Description
Technical Field
[0001] This utility model relates to the field of tapping equipment, and in particular to a tapping equipment for a fan end cover. Background Technology
[0002] In the production and processing of wind turbines, tapping the end caps is a crucial step. The quality of the tapping directly affects the assembly accuracy and performance of the end caps. Currently, traditional wind turbine end cap tapping equipment has some shortcomings: it is difficult to accurately position the tapping location when tapping the end caps, which can easily lead to deviations in the tapping position and affect product quality; when multiple holes on the same horizontal line need to be tapped, the position of the end caps needs to be adjusted multiple times, which is cumbersome and reduces tapping efficiency.
[0003] Therefore, it is necessary to invent a tapping device for the end cap of a fan to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a tapping device for a fan end cover to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a tapping device for a fan end cover, comprising a tapping table and a fan end cover, wherein a tapping assembly is provided on the top of the tapping table, a placement block corresponding to the fan end cover is provided on the top of the tapping table, and a translation assembly is provided on the bottom of the tapping table.
[0006] The translation component includes a mounting box, in which a threaded rod is rotatably connected. A threaded block is threadedly connected to the outer wall of the threaded rod. A connecting rod is fixedly connected to the left side of the threaded block. A strip-shaped opening corresponding to the connecting rod is opened on the side wall of the mounting box. A mounting block is fixedly connected to the top of the connecting rod. A T-shaped block is fixedly connected to the bottom of the mounting block. A T-shaped opening corresponding to the T-shaped block is opened on the top of the tapping table. The mounting block is fixedly installed to the bottom of the T-shaped block by bolts.
[0007] Preferably, support legs are fixedly connected to the four corners of the bottom of the tapping table, and stabilizing plates are provided at the bottom of the multiple support legs. The provision of support legs and stabilizing plates increases the contact area between the tapping table and the ground, improves the overall stability of the equipment, and avoids the equipment from shaking during the tapping process, which would affect the tapping accuracy.
[0008] Preferably, the tapping assembly includes an L-shaped bracket fixedly connected to the top of the tapping table, a cylinder fixedly connected to the top of the L-shaped bracket, a rectangular frame fixedly connected to the output end of the cylinder, a motor fixedly installed inside the rectangular frame, and a tapping head fixedly connected to the output end of the motor.
[0009] Preferably, the top of the rectangular frame is fixedly connected to two limiting rods, and the bottom of the L-shaped bracket is provided with limiting holes corresponding to the limiting rods. The cooperation between the limiting rods and the limiting holes plays a limiting role in the movement of the rectangular frame, ensuring that the tapping head moves in the vertical direction and further improving the tapping accuracy.
[0010] Preferably, an infrared positioner is provided on the right side of the motor. The infrared positioner is installed in a rectangular frame. The infrared positioner can accurately locate the tapping position before tapping, which makes it convenient for operators to adjust the position of the fan end cover and ensure that the tapping position is accurate.
[0011] Preferably, a mounting plate is fixedly connected to the top of the mounting box. The mounting plate is fixedly installed to the top of the tapping table by bolts. The mounting plate is fixedly installed to the tapping table by bolts, which facilitates the installation and disassembly of the translation component and makes it convenient for the translation component to be maintained and repaired in the future.
[0012] Preferably, the front end of the threaded rod passes through the mounting box and is fixedly connected to a turntable. The turntable makes it convenient for the operator to rotate the threaded rod, thereby driving the placement block to move. The operation is simple and convenient, improving work efficiency.
[0013] Preferably, a guide rod is fixedly connected inside the mounting box, and a guide cylinder is fixedly connected to the top of the threaded block, with the guide cylinder and the guide rod being slidably connected.
[0014] The technical effects and advantages of this utility model are as follows: By setting a translation component, multiple holes on the same horizontal line can be tapped. The setting of the thread rod can accurately adjust the position between the hole and the tapping head, making the tapping position more accurate. In addition, the thread rod is not directly set at the bottom of the tapping head, so the debris generated during tapping will not affect the thread rod, thus extending the service life of the equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] This utility model provides, for example Figure 1-5 The tapping device for a fan end cover shown includes a tapping table 1 and a fan end cover 2. A tapping assembly 3 is provided on the top of the tapping table 1. A placement block 4 corresponding to the fan end cover 2 is provided on the top of the tapping table 1. The fan end cover 2 is generally circular, and the top of the placement block 4 is arc-shaped. The shape of the placement block 4 matches the fan end cover 2, so that the fan end cover 2 can be clamped on the placement block 4. A translation assembly 5 is provided at the bottom of the tapping table 1.
[0023] The translation component 5 includes a mounting box 51, with a threaded rod 52 rotatably connected inside the mounting box 51. A threaded block 53 is threadedly connected to the outer wall of the threaded rod 52. A connecting rod 54 is fixedly connected to the left side of the threaded block 53. A slot corresponding to the connecting rod 54 is opened on the side wall of the mounting box 51. A mounting block 55 is fixedly connected to the top of the connecting rod 54. A T-shaped block 56 is fixedly connected to the bottom of the placement block 4. A T-shaped opening corresponding to the T-shaped block 56 is opened on the top of the tapping table 1. The mounting block 55 is fixedly installed to the bottom of the T-shaped block 56 by bolts. The translation component 5 can tap multiple holes on the same horizontal line. The threaded rod 52 can precisely adjust the position between the hole and the tapping head 35, making the tapping position more accurate. Furthermore, the threaded rod 52 is not directly set at the bottom of the tapping head 35, so the debris generated during tapping will not affect the threaded rod 52.
[0024] Support legs 6 are fixedly connected to the four corners of the bottom of the tapping table 1, and stabilizing plates 7 are provided at the bottom of the multiple support legs 6.
[0025] The tapping assembly 3 includes an L-shaped bracket 31 fixedly connected to the top of the tapping table 1, a cylinder 32 fixedly connected to the top of the L-shaped bracket 31, a rectangular frame 33 fixedly connected to the output end of the cylinder 32, a motor 34 fixedly installed inside the rectangular frame 33, and a tapping head 35 fixedly connected to the output end of the motor 34. The setting of the cylinder 32 allows the tapping head 35 to move vertically downward, ensuring the stability of tapping. When the cylinder 32 is working, it can drive the rectangular frame 33, the motor 34 and the tapping head 35 to move up and down. When the motor 34 is working, it drives the tapping head 35 to rotate to perform tapping.
[0026] Two limiting rods 8 are fixedly connected to the top of the rectangular frame 33. The bottom of the L-shaped bracket 31 is provided with limiting holes corresponding to the limiting rods 8. When the rectangular frame 33 moves up and down, the limiting rods 8 slide in the limiting holes, which plays a limiting and guiding role, ensuring that the tapping head 35 moves vertically.
[0027] An infrared positioner 9 is provided on the right side of the motor 34. The infrared positioner 9 is installed inside the rectangular frame 33. The ray position of the infrared positioner 9 corresponds to the bottom tapping position of the tapping head 35, which can be used to position the tapping position before tapping.
[0028] The top of the mounting box 51 is fixedly connected to the mounting plate 10, which is fixedly installed to the top of the tapping table 1 by bolts.
[0029] The front end of the threaded rod 52 passes through the mounting box 51 and is fixedly connected to the turntable 11.
[0030] A guide rod 12 is fixedly connected inside the mounting box 51, and a guide cylinder 13 is fixedly connected to the top of the threaded block 53. The guide cylinder 13 and the guide rod 12 are slidably connected.
[0031] The working principle of this utility model is as follows: First, the fan end cover 2 is placed on the placement block 4, and it is fixed in place on the arc-shaped placement block 4. Then, the first tapping position is positioned by the ray emitted by the infrared positioner 9. If the position does not correspond, the turntable 11 is rotated, which drives the threaded rod 52 to rotate. This causes the threaded block 53 to move the placement block 4 through the connecting rod 54, the mounting block 55, and the T-shaped block 56 until the hole on the fan end cover 2 is aligned with the ray of the infrared positioner 9, thus completing the positioning. Next, the motor 34 is started, which drives the tapping head 35 to rotate. Then, the cylinder 32 is started, which pushes the rectangular frame 33, the motor 34, and the tapping head 35 downward. The tapping head 35 is aligned with the hole on the fan end cover 2. The tapping operation is performed on the holes. During the tapping process, the limit rod 8 slides in the limit hole to ensure that the tapping head 35 moves vertically. After the first hole is tapped, the cylinder 32 drives the tapping head 35 to return to its original position. Then, the turntable 11 is rotated, and the fan end cover 2 is moved by the translation component 5 so that the next hole to be tapped is aligned with the ray of the infrared positioner 9. The above tapping steps are repeated to complete the tapping operation of multiple holes on the same horizontal line. The debris generated during the tapping process will fall on the tapping table 1. Since the thread rod 52 is set in the mounting box 51 and is not located directly below the tapping head 35, the debris will not affect the thread rod 52, ensuring the normal operation and adjustment accuracy of the translation component 5.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
