[0026] The utility model is further described below in conjunction with the accompanying drawings:

[0027] like Figure 1-Figure 8 As shown, an impact resistance testing device for ship sealing rubber parts comprises a base 1, a bracket 101 is fixedly connected to the top of the base 1, an impact detection mechanism 2 is arranged on the bracket 101, the impact detection mechanism 2 comprises an impact rod 201, guide rods 202 are welded on both sides of the impact rod 201, the guide rod 202 is slidably connected to the bracket 101 along the vertical direction, a top plate 203 is connected to the top of the guide rod 202 by screws, a pressure-bearing inclined block 204 is welded to the bottom of the top plate 203, an elastic mechanism 3 for driving the guide rod 202 to impact downward is arranged on the bracket 101, and a pressure-bearing inclined block 204 is welded to the bottom of the top plate 203. A power mechanism 4 for moving upward 204, a support platform 102 is fixedly connected to the top of the bracket 101, a pressure sensor 103 is arranged in the support platform 102, and the pressure sensor 103 is located directly below the impact rod 201. Through the cooperation of the elastic mechanism 3 and the power mechanism 4, the impact rod 201 can be reciprocated up and down, and the impact rod 201 impacts the rubber part downward to achieve an impact resistance test. The pressure sensor 103 detects the impact force, and a clamping mechanism 5 is arranged on the top of the base 1. The clamping mechanism 5 is located on both sides of the support platform 102, and a tensile detection mechanism 6 for driving the clamping mechanism 5 to move is arranged on the top of the base 1.

[0028] The elastic mechanism 3 includes a U-shaped frame 301, which is connected to the bracket 101 by screws. A sliding rod 302 is slidably connected to the U-shaped frame 301 in the vertical direction, and a spring 303 is fixedly connected to the bottom end of the sliding rod 302. The interior of the impact rod 201 is hollow, and the sliding rod 302 is slidably inserted into the impact rod 201 from above. The bottom end of the spring 303 is fixedly connected to the inner bottom wall of the impact rod 201. When the impact rod 201 moves upward, the spring 303 is compressed. When the impact rod 201 is no longer subjected to the upward force, the spring 303 rebounds quickly to make the impact rod 201 impact downward. The sliding rod 302 is hollow, and an adjusting screw rod 304 is connected to the internal thread of the sliding rod 302. The top end of the adjusting screw rod 304 is rotatably connected to the bracket 101. When the adjusting screw rod 304 is rotated, the sliding rod 302 is driven to move up and down, thereby adjusting the initial compression amount of the spring 303 to adjust the force when the spring 303 drives the impact rod 201 to impact downward.

[0029] The power mechanism 4 includes a motor 401, which is fixedly connected to the bracket 101. The output shaft of the motor 401 is fixedly connected to a rotating block 402.

The extrusion inclined blocks 403 can contact the pressure-bearing inclined block 204. The motor 401 drives the rotating block 402 to rotate, and the rotating block 402 drives the extrusion inclined block 403 to rotate. After the extrusion inclined block 403 contacts the pressure-bearing inclined block 204, the extrusion inclined block 403 squeezes the pressure-bearing inclined block 204 upward. When the extrusion inclined block 403 loses contact with the pressure-bearing inclined block 204, the spring 303 drives the impact rod 201 to move downward, so that the guide rod 202, the top plate 203 and the pressure-bearing inclined block 204 move downward and reset.

[0030] The clamping mechanism 5 includes two movable frames 501 that are symmetrically arranged on the left and right. The movable frames 501 are slidably connected to the top of the base 1. The movable frame 501 is a rectangular frame. The top wall of the movable frame 501 is connected to a clamping screw rod 502 through an internal thread. The clamping screw rod 502 passes through the top wall of the movable frame 501 from top to bottom. The bottom of the clamping screw rod 502 is rotatably connected to a clamping plate 503. The clamping plate 503 is slidably connected to the front and rear walls of the movable frame 501. When the clamping screw rod 502 rotates, it moves up and down, thereby driving the clamping plate 503 to move up and down, thereby clamping and releasing the rubber part.

[0031] The stretching detection mechanism 6 includes two electric push rods 601 symmetrically arranged on the left and right. The electric push rods 601 are connected to the top of the base 1 by screws. The output end of the electric push rod 601 is fixedly connected to a mounting block 602. The mounting block 602 is fixedly connected to a tension sensor 603 on one side close to the movable frame 501. The tension sensor 603 is fixedly connected to the movable frame 501. When the clamp 503 clamps the rubber part, the movable frame 501 is moved by the extension and retraction of the electric push rod 601 to stretch the rubber part, so that the tensile strength of the rubber part can be tested. The tensile stress condition of the rubber part is detected by the tension sensor 603. The bottom of the clamp 503 and the inner bottom wall of the movable frame 501 are both provided with anti-slip grooves to improve the stability of the rubber part clamping.

[0032] Working principle: When in use, place the rubber piece on the carrier 102, place the two ends of the rubber piece under the clamping plate 503, twist the clamping screw 502, the clamping screw 502 drives the clamping plate 503 to move down to clamp the rubber piece, and the electric push rod 601 drives the movable frame 501 to move so as to pull the two ends of the rubber piece to keep the rubber piece flat, and then the motor 401 drives the rotating block 402 to rotate, the rotating block 402 drives the extrusion inclined block 403 to rotate, after the extrusion inclined block 403 contacts the pressure inclined block 204, the extrusion inclined block 403 squeezes the pressure inclined block 204 upward, the pressure inclined block 204 drives the top plate 203 to move up, the top plate 203 drives the guide rod 202 to move up, the guide rod 202 drives the impact rod 201 to move up, the impact rod 201 will The spring 303 is compressed. When the extrusion bevel block 403 is out of contact with the pressure bevel block 204, the spring 303 drives the impact rod 201 to move downward. The impact rod 201 impacts the rubber part. The pressure sensor 103 detects the impact force and comprehensively judges the impact resistance by checking the appearance of the rubber part. When the impact force of the impact rod 201 needs to be adjusted, the adjusting screw rod 304 is rotated. The adjusting screw rod 304 drives the sliding rod 302 to move up and down, thereby adjusting the initial compression of the spring 303. Since the distance that the impact rod 201 moves up each time is fixed, when the initial compression of the spring 303 increases, the force applied by the spring 303 to the impact rod 201 is also greater, thereby increasing the impact force of the impact rod 201, and vice versa. The impact force of the impact rod 201 is reduced.

[0033] The two movable frames 501 are driven to move away from each other by the two electric push rods 601, so that the rubber member is stretched, and the tension sensor 603 detects the stretching force to test the tensile strength of the rubber member.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
