Description
Technical field
The present invention relates to a kind of impact test instrument, the oblique friction impact test instrument of especially a kind of paint film belongs to paint film
Exerciser technical field.
Background technology
Paint film shock machine layer impact resistance experiment, which is applicable in, examines evaluation colored paint, and the dry film coating of varnish or Related product is being marked
Its coating resists the ability peeled off or cracked from ground, table when being deformed by the impact of different spheres under the conditions of quasi-experiment
Show by the epistasis of experiment coating and to the adhesive force of ground；The impact resistance of paint film mainly passes through paint in coating industry at present
Film impact tester measures, and is used as with the maximum height that the weight of fixed mass is fallen on test plate (panel) without causing paint film to destroy
Impact-resistant performance indicator, paint film impact strength are to evaluate one of the important indicator of painting quality.
And in existing paint film impactor test process, impact test only often is carried out in test plate (panel) vertical direction, and it is true
Shock be then all directions for being happened at plank in most cases, if plank when oblique direction is by impact force, not only
The problem of the problem of being impact dynamics, also frictional force, when frictional force and impact force collective effect are in plank, paint film coating is just
It is followed by impacted in tearing for frictional force, if paint film has weakened its intensity or adhesiveness after by friction force effect,
In the case of impact force then, the problem of being easy for cracking and flaking off.
Application No. is 201621216032.6 Chinese patents to disclose a kind of paint paint film impact test instrument, including height

Seat connection, the base upper surface are sequentially installed with level detection device, objective table and fixed seat from front to back, and under pedestal
Side is uniformly equipped with Level tune foot-screw.Although the utility model can make punch be impacted in different positions
Experiment, simulation different angle obtains relatively accurate test result, but activity of the punch in oblique pipe can be by frictional force
It influences, weakens impact force, and since punch weight is larger, after oblique impact plank, it may occur that micro- bullet and then secondary whereabouts
Plank is impacted, and true impact process usually just flicks after primary hit, therefore secondary pulse can cause plank paint film
Additional damage, to true test result, there is also large effects.

Specific implementation mode
The optimal technical scheme that the invention will now be described in detail with reference to the accompanying drawings.
A kind of oblique friction impact test instrument of paint film of the present invention, including bottom plate 1, guide rail 2, coaster 3, slide bar 4, gravity
The center of bar 5, the bottom plate 1 offers through-hole, and the both sides of the through-hole are respectively set there are one guide rail 2, and guide rail 2 is in oblique
It places, relatively low one end is provided with supporting rod 6 close to 1 surface of bottom plate of through-hole between higher end and bottom plate 1, two guide rails 2 exist
It is located on the same line under vertical view state, the length of guide rail 2 is 50cm-150cm, and the angle between guide rail 2 and bottom plate 1 is
30 ° -60 °, 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 lived in two 2 length directions of end upper edge guide rail of U-shaped structure
It is dynamic；
The slide bar 4 is horizontal to be located at two 2 tops of guide rail, has slide 7 on slide bar 4, ground is provided perpendicular to through slide 7
Through-hole, the gravity rod 5 is vertical to be set to 3 top of coaster, and coaster 3,5 lower end side of gravity rod are run through in the lower end of gravity rod 5
Edge is provided with a pair of of axis pin, and axis pin rotary spacing makes 3 relative gravity bar of coaster, 5 lower end that angular deflection, pin occur on coaster 3
For axis perpendicular to the direction of advance of coaster 3, which is additionally provided with impact head 10, and the upper end of the gravity rod 5 is provided with gag lever post
8, gag lever post 8 runs through the through-hole for being active in slide 7, and gag lever post 8 can move in through-hole, ensures gravity rod 5 always with vertical
State 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, lead to bottom plate 1 between two conducting bars 9
Hole is common, and the conducting bar 9 is made of toughness material, and the coaster 3 is moved along guide rail 2 and conducting bar 9,9 distance of the conducting bar
The distance of shock-testing plate is less than the length of impact head 10.
In use, coaster 3 to be first moved to the peak 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 5 movable minimum point of entire gravity rod, impact force is maximum at this time, and impact head 10 is direct
The plank of paint film is coated with from oblique shock, due to inertia, coaster 3 will continue to previously（That is another side rails 2）Activity, thus from another
The minimum point of one side rails 2 is slowed down to the side peak to be moved, and model is hit in the rapid disengaging after the completion of primary hit of impact head 10
It encloses, then fixes coaster 3, wait for use next time, finally the plank 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 both sides of aftercarriage 13 are both 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 pin axis rotary spacing in portion can hit plank to avoid impact head 10 because length is long in this way on buffer body 12
Afterwards, reaction force props up the problem of coaster 3, can also avoid the problem that coaster 3 is detached from guide rail 2, make 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 12 upper table of buffer body
Face does not influence buffer body 12 and is raised above movement relative to front vehicle body 11 and aftercarriage 13.
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 edge of the idler wheel 14 without departing from guide rail 2 significantly；
The supporting rod 6 is telescopic, correspondingly, guide rail 2 is just hinged with bottom plate 1 close to one end of 1 through-hole of bottom plate, is adjusted
The length of section supporting rod 6 can adjust the angle between guide rail 2 and bottom plate 1, and 6 length of supporting rod is longer, and coaster 3 is in guide rail 2
On potential energy it is bigger, the impact force and frictional force of opposite gliding speed and impact head 10 are bigger, are suitble to different impact forces
Experiment is adjusted.
Above-described specific implementation mode has carried out further the purpose of the present invention, technical solution and advantageous effect
It is described in detail, it should be understood that the foregoing is merely the specific implementation mode of the present invention, is not limited to this hair
Bright, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should be included in the present invention
Protection domain within.
