[0002] The pin mounting seat is a relatively important structural part of the upper part of the scissor-type aerial work platform. Its main function is to install the mounting wheels used in the sliding process of the fixed extension platform. The pin mounting seat has a great influence on the smoothness of the normal extension and retraction of the extension platform at the upper part of the scissor-type aerial work platform. The pin mounting seat is mainly composed of two parts, the mounting seat plate and the mounting pin, which are welded together. There is a high verticality requirement between the two parts.

[0003] At present, the manufacturing process of the pin shaft mounting seat mainly includes two processes: riveting and welding positioning and welding.

During the welding process, the weld between the mounting pin shaft and the mounting seat plate is manually welded, and the weld quality and stability are poor.

[0004] Therefore, it is necessary to design a new pin shaft mounting seat manufacturing device to overcome or alleviate the above technical problems. Utility Model Content

It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0061] It should be noted that, in the description of this application, unless otherwise specified, the indicated orientation or positional relationship is only for the convenience of describing this application and simplifying the description, and does 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 of this application. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0062] like Fig.11 As shown, the embodiment of the present application provides a welding gun position adjustment device 3, which includes a welding gun support system and a welding gun drive mechanism mounting seat 33. The welding gun support system is used to install a welding gun 31, and a welding gun drive mechanism 32 is installed on the welding gun drive mechanism mounting seat 33. The welding gun drive mechanism 32 is connected to the welding gun support system, and the welding gun support system is slidably installed on the welding gun drive mechanism mounting seat 33, so that the welding gun drive mechanism 32 can drive the welding gun support system to move along a set direction on the welding gun drive mechanism mounting seat 33. Among them, the welding gun drive mechanism 32 can be a driving device such as a telescopic cylinder, a hydraulic cylinder or an electric cylinder.

[0063] In some embodiments, the welding gun support system is mounted on the welding gun drive mechanism mounting base 33 by a sliding device.

[0064] As a specific structural form of the sliding device, Fig.11 , Fig.14 and Fig.15 As shown, the sliding device includes a slider 341 and a linear guide 342. The slider 341 is arranged at the bottom of the support seat 36 of the welding gun support system. Two linear guides 342 are arranged in parallel on the welding gun drive mechanism mounting seat 33. The slider 341 and the linear guide 342 cooperate with each other to realize the movement of the welding gun support system on the welding gun drive mechanism mounting seat 33 along the set direction. It can be understood that the two linear guides 342 can also be arranged at the bottom of the support seat 36 of the welding gun support system. Accordingly, the slider 341 is arranged on the welding gun drive mechanism mounting seat 33. The slider 341 and the linear guide 342 cooperate with each other, which is a precisely matched sliding device. The sliding device has high positioning accuracy, which can effectively ensure the stability of the position of the support seat 36 in the left and right and up and down directions during the movement process, and realize the movement of the welding gun support system on the welding gun drive mechanism mounting seat 33 along the set direction.

[0065] It should be noted that the linear guide structure formed by the slider 341 and the linear guide 342 is a conventional technology for achieving linear sliding. The linear guide structure generally has a positioning and locking function, which can push the bracket seat 36 to a preset position and lock it in the preset position. It is well known to those skilled in the art and will not be described in detail.

[0066] In some embodiments, both ends of each linear guide rail 342 are respectively covered with a dust cover 35. By retracting the dust cover 35, most of the linear guide rail 342 can be covered to play a dust-proof role.

[0067] In some embodiments, Fig.11 As shown, the welding gun bracket system includes a bracket seat 36 and a bracket, the bracket is used to install the welding gun 31, and the bracket is installed on the bracket seat 36. Among them, the bracket includes a first connecting rod 371 and a second connecting rod 372, the second connecting rod 372 is rotatably installed on the first connecting rod 371, the second connecting rod 372 is used to install the welding gun 31, and the first connecting rod 371 is installed on the bracket seat 36.

[0068] In some embodiments, the welding gun support system is provided with an angle adjustment device, which is used to adjust the angle of the welding gun 31 so that the welding gun 31 can be aligned with the position to be welded between the pin 42 and the mounting plate 41. The welding gun 31 can be a CO2 welding gun or other suitable welding gun.

[0069] In some embodiments, Fig.12 As shown, the bracket also includes a clamp 373, which includes two clamping members arranged opposite to each other. V-shaped grooves are provided on the opposite surfaces of the two clamping members to form a diamond clamp, so that the welding gun 31 is clamped between the two clamping members. The angle adjustment device includes a first adjustment section 374, a second adjustment section 375 and a third adjustment section 376. The first adjustment section 374, the second adjustment section 375 and the third adjustment section 376 can all be Fig.12The clamp structure shown is composed of two clamping parts. Correspondingly, a clamp mounting rod connected to the third adjustment section 376 is provided on the side of the end of the clamp 373. The clamp mounting rod, the first connecting rod 371 and the second connecting rod 372 can all be round rods. The first adjustment section 374 is clamped on the first connecting rod 371, and the first connecting rod 371 can rotate relative to the first adjustment section 374. The second adjustment section 375 is clamped on the second connecting rod 372, and the second connecting rod 372 can rotate relative to the second adjustment section 375. The first adjustment section 374 and the second adjustment section 375 are fixedly connected, so that the clamp 373 can rotate relative to the second connecting rod 372. The third adjustment section 376 is installed at the end of the second connecting rod 372. The third adjustment section 376 is clamped on the clamp mounting rod so that the clamp mounting rod can rotate relative to the third adjustment section 376, which is used to realize that the clamp 373 can rotate relative to the second connecting rod 372. Therefore, by setting the first adjustment section 374 , the second adjustment section 375 and the third adjustment section 376 , the posture angle and position of the welding gun 31 can be adjusted.

[0070] In some embodiments, Fig.11 As shown, a limiting device 38 is also provided, and the limiting device 38 is arranged relative to the welding gun driving mechanism 32. When the welding gun driving mechanism 32 drives the bracket seat 36 to move to the position of the limiting device 38, the end of the bracket seat 36 abuts against the limiting device 38 to ensure the stability of the position of the welding gun bracket system.

[0071] In some embodiments, Fig.13 As shown, a limiting block is provided at one end of the bracket seat 36 facing the limiting device 38 , and the limiting block can be snap-connected with the limiting device 38 . Specifically, the limit block includes a concave limit block 391 and a convex limit block 392 connected in sequence, the cross-section of the convex limit block 392 is an inverted Z-type or staircase-type, the convex limit block 392 is installed on the end face of the bracket seat 36 away from the welding gun drive mechanism 32, the cross-section of the concave limit block 391 is an I-shape, the cross-section of the limit device 38 is an inverted Z-type or staircase-type, one side groove position of the concave limit block 391 is engaged with the convex limit block 392, and the other side groove position of the concave limit block 391 faces the limit device 38. When the welding gun drive mechanism 32 pushes the bracket seat 36 to the limit device 38, the other side groove position of the concave limit block 391 is engaged with the limit device 38, which can effectively ensure the stability of the front and back and up and down directions of the bracket seat 36 during the movement, thereby ensuring the stability of the moving position of the welding gun bracket system.

[0072] Moreover, the above-mentioned limiting device 38 and limiting block are set at one end of the bracket seat 36, and the linear guide rail 342 and the slider 341 are used in combination. These two methods can better ensure the stability of the position of the welding gun 31.

[0073] In order to better understand the technical solution of the welding gun position adjustment device of the present application, the welding gun position adjustment device of the present application can be used in combination with other devices to form a Figure 3 The pin shaft mounting seat manufacturing device shown.

[0075] like Figure 1 and Figure 2 As shown, there is a high verticality requirement between the two workpieces such as the mounting plate 41 and the pin 42. The first positioning fixture 1 and the second positioning fixture 2 of the present application are used to replace the manual hand-held force to ensure the verticality of the two workpieces such as the mounting plate 41 and the pin 42. The riveting and welding positioning method can greatly improve the verticality accuracy and stability of the mounting plate 41 and the pin 42. Moreover, the welding gun position adjustment device 3 is used to replace manual welding, which can greatly improve the welding quality of the annular weld between the mounting plate 41 and the pin 42.

[0076] In some embodiments, Figure 1 , Figure 6 and Figure 7 As shown, a rotating mechanism 5 can be provided, and the first positioning seat 11 can be installed on the rotating mechanism 5, so that the rotating mechanism 5 can drive the first positioning seat 11 to rotate, and then drive the mounting seat plate 41 and the pin shaft 42 to rotate as a whole, and cooperate with the welding gun position adjustment device 3 to realize automatic welding of the annular weld, thereby reducing the problem of high weld quality defects caused by manual welding of the annular weld here, reducing the time for rework and rework, and reducing production costs.

[0077] As a specific embodiment of the rotating mechanism 5, Figure 6 and Figure 7 As shown, the rotating mechanism 5 includes a second driving mechanism 51 and a fastening device 52, wherein the fastening device 52 is used to fasten the first positioning seat 11, and the fastening device 52 is connected to the second driving mechanism 51. The second driving mechanism 51 may be a servo motor, and the fastening device 52 may be a three-jaw chuck device, such as Figure 4 and Figure 5As shown, a clamping member 12 is provided on the first positioning seat 11, and the three-jaw chuck device can clamp the clamping member 12, such as the clamping member 12 can be a cylinder provided on the back of the first positioning seat 11, to ensure the stability of the first positioning fixture 1. A servo motor with good low-speed stability and high control accuracy is selected and connected to the three-jaw chuck device, and the servo motor is rotated to ensure that no eccentricity occurs during the rotation process, so as to ensure the stability of the welding position of the annular weld.

[0078] In some embodiments, Figure 4 and Figure 5 As shown, a positioning groove 13 is provided on the side of the first positioning seat 11 opposite to the clamping member 12, and the inner contour of the positioning groove 13 can be processed by profiling with reference to the edge of the outer contour of the mounting seat plate 41, so that the inner contour of the positioning groove 13 can be consistent with the outer contour of the mounting seat plate 41, so that the mounting seat plate 41 can be better positioned in the positioning groove 13. Furthermore, the depth of the positioning groove 13 is the same as the thickness of the mounting seat plate 41.

[0079] Furthermore, if Figure 4 As shown, a plurality of adsorbents 14 can be arranged in the positioning groove 13, and the adsorbents 14 are used to adsorb the mounting plate 41 to prevent the mounting plate 41 from falling off during the assembly process, thereby ensuring the rapid assembly and stability of the mounting plate 41. The adsorbents 14 can be strong magnets, and the mounting plate 41 is made of iron, so that the mounting plate 41 can be adsorbed well; or other structural forms that can achieve adsorption of the mounting plate 41 can also be used, and these should all fall within the protection scope of this application.

[0080] In some embodiments, Figure 8 and Fig. 9 As shown, the second positioning seat includes a positioning component 22 and a positioning seat plate 23. The positioning component 22 is installed on the positioning seat plate 23, and a positioning hole for inserting the pin 42 is provided on the positioning component 22. The inner diameter of the positioning hole is slightly larger than the outer diameter of the pin 42, and the hole depth of the positioning hole is greater than one-third of the length of the pin 42 and less than the length of the pin 42, such as the hole depth of the positioning hole is 25 mm. During the assembly process, the pin 42 only needs to be directly inserted into the positioning hole of the positioning component 22 to achieve the positioning of the pin 42.

[0081] Furthermore, if Fig.16As shown, a locating bearing 27 can be arranged in the locating hole, and the diameter of the portion of the pin shaft 42 inserted into the locating bearing 27 can be smaller than the diameter of other portions, so that the pin shaft 42 forms a stepped shaft structure as a whole. In order to install the locating bearing 27 and prevent the locating bearing 27 from slipping out of the locating hole, the locating hole can form a stepped hole structure at a position corresponding to the locating bearing 27, so that the locating bearing 27 can abut against the side of the stepped hole structure. The arrangement of the locating bearing 27, on the one hand, assists in the positioning of the pin shaft 42, and on the other hand, can facilitate the smoother rotation of the pin shaft 42, facilitate the welding of the annular weld between the installation seat plate 41 and the pin shaft 42, and, further, can reduce the wear between the outer peripheral wall of the pin shaft 42 and the hole wall of the locating hole, thereby further improving the quality of the finished product.

[0082] Furthermore, if Fig.16 As shown, a limited retaining ring 28 can be provided on the end surface of the positioning bearing 27 facing the positioning seat plate 23, and an elastic element 29 is provided between the limited retaining ring 28 and the bottom of the positioning hole. Under the action of the elastic element 29, the limited retaining ring 28 is abutted against the positioning bearing 27, and then, on the one hand, the pin shaft 42 can be abutted against the mounting seat plate 41 to ensure the verticality between the pin shaft 42 and the mounting seat plate 41, and the quality of the finished product; on the other hand, in the process of positioning the pin shaft 42 on the mounting seat plate 41, the impact force of the pin shaft 42 on the mounting seat plate 41 can be buffered to avoid the collision between the two causing the structure of the connection to be deformed or the positioning position to be offset. Among them, the elastic element 29 can be an elastic element such as a spring, rubber, or silicone.

[0083] In some embodiments, the positioning seat plate 23 is mounted on the first driving mechanism 21 through the connecting plate 24, so that the first driving mechanism 21 can drive the positioning seat plate 23 to move forward, and finally assemble the two workpieces such as the pin 42 and the mounting seat plate 41 into place. The first driving mechanism 21 can be a driving device such as a telescopic cylinder, a hydraulic cylinder or an electric cylinder.

[0084] In some embodiments, an adjustment positioning hole is provided on the connection plate 24, and a connector is used to pass through the positioning seat plate 23 and the adjustment positioning hole on the connection plate 24 to install the positioning seat plate 23 on the connection plate 24. For example, a bolt can be used as a connector, and the bolt is set on the positioning seat plate 23 or passes through the positioning seat plate 23, and then the bolt is passed through the adjustment positioning hole, and the adjustment positioning hole can be a through hole set on the connection plate 24, and the bolt and the adjustment positioning hole are clearance-matched, allowing a certain positioning adjustment space between the positioning seat plate 23 and the connection plate 24, and then a position adjustment device is set on the connection plate 24 to adjust the positioning position of the positioning seat plate 23.

[0085] As a specific structural form of the positioning position, the position adjustment device includes a first adjustment device and a second adjustment device, and the first adjustment device and the second adjustment device are respectively in contact with two adjacent side surfaces of the positioning seat plate 23. Figure 8 and Fig. 9 As shown, the first adjustment device includes a first adjustment block 251 and a first adjustment gasket 252. The first adjustment block 251 is in contact with one side of the positioning seat plate 23. The first adjustment gasket 252 is added or removed between the side of the positioning seat plate 23 and the first adjustment block 251 to fine-tune the positioning position of the positioning seat plate 23 in the up-down direction. Similarly, the second adjustment device includes a second adjustment block 253 and a second adjustment gasket 254. The second adjustment block 253 is in contact with the other side of the positioning seat plate 23. The second adjustment gasket 254 is added or removed between the side of the positioning seat plate 23 and the second adjustment block 253 to fine-tune the positioning position of the positioning seat plate 23 in the left-right direction. Fig.10 As shown, the first adjusting device and the second adjusting device are used to fine-tune the positioning position of the positioning seat plate 23, so that the pin 42 is aligned with the positioning position on the mounting seat plate 41, and the two workpieces such as the pin 42 and the mounting seat plate 41 are assembled in place. Among them, the first adjusting gasket 252 and the second adjusting gasket 254 can be adjusting gaskets with a certain thickness, such as 1mm, 2mm, 3mm or other thickness of metal sheets. Moreover, the position of the pin 42 in two directions can also be adjusted according to the actual welding effect. Alternatively, the first adjusting device and the second adjusting device can also adopt other structural forms, such as an adjusting bolt is provided on the adjusting block, the end of the bolt abuts against the side of the positioning seat plate 23, and the position of the pin 42 in two directions is adjusted by screwing in or out of the bolt. In the production process, the position of the pin 42 can be adjusted by adjusting the first adjusting gasket 252 and the second adjusting gasket 254 to ensure the verticality of the pin 42 and the mounting seat plate 41.
