The meaning is that the high molecular rubber material has higher mechanical property, heat resistance, wear resistance and corrosion resistance. Further, it is known that the main production direction of polymer rubber materials is high-performance rubber products, of which the most prominent is high-performance tires, and the requirements for high-performance tires are low rolling resistance (oil saving, pollution reduction); the grip force and the traction force are large on dry, wet and ice-snow road surfaces, and the wear resistance is good. Therefore, when the polymer rubber product is produced as a single product, one small block of the polymer rubber product is often required to be cut to be used as a test sample for wear resistance detection, but the traditional polymer rubber product detection structure is usually operated manually, mechanically polished and then subjected to weight detection, and the wear resistance of the test sample is judged based on the weight before and after a friction test. The mode is not automatic and intelligent enough, wastes time and labor, and causes the efficiency of the wear-resisting detection test of the test sample to be not high.

Further, the patent "CN 112362519B," a rubber wear resistance detection device and detection method ", which discloses" often lead to the sample wearing phenomenon easily in the friction process, make the efficiency of detection equipment wear influence detection, secondly, when the sample receives the friction in the detection process, the stress inequality appears easily and produces the skew phenomenon problem, now proposes following scheme, which comprises a housing, the top of housing articulates there is the closing cap, and a plurality of driving rollers are installed through the bearing in the inside of housing, and the inside fixed mounting of housing has the step motor who is connected with the driving roller transmission, the motion band has been cup jointed in the outside of live-rollers. In the feeding stage, the assembly for fixing the rubber sample can be lifted up through the electric push rod to be separated from the abrasive belt, so that the influence on the abrasive belt in the feeding process can be effectively avoided, and the assembly for fixing the rubber sample is lowered after the rotating speed of the abrasive belt is constant in the detection process, so that the sample is in contact with the abrasive belt, and the detection precision is improved.

It still has the following problems: first, among its the technical scheme who discloses, it is comparatively huge and complicated to detect the structure, the operation of being not convenient for, and the single can only detect the test sample of a rubber component moreover, because it is the sharp friction in plane and detects cooperation structure, if want to carry out the detection of multiple polymer rubber component sample simultaneously, just can only continue to increase the structure in the left right direction, so will lead to detecting that the structure is more huge, and equipment occupation space is bigger, and the price/performance ratio is lower. Secondly, in the technical scheme disclosed by the invention, the detection structure is used for detecting the samples of the same kind of rubber products, the applied positive acting force (namely the downward pressure on the samples) is the same and does not change, namely, the detection structure can only detect the friction degree of the rubber products under single pressure, the test detection effect is poor, the detection result has one-sidedness and is not accurate enough, and the test detection progress can not realize efficient intelligent operation.

In this embodiment, as shown in fig. 4: the elastic member 35 is a compression spring, the compression degree of the compression spring in the telescopic sleeve 32 of the compression member 31 distributed at the innermost side is the largest, and the compression degree of the compression spring in the telescopic sleeve 32 of the compression member 31 distributed from the inside to the outside is gradually reduced. The connecting rods 34 of the outermost distributed pressing pieces 31 are positioned in the uppermost rotating ring 25, and the connecting rods 34 in the innermost distributed pressing pieces 31 are positioned in the lowermost rotating ring 25.

The purpose of this arrangement is that, because the pressing plate 37 and the rubber product sample are pressed on the upper end face of the grinding wheel disc 1, the telescopic rod 33 is inclined, the telescopic sleeve 32 and the connecting lug 36 are rotated, and the connecting rod 34 is horizontally distributed, so that when the connecting rod 34 penetrates through the mounting channel 28 and reaches the rotating ring 25 at a specified position downwards, the connecting rod 34 horizontally distributed firstly presses the toothed plate, the toothed plate 52 moves inwards, and then the connecting rod 34 passes through, and the toothed plate 52 returns to the original position, that is, completely blocks the mounting channel 28. And then the connecting rod 34 can be tightly contacted with the lower end surface of the toothed plate 52, the whole compression length of the telescopic rod and the telescopic sleeve is shaped, and the whole pressing piece 31 does not move any more.

Further, the stress of the compression spring in the innermost telescopic sleeve is analyzed: because the corresponding connecting rod 34 is located in the rotating ring 25 at the lower position, that is, in the balanced structure state shown in fig. 4, the compression spring is compressed to a certain extent, and the compression spring has an upward oblique thrust and a downward oblique acting force when analyzed by taking the compression spring as a stressed element. The oblique upward thrust acts between the connecting rod 34 and the toothed plate 52, and the pressing plate has no moving tendency because of the pressing contact of the connecting rod and the toothed plate. The obliquely downward force has a component of a forward force (referred to as a forward force for short) applied to the rubber product sample, and the larger the forward force is, the larger the friction between the rubber product sample and the grinding wheel disc 1 is. Therefore, the rubber product samples in the same group are guaranteed, the wear resistance under different pressures is detected, the practicability of the equipment is greatly improved, and the equipment has higher popularization value.

In this embodiment, as shown in fig. 5: the drive mechanism 4 comprises a fixed disc 41 and a speed regulating structure 42. Further, as shown in fig. 9: the fixed disc 41 is arranged at the top end of the fixed rod 11 and is in a circular truncated cone structure with a narrow top and a wide bottom, and the fixed disc 41 is provided with a conical surface 412 which is distributed in an annular shape; two fixing holes 413 which are symmetrically distributed are also arranged on the conical surface 412; the fixed tray 41 is further provided at the center of the upper end thereof with a fixing groove 414. The speed regulating structure 42 is configured to drive the uppermost rotating ring 25 and the pressing piece 31 correspondingly connected with the uppermost rotating ring, and the speed increasing value of the movement speed of the grinding wheel disc 1 reaches L1, and so on; the bottommost rotating ring 25 and the pressing piece 31 correspondingly connected with the bottommost rotating ring are driven, the movement speed increasing value of the grinding wheel disc 1 reaches Ln, L1 is more than L2 … is more than Ln-1 and less than Ln is kept, and finally the plurality of pressing pieces 31 in the same group of detection assemblies 3 always keep uniform relative movement speed; meanwhile, when the number of the detection assemblies 3 is larger, the larger the preset height that the upward thrust of the pressing member 31 drives the rotating ring 25 and the supporting plate 22 to move upwards integrally is, the larger the friction transmission force for the rotating ring 25 is.

A further preferred embodiment, as shown in fig. 5: the speed regulating structure 42 comprises a rotating sleeve 43, a driving rod 44, a driving motor 45 and a conical turntable 46. The driving motor 45 is disposed on the end cover 23, and the output end is connected to the driving rod 44. The driving rod 44 penetrates through the supporting plate 22 and extends downwards, a rotating plate 47 is further sleeved on the upper portion of the driving rod 44, and the rotating plate 47 is located on the upper end face of the supporting plate 22 and keeps the supporting plate and the supporting plate to rotate relatively and not to move relatively. The rotating plate 47 also serves as a stroke limit for the up-and-down movement of the rotating sleeve 43.

As shown in fig. 10: the cross section of the rotary sleeve 43 is i-shaped, and the lower end thereof is fitted into the fixing groove 414 so as to be movable relative thereto. The upper part of the rotating sleeve 43 is also provided with a first friction surface 48, the center of the rotating sleeve 43 is provided with a rotating hole 49, and the rotating hole 49 is fixedly connected with the driving rod 44 through threads to keep the rotating sleeve 43 and the driving rod 44 to rotate synchronously.

As shown in fig. 11: the conical turntable 46 is conical in shape, and the inclined surface is in contact with the inner walls of the plurality of rotating rings 25 which are distributed up and down. The center of the horizontal end of the conical turntable 46 is also provided with a rotating shaft 411, and the rotating shaft 411 is rotatably matched and arranged in the fixed hole 413; the outer edge of the horizontal end of the conical turntable 46 is further provided with a second friction surface 410 which is distributed annularly, and the second friction surface 410 and the first friction surface 48 are in friction transmission to drive the conical turntable 46 to rotate.

The purpose of such setting is that, use the rotating sleeve 43 as the sun gear, conical turntable 46 is the planet wheel, forms "planet transmission" complex structure, and rotating sleeve 43 is synchronous with driving motor 45's rotational speed, and driving motor 45 adopts servo motor, and is more stable. The first friction surface 48 on the rotating sleeve 43 and the second friction surface 410 on the conical turntable 46 are in friction transmission, and the friction force between the two is large enough to drive the conical turntable 46 to rotate around the rotating shaft 411.

The inclined surface of the conical turntable 46 is in contact with the inner wall of the rotating ring 25, and the inclined surface and the inner wall are in friction transmission, so that the rotating ring 25 is driven to rotate together. However, the rotation speed of the conical turntable 46 is fixed, but the contact points of the rotating rings 25 distributed up and down and the conical turntable 46 are different, that is, the corresponding radii of the points on the inclined plane of the conical turntable 46 are different, (the radii of the conical turntable 46 corresponding to the points on the inclined plane from top to bottom are gradually increased), so the linear speeds of the positions of the conical turntable 46 corresponding to the different rotating rings 25 are gradually increased from top to bottom, and further the linear speeds of the rotating rings 25 distributed from top to bottom are gradually increased, and the speeds are used for compensation.

It is also necessary to analyze the linear velocity of the polymeric rubber product sample and the entire pressing plate 37 (i.e., the relative movement velocity of the entire sample and pressing plate with respect to the grinding wheel). The rotation speeds (i.e., the angular speeds w) of the plurality of rotating rings 25 distributed up and down are the same regardless of the influence of the speed regulating structure, and are analyzed for the innermost distributed compacting plates 37: as shown in fig. 4, since the relative radius r of the pressing plate 37 distributed at the innermost side on the grinding wheel disc 1 is the smallest, and v = w r, the relative movement speed v of the pressing plate 37 distributed at the innermost side is the smallest, and the speed increase value to be compensated is the largest, and so on, the relative movement speed v of the pressing plate distributed at the outer side with a larger radius in the same group of detection assemblies is the largest, and the speed increase value to be compensated is the smallest, and since the intelligent rubber product detection is performed to control a single variable, the relative movement speed v of the pressing plates in the same group of detection assemblies needs to be unified.

Through the linear velocity compensation of above-mentioned analysis, so formed promptly to the same group in the detecting component 3 on different rotating ring 25 correspond pressure strip 37, the relative movement speed of polymer rubber goods sample carries out acceleration rate effect, and then guarantees that a plurality of pressure strips in the same group detecting component are in a same relative movement speed all the time. The final objective is to form a single variable control: different pressure strips 37 and rubber products samples in the same group of detection assemblies 3 are integrated, and on the premise that the same phase movement speed rotates, different positive acting forces are applied to intelligent wear-resistant detection of the rubber products.

In this embodiment, as shown in fig. 3: the fixing groove 414 is communicated with the fixing hole 413, a communicated area between the fixing groove 414 and the fixing hole 413 is filled with hydraulic oil 7, the lower end of the rotating sleeve 43 can slide up and down in the fixing groove 414, and the rotating shaft 411 can move inside and outside along the fixing hole 413; when the support plate 22 drives the rotating sleeve 43 to move upwards, the rotating sleeve 43 pushes the hydraulic oil 7 to flow into the fixing hole 413, and pushes the conical turntable 46 to move outwards, so that the friction transmission force between the conical turntable 46 and the rotating ring 25 is increased. Sealing gaskets are arranged between the rotating shaft 411 and the fixing hole 413 and between the middle part of the rotating sleeve 43 and the fixing groove 414.

The purpose of the arrangement is that a plurality of mounting channels 28 which are uniformly distributed in an annular shape are arranged on the rotating ring 25, and the corresponding mounting channel 28 is used for detecting the wear resistance of a group of high polymer rubber products with specification and model; when the types of the specifications and the models of the samples of the high polymer rubber products are more, the number of the detection assemblies 3 is more, the pressure spring in the telescopic sleeve 32 is in a compressed state, and an oblique upward thrust is generated in the direction opposite to the toothed plate 52, and when the upward thrust of the plurality of pressing pieces 31 is large enough (namely, in the state, the number of the detection assemblies to be configured is too large and the number of the samples of the rubber products of the types of the specifications and the models to be detected is too large at the same time), the rotating ring 25 and the supporting plate 22 are driven to move upwards integrally for a preset height. The supporting plate 22 moves upwards, the fixing plate 21 and the fixing disc 41 are not moved, and the end cover 23, the fixing frame 24 and the grinding wheel disc 1 synchronously move upwards by a small distance.

As shown in fig. 4 and 5: the larger the height of the upward movement of the support plate 22, the larger the upward movement distance of the rotating sleeve 43 (however, since the inclined surface of the conical turntable 46 is in contact with the inner wall of the rotating ring 25 in the initial state, and the moving range of the rotating sleeve 43 relative to the mounting groove 27 is limited, sufficient stroke is ensured). Therefore, the lower end of the rotating sleeve 43 pushes the hydraulic oil 7 more, and the larger the hydraulic oil entering the fixing hole at the lower part of the conical turntable is, the larger the lifting effect is on the conical turntable, so that the outward moving distance of the conical turntable 46 is larger, the friction transmission force between the inclined surface of the conical turntable 46 and the rotating ring 25 is increased, the phenomenon of 'slipping' of the rotating ring 25 is avoided, and the sufficient rotating force is ensured.

The working process is as follows:

a group of detection components 3 corresponds to the wear resistance detection of a group of rubber product samples of specification models, so a single group of detection components 3 can be analyzed. In an initial state, a plurality of cut polymer rubber product samples of the same specification and model are sequentially fixed on corresponding pressure plates 37 respectively, and the specific operations are as follows: the tip of rubber products sample is crossed at the arc wall 39 at first and is placed, and then the staff drives threaded rod 62 and rotates through clockwise turning knob 63 to drive compressing rod 64 and move down in step, until compressing rod 64 with the experimental sample of rubber products, tightly press in arc wall 39, form the roof pressure and fasten the structure, prevent that rubber products from slipping at wear-resisting test in-process.

The worker then presses the connecting rods 34 of the pressing elements 31 one after the other into the mounting channel 28, up to the position of the corresponding rotary ring 25. Taking the three-set pressing member 31 structure shown in fig. 4 as an example, the connecting rod 34 connected to the innermost telescopic rod 33 is first pressed into the installation channel 28 to the third distributed rotating ring 25 position. Specifically, the worker holds the telescopic rod 33 by hand, so that the connecting rod 34 sequentially passes through the upper rotating ring 25, the latch structure 5 automatically extends and retracts and returns, and when the connecting rod 34 connected with the innermost telescopic rod 33 reaches the rotating ring 25 distributed on the third layer. In this state, due to the cooperation of the compression spring and the connecting rod in the telescopic sleeve 32, the pressing plate 37 connected to the innermost telescopic rod 33 and the rubber product sample are positioned between the whole body and the grinding wheel disc 1 and do not move any more.

Meanwhile, the connecting rod 34 connected with the telescopic rod 33 and the toothed plate 52 distributed on the third layer form a jacking structure and do not move any more. The innermost pressure piece 31 (described here based on the structure of the grinding wheel disk 1) is positioned. By analogy, the connecting rods 34 corresponding to the pressing pieces 31 distributed on the outermost side are installed at the rotating rings 25 distributed on the first layer (i.e., the uppermost layer in the figure), and are pressed by the corresponding toothed plates 52, so as to finally form the distribution structure of the pressing pieces 31 as shown in fig. 4.

At the moment, the fixed installation of three polymer rubber product samples and the rotating ring is also finished. Furthermore, the three polymer rubber product samples of the second specification type can be fixedly installed in sequence by adopting the operation. By analogy, in the present embodiment, as shown in fig. 1: four groups of detection assemblies 3 are installed, and four rubber product samples of different specifications and models can be correspondingly and simultaneously detected for the wear resistance.

After the worker completes the above operation, the driving motor 45 is started, and the driving motor 45 drives the driving rod 44 to rotate synchronously, so as to drive the rotating sleeve 43 to rotate synchronously. The first friction surface 48 on the rotating sleeve 43 and the second friction surface 410 on the conical turntable 46 are in friction transmission, and the friction force between the two is large enough to drive the conical turntable 46 to rotate around the rotating shaft 411.

The inclined surface of the conical turntable 46 is in contact with the inner wall of the rotating ring 25, and the inclined surface and the inner wall are in friction transmission, so that the rotating ring 25 is driven to rotate together. Meanwhile, the rotating sleeve 43 is used as a sun gear, and the conical turntable 46 is used as a planet gear to form a speed regulating structure 42 of planetary transmission. Because the rotating speed of the conical turntable 46 is fixed, but the contact points of the rotating rings 25 distributed up and down and the conical turntable 46 are different, that is, the corresponding radiuses of the points on the inclined plane of the conical turntable 46 are different, (the radiuses of the conical turntable 46 corresponding to the points on the inclined plane from top to bottom are gradually increased), the linear speeds of the positions of the conical turntable 46 corresponding to the different rotating rings 25 are gradually increased from top to bottom, and further the linear speeds of the rotating rings 25 distributed up and down are gradually increased, and the speeds are used for compensation.

Further, the relative movement speed v of the pressing plate 37 and the rubber product sample distributed at the outermost side of the detecting assembly 3 in the same group is the largest, the speed increase value to be compensated is the smallest, and so on. The purpose of unifying the relative movement speed v of the pressure plates 37 in the same group of detection assemblies 3 can be realized, and an accurate detection basis is provided for the control of subsequent single variables.

Wherein, with the atress analysis of the pressure spring in the most inboard telescopic sleeve 32: because the corresponding connecting rod 34 is located in the rotating ring 25 at the lower position, that is, in the balanced structure state shown in fig. 4, the compression spring is compressed to a certain extent, and the compression spring has an upward oblique thrust and a downward oblique acting force when analyzed by taking the compression spring as a stressed element. The oblique upward thrust acts between the connecting rod 34 and the toothed plate 52, and the connecting rod and the toothed plate are in pressing contact, so that the connecting rod and the toothed plate do not tend to move. The obliquely downward acting force has a component of a forward action (referred to as a forward acting force for short) applied to the rubber product sample, and the larger the forward acting force is, the larger the friction between the rubber product sample and the grinding wheel disc 1 is, so that the forward acting force of the pressing plate 37 of the pressing member 31 distributed at the innermost side is the largest, and by analogy, the forward acting force of the pressing plate 37 of the pressing member 31 distributed at the outermost side is the smallest.

Thus, by intelligently controlling a single variable: different pressure plates 37 and the rubber product sample in the same group of detection assemblies 3 are integrally subjected to intelligent wear-resistant detection on the rubber product sample by applying different forward acting forces on the premise of the same relative movement speed; the wear-resisting detection of the polymer rubber product samples of various specifications and models can be carried out simultaneously, and the method is more practical.

In the actual testing process, when the specification and model types of the sample of the high polymer rubber product are more, the configuration quantity of the detecting components 3 is more, the pressure spring in the telescopic sleeve 32 is in a compressed state, an oblique upward thrust is generated in the direction opposite to the toothed plate 52, and when the upward thrust of the plurality of pressing pieces 31 is large enough, the rotating ring 25 and the supporting plate 22 are driven to move upwards by a small distance integrally. The supporting plate 22 moves upwards, the fixing plate 21 and the fixing disc 41 are not moved, and the end cover 23, the fixing frame 24 and the grinding wheel disc 1 synchronously move upwards by a small distance. Therefore, the rotating sleeve 43 moves upwards to push hydraulic oil, the hydraulic oil enters the fixing hole in the lower portion of the conical turntable and has a jacking effect on the conical turntable, the conical turntable 46 moves outwards for a small distance, the inclined surface of the conical turntable 46 is enabled to increase the friction transmission force between the rotating rings 25, the resistance is avoided being too large, the phenomenon that the rotating rings 25 slip is avoided, and the sufficient rotating force is guaranteed through automatic and intelligent adjustment.

Example 2: on the basis of example 1, as shown in fig. 3: the fixing rod 11 is provided with a baffle table 12 below the fixing plate 21, an elastic gasket 13 is arranged between the baffle table 12 and the fixing plate 21 and is in contact with the fixing plate 21, the elastic gasket 13 exerts elastic pre-tightening effect on the fixing plate 21, installation and jacking are facilitated, and stability of a detection test is further guaranteed.

Example 3: on the basis of embodiment 2, in order to ensure reasonable and efficient rotation operation of the intelligent detection device, the high-molecular rubber product is efficiently detected for accurate wear resistance, and an actual detection process is combined, as shown in fig. 1: the rotating rings 25 are provided in four spaced-apart vertical positions. Eight T-shaped grooves 26 are uniformly distributed on each rotating ring 25, eight mounting channels are correspondingly arranged on the rotating rings, and the rotating rings can be freely selected when actual rubber products are detected. Wherein, in this embodiment, preferably, determine module 3 is four groups of annular equipartition, and what correspond can detect the test of the polymer rubber goods sample wear resistance of four kinds of different specification models simultaneously, and spatial structure reasonable in design occupies a small space, and the high-usage has improved the detection efficiency of this equipment greatly. Further, every detection element 3 of group still includes three and compresses tightly the piece 31, and what correspond is with three rubber component samples in the detection element 3 of group, under the prerequisite of the same relative motion velocity, applys three kinds of different forward forces and to the intelligent wear-resisting detection of rubber component, better improvement the degree of accuracy that wear resistance detected.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
