The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.
[0024] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0025] Reference Figures 1 to 4 This application provides an adjustable clamping device for metal processing, including a base plate 1, a mounting assembly 3 on the top of the base plate 1, and a clamping assembly 2 on the top of the mounting assembly 3. The mounting assembly 3 includes a mounting plate 31 and a support plate 33. Two L-shaped clamping plates 39 are slidably connected to the bottom of the support plate 33. The mounting plate 31 is fixedly mounted on the top of the base plate 1. The mounting plate 31 has slots 32 on both the front and rear sides. The two L-shaped clamping plates 39 are respectively inserted into the front and rear slots 32. A mating frame 36 is fixedly mounted on the bottom of the support plate 33. The mating frame 36 fits against the top of the mounting plate 31. The base plate 1 has mounting holes 4 inside, through which the base plate 1 can be fixed on the processing table.
[0026] Side plates 34 are fixedly installed at the bottom of both ends of the support plate 33. A second screw 35 is rotatably connected between the two side plates 34. The second screw 35 passes through the interior of the corresponding mating frame 36. The threads on both sides of the center of the second screw 35 have different directions of rotation. Two L-shaped clamping plates 39 are respectively screwed to the outside of the threads of the second screw 35 with different directions of rotation. When the second screw 35 rotates, the two L-shaped clamping plates 39 will move closer or further away from each other under the action of the threads.
[0027] A second rotating rod 37 is rotatably connected to the side plate 34 near the front end of the support plate 33. A second knob 38 is fixedly installed on the front of the second rotating rod 37. The inner end of the second rotating rod 37 moves through the inside of the side plate 34 and is fixedly connected to the second screw 35. Rotating the second knob 38 can drive the second screw 35 to rotate through the second rotating rod 37.
[0028] The thread lead angle of the second screw 35 is less than the equivalent friction angle, which gives the second screw 35 a self-locking property. The outer side of the second screw 35 is coated with a protective and lubricating grease. The grease is a grease with strong adhesion, anti-leakage, wear resistance and anti-pollution properties, such as lithium-based grease.
[0029] The clamping assembly 2 includes a support frame 21. A connecting block 22 is fixedly installed at the bottom of the support frame 21. The connecting block 22 is fixedly connected to the support plate 33 through a detachable structure. The detachable structure includes an insert block provided at the bottom of the connecting block 22 and a slot opened at the top of the support plate 33. The insert block and the slot are compatible. The connecting block 22 and the support plate 33 are fixedly connected by bolts. A support block 24 is fixedly installed at the inner bottom of the support frame 21. A lower arc plate 23 is fixedly installed at the top of the support block 24. The lower arc plate 23 is used to support the metal pipe.
[0030] A first screw 26 is threaded through the top wall of the support frame 21. An upper arc plate 25 is rotatably connected to the bottom of the first screw 26. A limit rod 28 is fixedly installed on the top of the upper arc plate 25. The limit rod 28 moves through the inside of the support frame 21 and prevents the upper arc plate 25 from rotating with the first screw 26. A first knob 27 is fixedly installed on the top of the first screw 26. Rotating the first knob 27 can drive the first screw 26 to rotate, thereby driving the upper arc plate 25 to move up and down. The upper arc plate 25 is located directly above the lower arc plate 23. The upper arc plate 25 and the lower arc plate 23 cooperate to clamp the metal pipe.
[0031] The thread lead angle of the first screw 26 is less than the equivalent friction angle, which gives the first screw 26 a self-locking function. The outer side of the first screw 26 is coated with a protective and lubricating grease. The grease is a grease with strong adhesion, anti-leakage, wear resistance and anti-pollution, such as lithium-based grease.
[0032] The lower arc plate 23 and the upper arc plate 25 on different support frames 21 have different curvatures to accommodate metal pipes of different diameters.
[0033] Working principle: In use, first select the clamping assembly 2 with the corresponding lower arc plate 23 and upper arc plate 25 according to the diameter of the metal pipe fitting. Install the clamping assembly 2 onto the support plate 33 through a detachable structure, that is, insert the bottom of the connecting block 22 into the slot at the top of the support plate 33, and then fix the connecting block 22 to the support plate 33 with bolts.
[0034] Next, adjust the position of the support plate 33 on the mounting plate 31 according to the length of the metal pipe. Rotate the second knob 38, which drives the second screw 35 to rotate through the second rotating rod 37. Since the threads on both sides of the center of the second screw 35 rotate in different directions, the two L-shaped clamping plates 39 will move away from each other and disengage from the clamping groove 32 on the mounting plate 31. Then, push the support plate 33 to the appropriate position on the mounting plate 31. Rotate the second knob 38 in the opposite direction to bring the two L-shaped clamping plates 39 closer together and re-clamp them into the clamping groove 32, thus completing the fixation of the position of the support plate 33.
[0035] When clamping metal pipe fittings, place the fitting on the lower arc plate 23, rotate the first knob 27 to rotate the first screw 26, and the first screw 26 moves downward under the action of the thread, causing the upper arc plate 25 to move downward until the upper arc plate 25 is in close contact with the fitting, thus clamping the fitting. Because the first screw 26 has a self-locking function, the stability of the clamping is guaranteed.
[0036] If the pipe is long, multiple clamping components 2 can be installed on the mounting plate 31 as needed. Select the appropriate clamping components 2 according to the above method and adjust the position of each clamping component 2 for clamping, thereby ensuring the stability of the long pipe during the processing.
[0037] Furthermore, all contents not described in detail in this specification are existing technologies known to those skilled in the art, and all electrical components mentioned in this document are powered by external power supply lines.
[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
