Description

Technical Field

[0001] The present invention relates to the technical field of the production of exhaust fan impellers, and in particular to an impeller processing platform for an exhaust fan. Background Art

[0002] An exhaust fan is an important device used in a fire exhaust system. It is a driven fluid machine, mainly composed of an impeller, a casing, a motor, bearings, a transmission device, a shock absorption device, and a control system, etc. Its impeller is composed of components such as a wheel disc and blades, and the blades need to be welded to the wheel disc.

[0003] In the existing impeller processing platform, the installation position and installation angle of each blade are often confirmed by manually scribing on the wheel disc, and the cutting position that each blade needs to be cut is confirmed by scribing on the blade. There are large errors, low accuracy, and it is necessary to hold the blade by hand and spot-weld it to the wheel disc, with a very high labor intensity and low work efficiency, which is not conducive to the mass production of impellers. Summary of the Invention

[0004] This application discloses an impeller processing platform for an exhaust fan to solve the problems of large errors in manual scribing, high labor intensity, and low work efficiency in the prior art.

[0005] To solve the above problems, the present invention adopts the following technical solutions: An impeller processing platform for an exhaust fan, comprising: An angle adjustment mechanism, on which a wheel disc is detachably connected, and the angle adjustment mechanism is used to adjust the angle of the wheel disc; A blade positioning mechanism, which is located on one side of the angle adjustment mechanism, and the blade positioning mechanism is used to position the installation position and installation angle of the blade on the wheel disc; A scribing mechanism, which is located on one side of the angle adjustment mechanism, and the scribing mechanism is used to scribe the cutting position of the blade; Wherein, the rotation axis of the angle adjustment mechanism does not intersect with the horizontal axes of the blade positioning mechanism and the scribing mechanism.

[0006] The technical solutions adopted by the present invention can achieve the following beneficial effects: In the present invention, the roulette is mounted on the angle adjustment mechanism. By adjusting the distance between the blade positioning mechanism and the angle adjustment mechanism, the blade is placed on the blade positioning mechanism. The blade positioning mechanism positions the installation position and installation angle of the blade on the roulette. There is no need for manual scribing on the roulette, and then the blade is spot-welded to the roulette. After welding one blade, the angle of the roulette is adjusted through the angle adjustment mechanism so that the blades can be evenly distributed on the roulette. After the impeller welding is completed, according to the design requirements of impellers with different diameters, the distance between the scribing mechanism and the angle adjustment mechanism is adjusted, and the cutting position of the blade is scribed through the scribing mechanism, which is convenient for subsequent cutting of the blade. Through the setting that the rotation axis of the angle adjustment mechanism does not intersect with the horizontal axes of the blade positioning mechanism and the scribing mechanism, the blade positioning mechanism and the scribing mechanism can achieve multi-angle fine adjustment relative to the angle adjustment mechanism to meet different impeller design and performance requirements; through the mutual cooperation of the angle adjustment mechanism, the blade positioning mechanism and the scribing mechanism, the present invention avoids the problem of large errors caused by manual scribing, has high accuracy, realizes semi-automatic spot-welding work of the blade, reduces the labor intensity, improves the work efficiency, and is conducive to the batch production of impellers.

Detailed implementation manners

[0010] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0011] The terms "first", "second", "third", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order different from those illustrated or described herein, and the objects distinguished by "first", "second", "third", etc. are generally of the same type, and do not limit the number of objects. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0012] During the processing of the impeller, in the existing impeller processing platform, since the installation lines corresponding to the installation positions and installation angles of each blade are often manually marked on the wheel disc, and then the blades are spot-welded to the wheel disc by manually holding the blades, and manual correction of each blade is required. Then, according to the design requirements of impellers with different diameters, in order to control the diameter of the impeller, it is necessary to manually mark on the processed blades the cutting lines for each blade to be cut. Therefore, there are large errors in the manual marking in this processing method, which cannot ensure the accuracy of the installation positions and installation angles of each blade, nor can it ensure the consistency of the cutting lines, and the overall labor intensity is very high, the work efficiency is low, which is not conducive to the mass production of impellers.

[0013] The following combines the attached Figures 1 to 10 to elaborate in detail on an impeller processing platform provided by the present application through specific embodiments and their application scenarios.

The blade positioning mechanism 200 is used to position the installation position and installation angle of the blade 20 on the wheel disc 10, eliminating the problem of large errors caused by manual marking on the wheel disc 10; The marking mechanism 300 is located on one side of the angle adjustment mechanism 100. The marking mechanism 300 is used to mark the cutting position of the blade 20 to facilitate subsequent cutting of the blade 20; Among them, the rotation axis of the angle adjustment mechanism 100 does not intersect with the horizontal axes of the blade positioning mechanism 200 and the marking mechanism 300, enabling the blade positioning mechanism 200 and the marking mechanism 300 to achieve multi-angle fine adjustment relative to the angle adjustment mechanism 100 to meet different impeller design and performance requirements.

The top of the base 111 is provided with a cylindrical boss, and an indicating needle 1111 is installed on one side of the boss. The rotating table 113 is rotatably connected to the boss on the top of the base 111. The rotating table 113 is also cylindrical. The diameter of the rotating table 113 is the same as that of the boss. The lower part of the rotating table 113 is provided with scale lines 1131 that cooperate with the indicating needle 1111. There are 360 scale lines 1131, corresponding to 360° in one circle. Through the cooperation of the scale lines 1131 and the indicating needle 1111, it is convenient to accurately observe the rotation angle of the wheel disc 10, and it is convenient to weld the blades 20 evenly on the wheel disc 10.

At this time, in order to prevent the wheel disc 10 from rotating due to external factors, by rotating the rotating rod 1141, the connecting rod 1142 is driven, and then the stopper 1143 is driven to stand up, so that the stopper 1143 blocks the teeth of the worm wheel 1122 and prevents the worm wheel 1122 from rotating. In this embodiment, when the worm wheel 1122 rotates, the rotating rod 1141 is horizontally arranged. When the worm wheel 1122 needs to be blocked, the rotating rod 1141 rotates clockwise to stand up the stopper 1143.

When the bolts are loosened, the mounting plate 122 can rotate relative to the support rod 123; the middle of the wheel disc 10 is recessed, and the middle of the wheel disc 10 can be detachably connected to the mounting plate 122 by bolts; the axes of the wheel disc 10, the mounting plate 122, the support rod 123, the chuck 121, the rotating table 113, and the connecting shaft 1123 coincide.

[0021] Refer to Figure 6 and Figure 7 In this embodiment, the blade positioning mechanism 200 includes a lifting assembly 210, a horizontal moving assembly 220, and a positioning plate 230; The horizontal moving assembly 220 is connected to the lifting assembly 210, and the positioning plate 230 is detachably connected to the horizontal moving assembly 220. The lifting assembly 210 is used to lift the horizontal moving assembly 220 to adjust the height of the positioning plate 230; The horizontal movement component 220 is used to drive the positioning plate 230 to move horizontally, so as to adjust the distance between the positioning plate 230 and the wheel disc 10; The positioning plate 230 is used to position the installation position and installation angle of the blade 20 on the wheel disc 10.

[0022] Refer to Figure 6 and Figure 7 In this embodiment, the lifting component 210 includes a first sleeve 211 and a first sliding rod 212; The first sleeve 211 is sleeved outside the first sliding rod 212. The first sliding rod 212 is slidably matched with the first sleeve 211. The top of the first sliding rod 212 is connected to the horizontal movement component 220.

[0023] Specifically, the first sleeve 211 is vertically installed on the top of the workbench 30. The top and bottom of the first sleeve 211 are penetrated. The first sliding rod 212 is vertically slidably arranged in the first sleeve 211, and the first sliding rod 212 penetrates through the workbench 30 and extends into the interior of the workbench 30. A limiting plate 213 is installed at one end of the first sliding rod 212 located inside the workbench 30 to prevent the first sliding rod 212 from detaching from the first sleeve 211. The first sliding rod 212 is slidably matched with the workbench 30; Bolts are rotatably installed on both sides of the first sleeve 211, and the position of the first sliding rod 212 can be fixed by the bolts; In this embodiment, the first sliding rod 212 can also rotate in the first sleeve 211 to adjust the position of the positioning plate 230, facilitating the cooperation between the positioning plate 230 and the wheel disc 10.

[0024] Refer to Figure 6 and Figure 7 In this embodiment, the horizontal movement component 220 includes a second sleeve 221 and a second sliding rod 222; The second sleeve 221 is connected to the top of the first sliding rod 212. The second sleeve 221 is sleeved outside the second sliding rod 222. The second sliding rod 222 is slidably matched with the second sleeve 221.

[0025] Specifically, the second sleeve 221 is horizontally installed on the top of the first sliding rod 212. The two sides of the second sleeve 221 penetrate, and bolts are rotatably installed on its adjacent two sides to fix the position of the second sliding rod 222 through the bolts; the second sliding rod 222 is horizontally slidably arranged in the second sleeve 221. The second sliding rod 222 can be L-shaped. The length of the horizontal part of the second sliding rod 222 is greater than the distance between the support rod 123 and the first sleeve 211. A support plate 223 is installed on the vertical part of the second sliding rod 222. A positioning plate 230 is detachably installed on the top of the support plate 223. Positioning holes are provided on the support plate 223. A positioning pin is installed on the top of the positioning plate 230. Through the cooperation of the positioning holes and the positioning pins, the positioning plate 230 is detachably installed on the support plate 223. The number of the positioning holes and the positioning pins can be 2-4 respectively; the upper part of the positioning plate 230 is inclined, and the corresponding positioning plate 230 can be replaced according to the inclination angle of the blade 20; in this embodiment, the second sliding rod 222 is horizontally arranged, and the horizontal axis of the second sliding rod 222 is perpendicular to but does not intersect the rotation axis of the wheel disc 10. The positioning plate 230 is inclined and installed on the support plate 223, and the side surface of the positioning plate 230 is parallel to the plane corresponding to the tangent of the wheel disc 10. Through this setting, when the blade 20 is placed on the positioning plate 230 and contacts the side surface of the wheel disc 10, the installation position and installation angle of the blade 20 can be directly positioned. And the non-intersecting setting can achieve flexible fine adjustment at multiple angles, which helps to accurately control the installation angle of the blade to meet different impeller design and performance requirements. It can also prevent the second sliding rod 222 from interfering with surrounding objects, leaving enough space for the installation and operation of the blade 20, enabling the welding work to proceed smoothly, and also providing a more open working space for the operator, facilitating the operator to perform welding operations, and improving the welding quality and work efficiency.

[0026] Referring to Figures 8 to 10 , in this embodiment, the scribing mechanism 300 includes a sliding component 310 and a scribing component 320; The scribing component 320 is connected to the sliding component 310. The sliding component 310 is used to drive the scribing component 320 to move to adjust the distance between the scribing component 320 and the blade 20; The scribing component 320 is used to scribe the cutting position of the blade 20.

[0027] In this embodiment, the sliding component 310 includes a guide rail 311 and a slider 312; The slider 312 is slidably connected to the guide rail 311, and the scribing component 320 is connected to the slider 312.

[0028] Specifically, the guide rail 311 is horizontally installed on the top of the workbench 30, and the guide rail 311 and the first sleeve 211 are respectively located on both sides of one end of the top of the workbench 30. The length direction of the guide rail 311 is perpendicular to but does not intersect with the axis of the support rod 123; the slider 312 is slidably engaged with the guide rail 311, and a bolt is rotatably installed on the top of the slider 312. By means of the bolt, the slider 312 can be fixed on the guide rail 311 to prevent the slider 312 from continuing to slide on the guide rail 311.

[0029] Referring Figures 8 to 10 , in this embodiment, the scribing assembly 320 includes a column 321 and a scribing part 322; The column 321 is connected to the slider 312, and the scribing part 322 is slidably connected to the column 321. The scribing part 322 is used to scribe the cutting position of the blade 20.

[0030] Specifically, the column 321 is a square column, and the column 321 is vertically installed on the top of the slider 312; The scribing part 322 includes a sliding sleeve 3221 slidably installed on the column 321. A square hole matching the column 321 is formed in the sliding sleeve 3221. A bolt is rotatably installed on one side of the sliding sleeve 3221. By means of the bolt, the sliding sleeve 3221 can be fixed on the column 321 to fix the height position of the sliding sleeve 3221 on the column 321; on the side of the sliding sleeve 3221 close to the support rod 123, a mounting rod 3222 is horizontally installed. The mounting rod 3222 is arranged parallel to the length direction of the guide rail 311. A mounting groove 3223 is formed at one end of the mounting rod 3222 away from the sliding sleeve 3221. A scribing pen 3224 is installed in the mounting groove 3223, and a bolt extending to the outside of the mounting rod 3222 is rotatably installed on one side of the mounting groove 3223. The position of the scribing pen 3224 is fixed by means of the bolt.

[0031] By setting that the horizontal axis of the mounting rod 3222 does not intersect with the rotation axis of the wheel disc 10, during the rotation of the impeller, sufficient movement space is provided for the mounting rod 3222 and the scribing pen 3224, enabling the operator to more conveniently approach the blade 20 for scribing operations. Especially when the space around the impeller is relatively compact, it can effectively avoid collisions and interferences, improve the convenience and safety of the operation, and is beneficial to improving the work efficiency and the accuracy of scribing, reducing the occurrence of situations where the size of the blade 20 does not meet the requirements due to cutting line deviation. Moreover, by adjusting the horizontal position of the mounting rod 3222, the scribing requirements for the blades of impellers with different diameters can be adapted, improving the versatility and adaptability of the scribing mechanism 300.

[0032] Working principle: When in use, first install the roulette 10 on the mounting plate 122, install the positioning plate 230 corresponding to the blade 20 on the support plate 223, adjust the height of the positioning plate 230 through the first sliding rod 212, and adjust the horizontal distance between the positioning plate 230 and the roulette 10 through the second sliding rod 222. After the adjustment is completed, make the indicating needle 1111 point to the 0 scale. Then place the blade on the positioning plate 230, and perform spot welding on the side contact part between the blade 20 and the roulette 10. After welding one blade 20, release the locking of the worm gear 1122 by the stop block 1143. By rotating the handwheel 1124, the worm 1121 is driven to rotate. The worm 1121 drives the worm gear 1122 to rotate, thereby driving the connecting shaft 1123 to rotate, and further driving the rotating table 113 to rotate, thus driving the chuck 121, the support rod 123 and the mounting plate 122 to rotate, and further driving the roulette 10 to rotate. When the rotating table 113 rotates to the welding angle where the blade 20 needs to be welded to the roulette 10, it can be observed through the scale line 1131 and the indicating needle 1111. At this time, in order to prevent the roulette 10 from rotating due to external factors, rotate the rotating rod 1141, thereby driving the connecting rod 1142, and further driving the stop block 1143 to stand up, so that the stop block 1143 blocks the teeth of the worm gear 1122 to prevent the worm gear 1122 from rotating. Place the new blade 20 on the positioning plate 230, and spot weld the blade 20 to the roulette 10. Repeat the above steps until all the blades 20 of the impeller are welded to the roulette 10; After welding is completed, according to the design requirements of impellers with different diameters, adjust the horizontal distance between the marking pen 3224 and the blade 20 of the impeller through the sliding fit between the slider 312 and the guide rail 311, and adjust the height of the marking pen 3224 through the sliding sleeve 3221, so that the marking pen 3224 is located above the blade 20. After adjusting the distance to be cut, loosen the bolt between the mounting plate 122 and the support rod 123, so that the mounting plate 122 can rotate relative to the support rod 123. When the impeller rotates, when the blade 20 passes directly below the marking pen 3224, move the sliding sleeve 3221 downward to make the marking pen 3224 move downward, and the marking pen 3224 draws a cutting line on the blade 20. Although the blade 20 is inclined, the distance between the marking pen 3224 and the axis of the impeller remains unchanged. Therefore, when the blade 20 passes the marking pen 3224, the marking pen 3224 only needs to move vertically downward to draw an arc-shaped cutting line on the blade 20. When the next blade 20 passes the marking pen 3224, move the marking pen 3224 above the blade 20 in advance and perform marking again. Repeat the above steps until all the blades 20 of the impeller are marked. Subsequently, only need to cut along the cutting line to control the diameter size of the impeller.

[0033] The present invention avoids the problem of large errors caused by manual scribing, has high accuracy, realizes semi-automation of the spot welding operation of the blade 20, reduces the labor intensity, improves the work efficiency, and is conducive to the mass production of the impeller.
