Description

Technical Field

[0001] The invention relates to the technical field of rubber hardness and elasticity detection, in particular to a fully automatic rubber counterweight hardness and elasticity detection device. Background Art

[0002] The rubber counterweight is an important component used in the car air conditioner to reduce the vibration of the vibrating parts or the components connected to the vibrating parts (such as the compressor copper tube). The main function of the rubber counterweight on the copper tube of the car air-conditioning compressor is to reduce vibration and noise. The air-conditioning compressor will generate vibration and noise when working. The rubber counterweight can effectively absorb and attenuate these vibrations through its elasticity and mass, thereby reducing noise. The copper tube may resonate at certain frequencies, resulting in increased noise and component wear. The rubber counterweight can change the vibration characteristics of the copper tube to avoid the resonance frequency from coinciding with the operating frequency of the compressor, thereby reducing the resonance phenomenon. At the same time, since the copper tube plays the role of transmitting refrigerant in the car air-conditioning system, vibration and impact may cause fatigue and damage to the copper tube. The rubber counterweight can provide additional support and protection, reduce the stress and wear of the copper tube, and extend its service life. Finally, by reducing vibration, noise and resonance, the rubber counterweight can improve the stability and reliability of the entire air-conditioning system and ensure that the system can operate normally under various working conditions.

[0003] The hardness and elasticity of the rubber weight directly affect its vibration reduction effect. Appropriate hardness and elasticity can effectively absorb and attenuate vibration. If the hardness is too high, the rubber may be too stiff and unable to effectively absorb vibration; if the hardness is too low, the rubber may be too soft and unable to provide sufficient support. By adjusting the hardness and elasticity of the rubber weight, the vibration frequency of the copper tube can be adjusted to prevent the occurrence of resonance. If the hardness and elasticity do not meet the design requirements, the system may resonate at a specific frequency, increasing noise and damage risks. By testing the hardness and elasticity, the performance of each weight can be ensured to be consistent, thereby ensuring the stability and reliability of the entire air conditioning system. Testing can detect deviations in the production process, ensure that each product meets the design specifications and quality standards, ensure that the rubber weight can play its intended role in actual use, provide effective vibration reduction and noise reduction and protection, and ensure the normal operation and long-term durability of the automotive air conditioning system.

[0004] The Chinese patent with the existing authorization announcement number CN210119406U discloses an elasticity detection device for rubber products, including a base, wherein a placement groove is provided inside the base. In the elasticity detection device for rubber products, a worker first places the rubber product in the rear clamping die, then rotates the locking bolt to make the front clamping die approach the rear clamping die, and fixes the rubber product, and then pulls the other end of the rubber product to the sleeve plate and clamps it by the fixed clamp, and then the control box starts the motor to drive the lead screw to rotate, and the sleeve plate starts to be stretched along the lead screw under the cooperation of the mounting frame and the guide sleeve, when the rubber product is broken, the directional impact force generated is transmitted to the rear clamping die and the sleeve plate, and the sleeve plate is prevented from being offset due to vibration under the action of the limit rod and the guide sleeve, and the force in the rear clamping die is transmitted to the connecting block, and the force is absorbed by the joint action of the shock absorbing spring and the positioning column, thereby achieving the purpose of having a protective structure.

[0005] However, the above technical solution can only be inspected one by one by operators, and it is impossible to realize automatic inspection of the assembly line, and the inspection efficiency is low. At the same time, it is difficult to fix and clamp the annular rubber products such as rubber counterweights. For rubber counterweights, manual inspection of rubber counterweights is still adopted in the actual production process, so the efficiency is low and the inspection accuracy is not high. It is easy to cause errors due to personal habits and experience differences, and the labor cost is high. Summary of the invention

DETAILED DESCRIPTION

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0041] Example 1

[0042] Reference Figure 1-Figure 9 , which is the first embodiment of the present invention, provides a fully automatic rubber counterweight hardness and elasticity detection device, including a supporting mechanism, a conveying mechanism and a detection mechanism. The hardness of the rubber counterweight 102 is judged by the pressing depth of the probe 302, and the hardness difference in different areas is compared and intuitively displayed through the pointer 3024. Finally, the elasticity is judged by the rebound speed of the detection frame 301, so as to realize the assembly line hardness and elasticity detection of the rubber counterweight 102. The operation is simple and the detection efficiency is high. At the same time, the uniformity of product hardness is guaranteed, the product quality is improved, and the occurrence of local wear is prevented.

[0043] Specifically, it includes a supporting mechanism, including a shell 100, a feed bin 101 arranged on the upper end surface of the shell 100, and a rubber counterweight 102 movably arranged in the feed bin 101, the rubber counterweight 102 is a hollow ring rubber block cut on one side, the rubber counterweight 102 is stacked in the feed bin 101, and an outlet 1011 is opened on the side wall of the feed bin 101, and the rubber counterweight 102 flows into the shell 100 along the outlet 1011 for dimensional accuracy detection;

[0044] The conveying mechanism includes a conveying pipe 200 arranged on the outer wall of the feed bin 101, a guide shaft 201 fixedly arranged at the center of the conveying pipe 200, a material moving claw 202 movably arranged inside the conveying pipe 200, and a pushing hopper 203 slidably arranged at the bottom of the feed bin 101. When the pushing hopper 203 moves upward along the feed bin 101, it pushes the rubber counterweight 102 along the outlet 1011 into the conveying pipe 200 and sleeves on the guide shaft 201. When the material moving claw 202 moves, it drives the rubber counterweight 102 to slide along the guide shaft 201;

[0045] The detection mechanism includes a linkage assembly 300 arranged on one end surface of the material moving claw 202, a detection frame 301 arranged on one end of the linkage assembly 300 and a probe 302 slidably arranged on the detection frame 301. Two probes 302 are symmetrically arranged, and a balance oil pipe 3021 is sealed between the two probes 302. The hardness is determined according to the depth of the probe 302 pressed downward into the rubber counterweight 102, and whether the hardness is evenly distributed is determined according to the liquid level of the balance oil pipe 3021. The elasticity of the rubber counterweight 102 is determined according to the rebound speed of the detection frame 301 after the linkage assembly 300 is released.

[0046] Among them, the rubber counterweight block 102 is normally movably mounted on the outer wall of the automobile air-conditioning cooling pipe to reduce the vibration of the air-conditioning copper pipe. At the same time, the rubber counterweight block 102 needs to have a certain elasticity and hardness under normal circumstances to ensure that it is firmly mounted on the outer wall of the cooling pipe and will not fall off.

[0047] Preferably, the lower end of the feed bin 101 is in the shape of an isosceles trapezoid and the opening becomes smaller as it goes downwards. The push hopper 203 slides upward along the smallest opening below the feed bin 101 in contact with the inner wall of the feed bin 101. The upper end face of the push hopper 203 is an inclined surface with an arc-shaped groove on it. The rubber counterweight 102 is snap-fitted into the arc groove and can only accommodate one.

[0048] More preferably, during the rising process of the push hopper 203 , the randomly arranged rubber weights 102 in the push hopper 203 are arranged linearly along the arc groove. When the lower end of the push hopper 203 rises to the position of the outlet 1011 , the rubber weights 102 slide out of the outlet 1011 and are sleeved on the guide shaft 201 .

[0049] More preferably, the outer wall of the balance oil pipe 3021 is connected to an indicator plate 3022 , and the inner wall of the indicator plate 3022 is sealed and slidably provided with an oil separator, one end of the oil separator passes through the indicator plate 3022 and is connected to a pointer 3024 .

[0050] The probe 302 is driven by a hydraulic cylinder to slide in the detection frame 301 . When more hydraulic oil enters the probe 302 , the probe 302 extends downwards further. A ball 3025 is provided at the end of the probe 302 .

[0051] Preferably, the ball 3025 is a carbide ball, and the rubber hardness can be determined by the depth of the sinking displacement of the ball 3025 after contacting the rubber counterweight 102. Through holes are respectively opened on the upper end surface of the conveying tube 200, so that the detection frame 301 and the probe 302 can slide up and down along the through holes. A speed sensor is provided on the inner wall of the through hole where the probe 302 slides. When the speed of the probe 302 exceeds the monitoring threshold, the speed is recorded. At the same time, the greater the elasticity of the rubber counterweight 102, the greater the rebound force, and the faster the rebound speed of the detection frame 301. Whether the elasticity of the rubber counterweight 102 is qualified is judged according to the rebound speed of the detection frame 301.

[0052] Furthermore, since the total amount of hydraulic oil in the balancing oil pipe 3021 is constant, when the hardness of the rubber counterweight blocks 102 contacting on both sides of the detection frame 301 is inconsistent, the two probes 302 in contact therewith sink to different depths, so that the amount of hydraulic oil entering on both sides is different, and the hydraulic oil and oil separator in the balancing oil pipe 3021 lose balance and flow, thereby driving the pointer 3024 to move and move in the direction of smaller hardness, so as to detect whether the hardness of each area of ​​the rubber counterweight block 102 is consistent.

[0053] Among them, in this embodiment, the linkage component 300 is a spring, and the spring is pushed by the operator to drive the detection frame 301 to move downward, and the material moving claw 202 moves downward to separate from the rubber counterweight block 102. At the same time, the probe 302 can contact the surface of the rubber counterweight block 102 and press down to detect the hardness. The operator uses the same force each time to press the detection frame 301 down to the limit distance and then releases it. The spring force plus the elastic force of the rubber counterweight block 102 makes the detection frame 301 rebound quickly, and the rebound speed is detected and recorded by the speed sensor in the through hole.

[0054] Preferably, as a preferred solution of this embodiment, the detection frame 301 can be set horizontally to offset the influence of gravity on the detection frame 301, improve the measurement accuracy of the rebound speed and thus improve the elasticity measurement accuracy. The detection frame 301 can also be set vertically, and a spring with an elastic modulus that offsets the gravity of the detection frame 301 itself is selected to offset the influence of gravity.

[0055] In summary, when in use, the user pushes the push hopper 203 to slide up and down along the feed bin 101. During the rising process of the push hopper 203, the end faces on both sides slide up and down in accordance with the feed bin 101. The rubber counterweights 102 with a small angle deviation from the inclined surface of the feed bin 101 are embedded in the arc groove and arranged linearly. The rubber counterweights 102 are lifted up and slide into the conveying pipe 200 at the outlet 1011, and slowly slide down along the guide shaft 201, thereby realizing the sequential falling transportation of the rubber counterweights 102.

[0056] When the rubber counterweight 102 descends along the guide shaft 201, the operator pushes the detection frame 301 to move downward, and the material moving claw 202 moves downward and separates from the rubber counterweight 102. At the same time, the probe 302 can contact the surface of the rubber counterweight 102 and press down to detect the hardness. The hardness is judged according to the sinking depth of the probe 302 and the ball 3025, and whether the hardness of the rubber counterweight 102 at both ends of the detection frame 301 is consistent is judged according to the position of the pointer 3024. The operator uses the same force to press the detection frame 301 to the limit distance each time and then releases it. The spring force plus the elastic force of the rubber counterweight 102 makes the detection frame 301 rebound quickly. At this time, the rebound speed is recorded by the speed sensor, and the elasticity is determined according to the rebound speed, thereby realizing the assembly line hardness and elasticity detection of the rubber counterweight 102. The operation is simple and the detection efficiency is fast. At the same time, the regional hardness difference at both ends of the rubber counterweight 102 can also be measured, thereby ensuring the uniformity of product hardness, improving product quality, and preventing the occurrence of local wear.

[0057] Example 2

[0058] Reference Figure 1 to Figure 9 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but is different in that the linkage assembly 300 facilitates the operation of the operator, simplifies the operation steps, ensures that the force of each hardness measurement is consistent, ensures that the measurement results are consistent each time, and reduces the measurement error.

[0059] Specifically, the linkage assembly 300 includes a guide rail 303 disposed on the inner wall of the conveying pipe 200 , a movable slider 3011 and a fixed slider 3012 slidably disposed on the inner wall of the guide rail 303 , and a cylinder 3013 is parallelly disposed on the inner wall of the guide rail 303 .

[0060] The fixed sliding block 3012 is slidably sleeved on the outer wall of the cylinder 3013 , and the outer wall of the cylinder 3013 is also sleeved with a first elastic member 3014 , and two ends of the first elastic member 3014 are respectively connected to the fixed sliding block 3012 and the inner wall of the guide rail 303 .

[0061] Among them, the first elastic member 3014 is a spring, which pushes the fixed sliding block 3012 away from the inner wall of the guide rail 303 and keeps it stationary. Two parallel guide rails 303 are provided, and the movable sliding block 3011 and the fixed sliding block 3012 are respectively slidably arranged on the two guide rails 303, and the movable sliding block 3011 and the fixed sliding block 3012 have the same horizontal height.

[0062] More preferably, a positioning hole 3015 is provided in an array in the middle of the two guide rails 303 , and a reset block 3016 is detachably provided on the positioning hole 3015 , and a sliding inclined surface 3017 is provided on one end of the reset block 3016 close to the fixed sliding block 3012 .

[0063] Furthermore, a through slot 3018 is provided in the middle of the other end surface of the reset block 3016 , and a lever 3039 is provided on the outer wall of the movable slider 3011 , and the lever 3039 slides through the through slot 3018 .

[0064] Among them, a stopper 3019 is slidably provided at one end of the fixed sliding block 3012 close to the movable sliding block 3011. The stopper 3019 is slidably arranged in the fixed sliding block 3012 through a spring. The stopper 3019 slides with the slip slope 3017. When the stopper 3019 moves, it slides along the slip slope 3017 and disengages from the lever 3039.

[0065] Preferably, the lever 3039 is cylindrical and has a rounded end face, and the end of the stopper 3019 close to the slip slope 3017 has an angle, so that the lever 3039 can slide along the angle of the stopper 3019, or it can fit with the right-angle surface of the stopper 3019 and drive it to move together.

[0066] Among them, each positioning hole 3015 is distributed at equal intervals, and the sliding slope 3017 is detachably arranged in each positioning hole 3015 by bolts, so as to adjust the stroke of the movable slider 3011. The size of the stopper 3019 is larger than the width of the through groove 3018. Therefore, when the lever 3039 slides through the through groove 3018, the stopper 3019 shrinks and slides along the sliding slope 3017 into the fixed slider 3012 and disengages from the lever 3039.

[0067] More preferably, in this embodiment, one end of the movable slider 3011 slides through the conveying pipe 200 and is provided with a handle, and the operator controls the movement of the handle to realize the movement of the movable slider 3011, and the outer wall of the fixed slider 3012 is connected to the detection frame 301 and moves together with it.

[0068] In summary, when in use, the operator only needs to move the handle to drive the movable slider 3011 to move upward along the guide rail 303. At this time, the lever 3039 slides along the surface of the block 3019, and the block 3019 retracts and compresses the spring so that the lever 3039 continues to slide and disengage along the inclined surface of the block 3019. At this time, the block 3019 is fully extended and reset under the push of the spring. At this time, the operator pulls the handle back in the opposite direction, and the lever 3039 fits the right-angle surface of the block 3019 and drives it to move together, so that the movable slider 3011 moves with the fixed slider 3012.

[0069] At the same time, the detection frame 301 connected to the fixed slider 3012 moves in the opposite direction and makes the probe 302 contact with the surface of the rubber counterweight 102 for measurement. When the handle and the movable slider 3011 move to the slip slope 3017, the maximum measurement stroke is reached. At this time, the force applied to the probe 302 is the largest, and then the lever 3039 slides inward along the groove 3018, and the stopper 3019 slides along the slip slope 3017 and disengages from the lever 3039, so that the fixed slider 3012 is quickly reset under the push of the first elastic member 3014, and the rebound speed is measured at the same time. Since the rebound of the fixed slider 3012 occurs at the moment of slipping, it takes a very short time to release the lock between the stopper 3019 and the lever 3039, so the measurement error is small, and since the maximum stroke of the probe 302 is constant each time, the hardness measurement force applied is consistent, thereby ensuring that the measurement results tend to be consistent each time and reducing the measurement error.

[0070] Example 3

[0071] Reference Figure 1-Figure 9 , which is the third embodiment of the present invention, is based on the previous embodiment, but differs in that the transportation, detection and feeding of the rubber weight block 102 are synchronized, thereby realizing streamlined detection, which improves the hardness and elasticity detection efficiency while ensuring measurement accuracy.

[0072] Specifically, one end of the movable slider 3011 is connected to the material moving claw 202 , and an arc frame 2021 is provided on the upper end of the material moving claw 202 , and the arc frame 2021 is movably fitted to the outer wall of the rubber counterweight 102 .

[0073] A conveying groove 2022 is opened on the inner wall of the bottom of the conveying pipe 200, and the end of the material moving claw 202 away from the arc frame 2021 slides through the conveying groove 2022 and slides along the conveying groove 2022. A connecting frame 2023 is also provided on the end of the material moving claw 202 away from the arc frame 2021.

[0074] Furthermore, a material shifting plate 2024 is provided on the lower end surface of the connecting frame 2023 , a roundabout 2025 is provided at the center of the material shifting plate 2024 , a limit frame 2026 is movably sleeved on the outer wall of the roundabout 2025 , and slide bars 2027 are provided on the outer walls on both sides of the limit frame 2026 , and the slide bars 2027 slide through the shell 100 .

[0075] The roundabout 2025 is a rectangle, and the limit frame 2026 is a vertically placed rectangle with a width twice that of the roundabout 2025 , so that the roundabout 2025 can slide up and down along the limit frame 2026 and can drive the limit frame 2026 to slide left and right.

[0076] Furthermore, an annular groove 2028 is provided on the outer wall of the material moving plate 2024, a waist-shaped block 2029 is provided in the annular groove 2028, a material moving column 2031 is provided in the end face array of the waist-shaped block 2029, and a rotating shaft 2032 is slidably provided between the annular groove 2028 and the waist-shaped block 2029.

[0077] Among them, a rotating disk 2033 is fixedly sleeved on the outer wall of the rotating shaft 2032, and blades 2035 are arranged in a circular array on the outer wall of the rotating disk 2033. The blades 2035 can be sequentially embedded between each material transfer column 2031, so that the rotating disk 2033 can circulate along the waist-shaped gap between the annular groove 2028 and the waist-shaped block 2029.

[0078] Among them, the annular groove 2028 is a hollow waist-shaped groove and forms a waist-shaped gap with the outer wall of the waist-shaped block 2029. The rotating shaft 2032 can rotate along the waist-shaped gap while rotating. At the same time, the blades 2035 are engaged and disengaged with the gaps between each material transfer column 2031 in turn, so that the turntable 2033 rotates.

[0079] Preferably, one end of the rotating shaft 2032 that rotates and passes through the conveying pipe 200 is connected to a driving motor, so that when the rotating shaft 2032 rotates, the material moving plate 2024 is driven to rotate circularly, and the circular rotation of the material moving plate 2024 drives the linkage assembly 300 to rotate circularly, so that when the linkage assembly 300 moves up and down, the loading and unloading of the hardness and elasticity tests are realized. When the linkage assembly 300 moves left and right, the rubber counterweight block 102 is transported downward one grid through the material moving claw 202, and the next hardness and elasticity test is carried out. The average value of three tests is taken as the final data.

[0080] More preferably, the outer wall of the rotating shaft 2032 is also sleeved with an eccentric cam, and a landing gear is movably sleeved outside the eccentric cam, and the landing gear is connected to the pushing hopper 203, so that every time the material moving claw 202 removes a rubber counterweight block 102, the pushing hopper 203 will replenish a rubber counterweight block 102 into the outlet 1011, thereby realizing streamlined detection.

[0081] In summary, when in use, the driving motor rotates and drives the rotating shaft 2032 to rotate through the output end. The eccentric cam of the rotating shaft 2032 rotates to drive the landing gear to move back and forth up and down, and makes the push hopper 203 move up and down in a cycle, and the rubber counterweight block 102 is put into the outlet 1011, thereby realizing the synchronization of detection and automatic feeding, and improving the detection efficiency.

[0082] At the same time, the rotation of the rotating shaft 2032 drives the turntable 2033 and the blade 2035 to rotate, and moves each material transfer column 2031, so that the rotating shaft 2032 produces relative sliding in the gap formed by the turntable 2033 and the annular groove 2028, and the material transfer plate 2024 rotates reciprocatingly, and the linkage assembly 300 is driven to rotate cyclically through the circular rotation of the material transfer plate 2024, so that when the linkage assembly 300 moves up and down, the loading and unloading of the hardness and elasticity tests are realized. When the linkage assembly 300 moves left and right, the rubber counterweight block 102 is transported downward by one grid through the material transfer claw 202, and the hardness and elasticity tests are repeated. The average value of the three tests is taken as the final data, thereby improving the measurement accuracy. At the same time, the elasticity and hardness tests are carried out synchronously during the transportation of the rubber counterweight block 102, which improves the efficiency while ensuring the measurement accuracy and realizes streamlined testing.
