In the present application, the illustrative description of the above terms does not necessarily refer to the same embodiment or implementation. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0026] As Figure 1As shown, the turnover machine is in operation, the turnover workbench 16 is fixed by two vertically arranged semi-circular bases (driven by a motor, generally 90 degrees), the lifting member 2 is arranged on the turnover workbench 16, specifically, the lifting saddle 202 and the lifting rack 201 are arranged on the two vertically arranged semi-circular bases, the cylindrical part or the shaft part is placed on the turnover workbench 16 along the Y-axis direction, the central axis of the cylindrical part or the shaft part is the Y-axis direction, the adjusting member 1 such as the adjusting saddle 102 and the adjusting beam 101 is used for the turnover of small-sized cylindrical joints and the like, because the small-sized cylindrical joint has small size, the cylindrical joint needs to be raised by the adjusting saddle 102, otherwise the lifting appliance cannot enter and exit; when the cylindrical joint is turned to the vertical state (the central axis is the Z-axis direction), if the adjusting beam 101 is not arranged, the vertical gripper cannot grab the bottom of the cylindrical joint, the adjusting beam 101 is arranged to raise the cylindrical joint, the purpose is to make the lifting appliance enter and lift the vertical cylindrical joint, therefore, the adjusting saddle 102 is arranged on the lifting saddle 202, and the adjusting beam 101 is arranged on the lifting rack 201, so that the normal turnover of the small-sized shaft part or the cylindrical part can be realized (for the turnover of large parts, the adjusting beam 101 and the adjusting saddle 102 are generally not needed to be arranged, they are wider than the lifting rack 201, the adjusting beam 101 and the adjusting saddle 102 can be removed, and the lifting appliance can directly hook the large part), in summary, in the use process, the adjusting member such as the adjusting saddle 102 needs to be frequently replaced due to wear and tear and disassembly, and the present application is to solve the problem that the adjusting member such as the adjusting saddle 102 cannot be quickly replaced, which affects the production efficiency.

[0027] In order to solve the above technical problems, referring to Figure 1 As shown, the turnover device replacement structure is used for detachable mounting of the adjusting member 1 on the lifting member 2, the lifting member 2 is arranged on the turnover workbench, the turnover device replacement structure comprises a pin shaft 3 and a first sleeve 4, the pin shaft 3 is fixed on the adjusting member 1, the pin shaft 3 is internally provided with a guide sleeve 8 which can slide and stretch along the radial direction of the pin shaft 3, one end of the guide sleeve 8 is elastically connected with the pin shaft 3, and the other end is provided with a first blocking part 11, the first blocking part 11 is exposed from the pin shaft 3, the inner wall of the first sleeve 4 is provided with a fixed block 5, the fixed block 5 is provided with a second blocking part 10, the second blocking part 10 is used for forming clamping with the first blocking part 11 after the pin shaft 3 is inserted into the first sleeve 4, the lifting member 2 is fixedly provided with a second sleeve 14, the first sleeve 4 is detachably arranged on the second sleeve 14, and the second sleeve 14 is sleeved on the periphery of the first sleeve 4 and the outer wall of the first sleeve 4 is attached to the inner wall of the second sleeve 14.

[0028] It should be noted that the adjusting component, as a part that is in direct contact with the part to be flipped, may need to be replaced in time due to the wear and tear caused by raising the part and during the flipping process. For example, when the lifting component 2 is the lifting platform 201, the adjusting component 1 can be the adjusting beam 101. The top of the adjusting component 1 is used to directly contact the part to be flipped.

[0029] In this embodiment, when the adjusting member 1 is installed on the lifting member 2, since the pin 3 is fixed on the adjusting member 1 and the first sleeve 4 is fixed on the lifting member 2, the pin 3 can be directly inserted along the first sleeve 4. Through the snap-fit ​​cooperation of the second blocking part 10 and the first blocking part 11, the adjusting member 1 is installed on the lifting member 2. Specifically, since one end of the guide sleeve 8 is elastically connected to the pin 3 and the guide sleeve 8 is radially slidably disposed on the pin 3, during the process of the pin 3 being directly inserted along the first sleeve 4, the guide sleeve 8 can drive the first blocking part 11 to slide back and enter the snap-fit ​​position corresponding to the second blocking part 10 on the fixing block 5. Subsequently, the guide sleeve 8 is reset, and the second blocking part 10 snaps into the first blocking part 11, thereby completing the installation of the adjusting member 1 on the lifting member 2. When disassembling the lifting member 2, it is only necessary to pull out the pin 3 in the reverse direction so that the first blocking part 11 is engaged. Once part 11 is disengaged from the position of the second blocking part 10, the adjustment part 1 can be disassembled from the lifting part 2. The insertion and extraction processes respectively complete the locking and unlocking of the locking and unlocking, which can ensure the quick replacement of the adjustment part 1 on the lifting part 2. Furthermore, the second sleeve 14 is sleeved on the periphery of the first sleeve 4 and the outer wall of the first sleeve 4 is in contact with the inner wall of the second sleeve 14. Thus, the second sleeve 14 forms a stable fixation on the first sleeve 4, thereby ensuring the stable insertion and extraction of the pin 3 from the first sleeve 4, ensuring the effective completion of the replacement. As the adjustment part 1 is replaced, if the first sleeve 4 is damaged and needs to be replaced, the first sleeve 4 can also be replaced by detachably being set on the second sleeve 14, thereby ensuring the quick, smooth and effective completion of the replacement. Overall, it reduces the labor intensity of workers and improves production efficiency.

[0030] like Figure 1 As shown, in an optional embodiment of the present invention, the adjusting component 1 is an adjusting saddle 102, the lifting component 2 is a lifting saddle 202, and / or the lifting component 2 is a lifting platform 201, and the adjusting component 1 is an adjusting crossbeam 101.

[0031] Specifically, for cylindrical or shaft-shaped parts, in order to achieve the flipping of the parts by the equipment, it is necessary to install an adjusting saddle 102 on the lifting saddle 202 and an adjusting beam 101 on the lifting platform 201 to achieve normal flipping of the shaft-shaped or cylindrical parts. The adjusting saddle 102 and the adjusting beam 101 can both be quickly installed using the method described in this utility model. The adjusting saddle 102 can be quickly installed on the lifting saddle 202, and the adjusting beam 101 can be quickly installed on the lifting saddle 202. In the flipping equipment, different actual sizes can be customized according to actual needs.

[0032] As an optional embodiment of this utility model, the pin 3 is provided with a through groove along the radial direction, one end of the through groove is provided with a pressure cap assembly, the guide sleeve 8 is slidably installed in the through groove and one end of the guide sleeve 8 is connected to the pressure cap assembly through a compression spring 7, and the other end extends out through the other end of the through groove. The pin 3 is also provided with a stop assembly for limiting the guide sleeve 8.

[0033] Specifically, the guide sleeve 8 is slidably mounted on the through groove. The pressure cap assembly acts as an overall block for the compression spring 7 and the guide sleeve 8, and bears the force brought about by the engagement of the second blocking part 10 and the first blocking part 11. The stop assembly acts as a sliding limit for the guide sleeve 8. The pressure cap assembly can be, for example, a cover-shaped structure, and its size is larger than that of the compression spring 7 to ensure that it can withstand a sufficiently large force. The stop assembly can be a limiting seat, which is directly set at the sliding end position of the guide sleeve 8 (near the fixed block 5). The pressure cap assembly and the stop assembly are generally set correspondingly. The above ensures the smooth completion of the engagement between the second blocking part 10 and the first blocking part 11, and the guide sleeve 8 can move along the direction of the through groove.

[0034] As an optional embodiment of this utility model, the pressure cap assembly includes a pressure cap 6 and a first bolt group. The pressure cap 6 is embedded in the through groove of the pin 3, and the inner end face of the pressure cap 6 abuts against the compression spring 7. The outer end face of the pressure cap 6 is flush with the outer side face of the pin 3. The first bolt group is used to connect the pressure cap 6 and the pin 3.

[0035] Specifically, the pressure cap 6 is inserted into the through groove along the extension direction of the through groove and embedded in the pin 3, so that the inner end face of the pressure cap 6 abuts against the compression spring 7 and the outer end face is flush with the outer side of the pin 3, so that the pin 3 is not affected when it extends out or is inserted into the first sleeve 4. The pressure cap 6 is installed at the end of the guide sleeve 8 away from the fixing block 5. The pin 3 can be provided with multiple countersunk holes at one end of the through groove. The first bolt group can be set as multiple bolts corresponding to the multiple countersunk holes, so that it can stably bear the reaction force of the compression spring 7.

[0036] likeFigure 3 As shown, in an optional embodiment of the present invention, the stop assembly includes a stop block 9, which is embedded in the pin 3, and the other end of the guide sleeve 8 is provided with a sliding groove 15, and the stop block 9 is slidably connected to the sliding groove 15.

[0037] Specifically, the stop block 9 is inserted from the side of the pin 3 and embedded in the side of the pin 3. It is best to install it without protrusion, that is, the outer surface of the stop block 9 is flush with the outer surface of the pin 3, and the bottom end of the stop block 9 extends into the slide groove 15. This allows the guide sleeve 8 to slide a certain distance along the through groove and not to fall off the pin 3. The stop block 9 can be installed on the pin 3 with bolts, thus realizing detachability and replaceability. Multiple stop blocks 9 can be provided. When the guide sleeve 8 is slidably installed in the through groove, its tail can be provided with a stepped part. The through groove is set to match the shape of the stepped part and can play a certain role in limiting the sliding of the guide sleeve 8. The guide sleeve 8 can be removed from one end of the pressure cap assembly.

[0038] The guide sleeve 8 can be configured as a cylindrical structure with one end closed and the other end open. Thus, one end of the compression spring 7 extends into the guide sleeve 8 through the opening, and the other end abuts against the pressure cap 6, so as to ensure the stability of the extension and retraction direction of the compression spring 7 and reduce the space occupied by the compression spring 7.

[0039] like Figure 2 , Figure 3 and Figure 4 As shown, in an optional embodiment of the present invention, the first blocking part 11 is provided with an adjacent first guide surface and a first inclined surface, and the second blocking part 10 is provided with an adjacent second guide surface and a second inclined surface. Along the insertion direction of the pin 3, the second inclined surface is provided at the bottom of the second guide surface. When the second blocking part 10 engages with the first blocking part 11, the first inclined surface and the second inclined surface are in contact.

[0040] Specifically, the first guide surface and the first inclined surface are formed Figure 4 The protrusion shown on the left side, the second guide surface and the second inclined surface are also formed. Figure 4The protrusion shown on the right side, when in the installation state, forms a vertical blockage between the second blocking part 10 and the first blocking part 11. During the process of installing the adjusting part 1 and the pin 3 onto the adjusting part 1, the first guide surface of the first blocking part 11 on the guide sleeve 8 contacts the second guide surface of the second blocking part 10 on the fixing block 5. The compression spring 7 is compressed and retracts, and the adjusting part 1 is further inserted until the first inclined surface and the second inclined surface are in contact, thus completing the quick installation. Due to the interaction between the inclined surfaces, the adjusting part 1 and the pin 3 will not fall off the lifting part 2 and the first sleeve 4. When you want to remove the adjusting part 1 and the pin 3 from the lifting part 2 and the first sleeve 4, you only need to pull the adjusting part 1 out of the lifting part 2 using a lifting device. The lifting force of the lifting device must be greater than the frictional force generated between the first inclined surface of the first blocking part 11 and the second inclined surface of the fixing block 5 formed by the pressure of the compression spring 7.

[0041] like Figure 2 and Figure 3 As shown, in an optional embodiment of the present invention, the outer diameter of the pin 3 is reduced at the snap-fit ​​position between the second blocking part 10 and the first blocking part 11.

[0042] Specifically, at the snap-fit ​​position, that is, at the position where the guide sleeve 8 and the fixing block 5 are installed, since both the guide sleeve 8 and the fixing block 5 need to be protruding, and the pin 3 and the first sleeve 4 are fitted together internally and externally, the outer diameter of the pin 3 at the position of the guide sleeve 8 and the fixing block 5 is appropriately reduced to leave clearance space, which facilitates the snap-fit ​​between the first blocking part 11 and the second blocking part 10. In addition, it also facilitates the disassembly and assembly of other components such as the pressure cap assembly and the clearance assembly. It should be noted that the snap-fit ​​position is preferably set at the bottom of the pin 3, so that the installation of the adjusting part 1 on the lifting part 2 is more stable.

[0043] like Figure 2 and Figure 5 As shown, in an optional embodiment of this utility model, the first sleeve 4 extends into the second sleeve 14 from the top end of the second sleeve 14 and is coaxially arranged with the second sleeve 14. The top end of the first sleeve 4 is provided with a first mounting seat 12, and the top end of the second sleeve 14 is provided with a second mounting seat 13. The bottom end of the second sleeve 14 extends into the lifting member 2 and is fixedly connected to the lifting member 2. The second mounting seat 13 is fixedly connected to the top surface of the lifting member 2. The second mounting seat 13 is provided with a groove for fitting and engaging with the first mounting seat 12. The first mounting seat 12 and the second mounting seat 13 are connected by a second bolt group.

[0044] Specifically, the first sleeve 4 and the second sleeve 14 are arranged coaxially. To allow the second sleeve 14 to fit around the first sleeve 4, the first sleeve 4 extends from the top of the second sleeve 14, with its bottom end inside the second sleeve 14. The first sleeve 4 is detachably fixed to the second sleeve 14 via a first mounting base 12. The first mounting base 12 is placed within a groove on the second mounting base 13, the shape of which matches the shape of the first mounting base 12. The surface of the first mounting base 12 is flush with the surface of the second mounting base 13, and... The first mounting base 12 and the second mounting base 13 are fixed by the second bolt group. The first mounting base 12 is provided with countersunk holes, so that the top of the screws of the second bolt group is not higher than the surface of the first mounting base 12 after installation. This will not affect the fit between the second mounting base 13 and the bottom of the adjusting member 1. The first sleeve 4 is firmly fixed to the lifting member 2 by the second sleeve 14, ensuring that the adjusting member 1 can be firmly installed on the lifting member 2, realizing the flipping of the parts, and the first sleeve 4 will not be easily damaged during disassembly. The first sleeve 4 can also be disassembled for easy replacement.

[0045] like Figure 2 As shown, in an optional embodiment of the present invention, the top end of the pin 3 extends into the adjusting member 1 and is fixedly connected to the adjusting member 1. The bottom end of the adjusting member 1 is a multi-layer plate structure. The bottom end of the pin 3 extends out of the multi-layer plate structure and is used to extend into the first sleeve 4. The multi-layer plate structure is used to fit against the surface of the second mounting base 13.

[0046] Specifically, the adjusting component 1 itself is also configured as a frame structure, and a multi-layer plate structure is provided at the bottom of the frame structure. It is formed by stacking and reinforcing multiple layers of plates. The top end of the pin 3 extends into the adjusting component 1 and is fixedly connected to the adjusting component 1. The crossbeam of the adjusting component 1 can be used to reinforce the pin 3. The bottom end of the pin 3 extends out of the multi-layer plate structure. In this way, the pin 3 is reinforced on the one hand, and the contact between it and the surface of the second mounting seat 13 is achieved on the other hand. Since both are planar structures, the contact surfaces of the two can achieve seamless contact, which makes the adjusting component 1 more stable when it is installed on the lifting component 2 through the cooperation of the pin 3 and the first sleeve 4.

[0047] like Figure 2 As shown, in an optional embodiment of this utility model, the lifting component 2 is a frame structure, and the bottom end of the second sleeve 14 is fixedly connected to the frame structure.

[0048] Specifically, the lifting component 2 is also configured as a frame structure with horizontal and vertical beams connected, and this frame structure is also set in its inner cavity. Thus, the frame structure can fix the bottom end of the second sleeve 14 that extends into it, thereby ensuring the stability of the second sleeve 14, and thus ensuring the stable placement of the first sleeve 4 on the second sleeve 14.

[0049] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
