Specific embodiment
The optimal technical scheme that according to the present invention will be described in detail below with reference to the accompanying drawings.
A kind of oblique friction impact test instrument of paint film of the utility model, including bottom plate 1, guide rail 2, coaster 3, slide bar 4,
The center of gravity rod 5, the bottom plate 1 offers through-hole, and the two sides of the through-hole are respectively arranged with a guide rail 2, and guide rail 2 is in
Oblique placement, lower one end are provided with support rod 6 close to 1 surface of bottom plate of through-hole between higher end and bottom plate 1, two are led
Rail 2 is located on the same line under overlooking state, and the length of guide rail 2 is 50cm-150cm, the folder between guide rail 2 and bottom plate 1
Angle is 30 ° -60 °, and the section of the guide rail 2 is the U-shaped structure of opening upwards；
The coaster 3 is arranged on the edge of guide rail 2, and coaster 3 is on two ends of U-shaped structure along 2 length side of guide rail
To activity；
The slide bar 4 is horizontal to be located at two 2 tops of guide rail, has slide 7 on slide bar 4, is provided perpendicular to through slide 7
The through-hole on ground, the gravity rod 5 is vertical to be set to 3 top of coaster, and coaster 3,5 lower end of gravity rod are run through in the lower end of gravity rod 5
Portion edge is provided with a pair of of pin shaft, and pin shaft rotary spacing makes 3 relative gravity bar of coaster, 5 lower end that angle occur inclined on coaster 3
Turn, for pin shaft perpendicular to the direction of advance of coaster 3, which is additionally provided with impact head 10, and the upper end setting of the gravity rod 5 is limited
Position bar 8, gag lever post 8 run through the through-hole for being active in slide 7, and gag lever post 8 can move in through-hole, guarantee gravity rod 5 always with vertical
The state of formula carries out the activity in horizontal direction；
Two guide rails 2 are provided with the conducting bar 9 of two arcs between the end of bottom plate 1, between two conducting bars 9 with bottom plate
1 through-hole be it is common, the conducting bar 9 is made of toughness material, and the coaster 3 is moved along guide rail 2 and conducting bar 9, the conducting bar 9 away from
It is less than the length of impact head 10 with a distance from shock-testing plate.
In use, coaster 3 to be first moved to the highest point of a side rails 2, slide 7 also is located at one end of slide bar 4 at this time, loses
Coaster 3 is opened, under the influence of gravity, gravity rod 5 accelerates to move with fly block 3 to 2 minimum point of guide rail, exists by gag lever post 8
Activity in 7 through-hole of slide, gravity rod 5 also drive slide 7 movable on slide bar 4, keep itself being always vertical state simultaneously,
When coaster slides on conducting bar 9, and the movable minimum point of entire gravity rod 5, impact force is maximum at this time, and impact head 10 is direct
The plate of paint film is coated with from oblique shock, due to inertia, coaster 3 will continue to previous (i.e. another side rails 2) activity, thus from another
The minimum point of one side rails 2 is slowed down to the side highest point to be moved, and impact head 10 is detached from rapidly after the completion of primary hit hits model
It encloses, then fixes coaster 3, wait use next time, finally the plate of primary oblique shock is assessed.
Further, the coaster 3 is divided into front vehicle body 11, buffer body 12, aftercarriage 13, and the two of the front vehicle body 11
Side and the two sides of aftercarriage 13 are provided with idler wheel 14, and the idler wheel 14 rolls on the edge of guide rail 2, the front vehicle body 11
The front and rear part of buffer body 12 is respectively hinged at aftercarriage 13, buffer body 12,5 lower end of gravity rod are passed through in the lower end of the gravity rod 5
A pair of of pin shaft rotary spacing in portion can hit plate to avoid impact head 10 because length is too long in this way on buffer body 12
Afterwards, the problem of reaction force props up the problem of coaster 3, can also be detached from guide rail 2 to avoid coaster 3, makes impact head 10 after shock,
Reaction force acts are on buffer body 12, and buffer body 12 is propped up, and front vehicle body 11 and aftercarriage 13 are still contacted in guide rail 2
On.
Further, front vehicle body 11 and 13 direction of aftercarriage are respectively facing on buffer body 12 and is extended block
16, prevent that the level height of buffer body 12 is equivalent to front vehicle body 11 and aftercarriage 13 is too low, block 16 is located at table on buffer body 12
Face does not influence buffer body 12 relative to front vehicle body 11 and aftercarriage 13 and is raised above movement.
Further, groove body 15 is offered on the circumferencial direction of the idler wheel 14, the edge of the guide rail 2 is located at slot
In body 15, clearance fit between groove body 15 and guide rail 2 ensure that idler wheel 14 without departing from the edge of guide rail 2 significantly；
The support rod 6 is telescopic, correspondingly, guide rail 2 is just mutually cut with scissors with bottom plate 1 close to one end of 1 through-hole of bottom plate
It connects, the length for adjusting support rod 6 can adjust the angle between guide rail 2 and bottom plate 1, and 6 length of support rod is longer, and coaster 3 exists
Potential energy on guide rail 2 is bigger, and the impact force and frictional force of opposite gliding speed and impact head 10 are bigger, is suitble to different shocks
The test of power is adjusted.
