Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, and in particular to a laser clamping and positioning device for pipe fittings. Background Technology

[0002] In the field of laser processing, especially in the laser cutting and welding of pipes, the performance of fixtures and positioning devices plays a crucial role in processing accuracy and efficiency. Most existing pipe laser processing fixtures employ cavity-surface contact positioning. While this design can meet basic processing requirements, it presents several problems in practical applications. For example, insufficient positioning accuracy leads to processing deviations, low clamping efficiency affects production speed, and low automation levels mean that operation relies on manual labor, increasing labor intensity and quality fluctuations caused by human factors. These problems are particularly prominent in modern industrial production where high precision and high efficiency are required.

[0003] To overcome the above problems, some improvements have been made in the prior art. Chinese patent CN221185118 U discloses a "Lightweight Laser Fixture", which relates to the field of laser technology. It discloses a lightweight laser fixture; this technology is a fixture specifically designed for laser processing. It can fix materials on a processing table and process materials using a laser; the operation is simple and can be completed by a single person; this technology is mainly used for sheet metal parts, but it is not suitable for tubular parts and does not have a positioning device.

[0004] Chinese patent CN207873504 U discloses a "Laser Crimping Fixture," and this utility model discloses a laser cleaving fixture. This utility model's laser cleaving fixture employs an adjustable clamping device, which clamps the product to be cut by raising and lowering a cylinder. The cylinder pressure does not deform the product. Various support devices are available, allowing for different support devices to be used depending on the product's shape. The support devices can be directly mounted on a beam or installed using pads. This utility model can improve the processing efficiency and quality of automotive sheet metal parts. This technology is mainly used in automotive sheet metal parts. Its positioning method relies on the part's cavity for positioning, without dedicated positioning pins, which can lead to substandard product quality after laser cleaving, increasing the defect rate. It is not suitable for pipe fittings.

[0005] Chinese patent CN211680510 U discloses "A Laser Fixture", which relates to the field of laser fixture technology and solves the positioning problem of laser fixtures. The technology uses positioning columns and elastic components to make the laser fixture adapt to the internal surface fluctuations of the workpiece. It avoids gaps between the fixture and the workpiece when the opening size increases or decreases, thus ensuring processing accuracy. By adjusting the distance between the material thickness support blocks, it can adapt to the situation of different opening parts and has a high fault tolerance rate. However, the disadvantages are low automation, low work efficiency and inability to meet the requirements of tubular parts.

[0006] Therefore, a laser clamping and positioning device for pipe fittings is needed to address the shortcomings of existing technologies. Utility Model Content

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0030] Reference Figure 1 As shown, the present invention provides a laser clamping and positioning device for pipe fittings, comprising:

[0031] Support structure 1; it includes a base 11, an adjusting block assembly 12 and a support block 13, wherein the base 11 is disposed on the support block 13 and the adjusting block assembly 12 is disposed on the base 11;

[0032] A contouring support assembly, disposed on the adjusting block assembly 12, is used to support the pipe fitting and can be dynamically adjusted in position on the adjusting block assembly 12 according to the size and shape of the pipe fitting. The contouring support assembly includes a plurality of contouring support blocks arranged at intervals. The specific number of contouring support blocks is determined according to the length of the pipe fitting, with the purpose of stabilizing the placement during the laser process and improving laser accuracy. In this embodiment, the contouring support assembly includes a first contouring support block 2, a second contouring support block 3, and a third contouring support block 4: the first contouring support block 2 and the second contouring support block 3 are respectively disposed on both sides of the third contouring support block 4.

[0033] A fixing device is provided on the support structure 1. The fixing device includes a clamping mechanism and a limiting mechanism. The clamping mechanism cooperates with the contour support block to clamp and fix the pipe fitting. The limiting mechanism is used to limit the end of the pipe fitting. In this embodiment, the clamping mechanism includes a first clamping mechanism 5 and a second clamping mechanism 6. The first clamping mechanism 5 and the second clamping mechanism 6 are respectively configured to clamp and fix the pipe fitting with the first contour support block 2 and the second contour support block 3. The limiting mechanism includes a first limiting mechanism 7 and a second limiting mechanism 8, which are respectively disposed at both ends of the support structure 1 to limit the end of the pipe fitting.

[0034] Furthermore, the base 11 includes a set of main beams 111 and several crossbeams 112; the adjusting block assembly 12 includes multiple adjusting blocks, each of which has multiple sets of pin holes and threaded holes. This design allows operators to quickly adjust the position of the adjusting block assembly 12 according to the specific size and shape of the pipe fitting, thereby achieving more precise positioning. In addition, the main beams 111 and crossbeams 112 of the base 11 provide sufficient rigidity and strength, ensuring the stability of the fixture during processing and further improving processing accuracy.

[0035] The bottom of each of the contour support blocks is provided with a first pad 9, and the first pad 9 has several mounting holes. Specifically, the bottom of the first contour support block 2, the second contour support block 3, and the third contour support block 4 are all provided with the first pad 9. The design of the first pad 9 not only increases the support area and improves the stability of the fixture, but also provides more adjustment options through the mounting holes, enabling the fixture to more accurately adapt to the shape and size of different pipe fittings, further improving processing accuracy and adaptability.

[0036] The bottom of each limiting mechanism is provided with a second pad 10, and the second pad 10 is provided with several mounting holes. Specifically, the bottom of both the first limiting mechanism 7 and the second limiting mechanism 8 is provided with a second pad 10, which not only increases the support area and improves the stability of the clamp, but also provides more adjustment options through the mounting holes, so that the clamp can more accurately adapt to the shape and size of different pipe fittings, further improving the processing accuracy and adaptability.

[0037] An angle adjustment block 101 is provided between the limiting mechanism and the second pad 10. In this embodiment, an angle adjustment block 101 is provided between the first limiting mechanism 7 and the second pad 10. The angle adjustment block 101 provides additional adjustment function, enabling the first limiting mechanism 7 to adapt to pipe fittings with different angles for adjustment. This design not only improves the versatility and flexibility of the fixture, but also further improves the processing accuracy, especially for pipe fittings that require processing at a specific angle, which can significantly improve the processing quality.

[0038] like Figure 2 As shown, the clamping mechanism includes a first support base 51, a first lifting drive device 52, a first pressing arm 53, a contouring clamping block 54, and a positioning component 55. The first lifting drive device 52 is mounted on the first support base 51. The first pressing arm 53 is connected to the driving end of the first lifting drive device 52. The contouring clamping block 54 is connected to the first pressing arm 53. The positioning component 55 is located between the contouring clamping block 54 and the first support base 51, and is used to limit the position of the contouring clamping block 54.

[0039] Initially, the contour clamp 54 is raised to allow the pipe fitting to be inserted smoothly. Once the pipe fitting is in place, the first lifting drive device 52 activates, driving the first clamping arm 53 to move downwards. The downward movement of the first clamping arm 53 causes the contour clamp 54 to move downwards until it contacts the pipe fitting and applies clamping force. During this movement, the positioning component 55 ensures that the contour clamp 54 accurately reaches the predetermined position. After the contour clamp 54 contacts the pipe fitting and applies clamping force, the pipe fitting is precisely clamped, ensuring no displacement occurs during processing. After processing is completed, the first lifting drive device 52 activates, driving the first clamping arm 53 to move upwards. The upward movement of the first clamping arm 53 causes the contour clamp 54 to move upwards, releasing it from the pipe fitting.

[0040] like Figure 3 As shown, the limiting mechanism includes a second support base 71, a second lifting drive device 72, a second pressing arm 73, a positioning support arm 74, a positioning pin 75, and a positioning component 55. The second lifting drive device 72 is mounted on the second support base 71. The second pressing arm 73 is connected to the drive end of the second lifting drive device 72. The positioning support arm 74 is connected to the second pressing arm 73. The positioning pin 75 is vertically mounted on the positioning support arm 74. The positioning component 55 is located between the second support base 71 and the positioning support arm 74, and is used to limit the position of the positioning pin 75. The positioning support arm 74 is provided with a handle for manually controlling the lifting and lowering of the positioning support arm 74.

[0041] Before the pipe fitting is placed, the positioning pins 75 of both the first limiting mechanism 7 and the second limiting mechanism 8 are in the raised state to ensure the pipe fitting can be smoothly placed into the clamp. The second lifting drive device 72 is in standby mode. After the pipe fitting is placed in place, the second lifting drive device 72 is activated, driving the second clamping arm 73 to move downwards. The downward movement of the second clamping arm 73 causes the positioning support arm 74 and the positioning pin 75 to move downwards until the positioning pin 75 is inserted into the end positioning hole of the pipe fitting. During the movement, the second limiting mechanism 8 restricts the position of the positioning pin 75 to ensure that the positioning pin 75 can be accurately inserted into the positioning hole, avoiding over-insertion or under-insertion, and ensuring the stability and accuracy of the clamping process. After the positioning pin 75 is inserted into the end positioning hole of the pipe fitting, the pipe fitting is precisely clamped, ensuring that no displacement occurs during processing. After processing is completed, the second lifting drive device 72 is activated, driving the second clamping arm 73 to move upwards. The upward movement of the second clamping arm 73 causes the positioning support arm 74 and the positioning pin 75 to move upwards, and the positioning pin 75 is withdrawn from the positioning hole of the pipe fitting.

[0042] like Figure 4 As shown, the positioning component 55 includes a first support block 551, a positioning protrusion 552, a second support block 553, and a positioning groove 554. The positioning protrusion 552 is disposed on the first support block 551, and the positioning groove 554 is disposed on the second support block 553, with the positioning groove 554 corresponding vertically to the positioning protrusion 552. The cooperation between the positioning protrusion 552 and the positioning groove 554 ensures a uniform distribution of clamping force, preventing pipe deformation or clamping failure due to uneven clamping force. This design not only improves the stability and reliability of the fixture but also ensures the accuracy and consistency of the clamping process through the cooperation between the positioning protrusion 552 and the positioning groove 554, further improving processing accuracy and product quality.

[0043] In this embodiment, both the first lifting drive device 52 and the second lifting drive device 72 include a cylinder and a power source that provides power to the cylinder.

[0044] Furthermore, a protective cover is provided on the outside of the cylinder. The protective cover can effectively prevent external factors (such as dust, debris, etc.) from interfering with and damaging the cylinder, extend the service life of the cylinder, ensure the stability and reliability of the fixture in long-term use, and further improve processing quality and production efficiency.

[0045] The specific working process of the tube fitting laser clamping and positioning device based on the above structure is as follows:

[0046] In the initial state, the contouring clamping blocks 54 of the first clamping mechanism 5 and the second clamping mechanism 6 are in the raised state, and the positioning pins 75 of the first limiting mechanism 7 and the second limiting mechanism 8 are also in the raised state, so that the pipe can be smoothly placed into the clamp; the first lifting drive device 52 and the second lifting drive device 72 are in the standby state, ready to act according to subsequent operation instructions.

[0047] The operator places the pipe fitting on the first contour support block 2, the second contour support block 3, and the third contour support block 4. According to the shape and size of the pipe fitting, the position is adjusted by adjusting the pin holes and threaded holes on the adjusting block assembly 12 to provide initial support and positioning for the pipe fitting.

[0048] Once the pipe fitting is in place, the first lifting drive device 52 of the first clamping mechanism 5 and the second clamping mechanism 6 activates, driving the first clamping arm 53 to move downwards. The downward movement of the first clamping arm 53 causes the contour clamping block 54 to move downwards until the contour clamping block 54 contacts the pipe fitting and applies clamping force. During the movement, the positioning component 55 ensures that the contour clamping block 54 accurately reaches the predetermined position, so that the pipe fitting is precisely clamped, ensuring that no displacement occurs during processing.

[0049] The second lifting drive device 72 of the first limiting mechanism 7 and the second limiting mechanism 8 actuates, driving the second clamping arm 73 to move downwards. The downward movement of the second clamping arm 73 causes the positioning support arm 74 and the positioning pin 75 to move downwards until the positioning pin 75 is inserted into the end positioning hole of the pipe fitting. During the movement, the positioning component 55 restricts the position of the positioning pin 75, ensuring that the positioning pin 75 can be accurately inserted into the positioning hole, avoiding over-insertion or under-insertion of the positioning pin 75, and ensuring the stability and accuracy of the clamping process. After the positioning pin 75 is inserted into the end positioning hole of the pipe fitting, the pipe fitting is further precisely clamped, ensuring that no displacement occurs during processing.

[0050] After the pipe fitting is securely clamped, the laser machine begins processing it. Because the pipe fitting is precisely positioned and stably fixed in the fixture, it will not shift during processing, thus ensuring processing accuracy and quality.

[0051] After processing, the first lifting drive device 52 of the first clamping mechanism 5 and the second clamping mechanism 6 activates, driving the first clamping arm 53 to move upward. The upward movement of the first clamping arm 53 causes the contour clamping block 54 to move upward, and the contour clamping block 54 is released from the pipe fitting. At the same time, the second lifting drive device 72 activates, driving the second clamping arm 73 to move upward. The upward movement of the second clamping arm 73 causes the positioning support arm 74 and the positioning pin 75 to move upward, and the positioning pin 75 is withdrawn from the positioning hole of the pipe fitting.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
