[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0032] According to an embodiment of the present invention, a valve pipe crimping device is provided, comprising:

[0033] The housing fixing fixture 1 is used to support and fix the oil tank housing 2, and a metal connector for the valve pipe to be installed is fixed on the oil tank housing 2;

[0034] The clamping device 3 has a first state of clamping the valve tube and a second state of releasing the valve tube;

[0035] The lifting device 4 is connected to the clamping device 3 via the pressing device 5. The lifting device 4 is used to drive the clamping device 3 to move up and down, and the pressing device 5 is used to drive the clamping device 3 to move along the axial direction of the valve pipe.

[0036] A lateral adjustment device 6 is located above the housing fixing fixture 1. The lateral adjustment device 6 is connected to the lifting device 4 and is used to drive the lifting device 4 to move laterally.

[0037] The valve pipe crimping equipment provided in this embodiment adjusts the position of the valve pipe through the lateral adjustment device 6 and the lifting device 4, and drives the valve pipe to be crimped onto the metal joint through the crimping device 5. Thus, through the positioning and pressure control of the mechanical structure, the uncertainty of manual operation is reduced, the assembly accuracy and assembly success rate are improved, the labor intensity of operators is reduced, and the installation efficiency is improved.

[0038] Specifically, the housing fixing fixture 1 is used to stably fix and position the oil tank housing 2, so that the oil tank housing 2 will not shift or shake during the valve pipe crimping process. A metal connector is already fixedly installed on the oil tank housing 2 before it is placed on the housing fixing fixture 1. Furthermore, the metal connector has anti-slip textures on its wall to improve the connection strength after subsequent valve pipe crimping.

[0039] The clamping device 3 includes pneumatic or electric grippers, which clamp the valve tube. An elastic buffer pad is provided on the inside of the grippers to prevent excessive clamping force from deforming the valve tube.

[0040] The lateral adjustment device 6 drives the lifting device 4, crimping device 5, and clamping device 3 to move horizontally as a whole. The lifting device 4 drives the clamping device 3 and valve pipe to move vertically. Through horizontal and vertical displacement, the valve pipe is moved to the crimping position where its axis corresponds to the axis of the metal joint. The crimping device 5, as the crimping power source, drives the clamping device 3 to move linearly along the axial direction of the valve pipe after the valve pipe and metal joint are aligned, thereby crimping the valve pipe onto the metal joint and completing the assembly operation. The lateral adjustment device 6 and the lifting device 4 facilitate the adjustment of the valve pipe's position, thus adapting to the positional differences of metal joints on different models of oil tank housings, which helps improve the applicability of the valve pipe crimping equipment.

[0041] The specific workflow is as follows: First, fix the tank shell 2 onto the shell fixing fixture 1 to complete the positioning of the tank; place the valve pipe in the clamping position of the clamping device 3 and control the clamping device 3 to clamp the valve pipe; adjust the lateral position of the lifting device 4 through the lateral adjustment device 6, start the lifting device 4 to drive the valve pipe to rise and fall, so that the valve pipe is aligned with the metal joint; finally, start the crimping device 5 to drive the valve pipe to be crimped onto the metal joint along its axial direction. After the crimping is completed, all devices are reset and the next work cycle begins.

[0042] In one embodiment, combined Figure 2 and Figure 3As shown, the lifting device 4 is fixedly connected to the pressing device 5 via the connecting plate 7. The connecting plate 7 has a first through hole 71 and two first arc-shaped holes 72 located on both sides of the first through hole 71. The center of the first arc-shaped hole 72 is located on the axis of the first through hole 71. The lifting device 4 has a first mounting hole 431 corresponding to the first through hole 71 and a second mounting hole 432 corresponding to the first arc-shaped hole 72. The connecting plate 7 and the lifting device 4 are rotatably connected by a first rotating shaft installed in the first through hole 71 and the first mounting hole 431, and are fixedly connected by a first detachable fastener installed in the first arc-shaped hole 72 and the second mounting hole 432.

[0043] The valve pipe crimping equipment provided in this embodiment improves the adaptability of the valve pipe crimping equipment to valve pipe crimping requirements of different angles by setting a connecting plate 7 between the lifting device 4 and the crimping device 5 to adjust the tilt angle of the crimping device 5.

[0044] Specifically, the connecting plate 7 is L-shaped and includes a first side plate and a second side plate arranged perpendicularly to each other. The first side plate is connected to the lifting device 4, and the second side plate is connected to the pressing device 5. A first through hole 71 is provided on the first side plate. The diameter of the first through hole 71 is set according to the specifications of the first rotating shaft. Two first arc-shaped holes 72 are symmetrically provided on both sides of the first through hole 71. The center of the first arc-shaped hole 72 coincides with the axis of the first through hole 71. The width of the first arc-shaped hole 72 is slightly larger than the diameter of the first fastener, so that the first fastener can slide smoothly within the first arc-shaped hole 72. The lifting device 4 has a first mounting hole 431 corresponding to the first through hole 71 and a second mounting hole 432 corresponding one-to-one with the two first arc-shaped holes 72. The first detachable fastener includes a bolt or screw. Correspondingly, the inner walls of the first mounting hole 431 and the second mounting hole 432 are provided with internal threads for engagement with the bolt or screw. The main plane of the first side plate is parallel to the direction of gravity, and the axis of the first rotating shaft is parallel to the horizontal direction.

[0045] The connection between the connecting plate 7 and the lifting device 4 is as follows: a first rotating shaft passes through the first through hole 71 and the first mounting hole 431 to achieve a rotatable connection; a first detachable fastener passes through the first arc-shaped hole 72 and is threadedly connected to the second mounting hole 432 to achieve an adjustable fixation. When it is necessary to adjust the angle of the pressing device 5, simply loosen the first detachable fastener, and the connecting plate 7 can rotate around the first rotating shaft. After the angle is adjusted to the preset position, tighten the first detachable fastener again to complete the fixation.

[0046] In one embodiment, combined Figure 4As shown, the lifting device 4 includes a track seat 41 arranged in a vertical direction, a sliding seat 42 slidably arranged on the track seat 41, the sliding seat 42 being fixedly connected to the pressing device 5 through a connecting plate 7, and a driver 43 being arranged on the track seat 41, the driver 43 being connected to the sliding seat 42 and used to drive the sliding seat 42 to move in a vertical direction.

[0047] Specifically, the sliding seat 42 is slidably engaged with the track seat 41. A driver 43 is provided on the side of the track seat 41 opposite to the sliding seat 42. The driver 43 includes a cylinder, electric cylinder, or hydraulic cylinder arranged vertically, used to drive the sliding seat 42 to reciprocate vertically, thereby adjusting the height of the crimping device 5 and the clamping device 3. The first mounting hole 431 and the second mounting hole 432 are formed on the sliding seat 42.

[0048] In one embodiment, combined Figure 2 and Figure 3 As shown, the connecting plate 7 is also provided with a second through hole 73 and two second arc-shaped holes 74 located on both sides of the second through hole 73. The center of the second arc-shaped holes 74 is located on the axis of the second through hole 73. The crimping device 5 is provided with a third mounting hole 81 corresponding to the second through hole 73 and a fourth mounting hole 82 corresponding to the second arc-shaped holes 74. The connecting plate 7 and the crimping device 5 are rotatably connected by a second rotating shaft installed in the second through hole 73 and the third mounting hole 81, and are fixedly connected by a second detachable fastener installed in the second arc-shaped holes 74 and the fourth mounting hole 82.

[0049] The valve tube crimping equipment provided in this embodiment is fixedly and adjustablely connected to the crimping device 5 via the connecting plate 7, so as to adjust the crimping angle of the valve tube in another direction, thereby increasing the angle adjustment range of the valve tube and further improving the adaptability of the valve tube crimping equipment to the crimping requirements of valve tubes with different angles.

[0050] Specifically, the second side plate has a second through hole 73 and two second arc-shaped holes 74 symmetrically distributed on both sides of the second through hole 73. The center of the second arc-shaped hole 74 coincides with the axis of the second through hole 73, and its structural design is similar to that of the first arc-shaped hole 72. Correspondingly, the crimping device 5 has a third mounting hole 81 coaxial with the second through hole 73 and a fourth mounting hole 82 corresponding to each of the two second arc-shaped holes 74. The second detachable fastener includes a bolt or screw, and the third mounting hole 81 and the fourth mounting hole 82 are provided with internal threads. The main plane of the second side plate is perpendicular to the main plane of the first side plate, and the axis of the second rotating shaft is perpendicular to the axis of the first rotating shaft.

[0051] The connection method between the connecting plate 7 and the pressing device 5 is similar to that between the connecting plate 7 and the lifting device 4: a rotatable connection is achieved by the second rotating shaft passing through the second through hole 73 and the third mounting hole 81; the two are fixed by a second detachable fastener passing through the second arc-shaped hole 74 and threadedly connected to the fourth mounting hole 82. During actual adjustment, the operator can adjust the tilt angle of the valve pipe in two directions through the first arc-shaped hole 72 and the second arc-shaped hole 74 respectively.

[0052] In one embodiment, combined Figures 1 to 4 As shown, the crimping device 5 includes a fixed frame 51 connected to the lifting device 4, and a linear drive device 52 fixedly connected to the fixed frame 51. The clamping device 3 is disposed inside the fixed frame 51. The linear drive device 52 is connected to the clamping device 3 and is used to drive the clamping device 3 to move along the axial direction of the valve pipe.

[0053] Specifically, one side of the fixed frame 51 is fixedly connected to the connecting plate 7, and the third mounting hole 81 and the fourth mounting hole 82 are formed on the fixed frame 51. The fixed frame 51 has a accommodating space for accommodating the clamping device 3 to move axially along the valve pipe. A linear drive device 52 is disposed outside the fixed frame 51, and its output end is fixedly connected to the clamping device 3 for driving the clamping device 3 to move axially along the valve pipe. The linear drive device 52 includes a cylinder or a servo electric cylinder. Furthermore, a pressure sensor is also provided at the output end of the linear drive device 52 for real-time detection of the clamping force. A displacement sensor is provided on the fixed frame 51 for detecting the moving distance of the clamping device 3.

[0054] In one embodiment, combined Figure 5 As shown, the housing fixing fixture 1 includes multiple support structures 11 and multiple pressing mechanisms 12. The top of the support structure 11 is adapted to abut against the lower surface of the oil tank housing 2. The pressing mechanism 12 includes a telescopic device 121 arranged in the vertical direction. A pressure rod 122 is provided at the upper end of the telescopic device 121. The pressure rod 122 is used to abut against the upper surface of the oil tank housing 2.

[0055] Specifically, the number of support structures 11 and pressing mechanisms 12 can be configured according to the size and weight of the tank housing 2. The height of the support structure 11 is adjustable. The support structure 11 can be a vertically arranged cylinder, electric cylinder, or hydraulic cylinder, or it can be a vertically arranged inner and outer sleeve structure. The relative position of the inner and outer sleeves in their axial direction can be adjusted by adjusting the threads or locking bolts between the inner and outer sleeves, thereby adjusting its overall height. By adjusting the height of the support structure 11, multiple support structures 11 can fit against the lower surface of the tank housing 2, achieving multi-point uniform support and preventing deformation of the tank housing 2 due to uneven force. A pad is provided on the top of the support structure 11 to prevent scratches on the surface of the tank housing 2.

[0056] The bottom of the telescopic device 121 is fixed to the base of the housing fixing fixture 1, and the upper end is connected to the pressure rod 122. When the oil tank housing 2 is placed on the support structure 11, the telescopic device 121 drives the pressure rod 122 to move downward, so that the lower surface of the pressure rod 122 abuts against the upper surface of the oil tank housing 2, thereby fixing the oil tank housing 2. The telescopic device 121 includes a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder.

[0057] By utilizing the height-adjustable function of the support structure 11 and the telescopic adjustment function of the pressing mechanism 12, the housing fixing fixture 1 can be adapted to different models of oil tank housings 2, thereby improving the versatility of the housing fixing fixture 1.

[0058] Furthermore, the pressure rod 122 is rotatably connected to the upper end of the telescopic device 121, and has a third state in which one end away from the telescopic device 121 is located above the tank housing 2, and a fourth state in which it avoids the upper part of the tank housing 2.

[0059] In one embodiment, combined Figure 1 and Figure 4 As shown, the valve pipe crimping equipment also includes a first support frame 9, and a support platform 91 for fixing the housing fixing fixture 1 is provided on the upper end of the first support frame 9.

[0060] Specifically, the first support frame 9 adopts a frame structure, which is welded together from columns, beams and reinforcing ribs. The height of the first support frame 9 can be designed according to the operator's working habits and the height requirements of the automated production line, so as to facilitate the operator to load and unload materials and perform equipment maintenance.

[0061] The upper end of the first support frame 9 is provided with a support platform 91, which provides a flat base for the installation of the shell fixing fixture 1. The support platform 91 has multiple waist-shaped mounting holes. The shell fixing fixture 1 is fixedly connected to the support platform 91 by bolts passing through the waist-shaped holes. The waist-shaped holes facilitate the fine-tuning of the position of the shell fixing fixture 1 on the support platform 91.

[0062] In one embodiment, combined Figure 1 and Figure 4 As shown, the valve pipe crimping equipment also includes a second support frame 10, which is connected to the lateral adjustment device 6 and is used to support the lateral adjustment device 6.

[0063] Specifically, the second support frame 10 is independently installed or connected and fixed to the first support frame 9. The second support frame 10 also adopts a frame structure, welded from columns, beams, and reinforcing ribs. Its height is higher than the first support frame 9, allowing the lateral adjustment device 6 to be positioned above the housing fixing fixture 1, providing sufficient space for the lifting movement of the lifting device 4. Furthermore, leveling bolts are provided at the bottom of the second support frame 10 to achieve horizontal leveling.

[0064] The top of the second support frame 10 is fixedly connected to the lateral adjustment device 6.

[0065] Furthermore, the second support frame 10 is provided with two fixed plates 14, which are respectively located at both ends of the lateral adjustment device 6. The length direction of the fixed plates 14 is perpendicular to the lateral movement direction of the lifting device 4. Multiple positioning holes are distributed along the length direction of the fixed plates 14. A movable plate 13 is detachably fixedly connected to each fixed plate 14. The movable plate 13 is fixedly connected to the lateral adjustment device 6. By connecting the movable plate 13 with different positioning holes, its position on the fixed plate 14 can be adjusted, thereby adjusting the position of the lateral adjustment device 6 along the lateral movement direction perpendicular to the lifting device 4, thereby further improving the movable range of the valve pipe and increasing the applicability of the valve pipe crimping equipment.

[0066] In one embodiment, combined Figure 1 As shown, the lateral adjustment device 6 includes a slide rail 61, a slider 62, and a drive structure 63. The slide rail 61 is arranged in the horizontal direction and is fixedly connected to the second support frame 10. The slider 62 is slidably arranged on the slide rail 61 and is connected to the lifting device 4. The drive structure 63 is connected to the slider 62 and is used to drive the slider 62 to move along the slide rail 61.

[0067] Specifically, the slide rail 61 is adjustablely and fixedly connected to the top of the second support frame 10 via the movable plate 13 and the fixed plate 14. The slide rail 61 is arranged horizontally, and the slider 62 is slidably mounted on the slide rail 61 and fixedly connected to the track seat 41 of the lifting device 4. Furthermore, limit blocks are provided at both ends of the slide rail 61. The limit blocks are made of elastic rubber and can buffer the slider 62 when it is impacted, thus protecting the equipment structure.

[0068] The drive structure 63 includes bearing seats 631 corresponding to both ends of the slide rail 61, and a lead screw 632 rotatably connected within the two bearing seats 631. The axis of the lead screw 632 is parallel to the length direction of the slide rail 61. The drive structure 63 also includes a connecting seat 634 fixedly connected to the slider 62. The connecting seat 634 has a threaded hole, and the lead screw 632 is threaded into the threaded hole. The drive structure 63 also includes a motor 633 that is drively connected to the lead screw 632. The motor 633 drives the lead screw 632 to rotate, thereby driving the slider 62 to move on the slide rail 61 via the connecting seat 634.

[0069] In one embodiment, combined Figures 1 to 5 As shown, the valve pipe crimping equipment also includes a control panel 15, which is electrically connected to the clamping device 3, the lifting device 4 and the lateral adjustment device 6 respectively.

[0070] Specifically, the control panel 15 includes an industrial touch screen all-in-one machine or a touch screen display connected to a PLC controller. The control panel 15 is electrically connected to the clamping device 3, the linear drive device 52, the driver 43, the motor 633, and various sensors to form a complete control system.

[0071] The control panel 15 has multiple physical or virtual operation buttons, including a reset button, forward button, lower button, clamping button, start button, and release button. The control panel 15 has preset and stored parameters such as crimping force, crimping stroke, lifting height, and lateral position. The control panel 15 also has a physical emergency stop button for emergency shutdown of the equipment.

[0072] The specific operating procedure is as follows: Press the reset button once, and the linear drive device 52, driver 43, and motor 633 will return to the preset initial position in sequence; after placing the oil tank housing 2, it will be clamped by the housing fixing fixture 1; press the forward button once, and the motor 633 will move, driving the lifting device 4 to the preset horizontal position; press the lower button again, and the driver 43 will move, driving the crimping device 5 and clamping device 3 to the preset vertical position; align the valve tube with the metal connector, press the clamping button once, and the clamping device 3 will move to clamp the valve tube; press the start button again, and the linear drive device 52 will move, driving the clamping device 3 and the valve tube to move, so as to crimp the valve tube onto the metal connector; press the release button once, and the clamping device 3 will move to release the valve tube; press the reset button again, and the linear drive device 52, driver 43, and motor 633 will return to the preset initial position; repeat the operation.

[0073] Specifically, when the crimping force reaches a preset value or the displacement reaches a preset stroke, the pressure sensor and displacement sensor send signals to the control panel 15 to stop the linear drive device 52, preventing overpressure from damaging the valve pipe or metal joint, and also preventing insufficient crimping from affecting the connection strength. By setting pressure and displacement sensors, precise control of the crimping process is achieved, which helps improve the consistency of product quality.

[0074] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
