Description

Technical Field

[0001] The present invention relates to the technical field of wind wheel processing, and more specifically, to a wind wheel processing device for a fan coil unit. Background Art

[0002] The fan coil impeller, referred to as the impeller, is a rotating component installed inside the fan coil unit. When the fan coil unit is working, the impeller rotates under the drive of the motor, generating air flow, sucking in the indoor air and exchanging heat through the coil unit, and then sending out the conditioned air, thereby achieving indoor temperature regulation and air circulation.

[0003] The fan coil impeller is usually composed of three parts: a lower ring, fins and an upper ring, and the lower ring, fins and upper ring are welded together. Since the rotation of the fins is required to realize air circulation, the fins are set at an angle, but the inclination angles of the fins inside different fan coil impellers are different. Therefore, when welding the fins, it is necessary to arrange several fins at a certain inclination angle so that their bottoms are evenly welded to the lower ring, and their tops are evenly welded to the upper ring. Since it is necessary to arrange several fins at the same inclination angle before welding, this increases the difficulty of welding. If the angle is measured and marked and then the fins are welded one by one, the efficiency is low. If several fins are limited by a pre-made angle plug-in template, although several fins can be well arranged at the same inclination angle, the pre-made angle plug-in template can only weld a specific angle and a specific fin thickness, which will result in a narrow scope of application.

[0004] At the same time, when the fins are being plugged in, the fins may not be properly plugged in, causing the fins to be offset from the upper ring or the lower ring, resulting in the welded fan coil impeller becoming a defective product.

[0005] Based on this, the present invention designs a fan coil unit wind wheel processing device. Summary of the invention

[0039] The present invention can place the wind wheel lower ring 7 inside the lower ring placement cavity 102 by setting the lower ring placement cavity 102. The setting of the lower ring placement cavity 102 can limit the wind wheel lower ring 7 to prevent it from moving. Through the setting of the screw rod 104 and the lifting execution motor 105, the fin adjustment mechanism 3 can be lifted and lowered as a whole. The setting of the cross plate 107, the square hole 108, the positioning bolt 109 and the guide hole 110 can be used to adjust the lifting of the fin extrusion mechanism 4.

[0041] The present invention provides an upper ring bearing mechanism 2, which can, on the one hand, position and install the wind rotor upper ring 8, and on the other hand, make the wind rotor upper ring 8 contact with the top of the wind rotor fin 6 to prepare for subsequent welding. The specific operation method is: place the wind rotor upper ring 8 into the positioning groove inside the upper ring bearing frame 210, and fix the wind rotor upper ring 8 through two electrically controlled suction cups 213, and then start the control switch of the rotating execution motor 211, and the upper ring bearing frame 210 can be rotated 180 degrees by rotating the execution motor 211, so that the wind rotor upper ring 8 faces downward, and then the rotating plate 206 is rotated 180 degrees, and then the limiting bolt 209 is screwed so that the top end of the limiting bolt 209 is inserted into the corresponding limiting hole 207.

[0042] Reference Figure 3 , Figure 6 and Figure 7 As shown, the fin adjustment mechanism 3 includes a mounting ring 301 located just above the lower ring placement cavity 102 and coaxial with the lower ring placement cavity 102, a lifting slider 302 adapted to the screw rod 104 is fixedly mounted on the outer wall of the mounting ring 301, and a plurality of annular evenly distributed fixing components 303 are fixedly mounted on the inner wall of the mounting ring 301, and a rotating component 304 is rotatably connected to the side of the fixing component 303 away from the mounting ring 301. Through the cooperation of the lifting slider 302 and the screw rod 104, the overall lifting and lowering of the fin adjustment mechanism 3 can be realized.

[0043] See also Figure 7 and Figure 8 The fixing assembly 303 includes a connecting column 3032 fixed on the inner wall of the mounting ring 301, and a mounting bracket 3031 is fixedly installed at one end of the connecting column 3032 away from the mounting ring 301, and arc-shaped fixing plates 3033 are fixedly installed on the inner bottom surface and the inner top surface of the mounting bracket 3031, and the two arc-shaped fixing plates 3033 are arranged opposite to each other, and a fixing support block 3034 is fixedly installed on the inner bottom surface of the mounting bracket 3031 and located on the outer side of the arc-shaped fixing plate 3033, and a guide groove 3035 is opened on the fixing support block 3034; by setting the fixing assembly 303, it can play a role in bearing the rotating assembly 304, so that the rotating assembly 304 can rotate thereon.

[0044] See also Figure 7 and Fig. 9The rotating component 304 includes a mounting column 3041, a vertical hole 3042 is formed on the mounting column 3041, and a limit plate 3043 for clamping and limiting the wind wheel fin 6 is provided on the two inner walls opposite to the vertical hole 3042, and the limit plate 3043 is connected to the inner wall of the vertical hole 3042 through a torsion spring, and the upper and lower end surfaces of the mounting column 3041 are provided with an arc-shaped sliding groove 3044 that slides with the arc-shaped fixing plate 3033, and a semi-toothed ring 2 3045 is fixedly installed on the outer wall of the mounting column 3041; by setting the rotating component 304, the wind wheel fin 6 clamped inside it can rotate with it, thereby realizing the adjustment of the angle of the wind wheel fin 6; by setting two relatively arranged limit plates 3043, the wind wheel fin 6 can be clamped and limited.

[0045] See also Figure 7 , Figure 8 and Fig. 9 A rotating guide ring 305 is connected to the inside of several guide grooves 3035 for common rotation, and an inner tooth ring 306 meshing with several semi-tooth rings 3045 distributed in a ring shape is fixedly installed on the inner wall of the rotating guide ring 305. A gear 307 is connected to the inside of one of the mounting brackets 3031 for common rotation, and a driving motor 308 is installed on the top of the mounting bracket 3031 through a motor seat.

[0046] The present invention starts the control switch of the drive motor 308, and the drive motor 308 can drive the gear 307 to rotate. Since the gear 307 is meshed with the semi-toothed ring 1 309, the rotation of the gear 307 can drive the semi-toothed ring 1 309 to rotate. Due to the coordinated use of the arc-shaped fixed plate 3033 inside the fixed component 303 and the arc-shaped slide groove 3044 inside the rotating component 304, the rotating component 304 can rotate as a whole while the semi-toothed ring 1 309 rotates. At this time, the semi-toothed ring inside the rotating component 304 is The second half-toothed ring 3045 will rotate. Since the half-toothed ring 3045 and the inner toothed ring 306 are meshed and connected, the half-toothed ring 3045 can drive the inner toothed ring 306 to rotate. The rotation of the inner toothed ring 306 can drive the remaining half-toothed rings 3045 to rotate together, thereby driving the remaining rotating components 304 to rotate together. Since the wind wheel fins 6 are clamped and limited inside the rotating component 304, the rotation of several rotating components 304 can drive the wind wheel fins 6 to rotate together, thereby achieving a unified adjustment of the angles of several wind wheel fins 6.

[0047] The present invention provides a fin adjustment mechanism 3, which can, firstly, quickly and conveniently adjust the angles of a plurality of wind wheel fins 6 in a unified manner, thereby greatly improving the processing efficiency; secondly, ensure the accuracy of adjusting the inclination angle of the wind wheel fins 6, thereby avoiding inconsistent inclination angles of the wind wheel fins 6, which would result in an unsightly welded fan coil wind wheel; and thirdly, can adjust the inclination angle of the wind wheel fins 6 over a larger range, thereby greatly improving the scope of application of the present invention.

[0048] Reference Figure 3 , Fig.10 and Fig.11 As shown, the fin extrusion mechanism 4 includes a square tube 408 that vertically passes through the square hole 108, a door-shaped frame 407 is fixedly installed on the bottom end of the square tube 408, a receiving ring 401 is fixedly installed on the bottom of the door-shaped frame 407, a plurality of square through-columns 402 that are evenly distributed in an annular shape slide through the inside of the receiving ring 401, an extrusion plate 403 corresponding to the wind wheel fin 6 is fixedly installed on the outer end of the square through-column 402, an end plate 404 is fixedly installed on the inner end of the square through-column 402, a return spring 405 is sleeved on the outer side of the square through-column 402 and located between the inner side wall of the receiving ring 401 and the end plate 404, a convex column 406 is fixedly installed on the side surface of the end plate 404 away from the square through-column 402, an anti-fall frame 409 is fixedly sleeved on the outer side surface of the top end of the square tube 408, A positioning hole 410 is provided at the top of one side of the square tube 408 close to the positioning bolt 109, and one end of the positioning bolt 109 located inside the square hole 108 is inserted into the corresponding positioning hole 410. An adjusting stud 411 is penetrated through the internal thread of the square tube 408 and located in the middle position of the portal frame 407. An inverted cone 412 corresponding to a plurality of bosses 406 is fixedly installed at the bottom end of the adjusting stud 411. One end of the boss 406 away from the end plate 404 rests on the side wall of the smooth inverted cone 412. An adjusting column 413 is fixedly installed at the top of the adjusting stud 411. The adjusting column 413 passes through the square tube 408 and extends to the top of the square tube 408. A guide rod 414 parallel to the square tube 408 and penetrating the guide hole 110 is fixedly installed on the upper surface of the portal frame 407.

[0049] The present invention rotates the adjusting column 413, and the adjusting column 413 will drive the adjusting stud 411 and the inverted table 412 to rotate. Since the adjusting stud 411 and the door frame 407 are threadedly connected, the rotation of the adjusting stud 411 can cause the inverted table 412 to rotate and move downward at the same time. The downward movement of the inverted table 412 can squeeze the protruding column 406, so that a plurality of annular protruding columns 406 move from the inside to the outside, thereby driving the extrusion plate 403 to move from the inside to the outside through the end plate 404 and the square through column 402. At the same time, the reset spring 405 will shrink and shorten. The extrusion plate 403 moves from the inside to the outside and squeezes the wind wheel fins 6, so that a plurality of wind wheel fins 6 are installed in place. Thereafter, the adjusting column 413 is rotated in the opposite direction to move the inverted table 412 upward. Due to the elastic force of the reset spring 405, the extrusion plate 403 will move inward and no longer squeeze the wind wheel fins 6.

[0050] The present invention provides a fin squeezing mechanism 4, which can squeeze the wind wheel fin 6 inserted into the vertical hole 3042 between the two limit plates 3043 before adjusting its inclination angle, so that a plurality of annularly distributed wind wheel fins 6 can be installed in place, thereby making the installation position of the wind wheel fin 6 more precise and achieving a better subsequent welding effect.

[0051] Reference Fig.12 As shown, the welding mechanism 5 includes two symmetrically arranged end blocks 501, the end block 501 located at the bottom is fixedly installed above the supporting platform 101, and two parallel vertical columns 502 are fixedly installed between the two end blocks 501. A lifting slide 503 is slidably sleeved on the outer sides of the two vertical columns 502, and a supporting ring 504 is fixedly installed on one side surface of the lifting slide 503.

[0052] The present invention can perform the final welding work on the fixed wind wheel fins 6, the wind wheel lower ring 7 and the wind wheel upper ring 8 by providing the welding mechanism 5.

[0053] Welding process: when it is necessary to evenly weld a number of wind wheel fins 6 on the wind wheel lower ring 7, the staff will first place the wind wheel lower ring 7 to be welded inside the lower ring placement cavity 102, and then evenly insert the wind wheel fins 6 from the inside to the outside between the two limit plates 3043 located inside the vertical hole 3042 and make the bottom of the wind wheel fin 6 contact with the upper surface of the wind wheel lower ring 7, and the wind wheel fin 6 can be limited by the limit plate 3043. After the installation of the wind wheel fins 6 is completed, the adjusting column 413 is rotated, and the adjusting column 413 will drive the adjusting stud 411 and the inverted round table 412 to rotate. The screw thread connection is adopted, so the rotation of the adjusting stud 411 can make the inverted truncated cone 412 rotate and move downward at the same time, and the downward movement of the inverted truncated cone 412 can squeeze the protruding column 406, so that a plurality of protruding columns 406 distributed in an annular shape move from the inside to the outside, thereby driving the squeezing plate 403 to move from the inside to the outside through the end plate 404 and the square through column 402, and at the same time the return spring 405 will shrink and shorten, and the squeezing plate 403 will move from the inside to the outside to squeeze the wind wheel fins 6, so that a plurality of wind wheel fins 6 are installed in place, and then the adjusting column 413 is rotated in the opposite direction to make the inverted truncated cone 412 move upward, and due to the elastic force of the return spring 405, the squeezing plate 403 will move inward and no longer press the wind wheel The fins 6 are extruded, and then the inclination angles of several wind wheel fins 6 are adjusted according to the required welding angles, and the control switch of the drive motor 308 is started. The drive motor 308 can drive the gear 307 to rotate. Since the gear 307 is meshed and connected with the semi-toothed ring 1 309, the rotation of the gear 307 can drive the semi-toothed ring 1 309 to rotate. Due to the coordinated use of the arc-shaped fixed plate 3033 inside the fixed component 303 and the arc-shaped slide groove 3044 inside the rotating component 304, the rotating component 304 can rotate as a whole while the semi-toothed ring 1 309 rotates. At this time, the semi-toothed ring 2 3045 inside the rotating component 304 will rotate. The second ring 3045 is meshed with the inner gear ring 306, so the second half-gear ring 3045 can drive the inner gear ring 306 to rotate, and the rotation of the inner gear ring 306 can drive the remaining second half-gear rings 3045 to rotate together, thereby driving the remaining rotating components 304 to rotate together. Since the wind wheel fins 6 are clamped and limited inside the rotating components 304, the rotation of several rotating components 304 can drive the wind wheel fins 6 to rotate together, thereby realizing the unified adjustment of the angles of several wind wheel fins 6. After adjusting the angles of the wind wheel fins 6, by moving the carrying ring 504, the several lower welding nozzles 505 are aligned with the connection between the wind wheel fins 6 and the wind wheel lower ring 7 for welding;

[0054] When it is necessary to weld several wind wheel fins 6 evenly on the wind wheel upper ring 8, the positioning bolt 109 is loosened at this time to disengage the inner end of the positioning bolt 109 from the inside of the positioning hole 410, and then the fin squeezing mechanism 4 is moved vertically upward as a whole to make the fin squeezing mechanism 4 be located above the wind wheel fins 6, and the lifting execution motor 105 is started, and the lifting execution motor 105 drives the screw rod 104 to rotate, and drives the lifting slider 302 to move upward, thereby driving the entire fin adjustment mechanism 3 to move vertically upward, so that the fin adjustment mechanism 3 is located above the wind wheel fins 6, and then the wind wheel upper ring 8 is placed in the positioning groove inside the upper ring carrier 210, and the wind wheel can be adjusted by two electrically controlled suction cups 213. The upper ring 8 is fixed, and then the control switch of the rotating execution motor 211 is started. By rotating the execution motor 211, the upper ring carrier 210 can be rotated 180 degrees, so that the wind wheel upper ring 8 faces downward, and then the rotating plate 206 is rotated 180 degrees, and then the limit bolt 209 is screwed so that the top of the limit bolt 209 is inserted into the corresponding limit hole 207. At this time, the wind wheel upper ring 8 is directly above a number of wind wheel fins 6, and then the hydraulic rod 203 is started to make the lower surface of the wind wheel upper ring 8 contact the top of the wind wheel fin 6, and then the bearing ring 504 is moved to align the several upper welding nozzles 506 with the connection between the wind wheel fin 6 and the wind wheel upper ring 8 for welding.
