Description

Technical Field

[0001] The utility model relates to the field of detection devices and provides a clearance detection device. Background Art

[0002] Measuring axial clearance is a key technology in the maintenance of height adjustment valves. However, due to the inconvenience of maintaining a stable handheld dial indicator and the inability to conveniently pull the height adjustment valve pin, accurate axial clearance measurement is difficult. This not only affects measurement accuracy but also significantly reduces work efficiency. This has become a major technical obstacle in the maintenance of height adjustment valves.

[0003] Currently, there are no specialized measurement devices and methods for measuring the clearance of height adjustment valves, making it difficult to meet the demand for efficient and accurate axial clearance measurement.

DETAILED DESCRIPTION

[0033] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] like Figures 1 to 3 As shown, the embodiment of the present invention provides a clearance detection device, comprising:

[0035] Base 100;

[0036] A positioning assembly is provided on the base 100 and is used to position the detected component on the base 100;

[0037] A clearance detection member 102 is movably mounted on the base 100;

[0038] The movable member 104 is movably mounted on the base 100. The movable member 104 is suitable for driving the detected member to switch between a first position and a second position. In the first position, the clearance detection member 102 abuts against the detected member and the clearance detection member 102 has a first reading. In the second position, the clearance detection member 102 abuts against the detected member and the clearance detection member 102 has a second reading. The difference between the first reading and the second reading is the clearance detection value.

[0039] According to the clearance detection device provided by the embodiment of the present invention, through the precise positioning component and the movable clearance detection part 102, the present invention can achieve high-precision measurement of the clearance of the detected part, meeting the demand for high-precision detection of mechanical parts. The introduction of the movable part 104 enables the detected part to be quickly switched between different positions, thereby simplifying the detection process, shortening the detection time, and improving the detection efficiency. The entire detection device has a compact structure and a reasonable design, making the operation process simple and easy to understand, and reducing the requirements for the operator's skill level. By adjusting the design of the positioning component and the movable part 104, the present invention can be applied to detected parts of different types and sizes, and has a wide range of applicability.

[0040] Please continue to see Figures 1 to 3 The base 100 serves as the basic supporting structure of the entire detection device, ensuring the relative position stability of each component and providing a reliable fixed platform for the detection process.

[0041] The positioning assembly is mounted on the base 100. Its primary function is to precisely position the test component (e.g., a height adjustment valve) on the base 100, preventing displacement during testing and ensuring accurate test results. The positioning assembly may include a clamping mechanism, positioning pins, or other positioning means suitable for the specific test component.

[0042] The clearance detector 102 is a measuring element movably mounted on the base 100, designed to contact the component being tested and measure its clearance. Clearance refers to the maximum allowable gap between the components under specific conditions (e.g., force, rotation, etc.). Clearance detector 102 can utilize a high-precision sensor, micrometer, or other device capable of accurately reading and recording the readings while in contact with the component being tested. For example, a micrometer can be used for clearance detector 102.

[0043] The movable part 104 is also movably mounted on the base 100. The movable part 104 is designed to drive the detected part to switch between a first position and a second position. These two positions represent two different states of the detected part during the detection process, such as a stressed state and an unstressed state. By moving the movable part 104, the state changes of the detected part in actual work can be simulated, thereby more accurately measuring its clearance. In this embodiment, the movable part 104 can use a shift fork, which can be engaged with the pin shaft in the height adjustment valve to drive the pin shaft to switch between the first position and the second position.

[0044] During the testing process, when the tested part is in the first position, the clearance detection member 102 contacts the tested part and records the first reading. When the tested part is moved to the second position by the movable member 104, the clearance detection member 102 contacts the tested part again and records the second reading. The clearance detection value of the tested part can be obtained by calculating the difference between these two readings.

[0045] For example, when the test component is a height adjustment valve, the dial indicator can be reset to zero when the movable member 104 drives the pin in the height adjustment valve to the first position. When the movable member 104 drives the pin in the height adjustment valve to the second position, the dial indicator reading is the axial clearance of the height adjustment valve pin. If the axial clearance of the height adjustment valve pin is 0.4 mm to 0.6 mm, the axial clearance of the height adjustment valve pin is acceptable. Otherwise, the axial clearance of the height adjustment valve pin needs to be recalibrated.

[0046] According to an embodiment of the present invention, the positioning assembly includes a positioning plate 106 . The positioning plate 106 is connected to the base 100 . A first sliding groove 108 is provided on the positioning plate 106 . The movable member 104 is slidably connected to the first sliding groove 108 .

[0047] In one embodiment of the present invention, the design of the positioning assembly is further refined and optimized. The positioning assembly in this embodiment mainly includes a positioning plate 106, which is firmly connected to the base 100 and serves as the main structure for supporting and positioning the detected component.

[0048] The positioning plate 106 is provided with a first slide groove 108. This design allows the movable member 104 to slide smoothly and stably within the first slide groove 108. The movable member 104 is coupled to the first slide groove 108 via some form of connection mechanism (such as a slider, a slide rail, etc.), thereby ensuring smooth and accurate movement of the detected member when the movable member 104 drives the detected member to switch between the first position and the second position.

[0049] By providing the first slide groove 108, the movable part 104 can achieve smooth and vibration-free sliding therein, which helps to reduce errors caused by unstable movement during the detection process and improve the accuracy of the detection results. The customized design of the first slide groove 108 can ensure that the movable part 104 moves according to the predetermined path, so that when the detected part is in the first position and the second position, accurate positioning can be achieved, further improving the accuracy of the detection. The sliding connection between the movable part 104 and the first slide groove 108 makes the operation process more intuitive and simple. The operator only needs to control the sliding of the movable part 104 in the slide groove to achieve the positioning switch of the detected part, reducing the complexity of the operation. The sliding connection design of the first slide groove 108 and the movable part 104 usually has good wear resistance and durability, and can maintain stable performance during long-term use, thereby extending the service life of the device.

[0050] According to an embodiment of the present invention, the positioning assembly further includes a positioning block 110 . The positioning block 110 is connected to the base 100 . The positioning block 110 is also connected to the positioning plate 106 .

[0051] In one embodiment of the present invention, the positioning assembly not only includes the positioning plate 106, but also includes a positioning block 110. The positioning block 110 serves as a bridge connecting the base 100 and the positioning plate 106, and plays an important role in enhancing structural stability and improving positioning accuracy.

[0052] The positioning block 110 is firmly connected to the base 100 through some form of connection mechanism (such as bolts, welding, etc.). At the same time, the positioning block 110 is also connected to the positioning plate 106. This connection can be direct (such as fixing the positioning block 110 and the positioning plate 106 together through bolts) or indirect (such as connecting through other intermediate structures).

[0053] The presence of the positioning block 110 not only enhances the overall structural stability of the positioning assembly, making the connection between the positioning plate 106 and the base 100 more secure, but also improves the positioning accuracy of the detected part. In addition, the positioning block 110 can also serve as a reference point for adjusting the position of the detected part, helping the operator to more accurately locate the detected part in the predetermined position.

[0054] The provision of positioning block 110 makes the overall structure of the positioning assembly more stable, capable of withstanding greater external forces and vibrations, and ensuring the stability and reliability of the positioning assembly during the inspection process. Positioning block 110 ensures the precise positioning of the inspected part during the inspection process, reducing errors caused by inaccurate positioning. The design of positioning block 110 can be customized according to the shape, size, and inspection requirements of the inspected part, making it easier for operators to adjust the position of the inspected part, improving the flexibility and efficiency of the inspection process.

[0055] According to an embodiment of the present invention, a mounting post 112 is provided on the base 100 , and the positioning assembly further includes a clamping structure connected to the mounting post 112 . When the detected component is installed on the base 100 , the clamping structure is suitable for clamping the detected component.

[0056] In one embodiment of the present invention, a mounting post 112 is added to the base 100, and the positioning assembly further includes a clamping structure connected to the mounting post 112. This design is intended to achieve a stable clamping of the detected object through the clamping structure, ensuring that the detected object does not move or loosen during the detection process, thereby improving the accuracy and reliability of the detection.

[0057] Specifically, the mounting post 112 serves as the support structure for the compression structure and is securely connected to the base 100. The compression structure is connected to the mounting post 112 via some form of connection mechanism (e.g., bolts, snaps, etc.). The compression structure also includes a compression surface that contacts the test piece, which is used to apply appropriate pressure to compress the test piece after it is mounted on the base 100.

[0058] The design of the clamping structure can be customized based on the shape, size, and testing requirements of the part being tested, ensuring a close fit between the clamping surface and the part being tested, achieving effective clamping. Furthermore, the clamping structure can be equipped with adjustment mechanisms, such as the tightening degree of the bolts and the locking force of the buckles, allowing the operator to adjust the clamping force according to actual needs, ensuring that the clamping effect is neither too tight, causing deformation of the part being tested, nor too loose, causing displacement during the test process.

[0059] By firmly pressing the inspected part with the clamping structure, it can be ensured that the inspected part will not be displaced or loosened during the inspection process, thereby avoiding the resulting errors and improving the accuracy of the inspection. The existence of the clamping structure enables the inspected part to maintain a stable state during the inspection process and will not change due to external forces or vibrations, thereby enhancing the reliability of the inspection. The design of the clamping structure can be customized according to the shape, size and inspection requirements of the inspected part, and is equipped with an adjustment mechanism, which allows the operator to more conveniently adjust the size of the clamping force to achieve effective clamping of the inspected part without increasing the complexity of the operation. Since the clamping structure can achieve firm clamping of the inspected part, the positioning and adjustment time during the inspection process can be shortened, thereby improving the inspection efficiency.

[0060] According to one embodiment of the present invention, the compression structure includes:

[0061] a mounting plate 114 disposed on top of the mounting post 112;

[0062] A handle 116 is rotatably connected to the mounting plate 114;

[0063] The pressing head 118 is rotatably connected to the mounting plate 114;

[0064] The connecting plate 120 is hinged between the handle 116 and the clamping head 118. The handle 116 is suitable for switching between a clamping position and a release position. In the clamping position, the clamping head 118 is suitable for clamping the inspected part. In the release position, the clamping head 118 is suitable for moving away from the inspected part.

[0065] In one embodiment of the present invention, the clamping structure mainly includes four key components: a mounting plate 114, a handle 116, a clamping head 118 and a connecting plate 120, which work together to achieve stable clamping and convenient operation of the inspected part.

[0066] Mounting plate 114, serving as the support base for the compression mechanism, is securely attached to the top of mounting post 112, providing a reliable mounting platform for handle 116, compression head 118, and connecting plate 120. Handle 116 is attached to mounting plate 114 via a swivel connection, allowing operators to easily rotate handle 116 to control the compression mechanism.

[0067] The clamping head 118 is the part that comes into direct contact with the inspected part. It is mounted on the mounting plate 114 via a rotatable connection and features a compression surface that matches the shape of the inspected part to ensure effective compression. This rotatable connection allows the clamping head 118 to rotate relative to the mounting plate 114 at a certain angle when driven by the handle 116, thereby tightening or loosening the inspected part.

[0068] The connecting plate 120 serves as the transmission mechanism between the handle 116 and the pressing head 118 and is connected to the handle 116 and the pressing head 118 via a hinged connection. When the operator turns the handle 116, the connecting plate 120 rotates accordingly and transmits the rotational torque to the pressing head 118 through the hinge point, causing the pressing head 118 to rotate accordingly, thereby tightening or loosening the inspected part.

[0069] The handle 116 is designed to switch between a tightening position and a loosening position. In the tightening position, the handle 116 drives the pressing head 118 to rotate via the connecting plate 120, so that the pressing surface of the pressing head 118 closely contacts the inspected part, achieving a secure clamping of the inspected part. In the loosening position, the handle 116 drives the pressing head 118 to rotate in the opposite direction via the connecting plate 120, moving the pressing head 118 away from the inspected part, facilitating installation and removal of the inspected part.

[0070] By rotating handle 116, the clamping head 118 securely clamps the inspected part, ensuring it does not shift or loosen during testing, thereby improving the accuracy and reliability of the test. The design of handle 116 allows the operator to control the clamping mechanism with a simple rotation, eliminating the need for additional tools or complex steps, significantly enhancing operational convenience. The various components of the clamping mechanism are connected through rotational and articulated connections, making the entire structure more stable and durable, ensuring stable performance over long-term use.

[0071] According to an embodiment of the present invention, a slideway 122 is provided on the base 100 , and the clearance detection member 102 is slidably connected to the slideway 122 .

[0072] In one embodiment of the present invention, a slideway 122 is added to the base 100, and the clearance detector 102 is mounted on the slideway 122 by a sliding connection. This design is intended to improve the mobility and positioning accuracy of the clearance detector 102, thereby further improving the efficiency and accuracy of clearance detection.

[0073] Specifically, the slideway 122 serves as a moving track for the clearance detector 102 and is securely mounted on the base 100. Its shape and size can be customized based on the movement and detection requirements of the clearance detector 102. The slideway 122 is typically designed using wear-resistant and corrosion-resistant materials to ensure good sliding performance and accuracy over long-term use.

[0074] The clearance detector 102 is mounted on the slideway 122 via a sliding connection. This connection allows the clearance detector 102 to slide smoothly and without vibration on the slideway 122. The design of the clearance detector 102 can be customized according to the shape, size, and testing requirements of the component being tested to ensure that it can accurately measure the clearance of the component being tested.

[0075] Auxiliary structures such as limit blocks or positioning pins can also be provided on the slideway 122 to limit the range of movement of the clearance detector 102 or to achieve precise positioning thereof. The design of these auxiliary structures can be customized according to the detection requirements to ensure that the clearance detector 102 can perform accurate measurements at the predetermined position.

[0076] The design of the slideway 122 allows the clearance detector 102 to slide smoothly and without vibration on the slideway 122, thereby improving its mobility and making it easier for the operator to adjust the position of the clearance detector 102. The design of the slideway 122 allows the clearance detector 102 to move along a predetermined path and, through auxiliary structures such as limit blocks or positioning pins, achieves precise positioning, thereby improving the accuracy of clearance detection. The design of the slideway 122 makes the movement and adjustment of the clearance detector 102 faster and more convenient, thereby shortening the positioning and adjustment time during the detection process and improving detection efficiency.

[0077] According to an embodiment of the present invention, a support leg 124 is provided on the slideway 122 , and the clearance detection member 102 is rotatably connected to the top of the support leg 124 .

[0078] In one embodiment of the present invention, the legs 124 serve as a supporting structure for the clearance detector 102 and are firmly connected to the slideway 122 . The number and position of the legs 124 can be customized according to the detection requirements and the shape of the detected part.

[0079] The clearance detector 102 is mounted on the top of the support leg 124 via a rotatable connection, which allows the clearance detector 102 to rotate a certain angle on the support leg 124. This rotatable connection design allows the clearance detector 102 to better adapt to the shape and size of the detected part, thereby ensuring close contact with the detected part during the detection process and achieving accurate measurement.

[0080] A rotating mechanism such as a rotating shaft or bearing may also be provided on the top of the support leg 124 to support the rotation of the clearance detector 102 and reduce friction and resistance during the rotation process. The design of these rotating mechanisms can be customized according to the detection requirements and the weight of the clearance detector 102 to ensure that the clearance detector 102 can rotate smoothly and steadily.

[0081] The design of the legs 124 and the rotatable connection allows the clearance detector 102 to rotate to a certain angle during the testing process, thereby increasing its flexibility and enabling the operator to more easily adjust the position and angle of the clearance detector 102 to accommodate the different shapes and sizes of the tested parts. The design of the legs 124 and the rotatable connection allows the clearance detector 102 to better adapt to the shape and size of the tested parts, ensuring close contact with the tested parts during the testing process, achieving accurate measurements, and improving the accuracy and reliability of the test.

[0082] According to an embodiment of the present invention, a rotating arm 126 is rotatably provided on the top of the supporting leg 124 , and the clearance detection member 102 is slidably connected to the rotating arm 126 .

[0083] In one embodiment of the present invention, the top of the leg 124 is designed to rotatably mount a rotating arm 126, and the clearance detection member 102 is mounted on the rotating arm 126 via a sliding connection. This design not only enhances the flexibility and adaptability of the clearance detection member 102, but also significantly improves the accuracy and efficiency of detection.

[0084] One end of the rotating arm 126 is connected to the top of the leg 124 via a bearing, a pin, or other rotating connection mechanism, ensuring that the rotating arm 126 can rotate around the top of the leg 124 to a certain angle. This rotating design allows the clearance detector 102 to be measured in a variety of postures, such as parallel to or tilted relative to the slide 122, thereby accommodating test pieces of different shapes and sizes.

[0085] The clearance detector 102 is mounted on the rotating arm 126 via a sliding connection. This connection allows the clearance detector 102 to slide along the rotating arm 126 in a specific direction. The sliding connection design enables the clearance detector 102 to be more precisely positioned at a specific location on the component being tested, thereby accurately measuring the clearance. Furthermore, the stability of the sliding connection ensures that the clearance detector 102 will not shift due to vibration or external forces during the measurement process.

[0086] The rotatable design of the rotating arm 126 allows the clearance detector 102 to be freely adjusted in multiple directions to accommodate test parts of varying shapes and sizes. This flexibility not only improves detection efficiency but also reduces operational difficulty. The combination of the rotating arm 126 and the sliding connection allows the clearance detector 102 to fit more closely to the test part, ensuring stable contact with the test part during measurement. This design significantly improves detection accuracy and reliability.

[0087] According to an embodiment of the present invention, a second sliding groove 128 is defined at the first end of the rotating arm 126 away from the supporting leg 124 , and the clearance detecting member 102 is slidably connected to the second sliding groove 128 .

[0088] In one embodiment of the present invention, the design of the rotating arm 126 has been further optimized, with a second slot 128 defined at its first end, facing away from the support leg 124. The clearance detector 102 is precisely mounted within this slot via a sliding connection. This design not only improves the positioning accuracy and flexibility of the clearance detector 102, but also enhances the adaptability and efficiency of the entire detection system.

[0089] Specifically, the pivoting arm 126, a key component connecting the leg 124 to the clearance detector 102, is designed to fully address various requirements during the inspection process. One end of the pivoting arm 126 is connected to the leg 124 via a rotating connection, ensuring that it can rotate around the leg 124 to a certain angle to accommodate inspected parts of varying shapes and sizes. A second slot 128 is provided at the other end of the pivoting arm 126, facing away from the leg 124.

[0090] The clearance detector 102 is mounted within the second chute 128 via a sliding connection. This connection allows the clearance detector 102 to slide in a specific direction within the chute, enabling precise measurement of different parts of the component being tested. The stability of the sliding connection also ensures that the clearance detector 102 will not shift due to vibration or external forces during measurement, thereby improving measurement accuracy and reliability.

[0091] The design of the second chute 128 enables the clearance detector 102 to be precisely positioned at a specific location on the inspected part, thereby improving measurement accuracy. The rotating design of the rotating arm 126 and the sliding connection of the second chute 128 enable the clearance detector 102 to be freely adjusted in multiple directions to accommodate inspected parts of varying shapes and sizes, enhancing detection flexibility. The design of the rotating arm 126 and the second chute 128 allows the operator to more easily adjust the position and posture of the clearance detector 102 without the use of complex tools or tedious procedures, thereby improving work efficiency.

[0092] According to one embodiment of the present invention, a first limiting member 130 is provided on the rotating arm 126, and the rotating arm 126 is adapted to limit the relative rotation angle with the supporting leg 124 through the limiting member;

[0093] and / or,

[0094] A second limiting member 132 is provided on the slideway 122 .

[0095] In one embodiment of the present invention, a first limit member 130 is provided on the rotating arm 126 for limiting the relative rotation angle between the rotating arm 126 and the support leg 124; at the same time, a second limit member 132 can also be provided on the slide 122 for limiting the movement range of the clearance detection member 102 or the rotating arm 126 on the slide 122.

[0096] A first stopper 130 is positioned on the pivot arm 126. Its position and shape are precisely calculated to ensure a stable connection between the pivot arm 126 and the leg 124 during rotation and to limit their relative rotation angle. This design prevents excessive rotation of the pivot arm 126, which could damage the connection mechanism or cause unstable contact between the clearance detector 102 and the inspected component. The first stopper 130 can be mechanical, electromagnetic, or hydraulic, depending on the requirements of the detection system and the operating environment.

[0097] The second limiter 132 on the slideway 122 is used to limit the range of movement of the clearance detector 102 or the rotating arm 126 on the slideway 122. This design prevents the clearance detector 102 from sliding beyond a predetermined range, potentially damaging the slideway 122 or colliding with the detected component. The second limiter 132 can also take a variety of forms, such as a mechanical limit block, an electromagnetic limit switch, or a photoelectric limit sensor. The specific choice depends on the accuracy requirements of the detection system and the operating environment.

[0098] The design of the first stopper 130 and the second stopper 132 together ensures the stability of the clearance detector 102 during the testing process, preventing damage or errors caused by excessive rotation or sliding. The design of the first stopper 130 limits the range of motion of the rotating arm 126 and the clearance detector 102, thereby ensuring that the clearance detector 102 can be accurately positioned at a specific location on the tested component during measurement, thereby improving measurement accuracy.
