Description
Technical Field
[0001] The present application relates to the technical field of detection equipment, and in particular to a handle stability detection device. Background Art
[0002] For containers such as water cups with handles, which include a main body and a handle that are fixed to each other, the handle may become detached from the main body, causing damage to the product, as users hold the handle at different angles during use. Therefore, during the production process, the stability and durability of the connection between the handle and the main body can be tested to ensure product quality.
[0003] In the prior art, the detection between the main body and the handle is mainly performed manually. Specifically, a water cup with a handle is first fixed on a mechanical torque meter, the handle is manually grasped by hand, and then the cup body is twisted with force to subject the handle to torque. When the pointer of the mechanical torque meter shows that it has reached a preset torque value, it needs to be maintained for a period of time, and then it is twisted again in the opposite direction with the same torque for the same time. During this period, the number of actions needs to be recorded and the state of the handle needs to be observed. After the preset number of tests, it is judged whether the combination stability and durability between the handle and the main body meet the requirements based on the condition between the handle and the main body.
[0004] However, during the above detection process, the detection operation is repeated many times, the user's manual operation intensity is large, and the detection efficiency is low. At the same time, the accuracy of the detection result will be affected by the uneven manual control torque and the error in holding time.
[0005] Therefore, how to test the combination stability and durability between the main body and the handle, reduce the intensity of manual operation, improve the detection efficiency, and ensure the accuracy of the detection results is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0008] During the detection, first place the water cup on the operating table, fix the cup body by the first fixing part, fix the handle by the second fixing part, and the controller controls the rotating part to drive so that the first fixing part rotates in the first direction relative to the second fixing part. When the torque value reaches the preset torque value, the controller controls the rotating part to keep the current torque value unchanged, so that the handle and the main body are kept at the current torque value for a preset time, and the first detection is completed. Then the controller controls the driving part to drive so that the first fixing part rotates in the second direction relative to the second fixing part. When the torque value reaches the preset torque value, the controller controls the rotating part to keep the current torque value unchanged, so that the handle and the main body are kept at the current torque value for a preset time, and the second detection is completed. Then the controller controls the rotating part to drive to perform the third detection. The third detection is the same as the first detection, and the fourth detection is the same as the second detection. This is repeated until the number of detections reaches the preset number of times and the detection is completed.

DETAILED DESCRIPTION
[0032] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0033] For parts with handles, including the main body and the handle, the handle is fixed to the main body, and the stability and durability of the combination between the handle and the main body need to be tested to ensure product quality. For example, a water cup includes a cup body and a handle, and the handle is fixed to the cup body. During use, the user holds the handle at different angles, which may cause the handle to separate from the cup body and damage the water cup.
[0034] An embodiment of the present application provides a handle stability detection device for detecting the combination stability and durability between a main body and a handle.
[0035] like Figure 1As shown, the handle stability detection device includes an operating table 1, a first fixing portion 4, a second fixing portion 5 and a rotating portion 3, wherein the first fixing portion 4 and the second fixing portion 5 are both arranged on the operating table 1, the first fixing portion 4 is used to be fixed to the main body, the second fixing portion 5 is used to be fixed to the handle, and the rotating portion 3 is used to drive the first fixing portion 4 to rotate relative to the second fixing portion 5.
[0036] The handle stability detection device also includes a controller, which is connected to the rotating part 3 by signal, which can be specifically connected by wire through a connecting line, or wirelessly connected by WiFi, Bluetooth, infrared, etc. The controller can send a control instruction to the rotating part 3 to control the rotating direction and number of rotations of the first fixed part 4 driven by the rotating part 3 relative to the second fixed part 5. At the same time, the controller can also control the holding time when the rotating part 3 drives the first fixed part 4 to rotate relative to the second fixed part 5 with a preset torque value.
[0037] In detail, during the detection, the water cup is first placed on the operating table 1, the cup body is fixed by the first fixing part 4, and the handle is fixed by the second fixing part 5. The controller controls the rotating part 3 to drive so that the first fixing part 4 rotates in the first direction relative to the second fixing part 5. When the torque value reaches the preset torque value, the controller controls the rotating part 3 to keep the current torque value unchanged, so that the handle and the main body are kept at the current torque value for a preset time, and then the first detection is completed. Then the controller controls the driving part to drive so that the first fixing part 4 rotates in the second direction relative to the second fixing part 5. When the torque value reaches the preset torque value, the controller controls the rotating part 3 to keep the current torque value unchanged, so that the handle and the main body are kept at the current torque value for a preset time, and then the second detection is completed. Then the controller controls the rotating part 3 to drive to perform the third detection. The third detection is the same as the first detection, and the fourth detection is the same as the second detection. This is repeated until the number of detections reaches the preset number of times and the detection is completed.
[0038] The first direction and the second direction are two opposite directions. When the first direction is a clockwise direction, the second direction is a counterclockwise direction. When the first direction is a counterclockwise direction, the second direction is a clockwise direction.
[0039] By controlling the driving action of the rotating part 3 through the controller, each detection can ensure that the main body and the handle maintain a preset torque value for a preset time. Compared with the manual operation solution, it can obviously simplify the manual operation and improve the detection efficiency. At the same time, it can also ensure the accuracy of parameters such as the preset torque value, holding time, and number of detections, thereby ensuring the accuracy of the test results, which is conducive to analyzing the combination stability and durability between the handle and the main body.
[0040] Specifically, how the controller is connected to the rotating part 3 signal to control the rotating part 3 to drive the first fixed part 4 to rotate relative to the second fixed part 5 in the direction of rotation, the number of rotations, and the preset duration of each detection at a preset torque value is a well-known prior art to those skilled in the art and will not be elaborated here to save space.
[0041] like Figure 1 As shown, the operating table 1 is further provided with a bracket 11, and the bracket 11 is further provided with a slideway 12 along the height direction, and the second fixing part 5 can slide to a suitable height along the slideway 12. For different products, the height at which the handle is fixed to the main body may be different, so the second fixing part 5 can be raised and lowered along the slideway 12, which can make the handle stability detection device suitable for the detection of more products, with good flexibility and a wide range of applications.
[0042] Specifically, there is no limitation on the specific structure of the slideway 12, which may be a slide groove, a bar hole, or a slide rail.
[0043] In this embodiment, the second fixing part 5 can slide up and down along the slideway 12 manually by an operator. Of course, the handle stability detection device can also include a lifting part, which is arranged on the operating table 1 and is used to drive the second fixing part 5 to move up and down along the slide. The lifting part can be a cylinder, a hydraulic cylinder, an electrode screw assembly, etc., and no specific restrictions are made here. In addition, in order to further simplify manual operation and improve detection efficiency, the lifting part can also be connected to the controller signal, and the controller controls the lifting part to drive the second fixing part 5 to move up and down.
[0044] like Figure 1 As shown, the handle stability detection device also includes a clamping part 2, which includes a power part 21, a connecting arm 22 and a rotating cover 23, wherein the connecting arm 22 can slide up and down along the slide 12 under the driving action of the power part 21, and drive the rotating cover 23 to move to abut and press against the top of the main body, thereby ensuring the stability of the main body in the installed state and avoiding deformation, damage, etc. of the main body due to uneven force.
[0045] The rotating cover 23 and the connecting arm 22 are rotatably connected, and specifically a bearing may be connected between the two to ensure rotation stability. When the rotating part 3 drives the main body to rotate, the rotating cover 23 can rotate together with the main body to avoid resistance to the rotation of the main body, thereby ensuring the accuracy of the detection result.
[0046] Specifically, there is no limitation on the specific structure of the power member 21. Figure 1As shown, the power member 21 includes a power motor 211, a driving wheel 212, a driven wheel (not shown in the figure) and a transmission belt 213, wherein the driving wheel 212 and the driven wheel are arranged at intervals on the bracket 11 along the height direction, the transmission belt 213 is ring-shaped and wound around the driving wheel 212 and the driven wheel, and is in a tensioned state, the connecting arm 22 is connected to any position of the transmission belt 213, the power motor 211 is arranged on the bracket 11 and is used to drive the driving wheel 212 to rotate forward and reverse. When the driving wheel 212 rotates, it can drive the transmission belt 213 to rotate, and then drive the connecting arm 22 to move up and down along the slide 12, thereby adjusting the height position of the rotating cover 23, so that the rotating cover 23 can stably abut against the top of the main body, thereby ensuring the stability of the main body during rotation.
[0047] Of course, in this embodiment, there is no limitation on the specific structure of the power member 21, and it can be set as a cylinder, a hydraulic cylinder, etc. provided on the bracket 11. When the power member 21 is set as a structure including a power motor 211, a driving wheel 212, a driven wheel, and a transmission belt 213, the driving stability can be ensured and accurate control is facilitated. In this embodiment, the transmission belt 213 can be a belt structure or a chain structure, etc., and no specific limitation is made here.
[0048] like Figure 2 As shown, the first fixing portion 4 includes a carrier 41, a first clamping member 42, a second clamping member 43, a driving member 44 and a transmission assembly, wherein the carrier 41 is used to place the main body, and the driving member 44 is used to drive the first clamping member 42 and the second clamping member 43 to move relative to each other. At the same time, during the relative movement of the first clamping member 42 and the second clamping member 43, the transmission assembly can also be used to make the two clamping members (the first clamping member 42 and the second clamping member 43) move synchronously to achieve mutual approach or distance.
[0049] Specifically, under the driving action of the driving member 44, combined with the action of the transmission assembly, the first clamping member 42 and the second clamping member 43 can approach each other at the same time and can respectively press against the outer wall of the main body from both sides to achieve clamping and fixing of the main body. Under the driving action of the driving member 44, combined with the action of the transmission assembly, the first clamping member 42 and the second clamping member 43 can move away from each other and can respectively detach from the main body from both sides.
[0050] Of course, two driving members 44 can also be provided, and these two driving members 44 are used to drive the first clamping member 42 and the second clamping member 43 respectively. The solution of only providing one driving member 44 and a transmission assembly can simplify the overall structure and reduce costs. The arrangement of the transmission assembly can also ensure the synchronization of the movement of the first clamping member 42 and the second clamping member 43, and can ensure that the main body is stably in a preset position of the carrier 41 (that is, the middle position of the two clamping members) when it is clamped and fixed. In this way, it can be ensured that the second fixing part 5 can be fixed to the handle. At the same time, it can also be ensured that when the rotating part 3 drives the first fixing part 4 to drive the main body to rotate, the main body is prevented from having a tendency to deviate due to being in an eccentric position, thereby ensuring the rotation stability of the main body.
[0051] In this embodiment, the driving member 44 drives the first clamping member 42 and the second clamping member 43 to move relative to each other. Specifically, the driving member 44 can only drive one of the clamping members to move, such as the driving member 44 drives the first clamping member 42 to move the first clamping member 42 toward or away from the second clamping member 43, or the driving member 44 drives the second clamping member 43 to move the second clamping member 43 toward or away from the first clamping member 42.
[0052] The driving member 44 drives one of the clamping members to move, and can drive the other clamping member to move through the transmission assembly. In this case, the driving member 44 can be set as a driving cylinder, an electrode wire rod assembly, etc. In order to ensure the stability of the spacing adjustment between the two clamping members, a guide structure can also be provided to provide guidance for the movement of the two clamping members. For example, the guide structure includes a guide rod, and the two clamping members can slide along the axial direction of the guide rod.
[0053] Alternatively, the driving member 44 may be configured as a telescopic member, the length of which may be adjusted by telescoping, and the two ends of the telescopic member in the length direction are respectively connected to the first clamping member 42 and the second clamping member 43, and the telescopic member can directly act on the two clamping members at the same time during the telescoping process, so that the two clamping members can move closer to or farther from each other. For example, the driving member 44 may be configured as a driving cylinder, which includes a cylinder body 441 and a piston rod 442, and the piston rod 442 is telescopic relative to the cylinder body 441 to adjust the overall length of the driving member 44, the cylinder body 441 is connected to one clamping member, and the piston rod 442 is connected to another clamping member. Specifically, the driving cylinder may be a pneumatic cylinder or a hydraulic cylinder.
[0054] The driving member 44 is set as a telescopic member. The driving member 44 can be connected to the two clamping members at the same time. The distance between the two clamping members can be directly adjusted by the extension and retraction of the telescopic member. The transmission component only needs to ensure that the two clamping members can move synchronously relative to the middle position, which simplifies the requirements for the transmission component. The driving member 44 does not need to extend beyond the two clamping members, which can reduce the occupied space and facilitate layout. At the same time, the two clamping members move along the extension and retraction direction of the telescopic member to achieve mutual approach or distance. The movement stability is good, and the overall structure can be simplified, making the overall structure more regular and effectively reducing costs.
[0055] Further, such as Figure 3-Figure 6 As shown, the transmission assembly includes a rotating shaft 46, a first rod group and a second rod group, wherein the first rod group and the second rod group are symmetrically arranged on both sides of the radial direction of the rotating shaft 46, and the first clamping member 42 and the second clamping member 43 are also symmetrically arranged about the radial direction of the rotating shaft 46.
[0056] The first rod group includes a first connecting rod 471 and a first pulling rod 472, wherein the first connecting rod 471 and the first pulling rod 472 are hingedly connected, one end of the first connecting rod 471 away from the first pulling rod 472 is fixed to the rotating shaft 46 and can rotate coaxially with the rotating shaft 46, and one end of the first pulling rod 472 away from the first connecting rod 471 is hingedly connected to the first clamping member 42. The second rod group includes a second connecting rod 481 and a second pulling rod 482, wherein the second connecting rod 481 and the second pulling rod 482 are hingedly connected, one end of the second connecting rod 481 away from the second pulling rod 482 is fixed to the rotating shaft 46 and can rotate coaxially with the rotating shaft 46, and one end of the second pulling rod 482 away from the second connecting rod 481 is hingedly connected to the second clamping member 43. Preferably, as Figure 6 As shown, the first pull rod 472 and the second pull rod 482 are arc-shaped rods.
[0057] The detection assembly further includes an adjustment block 6, which is provided with a coaxially arranged shaft hole 61 and a circular arc slideway 62, the rotating shaft 46 is rotatably arranged in the shaft hole 61, and a slider is further arranged at the hinge between the first connecting rod 471 and the first pull rod 472, and the slider can slide along the circular arc slideway 62. The circular arc slideway 62 can be a circular arc hole or a circular arc groove, which is not specifically limited here.
[0058] The adjustment block 6, the rotating shaft 46, the first pull rod 472, and the second pull rod 482 are all located below the platform 41, and the first clamping member 42 and the second clamping member 43 can pass through the platform 41 and clamp the main body from above the platform 41. In other words, the transmission assembly is located below the platform 41, and only two clamping members extend above the platform 41 and are used to cooperate with or disengage from the main body. Compared with the solution of arranging the transmission assembly above the platform 41, such a setting can simplify the overall structure, make the overall structure more regular, and also avoid the interference of the transmission assembly with the placement of the main body.
[0059] In detail, taking the driving member 44 as a telescopic member as an example, Figure 3 and Figure 6 In the state shown, when it is necessary to increase the distance between the two clamping members, the driving member 44 is extended, so that the first clamping member 42 and the second clamping member 43 move to both sides respectively, and the distance between them increases. In this process, the first clamping member 42 drives the first pull rod 472 to move toward one side of the first clamping member 42, and the first pull rod 472 drives the end of the first connecting rod 471 away from the rotating shaft 46 to move toward the side of the first clamping member 42. The slider 45 can slide clockwise along the arc-shaped slide 62, and the first connecting rod 471 rotates clockwise and drives the rotating shaft 46 to rotate clockwise. At the same time, the second clamping member 43 drives the second pull rod 482 to move toward one side of the second clamping member 43, and the second pull rod 482 drives the end of the second connecting rod 481 away from the rotating shaft 46 to move toward the second clamping member 43, and the second connecting rod 481 rotates clockwise, driving the rotating shaft 46 to rotate clockwise.
[0060] Since the rotating shaft 46, the first connecting rod 471 and the second connecting rod 481 are relatively fixed, the three rotate synchronously, the first rod group and the second rod group are symmetrically arranged about the radial direction of the rotating shaft 46, and the action states of the first rod group and the second rod group on both sides of the rotating shaft are consistent. Therefore, the first pull rod 472 and the second pull rod 482 have the same action and opposite directions, and the spacing between the rotating shaft 46 and the first clamping member 42 and the spacing between the rotating shaft 46 and the second clamping member 43 are the same, thereby ensuring that the two clamping members can move synchronously to both sides, and the rotating shaft 46 always remains in the center position between the two clamping members.
[0061] When it is necessary to reduce the distance between the two clamping members, the driving member 44 is shortened, and the distance between the two clamping members is reduced. The actions of the first rod group and the second rod group are opposite to the actions when the distance between the two clamping members is increased. The rotating shaft 46 rotates counterclockwise and always remains in the center position between the two clamping members. To save space, it will not be repeated here.
[0062] It should be noted that the above-mentioned "clockwise" and "counterclockwise" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.
[0063] The setting of the arc-shaped slide 62 and the slider 45 can provide guidance and limitation for the movement of the first rod group, so that the hinge between the first connecting rod 471 and the first pull rod 472 can only slide along the arc-shaped slide 62, and the first pull rod 472 and the second pull rod 482 are both arc-shaped pull rods, ensuring that the first rod group and the second rod group can move smoothly and avoid jamming.
[0064] Taking the action of the first rod group as an example when the driving member 44 drives the two clamping members to move toward each other, if the arc-shaped slide 62 and the slider 45 are not provided, the first pull rod 472 can also push the first connecting rod 471 to rotate, and the first clamping member 42 and the second clamping member 43 can also achieve synchronous movement toward the closer side. However, in this process, since the first pull rod 472 and the first clamping member 42 are also hingedly connected, and the first pull rod 472 and the first connecting rod 471 are also hingedly connected, the first pull rod 472 is roughly moved as a whole toward one side of the rotating shaft 46. The tangential force acting on the first connecting rod 471 to rotate it is relatively small. In order to enable the first connecting rod 471 to rotate around the axis of the rotating shaft 46, the driving force required by the driving member 44 is relatively large.
[0065] The arrangement of the arc-shaped slide 62 and the slider 45 can limit the movement of the first pull rod 472 toward one end of the first connecting rod 471. When the driving member 44 drives the two clamping members to approach each other, the first pull rod 472 slides along the arc-shaped slide 62 toward one end of the first connecting rod 471, so that the component force of the first pull rod 472 on the first connecting rod 471 in the tangential direction of the arc-shaped slide 62 is relatively large, which makes it easier to rotate the first connecting rod 471, thereby reducing the driving force of the driving member 44 while achieving the purpose of rotating the first connecting rod 471 around the axis of the rotating shaft 46, thereby reducing the driving force requirement of the driving member 44 and reducing the cost.
[0066] like Figure 7 and Fig.11As shown, the adjustment block 6 is provided with only one arc-shaped slideway 62, and only the first rod group is provided with a slider 45 that can slide along the arc-shaped slideway 62. Of course, the adjustment block 6 can also be provided with two arc-shaped slideways 62, which are radially symmetrically arranged about the rotating shaft 46, and the first rod group and the second rod group are respectively provided with sliders 45, and the two sliders 45 are respectively and correspondingly slidably arranged in the two arc-shaped slideways 62, thereby reducing the driving force requirements of the driving member 44 while ensuring stability. When the adjustment block 6 is provided with only one arc-shaped slideway 62 and only the first rod group is provided with a slider 45, the overall structure can be simplified, the molding process of the adjustment block 6 can be simplified, and the cost can be reduced.
[0067] like Figure 3 As shown, taking the example of the cylinder body 441 being connected to the second clamping member 43 and the piston rod 442 being connected to the first clamping member 42, the second clamping member 43 is provided with a first guide hole 421, and the piston rod 442 passes through the first guide hole 421 and can slide along the axial direction of the first guide hole 421 relative to the second clamping member 43. The first guide hole 421 can provide guidance for the movement of the piston rod 442. Specifically, the number of the first guide holes 421 can be two, and the number of the piston rods 442 is also correspondingly set to two, so that the guiding effect is stable and relative rotation is avoided, thereby ensuring the driving stability of the driving member 44 and the movement stability of the two clamping members.
[0068] When the distance between the first clamping member 42 and the second clamping member 43 is reduced to the point where the two members abut and clamp the main body from both sides, the length of the telescopic member remains unchanged, keeping the main body in a clamped state, and the relative positions of the two clamping members and the rotating shaft 46 are stabilized by the two rod groups respectively. The rotating motor of the rotating part 3 can be directly connected to the rotating shaft 46 and drive the rotating shaft 46 to rotate, thereby driving the first clamping member 42, the second clamping member 43, the driving member 44 and the main body to rotate together.
[0069] In this case, the adjustment block 6 may rotate with the first fixed part 4 or not. When the adjustment block 6 rotates with the first fixed part 4, after the two clamping members clamp and fix the main body, the synchronous rotation between the rotating shaft 46 and the adjustment block 6 can be achieved through the connection structure. There is no restriction on the specific structure of the connection structure. The connection can be achieved by clamping or by electromagnetic means. Specifically, it can be a structure arranged between the slider and the arc-shaped slideway 62, a structure connected between the driving member 44 and the adjustment block 6, or a structure connected between the clamping member and the adjustment block 6. No further details are given here. When the adjustment block 6 does not rotate with the first fixed part 4, the length of the arc-shaped slideway 62 can be increased. When the rotating part 3 drives the rotating shaft 46 to rotate, the slider 45 slides within a part of the arc-shaped slideway 62. At this time, the adjustment block 6 can be fixed to the operating table 1.
[0070] Alternatively, the adjustment block 6 may be provided with a second guide hole 63 (such as Fig.11 As shown in FIG. 6 , the telescopic member passes through the second guide hole 63, and the two ends of the telescopic member extend out of the second guide hole 63 and are respectively connected to the two clamping members (as shown in FIG. Fig. 9 and Fig.10 As shown in the figure, at least one side wall of the second guide hole 63 is provided with the above-mentioned shaft hole 61 and the arc-shaped slideway 62. The lengths of the two ends of the telescopic member extending out of the second guide hole 63 are the same and synchronously adjustable. The second guide hole 63 can provide guidance for the telescopic member. At the same time, it can also provide support for the telescopic member to ensure the stability of the telescopic effect of the telescopic member.
[0071] In this case, when the main body is clamped between the first clamping member 42 and the second clamping member 43, the relative positions of the telescopic member, the main body, the two rod groups and the rotating shaft 46 are stable, and because the second guide hole 63 can provide guidance for the telescopic member, the telescopic member cannot rotate relative to the adjusting block 6. At this time, the rotating motor of the rotating part 3 can directly drive the rotating shaft 46 to rotate, and can also directly drive the adjusting block 6 to rotate, so as to realize the overall rotation of the first fixed part 4.
[0072] In this embodiment, there is no limitation on the specific structure of the two clamping members. Figure 8 and Fig.12 As shown, the carrier 41 is provided with a first strip hole 411 and a second strip hole 412, wherein the length directions of the first strip hole 411 and the second strip hole 412 are parallel or colinear, the first clamping member 42 passes through the first strip hole 411 and can move along the length direction of the first strip hole 411, and the second clamping member 43 passes through the second strip hole 412 and can move along the length direction of the second strip hole 412. The first strip hole 411 and the second strip hole 412 can be as follows Figure 8 The circumferentially closed hole shown can also be Fig.12 Any structure with openings in the circumferential direction shown is acceptable.
[0073] Taking the first clamping member 42 as an example, the first clamping member 42 includes a matching section, a guide section and a connecting section arranged in sequence, wherein the connecting section is connected to the telescopic member, the guide section passes through the first strip hole 411, the matching section is located above the carrier 41, and is used to abut against the main body, and the matching section has a curved surface on one side facing the second clamping member 43, which is convenient for increasing the abutment area between it and the main body to ensure clamping stability. The structure of the second clamping member 43 can refer to the structure of the first clamping member 42, and is not specifically limited here.
[0074] In this embodiment, there is no limitation on the specific structure of the adjustment block 6, which may be as follows: Figure 7 The adjustment block 6 shown is a cylindrical structure, and can also be Fig.12The adjustment block 6 shown is a square structure, but may also be other regular or irregular structures.
[0075] The rotating part 3 includes a rotating motor and an angle measuring member 31, wherein the rotating motor is used to drive the first fixing part 4 to rotate, and the rotating motor can also be used to drive the angle measuring member 31 to rotate. Figure 2 As shown, the angle measuring member 31 is provided with an angle scale 32 along the circumference of the rotating shaft 46, and the operating table 1 is provided with an indicating structure. Figure 2 As shown, the angle measuring member 31 may be a cylindrical structure coaxial with the rotating shaft 46 and provided with an angle scale 32 on its outer peripheral wall, or the angle measuring member 31 may be provided with an indicating structure, and the operating table 1 may be provided with an angle scale 32 along the circumference of the rotating shaft 46, wherein the indicating structure may be a pointer or an indicating line. In the process of the rotating part 3 driving the first fixing part 4 to rotate, the rotation angle of the main body part may be known through the indicating structure and the angle scale 32.
[0076] For cups whose handles may be deformed during the detection process, the cup body will rotate during the detection process, and the specific rotation angle of the main body can be known through the angle scale 32 and the indicating structure, thereby knowing the deformation degree of the handle, so as to facilitate the analysis of the combination stability and durability between the handle and the main body.
[0077] like Figure 2 As shown, the rotating part 3 is also provided with a protruding piece 33, which is fixed to the above-mentioned angle measuring piece 31 and can rotate together with the first fixed part 4 under the driving action of the rotating motor. The operating table 1 is also provided with two sensing pieces 7. When the driving part drives the first fixed part 4 to rotate, the protruding piece 33 swings between the two sensing pieces 7. If the protruding piece 33 abuts against the sensing piece 7, the rotating part 3 stops driving.
[0078] During normal detection, when the rotating part 3 drives the first fixed part 4 to rotate, the second fixed part 5 does not move, and the rotation of the first fixed part 4 and the main body is limited by the handle. The protrusion 33 does not swing or the protrusion 33 can only swing within a small angle range between the two sensing parts 7. The protrusion 33 does not trigger the sensing part 7. When a fault occurs, such as the handle and the main body are detached or the handle is damaged, the rotation of the main body is no longer restricted, and the rotation amplitude becomes larger. When the protrusion 33 triggers the sensing part 7, the rotating part 3 stops driving in time to avoid the rotating part 3 continuing to drive the main body to rotate and cause danger, thereby improving safety.
[0079] In this embodiment, there is no specific limitation on the sensing element 7 , and the protrusion 33 can trigger the sensing element 7 by contact or by electromagnetic induction.
[0080] In this embodiment, there is no limitation on the specific structure of the second fixing part 5. For example, the second fixing part 5 includes two clamping jaws, and the two clamping jaws can move relatively. One of the clamping jaws is provided with a through hole and the other is provided with a threaded hole. A bolt passes through the through hole and cooperates with the threaded hole to adjust the distance between the two clamping jaws to achieve clamping, fixing and disengagement. Alternatively, the second fixing part 5 can also be set as a robot to achieve the purpose of grasping and releasing the handle.
[0081] like Figure 1 As shown, the operating table 1 is also provided with a switch 14 and an emergency stop button 13, wherein when the emergency stop button 13 is pressed, an emergency stop is detected, and each driving component (including the rotating part 3, the power motor 211, the lifting part, etc.) stops driving operation, so as to ensure safety in the event of an emergency failure. The switch 14 refers to a start switch 14 for starting detection. When the emergency stop button 13 is not pressed and the switch 14 is pressed, the detection starts. There are two switches 14, which are respectively located on both sides of the emergency stop button 13. The start is started only when the two switches 14 are pressed at the same time, otherwise it will not start. Such a setting can further ensure safety and avoid danger caused by the start of detection due to accidental touching of the switch 14.
[0082] The operating table 1 is also provided with a display panel 15, which is connected to the controller signal. The control command can be input to the controller through the display panel 15. The control command includes information such as a preset torque value, a preset number of times, and a preset duration. Each parameter can be set according to different components to be detected. The controller controls the rotating part 3 and other components according to the control command, which has good flexibility. The display panel 15 can also be used to display various parameters and detection results, current detection progress, detection status, etc.
[0083] Specifically, the display panel 15 can be one or more panels, such as a program control panel, a parameter display panel, etc., wherein the program control panel is used to input control instructions, and the torque control display panel 15 is used to display the torque value and can control the rotating part 3. Specifically, there is no requirement for the location of each display panel 15. How to connect with the controller signal, how to input control instructions, and how to display various information are existing technologies well known to those skilled in the art, and will not be repeated here to save space.
[0084] The operating table 1 is also provided with a prompt device 16, which is connected to the controller signal. When the number of rotations reaches a preset number or a fault is detected, the controller controls the prompt device 16 to send a prompt signal to the operator, so that the operator can know the situation in time and deal with it in time. The prompt signal can be at least one of a text signal, a sound signal, a light signal, etc.
[0085] Specifically, the detection process of the product by the handle stability detection device is as follows:
[0086] Before the test, the main body is placed on the platform 41, and the power motor 211 drives the connecting arm 22 to move downward along the slide 12 until the rotating cover 23 abuts against the top of the main body, and then the driving member 44 is driven to make the first clamping member 42 and the second clamping member 43 approach each other and abut against the main body placed on the platform 41 from both sides, and the second fixing member 5 is fixed to the handle, and the control parameters are input through the display panel 15. After the program is set, the emergency stop button 13 is released, and the two switches 14 are pressed at the same time, and the test starts. The rotating part 3 rotates the first fixing part 4 so that the main body rotates in a first direction relative to the handle and maintains a preset torque value for a preset time. Then the rotating part 3 rotates the first fixing part 4 so that the main body rotates in a second direction relative to the handle and maintains a preset torque value for a preset time. This is repeated until the preset number of experiments is reached, the test is ended, and the prompt device 16 sends a prompt signal.
[0087] In the description of this application, it should be understood that the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
[0088] The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
