The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.
[0021] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.
[0022] The following is for reference. Figures 1 to 13 The welding system of this application is described in detail.
[0023] refer to Figure 1 and Figure 7 According to an embodiment of the present invention, a welding system includes a loading module 100, a shaping module 200, an assembly module 300, and a welding module 400; the loading module 100 is used to load a cylindrical component; the shaping module 200 is used to shape a spring sheet so that the spring sheet is bent into an arc shape that fits the inner wall of the cylindrical component; the assembly module 300 is disposed on one side of the shaping module 200 and is used to assemble the bent spring sheet in the shaping module 200 to the inner wall of the cylindrical component; the welding module 400 is disposed on one side of the loading module 100 and is used to weld the spring sheet and the inner wall of the cylindrical component.
[0024] Understandably, during the operation of the welding module 400 of this application, the cylindrical component can be loaded onto the loading module 100, the shaping module 200 can automatically shape the spring piece to bend it into an arc that fits the inner wall of the cylindrical component, and then the assembly module 300 can assemble the bent spring piece onto the inner wall of the cylindrical component. Next, the welding module 400 can complete the welding between the spring piece and the inner wall of the cylindrical component. Therefore, the welding system of this application can automatically complete the welding of the spring piece to the inner wall of the cylindrical component, saving time and effort.
[0025] In some embodiments of the present invention, the shaping module 200 includes a first mounting base 210 and a shaping component 220. The first mounting base 210 is provided with a shaping surface adapted to the inner wall of the cylindrical component. The shaping component 220 includes a first driving structure 221 and a plurality of shaping elements. The plurality of shaping elements are arranged around the shaping surface to define a shaping area for accommodating the spring sheet. The first driving structure 221 is connected to each shaping element and is used to drive the shaping elements to move closer to or away from the shaping surface.
[0026] For example, such as Figure 2 and Figure 3 As shown, the shaping module 200 includes a first mounting base 210 and a shaping component 220. The first mounting base 210 is provided with a vertically extending shaping column 211. The circumferential surface of the shaping column 211 constitutes a shaping surface, and the shape of the shaping surface is adapted to the inner sidewall of the cylindrical component. The shaping component 220 includes a first driving structure 221 and a plurality of shaping parts. The plurality of shaping parts are circumferentially distributed around the shaping column 211, and a shaping area is formed between the shaping parts and the shaping surface. The first driving structure 221 is provided on the first mounting base 210 and is connected to each shaping part respectively.
[0027] Understandably, when the shaping module 200 is working, the spring sheet to be shaped can be placed in the shaping area. Then, under the drive of the first driving structure 221, each shaping component can approach the shaping surface. Thus, under the pressure of the shaping component, the spring sheet can deform to fit the shaping surface, thereby completing the shaping of the spring sheet.
[0028] In a further embodiment of the present invention, the plurality of shaping components include a first shaping component 222 and two second shaping components 223. The first shaping component 222 is located between the two second shaping components 223. The first shaping component 222 is used to shape the middle part of the spring sheet, and the two second shaping components 223 are respectively used to shape the opposite ends of the spring sheet. The first driving structure 221 includes a first driver 221a and a transmission component 221b. The transmission component 221b is connected to the first shaping component 221a via an elastic connector 221c. The forming member 222 is connected, and the transmission member 221b is provided with two abutting inclined surfaces 221d. The first driver 221a is connected to the transmission member 221b. Under the drive of the first driver 221a, the transmission member 221b can push the first shaping member 222 to shape the middle part of the spring piece through the elastic connecting member 221c. As the elastic connecting member 221c is compressed, the two abutting inclined surfaces 221d can push the two second shaping members 223 to shape the opposite ends of the spring piece respectively.
[0029] For example, such as Figure 2 and Figure 3 As shown, the first shaping component 222 is slidably disposed on the first mounting base 210 in the left-right direction. Two second shaping components 223 are located on the front and rear sides of the first shaping component 222, and the second shaping components 223 are slidably disposed on the first mounting base 210 in the front-back direction. The first driving structure 221 includes a first driver 221a and a transmission component 221b. The transmission component 221b is disposed on the right side of the first shaping component 222, and the transmission component 221b is slidably disposed on the first mounting base 210 in the left-right direction. The left end of the transmission component 221b is connected to the right end of the first shaping component 222 through an elastic connector 221c. The transmission component 221b is provided with two abutting inclined surfaces 221d, which are distributed in the front-back direction. Both second shaping components 223 are provided with vertically extending abutting posts. The first driver 221a is disposed on the right side of the transmission component 221b and is connected to the right end of the transmission component 221b.
[0030] Furthermore, when the shaping module 200 of this application is working, the spring can be placed between the first shaping member 222 and the shaping post 211. Under the drive of the first driver 221a, the transmission member 221b moves to the left. During this process, the transmission member 221b drives the first shaping member 222 to move to the left synchronously through the elastic connector 221c, so that the first shaping member 222 cooperates with the shaping post 211 to clamp the middle part of the spring and complete the shaping of the middle part of the spring. Then, under the continued drive of the first driver 221a, the elastic connector 221c is compressed, and the transmission member 221b continues to move to the left, so that the two abutting inclined surfaces 221d can abut the two abutting posts respectively, so that the two second shaping members 223 can approach each other to push the front and rear ends of the spring to the shaping surface respectively, thereby completing the shaping of the entire spring.
[0031] It is understood that by setting two abutting inclined surfaces 221d on the transmission component 221b, a single transmission component 221b can simultaneously drive the movement of the first shaping component 222 and the two second shaping components 223, thereby enabling a single first driver 221a to complete the driving of the first shaping component 222 and the two second shaping components 223, reducing the number of driving sources and lowering the manufacturing cost of the shaping module 200 of this application.
[0032] It is understandable that by setting the elastic connector 221c and placing the first shaping member 222 between the two second shaping members 223, under the drive of the first driver 221a, the first shaping member 222 can first push the middle part of the spring sheet to fit against the shaping surface, and then the two second shaping members 223 push the two ends of the spring sheet to fit against the shaping surface, thereby enabling the spring sheet to completely fit against the shaping surface after shaping, reducing the probability of gaps between the spring sheet and the shaping surface, and improving the shaping accuracy and shaping effect of the spring sheet.
[0033] It should be noted that after the first shaping component 222, the second shaping component 223, and the shaping surface have completed the shaping of the spring sheet, since the spring sheet is attached to the shaping surface, ordinary grippers cannot remove the spring sheet from the shaping area.
[0034] For the reasons mentioned above, in some embodiments of the present invention, the shaping module 200 further includes an ejection component 230, which includes a second driving structure 231 and a first ejector 232. The first ejector 232 is disposed in the shaping area, and the second driving structure 231 is connected to the first ejector 232. The second driving structure 231 can eject the spring sheet out of the shaping area through the first ejector 232.
[0035] For example, such as Figure 2 and Figure 3 As shown, the ejection assembly 230 includes a second drive structure 231 and a first ejector 232. The first ejector 232 is slidably disposed in the shaping area in the vertical direction. The output end of the second drive structure 231 is connected to the first ejector 232 and is used to drive the first ejector 232 to perform lifting and lowering movements.
[0036] Understandably, after the shaping component 220 completes the shaping of the spring piece, the first ejector 232 rises under the drive of the second drive structure 231, thereby ejecting the shaped spring piece upwards out of the shaping area so that the subsequent assembly module 300 can pick up the spring piece.
[0037] It should be noted that after the first shaping member 222 and the second shaping member 223 complete the shaping of the spring sheet on the shaping surface, the thickness of the spring sheet is small, and the width of the shaping area is small. If the size of the first ejector member 232 is set to be small, although the first ejector member 232 can be accommodated in the shaping area, the strength of the first ejector member 232 is low due to its small size, and the first ejector member 232 is prone to deformation during the ejection of the spring sheet.
[0038] For the reasons stated above, in some embodiments of the present invention, reference is made to... Figure 3 At least one of the shaping member and the shaping surface is provided with a relief groove 222a for accommodating the first ejector 232.
[0039] It is understandable that by providing a relief groove 222a on at least one of the shaping parts and the shaping surface, a portion of the structure of the first ejector 232 can be accommodated within the relief groove 222a. Under the premise that the first ejector 232 has sufficient strength, the first ejector 232 can successfully complete the ejection of the spring piece in the shaping area.
[0040] In some embodiments of the present invention, the assembly module 300 includes a drive component 310 and an assembly component 320. The drive component 310 is connected to the assembly component 320 and is used to drive the assembly component 320 to move between the shaping module 200 and the loading module 100. The assembly component 320 includes a second mounting base 321, a third drive structure 322 and a second ejector 323. The second mounting base 321 is provided with an annular cavity 321a for accommodating a spring piece. The second ejector 323 is at least partially slidably disposed within the annular cavity 321a. The third drive structure 322 is disposed on the second mounting base 321 and connected to the second ejector 323. The third drive structure 322 can drive the second ejector 323 to move axially along the annular cavity 321a to eject the spring piece out of the annular cavity 321a.
[0041] For example, such as Figure 4 and Figure 5 As shown, the assembly module 300 includes a drive assembly 310 and an assembly assembly 320. The assembly assembly 320 includes a second mounting base 321, a third drive structure 322, and a second ejector 323. The second mounting base 321 is provided with a vertically extending annular cavity 321a. The annular cavity 321a is adapted to the inner wall of the cylindrical component. The second ejector 323 is slidably disposed in the vertical direction and at least partially passes through the annular cavity 321a. The third drive structure 322 is disposed on the second mounting base 321 and connected to the second ejector 323.
[0042] Furthermore, when assembling the spring piece in the assembly module 300, under the drive of the drive component 310, the assembly component 320 can move above the shaping area and make the lower cavity of the annular cavity 321a face the shaping area. At this time, under the drive of the second drive structure 231, the first ejector 232 moves upward to push the shaped spring piece upward into the annular cavity 321a. Then, under the drive of the drive component 310, the assembly component 320 can move above the loading module 100 and make the lower cavity of the annular cavity 321a face the inner cavity of the cylindrical component. At this time, under the drive of the third drive structure 322, the second ejector 323 moves downward to push the spring piece in the annular cavity 321a into the inner cavity of the cylindrical component.
[0043] It should be noted that after the spring is shaped, the spring itself stores elastic potential energy. During the process of the spring being transferred from the shaping area to the inner cavity of the cylindrical component, the spring is elastically reset by the action of its own elastic potential energy, which makes it impossible for the spring to be successfully assembled into the inner cavity of the cylindrical component.
[0044] It is understandable that by setting the annular cavity 321a, the assembly module 300 can keep the spring piece in its shaped state under the limiting effect of the cavity wall of the annular cavity 321a during the transportation of the spring piece, thereby reducing the probability of the spring piece rebounding due to its own elasticity and ensuring that the spring piece can be smoothly assembled into the inner cavity of the cylindrical part.
[0045] In some embodiments of the present invention, reference is made to Figure 7 and Figure 8 The loading module 100 includes a fixture body 110 and multiple clamping components 120. The fixture body 110 has a mounting hole 110a and an annular bearing portion 111 around the mounting hole 110a. The bearing portion 111 is used to carry the spring piece. The fixture body 110 has an arc-shaped limiting portion 112 around the bearing portion 111. The limiting portion 112 and the bearing portion 111 define a positioning area 110b, which is used to position the cylindrical component. The clamping component 120 includes a clamping claw 121 and a fourth driving structure 122. The fourth driving structure 122 is connected to the clamping claw 121. Multiple clamping claws 121 are circumferentially distributed in the mounting hole 110a around the axis of the mounting hole 110a. Under the drive of each fourth driving structure 122, each clamping claw 121 can cooperate to push the spring piece to fit against the inner wall of the cylindrical component.
[0046] For example, such as Figures 7 to 11As shown, the welding fixture includes a fixture body 110 and five clamping components 120. The fixture body 110 has a vertically extending mounting hole 110a. The fixture body 110 has an annular support portion 111 around the mounting hole 110a. The upper end of the support portion 111 is used to support the spring piece. The fixture body 110 has an arc-shaped limiting portion 112 around the support portion 111. There are two limiting portions 112 in the left-right direction. The two limiting portions 112 and the support portion 111 together define an annular positioning area 110b. The positioning area 110b is used to accommodate the cylindrical part and position the cylindrical part. The clamping components 120 include clamping claws 121 and a fourth driving structure 122. All five clamping claws 121 are inserted into the mounting hole 110a and are circumferentially spaced around the vertical axis of the mounting hole 110a.
[0047] Understandably, when the loading module 100 of this application is working, the cylindrical part can be fitted into the positioning area 110b, and the assembly module 300 can place the spring piece on the bearing part 111. Under the drive of each fourth drive structure 122, each pressure claw 121 can move away from each other, so that each pressure claw 121 can cooperate to push the spring piece to fit against the inner side wall of the cylindrical part, so that the subsequent welding equipment can complete the welding between the spring piece and the cylindrical part. After the subsequent welding module 400 completes the welding between the spring piece and the cylindrical part, under the drive of each fourth drive structure 122, each pressure claw 121 can move closer to each other to release the spring piece.
[0048] Furthermore, the loading module 100 of this application can achieve stable contact between the spring sheet and the inner wall of the cylindrical component, so that the subsequent welding module 400 can successfully complete the welding between the spring sheet and the cylindrical component.
[0049] In a further embodiment of the invention, reference is made to... Figure 11 The fourth drive structure 122 is a first spring. The pressure claw 121 is slidably disposed on the fixture body 110 along the radial direction of the mounting hole 110a. The opposite ends of the first spring are connected to the pressure claw 121 and the fixture body 110 respectively, and are used to provide elastic force to keep the pressure claw 121 close to the positioning area 110b.
[0050] It is understandable that when the spring sheet is placed on the support part 111, an external force is applied to the pressure claw 121 so that the pressure claw 121 can overcome the elastic force of the first spring, thereby the pressure claw 121 can move away from the positioning area 110b. After the spring sheet is placed on the support part 111, the external force applied to the pressure claw 121 is removed. At this time, under the action of the elastic force of the first spring, the pressure claw 121 can move closer to the positioning area 110b, thereby completing the contact between the spring sheet and the inner wall of the cylindrical part.
[0051] In some embodiments of the present invention, reference is made to Figure 7 and Figure 8The loading module 100 also includes a locking assembly 130, which is detachably connected to the fixture body 110. The locking assembly 130 includes a fifth drive structure 131 and a plurality of locking elements 132. The plurality of locking elements 132 are circumferentially spaced around the mounting hole 110a. The fifth drive structure 131 is connected to each locking element 132 respectively and is used to drive the locking elements 132 to move closer or further away from each other to lock or release the cylindrical part in the positioning area 110b. The assembly module 300 is used to realize the installation or removal of the locking assembly 130 on the fixture body 110.
[0052] It should be noted that although the cylindrical part can be positioned within the positioning area 110b, the cylindrical part is subject to positional displacement due to the sequential order in which the pressure claws 121 push the spring sheet to fit the cylindrical part. In this case, although the spring sheet can fit the inner wall of the cylindrical part, the position of the cylindrical part will be offset, thus affecting the welding accuracy between the cylindrical part and the spring sheet in the subsequent welding module 400.
[0053] It is understood that in the loading module 100 of this application, by setting the locking component 130, after the cylindrical part is positioned in the positioning area 110b and the spring is assembled into the cylindrical part, the assembly module 300 can transport the locking component 130 to the fixture body 110 so that the locking component 130 is connected to the fixture body 110. Then, under the drive of the fifth drive structure 131, each locking component 132 can move closer to each other to lock and fix the cylindrical part in the positioning area 110b. Thus, after the pressure claw 121 achieves the fit between the spring and the cylindrical part, the positional offset of the spring can be smaller, thereby improving the welding accuracy between the cylindrical part and the spring.
[0054] Further reference Figure 1 The welding system also includes a temporary storage module 800 for storing the locking component 130. The assembly module 300 also includes a clamping component 330 for clamping the locking component 130. The drive end of the drive component 310 is connected to the clamping component 330.
[0055] Therefore, before loading the cylindrical component onto the loading module 100, the assembly module 300 can transfer the locking component 130 from the fixture body 110 to the temporary storage module 800. At this time, the cylindrical component can be smoothly loaded into the positioning area 110b, and the spring can be smoothly assembled into the inner cavity of the cylindrical component. Then, the assembly module 300 can transfer the locking component 130 from the temporary storage module 800 to the fixture body 110, so that the locking component 130 can lock and fix the cylindrical component, and the edge subsequent welding module 400 welds the cylindrical component and the spring.
[0056] In some embodiments of the present invention, reference is made to Figure 12 and Figure 13 The locking assembly 130 also includes a third mounting base 133. Multiple locking elements 132 include a first locking element 132A and a second locking element 132B located on the left and right sides of the mounting hole 110a. Both the first locking element 132A and the second locking element 132B are slidably mounted on the third mounting base 133 in the left-right direction. The fifth driving structure 131 includes a driving element 131a, a first transmission arm 131b, and a second transmission arm 131c. The driving element 131a is slidably mounted on the third mounting base 133 in the front-back direction. The driving element 131a is connected to the first locking element 132A via the first transmission arm 131b, and to the second locking element 132B via the second transmission arm 131c. Under external force, the driving element 131a can slide in the front-back direction, thereby driving the first locking element 132A and the second locking element 132B closer to or further away from each other via the first transmission arm 131b and the second transmission arm 131c, respectively.
[0057] Furthermore, when the driving member 131a slides backward under the action of external force, the driving member 131a can drive the first locking member 132A and the second locking member 132B to move closer to each other through the first transmission arm 131b and the second transmission arm 131c, so that the first locking member 132A and the second locking member 132B can cooperate to clamp and fix the cylindrical member in the positioning area 110b; when the driving member 131a slides forward under the action of external force, the driving member 131a can drive the first locking member 132A and the second locking member 132B to move away from each other through the first transmission arm 131b and the second transmission arm 131c, so that the first locking member 132A and the second locking member 132B cooperate to release the cylindrical member in the positioning area 110b.
[0058] It is understandable that by setting the first transmission arm 131b and the second transmission arm 131c, a single driving member 131a can synchronously drive the first locking member 132A and the second locking member 132B to move synchronously through the first transmission arm 131b and the second transmission arm 131c.
[0059] In some embodiments of the present invention, reference is made to Figure 13 The fifth drive structure 131 also includes a second spring 131d, which is connected to the drive member 131a and the third mounting base 133 respectively. The drive member 131a has a locked state and an unlocked state. When the drive member 131a is in the locked state, the first locking member 132A and the second locking member 132B move closer to each other to clamp the cylindrical member. When the drive member 131a is in the unlocked state, the first locking member 132A and the second locking member 132B move further apart to release the cylindrical member. The second spring 131d is used to provide the elastic force to keep the drive member 131a in the locked state.
[0060] For example, when the drive member 131a moves backward to switch to the locking state, the first locking member 132A and the second locking member 132B move closer to each other to clamp the cylindrical member in the positioning area 110b; when the drive member 131a moves forward to switch to the releasing state, the first locking member 132A and the second locking member 132B move further apart to release the cylindrical member in the positioning area 110b.
[0061] Understandably, the second spring 131d is connected to the drive member 131a and the third mounting base 133 respectively, and is used to provide an elastic force to keep the drive member 131a moving backward. Thus, under normal circumstances, the drive member 131a can be kept in a locked state under the action of the second spring 131d. Consequently, the first locking member 132A and the second locking member 132B can automatically complete the clamping and fixing of the cylindrical part in the positioning area 110b under the action of the second spring 131d.
[0062] To achieve a detachable connection between the locking assembly 130 and the fixture body 110, in some embodiments of the present invention, reference is made to... Figure 8 , Figure 9 , Figure 12 and Figure 13 The third mounting base 133 is provided with an insertion hole 133a, and the fixture body 110 is provided with an insertion post 113, which is slidably inserted into the insertion hole 133a; the locking assembly 130 also includes a locking structure 134, which can lock the insertion post 113 into the insertion hole 133a.
[0063] Understandably, when it is necessary to install the locking assembly 130 on the fixture body 110, the insert post 113 can be inserted into the insert hole 133a, and then the locking structure 134 can lock the insert post 113 in the insert hole 133a, thereby realizing the connection between the locking assembly 130 and the fixture body 110; when it is necessary to remove the locking assembly 130 from the fixture body 110, the locking structure 134 releases the locking of the insert post 113 in the insert hole 133a, and at this time, the locking assembly 130 can smoothly detach from the fixture body 110 in the vertical direction under the action of external force.
[0064] In a further embodiment of the invention, reference is made to... Figure 9 and Figure 13 The insertion post 113 is provided with a snap-fit groove 113a. The locking structure 134 includes a snap-fit member 134a, which is movably disposed on the third mounting base 133. Under the action of external force, the snap-fit member 134a can be inserted into the snap-fit groove 113a to lock the insertion post 113 into the insertion hole 133a, or the snap-fit member 134a can be disengaged from the snap-fit groove 113a to release the insertion post 113.
[0065] Understandably, when it is necessary to lock the insertion post 113 into the insertion hole 133a, the snap fastener 134a can be driven by external force to pass through the snap fastener groove 113a of the insertion post 113. At this time, the snap fastener 134a can prevent the insertion post 113 from moving along the insertion hole 133a, so as to achieve the locking and fixation of the insertion hole 133a within the insertion hole 133a. When it is necessary to release the locking and fixation of the insertion post 113 within the insertion hole 133a, the snap fastener 134a can be driven by external force to disengage from the snap fastener groove 113a on the insertion post 113. At this time, the insertion post 113 can move smoothly along the insertion hole 133a, so that the insertion post 113 can smoothly disengage from the insertion hole 133a.
[0066] In some embodiments of the present invention, reference is made to Figure 13 The locking structure 134 also includes a third spring 134b, which is connected to the third mounting base 133 and the snap-fit member 134a respectively, and is used to provide the elastic force to keep the snap-fit member 134a snapped into the snap-fit groove 113a.
[0067] Understandably, under the elastic force of the third spring 134b, the snap-fit member 134a can remain inserted into the snap-fit groove 113a, thereby locking the insertion post 113 into the insertion hole 133a; under the action of external force, the snap-fit member 134a can overcome the elastic force of the third spring 134b to disengage from the snap-fit groove 113a, at which point the insertion post 113 can smoothly disengage from the insertion hole 133a.
[0068] In a further embodiment of the present invention, the snap-fit member 134a is provided with a guide slope.
[0069] Understandably, during the process of inserting the insertion post 113 into the insertion hole 133a, the insertion post 113 can abut against the guide slope, thereby pushing the snap-fit member 134a away from the insertion hole 133a to avoid the insertion post 113. When the insertion post 113 extends into the insertion hole 133a, and the snap-fit groove 113a on the insertion post 113 is aligned with the snap-fit member 134a, under the elastic force of the third spring 134b, the snap-fit member 134a can extend into the snap-fit groove 113a to achieve locking and fixing of the insertion post 113.
[0070] In some embodiments of the present invention, reference is made to Figure 12 and Figure 13 The locking assembly 130 also includes a clamping structure 135. The third mounting base 133 is provided with a vertically extending loading hole 133c, which is used to load the spring piece. The clamping structure 135 includes a jaw 135a and a fourth spring 135b. The fourth spring 135b is connected to the jaw 135a and the third mounting base 133 respectively. Under the elastic force of the fourth spring 135b, the jaw 135a can cooperate with the hole wall of the loading hole 133c to clamp the spring piece.
[0071] It is understandable that the spring can be loaded into the loading hole 133c and clamped and fixed by the gripper 135a and the hole wall of the loading hole 133c. After the locking assembly 130 is installed on the fixture body 110, the spring in the loading hole 133c can be just supported on the support part 111.
[0072] In some embodiments of the present invention, reference is made to Figures 7 to 9 The fixture body 110 is also provided with an elastic buffer 114, which is connected to the fixture body 110 and the third mounting base 133 respectively, and is used to provide the third mounting base 133 with an elastic buffer force along the axial direction of the insertion post 113.
[0073] It is understandable that by providing the elastic buffer 114, the elastic buffer 114 can provide elastic buffering force when the third mounting base 133 is mounted on the fixture body 110, so as to protect the third mounting base 133 and the fixture body 110.
[0074] In a further embodiment of the invention, reference is made to... Figure 9 The fixture body 110 is provided with a vertically extending guide post 115, the third mounting base 133 is provided with a guide hole 133b adapted to the guide post 115, and the elastic buffer 114 is sleeved on the guide post 115.
[0075] It is understandable that the guide post 115 and guide hole 133b enable the third mounting base 133 to be accurately installed on the fixture body 110; by fitting the elastic buffer 114 onto the guide post 115, the guide post 115 can horizontally limit the elastic buffer 114, so that the elastic buffer 114 can accurately deform in the vertical direction and accurately provide elastic buffering force in the vertical direction.
[0076] In some embodiments of the present invention, reference is made to Figure 1 The welding system also includes a loading module 500 and a unloading module 600. The loading module 500 is used to load the cylindrical part onto the loading module 100, and the unloading module 600 is used to unload the cylindrical part with the welded spring sheet from the loading module 100.
[0077] In some embodiments of the present invention, reference is made to Figure 1The welding system also includes a first storage module 900, a second storage module 1000, a third storage module 1100, and a replenishing module 1200. The first storage module 900 stores cylindrical parts, the second storage module 1000 stores spring pieces, and the third storage module 1100 stores cylindrical parts with welded spring pieces. The loading module 500 can load the cylindrical parts in the first storage module 900 onto the loading module 100. The replenishing module 1200 can load the spring pieces in the second storage module 1000 into the forming area. The unloading module 600 can unload the cylindrical parts with welded spring pieces from the loading module 100 into the third storage module 1100.
[0078] Further reference Figure 1 The welding system also includes a transfer module 700, on which a loading module 100 is mounted. The transfer module 700 drives the loading module 100 to pass sequentially through the feeding module 500, the assembly module 300, the welding module 400, and the unloading module 600.
[0079] Specifically, the transfer module 700 is a turntable.
