Description

Technical Field

[0001] This utility model belongs to the field of fixture technology, and in particular relates to a quick clamping fixture for irregularly shaped workpieces. Background Technology

[0002] Irregularly shaped workpieces refer to parts with irregular shapes or non-standard specifications. They play an important role in various fields and scenarios, and are widely used in industries such as aerospace, automobile manufacturing, machinery and equipment, building structures, electronics and electrical appliances, and mold manufacturing.

[0003] In machining processes, quick-clamping fixtures are typically used to quickly and accurately position and fix workpieces. Their main function is to secure the workpiece in the correct position before machining, ensuring stability and accuracy during the machining process. Quick-clamping fixtures usually include various clamps, locating blocks, pressure plates, and other components, achieving rapid clamping through mechanical, hydraulic, or pneumatic means.

[0004] However, existing quick-clamping fixtures typically have the following problems:

[0005] 1. Primarily used for processing and clamping small profiles;

[0006] 2. High tooling costs make widespread adoption difficult;

[0007] 3. Poor tooling compatibility; generally, one tool is needed for each workpiece. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 4 This utility model embodiment provides a quick clamping fixture for irregularly shaped workpieces, used for quickly clamping irregularly shaped workpieces 5, including:

[0027] A base 1, on which two support plates 2 are symmetrically arranged, the support plates 2 being integrally formed with the base 1;

[0028] Two pressure plates 4 are fixedly installed on the base 1 by multiple fastening components 3.

[0029] This embodiment, through the special structural design of the fastening component 3, effectively solves the pain points of slow clamping and alignment of large irregular workpieces 5 compared with existing products. At the same time, it greatly improves the compatibility of tooling, saves the time of repeated tooling production, reduces the cost of processing tooling, reduces the waiting time of machine tools, improves equipment uptime and production efficiency, thereby reducing production costs.

[0030] Please see Figures 2 to 4 In a preferred embodiment of the present invention, the fastening assembly 3 includes a double-ended screw 31. The lower end of the double-ended screw 31 movably passes through the base 1 and extends into the mounting hole 11 fixedly opened at the bottom of the base 1. A lower locking nut 33 is movably locked in the mounting hole 11, and the lower locking nut 33 is threadedly connected to the double-ended screw 31.

[0031] Furthermore, the double-ended screw 31 also extends through the support plate 2 and the pressure plate 4, and is threadedly connected to the upper end of the pressure plate 4 to the upper locking nut 32. The support plate 2 and the pressure plate 4 are fixedly provided with a reserved hole 21 and a through hole 41 at the positions corresponding to the double-ended screw 31.

[0032] In practical application, this embodiment uses a double-headed screw 31 in conjunction with an upper locking nut 32 and a lower locking nut 33 to install the pressure plate 4, and uses the support plate 2 to quickly clamp and fix the irregular workpiece 5.

[0033] Please see Figure 3 and Figure 4 In another preferred embodiment of this utility model, the mounting hole 11, the reserved hole 21 and the through hole 41 can also be configured as a waist-shaped hole.

[0034] In practical applications, this embodiment allows for adjustment of the screw's installation position based on variations in workpiece shape or size through the provided waist-shaped hole, ensuring that workpieces of different shapes or sizes can be clamped on the same fixture, thereby improving the fixture's compatibility.

[0035] When using this fixture, first clean the clamping platform to ensure its levelness. Install the lower locking nut 33 in the mounting hole 11. Place the fixture stably on the clamping platform and adjust it to ensure that the upper plane of the fixture support plate 2 is parallel to the platform. Then, hoist the workpiece onto the fixture and adjust its alignment to ensure that it is perpendicular to the fixture base 1. Fine-tune the position of the double-ended screw 31 according to the workpiece shape to avoid interference between the workpiece and the double-ended screw 31. Install the pressure plate 4 and install and tighten the upper locking nut 32 in sequence. During the nut tightening process, reconfirm the workpiece's perpendicularity to ensure that it is normal after tightening. Hoist the fixture with the workpiece clamped onto the CNC machine tool and secure it to the machine tool platform through the preset mounting holes on the base 1, ensuring that the fixture base 1 and the machine tool platform are installed 0-0.

[0036] Please see Figures 1 to 4 In another preferred embodiment of this utility model, the fastening components 3 are configured to be at least four.

[0037] In practical applications, this embodiment effectively ensures the connection between the pressure plate 4 and the base 1 by setting the number of fastening components 3 and distributing them evenly on the two pressure plates 4, and further ensures the clamping effect of the pressure plate 4 and the support plate 2 on the workpiece 5 to be processed.

[0038] Please see Figures 1 to 4 In another preferred embodiment of this utility model, the pressure plate 4 and the support plate 2 have the same horizontal cross-section.

[0039] In practical applications, the cross-sectional design of the pressure plate 4 and the support plate 2 in this embodiment effectively adapts to the shape of the irregular workpiece 5, thereby ensuring the perpendicularity of the workpiece when clamping the irregular workpiece 5, which facilitates subsequent processing and ensures the standardization of workpiece processing.
