Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and specifically discloses a clamping device for a clamp accessory assembly mechanism. Background Technology

[0002] Clamping technology has been developed and used in pipelines for liquids and gases, bringing great convenience to pipeline construction. Clamps are primarily made of stainless steel, which is rust-resistant and not easily deformed. Stainless steel clamps have excellent sealing performance because their rubber sealing rings and clamps utilize a unique sealable construction design. Furthermore, the sealing performance improves as the fluid pressure inside the pipe increases. Currently, clamps generally consist of the clamp body and a connector for locking the clamp opening. The connector is attached to the clamp body via a T-tee fitting. The T-tee fitting includes a nut and a T-shaped piece that connects to the nut. However, traditionally, the assembly of T-tee fittings is done manually, which is not only labor-intensive but also inefficient.

[0003] Chinese patent CN221416435U discloses a clamping device for a clamp fitting assembly mechanism, including a T-shaped tee fitting. The T-shaped tee fitting comprises a T-shaped part and a nut, and includes a base plate. A groove is formed at the upper end of the base plate, and two limiting components are symmetrically arranged about the groove at the upper end of the base plate. A vertical plate is fixedly connected to the left end of the base plate, and a fixing plate is fixedly connected to the upper right end of the vertical plate. A hydraulic cylinder is fixedly installed at the upper end of the fixing plate, and the telescopic end of the hydraulic cylinder passes through the fixing plate. This invention facilitates the positioning and clamping of the nut by setting limiting components on the base plate, and facilitates the hydraulic cylinder to press the lower end of the T-shaped part into the nut by setting a sliding groove, sliding ring, and return spring on the support plate, thus completing the assembly. Controlling the extension length of the hydraulic rod ensures assembly accuracy and high assembly efficiency.

[0004] The aforementioned document discloses a clamping device for a clamp assembly mechanism. In use, the nut is limited by two limiting springs. However, the elastic force of these two springs is difficult to guarantee is completely identical, resulting in inability to coaxially fix the nut and T-shaped part. This leads to deviations when the T-shaped part is pressed into the nut. Therefore, a clamping device for the clamp assembly mechanism is needed to solve this problem. Utility Model Content

[0005] This utility model proposes a pressing device for a clamp accessory assembly mechanism. Through the upper and lower symmetrical limiting mechanism and spring linkage structure, it realizes the rapid automatic centering and precise pressing of T-shaped parts and nuts, effectively solving the problem of assembly misalignment and significantly improving production efficiency and product qualification rate.

[0006] This utility model is implemented as follows: a clamping device for a clamp fitting assembly mechanism includes a bracket, a hydraulic cylinder is installed on the upper end face of the bracket, the output end of the hydraulic cylinder extends into the interior of the bracket and is fixedly connected to a pressure plate, a movable plate that can move up and down is movably connected inside the bracket through an elastic element, and a limit mechanism is provided at the bottom of the bracket and the upper end face of the movable plate, respectively used to position the T-shaped part and the nut of the tee fitting. The limiting mechanism includes grooves formed on the bottom of the bracket and the upper surface of the movable plate. Two symmetrically distributed clamping blocks are slidably connected to the inner wall of the grooves. V-shaped grooves are formed on the outer walls of the two clamping blocks facing each other. Limiting rings are fixedly connected to the bottom of the bracket and the upper surface of the movable plate. A rotating ring is rotatably connected to the outer wall of the limiting ring. Two circumferentially distributed and inclined slots are formed through the outer wall of the rotating ring. A connecting shaft that is slidably connected to the slots is fixedly connected to the upper surface of the clamping blocks. A second spring is provided between the inner wall of the groove and the clamping blocks.

[0007] As a preferred clamping device of the clamp accessory assembly mechanism of this utility model, the elastic element includes a sliding groove that runs through the left and right ends of the bracket. The inner walls of the two sliding grooves are fixedly connected to a limiting rod extending along the height direction of the bracket. The outer walls of the two limiting rods are slidably connected to a slider. The movable plate is fixedly connected between the two sliders. The outer walls of the two limiting rods are sleeved with a first spring located between the bottom of the bracket and the movable plate.

[0008] As a preferred clamping device for a clamping accessory assembly mechanism of this utility model, the lower end face of the movable plate is provided with a through hole communicating with the groove.

[0009] As a preferred clamping device in the clamping accessory assembly mechanism of this utility model, the outer wall of the rotating ring is provided with anti-slip texture.

[0010] As a preferred clamping device in the clamping accessory assembly mechanism of this utility model, the upper end face of the clamping block is flush with the upper end face of the movable plate or the bottom of the bracket.

[0011] As a preferred clamping device of the clamp accessory assembly mechanism of this utility model, the outer wall of the bracket is provided with a controller, and the hydraulic cylinder is electrically connected to the controller.

[0012] The beneficial effects of this utility model are: 1. The mechanical structure that drives the clamping blocks to move synchronously through the rotating ring, combined with the automatic reset clamping force provided by the spring, can quickly and accurately position the T-shaped parts and nuts coaxially, fundamentally ensuring the coaxiality of the two before pressing, solving the problem of easy skewing in previous pressing devices, and significantly improving assembly accuracy and pass rate.

[0013] 2. The symmetrically arranged limiting mechanisms form a systematic assembly fixture. Operators only need to repeat simple rotation and placement actions to complete the positioning of parts, and then the hydraulic cylinder completes the pressing in one go. This significantly reduces the difficulty of operation and the dependence on worker skills, and greatly improves assembly efficiency and product qualification rate. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-5A clamping device for a clamp fitting assembly mechanism includes a bracket 1, a hydraulic cylinder 3 mounted on the upper end face of the bracket 1, the output end of the hydraulic cylinder 3 extending into the interior of the bracket 1 and fixedly connected to a pressure plate 4, and a movable plate 2 that can move up and down is movably connected inside the bracket 1 through an elastic element. Limiting mechanisms are provided at the bottom of the bracket 1 and the upper end face of the movable plate 2, respectively used to position the T-shaped part 17 and the nut 18 of the tee fitting. The limiting mechanism includes a groove 9 formed at the bottom of the bracket 1 and the upper end face of the movable plate 2. Two symmetrically distributed clamping blocks 10 are slidably connected to the inner wall of the groove 9. V-shaped grooves are formed on the outer walls of the two clamping blocks 10. Limiting rings 11 are fixedly connected to the bottom of the bracket 1 and the upper end face of the movable plate 2. A rotating ring 12 is rotatably connected to the outer wall of the limiting ring 11. Two circumferentially distributed and inclined slots 13 are formed through the outer wall of the rotating ring 12. A connecting shaft 14 is fixedly connected to the upper end face of the clamping block 10 and slidably connected to the slots 13. A second spring 15 is provided between the inner wall of the groove 9 and the clamping block 10.

[0023] In this embodiment: Rotating the rotating ring 12 on the outer wall of the movable plate 2 causes the rotating ring 12 to drive two clamping blocks 10 to move synchronously in opposite directions via the slot 13 and connecting shaft 14. The T-shaped piece 17 is placed above the rotating ring 12, with its lower end passing through the through hole 16 on the outer wall of the movable plate 2. Releasing the rotating ring 12 causes the two clamping blocks 10 to move relative to each other under the elastic force of the second spring 15, thus centrally clamping and fixing the T-shaped piece 17 in the center of the through hole 16. Using the same method, the nut 18 is centrally fixed between the clamping blocks 10 at the bottom of the bracket 1, thereby coaxially fixing the T-shaped piece 17 and the nut 18. Activating the hydraulic cylinder 3 causes the pressure plate 4 to move downwards, thereby pressing the lower end of the T-shaped piece 17 into the nut 18, completing the assembly. This utility model, through two upper and lower limiting mechanisms, can efficiently and accurately achieve automatic centering and clamping of the T-shaped piece 17 and the nut 18, solving the problem of easy skew in previous clamping devices and significantly improving assembly accuracy and pass rate.

[0024] As a technical optimization of this utility model, the elastic element includes a sliding groove 5 that runs through the left and right ends of the bracket 1. The inner walls of the two sliding grooves 5 are fixedly connected to a limiting rod 6 that extends along the height direction of the bracket 1. The outer walls of the two limiting rods 6 are slidably connected to a slider 7. The movable plate 2 is fixedly connected between the two sliders 7. The outer walls of the two limiting rods 6 are sleeved with a first spring 8 located between the bottom of the bracket 1 and the movable plate 2.

[0025] In this embodiment: the limiting rod 6 provides precise linear guidance for the movable plate 2, preventing it from deviating during movement. The first spring 8 effectively absorbs the impact during the pressing process, thereby ensuring that the T-shaped part 17 and the nut 18 are accurately aligned while protecting the parts from damage.

[0026] As a technical optimization of this utility model, the lower end face of the movable plate 2 is provided with a through hole 16 that communicates with the groove 9.

[0027] In this embodiment, a through hole 16 communicating with the groove 9 is provided through the lower end face of the movable plate 2 to facilitate the passage of the T-shaped piece 17.

[0028] As a technical optimization of this utility model, the outer wall of the rotating ring 12 is provided with anti-slip texture.

[0029] In this embodiment: by providing anti-slip texture on the outer wall of the rotating ring 12, it is easier to increase the friction with the hand.

[0030] As a technical optimization of this utility model, the upper end face of the clamping block 10 is flush with the upper end face of the movable plate 2 or the bottom of the bracket 1.

[0031] In this embodiment, motion interference is prevented by making the upper end face of the clamping block 10 flush with the upper end face of the movable plate 2 or the bottom of the bracket 1.

[0032] As a technical optimization of this utility model, a controller is provided on the outer wall of the bracket 1, and the hydraulic cylinder 3 is electrically connected to the controller.

[0033] In this embodiment, the controller facilitates the normal operation of the hydraulic cylinder 3. It should be noted that the controller is a programmable logic controller (PLC), and the hydraulic cylinder 3 is a servo hydraulic cylinder with a built-in high-precision position encoder. It forms a closed-loop position control system with the controller, capable of receiving commands from the controller and providing real-time feedback on the precise displacement of the piston rod. Rexroth CYV-ME series or Parker HMA series servo hydraulic cylinders can be selected.

[0034] The working principle and usage process of this utility model are as follows: First, rotate the rotating ring 12 on the outer wall of the movable plate 2. The rotating ring 12 drives the two clamping blocks 10 to move synchronously in opposite directions through the slot 13 and the connecting shaft 14. Place the T-shaped piece 17 above the rotating ring 12, with its lower end passing through the through hole 16 on the outer wall of the movable plate 2. Release the rotating ring 12, and the two clamping blocks 10 move relative to each other under the elastic force of the second spring 15, centrally clamping and fixing the T-shaped piece 17 in the center of the through hole 16. Using the same method, centrally fix the nut 18 between the clamping blocks 10 at the bottom of the bracket 1, thereby coaxially fixing the T-shaped piece 17 and the nut 18. Start the hydraulic cylinder 3, which drives the pressure plate 4 downward, thereby pressing the lower end of the T-shaped piece 17 into the nut 18, completing the assembly.
