Description

Technical Field

[0001] This utility model relates to the field of machining tooling and fixture technology, and in particular to a multi-purpose jig suitable for the production of multiple small batches of parts. Background Technology

[0002] In the field of machining, the production mode of multiple varieties and small batches is widespread. In this type of production scenario, the production cycle of a single product is short, which usually cannot meet the production needs of a single processing equipment for a month. It is necessary to frequently switch between different types of products for processing. In the existing technology, the adaptation method between processing equipment and products is that one product corresponds to one set of dedicated tooling fixtures. That is, every time a product is switched, the tooling fixtures corresponding to the current product must be removed, and then the tooling fixtures dedicated to the product must be re-set, and repeated calibration and debugging operations must be performed. Especially when a single processing equipment needs to be compatible with the production of multiple products, the above switching process has significant defects. On the one hand, the process of removing, setting up and calibrating tooling fixtures consumes a lot of time and occupies valuable human resources, resulting in prolonged equipment downtime and serious waste of machine capacity. On the other hand, repeated tooling switching is prone to introducing installation errors, making it difficult to ensure the dimensional consistency of different products, thus affecting the product dimensional yield. The aforementioned problems not only reduce overall production efficiency but also increase production costs, becoming a critical technical challenge that urgently needs to be addressed in multi-variety, small-batch processing production. Therefore, it is imperative to develop a technical solution that is suitable for this type of production scenario to compensate for the shortcomings of existing technologies. Utility Model Content

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention.

[0020] Reference manual attached Figures 1 to 4 The present invention provides a multi-purpose fixture adapted for the production of multiple small batches of parts, comprising: a base 1, a multi-tool fixture assembly 2, and a combined fixing mechanism; The multi-tool fixture assembly 2 is provided with a left-side tooling fixing mechanism, a front-side tooling fixing mechanism, a rear-side tooling fixing mechanism, a right-side tooling fixing mechanism, and a top-side tooling fixing mechanism; The combined fixing mechanism includes a boss 3, a groove 4, a threaded hole 5, and a fixing bolt 6; The boss 3 is fixedly connected to the top of the base 1. The bottom of the multi-tool assembly 2 is provided with a groove 4 corresponding to the position of the base 1. Threaded holes 5 are evenly provided at the four corners of the bottom of the multi-tool assembly 2 and the position of the groove 4. Threaded holes 5 are also provided at the corresponding positions on the base 1. The fixing bolt 6 is screwed into the threaded holes 5 on the base 1 and the multi-tool assembly 2.

[0021] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following: In this embodiment of the utility model, the base 1 serves as the supporting foundation for the entire fixture, providing a stable installation platform for the multi-tool fixture assembly 2. The boss 3 is fixed to the top of the base 1, forming a precise positioning fit with the groove 4 at the bottom of the multi-tool fixture assembly 2, ensuring the positional accuracy of the multi-tool fixture assembly 2 during installation and avoiding displacement that could affect the machining accuracy of the parts. The threaded holes 5 at the four corners of the bottom of the multi-tool fixture assembly 2 and at the groove 4 are aligned with the corresponding threaded holes 5 on the base 1, and then tightened by screw bolts 6. The tightness of the threaded connection firmly fixes the base 1 and the multi-tool fixture assembly 2 into one unit, preventing relative displacement due to vibration during processing. This combined fixing mechanism not only achieves rapid positioning and installation of the multi-tool fixture assembly 2, but also ensures the stability of the overall structure, providing reliable structural support for subsequent multi-product switching processing and avoiding positioning errors and efficiency losses caused by repeated disassembly and assembly of traditional tooling.

[0022] In one possible implementation, the left tooling fixing mechanism includes a left side plate 211 and an A product positioning fixing bracket 212. The left side plate 211 is fixedly connected to the left side of the multi-tool assembly 2, and the A product positioning fixing bracket 212 is provided on the left side plate 211.

[0023] In this embodiment of the utility model, the left side plate 211 serves as the mounting carrier for the left-side tooling fixing mechanism. It is securely connected to the left side of the multi-tool assembly 2 via a fixed connection, providing a reliable mounting base for the A product positioning and fixing bracket 212. When A product needs to be processed, A product is placed in the corresponding mounting area of ​​the left side plate 211. The A product positioning and fixing bracket 212 precisely limits and fixes A product according to its structural dimensions and positioning requirements, ensuring that A product will not undergo horizontal or vertical displacement during processing. This mechanism, through its dedicated positioning and fixing design, adapts to the structural characteristics of A product, enabling rapid clamping and positioning of A product. It can meet the processing accuracy requirements of A product without additional tooling adjustments. Combined with the overall design of the multi-tool assembly 2, it enables rapid switching to other product processing, improving the efficiency of small-batch production.

[0024] In one possible implementation, the front tooling fixing mechanism includes a front side plate 221, a B product positioning groove 222, and a B product positioning fixing bracket 223. The front side plate 221 is fixedly connected to the front side of the multi-tool assembly 2. The B product positioning groove 222 is formed on the front side plate 221, and the B product positioning groove 222 is provided with the B product positioning fixing bracket 223.

[0025] In this embodiment of the utility model, the front side plate 221 is fixed to the front side of the multi-tool assembly 2, serving as a dedicated mounting reference surface for processing product B. Its flatness and stability directly ensure the processing accuracy of product B. The product B positioning groove 222 is opened on the front side plate 221 according to the outline and positioning reference of product B. When processing product B, the corresponding part of product B is placed in the product B positioning groove 222 to achieve preliminary accurate positioning and restrict the degree of freedom of movement of product B in the plane. At the same time, the product B positioning fixing bracket 223 on the product B positioning groove 222 further fixes product B in the positioning groove. Through the combination of the limiting effect of the positioning groove and the fastening effect of the fixing bracket, it is ensured that product B remains absolutely stationary during processing, avoiding positional displacement due to cutting force and other factors. This mechanism does not require the replacement of any parts. Simply put product B into the positioning groove and fix it with the fixing bracket to quickly enter the processing state, effectively shortening the product changeover time.

[0026] In one possible implementation, the rear tooling fixing mechanism includes a rear side plate 231 and a C product positioning fixing bracket 232. The rear side plate 231 is fixedly connected to the rear side of the multi-tool assembly 2, and the C product positioning fixing bracket 232 is provided on the rear side plate 231.

[0027] In this embodiment of the utility model, the rear side plate 231 is fixedly connected to the rear side of the multi-tool assembly 2 to form an independent C product processing area, which does not interfere with other product processing areas, ensuring the operating space and safety during the processing. Considering the structural characteristics and processing requirements of the C product, the C product positioning and fixing bracket 232 on the rear side plate 231 adopts an adaptive positioning method. When the C product is placed in the designated position on the rear side plate 231, the C product positioning and fixing bracket 232 fixes the key positioning surface of the C product through mechanical limiting, ensuring the stability of the C product's posture during the processing and meeting the requirements of the processing technology for the positioning accuracy of the C product. The design of this mechanism fully considers the structural differences of the C product, realizes the exclusive positioning and fixing of the C product, and can complete the processing switch between the C product and other products without disassembling or adjusting the tooling. This solves the pain point of frequent tooling changes in small-batch, multi-variety production and improves production continuity.

[0028] In one possible implementation, the right-side tooling fixing mechanism includes a right-side plate 241, a D-product positioning groove 242, and a D-product positioning fixing bracket 243. The right-side plate 241 is fixedly connected to the right side of the multi-tool assembly 2. The D-product positioning groove 242 is formed on the right-side plate 241, and the D-product positioning fixing bracket 243 is provided on the D-product positioning groove 242.

[0029] In this embodiment of the utility model, the right side plate 241 is fixed to the right side of the multi-tool assembly 2, serving as a dedicated installation reference surface for the processing of product D. Its flatness and stability directly ensure the processing accuracy of product D. The product D positioning groove 242 is opened on the front side plate 241 according to the outline and positioning reference of product D. The product D positioning fixing bracket 243 on the product D positioning groove 242 presses and fixes the positioned product D, further enhancing the installation stability of product D and ensuring that product D always maintains a precise processing posture during high-intensity operations such as cutting. This mechanism achieves rapid clamping and precise positioning of product D through the synergistic effect of the positioning groove and the fixing bracket. It can quickly switch to processing other products without additional tooling adjustments, adapting to the needs of small-batch production.

[0030] In one possible implementation, the top-side tooling fixing mechanism includes a top plate 251, an E-product positioning notch 252, and an E-product positioning fixing bracket 253. The top plate 251 is fixedly connected to the top side of the multi-tool assembly 2. The E-product positioning notch 252 is formed at the connection position of the left side plate 211, the front side plate 221, and the top plate 251. The E-product positioning fixing bracket 253 is disposed on the top plate 251 on one side corresponding to the E-product positioning notch 252.

[0031] In this embodiment of the utility model, the top plate 251 is fixed to the top side of the multi-tool assembly 2, and together with the left side plate 211 and the front side plate 221, forms the processing space for product E. The structural strength of the connection part ensures the stability of product E during processing. The positioning notch 252 of product E is opened at the connection position of the three parts. According to the shape structure and positioning reference of product E, it can accurately fit the edge contour or specific positioning part of product E to achieve the initial positioning of product E. At the same time, the three-dimensional space formed by the three parts is used to limit product E in multiple ways, restricting its movement in three-dimensional space. The positioning and fixing bracket 253 of product E on the top plate 251 corresponding to the positioning notch 252 of product E presses and fixes product E. Through the combination of the limiting of the positioning notch and the fastening of the fixing bracket, the position of product E is accurate and stable during processing. This mechanism makes full use of the three-dimensional space of the multi-tool assembly 2 to achieve exclusive positioning and fixing of product E. The processing of product E can be switched with other products without changing the tooling, further expanding the adaptability of one machine for multiple uses.
