Description

Technical Field

[0001] The invention relates to the technical field of counterweight detection, in particular to a processing accuracy detection device for a rubber counterweight. Background Art

[0002] Rubber counterweights are important components used in car air conditioners to reduce vibrations of vibrating components or components connected to vibrating components (such as compressor copper tubes). The main function of the rubber counterweights on the copper tubes of car air-conditioning compressors is to reduce vibration and noise. The air-conditioning compressor will generate vibrations and noise when working. The rubber counterweights can effectively absorb and attenuate these vibrations through their elasticity and mass, thereby reducing noise. Copper tubes may resonate at certain frequencies, resulting in increased noise and component wear. Rubber counterweights can change the vibration characteristics of the copper tubes, 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 tubes play the role of transmitting refrigerant in the car air-conditioning system, vibration and impact may cause fatigue and damage to the copper tubes. Rubber counterweights can provide additional support and protection, reduce the stress and wear of the copper tubes, and extend their service life. Finally, by reducing vibrations, noise and resonance, the rubber counterweights can improve the stability and reliability of the entire air-conditioning system.

[0003] The existing Chinese patent with authorization announcement number CN205315611U discloses an air conditioner counterweight, which includes a circular rubber block with an opening on the side wall, a center wire hole arranged on the rubber block, and a buckling device arranged on the opening of the side wall of the rubber block; a slit is arranged on the rubber block, extending radially outward from the center wire hole to the outer peripheral surface of the rubber block and penetrating along the axial direction of the rubber block, and the slit separates the rubber block into a left end and a right end; a buckling device made of rubber is used for fixing, and a cable tie fixing method is eliminated. When in use, only the bayonet pin needs to be inserted into the buckled I-shaped slot, which is convenient to use. At the same time, the bayonet pin can also be made of rubber to extend the service life.

[0004] However, the rubber blocks produced by the above technical solution need to undergo secondary processing to ensure that the inner diameter, outer diameter and weight meet the standards. After processing, the rubber counterweights need to be manually inspected, which is highly subjective, has high errors and is inefficient. At the same time, the size and shape of the rubber counterweights directly affect their vibration reduction and noise reduction functions. If the processing accuracy is not high, there will be large differences in the sizes and shapes of different counterweights, resulting in inconsistent vibration reduction effects, which in turn affects the overall performance of the air-conditioning system. At the same time, counterweights with insufficient processing accuracy may encounter difficulties during installation, resulting in poor assembly or assembly failure, which not only affects production efficiency, but may also cause stress concentration in the copper tube and increase its risk of damage. The shape and position of the rubber counterweights have a direct impact on the vibration reduction effect. High-precision processing can ensure that the counterweights are accurately installed in the designed position, thereby maximizing their vibration reduction effects and reducing noise and vibration. Therefore, there is an urgent need for a device that can perform processing accuracy detection on rubber counterweights in batches. Summary of the invention

[0031] 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.

[0032] 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.

[0033] Example 1

[0034] Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, provides a processing accuracy detection device for a rubber counterweight, including a bearing mechanism, a measuring mechanism and a transmission mechanism. The rubber counterweight 104 is transported to the feed chamber 101 through the transmission mechanism, and the outer diameter is accurately detected through the sieve hole 203. The inner diameter is accurately detected by nesting with the step tube 2011 on the measuring wheel 201, thereby realizing streamlined detection, improving detection efficiency, reducing manual operation time, and reducing costs.

[0035] Specifically, it includes a bearing mechanism, including a bracket 100, a feeding chamber 101 and a detection chamber 102 respectively arranged inside the bracket 100, a collecting bin 103 and a rubber weight block 104 arranged at one side of the outlet of the detection chamber 102, the feeding chamber 101 is located above the detection chamber 102, and the rubber weight block 104 enters the detection chamber 102 along the feeding chamber 101 to perform weight and inner diameter detection and slides to the collecting bin 103;

[0036] The measuring mechanism includes a sieve plate 200 slidably disposed between the feed chamber 101 and the detection chamber 102, a measuring wheel 201 rotatably disposed in the detection chamber 102, and a quality inspection channel 202 disposed below the measuring wheel 201. The sieve plate 200 is provided with sieve holes 203, and a rubber counterweight 104 is movably disposed on the inner wall of the sieve hole 203. The quality inspection channel 202 includes a plurality of classification areas 2021, and the classification areas 2021 are bound to the processing accuracy. The measuring wheel 201 drives the rubber counterweight 104 located in the sieve hole 203 to move for detection and is put into different quality inspection channels 202 to determine the processing accuracy according to the detection results.

[0037] The transmission mechanism includes a transmission shaft 300 and a push plate 301 slidably arranged in the collection bin 103. The transmission shaft 300 is coaxially connected to the measuring wheel 201. The transmission shaft 300 also drives the screen plate 200 to oscillate up and down and the push plate 301 to move back and forth. The oscillation frequency of the screen plate 200 and the movement frequency of the push plate 301 are interlocked with the measurement rate of the rubber counterweight 104.

[0038] Among them, the rubber counterweight 104 is a rubber block that is sleeved on the outer wall of the copper tube of the vehicle air conditioner to play a vibration reduction role. It is usually produced by injection molding, and then ground to remove burrs and burrs. At the same time, the diameter of the inner wall of the rubber counterweight 104 is processed to make its inner diameter match the outer diameter of the copper tube of the vehicle air conditioner. At the same time, the weight of the counterweight is also tested to achieve the expected vibration reduction effect.

[0039] Among them, for different types of rubber weights 104, the sieve holes 203 are set according to the standard outer diameter of the rubber weights 104. When the outer diameter of the rubber weight 104 is smaller than the sieve holes 203, it falls directly into the collection bin 103 and is judged as unqualified.

[0040] Preferably, a stepped tube 2011 is provided in a circumferential array on the outer wall of the measuring wheel 201. The stepped tube 2011 is a conical hollow tube. A slide groove 2012 is penetrated through the outer wall of the stepped tube 2011. An adjustment shaft 2013 is slidably provided inside the stepped tube 2011. A ball 2014 is provided between the outer wall of the adjustment shaft 2013 and the slide groove 2012.

[0041] Preferably, the slide groove 2012 is a waist-shaped groove and its direction is along the edge direction of the step tube 2011, so that the ball 2014 slides up and down along the slide groove 2012. When the ball 2014 slides from the larger diameter area of ​​the step tube 2011 to the smaller diameter area, the ball 2014 gradually slides along the slide groove 2012 toward the outer wall of the step tube 2011 and one end passes through the slide groove 2012 to the outside of the step tube 2011.

[0042] The outer wall of the adjusting shaft 2013 is provided with a slot 2026 , the ball 2014 is slidably fitted on the inner wall of the slot 2026 , the outer wall of the adjusting shaft 2013 is also fixedly provided with a boss 2015 , and the outer wall of the adjusting shaft 2013 is also slidably provided with a pressure plate 2016 .

[0043] Among them, a first elastic member 2017 is provided between the pressure plate 2016 and the boss 2015, a connecting rod 2018 is rotatably provided on the outer wall of the adjusting shaft 2013, a limiting groove 2019 is opened on the outer wall of the step tube 2011, a limiting arm 2025 is rotatably provided in the limiting groove 2019, and one end of the limiting arm 2025 is rotatably connected to the connecting rod 2018.

[0044] Among them, the limiting arm 2025 is L-shaped, and one end of the limiting arm 2025 extending to the outer wall of the limiting groove 2019 is opened outward and has a rounded corner, so that the rubber counterweight block 104 can be installed along the limiting arm 2025 to the outer wall of the step tube 2011.

[0045] Furthermore, the end with a larger diameter of the step tube 2011 is connected to the measuring wheel 201, and the end with a smaller diameter is provided with a limiting groove 2019. There are three sets of pressure plates 2016, bosses 2015, slide grooves 2012, and balls 2014, and they are distributed in proportion to the diameter of the step tube 2011.

[0046] Among them, the distances between the three sets of pressure plates 2016, bosses 2015, slide grooves 2012, and balls 2014 are distributed in increasing order and are distributed along the axial direction of the step tube 2011, so that when the adjusting shaft 2013 moves, the three sets of balls 2014 disengage from the limit grooves 2019 in sequence, and the rubber counterweights 104 of different diameters are unlocked and released in turn.

[0047] Furthermore, a connecting seat 2022 is provided at one end of the step pipe 2011, and a cavity 2023 is provided in the connecting seat 2022. The adjusting shaft 2013 slides through the connecting seat 2022 and is provided with a gas tank 2027, and the gas tank 2027 slides freely in the cavity 2023.

[0048] Preferably, one end of the step tube 2011 is connected to the measuring wheel 201 through the connecting seat 2022, the cavity 2023 is filled with lubricating oil, the adjusting shaft 2013 and the connecting seat 2022 are sealed to prevent oil leakage, and the gas tank 2027 is filled with nitrogen, so that the gas tank 2027 has a tendency to float in the cavity 2023. The gas tank 2027 does not fit the inner wall of the cavity 2023, so that the lubricating oil can flow freely in the cavity 2023.

[0049] In summary, when in use, the processed rubber balancing weight 104 is put into the feed cavity 101 and falls onto the sieve plate 200. Some rubber balancing weights 104 with smaller outer diameters fall directly and are judged as unqualified. The rubber balancing weights 104 with qualified outer diameters are engaged with the inner wall of the sieve hole 203. Then, the transmission shaft 300 is rotated to drive the measuring wheel 201 to rotate. When the step tube 2011 on the measuring wheel 201 rotates to the upper end of the measuring wheel 201, in the tangential direction of the measuring wheel 201, the buoyancy of the gas tank 2027 is greater than the sum of the gravity of the gas tank 2027 and the adjusting shaft 2013. The gas tank 2027 slides to the side of the cavity 2023 close to the step tube 2011. As the step tube 2011 rotates horizontally, the limit arm 2025 contacts and inserts into the rubber counterweight 104. The rubber counterweight 104 slides toward the step tube 2011 along the limit arm 2025. The larger the inner diameter of the rubber counterweight 104, the longer the sliding distance along the step tube 2011. When the rubber counterweight 104 cannot be nested on the step tube 2011, the inner diameter is too large or the elasticity is poor, and it automatically falls off in the second half of the rotation, which is considered to be of unqualified quality.

[0050] At the same time, the three limit arms 2025 are squeezed by the rubber balancing weight 104 to rotate inward, and the adjusting shaft 2013 is pushed inward by the connecting rod 2018. After the rubber balancing weight 104 is nested into the outer wall of the step tube 2011, the adjusting shaft 2013 is still automatically reset under the action of buoyancy, thereby driving the boss 2015 and the pressure plate 2016 to move downward. After the pressure plate 2016 contacts the ball 2014, it continues to slide the ball 2014 downward along the slide groove 2012 to the area with a smaller diameter, and then slides out of the step tube 2011 and contacts the inner wall of the rubber balancing weight 104. The ball 2014 at the step tube 2011 with the largest diameter slides out first and limits the rubber balancing weight 104 in this area. The diameter of the rubber balancing weight 104 is divided into: defective products with too small inner diameter, defective products with too small inner diameter and need to be reworked, qualified products, and defective products with too large inner diameter through the three balls 2014.

[0051] In the second half of the rotation of the step tube 2011, the buoyancy of the gas tank 2027 drives the adjusting shaft 2013 to slide slowly in the opposite direction, and at the same time drives the ball 2014 at the smallest diameter of the step tube 2011 to detach from the rubber counterweight 104 and enter the classification area 2021 on the far left of the quality inspection channel 202. Subsequently, in the areas with increasing diameters on the step tube 2011, the balls 2014 detach one by one, and defective products with too small inner diameters, products with too small inner diameters that need to be reworked, qualified products, and defective products with too large inner diameters slide down the four classification areas 2021 from left to right on the quality inspection channel 202 respectively. The user can judge the inner diameter processing accuracy of the rubber counterweight 104 and whether rework is needed based on this. At the same time, the device can perform uninterrupted assembly line testing, thereby improving detection efficiency.

[0052] Example 2

[0053] Reference Figure 1 to Figure 8 , which is the second embodiment of the present invention, is based on the previous embodiment, except that after the inner and outer diameters are detected, the weight of the rubber counterweight 104 is detected, and enters different classification areas 2021, and at the same time, the turntable 3001 and the star-shaped groove 3002 are used to realize the reciprocating oscillation of the screen plate 200 to prevent blockage and improve detection efficiency.

[0054] Specifically, when the rubber counterweight 104 falls along the classification area 2021 and reaches the collecting bin 103, it is mounted on the inner wall of the collecting bin 103. The inner wall of the collecting bin 103 is a thin aluminum alloy, and the surface of the thin aluminum alloy plate is coated with a rubber layer to prevent damage to the product. The rubber counterweight 104 that exceeds the weight has a large kinetic energy after being accelerated by the measuring wheel 201, thereby hitting the inner wall of the thin aluminum alloy with a large force. The aluminum alloy plate is rotatably arranged and swings with different amplitudes as the impact force varies, thereby leading to classification areas 2021 of different weights, and those that meet the weight accuracy requirements are collected in the collecting bin 103.

[0055] The transmission shaft 300 passes through the outer wall of the collection bin 103 and one end of which is provided with a motor 2024 . The other end of the transmission shaft 300 is sleeved with a turntable 3001 , on which a star-shaped slot 3002 is provided.

[0056] Among them, a rotating wheel is slidably provided on the inner wall of the star-shaped groove 3002, and a reciprocating rod 3003 is rotatably provided on the end of the rotating wheel away from the star-shaped groove 3002. A reciprocating groove 3004 is slidably provided on the inner wall of the feed cavity 101, and the screen plate 200 reciprocates and oscillates up and down along the reciprocating groove 3004.

[0057] The sieve plate 200 oscillates up and down, so that the rubber weight block 104 in the feed cavity 101 is continuously moved and embedded into the sieve hole 203, and the rubber weight block 104 with a smaller outer diameter falls directly, thereby improving the detection efficiency.

[0058] Preferably, the reciprocating rod 3003 is fixedly connected to the screen plate 200, and the star-shaped groove 3002 is a five-pointed star groove with a total of 5 high points and 5 low points. When the wheel slides from a high point to a low point in the star-shaped groove 3002, the reciprocating rod 3003 and the wheel move downward, driving the screen plate 200 to descend at the same time.

[0059] Furthermore, the step tube 2011 is also provided with five sets and is distributed close to the five low points. The transmission shaft 300 drives the star-shaped slot 3002 to rotate. When the top of the star-shaped slot 3002 is the lowest point, the reciprocating rod 3003 descends and drives the screen plate 200 to the lowest point. At this time, the step tube 2011 is just released from the rubber counterweight block 104 located on the screen hole 203 and nested to perform inner diameter accuracy detection.

[0060] In this embodiment, the taper of the step tube 2011 is 2°, the inner diameter of the midpoint area of ​​the step tube 2011 is the same as the outer diameter of the automobile air-conditioning copper tube, and the closer the nesting point of the rubber counterweight block 104 is to the midpoint area of ​​the step tube 2011, the higher the inner diameter processing accuracy.

[0061] Preferably, products with unqualified outer diameters fall through the sieve plate 200 and are collected, rubber weight blocks 104 with unqualified inner diameters need to be reworked, products with qualified inner diameters are weight-tested, and products with qualified weights are collected. At this time, the inner diameter, outer diameter, and weight of the rubber weight blocks 104 all meet the processing accuracy requirements and are judged to be qualified products.

[0062] In summary, when in use, as the transmission shaft 300 rotates, the measuring wheel 201 and the turntable 3001 are driven to rotate at the same time, the turntable rolls from the high point to the low point along the star-shaped groove 3002, and drives the reciprocating rod 3003 and the screen plate 200 to move downward. At this time, the step tube 2011 also happens to run to the screen hole 203, and the rubber counterweight block 104 on the screen hole 203 is nested, and the inner diameter is measured.

[0063] At the same time, as the transmission shaft 300 continues to rotate, the step tube 2011 leaves the highest point of the measuring wheel 201. At this time, the rotating wheel also rolls from the low point to the high point along the star-shaped groove 3002. The reciprocating rod 3003 and the screen plate 200 begin to move upward and separate from the step tube 2011, realizing the oscillation of the rubber counterweight block 104 and the precise nesting of the rubber counterweight block 104 for easy observation.

[0064] Example 3

[0065] Reference Figure 1-Figure 8 , which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that after the weight detection is completed, the weight is input into the next area of ​​the collection bin 103 for surface accuracy detection, and at the same time, the anti-blocking block is driven to push the rubber counterweight block 104 to prevent accumulation and blockage, thereby improving detection efficiency.

[0066] Specifically, a landing gear 3005 is further provided on the end surface of the screen plate 200 , and the landing gear 3005 slides through the reciprocating groove 3004 . One end of the landing gear 3005 extending out of the feed chamber 101 is provided with a square plate 3006 , and an inclined groove 3007 is opened on the square plate 3006 .

[0067] Among them, an anti-blocking block is slidably provided on the bottom surface of the collection bin 103, and both ends of the anti-blocking block have rounded corners. A guide shaft 3009 is provided at the lower end of the outer wall of the anti-blocking block. A guide rail 3011 is provided on the inner wall of the collection bin 103, and the guide shaft 3009 is slidably provided on the inner wall of the guide rail 3011.

[0068] Furthermore, a movable column 3012 is also provided on the outer wall of the anti-blocking block, and the movable column 3012 is slidably arranged inside the inclined groove 3007.

[0069] Among them, the inclined groove 3007 is a waist-shaped groove and runs through the square plate 3006. The inclined angle of the inclined groove 3007 is 45°. The guide shaft 3009 is located below the moving column 3012. When the moving column 3012 slides along the inclined groove 3007, the guide shaft 3009 also slides with the guide rail 3011.

[0070] Preferably, the anti-blocking block is an isosceles triangle, and the two hypotenuses are coated with a rubber layer to prevent the rubber counterweight 104 from being damaged. While the anti-blocking block moves along the guide rail 3011, the rubber counterweight 104 that has passed the processing accuracy test is collected and pushed to the next area of ​​the collection bin 103 to prevent the rubber counterweight 104 from blocking the collection bin 103.

[0071] Preferably, after the rubber balancing weight 104 enters the next area of ​​the collection bin 103, the flatness measuring instrument is covered on the surface of the rubber balancing weight 104 through the mobile platform to perform multi-point measurement to determine whether the rubber balancing weight 104 has surface defects and detect tiny protrusions and depressions on the surface.

[0072] In summary, when in use, while the transmission shaft 300 rotates, the reciprocating rod 3003 is driven to move up and down through the turntable 3001, and the square plate 3006 is driven to move up and down through the landing gear 3005, so that the moving column 3012 slides in the inclined groove 3007. When the square plate 3006 slides upward, the moving column 3012 moves to the left side of the inclined groove 3007, and drives the anti-blocking block to slide to the left along the guide rail 3011. When the reciprocating rod 3003 moves downward, the anti-blocking block is driven to slide to the right in the same way. As the anti-blocking block slides back and forth, the qualified rubber counterweight 104 is pushed to the next area of ​​the collection bin 103 by the push of the two hypotenuses of the isosceles triangle, and surface defect measurement is performed to realize assembly line detection, integrate size, weight and surface flatness detection functions, realize comprehensive detection of the rubber counterweight 104, improve detection efficiency, thereby improving the detection accuracy of the rubber counterweight 104, ensuring product quality, improving detection efficiency, reducing manual operation time, and reducing costs.
