Description

TECHNICAL FIELD

[0001] The present disclosure relates to testing of fasteners. BACKGROUND

[0002] The Junker test is a mechanical test used to determine the point at which a joint secured by a threaded fastener loses its preload due to self-loosening of the threaded fastener when subjected to shear loads caused by lateral vibrations. Standards for the Junker vibration test can be found in SAE document 690055 entitled "New Criteria for Self-Loosening of Fasteners Under Vibration." Known machines for performing the Junker test are not practical for verification purposes because the machines are bulky and therefore not easily transportable. Additionally, it is problematic to test multiple fasteners in a short period of time, for example for verification purposes, using known Junker test machines because the known machines accommodate only one fastener at a time and this one fastener needs to be properly installed in the machine with the appropriate preload before being tested. This makes it difficult to compare different fasteners and / or different thread lockers applied to the fasteners to verify their different performance. SUMMARY

[0003] The present disclosure provides improved systems for performing vibration testing of joints secured by threaded fasteners and testing and comparing adhesive thread lockers applied to such threaded fasteners.

[0039] ​​​​​​​​​​​​Before the embodiments are described in detail the following aspects should be understood to be applicable to the embodiments: the application is not limited to the specific embodiments described; the terminology used is for the purpose of describing particular embodiments only and is not intended to limit the scope of the claims of this application.

[0040] In the drawings, where specific embodiments can only be described with respect to a particular drawing and reference number, it should be understood that such description can equally apply to like reference numbers in other drawings. Additionally, while various features can be shown in different drawings for purposes of simplification, it is contemplated that various features can be combined without departing from the scope of the disclosure.

[0041] Figure 1 A fastener testing system 10 according to the present disclosure is shown. The fastener testing system 10 includes a vibration testing apparatus 12 and one or more test pieces 14. The vibration testing apparatus 12 includes a test station 16 and a preparation station 18 disposed in a body 20. The vibration testing apparatus 12 can also include an ejection system 21 to assist in the removal of the test pieces 14 from the test station 16 and / or the preparation station 18 and a stabilization handle 22 at an end of the body 20.

[0042] The test station 16 includes a fixed base member 24 and an upper member 26 defining a test cavity 27 configured to receive the test pieces 14 therein. The upper member 26 is disposed on the base member 24 and is configured to slide in a reciprocating lateral motion relative to the base member 24.

[0043] The preparation station 18 is separate from the test station 16 and includes a cavity 28 configured to receive the test pieces 14 therein for preparation of the test pieces 14 for subsequent testing in the test station 16. The inner walls defining the cavity 28 of the preparation station 18 can have a stepped configuration such that a lower portion 30 of the cavity 28 is smaller than an upper portion 31 of the cavity 28.

[0044] Referring to Figure 2 and 3 , the vibration testing apparatus 12 also includes an electrically powered drive assembly 32 located within the body 20. The electrically powered drive assembly 32 includes a motor 34 or other similar drive mechanism as shown in Figure 2 and a gear transmission 36 connecting the motor 34 to the upper member 36 of the test station 16. The gear transmission 36 is configured to convert the rotational motion of the motor 34 as shown in Figure 2 to a reciprocating motion to drive the upper member 26 in a reciprocating lateral motion relative to the base member 24 along an axis 38. As shown in Figure 3As shown, the vibration testing apparatus 12 includes a controller 40 for controlling the electrically actuated drive assembly 32, and a motor control input 42 operatively connected to the controller 40.

[0045] Referring to Figure 4 , the vibration testing apparatus 12 can also include a display 44 and a sensor port 46 operatively coupled to the controller 40, as shown. Figure 3 The vibration testing apparatus 12 can also include a manual input 48 that allows a user to manually rotate the motor 34, as shown. Figure 2 For example, the manual input 48 can be a knob or the like coupled to a shaft of the motor 34 that, when rotated, can effect a corresponding rotation of the shaft. Such rotation results in a manual actuation of the electrically actuated drive assembly 32 and the upper member 26 of the test piece 16, as shown. Figure 2 This facilitates the alignment of the upper member 26 relative to the base member 24, such that the test piece 14 can be inserted into the test station 16, as shown. Figure 1

[0046] Although the motor control input 42 is shown as a button for simplicity in Figure 3 and 4 , the motor control input 42 can be any other type of known input device such as a switch, dial, lever, touch screen, etc. and / or combinations thereof.

[0047] Referring to Figure 5 , an ejection system 21 is shown for assisting in the removal of the test piece 14 from the test station 16 and / or the preparation station 18, as shown. Figure 1 The ejection system 21 includes a handle 50 fixed to a shaft member 52 that is rotatably coupled to an underside of the body 20 by a bearing 54. The shaft member 52 includes a first cam member 56 fixed to the shaft member adjacent the test station 16 and cooperating with an opening 58 formed through a bottom surface of the test station 16. The shaft member 52 also includes a second cam member 60 fixed to the shaft member adjacent the preparation station 18 and cooperating with an opening 62 formed through a bottom surface of the preparation station 18. The ejection system 12 can also include a biasing member 64, such as a spring or the like, that biases the ejection system 21 toward an inoperable position, as shown. Figure 5 The handle 50 is movable in a direction 66 from the inoperable position, as shown, to an ejection position. As the handle 50 is moved, the first cam member 56 moves upwardly through the opening 58 into the test station 16, and the second cam member 60 moves upwardly through the opening 62 into the preparation station 18. Figure 5

[0048] Referring to Figures 6 to 8 ​​Each test piece 14 of the fastener testing system 10 includes a lower connector member 68, an upper connector member 70, and a fastener 72 that secures the lower connector member 68 and the upper connector member 70 together. The test piece 14 may have a stepped design, with the lower connector member 68 being smaller than the upper connector member 70.

[0049] like Figure 7 As shown, in addition to fastener 72, alignment bolt 73 can also secure the upper connector member 70 to the lower connector member 68. Alignment bolt 73 threadedly engages one of the upper connector member 70 or the lower connector member 68, and has a clearance fit with the other, thereby allowing lateral movement of the upper connector member 70 relative to the lower connector member 68. For example, as... Figure 7 As shown, the upper connector component 70 has a clearance fit with the alignment bolt 73, while the lower connector component 68 is threadedly engaged with the alignment bolt 73. (As shown...) Figure 8 As shown, test piece 14 may also include a bearing 74, such as a needle roller bearing, which is positioned between the lower connector member 68 and the upper connector member 70. The bearing 74 reduces friction between the lower connector member 68 and the upper connector member 70, thus making it easier for the upper connector member 70 to move laterally relative to the lower connector member 68 during testing, thereby requiring less power.

[0050] Looking back Figure 6 The upper connector member 70 has a sensor 75, such as a strain gauge, fixed thereto. The upper connector member 70 may also include a transverse groove 76 adjacent to the fastener 72, across which the sensor 75 is positioned to amplify the readings acquired by the sensor 75, as the transverse groove 76 provides stress concentration. Before testing the test piece 14, the sensor transmitter 78 can be attached to the test piece 14 by one or more screws 80. The sensor transmitter 78 is connected to the sensor 75 via a wire 82, etc., and can be connected via, for example,... Figure 4 The cable 84 shown is connected to, as Figure 4 The sensor port 46 of the vibration testing device 12 shown facilitates communication between the sensor 75 and the controller 40 of the vibration testing device 12, such as... Figure 3 As shown.

[0051] The lower connector member 68 may include a positioning hole 86, the positioning hole being configured as follows: Figure 1 The positioning screw component 88 of the vibration testing device 12 shown engages, thereby aligning and / or positioning the test piece 14 as shown during the test. Figure 1In the test station 16 shown. Additionally, to ensure that the test piece 14 is aligned and / or positioned within the test station 16 regardless of orientation, the lower connector member 68 may include a positioning hole 86 on its opposite side, such as... Figure 7 As shown.

[0052] See Figure 9 During operation, each test piece 14 is prepared for testing within the preparation station 18. For example, each test piece 14 may be assembled within the preparation station 18, or alternatively, each test piece 14 may be pre-assembled before insertion into the preparation station 18, in such a way that fasteners 72 are applied as follows: Figure 8 The lower connector 68 and upper connector 70 are held together, but the fasteners are not yet torqued to their final desired torque specifications, thus allowing a certain degree of relative movement between the lower connector 68 and upper connector 70. If the performance and / or characteristics of the threadlocker will be tested in the vibration testing equipment 12, the threadlocker can be applied to the fastener 72 during assembly or pre-assembly.

[0053] See Figure 10 When the lower connector 68 and the upper connector 70 are inserted into the cavity 28 of the preparation station 18 (during assembly or as a pre-assembled test piece 14), the stepped construction of the inner wall 27 ensures that the upper connector 70 is correctly positioned relative to the lower connector 68. The fastener 72 can then be torqued to its final desired torque specification to couple the lower connector 68 and the upper connector 70 together.

[0054] See Figure 11 When the test piece 14 is in the preparation position 18, the sensor 75 can be fixed to the test piece 14, for example, by screws. As described above, the sensor 75 can be positioned across the transverse groove 76 formed in the upper connector member 70, thereby amplifying the readings acquired by the sensor 75 during the testing of the test piece 14.

[0055] See Figure 12 When test piece 14 is in preparation station 18, sensor transmitter 78 can be activated via, for example... Figure 6 The wires 82 shown are connected to the sensor 75 and can also be attached to the test piece 14 by screws 80. After being mounted on the test piece 14, the sensor transmitter 78 advantageously forms a protective cover for the sensor 75.

[0056] See Figure 13 After test piece 14 has been prepared in preparation station 18, test piece 14 can be removed from it using ejection system 21. Specifically, handle 50 can be used as follows: Figure 5 As shown in direction 66, from... Figure 11The inoperable position shown is pushed to the ejected position. As handle 50 moves, shaft 52 rotates and second cam member 60 moves upward through opening 62 into preparation station 18, pushing against test piece 14. This causes test piece 14 to move upward out of cavity 28. Handle 50 can then be returned to the inoperable position. For example, in the case where ejection system 21 includes bias member 64, handle 50 can be simply released to allow bias member 64 to return ejection system 21 to the inoperable position.

[0057] Additional test pieces 14 can be prepared in the same manner as described above. For example, if different threadlockers are to be tested and compared, multiple test pieces 14 can be prepared in the same manner as described above, with each test piece 14 having one of the different threadlockers applied to the fastener 72 of the test piece 14.

[0058] Although when test piece 14 is positioned in preparation station 18, as Figure 6 The sensor 75 and sensor transmitter 78 shown are mounted on the test piece 14 as described above, but in fact, the sensor 75 and sensor transmitter 78 can be mounted on the test piece 14 after the test piece 14 has been removed from the preparation station 18 in the manner described above.

[0059] See Figure 14 After the test piece 14 has been prepared, each test piece 14 is then inserted into the test station 16 of the vibration testing equipment 12 for testing as shown in the figure. During the insertion of the test piece 14 into the test station 16, as... Figure 4 The manual input unit 48 shown can be used to slide the upper component 26 of the test station 16 relative to the base component 24, thereby correctly aligning the upper component 26 relative to the base component 24 to accommodate the stepped shape of the test piece 14 so that the test piece 14 can be inserted into the test station 16. After the test piece 14 has been inserted into the test station 16, the sensor transmitter 78 can be connected to the sensor port 46 via cable 84 to enable communication between them. Additionally, see reference... Figure 15 The positioning screws 88 of the vibration testing equipment 12 can be tightened so that the screws engage with the positioning holes 86 formed in the lower connector member 68 of the test piece 14 to fix the lower connector member 68 in the test station 16.

[0060] See Figure 15After test piece 14 is installed in test station 16, the test can be initialized by actuating the motor control input 42, which signals the controller 40 to energize the electric drive assembly 32, thereby driving the upper member 26 in a reciprocating lateral motion relative to the base member 24 along axis 38. The electric drive assembly 32 can be controlled by the controller 40 in various ways in response to actuation of the motor control input 42. For example, when the motor control input 42 is actuated, the controller 40 can cause the electric drive assembly 12 to run for a predetermined period of time, such as thirty seconds, one minute, five minutes, or any other desired duration. Alternatively, the controller 40 can cause the electric drive assembly 32 to run until a signal from sensor 75 indicates that the fastener 72 and / or the thread-locking agent applied to the fastener 72 of test piece 14 has failed. The vibration testing device 12 can also be configured such that when the motor control input 42 is pressed, the controller 40 only causes the electric drive assembly 32 to operate, or it can be configured such that a first push of the motor control input 42 actuates the electric drive assembly 32, and a second push of the motor control input 42 prevents the electric drive assembly 32 from operating.

[0061] Figure 16 A schematic block diagram of the fastener testing system 10 is shown. As shown, the sensor 75 on the test piece 14 is operatively connected to the controller 40 of the vibration testing equipment 12 via a cable 84. The controller 40 is operatively connected to the motor control input 42 and the electric drive assembly 32 as described above, and is also operatively connected to the power supply 90 that supplies power to the vibration testing equipment 12. The controller 40 may also include a transmitter / receiver 92, such as a Bluetooth module, a wireless router, a cellular module, etc. Additionally, although described as a wireless transmitter, the transmitter / receiver 92 may provide a wired connection port such as a USB port.

[0062] When test piece 14 is tested, the electric drive assembly 32 is relative to... Figure 15 The base component 24 shown is driven by reciprocating lateral movement, as... Figure 15 The upper component 26 is shown, and data from the sensor 75 is provided to the controller 40. The user can maintain [the following information] during the test: Figure 1 The stabilizing handle 22 shown provides counteracting as Figure 15 The upper component 26 shown is a reaction lever for its reciprocating lateral movement. Data can be visualized on the display 44 by the controller 40, and / or can be used by the controller 40 to determine, for example... Figure 15The failure of the fastener 72 and the threadlocker applied to the fastener 72 is described above, so that the electric drive assembly 32 is deactivated as described. For example, sensor 75 can measure the force indicating the clamping load provided by fastener 72, so that the loss of clamping load can be detected by sensor force data. Display 44 can display digital data, or display 44 can simply provide an image indicating the loss of clamping load. For example, display 44 may include light-emitting diodes (LEDs) that change color from a first color to a second color when the clamping load is lost. Controller 40 can also use transmitter / receiver 92 to send data to remote device 94, such as a computer, tablet, mobile phone, etc., for further processing and / or display. After the test of test piece 14 is completed, for example, when data from sensor 75 indicates the loss of clamping load (which indicates the loosening of fastener 72 and / or the threadlocker applied to fastener 72), the electric drive assembly 32 can be deactivated, either automatically by controller 40 or manually by the user.

[0063] Looking back Figure 15 After test piece 14 has been tested in test station 16, test piece 14 can be removed from it using ejection system 21. Specifically, handle 50 can be removed from... Figure 15 The handle 50 is pushed in the direction 66 from the inoperable position to the ejected position. As the handle 50 moves, the shaft 52 rotates, and the first cam member 56 moves upward through the opening 58 into the test station 16, pushing upward on the test piece 16. This causes the test piece 14 to move upward out of the test cavity 27. The handle 50 can then be returned to the inoperable position. For example, in the ejection system 21, such as... Figure 13 In the case of the bias member 64 shown, the handle 50 can be easily released to allow the bias member 64 to return the ejection system 21 to an inoperable position.

[0064] Additional test pieces 14 can be tested in the same manner as described above. For example, if multiple test pieces 14 are prepared in the manner described above to test different thread fasteners, the multiple test pieces 14 can be tested sequentially in test station 16 in the manner described above. As described above, during each test, from such Figure 16 The data from the sensor 75 shown can be provided to, for example... Figure 16 The remote device 94 is shown. The remote device 94 can advantageously display and / or plot data from multiple tests together for comparison purposes.

[0065] See Figure 17The same reference numerals, representing the same elements, illustrate another embodiment of the fastener testing system 110. The fastener testing system 110 is similar to... Figure 1 The fastener testing system 10 shown is the same as the fastener testing system 110 except for the following aspects, and the fastener testing system 110 does not include the following. Figure 1 The ejection system 21 is shown. Therefore, the fastener testing system 110 includes a vibration testing device 112 and one or more test pieces 114. The vibration testing device 112 includes a test station 116 and a preparation station 118 arranged in the body 120. The vibration testing device 112 may also include a stabilizing handle 122 located at an end of the body 120.

[0066] Test piece 114 is combined with, for example Figure 1 The fastener testing system 10 shown is prepared in preparation station 118 and tested in testing station 116 in the same manner as described above. However, in order to remove the test piece 114 from preparation station 118 and testing station 116, the user or operator simply grasps the test piece 114 to be removed, for example, via sensor transmitter 178, and then pulls upward on the test piece 114, thereby removing the test piece 114 from the preparation station 118 or testing station 116 in which it is positioned. Except for the absence of... Figure 1 The ejection system 21 and fastener testing system 110 shown are as follows: Figure 1 The fastener testing system 10 shown is the same as that shown, and is similar to that shown. Figure 1 The fastener testing system 10 shown operates in the same manner, and therefore the structure and operation of the fastener testing system 110 will not be described in detail again.

[0067] The fastener testing systems 10, 110 of this disclosure advantageously provide a portable, stand-alone testing device for testing and comparing fasteners and adhesive thread fixatives applied to such fasteners. Stabilizing handles 22, 122 can be advantageously used to carry and transport vibration testing equipment 12, 112. Preparation stations 18, 118 and testing stations 16, 116 are advantageously contained within a single unit, which allows for the preparation and testing of interchangeable test pieces 14, 114 without waiting for the adhesive thread fixative to cure between tests and without the need for disassembly and / or assembly between tests to position new fasteners in the testing equipment. For example, multiple test pieces 14, 114 can be prepared several hours or days prior to the testing procedure or verification. Test pieces 14, 114 advantageously have a stepped design that prevents blockage of the vibration testing equipment 12, 112. Fastener testing systems 10, 110 can be advantageously coupled with remote device 94 to provide improved data capture and / or processing, for example, to provide a comparison of the strength of different viscous threadlockers being tested.

[0068] Although the principles of the systems and devices have been described herein, those skilled in the art should understand that such description is merely exemplary and not intended to limit the scope of the invention. As will be apparent to those skilled in the art, various changes and modifications can be made to the systems and devices described herein without departing from the spirit of the invention, and such changes and modifications are considered to be within the scope of this disclosure. Therefore, the exemplary embodiments described in the application documents are to be considered merely illustrative and not restrictive.
