Description

Technical Field

[0001] The invention relates to the field of ventilation equipment processing, in particular to a tapping device for producing and processing smoke exhaust fan components. Background Art

[0002] Smoke exhaust fans are core components in building fire protection and industrial ventilation systems. They are mainly composed of fan blades, motors, casings and other parts. Their function is to quickly exhaust smoke and high-temperature gases in emergency situations to ensure personnel safety and equipment integrity. In production, fan blades, as key components, often need to be processed with threaded holes on their surfaces through a tapping process to achieve precise assembly of the fan blades and other connectors. Since smoke exhaust fans need to remain stable under high-speed operation, extremely high processing accuracy requirements are placed on the threaded holes.

[0003] Existing smoke exhaust fan blade tapping equipment usually includes an operating table for fixing the fan blades, a rotating seat driven by a motor, and a tapping device controlled by an electric push rod. During operation, the fan blades are fixed to the rotating seat by a clamp, and the rotating seat rotates according to a preset angle, so that the tap taps the to-be-processed position of each fan blade in turn.

[0004] However, existing tapping equipment has two major defects. First, it lacks the real-time correction and locking function of the fan blade position. When the rotating seat drives the fan blade to change position for tapping, it only relies on the initial positioning, and the existing equipment is not equipped with an adaptive adjustment mechanism, which makes it difficult to compensate for dynamic errors, resulting in an error between the fan blade stop position and the tap, causing the tapping position to shift or even the thread to be misplaced. Second, there is a lack of effective support structure at the bottom of the fan blade. The fan blades are mostly thin-walled metal or plastic parts. Local force during tapping can easily cause deformation, especially the end of the long cantilever fan blade is prone to drooping or vibrating under the action of cutting force, causing the threaded hole axis to tilt or the aperture to be uneven, seriously affecting the tapping quality. Summary of the Invention

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a tapping device for the production and processing of smoke exhaust fan components, including an equipment base and a tap arranged thereon, a rotating table driven by a motor is rotatably arranged on the upper side of the equipment base, and the equipment also includes a positioning mechanism for correcting the fan blades and a stabilizing mechanism for supporting the fan blades.

[0007] During tapping, the electric push rod pushes the feed frame to drive the abutment column to rest against the side of the fan blade. At the same time, the adjustment structure adaptively drives the clamping parts to clamp on the upper and lower sides of the fan blade, and cooperates with the fine-tuning component to move the fan blade to the specified position.

[0008] The stabilizing mechanism comprises a T-shaped plate which is arranged on the equipment seat and slides up and down through a guide column.

[0031] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0032] See Figure 1 and Figure 2 A tapping device for the production and processing of smoke exhaust fan components includes an equipment base 1 and a tap 2 arranged thereon. A rotating table 3 driven by a motor is rotatably arranged on the upper side of the equipment base 1. The equipment also includes a positioning mechanism 4 for correcting the fan blades and a stabilizing mechanism 5 for supporting the fan blades.

[0033] It should be noted that the tap 2 is connected to the equipment base 1 through a retractable and angle-adjustable structure commonly used on existing tapping equipment, so that the tap 2 can be fed to the position of the fan blade at a preset angle for tapping operations. The motor connected to the rotary table 3 is arranged inside the equipment base 1, not shown in the figure. The rotation of the motor can drive the rotary table 3 to rotate synchronously, thereby replacing the fan blades.

[0034] It should be noted that the equipment base 1 is provided with an existing clamp structure for pressing and fixing the fan blades, which mainly includes an electric cylinder fixedly installed on the rear side of the equipment base 1, a lever hinged on the upper side of the equipment base 1, a pressure wheel is rotatably provided on the lower side of the front end of the lever, and the rear end of the lever is hinged to the telescopic section of the electric cylinder.

[0035] When tapping, the operator first places the fan blade on the positioning mechanism 4, and then extends the telescopic section of the electric cylinder, so that the electric cylinder drives the pressure wheel to press on the upper part of the fan blade through the lever, and the positioning mechanism 4 can automatically make the axis of the fan blade coincide with the axis of the pressure wheel, thereby preliminarily locking the position of the fan blade.

[0036] Then, the position of the fan blade is corrected by the alignment mechanism 4 so that the hole on the fan blade that needs to be tapped corresponds to the tap 2. At the same time, the alignment mechanism 4 can also drive the stabilization mechanism 5 to support the lower part of the fan blade to prevent the fan blade from deforming and causing deviation in the tapping position when the tap 2 applies force to the fan blade. Then, the tap 2 is moved to perform the tapping operation on a blade on the fan blade.

[0037] After completion, the motor drives the rotating table 3, so that the positioning mechanism 4 drives the fan blade to rotate a preset angle, so that the next blade of the fan blade corresponds to the lower part of the tap 2, and then the fan blade is corrected and supported again by the positioning mechanism 4 and the stabilizing mechanism 5, and so on, to complete the tapping operation of all blades on the fan blade.

[0038] See Figure 1 、 Figure 2 、 Figure 6 and Figure 7 The positioning mechanism 4 includes a feed rack 41 arranged on the equipment base 1 through an electric push rod 46. Two abutment columns 43 and two sets of clamping members 44 are provided on the feed rack 41 through an adjustment structure 42. A fine-tuning component 45 that can slightly rotate the fan blade is provided on the rotary table 3. When tapping, the electric push rod 46 drives the abutment column 43 to abut against the side of the fan blade by pushing the feed rack 41. At the same time, the adjustment structure 42 adaptively drives the clamping member 44 to clamp on the upper and lower sides of the fan blade, and cooperates with the fine-tuning component 45 to move the fan blade to the specified position.

[0039] See Figure 2 、 Figure 3 and Figure 4 The fine-tuning component 45 includes a rotating base 451 rotatably arranged inside the rotating table 3, a pressing column 452 is arranged on the inner side of the rotating base 451 for sliding up and down, and a plurality of pushing blocks 453 are arranged on the outer side of the rotating base 451 along its circumference and sliding along its radial direction. The upper end of the pushing block 453 is provided with an inclined surface at one end close to the axis of the rotating base 451.

[0040] When the fan blade needs to be tapped, the operator manually places the fan blade on the upper part of the rotating seat 451, and makes the pushing block 453 and the pressing column 452 both located inside the fan blade. When the pressure wheel presses on the upper part of the fan blade, the pressure wheel simultaneously pushes the pressing column 452 downward, so that the lower end face of the pressing column 452 contacts the inclined surface of the pushing block 453, thereby making the pressing column 452 push the pushing block 453 outward synchronously.

[0041] When the pressure wheel is attached to the upper part of the fan blade, the pressure column 452 pushes the pushing block 453 against the inner side of the fan blade, thereby automatically adjusting the fan blade to be arranged coaxially with the rotating seat 451. The present invention allows the operator to manually pull out the pressure column 452 and replace the pressure column 452 with a different length, thereby adapting to fan blades with different inner diameters and different heights.

[0042] See Figure 1 、 Figure 3 and Figure 6 The adjusting structure 42 includes a rotating disk 421 rotatably arranged on the left side of the feed frame 41, and the two abutment columns 43 are connected to the rotating disk 421 for sliding left and right. The right part of the clamping member 44 is a block structure and the left part is a columnar structure. A synchronous plate 422 is fixedly installed on the right side of the two abutment columns 43. The block structure of the clamping member 44 slides on the rotating disk 421 in a direction perpendicular to the length direction of the synchronous plate 422. A tension spring is provided between the synchronous plate 422 and the rotating disk 421. The synchronous plate 422 is hinged to the clamping member 44 through a connecting rod 423.

[0043] In this embodiment, the two groups of clamping members 44 are symmetrically arranged relative to the synchronizing plate 422 , and each group is composed of two clamping members 44 corresponding to the ends of the synchronizing plate 422 .

[0044] In the initial state, the tension spring pulls the synchronous plate 422 leftward relative to the rotating disk 421 through its own elastic force, and the synchronous plate 422 drives the abutment column 43 to move synchronously, and the synchronous plate 422 pushes the two groups of clamping members 44 away from each other through the connecting rod 423.

[0045] See Figure 3 、 Figure 5 and Figure 7 A worm gear 424 is fixedly installed on the outside of the rotating disk 421, and a worm 425 is rotatably provided on the rear side of the feed frame 41. The worm 425 is manually rotated to drive the rotating disk 421 to rotate through the worm gear 424, thereby adjusting the angle. A slot is provided on the outside of the rotating seat 451, and two return springs are provided inside the slot of the rotating seat 451. Both return springs are connected to the rotating table 3.

[0046] In the initial state, the two return springs push the rotating seat 451 to move synchronously with the rotating platform 3 through their own elastic force, and the compression of the two return springs allows the rotating seat 451 to have space to rotate slightly left and right relative to the rotating platform 3.

[0047] After the fan blade is locked on the rotating seat 451, the operator manually rotates the worm 425 according to the inclination angle of the blade on the fan blade, so that the worm 425 drives the rotating disk 421 to rotate through the worm gear 424, and the rotating disk 421 drives the two abutment columns 43 to rotate synchronously, so that the two abutment columns 43 can correspond to the end position of the fan blade.

[0048] Then, the telescopic section of the electric push rod 46 is extended, and the electric push rod 46 drives the feed frame 41 to move to the left, and the feed frame 41 drives the abutment column 43 to abut against the right end surface of a blade on the right side of the fan blade. When the left end surfaces of the two abutment columns 43 are both in contact with the fan blade, the blade on the right side of the fan blade is arranged horizontally to the left and right, and the hole to be tapped on the blade on the right side of the fan blade is located at the coaxial position of the lower part of the tap 2.

[0049] It should be noted that when the rotating table 3 drives a blade on the right side of the fan blade through the rotating seat 451 in the initial state, that is, when the left end faces of the two abutment columns 43 are both in contact with the fan blade, the fan blade will not be pushed to rotate. On the contrary, the abutment column 43 will drive the rotating seat 451 to rotate by pushing the fan blade, and compress one of the return springs, and the elastic force of the tension spring is greater than the elastic force of the return spring.

[0050] See Figure 1 、 Figure 6 and Figure 7 The stabilizing mechanism 5 includes a T-shaped plate 51 which is set on the equipment seat 1 and slides up and down through a guide column. A support plate 52 is hinged on the upper side of the vertical section of the T-shaped plate 51. A torsion spring is set between the T-shaped plate 51 and the support plate 52, which is not shown in the figure.

[0051] See Figure 6 and Figure 7 A stop plate 411 is provided on the lower side of the feed rack 41 for sliding left and right. Anti-slip grooves are provided on the left side of the stop plate 411 at equal intervals. The stop plate 411 is locked together with the feed rack 41 by fastening screws. The outer side surface of the rotating table 3 is provided with clearance grooves for inserting the stop plate 411 at equal intervals along its circumference.

[0052] See Figure 3 、 Figure 6 、 Figure 7 and Figure 8 A wedge block 53 is provided on the upper side of the anti-rotation plate 411 for sliding left and right, a push spring is provided between the wedge block 53 and the feed rack 41, a linkage block 531 is provided on the left side of the feed rack 41 for sliding left and right, an adjusting screw 532 is threadedly connected on the feed rack 41, and the adjusting screw 532 is rotatably connected to the linkage block 531.

[0053] When the feed rack 41 moves to the left, the feed rack 41 drives the wedge block 53 to move synchronously through the push spring, so that the wedge surface of the wedge block 53 contacts the horizontal section of the T-plate 51, so that the wedge block 53 pushes the T-plate 51 upward, and the T-plate 51 drives the support plate 52 to move synchronously until it contacts the lower side surface of the blade on the right side of the fan blade. The reaction force of the fan blade on the support plate 52 causes the support plate 52 to rotate to an inclination angle that adapts to the blade, thereby supporting the blade through the upward thrust of the support plate 52 on the middle part of the blade.

[0054] Then continue to move the feed rack 41 to the left, so that the reaction force of the fan blade on the abutment column 43 pushes the abutment column 43 to the right, and the abutment column 43 drives the two groups of clamping parts 44 to approach each other through the synchronization plate 422 and the connecting rod 423, so that the two groups of clamping parts 44 are clamped on the blade, which can further lock the position of the blade. At the same time, the lower group of clamping parts 44 can also support the end of the blade, thereby adapting to the support of long cantilever fan blades, significantly enhancing the versatility and processing adaptability of the equipment.

[0055] The operator adjusts the position of the anti-rotation plate 411 left and right in advance, and locks the anti-rotation plate 411 on the feed frame 41 by tightening the screws, so that when the two sets of clamping parts 44 are clamped on the fan blades, the left side of the anti-rotation plate 411 can pass through the corresponding position of the clearance groove and rest on the outer side of the rotating seat 451, thereby locking the rotation angle of the rotating seat 451. Through further locking, the stability of the fan blade during tapping is further increased.

[0056] The operator manually turns the adjusting screw 532 in advance so that the adjusting screw 532 drives the linkage block 531 to adjust its position left and right, so that when the two sets of clamping members 44 are clamped on the fan blades, the left side of the linkage block 531 abuts against the right side of the wedge block 53. Through the abutment of the linkage block 531, the elastic connection between the wedge block 53 and the feed frame 41 is transformed into a rigid connection, thereby stabilizing the supporting force of the support plate 52 on the middle part of the blade.

[0057] See Figure 7 and Figure 8 A locking piece 511 is provided on the right side of the vertical section of the T-shaped plate 51 for sliding left and right. The diameter of the right part of the locking piece 511 is larger than that of the left part. A compression spring is provided between the left side of the locking piece 511 and the T-shaped plate 51. A telescopic square rod 54 is provided on the upper side of the linkage block 531 for sliding left and right. A linkage tube 541 is fixedly installed on the upper side of the telescopic square rod 54. A support rod 542 that is slidably connected to the linkage tube 541 is fixedly installed on the right side of the locking piece 511.

[0058] The operator slides the telescopic square rod 54 left and right on the linkage block 531 in advance, and locks the telescopic square rod 54 and the linkage block 531 together with screws. In the initial state, the compression spring pushes the locking piece 511 to the right by its own elastic force, so that the left side of the large diameter part of the right part of the locking piece 511 does not contact the support plate 52. When the T-shaped plate 51 drives the support plate 52 to move upward, the T-shaped plate 51 drives the locking piece 511 to move synchronously, and the locking piece 511 drives the linkage tube 541 to move synchronously through the support rod 542.

[0059] When the two sets of clamping members 44 are clamped on the fan blades, the linkage block 531 pushes the locking member 511 through the telescopic square rod 54 and the linkage tube 541, so that the left side of the large diameter part of the right part of the locking member 511 rests on the support plate 52, thereby locking the rotation angle between the support plate 52 and the T-shaped plate 51, further increasing the stability of the support plate 52 when supporting the fan blades.

[0060] Then, the tap 2 is moved downward to tap the holes on the fan blades, and then the telescopic section of the electric push rod 46 is retracted to drive the feed rack 41 to move to the initial position, and then the rotating seat 451 is driven to rotate by the rotating table 3, and the rotating seat 451 drives the next blade to be processed of the fan blade to rotate to the lower part of the tap 2, and then the feed rack 41 is moved to the right again, and the above steps are repeated to tap all the blades of the fan blade.

[0061] See Figures 1 to 8 The present invention further comprises the following steps when tapping the fan blades:

[0062] In the first step, the operator manually places the fan blade on the upper part of the rotating seat 451, and moves the pressure wheel to press on the upper part of the fan blade, so that the pressure wheel pushes the pushing block 453 against the inner side of the fan blade through the pressing column 452, thereby automatically adjusting the fan blade to be coaxial with the rotating seat 451.

[0063] In the second step, the operator manually rotates the worm 425 according to the inclination angle of the blade on the fan blade, so that the worm 425 drives the rotating disk 421 to rotate through the worm gear 424, and the rotating disk 421 drives the two abutment columns 43 to rotate synchronously, so that the two abutment columns 43 can correspond to the end position of the fan blade.

[0064] The third step is to extend the telescopic section of the electric push rod 46 so that the left end faces of the two abutment columns 43 are both in contact with the fan blades, pushing a blade on the right side of the fan blades to be arranged horizontally left and right, and making the hole to be tapped on a blade on the right side of the fan blades located at the coaxial position of the lower part of the tap 2.

[0065] In the fourth step, the feed frame 41 drives the wedge block 53 to push the T-shaped plate 51 upward through the push spring, and the T-shaped plate 51 drives the support plate 52 to rotate to an inclination angle that matches the blade, thereby supporting the blade.

[0066] The fifth step is to continue to move the feed rack 41 to the left, so that the reaction force of the fan blade on the abutment column 43 pushes the abutment column 43 to the right. The abutment column 43 drives the two sets of clamps 44 to clamp on the blade, which can further lock the position of the blade and support the end of the blade.

[0067] In the sixth step, the left side of the anti-rotation plate 411 abuts against the outer side of the rotating seat 451, thereby locking the rotation angle of the rotating seat 451. Through further locking, the stability of the fan blade during tapping is further increased.

[0068] In the seventh step, the left side of the linkage block 531 abuts against the right side of the wedge block 53. Through the abutment of the linkage block 531, the elastic connection between the wedge block 53 and the feed rack 41 is transformed into a rigid connection, thereby stabilizing the supporting force of the support plate 52 on the middle part of the blade.

[0069] In the eighth step, the linkage block 531 pushes the locking piece 511 through the telescopic square rod 54 and the linkage tube 541, so that the left side of the large diameter part of the right part of the locking piece 511 rests on the support plate 52, thereby locking the rotation angle between the support plate 52 and the T-shaped plate 51, further increasing the stability of the support plate 52 when supporting the fan blades.

[0070] In the ninth step, the tap 2 is moved downward to tap the holes on the fan blades, and then the telescopic section of the electric push rod 46 is retracted to drive the feed rack 41 to move to the initial position, and then the rotating seat 451 is driven to rotate by the rotating table 3. The rotating seat 451 drives the next blade to be processed of the fan blade to the lower part of the tap 2, and then the feed rack 41 is moved to the right again, and the above steps are repeated to tap all the blades of the fan blade.

[0071] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered by the scope of protection of the present invention.
