These belong to the scope of protection of the utility model.
Embodiment
A kind of automobile-used towing pin anti-fatigue test detection device, structure as shown in Figure 1, the device be split structure,
By being correspondingly arranged, two frame-type components on the chassis and bulb that are separately connected towing pin 15 are constituted.
Wherein, the frame-type component on connection towing pin chassis is short frame component, including short frame bottom plate 3 and is connected to short frame bottom plate
Short frame foreboard 1, short frame back plate 2 on 3 and connecting lateral plate 4, centre form the space that card sets towing pin chassis.Short frame back plate 2 exists
During carrying out tensile fatigue test, play the role of blocking towing pin chassis, for offsetting pulling force, in short frame back plate 2
Lateral surface is equipped with short frame triangle pulling plate 5, is directly connected to puller system, puller system direct pull triangle pulling plate.Short frame foreboard 1 with
The upper end both sides of short frame back plate 2 are equipped with short frame and shake hands 6, which is set in parallel with connecting lateral plate 4, facilitate the carrying of worker with
Dismounting.Short frame foreboard 1 is equipped with two pieces, is connect respectively with the connecting lateral plate of both sides 4, is formed for towing pin between two short frame foreboards 1
By channel.
The frame-type component for connecting towing pin bulb is long frame component, including long frame bottom plate 11 and is connected on long frame bottom plate 11
Long frame back plate 10, bending side plate 12, setting at top, the cover board 9 that both ends are separately connected with two blocks of bending side plates 12, intermediate shape
Positioning ball 7 is equipped in the space of Cheng Kashe towing pin bulbs.The lateral surface of long frame back plate 10 is equipped with long frame triangle pulling plate 13, should
Triangle pulling plate is then fixed on nose end on the bench vice on horizontal pulling force machine worktable.The top of bending side plate 12 is formed with side wall
90 ° of bending part, the position guarantee that the knob that long frame is shaken hands on 14, with short frame component is connected on the bending part is consistent,
On same straight line.Screw in compression workpiece is also installed with by soket head cap screw 8 on cover board 9, prevents towing pin from turning over.
Position the bulb of snapping towing pin on ball 7, it is ensured that the contact area with the bulb at least 60% of detection device.It will
Towing pin bulb part is buckled on 7 positioning balls, is the reference for installation that towing pin blank does testing fatigue, and the finished product zero simulated
The assembled state of part under usual use conditions is also used for the tensile strength of detection bulb.
Towing pin is due to the use of on automobile (being mostly tractor), for being related to material, installation dimensions etc.
It is required that especially stringent, this experiment is exactly to ensure the safety of towing pin product in use.
In the damage parameters that client is supplied to our company, client, which can do by myself, directly to be simulated using product.I.e. at 30 tons
Pulling force under, it is desirable that apply pulling force stretching and drawing bolt product and do not deform at least 30000 times, for towing pin in reality
Real motion done in the use of border, this experiment substantially once drill true simulation, can sufficiently accurately judge product
Whether mechanical property disclosure satisfy that (stretching experiment of coupon may not be able to reflect to entirely accurate after all for the requirement of client
The mechanical property of towing pin itself ontology).
Although the utility model has the segmented installation in view of the device on puller system lighter, detach in this way
The detection device of formula is individually operated compared with worker is gently facilitated, but main purpose, which is still only this clamping just, can play pair
The effect (can not obviously be used if detection device one) that towing pin ontology stretches.Since puller system does not act on directly directly
(tension) on the body, may lose a tractive force (because bulb part can not take up), our company can slightly add
Big some pulling force, avoid pulling force not up to standard.The specific location of the our company device can be marked for the sake of convenient on puller system, such as
This one can be mounted directly and put.
Split type fatigue test detecting device is divided into length two-part, and for short frame for placing towing pin chassis, there are enough
Gap is put into (there are about 1~2mm in gap), and bulb means suitable sinks to bottom completely, the contact area with positioning ball at least 60%,
Otherwise it is easy stress to tilt, head is caused to dig danger.
Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office
It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims,
This has no effect on the substantive content of the utility model.
