Description

Technical Field

[0001] This invention relates to the field of testing equipment, and more particularly to a test feeler gauge for a capping claw used in screening for copper sleeve wear. Background Technology

[0002] Capping claw structures are widely used in bottle cap tightening equipment. They typically achieve bottle cap clamping and tightening through the rotational engagement between the capping claw and an internal copper sleeve. During long-term operation, the copper sleeve inside the capping claw is subjected to periodic rotational friction and impact loads, causing gradual wear on the inner wall of the sleeve. This leads to an increase in the clearance between the capping claw and the copper sleeve, resulting in wobbling during capping claw movement. This affects the accuracy of bottle cap tightening and the stability of equipment operation. Therefore, during equipment maintenance, it is necessary to inspect the clearance between the capping claw and the copper sleeve to determine the degree of wear on the copper sleeve and to replace it promptly.

[0003] In existing technologies, feeler gauges are typically used to inspect the gaps between components. For example, patent CN214333569U discloses a feeler gauge that uses multiple measuring pieces inserted into the gap to be inspected to measure the gap size. This type of feeler gauge can meet the inspection requirements of ordinary planar gaps. However, since the copper sleeve inside the cap claw is usually located in a ring-shaped installation position, its inspection gap is distributed along the circumference of the copper sleeve. When using a traditional feeler gauge, it is difficult for the inspector to ensure that the feeler piece and the copper sleeve maintain a stable position. The inspection position is easily shifted due to changes in the insertion angle, making it impossible to inspect gaps along the circumference of the copper sleeve. The wear condition of the area is continuously screened. Meanwhile, in existing multi-piece feeler gauges, when one measuring piece is removed for testing, the remaining pieces are prone to partial suspension, which can lead to bending and deformation over long-term use, reducing the positional accuracy of the measuring pieces when inserted into the gap. Furthermore, during repeated rotation or adjustment of the multi-piece measuring structure, friction and wear easily occur between the components, gradually increasing the installation gap and causing the measuring pieces to loosen, affecting the testing stability and the lifespan of the device. Therefore, there is an urgent need for a copper sleeve wear screening feeler gauge that can achieve accurate detection positioning and improve the stability of the feeler pieces during use. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a test feeler gauge for capping claws in copper sleeve wear screening.

[0005] To achieve the above objectives, the technical solution adopted by this invention is as follows: a test feeler gauge for capping claws in copper sleeve wear screening, comprising a mounting shell, a copper sleeve to be tested, and a capping claw to be tested. A set of feelers is provided on both sides of the mounting shell. Each set of feelers consists of multiple feelers of varying thicknesses. One end of each feeler is rotatably connected to a connecting piece via a damping hinge. The end of each connecting piece away from the feeler is rotatably connected to a fixing piece via a damping hinge. Each feeler has a graduation in its center. A fixing cylinder is rotatably connected through and to the center of each fixing piece. Uniformly distributed limiting grooves are formed on the outer periphery of each fixing cylinder. The top of each groove extends through the top of the fixed cylinder. Multiple graphite rings are slidably connected to the outer periphery of the fixed cylinder. Evenly distributed sliders are fixedly connected to the inner side of each graphite ring. The sliders are slidably connected to the inner side of the limiting groove. An installation port is provided between the upper and lower fixed pieces. The graphite rings are rotatably connected to the inner side of the installation port. A fixed seat is installed at one end of the inner side of the mounting shell. A set of support plates are slidably connected to both sides of the fixed seat. Each support plate corresponds to a plug piece. An elastic element is fixedly connected to the side of the support plate away from the plug piece. The end of the elastic element away from the support plate is installed inside the fixed seat.

[0006] Preferably, the fixing cylinders all penetrate through both sides of the middle of one end of the mounting shell, and the upper and lower parts of the fixing cylinders are provided with end caps.

[0007] Preferably, each of the two ends of the rotating end cap is fixedly connected to a threaded connecting sleeve, and the rotating end caps are all located on the upper and lower parts of the mounting shell.

[0008] Preferably, each of the fixed cylinders is provided with a slider, and the upper and lower ends of the slider are engaged with the middle of the inner side of the fixed piece.

[0009] Preferably, the upper and lower ends of the fixed cylinder are provided with threaded connection grooves, and the threaded connection sleeves are threadedly connected to the inner side of the threaded connection grooves.

[0010] Preferably, the mounting shell has symmetrically distributed reserved openings on both sides.

[0011] Preferably, a buckle is provided in the middle of one side of the mounting shell, and a rotating block is rotatably connected to the bottom side of the buckle via a damping rod. A threaded post is fixedly connected to the middle of the end of the rotating block away from the buckle.

[0012] Preferably, the rotating block is threadedly connected to a connecting post via a threaded post, and a retaining post is rotatably connected to the end of the connecting post away from the rotating block.

[0013] Preferably, the copper sleeve to be tested is located in the middle of the cap claw to be tested.

[0014] Preferably, the locking pin is installed inside the copper sleeve to be tested, and the plug is used to insert into the gap between the copper sleeve to be tested and the capping claw to be tested for detection.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention features multiple sets of plugs of varying thicknesses symmetrically arranged on both sides of the mounting housing. During testing, plugs of corresponding specifications on both sides can be simultaneously inserted into the mating gap between the copper sleeve to be tested and the screw cap claw, achieving simultaneous testing of points on both sides. The plugs have built-in scale markings, allowing for intuitive reading and control of the insertion depth of the plugs on both sides during testing. This ensures that the insertion depth on both sides remains consistent during full rotation testing, effectively avoiding offset errors and result deviations caused by unilateral testing and uneven depths, and significantly improving the accuracy and efficiency of wear screening.

[0016] 2. The device of the present invention consists of a positioning assembly composed of a buckle, a rotating block, a threaded post, a connecting post, and a locking post. During testing, the locking post is inserted into the copper sleeve to be tested, which achieves coaxial relative positioning of the feeler gauge and the copper sleeve to be tested, providing a unified testing benchmark for both sides of the feeler gauge. During the circumferential rotation screening process, the coaxial positioning structure can always maintain a stable distance between the center of the feeler gauge and the copper sleeve, ensuring that the detection positions on both sides are symmetrically corresponding, avoiding misalignment of detection points and deviation of gap measurement benchmark due to feeler gauge offset, and effectively ensuring the consistency and reliability of the circumferential full-range detection.

[0017] 3. This invention features an independent support plate and elastic element for each feeler gauge. When a single feeler gauge is removed for use, the corresponding support plate automatically pops out under the action of the elastic element, providing stable support for the remaining unused feelers. This solves the problem of some feelers being suspended and easily bent and deformed in traditional multi-blade feeler gauges, ensuring the flatness of the feelers over a long period and maintaining the detection accuracy during repeated use. At the same time, the support plate has a rounded chamfered edge structure, allowing the support plate to be smoothly retracted and reset when the feeler is returned to its original position, making storage and operation convenient and efficient.

[0018] 4. This invention sets a graphite ring between adjacent fixed plates and achieves circumferential positioning through the cooperation of a slider and a limiting groove. During the adjustment of the plug rotation, the self-lubricating properties of graphite can be used to reduce the frictional resistance between the fixed plates, avoiding the problem of increased gap and loose plug installation caused by wear of the fixed plates after long-term use, effectively improving the overall structural stability of the device. With the quick-release structure of the screw end cap, threaded connecting sleeve and threaded connecting groove, the graphite ring can be quickly disassembled and replaced after wear, reducing maintenance difficulty and extending the overall service life of the device.

[0019] 5. The present invention employs a rotating connection structure between the plug and the fixing plate using a connecting plate and a damping rod. This allows the plug to rotate around the connecting end to adjust its angle as needed, flexibly adapting to the annular gaps at different positions around the copper sleeve, effectively reducing the difficulty of insertion and alignment in narrow gaps. At the same time, the damping structure can limit the angle of the adjusted plug, preventing the plug from shifting or shaking during circumferential rotation screening. It can also buffer the rigid squeezing force during testing, reducing plug deformation damage and significantly improving the convenience of testing operations and the durability of the plug.

[0020] 6. The clamping post and connecting post of this invention adopt a threaded detachable structure, which can quickly replace the corresponding clamping post according to the copper sleeve to be tested with different inner diameters. It can adapt to the copper sleeve wear screening needs of various models of capping claws, and the device has excellent versatility. At the same time, the positioning component can be folded and stored in the buckle on the side of the mounting shell through the damping rotation structure. With the reserved openings on both sides of the mounting shell, the plug can be quickly put in and taken out. The overall structure is compact and highly integrated, which is convenient for on-site operation and maintenance, and daily storage and management. Attached Figure Description

[0023] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] like Figures 1-8 The diagram shows a test feeler gauge for capping claws used in copper sleeve wear screening. It includes a mounting housing 101, a copper sleeve 2 to be tested, and capping claws 3 to be tested. A set of feelers 103 is provided on both sides of the mounting housing 101. Each set of feelers 103 consists of multiple feelers 103 of varying thicknesses. One end of each feeler 103 is rotatably connected to a connecting piece 105 via a damping hinge. The end of the connecting piece 105 away from the feeler 103 is rotatably connected to a fixing piece 122 via a damping hinge. Each feeler 103 has a graduation 104 in its center. Symmetrically distributed pre-drilled openings 102 are provided on both sides of the mounting housing 101. A buckle 107 is provided in the middle of one side of the housing 101. A rotating block 121 is rotatably connected to the bottom side of the buckle 107 via a damping rod. A threaded post 114 is fixedly connected to the middle of the end of the rotating block 121 away from the buckle 107. A connecting post 109 is threadedly connected to the rotating block 121 via the threaded post 114. A locking post 110 is rotatably connected to the end of the connecting post 109 away from the rotating block 121. The copper sleeve 2 to be tested is located in the middle of the capping claw 3 to be tested. The locking post 110 is installed inside the copper sleeve 2 to be tested. A plug 103 is used to be inserted into the gap between the copper sleeve 2 to be tested and the capping claw 3 to be tested for detection. Furthermore, in specific implementation, the mounting housing 101 is provided with an installation space for accommodating the plug 103. Multiple plugs 103 of different thicknesses are arranged and installed sequentially inside the mounting housing 101, so that plugs 103 of different thicknesses can be taken out independently for testing. The end of the plug 103 away from the fixing piece 122 extends out of the mounting housing 101 and is put in and taken out through the reserved opening 102. The connecting piece 105 is set between the plug 103 and the fixing piece 122 to realize the flexible connection between the plug 103 and the fixing piece 122, so that the plug 103 can bend to a certain extent when inserted into the gap between the copper sleeve 2 to be tested and the cap claw 3 to be tested, so that the plug 103 can adapt to the testing requirements of different angle positions, while avoiding the plug 103 from breaking when subjected to rigid compression.

[0025] The fixing plate 122 is rotatably connected to the fixing cylinder 120 through the middle. The fixing cylinder 120 is provided with uniformly distributed limiting grooves 118 on its outer periphery. The top of the limiting grooves 118 passes through the top of the fixing cylinder 120. Multiple graphite rings 115 are slidably connected to the outer periphery of the fixing cylinder 120. The inner side of the graphite rings 115 is fixedly connected to uniformly distributed sliders 116. The sliders 116 are slidably connected to the inner side of the limiting grooves 118. The upper and lower fixing plates 122 are provided with mounting openings 117. The graphite rings 115 are rotatably connected to the inner side of the mounting openings 117. The mounting openings 117 are large-angle conical cavities. The graphite rings 115 correspond to the mounting openings 117. Furthermore, in specific implementation, the fixing cylinder 120 is used to install and support the fixing plate 122 and the graphite ring 115. The fixing plate 122 can rotate around the fixing cylinder 120, so that the plug 103 installed on the fixing plate 122 can rotate and adjust synchronously. The graphite ring 115 is set between the upper and lower adjacent fixing plates 122 and can rotate inside the mounting opening 117. The low friction characteristics of the graphite ring 115 reduce the rotational resistance between the fixing plates 122, avoid the fixing plates 122 from wearing due to long-term mutual friction, and thus prevent the installation position of the plug 103 from shifting. At the same time, the slider 116 is slidably connected along the limiting groove 118, so that the graphite ring 115 can maintain circumferential limitation and prevent the graphite ring 115 from shifting during rotation.

[0026] Among them, the fixing cylinder 120 passes through both sides of the middle of one end of the mounting shell 101. The upper and lower parts of the fixing cylinder 120 are provided with screw end caps 106. The ends of the screw end caps 106 that are close to each other are fixedly connected with threaded connecting sleeves 111. The screw end caps 106 are provided in the upper and lower parts of the mounting shell 101. The inner side of the fixing cylinder 120 is provided with sliders 116. The upper and lower ends of the sliders 116 are engaged in the middle of the inner side of the fixing piece 122. The upper and lower ends of the fixing cylinder 120 are provided with threaded connecting grooves 119. The threaded connecting sleeves 111 are threadedly connected to the inner side of the threaded connecting grooves 119. Furthermore, in specific implementation, the fixed cylinder 120 is installed through the side wall of the mounting shell 101 and is limited and fixed by the screw end cap 106. The screw end cap 106 is installed on the upper and lower sides of the fixed cylinder 120 respectively, and the screw end cap 106 provides axial constraint for the fixed cylinder 120 and the internal mounting structure. The threaded connecting sleeve 111 on the screw end cap 106 is connected to the threaded connecting groove 119 on the fixed cylinder 120, so that the screw end cap 106 can be quickly disassembled and installed. When the graphite ring 115 wears out after long-term use, the graphite ring 115 can be removed and replaced by disassembling the screw end cap 106, which improves the convenience of device maintenance. At the same time, the threaded connection structure can ensure the stability of the screw end cap 106 after installation, and avoid the screw end cap 106 from loosening during the detection process, which would affect the detection accuracy of the plug 103.

[0027] Among them, a fixed base 108 is installed on one end of the inner side of the mounting shell 101. A set of support plates 112 are slidably connected to both sides of the fixed base 108. Each support plate 112 corresponds to a plug 103. An elastic member 113 is fixedly connected to the side of the support plate 112 away from the plug 103. The end of the elastic member 113 away from the support plate 112 is installed inside the fixed base 108. Furthermore, in specific implementation, the fixing seat 108 is set inside the mounting shell 101 to limit the installation of the support plate 112 and the elastic member 113. The support plate 112 is set for different positions of the plug pieces 103, so that each plug piece 103 has an independent support structure. When the plug piece 103 is installed inside the mounting shell 101, the plug piece 103 can limit the support plate 112 at the corresponding position, so that the support plate 112 remains in a contracted state. When a plug piece 103 is removed for testing, the corresponding support plate 112 loses the restriction of the plug piece 103 and moves outward under the elastic action of the elastic member 113, providing auxiliary support for the adjacent plug pieces 103 and preventing the remaining plug pieces 103 from bending due to local loss of support. At the same time, the edge of the support plate 112 is provided with rounded chamfers, so that when the plug piece 103 is reinstalled, it can push the support plate 112 to smoothly retract into the fixing seat 108, realizing the automatic reset of the support plate 112.

[0028] Working principle: In practical use, the gap between the copper sleeve 2 and the capping claw 3 can be detected by using a feeler gauge. Specifically, the plugs 103 on both sides can be removed through the pre-drilled opening 102. Simultaneously, the threaded post 114 and the rotating block 121 can be pulled downwards. When rotated to its limit, the rotating block 121 rotates 90 degrees, making the rotating block 121 and the threaded post 114 perpendicular to the mounting shell 101. The damping rod between the rotating block 121 and the latch 107 allows for the control of the rotating block 121. The limit is set, and then the connecting post 109 can be connected through the threaded post 114. Then, a suitable clamping post 110 can be selected according to the size of the copper sleeve 2 to be tested. The clamping post 110 is fitted onto the bottom of the connecting post 109, and then the clamping post 110 is inserted into the inside of the copper sleeve 2 to achieve relative positioning between the feeler gauge and the copper sleeve 2. This is beneficial for subsequent wear screening and testing of the copper sleeve 2. During testing, the thinnest feeler plate 103 can be selected first for testing. The connecting piece 105 allows the feeler plate 103 to be easily bent downwards, which is beneficial for practical application. In use, two sets of inserts 103 on both sides can be simultaneously inserted into the gap between the copper sleeve 2 to be tested and the capping claw 3 during testing. The inserts 103 are made of plastic, making them easy to deform and insert. During testing, the depth of insertion of the inserts 103 can be quickly identified by the scale 104 on the inserts 103, which is beneficial for wear detection. During testing, the rotating connection between the connecting post 109 and the locking post 110 allows for easy rotation of the test gauge, enabling comprehensive testing of the circumference of the copper sleeve 2 to be tested. During this process, the scale 104 can help people observe and avoid deviations in the test results caused by inconsistent insertion depths on both sides during the full circle test. During the rotation, the cooperation between the locking post 110 and the inner wall of the copper sleeve 2 under test can maintain the coaxial positioning of the connecting post 109 and the copper sleeve 2 under test, so that the plug 103 can rotate stably around the center of the copper sleeve 2 under test. This avoids changes in the contact position between the plug 103 and the copper sleeve 2 and the capping claw 3 under test due to the deviation of the test gauge, thus improving the stability of the test process.Meanwhile, since both sides of the plug 103 are provided with plugs 103 of corresponding thickness specifications, the inspector can gradually increase the thickness of the plug 103 to screen the gap according to the actual inspection situation. When a plug 103 of a certain thickness cannot be inserted into the gap or the insertion resistance increases significantly, it can be determined that the gap between the copper sleeve 2 to be tested and the capping claw 3 to be tested is within the corresponding range, thereby realizing a rapid judgment of the wear degree of the copper sleeve. During the inspection process, when it is necessary to remove the plug 103 of the corresponding thickness for gap inspection, after the plug 103 is removed from the inside of the mounting shell 101, the support plate 112 at the corresponding position loses the limiting function of the plug 103. At this time, the support plate Under the elastic restoring force of the elastic element 113, 112 moves outward and pops out, so that the support plate 112 supports the adjacent plug 103, preventing the remaining unused plugs 103 from bending and deforming due to one end being suspended, thereby ensuring that each plug 103 always remains in a straight state and improving the stability of the plugs 103 during subsequent insertion and testing; at the same time, the support plate 112 is provided with a rounded chamfer structure on its edge. When the plug 103 needs to be reinstalled into the mounting shell 101 after testing, the plug 103 can push the support plate 112 to retract along the inner side of the fixing seat 108, so that the support plate 112 automatically resets without additional operation, improving the stability of the plug 103. For ease of storage, during long-term use of the feeler gauge, the fixed plates 122 need to rotate relative to each other. The graphite ring 115 positioned between the fixed plates 122 utilizes the lubricating properties of the graphite material to reduce frictional resistance between adjacent fixed plates 122, preventing increased gaps due to frictional wear during long-term rotation and thus avoiding loosening of the feeler plate 103's mounting position. This improves the overall stability of the feeler gauge structure. Simultaneously, the graphite ring 115 is mounted on the outer periphery of the fixed cylinder 120 through the cooperation of the slider 116 and the limiting groove 118, ensuring stable positioning of the graphite ring 115. It is also connected to the threaded sleeve 111. The threaded connection groove 119 enables the connection and fixation of the end cap 106 and the fixed cylinder 120. When the graphite ring 115 wears out, it can be quickly replaced by disassembling the end cap 106, improving the convenience of device maintenance. After the test is completed, the tester can remove the locking post 110 from the copper sleeve 2 under test and separate the connecting post 109 from the threaded post 114. Through the above process, the fitting clearance between the copper sleeve 2 under test and the capping claw 3 under test can be quickly detected using the plugs 103 of different thicknesses. The wear degree of the copper sleeve can be judged by the scale 104 on the plug 103, realizing the rapid screening of the wear condition of the copper sleeve for the capping claw.
