Description

Technical Field

[0001] The present invention relates to the technical field of wear resistance detection, and particularly to a device for detecting the wear resistance of foam materials. Background Art

[0002] The closed-cell foamed silicone rubber foam material has good shock absorption, sound insulation, heat insulation, and flame retardant properties. In the automotive field, it is mainly used for heat insulation foam pipes for vehicle air conditioners, automotive shock absorption, and foamed silicone rubber gaskets for new energy vehicle batteries.

[0003] In order to facilitate clamping and detecting materials, the wear resistance detection devices in the prior art generally adopt the detection method of placing the detection material in a positive direction. For example, a Chinese patent with the patent publication number CN215004682U discloses a device for detecting the wear resistance of polyurethane foam, including a testing device. One end of the second telescopic rod is provided with a movable block, and a grinding block is arranged below the movable block, and a foam main body is arranged below the grinding block. A rotating disk is arranged below the foam main body, and a fixed block is arranged at one end of the rotating disk, and a first telescopic rod is arranged in the middle of the fixed block. One end of the first telescopic rod is connected to a clamping block, and the first telescopic rod is connected to a first shaft rod through a first parallel gear meshing with a first gear. The other end of the first shaft rod is connected to a first connecting shaft through a third gear set, and the first connecting shaft is connected to a second connecting shaft through a fourth gear set. A second motor is arranged below the rotating disk.

[0004] Although the above technical solution can detect the wear resistance of the foam, during the wear resistance detection process, a large amount of debris will be generated on the foam. The method of placing the foam in a positive direction will cause the debris to accumulate on the surface of the foam, and the accumulated debris will change the actual contact state between the foam and the grinding block, affecting the accuracy of the wear resistance detection. If the debris is cleaned by means of dust suction or blowing, the air flow rate around the foam will increase, thereby strengthening the heat exchange between the foam and the surrounding environment, causing the foam to expand or contract, and it is difficult to simulate the wear state of the foam under natural temperature conditions, resulting in deviation of the detection results. Summary of the Invention

[0005] In order to overcome the drawback that placing the foam in a positive direction will cause debris to accumulate on the surface of the foam and the accumulated debris will affect the wear resistance detection accuracy, the present invention provides a device for detecting the wear resistance of foam materials. On the basis of retaining the positive clamping function, it can also make the debris on the surface of the foam automatically fall by gravity, and there is no need to introduce air flow to clean the debris, avoiding the interference of air flow on the state of the foam and improving the accuracy of the wear resistance detection.

[0006] The technical solution is as follows: A wear resistance detection device for foam materials, including a detection base, on which a sliding frame is slidably connected. An electric push rod for driving the sliding frame to slide is fixedly connected to the detection base. A detection table for placing the foam to be detected is rotatably connected to the sliding frame. A sliding plate is slidably connected to the support plate on the detection base, and a detection plate is installed on the sliding plate. The detection plate is used to rub the foam for detection. A first gear is fixedly connected to the rotating shaft of the detection table, and a first rack is fixedly connected to the detection base. The first gear and the first rack cooperate to drive the detection table to rotate, so that the foam can be first placed on the upper end of the detection table, and then the detection table drives the foam to the lower side for detection.

[0007] Furthermore, it also includes a driving mechanism for driving the sliding plate to move. The driving mechanism includes a machine base, which is fixedly connected to the detection base. A servo motor is fixedly connected to the machine base. A swing rod is fixedly connected to the output shaft of the servo motor. A sliding shaft is fixedly connected to the end of the swing rod far from the servo motor. An engagement frame is fixedly connected to the sliding plate, and the sliding shaft is slidably arranged in the linear slideway on the engagement frame.

[0008] Furthermore, it also includes a knocking mechanism for knocking the foam to shake off debris. The knocking mechanism includes knocking frames. Two knocking frames are symmetrically and slidably connected to the detection table. A first spring is sleeved on the guide rod of the knocking frame. Knocking blocks are fixedly connected to the ends of the knocking frames close to the detection table. The knocking blocks are used to knock the back of the foam to shake off the debris.

[0009] Furthermore, the right knocking block will knock the foam only when the detection plate moves to the lower left side of the foam. On the contrary, the left knocking block will knock the foam only when the detection plate moves to the lower right side of the foam.

[0010] Furthermore, the knocking mechanism also includes a first connecting rod, which is fixedly connected to the left knocking frame. A second connecting rod is fixedly connected to the right knocking frame. A resisting seat is slidably connected to the sliding plate. A second spring is connected between the resisting seat and the sliding plate. A sliding rod is rotatably connected to the resisting seat. A top rod is fixedly connected to the resisting seat. The top rod is used to push the first connecting rod and the second connecting rod upward. Two groups of lifting rods are fixedly connected to the detection table. The lifting rods are used to guide the sliding rod to facilitate the upward movement of the resisting seat.

[0011] Furthermore, it also includes a cleaning component for cleaning the detection plate. The cleaning component includes a cleaning frame, which is fixedly connected to the sliding frame. Cleaning rods are rotatably connected to the cleaning frame. Brush hairs are arranged at the lower ends of the cleaning rods. The cleaning rods are used to clean the top of the detection plate.

[0012] Furthermore, the cleaning component also includes a second gear, which is fixedly connected to the rotating shaft of the cleaning rod. A second rack is fixedly connected to the sliding plate. When the telescopic shaft of the electric push rod extends half of its stroke, the left and right movement of the sliding plate will drive the cleaning rod to rotate through the second gear and the second rack.

[0013] Further, it also includes clamping plates. The two clamping plates are rotatably connected to the detection table, and the clamping plates are used to press the foam tightly on the detection table.

[0014] Further, it also includes a torsion spring. The torsion spring is sleeved on the rotating shaft of the clamping plate, and the torsion spring is fixedly connected to the clamping plate and the detection table. A locking wheel is fixedly connected to the rotating shaft of the clamping plate. A locking frame is slidably connected to the detection table. When the locking wheel enters the groove on the locking frame, it cannot rotate. A third spring is sleeved on the guide rod to which the locking frame and the detection table are slidably connected.

[0015] Further, it also includes a collection box for collecting debris. The two collection boxes are symmetrically placed on the ground on both sides of the machine base.

[0016] Compared with the prior art, the present invention has the following advantages: The detection table of this device is set as a flipable structure, which not only retains the function of placing the foam on the front side, facilitating the quick clamping of the foam for detection, but also enables the debris to automatically fall by gravity, effectively preventing the debris from accumulating on the surface of the foam. Moreover, there is no need to introduce air flow to clean the debris, avoiding the interference of the air flow on the state of the foam and improving the accuracy of the wear resistance detection; during the detection process of this device, when the detection plate moves to the lower left side of the foam, the knocking block on the right side can synchronously strike the right back of the foam, and vice versa, striking the left back of the foam, using the vibration generated by the knocking to accelerate the falling of the debris on the surface of the foam, further ensuring the detection accuracy; when the telescopic shaft of the electric push rod extends halfway during the detection process of this device, it is in a self-cleaning state. At this time, the reciprocating movement of the sliding plate can drive the cleaning rod to rotate through the second gear and the second rack, automatically cleaning the debris on the surface of the detection plate to ensure the continuity of the detection.

Specific implementation mode

[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0026] Embodiment 1: A wear resistance detection device for foam materials, as Figure 1 - Figure 2 shown, includes a detection base 10, a sliding frame 11, a detection table 12, a support plate 13, a sliding plate 14, a detection plate 15, a first gear 16, a first rack 17 and an electric push rod 61. Two symmetrically arranged sliding frames 11 are slidably connected to the upper side of the detection base 10, and both sliding frames 11 slide in the vertical direction. An electric push rod 61 is fixedly connected to the detection base 10, the telescopic shaft of the electric push rod 61 is arranged downward, and the telescopic shaft of the electric push rod 61 is fixedly connected to one of the sliding frames 11. A detection table 12 is rotatably connected to the two sliding frames 11 together, and the detection table 12 is rotationally connected in a damping manner to prevent it from rotating randomly. The detection table 12 is used to place the foam to be detected. Two support plates 13 are symmetrically and fixedly connected to the lower side of the detection base 10. Slideways are opened at one end of the two support plates 13 facing each other. A sliding plate 14 is slidably connected to the slideways of the two support plates 13 together. The sliding plate 14 slides in the left - right direction. A detection plate 15 is installed on the sliding plate 14. The detection plate 15 is located below the detection table 12. Technicians can set a pressure sensor and an automatic adjustment system on the detection plate 15 to adjust the pressure between the detection plate 15 and the foam. This setting method is a conventional setting in the wear - resistance detection device and will not be described in detail here. Combining Figure 1 and Figure 2 it can be seen that the rotating shafts on both sides of the detection table 12 pass through the same - side sliding frame 11 and extend outwards, and first gears 16 are fixedly connected to the outer - extending ends of the rotating shafts of the detection table 12. A first rack 17 is fixedly connected to the detection base 10. During the downward movement of the sliding frame 11, the first gear 16 and the first rack 17 cooperate to drive the detection table 12 to rotate 180 degrees, which is convenient for first placing the foam on the upper end of the detection table 12 and can also drive the foam to rotate and face the sliding plate 14 for easy detection, so that the debris generated by friction can fall downward to avoid accumulation.

[0027] AsFigure 1 , Figure 5 and Figure 6 As shown in Figure 1 , Figure 5 and Figure 6 , it further includes a driving mechanism for driving the movement of the slide plate 14. The driving mechanism is installed on the detection base 10. The driving mechanism includes a machine base 30, a servo motor 31, a swing rod 32, a sliding shaft 33 and a connection frame 34. The machine base 30 is fixedly connected to the detection base 10. The machine base 30 is located below the two support plates 13. The servo motor 31 is fixedly connected to the lower side of the machine base 30. The output shaft of the servo motor 31 passes through the machine base 30 upward, and the swing rod 32 is fixedly connected to the output shaft of the servo motor 31. One end of the swing rod 32 far from the output shaft of the servo motor 31 is fixedly connected to the sliding shaft 33, and the sliding shaft 33 is located at the top end of the swing rod 32. The lower end of the slide plate 14 is fixedly connected to the connection frame 34. A linear through-hole slideway is formed on the connection frame 34. The sliding shaft 33 is slidably arranged in the slideway on the connection frame 34.

[0028] As Figure 1 shown in Figure 1 , it further includes a collection box 60 for collecting debris. The two collection boxes 60 are symmetrically placed on the ground on both sides of the machine base 30.

[0029] When the foam needs to be detected, first, the worker fixes the cut foam on the upper end of the detection table 12, and then controls the electric push rod 61 to fully extend downward, thereby driving the sliding frame 11 and the detection table 12 to move downward. During this process, the first rack 17 and the first gear 16 will engage and drive the detection table 12 to rotate 180 degrees, so that the foam will rotate to the lower end of the detection table 12, and then the foam will move downward and contact the top end of the detection plate 15; then start the servo motor 31. Every time the output shaft of the servo motor 31 drives the swing rod 32 to rotate one week, the swing rod 32 will drive the slide plate 14 to reciprocate left and right once through the sliding shaft 33 and the connection frame 34; when producing this equipment, a PLC control system is added to control the number of rotations of the servo motor 31, so as to accurately control the number of friction times between the detection plate 15 and the foam. After the friction is over, the staff records and analyzes the detected data to evaluate whether the wear resistance of the foam meets the standard; when the detection plate 15 moves, a frictional force will be generated between the detection plate 15 and the foam, and the foam itself will be worn. The debris generated by the wear can fall downward into the collection box 60 under the action of gravity, avoiding a large amount of debris accumulating on the foam test block to affect the detection accuracy.

[0030] Embodiment 2: On the basis of Embodiment 1, as Figure 2 - Figure 5As shown in the figure, it further includes a knocking mechanism for knocking the foam to shake off debris. The knocking mechanism cooperates with the sliding plate 14. The knocking mechanism includes a knocking frame 20, a first spring 21, a knocking block 22, a first connecting rod 23, a second connecting rod 24, a supporting seat 25, a sliding rod 26, a second spring 27, a lifting rod 28 and a top rod 29. Two knocking frames 20 are symmetrically and slidably connected to the inspection table 12. The knocking frames 20 are located on the side of the inspection table 12 away from the foam. A first spring 21 is sleeved on the guiding rod of the knocking frame 20. The first spring 21 is used to push the knocking frame 20 close to the inspection table 12. A square through hole is opened on the inspection table 12. Sixteen knocking blocks 22 are fixedly connected in an array at one end of the knocking frame 20 close to the inspection table 12. The knocking blocks 22 are located in the through hole opened on the inspection table 12. The knocking blocks 22 are used to knock the back of the foam to shake off the debris; A first connecting rod 23 is fixedly connected to the left knocking frame 20. The first connecting rod 23 extends to the right. A second connecting rod 24 is fixedly connected to the right knocking frame 20. The second connecting rod 24 extends to the left. Two supporting seats 25 are symmetrically and slidably connected to the sliding plate 14. The supporting seats 25 all slide in the vertical direction. A second spring 27 is sleeved on the guiding rod connected to the sliding plate 14 and the supporting seat 25. And the lower end of the second spring 27 is fixedly connected to the supporting seat 25. The upper end of the second spring 27 is fixedly connected to the guiding rod of the supporting seat 25, so that the second spring 27 can be stretched and stored energy when the supporting seat 25 moves downward. A sliding rod 26 is rotatably connected to the supporting seat 25. A top rod 29 is fixedly connected to the top of the supporting seat 25. The top rod 29 is used to push the first connecting rod 23 and the second connecting rod 24 upward. Two groups of lifting rods 28 are symmetrically and fixedly connected to the front and back sides of the inspection table 12. Each group of lifting rods 28 has two. The lifting rods 28 are used to guide the sliding rod 26 to facilitate the upward movement of the supporting seat 25; It should be noted that the second spring 27 is used to keep the supporting seat 25 at a fixed height when there is no other external force acting on it, and when the supporting seat 25 is at this height, the sliding rod 26 is higher than the lower end of the lifting rod 28, so that when the sliding rod 26 moves between the left and right groups of lifting rods 28, the height of the sliding rod 26 is higher than the lower end of the lifting rod 28, so as to facilitate the upward movement of the sliding rod 26 along the lifting rod 28.

[0031] When the inspection plate 15 moves to the lower left side of the foam, the knocking block 22 on the right knocking frame 20 will knock the foam downward. On the contrary, when the inspection plate 15 moves to the lower right side of the foam, the knocking block 22 on the left knocking frame 20 will knock the foam downward.

[0032] During the leftward movement of the sliding plate 14, the sliding rod 26 will move upward along the left lifting rod 28. The sliding rod 26 will drive the supporting seat 25 to slide upward and compress the second spring 27. The upward movement of the supporting seat 25 will push the second connecting rod 24 upward through the top rod 29. The second connecting rod 24 will drive the right knocking frame 20 to slide upward and compress the first spring 21. From Figure 3It can be seen that taking a group of lifting rods 28 on the left as an example, the distance between the left sides of the two groups of lifting rods 28 increases, and the distance between them here is greater than the length of the sliding rod 26. When the sliding plate 14 moves to the leftmost side, the sliding rod 26 will be disengaged from the lifting rod 28. The second spring 27 pushes the abutment 25 downward to reset, and the first spring 21 pushes the right knocking frame 20 downward to reset, so as to strike the top end of the right side of the foam, and shake off the debris on the lower end surface of the foam through the striking action. Similarly, when the sliding plate 14 moves to the right, the sliding rod 26 will move upward along the right lifting rod 28, and the ejector rod 29 will push the first connecting rod 23 upward. When the sliding plate 14 moves to the rightmost side, the left knocking frame 20 will reset downward to strike the top end of the left side of the foam through the knocking block 22.

[0033] Embodiment 3: On the basis of Embodiment 2, as Figure 2 and 5 shown, it further includes a cleaning assembly for cleaning the detection plate 15. The cleaning assembly is connected to the sliding frame 11. The cleaning assembly includes a cleaning frame 40, cleaning rods 41, a second gear 42 and a second rack 43. Cleaning frames 40 are fixedly connected to opposite sides of the two sliding frames 11. The cleaning frames 40 extend downward below the detection table 12. Two cleaning rods 41 are rotatably connected to each cleaning frame 40. Brush hairs are arranged at the lower ends of the cleaning rods 41. The cleaning rods 41 are used for cleaning the top end of the detection plate 15. Second gears 42 are fixedly connected to the rotating shafts of the cleaning rods 41. Four second racks 43 are symmetrically fixedly connected to the sliding plate 14. When the electric push rod 61 drives the sliding frame 11 to move downward to half of the stroke, or to reset upward to half of the stroke, the left and right movement of the sliding plate 14 will drive the cleaning rods 41 to rotate through the second gears 42 and the second racks 43.

[0034] When the electric push rod 61 only extends or only contracts by half of the stroke, the device enters the self-cleaning state at this time. Then control the servo motor 31 to rotate. At this time, the left and right movement of the sliding plate 14 will drive the second rack 43 to engage with the second gears 42 on both sides, thereby driving the cleaning rods 41 to rotate. The brush hairs at the lower ends of the cleaning rods 41 will clean the top end of the detection plate 15, and from Figure 1 and Figure 2 it can be seen that the two cleaning rods 41 on the same cleaning frame 40 are arranged in a staggered manner. This setting is to avoid the collision between the two cleaning rods 41 while increasing the cleaning area. When the output shaft of the servo motor 31 rotates a fixed number of turns, it can stop, so as to realize the automatic cleaning of the detection plate 15. Then control the electric push rod 61 to continue to extend to start the detection, or control the electric push rod 61 to continue to contract to remove the foam. It should be noted that the output shaft of the servo motor 31 will rotate a fixed number of turns each time. When the servo motor 31 stops, the sliding plate 14 will be in the Figure 1 intermediate state shown, so as to avoid the collision between the cleaning rods 41 and the detection plate 15 during the downward or upward movement of the sliding frame 11.

[0035] Embodiment 4: On the basis of Embodiment 3, as Figure 2 shown, it further includes a clamping plate 50 for fixing the foam. Two clamping plates 50 are symmetrically and rotatably connected to the detection table 12. The clamping plate 50 can rotate to press the foam against the detection table 12.

[0036] As Figure 2 and Figure 7 shown, it further includes a torsion spring 51, a locking wheel 52, a locking frame 53 and a third spring 54 for locking the clamping plate 50. A torsion spring 51 is sleeved on the rotating shaft of the clamping plate 50. One end of the torsion spring 51 is fixedly connected to the clamping plate 50, and the other end of the torsion spring 51 is fixedly connected to the detection table 12. A locking wheel 52 is fixedly connected to the rotating shaft of the clamping plate 50. The locking wheel 52 is in the shape of a gear. The locking frame 53 is slidably connected to the detection table 12 in the horizontal direction. A groove is formed in the locking frame 53, and the shape of the groove matches the shape of the locking wheel 52. When the locking wheel 52 enters the locking frame 53, it cannot rotate. A third spring 54 is sleeved on the guide rod where the locking frame 53 and the detection table 12 are slidably connected. The third spring 54 is used to push the locking frame 53 close to the locking wheel 52.

[0037] When clamping the foam is needed, first place the cut foam test block on the upper end of the detection table 12, and then the worker first pulls one side of the locking frame 53 outwards to make the locking frame 53 and the locking wheel 52 out of contact. Then the worker rotates and presses the corresponding clamping plate 50 to make the clamping plate 50 press against one end of the foam. Then make the locking frame 53 reset. By restricting the rotation of the locking wheel 52 through the locking frame 53, the clamping plate 50 is kept clamping the foam, and then the other side of the foam is clamped by the other clamping plate 50; when the foam needs to be removed, just pull the locking frame 53 downwards, and the clamping plate 50 will rotate and reset to the Figure 2 vertical state in
