Description

Technical Field

[0001] The invention relates to the field of metal parts welding mechanisms, in particular to an electric welding mechanism for producing air spring metal cover plates. Background Art

[0002] Air spring, also known as gas spring, is a new type of shock-absorbing spring. It uses gas as the working medium and achieves shock absorption through the compression and relaxation of gas. The upper and lower covers of air spring are important components of air spring. They can protect the air spring and prevent deformation and damage of the air spring due to external environmental factors. They can enhance the structural strength of the air spring so that it can better withstand various vibrations and impacts during vehicle driving. They can seal and prevent gas leakage inside the air spring and maintain the stability of air pressure. They can also position the air spring to ensure that it does not deviate or swing during use.

[0003] The existing electric welding mechanism used for the production of air spring metal cover plates is usually equipped with corresponding clamping devices. However, these clamping devices have obvious limitations when facing metal cover plates of different diameters and thicknesses. When metal cover plates of different specifications need to be processed, especially when the diameter and thickness of the cover plates change, the clamping device must be adjusted. Specifically, the operator first needs to measure the diameter and thickness of the metal cover plate, and then manually adjust the various components of the clamping device according to these size parameters. For those clamping devices that rely on mechanical structures (such as bolts and nuts) to adjust the clamping spacing and height, the operator needs to use tools to loosen or tighten the corresponding mechanical parts to change the clamping opening size and clamping force. This process not only takes a lot of time, but also has high requirements on the skills and experience of the operator. If the adjustment is improper, the metal cover plate may have problems such as position displacement and loose clamping during the welding process, which will affect the welding quality.

[0004] Therefore, an electric welding mechanism for producing a metal cover plate of an air spring is proposed. Summary of the invention

[0005] In view of the above problems, the present invention provides an electric welding mechanism for producing a metal cover plate of an air spring to solve the problems raised in the above background technology.

[0006] The technical solution of the present invention is:

[0007] An electric welding mechanism for producing a metal cover plate of an air spring comprises a control box and a processing table, wherein the processing table is fixedly connected to the top surface of the control box, a workpiece plate is arranged on the surface of the processing table, a limit assembly for pressing down the metal cover plate is arranged on the surface of the processing table, a guide assembly is arranged on the upper surface of the processing table, and a welding head is installed on the surface of the guide assembly;

[0008] The limit assembly includes a moving opening opened on the top surface of the processing table, and the moving opening extends to the interior of the control box, a hydraulic rod is fixedly connected to the top surface of the inner wall of the control box, the telescopic end of the hydraulic rod is fixedly connected to a support block located at the top of the moving opening, the top surface of the support block is fixedly connected to a connecting plate, a pressure plate is hinged on the surface of the connecting plate, an anti-sliding block is fixedly connected to the surface of one end of the pressure plate away from the connecting plate, a protrusion is arranged on the top surface of the control box, and a hinged rod is hinged between the protrusion and the pressure plate.

[0009] The working principle of the above technical solution is as follows:

[0010] Place the cover plate on the surface of the workpiece plate, and use the hydraulic rod to extend upward to make the pressure plate rotate from a vertical state with the connecting plate and the pressure plate hinge as the center. During the process, the hinge of the hinge rod and the protrusion is used to achieve stable flipping. When the anti-sliding block is pressed down on the surface of the cover plate, the drive of the hydraulic rod is stopped and welding can be carried out with the welding head.

[0011] In a further technical solution, the limit assembly also includes an installation groove, which is opened on the top surface of the processing table, the bottom end of the workpiece plate contacts the top of the installation groove, and the inner wall of the installation groove is rectangularly distributed with a first electric telescopic rod, the shell of the first electric telescopic rod is fixedly connected to the inner wall of the installation groove, and the telescopic end of the first electric telescopic rod is fixed to the bottom surface of the workpiece plate.

[0012] Through the above technical solution, the cover plate can be stably placed on the surface of the processing table for processing by pressing down the anti-sliding block and extending the first electric telescopic rod.

[0013] In a further technical solution, the articulated rod includes an articulated sleeve and a sliding bar. A sliding opening is provided on the surface of the articulated sleeve. The outer surface of the sliding bar slides with the inner wall of the sliding opening. The ends of the articulated sleeve and the sliding bar that are away from each other are fixedly connected with an articulated joint. The articulated sleeve is hinged to the side wall of the pressure plate through the articulated joint, and the sliding bar is hinged to the protrusion through the articulated joint.

[0014] Through the above technical scheme, when the metal cover plate placed on the workpiece plate is to be fixed, the hydraulic rod begins to extend upward. At this time, the pressure plate moves up. Since the pressure plate and the hinge sleeve in the hinge rod are hinged through the hinge joint, the pressure plate will push the hinge sleeve to move together, and the movement of the hinge sleeve will drive the sliding bar inside it to slide in the sliding mouth. The other end of the sliding bar is hinged to the protrusion through the hinge joint, so the sliding bar will rotate relative to the protrusion. In this process, since the two ends of the hinge rod are respectively hinged to the pressure plate and the protrusion, and the sliding bar and the hinge sleeve can slide relatively, the pressure plate can rotate stably with the connecting plate and the pressure plate hinge as the center of the circle. When the extension of the hydraulic rod presses the anti-sliding block down on the surface of the cover plate, the entire pressing and fixing action is completed, and the hinge rod also stops moving at this time.

[0015] In a further technical solution, the protrusion includes a guide sleeve and a support block. The bottom end of the support block is fixed on the top surface of the processing table, and the guide sleeve is arranged on the outer surface of the support block. A rectangularly distributed connecting spring is fixedly connected between the top surface of the inner wall of the guide sleeve and the top of the support block, and the guide sleeve is hinged to the slide bar.

[0016] Through the above technical scheme, during the process of pressing the pressure plate, due to the existence of the connecting spring, the guide sleeve can move slowly when it is pulled by the sliding bar, so that the impact force generated when the pressure plate is pressed down can be buffered, and the metal cover plate can be prevented from being deformed or damaged due to instantaneous excessive pressure. For metal cover plates of different thicknesses, the degree of pressure of the pressure plate is different, which causes the articulated rod to pull the guide sleeve to different distances. The connecting spring can automatically adjust the compression degree according to different pulling forces, so that the guide sleeve can remain stable at different positions. Therefore, no matter how the thickness of the metal cover plate changes, the entire mechanism can be adaptively adjusted to ensure that the pressure plate can effectively press the cover plate.

[0017] In a further technical solution, a second electric telescopic rod is rectangularly distributed on the top surface of the processing table, and the telescopic end of the second electric telescopic rod is fixedly connected to a bearing seat. The guide assembly includes a screw rod, and the outer surfaces of both ends of the screw rod are fixed to the inner wall of the bearing seat. A motor is arranged on the outer surface of the shell of one of the second electric telescopic rods, and the motor shell is fixedly connected to the shell of the second electric telescopic rod, and the output end of the motor is fixedly connected to the end of the screw rod. A guide rod is fixedly connected between two adjacent bearing seats, and a sliding sleeve is provided on the outer surface of the guide rod, and the sliding sleeve is threadedly connected to the screw rod. The outer surface of the sliding sleeve is fixedly connected to a mounting seat, and the welding head is mounted on the surface of the mounting seat.

[0018] Through the above technical solution, the motor drives the screw to rotate, and then the sleeve drives the welding head to move, so that the horizontal position of the welding head can be accurately controlled, so that the welding point can accurately fall on the part of the metal cover plate that needs to be welded, thereby ensuring the accuracy and consistency of the welding.

[0019] In a further technical solution, a stabilizing block is fixedly connected to the bottom surface of the shell of the second electric telescopic rod, a sliding block is fixedly connected to the bottom surface of the stabilizing block, a slideway is provided on the surface of the processing table, and the sliding block is slidably connected to the slideway.

[0020] Through the above technical solution, the sliding connection between the slider and the slide provides a stable guide for the movement of the second electric telescopic rod. In the process of adjusting the position of the welding head, the movement trajectory of the second electric telescopic rod is limited to the direction of the slide, avoiding its shaking and deviation in the horizontal direction, thereby realizing smooth and precise position adjustment, and ensuring that the welding head can accurately reach the predetermined welding position.

[0021] In a further technical solution, two of each of the workpiece plate, the connecting plate and the pressing plate are provided, and one end of the pressing plate away from the anti-sliding plate is hinged between the two connecting plates.

[0022] Through the above technical solution, two workpiece plates, a connecting plate and a pressing plate are provided, and the pressing plate is hinged between the two connecting plates, so that pressure can be applied to the metal cover plate from two opposite directions, thereby forming multi-station processing.

[0023] In a further technical solution, the slider and the slideway are both magnetic structures.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. When adjusting the position of the workpiece plate, the device only needs to start the first electric telescopic rod to quickly adjust the height position of the metal cover plate, without spending a lot of time on complex manual adjustments like traditional devices, thereby greatly shortening the processing preparation time and improving the overall production efficiency. The hydraulic rod is extended to drive the rotation of the pressure plate and the hinged rod component fixes the cover plate, making the operation more simple and direct, reducing the operating steps and improving the operating efficiency;

[0026] 2. The device can place the cover plate stably on the processing table by pressing down the anti-sliding block, extending the first electric telescopic rod and cooperating with the hinged rod, effectively avoiding the position displacement of the cover plate during welding. At the same time, it can provide stable and uniform clamping force during the processing of cover plates with different diameters and thicknesses. Compared with the traditional device that relies on mechanical structure to adjust the clamping force, the new mechanism can better adapt to covers of various specifications, thereby improving the stability of welding quality.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Example:

[0041] See also Figure 1-7 , an electric welding mechanism for producing a metal cover plate of an air spring, comprising a control box 1, a processing table 2, the processing table 2 being fixedly connected to the top surface of the control box 1, a workpiece plate 3 being arranged on the surface of the processing table 2, a limit assembly for pressing down the metal cover plate being arranged on the surface of the processing table 2, a guide assembly being arranged on the upper surface of the processing table 2, and a welding head 21 being installed on the surface of the guide assembly;

[0042] The limiting assembly includes a moving opening 5 opened on the top surface of the processing table 2, and the moving opening 5 penetrates into the interior of the control box 1, a hydraulic rod 4 is fixedly connected to the top surface of the inner wall of the control box 1, the telescopic end of the hydraulic rod 4 is fixedly connected to a support block 6 located at the top of the moving opening 5, the top surface of the support block 6 is fixedly connected to a connecting plate 7, a pressure plate 8 is hinged on the surface of the connecting plate 7, an anti-sliding block 9 is fixedly connected to the surface of the end of the pressure plate 8 away from the connecting plate 7, a protrusion 10 is arranged on the top surface of the control box 1, and a hinged rod 11 is hinged between the protrusion 10 and the pressure plate 8.

[0043] The working principle of the above technical solution is as follows:

[0044] Place the cover plate on the surface of the workpiece plate 3, and use the hydraulic rod 4 to extend upward to make the pressure plate 8 rotate from a vertical state with the hinge of the connecting plate 7 and the pressure plate 8 as the center. During the process, the hinge of the hinge rod 11 and the protrusion 10 is used for stable flipping. When the anti-sliding block 9 is pressed down on the surface of the cover plate, the drive of the hydraulic rod 4 is stopped and welding can be carried out with the welding head 21.

[0045] See also Figure 1-Figure 7 The limit assembly also includes a mounting groove 12, which is opened on the top surface of the processing table 2, and the bottom end of the workpiece plate 3 contacts the top of the mounting groove 12. The inner wall of the mounting groove 12 is rectangularly distributed with a first electric telescopic rod 13. The shell of the first electric telescopic rod 13 is fixedly connected to the inner wall of the mounting groove 12, and the telescopic end of the first electric telescopic rod 13 is fixed to the bottom surface of the workpiece plate 3.

[0046] By pressing down the anti-sliding block 9 and extending the first electric telescopic rod 13 , the cover plate can be stably placed on the surface of the processing table 2 for processing.

[0047] See also Figure 2 and Figure 7 The articulated rod 11 includes an articulated sleeve 111 and a slide bar 112. A slide opening 113 is provided on the surface of the articulated sleeve 111. The outer surface of the slide bar 112 slides with the inner wall of the slide opening 113. The ends of the articulated sleeve 111 and the slide bar 112 that are away from each other are fixedly connected with an articulated joint 114. The articulated sleeve 111 is hinged to the side wall of the pressure plate 8 through the articulated joint 114, and the slide bar 112 is hinged to the protrusion 10 through the articulated joint 114.

[0048] When the metal cover plate placed on the workpiece plate 3 is prepared to be fixed, the hydraulic rod 4 begins to extend upward. At this time, the pressing plate 8 moves up. Since the pressing plate 8 is hinged to the hinge sleeve 111 in the hinge rod 11 through the hinge joint 114, the pressing plate 8 will push the hinge sleeve 111 to move together, and the movement of the hinge sleeve 111 will drive the slide bar 112 inside it to slide in the slide mouth 113. The other end of the slide bar 112 is hinged to the protrusion 10 through the hinge joint 114, so that the slide bar 112 will rotate relative to the protrusion 10. In this process, since the two ends of the hinge rod 11 are respectively hinged to the pressing plate 8 and the protrusion 10, and the slide bar 112 and the hinge sleeve 111 can slide relatively, the pressing plate 8 can rotate stably with the hinge point of the connecting plate 7 and the pressing plate 8 as the center of the circle. When the extension of the hydraulic rod 4 causes the anti-sliding block 9 to press down on the surface of the cover plate, the entire pressing and fixing action is completed, and the hinge rod 11 also stops moving at this time.

[0049] See also Figure 2 and Figure 7 The protrusion 10 includes a guide sleeve 101 and a support block 102. The bottom end of the support block 102 is fixed to the top surface of the processing table 2. The guide sleeve 101 is sleeved on the outer surface of the support block 102. A rectangularly distributed connecting spring 103 is fixedly connected between the top surface of the inner wall of the guide sleeve 101 and the top of the support block 102. The guide sleeve 101 is hinged to the slide bar 112.

[0050] During the process of pressing the pressure plate 8, due to the existence of the connecting spring 103, the guide sleeve 101 can move slowly when it is pulled by the sliding bar 112, so as to buffer the impact force generated when the pressure plate 8 is pressed down, and avoid causing instantaneous excessive pressure on the metal cover plate to cause deformation and damage to the cover plate. For metal cover plates of different thicknesses, the degree of pressing of the pressure plate 8 is different, which causes the pulling distance of the guide sleeve 101 by the hinge rod 11 to be different. The connecting spring 103 can automatically adjust the compression degree according to different pulling forces, so that the guide sleeve 101 can remain stable at different positions. Therefore, no matter how the thickness of the metal cover plate changes, the entire mechanism can be adaptively adjusted to ensure that the pressure plate 8 can effectively press the cover plate.

[0051] See also Figure 1 and Figure 5A second electric telescopic rod 14 is distributed in a rectangular shape on the top surface of the processing table 2. The telescopic end of the second electric telescopic rod 14 is fixedly connected to a bearing seat 15. The guide assembly includes a screw 17. The outer surfaces of both ends of the screw 17 are fixed to the inner wall of the bearing seat 15. A motor 16 is provided on the outer surface of the shell of one of the second electric telescopic rods 14. The shell of the motor 16 is fixedly connected to the shell of the second electric telescopic rod 14. The output end of the motor 16 is fixedly connected to the end of the screw 17. A guide rod 19 is fixedly connected between two adjacent bearing seats 15. The outer surface of the guide rod 19 is sleeved with a sliding sleeve 18. The sliding sleeve 18 is threadedly connected to the screw 17. The outer surface of the sliding sleeve 18 is fixedly connected to a mounting seat 20, and a welding head 21 is mounted on the surface of the mounting seat 20.

[0052] By driving the lead screw 17 to rotate through the motor 16, the sleeve 18 then drives the welding head 21 to move, so that the horizontal position of the welding head 21 can be accurately controlled so that the welding point can accurately fall on the part of the metal cover plate that needs to be welded, thereby ensuring the accuracy and consistency of welding.

[0053] See also Figure 1 and Figure 4 A stabilizing block 22 is fixedly connected to the bottom surface of the shell of the second electric telescopic rod 14 , a slider 23 is fixedly connected to the bottom surface of the stabilizing block 22 , a slideway 24 is provided on the surface of the processing table 2 , and the slider 23 is slidably connected to the slideway 24 .

[0054] The sliding connection between the slider 23 and the slide 24 provides a stable guide for the movement of the second electric telescopic rod 14. During the process of adjusting the position of the welding head 21, the movement trajectory of the second electric telescopic rod 14 is limited to the direction of the slide 24, avoiding its shaking and deviation in the horizontal direction, thereby achieving smooth and precise position adjustment, ensuring that the welding head 21 can accurately reach the predetermined welding position.

[0055] There are two workpiece plates 3 , two connecting plates 7 and two pressure plates 8 , and one end of the pressure plate 8 away from the anti-sliding block 9 is hinged between the two connecting plates 7 .

[0056] Two workpiece plates 3, a connecting plate 7 and a pressing plate 8 are provided, and the pressing plate 8 is hinged between the two connecting plates 7, so that pressure can be applied to the metal cover plate from two opposite directions, thereby forming multi-station processing.

[0057] The slider 23 and the slideway 24 are both magnetic structures.

[0058] During operation, the air spring metal cover plate to be welded is placed on the workpiece plate 3. At this time, the workpiece plate 3 is located at the top of the installation groove 12. Then the hydraulic rod 4 is started, and the telescopic end of the hydraulic rod 4 extends upward, driving the support block 6 and the connecting plate 7 to move upward. Since the connecting plate 7 is hinged with the pressure plate 8, the pressure plate 8 will rotate with the hinge of the connecting plate 7 and the pressure plate 8 as the center of the circle. During the rotation of the pressure plate 8, the hinged rod 11 will move in coordination, wherein the slide bar 112 slides in the slide mouth 113 of the hinge sleeve 111. At the same time, the guide sleeve 101 moves on the support block 102 and compresses the connecting spring 103, so that the anti-sliding block 9 on the pressure plate 8 is stably pressed down on the surface of the cover plate, thereby firmly fixing the cover plate on the workpiece plate 3. In order to ensure the stability of the cover plate being clamped, the first electric telescopic rod 13 can be started when the anti-sliding block 9 is pressed down. According to the thickness of the metal cover plate, the The telescopic end of an electric telescopic rod 13 drives the workpiece plate 3 to move up and down in the mounting groove 12, so that the metal cover plate is adjusted to a suitable height position and clamped to ensure the accuracy of subsequent welding operations. After the cover plate is limited, the motor 16 is started, and the motor 16 drives the screw rod 17 to rotate. Since the screw rod 17 is threadedly connected with the sleeve 18, and the sleeve 18 is sleeved on the guide rod 19, the rotation of the screw rod 17 will cause the sleeve 18 to move along the guide rod 19. At the same time, the second electric telescopic rod 14 is telescopically adjusted according to the needs of the welding position. During the telescopic process, the slider 23 on the bottom surface of the stabilizing block 22 can be slid in the slideway 24 on the surface of the processing table 2, driving the welding head 21 on the mounting seat 20 to move to a suitable welding position. When the welding head 21 moves to a suitable position, the welding operation is started to perform electric welding on the metal cover plate fixed on the workpiece plate 3.

[0059] The above-mentioned embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
