At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides a PU foam wheel puncture test device to solve the problem that the existing puncture test usually uses a manual hand-held puncture tool. When the existing puncture test device is used by hand-held puncture tool, it is not only inefficient, but also requires manual removal after puncture, which can easily lead to tearing of the puncture site of the foam wheel and affect the test results. Utility Model Content

[0004] This invention proposes a PU foam wheel puncture test device, which solves the problem that existing puncture tests usually use manual hand-held puncture tools. When puncturing with a manual hand-held puncture tool, the existing puncture test device is not only inefficient, but also requires manual removal after puncture, which can easily lead to tearing of the puncture site of the foam wheel and affect the test results.

[0005] The technical solution of this utility model is implemented as follows: a PU foam wheel puncture test device includes: a support mechanism, and a guide rail mechanism is fixedly connected to the top surface of the support mechanism.

[0006] A moving mechanism is slidably connected to the top of the guide rail mechanism.

[0009] In a preferred embodiment, a slider assembly is fixedly connected to the outer side of the moving mechanism. Two slider assemblies are fixedly connected to the outer side of each moving mechanism in opposite directions. The moving mechanism is slidably connected to the transverse groove opened in the guide rail mechanism through the slider assembly.

[0010] In a preferred embodiment, a leg assembly is fixedly connected to the bottom surface of the support mechanism.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 As shown, a PU foam wheel puncture test device includes: a support mechanism 1, and a guide rail mechanism 2 is fixedly connected to the top surface of the support mechanism 1;

[0026] The top of the guide rail mechanism 2 is slidably connected to the moving mechanism 3. The moving mechanism 3 has a longitudinal groove inside. The moving component 3012 is fixedly connected inside the longitudinal groove. The center of the moving component 3012 is fixedly connected to the base plate component 3013. The base plate component 3013 has a circular structure, and the bottom surface of the base plate component 3013 is fixedly connected to the piercing component 3014. The base plate component 3013 and the piercing component 3014 together form the piercing structure.

[0027] The puncture component 3014 and the base plate component 3013 are vertically arranged, and the outer side of the moving component 3012 is fixedly connected to two protrusions facing each other. The moving component 3 is slidably connected to the moving mechanism 3 through the protrusions. The moving mechanism 3 is fixedly connected to a longitudinally arranged servo push rod 3011 inside. The servo push rod 3011 is connected to the moving component 3012 slidably connected in the moving mechanism 3. The servo push rod 3011 and the moving component 3012 together form a longitudinal displacement structure.

[0028] Among them, the outer side of the moving mechanism 3 is fixedly connected to the slider assembly 301. Two slider assemblies 301 are fixedly connected to the outer side of each moving mechanism 3 in opposite directions. The moving mechanism 3 is slidably connected to the transverse groove opened in the guide rail mechanism 2 through the slider assembly 301. The bottom end face of the support mechanism 1 is fixedly connected to the leg assembly 101. There are two leg assemblies 101 in total, and the two leg assemblies 101 are fixedly connected to the left and right sides of the bottom end face of the support mechanism 1 in a linear array. The support mechanism 1 and the leg assembly 101 together form a support structure.

[0029] The support mechanism 1 has a clamping push rod 1011 fixedly connected to its inner side. The clamping push rod 1011 is arranged horizontally, and there are two clamping push rods 1011. The two clamping push rods 1011 are arranged opposite to each other. The outer sides of the two clamping push rods 1011 are fixedly connected to a sliding component 1013. The inner side of the clamping component 1012 clamps and limits the foaming wheel 1014. The clamping push rod 1011 and the clamping component 1012 together form a clamping and limiting structure for the outer edge of the foaming wheel 1014.

[0030] In use, first place the foaming wheel 1014 to be tested in the designated position inside the support mechanism 1, ensuring that the test area of ​​the foaming wheel faces upward. Operate the two horizontally arranged clamping push rods 1011, and drive the clamping push rods 1011 to move horizontally toward the foaming wheel 1014 by external force. At this time, the sliding component 1013 on the outside of the clamping push rod 1011 slides synchronously under the guidance of the inner wall of the support mechanism 1, ensuring that the clamping process is stable and without shaking.

[0031] After the clamping component 1012 contacts the outer edge of the foaming wheel 1014, the pushing force is continued until the clamping component 1012 is tightly attached to the surface of the foaming wheel. The mechanical clamping force is used to fix the foaming wheel 1014 to prevent it from shifting or rotating during the puncture process. The servo motor 201 on one side of the guide rail mechanism 2 is started. The output shaft of the servo motor 201 drives the transmission screw 2011 to rotate. The transmission screw 2011 and the nut seat at the bottom of the moving mechanism 3 form a helical transmission pair.

[0032] The moving mechanism 3 is embedded in the transverse groove at the top of the guide rail mechanism 2 by the outer slider assembly 301. Driven by the transmission screw 2011, the slider assembly 301 slides horizontally along the transverse groove, thereby driving the entire moving mechanism 3 to move horizontally above the guide rail mechanism 2. Through the precise control of the servo motor 201, the moving mechanism 3 can move horizontally to any test position directly above the foaming wheel 1014, realizing flexible positioning of the puncture point.

[0033] When the moving mechanism 3 is positioned at the target test point, the servo push rod 3011 inside the moving mechanism 3 is triggered to start working. The push rod end of the servo push rod 3011 is fixedly connected to the moving component 3012. The push rod is driven by the motor to move downward in the longitudinal direction. The protrusion on the outside of the moving component 3012 is embedded in the longitudinal groove of the moving mechanism 3. Under the push of the servo push rod 3011, the moving component 3012 descends vertically along the longitudinal groove, driving the bottom plate component 3013 and the puncture component 3014 to move downward synchronously. The puncture component 3014 is vertically connected to the bottom plate component 3013. When the puncture component 3014 contacts the surface of the foaming wheel 1014, the servo push rod 3011 continues to apply a stable pushing force, so that the puncture component 3014 gradually pierces into the inside of the foaming wheel until the preset puncture depth is reached or the puncture test is completed.

[0034] After the puncture is completed, the servo push rod 3011 moves in the opposite direction, and the push rod end drives the moving component 3012 to move upward along the longitudinal groove. The puncture component 3014 then exits from the foaming wheel 1014. Since the entire exit process is controlled by the servo push rod 3011, it avoids the shaking or uneven force that may occur when manually inserting and removing the component, ensuring that the puncture component 3014 exits smoothly, reducing secondary damage to the puncture site of the foaming wheel 1014, and ensuring the accuracy of the experimental results. After completing one puncture test, the moving mechanism 3 can be moved again by the servo motor 201 to perform batch tests on other parts of the foaming wheel 1014, thereby improving experimental efficiency.
