Description

Technical Field

[0001] The present invention relates to the field of ventilation equipment processing, and specifically to a tapping device for the production and processing of a smoke exhaust fan assembly. Background Art

[0002] A smoke exhaust fan is a core component in building fire protection and industrial ventilation systems, mainly composed of components such as fan blades, motors, and housings. Its function is to quickly discharge smoke and high-temperature gases in case of emergencies, ensuring the safety of personnel and the integrity of equipment. During production, as a key component, fan blades often need to have threaded holes processed on their surfaces through a tapping process to achieve precise assembly with other connecting parts. Since the smoke exhaust fan needs to remain stable during high-speed operation, the processing accuracy requirements for the threaded holes are extremely high.

[0003] Existing tapping devices for smoke exhaust fan blades usually include 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 on the rotating seat through a fixture, and the rotating seat rotates at a preset angle to enable the tapping tool to tap the positions to be processed on each fan blade in sequence.

[0004] However, existing tapping devices have two major defects. Firstly, they lack the function of real-time correction and locking of the fan blade position. When the rotating seat drives the fan blade to change positions for tapping, it only relies on the initial positioning, and existing devices are not equipped with an adaptive adjustment mechanism, making it difficult to compensate for dynamic errors, resulting in an error between the docking position of the fan blade and the tapping tool, causing the tapping position to shift or even the thread to be misaligned. Secondly, there is no effective support structure at the bottom of the fan blade. Fan blades are mostly thin-walled metal or plastic parts, and local stress during tapping is likely to cause deformation. In particular, the end of a long-cantilever fan blade is prone to drooping or vibrating under the action of the cutting force, resulting in the inclination of the axis of the threaded hole or uneven hole diameter, seriously affecting the tapping quality. Summary of the Invention

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a tapping device for the production and processing of a smoke exhaust fan assembly, including a device base and a tapping tool provided thereon. A rotating table driven by a motor is rotatably provided on the upper side of the device base. The present device further includes an alignment mechanism for correcting the fan blade and a stabilization mechanism for supporting the fan blade.

[0006] The alignment mechanism includes a feed frame provided on the device base through an electric push rod. Two abutting columns and two groups of clamping members are provided on the feed frame through an adjustment structure. A fine-tuning assembly capable of slightly rotating the fan blade is provided on the rotating table.

[0007] During tapping, the electric push rod drives the feed frame to drive the abutting columns to abut against the side surface of the fan blade, and at the same time, the adjustment structure adaptively drives the clamping members to clamp on the upper and lower side surfaces of the fan blade, and cooperates with the fine-tuning assembly to move the fan blade to a 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. A support plate is hinged on the upper side of the vertical section of the T-shaped plate, and a torsion spring is arranged between the T-shaped plate and the support plate.

[0009] Preferably, the adjustment structure includes a rotating disk rotatably arranged on the left side surface of the feed frame, two abutment columns are connected to the rotating disk for left and right sliding, the right part of the clamping member is a block structure and the left part is a columnar structure, and the block structure of the clamping member is slidably connected to the rotating disk.

[0010] Preferably, a synchronization plate is fixedly mounted on the right sides of the two abutment columns, a tension spring is provided between the synchronization plate and the rotating disk, and the synchronization plate is hinged to the clamping member through a connecting rod.

[0011] Preferably, a worm wheel is fixedly mounted on the outer side of the rotating disk, and a worm is rotatably arranged on the rear side of the feed frame. The worm is manually rotated to drive the rotating disk to rotate through the worm wheel, thereby adjusting the angle.

[0012] Preferably, the fine-tuning assembly includes a rotating seat rotatably arranged inside the rotating table, a pressure column is arranged on the inner side of the rotating seat for sliding up and down, a plurality of pushing blocks are arranged on the outer side of the rotating seat along its circumference for sliding radially, and an inclined surface is provided on the upper end of the pushing block close to the axis of the rotating seat.

[0013] Preferably, a notch is provided on the outer side of the rotating seat, and two return springs are arranged inside the notch of the rotating seat, and both return springs are connected to the rotating platform.

[0014] Preferably, a stop plate is provided on the lower side of the feed frame for sliding left and right, and anti-slip grooves are provided on the left side of the stop plate at equal intervals. The stop plate is locked together with the feed frame by fastening screws, and the outer side surface of the rotating table is provided with clearance grooves for inserting the stop plate at equal intervals along its circumference.

[0015] Preferably, a wedge block is provided on the upper side of the anti-rotation plate for sliding left and right, a push spring is provided between the wedge block and the feed frame, a linkage block is provided on the left side of the feed frame for sliding left and right, an adjusting screw is threadedly connected on the feed frame, and the adjusting screw is rotatably connected to the linkage block.

[0016] Preferably, a locking piece is provided on the right side of the vertical section of the T-shaped plate for sliding left and right, the diameter of the right part of the locking piece is larger than that of the left part, and a compression spring is provided between the left side of the locking piece and the T-shaped plate.

[0018] The beneficial effects of the present invention are as follows: First, the present invention uses an electric push rod to drive the feed frame to drive the abutting column to abut against the side surface of the fan blade, so that the side surface of the fan blade fits on the end surfaces of the two abutting columns. Then, in cooperation with the fine adjustment component, the fan blade is finely rotated, which can correct the offset of the fan blade in real time and lock the fan blade, effectively eliminating the dynamic error during the indexing rotation of the rotating seat and ensuring the tapping position accuracy.

[0019] Second, after the present invention uses the feed frame to correct the fan blade, it can automatically push the T-shaped plate upward, so that the support plate hinged to the upper part of the T-shaped plate automatically fits on the bottom of the fan blade, thereby forming a support for the bottom of the fan blade during the tapping process, suppressing the deformation or vibration generated by the fan blade during tapping, ensuring the tapping quality, and the adjustment structure can also adaptively drive the clamping member to clamp the upper and lower sides of the fan blade. While further ensuring the position of the fan blade, it can provide additional support for the end of the long cantilever fan blade, significantly enhancing the versatility and processing adaptability of the equipment.

[0020] Third, the present invention uses the moving feed frame to drive the anti-rotation plate to further lock the angle of the fan blade by abutting against the rotating seat, realizing the fine positioning of the fan blade before tapping. At the same time, the feed frame also locks the angle of the support plate by pushing the locking member through the linkage pipe, realizing the further stable support for the fan blade, and further improving the processing accuracy.

Detailed implementation manners

[0031] The embodiments of the present invention will be described in detail below. The embodiments described below are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention. For those not specified in the embodiments regarding specific technologies or conditions, they shall be carried out according to the technologies or conditions described in the literature in the art or according to the product specifications.

[0032] Refer to Figure 1 and Figure 2 , a tapping device for the production and processing of a smoke exhaust fan assembly, including an equipment base 1 and a tapping screw 2 arranged thereon. A rotating table 3 driven by a motor is rotatably arranged on the upper side of the equipment base 1. This equipment also includes an alignment mechanism 4 for correcting the fan blade and a stabilizing mechanism 5 for supporting the fan blade.

[0033] It should be noted that the tapping screw 2 is connected to the equipment base 1 through a structure that can be telescopic and adjustable in angle, which is commonly used in existing tapping equipment, so that the tapping screw 2 can be fed to the position of the fan blade at a preset angle for tapping operation. The motor connected to the rotating table 3 is arranged inside the equipment base 1 and is not shown in the figure. The rotation of the motor can drive the rotating table 3 to rotate synchronously, so as to change the position of the fan blade.

[0034] It should be noted that an existing fixture structure for pressing and fixing the fan blade is arranged on the equipment base 1, 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 rotatably arranged 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] During tapping, the operator first places the fan blade on the alignment 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 alignment mechanism 4 can automatically make the axis of the fan blade coincide with the axis of the pressure wheel, thereby initially locking the position of the fan blade.

[0036] Subsequently, the alignment mechanism 4 corrects the position of the fan blade so that the hole to be tapped on the fan blade is exactly aligned with the tapping screw 2. At the same time, the alignment mechanism 4 can also drive the stabilizing mechanism 5 to support the lower part of the fan blade, preventing the fan blade from deforming and causing deviation in the tapping position when the tapping screw 2 applies force to the fan blade. Then, the tapping screw 2 is moved to perform a tapping operation on one blade of the fan blade.

[0037] After completion, the motor drives the rotating table 3, so that the alignment 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 tapping screw 2. Subsequently, the alignment mechanism 4 and the stabilizing mechanism 5 are used to correct and support the fan blade again, and so on, to complete the tapping operation on all blades of the fan blade.

[0038] Refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown in, the alignment mechanism 4 includes a feed frame 41 arranged on the equipment base 1 through an electric push rod 46. Two abutting columns 43 and two groups of clamping members 44 are arranged on the feed frame 41 through an adjustment structure 42. A fine adjustment assembly 45 capable of slightly rotating the fan blade is arranged on the rotating table 3. During tapping, the electric push rod 46 drives the feed frame 41 to push the abutting column 43 to abut against the side surface of the fan blade, and at the same time, the adjustment structure 42 adaptively drives the clamping members 44 to clamp on the upper and lower side surfaces of the fan blade, and cooperates with the fine adjustment assembly 45 to move the fan blade to a specified position.

[0039] Refer to Figure 2 、 Figure 3 and Figure 4 As shown in, the fine adjustment assembly 45 includes a rotating seat 451 rotatably arranged inside the rotating table 3. A pressing column 452 is slidably arranged up and down inside the rotating seat 451. A plurality of pushing blocks 453 sliding radially along the circumferential direction are arranged on the outer side of the rotating seat 451. An inclined surface is opened at one end of the upper end of the pushing block 453 close to the axis of the rotating seat 451.

[0040] When tapping the fan blade is required, 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 pressing wheel presses on the upper part of the fan blade, the pressing wheel synchronously pushes the pressing column 452 downward, so that the lower end surface of the pressing column 452 contacts the inclined surface of the pushing block 453, so that the pressing column 452 synchronously pushes the pushing block 453 outward.

[0041] When the pressing wheel fits on the upper part of the fan blade, the pressing column 452 pushes the pushing block 453 to abut against the inner side surface of the fan blade, so as to automatically adjust the fan blade to be coaxially arranged with the rotating seat 451. In the present invention, the operator manually pulls out the pressing column 452 and replaces the pressing column 452 with different lengths, so as to adapt to fan blades with different inner diameters and different heights.

[0042] Refer to Figure 1 、 Figure 3 and Figure 6 As shown in, the adjusting structure 42 includes a rotating disk 421 rotatably arranged on the left side surface of the feeding frame 41. Both of the two abutting columns 43 are slidably connected to the rotating disk 421 in the left-right direction. The right part of the clamping member 44 has a block structure and the left part has a columnar structure. A synchronous plate 422 is fixedly installed on the right sides of the two abutting columns 43 together. The block structure of the clamping member 44 slides on the rotating disk 421 along the direction perpendicular to the length direction of the synchronous plate 422. A tension spring is arranged 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 synchronous plate 422, and each group is composed of two clamping members 44 corresponding to the ends of the synchronous plate 422.

[0044] In the initial state, the tension spring pulls the synchronous plate 422 to the left relative to the rotating disk 421 through its own elastic force. The synchronous plate 422 drives the abutting columns 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] Refer to Figure 3 、 Figure 5 and Figure 7 As shown in, a worm gear 424 is fixedly installed on the outer side of the rotating disk 421. A worm 425 is rotatably arranged at the rear side of the feeding frame 41. Manually rotating the worm 425 drives the rotating disk 421 to rotate through the worm gear 424, so as to adjust the angle. A notch is formed on the outer side of the rotating seat 451. Two return springs are arranged inside the notch of the rotating seat 451, and both of the two 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 table 3 through their own elastic forces, and due to the compression amounts of the two return springs, the rotating seat 451 has a space for slightly rotating left and right relative to the rotating table 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 blades on the fan blade, so that the worm 425 drives the rotating disk 421 to rotate through the worm gear 424. The rotating disk 421 drives the two abutting columns 43 to rotate synchronously, so that the two abutting columns 43 can correspond to the end positions 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 part of the fan blade. When the left end surfaces of the two abutment columns 43 are both in contact with the fan blade, a blade on the right part of the fan blade is arranged horizontally to the left and right, and the hole to be tapped on a blade on the right part 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 and is in a left-right horizontal arrangement in the initial state, 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 also 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 by sliding 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 also Figure 6 and Figure 7 A stop plate 411 is provided on the lower side of the feed frame 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 frame 41 by fastening screws. The outer side surface of the rotating table 3 is provided with makeshift grooves for inserting the stop plate 411 at equal intervals along its circumference.

[0052] See also 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 part of the fan blade, and the reaction force of the fan blade on the support plate 52 causes the support plate 52 to rotate to match the inclination angle of the blade, so that the blade is supported by the upward thrust of the support plate 52 on the middle part of the blade.

[0054] Subsequently, continue to move the feed frame 41 to the left, so that the reaction force of the fan blade against the abutting column 43 pushes the abutting column 43 to the right. The abutting column 43 drives two groups of clamping members 44 to approach each other through the synchronous plate 422 and the connecting rod 423, so that the two groups of clamping members 44 clamp on the blade. While the position of the blade can be further locked, the lower group of clamping members 44 can also support the end of the blade, thus adapting to the support of the long-cantilever fan blade, significantly enhancing the versatility and processing adaptability of the equipment.

[0055] The operator pre-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 through the fastening screw, so that when the two groups of clamping members 44 clamp on the fan blade, the left side surface of the anti-rotation plate 411 can pass through the corresponding relief groove and abut against the outer side surface 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 rotates the adjusting screw 532 in advance, so that the adjusting screw 532 drives the linkage block 531 to adjust the position left and right, so that when the two groups of clamping members 44 clamp on the fan blade, the left side surface of the linkage block 531 abuts against the right side surface 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] Refer to Figure 7 and Figure 8 , a locking member 511 is slidably arranged left and right on the right side of the vertical section of the T-shaped plate 51. The diameter of the right part of the locking member 511 is larger than that of the left part. A compression spring is arranged between the left side of the locking member 511 and the T-shaped plate 51. A telescopic square rod 54 is slidably arranged left and right on the upper side of the linkage block 531. A linkage tube 541 is fixedly installed on the upper side of the telescopic square rod 54. A support rod 542 slidably connected to the linkage tube 541 is fixedly installed on the right side of the locking member 511.

[0058] The operator pre-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 member 511 to the right through its own elastic force, so that the left side surface of the large-diameter part of the right part of the locking member 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 member 511 to move synchronously, and the locking member 511 drives the linkage tube 541 to move synchronously through the support rod 542.

[0059] When the two sets of clamping members 44 clamp on the fan blade, 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 surface of the large-diameter part on the right of the locking member 511 abuts against the support plate 52, thereby locking the rotation angle between the support plate 52 and the T-shaped plate 51, and further increasing the stability when the support plate 52 supports the fan blade.

[0060] Subsequently, by moving the tap 2 downward, threading processing is performed on the holes on the fan blade. Then, the telescopic section of the electric push rod 46 is contracted to drive the feed frame 41 to move to the initial position. After that, the rotating table 3 drives the rotating seat 451 to rotate, and the rotating seat 451 drives the next blade to be processed on the fan blade to rotate to the lower part of the tap 2. Subsequently, the feed frame 41 is moved to the right again, and the above steps are repeated, so as to perform threading processing on all the blades of the fan blade.

[0061] Refer to Figures 1 to 8 , when the present invention performs threading processing on the fan blade, the following steps are further included: The first step is that the operator manually places the fan blade on the upper part of the rotating seat 451, and the moving pressure wheel presses on the upper part of the fan blade, so that the pressure wheel pushes the pushing block 453 through the pressing column 452 to abut against the inner side surface of the fan blade, thereby automatically adjusting the fan blade to be coaxially arranged with the rotating seat 451.

[0062] The second step is that the operator manually rotates the worm 425 according to the inclination angle of the blades on the fan blade, so that the worm 425 drives the rotating disk 421 to rotate through the worm wheel 424, and the rotating disk 421 drives the two abutting columns 43 to rotate synchronously, so that the two abutting columns 43 can correspond to the end positions of the fan blade.

[0063] The third step is to extend the telescopic section of the electric push rod 46. When the left end surfaces of the two abutting columns 43 are both attached to the fan blade, one blade on the right of the fan blade is pushed to be horizontally arranged left and right, and the hole to be threaded on one blade on the right of the fan blade is located at the coaxial position below the tap 2.

[0064] The fourth step is that the feed frame 41 drives the wedge block 53 to push the T-shaped plate 51 upward through the pushing spring, and the T-shaped plate 51 drives the support plate 52 to rotate to the inclination angle adapted to the blade, so as to support the blade.

[0065] The fifth step is to continue moving the feed frame 41 to the left, so that the reaction force of the fan blade on the abutting column 43 pushes the abutting column 43 to the right, and the abutting column 43 drives the two sets of clamping members 44 to clamp on the blade, which can further lock the position of the blade and support the end of the blade.

[0066] In the sixth step, the left side surface of the rotation stop plate 411 abuts against the outer side surface 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.

[0067] In the seventh step, the left side surface of the linkage block 531 abuts against the right side surface 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.

[0068] In the eighth step, the linkage block 531 pushes the locking member 511 through the telescopic square rod 54 and the linkage pipe 541, so that the left side surface of the large-diameter part on the right of the locking member 511 abuts against the support plate 52, thereby locking the rotation angle between the support plate 52 and the T-shaped plate 51, and further increasing the stability of the support plate 52 when supporting the fan blade.

[0069] In the ninth step, move the tapping tool 2 downward to perform tapping on the holes on the fan blade. Then, contract the telescopic section of the electric push rod 46 to drive the feed frame 41 to move to the initial position. After that, drive the rotating seat 451 to rotate through the rotating table 3. The rotating seat 451 drives the next blade to be processed on the fan blade to rotate to the lower part of the tapping tool 2. Then, move the feed frame 41 to the right again and repeat the above steps to perform tapping on all the blades of the fan blade.

[0070] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention, and still be covered by the protection scope of the present invention.
