Description

Technical Field

[0001] The present application relates to the field of test tooling, and more particularly to an impact test tooling. Background Art

[0002] The film impact test is generally applicable to detecting the impact resistance of dry film coatings (such as paint or varnish, etc.); during the standard test process, the dry film coating is deformed by the impact of a sphere, thereby resisting the impact force; if the deformation is too large, the dry film coating will peel or crack, which can also reflect the adhesion of the dry film coating.

[0003] Publication No. CN 218956307 U discloses a film impact test tooling. The telescopic assembly can be used to adjust the distance of the ball hammer fixedly connected below the telescopic rod, and the driving mechanism can be used to adjust the clamping plate to clamp the substrate. When it is necessary to increase the weight of the weight hammer, only a weight block needs to be added to the weight rod, and there is no need to replace the entire hammer body, meeting the impact test requirements of different substrates. When reducing the weight, the bolts connecting the two arc-shaped blocks can be disassembled, and there is no need to replace the entire ball hammer to increase the weight.

[0004] However, there are some defects in the above solution: in the above solution, the weight block is installed by the connection method of bolts and nuts, and the disassembly and assembly by the connection method of bolts and nuts are relatively slow. When multiple weight blocks need to be disassembled, the disassembly and assembly efficiency is more affected. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0032] Please refer to Figures 1 - 5 , the present application provides an impact test tooling including a clamping assembly 100 and an impact assembly 200.

[0033] Please refer to Figure 1 and 2 , the clamping assembly 100 includes a bottom plate 110, a driving member 120 and a clamping plate 130. The driving member 120 is disposed on the top of the bottom plate 110, and the clamping plate 130 is disposed on one side of the driving member 120.

[0034] Among them, the driving member 120 includes a groove plate 121, a bidirectional lead screw 122 and a motor 123. The groove plate 121 is fixedly connected to the bottom plate 110. The bidirectional lead screw 122 is rotatably disposed in the groove plate 121. The motor 123 is installed on the top of the groove plate 121 and is drivingly connected to the bidirectional lead screw 122. The clamping plate 130 is threadedly sleeved on the clamping plate 130. By setting the groove plate 121, the bidirectional lead screw 122 and the motor 123, starting the motor 123, the motor 123 drives the bidirectional lead screw 122 to rotate, and the bidirectional lead screw 122 drives the two clamping plates 130 to move, adjusting the distance between the two clamping plates 130 to adapt to different specifications of the bottom substrate plate.

[0035] In a specific implementation, the clamping plate 130 and the inner wall of the groove plate 121 are in clearance fit. The clamping plate 130 is provided with a groove. By setting the clearance fit between the clamping plate 130 and the inner wall of the groove plate 121, it is used to limit the rotation during the screw drive and guide its linear movement.

[0036] Specifically, a positioning bolt 131 is threadedly penetrated through the clamping plate 130, and the positioning bolt 131 abuts against the bottom substrate plate. By setting the positioning bolt 131 to threadedly penetrate through the clamping plate 130, the bottom substrate plate placed in the groove of the clamping plate 130 is pressed tightly.

[0037] Please refer to Figure 1 , 2 , 3, 4 and 5, the impact assembly 200 includes a vertical plate 210, a rotating member 220, a connecting rod 230, a disc 240, a counterweight 250, a limiting rod 260 and a limiting knob 270. The vertical plate 210 is disposed on the top of the bottom plate 110. The rotating member 220 is disposed on one side of the vertical plate 210. The connecting rod 230 is disposed at the bottom of the rotating member 220. The disc 240 is fixedly connected to the connecting rod 230. The counterweight 250 is inserted on the surface of the connecting rod 230. One end of the limiting rod 260 is rotatably connected to the disc 240 and is clamped to the counterweight 250. The limiting knob 270 is threadedly penetrated through the limiting rod 260 and the connecting rod 230.

[0038] Among them, the rotating member 220 includes a rotating shaft 221, a fixed tube 222, a sliding rod 223 and a positioning knob 224. The rotating shaft 221 rotates through the vertical plate 210. The fixed tube 222 is fixedly connected to the rotating shaft 221. The sliding rod 223 is slidably arranged in the fixed tube 222. The positioning knob 224 is threaded through the fixed tube 222 and the sliding rod 223. By providing the rotating shaft 221, the fixed tube 222, the sliding rod 223 and the positioning knob 224, the sliding rod 223 slides and adjusts its position in the fixed tube 222, and then is positioned and fixed by the positioning knob 224, so as to adjust its overall length.

[0039] In this embodiment, the counterweight 250 is provided with a card slot 252, and the limiting rod 260 is adapted to the card slot 252. By providing that the limiting rod 260 is adapted to the card slot 252, it is used to limit and connect the counterweight 250.

[0040] Specifically, the limiting rod 260 and the connecting rod 230 are both provided with a plurality of positioning threaded holes 280. The limiting knob 270 is threadedly connected to the positioning threaded holes 280. By providing a plurality of positioning threaded holes 280, according to the number of added or removed counterweights 250, the limiting knob 270 is screwed into the corresponding positioning threaded holes 280, so as to fix the counterweight 250.

[0041] In a specific implementation scheme, a scale disk 211 is provided on one side of the vertical plate 210. The rotating shaft 221 rotates through the scale disk 211. By providing the scale disk 211, it is used to record the rotation angle of the calibration ball hammer. After rotating to different angles, the impact force of the ball hammer on the base material will also be different.

[0042] The working principle of this impact test tooling: During use, when it is necessary to disassemble and assemble the splash counterweight 250, first rotate and remove the limiting knob 270, rotate the limiting rod 260, so that the limiting rod 260 rotates and falls away from the counterweight 250, then the counterweight 250 can be taken and placed from the disk 240 and the connecting rod 230, and multiple quick take and place operations can be carried out. Then rotate the limiting rod 260 back so that the limiting rod 260 rotates and stands up, and the limiting rod 260 is stuck into the card slot 252 to realize the limitation of the counterweight 250. Finally, according to the number of added or removed counterweights 250, the limiting knob 270 is screwed into the corresponding positioning threaded holes 280, so as to fix the counterweight 250, thus facilitating the quick disassembly and assembly of multiple counterweights 250 and improving the disassembly and assembly efficiency.

[0043] It should be noted that the specific model and specification of the motor 123 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail here.

[0044] The power supply and principle of the motor 123 are clear to those skilled in the art, and will not be described in detail here.
