Description

Technical Field

[0001] The present application relates to the technical field of paint film detection tools, and in particular to a paint film strength impact tester. Background Art

[0002] Paint film refers to the brown or black thin layer of paint-like deposits produced by oxidation and polymerization of organic components of fuel and lubricating oil or bearing materials in high temperature and air during lubrication. At present, the domestic experimental method for the impact resistance of paint film generally adopts GB / T1732-1993 Paint Film Impact Resistance Determination Method. This standard stipulates the test method for the impact resistance of paint film expressed by the maximum height at which a fixed-mass hammer falls on the test plate without causing damage to the paint film. In the process of testing the strength of the paint film, a paint film strength impact tester is usually required.

[0003] For example, a Chinese patent (CN203432861U) discloses a paint film high-strength multi-point impact tester, which includes a base, a tower vertically fixed to the base, and a tower bracket for fixing the tower. A test plate is installed between the base and the tower, a test plate fixing beam is installed on the base, and a number of fixing bolts that can rotate up and down are installed on the test plate fixing beam; a heavy hammer with a punch is installed inside the tower, a heavy hammer push rod is provided on the heavy hammer, a concave groove that can move the heavy hammer push rod up and down is opened on the tower body, a positioning scale and a heavy hammer controller are provided on the tower body, and an impact point mask is installed on the surface of the test plate.

[0004] The above scheme also has the following technical defects: the above scheme is not convenient for changing the detection position of the paint film. Since the staff needs to fix the paint film when testing the paint film, so as to avoid the paint film from unloading force when it is hit by a heavy hammer, this results in the paint film needing to be re-fixed every time the detection point is changed, and the operation is very cumbersome. Based on this, a paint film strength impact tester is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a paint film strength impact tester, which has the advantages of convenient replacement of paint film detection points, thereby solving the problem that paint film detection points are inconvenient to replace.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: A paint film strength impact tester, comprising a base, four vertical rods fixed to the top of the base, a horizontal plate fixed to the top of the vertical rods, a testing mechanism installed on the top of the horizontal plate, a position adjustment mechanism installed on the top of the base, a clamping mechanism installed on the adjustment mechanism, and a heavy hammer placed on the testing mechanism;

[0007] The position adjustment mechanism comprises an installation box, a driving assembly installed on the installation box, a moving assembly installed on the driving assembly, and fixing rods fixed to the front and rear ends of the inner wall of the installation box.

[0008] By adopting the above technical solution, the paint film can be driven to change the detection position through the position adjustment mechanism.

[0009] Furthermore, the testing mechanism includes an adjusting assembly installed on the transverse plate and a supporting assembly installed on the transverse plate.

[0010] By adopting the above technical solution, the heavy hammer can be supported, thereby facilitating the detection of the paint film.

[0011] Furthermore, the clamping mechanism includes a first fixing plate mounted on the position adjustment mechanism, a first screw rotatably connected to the inside of the first fixing plate, a first handle fixed to the top end of the first screw and a clamping plate rotatably connected to the bottom end of the first screw.

[0012] By adopting the above technical solution, the paint film can be clamped by the clamping mechanism to prevent the paint film from moving due to impact and causing unloading.

[0013] Furthermore, the driving assembly includes a motor fixed to the front end of the mounting box and a screw fixed to the output shaft of the motor.

[0014] By adopting the above technical solution, the motor can drive the screw rod to rotate.

[0015] Furthermore, the moving assembly includes two moving plates threadedly connected to the outer surface of the screw rod, a connecting rod fixed to the top of the moving plate, and a placement plate fixed to the top of the connecting rod.

[0016] By adopting the above technical solution, the paint film can be supported by the placement plate 5 and driven to move at the same time.

[0017] Furthermore, the adjustment assembly includes a second fixing plate fixed to the top end of the transverse plate, a second screw rod threadedly connected to the inside of the second fixing plate, and a second handle fixed to one end of the second screw rod.

[0018] The above technical solution can drive the support plate to move.

[0019] Furthermore, the support assembly includes a support plate rotatably connected to an end of the second screw rod away from the second handle and a sliding block fixed to the bottom end of the support plate.

[0020] The above technical solution is adopted to facilitate the heavy hammer to fall from the middle after the two support plates are separated.

[0021] Furthermore, the top end of the placement plate is fixed to the bottom end of the first fixed plate, and the movable plate slides on the outer surface of the fixed rod.

[0022] By adopting the above technical solution, the paint film is clamped by cooperating between the placement plate and the clamping mechanism.

[0023] Furthermore, a placement groove is provided at the top of the support plate, and a sliding groove is provided at the top of the cross plate, and the sliding block slides in the sliding groove.

[0024] The adoption of the technical solution facilitates the sliding of the support plate.

[0025] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0026] 1. The paint film strength impact tester is provided with a position adjustment mechanism and a clamping mechanism at the top of the base, so that the paint film can be clamped once and multiple points can be tested at the same time. There is no need to re-fix the paint film after testing one point, thereby improving the detection efficiency of the paint film.

[0027] 2. The paint film strength impact tester is equipped with a detection mechanism at the top of the horizontal plate, which can support the heavy hammer before it falls, and let the heavy hammer fall from the middle when it is needed to fall, so as to facilitate the detection of the paint film.
