Description

Technical Field

[0001] The utility model relates to a press-fitting mechanism, in particular to a tooling for assembling a shell and a water nozzle of a liquid cooling device. Background Art

[0002] The electronic control system of new energy vehicles will generate a lot of heat during operation. Effective cooling is crucial to the performance, controllability and service life of the components in the electronic control system. At present, corresponding liquid cooling devices are usually used for cooling such electronic control systems. Such liquid cooling devices generally have a shell, on which a water nozzle is provided for the cooling liquid to enter and the cooling liquid to flow out after heat exchange. In the conventional structure, the water nozzle and the shell are assembled by rigid press-fitting. The press-fitting tooling for the above-mentioned products is mainly the following structure: including a tooling base plate, on which a positioning seat for positioning and clamping the shell and a carrier for carrying the water nozzle press-fitting mechanism are fixedly provided, and a shell positioning clamping mechanism is provided on the positioning seat, and the press-fitting mechanism can be arranged on the carrier in a linear motion. During the specific assembly, the shell is positioned and installed by the shell positioning clamping mechanism, and the water nozzle is clamped by the clamping part on the press-fitting mechanism. After the positioning and clamping of the two are completed, the corresponding hole positions on the water nozzle and the shell are coaxial, and the press-fitting mechanism moves linearly. Driven by the press-fitting mechanism, the water nozzle is aligned with the corresponding hole position and pressed into the installation.

[0003] According to the assembly requirements of the faucet and the shell, interference fit is selected for press-fitting. When designing the corresponding tooling, it is necessary to consider the problem of avoiding deformation or fracture damage of the parts when they are subjected to the pressure during the press-fitting process. At present, in view of this problem, in order to avoid fracture of the parts, support blocks that are shaped like the corresponding positioning cavities on the shell are added at the corresponding positions. In order to facilitate the flexible placement of parts, a gap is designed between the support block and the inner end face of the corresponding positioning cavity on the shell. This gap will cause the surfaces between the two to not be completely fitted during press-fitting (if the faucet is pressed from the front left to the right, then the surfaces between the two are the left end face of the support block and the inner end face of the corresponding cavity close to the left end face), resulting in insignificant support effect. There is also a risk of parts being fractured. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a tool for assembling the shell and the water nozzle of a liquid cooling device which has a simple structure and can effectively reduce the risk of parts being crushed.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A tool for assembling a shell and a water nozzle of a liquid cooling device, comprising a tool base plate, on which a positioning support block for positioning and supporting the shell and a clamping mechanism for realizing positioning and clamping of the shell are arranged, the positioning support block is contoured with a positioning cavity arranged below the shell and the two are clearance-matched after positioning and installation, a platform is arranged on the tool base plate, a pressing mechanism is arranged on the platform which can move linearly left and right, a clamping portion for clamping the water nozzle is arranged on the pressing mechanism, the positioning support block is fixedly arranged on the platform, and the platform is arranged on the tool base plate which can move linearly left and right.

[0007] The pressing mechanism can be movably arranged on the carrier platform through a linear guide mechanism, and has a simple structure and stable motion guidance.

[0008] The carrier is arranged on the tooling bottom plate in a movable manner through a linear guide rail mechanism, and has a simple structure and stable motion guidance.

[0009] The clamping mechanism includes a clamping platform, which is arranged on the tooling bottom plate, and a hollow cavity is recessed on the clamping platform corresponding to the position of the press-fitting mechanism, and the positioning support block is arranged in the hollow cavity, and the upper part of the positioning support block extends upward from the clamping platform, and a clamping oil cylinder for clamping and fixing the shell is arranged on the clamping platform; during assembly, the positioning support block extends into the positioning cavity to realize the positioning support of the shell, and the clamping and fixing of the shell is realized by the clamping oil cylinder. The structure is simple, and the setting of the hollow cavity makes the entire tooling structure more compact and the volume is relatively small.

[0010] The clamping platform is supported and arranged on the tooling bottom plate through a support seat. The position of the clamping platform is raised too high through the support seat to match the positioning support position of the shell, so as to realize effective clamping and fixing of the shell.

[0011] The pressing mechanism is driven by an oil cylinder and has a simple structure and is stable in use.

[0012] Compared with the prior art, the advantages of the utility model are: simple structure, the positioning support block is fixed on the carrier, and the carrier can be set on the tooling bottom plate for left and right linear movement. When not pressed, the shell is positioned and supported on the positioning support block through the positioning cavity set thereon, and there is a clearance fit relationship between the two. During press-fitting, under the positive force of the press-fitting mechanism, a reverse force will be generated. This reverse force will drive the carrier to move in the opposite direction of the press-fitting, thereby driving the positioning support block to move synchronously, so that the positioning support block and the corresponding end face in the positioning cavity of the corresponding shell are fitted together, which plays a supporting role in the press-fitting direction, thereby effectively reducing the risk of parts being crushed.

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] As shown in the figure, a tool for assembling the shell and water nozzle of a liquid cooling device includes a tool base plate 1, on which a positioning support block 2 for positioning and supporting the shell A and a clamping mechanism for realizing the positioning and clamping of the shell A are arranged, the positioning support block 2 is contoured with a positioning cavity A1 arranged below the shell A and the two are clearance-matched after positioning and installation, a platform 3 is arranged on the tool base plate 1, a pressing mechanism 8 is arranged on the platform 3 so as to be able to move linearly left and right, a clamping portion 81 for clamping the water nozzle B is arranged on the pressing mechanism 8, the positioning support block 2 is fixedly arranged on the platform 3, and the platform 3 is arranged on the tool base plate 1 so as to be able to move linearly left and right.

[0022] In this specific embodiment, the pressing mechanism 8 is movably arranged on the carrier 3 via a linear guide mechanism C. The structure is simple and the motion guidance is stable.

[0023] In this specific embodiment, the carrier 3 is movably arranged on the tooling base plate 1 via a linear guide mechanism D. The structure is simple and the motion guidance is stable.

[0024] In this specific embodiment, the clamping mechanism includes a clamping platform 4, which is arranged on the tooling bottom plate 1, and a hollow cavity 41 is recessed on the clamping platform 4 at a position corresponding to the pressing mechanism 8, and the positioning support block 2 is arranged in the hollow cavity 41, and the upper part of the positioning support block 2 extends upward from the clamping platform 4, and a clamping oil cylinder 5 for clamping and fixing the shell A is arranged on the clamping platform 4; during assembly, the positioning support block 2 extends into the positioning cavity A1 to realize the positioning support of the shell A, and the clamping and fixing of the shell A is realized by the clamping oil cylinder 5. The structure is simple, and the setting of the hollow cavity 41 makes the entire tooling structure more compact and relatively small in size.

[0025] In this specific embodiment, the clamping platform 4 is supported and arranged on the tooling base plate 1 through the support seat 6. The position of the clamping platform 4 is raised too high through the support seat 6 to adapt to the positioning support position of the shell A, so that the shell A is effectively clamped and fixed.

[0026] In this specific embodiment, the pressing mechanism 8 is driven by the oil cylinder 7. The structure is simple and the use is stable.

[0027] The positioning reference of the press-fitting of the tooling is pre-debugged. The shell A is positioned and supported by the positioning support block 2. After being clamped and fixed by the clamping cylinder 5, the side end face of the shell A opposite to the press-fitting mechanism 8 (shown as the left end face in the figure) has a hole A2 for installing the faucet B. The faucet B is clamped by the clamping part 81 on the press-fitting mechanism 8. At this time, the faucet B is coaxially matched with the corresponding hole A2. The cylinder drives the press-fitting mechanism 8 to make a linear motion to the right, and the faucet B is aligned and installed in the corresponding hole A2. At this time, there is a rightward force and a leftward reverse force. This force drives the carrier 3 to make a linear motion to the left, and the positioning support block 2 moves to the left accordingly, so that its left end face fits with the corresponding end face in the positioning cavity A1, and support is achieved here.
