Description

Technical Field

[0001] The present application relates to the field of machining machine tool fixtures, and in particular to an array machining center machine tool fixture. Background Art

[0002] In the modern machining industry, machining center machine tools, as one of the core production equipment, play a vital role. These machine tools are widely used in the efficient production of complex parts with their high flexibility, diverse processing capabilities and high-precision processing characteristics. However, with the continuous improvement of the manufacturing industry's requirements for production efficiency and processing accuracy, the traditional single-piece clamping processing mode has gradually shown its limitations, especially when processing batch workpieces.

[0003] In the traditional machining process, the clamping of a single workpiece is not only time-consuming, but also depends on the operator's skill level, which easily leads to inconsistent clamping accuracy and affects the quality of the final product. In addition, frequent tool changes further reduce machining efficiency and increase non-cutting time, which is particularly prominent in large-scale production environments. This problem is particularly severe for workpieces that require multiple tool changes to complete different machining steps.

[0004] In view of the above challenges, it is particularly important to develop a fixture system that can fix multiple workpieces at the same time and ensure the precise and consistent positions of each workpiece. Traditional machine tool fixtures are often limited to single-piece clamping, or even if they can handle multiple pieces, it is difficult to achieve fast clamping and part replacement while maintaining high precision. Therefore, the market urgently needs an innovative solution that can not only improve the clamping speed and accuracy of the workpiece, but also effectively reduce the number of tool changes during the processing process, thereby greatly improving the overall work efficiency of the machining center.

[0031] The following is combined with Figure 1-6 This application is described in further detail. Example 1

[0032] The present embodiment discloses an array machining center machine tool fixture, including a base plate, a positioning block and a center pressure block. The base plate is provided with a plurality of positioning grooves arranged in an array and a plurality of plate bed fixing holes, which are used to fix the entire fixture on the machine tool workbench. The positioning block is installed in the positioning groove of the base plate, and the workpiece is accurately positioned by contacting the side wall of the positioning block. The center pressure block can be fixed on the base plate, and its function is to firmly fix the workpiece between the base plate and the center pressure block. The base plate is also provided with plate end fixing holes to further ensure the installation stability on the machine tool workbench.

[0033] The implementation principle of Example 1 is as follows: when using the fixture, first install the positioning block in the positioning groove of the base plate to ensure that the positioning block is stable and accurate. Then, place the workpiece between the positioning blocks, and position the workpiece by contacting the workpiece with the side wall of the positioning block. Finally, fix the center pressure block on the base plate to ensure its stability and processing accuracy by pressing the workpiece. This design not only improves the clamping efficiency of the workpiece, but also ensures the consistency and accuracy of batch workpiece processing. Example 2

[0034] The difference of this embodiment lies in the specific design of the central pressure block and the positioning block. The central pressure block is provided with pressure block bolt holes, and the base plate is provided with clamping holes corresponding to these bolt holes. By using the pressure block tightening bolts to pass through the pressure block bolt holes and cooperate with the clamping holes on the base plate, the central pressure block can be firmly fixed. This design makes the installation of the central pressure block more convenient and reliable, and further improves the efficiency of workpiece clamping.

[0035] In terms of the positioning block, the positioning block in this embodiment includes at least one transverse surface and at least one longitudinal surface, which allows the workpiece to be positioned in multiple directions, increasing the accuracy and flexibility of positioning. In addition, the positioning block can also include anisotropic surfaces to meet the positioning requirements of workpieces of different shapes, thereby improving the versatility and practicality of the fixture. Example 3

[0036] The difference of this embodiment lies in the further design of the positioning block. In this embodiment, the positioning block is designed as an integrated structure with multiple transverse surfaces and multiple longitudinal surfaces. This design allows multiple workpieces to be simultaneously abutted and fixed against the side walls of the transverse and longitudinal surfaces of the positioning block, thereby achieving efficient positioning of batch workpieces. This batch positioning method can significantly improve the working efficiency of the machining center, reduce the number of tool changes and clamping times, and reduce production costs. Example 4

[0037] This embodiment discloses an optimized array machining center machine tool fixture. On the basis of Example 3, the central pressure block is further designed as an integrated structure with multiple pressure block bolt holes. By tightening the bolts of multiple pressure blocks and passing through these bolt holes at the same time and cooperating with the clamping holes on the base plate, the workpiece can be more firmly fixed between the base plate and the central pressure block. This design not only improves the stability of the workpiece clamping, but also ensures the position accuracy of the workpiece during the processing, thereby improving the processing quality.

[0038] In addition, in this embodiment, the positioning block and the positioning groove have matching shapes and sizes, which ensures that the positioning block can be accurately installed in the positioning groove to provide stable positioning support for the workpiece. At the same time, the bottom plate, the center pressure block and the positioning block are all made of materials with high hardness and wear resistance, which greatly enhances the service life and stability of the fixture, enabling it to operate stably for a long time in a harsh working environment.

[0039] Through the detailed description of the above multiple embodiments, we can see that the array machining center machine tool fixture of the present application has shown significant advantages in structural design, ease of use and machining efficiency. These innovative designs enable the fixture to meet the stringent requirements of the modern mechanical processing industry for high precision, high efficiency and high stability, and provide strong technical support for the sustainable development of the manufacturing industry.

[0040] The above embodiments of the utility model are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
