Description

Technical Field

[0001] This application relates to the field of welding tooling technology, specifically a welding tooling for a hydraulic cylinder support assembly. Background Technology

[0002] A hydraulic cylinder support assembly is an important component used in automobiles or other mechanical equipment, primarily serving to support and secure the hydraulic cylinder. A hydraulic cylinder support assembly typically consists of several parts, including mounting plates, upright plates, and mounting holes. These components work together to ensure the stability and reliability of the hydraulic cylinder.

[0003] An existing patent (publication number: CN222199467U) discloses a welding fixture for a hydraulic cylinder support assembly, belonging to the field of welding fixture technology. It includes a welding fixture body, a flipping mechanism, and a fixing mechanism. The welding fixture body has the support assembly on it. The flipping mechanism is mounted on the welding fixture body and includes a pair of first supports, each with a gear mounted on it. A pair of racks are located under the welding fixture body, meshing with the gears. A pair of second supports are fixedly mounted under the welding fixture body. This utility model provides a hydraulic cylinder support assembly that, through the corresponding mechanism on the welding fixture, allows the hydraulic cylinder support assembly to be flipped to the other side when welding is required. Simultaneously, the stability of the hydraulic cylinder support assembly is maintained during the flipping process, thus replacing manual flipping and making the flipping of the hydraulic cylinder support assembly more convenient and faster.

[0004] Although the device in the aforementioned comparative document solves the problem of not being able to flip the cylinder support assembly during welding, the device has a fixed height and lacks a height adjustment structure, making it inconvenient for people to adjust the height of the device and unable to accommodate workers of different heights. In order to solve the above problems, a welding fixture for the cylinder support assembly is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a welding fixture for a hydraulic cylinder support assembly, which has the advantage of a height-adjustable structure, solving the problem that it is inconvenient for people to adjust the height of the device and cannot accommodate workers of different heights.

[0006] To achieve the above objectives, this application provides the following technical solution: a welding fixture for a hydraulic cylinder support assembly, comprising a support plate and a workpiece, wherein a welding device is provided on the top of the support plate, a through hole is provided inside the support plate, a fixing ring is fixedly connected to the side of the support plate, a rotating ring is rotatably connected inside the fixing ring, a fixing box is fixedly connected inside the rotating ring, two L-shaped sliding rods are slidably connected inside the fixing box, and clamping plates are fixedly connected to the sides of the L-shaped sliding rods, and the workpiece is located between the two clamping plates;

[0007] Telescopic rods are fixedly connected to the four corners of the bottom of the support plate. A U-shaped plate is fixedly connected to the bottom of the through hole. An X-shaped frame is fixedly connected between the four telescopic rods. A fixed cylinder is fixedly connected inside the U-shaped plate. A stepper motor is fixedly connected to the top of the X-shaped frame. A threaded rod is fixedly connected to the output end of the stepper motor. A threaded cylinder is fixedly connected to the top of the fixed cylinder. The threaded rod is threaded into the threaded cylinder. A folding sleeve is fixedly connected between the fixed cylinder and the X-shaped frame. The stepper motor is located inside the folding sleeve. A second electric push rod is fixedly connected to the four corners of the top of the U-shaped plate. A placement plate is fixedly connected to the top of the second electric push rod. The workpiece is placed on top of the placement plate.

[0008] The above scheme, by setting a stepper motor, allows the threaded rod to rotate when the height of the device needs to be adjusted. Through the limiting of multiple telescopic rods, the threaded cylinder can be moved on the surface of the threaded rod, thereby adjusting the position of the threaded cylinder on the surface of the threaded rod, thus adjusting the height of the device. This makes the device more convenient for workers of different heights to use. By setting a second electric push rod, the position of the placement plate can be adjusted. When the placement plate moves down, it provides space for the rotation of the workpiece. When the placement plate moves up, it makes it easier for people to support the workpiece.

[0009] Furthermore, a rotary motor is fixedly connected to the top of the support plate, a rotary gear is fixedly connected to the output end of the rotary motor, an annular rack is fixedly connected to the surface of the rotary ring, a meshing groove is opened on the surface of the fixed ring, the rotary gear is located in the meshing groove and meshes with the annular rack.

[0010] The above solution, by setting up a rotary motor, can make the rotary gear rotate. Through the meshing of the rotary gear and the ring rack, the rotary ring can be driven to rotate, which can drive the workpiece to rotate around the axis, thus solving the problem of low efficiency of manual flipping.

[0011] Furthermore, a first electric push rod is fixedly connected to the side of the fixed box, a strip groove is opened on the side of the fixed box, and a sliding groove and a sliding slot are opened on the other side of the fixed box, and the L-shaped slide rod is slidably connected in the sliding slot.

[0012] The above scheme, by setting a first electric push rod, can provide power transmission for the clamping action.

[0013] Furthermore, a sliding rack is fixedly connected to the side of the L-shaped slide rod, and a transmission gear is movably connected to the inside side of the fixed box via a pin. The transmission gear meshes with the sliding rack. A connecting rod is fixedly connected to the side of one of the L-shaped slide rods, and one end of the first electric push rod is fixedly connected to the surface of the connecting rod.

[0014] Through the above scheme, the linear motion of the first electric push rod can be converted into the synchronous reverse motion of the L-shaped slide rod by the meshing of the transmission gear and the sliding rack, thus ensuring clamping symmetry.

[0015] Furthermore, a sliding block is fixedly connected to the side of the clamping plate, and the sliding block is slidably connected in the sliding groove.

[0016] With the above solution, the sliding block is slidably connected in the sliding groove, which makes the clamping plate move more stably when it moves.

[0017] Furthermore, a sponge pad is fixedly connected to the side of the clamping plate.

[0018] The above solution, by setting up a sponge pad, can avoid a rigid structure between the clamping plate and the workpiece.

[0019] Furthermore, a protective shell is fixedly connected to the top of the support plate, and the rotating gear is located inside the protective shell.

[0020] The above solution, by setting up a protective shell, can protect the rotating gear and the ring rack, preventing them from getting dusty.

[0021] Furthermore, a support block is fixedly connected to the bottom end of the telescopic rod.

[0022] By implementing the above solution and setting up support blocks, the stability of the bottom of the telescopic pole can be enhanced, preventing it from tilting.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This hydraulic cylinder support assembly welding fixture, by incorporating a stepper motor, allows for height adjustment when the device's height needs to be adjusted. The stepper motor rotates the threaded rod, and through the limiting action of multiple telescopic rods, it moves the threaded cylinder on the surface of the threaded rod, thereby adjusting the position of the threaded cylinder and thus the height of the device. This makes the device suitable for workers of different heights, making it more convenient to use. Furthermore, by incorporating a second electric push rod and a second electric push-running rod, the position of the placement plate can be adjusted. When the placement plate moves downward, it provides space for the workpiece to rotate; when the placement plate moves upward, it facilitates support for the workpiece. Attached Figure Description

A second electric push rod 1021 is fixedly connected to the four corners of the top of the U-shaped plate 1020. A release mechanism is fixedly connected to the top of the second electric push rod 1021. The workpiece 3 is placed on top of the placement plate 1022. A stepper motor 1029 is installed. When the height of the device needs to be adjusted, the stepper motor 1029 operates, causing the threaded rod 1030 to rotate. Through the limiting action of multiple telescopic rods 1023, the threaded cylinder 1027 can be moved on the surface of the threaded rod 1030, thereby adjusting the position of the threaded cylinder 1027 on the surface of the threaded rod 1030. This allows the device to be adapted to workers of different heights, making it more convenient to use. A second electric push rod 1021 is installed. When the second electric push rod 1021 operates, the position of the placement plate 1022 can be adjusted. When the placement plate 1022 moves downward, it provides space for the rotation of the workpiece 3; when the placement plate 1022 moves upward, it facilitates support for the workpiece 3.

[0037] Please see Figure 2 , Figure 3 and Figure 5A rotary motor 103 is fixedly connected to the top of the support plate 1.

By setting the rotary motor 103, the rotary gear 104 can be rotated when the rotary motor 103 is running. Through the meshing of the rotary gear 104 and the ring rack 107, the rotating ring 105 can be driven to rotate, which can drive the workpiece 3 to rotate around the axis, solving the problem of low efficiency of manual flipping. A first electric push rod 1010 is fixedly connected to the side of the fixed box 106. A strip groove 1011 is opened on the side of the fixed box 106.

One end of the first electric push rod 1010 is fixedly connected to the surface of the connecting rod 1019, and the power is transmitted through the transmission gear... The meshing of 1012 with the sliding rack 1015 can convert the linear motion of the first electric push rod 1010 into the synchronous reverse motion of the L-shaped slide rod 1014, ensuring clamping symmetry. A sliding block 1018 is fixedly connected to the side of the clamping plate 1017. The sliding block 1018 is slidably connected in the sliding groove 1016. By sliding the sliding block 1018 in the sliding groove 1016, the clamping plate 1017 can move more stably when it moves.

[0038] Please see Figure 3 , Figure 4 and Figure 5 A sponge pad 1031 is fixedly connected to the side of the clamping plate 1017. By setting the sponge pad 1031, the clamping plate 1017 and the workpiece 3 can be prevented from forming a rigid structure. A protective shell 109 is fixedly connected to the top of the support plate 1. The rotating gear 104 is located inside the protective shell 109. By setting the protective shell 109, the rotating gear 104 and the ring rack 107 can be protected and prevented from getting dusty. A support block 1024 is fixedly connected to the bottom of the telescopic rod 1023. By setting the support block 1024, the stability of the bottom of the telescopic rod 1023 can be enhanced and tilting can be prevented.

[0039] In this embodiment, by setting a stepper motor 1029, when the height of the device needs to be adjusted, the stepper motor 1029 runs, which can rotate the threaded rod 1030. Through the limiting of multiple telescopic rods 1023, the threaded cylinder 1027 can be moved on the surface of the threaded rod 1030, thereby adjusting the position of the threaded cylinder 1027 on the surface of the threaded rod 1030, thus adjusting the height of the device. This allows the device to adapt to workers of different heights, making it more convenient to use. By setting a second electric push rod 1021, the operation of the second electric push rod 1021 can adjust the position of the placement plate 1022. When the placement plate 1022 moves down, it can provide space for the rotation of the workpiece 3. When the placement plate 1022 moves up, it is convenient for people to support the workpiece 3.

[0040] The working principle of the above embodiment is as follows: When in use, the workpiece 3 is placed on the top of the placement plate 1022. After placement, the first electric push rod 1010 runs and can push an L-shaped slide rod 1014 to move through the connecting rod 1019. Through the meshing of the sliding rack 1015 and the transmission gear 1012, the two clamping plates 1017 can be driven to move closer to each other, so as to clamp and fix the workpiece 3. After fixing, the welder 2 is started to weld the workpiece 3.

[0041] When it is necessary to flip the workpiece 3, the second electric push rod 1021 is activated, which can move the placement plate 1022 down. After the downward movement is completed, the rotary motor 103 is activated, which can make the rotary gear 104 rotate. Through the meshing of the rotary gear 104 and the ring rack 107, the rotary ring 105 can be driven to rotate, so that the rotary ring 105 rotates 180°, which can flip the workpiece 3. After flipping, the second electric push rod 1021 is activated again, which moves the placement plate 1022 to the bottom of the workpiece 3 to support the workpiece 3.

[0042] When the height of the device needs to be adjusted, the stepper motor 1029 runs, which can rotate the threaded rod 1030. Through the limiting of the telescopic rod 1023, the threaded cylinder 1027 can be moved on the surface of the threaded rod 1030, thereby adjusting the position of the threaded cylinder 1027 on the surface of the threaded rod 1030, thus adjusting the height of the device. This allows the device to be adapted to workers of different heights, making it more convenient to use.
