[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to an embodiment of the present invention, a hydrogen tube end grinding device for hydrogen tube production is provided, comprising: a support plate 1, on one side of which two sliding grooves 2 are opened opposite each other;
[0032] Two sliders 3 are slidably installed in two grooves 2 respectively. A grinding plate 4 is fixedly installed in the slider 3, and the grinding surface of the grinding plate 4 is coplanar with one side of the slider 3 and one side of the support plate 1. Two elastic plates 5 are slidably installed on one side of the slider 3.
[0033] Several constraint rods 6 are rotatably mounted in corresponding elastic plates 5;
[0034] The adjustment mechanism 8, which is located on two sliders 3 and a support plate 1, is used to adjust the longitudinal height of several constraint rods 6.
[0035] Two drive mechanisms 7 are located at the upper and lower ends of the support plate 1, and are used to adjust the position of the two sliders 3 in the corresponding slide grooves 2.
[0036] In this embodiment, (please refer to...) Figure 1 As shown, support plate 1 is fixedly mounted on the support frame of the hydrogen tube grinding device's platform via connecting plates and bolts. The hydrogen tube grinding device mainly consists of a platform, a hydrogen tube electrical control clamping and fixing structure, a hydrogen tube drive structure, and a support frame. When using this improved hydrogen tube grinding device, please refer to... Figure 1As shown, firstly, according to the diameter of the hydrogen tube, the two sliders 3 are driven by the drive mechanism 7 to slide in the groove 2. (The two sides of the slider 3 protrude outward to form convex edges that contact the inner wall of the groove 2, thereby constraining the position of the slider 3 through the mutual contact between the convex edges and the inner wall of the groove 2, so that the slider 3 slides in a linear up-down trajectory) to adjust the distance between the two sliders 3 to the corresponding length. (The hydrogen tube polishing device is equipped with a control host to control the drive mechanism 7 and the adjustment mechanism 8).
[0037] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, after the distance between the two sliders 3 is adjusted, the hydrogen tube is clamped and fixed by the hydrogen tube electrical clamping and fixing structure, so that the tube opening of the hydrogen tube is inserted between the corresponding elastic plates 5. Then the adjustment mechanism 8 is started, and the elastic plates 5 are pulled towards the tube wall by several constraint rods 6. As the constraint rods 6 rotate within the elastic plates 5, the elastic plates 5 bend and deform to form a surface that fits against the inner or outer tube wall of the hydrogen tube, and fits tightly against the inner and outer tube walls of the hydrogen tube.
[0038] After the hydrogen tube is clamped and fixed, the drive structure drives the hydrogen tube to rotate. The side wall of the hydrogen tube opening slides against the grinding surface of the grinding plate 4 to complete the grinding process of the hydrogen tube opening. At the same time, several elastic plates 5 slide against the inner and outer walls of the hydrogen tube opening.
[0039] In summary, when this improved hydrogen tube polishing device is in use, it can adapt to polishing operations of hydrogen tube openings of various diameters within a certain range. Furthermore, due to the constraint of the elastic plate 5, when the polishing plate 4 is used to polish the opening of the hydrogen tube, the protrusions at the inner and outer circumferences of the opening will not bend to the inner and outer sides of the hydrogen tube due to the mutual contact between the polishing block and the protrusions, thereby avoiding a very small amount of protrusion residue and improving the polishing effect of the hydrogen tube opening.
[0040] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 3 As shown, several constraint rods 6 are divided into four groups and are arranged opposite each other on both sides of the two grinding plates 4. The spacing between two adjacent constraint rods 6 in each group is equal, and the two ends of the constraint rods 6 are coplanar with the two sides of the corresponding elastic plates 5.
[0041] In this embodiment, the two ends of the constraint rod 6 are coplanar with the two sides of the elastic plate 5, so that the side of the elastic plate 5 closest to the slider 3 fits into the side of the slider 3. This avoids the formation of a large gap between the elastic plate 5, the slider 3, and the side wall of the hydrogen tube opening when the elastic plate 5 fits into the inner tube wall of the hydrogen tube, which would affect the constraint and limiting of the slider 3 on the protrusion.
[0042] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the drive mechanism 7 includes a motor 71. Two motors 71 are fixedly mounted on the upper and lower ends of the support plate 1 respectively. A threaded shaft 72 is threaded through the center position of the slider 3. Both ends of the threaded shaft 72 are rotatably connected to the plate wall of the support plate 1, and the drive end of the motor 71 is fixedly connected to the corresponding threaded shaft 72.
[0043] In this embodiment, please refer to Figure 1 and Figure 3 As shown, when adjusting the position of slider 3 in the groove 2, motor 71 starts to drive the threaded rod to rotate. Due to the mutual contact between slider 3 and the inner wall of groove 2, the rotating threaded rod drives the two sliders 3 to move in opposite directions, thereby adjusting the distance between the two sliders 3 to adapt to the grinding operation of hydrogen energy pipe openings of different diameters.
[0044] In a further preferred embodiment of this utility model, such as Figure 3 , Figure 4 and Figure 5 As shown, the adjustment mechanism 8 includes several rectangular grooves 81, which are divided into eight groups and opened opposite each other on one side of the two sliders 3. A rectangular rod 82 is slidably installed in the rectangular groove 81, and one end of the rectangular rod 82 is fixedly connected to the corresponding constraint rod 6. A piston rod 83 is fixedly installed on the bottom side of the other end of the rectangular rod 82. A piston cylinder 84 is slidably sleeved on the outer periphery of the piston rod 83. An air extraction mechanism 85 is provided on the other side of the support plate 1 for extracting the air inside the piston cylinder 84.
[0045] In this embodiment, please refer to Figure 3 , Figure 4 and Figure 5 As shown, after the hydrogen tube is clamped and fixed, the pumping mechanism 85 is activated to continuously pump the gas inside the piston cylinder 84, thereby creating a negative pressure inside the piston cylinder 84. This applies a pulling force to the piston rod 83 towards the inside of the piston cylinder 84. At this time, part of the piston rod 83 gradually retracts into the piston cylinder 84, and the elastic plate 5 is pulled towards the tube wall of the hydrogen tube from multiple positions by the rectangular rod 82 and the constraint rod 6 until the elastic plate 5 comes into contact with the tube wall of the hydrogen tube. This causes the elastic plate 5 to bend and deform to form an arc surface that fits against the inner or outer tube wall of the hydrogen tube. This allows the elastic plate 5 to fit tightly against the inner or outer tube wall of the hydrogen tube, enabling the elastic plate 5 to adapt to the fitting of tube walls of hydrogen tubes of various diameters within a certain diameter range, thus enhancing the applicability of the device.
[0046] When the constraint rod 6 moves, due to the mutual contact between the rectangular rod 82 and the inner wall of the rectangular groove 81, a constraint limit can be applied to the constraint rod 6, so that the constraint rod 6 moves in a linear trajectory.
[0047] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the air extraction mechanism 85 includes an air extraction component 851, which is fixedly mounted in the middle of the other side of the support plate 1.
[0048] Two flow dividers 852 are opened opposite each other in the middle of the slider 3, and the two flow dividers 852 are located opposite each other on the outer periphery of the corresponding threaded shaft 72. The flow dividers 852 are located between the two sets of rectangular grooves 81. The piston cylinder 84 is inserted into the corresponding flow divider 852 at one end and is fixedly connected to the corresponding slider 3. The interior of the flow divider 852 is connected to the interior of the corresponding piston cylinder 84.
[0049] Two flexible tubes 853 are provided on the other side of the slider 3. One end of the flexible tube 853 is inserted into the corresponding diversion groove 852 and fixedly connected to the corresponding slider 3. The other end of the flexible tube 853 is threaded onto the corresponding air inlet end of the air extraction component 851.
[0050] In this embodiment, please refer to Figure 2 and Figure 4 As shown, when the gas in the piston cylinder 84 is extracted, the extraction component 851 is activated to continuously extract the gas in the diversion groove 852 through the flexible tube 853. (The extraction component 851 consists of a shell, two air pumps, several air inlets, and two exhaust ends, enabling the extraction component 851 to perform extraction or injection operations in the diversion groove 852.) As the gas in the diversion groove 852 is lost, a pressure difference is generated between the piston cylinder 84 and the diversion groove 852, causing the gas in the piston cylinder 84 to flow synchronously into the diversion groove 852. Ultimately, several piston cylinders 84 and the diversion groove 852 form a negative pressure chamber of the same strength, so that the tension on each part of the elastic plate 5 is equal, avoiding excessive tension on some parts of the elastic plate 5 and affecting the use of the device.
[0051] During the sliding process of slider 3 within slide groove 2, flexible tube 853 simultaneously undergoes bending deformation (flexible tube 853 can be a rubber tube or corrugated pipe or other deformable pipe) so that the interior of diversion groove 852 is always in communication with the interior of the extraction end of extraction component 851.
[0052] In a further preferred embodiment of this utility model, such as Figure 3 and Figure 4 As shown, a storage hole 854 is provided on one side of the slider 3 at the position corresponding to the soft tube 853, and the interior of the storage hole 854 is connected to the interior of the corresponding diversion groove 852. A pressure relief valve 855 is fixedly installed inside the storage hole 854.
[0053] In this embodiment, please refer to Figure 3 and Figure 4As shown, as the gas in the diversion channel 852 is lost, when the pressure in the diversion channel 852 reaches the threshold, the pressure difference across the pressure relief valve 855 also reaches the threshold simultaneously. At this time, external gas continuously flows through the pressure relief valve 855 into the diversion channel 852 to replenish the gas lost in the diversion channel 852, thereby preventing the device from being damaged due to excessive negative pressure in the piston cylinder 84.
[0054] Working principle:
[0055] According to the above-mentioned improved hydrogen tube end polishing device, the hydrogen tube end polishing process is completed. After the hydrogen tube end polishing is completed, the gas extraction component 851 is activated, and a corresponding amount of gas is injected into the diversion groove 852 through the soft tube 853 so that the gas pressure in the piston cylinder 84 is balanced with the outside. At the same time, due to the deformation and reset of the elastic plate 5, the piston rod 83 retracted into the piston cylinder 84 automatically slides out from the piston cylinder 84, and the positions of each part of the device are reset. The hydrogen tube is reinstalled according to the above-mentioned method, and the operation is repeated according to the above-mentioned method to continuously complete the polishing process of the hydrogen tube end.
[0056] It should be noted that, in conjunction with the automatic feeding device for hydrogen tubes, the grinding process of several hydrogen tube openings can also be completed automatically and sequentially through the control of the main unit.
[0057] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.
[0058] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
