Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic cylinders, and particularly relates to a welding device for processing hydraulic cylinders. Background Technique

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy. It can achieve linear reciprocating motion. Hydraulic cylinders are widely used in the hydraulic systems of various machines, mainly due to their advantages such as simple structure, reliable operation, smooth movement, and no transmission clearance.

[0003] A Chinese patent with the publication number CN219900790U discloses a welding device for processing hydraulic cylinders, belonging to the technical field of cylinder barrel processing devices. Aiming at the problem that the hydraulic cylinder barrel is prone to offset during rotation, which easily causes a certain offset between the hydraulic cylinder barrels and results in poor quality of the welded finished product, it includes a workbench. A fixed seat is fixed at the middle position on the top of the workbench. A rotating plate is arranged on one side of the fixed seat. A rotating cylinder is rotatably connected through the middle position of the fixed seat. The two sides of the outer peripheral surface of the rotating cylinder are fixed to the inner wall at the middle position of the rotating plate. Another fixed sleeve on the outer peripheral surface of the rotating cylinder is provided with a first gear. An installation seat is fixed on the surface of the fixed seat away from the rotating plate. The utility model can avoid the situation that the cylinder barrel is offset due to its rotation by making the welding head do circular motion, thereby ensuring the quality of the welding process between the cylinder barrels and improving the practicability of the device.

[0004] As described above, this patent provides a welding device for processing hydraulic cylinders, which can avoid the offset during welding and ensure the welding quality. However, for the welding of hydraulic cylinders, its surface is circular. Therefore, during welding, it is necessary to ensure that it can be welded along the circular port. Otherwise, due to the time difference in welding at each part of the port, the welding degree and uniformity at each part will be different, and further the overall welding effect needs to be improved.

[0005] The utility model provides a welding device for processing hydraulic cylinders to solve the problems raised in the background technique.

[0006] To solve the above problems, the present utility model provides a hydraulic cylinder processing and welding device, including a workbench, a protective cover, a sliding seat and a rotation adjustment assembly. The bottom of the sliding seat is slidably connected to the top of the workbench; the rotation adjustment assembly includes a rotating annular frame; one side of the rotating annular frame is fixedly connected with a connecting clamping ring; the rotating annular frame is rotationally connected to one side of the sliding seat through the connecting clamping ring; the number of the rotating annular frames is set to two, and the two rotating annular frames are symmetrically arranged on both sides of the sliding seat; the surfaces of the two rotating annular frames are fixedly connected with connecting sleeves; a hydraulic rod is fixedly connected inside the connecting sleeve; one end of the hydraulic rod penetrates through the rotating annular frame and extends to the inner side of the rotating annular frame; one end of the hydraulic rod located inside the rotating annular frame is fixedly connected with an arc-shaped clamping block; a ring gear is fixedly connected to the surface of one of the rotating annular frames; a transmission gear is rotatably connected inside the sliding seat; the surface of the transmission gear meshes with the surface of the ring gear; a welding machine is fixedly connected to the top of the protective cover; an electric telescopic rod is fixedly connected to the bottom of the welding machine; one end of the electric telescopic rod penetrates through the protective cover and extends to the inside of the protective cover; a welding strip is clamped at one end of the electric telescopic rod located inside the protective cover.

[0007] Preferably: Support legs are fixedly connected to the bottom of the workbench; the surface of the protective cover is fixedly connected to one side of the top of the workbench; the number of the connecting sleeves is set to be multiple, and the multiple connecting sleeves are evenly arranged circumferentially on the surfaces of the two rotating annular frames.

[0008] Preferably: A motor cylinder is fixedly connected to one side of the sliding seat; a motor is fixedly connected inside the motor cylinder; the output shaft of the motor is fixedly connected to one side of the transmission gear through a coupling.

[0009] Preferably: Rotating auxiliary rings are rotatably connected to both sides of the protective cover; spring telescopic rods are fixedly connected to the inner sides of the rotating auxiliary rings; a clamping block is fixedly connected to one end of the spring telescopic rod; the number of the spring telescopic rods and the clamping blocks is set to be multiple, and the two spring telescopic rods and the clamping blocks are evenly arranged circumferentially on the surfaces of the rotating auxiliary rings.

[0010] Preferably: A sliding bottom block is fixedly connected to the bottom of the sliding seat; a limiting card slot adapted to the sliding bottom block is opened inside the workbench; an adjusting screw rod is rotatably connected to the inner wall of the limiting card slot; the surface of the adjusting screw rod is threadedly connected to the surface of the sliding bottom block; one end of the adjusting screw rod penetrates through the workbench and extends to one side of the workbench; an adjusting turntable is fixedly connected to one end of the adjusting screw rod located on one side of the workbench; limiting card rods are slidably connected to the top and bottom of the surface of the sliding bottom block where the adjusting screw rod is located; both ends of the limiting card rod are fixedly connected to the inner wall of the limiting card slot.

[0011] The beneficial effects of adopting the above technical solution are as follows:

[0012] By setting up the rotation adjustment component, during operation, place the two hydraulic cylinders to be welded inside the rotating annular frame and align their positions. At the same time, fixedly connect the sleeve on the surface of the rotating annular frame, and fix the hydraulic rod inside the sleeve. Utilize the operation of the hydraulic rod to drive the arc-shaped clamping block to move until it fits on the surface of the hydraulic cylinder, thereby completing the fixation of the hydraulic cylinder. In addition, when it is necessary to rotate and adjust the welding position, the driving gear rotates to drive the annular gear to start rotating, and then drives the rotating annular frame fixed to the annular gear to rotate. Since the annular gear is only set on the surface of one rotating annular frame, when performing rotation adjustment, it is necessary to first complete a small part of the welding of the butt-jointed hydraulic cylinders to achieve the positioning and fixation of the initial welding. And when one rotating annular frame can drive the hydraulic cylinder fixed inside it to rotate, it can also drive another hydraulic cylinder that has completed the initial welding and fixation with it to rotate, and make the rotating annular frame fixing the other hydraulic cylinder rotate on the sliding seat. Overall, it enables uniform rotation during welding, thereby realizing the function of welding while rotating, ensuring the uniformity during welding to a certain extent and improving the welding effect.

[0020] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and defined, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a movable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] As Figure 1 - Figure 4 Shown in the figure, in this embodiment, a hydraulic cylinder processing and welding device includes a workbench 1, a protective cover 2, a sliding seat 3 and a rotation adjustment assembly. The bottom of the sliding seat 3 is slidably connected to the top of the workbench 1; the rotation adjustment assembly includes a rotating ring frame 4; one side of the rotating ring frame 4 is fixedly connected with a connecting ring 5; the rotating ring frame 4 is rotatably connected to one side of the sliding seat 3 through the connecting ring 5; the number of the rotating ring frames 4 is set to two, and the two rotating ring frames 4 are symmetrically arranged on both sides of the sliding seat 3; both surfaces of the two rotating ring frames 4 are fixedly connected with connecting sleeves 6; a hydraulic rod 7 is fixedly connected to the inside of the connecting sleeve 6; one end of the hydraulic rod 7 penetrates through the rotating ring frame 4 and extends to the inside of the rotating ring frame 4; one end of the hydraulic rod 7 located inside the rotating ring frame 4 is fixedly connected with an arc-shaped clamping block 8; a ring gear 9 is fixedly connected to the surface of one of the rotating ring frames 4; a transmission gear 10 is rotatably connected to the inside of the sliding seat 3; the surface of the transmission gear 10 meshes with the surface of the ring gear 9; a welding machine 11 is fixedly connected to the top of the protective cover 2; an electric telescopic rod 12 is fixedly connected to the bottom of the welding machine 11; one end of the electric telescopic rod 12 penetrates through the protective cover 2 and extends to the inside of the protective cover 2; a welding rod 13 is clamped at one end of the electric telescopic rod 12 located inside the protective cover 2.

[0022] Through the above technical solution, the rotation adjustment assembly is arranged on the sliding seat 3. The rotating annular frame 4 can rotate on the surface of the sliding seat 3 through the connecting snap ring 5, and it is arranged on the rotating annular frame 4. When the rotation adjustment is completed, welding is carried out by the welding device 11. The welding device 11 drives the welding strip 13 to move up and down through the electric telescopic rod 12, so that after the welding strip 13 gradually shortens with welding, it can immediately fit on the surface of the hydraulic cylinder to ensure the welding effect. During work, the two hydraulic cylinders to be welded are placed in the rotating annular frame 4 and the positions are docked. At the same time, the connecting sleeve 6 is fixedly connected to the surface of the rotating annular frame 4, and the hydraulic rod 7 is fixed inside the connecting sleeve 6. The hydraulic rod 7 works to drive the arc-shaped block 8 to move until it fits on the surface of the hydraulic cylinder, thus completing the fixation of the hydraulic cylinder. In addition, when it is necessary to rotate and adjust the welding position, the driving gear 10 rotates to drive the annular gear 9 to start rotating, and then drives the rotating annular frame 4 fixed to the annular gear 9 to rotate. Since the annular gear 9 is only arranged on the surface of one rotating annular frame 4, when rotating and adjusting, it is necessary to first complete a small part of the welding of the butt-jointed hydraulic cylinders to achieve the positioning and fixation of the initial welding. And when the rotating annular frame 4 can drive the hydraulic cylinder fixed inside the rotating annular frame 4 to rotate, at the same time, the hydraulic cylinder can drive another hydraulic cylinder that has been initially welded and fixed with it to rotate, and the rotating annular frame 4 that fixes the other hydraulic cylinder rotates on the sliding seat 3, so that the welding can be rotated evenly during welding, thereby realizing the function of welding while rotating, ensuring the uniformity during welding to a certain extent and improving the welding effect.

[0023] As Figure 1 , Figure 3 and Figure 4 shown, a support leg 14 is fixedly connected to the bottom of the workbench 1; the surface of the protective cover 2 is fixedly connected to one side of the top of the workbench 1; the number of the connecting sleeves 6 is set to be multiple, and the multiple connecting sleeves 6 are evenly arranged circumferentially on the surfaces of the two rotating annular frames 4; a motor cylinder 15 is fixedly connected to one side of the sliding seat 3; a motor 16 is fixedly connected inside the motor cylinder 15; the output shaft of the motor 16 is fixedly connected to one side of the driving gear 10 through a coupling.

[0024] Through the above technical solution, the top end of the support leg 14 is fixed to the bottom of the workbench 1, and the workbench 1 is supported by the support leg 14. Multiple connecting sleeves 6 are arranged evenly circumferentially on the surface of the rotating annular frame 4, which can fix the hydraulic cylinder at multiple positions and ensure the stability during fixation. Finally, the motor cylinder 15 is fixed to one side of the sliding seat 3, and the motor 16 is fixed inside the motor cylinder 15. When the motor 16 works, it drives the driving gear 10 to start rotating through the output shaft, so as to provide energy for the rotation adjustment.

[0025] As Figure 2 - Figure 4 shown, both sides of the protective cover 2 are rotatably connected with rotating auxiliary rings 17; both inner sides of the rotating auxiliary rings 17 are fixedly connected with spring telescopic rods 18; one ends of the spring telescopic rods 18 are fixedly connected with clamping blocks 19; the number of the spring telescopic rods 18 and the clamping blocks 19 is set to be multiple, and the two spring telescopic rods 18 and the clamping blocks 19 are circumferentially and evenly arranged on the surface of the rotating auxiliary rings 17; the bottom of the sliding seat 3 is fixedly connected with a sliding bottom block 20; a limiting card slot 21 adapted to the sliding bottom block 20 is formed in the interior of the workbench 1; an adjusting screw rod 22 is rotatably connected to the inner wall of the limiting card slot 21; the surface of the adjusting screw rod 22 is threadedly connected with the surface of the sliding bottom block 20; one end of the adjusting screw rod 22 penetrates through the workbench 1 and extends to one side of the workbench 1; an adjusting turntable 23 is fixedly connected to the end of the adjusting screw rod 22 located on one side of the workbench 1; limiting clamping rods 24 are slidably connected to the surface of the sliding bottom block 20 and located at the top and bottom of the adjusting screw rod 22; both ends of the limiting clamping rods 24 are fixedly connected with the inner wall of the limiting card slot 21.

[0026] Through the above technical solution, rotating auxiliary rings are rotatably connected to both sides of the protective cover, spring telescopic rods are fixed inside the rotating auxiliary rings, the spring telescopic rods work to drive the clamping blocks to expand and contract. When the hydraulic cylinder penetrates into the rotating auxiliary ring, the clamping blocks can limit the hydraulic cylinder under the action of the spring telescopic rods, further completing the limiting support for the hydraulic cylinder and ensuring the stability during welding. In addition, a sliding bottom block is fixed to the bottom of the sliding seat, and a limiting card slot is formed in the interior of the workbench, enabling the sliding seat to slide inside the workbench through the cooperation of the sliding bottom block and the limiting card slot. When sliding is required, the adjusting turntable rotates to drive the adjusting screw rod to rotate, thereby driving the sliding bottom block to move, and the limiting clamping rods limit the sliding of the sliding bottom block, thereby driving the sliding seat to move, which can fine-tune the horizontal direction of the welding position to a certain extent and further improve the adaptability of use.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than limiting the technical solutions described in the present invention; therefore, although this specification has described the present invention in detail with reference to the above respective embodiments, those of ordinary skill in the art should understand that the present invention can still be modified or equivalently replaced, and all technical solutions and their improvements that do not depart from the spirit and scope of the present invention should be covered by the scope of the claims of the present invention; the technologies not detailed in the present invention are implemented by the prior art.
