Technical Field

[0001] This utility model belongs to the field of tooling and fixture technology, and in particular relates to a hydraulic clamping tool for a housing. Background Technology

[0002] Tooling fixtures are indispensable process equipment in manufacturing. Like a craftsman's "specialized hands," they precisely position and firmly clamp parts to be processed, ensuring they remain in the correct position during cutting, welding, assembly, or inspection. Using fixtures not only significantly improves production efficiency and product consistency, simplifying and standardizing complex operations, but also effectively guarantees machining accuracy and reduces labor intensity. They are a core technological guarantee for achieving efficient, high-quality, and large-scale production.

[0003] With societal development, the demand for product precision is increasing, making the production of stable and qualified products particularly important; this is especially true for thin-shell aluminum products. These products are highly susceptible to deformation, as shown in the attached image. Figure 6 To reduce material costs and weight, several sinks 81 of the workpiece 8 are integrally formed by casting. Now, several assembly holes 82 need to be opened on the workpiece 8 to connect with various components. Since the workpiece 8 does not have a large flat area, traditional fixtures cannot stably clamp it when opening the holes. Moreover, the outer side of the inverted L-shaped connecting platform 83 lacks support, which can easily cause deformation when opening the holes.

[0004] To address the aforementioned issues, this application proposes a hydraulic clamping fixture for housings. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic clamping fixture for housings, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a hydraulic clamping fixture for a housing, including a bridge plate. The bridge plate is provided with a plurality of upper and lower corresponding lever cylinders and support platforms. The bridge plate is equipped with a plurality of support cylinders that form support at the bottom of the workpiece. The support cylinders and lever cylinders are staggered. The bridge plate is provided with rotating anti-fool bars, and a plurality of anti-fool bars are arranged sequentially along the outer side of the workpiece.

[0007] Furthermore, the anti-fooling rod is rotatably connected to the bridge plate via an eccentric rod fixed at its lower end, and the eccentric rod extends through to the lower end of the bridge plate and is fixed with a gear.

[0008] Furthermore, a connecting frame is provided at the bottom of the bridge plate, and several toothed plates are fixed on the connecting frame and respectively mesh with the gears at the bottom of each anti-fool rod. A drive cylinder with its output end fixed to the connecting frame is fixed at the bottom of the bridge plate.

[0009] Furthermore, a linear guide rod is fixed on the connecting frame, and a linear guide sleeve is fixed at the bottom of the bridge plate to slide in cooperation with the linear guide rod.

[0010] Furthermore, the bridge plate is provided with at least two fixed positioning pins, which are engaged with the grooves on the workpiece.

[0011] Furthermore, the bridge plate is provided with a plurality of chip removal holes corresponding to the assembly holes.

[0012] Furthermore, the support cylinder includes a first support cylinder and a second support cylinder, wherein the first support cylinder forms a support at the lower end of the inverted L-shaped connecting platform.

[0013] This utility model has the following beneficial effects: This invention uses multi-point lever cylinders and support platforms to stably press the workpiece onto the fixture, preventing vibration. At the same time, support cylinders at multiple points provide reverse pressing for the workpiece, further improving the stability of the workpiece during processing. This invention provides a series of anti-foolproof bars arranged along the periphery of the workpiece on the bridge plate. These anti-foolproof bars can laterally limit the workpiece at multiple points to prevent lateral deviation, and also serve to prevent mistaken placement of the workpiece.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] Please see Figure 1 - Figure 6 As shown, this utility model is a hydraulic clamping fixture for a housing, including a bridge plate 1, a bridge plate 1, a plurality of upper and lower corresponding lever cylinders 2 and support platform 3 are provided on the bridge plate 1, and a plurality of support cylinders are installed on the bridge plate 1 to form support at the bottom of the workpiece 8. The support cylinders and the lever cylinders 2 are staggered. The support cylinders are used to support the workpiece 8 at the weak and stress-requiring position during processing. Furthermore, the bridge plate 1 is provided with a rotating anti-fool bar 6. Several anti-fool bars 6 are arranged sequentially along the outside of the workpiece 8. The anti-fool bars 6 play an anti-fool role when the workpiece 8 is placed, ensuring that the workpiece 8 is placed accurately.

[0020] Furthermore, to enhance the lateral stability of workpiece 8 during processing, the anti-fool rod 6 is rotatably connected to the bridge plate 1 via an eccentric rod 61 fixed at its lower end. The eccentric rod 61 extends through to the lower end of the bridge plate 1 and is fixed with a gear 62. A connecting frame 7 is provided at the bottom of the bridge plate 1, and several toothed plates 72 are fixed on the connecting frame 7 and mesh with the gear 62 at the bottom of each anti-fool rod 6. A drive cylinder 71 with its output end fixed to the connecting frame 7 is fixed at the bottom of the bridge plate 1. In this embodiment, the meshing of multiple linear guide rods 73 and 63 is synchronized through the connecting frame 7, which facilitates the simultaneous operation of all anti-fool rods 6, making it convenient to use and structurally stable. It should be noted that the anti-fool rod 6 only forms a contact positioning on the side of the workpiece 8 and does not participate in the active lateral clamping.

[0021] Furthermore, in order to ensure the stability of the connecting frame 7 at the bottom of the bridge plate 1, a linear guide rod 73 is fixed on the connecting frame 7, and a linear guide sleeve 74 is fixed at the bottom of the bridge plate 1 to slide in cooperation with the linear guide rod 73.

[0022] Furthermore, in order to quickly position the workpiece 8 during placement, the bridge plate 1 is provided with at least two fixed positioning pins 5, which are engaged with the grooves 81 on the workpiece 8.

[0023] Furthermore, in order to prevent the accumulation of debris during the machining of the assembly hole 82, a number of chip removal holes 11 corresponding to the assembly hole 82 are provided through the bridge plate 1.

[0024] Furthermore, the support cylinder includes a first support cylinder 41 and a second support cylinder 42.

[0025] Since assembly holes 82 also need to be made on the inverted L-shaped connecting platform 83, but the inverted L-shaped connecting platform 83 protrudes upwards and lacks reliable support, it is easy to deform. Therefore, a first support cylinder 41 is set to form support at the lower end of the inverted L-shaped connecting platform 83 to prevent the inverted L-shaped connecting platform 83 from deforming during the machining of the assembly holes 82.

[0026] One specific application of this embodiment is: S1. Under normal conditions, the anti-fooling rod 6 is in the outward position. At this time, the space between the multiple anti-fooling rods 6 is relatively large. The workpiece 8 is placed on multiple support platforms 3. At this time, the two positioning pins 5 are respectively inserted into the two slots 81 on the workpiece 8 to complete the initial positioning. S2. Start the drive cylinder 71. The output end of the drive cylinder 71 drives the connecting frame 7, the toothed plate 72, and the linear guide rod 73 to move. After the gear 62 meshes with the toothed plate 72, it rotates the anti-fooling rod 6 along the eccentric rod 61. All the anti-fooling rods 6 form a lateral positioning of the workpiece 8 from the side. S3, the lever cylinder 2 presses the workpiece 8 onto the support table 3, and the lever plate on the lever cylinder 2 corresponds vertically to the support table 3. S4, the first support cylinder 41 and the second support cylinder 42 push upward to form support on the unclamped part of the workpiece 8.
