Description

A tapping device for surface machining of metal cabinets Technical Field

[0001] This invention relates to the field of metal cabinet processing technology, and in particular to a tapping device for surface processing of metal cabinets. Background Technology

[0002] Tapping is the process of creating internal threads on the surface of an object using a tap. It is a core process in cabinet assembly and fastening.

[0003] Currently, when tapping the surface of metal cabinets, internal threads are usually machined by using a tap to cut pre-drilled holes in thin plates such as cold-rolled steel, stainless steel, and aluminum alloy. Before cutting the metal plates, they need to be precisely positioned. Traditional positioning devices mostly use blocks to abut against the outer side of the plate to limit its movement. However, when the blocks are used for limiting, they abut against the outer side of the plate, so personnel need to actively move the blocks when disassembling and placing the plates, resulting in low efficiency in placing and disassembling the plates during processing. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a tapping device for processing the surface of metal cabinets. The designed structure solves the problem of low replacement efficiency caused by the limitation of traditional sheet metal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tapping device for surface processing of metal cabinets, comprising a processing platform, and four pads fixed on the processing platform, wherein the pads are provided with multiple insertion holes, and positioning plates are installed on the pads by bolts; and a primary positioning part fixed on two positioning plates and a secondary positioning part on the other two positioning plates, wherein the primary positioning part comprises two rotating columns rotatably mounted on the positioning plates, and positioning arms that abut against the outer side of the plate are fixed on the two rotating columns, and adjusting arms are fixed on the outer side of the two rotating columns; adjusting members for controlling the opening and closing of the two adjusting arms are installed on the positioning plates; the secondary positioning part comprises an active clamping member that abuts against the outer side of the plate and an auxiliary lifting member for lifting the plate.

[0006] Preferably, the active clamping component includes a positioning post fixed to the positioning plate, a rotating shell rotatably mounted on the outer side of the positioning post, a clamping arm for positioning the plate fixed on the outer side of the rotating shell, and a torsion spring fixed inside the rotating shell and fixed to the positioning post. A connecting plate is fixed on the positioning plate, and an insert post is slidably inserted into the connecting plate. An opening component for adjusting the rotation of the rotating shell is fixed at one end of the insert post.

[0007] Preferably, the opening component includes a connecting tube fixed to one end of the insertion post, an adjusting plate fixed to the outside of the connecting tube, a frosting disc adapted to the adjusting plate fixed to the outside of the rotating shell, and a magnetic block magnetically attracted to the connecting plate fixed to the outside of the connecting tube.

[0008] Preferably, the outer ends of the positioning arm and the clamping arm are fixed with rubber posts that abut against the outer side of the plate.

[0009] Preferably, the adjusting plate is located between the two grinding discs, and the outer side of the adjusting plate is provided with anti-slip texture.

[0010] Preferably, the adjusting component includes a slide rod fixed to the positioning plate, an adjusting seat slidably sleeved on the outside of the slide rod, an adjusting post fixed at the bottom of the adjusting seat that fits against both sides of the adjusting arm, a compression spring sleeved on the outside of the slide rod that abuts against the outside of the adjusting seat, and a locking component installed on the adjusting seat.

[0011] Preferably, the locking component includes a locking rod that is slidably inserted into the adjusting seat, a limiting plate is fixed at the bottom of the locking rod, and a locking spring that abuts against the limiting plate is sleeved on the outer side of the locking rod.

[0014] Preferably, the locking rod is located at one end of the adjusting seat away from the center, so as not to affect the sliding of the adjusting seat on the slide rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention optimizes the traditional plate positioning structure.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] The following description is intended to disclose the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0020] Example 1: Please refer to Figures 1-6. A tapping device for metal cabinet surface processing includes a processing platform 1, and four pads 2 fixed on the processing platform 1. The pads 2 have multiple insertion holes, and positioning plates 3 are installed on the pads 2 by bolts. It also includes a primary positioning part 4 fixed on two positioning plates 3 and a secondary positioning part 5 fixed on the other two positioning plates 3. The primary positioning part 4 includes two rotating columns 6 rotatably mounted on the positioning plates 3. Positioning arms 7 that abut against the outer side of the plate are fixed on the two rotating columns 6. Adjusting arms 8 are fixed to the outer side of the two rotating columns 6. Adjusting components 9 that control the opening and closing of the two adjusting arms 8 are installed on the positioning plates 3. The secondary positioning part 5 includes an active clamping component 10 that abuts against the outer side of the plate and an auxiliary lifting component 11 for lifting the plate. In this solution, by optimizing the traditional method of plate positioning, the cooperation between the primary positioning part 4 and the secondary positioning part 5 achieves rapid positioning and convenient disassembly. It can be applied to fields requiring positioning and disassembly, such as plate tapping processing and furniture assembly.

[0021] Furthermore, the active clamping component 10 includes a positioning post 12 fixed on the positioning plate 3. A rotating shell 13 is rotatably mounted on the outer side of the positioning post 12. A clamping arm 14 for positioning the plate is fixed on the outer side of the rotating shell 13. A torsion spring fixed to the positioning post 12 is fixed inside the rotating shell 13. A connecting plate 15 is fixed on the positioning plate 3. An insert post 16 is slidably inserted into the connecting plate 15. An opening component 17 for rotating and adjusting the rotating shell 13 is fixed at one end of the insert post 16. It should be noted that the torsion spring designed inside the rotating shell 13 generates elastic force, which drives the clamping arm 14 to abut against the outer side of the plate, thereby achieving abutment positioning of the plate. When opening, personnel need to use the opening component 17 to rotate the rotating shell 13 in the opposite direction to open the clamping arm 14, facilitating the removal of the plate. It should also be noted that, in order to avoid damage to the outer side of the plate, rubber posts 21 that abut against the outer side of the plate are fixed at the outer ends of the positioning arm 7 and the clamping arm 14.

[0022] The opening component 17 includes a connecting tube 18 fixed to one end of the insertion post 16. An adjusting plate 19 is fixed to the outside of the connecting tube 18. A frosting disc 20 adapted to the adjusting plate 19 is fixed to the outside of the rotating shell 13. A magnetic block that magnetically attracts the connecting plate 15 is fixed to the outside of the connecting tube 18. It should be noted that the adjusting plate 19 is located between the two frosting discs 20, and the outside of the adjusting plate 19 is provided with anti-slip texture.

[0023] When adjusting the rotation of the rotating shell 13 using the opening part 17, the operator only needs to push the adjustment plate 19 towards the two sanding discs 20, causing the two sanding discs 20 to rotate in opposite directions, so that the two clamping arms 14 open in opposite directions and disengage from the plate. When the plate needs to be positioned later, the operator only needs to release the plate. Under the magnetic attraction of the magnetic block, the adjustment plate 19 will be moved back, and the torsion spring inside the rotating shell 13 will cause the clamping arms 14 to abut against the outside of the plate.

[0024] Referring to Figures 5 and 6, the adjusting component 9 includes a slide rod 22 fixed on the positioning plate 3, an adjusting seat 23 slidingly sleeved on the outside of the slide rod 22, an adjusting post 24 fixed at the bottom of the adjusting seat 23 and fitting against both sides of the adjusting arm 8, a compression spring 25 sleeved on the outside of the slide rod 22 and abutting against the outside of the adjusting seat 23, and a locking component 26 installed on the adjusting seat 23.

[0025] The locking component 26 includes a locking rod 27 that is slidably inserted into the adjusting seat 23. A limiting plate 28 is fixed at the bottom of the locking rod 27. A locking spring 29 that abuts against the limiting plate 28 is sleeved on the outside of the locking rod 27. A locking hole 30 that matches the locking rod 27 is provided on the positioning plate 3.

[0026] To prevent the locking rod 27 from contacting the slide rod 22 and affecting the movement of the adjusting seat 23 on the slide rod 22, the locking rod 27 is located at the end of the adjusting seat 23 away from the center, so as not to affect the sliding of the adjusting seat 23 on the slide rod 22.

[0027] In this solution, the principle of opening and closing the positioning arm 7 is utilized by the adjusting component 9. First, the operator holds the adjusting seat 23, causing it to move along the slide rod 22. As the adjusting seat 23 moves towards the plate along the slide rod 22, it drives the two adjusting arms 8 to rotate accordingly, causing the two positioning arms 7 to abut against the plate, thus positioning the plate. Then, when the plate needs to be disassembled, the operator only needs to move the adjusting seat 23 backward along the slide rod 22, thereby achieving the reverse adjustment of the adjusting arms 8, enabling the opening operation between the positioning arm 7 and the plate. At the same time, under the action of the locking spring 29, the locking rod 27 moves towards the locking hole 30, achieving a temporary locking operation. By moving the adjusting seat 23 on the slide rod 22, the positioning arm 7 is opened and closed.

[0028] Example 2: Please refer to Figures 1-4. This embodiment further explains Example 1, and the difference is that it discloses one specific embodiment of the auxiliary lifting member 11.

[0029] Specifically, the auxiliary lifting component 11 includes a lifting plate 31, a notch 32 on the positioning plate 3, the lifting plate 31 being rotatably mounted in the notch 32 via a pivot, an adjusting rod 33 being slidably inserted into the connecting pipe 18, an L-shaped opening 34 on the outer side of the connecting pipe 18, a slider 35 fixed to the outer side of the adjusting rod 33 and slidably engaging with the L-shaped opening 34, an end cap fixed to the top of the adjusting rod 33, and a push-opening spring 36 abutting against the end cap on the outer side of the adjusting rod 33. To facilitate lifting the sheet metal, a support plate 37 is fixed to one end of the lifting plate 31. In this design, after tapping the sheet metal, to facilitate... For easy disassembly and replacement of the sheet metal, when the operator moves the connecting pipe 18 and the adjusting plate 19, the rotating shell 13 is rotated, which opens the two clamping arms 14. Then, the operator presses down the adjusting rod 33, which squeezes and lifts one end of the plate 31, causing the support plate 37 at the other end to tilt up, thus lifting the sheet metal. At the same time, the operator rotates the adjusting rod 33, which causes the slider 35 to move down and then horizontally from the L-shaped opening 34 to lock. The adjusting rod 33 is engaged with one end of the notch 32 to limit the movement, thus ensuring that the clamping arms 14 remain open, making it convenient for the operator to replace the sheet metal.
