[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figures 1-9 The present invention provides a technical solution: a metal plate tapping processing equipment, including a support frame 1, a movable frame 6 movably mounted on the support frame 1, and a moving component 5 for moving the movable frame 6 up and down on the support frame 1; the tapping processing equipment also includes a fixed sleeve, and a tapping head 21 is used to be installed in a fixed column 2; specifically, the fixed column 2 has a groove structure adapted to the tapping head 21 inside, and a part of the tapping head 21 is fixed in the groove structure; the fixed column 2 is composed of two column structures, and the top end of the fixed column 2 is rotatably mounted on the movable frame 6 through a bearing, and a driving component 61 for driving the fixed column 2 to rotate is provided on the movable frame 6; a support platform 11 is provided on the support frame 1, and the support platform 11 is located below the tapping head 21.

[0034] The drive assembly 61 includes a drive motor, the output end of which is fixedly connected to the top of the fixed post 2, and the output end of the drive motor is coaxial with the fixed post 2. By working the drive motor, the fixed post 2 can be rotated, thereby driving the tapping head 21 to rotate.

[0035] A limiting sleeve 3 is provided on the outside of the fixed column 2. Both the limiting sleeve 3 and the fixed column 2 are vertically arranged. The limiting sleeve 3 and the fixed column 2 are coaxial. The fixed column 2 is movably connected to the limiting sleeve 3 through two sealed bearings. The two sealed bearings are respectively close to the upper and lower ends of the limiting sleeve 3. An elastic sleeve 8 is provided on the outside of the limiting sleeve 3. The elastic sleeve 8 can be made of silicone or other materials. A detachable sleeve 4 is provided on the outside of the limiting sleeve 3. The outer ring surface of the elastic sleeve 8 is fixed on the inner ring surface of the detachable sleeve 4. That is, the elastic sleeve 8 is located between the detachable sleeve 4 and the limiting sleeve 3. At the same time, the elastic sleeve 8 fits against the outer wall of the limiting sleeve 3.

[0036] Three spiral grooves 31 are provided on the limiting sleeve 3. The three spiral grooves 31 do not intersect each other and have the same cross-sectional structure. In addition, airflow can be introduced into each spiral groove 31 through an air guide assembly 7. Each spiral groove 31 extends to the bottom end of the limiting sleeve 3 but does not extend to the top end of the limiting sleeve 3. Furthermore, the upper part of the limiting sleeve 3 passes through the support frame 1, and the upper part of the limiting sleeve 3 does not contact the support frame 1.

[0037] The elastic sleeve 8 is formed by splicing two arc-shaped sleeves 81, which are fixed to the detachable sleeve 4. Each arc-shaped sleeve 81 is provided with a spiral protrusion 821 and a spiral protrusion 831. The spiral protrusions 821 on the two arc-shaped sleeves 81 are spliced ​​to form a spiral protrusion 82, and the spiral protrusions 831 on the two arc-shaped sleeves 81 are spliced ​​to form a spiral protrusion 83. The spiral protrusions 821 and 831 on the arc-shaped sleeves 81 can be integrally formed with the arc-shaped sleeves 81, and the entire elastic sleeve 8 is elastic.

[0038] The spiral protrusion 82 fits into one of the spiral grooves 31, specifically, one side of the spiral protrusion 82 fits into the upper edge of the spiral groove 31; while the spiral protrusion 82 fits into another spiral groove 31, specifically, one side of the spiral protrusion 83 fits into the lower edge of the spiral groove 31; by the spiral protrusion 82 fitting into one of the spiral grooves 31, and by the spiral protrusion 83 fitting into the other spiral groove 31, it is convenient for the elastic sleeve 8 to fit into the limiting sleeve 3.

[0039] The detachable sleeve 4 is composed of three circumferentially distributed arc-shaped plates 41 spliced ​​together. The number of arc-shaped plates 41 is the same as the number of spiral grooves 31, and the three arc-shaped plates 41 are evenly distributed circumferentially along the axis of the limiting sleeve 3. Two adjacent arc-shaped plates 41 are in contact with each other. Each arc-shaped plate 41 has an arc-shaped protrusion 42 at both the upper and lower ends. Each arc-shaped protrusion 42 is connected to the moving frame 6 by screws. That is, the detachable sleeve 4 is composed of three parts, and each part is connected to the moving frame 6 by screws, that is, each part is detachable.

[0040] Since the detachable sleeve 4 is composed of multiple parts, and each part is detachable; and the elastic sleeve 8 is formed by splicing two arc-shaped sleeves 81, it is convenient for the elastic sleeve 8 to cooperate with the limiting sleeve 3; when the elastic sleeve 8 cooperates with the limiting sleeve 3, except for the part of the arc-shaped sleeve 81 corresponding to the three spiral grooves 31 (this part includes the spiral protrusion 1 821 and the spiral protrusion 2 831), the other parts of the arc-shaped sleeve 81 fit against the outer wall of the limiting sleeve 3.

[0041] The air guiding assembly 7 includes three nozzles 74, each penetrating the middle of one of three arc-shaped plates 41. The three nozzles 74 have different heights and are fixed to their respective arc-shaped plates 41. Each nozzle 74 corresponds to one of three spiral grooves 31 and also penetrates an elastic sleeve 8. Specifically, the elastic sleeve 8 has three through holes through which the three nozzles 74 pass. The air guiding assembly 7 also includes a guide pipe 71 mounted on the support frame 1. Each nozzle 74 is connected to the guide pipe 71 via a flexible air hose 73, which is bent rather than straightened. The guide pipe 71 has an air inlet 72 for connecting to an external pressurized air source, thereby introducing pressurized airflow into the guide pipe 71, which is then guided through the flexible air hose 73 to the nozzle, and further into the three spiral grooves 31. Additionally, as... Figure 8 As shown, from a top-down view, the three air nozzles 74 are evenly distributed around the outside of the limiting sleeve 3.

[0042] A guide bucket 62 is also fixedly installed on the movable frame 6. The guide bucket 62 is located outside the tapping head 21, that is, the tapping head 21 passes through the guide bucket 62. The guide bucket 62 is located below the elastic sleeve 8. The guide bucket 62 is coaxial with the limiting cylinder. There is a gap between the bottom end of the tapping head 21 and the guide bucket 62.

[0043] In this embodiment, by placing the metal plate on the support platform 11, the metal plate can be fixed or adjusted using the existing clamping device, which is prior art and will not be described in detail here; by driving the fixed column 2 to rotate through the second drive motor 611, the tapping head 21 can be rotated, and at the same time, the moving component 5 drives the moving frame 6 to descend, so that the tapping operation can be performed on the metal plate.

[0044] In this embodiment, a spiral groove 31 is provided on the limiting sleeve 3 to facilitate the engagement of the elastic sleeve 8 with the limiting sleeve 3. Simultaneously, during the tapping process, airflow is introduced into the guide pipe 71 through an external pressure air source, and further introduced into the three air nozzles 74 through the air guide hose 73. The three air nozzles 74 then spray pressurized airflow into the three spiral grooves 31 respectively. Since the three air nozzles 74 are located at the center of the three arc-shaped plates 41, and the three arc-shaped plates 41 are evenly distributed around the circumference of the limiting sleeve 3 axis, pressurized airflow is introduced into different spiral grooves 31 from multiple directions. The airflow inside each spiral groove 31 flows along the spiral groove 31, thus forming three spiral airflows outside the limiting sleeve 3. Each spiral airflow... All of these components are enclosed on the outside of the limiting sleeve 3. Due to the enveloping effect of the airflow, the limiting sleeve 3 is helped to maintain stability. At the same time, since the elastic sleeve 8 and the limiting sleeve 3 cooperate, that is, a part of the elastic sleeve 8 is fitted on the outside of the limiting sleeve 3, and the spiral protrusion 82 and spiral protrusion 83 are respectively fitted in the two spiral grooves 31, when the limiting sleeve 3 vibrates laterally or vertically, the elastic sleeve 8 can reduce the vibration, thereby effectively ensuring the stability of the limiting sleeve 3 and reducing the shaking and displacement of the limiting sleeve 3. Since the stability of the limiting sleeve 3 is ensured, it is further convenient to ensure the stability of the fixing post 2, thereby improving the stability of the tapping head 21, that is, reducing the vibration of the tapping head 21 and reducing the displacement of the tapping head 21, which helps to ensure the tapping quality.

[0045] At the same time, the airflow in the spiral groove 31 is discharged into the guide bucket 62 from its bottom end, and the airflow is discharged downward through the guide bucket 62. The airflow flows around the tapping head 21, thereby cooling the tapping head 21. When the external pressure air source is a cold flow, the cooling effect on the tapping head 21 can be improved, reducing or avoiding the reduction in tapping accuracy caused by the heat of the tapping head 21.

[0046] Example 2

[0047] Please see Figure 1 , Figure 10 as well as Figure 11 Based on Embodiment 1, the moving component 5 includes a lead screw 52, ​​which is rotatably mounted on the support frame 1 via a bearing. The lead screw 52 is threadedly connected to the moving frame 6. Specifically, the moving frame 6 is provided with a threaded hole that matches the lead screw 52, ​​and the lead screw 52 engages with the threaded hole. The moving component 5 also includes a first drive motor 51 mounted on the support frame 1, and the output end of the first drive motor 51 is fixedly connected to the top end of the lead screw 52.

[0048] In addition, the moving component 5 also includes two linear slide rails 53 mounted on the support frame 1. The two linear slide rails 53 are vertically mounted and parallel to each other. Each linear slide rail 53 is fitted with a slider 54, which is fixedly connected to the moving frame 6.

[0049] In this embodiment, the first drive motor 51 drives the lead screw 52 to rotate, which in turn drives the moving frame 6 to move up and down, thereby enabling the tapping head 21 to descend for tapping operation. After tapping is completed, the tapping head 21, the moving frame 6, etc. can be reset.

[0050] Example 3

[0051] Please see Figure 1 and Figure 3 Based on implementation two, the upper part of the fixed column 2, which is not covered by the limiting sleeve 3, is connected and fixed to the upper part of the tapping head 21 by screws; the tapping head 21 can be removed by unscrewing the disassembly screws; the fixed sleeve can be made of transparent material, which can facilitate the replacement and installation of the tapping head 21.
