Description

Technical Field

[0001] The present application relates to the technical field of part wall thickness detection, and in particular to a curved surface thickness detection device. Background Art

[0002] At present, in machining, the wall thickness detection method for some parts is usually to use a three-coordinate measuring machine to perform point-to-point detection on the detection station, or to use a handheld point-to-point meter inspection fixture for detection.

[0003] When a component has a curved structure and the inspection station is a small station on the curved surface, if a three-coordinate measuring machine is used, the instrument has high requirements for the inspection environment and it is difficult to perform local inspection at the production site; and a handheld point-to-point meter gauge requires workers to manually adjust the gauge and the inspection station on the product to be perpendicular, which is inconvenient and difficult to ensure that the inspection accuracy meets the inspection requirements. Summary of the invention

[0004] In view of this, the present application provides a curved surface thickness detection device to solve the technical problems of inconvenience in detecting the wall thickness of a small workstation on a curved surface structure and difficulty in ensuring the detection accuracy.

[0005] One embodiment of the present application provides a curved surface thickness detection device. The curved surface thickness detection device includes a workbench, a measuring table, a detection member and an elastic member. The workbench has a bearing surface. The bearing surface is used to bear the workpiece to be detected. The measuring table is arranged on the workbench. The measuring table includes a table body, a table head and a contact. The contact is fixedly connected to the table body. The table head is movably connected to the table body and can move relative to the table body along a detection direction. The detection direction intersects with the bearing surface. The detection member is arranged on the workbench. The detection member includes a support portion and a detection portion. The support portion is used to support a portion to be detected of the workpiece to be detected. The table body is configured to be movable relative to the detection member along the detection direction so that the distance between the contact and the support portion is adjustable. The elastic member is used to apply an elastic force to the detection member along the detection direction so that the support portion and the detection portion move synchronously. When the contact and the support portion are respectively abutted against the two sides of the portion to be detected, the detection portion and the table head are abutted.

[0006] The use process includes two steps: zeroing and testing. First, make the contact and the support part abut against each other and the meter head and the detection part abut against each other, and then reset the measuring meter to zero. When testing is required, move the meter body so that the contact is away from the support part, place the part to be tested of the workpiece to be tested on the support part, and then move the meter body so that the contact is close to the support part until the contact and the support part abut against the two sides of the part to be tested respectively; the meter head will move in the direction close to the detection part until it abuts against the detection part, and the distance the meter head moves relative to the meter body is the thickness value of the part to be tested. The detection process is stable and reliable, and the detection accuracy can meet the detection requirements. Providing an elastic member that applies elastic force to the detection member along the detection direction helps to ensure that the detection member always maintains an appropriate contact pressure. When the part to be tested of the workpiece to be tested is not a completely flat surface, the elastic member can achieve adaptive adjustment, thereby achieving effective and accurate detection.

[0007] In some embodiments of the present application, the curved surface thickness detection device further comprises a support positioning mechanism. The support positioning mechanism is detachably connected to the workbench. The detection member is arranged on the support positioning mechanism. The meter body is movably connected to the support positioning mechanism and can move relative to the support positioning mechanism. The support positioning mechanism is configured so that the angle between the detection direction and the bearing surface is adjustable.

[0008] In this way, the inclination of the detection direction relative to the bearing surface can be changed through the support and positioning mechanism. When implemented, different support and positioning mechanisms can be replaced according to the angle between the workpiece to be detected with a curved surface and the bearing surface; or the support and positioning mechanism itself has a structure that can be rotated and adjusted, so that the angle between the detection direction and the bearing surface is adjustable. The support and positioning mechanism is conducive to making the detected part of the workpiece to be detected perpendicular to the detection direction, which helps to improve the detection accuracy of curved products and can improve the applicability of curved surface thickness detection devices.

[0009] In some embodiments of the present application, the meter body is movably connected to the support and positioning mechanism. The meter body moves relative to the support and positioning mechanism along the detection direction, and the meter body can drive the contact to rotate relative to the support and positioning mechanism around the rotation axis. The distance between the contact and the rotation axis is greater than zero.

[0010] Since the meter body is inclined relative to the bearing surface, the meter body is further arranged to be rotatable relative to the supporting positioning mechanism. In this way, when clamping the workpiece to be tested, the meter body is rotated so that the contact is away from the supporting part to make way for the workpiece to be tested, making it convenient for the staff to clamp the workpiece to be tested on the workbench.

[0011] In some embodiments of the present application, the supporting and positioning mechanism includes a connecting member. The connecting member is detachably connected to the workbench. The meter body includes a mounting portion. The meter body is movably connected to the connecting member through the mounting portion. The connecting member includes a first connecting portion and a second connecting portion. The mounting portion is movably connected to the first connecting portion. The second connecting portion is used to accommodate the detection member. The detection member is arranged in the second connecting portion and can move relative to the connecting member under the action of the elastic member.

[0012] The connector can improve the connection strength between the measuring table and the detection part and the workbench. Install the connector on the workbench, and then install the measuring table, the detection part and the elastic part on the connector, which ensures that the measuring table can achieve effective measurement while improving the structural strength and stability of the entire detection device.

[0013] In some embodiments of the present application, the support and positioning mechanism further comprises a support member. The support member is detachably connected to the workbench. The support member has a support surface. The detection direction is perpendicular to the support surface. The connecting member is disposed on the support surface and is detachably connected to the support member. The elastic member is disposed between the detection member and the support surface. One end of the elastic member abuts against the detection member, and the other end of the elastic member abuts against the support surface, and the elastic member is compressed.

[0014] Since the supporting surface of the supporting member is perpendicular to the detection direction, when the angle between the detection direction and the supporting surface needs to be adjusted, the corresponding supporting member can be replaced.

[0015] In some embodiments of the present application, the second connecting portion is provided with a first connecting hole and a second connecting hole. The axial direction of the first connecting hole is parallel to the detection direction. The axial direction of the second connecting hole is parallel to the detection direction. The first connecting hole is used to accommodate the support portion. The second connecting hole is used to accommodate the detection portion. Under the action of the elastic member, the support portion passes through the first connecting hole and abuts against the contact. Under the action of the elastic member, the detection portion passes through the second connecting hole and abuts against the meter head.

[0016] The second connection part is provided with a first connection hole and a second connection hole for the support part and the detection part to pass through. When the detection part is adaptively adjusted under the action of the elastic part, the movement of the detection part is guided by the first connection hole and the second connection hole, which helps to ensure that the detection direction is as perpendicular to the part to be detected as possible.

[0017] In some embodiments of the present application, the support and positioning mechanism is provided with a third connection hole. The axial direction of the third connection hole is parallel to the detection direction. The meter body is movably arranged in the third connection hole so that the measuring meter can rotate or move relative to the support and positioning mechanism.

[0018] The third connection hole for connecting the meter body is provided in the support positioning mechanism, which helps to guide the movement of the meter body in the detection direction. The meter body is movably arranged in the third connection hole, so that the translation and rotation of the meter body share one hole, which helps to make the overall structure more compact.

[0019] In some embodiments of the present application, the detection member further comprises a base. The base extends along the detection direction. The base is movably connected to the support member. The elastic member is a spring. The spring is wound around the base and compressed between the support surface and the detection member.

[0020] The detection member is connected to the support member through the base, which helps to improve the connection stability between the detection member and the support positioning mechanism. When the elastic member is a spring, the base can also provide a location for the spring to be wound, making the compression and recovery deformation of the spring more stable.

[0021] In some embodiments of the present application, the support and positioning mechanism further includes a limiter. The limiter is connected to the support and positioning mechanism. The limiter is used to stop the measuring meter from rotating relative to the support and positioning mechanism. When the measuring meter rotates relative to the support and positioning mechanism until the contact and the support part abut and the meter head and the detection part abut, the limiter abuts against the meter body to achieve the stop.

[0022] When clamping the workpiece to be tested, the measuring table is rotated to make way, and then the measuring table is rotated in the opposite direction. At the same time, the limiter and the table body are in contact, the contact and the support part are in contact, and the table head and the detection part are in contact. In this way, it can effectively ensure that the position between the measuring table and the detection part is in an effective detection position.

[0023] In some embodiments of the present application, the curved surface thickness detection device further comprises a positioning member. The positioning member is arranged on the bearing surface. The positioning member is used to limit the movement of the workpiece to be detected relative to the bearing surface.

[0024] In this way, by providing the positioning piece, the workpiece to be inspected can be restricted from entering between the meter header and the inspection part. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0030] Herein, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0031] The term "perpendicular" is used to describe the ideal state between two components. In actual production or use, the two components may be approximately perpendicular to each other. The two components described as "perpendicular" may not be absolutely straight lines or planes, but may be roughly straight lines or planes. From a macroscopic point of view, the components can be considered "straight lines" or "planes" if the overall extension direction is a straight line or a plane.

[0032] The term "parallel" is used to describe an ideal state between two parts. The two parts described as "parallel" may not be absolutely straight lines or planes, but may be roughly straight lines or planes. From a macroscopic point of view, the parts can be considered "straight lines" or "planes" if the overall extension direction is a straight line or a plane.

[0033] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. When an element is considered to be "set on" another element, it may be directly set on the other element or there may be a central element at the same time.

[0034] An embodiment of the present application provides a curved surface thickness detection device. The curved surface thickness detection device includes a workbench, a measuring table, a detection member and an elastic member. The workbench has a bearing surface. The bearing surface is used to bear a workpiece to be detected. The measuring table is arranged on the workbench. The measuring table includes a table body, a table head and a contact. The contact is fixedly connected to the table body. The table head is movably connected to the table body and can move relative to the table body along a detection direction. The detection direction intersects with the bearing surface. The detection member is arranged on the workbench. The detection member includes a support portion and a detection portion. The support portion is used to support a portion to be detected of the workpiece to be detected. The table body is configured to be able to move relative to the detection member along the detection direction so that the distance between the contact and the support portion is adjustable. The elastic member is used to apply an elastic force to the detection member along the detection direction so that the support portion and the detection portion move synchronously. When the contact and the support portion are respectively abutted against two sides of the portion to be detected, the detection portion and the table head are abutted.

[0035] For some workpieces with curved structures, and the parts to be tested are some small workstations on the curved surface. During testing, it is necessary to make the axis of the detection contact of the gauge as perpendicular to the part to be tested as possible, so that the measurement value of the gauge will be as close to the thickness value of the part to be tested as possible. Conventional handheld gauges require staff to adjust repeatedly to ensure that the axis of the detection contact is as perpendicular to the part to be tested as possible. There are inconveniences in adjusting both the gauge and the workpiece to be tested, and this adjustment is completed visually by the staff, and the detection accuracy is still difficult to guarantee.

[0036] The use process includes two steps: zeroing and testing. First, make the contact and the support part abut against each other and the meter head and the detection part abut against each other, and then reset the measuring meter to zero. When testing is required, move the meter body so that the contact is away from the support part, place the part to be tested of the workpiece to be tested on the support part, and then move the meter body so that the contact is close to the support part until the contact and the support part abut against the two sides of the part to be tested respectively; the meter head will move in the direction close to the detection part until it abuts against the detection part, and the distance the meter head moves relative to the meter body is the thickness value of the part to be tested. The detection process is stable and reliable, and the detection accuracy can meet the detection requirements. Providing an elastic member that applies elastic force to the detection member along the detection direction helps to ensure that the detection member always maintains an appropriate contact pressure. When the part to be tested of the workpiece to be tested is not a completely flat surface, the elastic member can achieve adaptive adjustment, thereby achieving effective and accurate detection.

[0037] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] See also Figures 1 to 3, an embodiment of the present application provides a curved surface thickness detection device 100. The curved surface thickness detection device 100 includes a workbench 1, a measuring table 2, a detection member 3 and an elastic member 4. The workbench 1 has a bearing surface 101. The bearing surface 101 is used to bear a workpiece 7 to be detected. The measuring table 2 is disposed on the workbench 1. The measuring table 2 includes a table body 21, a table head 22 and a contact 23. The contact 23 is fixedly connected to the table body 21. The table head 22 is movably connected to the table body 21 and can move relative to the table body 21 along a detection direction P. The detection direction P intersects with the bearing surface 101. The detection member 3 is disposed on the workbench 1. The detection member 3 includes a support portion 31 and a detection portion 32. The support portion 31 is used to support a portion 701 to be detected of the workpiece 7 to be detected. The table body 21 is configured to be movable relative to the detection member 3 along the detection direction P so that the distance between the contact 23 and the support portion 31 is adjustable. The elastic member 4 is used to apply elastic force to the detection member 3 along the detection direction P to make the support portion 31 and the detection portion 32 move synchronously. When the contact 23 and the support portion 31 are respectively in contact with the two sides of the part to be detected 701, the detection portion 32 and the meter head 22 are in contact. In some embodiments, the detection meter is a dial gauge or a micrometer.

[0039] The use process includes two steps: zeroing and testing. First, make the contact 23 and the support part 31 abut against each other and the header 22 and the detection part 32 abut against each other, and then reset the measuring meter 2 to zero. When testing is required, move the meter body 21 so that the contact 23 is away from the support part 31, place the test part 701 of the workpiece 7 to be tested on the support part 31, and then move the meter body 21 so that the contact 23 is close to the support part 31, until the contact 23 and the support part 31 are respectively abutted against the two sides of the test part 701; the header 22 will move in the direction close to the detection part 32 until it abuts against the detection part 32, and the distance that the header 22 moves relative to the meter body 21 is the thickness value of the test part 701. The detection process is stable and reliable, and the detection accuracy can also meet the detection requirements. The elastic member 4 that applies elastic force to the detection member 3 along the detection direction P helps to ensure that the detection member 3 always maintains an appropriate contact pressure. When the detection portion 701 of the workpiece 7 to be detected is not a completely flat surface, the elastic member 4 can achieve adaptive adjustment, thereby achieving effective and accurate detection. During the entire use process, the staff does not need to manually adjust the workpiece 7 to be detected or the measuring table 2, and the operation is convenient and simple.

[0040] In some embodiments, the curved surface thickness detection device 100 further includes a support positioning mechanism 5. The support positioning mechanism 5 is detachably connected to the workbench 1. The detection member 3 is disposed on the support positioning mechanism 5. The watch body 21 is movably connected to the support positioning mechanism 5 and can move relative to the support positioning mechanism 5. The support positioning mechanism 5 is configured so that the angle between the detection direction P and the bearing surface 101 is adjustable.

[0041] In this way, the inclination of the detection direction P relative to the bearing surface 101 can be changed by the support and positioning mechanism 5. In implementation, different support and positioning mechanisms 5 can be replaced according to the angle between the workpiece 7 to be detected with a curved surface and the bearing surface 101; or the support and positioning mechanism 5 itself has a structure that can be rotated and adjusted, so that the angle between the detection direction P and the bearing surface 101 is adjustable. The support and positioning mechanism 5 is conducive to making the detection part 701 of the workpiece 7 to be detected perpendicular to the detection direction P, which helps to improve the detection accuracy of curved products and can improve the applicability of the curved surface thickness detection device 100.

[0042] See also Figure 2 and Figure 4 In some embodiments, the meter body 21 is movably connected to the support and positioning mechanism 5. The meter body 21 moves relative to the support and positioning mechanism 5 along the detection direction P, and the meter body 21 can drive the contact 23 to rotate relative to the support and positioning mechanism 5 around the rotation axis R. The distance between the contact 23 and the rotation axis R is greater than zero.

[0043] Since the meter body 21 is inclined relative to the bearing surface 101, the meter body 21 is further arranged to be rotatable relative to the supporting positioning mechanism 5. In this way, when clamping the workpiece 7 to be detected, the meter body 21 is rotated so that the contact 23 is away from the supporting portion 31 to make way for the workpiece 7 to be detected, making it convenient for the staff to clamp the workpiece 7 to be detected to the workbench 1. Figure 2 and Figure 4 As shown, the rotation axis R and the detection direction P are parallel.

[0044] In some embodiments, the supporting and positioning mechanism 5 includes a connecting member 51. The connecting member 51 is detachably connected to the workbench 1. The meter body 21 includes a mounting portion 24. The meter body 21 is movably connected to the connecting member 51 through the mounting portion 24. The connecting member 51 includes a first connecting portion 511 and a second connecting portion 512. The mounting portion 24 is movably connected to the first connecting portion 511. The second connecting portion 512 is used to accommodate the detection member 3. The detection member 3 is arranged in the second connecting portion 512 and can move relative to the connecting member 51 under the action of the elastic member 4.

[0045] The connecting member 51 can improve the connection strength between the measuring table 2 and the detection member 3 and the workbench 1. The connecting member 51 is installed on the workbench 1, and then the measuring table 2, the detection member 3 and the elastic member 4 are installed on the connecting member 51, which ensures that the measuring table 2 can achieve effective measurement while improving the structural strength and stability of the entire detection device.

[0046] In some embodiments, the support and positioning mechanism 5 further includes a support member 52. The support member 52 is detachably connected to the workbench 1. The support member 52 has a support surface 521. The detection direction P is perpendicular to the support surface 521. The connecting member 51 is disposed on the support surface 521 and is detachably connected to the support member 52. The elastic member 4 is disposed between the detection member 3 and the support surface 521. One end of the elastic member 4 abuts against the detection member 3, and the other end of the elastic member 4 abuts against the support surface 521, and the elastic member 4 is compressed.

[0047] Since the detection direction P is perpendicular to the support surface 521 of the support member 52, when the workpiece 7 to be detected with a different curved surface structure is replaced, that is, when the angle between the detection direction P and the bearing surface 101 needs to be adjusted, the corresponding support member 52 can be replaced. Of course, the support member 52 can also be designed as a structure in which the angle between the support surface 521 and the bearing surface 101 is adjustable. For example, a telescopic structure is provided inside the support member 52, and the telescopic structure changes the angle between the support surface 521 and the bearing surface 101 by extending or contracting, so that the support surface 521 is perpendicular to the detection direction P. It can be understood that in the present application and various embodiments, the detection direction P is not fixed, and the detection direction P is always consistent with the moving direction of the meter head 22. Therefore, the detection direction P can be made perpendicular to the part to be detected 701 by the support positioning mechanism 5, so that the detection accuracy meets the detection requirements.

[0048] In some embodiments, the second connecting portion 512 is provided with a first connecting hole 5121 and a second connecting hole 5122. The axial direction of the first connecting hole 5121 is parallel to the detection direction P. The axial direction of the second connecting hole 5122 is parallel to the detection direction P. The first connecting hole 5121 is used to accommodate the support portion 31. The second connecting hole 5122 is used to accommodate the detection portion 32. Under the action of the elastic member 4, the support portion 31 passes through the first connecting hole 5121 and abuts against the contact 23. Under the action of the elastic member 4, the detection portion 32 passes through the second connecting hole 5122 and abuts against the meter head 22.

[0049] The second connection portion 512 is provided with a first connection hole 5121 and a second connection hole 5122 for the support portion 31 and the detection portion 32 to pass through. When the detection member 3 is adaptively adjusted under the action of the elastic member 4, the movement of the detection member 3 is guided by the first connection hole 5121 and the second connection hole 5122, which helps to ensure that the detection direction P is as perpendicular to the part to be detected 701 as possible.

[0050] In some embodiments, the support and positioning mechanism 5 is provided with a third connection hole 53 . The axial direction of the third connection hole 53 is parallel to the detection direction P. The meter body 21 is movably arranged in the third connection hole 53 so that the measuring meter 2 can rotate or move relative to the support and positioning mechanism 5 .

[0051] The third connection hole 53 for connecting the watch body 21 is provided in the support and positioning mechanism 5, which helps to guide the movement of the watch body 21 in the detection direction P. The watch body 21 is movably arranged in the third connection hole 53, so that the translation and rotation of the watch body 21 share one hole, which helps to make the overall structure more compact. Figure 2 and Figure 3 In the illustrated embodiment, the first connection portion 511 is the third connection hole 53 .

[0052] In some embodiments, the detection member 3 further includes a base 33. The base 33 extends along the detection direction P. The base 33 is movably connected to the support member 52. The elastic member 4 is a spring. The spring is wound around the base 33 and compressed between the support surface 521 and the detection member 3.

[0053] The detection member 3 is connected to the support member 52 via the base 33, which helps to improve the connection stability between the detection member 3 and the support and positioning mechanism 5. When the elastic member 4 is a spring, the base 33 can also provide a location for the spring to be wound, making the compression and recovery deformation of the spring more stable.

[0054] In some embodiments, the support and positioning mechanism 5 further includes a stopper 54. The stopper 54 is connected to the connecting member 51. The stopper 54 is used to stop the measuring meter 2 from rotating relative to the connecting member 51. When the measuring meter 2 rotates relative to the connecting member 51 until the contact 23 abuts against the supporting portion 31 and the meter head 22 abuts against the detecting portion 32, the stopper 54 abuts against the meter body 21 to achieve stopping.

[0055] When clamping the workpiece 7 to be inspected, the measuring table 2 is rotated to make way, and then the measuring table 2 is rotated in the opposite direction, and the stopper 54 abuts against the table body 21, while the contact 23 abuts against the support part 31 and the table head 22 abuts against the detection part 32. In this way, it can be effectively ensured that the position between the measuring table 2 and the detection member 3 is in an effective detection position.

[0056] In some embodiments, the curved surface thickness detection device 100 further includes a positioning member 6. The positioning member 6 is disposed on the bearing surface 101. The positioning member 6 is used to limit the movement of the workpiece 7 to be detected relative to the bearing surface 101.

[0057] In this way, after the workpiece 7 to be tested is clamped onto the workbench 1 , the positioning member 6 can make the tested portion 701 located between the contact 23 and the support portion 31 and not enter between the meter head 22 and the detection portion 32 .

[0058] In some embodiments, the support portion 31 can be a support column independent of the detection member 3, and the support column and the detection member 3 are fixedly connected or tightly fitted through a connecting hole, and the base 33 can also be a connecting pin independent of the detection member 3, and the connecting pin and the detection member are fixedly connected or also tightly fitted through a connecting hole. The advantage of this is that it is convenient to process the detection member 3. In addition, ordinary technicians in this technical field should realize that the above implementation methods are only used to illustrate the present application, and are not used as a limitation of the present application. As long as they are within the substantive spirit of the present application, appropriate changes and modifications made to the above embodiments are within the scope of the disclosure of the present application.
