driving structure is a brace and connecting rod framework.
Further, the gravity drop hammer driving structure includes a driving wheel, and an end face of driving wheel is equipped with connection
Axis, connecting shaft, connecting rod, lifting structure are sequentially connected；Connecting shaft is rotatably connected with connecting rod, connecting rod and the rotatable company of lifting structure
It connects.
Further, lifting structure includes sliding block and the elevating lever that is connected on sliding block；Sliding block is rotatably connected with connecting rod,
Elevating lever is fixedly connected with a slide block.
Further, the driving wheel is rotatably arranged in rack.
Further, the driving wheel and the dynamic connection of machine shaft.
Further, driven gear, driven gear and electricity are fixed on end face opposite with connecting shaft on the driving wheel
The shaft of machine is moved in turn connection by chain.
In conclusion by adopting the above-described technical solution, the utility model has the beneficial effects that：
1. using the screw head toughness testing device of scheme, due in test process, tapping screw using machinery
It carries out, therefore, the dynamics of percussion will not receive influence due to people's manual operations, and percussion dynamics is uniform, therefore, the knot of test
The deviation of fruit is also greatly reduced than manually-operated test equipment.
2. using the screw head toughness testing device of this programme, since the rotating speed of motor can be very high, to screw
Percussion frequency can also greatly improve, to improve testing efficiency.
