[0035] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0036] The following describes embodiments of the flexible abutment mechanism and welding device provided by the present invention in conjunction with the accompanying drawings.
[0037] In one embodiment of the flexible abutment mechanism of the present invention, Figure 1 to Figure 3As shown, the flexible abutment mechanism includes a first mounting member 10, a second mounting member 20, an elastic support assembly 30 and a guide assembly 40. The first mounting member 10 and the second mounting member 20 are arranged at intervals, the first mounting member 10 is used to connect with the driving mechanism, and the side of the second mounting member 20 facing away from the first mounting member 10 is used to press the target object. The elastic support assembly 30 includes a plurality of elastic members 31, each elastic member 31 is arranged between the first mounting member 10 and the second mounting member 20, and the two ends are respectively connected to the first mounting member 10 and the second mounting member 20. The guide assembly 40 includes a main body 41 and a floating joint part 42. The main body 41 is arranged on one of the first mounting member 10 and the second mounting member 20, and the floating joint part 42 is arranged on the other. The floating joint part 42 is connected to the main body 41, and the floating joint part 42 and the main body 41 can swing relative to each other at the connection between the two.
[0038] In this embodiment, the first mounting member 10 and the second mounting member 20 may be plate-shaped, and the plate surfaces of the two may be arranged in parallel. The first mounting member 10 is connected to a driving mechanism, and the driving mechanism can act on the flexible abutment mechanism as a whole through the first mounting member 10, drive the flexible abutment mechanism to move, and make the flexible abutment mechanism approach the target object, contact the target object, and press the target object to perform a welding process or other processes on the target object. The second mounting member 20 is located on the side of the flexible abutment mechanism facing the target object, and the second mounting member 20 is pressed against the target object while the flexible abutment mechanism continues to approach the target object. Specifically, the second mounting member 20 may directly contact the target object, or a special crimping member 2 (such as a crimping member 22) may be provided on the side of the second mounting member 20 facing the target object. Figure 4 and Figure 5 as shown), used to press the target object tightly.
[0039] The elastic member 31 may be a spring, which is located between the first mounting member 10 and the second mounting member 20. The distance between the first mounting member 10 and the second mounting member 20 is set to be smaller than the length of the spring in a natural state, that is, in this embodiment, in a normal state, the spring is in a compressed state, and its two ends abut against the first mounting member 10 and the second mounting member 20, and the first mounting member 10 and the second mounting member 20 are subjected to the elastic force of the spring.
[0040] As for the first mounting member 10 and the second mounting member 20, they can overcome the elastic force of the elastic member and make the distance between them smaller. In this embodiment, a plurality of elastic members 31 are arranged in the elastic support assembly 30. It can be understood that the plurality of elastic members 31 are arranged at different positions. For example, Figure 1 and Figure 2In the structure shown, there are four elastic members 31, which are respectively arranged at the four corners of the first mounting member 10 and the second mounting member 20. In this case, when the external forces applied to the positions of different elastic members 31 are different, the compression states of the multiple elastic members 31 will show differences. For example, the length of some elastic members 31 will be compressed shorter, and the distance between the first mounting member 10 and the second mounting member 20 will be smaller here; while for other elastic members 31, the external forces applied to them are smaller, and their lengths will be longer, and the distance between the first mounting member 10 and the second mounting member 20 will be larger here. In combination with this embodiment, the first mounting member 10, which is usually connected to the external driving mechanism, is fixed, and the second mounting member 20 is used to directly or indirectly contact the target object. The difference in the distance between the first mounting member 10 and the second mounting member 20 at different positions is mainly reflected in whether the second mounting member 20 is tilted and the tilt size state. Under the action of multiple elastic members 31, the tilted state of the second mounting member 20 can match the surface on which the target object is placed. For example, when the surface on which the target object is placed is intact and not worn and tilted, the second mounting member 20 can maintain a standard plane state (the first mounting member 10 and the second mounting member 20 are parallel, and the distance between the two at different positions is consistent). When the surface on which the target object is placed is worn and tilted, the second mounting member 20 can be adjusted to a state that is not parallel to the first mounting member 10, but tilted relative to the first mounting member 10, and matches the surface on which the target object is placed (usually parallel to the surface on which the target object is placed).
[0041] As for the guide assembly 40, its floating joint part 42 and the main body part 41 are rotatably connected. When the state of the second mounting member 20 relative to the first mounting member 10 changes, the floating joint part 42 and the main body part 41 can swing to adapt to the change. For example, when the second mounting member 20 changes from a state parallel to the first mounting member 10 to a state inclined relative to the first mounting member 10, the floating joint part 42 and the main body part 41 swing relative to each other, which can avoid limiting and hindering the change of the state of the second mounting member 20 relative to the first mounting member 10, thereby ensuring the smooth realization of the change of the state of the second mounting member 20 relative to the first mounting member 10, so that the second mounting member 20 can achieve a good match with the surface where the target object is placed.
[0042] In one embodiment of the flexible abutment mechanism, the main body 41 includes a linear bearing.
[0043] By setting the main body 41 as a linear bearing, the function and effect of length change can be achieved for the guide assembly 40, and the change in the length of the guide assembly 40 can adapt to the change in the distance between the first mounting member 10 and the second mounting member 20. Specifically, when the external force applied to the elastic support assembly 30 as a whole becomes larger and the length of its multiple elastic members 31 becomes shorter, the distance between the first mounting member 10 and the second mounting member 20 becomes smaller. At this time, the length of the guide assembly 40 can be synchronously reduced by the linear bearing; conversely, when the external force applied to the elastic support assembly 30 as a whole becomes smaller and the length of its multiple elastic members 31 becomes longer, the distance between the first mounting member 10 and the second mounting member 20 becomes larger. At this time, the length of the guide assembly 40 can be synchronously increased by the linear bearing.
[0044] In an alternative embodiment, the main body 41 is slidably connected to the first mounting member 10 or the second mounting member 20 where it is located. This arrangement can change the length of the main body 41 located inside the first mounting member 10 and the second mounting member 20 (the portion between the first mounting member 10 and the second mounting member 20), thereby adapting to the change in the distance between the first mounting member 10 and the second mounting member 20. Specifically, when the distance between the first mounting member 10 and the second mounting member 20 increases, the main body 41 slides inside the first mounting member 10 and the second mounting member 20, and vice versa, it slides outside the first mounting member 10 and the second mounting member 20, thereby achieving the same beneficial effects as the above-mentioned linear bearing embodiments, which will not be repeated.
[0045] In another alternative embodiment, the floating joint portion 42 is slidably connected with the first mounting member 10 or the second mounting member 20. This arrangement can change the length of the floating joint portion 42 located in the first mounting member 10 or the second mounting member 20, thereby adapting to the change in the distance between the first mounting member 10 and the second mounting member 20. The principle and effect are basically the same as those of the above embodiment and will not be described in detail.
[0046] In one embodiment of the flexible abutment mechanism, the flexible abutment mechanism further includes an adjustment assembly 50, and the adjustment assembly 50 includes a plurality of adjustment rods 51. Each adjustment rod 51 includes a fixed portion 511 and a movable portion 512 connected to each other, and the movable portion 512 can be extended and retracted relative to the fixed portion 511 in the length direction of the adjustment rod 51; one of the fixed portion 511 and the movable portion 512 is connected to the first mounting member 10, and the other is connected to the second mounting member 20. The plurality of adjustment rods 51 are respectively connected to different positions of the first mounting member 10 and the second mounting member 20.
[0047] In this embodiment, taking the example that the fixed portion 511 is disposed on the second mounting member 20 and the movable portion 512 is disposed on the first mounting member 10, the fixed portion 511 is slidably connected to the second mounting member 20, or the movable portion 512 is slidably connected to the first mounting member 10, or the fixed portion 511 is slidably connected to the movable portion 512. Figure 1 and Figure 2 In the structure shown, the fixed portion 511 and the movable portion 512 are threadedly connected; the fixed portion 511 is arranged on the second mounting member 20 and remains fixed to the second mounting member 20 (the two do not slide relative to each other, etc.); and the movable portion 512 is connected to the first mounting member 10, but can be relatively slidably connected to the first mounting member 10.
[0048] In this case, the maximum distance between the first mounting member 10 and the second mounting member 20 can be adjusted by setting the telescopic state between the fixed portion 511 and the movable portion 512 of the plurality of adjusting rods 51 in the adjusting assembly 50. Specifically, when the distance that the movable portion 512 extends outward relative to the fixed portion 511 is adjusted to be larger, the distance between the first mounting member 10 and the second mounting member 20 can also be correspondingly increased; conversely, when the distance that the movable portion 512 extends outward relative to the fixed portion 511 is adjusted to be smaller, the distance between the first mounting member 10 and the second mounting member 20 can also be correspondingly reduced.
[0049] In this embodiment, for the multiple adjustment rods 51 of the adjustment assembly 50, it is easy to understand that the multiple adjustment rods 51 are arranged at different positions of the first mounting member 10 and the second mounting member 20, such as Figure 1 and Figure 2 As shown, the adjustment assembly 50 includes four adjustment rods 51, and the four adjustment rods 51 are respectively arranged at the four corners of the first mounting member 10 and the second mounting member 20. By making different arrangements of different adjustment rods 51, the lengths of the movable portions 512 extending outward relative to the fixed portions 511 of the different adjustment rods 51 are made the same or different, so that the maximum distances of the first mounting member 10 and the second mounting member 20 at different positions can be made the same or different. Due to the elastic force of the multiple elastic members 31 in the elastic support assembly 30 on the first mounting member 10 and the second mounting member 20, when no external force is applied, the distance between the first mounting member 10 and the second mounting member 20 will be maintained at the maximum distance that the two can reach. Therefore, according to the different states of the multiple adjustment rods 51 in the adjustment assembly 50, the relative state of the first mounting member 10 and the second mounting member 20 can be controlled, specifically including the overall distance between the first mounting member 10 and the second mounting member 20, whether the first mounting member 10 and the second mounting member 20 are parallel or inclined, and the relative inclination angle between the first mounting member 10 and the second mounting member 20.
[0050] In terms of actual implementation, when the surface on which the target object is placed becomes worn and tilted, and when continued wear causes a greater degree of tilt, the length of the movable portion 512 in the multiple adjustment rods 51 extending outward can be controlled to adjust the inclination angle of the second mounting member 20 relative to the first mounting member 10, so that the second mounting member 20 matches the surface on which the target object is placed, so that the target object can be well pressed and secured when the flexible abutment mechanism approaches the target object and contacts the target object.
[0051] In a further embodiment of the flexible abutment mechanism, there are multiple adjustment rods 51 , and at least one elastic member 31 is disposed at each adjustment rod 51 .
[0052] In this embodiment, by providing a plurality of adjustment rods 51, the distance between the first mounting member 10 and the second mounting member 20 at different positions can be more accurately controlled, and the second mounting member 10 can have more tilting states relative to the first mounting member 10, thereby helping to make the second mounting member 20 more compatible with the surface on which the target object is placed. At the same time, an elastic member 31 is provided at each adjustment rod 51, so that the elastic force of the elastic member 31 on the first mounting member 10 and the second mounting member 20 can be as large as possible at the position where the adjustment rod 51 is located, so that the distance between the first mounting member 10 and the second mounting member 20 can reach the maximum distance defined by the adjustment rod 51, thereby helping to make the tilting state of the second mounting member 20 relative to the first mounting member 10 more accurate and consistent with the set state.
[0053] In one embodiment of the flexible abutment mechanism, Figure 2 As shown, a plurality of mounting holes 101 are provided on the first mounting member 10, and the plurality of mounting holes 101 respectively correspond to a plurality of adjusting rods 51; each adjusting rod 51 is correspondingly inserted into the corresponding mounting hole 101, and the aperture of the mounting hole 101 is larger than the diameter of the adjusting rod 51 inserted in the mounting hole 101.
[0054] In this embodiment, by setting the hole diameter of the mounting hole 101 to be larger than the diameter of the adjusting rod 51, there is a clearance when the adjusting rod 51 is inserted into the mounting hole 101. The clearance can adapt to the inclination of the second mounting member 20 relative to the first mounting member 10, thereby avoiding restrictions and obstructions on the change of the inclination state of the second mounting member 20.
[0055] In another embodiment of the flexible abutment mechanism, each of the adjustment rods 51 may also not distinguish and include a movable part and a fixed part respectively. The adjustment rod 51 as a whole is connected to the first mounting member 10 and the second mounting member 20, and the connection between the adjustment rod 51 and at least one of the first mounting member 10 and the second mounting member 20 is a movable connection, and the movable connection has a variable connection depth, that is, the connection depth of the adjustment rod 51 relative to the first mounting member 10 and the second mounting member 20 can be increased or decreased, that is, the portion of the adjustment rod 51 connected to the first mounting member 10 can be screwed in or inserted into the first mounting member 10 or the side of the first mounting member 10 facing away from the second mounting member 20 more or less, or the portion of the adjustment rod 51 connected to the second mounting member 20 can be screwed in or inserted into the second mounting member 20 or the side of the second mounting member 20 facing away from the first mounting member 10 more or less. Thus, in the above manner, the distance between the adjustment rod 51 and the first mounting member 10 and the second mounting member 20 can be adjusted.
[0056] In this embodiment, the adjusting rod 51 can be specifically a manual screw, one end of which is, for example, screwed to the first mounting member 10, and the change in depth on one side of the first mounting member 10 is achieved by screwing, and the other end can be in contact with the second mounting member 10. In this way, when adjusting the adjusting rod 51, it is mainly achieved by manually rotating the adjusting rod 51 relative to the first mounting member 10. Of course, in the above-mentioned embodiment, the adjusting rod 51 can also include a driving part and a lead screw; the driving part can be, for example, a motor, which is connected to the lead screw and is used to drive the lead screw to rotate; the lead screw is screwed to one of the first mounting member 10 and the second mounting member 20, and when the lead screw rotates, the depth of the lead screw on one side of the first mounting member 10 or the second mounting member 20 is adjusted.
[0057] In one embodiment of the flexible abutment mechanism, the flexible abutment mechanism further includes a plurality of displacement sensors 60, the number of the displacement sensors 60 is not less than the number of the elastic members 31, and at least one displacement sensor 60 is provided at each elastic member 31. The displacement sensor 60 has a retractable probe 61. The main body of the displacement sensor 60 is fixedly arranged on the first mounting member 10, and the head end of the probe 61 abuts against the second mounting member 20; or, the main body of the displacement sensor 60 is fixedly arranged on the second mounting member 20, and the head end of the probe 61 abuts against the first mounting member 10.
[0058] by Figure 1 and Figure 2As shown in the example, the main body of the displacement sensor 60 is arranged on the first mounting member 10, and the head end of the probe rod 61 is in contact with the second mounting member 20. Since the head end of the probe rod 61 is in contact with the second mounting member 20, the probe rod 61 can adapt to the change in the distance between the first mounting member 10 and the second mounting member 20 at its position and extend and retract. According to the extension and retraction range of the probe rod 61, the distance between the first mounting member 10 and the second mounting member 20 at the position can be determined, thereby helping to determine the degree of compression of the elastic member 31 at the position. According to the change in the degree of compression of the elastic member 31, it can be determined whether the deviation between the actual tilt state of the second mounting member 10 and the tilt state it should have exceeds the preset value. According to the result, it can be further determined that the tilt angle caused by further wear of the surface where the target object is placed exceeds the predetermined range.
[0059] Specifically, the displacement sensor 60 can perform detection each time the target object is pressed and fixed. If the distance between the first mounting member 10 and the second mounting member 20 detected by the displacement sensor 60 is within a predetermined range, it means that in the current state of the adjustment component 50, the second mounting member 20 can well press and fix the target object, which means that the wear of the surface on which the target object is placed does not cause tilting, or the resulting tilting is within the range covered by the current state of the adjustment component 50. If the distance between the first mounting member 10 and the second mounting member 20 detected by a certain displacement sensor 60 exceeds the predetermined range, it means that the wear of the surface on which the target object is placed causes the surface on which the target object is placed to tilt or further tilt beyond the range covered by the current state of the adjustment component 50. At this time, the adjustment component 50 needs to be adjusted. Through the adjustment, the tilting state of the second mounting member 20 relative to the first mounting member 10 is changed and matches the tilting state of the surface on which the target object is placed. It is understandable that after each adjustment of the adjustment component 50, the target object compression can be calibrated; specifically, the distance that the probe rods 61 of the plurality of displacement sensors 60 extend outward when the target object is compressed is determined, that is, the distance between the first mounting member 10 and the second mounting member 20 at their locations. This parameter reflects the compressed state of the elastic member 31. When the target object is subsequently compressed, the data detected by the displacement sensor 60 is compared with the calibrated data. If the difference between the two exceeds the set value, it means that the tilt state of the surface on which the target object is placed has changed due to wear, and the adjustment component 50 needs to be adjusted again to match the new tilt state of the surface on which the target is placed.
[0060] In an alternative embodiment of the flexible abutment mechanism, the flexible abutment mechanism further includes a plurality of first pressure sensors, and at least one end of each elastic member 31 is provided with a first pressure sensor.
[0061] In this embodiment, the first pressure sensor can detect the elastic force and compression state of each elastic member 31, and the compression state of the elastic member 31 reflects the distance between the first mounting member 10 and the second mounting member 20 at its position. In this way, the first pressure sensor in this embodiment can achieve the functions and effects of the displacement sensor 60 in the aforementioned embodiment, which will not be repeated here.
[0062] In practice, the elastic force and compressed state of the elastic member 31 do not respond obviously to slight changes in the distance between the first mounting member 10 and the second mounting member 20. Accordingly, the first pressure sensor in this embodiment has relatively poor detection accuracy for the distance between the first mounting member 10 and the second mounting member 20, while the displacement sensor 60 in the aforementioned embodiment can accurately detect slight changes in the distance between the first mounting member 10 and the second mounting member 20. In other words, the aforementioned embodiment of the displacement sensor 60 is more accurate and sensitive. In actual implementation, the aforementioned embodiment of the displacement sensor 60 can be implemented preferentially.
[0063] In summary, the flexible abutment mechanism of the above embodiment of the utility model is provided with an elastic support assembly 30 between the first mounting member 10 and the second mounting member 20.
