Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of welding, in particular to a welding equipment for processing a volute fan. BACKGROUND

[0002] The fan belongs to the category of general machinery. The volute, as an indispensable basic element of the centrifugal fan, collects high-speed airflow from the fan impeller and guides the high-speed airflow to the exhaust port. Since the volute affects the flow of the air flow field, the structure of the volute directly affects the efficiency of the fan. When welding the volute fan, the two side plate structures need to be fixed to the middle cylindrical structure, and then welded and fixed by the welding equipment, and finally form the volute fan shell.

[0003] The prior art document CN119525858A discloses a welding equipment for processing a volute fan. By adjusting the installation position of the positioning block, the fixing height of the pressing plate can be changed, thereby making the fixing device suitable for more models of volute fans and achieving the effect of quick installation. However, in actual use, since the shell in the middle of the volute is large, the sparks generated during welding are very easy to splash onto the outer surface of the middle shell. Since the large shell requires a long welding time, the volute will continue to be splashed by sparks during welding, causing serious burn marks on the outer surface. Therefore, post-processing is required after processing, and improvement is needed. SUMMARY

[0004] In view of the problem that the volute is easily burned by sparks during welding processing in the prior art, the technical solution adopted by the present application is as follows: a welding equipment for processing a volute fan, comprising:

[0005] A front top table is provided with a processing equipment on the top;

[0006] A rear bottom table is provided with a volute shell on the top;

[0007] The volute shell comprises:

[0008] A sleeve part is provided with a pressing part on both upper and lower sides. Before welding, the volute with a side cover on both upper and lower sides is placed in the sleeve part, and then the pressing part is installed on both upper and lower sides of the sleeve part. The volute shell is placed on the axial part of the upper surface of the rear bottom table.

[0009] The pressing part comprises:

[0010] A sliding cover body is provided with a ring slot on both sides of the top of the inner cavity;

[0011] The traction bottom plate is provided with a tension spring barrel at the top, and the top end of the tension spring barrel is inserted into the bottom of the sliding cover body. An annular groove is formed on the outer surface of the traction bottom plate for external fixation. The traction bottom plate can be attracted to the magnet at the top end of the tension spring barrel by magnetic force, so that the tension spring barrel is retracted, and the effect of traction sliding cover body is achieved.

[0012] The bottom of the inner cavity of the shaft control disc is uniformly provided with a control roller, and the top of the shaft control disc is provided with a suction disc hole. The shaft control disc drives the control roller to rotate through the internal motor.

[0013] Further, the pressurizing component further comprises:

[0014] The built-in detection head is uniformly arranged at the shaft center of the top inner cavity of the sliding cover body.

The outer surface of the magnetic attraction sliding ball is inserted into the outer surface of the traction bottom plate through the clamping groove. After the clamping inner ring is powered on, the magnetic attraction sliding ball can be synchronously pushed out to the side close to the traction bottom plate through the magnetic attraction effect. At this time, the magnetic attraction sliding ball is protruding, as shown in Figure 5 , and is inserted into the annular groove of the traction bottom plate, thereby achieving the effect of fixing the traction bottom plate. After the clamping inner ring is powered off, the magnetic attraction sliding ball is no longer inserted into the annular groove of the traction bottom plate due to the extrusion force, and the traction bottom plate can be easily pulled out from the inside of the insertion sliding groove.

[0019] Further, the sleeve component further comprises:

[0027] The control rotating wheels are symmetrically arranged on the left and right sides of the inner cavity of the flat tray, and the outer surface of the control rotating wheels is engagedly connected with the outer surface of the rotating suction disc.

[0028] Further, the processing equipment comprises:

[0029] The lower surface of the horizontal guide rail is fixedly connected with the outer surface of the front top table;

[0030] The control sliding box is provided with a moving roller shaft symmetrically inserted into the front and rear ends of the rotating shaft of the control sliding box;

[0032] Further, the processing equipment further comprises:

[0033] The bottom of the vertical guide rail is fixedly connected with the upper surface of the control sliding box;

[0034] The upper and lower ends of the guide screw rod are inserted into the inner wall of the vertical guide rail;

[0035] The mobile sliding plate is internally provided with a threaded rotating drum which is threadedly connected with the outer surface of a guide threaded rod, and the outer surface of the mobile sliding plate is slidably connected with the inner wall of the vertical guide rail through wall-adhering rollers, and the mobile sliding plate is controlled to rotate by the internal motor, so that the threaded rotating drum slides along the guide threaded rod, thereby achieving the vertical sliding effect.

[0036] The welding module is arranged on the outer surface of the mobile sliding plate and is used for welding the volute.

[0037] Further, the welding module comprises:

[0038] The extended threaded rod is symmetrically arranged on the outer surface of the mobile sliding plate away from the vertical guide rail.

[0039] The control propeller is threadedly connected with the outer surface of the extended threaded rod on both sides of the inner wall.

[0040] The segmented sliding plate is inserted into the middle part of the upper surface of the control propeller at the bottom end, and the segmented sliding plate is combined by a bottom plate and a top sliding sleeve, and the top sliding sleeve can vertically slide along the outer surface of the bottom plate under the control of the top roller of the bottom plate.

[0041] Further, the welding module further comprises:

[0042] The rotating connecting drum is fixedly connected with the upper part of the outer surface of the segmented sliding plate.

[0043] The welding end is inserted into the axis of the outer surface of the rotating connecting drum, and the end of the welding end away from the rotating connecting drum extends to the inside of the sliding cover through the ring cutting groove.

[0044] The beneficial effects of the present application are as follows:

[0045] 1. The device can automatically heat-weld the volute and the baffle inside the volute sleeve through the welding module. Since the volute is always located inside the sliding cover during welding, only the ring cutting groove is reserved as a welding slot, so that sparks generated during welding cannot splash onto the outer surface of the middle shell, thereby protecting the outer surface of the volute, avoiding the problem that the volute will continuously be splashed by sparks during welding, resulting in serious burn marks on the outer surface, eliminating subsequent processing work, and thereby optimizing the welding work.

[0046] 2. The volute shell cover is assembled and mounted on the upper part of the rear base, so it can adapt to different models of volute for welding work, and it is also convenient to disassemble the volute shell cover for subsequent maintenance work. When the assembled volute is inside the volute shell cover, the baffle can be further moved by the shaft control disc on the upper and lower sides, so that the baffle can be accurately aligned with the volute arc edge, avoiding the problem that the side plate is misaligned with the volute at too large an angle when the volute assembly is installed, so that the quality of the welded volute is unqualified.

[0047] 3. In the welding process, since the contact point of the welding module and the volute is always located inside the ring cutting groove, the toxic fumes generated during welding will definitely be sucked away by the continuously working side edge dust collector when they diffuse to the outside, thereby greatly reducing the problem of environmental pollution caused by welding toxic gas. When the side plate is working, it will be in contact with the welding module and be extruded, which will cause the side plate to slip. At this time, the magnetic attraction of the traction base plate can further reinforce the extrusion force of the side plate and the volute, thereby preventing the side plate from being pushed by the welding module and causing misalignment.

[0048] 4. The control propeller moves further along the outer surface of the extended threaded rod to the direction close to the welding point, achieving the effect of secondary distance adjustment. Since the threaded groove of the extended threaded rod is more precise, the control propeller can move with higher precision, so that when the welding end is in contact with the volute welding point, it will not collide or be severely extruded due to excessive speed. The rotating cylinder can rotate the welding end to avoid the problem that the welding end always welds continuously with a single contact point, reducing the wear of the welding end.

The embodiments of the application are given for illustrative and descriptive purposes only and are not intended to be exhaustive or to limit the application to the forms disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. Embodiments were chosen and described in order to best explain the principles of the application and its practical application, and to enable others skilled in the art to understand the application for various embodiments with various modifications as are suited to the particular use contemplated.

[0059] Embodiment 1, please refer to Figures 1-5 The application provides a technical solution: a welding equipment for volute fan processing, comprising:

[0060] The front top stand 2 is provided with the processing equipment 3 on the top of the front top stand 2;

[0061] The rear bottom stand 1 is provided with the volute shell 4 on the top of the rear bottom stand 1;

[0062] The volute shell 4 comprises:

[0063] The sleeve component 41 is provided with the pressurizing component 42 on both upper and lower sides of the sleeve component 41, before welding work, the volute provided with side covers on both upper and lower sides is placed in the interior of the sleeve component 41, then the pressurizing component 42 is installed on both upper and lower sides of the sleeve component 41, and the volute shell 4 is placed on the shaft center part of the upper surface of the rear bottom stand 1;

[0064] The pressurizing component 42 comprises:

[0065] The sliding cover 421 has symmetrically formed annular grooves 422 on both sides of the top of the inner cavity of the sliding cover 421;

[0066] The traction base plate 424 has a tension spring cylinder 423 on its top, and the top of the tension spring cylinder 423 is inserted into the bottom of the sliding cover 421. The outer surface of the traction base plate 424 has an annular groove for external fixation. The traction base plate 424 can magnetically attract the magnet at the top of the tension spring cylinder 423, thereby causing the tension spring cylinder 423 to retract and achieve the effect of traction of the sliding cover 421.

[0067] The shaft control disk 427 has control rollers 428 evenly arranged at the bottom of its inner cavity, and a suction cup hole is opened at the top of the shaft control disk 427. The shaft control disk 427 drives the control rollers 428 to rotate through an internal motor.

[0068] The pressurizing component 42 also includes:

[0069] Built-in probes 426 are evenly distributed at the axis at the top of the inner cavity of the sliding cover 421. The built-in probes 426 can observe the parts of the volute and the edge of the side cover, thereby assisting the axis control disk 427 in controlling the side cover to move.

[0070] The side vacuum cleaner 425 is symmetrically inserted into the left and right sides of the top of the inner cavity of the sliding cover 421 through the annular groove 422, and is used to absorb the fumes generated during welding.

[0071] Sleeve component 41 includes:

[0072] The inner cavity of the covered cylindrical shell 411 is symmetrically provided with insertion grooves on the upper and lower sides, and the inner cavity of the insertion groove is provided with a receiving slot 412.

[0073] Two sets of snap-fit ​​inner rings 413 are symmetrically arranged on the upper and lower sides of the inner cavity of the covering shell 411 via receiving slots 412. Magnetic sliding balls are evenly distributed on the inner wall of the snap-fit ​​inner rings 413, and the outer surface of the magnetic sliding balls is inserted into the outer surface of the traction base plate 424 through the slots. When the snap-fit ​​inner rings 413 are energized, the magnetic sliding balls can be simultaneously pushed towards the side closer to the traction base plate 424 through magnetic attraction. At this time, the magnetic sliding balls bulge out, as... Figure 5 As shown, the magnetic ball is inserted into the annular groove of the traction base plate 424, thereby achieving the effect of fixing the traction base plate 424. After the inner ring 413 is de-energized, the magnetic ball is no longer inserted into the annular groove of the traction base plate 424 due to the squeezing force, and the traction base plate 424 can be easily pulled out from the inside of the insertion groove.

[0074] Sleeve component 41 also includes:

[0075] The outer pressurizing ring 414 is sleeved with the middle part of the outer surface of the covering barrel shell 411, and the upper and lower sides of the outer surface of the outer pressurizing ring 414 are symmetrically provided with air inlet ports, and the middle part of the inner cavity of the outer pressurizing ring 414 is provided with an air outlet port;

[0076] The transverse compression rod 415 is slidably connected with the middle part of the inner cavity of the covering barrel shell 411 through the penetrating port on the outer surface of the transverse compression rod 415, and the outer pressurizing ring 414 directly pressurizes the transverse compression rod 415, so that the transverse compression rod 415 is elongated;

[0077] The inner clamping soft plate 416 is inserted with the middle part of the outer surface of the inner clamping soft plate 416 at one end of the transverse compression rod 415, and the other end of the transverse compression rod 415 is inserted with the middle part of the inner cavity of the outer pressurizing ring 414 through the air outlet port.

[0078] Before the device is used for the side plate welding work of the volute, the volute sleeve 4 is combined and installed on the top of the rear base table 1, the lower pressurizing component 42 is first inserted into the lower accommodating clamping groove 412 of the covering barrel shell 411, then the clamping inner ring 413 of the lower part is clamped and fixed by pushing the clamping ball, then the volute sleeve 4 in this state is placed on the top of the rear base table 1, then the lower side plate, the volute and the upper side plate are placed from bottom to top in the inside of the volute sleeve 4, after the placement is completed, the upper pressurizing component 42 is installed, then the outer pressurizing ring 414 pressurizes the transverse compression rod 415 to push the inner clamping soft plate 416 in the middle part of the covering barrel shell 411, so as to clamp the side of the volute body, and the magnetic attraction of the traction base plate 424 makes the sliding cover body 421 slide to the position close to the side plate, so as to press the upper and lower side plates to the volute part, and the preparation work is completed.

[0079] After the volute and the side plate are located in the inside of the volute sleeve 4, before the welding work is carried out, the position of the side plate needs to be adjusted to ensure that the arc edge of the side edge is aligned with the arc edge of the volute, at this time, the control rollers 428 of the shaft center control discs 427 on the upper and lower sides are controlled to drive the upper and lower side plates to slide relative to the volute, the alignment of the arc edges is monitored by the built-in detection head 426, so as to ensure that the volute can be perfectly connected with the side plate, then the traction base plate 424 increases the magnetic force to increase the contact extrusion force of the control roller 428 to the side plate, so as to temporarily fix the side plate.

[0080] The welding module 5 of the processing equipment 3 is connected with the sliding cover 421 through the ring cutting groove 422, and the joint position of the volute and the cover shell is subjected to hot welding work. The sparks generated by welding are blocked by the sliding cover 421, avoiding contacting the internal volute, and playing a protective role. When the welding module 5 completely scans the ring cutting groove 422, it represents that the welding of the volute at the position of the ring cutting groove 422 is completed. Then, the shaft control disc 427 on the upper and lower sides is rotated to control the rotating roller 428, so that the volute rotates to switch the welding position of the volute, and the above welding work is repeated until the volute is welded.

[0081] After the volute is welded, the upper pressing part 42 is removed, the volute is taken out, and then the volute and the side plate are installed to realize the welding work of the next group of volutes.

[0091] The processing device 3 further comprises:

[0092] A vertical guide rail 35, the bottom of which is fixedly connected with the upper surface of the control sliding box 32;

[0093] A guide threaded rod 37, both upper and lower ends of which are inserted with the inner wall of the vertical guide rail 35;

[0096] The welding module 5 comprises:

[0097] An extension threaded rod 51 symmetrically arranged on the side of the outer surface of the moving sliding plate 36 away from the vertical guide rail 35;

[0098] A control propeller 52, both sides of the inner wall of which are threadedly connected with the outer surface of the extension threaded rod 51;

[0099] A segmented sliding plate 53, the bottom end of which is inserted with the middle part of the upper surface of the control propeller 52, the segmented sliding plate 53 is composed of a bottom plate and a top sliding sleeve, and the top sliding sleeve can vertically slide along the outer surface of the bottom plate under the control of the top roller of the bottom plate.

[0100] The welding module 5 further comprises:

[0101] A rotating cylinder 54, the middle part of the outer surface of which is fixedly connected with the upper part of the outer surface of the segmented sliding plate 53;

[0103] During the welding process, since the contact point of the welding module 5 with the volute is always located inside the ring cutting groove 422, the toxic fumes generated by welding will definitely be sucked away by the side edge dust collector 425 working continuously when diffusing to the outside, thereby greatly reducing the problem of welding toxic gas polluting the environment.

[0105] The control sliding box 32 drives the transmission chain 34 to slide horizontally along the inner wall of the horizontal guide rail 31 by rotating the moving roller shaft 33, and then the moving sliding plate 36 is driven to slide vertically along the guide screw rod 37, so that the front coordinates of the extension screw rod 51 can be adjusted.

[0106] The control pusher 52 is further moved along the outer surface of the extension screw rod 51 to the direction close to the welding position, so that the secondary distance adjustment effect is realized. Since the thread groove of the extension screw rod 51 is more precise, the control pusher 52 can also move with higher precision, so that when the welding end 55 contacts the volute welding position, the problem of impact or serious extrusion caused by too fast speed can be avoided. The rotating cylinder 54 can rotate the welding end 55, so that the welding end 55 does not always perform the welding work with a single contact point, and the loss of the welding end 55 is reduced.
