Description

Technical Field

[0001] The present invention relates to the technical field of fan volute processing, and in particular to a processing device for producing fan accessories. Background Art

[0002] The volute of a centrifugal fan is welded together by two side plates and a volute plate. In the existing process of processing the volute of a centrifugal fan, it is necessary to manually hold the volute plate and the side plates, align the volute plate and the side plates, and then spot weld them together through a welding mechanism. In the process of spot welding the volute plate and the side plates, it is also necessary to manually adjust the position of the volute plate and the side plates to avoid positional offset of the volute plate and the side plates after welding, which affects the quality of the centrifugal fan volute after processing. In addition, when spot welding the volute plate and the side plates, it is also necessary to manually flip the volute plate and the side plates to adjust the spot welding position of the volute plate and the side plates, which is labor-intensive.

[0003] In addition, due to the complex shapes of the side panels and the volute panel, and the volute panel is a soft stainless steel panel, it is difficult to align the volute panel and the side panels, and deviation and misalignment are prone to occur during the welding process. Moreover, since the existing welding mechanism has two upper and lower welding heads, and the welding heads are fixed, the welding area cannot be well pressed during the welding process, resulting in the volute panel and the side panels being easily offset during welding, affecting the horizontality of the side panels and the volute panel, and making the welds uneven. Secondly, since the volute tongue corner of the volute is narrow and the two welding heads are fixed, it is difficult to move the volute left and right, front and back, or adjust the tilt angle as needed, resulting in the inability to fix and weld the volute corner well, and the welding at the corner is prone to being unreliable. Summary of the Invention

[0004] In order to overcome the shortcomings of being difficult in aligning the volute plate and the side plate, prone to deviation and misalignment during welding, inability to tighten the welding area well during welding, and difficulty in horizontally shifting the volute left and right, front and back, or adjusting the tilt angle as required, the present invention provides a processing device for the production of fan accessories.

[0009] As an improvement to the above solution, limit blocks are provided on the left and right sides of the first extrusion roller.

[0038] The first squeezing roller 304 and the two second squeezing rollers 404 are each provided with two bilaterally symmetrical through grooves to avoid affecting the welding of the outer welding head 4 and the inner welding head 5 to the volute.

[0039] Limiting blocks 30401 are provided on the left and right sides of the first squeezing roller 304 . The diameter of the limiting blocks 30401 is larger than the diameter of the first squeezing roller 304 , and the distance between the two limiting blocks 30401 is the same as the left and right width of the volute.

[0040] The surfaces of the first squeezing roller 304 and the two second squeezing rollers 404 are both adhered with a rubber layer to avoid damage to the volute plate 8 and the left plate 6 and the right plate 7 .

[0041] In the prior art, it is necessary to manually hold the volute plate 8 and the left side plate 6 and the right side plate 7, and align the volute plate 8 and the left side plate 6 and the right side plate 7, and then spot weld them through a welding mechanism. In addition, the volute plate 8 is a soft stainless steel plate, which will vibrate during the welding process, requiring workers to constantly adjust it to ensure the welding quality. When the present invention is working, the left side plate 6 and the right side plate 7 are first placed on the corresponding conveying plate 2, and the first corner 6002 of the left side plate 6 and the second corner 7002 of the right side plate 7 are placed forward, and the external air pump is started at the same time, and the suction cup on the conveying plate 2 is used to align the left side plate 6 and the right side plate 7. The plate 6 is adsorbed and fixed, and then the first driving member 101 is controlled to drive the corresponding conveying plate 2 to move to the right and left respectively, so that the corresponding conveying plate 2 drives the left plate 6 and the right plate 7 to gradually fit together. In this process, the volute plate 8 is manually placed between the left plate 6 and the right plate 7 with the volute tongue 8001 facing forward, so that in the process of the left plate 6 and the right plate 7 gradually fitting together, the left plate 6 and the right plate 7 fix the volute plate 8. It is explained here that in the process of the left plate 6 and the right plate 7 fixing the volute plate 8, the position of the volute plate 8 is manually adjusted so that the left plate 6, the right plate 7 and the volute plate 8 are as shown in FIG. Figure 1In the state shown, the volute tongue 8001 is aligned with the first folded corner 6002 and the second folded corner 7002, and the volute plate 8 is located on the inner side of the first folded edge 6001 and the second folded edge 7001, so that the volute plate 8 is limited so that the volute plate 8 will not vibrate significantly during subsequent welding, thereby avoiding the need for workers to constantly adjust the positions of the left plate 6, the right plate 7 and the volute plate 8. At the same time, it also avoids the need to manually hold the left plate 6, the right plate 7 and the volute plate 8 all the time, effectively reducing the labor intensity of the workers. In addition, the left plate 6, the right plate 7 and the volute plate 8 are combined to form a volute, and the corresponding second fixing frame 401, the second fixing plate 402, the fifth driving member 403 and the second squeezing roller 404 and other parts are located in the air outlet of the volute;

[0042] Moreover, in the prior art, before welding the volute, it is necessary to manually press the left side plate 6 and the right side plate 7 and the volute plate 8 together and then weld them. Due to the complex shape of the volute, it is difficult to press the left side plate 6 and the right side plate 7 and the volute plate 8 at the front edge of the volute tongue 8001, so that before welding, the left side plate 6 and the right side plate 7 and the volute plate 8 cannot be tightly fitted, affecting the welding quality. The present invention is based on the view from left to right, and controls the motor connected to the second fixing bracket 401 at the air outlet of the volute to drive the corresponding second fixing plate 402 to rotate counterclockwise. The needle rotates, and the second fixed plate 402 drives the corresponding inner welding head 5 to rotate, so that the inner welding head 5 rotates to be perpendicular to the volute tongue 8001 on the volute plate 8, and then controls the third driving member 204 to push the second fixed frame 401 backward, and drives the corresponding second fixed plate 402 and the second squeezing roller 404 to move backward through the second fixed frame 401, so that the second squeezing roller 404 moves to above the front edge of the volute tongue 8001. Since the second squeezing roller 404 is initially located above the volute tongue 8001, the second electric slider 203 is controlled to move on the arc slide rail 3. The third driving member 204 and the parts connected thereto are driven to move downward, so that the second squeezing roller 404 moves downward until it fits the volute plate 8. At the same time, based on the left-to-right view, the motor connected to the first fixing frame 301 is controlled to drive the first fixing plate 302 to rotate clockwise, so that the outer welding head 4 is perpendicular to the volute plate 8, and the fourth driving member 303 is controlled to drive the first squeezing roller 304 to move rightward to below the volute tongue 8001. Then, the first electric slider 201 is controlled to drive the second driving member 202 to move upward, and the second driving member 202 drives the first fixing frame 301 to rotate clockwise. 01 moves upward, the first fixing frame 301 drives the first fixing plate 302 to move upward, and then the first fixing plate 302 drives the first squeezing roller 304 to move upward until it fits with the lower side of the volute tongue 8001, so that the left side plate 6 and the right side plate 7 and the volute plate 8 are clamped and squeezed by the first squeezing roller 304 and the second squeezing roller 404, so that the left side plate 6 and the right side plate 7 and the volute plate 8 are tightly fitted at the front edge of the volute tongue 8001, and the front edge of the volute tongue 8001 is limited and fixed, so as to facilitate subsequent welding and effectively ensure the welding quality;

[0043] In order to prevent the left plate 6 and the right plate 7 from offsetting with the volute plate 8 during welding, affecting the horizontality of the left plate 6 and the right plate 7 with the volute plate 8 and making the welding place uneven, the present invention controls the fourth driving member 303 to push the outer welding head 4 upward until it contacts the volute plate 8 to achieve welding at this place, and at the same time controls the fifth driving member 403 to push the inner welding head 5 downward until it contacts the first folding edge 6001 and the second folding edge 7001, and achieves welding at this place through the cooperation of the outer welding head 4 and the inner welding head 5, and then controls the fourth driving member 303 and the fifth driving member 403 respectively to drive the outer welding head 4 and the inner welding head 5 to reset, in order to To make the spot welding spacing of the volute uniform, by controlling the third driving member 204 and the second driving member 202, respectively drive the inner welding head 5 and the outer welding head 4 to move a certain distance in the direction close to the first corner 6002 and the second corner 7002, the inner welding head 5 and the outer welding head 4 move a fixed distance each time, so that the spot welding spacing of the volute is uniform, ensuring the welding quality of the volute, and then respectively control the fourth driving member 303 and the fifth driving member 403 to drive the outer welding head 4 and the inner welding head 5 to move upward and downward, and so on, to achieve welding on the lower side of the volute outlet, and in this process, since the volute outlet has a certain curvature, in order to make the outer welding head 4 and the inner welding head The welding point between the head 5 and the volute plate 8 always maintains a vertical angle, thereby ensuring the welding quality of the volute. During the welding process, the first fixed plate 302 and the second fixed plate 402 are respectively controlled by the motor to rotate to ensure that the welding points between the outer welding head 4 and the inner welding head 5 and the volute plate 8 are always vertical, effectively ensuring the welding quality of the volute. In addition, since the volute plate 8 is relatively thin, it is easy to deform during stacking and transportation, so that the volute plate 8 cannot fit tightly with the left plate 6 and the right plate 7. Therefore, during the backward movement of the first squeezing roller 304 and the second squeezing roller 404, the volute plate 8 is clamped between the first squeezing roller 304 and the second squeezing roller 404 through the cooperation of the first squeezing roller 304 and the second squeezing roller 404. 304 and the second squeezing roller 404, when the first squeezing roller 304 and the second squeezing roller 404 are pushed backward respectively by the second driving member 202 and the third driving member 204, the first squeezing roller 304 and the second squeezing roller 404 will squeeze the volute plate 8, guide and correct the volute plate 8, and ensure that the volute plate 8 can fit tightly with the left plate 6 and the right plate 7. At the same time, during the volute welding process, the left plate 6 and the right plate 7 are limited left and right by the limiting block 30401 on the first squeezing roller 304, thereby effectively preventing the left plate 6 and the right plate 7 from deviating left and right during the welding process, affecting the fitting level of the side plate and the volute plate 8, and causing the problem of uneven welding.

[0044] In order to effectively ensure the welding quality of the volute at the first corner 6002 and the second corner 7002, and to prevent the left plate 6 and the right plate 7 from not fitting tightly with the volute plate 8 at this location, resulting in the volute corner welding being unreliable, such as Figure 5 As shown, when the outer welding head 4 moves to the lower side of the first folding angle 6002 and the second folding angle 7002, the motor is controlled to drive the rotating roller 501 to rotate, and the sixth driving member 502 is driven to rotate by the rotating roller 501, and the corresponding second fixing frame 401 is driven to rotate by the sixth driving member 502. At the same time, the motor on the second fixing frame 401 is controlled to drive the second fixing plate 402 to rotate, and the second fixing plate 402 drives the corresponding inner welding head 5 to align with the outer welding head 4, and then the sixth driving member 502 is controlled to push the second fixing frame 401 toward the first folding angle 6002 and the second folding angle 7002, thereby driving the second fixing frame 401 to rotate. The squeezing roller 404 moves to fit with the first folding edge 6001 and the second folding edge 7001, thereby clamping and fixing the volute at the corner by the second squeezing roller 404 and the first squeezing roller 304, so that the left side plate 6 and the right side plate 7 are tightly fitted with the volute plate 8 at this location, and then the fourth driving member 303 and the fifth driving member 403 are controlled respectively to drive the outer welding head 4 and the inner welding head 5 to move backward and forward, and perform targeted welding on the first folding angle 6002 and the second folding angle 7002 of the volute, thereby preventing the left side plate 6 and the right side plate 7 from not fitting tightly with the volute plate 8 at this location, resulting in unreliable welding at this location, thereby effectively ensuring the welding quality at the volute corner;

[0045] Then, the corresponding inner welding head 5 is driven to rotate by controlling the rotating roller 501, and the outer welding head 4 is driven to move on the arc slide rail 3 by controlling the first electric slider 201, so as to continue welding the remaining unwelded area of ​​the volute. In this process, the sixth driving member 502 is controlled to be adaptively extended and retracted, and the motor on the corresponding second fixed frame 401 is controlled to drive the inner welding head 5 to rotate. At the same time, the second driving member 202 is controlled to be adaptively extended and retracted, and the motor on the first fixed frame 301 is controlled to drive the outer welding head 4 to rotate, so that the corresponding inner welding head 5 and the outer welding head 4 are continuously adjusted in position, so that the inner welding head 5 and the outer welding head 4 move along the shape of the volute, while ensuring that the inner welding head 5 and the outer welding head 4 are always aligned;

[0046] When the outer welding head 4 moves to the top of the first folded corner 6002 and the second folded corner 7002, that is, above the air outlet of the volute, the inner welding head 5 corresponding to the rotating roller 501 cannot move to this place because the air outlet of the volute is narrow. In order to continue welding there, the motor on the second fixing frame 401 located at the air outlet of the volute is controlled to drive the second fixing plate 402 to rotate clockwise, so that the second squeezing roller 404 and other parts that were originally perpendicular to the volute tongue 8001 are rotated to fit the inner wall of the volute plate 8, and the third driving member 204 is controlled to drive the second squeezing roller 404 to move to align with the first squeezing roller 304, and then the third driving member 204 is controlled to drive the second squeezing roller 404 to move to align with the first squeezing roller 304. Component 204 drives the inner welding head 5 to move forward, controls the second driving component 202 to drive the outer welding head 4 to continue to move on the arc slide rail 3, and controls the motor on the first fixing frame 301 to drive the outer welding head 4 to rotate, so that the outer welding head 4 and the inner welding head 5 that are in contact with the inner wall of the volute plate 8 are always aligned. In this process, the upper part of the air outlet of the volute is welded by the outer welding head 4 and the inner welding head 5, thereby realizing welding of the upper side of the air outlet of the volute, thereby realizing welding of all areas of the volute and ensuring the welding quality of each part of the volute, while reducing the labor intensity of the workers and avoiding the need for the workers to move the volute left and right or adjust the tilt angle according to needs;

[0047] After the volute is welded, the air pump connected to the conveying plate 2 on the left side of the arc-shaped slide rail 3 is turned off, and the first driving member 101 on the right side of the arc-shaped slide rail 3 is controlled to drive the corresponding conveying plate 2 to move rightward and reset, thereby facilitating the removal of the volute.

[0049] On the basis of Example 1, Figure 6 and Figure 7 As shown, it also includes a clamping and positioning system, which includes an electric clamp 603 and a first moving component; the first moving component is connected to the arc slide rail 3; the first moving component is connected to two electric clamps 603; the first moving component is used to control the movement of the electric clamp 603.

[0050] The first moving component includes a third electric slider 601 and a seventh driving member 602; two third electric sliders 601 are slidably connected to the arc-shaped slide rail 3; each third electric slider 601 is fixedly connected to a seventh driving member 602, and the seventh driving member 602 is an electric push rod; the telescopic end of each seventh driving member 602 is fixedly connected to the corresponding electric clamp 603.

[0051] It also includes a second moving component and a guide extrusion block 703; the second moving component is connected to the arc slide rail 3; the second moving component is connected to the guide extrusion block 703; the second moving component is used to control the guide extrusion block 703 to move outside the volute plate 8.

[0052] A rubber layer is attached to the side of the guide extrusion block 703; when the deformation of the first fold 6001 and the second fold 7001 is corrected by the guide extrusion block 703, the rubber layer prevents the guide extrusion block 703 from causing damage to the left plate 6 and the right plate 7.

[0053] The second moving component includes a fourth electric slider 701 and a ninth driving member and an eighth driving member 702; the fourth electric slider 701 is slidably connected to the arc slide rail 3, and the ninth driving member and the eighth driving member 702 are fixedly connected to the fourth electric slider 701. The ninth driving member and the eighth driving member 702 are electric push rods; the telescopic ends of the ninth driving member and the eighth driving member 702 are fixedly connected to the guide extrusion block 703.

[0054] When the left side plate 6 and the right side plate 7 are gradually fitted together and the volute plate 8 is manually placed, the two ends of the volute plate 8 are clamped and fixed by controlling the two electric clamps 603, thereby avoiding the need for manual hand-holding of the volute plate 8. At the same time, it is convenient for manual adjustment of the position of the volute plate 8, thereby making the placement position of the volute plate 8 more accurate, which is convenient for subsequent welding work;

[0055] At the same time, in order to ensure that all parts of the volute plate 8 are located inside the first folding edge 6001 and the second folding edge 7001, and because the left side plate 6 and the right side plate 7 are easily deformed during the stacking and taking process, resulting in the first folding edge 6001 and the second folding edge 7001 being bent inward, the volute plate 8 cannot be fitted with the first folding edge 6001 and the second folding edge 7001, so before the volute is welded, when the left side plate 6 and the right side plate 7 are gradually fitted together, Figure 7 As shown, by controlling the eighth driving member 702 to push the guide extrusion block 703 toward the direction close to the volute plate 8, the guide extrusion block 703 is brought into contact with the volute plate 8 and extrudes the volute plate 8, so that after the left plate 6 and the right plate 7 are in contact with the volute plate 8, the front side of the guide extrusion block 703 will fit with the inner side of the first folding edge 6001 and the second folding edge 7001.

[0056] Then, the fourth electric slider 701 is controlled to drive the guide extrusion block 703 to move along the shape of the volute on the arc-shaped slide rail 3. At the same time, the eighth driving member 702 is controlled to adaptively extend and retract, so that the guide extrusion block 703 corrects the deformation of the first folding edge 6001 and the second folding edge 7001 when moving along the shape of the volute.

[0057] Prevent the first folded edge 6001 and the second folded edge 7001 from bending inwards and affecting the fit of the volute plate 8 therewith, thereby ensuring the welding quality of the volute;

[0058] Furthermore, since there are two welding methods for the volute plate 8 to fit the inner side of the first folding edge 6001 and the outer side of the second folding edge 7001 during the welding process of the left side plate 6 and the right side plate 7 and the volute plate 8, when the volute plate 8 needs to be fit to the outer side of the first folding edge 6001 and the second folding edge 7001 for welding, it is necessary to manually press the volute plate 8 continuously to fit the volute plate 8 to the outer side of the first folding edge 6001 and the second folding edge 7001 to prevent the volute plate 8 from not fitting to the outer side of the first folding edge 6001 and the second folding edge 7001 during the welding process. However, manually pressing the volute plate 8 continuously is labor-intensive. Therefore, before welding the volute, Figure 6 As shown, the two ends of the volute plate 8 are clamped and fixed by controlling the two electric clamps 603, and the two third electric sliders 601 are controlled to drive the corresponding seventh driving members 602 to move upward and downward respectively, and the electric clamps 603 are driven to move upward and downward by the seventh driving member 602, and then the volute plate 8 is driven by the electric clamps 603 to fit the outer sides of the first folding edge 6001 and the second folding edge 7001, so as to avoid manual continuous pressing of the volute plate 8 to reduce labor intensity. At the same time, the eighth driving member 702 is used to push the guide extrusion block 703 toward the direction close to the volute plate 8, so that the guide extrusion block 703 presses the volute plate 8 tightly against the first fold edge 6001 and the second fold edge 7001, and welds the volute along with the outer welding head 4 and the inner welding head 5. The fourth electric slider 701 drives the guide extrusion block 703 to move along the arc-shaped slide rail 3, and controls the eighth driving member 702 to perform adaptive expansion and contraction, so that the guide extrusion block 703 is always close to the volute plate 8, so that during the welding process, the volute plate 8 is always pressed tightly against the first fold edge 6001 and the second fold edge 7001, avoiding the existence of a gap between the volute plate 8 and the first fold edge 6001 and the second fold edge 7001, so as to ensure the welding effect.

[0059] Example 3

[0060] On the basis of Example 1, Figure 1 and Figure 8 As shown, a side panel mold 801 is also included; two left-right symmetrical side panel molds 801 are welded on the bracket 1, and the inner shape of the side panel mold 801 matches the outer shape of the left side panel 6 and the right side panel 7; when the left side panel 6 and the right side panel 7 are placed in contact with the conveying plate 2, the side panel mold 801 is used to limit and correct the left side panel 6 and the right side panel 7, so that the left side panel 6 and the right side panel 7 are placed at an accurate angle, effectively ensuring the accuracy of the volute.
