Description

Technical Field

[0001] The invention relates to the technical field of copper tube processing, and more specifically to an adjustable clamping tool for copper tube processing. Background Art

[0002] The adjustable clamping tool for copper tube processing is a device used for copper tube processing. It has an adjustable function and can adapt to copper tubes of different diameters. It can clamp and fix copper tubes of different diameters to ensure the stability and precision of the copper tubes during processing. Its working principle is to clamp copper tubes of different diameters by adjusting and moving various components. For example, by turning the hand crank to drive the threaded rod to rotate, the threaded sleeve and the threaded column can be driven to move longitudinally and horizontally, and finally the copper tube can be accurately clamped. This design enables the tooling to adapt to a variety of copper tubes of different sizes, improves the flexibility and efficiency of processing, and is widely used in many fields such as air conditioning manufacturing and automobile manufacturing for copper tube cutting, flaring and other processing processes.

[0003] The existing clamping tool drives the threaded rod to rotate by turning the hand wheel, thereby driving the clamping plate to move, and then clamps and fixes the copper tube to achieve the clamping of copper tubes of different diameters. However, when the clamping tool is in use, it can only clamp and fix the copper tubes on the same straight line, and then process the copper tubes. When the clamping tool clamps the copper tube with a certain bending angle, the copper tube cannot be stably clamped and fixed, thereby affecting the subsequent processing of the copper tube and reducing the practicality of the clamping tool.

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 10 , an adjustable clamping tool for copper tube processing, comprising a base 1, a placing platform 2 is fixedly connected to the upper surface of the base 1, a No. 1 clamping structure 3 is arranged on one side of the upper surface of the placing platform 2, an adjusting component 4 is arranged on one side of the outer cylindrical surface of the placing platform 2, and the adjusting component 4 includes a fan-shaped groove 41 opened on the outer cylindrical surface of the placing platform 2 near the No. 1 clamping structure 3;

[0040] A rotating groove 42 is provided on one side of the inner wall of the fan-shaped groove 41, and a rotating ring 43 is rotatably connected inside the rotating groove 42. A mounting plate 44 is fixedly connected to one side of the outer cylindrical surface of the rotating ring 43, and the mounting plate 44 slides in the fan-shaped groove 41. A No. 2 clamping structure 45 is provided on the upper surface of the mounting plate 44, and the structure of the No. 1 clamping structure 3 is the same as that of the No. 2 clamping structure 45.

[0041] like Figure 2 As shown, an annular slide bar 46 is fixedly connected to one side of the upper surface of the base 1, and the annular slide bar 46 is located inside the fan-shaped groove 41. An annular slide groove 47 is opened on one side of the lower surface of the mounting plate 44, and the annular slide bar 46 is slidably connected to the annular slide groove 47.

[0042] like Figure 2 As shown, a triangular pointer 48 is fixedly connected to the middle position of one side of the outer surface of the mounting plate 44 , and a scale line 49 is opened at the upper end of one side of the outer circular surface of the base 1 , and the scale line 49 is close to the position of the fan-shaped groove 41 .

[0043] The existing clamping tool cannot stably clamp the copper tube with a certain bending angle, which affects the subsequent processing of the copper tube and reduces the practicality of the clamping tool. Therefore, an adjustment component 4 is set. First, according to the bending angle of the copper tube to be clamped, the mounting plate 44 is manually rotated so that the mounting plate 44 rotates inside the fan-shaped groove 41, and at the same time, the rotating ring 43 is rotated in the rotating groove 42, so that the mounting plate 44 rotates around the center position of the base 1 and the placement platform 2. When the mounting plate 44 rotates, the triangular pointer 48 is driven to rotate. Then, the mutual cooperation between the triangular pointer 48 and the scale line 49 provided on the outer cylindrical surface of the base 1 can accurately determine the rotation angle of the mounting plate 44, so that the No. 2 clamping structure 45 on the mounting plate 44 and the No. 1 clamping structure 3 on the base 1 are between the center position of the placement platform 2. The angle formed is the same as the bending angle of the copper tube to be clamped, and then the two sides of the copper tube are placed in the No. 1 clamping structure 3 and the No. 2 clamping structure 45 respectively, and then the No. 1 clamping structure 3 and the No. 2 clamping structure 45 are started to clamp and fix the two sides of the copper tube. By manually rotating the mounting plate 44, the angle formed between the No. 2 clamping structure 45 and the No. 1 clamping structure 3 and the center position of the placement platform 2 can be adjusted, so that the clamping tool can clamp and fix copper tubes with different bending angles, ensuring the stability of the clamping tool for the copper tube, facilitating the subsequent processing of the copper tube, and improving the practicality of the clamping tool. Through the sliding connection between the annular slide rod 46 and the annular slide groove 47, the stability of the rotation of the mounting plate 44 is improved, and one end of the mounting plate 44 can be prevented from tilting.

[0044] like Figure 2 , Figure 3 , Figure 4 As shown, a fixing component 5 is arranged inside the mounting plate 44, and the fixing component 5 includes a No. 1 slide groove 51 opened on both sides of the inner wall of the annular slide groove 47, and the two No. 1 slide grooves 51 are both slidably connected with clamping blocks 52, and the two No. 1 slide grooves 51 are commonly rotatably connected with a two-way threaded rod 53, and the two-way threaded rod 53 passes through the two clamping blocks 52 and is threadedly connected with the two clamping blocks 52, and a No. 1 mounting groove 54 is opened at a position away from the No. 1 slide groove 51 inside the mounting plate 44, and one end of the two-way threaded rod 53 extends to the No. 1 mounting groove 54 and is fixedly connected with a turbine 55, and a worm 56 is rotatably connected inside the No. 1 mounting groove 54 near the top of the turbine 55, and the worm 56 is meshingly connected with the turbine 55.

[0045] like Figure 4 As shown, one end of the worm 56 is fixedly connected to a straight rod 57 , and the straight rod 57 passes through the outer surface of the mounting plate 44 , and one end of the straight rod 57 passing through the outer surface of the mounting plate 44 is fixedly connected to a knob 58 .

[0046] In the above embodiment, the angle formed between the No. 2 clamping structure 45 and the No. 1 clamping structure 3 and the center position of the placement platform 2 is adjusted by rotating the mounting plate 44, and then the two sides of the copper tube are clamped by the No. 2 clamping structure 45 and the No. 1 clamping structure 3, so that the clamping tool can clamp and fix the copper tubes with different bending angles. However, because the mounting plate 44 rotates inside the fan-shaped groove 41, the mounting plate 44 drives the No. 2 clamping structure 45 to rotate to a suitable position, and the mounting plate 44 itself is prone to shaking, resulting in the position deviation of the No. 2 clamping structure 45, affecting the No. 2 clamping structure 45 to clamp one side of the copper tube, and it is necessary to manually and continuously adjust the position of the No. 2 clamping structure 45. Adjusting the position of the mounting plate 44 reduces the efficiency of the adjustment component 4, so a fixing component 5 is set. When the mounting plate 44 drives the second clamping structure 45 to move to the appropriate position, the knob 58 is manually rotated, and then the worm 56 is driven to rotate through the straight rod 57, thereby driving the turbine 55 to rotate, and at the same time driving the two-way threaded rod 53 to rotate, and then the two-way threaded rod 53 is threadedly connected with the two clamping blocks 52, which can drive the two clamping blocks 52 to move closer to each other, so that the two clamping blocks 52 clamp the annular slide bar 46, thereby fixing the mounting plate 44 and the annular slide bar 46, which can effectively prevent the mounting plate 44 itself from shaking, thereby improving the efficiency of the adjustment component 4.

[0047] like Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown, a positioning assembly 6 is arranged between the mounting plate 44 and the base 1, and the positioning assembly 6 includes a No. 2 slide groove 61 opened on the lower surface of the mounting plate 44 near the triangular pointer 48, a positioning rod 62 is slidably connected inside the No. 2 slide groove 61, a No. 1 spring 63 is arranged on the upper surface of the positioning rod 62, and arc-shaped positioning holes 64 evenly distributed are opened on the upper surface of the base 1 near the scale line 49.

[0048] like Figure 5 , Figure 6 , Figure 7 As shown, a No. 3 slide groove 66 is provided at the lower end of the inner wall of the positioning hole 64, and a slide plate 67 is slidably connected inside the No. 3 slide groove 66. An ejector rod 65 is fixedly connected to the upper surface of the slide plate 67, and the ejector rod 65 is slidably connected to the positioning hole 64. A No. 4 slide groove 69 is provided on one side of the outer circular surface of the base 1 near the No. 3 slide groove 66, and a connecting groove 68 is provided between the No. 3 slide groove 66 and the No. 4 slide groove 69. A rotating rod 611 is provided inside the connecting groove 68, and one end of the rotating rod 611 is located below the slide plate 67. Rotating shafts 612 are provided on both sides of the outer surface of the rotating rod 611, and the rotating shaft 612 is rotatably connected to the inside of the connecting groove 68.

[0049] like Figure 7As shown, the lower surface of the slide plate 67 is fixedly connected to a limiting ring 613, and one end of the rotating rod 611 is slidably connected to the inside of the limiting ring 613, the sliding rod 610 is slidably connected to the inside of the No. 4 slide groove 69, and a limiting groove 614 is provided on the lower side of the outer surface of the sliding rod 610 near the No. 3 slide groove 66, and the other end of the rotating rod 611 is slidably connected to the inside of the limiting groove 614.

[0050] In the above embodiment, the cooperation between the triangular pointer 48 and the scale line 49 can facilitate the worker to judge the rotation angle of the mounting plate 44, so as to accurately adjust the angle formed between the No. 2 clamping structure 45 and the No. 1 clamping structure 3 and the center position of the placement platform 2. However, it is difficult to accurately rotate the mounting plate 44 to a suitable angle by manually rotating the mounting plate 44, and the mounting plate 44 needs to be adjusted multiple times, so that the mounting plate 44 needs to take a certain amount of time to accurately rotate to a suitable angle, further reducing the use efficiency of the adjustment component 4. Therefore, a positioning component 6 is provided to judge the angle that the mounting plate 44 needs to rotate according to the bending angle of the copper tube, and then find the position of the corresponding angle on the scale line 49, and then manually drive the sliding rod 610 at the corresponding position to move upward in the No. 4 sliding groove 69, and at the same time drive one end of the rotating rod 611 to move upward through the limiting groove 614, so that the rotating rod 611 rotates around the rotating shaft 612 inside the connecting groove 68, so that the rotating rod 6 When the second slide groove 61 is rotated to the position just above the opened positioning hole 64, the positioning rod 62 is driven by the first spring 63 to move downward in the second slide groove 61, so that the positioning rod 62 is inserted into the positioning hole 64, thereby fixing the position of the mounting plate 44, and then the mounting plate 44 can be accurately rotated to the appropriate angle at one time, further improving the use efficiency of the adjustment assembly 4. Then, when the clamping tool is used, the sliding rod 610 is manually driven to move downward, thereby driving the ejector rod 65 to move downward, and the positioning rod 62 in the positioning hole 64 is ejected, so that the positioning rod 62 moves to the inside of the second slide groove 61, thereby facilitating the resetting of the mounting plate 44.

[0051] like Figure 7 , Figure 8 , Fig. 9 , Fig.10As shown, a stabilizing component 7 is provided between the slide bar 610 and the No. 4 slide groove 69, and the stabilizing component 7 includes a clamping groove 74 opened on both sides of the inner wall of the No. 4 slide groove 69, and a No. 5 slide groove 71 penetrating the slide bar 610 is opened on one side of the outer surface of the slide bar 610, and two No. 1 sliders 72 are slidably connected inside the No. 5 slide groove 71, and a No. 2 spring 75 is provided between the two No. 1 sliders 72, and a clamping block 73 is fixedly connected to the side of the outer surfaces of the two No. 1 sliders 72 away from each other.

[0052] like Fig. 9 , Fig.10 As shown, a control component 8 is arranged below the two No. 1 sliders 72, and the control component 8 includes a No. 6 slider 82 opened at the lower end of the inner wall of the No. 5 slider 71, and a No. 2 slider 83 is slidably connected inside the No. 6 slider 82, and trapezoidal blocks 84 are fixedly connected to both sides of the upper surface of the No. 2 slider 83, and trapezoidal grooves 81 are opened on the lower surfaces of the two No. 1 sliders 72, and the two trapezoidal blocks 84 are respectively inserted into the two trapezoidal grooves 81, and a No. 7 slider 85 penetrating the slide rod 610 is opened on one side of the inner wall of the No. 6 slider 82, and a No. 3 slider 86 is fixedly connected to one side of the outer surface of the No. 2 slider 83, and the No. 3 slider 86 penetrates the No. 7 slider 85 and is slidably connected to the No. 7 slider 85.

[0053] In the above embodiment, the slide bar 610 at the corresponding position is manually driven to move upward, thereby driving the corresponding ejector rod 65 to move downward, so that the positioning hole 64 is opened, and then the mounting plate 44 is rotated. When the No. 2 slide slot 61 is rotated to just above the opened positioning hole 64, the No. 1 spring 63 drives the positioning rod 62 to move downward and insert it into the positioning hole 64, so that the mounting plate 44 can be accurately rotated to a suitable angle at one time. However, because the positioning assembly 6 is provided with a plurality of positioning holes 64, when the mounting plate 44 is rotated, when the No. 2 slide slot 61 is rotated to just above the unopened positioning hole 64, the No. 1 spring 63 drives the positioning rod 62 to move downward, which will drive the ejector rod 65 in the unopened positioning hole 64 to move downward, so that the positioning rod 62 will be inserted into the unopened positioning hole 64, making it impossible for the mounting plate 44 to be accurately rotated to the appropriate angle at one time. Therefore, a stabilizing component 7 is provided, and the slide bar 610 is manually driven to move downward to drive the ejection rod 65 to move upward. When the upper surface of the ejection rod 65 coincides with the upper surface of the base 1, the two No. 1 slide blocks 72 are driven by the No. 2 spring 75 to move toward the outside of the No. 5 slide groove 71 at the same time, thereby driving the two clamping blocks 73 to move toward the outside of the No. 5 slide groove 71 at the same time, so that the two clamping blocks 73 are respectively inserted into the clamping grooves 74, thereby fixing the slide bar 610 in the No. 4 slide groove 69, and then fixing the ejection rod 65 in the positioning hole 64, which can prevent the positioning rod 62 from being inserted into the unopened positioning hole 64, thereby improving the use effect of the positioning component 6.

[0054] In the above embodiment, through the stabilizing assembly 7, when the ejector rod 65 moves upward and the upper surface of the ejector rod 65 coincides with the upper surface of the base 1, the ejector rod 65 is fixed in the positioning hole 64, but it is not convenient for the slide bar 610 to move upward, so a control assembly 8 is provided, firstly manually driving the No. 3 slide block 86 to move upward in the No. 7 slide groove 85, and at the same time driving the No. 2 slide block 83 to move upward in the No. 6 slide groove 82, thereby driving the two trapezoidal blocks 84 to move upward, so that the two trapezoidal blocks 84 are respectively inserted into the two trapezoidal grooves 81, thereby driving the two No. 1 slide blocks 72 to move closer to each other, so that the two clamping blocks 73 are withdrawn from the clamping groove 74 and moved to the No. 5 slide groove 71, thereby releasing the fixation of the slide bar 610, and then continuing to move the No. 3 slide block 86 upward, thereby driving the slide bar 610 to move upward, and then driving the ejector rod 65 to move downward, so that the slide bar 610 is convenient to move upward to drive the ejector rod 65 to move downward, thereby facilitating the use of the positioning assembly 6.

[0055] Instructions for use: First, determine the angle that the mounting plate 44 needs to rotate according to the bending angle of the copper tube to be clamped, then find the position of the corresponding angle on the scale line 49, move the No. 3 slider 86 upward, thereby starting the control component 8, driving the two blocks 73 to be pulled out of the slots 74 and move to the inside of the No. 5 slide slot 71, and then start the positioning component 6 to open the positioning holes 64 at the corresponding positions, and the unopened positioning holes 64 are fixed by the stabilizing component 7 to the ejector rod 65 in the unopened positioning holes 64, and then rotate the mounting plate 44. When the No. 2 slide slot 61 rotates to just above the opened positioning hole 64, the No. 1 spring 63 drives the positioning rod 62 to move downward in the No. 2 slide slot 61, so that the positioning rod 62 is inserted into the positioning hole 64, thereby fixing the position of the mounting plate 44, and then start the fixing component 5 to fix the mounting plate 44 and the annular slide bar 46, and then start the No. 1 clamping structure 3 and the No. 2 clamping structure 45 to clamp and fix the two sides of the copper tube.

[0056] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
